DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0022] When implementing: Figure 1-5 As shown, a set of cast-in-place support system for bridge pier cap beams comprises: a template 1, wherein two groups of hoop half rings 101 are arranged at the bottom of the template 1, and the number of the two groups of hoop half rings 101 is two, and the surface of the hoop half ring 101 is provided with two connecting parts 102 which are symmetrically distributed, and the surface of the connecting part 102 is provided with two through holes 105, and a screw rod 103 is arranged on one side of the connecting part 102, and nuts 104 are arranged at both ends of the screw rod 103; a fastening mechanism 2, wherein the fastening mechanism 2 comprises a limiting component 21 and an auxiliary component 22, wherein the limiting component 21 is arranged on the surface of the connecting part 102, and the auxiliary component 22 is arranged inside the connecting part 102; wherein the limiting component 21 comprises a plurality of limiting grooves 2101 which are arranged on the surface of the nut 104, and the plurality of limiting grooves 2101 are distributed in a ring shape with the nut 104 as the center, and a side wall of the limiting groove 2101 is arranged in an inclined surface;

[0023] After the two clamp half rings 101 are butt-jointed, the through holes 105 of the connecting parts 102 are connected, and the screw rod 103 is passed through the connected through holes 105 and fastened with the nut 104 to fix the two clamp half rings 101 on the bridge pillars, so as to facilitate the installation of the template 1.

[0024] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the limiting assembly 21 also includes a connecting rod 2106 fixedly connected to the surface of the connecting portion 102, the surface of the connecting rod 2106 is rotatably connected to a connecting block 2103, the other end of the connecting block 2103 is fixedly connected to a rotating plate 2102, the surface of the rotating plate 2102 is fixedly connected to a limiting plate 2104, the other end of the limiting plate 2104 extends to the inside of the adjacent limiting groove 2101, the inner wall of the connecting block 2103 is fixedly connected to a clockwork spring 2105, the other end of the clockwork spring 2105 is fixedly connected to the surface of the connecting rod 2106;

[0025] In the process of fastening the two butted hoop half rings 101 with the rotating nut 104, the limiting plate 2104 can be inserted into the limiting groove 2101. When the nut 104 rotates and moves toward the hoop half ring 101, the inclined surface of the limiting groove 2101 can squeeze the limiting plate 2104 to make it rotate around the connecting rod 2106 through the connecting block 2103, which will not affect the rotation of the nut 104. When the nut 104 rotates in the opposite direction, it can be blocked by the limiting plate 2104 under the action of the inner wall on the other side of the limiting groove 2101, so as to avoid its reverse rotation affecting the fastening effect of the nut 104, and effectively prevent the situation that the nut 104 is loosened and reversed due to vibration during the vibrating process after the pouring is completed, affecting the supporting effect.

[0026] The spring 2105 is provided to maintain the normal positions of the connecting block 2103 and the rotating plate 2102, thereby ensuring that the limiting plate 2104 is always located inside the limiting groove 2101 under normal conditions.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the auxiliary component 22 includes a connecting ring 2201 fixedly connected to one end of the nut 104, a groove 2202 is provided at one end of the connecting ring 2201 away from the nut 104, and the connecting ring 2201 is slidably connected to the surface of the screw 103. The auxiliary component 22 also includes a sealing block 2203 arranged on the surface of the connecting portion 102, the sealing block 2203 is coaxially arranged with the adjacent through hole 105, one end of the sealing block 2203 penetrates into the interior of the connecting portion 102 and is slidably connected to the inner wall of the connecting portion 102, the sealing block 2203 matches the groove 2202, a spring 2204 is fixedly connected to the inner wall of the sealing block 2203, and the other end of the spring 2204 penetrates the sealing block 2203 and is fixedly connected to the inner wall of the connecting portion 102;

[0028] When the nut 104 is installed in place, the sealing block 2203 can be inserted into the interior of the groove 2202 under the action of the spring 2204, so as to achieve the effect of sealing the gap between the connecting ring 2201 and the connecting part 102, and prevent rainwater from entering the interior of the through hole 105 from there and causing rust on the screw 103, so as to facilitate subsequent disassembly work, and effectively avoid the problem of rust on the screw 103 that is inconvenient for subsequent disassembly. At the same time, the setting of the spring 2204 can make the sealing block 2203 fit tightly against the interior of the groove 2202, thereby improving the sealing effect.

[0029] When the utility model is in use, the two clamp half rings 101 are connected to each other, and the through holes 105 of the connecting parts 102 are connected. The screw rod 103 is passed through the connected through hole 105 and fastened by the nut 104 to fix the two clamp half rings 101 on the bridge pillars, so as to facilitate the installation of the formwork 1. During this process, the limit component 21 can prevent the vibration during the vibration process after the pouring is completed, which causes the nut 104 to loosen and reverse, affecting the supporting effect. At the same time, under the action of the auxiliary component 22, rainwater can be prevented from entering the inside of the through hole 105 to cause rust of the screw rod 103, so as to facilitate the subsequent disassembly work, and effectively avoid the problem of rust of the screw rod 103 that is inconvenient for subsequent disassembly.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
