[0002] In civil engineering, expansion joints are an important structural measure used to cope with deformation of buildings or structures caused by temperature changes, foundation settlement, earthquakes and other factors. Expansion joints divide building components above the foundation, such as walls, floor slabs, roofs (except wooden roofs), into two independent parts, so that the building can expand and contract horizontally along the length. In civil engineering, expansion joints are not only part of the structure, but also need to have waterproof functions to prevent moisture from penetrating into the structure and causing problems such as steel corrosion.

[0003] At present, when waterproofing the expansion joints of roads, waterproof boards are mostly used in conjunction with water stop strips to connect to the expansion joints. The waterproof boards are rigid structures and are mostly installed using expansion bolts. On the one hand, the rigid waterproof boards are easily damaged during thermal expansion and contraction. On the other hand, the waterproof boards installed at the expansion joints using expansion bolts are not easy to be quickly disassembled and replaced. Therefore, we propose a waterproof structure for civil engineering expansion joints. Utility Model Content

[0033] Example 1

[0034] See also Figure 1-Figure 4 As shown, the utility model provides a technical solution: a civil engineering expansion joint waterproof structure, comprising a first waterproof plate 1 and an elastic connector 5, the first waterproof plate 1 is arranged above the expansion joint, and is used to block the expansion joint from above, the upper end surface of the first waterproof plate 1 has arc-shaped surfaces 2 at both ends, and the arrangement of the arc-shaped surfaces 2 can reduce obstruction and increase safety when a vehicle passes through, the lower end surfaces of the first waterproof plate 1 and the second waterproof plate 8 are both provided with waterstops 3, and the first waterproof plate 1 and the second waterproof plate 8 are fitted with independent parts on both sides of the expansion joint through the waterstops 3 to prevent rainwater from entering the expansion joint, the elastic connector 5 It is arranged in the expansion joint, and the elastic connector 5 includes two fixed plates 51, which are symmetrically fixed to the inner wall of the expansion joint. The first connecting plate 52 is vertically connected to the fixed plate 51 on one side, and the second connecting plate 53 is vertically connected to the fixed plate 51 on the other side. The fourth connecting plate 56 is vertically fixed to the upper end face of the first connecting plate 52, and the third connecting plate 55 is vertically fixed to the lower end face of the second connecting plate 53. A first spring 54 is connected between the third connecting plate 55 and the fourth connecting plate 56. The elastic connector 5 cooperates with the telescopic parts of the independent parts on both sides of the expansion joint to move.

[0035] See Figure 1 as well as Figure 4-Figure 5 As shown, the civil engineering expansion joint waterproof structure also includes a second waterproof plate 8, a first mounting plate 6 and a second mounting plate 7. The second waterproof plate 8 is fitted with the first waterproof plate 1 and is arranged on one side below it, and the first waterproof plate 1 and the second waterproof plate 8 are both movable to cope with changes due to thermal expansion and contraction. One end of the first mounting plate 6 is connected to the elastic connector 5, and the specific connection method can be welding. The other end of the first mounting plate 6 is detachably connected to the first waterproof plate 1, and the bottom of the second mounting plate 7 is fixed to the elastic connector 5, and the upper end is detachably connected to the second waterproof plate 8. Specifically, mounting grooves 9 are provided on the lower end surfaces of the first waterproof plate 1 and the second waterproof plate 8. The tops of the first mounting plate 6 and the second mounting plate 7 can be inserted into the corresponding mounting grooves 9, and the first mounting plate 6 is arranged between the first connecting plate 52 and the first waterproof plate 1, and the second mounting plate 7 is arranged between the second connecting plate 53 and the second waterproof plate 8.

[0036] Secondly, see Figure 4 and Figure 5 As shown, the lower end surfaces of the first waterproof board 1 and the second waterproof board 8 are both provided with a lower convex portion, the lower convex portion on the first waterproof board 1 is connected to the guide rod 10, and the lower convex portion on the first waterproof board 1 is provided with a guide groove 14 that cooperates with the guide rod 10. The linear movement of the guide rod 10 in the guide groove 14 can ensure the stability of the movement of the first waterproof board 1 and the second waterproof board 8.

[0037] During thermal expansion, when the independent parts on both sides of the expansion joint expand, the two fixed plates 51 approach each other. At this time, the third connecting plate 55 and the fourth connecting plate 56 approach each other, and the first spring 54 is compressed, which plays a certain buffering role, can reduce the change of the expansion joint and ensure the waterproof effect.

[0038] In addition, when actually installing the waterproof structure, the two fixing plates 51 are symmetrically fixed on both sides of the expansion joint, the installation of the elastic connector 5 is completed first, and then the first waterproof plate 1 and the second waterproof plate 8 can be combined together, and finally the first waterproof plate 1 is lowered for installation, so that the top ends of the first mounting plate 6 and the second mounting plate 7 are inserted into the corresponding mounting grooves 9, and the first waterproof plate 1 and the second waterproof plate 8 are installed and positioned.

[0039] Also, see Figure 5 、 Figure 6 and Figure 7 As shown, the civil engineering expansion joint waterproof structure also includes a limiting structure 13, which is arranged on the first waterproof board 1 and is used to limit the upward movement of the first waterproof board 1 after the first mounting plate 6 is connected to the first waterproof board 1, so as to ensure that the first waterproof board 1 and the second waterproof board 8 can always fit the upper end surfaces of the independent parts on both sides of the expansion joint.

[0040] The limiting structure 13 includes a vertical plate 131 and a limiting rod 132. A groove 11 is provided at the upper end of the first waterproof plate 1. The groove 11 is connected to the corresponding installation groove 9, and the length and width of the groove 11 are both greater than the length of the installation groove 9, so that the groove 11 can be installed with the limiting structure 13. The vertical plate 131 is sleeved on the limiting rod 132. A limiting block 137 is provided at the top of the limiting rod 132. A grip strip 133 is installed at the rear end of the limiting block 137. A limiting groove 15 is provided at the upper end of the side wall of the first mounting plate 6. The end of the limiting rod 132 matches the limiting groove 15. When the limiting rod 132 is embedded in the limiting groove 15, the first mounting plate 6 is limited.

[0041] In one embodiment, a stopper 136 is provided at the top end of the limiting rod 132 , and a limiting block 137 is installed at the rear end of the stopper 136 .

[0042] The length of the vertical plate 131 is smaller than the length and width of the groove 11, and the width of the vertical plate 131 is smaller than the depth of the groove 11. A protruding ring 134 is provided on the limiting rod 132, and the vertical plate 131 is located between the protruding ring 134 and the limiting block 137. A second spring 135 is installed between the vertical plate 131 and the protruding ring 134, and the second spring 135 is wound around the limiting rod 132.

[0044] When the grip bar 133 is in use, it can be rotated to face vertically upwards to facilitate force application. After use, the grip bar 133 can be rotated to the horizontal direction so that the grip bar 133 is in the groove 11.

[0045] When the grip bar 133 is pulled outward to release the obstruction of the limit rod 132, the second spring 135 is in a compressed state. After the top of the first mounting plate 6 is embedded in the mounting groove 9, the grip bar 133 is released. During the process of the second spring 135 returning to its original state, the end of the limit rod 132 can be embedded in the limit groove 15, which can improve the stability in the limited state.

[0046] In addition, a sealing block 4 is embedded in the groove 11, and sealing gaskets 12 are provided on all four sides of the sealing block 4. After the first waterproof board 1 is installed, the sealing block 4 with sealing gaskets 12 on all four sides can be inserted into the groove 11 to seal the groove 11 to prevent rainwater from entering the groove 11. A clamping groove is provided on the upper end surface of the sealing block 4, which is convenient for applying force to clamp out the sealing block 4 when taking it out.
