[0033] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0034] Example 1

[0035] like Figure 1-Figure 7 As shown, this embodiment provides a basement shear wall formwork 3 reinforcement device, multiple fixed panels, a first fixed plate 4 and a second fixed plate 5, and the multiple fixed panels are arranged around the periphery of the casting area, as shown in the figure.

[0036] The fixed panel includes a plurality of strip connecting plates 1, a plurality of reinforcing plates 2 and a template 3, and the template 3 is made of a wooden board. The thickness of the strip connecting plate can be set to 15mm, 14mm, 12mm, and 10mm, and its processing thickness is mainly adjusted according to the thickness of the template on site. The strip connecting plate 1 is located between two templates 3, and a plurality of screw holes 12 are arranged on the strip connecting plate 1. In this embodiment, the number of screw holes 12 is 9, the diameter of the screw hole is 11mm, and the distance between each screw hole is not more than 200mm. The strip connecting plate 1 is also provided with a sliding groove 11 on the outward side. The outward sliding groove 11 can prevent soil debris from falling into the sliding groove 11 during disassembly and assembly, thereby affecting the movement of the reinforcing plate 2. The sliding groove 11 is a T-shaped groove, and the screw hole 12 directly passes through the entire T-shaped groove. At least two reinforcing sheets 2 are arranged on each connecting rod. In this solution, the number of reinforcing sheets 2 on each strip connecting plate 1 is 2 or 3. Specifically, the number of reinforcing sheets 2 on one surface of adjacent strip connecting plates 1 is 2, and the number of reinforcing sheets 2 on the other surface is 3. A slider 21 matching the sliding groove 11 is arranged on the back of the reinforcing sheet 2, and a connecting hole 22 corresponding to the screw hole 12 is arranged on the surface of the reinforcing sheet 2. The upper and lower ends of the inner side of the reinforcing sheet 2 are respectively in contact with the surfaces of the two templates 3.

[0037] The existing shear walls in this scheme are mostly rectangular, and the rectangular casting area has four sides. The height of the templates 3 installed on every two corresponding side walls is uniform, and the height of the two vertical templates 3 is inconsistent. This is because in the process of passing the tension screw 8, the two strip connecting plates 1 in the front and rear directions and the two strip connecting plates 1 in the left and right directions cannot be at the same height, otherwise there will be interference problems when the tension screw 8 passes through.

[0038] In this scheme, four-sided templates 3 are installed in sequence, and then strip connecting plates 1 are installed above the templates 3. Screws are passed through each pair of corresponding strip connecting plates 1. Some of the screws pass through the connection holes 22 of one reinforcement sheet 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 reinforcement sheet 2 in sequence. Pull nuts are set on the outsides of the two connection holes 22, and other screws pass through the screw holes 12 of one strip connecting plate 1 and the screw holes 12 of another strip plate in sequence. A tension nut is arranged on the outside, and fixation is achieved by tightening a plurality of tension screws 8 through them. In addition, since a reinforcement plate 2 is arranged, the upper and lower ends of the reinforcement plate 2 will press against the surfaces of the upper and lower templates 3. The template 3 is fixed by the matrix-type limiting of a plurality of reinforcement plates 2, and the template 3 is installed and fixed without punching holes. Compared with the existing method of fixing the template 3 by punching holes, the reinforcement device in this scheme avoids drilling holes in the template 3 to a large extent during the reinforcement construction, thereby improving the turnover times of the template 3 and the concrete molding quality, and saving construction costs.

[0039] The first fixing plate 4 is a straight plate, and the two ends of the first fixing plate 4 are respectively connected to two strip connecting plates 1 or to two reinforcing plates 2; the second fixing plate 5 includes a short-circuit section 51, a connecting section 52 and a long-circuit section 63, and the short-circuit end and the long-circuit section 63 are connected by the connecting section 52. The connecting section 52 is vertically arranged, the short-circuit section 51 is used to connect to the reinforcing plate 2, and the long-circuit section 63 is used to connect to the strip connecting plate 1.

[0040] like Figure 2 As shown, preferably, the reinforcing plates 2 on adjacent strip connecting plates 1 are arranged alternately, the reinforcing plates 2 on two separated strip connecting plates 1 separated by one strip connecting plate 1 correspond to each other up and down, and the long connecting section 63 of the adjacent and upper second fixed plate 5 is in contact with the vertical section of the lower second fixed plate 5.

[0041] By arranging the first fixing plate 4 and the second fixing plate 5 to connect the two adjacent strip connecting plates 1, when the formwork 3 on one of the strip connecting plates 1 deviates up and down or collapses during the installation process or the pouring process, the first fixing plate 4 and the second fixing plate 5 will evenly transfer the force on the strip connecting plate 1 downward until it is transmitted to the ground and supported by the ground, which has a good force release effect and a more stable connection. In addition, the sum of the first fixing plates 4 and the second fixing plates 5 between two adjacent strip connecting plates 1 is at least 2, and the two-point fixation improves the stability of the entire reinforcement device.

[0042] This embodiment also provides a basement shear wall formwork 3 reinforcement process, which uses a basement shear wall formwork 3 for installation, including the following steps:

[0043] S1. First install the formwork 3 around the pouring area, and then install the strip connecting plate 1 on the formwork 3. The heights of the two perpendicular formworks 3 are different. Adjust the position of the reinforcement sheet 2. Pass multiple tension screws 8 through the screw holes 12 facing the two strip connecting plates 1 and the connecting holes 22 on the reinforcement sheet 2. Then install the next formwork 3 on the strip connecting plate 1, and tighten the preload of the reinforcement sheet 2 to make it fit the surfaces of the two formworks 3.

[0044] S2. Repeat step S1 until the template 3 is installed, and 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 plates 4 and the second fixing plates 5 between adjacent strip connecting plates 1 is 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 directly performed after the two strip-shaped connecting plates 1 are installed.

[0046] Example 2

[0047] like Figure 1-Figure 10As shown, the difference between this embodiment and embodiment 1 is that the reinforcement device further includes a template deformation detection component 6, and the template deformation detection component 6 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 pay-off wheel 61 and a sensing component. The traction line 67 in the self-retracting pay-off wheel 61 is fixed after being wound around the outer periphery of all templates 3 on the same horizontal layer. The sensing component is used to sense the movement and change of the traction line 67. The self-retracting pay-off wheel 61 is fixedly arranged on the mounting seat 63. The self-retracting pay-off wheel 61 includes a rotating shaft 62 and a traction line 67. The rotating shaft 62 is rotatably connected in the mounting seat 63. A reset torsion spring is also arranged at the connection between the rotating shaft 62 and the mounting seat 63. A take-up drum is fixedly arranged on the circumference of the rotating shaft 62. A take-up ring groove is arranged on the circumference of the take-up drum. The traction line 67 is wound in the take-up ring groove and one end is fixed in the take-up change groove. On the upper part, one end of the rotating shaft 62 passes through the end face of the mounting seat 63 and is provided with a fan-shaped plate 64, and the fan-shaped plate 64 is provided with a plurality of fan-shaped holes 641 arranged at annular intervals along the center of the fan-shaped plate 64, and the angle between the two sides of the fan-shaped hole 641 is 5-8 degrees, preferably, the angle between the two sides of the fan-shaped hole 641 is 5 degrees, and the angle between the adjacent side lines of two adjacent fan-shaped holes 641 in this embodiment is 2-5 degrees, preferably, the angle between the adjacent side lines of two adjacent fan-shaped holes 641 is 2 degrees, and the sensing component includes an infrared transmitter 65 and an infrared receiver 66, and the infrared transmitter 65 and the infrared receiver 66 are respectively located above and below the fan-shaped plate 64.

[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 casting area, and multiple mounting seats 63 are connected to the column 7 through connecting plates. There are two connecting plates respectively set above and below the mounting seats 63.

[0050] This embodiment also provides a basement shear wall formwork 3 reinforcement process, which is operated using the above device and includes the following steps:

[0051] S1. First install the formwork 3 around the pouring area, and then install the strip connecting plate 1 on the formwork 3. The heights of the two perpendicular formworks 3 are different. Adjust the position of the reinforcement sheet 2. Pass multiple tension screws 8 through the screw holes 12 facing the two strip connecting plates 1 and the connecting holes 22 on the reinforcement sheet 2. Then install the next formwork 3 on the strip connecting plate 1, and tighten the preload of the reinforcement sheet 2 to make it fit the surfaces of the two formworks 3.

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

[0053] S3. Install a self-retracting pay-off wheel 61 on the horizontal plane corresponding to each template 3. The self-retracting pay-off wheel 61 is pulled around the four templates 3 and then fixed to the wall.

[0054] S4, perform segmented pouring. During the pouring process, the template 3 at the same level as the template 3 expands, causing the template 3 to bulge outward, and the traction line 67 is pulled. The sensing component senses the angle change of the rotating shaft 62 on the self-retracting pay-off wheel 61, and the angle change exceeds 5-10°, and a warning is issued, and the pouring is stopped and repair and maintenance are carried out. After the repair and maintenance, the pouring is continued until the pouring is completed. In this embodiment, a warning is issued when the angle changes by more than 7 degrees, that is, the infrared transmitter 65 and the infrared receiver 66 change from the mutual induction state to the loss of induction state and then to the mutual induction state, and a warning is issued.

[0055] It is worth noting that the template deformation detection component 6 in the present scheme must be reinforced with the reinforcement device mentioned in the present scheme before it can be implemented. Because the reinforcement device in the present scheme fixes the template 3 at multiple points, and the adjacent templates are reinforced by the first fixed plate 4 and the second fixed plate 5. When the mold is expanded, the template will not explode directly due to the cooperation and stress conduction between the first fixed plate 4, the second fixed plate 5, the strip connecting plate 1 and the processing sheet 2. Only then can the template deformation detection component 6 of the present scheme be applied. If the existing installation method directly adopts the template deformation detection component 6, the template may explode directly and the template deformation detection component 6 will not have time to warn.

[0056] In Example 2, by setting up the template deformation detection component 6, the expansion of the template 3 can be detected in the early stage of the expansion when it is difficult for human eyes to observe, and maintenance can be carried out, which greatly improves the pouring efficiency and concrete molding quality.

[0057] Preferably, after the reinforcement device is installed in the two embodiments, it is necessary to set a back rib on the outer periphery of the template 3 and the strip connecting plate 1. The back rib includes a transverse steel pipe and a vertical steel pipe. The back rib belongs to the existing structure and will not be repeated here. The transverse steel pipe and the vertical steel pipe surround the outer side of the template 3, and the water stop screw passes through the transverse steel pipe or the vertical steel pipe and is tightened by a nut.

[0058] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which shall fall within the scope of the present invention to be protected.
