Technical Field

[0001] The present application relates to the technical field of road widening, and in particular to a road widening connection structure. Background Art

[0002] With the continuous development of my country's economy and society, the original road facilities can no longer meet the increasing traffic flow requirements. Compared with the construction of new expressways, widening and renovating the original roads is more in line with my country's national conditions. Therefore, widening on the basis of existing roads is the main method of road traffic renovation at present.

[0003] In order to improve construction efficiency, prefabricated parts are often used in widening and reconstruction. Currently, most of the existing prefabricated parts are one-piece molding structures, and the width of each construction is different, so many specifications of prefabricated parts are required, which has the defect of low applicability of prefabricated structures.

The two fixing seats 111 are arranged opposite to each other, and a through hole 1111 is opened on the surface of the fixing seat 111. The steel cage 112 is fixed between the two fixing seats 111. Multiple widening modules 11 are stacked in a vertical direction to form a widening unit 1, and the multiple widening units 1 are arranged in an array.

[0038] refer to Figure 1 and Figure 2 Two longitudinal connection components 2 are arranged between two adjacent widening modules 11 in the same widening unit 1. The two longitudinal connection components 2 are respectively arranged on both sides of the widening module 11. The longitudinal connection components 2 include a connecting seat 21. A mounting groove 1112 for accommodating the connecting seat 21 is opened on the fixing seat 111. A sliding groove 211 is opened through the surface of the connecting seat 21 facing the widening module 11, and the sliding groove 211 is opened in the vertical direction.

Threads are provided at both ends of the bidirectional lead screw 213. The rotation directions of the two sections of the threads are opposite. Two slide plates 212 are threadedly connected to the bidirectional lead screw 213. The two slide plates 212 are respectively arranged on the two sections of the threads. The slide plates 212 are slidably adapted to the slide groove 211.

[0040] refer to Figure 2The connecting seat 21 is fixedly connected with a guide rod 214 in the slide groove 211 , and the guide rod 214 passes through the slide plate 212 and is slidably fitted therebetween.

[0041] refer to Figure 2 The longitudinal connection component 2 also includes a clamping plate 22, the number of which is the same as the number of the skateboards 212 and corresponds one to one. One side of the clamping plate 22 is fixed to the skateboard 212, and a clamping groove 1113 for accommodating the clamping plate 22 is provided on the fixing seat 111. The inner thread of the clamping plate 22 is connected with a reinforcing bolt 4, and the reinforcing bolt 4 passes through the clamping plate 22 and is threadedly connected to the inner wall of the fixing seat 111 at the clamping groove 1113.

[0042] After placing the connecting seat 21 into the two vertically aligned mounting grooves 1112, the staff rotates the bidirectional lead screw 213, and the bidirectional lead screw 213 drives the slide plate 212 to slide along the guide rod 214 in the slide groove 211.

The side wall of the connecting plate 31 is provided with a slot 311 that is adapted to be engaged with the block 1116. Both ends of the connecting plate 31 are provided with a through slot 312. A reinforcing plate 5 is arranged in two through slots 312 that are aligned in different rows. The connecting bolt 32 is threadedly connected in the fixing seat 111. One end of the connecting bolt 32 extends into the through slot 312. The reinforcing plate 5 and the connecting plate 31 are both threadedly connected with the connecting bolt 32.

[0047] Insert the connecting plate 31 into the two aligned connecting grooves 1114, and the connecting plate 31 squeezes the block 1116 into the cavity 1115 until the block 1116 is aligned with the slot 311, and the spring 1117 releases the elastic force to push the block 1116 into the slot 311, thereby inserting the connecting plate 31 to a suitable position, and then tightening the connecting bolts 32 to fix the connecting plate 31 and the fixing seat 111. Then the staff aligns the widening units 1 of different rows, and then inserts the reinforcing plate 5 into the two aligned through grooves 312, and finally tightens the reinforcing plate 5 and the connecting plate 31 by tightening the connecting bolts 32.
