Description

Technical Field

[0001] This invention belongs to the field of civil engineering construction technology, specifically relating to a basement shear wall formwork reinforcement device and process. Background Technology

[0002] Currently, inspections of concrete forming quality after demolding (wooden formwork) of shear wall concrete pouring have revealed that formwork bursts and misalignments are particularly prominent at the formwork joints. Observations show that the removed formwork is riddled with bolt holes, requiring multiple reuses. This easily leads to grout leakage, honeycombing, and surface defects during concrete pouring. Although the bolt holes are sealed during concrete pouring, omissions are still evident. Therefore, this solution was developed. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a basement shear wall formwork reinforcement device and process, which achieves formwork installation and fixation without drilling while ensuring the formwork is fixed and stable by setting reinforcement plates.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a basement shear wall formwork reinforcement device, comprising multiple fixed panels arranged around the perimeter of the pouring area, each fixed panel including multiple strip connecting plates, multiple reinforcing plates, and a template, wherein the strip connecting plates are located between two templates, and the strip connecting plates are provided with multiple screw holes, the reinforcing plates are slidably connected to the outward side of the strip connecting plates, the reinforcing plates are provided with connecting holes adapted to the screw holes, the upper and lower ends of the inward side of the reinforcing plates are respectively attached to the surfaces of two templates, and multiple reinforcing plates are provided on a single strip connecting plate; tie rods are provided between the mutually facing strip connecting plates, the tie rods passing through the screw holes of two strip connecting plates and the connecting holes of two reinforcing plates.

[0005] Furthermore, the outer side of the strip connecting plate is provided with a sliding groove, and the reinforcing plate has a slider, which is engaged in the sliding groove for sliding connection.

[0006] Furthermore, the reinforcement device also includes a first fixing plate and a second fixing plate. The first fixing plate is a straight plate, and its two ends are respectively connected to two strip connecting plates or to two reinforcing pieces. The second fixing plate includes a short section, a connecting section, and a long section. The short section and the long section are connected by the connecting section. The connecting section is vertically arranged. The short section is used to connect to the reinforcing pieces, and the long section is used to connect to the strip connecting plates.

[0007] Furthermore, the reinforcing plates on adjacent strip connecting plates are staggered, and the reinforcing plates on two strip connecting plates separated by one strip connecting plate are vertically aligned. The long section of the adjacent upper second fixing plate is in contact with the vertical section of the lower second fixing plate.

[0008] Furthermore, the reinforcement device also includes a template deformation detection component, which includes a self-retracting wire feeding wheel and a sensing component. The traction wire in the self-retracting wire feeding wheel is fixed after winding around the outer periphery of all templates on the same horizontal layer, and the sensing component is used to sense the movement and changes of the traction wire.

[0009] Furthermore, the self-retracting reel is fixedly mounted on the mounting base. The self-retracting reel includes a rotating shaft and a traction line. The rotating shaft is rotatably connected to the mounting base. A take-up reel is fixedly mounted on the circumference of the rotating shaft. A take-up groove is provided on the circumference of the take-up reel, and the traction line is wound in the take-up groove.

[0010] Furthermore, one end of the rotating shaft passes through the end face of the mounting base and is provided with a fan-shaped plate. The fan-shaped plate is provided with a plurality of fan-shaped holes arranged in a ring at intervals along the center of the fan-shaped plate. The sensing component includes an infrared emitter and an infrared receiver, which are located above and below the fan-shaped plate, respectively.

[0011] Furthermore, the included angle between the two sides of the fan-shaped hole is 5-8 degrees, and the included angle between the adjacent edges of two adjacent fan-shaped holes is 2-5 degrees.

[0012] A basement shear wall formwork reinforcement process, which employs a basement shear wall formwork reinforcement device for installation, includes the following steps:

[0013] S1. First, install the template around the pouring area, then install the strip connecting plate on the template. The height between two perpendicular templates is different. Adjust the position of the reinforcing plate. Multiple tie rods pass through the screw holes of the two strip connecting plates facing each other and the connecting holes on the reinforcing plate. Then install the next template on the strip connecting plate and tighten the pre-tightening part of the reinforcing plate to make it fit the surface of the two templates.

[0014] S2. Repeat step S1 until the template is installed. Then install the first fixing plate and the second fixing plate between adjacent strip connecting plates. The total number of the first fixing plate and the second fixing plate between adjacent strip connecting plates should be at least two.

[0016] S1. First, install the template around the pouring area, then install the strip connecting plate on the template. The height between two perpendicular templates is different.

[0019] S4. Segmented pouring is carried out. During the pouring process, the template at the same horizontal height expands, causing the template to bulge outward. The traction line is pulled, and the sensing component detects the change in the angle of the shaft on the self-retracting wire reel. If the angle change exceeds 5-10°, a warning is issued, the pouring is stopped, and inspection and maintenance are carried out. After inspection and maintenance, the pouring continues until the pouring is completed.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] This invention achieves drill-free installation of the templates by using strip connecting plates and reinforcing plates set between two templates. The upper and lower ends of the reinforcing plates are attached to the outer wall of the templates, and the matrix arrangement of multiple reinforcing plates enables multi-point positioning, ensuring the reliability of template installation. It solves the problem of template bursting and misalignment during concrete pouring caused by loose joints in existing template splicing. Furthermore, the reinforcement construction largely avoids drilling holes in the templates, increasing the number of template reuses and the quality of concrete forming, while saving construction costs.

[0033] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0034] Example 1

[0035] like Figures 1-7 As shown in the figure, this embodiment provides a basement shear wall formwork reinforcement device, which includes multiple fixing panels, a first fixing plate 4 and a second fixing plate 5. The multiple fixing panels are arranged around the perimeter of the pouring area, as shown in the figure.

[0036] The fixed panel includes multiple strip connecting plates 1, multiple reinforcing plates 2, and templates 3, with templates 3 made of wood. The thickness of the strip connecting plates can be set to 15mm, 14mm, 12mm, or 10mm, and its processing thickness is mainly adjusted according to the thickness of the templates on site. The strip connecting plates 1 are located between two templates 3. Multiple screw holes 12 are provided on the strip connecting plates 1. In this embodiment, there are 9 screw holes 12, with a diameter of 11mm. The distance between each screw hole is no more than 200mm. A sliding groove 11 is also provided on the outward-facing side of the strip connecting plates 1. The outward-facing sliding groove 11 can prevent soil debris from falling into the sliding groove 11 during assembly and disassembly, thus affecting the movement of the reinforcing plates 2. The sliding groove 11 is a T-shaped groove, and the screw holes 12 directly penetrate the entire T-shaped groove. Each connecting rod is equipped with at least two reinforcing plates 2. In this scheme, each strip connecting plate 1 has two or three reinforcing plates 2. Specifically, adjacent strip connecting plates 1 have two reinforcing plates 2 on one surface and three reinforcing plates 2 on the other surface. The back of the reinforcing plate 2 is provided with a slider 21 that matches the sliding groove 11. The surface of the reinforcing plate 2 is provided with a connecting hole 22 that corresponds to the screw hole 12. The upper and lower ends of the inner side of the reinforcing plate 2 are respectively attached to the surfaces of the two templates 3.

[0037] In this scheme, most of the existing shear walls are rectangular. The rectangular casting area has four sides. The templates 3 installed on each pair of corresponding side walls are at the same height. The heights of two perpendicular templates 3 are inconsistent because during the process of threading the tie rods 8, the two strip connecting plates 1 in the front-to-back direction and the two strip connecting plates 1 in the left-to-right direction cannot be at the same height. Otherwise, there will be interference when the tie rods 8 pass through.

[0038] In this scheme, four templates 3 are installed sequentially, and then strip connecting plates 1 are installed on top of the templates 3. Screws are threaded through each pair of corresponding strip connecting plates 1. Some screws pass through the connecting holes 22 of one reinforcing plate 2, the screw holes 12 of one strip connecting plate 1, the screw holes 12 of another strip plate, and the connecting rod of another reinforcing plate 2. Pull nuts are installed on the outside of the two connecting holes 22. Other screws pass through the screw holes 12 of one strip connecting plate 1 and the screw holes 12 of another strip plate. Pull nuts are installed on the outside, and multiple pull rods 8 are tightened through each other to achieve fixation. In addition, due to the installation of reinforcing plates 2, the upper and lower ends of the reinforcing plates 2 will abut against the surfaces of the upper and lower templates 3. Through the matrix-like limiting of multiple reinforcing plates 2, the template 3 is fixed, realizing the template 3 installation and fixation without drilling. Compared with the existing template 3 drilling fixation method, the reinforcement device in this solution largely avoids drilling holes in the template 3 during reinforcement construction, increases the turnover rate of template 3 and the quality of concrete molding, and saves construction costs.

[0039] The first fixing plate 4 is a straight plate, and its two ends are connected to two strip connecting plates 1 or two reinforcing pieces 2 respectively; the second fixing plate 5 includes a short section 51, a connecting section 52 and a long section 53. The short section and the long section 53 are connected by the connecting section 52. The connecting section 52 is set vertically. The short section 51 is used to connect with the reinforcing piece 2, and the long section 53 is used to connect with the strip connecting plate 1.

[0040] like Figure 2 As shown, preferably, the reinforcing pieces 2 on adjacent strip connecting plates 1 are staggered, and the reinforcing pieces 2 on two adjacent strip connecting plates 1 that are separated by one strip connecting plate 1 correspond to each other vertically. The long section 53 of the adjacent upper second fixing plate 5 is in contact with the vertical section of the lower second fixing plate 5.

[0041] By setting a first fixing plate 4 and a second fixing plate 5 to connect two adjacent strip connecting plates 1, when the template 3 on one of the strip connecting plates 1 shifts vertically or collapses during installation or pouring, the first fixing plate 4 and the second fixing plate 5 will evenly transfer the force on the strip connecting plate 1 downwards until it is transmitted to the ground for support. This results in good force dissipation and a more stable connection. Moreover, the sum of the number of the first fixing plate 4 and the second fixing plate 5 between two adjacent strip connecting plates 1 is at least two, and the two-point fixation improves the stability of the entire reinforcement device.

[0042] This embodiment also provides a reinforcement device for basement shear wall formwork reinforcement process, which is installed using a basement shear wall formwork reinforcement device, including the following steps:

[0043] S1. First, install template 3 around the perimeter of the pouring area. Then, install strip connecting plates 1 on template 3. The heights of two perpendicular templates 3 are different. Adjust the position of reinforcing plate 2. Multiple tie rods 8 pass through the two screw holes 12 facing the two strip connecting plates 1 and the connecting holes 22 on the reinforcing plate 2. Then, install the next template 3 on the strip connecting plate 1 and tighten the pre-tightening parts of the reinforcing plate 2 to make it fit the surfaces of the two templates 3.

[0044] S2. Repeat step S1 until template 3 is installed. Then install the first fixing plate 4 and the second fixing plate 5 between adjacent strip connecting plates 1. The total number of the first fixing plate 4 and the second fixing plate 5 between adjacent strip connecting plates 1 should be at least two.

[0045] Preferably, the installation of the first fixing plate 4 and the second fixing plate 5 in step S2 can also be carried out directly after the two strip connecting plates 1 are installed.

[0046] Example 2

[0047] like Figures 1-10As shown, the difference between this embodiment and embodiment 1 is that the reinforcement device also includes a template deformation detection component 6, which is used to detect the change in the outer perimeter length of the template 3 at the same height.

[0048] The template deformation detection component 6 includes a self-retracting wire feeding reel 61 and a sensing component. The traction wire 67 inside the self-retracting wire feeding reel 61 is fixed after winding around the outer periphery of all templates 3 on the same horizontal layer. The sensing component is used to sense the movement and changes of the traction wire 67. The self-retracting wire feeding reel 61 is fixedly mounted on the mounting base 63. The self-retracting wire feeding reel 61 includes a rotating shaft 62 and a traction wire 67. The rotating shaft 62 is rotatably connected to the mounting base 63. A reset torsion spring is also provided at the connection between the rotating shaft 62 and the mounting base 63. A take-up reel is fixedly mounted on the circumference of the rotating shaft 62. A take-up ring groove is provided on the circumference of the take-up reel. The traction wire 67 is wound in the take-up ring groove and one end is fixed to the take-up groove. On the upper part, one end of the rotating shaft 62 passes through the end face of the mounting base 63 and is provided with a fan-shaped plate 64. The fan-shaped plate 64 is provided with a plurality of fan-shaped holes 641 arranged in a ring along the center of the fan-shaped plate 64. The included angle between the two sides of the fan-shaped hole 641 is 5-8 degrees. Preferably, the included angle between the two sides of the fan-shaped hole 641 is 5 degrees. In this embodiment, the included angle between the adjacent edges of two adjacent fan-shaped holes 641 is 2-5 degrees. Preferably, the included angle between the adjacent edges of two adjacent fan-shaped holes 641 is 2 degrees. The sensing component includes an infrared emitter 65 and an infrared receiver 66. The infrared emitter 65 and the infrared receiver 66 are located above and below the fan-shaped plate 64, respectively.

[0049] Preferably, multiple template deformation detection components 6 are connected to the column 7, the column 7 is fixedly set on one side of the pouring area, and multiple mounting bases 63 are connected to the column 7 through connecting plates, with two connecting plates respectively set above and below the mounting base 63.

[0050] This embodiment also provides a basement shear wall formwork reinforcement process, which uses the above-mentioned device and includes the following steps:

[0051] S1. First, install template 3 around the perimeter of the pouring area. Then, install strip connecting plates 1 on template 3. The heights of two perpendicular templates 3 are different. Adjust the position of reinforcing plate 2. Multiple tie rods 8 pass through the two screw holes 12 facing the two strip connecting plates 1 and the connecting holes 22 on the reinforcing plate 2. Then, install the next template 3 on the strip connecting plate 1 and tighten the pre-tightening parts of the reinforcing plate 2 to make it fit the surfaces of the two templates 3.

[0052] S2. Repeat step S1 until template 3 is installed. Then install the first fixing plate 4 and the second fixing plate 5 between adjacent strip connecting plates 1. The total number of first fixing plates 4 and second fixing plates 5 between adjacent strip connecting plates 1 should be at least two. Preferably, the installation of the first fixing plate 4 and the second fixing plate 5 in step S2 can also be carried out directly after the two strip connecting plates 1 are installed.

[0053] S3. Install self-retracting wire-laying wheels 61 on the horizontal surface corresponding to each template 3. The self-retracting wire-laying wheels 61 are fixed to the wall after passing around the four templates 3.

[0054] S4. Segmented pouring is performed. During the pouring process, the template 3 at the same horizontal height expands, causing the template 3 to bulge outward. The traction line 67 is pulled, and the sensing component detects the angle change of the shaft 62 on the self-retracting reel 61. If the angle change exceeds 5-10°, a warning is issued, pouring is stopped, and maintenance is performed. After maintenance, pouring continues until the pouring is completed. In this embodiment, a warning is issued when the angle change exceeds 7 degrees. That is, the warning is issued when the infrared transmitter 65 and the infrared receiver 66 go from a mutual sensing state to a loss of sensing state and then back to a mutual sensing state.

[0055] It is worth noting that the template deformation detection component 6 in this solution can only be implemented after being reinforced by the reinforcement device mentioned in this solution. This is because the reinforcement device in this solution fixes the template 3 at multiple points and reinforces adjacent templates through the first fixing plate 4 and the second fixing plate 5. During the expansion of the template, the template will not burst open directly due to the cooperation and stress transmission between the first fixing plate 4, the second fixing plate 5, the strip connecting plate 1 and the reinforcement plate 2. Only then can the template deformation detection component 6 of this solution be applied. If the template deformation detection component 6 is used directly in the existing installation method, the template may burst open directly without the template deformation detection component 6 being able to issue a warning in time.

[0056] In Example 2, by setting up the template deformation detection component 6, the bulging condition of the template 3 can be detected even when it is not easily observed by the human eye in the early stage of bulging, and maintenance can be carried out, which greatly improves the pouring efficiency and concrete forming quality.

[0057] Preferably, after the reinforcement device is installed, back ribs need to be set on the outer periphery of the template 3 and the strip connecting plate 1 in both embodiments. The back ribs include horizontal steel pipes and vertical steel pipes. The back ribs are existing structures and will not be described in detail here. The horizontal steel pipes and vertical steel pipes surround the outside of the template 3, and the water-stop screws pass through the horizontal steel pipes or vertical steel pipes and are tightened by nuts.

[0058] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
