Technical Field
[0001] This utility model relates to the technical field of bridge guardrail reinforcement spacing control device, specifically a simple and efficient bridge guardrail reinforcement spacing control device. Background Technology
[0002] In bridge railing construction, precise control of the rebar spacing is crucial to ensuring the quality and structural safety of the railing. It is one of the key factors in ensuring the quality and structural safety of the railing.
[0003] However, in traditional construction methods, the control of rebar spacing largely relies on manual measurement and experience. This method has many problems: First, manual measurement is inefficient, and frequent measurement operations significantly prolong the construction period; second, manual measurement has poor accuracy and is easily affected by human factors, leading to large measurement errors; furthermore, due to differences in workers' experience levels, the control effect of rebar spacing is difficult to maintain consistently, resulting in inconsistent construction quality. These problems not only affect the overall quality and structural safety of bridge railings but may also lead to increased subsequent maintenance costs.
[0004] Therefore, in order to improve construction efficiency and quality, there is an urgent need for a device that can quickly and accurately control the spacing of steel bars. This device should be able to effectively solve the problems of low efficiency, poor accuracy, and easy error in traditional methods, while ensuring the consistency of construction quality, thereby providing a more reliable guarantee for bridge railing construction. Utility Model Content
[0005] The purpose of this invention is to provide a simple and efficient bridge guardrail reinforcement spacing control device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a base, with a column at the top of the base, an adjusting block slidably connected to the column, steel bar insertion grooves on the outer sides of both ends of the adjusting block, telescopic grooves on both sides of the surface of the adjusting block, a telescopic column elastically connected in the telescopic grooves, a connecting plate connected to the outer side of the telescopic column, and a clamping arc plate connected to the inner ends of the connecting plate via connecting rods.
[0007] Preferably, the column has sliding grooves on both sides, and the adjusting block has sliders on the inner sides of both ends. The sliders are inserted into the sliding grooves on both sides of the column to slide the adjusting block to the column.
[0008] Preferably, springs are provided in the telescopic grooves opened on both sides of the surface of the adjusting block. The inner side of the spring is connected to the inner wall of the telescopic groove, the outer side of the spring is connected to the telescopic column, and the outer side of the telescopic column is connected to the connecting plate. The spring can drive the telescopic column to extend and retract, so that the telescopic column drives the connecting plate to extend and retract synchronously.
[0009] Preferably, the outer sides of both ends of the adjusting block are provided with steel bar insertion slots, and the ends of the steel bars can be inserted into the steel bar insertion slots. The outer side of the adjusting block is provided with multiple sets of insertion interfaces, which are opened on the inner side of the connecting plate. The clamping arc plate connected to the inner side of the connecting plate by the connecting rod is inserted into the adjusting block through the insertion interfaces.
[0010] Preferably, the column has a threaded groove in the middle, and the connecting plate and the adjusting block have through holes in the middle. The through holes in the middle of the connecting plate and the adjusting block are parallel. A fixing bolt is inserted into the point where the through hole and the threaded groove coincide, so that the adjusting block can be slidably fixed on the column.
[0011] Preferably, the column has a scale on both sides of its surface, which can accurately indicate the sliding distance of the adjustment block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention presents a simple and efficient rebar spacing control device for bridge railings. During bridge railing construction, the base is fixed at the predetermined installation point. Then, adjusting blocks are pushed one by one onto the column according to the required rebar spacing. The sliding distance of the adjusting blocks is precisely observed through a scale on the column surface. When the adjusting block reaches the required spacing, a half-section fixing bolt is screwed into the threaded groove coinciding with the through hole of the connecting plate and adjusting block, first fixing the position of the adjusting block on the column. Then, rebars are inserted into the rebar insertion grooves on the outer sides of both ends of the adjusting block. Finally, the fixing bolt is continued to be screwed on until it extends from the back of the adjusting block. The connecting plate is tightened by screwing on the nuts and securing the bolts. Simultaneously, the nuts compress the connecting plate, causing the telescopic column connected to the inner side of the connecting plate to retract into the telescopic groove. This retraction of the connecting plate also causes the clamping arc plates connected to the connecting rods on both sides to insert into the rebar splice slots through the insertion interfaces on both sides of the adjusting block. This clamping arc plates clamp the rebar in the rebar splice slots, fixing the rebar in place. This achieves simple and efficient adjustment of the rebar spacing while simultaneously fixing the rebar, providing a more reliable guarantee for bridge railing construction. Furthermore, both the rebar splice slots and the inner surfaces of the clamping arc plates are equipped with anti-slip textures to prevent the rebar from slipping. Attached Figure Description

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a base 1, a column 2 is provided on the top of the base 1, an adjusting block 6 is slidably connected to the column 2, steel bar insertion grooves 8 are provided on the outer sides of both ends of the adjusting block 6, and telescopic grooves 9 are provided on both sides of the surface of the adjusting block 6. A telescopic column 11 is elastically connected in the telescopic groove 9, a connecting plate 12 is connected to the outer side of the telescopic column 11, and a clamping arc plate 15 is connected to the inner ends of the connecting plate 12 through a connecting rod 14; while the fixing bolt 5 is tightened, the connecting plate 12 is squeezed through the nut, so that the telescopic column 11 connected to the inner side of the connecting plate 12 retracts into the telescopic groove 9.
[0022] The column 2 has sliding grooves 3 on both sides, and sliders 7 are provided on the inner sides of both ends of the adjusting block 6. The sliders 7 are inserted into the sliding grooves 3 on both sides of the column 2, so that the adjusting block 6 and the column 2 are slidably connected. The expansion grooves 9 on both sides of the surface of the adjusting block 6 are provided with springs 10. The inner side of the spring 10 is connected to the inner wall of the expansion groove 9, and the outer side of the spring 10 is connected to the expansion column 11. The outer side of the expansion column 11 is connected to the connecting plate 12. The spring 10 can drive the expansion column 11 to expand and contract, so that the expansion column 11 drives the connecting plate 12 to expand and contract synchronously. When the connecting plate 12 contracts, it drives the clamping arc plate 15 connected to the connecting rods 14 on both sides to be inserted into the steel bar insertion groove 8 through the insertion interface 13 on both sides of the adjusting block 6.
[0023] The adjusting block 6 has rebar insertion slots 8 on both outer sides, and the ends of the rebars can be inserted into the rebar insertion slots 8. The adjusting block 6 has multiple sets of insertion interfaces 13 on its outer side. The insertion interfaces 13 are located on the inner side of the connecting plate 12. The clamping arc plate 15, which is connected to the inner side of the connecting plate 12 by the connecting rod 14, is inserted into the adjusting block 6 through the insertion interfaces 13. The clamping arc plate 15 is inserted into the rebar insertion slots 8 through the insertion interfaces 13 on both sides of the adjusting block 6, so that the clamping arc plate 15 clamps the rebars in the rebar insertion slots 8 and fixes the rebars in the rebar insertion slots 8.
[0024] The column 2 has a threaded groove 16 in the middle, and the connecting plate 12 and the adjusting block 6 have through holes in the middle. The through holes in the middle of the connecting plate 12 and the adjusting block 6 are parallel. A fixing bolt 5 is inserted into the point where the through hole and the threaded groove 16 coincide, which can slide and fix the adjusting block 6 on the column 2. The two sides of the surface of the column 2 are provided with scales 4, which can accurately indicate the sliding distance of the adjusting block 6. The scales 4 on the surface of the column 2 can accurately observe the sliding distance of the adjusting block 6.
[0025] In practical application, during the construction of bridge railings, the base 1 is fixed at the predetermined installation point of the bridge railing. Then, according to the required spacing of the reinforcing bars, the adjusting blocks 6 are pushed one by one to slide on the column 2. The sliding distance of the adjusting blocks 6 is precisely observed through the scale 4 on the surface of the column 2. When the adjusting blocks 6 reach the required spacing distance, half of the fixing bolt 5 is screwed into the threaded groove 16 that coincides with the through hole of the connecting plate 12 and the adjusting block 6 to fix the position of the adjusting blocks 6 on the column 2. Then, the reinforcing bars are inserted into the reinforcing bar insertion grooves 8 opened on the outer sides of both ends of the adjusting blocks 6. Then, the fixing bolt 5 is continued to be screwed on so that the fixing bolt 5 protrudes from the back of the adjusting blocks 6, and the nut is screwed on to fix the bolt. The bolt 5 is tightened, and the nut begins to compress the connecting plate 12, causing the telescopic column 11 connected to the inner side of the connecting plate 12 to retract into the telescopic groove 9. Simultaneously, the retraction of the connecting plate 12 drives the clamping arc plate 15 connected to the connecting rods 14 on both sides to be inserted into the rebar insertion groove 8 through the insertion interfaces 13 on both sides of the adjusting block 6. This clamping arc plate 15 clamps the rebar in the rebar insertion groove 8, fixing the rebar in the rebar insertion groove 8. This achieves simple and efficient adjustment of the rebar spacing while simultaneously fixing the rebar, thus providing a more reliable guarantee for bridge railing construction. Furthermore, the inner surfaces of the rebar insertion groove 8 and the clamping arc plate 15 are both provided with anti-slip textures to prevent the rebar from slipping.
