Description

Technical Field

[0001] The utility model relates to the technical field of roof waterproof structures, in particular to a novel waterproof structure for construction joints. Background Art

[0002] With the continuous expansion of urban construction, water leakage in roof structures has always been a quality problem in the construction of housing structures. Water leakage at the construction joints of the roof directly affects the subsequent use function, and because water is a flowing liquid, it is even more difficult to find the water leakage point, which makes subsequent remedial construction difficult. Therefore, this problem needs to be solved once and for all during the first construction process. Traditional waterproof structures generally only have one of the buried type or the external type, and cannot drain water quickly. To address this problem, a new type of waterproof structure needs to be designed. Utility Model Content

[0003] The utility model aims to solve the deficiencies of the prior art and provides a novel waterproof structure for construction joints.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a novel waterproof structure at construction joints, comprising a steel plate waterstop, a waterproof coating layer, a first waterproof membrane, a foam concrete layer, and a second waterproof membrane. The steel plate waterstop is buried in the middle position of the concrete structure top plate perpendicular to the construction joint surface, a waterproof coating layer is applied at the construction joint on the top surface of the concrete structure top plate, a first waterproof membrane is laid on the waterproof coating layer, a foam concrete layer is arranged on the first waterproof membrane, and a second waterproof membrane is laid on the foam concrete layer.

[0005] Furthermore, the center line of the steel plate waterstop coincides with the construction joint, ensuring that the width of the steel plate waterstop in the top plate of the concrete structure on both sides of the construction joint is half of the total width.

[0006] Furthermore, the length of the waterproof coating layer on the left and right sides of the construction joint is not less than 20 cm.

[0007] Furthermore, the first waterproof membrane is self-adhesive.

[0008] Furthermore, the foamed concrete layer has a trapezoidal cross-section structure that is high in the middle and low on both sides.

[0009] Furthermore, the thickness of the middle part of the foam concrete layer is 20 cm.

[0010] The beneficial effects of the utility model are as follows: the utility model adopts a four-layer waterproofing form to eliminate the hidden dangers of water leakage, the coating, coiled material and structural slope are used in combination, the waterproof coating can fill and bond the cracks, and at the same time, due to the existence of the foam concrete slope, rainwater can be quickly drained away and will not accumulate at the construction site, ensuring 100% watertightness.

[0013] The drawings in this utility model are all schematic diagrams, and their sizes do not represent actual sizes;

[0014] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0016] like Figure 1 As shown, a new waterproof structure at the construction joint includes a steel plate water stop 1, a waterproof coating layer 3, a first waterproof roll 4, a foam concrete layer 5, and a second waterproof roll 6. The steel plate water stop 1 is buried in the middle position of the concrete structure top plate 2 perpendicular to the construction joint surface. The waterproof coating layer 3 is applied at the construction joint on the top surface of the concrete structure top plate 1. The first waterproof roll 4 is laid on the waterproof coating layer 3. The foam concrete layer 5 is arranged on the first waterproof roll 4. The second waterproof roll 6 is laid on the foam concrete layer 5. The construction joint of the concrete structure top plate 1 is waterproofed by using the middle buried type, the external pasting type, and the reinforcement type.

[0017] The center line of the steel plate water stop 1 coincides with the construction joint, ensuring that the width of the steel plate water stop 1 in the concrete structure top plate 2 on both sides of the construction joint is half of the total width.

[0018] The length of the waterproof coating layer 3 on the left and right sides of the construction joint is not less than 20 cm.

[0019] The first waterproof coiled material 4 is self-adhesive, ensuring good seamless bonding with the waterproof coating layer 3.

[0020] The foamed concrete layer 5 is a trapezoidal cross-section structure with a high middle and low sides, so that rainwater can flow away along the trapezoidal structure.

[0021] The thickness of the middle part of the foamed concrete layer 5 is 20 cm.

[0022] The manufacturing process of the utility model is as follows: firstly, the concrete structure top plate 2 and the steel plate water stop 1 are welded and set, after the concrete pouring is completed, the concrete top surface is ensured to be clean, a waterproof coating layer 3 is applied at the construction joint of the top surface, a first waterproofing membrane 4 is laid, a foamed concrete layer 5 is sloped and compacted on the first waterproofing membrane 4, and finally a second waterproofing membrane 6 is laid on the foamed concrete layer 5 as the future adjacent water surface to directly receive the scouring of rainwater. Using simple and common materials and applying this structural type, the hidden danger of leakage is fundamentally cut off.

[0023] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
