How to improve the installation accuracy of steel structure workshop

The top surface of the steel structure is not only the installation of lamps and lanterns, the finished tube chandelier is generally equipped with a metal installation base, and the wires should also be installed and laid, and the junction box is preset at the position of the lamps and lanterns while laying the wire pipe on the top surface, and the lamps and lanterns can be installed on it, if the lamps and lanterns are very heavy, such as the lamps and lanterns with positive flowers, or mixed lights, their lampshades are very large, and it is recommended to install them directly on the metal beams.

Many users will consider the cost problem in the construction of steel structure workshops, so that the height of the plant is low, and the height is not enough in the later use, but the dismantling of the entire plant will cause a waste of materials and costs.

At present, I want to raise the "steel structure workshop."

It's still a difficult job. Because the general plant has thousands or even tens of thousands of square meters, it is not easy to "raise the steel structure plant as a whole", which requires equipment that can lift the tonnage level and lift the plant as a whole.

It is recommended to find a closer steel structure engineering company to the site to understand the situation, and put forward the transformation requirements to discuss the feasibility of the plan, design node drawings, and formulate a construction period transformation plan. Understand the cost.

Generally speaking, the badminton court must be at least 13 meters high. With the addition of roof lighting, air conditioning and other facilities, it should be 15 meters.

When implementing, it is necessary to draw drawings first, and only after accurate measurement and calculation can it begin, and it is necessary to obtain the data of lighting manufacturers and air conditioning manufacturers.

Remember that the roof must be made of light-transmitting materials, so that you can save yourself a lot of expenses for turning on the lights during the day.

There is also a badminton hall to build, changing rooms are essential, and lockers can invisibly attract some regulars for you and make the players feel like they are at home.

In addition, there is no need to say much about refrigerators, toilets, etc.

Fees for badminton courts are available on a per-session basis and on a time-based basis.

We have 10 fast wooden floors and 20 fast plastic floors for an hour.

10 fast per hour;

7 fast per hour (because it is hotter during this time).

15 fast per hour (this is the most comfortable time of the day to play).

20 fast every hour (to turn on the lights·· ）

That's it, is there anything else you can add or send me a message.

Abstract:The construction quality of the steel structure workshop mainly focuses on the control in the construction process, and only by strengthening the control in the construction process can the overall quality of the steel structure be improved. Keywords:

First, the preface with the rapid development of the economy and the construction industry, industrial plants continue to emerge, steel structure workshops are bound to develop rapidly as a new type of industry, but with the construction of steel structure workshops, a large number of factors affecting the quality of steel structures continue to emerge, such as the installation accuracy of components, connection strength, construction methods, installation measures, etc., in order to improve the overall quality of steel structure workshops must take effective governance measures and improvement methods, This paper analyzes and elaborates on the points that should be paid attention to and controlled in the construction process of the steel structure workshop, and provides a certain theoretical reference for improving the overall quality of the steel structure workshop. (2649 words remaining).

The foundation of the steel structure workshop is usually a separate foundation, which is designed according to eccentric compression.

For the portal rigid frame steel structure workshop with low height and no crane, the connection between the column base and the foundation is usually designed according to the hinge. The top surface of the foundation is only a few degrees subject to the vertical pressure generated by the superstructure and the horizontal force generated by the wind load. The additional eccentric bending moment on the bottom surface of the foundation caused by the horizontal wind load is small, and the foundation design is relatively simple.

For portal rigid frame steel structure workshops and steel row frame structure workshops with high height and bridge cranes, especially when the crane tonnage is large (two 20t cranes or larger in a single span), in order to effectively improve the anti-lateral stiffness of the structure to control the lateral displacement, the column base is usually designed as transverse rigid jointed and longitudinally articulated. The factory is indulged.

The horizontal load is transmitted to the top surface of the foundation through the inter-column support. In the early direction of the transverse palace, because the steel structure has a light weight, the structure has a long natural vibration period, and the horizontal effect is relatively small, and the transverse horizontal load that plays a controlling role is usually the wind formula of the horizontal braking load of the crane, and the axial force of the two rods can not be equal. The formula is based on the elastic stability theory.

From the perspective of improving the installation accuracy of the steel structure workshop, some problems and specific control methods that must be attached great importance to in the main links such as production, transportation and installation are analyzed and summarized.

1. Control of the production and transportation of steel structure workshops.

Therefore, it is necessary to accurately grasp the straightness and twist of the steel column, the distance between the connecting hole of the column and the beam to the bottom plate of the column, the machining accuracy of the connecting hole itself, the straightness of the roof beam and the machining accuracy of the column and beam connecting plate, the position size of the tie rod or the supporting connecting plate on the beam and column relative to the position size of the beam and column itself, the position size of the purlin plate, etc.

Second, the quality control of the installation process of the steel structure workshop.

Before the installation of the steel structure workshop, it is necessary to do a good job in the preliminary work. For example, before hoisting, the installer should retest the component, and only if the component is not deformed and the installation size is correct, it can be hoisted. In addition, under the premise of confirming that the concrete strength of the foundation meets the requirements of the specification, the pre-embedded bolts or cup mouth of the steel column foundation should also be detected, and if the position of the foundation and the elevation size are found to be deviated, the position should be recorded to adjust the position of the steel column.

When installing a roofing steel frame system, sometimes there is a contradiction between the installation of roof supports and roof purlins. If the roof support is installed first, the roof purlin cannot be hoisted; If the roof purlin is installed first, the roof support is inconvenient to hoist. Our usual practice is to first hang the roof purlins in batches on the roof beams and fix them, and the purlins in the same span can be divided into 4 or 5 batches, and they must be fixed after stacking.

Let the crane boom stretch out of the roof from the gap between the batches of purlins, and after the roof support is hoisted and fixed, the roof purlins are then rolled out, and this construction sequence is very important. Considering that the installation of the envelope and the main structure is often not carried out by the same construction unit, it is necessary to have a unified command and coordination by an experienced manager. This not only avoids mutual interference between construction units, but also improves the safety of the working at height.

In the above installation process, it needs to be reminded that if there is a crane girder system in the workshop, and the space distance between the crane girder and the roof is not enough for the boom of the crane to use, the crane girder should be installed before installing the roof support; If the crane girder is located at a large distance from the roof space, it can be installed later. In general, it is best to lift the crane beam as soon as possible, which is also beneficial to the stability of the entire row frame.
