DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, the utility model provides a clamping function expansion joint formwork fixing device, including a formwork template 10, which is formed by splicing a plurality of assembly plates 11, and a plurality of wedge-shaped slide grooves 1101 are provided on the front side of the assembly plate 11, and a wedge block 12 is provided on the left side of the front side of the wedge-shaped slide groove 1101, and the wedge block 12 extends to the left side of the template to the outside. When any two assembly plates 11 are arranged side by side, the wedge block 12 on one of the assembly plates 11 is embedded in the wedge-shaped slide groove 1101 of the other assembly plate 11, and the front side of the formwork template 10 is provided with a guide Device 20, a slider b14 is provided at the front center of the rightmost assembly plate 11 on the formwork template 10, and a slider a13 is provided at the front center of the remaining assembly plates 11. The slider a13 and the slider b14 are movably connected to the guide device 20 respectively. When in use, the size of the final formwork template 10 can be assembled arbitrarily according to the actual measured expansion joint size. At the same time, the rightmost assembly plate 11 is moved to the left through the rotating handle 26 on the guide device 20, so that all the assembly plates 11 are finally tightly combined together to avoid leakage during the subsequent pouring of cement mortar.

[0027] like Figure 2 As shown, the wedge block 12 is threadedly connected to the assembly plate 11. This detachable connection method is convenient for assembly according to the actual length of the expansion joint, which increases the flexibility of the formwork. The length of the wedge block 12 is smaller than the length of the wedge-shaped slide groove 1101. When the wedge block 12 is inserted into another assembly plate 11, it will not conflict with the wedge block 12 at that location.

[0028] In a preferred embodiment, the left side and the right side of the assembly plate 11 are respectively provided with a docking portion a1103 and a docking portion b1104, and the docking portions a1103 and b1104 of any two assembly plates 11 are interlocked with each other. Compared with the flat side edges, this mutually interlocking structure can increase the tightness between the assembly plates 11 and reduce the occurrence of leakage.

[0029] like Figure 5-6As shown, the slider a13 is composed of a base 1301 and a plurality of fixed blocks 1302. The fixed blocks 1302 are arranged on the upper and lower sides of the front side of the base 1301. The fixed blocks 1302 are provided with guide holes 1303 in the length direction. The slider b14 has the same base 1301 and fixed blocks 1302 as the slider a13. A connecting bracket 1401 is arranged on the right side of the base 1301, and a threaded sleeve 1402 is arranged on the left side of the connecting bracket 1401. The base 1301 is arranged at the front center of the assembly plate 11 by bolts.

[0030] like Figure 3-4 As shown, the guide device 20 includes the same support a21 and support b23. The support a21 is arranged on the left side of the front side of the leftmost assembly plate 11 by bolts, and the support b23 is arranged on the right side of the front side of the rightmost assembly plate 11. A screw rod 24 and a guide rod 25 are arranged between the support a21 and the support b23.

[0031] In this embodiment, a movable hole 2102 is arranged near the center on the left side of the support a21, and two fastening holes 2101 are symmetrically arranged around the movable hole 2102. The guide rod 25 has two fastening holes 2101 respectively arranged in the support a21 and the support b23 opposite to each other. The screw rod 24 is arranged in the movable hole 2102 opposite to the support a21 and the support b23, and ball bearings 2103 are arranged on both ends of the screw rod 24 at the movable hole 2102.

[0032] Furthermore, a limit cover 22 is provided on the front side of the support a21 at the movable hole 2102, and a rotating handle 26 is provided at the right end of the right end of the tube support b23 of the screw rod 24. When the staff uses the rotating handle 26, the left end of the screw rod 24 conflicts with the limit cover 22. The limit cover 22 strengthens the stability of the screw rod 24 on the guide device 20, thereby preventing excessive friction between the screw rod 24 and the threaded sleeve 1402 when the screw rod 24 is subjected to force in the length direction, resulting in thread wear and even thread slippage.

[0033] Furthermore, the guide holes 1303 on any slider a13 and slider b14 are respectively coaxial with the guide rod 25, and the threaded sleeve 1402 is threadedly connected to the screw rod 24. When the rotary handle 26 is rotated, the threaded sleeve 1402 on the slider b14 is moved to the left by the screw rod 24, thereby driving the rightmost assembly plate 11 to move to the left, and then collides with the adjacent assembly plate 11, and finally collides with the leftmost assembly plate 11 to form a complete formwork template 10.

[0034] In this embodiment, a plurality of screw holes 1102 are opened on the front side of the assembly plate 11. After the formwork template 10 is assembled, it is set at the expansion joint, and then the fixing screw rod 24 is passed through the shear wall and the screw hole 1102 in turn to finally fix the formwork template 10.

[0035] Specifically, the working principle of the expansion joint formwork fixing device with a clamping function is as follows: according to the size of the expansion joint, a suitable number of assembly plates 11 are selected for assembly, the wedge block 12 is inserted into the wedge-shaped slide groove 1101 on the assembly plate 11, and fixed by bolts. Several assembly plates 11 are divided into three categories. The leftmost assembly plate 11 is provided with a slider a13 and a support a21, the rightmost assembly plate 11 is provided with a slider b14 and a support b23, and several middle assembly plates 11 are provided with a slider a13, a screw rod 24 and a guide rod 25 are provided between the support a21 and the support b23, and the slider a13 and the slider b 14 are respectively slidably connected with the guide rod 25, and the threaded sleeve 1402 on the slider b14 is threadedly connected with the screw 24. By rotating the rotating handle 26, the slider b14 drives the rightmost assembly plate 11 to move to the left, and finally squeezes the middle several assembly plates 11 to the left, finally forming a whole formwork template, and setting it at the expansion joint for fixation. The above structure solves the problem of setting several templates at the expansion joint and then clamping several templates by the clamping structure in the existing expansion joint formwork method. The whole process consumes a lot of manpower and time, which increases the complexity and difficulty of construction.

[0036] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
