Description

Technical Field

[0001] This utility model relates to the field of multi-purpose wall tie structure technology, specifically a pipe pre-embedded component that can be used as a wall tie. Background Technology

[0002] In most cast-in-place structure constructions, pipe openings often need to be achieved through secondary openings later. Secondary openings can disrupt the continuity of the concrete structure, weaken the integrity of the component sections, and lead to changes in the local stress distribution of the structure. Especially for cast-in-place structures with seismic requirements, this may reduce their seismic performance. Furthermore, improper handling of the openings can easily become a water leakage hazard. Improper operation (such as improper use of tools causing damage to the concrete around the opening, or failure to carry out reasonable reinforcement) can further aggravate the adverse effects on the structure.

[0003] Traditional pipe embedding methods not only require a large number of embedded pipes, but also the embedded pipes are prone to displacement during construction due to factors such as concrete pouring, which increases construction costs and the difficulty of later adjustments. In addition, scaffolding wall ties and pipe embedding are mostly set up independently, resulting in low material utilization and overall construction efficiency that needs to be improved. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a pipe pre-embedded component that can be used as a wall connection component, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe pre-embedded component that can be used as a wall tie, comprising a steel plate and a steel pipe, wherein the steel plate and the steel pipe are spot-welded together by E-type welding rods to form an integral component, which has the functions of both scaffolding component wall tie and pipe pre-embedded component, wherein the inner diameter and length of the steel pipe can be selected as needed according to the size of the opening on site and the width of the pre-embedded wall, and the steel plate has a size of 250mm×250mm×20mm;

[0006] The welding position of the steel pipe is determined according to the width of the wall. The reserved length of the steel pipe on the outside side extends beyond the wall surface and meets the relevant specifications and calculation requirements of the scaffold wall tie, so as to achieve a stable connection with the external scaffold and bear the load transmitted by the scaffold components.

[0007] When the component is used as a wall tie for scaffolding, it is welded to the wall in the center. The overall stability is enhanced by spot welding with the steel cage, reducing the positional displacement caused by concrete pouring and meeting the connection and fixing requirements between the scaffolding component and the wall.

[0008] When the wall thickness is 200mm, the welding length between the steel pipe and the steel plate on the indoor side is 100mm, and the welding length between the steel pipe and the steel plate on the outdoor side is greater than 100mm. This ensures the connection strength of the scaffolding components when they are connected to the wall, and also reserves a reasonable length for the subsequent use of pipes.

[0009] After the component completes its function as a wall tie for scaffolding, the steel pipe can be cut and used as a pipe such as an air conditioning duct, realizing the functional conversion from a wall tie to a pipe and reducing the amount of separately pre-embedded pipes.

[0010] By adopting the above technical solution, steel plates and steel pipes are spot-welded together using E43 welding rods to form an integral component. This component can be used as a scaffolding wall tie and also as a pre-embedded pipe structure, achieving "one material for two uses." This reduces material waste and construction procedures, and improves material utilization. The spot-welded connection between the component and the wall reinforcement cage effectively reduces positional displacement during concrete pouring, avoiding the problem of easy displacement of traditional pre-embedded pipes. The rubber plug on the inner side of the steel pipe can prevent pipe blockage during pouring, ensuring the functionality of the pipes later. After completing the wall tie function, it can be used as an air conditioning duct or other pipes by cutting, without the need for secondary drilling, avoiding damage to the integrity of the concrete structure, and balancing construction safety and structural stability. It is suitable for various cast-in-place structure projects.

[0011] Furthermore, a rubber plug is installed inside the steel pipe on the indoor side.

[0012] By adopting the above technical solution, rubber plugs are used to seal the openings of steel pipes, preventing concrete blockage and ensuring the structural integrity when used as scaffolding wall ties, while also providing a smooth passage for subsequent use as pipelines.

[0013] In summary, this utility model has the following beneficial effects: This utility model forms an integral component by spot welding steel plates and steel pipes with E43 welding rods. It can be used as a scaffolding wall tie and also as a pipe pre-embedded structure, achieving "one material for two uses," reducing material waste and construction procedures, and improving material utilization. The spot welding connection between the component and the wall reinforcement cage effectively reduces positional displacement during concrete pouring, avoiding the problem of easy displacement of traditional pre-embedded pipes. The rubber plug on the inner side of the steel pipe prevents pipe blockage during pouring, ensuring the later function of the pipe. After completing the wall connection function, it can be used as an air conditioning duct or other pipe by cutting, without the need for secondary drilling, avoiding damage to the integrity of the concrete structure, balancing construction safety and structural stability, and is suitable for various cast-in-place structure projects.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Example

[0022] like Figure 1-4 As shown, the embedded component provided in this embodiment consists of a steel plate 1 and a steel pipe 2. Through integrated design, it achieves the dual functions of scaffolding wall connection and pipe embedding. The specific structure is as follows:

[0023] Steel plate 1: A 250mm×250mm×20mm Q235 steel plate with rust prevention treatment is used as the connection base between the component and wall 4 to enhance the overall stability;

[0024] Steel pipe 2: Select the inner diameter and length according to the width of wall 4 and the pipe requirements. Connect it to steel plate 1 by spot welding with E43 welding rod to form an integral component. Steel pipe 2 is divided into two sections, indoor side and outdoor side. The welding position is determined according to the wall thickness to ensure that the reserved length on the outdoor side meets the specifications for scaffold wall ties.

[0025] Rubber plug 3: Installed on the inner side of the steel pipe 2, made of aging-resistant rubber, used to seal the pipe opening and prevent the steel pipe 2 from being blocked during concrete pouring;

[0026] Connection node: When the component is embedded in the wall 4 in the center, it is spot welded to the steel cage 5 inside the wall to further fix the position and reduce the offset during pouring;

[0027] Specific implementation steps

[0028] Component prefabrication and selection

[0029] The dimensions of steel pipe 2 are determined based on the thickness of wall 4. The welding length between the indoor steel pipe and steel plate 1 is 100mm, and the welding length on the outdoor side is 120mm, to ensure that the load transfer requirements of the scaffold wall tie are met and the pull-out force is ≥10kN.

[0030] Using E43 welding rods, steel pipe 2 is vertically spot-welded to the center of steel plate 1, with no less than 4 welding points and each weld length ≥ 50mm, to ensure the connection strength between the two.

[0031] Pre-embedded installation

[0032] During the wall reinforcement binding stage, the precast components are placed in the center at the designed position, with the outdoor side of the steel pipe facing the scaffold and the indoor end sealed with a rubber plug 3.

[0033] The steel plate 1 is spot-welded to the wall reinforcement cage 5, with a weld spacing of ≤150mm, to prevent the component from shifting during concrete pouring and to ensure that the pre-embedded position deviation is ≤5mm.

[0034] Used as a wall tie for scaffolding

[0035] After the concrete of wall 4 has been cured to the design strength, the temporary protection on the outside of steel pipe 2 is removed. The wall ties of scaffolding component 6 are welded or bolted to steel pipe 2. The steel pipe is used to transfer the horizontal and vertical forces of scaffolding component 6. After the connection is completed, the verticality of the component and scaffolding component 6 is checked. The deviation is ≤1° to ensure the stability of the load transfer path.

[0036] Used as a pipe embedding component

[0037] After the scaffolding component 6 is dismantled, the excess part of the steel pipe 2 that extends beyond the wall on the outside is cut off, leaving it flush with the wall, and the rubber plug 3 on the inside is removed.

[0038] The inside of steel pipe 2 is cleaned and rusted, and it can be used as a pre-embedded channel for air conditioning ducts or other pipelines as needed, realizing the conversion from wall tie to functional pipeline;

[0039] In summary, steel plate 1 increases the contact area between the component and wall 4, and with spot welding to the reinforcing cage 5, it effectively resists the impact force during concrete pouring, keeping the component's positional offset within 3mm. Steel pipe 2 serves as a force transmission carrier, meeting the mechanical requirements of scaffolding wall connection and reserving a channel for future pipeline use. Rubber plug 3 tightly seals steel pipe 2 during the pre-embedding stage, preventing concrete slurry from seeping in and causing pipeline blockage, ensuring that no secondary unblocking is needed during later functional conversion, thus reducing construction costs.

[0040] This embodiment solves the drawbacks of traditional separate installation of pipe pre-embedding and scaffolding wall ties through a "one material, two uses" design. The component has both wall ties and pre-embedding functions, reducing material usage and construction procedures. The fixed connection with the steel cage 5 reduces the risk of pre-embedding displacement and avoids damage to the structure caused by secondary openings later. The function conversion is convenient and it is suitable for cast-in-place structure projects such as residential and commercial buildings. While ensuring construction safety, it improves material utilization and construction efficiency.
