Description

Technical Field

[0001] The present application relates to the technical field of partial roof repair, and in particular to a partial roof repair structure. Background Art

[0002] When a house is in use, the roof protective layer may be damaged and leakage may occur. However, in reality, due to the influence of many factors, there is a possibility that the user will only carry out partial repairs, such as the customer's financial situation, the roof of the building has multiple users at the same time (only one of the customers has a repair demand), etc.; the existing partial roof repairs are either to apply a waterproof layer on the entire roof, which is difficult to solve the problem of internal water seepage in the roof, has a high probability of rework, and is not aesthetically pleasing and cannot meet customer needs; the other is to demolish the area that needs repair, and demolish a certain width of the adjacent unrepaired area and the overlap of the repair area to expose the original waterproof layer of 1 meter wide in the adjacent part, which is used to overlap with the newly constructed waterproof layer of the demolished part. Although the roof can be partially repaired, due to the flow characteristics of water, the moisture in the insulation layer of the adjacent area will still flow along the interlayer gap to the insulation layer of the repair area, and seep into the room along the floor slab. Utility Model Content

[0010] Further preferably, the isolation portion extends upward from the floor surface out of the insulation layer to the protective layer.

[0011] Further preferably, the isolation portion extends out of the insulation layer by 10 mm to 30 mm, which can separate the insulation layer of the maintenance area from that of the adjacent area, avoids protrusions from the protective layer to affect the appearance, and makes the protective layer integrated.

[0012] Preferably, the waterproof layer is a non-curing waterproof coating and SBS asphalt membrane, a polyurethane waterproof membrane and SBS asphalt membrane, or an epoxy resin waterproof coating and SBS asphalt waterproof membrane laid in sequence.

[0013] The beneficial effects of this application are:

[0014] (1) An isolation part is provided to separate the maintenance area from the adjacent area, and a water retaining structure is provided at the inner corner between the isolation part and the floor slab to prevent moisture in the adjacent area from penetrating into the maintenance area through the joint between the isolation part and the floor slab, thereby improving the anti-leakage effect of the maintenance area.

[0024] The following will be combined with the drawings of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described in the present application are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0025] Combination Figure 1 and Figure 2 The local roof repair structure is used for repairing the local roof, including a floor 10 and a roof structure 20, wherein the roof structure 20 is laid on the floor 10, wherein the roof structure includes an insulation layer 201 and a protective layer 202, wherein the insulation layer 201 and the protective layer 202 are laid on the floor 10 in sequence, and the roof structure 20 is divided into a maintenance area 100 and an adjacent area 200.

[0026] An isolation portion 30 is vertically provided on the floor 10, and the isolation portion 30 is provided between the maintenance area 100 and the adjacent area 200, and is used to separate the maintenance area 100 from the adjacent area 200. A water retaining structure 40 is provided at the inner corner between the floor 10 and the isolation portion 30 in the maintenance area 100, and is used to prevent the moisture in the adjacent area 200 from flowing to the maintenance area 100. A waterproof layer 50 is provided between the roof structure 20 of the maintenance area 100 and the floor 10 and the isolation portion 30, so as to further improve the waterproof performance of the maintenance area 100. This arrangement can effectively block the moisture in the insulation layer 201 in the adjacent area 200 from flowing to the maintenance area 100, thereby realizing partial repair of the roof, and can effectively prevent the moisture from flowing to the maintenance area 100 and causing the floor 10 to leak, thereby reducing the probability of rework and repair in the later stage.

[0027] Among them, the waterproof layer 50 can be a non-curing waterproof coating and SBS asphalt membrane, a polyurethane waterproof membrane and an SBS asphalt membrane, or an epoxy resin waterproof coating and an SBS asphalt waterproof membrane, etc., which are laid in sequence. In this embodiment, the waterproof layer 50 is a non-curing waterproof coating and an SBS asphalt membrane. The non-curing waterproof membrane has good self-healing properties and high adhesion. The SBS asphalt membrane has high elasticity and fatigue resistance, can withstand deformation and vibration of the structure, is not easy to crack and damage, and has strong puncture resistance and tear resistance, and can resist external physical damage. The combination of the two can improve the waterproof performance. In some embodiments, a slope layer is provided between the floor slab in the maintenance area and the waterproof layer.

[0028] Combination Figure 2 The water retaining structure 40 includes a notch 401 opened on the floor 10, and a waterproof material 402 filling the notch 401, wherein the waterproof material 402 forms a rounded corner structure at the inner corner between the floor 10 and the isolation portion 30, wherein the notch 401 is in a "V" shape, and the notch 401 is opened perpendicular to the floor 10 along the isolation portion 30, and can be opened by a tool such as an electric pick; the waterproof material filled in the notch and the waterproof material forming the rounded corner are integrated, and this arrangement can not only increase the water retaining surface and enhance the waterproof effect, but also facilitate the opening and cleaning of the notch 401, thereby reducing the repair time; in this embodiment, the notch 401 is 30×30mm to prevent the notch 401 from being opened too large. Greatly affects the structure of the floor 10; the radius of the fillet is 30-60mm, preferably 40mm; the fillet can prevent the stress concentration of the waterproof layer 50 at the inner corner from causing cracking and damage, and the waterproof material 402 can be a rigid plugging king, which has strong adhesion and water resistance, and is not easy to fall off and fail after being immersed in water for a long time. A solid waterproof layer 50 can be formed at the inner corner between the isolation part 30 and the floor 10, between the floor 10 and the isolation part 30, and the notch 401 can increase the water retaining surface, and it is also convenient to fill the waterproof material 402 into the notch 401, effectively preventing the risk of moisture in the adjacent area 200 penetrating into the maintenance area 100 through the joint between the isolation part 30 and the floor 10.

[0029] Combination Figure 1 The isolation portion 30 extends from the insulation layer 201 to the protective layer 202, and can separate the maintenance area from the insulation layer in the adjacent area. Specifically, the isolation portion extends from the insulation layer by 10 mm to 30 mm, preferably 20 mm, to control the laying thickness of the protective layer to avoid high cost due to excessive thickness and poor protection due to excessive thinness;

[0030] Among them, the waterproof layer 50 can be extended upward along the surface of the floor 10 and the isolation part 30 in the maintenance area 100 to the roof structure 20. In this embodiment, the waterproof layer 50 extends into the protective layer 202, and the protective layer 202 can hide the waterproof layer 50 to improve the aesthetics after repair; of course, the waterproof layer 50 can also extend to be flush with the upper surface of the protective layer 202.
