Description

Technical Field

[0001] The invention belongs to the technical field of scaffold connection, and in particular relates to an embedded part, an embedded tool, an embedded fixing structure and an embedded construction method thereof for scaffold connection. Background Art

[0002] Generally speaking, traditional wall ties are constructed using the embedded steel pipe method, leaving large holes in the exterior wall, which can easily damage the exterior wall concrete. Sealing the holes with scaffolding for decoration and repairing leakage after completion are both difficult. In addition, the embedded steel pipes left in the exterior wall need to be cut before they can be removed, and some components remain in the wall and cannot be removed, requiring concrete pouring, which creates quality and safety risks and material waste.

[0003] Chinese Patent Publication No. CN210508338U discloses a reusable pre-embedded assembled wall connection, comprising an embedded part and an external connection part connected to the embedded part. The embedded part is a conical structure with a conical thread on the outer wall of the embedded part, an internal thread inside the embedded part, and an external thread that matches the internal thread at one end of the external connection part. However, the patent uses an L-shaped external wall connection part without explaining how to connect it to the scaffolding uprights. Moreover, the conical design is larger on the outside and smaller on the inside, making it easy to fall off, which can easily damage the wall and embedded part when removed. According to the structure illustrated in the patent drawings, the patent does not explain the relative position of the embedded part and the mold, nor does it explain how to fix it. The patent plug is too simple and cannot completely prevent cement slurry from entering the internal threaded hole.

[0004] Chinese patent publication number CN208502220U discloses a pre-embedded nut wall connection, which includes a straight-line connector, one end of which is connected to an embedded part located in the building concrete structure; the other end of the straight-line connector is connected to one end of a connecting rod, and the other end of the connecting rod is connected to an external frame upright via a clamping member. The straight-line connector in the middle of the embedded parts in this patent is a flexible connection. According to relevant safety regulations, flexible connections have a low safety factor, poor torsional resistance of the frame, and a limited scope of use. According to the description in the patent specification, the embedded parts are placed first, and it fails to effectively explain how to avoid damaging the embedded parts when placing the bottom reinforcement of the steel beam in the subsequent process. In actual construction, it is also impossible to install the steel beam later. According to the level of disclosure of the patent, it does not explain how to effectively fix the embedded parts.

[0005] Based on the above content, we propose an embedded part, embedded tool, embedded fixing structure and embedded construction method for scaffolding connection. Summary of the Invention

DETAILED DESCRIPTION

[0047] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0048] like Figure 1 and Figure 4 As shown, an embedded part for scaffolding connection includes an embedded fixed part 11 and a movable part 12. The embedded fixed part 11 includes an integrally connected hexagonal head 111 and a column 114. The outer wall of the column 114 is corrugated to strengthen the bond with the concrete. The head 111 has a diameter of 50 mm and a length of 10 mm. The column 114 is 100 mm long and has a diameter of 25 mm. The interior of the column 114 is provided with a threaded groove 112 opening toward the tail end. The outer wall of the head 111 is provided with a hook 113 for connecting to a support member. The movable part 12 is connected to the embedded fixed part 11 by inserting into the threaded groove 112.

[0049] Among them, when pre-embedded, the pre-embedded fixed part is specifically the fixed part 11, and the fixed part 11 is made of steel material or hard plastic material. The movable part is specifically the plug 121, and the plug 121 is made of soft plastic material. When the scaffolding is connected after pre-embedding, the movable part is specifically the scaffolding connecting piece 122, and the scaffolding connecting piece 122 and the pre-embedded fixed part 11 are made of steel material.

[0050] like Figure 5 As shown, the plug 121 includes an integrally formed plug cap 1211 and a plug column 1213. The plug cap 1211 has a diameter of 60 mm and a length of 10 mm. The plug column 1213 is threadedly connected to the thread groove 112. The plug column 1213 is 30 mm long. The gap between the outer wall of the plug column 1213 and the plug cap 1211 is a groove 1212. The depth and radius of the groove 1212 are both 5 mm. A tool groove 1214 is provided on the outer wall of the plug cap 1211. The tool groove 1214 can be a hexagonal groove, a slotted groove or a cross groove. After a tool is inserted into the tool groove 1214, the plug cap 1211 is rotated to facilitate the removal of the plug cap 1211.

[0051] like Figure 6As shown, the scaffolding connector 122 includes an integrally formed steel pipe portion 1221 and a connecting portion 1222.
