Description

Technical Field

[0001] The utility model relates to the technical field of deformation joint waterproofing, in particular to a waterproof structure for deformation joints of factory buildings. Background Art

[0002] Industrial plants can be divided into single-story industrial buildings and multi-story industrial buildings according to their building structure. Plants are an essential component of industrial production. Deformation joints are the general term for expansion joints, settlement joints and seismic joints. Buildings often deform under the influence of external factors, leading to cracks or even damage. Deformation joints are structural joints reserved for this situation, and plant buildings will also reserve deformation joints during construction.

[0003] After searching, the patent with application number CN202321340977.9 discloses a deformation joint waterproof structure, including two relatively arranged structural walls, a deformation joint is formed between the two structural walls, a waterproof structure is installed on the top of the deformation joint, an insulation board is installed in the middle of the deformation joint, and a drainage groove is installed at the bottom of the deformation joint. The waterproof structure includes a waterproof membrane laid on the top of the two structural walls and covering the deformation joint, and a layer of aluminum plate is provided on the waterproof membrane. The comparative document sets a three-layer waterproof structure on the deformation joint, but the deformation joint will experience thermal expansion and contraction under different temperatures, which will cause the waterproof structure on the deformation joint to be pulled, and it is easy to break after reaching the fatigue limit of the aluminum plate. If the waterproof structure breaks, it is necessary to reinstall the waterproof structure on the deformation joint, which is more troublesome to handle.

[0004] The existing deformation joint waterproof structure has the above-mentioned problem that the deformation joint waterproof structure is not resistant to temperature changes. In view of this, we propose a waterproof structure for the deformation joint of a factory building. Utility Model Content

[0005] In order to solve the above problems existing in the prior art, the utility model provides a waterproof structure for deformation joints of factory buildings.

[0006] The technical solution of the utility model is as follows:

[0007] A waterproof structure for expansion joints of a factory building, comprising a group of fixing plates, a reinforcement plate and a cover plate, wherein a group of fixing plates are respectively pre-buried at both sides of the structural joint of the factory building, and two reinforcement plates connected by bolts are installed between the two fixing plates; the upper parts of the two reinforcement plates are connected to the cover plate and two opening parts are provided on the bottom surface of the cover plate; an extension part is provided between the two reinforcement plates, and one of the extension parts is provided with a folding edge that can cover the other extension part; the folding edge is in contact with the lower surface of the cover plate; and a barrier part extending upward is installed on the top of the reinforcement plate.

[0008] Preferably, a water stop strip A is provided between the two reinforcement plates.

[0009] Preferably, waterproof glue is used to seal the fixed plate and the structural joint of the factory building.

[0010] Preferably, arc-shaped portions are provided on the two extension portions, the opening directions of the two arc-shaped portions are the same, and the water stop strip A is located between the two arc-shaped portions, and strip-shaped protrusions are provided on the opposite sides of the arc-shaped portions.

[0011] Preferably, the tops of the two fixing plates are respectively provided with arc-shaped curling edges opening outwards, and both ends of the cover plate are respectively provided with clamping protrusions adapted to the arc-shaped curling edges, and the clamping protrusions are arranged toward the inner side of the cover plate.

[0012] Preferably, the top of the fixed plate is provided with a hook edge A opening outward, the bottom of the reinforcing plate is provided with a hook edge B buckled with the hook edge A, and a water stop strip B is provided between the hook edges A and B.

[0013] Preferably, an arched portion is provided on the fixing plate, and a positioning portion matched with the arched portion is provided on the reinforcing plate.

[0014] Preferably, a support plate with an opening facing upward is connected between the bottoms of the two reinforcement plates, a waterproof layer is provided on the outer side of the support plate, and a fire barrier strip is installed on the inner side of the support plate.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model sets a fixing plate embedded in the structural joint, and the reinforcement plate and the cover plate are connected to the structural joint through the fixing plate, so as to avoid the problem of loose connection and looseness caused by direct installation on the wall. When the structural joint expands and contracts under different temperatures, the reinforcement plate and the cover plate will be pulled to slightly deform due to the ductility of their own materials, so as to avoid failure of the waterproof structure caused by thermal expansion and contraction;

[0017] 2. The utility model has a cover plate that cooperates with the fixed plate and the reinforcement plate respectively, and the lower surface of the cover plate abuts against the folded edge. In this way, when the construction joint is expanded outward by force, the two ends of the cover plate connected by the convex and the arc-shaped curling edge will be pulled outward by force. Since the cover plate abuts against the folded edge, the cover plate has no space to move downward. When the two ends of the cover plate are pulled outward, the distance between the two expanded parts will increase, and the increased expanded part will abut against the barrier part, further improving the strength of this waterproof structure.

[0026] See also Figures 1 to 5 A waterproof structure for expansion joints of a factory building comprises a set of fixing plates 1, a reinforcing plate 2 and a cover plate 3.

[0027] A fixing plate 1 is provided, and the fixing plate 1 is installed on the structural joint reserved in the factory building through embedded expansion bolts. There is a gap between the two fixing plates 1. The reinforcement plate 2 is installed above the fixing plate 1. The two reinforcement plates 2 are arranged opposite to each other and fixed by bolts. The cover plate 3 is buckled on the fixing plate 1 with its opening downward. The water stop strip A4 is a water stop strip that expands when exposed to water and is commonly used in construction.

[0028] Furthermore, an extension portion 5 is provided between the two reinforcement plates 2, and one of the extension portions 5 is provided with a folded edge 6 that can cover the other extension portion 5; the folded edge 6 abuts against the lower surface of the cover plate 3; and an upwardly extending blocking portion 14 is installed on the top of the reinforcement plate 2.

[0029] The extension part 5 is located on the opposite side of the two reinforcement plates 2, and the extension part 5 extends upward. The folded edge 6 is formed by the deformation of the end of one of the extension parts 5, and can be placed on the other extension part 5 to block the gap between the two extension parts 5 and reduce the entry of moisture. The fixed plate 1 is sealed and fixed to the structural seam of the factory building with a waterproof sealant to prevent moisture from entering between the fixed plate 1 and the structural seam.

[0030] Furthermore, arc-shaped portions 7 are provided on the two extension portions 5 , the opening directions of the two arc-shaped portions 7 are the same, and the water stop strip A4 is located between the two arc-shaped portions 7 , and a strip-shaped protrusion 8 is provided on the opposite side of the arc-shaped portions 7 .

[0031] By setting the arc portion 7, the arc portion 7 is located in the middle of the extension portion 5, the two arc portions 7 are deformed in the same direction, and the water stop strip A4 is set between the two arc portions 7. When the two extension portions 5 are fixed together by bolts, the water stop strip A4 between the two arc portions 7 will be deformed, so that the seal between the water stop strip A4 and the two extension portions 5 is tighter to prevent the entry of moisture.

[0032] Furthermore, the tops of the two fixing plates 1 are respectively provided with arc-shaped curling edges 9 opening outwards, and both ends of the cover plate 3 are respectively provided with clamping protrusions 10 adapted to the arc-shaped curling edges 9 , and the clamping protrusions 10 are arranged toward the inner side of the cover plate 3 .

[0033] By setting the arc-shaped curling edge 9, the arc-shaped curling edge 9 is located at the top of the fixing plate 1, and the clamping protrusions 10 are installed at the two ends of the bottom of the cover plate 3, the clamping protrusions 10 are set toward the inner side of the cover plate 3, and the arc-shaped curling edge 9 opens outward. The clamping protrusions 10 can be clamped into the arc-shaped curling edge 9, which can facilitate the installation between the cover plate 3 and the fixing plate 1.

[0034] Furthermore, a hook edge A11 opening outward is provided on the top of the fixing plate 1, a hook edge B12 buckled with the hook edge A11 is provided on the bottom of the reinforcing plate 2, and a water stop strip B13 is provided between the hook edge A11 and the hook edge B12.

[0035] By setting the hook edge A11 and the hook edge B12, the hook edge A11 is installed on the top of the fixed plate 1, and the hook edge B12 is installed on the bottom of the reinforcement plate 2. During installation, the hook edge A11 and the hook edge B12 will contact each other and slightly deform. The water stop strip B13 can be a water stop strip that expands when in contact with water commonly used in construction. The water stop strip B13 can be placed on one side of the hook edge A11 or the hook edge B12. When the hook edge A11 and the hook edge B12 contact each other, the water stop strip B13 can be slightly deformed, which is convenient for use.

[0036] At the same time, the two reinforcing plates 2 are connected to the cover plate 3 above and two support parts 15 are provided on the bottom surface of the cover plate 3. By setting the blocking part 14, the blocking part 14 is located on the top of the reinforcing plate 2, and the support part 15 is located on the bottom wall of the cover plate 3. The lower surface of the cover plate 3 abuts against the folding edge 6. In this way, when the construction joint is subjected to force and expands outward, the two ends of the cover plate 3 connected by the clamping protrusion 10 and the arc-shaped curling edge 9 will be pulled outward by force. Since the cover plate 3 abuts against the folding edge 6, the cover plate 3 has no space to move downward. When the two ends of the cover plate 3 are pulled outward, the distance between the two support parts 15 will increase, and the enlarged support part 15 will abut against the blocking part 14, thereby further improving the strength of this waterproof structure.

[0037] Furthermore, an arched portion 16 is provided on the fixing plate 1, and a positioning portion 17 adapted to the arched portion 16 is provided on the reinforcing plate 2; by providing the arched portion 16, the arched portion 16 is located at the top of the fixing plate 1, and the positioning portion 17 is located on the reinforcing plate 2, the arched portion 16 can form a higher water blocking belt on the fixing plate 1, which can further reduce the water entering therein.

[0038] Furthermore, a support plate 18 with an opening upward is connected between the bottoms of the two reinforcement plates 2, a waterproof layer 19 is provided on the outer side of the support plate 18, and a fire-blocking strip 20 is installed on the inner side of the support plate 18; by setting the support plate 18, the support plate 18 is installed at the bottom of the reinforcement plate 2, the support plate 18 is made of an alloy with excellent elasticity, the waterproof layer 19 is installed on the outer side of the support plate 18, so as to further reduce the entry of moisture, and the fire-blocking strip 20 is installed on the inner side of the support plate 18, which can prevent open flames from entering the other side of the structural seam.

[0039] The working principle of this utility model:

[0040] In the utility model, two fixing plates 1 are pre-buried on the structural seam of the factory building, and then the gap between the fixing plate 1 and the structural seam is sealed with waterproof glue. During installation, the two reinforcement plates 2 are first connected together, and the water stop strip A4 is placed between the two arc-shaped portions 7. Then, the two reinforcement plates 2 are fixed by bolts. At this time, the positioning portion 17 is placed above the arch portion 16, and the hook edge A11 and the hook edge B12 will contact each other and deform to a certain extent, so that the spacing gap between the fixing plate 1 and the reinforcement plate 2 is smaller. After the two reinforcement plates 2 are completely fixed, the protrusion 10 of the cover plate 3 is completely inserted into the arc-shaped curling edge 9. Waterproof materials are arranged in the water flow path to prevent water from entering the structural seams of the factory building.
