Description

Technical Field

[0001] The utility model relates to the technical field of roof quality detection, and more particularly to a detection device for local water-tightness test of a roof waterproof layer. Background Art

[0002] During the waterproofing construction of large-area roofs such as public buildings and factories, the main structure, each waterproof layer, and waterproof protective layer all need to undergo a water-tightness test to ensure that the roof will not leak in the end. When closing the water, it is often limited by the incomplete establishment of the drainage system, and the amount of water required for complete water closure is extremely large, resulting in drainage difficulties and a large amount of water resources wasted. In addition, as the water evaporates during the water closure process, it is necessary to replenish the water multiple times to meet the requirement that the water level at the lowest point is not less than 20mm. For rain gutters installed after the internal drainage form, and for repairing leaks found during large-area water closure, the base of the equipment foundation can be partially closed. The use of traditional brick-built water retaining platforms for partial water closure requires the consumption of more mortar and other consumables, and the masonry and plastering also waste a lot of labor costs.

[0003] Therefore, how to provide a recyclable local water-blocking device for key parts of the roof is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0004] In view of this, the utility model provides a detection device for local water-tightness test of roof waterproof layer, which solves the problems of rain gutters installed after internal drainage in key parts of the roof, repairing leakage points found during large-area water-tightness, and local water-tightness devices at the root of equipment foundation that cannot be turned around, thereby meeting the use requirements of local water-tightness test of roof.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A detection device for local water-tightness test of a roof waterproof layer, comprising a water-tightness ring, a connecting piece, a supporting piece and a weight piece;

[0007] The bottom annular surface of the water-closed ring abuts against the roof, and water is filled in the annular cavity; the bottom surface of the connecting piece is fixed on the top annular surface of the water-closed ring; there are multiple support members, and the multiple support members are arranged parallel to each other and their bottom surfaces are all fixed on the top annular surface of the water-closed ring; the bottom surface of the weight member can abut against the top surfaces of the multiple support members to provide pressure so that the bottom annular surface of the water-closed ring fits tightly against the roof.

[0008] The beneficial effect of the above technical solution is that when conducting a local water-tightness test on a roof, the water-tightening ring is placed on the roof to be tested, the connecting piece is fixed on the top surface of the water-tightening ring, the supporting piece is fixed on the top surface of the connecting piece, and the weight is placed on the supporting piece. The bottom annular surface of the water-tightening ring is tightly fitted to the roof through the weight, and after water is injected into the annular cavity of the water-tightening ring, the leakage situation on the top of the roof is observed to complete the local water-tightness test on the roof.

[0009] Preferably, the water-sealing ring is a rubber tire with an inner diameter of no less than 600 mm and a tire width of no less than 200 mm. The rubber tire has a certain degree of flexibility, and the weight can provide pressure to the rubber tire so that its bottom annular surface conforms to the roof, ensuring that the contact surface between the bottom annular surface of the water-sealing ring and the roof does not leak.

[0010] Preferably, the tire further comprises a gasket, wherein the gasket is a semicircular steel sheet with a wall thickness of 1 mm, and the number of the semicircular steel sheets is multiple, and the multiple semicircular steel sheets are arranged in an array and clamped to the top sidewall of the rubber tire; the connecting piece is a round steel bar with a diameter of 6 mm, and the round steel bar is welded to the top surface of the multiple gaskets. By snapping the semicircular gasket onto the top sidewall of the rubber tire, and welding the round steel bar and the gasket together, a tight connection between the round steel bar and the rubber tire can be achieved.

[0011] Preferably, the support member is an angle steel, the number of the angle steels is two, the openings of the two angle steels are arranged opposite to each other, and the two ends of the bottom surface of the ballast member are respectively in contact with the horizontal plates of the two angle steels. Using the angle steel as the support member, the two openings of the angle steel are arranged opposite to each other to be able to clamp the ballast member.

[0012] Preferably, the distance between the two angle steels is 260 mm.

[0013] Preferably, the rubber tire is inflated to 85%, ensuring the most appropriate effect between the contact area and pressure between the rubber tire and the ground.

[0014] Preferably, the number of the ballast members is multiple, and the multiple ballast members are lime sand bricks. Using lime sand bricks as the counterweight of the rubber tire ensures that the rubber tire fits tightly with the roof while preventing the rubber tire from bursting.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See attached Figures 1 to 3 The embodiment of the utility model discloses a detection device for local water-tightness test of a roof waterproof layer, comprising a water-tightness ring 1, a connecting member 3, a supporting member 4 and a weight member 5;

[0024] The bottom annular surface of the closed water ring 1 abuts against the roof, and water is filled in the annular cavity; the bottom surface of the connecting member 3 is fixed on the top annular surface of the closed water ring 1; there are multiple support members 4, and the multiple support members 4 are arranged parallel to each other and their bottom surfaces are all fixed on the top annular surface of the closed water ring 1; the bottom surface of the ballast member 5 can abut against the top surfaces of the multiple support members 4 to provide pressure so that the bottom annular surface of the closed water ring 1 fits tightly against the roof.

[0025] When conducting a local water-tightness test on the roof, the rubber tire is placed on the test section of the roof, and the connectors, supports and weights are assembled in sequence to ensure that the weights can provide a certain pressure so that the water-tightness ring fits tightly against the roof without leaking. Water is then injected into the annular cavity of the water-tightness ring to observe the leakage of the roof top plate and conduct a local water-tightness test on the roof.

[0026] In this embodiment, the closed water ring 1 is a rubber tire with an inner diameter of 600 mm and a tire width of 200 mm. The flexibility of the rubber tire is used to cooperate with the weight to make it fit tightly with the roof.

[0027] After testing, it was found that when the inflation volume of the rubber tire is 85%, it can ensure the most appropriate effect between the contact area and pressure between the tire and the ground.

[0028] In order to further optimize the above technical solution, it also includes a gasket 2, which is a semicircular steel sheet with a wall thickness of 1 mm. There are multiple semicircular steel sheets, and the multiple semicircular steel sheets are clamped in an array on the top sidewall of the rubber tire; the connecting piece 3 is a round steel with a diameter of 6 mm, and the round steel is welded to the top surface of multiple gaskets 2.

[0029] Since the round steel cannot be directly fixed to the rubber tire, the round steel is fixed by multiple semicircular gaskets. The inner diameter of the semicircular gasket is adapted to the tire width of the rubber tire so that it can be clipped onto the rubber tire. The clipping method can realize the disassembly between the rubber tire and other components. When the rubber tire is severely worn, the local water-tightness test of the roof can be continued by replacing the rubber tire.

[0030] To further optimize the above technical solution, support member 4 is constructed of two angle steels, with their openings facing each other. The bottom ends of ballast member 5 abut against the horizontal plates of the two angle steels. The openings of the two angle steels can clamp the ballast member, ensuring that it can provide a certain amount of pressure for the rubber tire and effectively conduct the local water-tightness test on the roof.

[0031] In this embodiment, semicircular steel sheets, round steel and two angle steels can be welded into an integral steel frame. During the water-tightness test at rain gutters, leakage repair points and other locations, tires are placed with rain gutters, leakage repair points and other locations as the center. The rubber tires can fit perfectly with the concrete surface and the waterproof membrane surface to prevent water from flowing out. The welded steel frame is placed on the top sidewall of the rubber tire, and a weight is placed to make the rubber tire fit tightly with the roof. Finally, water is injected into the annular cavity of the rubber tire to observe the leakage on the top of the roof and perform a water-tightness test.

[0032] When sealing off the water at the root of the equipment foundation, the length of the two angle steels is lengthened by welding, the equipment foundation passes through the center of the annular cavity of the rubber tire, and the weights are symmetrically pressed on both sides of the extended angle steels.

[0033] After multiple on-site tests and a 24-hour closed water test, the initial water level should be no less than 80mm to meet the requirement that the water level at the lowest point of the entire process should be no less than 20mm. Therefore, the height of the water injection in the annular cavity of the rubber tire should be no less than 80mm.

[0034] To further optimize the above technical solution, multiple ballasts 5 are used, each made of sand-lime bricks. The spacing between the two angle steels is 260 mm. The two angle steels can be clamped at opposite ends of the sand-lime bricks. Using the sand-lime bricks as ballasts not only provides pressure for the rubber tire to adhere tightly to the roof, but also prevents the tire from bursting due to the excessive weight of the ballast.

[0035] The detection device provided by the utility model is easy to obtain materials, and the production cost of each set of the device is about 80 yuan, which greatly reduces the cost of the local water-tightness test of the roof.

[0036] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.

[0037] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
