Technical Field

The utility model relates to the technical field of bridge construction, in particular to a tool for reinforcing a bridge structure.

Background

The bridge reinforcing technology is one of the most important processes in the bridge maintenance process, and the commonly used bridge reinforcing method is a section enlarging reinforcing method, namely, the bearing area of the enlarged foundation is enlarged by planting bars on the original foundation and pouring concrete on the periphery of the bars. At present before pouring concrete, need to build the supplementary extension board that is used for supporting muddy earth, but bridge reinforcement's supplementary extension board is all comparatively huge, all very difficult keeping the level after building in-process and building the completion, fills up fragment of brick or billet class in the below usually among the prior art, and whatever mode all needs to be repeated continuously to lift up, put down until supplementary extension board level, complex operation, inconvenient regulation.

SUMMERY OF THE UTILITY MODEL

Aiming at the situation, in order to overcome the defects of the prior art, the utility model provides a tool for reinforcing a bridge structure, which effectively solves the problems that an auxiliary support plate which needs to be built in the traditional bridge reinforcing process needs to be kept horizontal by continuously adjusting a cushion block or a wood block, and is complex in operation and inconvenient to adjust.

The technical scheme for solving the problem is that the device comprises a rectangular box with an opening-shaped upper end, two rectangular blocks capable of sliding left and right along the rectangular box are arranged in the rectangular box, a horizontal double-head lead screw is arranged in the rectangular box, the lead screw penetrates through the rectangular blocks, the rectangular blocks are in threaded connection with the lead screw, and the end part of the lead screw is rotatably connected to a side plate of the rectangular box; every rectangle box upper end all has a plurality of vertical risers, and the riser is the wedge, and the riser of both sides is crisscross each other arranges, and there is the cushion of arranging along the fore-and-aft direction rectangle box top, and the cushion up end is the level form, and the cross-section of terminal surface is the ascending V form of opening under the cushion, has the inclined plane on the riser, and the incline direction on the inclined plane on the riser of the left and right sides is opposite, and the terminal surface pastes under the inclined plane on the riser and the cushion.

Furthermore, the lower end of the cushion block is provided with a long strip plate which is arranged along the left-right direction and is positioned in a gap between the vertical plate and the vertical plate.

Further, the inboard of curb plate all seted up the spout around the rectangle box on, the rectangle piece end fixing has protruding piece, protruding piece just can follow the spout horizontal slip in arranging the spout in.

Furthermore, a turntable is coaxially fixed at the end part of the lead screw.

The adjustable horizontal support plate adjusting device is ingenious in structure, can replace the complex process of directly increasing or reducing the cushion blocks in the traditional process, does not need repeated adjustment, can adjust a large and heavy auxiliary support plate to be in a horizontal state by using a simple tool, is convenient and quick, is simple to operate, and is easy to realize.

Detailed Description

The following description will explain embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, the utility model comprises a rectangular box 1 with an open upper end, two rectangular blocks 2 capable of sliding left and right along the rectangular box 1 are arranged in the rectangular box 1, a horizontal double-head screw rod 3 is arranged in the rectangular box 1, the screw rod 3 penetrates through the rectangular blocks 2, the rectangular blocks 2 and the screw rod 3 are connected through threads, and the end part of the screw rod 3 is rotatably connected to a side plate of the rectangular box 1; every 1 upper end of rectangle box all has a plurality of vertical risers 4, and riser 4 is the wedge, and 4 crisscross arrangements of riser of both sides each other have along the cushion 5 that the fore-and-aft direction arranged in the top of

rectangle box

1, and 5 up end of cushion are the level form, and the cross-section of terminal surface is the ascending V form of opening under the cushion 5, has the inclined plane on the riser 4, and the incline direction on the inclined plane on the riser 4 of the left and right sides is opposite, and the terminal surface pastes under the inclined plane on the riser 4 and the cushion 5.

In order to limit the forward and backward movement of the cushion block 5, the lower end of the cushion block 5 is provided with a long strip plate 6, the long strip plate 6 is arranged along the left and right direction, and the long strip plate 6 is positioned in a gap between the vertical plate 4 and the vertical plate 4.

In order to guarantee the horizontal slip of rectangular block 2, rectangular box 1 on the inboard of curb plate around all seted up the spout, 2 end fixing of rectangular block have protruding piece 7, protruding piece 7 is arranged in the spout and can be followed the spout horizontal slip.

In order to rotate the screw rod 3 conveniently, a turntable 8 is coaxially fixed at the end part of the screw rod 3.

And a bearing is arranged between the screw rod 3 and the side plate of the rectangular box 1.

It is worth noting that if the auxiliary support plate is inclined seriously, a small ball which can roll by a wheel or a ball hinge can be arranged at the upper end of the cushion block 5, so that the auxiliary support plate can be ensured to be horizontal, and the auxiliary support plate is prevented from being displaced or misplaced in the horizontal direction.

For convenience of explanation, if the auxiliary support plate needs to be propped upwards, when the device is used, the device is placed at a proper position, then the screw rod 3 is screwed, the screw rod 3 drives the two rectangular blocks 2 to approach each other, the upper ends of the rectangular blocks 2 approach each other, so that the left and right rows of vertical plates 4 approach towards the middle, in the process, the inclined surfaces on the vertical plates 4 at the two sides force the cushion blocks 5 to be propped upwards, and it is worth noting that the cushion blocks 5 only move in the vertical direction until the upper ends of the cushion blocks 5 prop against the auxiliary support plate and keep the auxiliary support plate horizontal; when dismantling, its process is opposite, and is concrete, the reverse rotation lead screw 3, lead screw 3 drive two rectangular blocks 2 and remove to the one side of keeping away from each other, and rectangular block 2 drives about two rows of risers 4 and removes to both sides for cushion 5 moves down, realizes dismantling the function.
