Description

Technical Field

[0001] The invention relates to the technical field of civil engineering protective equipment, and more particularly to a civil engineering expansion joint waterproof structure. Background Art

[0002] An expansion joint is a structural joint set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure due to climate and temperature changes (thermal expansion and contraction). An expansion joint divides the building components above the foundation, such as walls, floors, roofs (except wooden roofs), into two independent parts, so that the building or structure can expand and contract horizontally along the length direction.

[0003] The existing civil engineering expansion joint waterproof structure includes two groups of building bodies, an expansion joint exists between the two groups of building bodies, two groups of installation grooves are respectively arranged on the right top of the building body located on the left and the left top of the building body located on the right, and also includes steel plates, and the left and right sides of the steel plates are respectively fixed in the two groups of installation grooves; when the existing civil engineering expansion joint waterproof structure is used, the expansion joint is sealed by the steel plate, and the expansion joint is waterproofed by the steel plate; it is found in the use of the existing civil engineering expansion joint waterproof structure that the steel plate can play a waterproof protection role in a short time, but after long-term use, due to the continuous changes in climate, the width of the expansion joint will expand and contract, resulting in a decrease in the stability of the connection between the steel plate and the building body and even cracks, thereby causing the steel plate to lose its waterproof effect.

A pressing plate 13 is provided inwardly at the middle position of the inner side of the fixed plate 4 on the other side of the expansion joint. The contact position of the pressing plate 13 and the two elastic opening and closing plates 12 is processed into an arc surface and the pressing plate 13 is pressed or squeezed out from the middle position of the two elastic opening and closing plates 12. The shrinkage joint is covered with symmetrically mutually embedded toothed steel plates 1, and the outer side surfaces of the non-mutually embedded ends of the toothed steel plates 1 are provided with a plurality of laterally outward anchoring ribs 2, wherein each anchoring rib 2 is provided with a stainless steel slide plate 3 on one side, and the stainless steel slide plates 3 are welded and fixed to the toothed steel plates 1. The mounting seats 7 are pre-buried in the concrete casting layer 5 through the wall bolts 16.

[0020] In actual use, according to Figure 1 The structure shown installs the waterproof structure of the present application in the expansion joint. When a small amount of water flows into the toothed steel plate 1, it is first blocked by the rubber waterproof plate 8 and air-dried after a certain period of time. When the water flow is large, part of the water flows out of the rubber waterproof plate 8, and the seeped water flows along the V-shaped mounting groove 9 to the inside of the recessed through hole in the middle of the V-shaped mounting groove 9, and then enters the water collecting tube 10 to be collected. Part of the water flow will be consumed during the flow, and finally the collected water flow can be air-dried and stored in the water collecting tube 10. The water collecting tube 10 can be taken out regularly to dump the accumulated water inside it. When the expansion joint undergoes horizontal displacement, the pressing plate 13 is pressed into or squeezed into the two elastic opening and closing plates 12, and finally, through the tightening force of the binding belt 11, it is pressed in or squeezed out again to be reset.
