Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 6In an embodiment of the utility model, a concrete precast component fixing assembly includes a placement unit 100 and a plurality of clamping units 300.

The bottom surface of the mounting groove is provided with a plurality of anti-slip convex strips 130.

[0025] Specifically, a mounting groove is provided on the top surface of the fixing seat 110, which is mainly used to accommodate the precast concrete parts, and a plurality of anti-slip convex strips 130 are provided on the bottom surface of the mounting groove, which increases the friction between the mounting groove and the precast concrete parts. According to the sizes and shapes of the precast concrete parts, the clamping units 1 300 can be selectively inserted into different square grooves 112, and then the clamping units 1 300 are adjusted so that the precast concrete parts are clamped and fixed by a plurality of clamping units 1 300, and then the precast concrete parts are further clamped by the clamping units 200.

[0026] Embodiment 1

[0027] like Figure 2-3 and Figure 5As shown, in this embodiment, several adjustment modules 140 include rotating columns 141, the outer arc surfaces of several rotating columns 141 are respectively rotatably connected to the inner arc surfaces of several circular slots, the ends of several rotating columns 141 located on the outer side wall of the fixed seat 110 are fixedly connected with knobs 143, and the other ends of several rotating columns 141 are fixedly connected with clamping blocks 142, and the clamping unit 1 300 includes a square sleeve 310, and the bottom surface of the square sleeve 310 is fixedly connected with a plug-in block 311, the outer wall of the square sleeve 310 and the inner wall of the square groove 112 are slidably plugged, and the outer wall of the plug-in block 311 and the slot hole of the guide groove 120 are slidably plugged. The square sleeve 310 is internally rotatably connected with a threaded column 320, and the outer wall of the threaded column 320 is screwed and connected with a sleeve 330, the outer wall of the sleeve 330 and the inner wall of the square sleeve 310 are slidably connected, the end of the sleeve 330 is fixedly connected with a rotating seat 340, the side wall of the rotating seat 340 is rotatably connected with a connecting piece 350, and the side wall of the connecting piece 350 is fixedly connected with a flexible clamping strip 360, and the end of the threaded column 320 close to the adjustment module 140 is provided with a snap-in groove 322, the size of the snap-in groove 322 matches the snap-in block 142, and the end of the threaded column 320 located inside the sleeve 330 is fixedly connected to a limiting block 321.

[0028] In this embodiment, according to the size and shape of the concrete prefabricated parts placed in the installation groove, several clamping units 300 can be selectively installed in several square grooves 112 respectively. During installation, the plug-in block 311 is aligned and plugged with the slot hole of the guide groove 120, and then the end of the square sleeve 310 is plugged into the square groove 112 along the guide groove 120. By providing the plug-in block 311 and the guide groove 120, it is easier to connect the square sleeve 310 with the square groove 112. During this period, the corresponding knob 143 is rotated so that the square sleeve 310 is plugged into the square groove 112 while the clamping groove 322 is also clamped with the clamping block 142. When the installation of several clamping units 300 is completed, the corresponding threaded column 320 is rotated synchronously by rotating the knob 143 clockwise, thereby driving the sleeve 330 outward. The flexible clamp 360 is extended until the side wall of the flexible clamp 360 contacts the outer wall of the concrete. By fixing the limit block 321 at the end of the threaded column 320, the length of the sleeve 330 extending out can be limited to avoid excessive adjustment causing the sleeve 330 to separate from the threaded column 320. The material of the flexible clamp 360 includes but is not limited to rubber, which can not only better fit the surface of the precast concrete part, but also avoid wear on the precast concrete part during the clamping process. Since the connecting member 350 and the rotating seat 340 are rotatably connected, when the surface of the precast concrete part is curved, the connecting member 350 will adaptively rotate and fit when the flexible clamp 360 contacts the surface of the precast concrete part. After the fitting is completed, in order to avoid the subsequent deviation of the flexible clamp 360, the connecting member 350 and the rotating seat 340 can be fixed by tightening the screws.

[0029] like Figure 6As shown, in this embodiment, a second threaded hole 312 is provided on the outer wall of the square sleeve 310 that is inserted into the inner wall of the square groove 112, and a first threaded hole 113 is provided on the top surface positions of the fixing seat 110 corresponding to several second threaded holes 312, and a screw 370 is screwed and connected between the screw 370 and the second threaded hole 312.

[0030] In a specific implementation, in order to prevent the square sleeve 310 from sliding out of the square groove 112 during fixation, thereby affecting the fixation stability, the square sleeve 310 can be fixed on the fixing seat 110 by screwing the screw 370 into the threaded hole 113 and the threaded hole 2 312 .

[0031] Embodiment 2

[0032] like Figure 1 and Figure 4 As shown, in the present embodiment, the two clamping units 200 each include a clamping plate 210, and three threaded rods 211 are fixedly connected at equal distances on the opposite sides of the two clamping plates 210, and the outer walls of the three threaded rods 211 are respectively slidably plugged into the inner walls of the three plug holes 111 on the same side thereof, and the outer walls of the six threaded rods 211 are movably sleeved with a return spring 1 212, and the outer walls of the six threaded rods 211 extending out of the outer wall of the fixed seat 110 are screwed and connected with nuts 213, and a plurality of circular holes are opened at equal distances on the top surfaces of the two clamping plates 210, and a return spring 220 is fixedly connected in the plurality of circular holes, and a pressure plate 221 is fixedly connected to the other ends of the plurality of return springs 220.

[0033] During specific implementation, the precast concrete part is placed in the installation groove, and the nut 213 can be rotated outward, so that the two clamping plates 210 are moved toward each other under the elastic force of the reset spring 1 212, and the end surface of the precast concrete part is clamped. When clamping it, the pressing plate 221 can be pulled upward. When the two clamping plates 210 contact the surface of the precast concrete part, the pulling force on the pressing plate 221 is released, and the pressing plate 221 moves downward under the elastic force of several reset springs 220, thereby clamping the top surface of the precast concrete part, so that the precast concrete part is clamped between the pressing plate 221 and the bottom surface of the installation groove, thereby increasing the fixing strength.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
