Technical Field

[0001] The utility model relates to the technical field of underground engineering waterproofing, in particular to a connection joint of a water-stop steel plate. Background Art

[0002] Waterstop steel plates are widely used in the structural construction of underground waterproof projects. Their function is to prevent groundwater from seeping into the underground wall through construction joints under the action of capillary penetration. Generally speaking, waterstop steel plates use 3mm thick cold-rolled plates as the base material, and the cold-rolled plates are bent to both sides along the length direction to form waterstop steel plates.

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0026] The utility model provides a connection joint of a waterstop steel plate, comprising: a steel plate body 100, a limiting member 200 and a clamping block 300; one end of the steel plate body 100 has a recessed portion 110, and after the two steel plate bodies 100 are arranged relative to each other, the recessed portions 110 are symmetrically arranged to form a groove 120; the limiting member 200 is used to limit the positions of the two steel plate bodies 100; the clamping block 300 is installed in the groove 120.

[0027] After limiting the positions of the two steel plate bodies 100 by the limiting member 200, the utility model installs the clamping block 300 in the groove 120 formed by the steel plate body 100, and splices the ends of the two waterstop steel plates, thus solving the problem that welding is required for connecting the traditional waterstop steel plates.

[0028] In one embodiment, the recessed portion 110 is a raised corner groove, and two corner grooves are correspondingly arranged to form a groove 120 for installing the clamping block 300 .

[0029] In one embodiment, the shape of the clamping block 300 is consistent with the shape of the groove 120, so that the clamping block 300 can be clamped tightly and the connection is not easy to loosen.

[0030] Exemplarily, the shapes of the groove 120 and the block 300 are square, circular, etc., which is not limited in the present invention.

[0031] Exemplarily, in order to facilitate connection with the steel plate body 100, the angle of the angle groove at the end opposite to the opening direction of the steel plate is greater than the angle groove at the end in the same direction as the opening direction of the steel plate.

[0032] In one embodiment, a filling layer is provided on the outer wall of the block 300, and the filling layer is a waterproof layer. The block 300 is nailed into the groove 120 formed by splicing two waterproof steel plates to further reinforce the waterproof steel plates and make the splicing of the waterproof steel plates tighter.

[0033] Exemplarily, the waterproof layer is made of a water-stopping material that swells when exposed to water. The waterproof layer swells when exposed to water, further waterproofing it and preventing water from penetrating into the interior through the joints of the steel plates.

[0034] In one embodiment, the limiting member 200 is an L-shaped steel plate groove, one end of which is vertically fixed to one side of the recessed portion 110 , and the other side of the recessed portion 110 is a straight short steel plate 130 .

[0035] Insert the straight short steel plate 130 on one side of the first water-stop steel plate into the L-shaped steel plate groove of the other water-stop steel plate, and at the same time insert the straight short steel plate 130 on one side of the other water-stop steel plate into the L-shaped steel plate groove of the first water-stop steel plate, so that the two water-stop steel plates are parallel. The method of splicing the ends of the two water-stop steel plates by using the outwardly protruding corners of the ends of the water-stop steel plates and the L-shaped cut-off grooves to prevent horizontal movement solves the problem of welding required for connection between traditional water-stop steel plates.

[0036] In one embodiment, the length of a section of the L-shaped steel plate groove parallel to the steel plate body 100 is consistent with the length of the straight short steel plate 130. This allows the straight short steel plate 130 to just rest against the L-shaped steel plate groove to complete the fixation.

[0037] The specific method of use is as follows: move the first waterstop steel plate to the concrete construction joint, spot weld the water-facing and water-receiving surfaces (non-joint positions) of the waterstop steel plate with short steel bars, and fix the waterstop steel plate in the upper, lower, left, and right positions. Move the second waterstop steel plate to the construction joint, insert a straight short steel plate 130 at the end of the waterstop steel plate into the L-shaped steel plate groove at the end of the first waterstop steel plate, and insert the straight short steel plate 130 of the first waterstop steel plate into the L-shaped steel plate groove of the second waterstop steel plate, so that the two waterstop steel plates are parallel. Temporarily fix the second waterstop steel plate, and then nail the block 300 wrapped with water-swellable waterstop material into the groove 120 formed by the two waterstop steel plates being butted. Finally, permanently fix the second waterstop steel plate, and then butt the subsequent waterstop steel plates.

[0038] The utility model adopts a method of splicing the ends of two waterstop steel plates by adopting an outwardly protruding corner at the end of the waterstop steel plate and an L-shaped cut-off groove for preventing horizontal movement, thereby solving the problem that the connection between traditional waterstop steel plates requires welding.

[0039] The utility model uses a method of adjusting the position of the waterstop steel plate by splicing the end corners of two waterstop steel plates to form a groove 120, so that the end of the steel plate can extend deeper into the L-shaped cut-off groove, solving the problem of poor fit of the steel plate connection.

[0040] The utility model adopts the technology of wrapping a circle of water-swelling water-stopping material with a card block 300 and nailing it into the groove 120 formed by splicing two water-stopping steel plates, so as to further reinforce the water-stopping steel plates, make the splicing of the water-stopping steel plates tighter, and further waterproof at the same time, and prevent the infiltration of water from entering the interior through the splicing seams of the steel plates; it solves the problem of fixing with bolts and the like in traditional technologies, and does not damage the integrity of the water-stopping steel plates.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
