Description

Technical Field

[0001] The utility model relates to the technical field of industrial building construction, in particular to a connecting member of a scaffold. Background Technique

[0002] At present, during the construction of the connecting members of the external scaffold of multi-storey residential buildings, the height of the scaffold is less than 24 meters. Since the external walls of multi-storey residential buildings are load-bearing walls, holes will be reserved at the positions where the connecting members are set during the masonry of the external walls. If the reserved holes are too large, it will affect the safety of the overall load-bearing wall. When the connecting members are removed later, it may be difficult to remove the embedded vertical steel pipes because the steel pipes and fasteners are connected to the mortar. Only the horizontal crossbars can be cut first, and then the manpower can be slowly spent on cleaning and filling the holes. In addition, there may also be water leakage due to the large holes not being sealed properly, affecting the quality of the load-bearing wall.

[0003] In the prior art, the method of setting the connecting members is to embed short steel pipes in the cast-in-place concrete beams. After the concrete of the beams is poured, the embedded steel pipes exposed above the beams are connected to the vertical poles of the external scaffold through horizontal bars and fasteners. The labor cost is relatively high and it is easy to affect the quality during the masonry of multi-storey walls. The removal of the connecting members of the external scaffold later requires a lot of time, reducing the work efficiency and bringing inconvenience to the use of construction workers. Although there is also a method of using round steel as the material of the connecting members to reduce the holes of the connecting members on the surface of the cast-in-place concrete structure wall, the connection part between the round steel and the surface of the cast-in-place concrete structure wall is exposed for a long time and lacks waterproof measures, and there is still a situation of inward leakage of the external wall. Content of the Utility Model

[0004] In view of this, the connecting member of the scaffold provided by the utility model can effectively reduce the loss of steel pipe fasteners and the risk of external wall leakage by setting a connecting piece and a water stop piece at the embedded part near the surface of the cast-in-place concrete structure external wall, without the need for later hole filling, and can speed up the removal progress of the external scaffold.

[0005] The connecting member of the scaffold provided by the utility model includes an external scaffold crossbar arranged between two external scaffold vertical poles close to the cast-in-place concrete structure on the scaffold. A connecting piece is arranged between one end of the external scaffold crossbar facing the cast-in-place concrete structure and the cast-in-place concrete structure. The connecting piece includes an embedded part embedded in the cast-in-place concrete structure and a connecting part located outside the cast-in-place concrete structure and connected to the end of the external scaffold crossbar. A water stop piece for preventing external wall leakage is arranged at the embedded part near the surface of the cast-in-place concrete structure external wall.

[0006] Further, the embedded part includes a vertical rod vertically arranged in the cast-in-place concrete structure and a crossbar vertically arranged on the surface of the cast-in-place concrete structure external wall between the top of the vertical rod and the surface of the cast-in-place concrete structure external wall. The water stop piece is arranged at the position of the crossbar close to the surface of the cast-in-place concrete structure external wall.

[0007] Further, the connecting part is formed by extending the end of the cross bar located on the outer wall surface of the concrete-cast structure outward.

[0008] Further, the length of the vertical bar in the embedded part is ≥ 200 mm.

[0009] Further, the water stop is a water stop ring.

[0010] Further, double-sided fish-scale welding is used between the connecting part and the outer frame cross bar, and the welding length is ≥ 200 mm.

[0011] The beneficial effects of the present utility model are as follows: The scaffolding connecting member provided by the present utility model has no holes left by traditional connecting members, eliminating the later hole repair cost, saving steel pipe and fastener materials, accelerating the removal progress of the outer frame, and reducing the leakage risk.

[0015] As shown in the figure, the scaffolding connecting member provided by the present utility model includes an outer frame cross bar 2 arranged between two outer frame vertical bars 1 on the scaffolding close to the cast-in-place concrete structure 3. A connecting member 4 is arranged between the end of the outer frame cross bar 2 facing the cast-in-place concrete structure 3 and the cast-in-place concrete structure 3. The connecting member 4 includes an embedded part embedded in the cast-in-place concrete structure and a connecting part located outside the cast-in-place concrete structure and connected to the end of the outer frame cross bar. The embedded part is provided with a water stop for preventing the outer wall from leaking at a position close to the outer wall surface of the cast-in-place concrete structure; among them, the connecting member 4 is formed into an L-shaped structure after processing a round steel with a diameter greater than 20 mm. Using round steel as the connecting member can effectively avoid large holes left by the round steel on the surface of the cast-in-place concrete structure wall. When the scaffolding is demolished, it can be cut along the edge of the cast-in-place concrete structure 3. At this time, there are no holes left by traditional connecting members on the surface of the cast-in-place concrete structure 3 wall, eliminating the later hole repair cost, saving steel pipe and fastener materials, and accelerating the removal progress of the outer frame; and by providing a water stop for preventing the outer wall from leaking at a position close to the outer wall surface of the cast-in-place concrete structure in the embedded part, it can prevent the outer wall from leaking inward after the connecting member located outside the cast-in-place concrete structure is cut off, reducing the leakage risk.

[0016] In this embodiment, the embedded part includes a vertical rod vertically arranged inside the cast-in-place concrete structure 3 and a horizontal rod vertically arranged between the top of the vertical rod and the outer wall surface of the cast-in-place concrete structure 3 perpendicular to the outer wall surface of the cast-in-place concrete structure 3. The water stop is arranged at a position of the horizontal rod close to the outer wall surface of the cast-in-place concrete structure 3; the connecting part is formed by extending outward from the end of the horizontal rod located on the outer wall surface of the cast-in-place concrete structure. Combined with Figure 1 As shown, the embedded part is an L-shaped structure embedded in the cast-in-place concrete structure 3, and the connecting part is formed by extending outward from the end of the horizontal rod located on the outer wall surface of the cast-in-place concrete structure.

[0017] In this embodiment, the length of the vertical rod in the embedded part is ≥200 mm; in order to ensure the firm connection between the connecting piece 4 and the cast-in-place concrete structure 3, the length of the vertical rod in the embedded part needs to be set ≥200 mm.

[0018] In this embodiment, the water stop is a water stop ring 5; the water stop includes a water stop ring, a water stop sheet or a water stop ring, etc., which is mainly used to extend the path of water seepage and greatly increase the seepage resistance to achieve the anti-seepage purpose. Compared with the water stop ring and the water stop sheet, the water stop ring has a better anti-seepage effect in the cast-in-place concrete structure 3.

[0019] In this embodiment, the connecting part and the outer frame horizontal bar 2 are welded by double-sided fish scale welding and the welding length is ≥200 mm; by setting the double-sided fish scale welding and the length of the welding section 9 ≥200 mm, the connection between the connecting piece 4 and the outer frame horizontal bar 2 can be effectively strengthened, and the overall connection strength of the scaffold can be ensured.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
