Description

Technical Field

[0001] The utility model belongs to the technical direction of building waterproofing, and specifically relates to a waterproof end node structure of a parapet wall. Background Art

[0002] A parapet refers to the low wall around the roof of a building. Its main function is to protect the safety of construction workers and serve as a decoration. It is also the waterproof brick finishing touch for roof waterproofing construction to prevent water seepage in the waterproof layer. Therefore, parapets are widely used in modern buildings because of their unique functions in architectural modeling and waterproof structure.

[0003] The node details of the roof waterproofing project are an important part of the waterproofing project. In addition to the impact of construction on leakage, it is particularly important to do a good job in the detailed structural treatment and related technical design.

[0004] In general roof parapet construction, rectangular grooves are generally used as the end nodes of waterproof membranes. However, the traditional rectangular groove ends are generally facing outward or upward, which cannot prevent rainwater from entering. This patent introduces a waterproof end node with a wedge-shaped groove. The wedge-shaped slope formed makes the waterproof membrane stick more firmly, and can also isolate rainwater from the outside through the groove, thereby playing a better waterproof role. Utility Model Content

[0005] The utility model aims to provide a parapet waterproof end node structure for existing devices to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a parapet waterproof end node structure, including parapet steel bars and wedge-shaped prefabricated polystyrene boards, characterized in that: the position of the wedge-shaped prefabricated polystyrene boards is reserved for the parapet steel bars when they are tied, the outer side of the parapet steel bars is wrapped with a template, the inner side of the template is pasted and fixed with a wedge-shaped prefabricated polystyrene board, and the top of the wedge-shaped prefabricated polystyrene board is cast into a downward groove.

[0007] The utility model further illustrates that a steel pipe is fixed on the outer side of the template, a screw is threadedly connected to the steel pipe, the screw penetrates and connects the template and the steel pipe, and a wooden block is tightly attached to the top of the template.

[0008] The utility model further illustrates that a waterproof coiled material is laid on the wedge-shaped inclined surface.

[0009] The utility model further describes that a metal strip is fixed at the end of the waterproof coiled material.

[0010] The utility model further describes that the exterior of the waterproof coiled material is coated with cement mortar.

[0011] The utility model further describes that the node method of the waterproof end of the parapet is used for the parapet.

[0012] Compared with the prior art, the beneficial effect achieved by the utility model is that the utility model pre-sets a wedge-shaped prefabricated polystyrene board, and forms a downward groove and a wedge-shaped slope after pouring, so that the entire wall is not easy to store water, thereby forming a better waterproof effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution: a parapet waterproof end node structure, including a parapet steel bar 1 and a wedge-shaped prefabricated polystyrene board 5. The parapet steel bar 1 reserves the position of the wedge-shaped prefabricated polystyrene board 5 when tying. The outer side of the tied parapet steel bar 1 is wrapped with a template 6. The inner side of the template 6 is fixed with a wedge-shaped prefabricated polystyrene board 5. The top of the wedge-shaped prefabricated polystyrene board 5 is cast with a downward groove 9. The groove 9 can prevent rainwater from entering, is not easy to store water, and has a better waterproof effect.

[0020] A steel pipe 2 is fixed to the outside of the template 6, and a screw 3 is threadedly connected to the steel pipe 2. The screw 3 penetrates and connects the template 6 and the steel pipe 2. A wooden square 4 is closely attached to the top of the template 6 to reinforce the template 6 and facilitate the later concrete pouring.

[0021] After the parapet concrete is poured, the formwork 6, the wooden square 4 and the wedge-shaped prefabricated polystyrene board 5 are removed after air drying, and the wedge-shaped inclined surface is paved with a waterproof roll 7. The formed wedge-shaped inclined surface makes the waterproof roll 7 more firmly adhered, and the inclined surface is less likely to store water and is easy to air dry;

[0022] A metal pressure strip 8 is fixed at the end of the waterproof coiled material 7, and the end is sealed with a sealing material to avoid the hidden danger of water leakage in the later stage;

[0023] The outside of the waterproof membrane 7 is coated with cement mortar for protection, and after it is air-dried, waterproof material is applied again to prevent corrosive rainwater from corroding the wall;

[0024] The node method of the waterproof end of the parapet is used for parapets, which can be set in places where there are many elderly people and children to protect the safety of residents;

[0025] Working principle:

[0026] The wedge-shaped slope and groove 9 cast by the wedge-shaped prefabricated polystyrene board 5 are not easy to store water, reducing the possibility of water seepage. The wedge-shaped slope is mainly suitable for parapets with higher heights, which can better ensure the safety of residents. The outermost layer of the parapet is coated with waterproof material to avoid corrosion from acidic rainwater, and the service life is longer, and the waterproof effect is better.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
