What is a wall piece? What are the construction requirements for the wall pieces?

Connecting wall pieces refer to the components that connect the scaffolding body with the main structure of the building and can transmit tension and pressure.

1. The flexible tie parts are tied by thin steel bars, ropes, double or multiple strands of iron wire. It only bears tensile force and mainly plays the role of preventing the scaffolding from cambering, and does little to help the scaffolding stability performance (i.e., stable bearing capacity). This method can generally only be used in the external scaffolding of buildings below 10 floors, and a certain number of rigid tie pieces must be set accordingly to withstand the action of horizontal pressure.

2. The rigid wall connecting parts are made of rigid tie rods or components such as steel pipes, fasteners or embedded parts. Its connection structure can withstand both tensile force and pressure, and the connection and fixing mode of the attached wall end can be determined according to the engineering conditions.

A wall piece is a component that connects scaffolding to a building. The connecting wall pieces composed of steel pipes, fasteners or embedded parts are rigid connecting wall pieces, and the connecting wall pieces composed of steel bars are flexible connecting wall pieces. In double-row scaffolding, rigid wall pieces are generally used.

The spacing of the connecting wall pieces refers to the distance of adjacent connecting wall pieces, which can usually be arranged as three steps and three spans, two steps and three spans, and two steps and two spans.

6 4 2 The arrangement of the connecting wall pieces shall comply with the following provisions:

1) It should be set close to the main node, and the distance from the main node should not be greater than 300mm;

2) should be set up from the first longitudinal horizontal rod of the bottom layer, when the place is difficult to arrange, should be fixed by other reliable measures;

3) It is advisable to give priority to the diamond-shaped layout, and can also use square and rectangular layout;

4) The two ends of the slotted and open scaffold must be provided with wall pieces, and the vertical spacing of the wall pieces should not be greater than the floor height of the building, and should not be greater than 4m (2 steps).

6 4 3 Pairs of single-row and double-row scaffolding with a height of less than 24m should be reliably connected with the building by rigid wall pieces, and the attached wall connection method with tension bars and top braces can also be used. It is strictly forbidden to use flexible wall pieces with only tension reinforcements.

6 4 4 pairs of double-row scaffolding with a height of more than 24m must be reliably connected with the building by rigid wall pieces.

6 4 5 The construction of the connecting wall pieces shall comply with the following provisions:

1) The connecting wall rod or tension bar in the connecting wall piece should be set horizontally, when it cannot be set horizontally, one end connected with the scaffold should be connected obliquely, and should not be connected upward;

2) The wall pieces must be constructed in a way that can withstand tension and compression. The use of tension ribs must be equipped with jacking supports, which should be reliably topped on concrete ring beams, columns and other structural parts. The tendon should be twisted into one strand with a diameter of more than two steel wires of 4mm, and no less than 2 strands should be used; It is also possible to use steel bars with a diameter of not less than 6mm.

6 4 6 When the lower part of the scaffold cannot be connected to the wall for the time being, a throwing brace can be erected. The throwing brace should be reliably connected with the scaffold by means of a long rod, and the inclination angle with the ground should be between 45° and 60°; The distance from the center of the connection point to the main node should not be greater than 300mm. The throwing brace should be removed only after the wall piece is erected.

6 4 7 When the height of the erection exceeds 40m and there is wind vortex, the wall measures to resist the upswing should be taken.

What if the old house is not buried.

What is the specific content of the construction requirements of the <> connecting wall pieces, the following Zhongda Consulting will answer for you.

According to the requirements of the "Safety Technical Code for Fastener-type Steel Pipe Scaffolding for Building Construction" (JGJ130-2011), the scaffolding connecting wall pieces should meet the following requirements:

1. The location and quantity of the wall pieces should be determined according to the special construction plan, which can usually be arranged as three steps and three spans, two steps and three spans and two steps and two spans, etc., and generally each wall piece covers an area of 20 40 square meters.

2. The arrangement of the connecting wall pieces should be close to the main node, and the distance from the main node should not be greater than 300mm; It should be set up from the first longitudinal horizontal travel pole at the bottom floor, and when it is difficult to set up, other reliable measures should be used to fix it; Preference should be given to a diamond-shaped arrangement, or a square, rectangular arrangement.

3. The two ends of the open scaffold must be provided with connecting wall pieces, and the vertical spacing of the connecting wall pieces should not be greater than the floor height of the building, and should not be greater than 4m.

4. The connecting wall rod in the connecting wall piece should be set horizontally, and when it cannot be set horizontally, it should be connected diagonally to one end of the scaffold.

5. The connecting wall pieces must be constructed that can withstand tension and pressure. For double-row scaffolding with a height of more than 24m, rigid wall pieces should be used to connect with the building.

6. When the lower part of the scaffold cannot be connected to the wall for the time being, anti-overturning measures should be taken. When erecting the throwing brace, the throwing brace should be a long-length rod and fixed on the scaffold with a rotating fastener, and the inclination angle with the ground should be between 45 ° and 60 °; The distance from the heart of the peib heart to the main node in the connection point should not be greater than 300mm, and the throwing brace should be removed after the wall piece is erected.

7. When the elevation exceeds 40m and there is wind vortex, the wall measures to resist the rising and tumbling effect should be adopted.

(1) The location and quantity of the connecting wall pieces shall be determined according to the special construction plan, and the setting of the number of scaffolding connecting wall pieces shall meet the calculation requirements of the "Safety Technical Code for Fastener-type Steel Pipe Scaffolding in Building Construction" (JGJ130-2011).

The meaning of the wall pieces on the building is as follows:

Connecting wall pieces generally refer to the components that strengthen the stability of other structures by connecting with reliable fixed ends, and are used in construction projects to connect the scaffolding body with the main structure of the building and transmit tensile force and pressure. The attached wall connection realized by using connecting wall pieces plays a very important role in strengthening the overall stability of the scaffold, improving its stable bearing capacity and avoiding major accidents such as dumping or collapse.

Connecting wall pieces refer to the components that connect the scaffolding body with the main structure of the building and can transmit tension and pressure. It can be replaced by embedded parts, provided that the composite requirements are combined!

The so-called "step" refers to the distance between the axes of the upper and lower horizontal crossbars of the scaffolding. Generally.

The so-called "span" refers to the axial distance between adjacent upright poles of scaffolding. Generally.

Details JGJ130-2001 Three-step two-span refers to the method of setting up the wall pieces, generally under normal circumstances, the scaffolding and the wall pieces are vertically set up by the compartment (each layer of the height of the layer is set), and the horizontal setting distance is your three spans (the specific distance should be determined according to the project situation).

Hope it helps.

Outer shelf? It is called a connecting wall member.
