Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a rebar positioning device for a prefabricated structure transfer layer. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. In prefabricated construction, prefabricated shear wall structures have gradually become a common structural form for residential buildings. However, because the underground structure is often a cast-in-place structure, there is a transfer layer between it and the above-ground prefabricated structure. The accuracy of the reinforcement positioning in the transfer layer affects the overall structural safety; therefore, the positioning of the reinforcement in the transfer layer is one of the key challenges in the construction process of prefabricated shear wall structures.

[0003] Currently, the most commonly used positioning device for transfer layers uses positioning steel plates. The principle is to drill holes in a 2-3mm thick steel plate according to the designed position and diameter of the wall reinforcement. These holes are used for positioning the reinforcement. Additionally, a 100mm hole is pre-drilled in the steel plate for concrete pouring. However, due to the wide variety of shear wall types and varying reinforcement positions in the transfer layer during actual construction, positioning steel plates are only suitable for shear walls of a fixed type. When the position of the transfer layer reinforcement changes due to different shear wall types, the existing positioning steel plate becomes unsuitable, requiring the fabrication of a new one, resulting in material waste and increased construction complexity.

[0004] Therefore, there is an urgent need to design a positioning device that can be adapted to the positioning and construction of different types of shear wall transfer layers. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated structural transfer layer reinforcement positioning device to solve the problems existing in the prior art and to adapt to the positioning construction of different types of shear wall transfer layers.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0021] This invention employs a positioning component for positioning. An adjustment device is slidably mounted on the positioning component along its length. A positioning tube fixed on the adjustment device is used to pass through and position the transfer layer reinforcement.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The purpose of this utility model is to provide a prefabricated structural transfer layer reinforcement positioning device to solve the problems existing in the prior art and to adapt to the positioning construction of different types of shear wall transfer layers.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Existing positioning devices for transition layers use positioning steel plates. Holes are drilled in the positioning steel plate according to the designed position and diameter of the wall reinforcement bars. These holes are used for positioning the reinforcement bars. Additionally, pre-drilled holes are made in the steel plate for concrete pouring. However, when the shear wall type changes, causing a shift in the reinforcement bar position, the holes in the positioning steel plate will no longer correspond to the changed reinforcement bars. This results in the positioning steel plate only being suitable for shear wall construction with a single reinforcement bar position, which is inconvenient. Furthermore, each type of shear wall requires a separately manufactured positioning steel plate, making construction cumbersome and wasting materials.

[0030] To solve the above-mentioned technical problems, this utility model provides a rebar positioning device for a prefabricated structure transfer layer, such as... Figure 1 and Figure 2 As shown, the system includes a positioning component 1, an adjusting device 2, and a positioning tube 3. This embodiment uses a combination of two positioning components 1 as an example. The positioning component 1 includes a positioning plate with an injection port 103 arranged along the length of the positioning component 1. The positioning plate replaces the original positioning steel plate. Above the injection port 103 on the positioning plate, the side of the adjusting device 2 is slidably connected to the positioning component 1. The adjusting device 2 can be fixed at a set position along the length of the positioning component 1, so that the position of the adjusting device 2 can be flexibly moved according to different types of shear walls, and the adjusting device 2 can be aligned with the actual rotation. The position of the replacement reinforcement is corresponding; by fixing the positioning tube 3 on the adjustment device 2 and arranging it perpendicular to the positioning plate, the replacement layer reinforcement can be passed through the positioning tube 3 to achieve the positioning of the replacement layer reinforcement. The outer and inner walls of the positioning tube 3 are provided with a galvanized layer to prevent corrosion of the positioning tube 3. This invention allows the adjustment device 2 and the positioning tube 3 to be moved according to the location of the replacement layer reinforcement of different types of shear walls. This makes the device adaptable to the positioning of shear walls with different replacement layer reinforcement positions, eliminating the need to make new positioning steel plates, reducing material waste and construction complexity.

[0031] To facilitate the connection of the adjustment device 2, in one embodiment, the positioning component 1 is also designed with an adapter plate. In this embodiment, an adapter plate is vertically fixed to each of the two sides of the positioning component 1 along its length. The side of the adjustment device 2 is slidably connected to the adapter plate on the same side, making the movement of the adjustment device 2 more convenient. After moving to the set position, it can be fixed with the adapter plate on the corresponding side, making the fixing method more diverse and reliable. In one embodiment, a plurality of adapter holes 104 are evenly provided on the adapter plate, and the plurality of adapter holes 104 are arranged along the length of the positioning component 1. The side of the adjustment device 2 is provided with a through hole, which can be coaxially fixedly connected with the adapter hole 104 at the set position. After the adjustment device 2 moves to the required position, its through hole is coaxially arranged with the adapter hole 104 at this position, and then fixed by bolts 4, screws, or rivets, etc., to achieve the fixing of the adjustment device 2.

[0032] The fixing method of the adjusting device 2 is not limited. In another embodiment, the side of the adjusting device 2 and the adapter plate can be fixed by a clamping device. For example, an open clamp can be used to clamp and fix the side of the adjusting device 2 and the adapter plate, which can also achieve a detachable connection between the adjusting device 2 and the positioning plate.

[0033] When the wall length is too large, this embodiment can also connect two or more positioning components 1 end to end in sequence to adapt to walls of different lengths. To achieve this function, a fixing device is designed in this embodiment. The fixing device uses bolts 4. The overall width of the positioning component 1 near one end is smaller than the overall width of the positioning component 1 near the other end. Thus, the narrower end of the positioning component 1 can be inserted into the wider end of another positioning component 1. Then, the adapter holes 104 on the adapter plate of the overlapping part of the two positioning components 1 are aligned and fixedly connected with bolts 4. Thus, one end of the positioning component 1 can be fixedly connected to one end of another positioning component 1, so that the connected structure can be adapted to walls of different lengths.

[0034] In one embodiment, the adjusting device 2 is in the form of a U-shaped plate structure. The two sides of the adjusting device 2 are fixedly connected by an adjusting plate, and the adjusting plate is arranged perpendicularly to the side of the adjusting device 2. The positioning tube 3 is fixedly connected to the adjusting plate, and one end of the positioning tube 3 passes through the adjusting plate, so that one end of the reinforcing bar can be inserted into the positioning tube 3.

[0035] For ease of manufacture, in one embodiment, the positioning component 1 is made of a connecting plate 102 and two symmetrically arranged angle steels 101. The angle steels 101 are 1m long and 50mm wide. Figure 1For example, when angle steel 101 is placed on the ground, the side parallel to the ground is the horizontal side, and the side perpendicular to the ground is the vertical side. The vertical side of angle steel 101 forms a transition plate, and there are two transition plates. One end of the horizontal side of angle steel 101 is fixedly connected to one end of the horizontal side of another angle steel 101 using a first 50mm thick connecting plate 102, and the other end of the horizontal side of angle steel 101 is fixedly connected to the other end of the horizontal side of another angle steel 101 using a second 50mm thick connecting plate 102, so that the distance between the two angle steels 101 is 200mm. The area enclosed by the horizontal sides of the two angle steels 101 and the two connecting plates 102 forms a grouting port 103. On the vertical side of angle steel 101, a transition hole 104 with an inner diameter of 14mm is opened at every 50mm interval. In this embodiment, the adjustment device 2 is made of 3mm thick steel plate. The width between the two sides of the adjustment device 2 is 204mm, which allows it to be snapped onto the positioning component 1. A through hole with an inner diameter of 14mm is opened at the center of the side of the adjustment device 2. Bolts 4 are used to fix the through hole to the corresponding transition hole 104 on the angle steel 101. Positioning tubes 3 with diameters of 14mm, 16mm, 18mm, 20mm, or 22mm are welded onto the adjustment device 2 according to the different diameters of the reinforcing bars. Two positioning tubes 3 are provided on each adjustment device 2, and the center distance between the two positioning tubes 3 is determined according to the design protective layer thickness of the reinforcing bars on site.

[0036] This invention maintains high stability during construction, preventing deformation or displacement, thus ensuring the quality and safety of the transfer layer reinforcement construction. Furthermore, this invention can be freely combined according to different shear wall lengths, and the position of the adjusting device 2 on the positioning component 1 can be adjusted to accommodate different vertical reinforcement spacings. This results in a high turnover rate for the device, allowing for multiple reuses and achieving material and cost savings.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
