Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a device for fixing positioning bars at the bottom of a wall and a construction method. Background Art

[0002] There are two ways to position the bottom reinforcement of traditional shear walls and column formwork: the first is to drill holes in the floor slab and insert reinforcement. The second is to weld short steel bars directly to the vertical main reinforcement of the shear wall and column. However, the first method will damage and block the electromechanical pipelines and expose the steel bars. The second method is to weld the positioning bars on the stress-bearing steel bars, which will seriously affect the stress-bearing steel bars and cause safety hazards to the engineering structure.

[0003] For example, a construction method for the positioning bars of a cast-in-place structure wall column formwork. The main technical principle of this patent is to adopt a construction method for the positioning bars of a cast-in-place structure wall column formwork. By pre-embedded auxiliary steel bars and the installation of positioning bars, the problem of welding on the main bars of the wall column is avoided, and the construction efficiency is improved. Specifically, first provide HRB400 steel bars and positioning bars of corresponding lengths, then pre-embed the auxiliary steel bars, and finally pre-embed the positioning bars in the concrete and weld them to the side of the auxiliary steel bars. This construction method can effectively avoid the problem of welding the main bars of the wall column and improve the stability and safety of the construction.

[0004] The positioning bars currently used are two additional bars embedded in advance before pouring the previous layer. The embedded length is 150mm, the leakage length is 250mm, the total length is 400mm, the diameter of the embedded steel bar is 10mm, and the number of wires tied to the main bar should be 3 or 4. A transverse positioning bar is welded before closing the mold. The two ends of the positioning bar should be cut flat and painted with anti-rust paint. The diameter of the steel bar is 10mm, and the length is the wall thickness-2mm. A positioning bar is set at an interval of 500mm. This construction method is material-consuming and time-consuming. Sometimes the positioning bar is directly welded to the main bar, affecting the overall structural performance. There are also cases where the positioning bar is directly buried by drilling holes without pre-embedding, causing damage to the pre-buried water and electricity pipes. Summary of the invention

[0005] In order to reduce the template positioning cost, the present application provides a wall bottom positioning rib fixing device and a construction method.

[0006] In the first aspect, the present application provides a wall bottom positioning rib fixing device that adopts the following technical solution: A device for fixing positioning bars at the bottom of a wall, comprising: A formwork body, wherein the formwork body is arranged vertically to the ground, and two parallel formwork bodies form a pouring cavity for pouring concrete; A fixing device fixes the two parallel template bodies, including positioning ribs and positioning plates arranged at both ends of the positioning ribs, the positioning ribs are customized according to the size of the on-site wall, the positioning plates are vertically fixed to the positioning ribs, the two positioning plates are respectively abutted against the opposite sides of the two template bodies, and are fixed to the template bodies by an air nail gun, and the bottom edge of the positioning plate is fixed on the ground.

[0007] By adopting the above technical scheme, the positioning reinforcement is customized according to the on-site wall size to ensure that it matches the size of the formwork body and the casting cavity, thereby providing stable support for the formwork body without damaging the main reinforcement. At the same time, the positioning plate is vertically fixed to the positioning reinforcement and fixed to the formwork body by an air nail gun to ensure accurate and firm positioning, thereby avoiding potential damage to the main reinforcement during construction. Due to the ingenious design of the positioning reinforcement and the positioning plate, no additional pre-embedded work is required during the installation of the formwork body, thereby avoiding interference with and damage to the pre-embedded water and electricity pipelines. Secondly, the positioning reinforcement and positioning plate used are simple and low-cost components, which are easy to purchase and process. The positioning reinforcement is customized according to the on-site size, which reduces waste and unnecessary adjustment time. The construction process is concise and clear, and workers can quickly master and efficiently complete the installation work, thereby reducing the overall cost and reducing the formwork positioning cost.

[0008] Preferably, the positioning plate is L-shaped, including an abutment plate abutting against the template body, and a fixing plate vertically arranged with the abutment plate and in contact with the ground; the fixing plate is located below the template body and extends in a direction away from the casting cavity and is fixed to the ground.

[0009] By adopting the above technical solution, the positioning plate is set to an L-shaped plate, and the abutment plate fits tightly against the formwork body to ensure that the formwork will not shift during the pouring process. The combination of the abutment plate and the fixed plate provides a solid support for the formwork body. The stable positioning plate design reduces the risk of movement or tilting of the formwork during concrete pouring, thereby improving construction safety. At the same time, the fixed plate fits against the ground and extends away from the pouring cavity, so that the positioning plate can be more easily fixed to the ground, increasing the stability of the entire pouring structure. Due to the stability of the positioning plate, the cast concrete structure has more precise dimensions and a smoother surface, thereby improving the overall construction quality. Furthermore, since rework and material waste caused by formwork movement or damage are reduced, it helps to save construction costs and further reduce formwork positioning costs.

[0010] Preferably, the height of the positioning rib is 0.6-0.7 times the height of the abutment plate.

[0011] By adopting the above technical solution, the height of the locating rib is set to 0.6-0.7 times the height of the abutment plate, which can more effectively fix the formwork body in the predetermined position and reduce the risk of displacement due to external force or vibration. The height setting of the locating rib helps to ensure that the locating rib can provide sufficient support while avoiding stability problems that may be caused by excessively high locating ribs. At the same time, the appropriate locating rib height helps to reduce material waste and unnecessary processing costs. By optimizing the structural design of the locating rib height, the manufacturing cost can be reduced, while reducing the additional costs incurred due to adjustments or repairs during construction.

[0012] Preferably, a positioning groove is provided on a side of the abutment plate away from the template body, and the positioning rib is placed in the positioning groove.

[0013] By adopting the above technical solution, a positioning groove is opened on the abutment plate. After the size of the positioning rib is determined, the positioning rib is installed in the positioning groove, which facilitates the placement of the positioning rib. When the positioning rib and the abutment plate are fixed, there is no need to measure the installation position of the positioning rib. The positioning rib and the positioning plate can be fixed directly, thereby further improving construction efficiency.

[0014] Preferably, the positioning groove is formed as a blind hole, and the depth of the positioning groove is 0.5-0.8 times the thickness of the abutment plate.

[0015] By adopting the above technical solution, the blind hole design forms a strong mechanical connection between the positioning groove and the abutment plate. Since the positioning groove does not completely penetrate the abutment plate, a portion of the thickness of the plate is retained, which helps to maintain the overall structural strength of the plate and prevent structural weakening caused by the opening of holes. The depth of the positioning groove is set to 0.5-0.8 times the thickness of the abutment plate. This ratio can ensure that the positioning rib can be firmly embedded therein to achieve precise positioning and fixation.

[0016] Preferably, the positioning rib and the positioning plate are tightly fixed by a pneumatic nail gun.

[0017] By adopting the above technical solution, the use of an air nail gun for fixing is simple and fast, which can greatly improve construction efficiency and shorten the project cycle. The cost of the air nail gun and its consumables is relatively low and maintenance is simple, which further reduces the cost of template positioning. At the same time, it avoids the impact of structural performance that may be caused by traditional welding methods, thereby improving construction efficiency and ensuring structural performance.

[0018] Preferably, the positioning plate is made of high-strength material.

[0019] By adopting the above technical solution, the positioning plate is made of high-strength material to ensure that it will not be deformed or damaged during use, thereby improving the stability and durability during use and improving the construction quality and safety.

[0020] In a second aspect, the present application provides a construction method for positioning reinforcement at the bottom of a wall, which adopts the following technical solution: A construction method for positioning reinforcement at the bottom of a wall, comprising the following steps: Customize positioning bars according to the on-site wall size; Insert the positioning rib into the installation groove of the positioning plate, and use an air nail gun to fix the positioning rib on the positioning plate; Fit the abutment plate of the positioning plate to the formwork body, and use an air nail gun to fix the abutment plate to the formwork body, and then fix the fixing plate to the ground with screws; After the formwork body is fixed, concrete is poured into the pouring cavity formed between two parallel formwork bodies.

[0021] By adopting the above technical solution, the construction method of the positioning ribs at the bottom of the wall includes the following steps: the first step is to customize the positioning ribs according to the size of the wall on site; the second step is to insert the positioning ribs into the installation grooves provided in the positioning plate, and use an air nail gun to fix the positioning ribs on the positioning plate; the third step is to fit the abutment plate of the positioning plate with the formwork body, and use an air nail gun to fix the abutment plate with the formwork body, and then fix the fixing plate to the ground with screws; the fourth step is to pour concrete in the casting cavity formed between the two parallel formwork bodies after the formwork body is fixed. In this way, the positioning ribs can be pre-made according to the specific size of the wall on site, ensuring the matching degree between the positioning ribs and the wall, improving the construction accuracy, and using an air nail gun to fix the positioning ribs is not only simple and quick to operate, but also avoids the structural performance impact that may be caused by the traditional welding method, thereby improving the construction efficiency and ensuring the structural performance. Workers can quickly master and efficiently complete the installation work, thereby reducing the overall cost and the formwork positioning cost.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The positioning ribs are customized according to the size of the on-site wall to ensure that they match the size of the formwork body and the casting cavity, thereby providing stable support for the formwork body without damaging the main reinforcement. At the same time, the positioning plate is fixed vertically to the positioning ribs and fixed to the formwork body by an air nail gun to ensure accurate and firm positioning, avoiding potential damage to the main reinforcement during construction. Due to the ingenious design of the positioning ribs and positioning plates, no additional pre-embedded work is required during the installation of the formwork body, avoiding interference and damage to the pre-embedded water and electricity pipelines. Secondly, the positioning ribs and positioning plates used are simple and low-cost components, easy to purchase and process. The positioning ribs are customized according to the on-site size, reducing waste and unnecessary adjustment time. The construction process is concise and clear, and workers can quickly master and efficiently complete the installation work, thereby reducing the overall cost and the formwork positioning cost; 2. The positioning plate is set to an L-shaped plate, and the abutment plate fits tightly against the formwork body to ensure that the formwork will not shift during the pouring process. The combination of the abutment plate and the fixed plate provides a solid support for the formwork body. The solid positioning plate design reduces the risk of movement or tilting of the formwork during concrete pouring, thereby improving construction safety. At the same time, the fixed plate fits against the ground and extends away from the pouring cavity, so that the positioning plate can be more easily fixed to the ground, increasing the stability of the entire pouring structure. Due to the stability of the positioning plate, the cast concrete structure has more precise dimensions and a smoother surface, thereby improving the overall construction quality. Furthermore, since rework and material waste caused by formwork movement or damage are reduced, it helps to save construction costs and further reduce formwork positioning costs.

[0026] The present application embodiment discloses a device for fixing the positioning ribs at the bottom of a wall. Figure 1 The wall bottom positioning rib fixing device includes a template body 1 and a fixing device 2.

[0027] The formwork body 1 is arranged vertically to the ground, and a casting cavity is formed between two parallel formwork bodies 1 for concrete casting. In one embodiment, the formwork body 1 is a wooden formwork.

[0029] Specifically, the positioning ribs 21 are customized according to the dimensions of the on-site wall to ensure that they fully match the dimensions of the formwork body 1 and the casting cavity. This customized design enables the positioning ribs 21 to provide stable support for the formwork body 1 without damaging the main ribs.

[0030] The positioning plate 22 is vertically fixed to the positioning rib 21. The two positioning plates 22 are respectively tightly fitted on the opposite sides of the two template bodies 1 and are firmly fixed to the template bodies 1 by a pneumatic nail gun. Specifically, the positioning plate 22 is designed to be L-shaped, and the positioning plate 22 of this shape includes an abutment plate 221 that is tightly fitted to the template body 1, and a fixing plate 222 that is vertically arranged with the abutment plate 221 and fits the ground.

The design of the L-shaped positioning plate 22 not only provides a stable support for the formwork body 1, but also effectively reduces the risk of movement or tilting of the formwork during concrete pouring, thereby improving construction safety.

[0032] A positioning groove 2211 is provided on the abutment plate 221. The positioning groove 2211 is a blind hole groove, and the depth is set to 0.5-0.8 times the thickness of the abutment plate 221.

At the same time, the positioning plate 22 is vertically fixed to the positioning rib 21 and fixed to the formwork body 1 by an air nail gun to ensure accurate and firm positioning, thereby avoiding potential damage to the main reinforcement during construction. Due to the ingenious design of the positioning rib 21 and the positioning plate 22, no additional pre-embedded work is required during the installation of the formwork body 1, thereby avoiding interference with and damage to the pre-embedded water and electricity pipelines. Secondly, the positioning rib 21 and positioning plate 22 used are simple and low-cost components, which are easy to purchase and process.

By accurately measuring the size of the on-site wall and combining it with the construction requirements, the positioning ribs 21 of appropriate length and diameter are customized.

[0035] S2, insert the positioning rib 21 into the installation groove provided in the positioning plate 22, and use an air nail gun to fix the positioning rib 21 on the positioning plate 22; By pre-forming a mounting groove on the positioning plate 22, the positioning rib 21 can be conveniently placed at a predetermined position and quickly fixed using a pneumatic nail gun. This fixing method is not only easy to operate, but also can ensure a tight connection between the positioning rib 21 and the positioning plate 22.

[0036] S3, fit the abutment plate 221 of the positioning plate 22 to the template body 1, and use an air nail gun to fix the abutment plate 221 to the template body 1, and then fix the fixing plate 222 to the ground with screws; By closely fitting the abutment plate 221 to the template body 1 and fixing it with a pneumatic nail gun, the template body 1 can be prevented from moving or tilting during the construction process. At the same time, the fixing plate 222 is fixed to the ground by screws, which further enhances the stability of the entire device.

[0037] S4. After the formwork body 1 is fixed, concrete is poured into the pouring cavity formed between two parallel formwork bodies 1.

[0038] When the wall casting construction is completed, since the stability and positioning accuracy of the fixing device 2 in the previous steps are guaranteed, it can be ensured that the cast concrete structure has accurate dimensions and a smooth surface.

[0039] The implementation principle of the construction method of the bottom positioning rib of the wall in the embodiment of the present application is as follows: the construction method of the bottom positioning rib 21 of the wall includes the following steps: the first step is to customize the positioning rib 21 according to the size of the wall on site; the second step is to insert the positioning rib 21 into the installation groove provided by the positioning plate 22, and use the air nail gun to fix the positioning rib 21 on the positioning plate 22; the third step is to fit the abutment plate 221 of the positioning plate 22 with the template body 1, and use the air nail gun to fix the abutment plate 221 with the template body 1, and then fix the fixing plate 222 with the ground by screws; the fourth step is to pour concrete in the pouring cavity formed between the two parallel template bodies 1 after the template body 1 is fixed.
