Description

Technical Field

[0001] The invention belongs to the technical field of construction, and in particular relates to a leak-proof structure of a building. Background Art

[0002] A floor slab refers to a component whose dimensions in two plane directions are much larger than its dimensions in the thickness direction and which bears vertical loads. Depending on the materials used, floor slabs can be divided into wooden slabs, brick arch slabs, reinforced concrete slabs and steel lining load-bearing slabs.

[0003] The leakage prevention of floor slabs can be summarized into two categories, one is material waterproofing, the other is structural waterproofing. The former relies on the properties of the material itself, while the latter achieves the purpose of waterproofing through appropriate design and processing, and does not simply rely on the properties of the material. There are generally two points worth noting in floor leakage prevention. One is that the floor slab laying itself has defects and is prone to leakage, and the other is that the joints where water pipes are opened are prone to leakage. Summary of the invention

[0004] In view of the above problems, the present invention provides a leak-proof structure for a building to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a leak-proof structure of a building, comprising a keel structure, the sides of the keel structure are fixedly connected to a wall, the interior of the keel structure is filled with a foamed cement board, the keel structure comprises a plurality of upper keels, a plurality of lower keels and a plurality of frames, the bottom ends of the plurality of upper keels are each provided with a plurality of first connection ports facing inward, the top ends of the plurality of lower keels are each provided with a plurality of second connection ports facing inward, the plurality of first connection ports are respectively engaged with adjacent second connection ports, the inner sides of the plurality of frames are each provided with connection blocks protruding outward, the plurality of connection blocks are respectively engaged with the two ends of the corresponding upper keels or the two ends of the lower keels, a first waterproof cloth layer is laid on the top of the keel structure, and a first mortar layer is fixedly connected to the top of the first waterproof cloth layer.

[0006] Preferably, the plurality of upper keels are all groove-shaped with openings upward, the plurality of lower keels are all groove-shaped with openings downward, and the plurality of frame frames are all groove-shaped with openings outward.

[0007] Preferably, a plurality of mounting strips protrude outward from the inner side of the wall, and the plurality of mounting strips are respectively engaged with one side of a corresponding frame.

[0008] Preferably, both sides of the bottom ends of the multiple upper keels are fixedly connected with first side wings, and the multiple first side wings are respectively distributed alternately with the multiple first connecting ports, and both sides of the bottom ends of the multiple lower keels are fixedly connected with second side wings, and the multiple second side wings are respectively distributed alternately with the multiple second connecting ports, and the multiple first side wings correspond to the multiple second side wings in position.

[0009] Preferably, the top of the first mortar layer is fixedly connected to a floor slab, the top of the floor slab is fixedly connected to a composite surface layer, the bottom end of the keel structure is fixedly attached to a second waterproof cloth layer, the bottom end of the second waterproof cloth layer is fixedly connected to a second mortar layer, and the bottom end of the second mortar layer is fixedly connected to a ceiling.

[0010] Preferably, the first mortar layer and the second mortar layer are both arranged twice, and the edge of the corresponding first waterproof cloth layer or second waterproof cloth layer is reserved in the first arrangement.

[0011] Preferably, a water pipe is inserted and connected to one side of the top of the composite surface layer through an opened connecting port, and a connecting pipe is installed at the bottom end of the water pipe penetrating downward through the ceiling.

[0012] Preferably, a filling port is opened on one side of the top of the composite surface layer, the filling port is in contact with the outer wall of the water pipe, and the interior of the filling port is filled with a filler.

[0013] Technical effects and advantages of the present invention:

[0014] 1. The keel structure of the present invention is reasonably designed, and each part is of equal height. In fact, the entire floor structure is divided into closed blocks, and the structure is stable. In the case of water leakage, it prevents moisture from penetrating into the surrounding area to cause serious consequences. Although the filled foam cement board will reduce the sound insulation effect in the case of water seepage, it can absorb part of the moisture itself, and the first waterproof cloth layer and the second waterproof cloth layer are provided. Unlike waterproof mortar or other materials, the waterproof cloth is a soft material and will not crack due to moisture, so no large-area cracks will be generated, and it can prevent moisture from penetrating. Even if the upper layer leaks, the moisture will not damage the roof, which is convenient for subsequent repairs;

[0015] 2. The present invention opens a filling port at the connection between the composite surface layer of the floor slab and the water pipe. When installing the water pipe, a syringe or other tool can be used to continuously spray adhesive or filler onto the outer wall of the water pipe from the filling port. At the same time, before the adhesive or filler dries, the water pipe is repeatedly pulled in and out and rotated to ensure that the adhesive or filler is sprayed evenly and penetrates into the gap of the connecting port to completely seal the damaged parts of each part, so that the filler is no longer limited to filling the surface gaps, resulting in a poor leak-proof effect. Because an additional connecting pipe is installed at the bottom of the water pipe, it is also convenient to connect other pipes, so that the water pipe does not need to be repeatedly tightened to damage the gap, and the risk of leakage is also reduced.

Multiple connecting blocks 9 are respectively engaged with the two ends of the corresponding upper keel 4 or the two ends of the lower keel 5, so that the various parts of the keel structure 1 are of the same height. In fact, the entire floor structure is divided into closed blocks to maintain structural stability. The various connecting parts of the keel structure 1 are tightened with bolts, avoiding the risk of rust caused by welding of traditional skeletons after a long time. A first waterproof cloth layer 10 is laid on the top of the keel structure 1, and a first mortar layer 11 is fixedly connected to the top of the first waterproof cloth layer 10.

[0025] As a specific embodiment of the present invention, multiple upper keels 4 are all groove-shaped with openings upward, multiple lower keels 5 are all groove-shaped with openings downward, and multiple frames 6 are all groove-shaped with openings outward, thereby reducing the weight of the keel structure 1. The openings are in opposite directions so that the upper keels 4 and the lower keels 5 are face to face instead of face to line, which improves the structural stability and reserves room for thermal expansion and contraction of the skeleton.

After the first laying is dry, the excess edge of the waterproof cloth is cut off, and then the laying is continued to cover the edge of the waterproof cloth, which is the second laying.

[0030] As a specific embodiment of the present invention, a water pipe 20 is connected to one side of the top of the composite surface layer 16 through an opened connecting port, and a connecting pipe 21 is installed at the bottom end of the water pipe 20 penetrating downward through the ceiling 19. The connecting pipe 21 is reserved to connect subsequent pipelines to avoid directly tightening the water pipe 20 after the subsequent filler dries, which will cause pressure on the water pipe 20 and damage the gap.
