The construction of the utility model is more convenient, the connection with the wall body is firmer, and the scaffolding is more stable and safe.

Description

Pull-type screw-to-wall fittings

technical field

The utility model relates to a connecting piece, in particular to a pull-type screw-rod connecting wall piece.

Background technique

The traditional scaffolding and wall parts cause great disadvantages in the subsequent brick wall masonry. The brick wall must leave a large hole in the position of the wall part, which will cause damage to the building structure. The hole can only be sealed after the scaffolding is removed and the inner and outer walls are wiped Ash, resulting in easy water seepage in the hole plugged position, and the follow-up hole repair workload is relatively large. Moreover, the traditional connecting wall parts cannot be installed in the concrete shear wall, which causes the stability of the external scaffold to be weakened in the shear wall part, which brings safety hazards; if the connecting wall parts are installed in the shear wall part, holes must be generated, which will affect the shear force wall structure.

SUMMARY OF THE INVENTION

The utility model aims at overcoming the defects of the prior art, and provides a pull-type screw-rod connecting wall piece, which is more convenient for scaffolding construction on the outer wall, more firmly connected with the wall body, and more stable and safe for the scaffolding.

In order to solve the problems of the technologies described above, the utility model is achieved in that:

A pair of pull-type screw wall parts, characterized in that: it includes a screw, steel pipe, casing, steel plate and nut; the casing is pre-embedded in the concrete structure, the steel pipe is connected to the scaffold and the steel pipe is close to the concrete structure One end bears against the outer wall of the concrete structure, and the casing is docked with the nozzle of the steel pipe; the screw passes through the steel pipe and the casing, and steel plates are respectively installed at both ends of the screw and fixed by nuts.

The feature of the pull-type screw-connected wall piece is that the steel pipe and the scaffolding are connected by fasteners.

The beneficial effects of the utility model are: the construction quality is easy to control: the wall parts are pre-processed and used after acceptance, the on-site dismantling is easy, and the scaffolding wall quality is easy to control; the operation is simple: any construction personnel can quickly master the operation method, and the construction speed is fast , no damage to the construction formwork; the removal of the wall parts is convenient and does not affect the construction of the exterior wall, there is no hole and repair in the exterior wall, it will not cause water seepage in the exterior wall, and will not damage the building structure; it can effectively reduce the construction cost: the wall parts are connected after use Long steel bars can be reused. The wall connecting parts can be processed with engineering surplus materials to reduce the consumption of engineering materials; the connecting wall parts can be connected with concrete components or steel components.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Fig. 1 is the structural representation of the utility model.

Detailed ways

As shown in Figure 1: a pair of pull-type screw-connected wall parts, it includes a screw 1, a steel pipe 2, a sleeve 3, a steel plate 4 and a nut 5; the sleeve is embedded in the concrete structure, and the steel pipe is connected to the On the scaffolding, one end of the steel pipe against the concrete structure is against the outer wall of the concrete structure, and the casing is docked with the nozzle of the steel pipe; the screw passes through the steel pipe and the casing, and the two ends of the screw are respectively installed with steel plates and fixed by nuts; Fasteners 6 are used to connect the steel pipes to the scaffolding.

When in use, the screw rod is Ф12~Ф20, the steel pipe is Ф48x3.5, and the thickness of the steel plate is not less than 6mm. The thread length of the screw is determined according to the thickness of the structural member, and a full-thread screw can also be used. During the construction of beams 7, columns 8, and shear wall concrete 9, pre-embed casings at the corresponding positions of scaffolding 10. Install wall parts after the concrete structure has a certain strength. The screw rod passes through the steel pipe on the scaffold, and the other end of the steel pipe is fastened with a bolt, and the steel pipe is tightly mounted on the outer wall of the building and connected with the scaffold by fasteners. When the scaffolding is dismantled, the connecting wall parts are loosened, and the connecting wall parts are recycled, which can be reused.
