Description

TECHNICAL FIELD

[0001] The utility model relates to a ladder cage and concrete foundation locking structure and belongs to the technical field of bridge engineering construction. BACKGROUND

[0002] At present, bridge engineering construction involves a large number of high-altitude operations, thereby greatly increasing the demand for ladder cages, and how to achieve rapid locking between the ladder cage and the concrete foundation has been a problem plaguing construction units.

[0003] In the past, construction units have adopted the method of setting flanges on the lower four legs of the ladder cage to connect and fix the ladder cage and the concrete foundation by expanding bolts, which not only wastes operation time but also requires re-drilling expansion bolts every time the ladder cage is moved, thus requiring the purchase of a large number of expansion bolts, resulting in high costs, and the limited area of the concrete foundation and the limited position of the expansion bolts have low reusability. SUMMARY

[0004] The utility model aims at overcoming the deficiencies in the prior art and providing a ladder cage and concrete foundation locking structure that can achieve rapid locking of the ladder cage and the concrete foundation, saving ladder cage installation time and reducing construction costs.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] The utility model provides a ladder cage and concrete foundation locking structure, a reinforcing mesh is embedded in the concrete foundation, a plurality of reinforcing connecting bodies are arranged above the reinforcing mesh, a channel steel is arranged above the reinforcing connecting body, and the channel steel extends to the outside of the concrete foundation;

[0007] A first hole is arranged on the channel steel, a bolt is arranged in the first hole, the ladder cage is provided with a ladder cage leg, the ladder cage leg extends into the corresponding channel steel, and the part of the ladder cage leg extending into the channel steel is provided with a second threaded hole matched with the bolt, and the bolt can be arranged in the first hole and the second threaded hole to fix the channel steel and the ladder cage.

[0008] Further, the reinforcing connecting body and the channel steel are both U-shaped, the open end of the reinforcing connecting body is connected with the reinforcing mesh, and the open end of the reinforcing connecting body is connected with the open end of the channel steel at the opposite end.

[0009] Further, the first hole is arranged at the corresponding position of the two sides of the U-shaped channel steel.

[0010] Further, the surface of the concrete foundation is flush with the inner bottom surface of the channel steel.

[0011] Furthermore, the channel steel and the reinforcing bar connectors are all located at the four vertical azimuth angles of the concrete foundation, and the azimuth angle positions correspond to the ladder cage legs and are 55cm away from the edge of the concrete foundation.

[0012] Furthermore, each of the aforementioned azimuth angles has multiple steel reinforcement connectors, which are all vertically and equally spaced on the steel reinforcement mesh, with a spacing of 15cm.

[0013] Furthermore, the length of the first hole is 5 cm.

[0014] Furthermore, the length of the channel steel is 0.5m.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0016] This utility model utilizes channel steel instead of expansion bolts to connect stably with concrete. The bolts can fix the ladder cage legs to the channel steel, achieving rapid locking between the ladder cage and the concrete foundation, saving ladder cage installation time. Furthermore, after the concrete foundation is broken after the project is completed, the channel steel can be recycled and reused, resulting in a high reuse rate and saving construction costs.

[0017] The first hole of this utility model is a long hole, which facilitates the movement of the ladder cage and eliminates the need to repeatedly drive in expansion bolts, making it simple and quick. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0022] like Figure 1 As shown, this utility model embodiment provides a locking structure between a ladder cage and a concrete foundation. A steel mesh 7 is embedded in the concrete foundation, and steel connectors 8 are vertically arranged at four azimuth angles 55cm from the edge of the steel mesh 7, each spaced 15cm apart.

[0023] CombinationFigure 2 In this embodiment, the rebar connector 8 is U-shaped, with its open end connected to the rebar mesh 7 and its opposite end connected to the channel steel 6. The channel steel 6 is also U-shaped and 0.5m long. The opposite end of the channel steel 6 is welded to the opposite end of the rebar connector 8. However, this is not the only option. Any connection method other than welding that can fix the channel steel to the rebar connector 8 should be acceptable.

[0024] The channel steel 6 extends to the outside of the concrete foundation 1, and in this embodiment, the concrete foundation 1 is flush with the inner surface of the channel steel 6. A first hole 4 is provided at the center of both sides of the channel steel 6. The first hole 4 is an elongated hole with a length of 5cm. A bolt 3 is inserted into the first hole 4.

[0025] The ladder cage 2 is provided with ladder cage legs 201. The position of the ladder cage legs 201 corresponds to that of the channel steel 6, so that the ladder cage legs 201 can extend into the channel steel 6. The part of the ladder cage legs 201 that extends into the channel steel 6 is provided with a second threaded hole 5. The second threaded hole 5 is compatible with the bolt 3. The bolt 3 can be inserted into the first hole 4 and the second threaded hole 5 to fix the channel steel 6 and the ladder cage 2.

[0026] The installation principle of this utility model includes:

[0027] Select suitable positions on the steel mesh 7 pre-embedded in the concrete foundation 1, namely the four azimuth angles of the concrete foundation 1. Then, install multiple steel connectors 8 connected to the steel mesh 7 every 15cm, with the steel connectors 8 arranged vertically along the concrete foundation 1. Weld channel steel onto the steel connectors 8, and then pour concrete so that the concrete foundation 1 is flush with the bottom surface of the channel steel 6.

[0028] A first hole 4, 5cm long, is made at the center of both sides of the channel steel 6. A bolt 3 is inserted into the first hole 4. A second threaded hole 5, which is compatible with the bolt 3, is made on the ladder cage support leg 201. The bolt 3 is inserted into the first hole 4 and the second threaded hole 5 to fix the ladder cage to the concrete foundation 1.
