The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0019] The first embodiment of this application is as follows:

[0020] Please refer to Figures 1-4 , Figure 1 which is a schematic diagram of the overall structure of a temporary bridge structure of a steel structure for road and bridge construction in the first embodiment of the present utility model, Figure 2 which is a schematic diagram of the structure of the lapping device in the first embodiment of the present utility model, Figure 3 which is a connection diagram of the abutting frame and the fixing rod in the first embodiment of the present utility model, Figure 4 which is a connection diagram of the bridge slab and the clamping block in the first embodiment of the present utility model.

[0021] The present utility model provides a temporary bridge structure of a steel structure for road and bridge construction, which includes a main pile 101, a bearing platform 102 and a column 103, and further includes a lapping device. The lapping device includes a capping beam 104, a bridge slab 105, a clamping block 106, an abutting frame 107, a fixing rod 108, a locking component and a shockproof component. The shockproof component includes a stop block 110 and a shockproof block 111. The locking component includes a threaded rod 112 and a rotating block 113. Through the foregoing solution, the problem that although the conventional temporary bridge structure of a steel structure for road and bridge construction can achieve disassembly and installation, its design structure is complex, the construction period for installation and disassembly is long, and the workload is large, thus prolonging the total construction period of the road and bridge construction is solved. The foregoing solution can be used in the scenario of rapid lapping of a temporary bridge structure of a steel structure for road and bridge construction, and can also be used to solve the problem of auxiliary support for the bridge slab.

[0022] In this embodiment, through the sliding fit between the clamping block 106 on the bridge slab 105 and the card slot 109 on the capping beam 104, the rapid installation and disassembly of the temporary bridge structure are realized, the workload of the temporary bridge is reduced, and the unnecessary prolongation of the construction period is avoided.

[0023] Among them, the capping beam 104 is fixedly installed on the column 103. A clamping groove 109 is provided on the capping beam 104. The clamping groove 109 penetrates through the capping beam 104 and extends into the interior of the capping beam 104. The clamping block 106 is embedded in the clamping groove 109 and is fixedly connected to the bridge slab 105. The abutting frame 107 penetrates through the clamping groove 109 and abuts against the clamping block 106. The fixing rod 108 is installed on the capping beam 104 through the locking assembly and is fixedly connected to the abutting frame 107. The shockproof assembly is installed on the capping beam 104. The number of capping beams 104 is two groups, and they are distributed at the tops of the columns 103 on both sides. The bottom of the capping beam 104 is of a trapezoidal structure. Two groups of the clamping blocks 106 are welded to both sides of the bottom of the bridge slab 105. The cross-section of the clamping block 106 is of a cross structure and is adapted to the clamping groove 109. The width of the abutting frame 107 is equal to the width of the clamping groove 109. The fixing rod 108 is welded to the abutting frame 107. The fixing rod 108 and the abutting frame 107 form a T-shaped structure and are symmetrically distributed on both sides of the bridge slab 105. Threaded holes are provided on both sides of the fixing rod 108. The locking assembly can fix the positions of the clamping block 106 and the bridge slab 105, and the shockproof assembly can reduce the vibration of the bridge slab 105 on the capping beam 104. During use, through the sliding fit between the clamping block 106 on the bridge slab 105 and the clamping groove 109 on the capping beam 104, the clamping block 106 drives the bridge slab 105 to be installed on the capping beam 104, and the bridge slab 105 is fixed through the locking assembly, thus realizing the rapid installation and disassembly of the temporary bridge structure, reducing the engineering quantity of the temporary bridge, and avoiding unnecessary extension of the construction period.

[0024] Secondly, the stop block 110 is fixedly installed on the capping beam 104; the shockproof block 111 is fixedly installed on the stop block 110 and contacts the bridge slab 105. The number of shockproof assemblies is two groups, and they are distributed on the capping beams 104 on both sides. The stop block 110 is welded to the capping beam 104. The shockproof block 111 is made of rubber material. When the bridge slab 105 vibrates, the shockproof block 111 can buffer the vibration, thereby reducing the vibration of the bridge slab 105 on the capping beam 104.

[0025] Again, the threaded rod 112 passes through the fixed rod 108 and is threadedly connected to the capping beam 104; the rotating block 113 is fixedly installed on the threaded rod 112, and two sets of the locking components are symmetrically arranged on each set of the fixed rods 108. The rotating block 113 is welded to the threaded rod 112. During use, by rotating the rotating block 113, the threaded rod 112 is driven to rotate, so that the threaded rod 112 is screwed into the capping beam 104, thereby achieving the fixing effect of the fixed rod 108.

[0026] In this embodiment, during use, the main pile 101, the bearing platform 102, the column 103 and the capping beam 104 are installed in sequence. Subsequently, the clamping block 106 at the bottom of the bridge slab 105 is aligned with the card slot 109, and the clamping block 106 is slid into the card slot 109 until the side of the bridge slab 105 abuts against the shockproof block 111. At this time, the bridge slab 105 is installed on the capping beam 104. Subsequently, one side of the bridge slab 105 is fixed. The abutting frame 107 is pushed into the card slot 109 so that the abutting frame 107 abuts against the outer clamping block 106. Subsequently, the threaded rod 112 is driven by the rotating block 113 to be screwed into the capping beam 104, so that the fixed rod 108 fixes the clamping block 106 in the card slot 109 through the abutting frame 107. At this time, the bridge slab 105 is completed and fixed. During disassembly, just operate in the reverse order of the above steps. Through the sliding fit between the clamping block 106 on the bridge slab 105 and the card slot 109 on the capping beam 104, the rapid installation and disassembly of the temporary bridge structure are realized, the engineering quantity of the temporary bridge is reduced, and the unnecessary extension of the construction period is avoided.

[0030] Among them, the supporting diagonal rod 201 is installed between the bearing platform 102 and the bridge slab 105 through the connecting member. The number of the auxiliary support components is two groups, and they are symmetrically distributed on both sides of the bridge slab 105.
