Pre-embedded construction structure of pulling foot

Abstract

The utility model discloses a pre-embedded construction structure of a pull foot. The pre-embedded construction structure comprises a formwork, a connecting piece and a connecting piece, wherein a space is formed by the formwork for containing a building body structure; the building body structure is arranged in the template; pipe bodies are pre-buried in the building body structure, and the multiple pipe bodies are arranged in the building body structure at intervals; the two ends of the pipe body are sealed and blocked and flush with the two side edges of the building structure to make close contact with a formwork. The sealing plates and the plugging covers at the two ends of the pipe body are in close contact with the formworks, when vibration is generated by pouring concrete vibration, the sealing plates and the plugging covers are in close contact with the formworks to ensure that concrete cannot flow into the pipe body, and the situation that the concrete is solidified on the inner face of the end of the pipe body to form a solidified plugging body is avoided; the problem that the later penetration smoothness of the through-wall piece is affected due to the fact that the interior of the pipe body is not smooth when the solidified plug body is cleaned is solved.

Description

Technical Field

[0001] The utility model relates to a pre-embedded construction structure of a pull foot, belonging to the technical field of building construction. Background Technique

[0002] When a tower crane or a lift is installed on the side of a high-rise building, a stressed pull foot is required for tie-in stress. For the convenience of construction, the wall-piercing members composed of bolts on the positioning panel need to be detachably penetrated through the building structure (see Chinese Patent Publication No. CN113666279B).

[0003] In order to form a through hole in the building structure for the wall-piercing member to penetrate, a pipe body needs to be pre-embedded in the building structure to form a through hole. The prior art is to directly pre-embed the pipe body 2 in the building structure 1. Although the pipe body 2 can form a through hole for the wall-piercing member to penetrate, during formwork support, there will be an interval gap between the formwork 3 and the end of the pipe body 2 due to the vibration of the concrete during pouring, and the concrete will flow in. After the concrete solidifies on the inner surface of the end of the pipe body 2, a solidified plug body 21 is formed. When the solidified plug body 21 is cleaned, the inner surface of the pipe body is not smooth, which affects the smoothness of the subsequent penetration of the wall-piercing member. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a pre-embedded construction structure of a pull foot.

[0005] The utility model is achieved through the following technical solutions.

[0006] A pre-embedded construction structure of a pull foot provided by the utility model includes:

[0007] A formwork that forms a space for accommodating the building structure;

[0008] The building structure is inside the formwork;

[0009] A pipe body is pre-embedded in the building structure, and the pipe bodies are spaced in the building structure;

[0010] Both ends of the pipe body are sealed and blocked and are flush with both sides of the building structure to closely contact the formwork.

[0011] The formwork is a wooden formwork or a steel formwork.

[0012] The building structure is composed of reinforced concrete pouring and solidification.

[0013] The pipe body is a steel pipe or an iron pipe.

[0014] It also includes a lift on the side of the building structure.

[0015] Sealing plates are fixed at the ends of multiple pipe bodies far away from the lift, and the sealing plates are hermetically and fixedly connected with the multiple pipe bodies; the ends of the pipe bodies close to the lift are blocked with plugging covers.

[0016] The plugging cover is composed of a plastic winding or a rubber cover; the closing plate is made of a steel plate or a rigid plastic plate.

[0017] The beneficial effects of the utility model are as follows: the closing plates and the plugging covers at both ends of the pipe body are in close contact with the formwork. When the concrete is vibrated during pouring, the closing plates and the plugging covers being in close contact with the formwork ensure that the concrete will not flow into the pipe body, avoiding the occurrence of a solidified plugging body formed after the concrete solidifies on the inner surface of the pipe body end, and solving the problem that the inner surface of the pipe body is not smooth during the cleaning of the solidified plugging body, which affects the smooth penetration of the wall-piercing parts in the later stage.

[0023] The technical solution of the present utility model will be further described below, but the scope of protection is not limited thereto.

[0024] As Figures 1 to 3 shown.

[0025] An embedded construction structure of a pull foot of the present application includes:

[0026] A formwork 3 composed of a wooden formwork or a steel formwork, and the formwork 3 forms a space where steel bars are bundled and concrete is poured and solidified to form a building structure 1, and the building structure 1 is inside the formwork 3.

[0027] A pipe body 2 is embedded in the building structure 1, and the pipe body 2 is made of a metal pipe, such as a steel pipe or an iron pipe, etc. The pipe body 2 is multiple and spaced in the building structure 1.

[0028] Closing plates 4 are fixed at the ends of multiple pipe bodies 2 away from the lift ladder 5, and the closing plates 4 are welded and sealed and fixedly connected to the multiple pipe bodies 2. The closing plates 4 seal the ends of the pipe bodies 2 and position and limit the distance between the multiple pipe bodies 2. The closing plate 4 is a rigid plate body, such as a steel plate or a rigid plastic plate, etc.

[0029] The end of the pipe body 2 close to the lift 5 is blocked by a blocking cover 6, and the blocking cover 6 is formed in the form of plastic winding or a rubber cover, etc. The two ends of the pipe body 2 corresponding to the closing plate 4 and the blocking cover 6 are flush with the side of the building structure 1 and are in close contact with the formwork 3.

[0030] After the formwork 3 is erected, the steel bars are tied. The blocking cover 6 is used to block the ends of multiple pipe bodies 2, and then the multiple pipe bodies 2 are placed into the formwork 3 through the closing plate 4. The closing plate 4 is tied or welded to the steel bars in the formwork 3. The closing plate 4 and the blocking cover 6 at both ends of the pipe body 2 are in close contact with the formwork 3. When the concrete is vibrated during pouring, the closing plate 4 and the blocking cover 6 are in close contact with the formwork 3 to ensure that the concrete will not flow into the pipe body 2, avoiding the situation where a solidified blocking body 21 is formed after the concrete solidifies on the inner surface of the end of the pipe body 2. When the concrete solidifies to form the building structure 1, the closing plate 4 and the blocking cover 6 at both ends of the pipe body 2 are flush with the building structure 1. The closing plate 4 is knocked off and the blocking cover 6 is pushed down. When the pipe body 2 is cleaned, the inside is smooth, ensuring that the wall-piercing member can pass through smoothly, solving the problem that the inside of the pipe body is not smooth during the cleaning of the solidified blocking body 21, which affects the smoothness of the later penetration of the wall-piercing member.
