Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and specifically relates to a temporary support and reinforcement structure for bridge construction. Background Technique

[0002] A bridge is a building structure on which people or vehicles can move on its surface, usually erected above a river.

[0003] During the construction of existing bridges, some auxiliary support frameworks are usually required to support and fix the bridge being constructed, so as to reduce the shaking of the bridge during construction.

[0004] It has been found through long-term use and observation of the existing support structure that when building and disassembling the auxiliary support device, due to the use of brick-concrete structure, it is extremely cumbersome. When the bridge of a designated bridge section is completed, it is extremely inconvenient to disassemble and reassemble the auxiliary support structure.

[0005] Therefore, the utility model provides a temporary support and reinforcement structure for bridge construction. Content of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique.

[0007] The technical solution adopted by the utility model to solve its technical problems is as follows: A temporary support and reinforcement structure for bridge construction according to the utility model includes four vertical rods; the four vertical rods are arranged in a pairwise symmetric manner; a cushion block is fixedly connected to the top of each vertical rod; a first fastener is fixedly connected to the top of the cushion block; a clamping member is fixedly connected to the top of the first fastener; a plurality of support plates are fixedly connected to the middle of the four vertical rods; two first fixing members are fixedly connected to the middle of the support plate; the two first fixing members are symmetrically arranged and are in contact with the side wall of the vertical rod; a second fastener is fixedly connected to the bottom of each of the four vertical rods; a base plate is fixedly connected to the bottom of the second fastener; a plurality of groups of reinforcing ribs are fixedly connected to the middle of the two groups of vertical rods; each group of reinforcing ribs is arranged in a cross shape. Through the above structure, on the one hand, the bridge can be temporarily supported during the bridge construction stage, and on the other hand, by quickly disassembling and installing the device, the situation of difficult disassembly and handling caused by building the support structure during the bridge construction stage can be reduced.

[0008] Preferably, connecting pieces are fixedly connected to the side walls of two adjacent cushion blocks; a transverse cylinder is fixedly connected to the top of the connecting piece; two groups of sliding grooves are formed inside the transverse cylinder; the two groups of sliding grooves are symmetrically arranged; pull rods are fixedly connected to the middle parts of the two groups of sliding grooves; the two pull rods are symmetrically arranged; sliders are slidably connected to the middle parts of the two groups of sliding grooves; a pull rod is fixedly connected to the middle of the two sliders; the pull rod is in sliding fit with the transverse cylinder; a second fixing piece is fixedly connected to the end of the pull rod; the second fixing piece is arranged in a bent shape; blocking pieces are fixedly connected to both ends of the transverse cylinder; the pull rod penetrates through the blocking piece. With the above structure, the fixing and supporting of both ends of the bridge can be realized, thereby reducing the situation that the supporting force is insufficient due to only supporting the bridge from the bottom, which affects the bridge construction.

[0009] Preferably, a clamping groove is formed in the side wall of the slider; a plurality of brush hairs are detachably installed inside the clamping groove; the plurality of brush hairs are all arranged in a bent shape, and the ends are in contact with the top of the sliding groove. With the above structure, by reducing the excessive dust or impurities carried inside the sliding groove, the situation that the sliding of the slider is affected is reduced.

[0010] Preferably, a baffle is fixedly connected to the end of each of the two transverse cylinders; the baffle is conical in shape, and the end is in contact with the middle of the pull rod. With the above structure, the situation that the support or fixation is unstable due to the sliding between the cushion plate and the ground is reduced. At the same time, the situation that the ground carries small stones to cause grooves at the bottom of the cushion plate is also reduced.

[0011] Preferably, anti-slip pads are fixedly connected to the bottoms of the two groups of cushion plates; the size of the anti-slip pad is the same as the size of the bottom of the cushion plate. With the above structure, the fixing and limiting of the bridge by the second fixing piece can be made more firm, thereby reducing the situation that the second fixing piece is not firmly fixed.

[0012] Preferably, friction pads are fixedly connected to the middle parts of the two groups of second fixing pieces; the friction pads are located at the positions of the second fixing pieces close to the ends. With the above structure, the situation that the support or fixation is unstable due to the sliding between the cushion plate and the ground is reduced. At the same time, the situation that the ground carries small stones to cause grooves at the bottom of the cushion plate is also reduced.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. For the temporary support and reinforcement structure for bridge construction of the present utility model, on the one hand, it can temporarily support the bridge during the bridge construction stage, and on the other hand, by quickly disassembling and installing the device, the situation that it is difficult to disassemble and carry during the bridge construction stage due to the erection of the support structure is reduced.

[0015] 2. The temporary support and reinforcement structure for bridge construction described in the present utility model reduces the situation that occurs during bridge construction where the support strength is insufficient due to only supporting the bridge from the bottom by fixing and supporting both ends of the bridge.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0025] Such as Figures 1 to 6As shown in the figure, a temporary support and reinforcement structure for bridge construction according to an embodiment of the present utility model includes four vertical rods 1; the four vertical rods 1 are arranged in a pairwise symmetric manner; a cushion block 14 is fixedly connected to the top of each vertical rod 1; a first fastener 15 is fixedly connected to the top of the cushion block 14; a clamping member 16 is fixedly connected to the top of the first fastener 15; a plurality of support plates 12 are fixedly connected to the middle of the four vertical rods 1; two first fixing members 13 are fixedly connected to the middle of the support plate 12; the two first fixing members 13 are symmetrically arranged and are in contact with the side wall of the vertical rod 1; a second fastener 18 is fixedly connected to the bottom of the four vertical rods 1; a backing plate 19 is fixedly connected to the bottom of the second fastener 18; a plurality of groups of reinforcing ribs 17 are fixedly connected to the middle of the two groups of vertical rods 1; each group of reinforcing ribs 17 is arranged in a cross shape; during operation, during the bridge construction stage, the device is placed at a designated position. At this time, the clamping member 16 is in contact with the bottom of the bridge. By installing a plurality of such devices, the bottom of the bridge can be supported and fixed during the bridge construction process. Since the device uses a large number of bolt structures, after the bridge in the designated bridge section is constructed, the device can be quickly disassembled and then re-erected in the remaining bridge sections. Through the above structure, on the one hand, the bridge can be temporarily supported during the bridge construction stage, and on the other hand, by quickly disassembling and installing the device, the situation of difficult disassembly and handling caused by the construction of the support structure during the bridge construction stage can be reduced.

[0026] As Figures 3 to 6 shown, a connecting member 2 is fixedly connected to the side walls of two adjacent cushion blocks 14; a transverse cylinder 21 is fixedly connected to the top of the connecting member 2; two groups of sliding grooves 24 are formed inside the transverse cylinder 21; the two groups of sliding grooves 24 are symmetrically arranged; a pull rod 22 is fixedly connected to the middle of each of the two groups of sliding grooves 24; the two pull rods 22 are symmetrically arranged; sliding blocks 25 are slidably connected to the middle of each of the two groups of sliding grooves 24; a pull rod 22 is fixedly connected to the middle of the two sliding blocks 25; the pull rod 22 is in sliding fit with the transverse cylinder 21; a second fixing member 23 is fixedly connected to the end of the pull rod 22; the second fixing member 23 is arranged in a bent shape; blocking members 26 are fixedly connected to both ends of the transverse cylinder 21; the pull rod 22 passes through the blocking member 26. During operation, as the vertical rod 1 is erected, the transverse cylinder 21 will also be installed at a designated position. At this time, by pulling the second fixing member 23, as the second fixing member 23 is pulled, the second fixing member 23 will drive the pull rod 22 to drive the sliding block 25 to slide inside the transverse cylinder 21. When the two pull rods 22 are pulled to a designated position, that is, at both ends of the bridge, the second fixing member 23 can be released at this time. At this time, the end of the second fixing member 23 will be in contact with the end of the bridge. Through the above structure, the fixing and support of both ends of the bridge can be realized, thereby reducing the situation that the support strength is insufficient due to only supporting the bridge from the bottom, which affects the bridge construction.

[0027] As Figure 6 shown, a clamping groove 3 is formed in the side wall of the slider 25; a plurality of brush hairs 31 are detachably installed inside the clamping groove 3; the plurality of brush hairs 31 are all bent, and the ends thereof are in contact with the top of the sliding groove 24. During operation, as the second fixing member 23 is pulled, at this time the pull rod 22 will be synchronously pulled, and the slider 25 will be driven to slide inside the sliding groove 24. At this time, as the slider 25 slides, a plurality of brush hairs 31 can be driven to continuously slide, and the top of the sliding groove 24 can be cleaned. Since bridge construction is carried out outdoors and is accompanied by a large amount of smoke and dust, at this time, the sliding groove 24 is cleaned by the brush hairs 31, so that the situation that too much dust or impurities accumulate inside the sliding groove 24 and affect the sliding of the slider 25 can be reduced. Through the above structure, by reducing the excessive dust or impurities carried inside the sliding groove 24, the situation that affects the sliding of the slider 25 can be reduced.

[0028] As Figure 4 shown, a retaining piece 4 is fixedly connected to the end of each of the two transverse cylinders 21; the retaining piece 4 is conical, and the end thereof is in contact with the middle of the pull rod 22. During operation, to temporarily support and fix the bridge, the device needs to be installed at a designated position. At this time, the backing plate 19 will be in contact with the ground. At this time, by providing the anti-slip pad 5, the friction between the bottom of the backing plate 19 and the ground can be increased. Through the above structure, the situation that the backing plate 19 slides relative to the ground, resulting in unstable support or fixation, is reduced. At the same time, the situation that small stones carried by the ground cause grooves in the bottom of the backing plate 19 is also reduced.

[0029] As Figure 3 shown, anti-slip pads 5 are fixedly connected to the bottoms of the two groups of backing plates 19; the size of the anti-slip pads 5 is the same as the size of the bottoms of the backing plates 19. During operation, as the second fixing member 23 is pulled, at this time the second fixing member 23 will be in contact with both sides of the bridge and fix both sides of the bridge. At this time, by installing a friction pad 6 in the middle of the second fixing member 23, the friction pad 6 with greater friction can be in direct contact with both ends of the bridge. Through the above structure, the fixing and limiting of the second fixing member 23 to the bridge can be made more firm, thereby reducing the situation that the second fixing member 23 is not firmly fixed.

[0030] As Figure 5As shown, friction pads 6 are fixedly connected to the middle parts of the two groups of the second fixing members 23; the friction pads 6 are located at positions of the second fixing members 23 close to the ends. During operation, to temporarily support and fix the bridge, the device needs to be installed at a designated position. At this time, the backing plate 19 will come into contact with the ground. By providing the friction pads 6, the friction between the bottom of the backing plate 19 and the ground can be increased. Through the above structure, the situation where the backing plate 19 slides relative to the ground, resulting in unstable support or fixation, is reduced. At the same time, the situation where the ground carries small stones and causes grooves on the bottom of the backing plate 19 is also reduced.

[0031] As Figure 6 shown, the brush 31 is flexibly arranged. Through the above structure, fine dust can be cleaned, and the situation of scratching the chute 24 is reduced.

[0032] During operation, at the bridge construction stage, place the device at the designated position. At this time, the clamping member 16 contacts the bottom of the bridge. By installing multiple such devices, it is possible to support and fix the bottom of the bridge during the bridge construction process. Since this device uses a large number of bolt structures, after the bridge in the designated section is constructed, the device can be quickly disassembled and rebuilt in the remaining sections. As the vertical rod 1 is erected, the horizontal cylinder 21 will also be installed at the designated position. At this time, by pulling the second fixing member 23, as the second fixing member 23 is pulled, the second fixing member 23 will drive the pull rod 22, which will drive the slider 25 to slide inside the horizontal cylinder 21. When the two pull rods 22 are pulled to the designated positions, that is, the two ends of the bridge, the second fixing member 23 can be released at this time. At this time, the end of the second fixing member 23 will contact the end of the bridge. As the second fixing member 23 is pulled, the pull rod 22 will be synchronously pulled and drive the slider 25 to slide inside the chute 24. At this time, as the slider 25 slides, it can drive multiple brushes 31 to continuously slide and clean the top of the chute 24. Since bridge construction is carried out outdoors and is accompanied by a large amount of dust and smoke, by cleaning the chute 24 with the brushes 31, it is possible to reduce the accumulation of too much dust or impurities inside the chute 24, which may affect the sliding of the slider 25. To achieve the temporary support and fixation of the bridge, the device needs to be installed at the designated position. At this time, the backing plate 19 will contact the ground. By setting the anti-slip pad 5, the friction between the bottom of the backing plate 19 and the ground can be increased. As the second fixing member 23 is pulled, the second fixing member 23 will contact the two sides of the bridge and fix the two sides of the bridge. At this time, by installing the friction pad 6 in the middle of the second fixing member 23, the friction pad 6 with greater friction can directly contact the two ends of the bridge. To achieve the temporary support and fixation of the bridge, the device needs to be installed at the designated position. At this time, the backing plate 19 will contact the ground. By setting the friction pad 6, the friction between the bottom of the backing plate 19 and the ground can be increased.
