Description

Hanging basket finish-rolled rebar rear anchor embedded parts

【Technical field】

The utility model relates to the field of construction, in particular to a pre-embedded part of a rear anchor which is made of finish-rolled screw steel during the construction of a hanging basket.

【Background technique】

During the construction of buildings, various construction equipment are used for construction. Among them, the hanging basket is the main equipment in the cantilever construction. According to the structural form, it can be divided into four types: truss type, cable-stayed type, steel type and mixed type. The hanging basket itself has the characteristics of light weight, simple structure, firm and stable, easy to move forward and assemble and disassemble, strong reusability, small deformation after stress, etc., and the space under the hanging basket is sufficient, which can provide large construction work surface, which is beneficial to the construction operation of steel formwork.

Hanging basket construction has become a preferred construction scheme during construction, and the safety factor of the anchor behind the hanging basket has also become an important link that must be considered in the construction design, which is related to whether the safety and stability of the hanging basket walking construction meet the construction requirements .

The rear anchor of the existing hanging basket is generally a vertical reserved hole embedded in the web of the box girder, and the anchoring effect is achieved by fixing the fine-rolled rebar under the bottom plate of the box girder. This method requires a long precision in the high web. Rolling rebar materials, and requiring workers to operate and anchor under the bottom plate of the box girder, is more dangerous, not only time-consuming and material-consuming, but also difficult to operate.

【Content of invention】

Aiming at the above problems, the utility model proposes a material- and manpower-saving, simple and effective operation mode, and a high-safety embedded part for the rear anchor of the hanging basket.

The utility model relates to the pre-embedded part of the rear anchor of the hanging basket finish-rolled rebar, the pre-embedded part includes a finish-rolled rebar connector, a steel plate and a hollow tube, and the finish-rolled rebar connector is welded together through the steel plate and the hollow tube , There is a center hole in the middle of the steel plate, the size of the center hole is adapted to the inner diameter of the hollow tube, and the end of the finish-rolled threaded steel connector facing the hollow tube is suitable for matching with the threaded rod.

The outer diameter of the steel plate is larger than the outer diameter of the hollow tube.

The hollow tube is a hollow steel tube.

The length of this hollow pipe, when keeping allowing it to embed in concrete, exceeds 15cm of concrete surface.

The utility model adopts the hollow pipe as the pre-embedded pipe, and the precision-rolled threaded steel connector is connected with the threaded rod, and the whole hollow pipe and the steel plate are pre-embedded in the concrete as the pre-embedded part, which completes the role of the anchor behind the hanging basket and reduces the operating cost. Difficulty, saving material and labor costs, and improving the safety factor of hanging basket operations.

【Description of drawings】

Fig. 1 is the schematic diagram of the structure of the embedded part of the rear anchor of the hanging basket of the utility model after finish-rolling rebar;

Among them: 10. Precision-rolled rebar connector; 20. Steel plate; 21. Center hole; 30. Hollow tube.

【Detailed ways】

The following will describe in detail the finished anchor embedded part of the utility model in combination with the accompanying drawings and embodiments.

Please refer to FIG. 1 , which shows a finished anchor embedded part of a hanging basket finished rolled rebar, which includes a finished rolled rebar connector 10 , a steel plate 20 and a hollow pipe 30 . Wherein the finish-rolled threaded steel connector 10 is used to connect with the threaded rod, and the two are screwed together by threads.

The finish-rolled threaded steel connector 10 is welded together by a steel plate 20 and a hollow tube 30. There is a circular center hole 21 in the middle of the steel plate 20, and the size of the circular center hole 21 is adapted to the inner diameter of the hollow tube 30. One end of the device 10 facing the hollow tube 30 is suitable for fitting with a threaded rod.

The hollow pipe 30 is a hollow steel pipe, and the length of the hollow pipe 30 exceeds the concrete surface by 15cm when it is embedded in the concrete. When the embedded part is embedded in concrete, the air steel pipe is a certain distance above the concrete, so that the subsequent construction can identify the position of the embedded part.

A steel plate 20 with an outer diameter much larger than the outer diameter of the hollow pipe 30 is added between the hollow steel pipe and the connector by welding a precision-rolled threaded steel connector 10 and a section of hollow steel pipe. The hollow pipe 30 is pre-embedded vertically in the web of the box girder, and the pre-embedded quantity is set according to the calculation requirements. After the pouring is completed, the hollow pipe 30 is firmly embedded in the concrete structure, and the rear anchor is connected with the main longitudinal beam of the hanging basket through the embedded part to play the role of the rear anchor of the hanging basket.

When in use, pass the finish-rolled threaded rod through the hollow tube 30 and connect it with the finish-rolled threaded steel connector 10, and fix the hanging basket longitudinal beam on it to play the role of rear anchor. The hollow tube 30 is used as the finish-rolled threaded rod to pass through For the pre-embedded pipe, the steel plate 20 is larger than the outer diameter of the hollow pipe, thereby improving the pull-out resistance of the pre-embedded part in concrete.

The above description is only the preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as above with the preferred embodiment, it is not used to limit the utility model.
