Technical Field
[0001] The present application relates to the technical field of wall column positioning, and in particular to a concrete wall reinforcement positioning device. Background Art
[0002] During the construction of concrete wall columns, it is necessary to adjust the steel bars and make vertical connections according to the construction requirements to ensure the connection position and quality of the steel bars.
[0003] After the steel bar connection is completed, the formwork must be installed. When installing the concrete wall column formwork, positioning bars are usually welded to fix the formwork to ensure that the steel bar protection layer meets the design and specification requirements.
[0004] At present, the widely used method is to re-weld the steel bars at the bottom of the wall column steel bars for positioning. This method is inefficient and difficult to operate. After the wall column concrete is formed, the wall column steel bars are often offset, and the wall column concrete is misaligned and overflowed due to loose template joints and poor verticality. Summary of the invention

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0024] The embodiment of the present application provides a concrete wall reinforcement positioning device, which can solve the problems of re-welding the reinforcement positioning template at the bottom of the wall column reinforcement in the related art, resulting in the deviation of the wall column reinforcement and the misalignment and overflow of the wall column concrete due to loose template joints and poor verticality.
[0025] See also Figures 1 to 3 As shown, the embodiment of the present application provides a concrete wall reinforcement positioning device, including a wall column positioning device 1, including a first support rod 10 and angle irons 11 connected to both ends of the first support rod 10, and the connection method between the angle iron 11 and the first support rod 10 includes but is not limited to welding connection;
[0026] The joint limiting device 2 comprises a second support rod 20 and hard plastic plates 21 connected to both ends of the second support rod 20. The hard plastic plates 21 are plastic products with high hardness and mechanical strength. The hard plastic plates 21 can be directly collected from waste materials at the construction site.
[0027] The connecting piece is used to connect the first support rod 10 and the second support rod 20, and the first support rod 10 and the second support rod 20 are arranged in parallel. At this time, the lengths of the first support rod 10 and the second support rod 20 are also the same.
[0028] In the present application, the wall column positioning device 1 and the joint limiting device 2 can be directly assembled at the construction site through the connecting piece, and the wall column positioning device 1 and the joint limiting device 2 are prefabricated in advance in batches in the project. When the connected wall column positioning device 1 and the joint limiting device 2 are used, the starting position of the wall column template is positioned and limited to the inner corner of the angle iron 11, and the angle iron 11 is fixed to the structural floor slab by iron nails. The length and width of the angle iron 11 are set to 100mm, and the first support rod 10 supports the angle iron 11 at both ends, which further fixes the template.
[0029] When the starting position of the template is positioned on the angle iron 11, the hard plastic plate 21 is in contact with the template. The length and width of the hard plastic plate 21 are set to 200 mm. The second support rod 20 supports the hard plastic plate 21 at both ends, thereby effectively controlling the verticality of the template joints, preventing leakage of mortar at the template joints, and improving the quality of concrete molding at the construction site.
[0030] Traditionally, tape is applied to the joints of the template or wooden strips are nailed to the joints of the template. The tape is mainly used to prevent leakage of the top plate, and the use position is limited. After the tape is applied to the template, it is easy to be damaged or not firmly attached before pouring concrete, which still causes leakage. Nailing wooden strips is mainly used to prevent leakage of the vertical template, and the use position is limited. The wooden strips are fixed on the outside of the template, which can only prevent the slurry from overflowing the outside of the template, but cannot prevent the overflow of the template joints. Therefore, the first support rod 10, angle iron 11, second support rod 20 and hard plastic board 21 used in this application are used to position and limit the position of the template. The structure is more stable than the traditional tape and wooden strip nailing, and the template support positioning and leakage prevention effect are better. It can be assembled on the construction site, which is conducive to improving construction efficiency.
[0031] In some alternative embodiments, see Figure 2 , a plurality of strip ribs 6 are distributed on the side of the hard plastic plate 21 away from the second support rod 20, and the strip ribs 6 are vertically arranged, and the interval between adjacent strip ribs 6 is between 8mm and 10mm, preferably 10mm. Under the action of the strip ribs 6, the overall strength of the hard plastic plate 21 is higher, and the close contact between the strip ribs 6 and the template can increase the stability of the overall structure, prevent displacement or deformation caused by external force or vibration, and when pouring concrete, the close fit between the strip ribs 6 and the template can effectively prevent the leakage of concrete or other materials, ensuring the quality and safety of construction.
[0032] In some embodiments, the thickness of the strip ribs 6, the hard plastic plate 21 and the angle iron 11 are all set between 3 mm and 5 mm, preferably 5 mm, for ease of factory processing.
[0033] In some alternative embodiments, see Figure 3 The connecting member includes a third support rod 3, which is vertically connected between the first support rod 10 and the second support rod 20, and the two ends of the third support rod 3 are respectively located in the middle of the first support rod 10 and the second support rod 20. Thus, the first support rod 10 and the second support rod 20 are connected, and the third support rod 3 is connected by welding, which is convenient for processing.
[0034] In the present application, the lengths of the first support rod 10, the second support rod 20 and the third support rod 3 are controlled by the dimensions of the wall columns at the construction site. Therefore, when processing the first support rod 10, the second support rod 20 and the third support rod 3, the distance between the wall columns needs to be measured in advance.
[0035] In some alternative embodiments, see Figure 3In order to improve the stability of the first support rod 10 and the second support rod 20, horizontal rods 4 are also arranged on both sides of the first support rod 10. The two horizontal rods 4 are coaxially located in the middle position of the first support rod 10, and the axes of the two horizontal rods 4 are coplanar and perpendicular to the axis of the first support rod 10, thereby forming a cross structure on the first support rod 10, which is more stable in use and reduces shaking.
[0036] In some alternative embodiments, see Figure 3 The first support rod 10, the second support rod 20, the third support rod 3 and the horizontal rod 4 are all made of steel bars. The diameter of the steel bars is set between 12 mm and 14 mm. There are a lot of steel bar waste at the construction site. The steel bar waste is collected and re-produced in batches in the factory into the first support rod 10, the second support rod 20, the third support rod 3 and the horizontal rod 4. The recycling of resources saves costs and is in line with the development of building energy conservation.
[0037] In some optional implementations, see Figure 2 and Figure 3 Since the hard plastic plate 21 is made of plastic, it is not convenient to directly weld the steel bar and the hard plastic plate 21. Therefore, a connecting sleeve 5 is provided on the side of the hard plastic plate 21. When the second support rod 20 is inserted into the connecting sleeve 5, the installation is convenient.
