TECHNICAL FIELD

[0001] The utility model relates to building scaffold technical field, concretely is a concrete building scaffold pre -buried connecting device. BACKGROUND

[0002] In the field of construction engineering, the construction of concrete buildings occupies an important position. Scaffold, as an indispensable temporary facility in construction, provides an operating platform for construction personnel, facilitating various types of construction work such as concrete pouring, wall building, decoration, etc. It not only ensures the safety of construction personnel, but also improves construction efficiency and quality. In the construction process of concrete buildings, it is necessary to firmly connect the scaffold to the main structure of the building to ensure the stability and safety of the scaffold. The traditional scaffold connection method usually adopts methods such as post-hole drilling and installation of expansion bolts on the concrete structure to realize the connection of the scaffold and the building. This method can meet the construction requirements to a certain extent and ensure the basic use function of the scaffold, but this connection structure may appear loose under different environmental conditions, for example, vibration and impact force may occur during hole drilling, which may cause cracks and looseness in the concrete structure, reducing the stability of the connection, and the existing installation method requires a series of operation steps such as hole drilling, hole cleaning, expansion bolt installation, etc., which is relatively cumbersome and may result in low installation efficiency. Therefore, we propose a concrete building scaffold pre-embedded connection device to solve the above problems. SUMMARY

[0024] Example 1

[0025] like Figures 1 to 3 As shown, the present invention provides a pre-embedded connection device for concrete building scaffolding, comprising:

[0026] Base 1;

[0027] Mounting component 4 is fixedly installed on the top of base 1;

[0028] The fixing component is installed at the bottom of the base 1. The fixing component includes a pre-embedded rod 2, which is fixedly installed at the bottom of the base 1. A limit ring 3 is fixedly installed at the bottom of the pre-embedded rod 2. Both the pre-embedded rod 2 and the limit ring 3 are pre-embedded in concrete.

The installation groove 5 and the connecting groove 6 are connected, which greatly improves the stability of the base 1. At the same time, the pre-embedded rod 2 and the limit ring 3 can improve the load-bearing capacity and durability by being pre-embedded in concrete.

[0029] The diameter of the mounting groove 5 is smaller than that of the connecting groove 6, providing a scale line for concrete pouring, while also allowing the connecting rod 14 to be installed in the mounting groove 5.

A fixing rod 8 is hinged to one side of the first connecting block 7, and the middle surface of the fixing rod 8 is provided with a thread. A first nut 9 is threaded onto the middle of the fixing rod 8. A collar 10 is provided above the mounting member 4, and second connecting blocks 11 are fixedly installed on both the left and right sides of the collar 10. A slot 12 is provided on the outer side of the second connecting block 11. The top of the fixing rod 8 is embedded in the slot 12. The first nut 9 is tightly attached to the bottom of the second connecting block 11. A connecting rod 14 is inserted into the inside of the mounting groove 5 and is embedded in the inside of the collar 10. The middle surface of the connecting rod 14 is provided with threads. A second nut 13 is provided above the collar 10 and is threaded onto the outside of the connecting rod 14.
