[0027] Example

[0028] See also Figure 1-4 As shown, the technical solution provided by the utility model is as follows: an assembled prefabricated external shear wall comprises a shear wall body 1, the outer surface of the shear wall body 1 is sleeved with a first reinforcement seat 2 and a second reinforcement seat 3, both ends of the first reinforcement seat 2 close to the second reinforcement seat 3 are fixedly installed with plug blocks 4, both sides of the second reinforcement seat 3 close to the first reinforcement seat 2 are provided with slots 5, the top and bottom of the slots 5 are provided with limit slots 6, the inner end of the plug block 4 is provided with a limit mechanism 7, the outer end of the limit mechanism 7 is plugged into the inner side of the limit slot 6, the top of the first reinforcement seat 2 and the second reinforcement seat 3 are fixedly installed with plug blocks 4 ... The adjustable support members 8 are all fixedly installed; the limiting mechanism 7 includes a square groove 71, the square groove 71 is opened at the top and bottom of the insert block 4, the inner side of the square groove 71 is fixedly installed with a limiting spring 72, the outer side of the limiting spring 72 is fixedly installed with a limiting block 73, the outer end of the limiting block 73 is inserted into the interior of the limiting groove 6, and the limiting mechanism 7 is set. During use, the limiting spring 72 can resist the limiting block 73 and be inserted into the interior of the limiting groove 6, which can assist in supporting the combined installation of the first reinforcement seat 2 and the second reinforcement seat 3, and can improve the overall stability of the device.

[0029] Furthermore, the adjustable support member 8 includes a sleeve frame 81, which is fixedly installed on the top of the first reinforcement seat 2 and the second reinforcement seat 3. The inner side of the sleeve frame 81 is slidably connected with a supporting slide plate 82. The inner side of the supporting slide plate 82 is fit-connected with the outer side of the shear wall 1. A support rod 83 is fixedly installed on the outer side of the supporting slide plate 82. A fixing screw 84 is fixedly installed at the lower end of the support rod 83. The inner end of the fixing screw 84 passes through the support plate.

[0030] The locking cam 73 is in the locked state when the locking cam 73 is in the locked state, and the locking cam 73 is in the locked state when the locking cam 73 is in the locked state. 4 and the slot 5 lose their limit, and then the first reinforcement seat 2 and the second reinforcement seat 3 can be quickly disassembled and separated, which can improve the overall stability of the device. A pressing plate 77 is fixedly installed on the outer side of the slider 75. The cross-sectional shape of the slider 75 and the slide groove 74 is set to a convex shape. The device adopts a pressing plate 77, and the limiting block 73 can be driven inward by adjusting the slider 75 to pull the connecting shaft, so as to prompt the limiting block 73 to leave the limiting slot 6, which is convenient for quick disassembly and assembly of the device.

[0031] Furthermore, the side shape of the limit block 73 is set to a right-angled trapezoid, and the inclined surface of the limit block 73 is set on the side close to the second reinforcement seat 3. During the use of the device, by setting the limit block 73 in the shape of a right-angled trapezoid, the inclined surface of the limit block 73 can be used to assist in guiding the force, so that during installation, the limit block 73 can be guided to drive the limit spring 72 to contract. At this time, the limit spring 72 contracts into the square groove 71, so that the device can be quickly disassembled and maintained.

[0032] Furthermore, fixing plates 9 are fixedly installed at both the front and rear ends of the first reinforcement seat 2 and the second reinforcement seat 3, and a mounting hole 10 is opened in the middle of the top of the fixing plate 9, and the mounting hole 10 is set as a countersunk hole.

During use, the present device can further support and reinforce the first reinforcement seat 2 and the second reinforcement seat 3 through the supporting inclined plates 11, which can improve the stability of the overall support and reinforcement of the shear wall body by the present device.

[0033] Furthermore, three groups of limiting holes 85 are linearly fixedly installed at equal intervals on the outer side of the sleeve frame 81. The positions of the limiting holes 85 correspond to the positions of the fixing screws 84. During the use of the device, the end of the fixing screw 84 can be inserted into the inner side of the limiting hole 85. The limiting holes 85 and the fixing screws 84 are engaged, which can improve the overall stability of the device and the stability of the overall installation and use of the device.

[0034] The working principle of the utility model is as follows:

[0035] When the present embodiment is in use, the first reinforcing seat 2 and the second reinforcing seat 3 are fitted together, and the insert block 4 is inserted into the inner side of the slot 5. At this time, the inclined surface of the limit card block 73 is resisted by the inner wall of the slot 5, so that the limit card block 73 moves inward and compresses the limit spring 72 to shrink into the inside of the square groove 71. When the insert block 4 is inserted into the inside of the slot 5, the limit card block 73 contacts the limit card slot 6, and the limit spring 72 is reset to drive the limit card block 73 to be inserted into the inside of the limit card slot 6. The limit card block 73 and the limit card slot 6 are fitted and limited with each other, so that the first reinforcing seat 2 and the second reinforcing seat 3 can be quickly assembled and installed. Since the outer sides of the first reinforcement seat 2 and the second reinforcement seat 3 are fixedly connected to the supporting inclined plate 11 at equal intervals, the bottom of the supporting inclined plate 11 can be against the ground to assist in supporting and reinforcing the shear wall 1, which can improve the overall stability of the shear wall 1. When the first reinforcement seat 2 and the second reinforcement seat 3 need to be disassembled, the slider 75 can be driven inward by pressing the pressing plate 77. The inward movement of the slider 75 can pull the connecting rod 76 to drive the limiting card block 73 to leave the limiting card slot 6 and retract into the square slot 71. When the insert block 4 loses its limit, the first reinforcement seat 2 and the second reinforcement seat 3 can be quickly separated, making the device as a whole easy to disassemble and overhaul;

[0036] By providing an adjustable support member 8, the device can be used to slide on the inner side of the sleeve frame 81 by adjusting the supporting slide plate 82. By adjusting the supporting slide plate 82 to slide up and down, the total length of the sleeve frame 81 and the supporting slide plate 82 can be assisted to adjust, and then the overall supporting height of the first reinforcement seat 2 and the second reinforcement seat 3 can be extended, which can improve the supporting effect of the device on the shear wall 1. After the height adjustment is completed, the fixing screw 84 is twisted and inserted into the inner side of the limiting hole 85. The fixing screw 84 and the limiting hole 85 are connected and combined with each other to assist in supporting and reinforcing the sleeve frame 81 and the supporting slide plate 82, so that the device as a whole can stably support and reinforce the shear wall 1, and the overall stability of the shear wall 1 can be improved.
