What needs to be inspected for factory front wheel buckle scaffolding?

Wheel buckle scaffolding does not need the help of compressors, which can ensure a reasonable distribution of tension and pressure, ensure a certain balance while ensuring very good stable performance, and prevent the unsafe factors of some active compressors; In the process of construction, there are no cumbersome operation steps in the construction of the new wheel buckle scaffolding, and the construction is fast and simple. In a word, the wheel-buckle scaffold has very good performance and is safe and reliable. In the process of using the product, we also need to look at the service life, which is also what we need to test, and we need to pay attention to this more important factor in the process of testing.

In the wheel buckle scaffolding product, we test the firmness performance, because this product is more critical in the process of use, so we need to pay attention to this problem, if the product is not strong, it can not be used normally. The formwork support shall be inspected by the technical person in charge of the project to organize the design and management personnel of the formwork support, and the formwork support shall be inspected with a focus on the formwork support, and the formwork support shall be provided with inclined rods according to the construction plan and the corresponding basic structural requirements of these regulations; The cantilever length of the adjustable bracket and the adjustable base extending out of the horizontal rod must meet the design limit requirements; The horizontal rod buckle joint should be pinned tightly; The foundation of the vertical rod should meet the requirements, and there is no loosening or suspension between the vertical rod and the foundation. The inspection and acceptance of scaffolding should focus on inspection, and the wall pieces should be set up perfectly; There should be no uneven settlement of the upright rod foundation, and the contact between the upright rod adjustable base and the foundation surface should not be loose or suspended; The oblique rod and scissor brace should meet the requirements; The outer safety vertical net and the inner interlayer horizontal net should meet the requirements of the special construction plan; The re-inspection record of the supporting parts used in turnover before use; The erection of construction records and quality inspection records should be timely and complete.

There should be a steel pipe bracket product identification and product quality certificate; There should be the main technical parameters of the steel pipe bracket product and the product instruction manual; The components entering the site shall be sampled and inspected for pipe diameter and component wall thickness, and shall also be subject to visual inspection, and the appearance quality shall comply with the provisions of Article 1 of these regulations; If necessary, the quality of the support members can be sampled and tested. The formwork support shall be inspected and accepted in the following stages: after the completion of the foundation and before the formwork support is erected; After the high formwork of more than 8m is erected to half the height; After reaching the design height, a comprehensive inspection and acceptance should be carried out; Inspection of special circumstances after strong winds, heavy rain and heavy snow above level 6; Downtime for more than one month before resumption of use.

The formwork and its support system should have sufficient strength, stiffness and stability, and the supporting surface of the formwork should be flat and compacted, and there should be sufficient bearing area. After the construction of the formwork project, the embedded and reserved holes should also be checked to ensure that the location, size and quantity of the embedded and reserved holes must be accurate. The product quality has passed the inspection of the National Construction Engineering Quality Supervision and Inspection Center, and all meet the requirements of the inspection standard GB 24911-2013, with high welding strength and no cracks.

Scaffolding steel pipe wall is thick and firm, which is the best choice for construction lessors, wheel buckle scaffolding formwork square timber rental industry. The wheel buckle scaffold is a vertical rod crossbar is 3700 yuan tons, all of which are first-class steel pipes, material Q235, steel pipe wall thickness, for customers to choose, the most general wall thickness is, qualification inspection report, factory certificate, complete.

In the early stage, the special construction plan design of the support system should be done, and the general contractor should be positioned by the pay-off line, so that the support system is horizontal and vertical, so as to ensure the setting of the scissor brace and the overall connecting rod in the later stage, and ensure its overall stability and anti-overturning. The installation foundation of the wheel-type scaffolding must be compacted and leveled, and concrete hardening measures must be taken. The elevation range of the bottom plate of the beam plate of the same elevation should be used for the wheel-buckle scaffolding, and the tensile force and the axial pressure (critical force) of the vertical rod should be checked for the crossbar when the single member support frame with a large height and span is used to ensure the stability and safety of the frame.

After the erection of the frame body is completed, enough scissor braces should be added, and enough horizontal tie rods should be added at the distance between the jacking support and the cross bar of the frame body 300-500mm, so that the overall stability can be reliably guaranteed. At present, China's Ministry of Construction has not issued industry standards and specifications for wheel buckle scaffolding, but it has begun to be widely used on construction sites, of course, it is hoped that the relevant departments will formulate corresponding specifications, so that the correct use of wheel buckle scaffolding in the project has a reliable basis. Support for building formwork works (including road and bridge construction), especially for high formwork; exterior scaffolding of high-rise and low-rise buildings; large, medium and small warehouse shelves (three-dimensional shelves); "Working platforms" for high-altitude work in renovation works and mechanical and electrical installations, internal and external scaffolding in the shipbuilding industry

concerts, sports meetings, temporary stands, viewing platforms and stage scaffolding, etc.; Mobile sheds for construction units. Wheel-buckle scaffolding has achieved three firsts in the history of scaffolding development: that is, the "first" has realized that the steel pipe scaffold has no special locking parts in the structure; The "first" achieves that there are no moving parts on the steel pipe scaffolding; The "first" realizes China's independent intellectual property rights for the overall new steel pipe scaffolding.

So far, the product has been well received by users at home and abroad, and has been adopted by domestic road and bridge, municipal, housing construction and other units, and has been widely used in foreign projects such as Thailand Outer Ring Road Viaduct, Suzhou Dan Lowe Dam, Shenyang Jianshe Avenue Overpass in China, Beijing Military Museum, Beijing Tiananmen Square, Zhengxi Passenger Dedicated Line, Wuhan-Guangzhou Passenger Dedicated Line, Harbin-Dalian Passenger Dedicated Line, Beijing-Shanghai High-speed Railway, Yunnan Kunming Century City and other projects.

After the removal of the large piece of wheel buckle scaffolding, there must be corresponding ramps and passages, which are reinforced first, so as to ensure the integrity of the structure and the safety unchanged after dismantling. If there is an external power line nearby, it must be removed in isolation. When disassembling the pole parts of the wheel buckle scaffolding equipment, the pole should be fixed first, and the last two buckle removal points must be coordinated and consistent, and when untying the knot related to another person, the other party should be notified first to prevent the occurrence of falling incidents.

Do not make contact between the pole and the wire. In the process of dismantling the wheel buckle scaffolding, we strictly pay attention not to damage the nearby doors and windows, water droppers and eaves tiles and other structural buildings. The construction personnel engaged in the dismantling of the wheel buckle scaffolding equipment must fasten the corresponding safety belts, wear the corresponding safety helmets, and have complete safety protection measures.

In the process of demolition, it is necessary to follow the principle of top-down and post-construction first. That is, the railings, scaffolds, diagonal braces, scissor braces are removed first, and then the small crossbars, large crossbars and vertical rods and other components on the equipment are disassembled, and at the same time, they should be disassembled in accordance with the principle of one-step clearing, and it is strictly forbidden to operate up and down at the same time. For all dismantled materials, it is required to be firmly tied with ropes and slowly transported down with pulleys, and it is strictly forbidden to drop them directly from above.

Wheel buckle scaffold is a new type of convenient support scaffold, which is a bit similar to the bowl buckle frame and is better than the bowl buckle frame, and its main characteristics are: it has reliable two-way self-locking ability; No moving parts; Transportation, storage, erection, dismantling is convenient and fast; 4. Reasonable stress performance; It can be adjusted freely; Standardized packaging of products; The assembly is reasonable, and its safety and stability are better than those of the bowl buckle type and better than the portal scaffolding; In practice, it is shown that as a single-span, multi-span continuous beam and frame structure house formwork support system with a beam span of less than 15m and a clearance layer height of less than 12m, its stability and safety are better than that of bowl buckle scaffolding, and better than that of portal scaffolding.

When the steel pipe is seriously rusted, bent, flattened, or cracked, it should not be used to avoid accidents. Double-row scaffolding must be used, and single-row scaffolding is strictly prohibited. Seat belts must be used properly when removing scaffolding and must be supervised by a dedicated person.

Fences or warning signs should be set up around the perimeter. Non-staff members are not allowed to enter. When dismantling the large crossbar of the scaffold, the middle buckle should be removed first, and then the two-end buckle should be removed.

It is strictly forbidden to throw scaffolding poles, scaffolding boards, and steel pipes downward. Shigatse wheel buckle scaffolding|The unit price of disc buckle scaffolding, there was no specific industry regulation before, the conditions in the engineering work were poor, and the construction error was large, which caused the practice of cantilevered scaffolding to be non-standardized, and the quality of the project was seriously reduced. For example:

There is a slight vertical displacement of the cantilever beam after being subjected to pressure, the horizontal displacement of the cantilever beam is difficult to control, and the on-site construction quality of the single-sided horizontal weld of the two steel bars is not strictly controlled. The diagonal bracing device of the wheel-buckle scaffold fixes the diagonal brace rod and the scaffold upright rod by supporting the crossbar heel character, so that the diagonal brace rod and the scaffold upright rod form a triangular structure, and the supporting strength of the diagonal brace rod is improved by using the coordination of the triangular structure.

Cantilever scaffold application technology cantilever scaffold cantilever frame cantilever support structure setting to be determined by design calculation, can not be laid at will, pin early setting principle: cantilever beam spacing according to the cantilever frame body vertical rod longitudinal distance setting, each longitudinal distance set one. Scaffolding is a very common product at present, I believe that many people want to know how much scaffolding is a pair, the types of scaffolding are particularly many, so it is not fixed, and at the same time to know what the highlights of scaffolding are, only by understanding scaffolding can we better implement the use, although scaffolding is used more in ordinary times, there are people who really understand lead scaffolding or there are not many.

When the height is more than 15m or the height is close to 15m, but the exterior wall doors, windows and decorative area exceeds a large proportion of the surface area of the exterior wall (or the exterior wall is a cast-in-place concrete wall, and the light masonry is a large block wall), it is calculated as a double row of scaffolding. When the height of the building exceeds 30m, the collapse of the double-row scaffolding of the section steel lifting platform can be calculated according to the project situation. The composition of the wheel buckle scaffold comprises the main frame, the scaffold pedal, the roof beam, the winch, the steel cable, the transportation room, the ceiling, and is characterized in that:

The main frame is formed into a cube by the array of four columns of the group, and the inner frame of the main frame is provided with at least one layer of scaffolding pedals, and each layer of scaffolding pedals surrounds the inner wall of the main frame to form a "back" shaped construction platform; The oblique rod head is a rotatable joint, and the oblique rod head is fixed with the steel pipe body with rivets.

Our disc scaffolding is easy and fast, steel pipe scaffolding is quite easy and fast to build, in addition to it is not very mobile, wheel buckle scaffolding can meet a wide range of high-strength operations. Our double-row steel pipe scaffolding is extremely flexible, in addition to the high safety factor, it can also be freely disassembled, and different forms of scaffolding can be built according to different practical needs. The company is a professional and modern wheel buckle scaffolding R & D and production enterprises, Tan Zhe is committed to professional research and development, production, manufacturing and sales of various types of wheel buckle scaffolding products.

When installing, if the construction foundation is too low, drainage facilities should be used, and the filling of the pole should leave the mound above the ground to prevent the equipment from accumulating water below. When the height is less than 7 meters, it is necessary to set up a method of throwing braces to ensure the stability of the scaffolding, and when the height exceeds 7 meters, it is necessary to connect with the building.

The on-site test of wheel buckle scaffolding generally adopts a buckle steel pipe scaffold testing machine, combined with high-precision sensors, to achieve high-precision, wide-range, and multi-functional servo control.

Effectively use computer technology to preset, automatically measure, control, data process, draw various curves and print various parameters of the testing machine, and complete all the tests of the mechanical properties of the wheel-buckle steel pipe scaffold on one equipment.

The wheel-buckle steel pipe scaffold testing machine needs to meet the requirements in the "Safety Technical Regulations for Wheel-buckle Steel Pipe Scaffolding".

The field test of wheel buckle scaffolding mainly tests the following three items:

1. Shear strength test of wheel disc assembly after welding;

2. Shear strength test of crossbar plug welding;
