Description

Technical Field

[0001] This utility model relates to the technical field of scaffolding connection devices, specifically to a scaffolding external wall connection device. Background Technology

[0002] As the construction industry continues to raise its requirements for building quality, construction efficiency, and green environmental protection, the requirements for building safety and construction quality during the construction process are increasing year by year.

[0003] However, the traditional method of setting up wall ties for external scaffolding, which is commonly used in cast-in-place construction, faces significant challenges in current building exterior wall construction. After the concrete is poured using formwork, through-holes are required on the smooth wall surface to facilitate post-installation anchoring, resulting in an inability to effectively connect the external scaffolding system with the main building structure. However, the method of drilling holes to install expansion bolts affects the overall reliability of the building structure. For thinner walls, the structural defects caused by this method not only reduce the overall stability of the scaffolding system but may also lead to major safety hazards such as scaffolding overturning and construction platform displacement during construction.

[0004] To address the aforementioned issues and ensure an effective connection between the external scaffolding system and the main building structure, we propose a scaffolding external wall ties device. Utility Model Content

[0033] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Please see Figures 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0035] In this embodiment, the scaffolding external wall ties are designed to provide a horizontal foundation. A cantilevered horizontal frame 6 is horizontally installed on the exterior facade of the vertical wall 3 using pre-embedded bolts 7. To improve stability and increase the load-bearing capacity of the cantilevered horizontal frame 6 on the scaffolding 8, see reference [reference needed]. Figure 1 Due to the positional relationship, a diagonal tie rod 5 is installed between the cantilevered horizontal frame 6 and the vertical wall 3. The upper diagonal tie rod 5 is also fixed to the vertical wall 3 by pre-embedded bolts 7.

[0036] To avoid the problem of drilling holes for fixing after the concrete has been cast, this embodiment pre-embeds wall-connecting components during the casting of the vertical wall 3, such as... Figures 1-3The structure shown first involves erecting a formwork for the vertical wall 3 and laying a steel reinforcement skeleton inside. During this process, the wall tie components are pre-embedded in the formwork, with both ends exposed. After the concrete is poured, the concrete fully encapsulates the wall tie components and solidifies, improving the pull-out resistance. After the concrete has solidified, the formwork is removed, and the wall tie components can form a reliable connection with the wall. At the same time, the exposed ends on the outside are connected to the scaffolding 8, so that the scaffolding 8 and the wall remain relatively fixed.

[0037] Specifically, in this embodiment, the wall-connecting assembly includes a pre-embedded fastening rod 1 and a pre-embedded connecting rod 2, which are horizontally installed within the vertical wall 3 and detachably connected, such as... Figures 2-4 The structure shown has a second internal threaded hole 102 and a first internal threaded hole 101 at both ends of the pre-embedded fastening rod 1, while the pre-embedded connecting rod 2 has an external threaded rod 21 and a third internal threaded hole 201 at both ends. The two are connected by the external threaded rod 21 being threaded into the second internal threaded hole 102.

[0038] To improve the tightness of the sealed connection, this embodiment, for example Figure 2 and Figure 3 The structure shown includes a pre-embedded connecting rod 2 with a cylindrical sleeve 22 having a diameter larger than the column body. The cylindrical sleeve 22 has a hollow cavity 202 corresponding to the pre-embedded fastening rod 1. The inner end of the pre-embedded fastening rod 1 has a protrusion 11 on its outer surface. The threaded connection process causes the protrusion 11 to... Figure 2 As shown in the positional relationship, it can be inserted into the hollow cavity 202 to form a sealed connection structure. At the same time, the protruding structure of the cylindrical sleeve 22 can increase the force-bearing area and cross-sectional area, thereby improving the tensile strength.

[0039] To improve the overall integrity between the device and the vertical wall 3, and further enhance the tensile strength, this embodiment, for example... Figure 3 and Figure 4 As shown in the structure, in this embodiment, a plate block 12 is coaxially connected to the pre-embedded fastening rod 1. The plate block 12 has four insertion holes 121 distributed along the axis for inserting reinforcing bars. That is, during the installation of the vertical wall 3 template and the arrangement of the reinforcing mesh, the horizontal reinforcing bars can be inserted into the insertion holes 121 and tied together with the reinforcing bars to further strengthen the anchoring effect, thereby further improving the structural reliability after pouring. At the same time, on the inner side, the pre-embedded fastening rod 1 is fixedly connected to a frustum block 13, which can increase the force-bearing area and prevent it from being pulled outward.

[0040] Considering the issue of thin walls and concerns about potential damage due to excessive localized stress, this implementation example... Figure 1 In terms of position, a diagonal brace 4 is installed between the horizontal wall 9 inside the vertical wall 3 and the first internal threaded hole 101. At the same time, a diagonal brace 4 is also connected between the vertical wall 3 and the horizontal wall 9 to improve the stability of the connection.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
