Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a bolt locking tool type wall connecting piece. Background Art

[0002] In the construction of high-rise buildings, the installation of scaffolding wall ties is the top priority to ensure the safety of the scaffolding. One end of the wall tie is connected to the steel pipe scaffolding, and the other end is tied to the building structure. It is the most important structural measure to ensure the safety of scaffolding operations. Traditional wall tie methods include steel pipe fasteners holding frame columns, steel pipe fasteners locking door and window openings, and reserved holes for steel pipes in the structural walls, or pre-embedded steel pipes in the structure and tied to the steel pipes with fasteners. These traditional methods are cumbersome in process, cumbersome in construction operations, and time-consuming and labor-intensive in post-processing.

[0003] At present, there are two types of mainstream wall ties on the market. One is to weld the tail plate at the end, open bolt holes in the tail plate, and fix it to the wall with bolts. The other end of the short rod is fixed to the scaffolding pole or crossbar with a buckle, such as the scaffolding wall tie recorded in the invention patent application with publication number CN106193574B. The other is the connection method of bolts through fasteners, which are fixed to the structure with bolts and connected to the steel pipe, such as the fastener-type wall tie recorded in the utility model patent with publication number CN217480780U.

[0004] Although the above two types of tool-type wall ties have simplified the construction process to a certain extent and reduced some labor intensity, their safety has yet to be verified. In the scaffolding calculation book, the calculation of these two types of tool-type wall ties is often based on the calculation of the bolt strength of the bolts fixed to the main structure, while ignoring the anti-slip strength verification of the fasteners. In fact, these two types of wall ties are subjected to force by the fixed bolts and fasteners working together. In addition to calculating the bolt strength, the anti-slip strength of the fasteners must also be calculated. When calculating the anti-slip strength verification of the wall tie fasteners, it is often found that in the commonly used two-step and three-span arrangement of wall ties, the anti-slip bearing capacity verification of a single fastener does not meet the requirements. The main reason is Because the national standard for the anti-slip bearing capacity of the fastener itself is 8KN, and the anti-slip reduction coefficient of the standard fastener is 0.9, the actual value is only 7.2KN. Since the fastener transmits loads by friction, the fastener locking bolt part is open. Its structural defects often cause bolt loosening under long-term stress, resulting in friction failure and instability of the wall connection, leading to safety risks or safety accidents. In daily construction, especially in windy weather, the external scaffolding frame often tilts outward, the facade of the frame is wavy, and other situations that affect construction safety occur. After on-site inspection, it will be found that the fasteners at the wall connection part have partial slippage or failure. According to the calculation requirements, in the case of a two-step three-span layout, if the single fastener verification fails, double fasteners or two-step two-span layouts are generally used; it is obviously difficult to install double fasteners on these two tool-type wall connections, so there is only a two-step two-span layout to ensure the safety of scaffolding construction, which also increases labor intensity and labor costs to a certain extent.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] The utility model provides a bolt locking tool-type wall connecting piece, which is used for connecting a scaffold 100 and a building outer wall 400.

Specifically, as Figure 1 As shown, the scaffold 100 includes two layers of vertical poles spaced apart from each other, the inner poles 102 close to the building outer wall 400 and the outer poles 104 away from the building outer wall 400, a small horizontal crossbar 103 is horizontally connected between the inner poles 102 and the outer poles 104, the small crossbar 103 is perpendicular to the building outer wall 400, and a large crossbar 101 horizontally and longitudinally arranged parallel to the building outer wall 400 is supported below the small crossbar 103, the large crossbar 101, the small crossbar 103, the inner poles 102, and the outer poles 104 are connected together to form the scaffold 100, because the inner poles 102 and the inner large crossbar 101 are close to the building outer wall 400 and are parallel to the building outer wall 400, the wall connecting parts are connected between the building outer wall 400 and the inner poles 102, and between the building outer wall 400 and the large crossbar 101, so that a stable connection can be formed.

[0036] The wall connecting parts in the prior art are usually connected to a small cross bar 103 perpendicular to the outer wall 400 of the building, or connected to the cross joint of the scaffolding 100; the connection method of forward pulling with the small cross bar 103 can achieve quick connection and disassembly, but due to the easy occurrence of forward slippage, the structural stability is poor; and the method of connecting with the cross joint of the scaffolding 100 has good structural stability, but requires fasteners with complex structures. The installation and disassembly of the fasteners are cumbersome, which greatly reduces the construction efficiency.

[0037] Based on the problems existing in the prior art, the wall connecting member of the utility model adopts a structure of vertically connecting the inner vertical rod 102 and the large horizontal rod 101, such as Figure 2 and Figure 3 As shown, the structural strength can be met, and at the same time the structure is simple and easy to disassemble and assemble, which can reduce labor intensity and construction costs to a certain extent.

Specifically, an anchor hole is opened on the building outer wall 400. After the tie screw 200 is inserted into the anchor hole, the inner gasket 206 and the outer gasket 205 are respectively placed on both sides of the building outer wall 400, and are respectively fastened by means of the inner locking nut 207 and the outer locking nut 204, so that the tie screw 200 is anchored in the building outer wall 400.

[0039] like Figure 6As shown, the scaffolding connection lock 300 includes a first lock 301 and a second lock 302 which are hinged on one side and bolted on the other side.
