Description

Technical Field

[0001] This utility model relates to the field of armor seam assembly technology, specifically to an armor seam fixing clamp. Background Technology

[0002] Armor joints, commonly found in civil engineering, bridge engineering, road engineering, and large concrete structures, are a structural measure used to address deformation issues such as thermal expansion and contraction, shrinkage and creep, and seismic displacement. They are typically installed between two sections of concrete structure. During the construction and installation of armor joints, clamps are often used to temporarily or permanently fix the components. These clamps secure the various parts of the armor joint in the designed positions, preventing displacement or settlement before concrete pouring. However, existing clamps have significant limitations in their clamping positions and cannot assist in marking lines, making it difficult to maintain a uniform horizontal line when welding reinforcing bars to the outer wall of the armor joint, resulting in poor welding quality. Utility Model Content

[0003] The purpose of this invention is to provide an armor seam fixing clamp to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an armor seam fixing clamp, comprising two legs, the two legs being symmetrically arranged, a crossbeam being fixedly mounted on the upper end of the two legs, a nut being fixedly mounted on the middle of the surface of the crossbeam, a screw being screwed onto the inner wall of the nut, the lower end of the screw penetrating the crossbeam and rotatably connected to a clamping structure, the side end of the clamping structure being connected to one side of one of the legs and the crossbeam through a limiting structure, and a throttle being fixedly mounted on the upper end of the screw.

[0005] Preferably, the clamp structure includes a support, which is rotatably mounted on the lower end of the outer wall of the screw. A limiting groove is fixedly mounted on the lower end of the support. A double-ended stud is rotatably mounted through the inner wall of the limiting groove. A rotating rod is fixedly mounted on one end of the double-ended stud. Two clamping plates are symmetrically screwed to both sides of the outer wall of the double-ended stud. Both clamping plates are fitted into the limiting groove. A clamping block is fixedly mounted on the lower inner side of each of the two clamping plates.

[0006] Preferably, the limiting structure includes a connecting plate, which is fixedly assembled to the side wall of the clamp structure. A base plate is fixedly assembled to the lower end of the side wall of one of the legs. The surface of the base plate is connected to the lower side of the crossbeam via a slide rail. The connecting plate is sleeved on the outer wall of the slide rail, and the connecting plate and the slide rail are in clearance fit.

[0007] Preferably, it also includes two auxiliary support plates, which are respectively fixed to the lower ends of the outer side walls of the two support legs.

[0008] Preferably, hooks for hanging wires are fixedly fitted to the inner sidewalls of both clamps.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the two support legs ensure the overall stability of the equipment. The crossbeam is used to connect the support legs and fix components such as nuts and bolts. With the cooperation of the nuts and bolts, the bolts can be adjusted to move up and down when the handle is turned, thereby determining the longitudinal position of the clamping structure, i.e., the clamping position. Through the action of the clamping structure, the simple mechanical structure can effectively clamp the armor seam, keeping the gap closed when assembling the reinforcing bars. Multiple devices need to be used simultaneously to ensure that multiple clamping structures are on the same horizontal line, which facilitates the marking work on the outer wall of the armor seam. The reinforcing bars are welded according to the marked lines to ensure the processing and assembly effect. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides an armor seam fixing clamp, including two support legs 1, which are symmetrically arranged. A crossbeam 2 is fixedly mounted on the upper end of the two support legs 1. A nut 3 is fixedly mounted on the middle of the surface of the crossbeam 2. A screw rod 4 is screwed to the inner wall of the nut 3. The lower end of the screw rod 4 passes through the crossbeam 2 and is rotatably connected to a clamping structure 6. The side end of the clamping structure 6 is connected to one side of one of the support legs 1 and the crossbeam 2 through a limiting structure 7. A throttle handle 5 is fixedly mounted on the upper end of the screw rod 4.

[0017] Two support legs 1 ensure the overall stability of the equipment. A crossbeam 2 connects the support legs 1 and fixes components such as nuts 3 and screws 4. With the cooperation of nuts 3 and screws 4, the screws 4 can be adjusted to move up and down when the handle 5 is turned, thereby determining the longitudinal position of the clamping structure 6, i.e., the clamping position. Through the function of the clamping structure 6, the simple mechanical structure can effectively clamp the armor seam, keeping the gap closed when assembling the reinforcing bars. Multiple devices need to work together to ensure that multiple clamping structures are on the same horizontal line, which facilitates the marking work on the outer wall of the armor seam. The reinforcing bars are welded according to the marked lines to ensure the processing and assembly effect.

[0018] The clamp structure 6 includes a support 61, which is rotatably mounted on the lower end of the outer wall of the screw 4. A limiting groove 62 is fixedly mounted on the lower end of the support 61. A double-headed stud 65 is rotatably mounted through the inner wall of the limiting groove 62. A rotating rod 64 is fixedly mounted on one end of the double-headed stud 65. Two clamping plates 63 are symmetrically screwed to both sides of the outer wall of the double-headed stud 65. Both clamping plates 63 are fitted into the limiting groove 62. A clamping block 66 is fixedly mounted on the lower inner side of each of the two clamping plates 63.

[0019] When the clamp structure 6 is needed, first rotate the rotating rod 64 to drive the double-ended stud 65 to rotate. According to the characteristics of the double-ended stud, the threads at both ends are opposite. At this time, the two clamping plates 63 connected to it can be driven to move in opposite directions, thereby driving the clamping block 66 at the lower end to move in opposite directions as well. At this time, adjust the clamping blocks 66 on both sides to move closer together and apply continuous pressure to the armor seam until it is clamped and fixed.

[0020] The limiting structure 7 includes a connecting plate 73, which is fixedly assembled to the side wall of the clamping structure 6. A base plate 71 is fixedly assembled to the lower end of the side wall of one of the legs 1. The surface of the base plate 71 is connected to the lower side of the crossbeam 2 through a slide rail 72. The connecting plate 73 is sleeved on the outer wall of the slide rail 72, and the connecting plate 73 and the slide rail 72 are in clearance fit.

[0021] When the clamping structure 6 is displaced by the screw 4, it will cause the connecting plate 73 at the side end to adhere to the outer wall of the slide rail 72 and maintain a fixed trajectory movement. At the same time, it restricts the clamping structure 6 from rotating with the screw 4, and the base plate 71 ensures the stability of the slide rail 72 assembly.

[0022] It also includes two auxiliary support plates 8, which are respectively fixed to the lower ends of the outer side walls of the two support legs 1.

[0023] Support plate 8 can better ensure the stability of the equipment.

[0024] The inner walls of both clamps 63 are fixedly fitted with hanging hooks 9.

[0025] After multiple devices are aligned to a uniform horizontal line, a uniform auxiliary line can be hung in the hook 9 of each device to facilitate the welding of steel bars on the outer wall of the armor seam.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
