Abstract
The utility model belongs to the technical field of the waterstop, specifically say and relate to a compound plastics waterstop. The main technical scheme is as follows: the water-stop belt comprises a plastic water-stop belt body and anchoring parts arranged at the two transverse sides of the water-stop belt body; the upper surface and the lower surface of the belt body of the anchoring part are provided with fiber layers which form an integral structure with the belt body. The novel composite plastic water stop has the characteristics of simple structure, convenience in construction and firmness in bonding with a construction joint concrete matrix.
Description
Technical Field
The utility model belongs to the technical field of the waterstop, specifically say and relate to a compound plastics waterstop.
Background
The plastic water stop belt has various types, is mainly used for projects such as capital construction projects, underground facilities, tunnels, sewage treatment plants, water conservancy projects, subways and the like, and is used for preparing and allocating concrete for expansion joints of gates, dam bottoms, building projects, underground buildings and the like. The rubber water stop belt is widely applied, has good elasticity, wear resistance, aging resistance and tear resistance, has strong adaptive deformability, can effectively prevent seepage and water leakage of construction joints, and is commonly used for waterproofing and seepage prevention of construction joints of tunnel engineering at present.
In order to facilitate the installation and construction of the water stop, generally, bonding layers are arranged on two sides of the water stop, and an operator directly presses the bonding layers on two sides of a construction joint to quickly position the water stop, but the bonding strength of the self-bonding layer of the structure is not high, the self-bonding layer is not combined with a concrete matrix of the construction joint in a long-acting manner, and most of the self-bonding layer is dropped and leaked after the self-bonding layer is used for a period of time; secondly, when the water stop belt is prepared, a layer of plastic film is required to be covered on the self-adhesive layer in advance, so that the viscose pollution is prevented, the adhesive force is lost, the film needs to be torn off again during construction, the construction steps are increased, the construction period is prolonged, and if the film is not completely removed or the film is not removed due to negligence, the self-adhesive layer is separated from the combination of the concrete, so that the water seepage problem of the construction joint is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, construction convenience just bond firm novel compound type plastics waterstop with construction joint concrete base member.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a compound plastics waterstop, includes the plastics waterstop area body, set up in the anchor portion of the horizontal both sides of waterstop area body, the area body upper surface of anchor portion, lower surface all are provided with the fibrous layer that forms integrative structure with it.
The additional technical characteristics of the composite plastic water stop belt also comprise:
-the fibre layer is non-woven fabric fibres or glass fibre reinforced plastics fibres;
the non-woven fabric is polyester, polypropylene or polyethylene.
The utility model provides a compound plastics waterstop compares with prior art, has following advantage: firstly, fiber layers are arranged on the upper surface and the lower surface of the anchoring part which forms the two transverse sides of the composite plastic water stop belt, one side surface of the fiber layer can be fused with the water stop belt together through high temperature (the temperature of fusion of the surface of the plastic water stop belt body is generally between 90 and 180 ℃) to form a firm connecting layer, and the other side surface of the fiber layer is in a cluster shape, a cluster shape or a plush shape, so that the fiber layer can also be deeply embedded into poured wet concrete to be solidified into a whole, and the advantages of obviously improving the installation strength and the sealing performance of the water stop belt body are achieved; and secondly, because the fiber layers are directly arranged on the two side surfaces of the plastic water stop belt, the water stop belt is installed while the construction joint concrete prefabrication construction is carried out, so that the construction links are saved, the construction period is shortened, and the construction cost is saved.
Drawings
Fig. 1 is a schematic structural view of the composite plastic water stop of the present invention.
Detailed Description
The structure and the working principle of the composite plastic water stop provided by the present invention are further described in detail with reference to the accompanying drawings.
As shown in fig. 1, the structure of the composite plastic water stop of the present invention is schematically illustrated. The structure of the novel composite plastic water stop belt comprises a deformation area 11 in the middle and plastic water stop belt bodies composed of anchoring areas 12 and 13 embedded in the concrete structure 2 at two sides of the deformation area, wherein the upper surface and the lower surface of the anchoring area are provided with fiber layers 14 and 15 which form an integral structure with the anchoring area through high temperature. That is, in the preparation of the composite type plastic waterstop, the upper and lower surfaces of the anchoring zone body are melted by high temperature, then the fiber layers 14 and 15 formed of non-woven fabric made of polyester, polypropylene or polyethylene are pressed against the upper and lower surfaces of the melted anchoring zone body, and after cooling, one side surfaces 141 and 151 forming the fiber layers are integrated with the fiber layers, and the other side surfaces 142 and 152 forming the fiber layers are combined with the cement concrete 2 to be poured and constructed, thereby forming an integrated structure.
The materials of the fiber layer can be selected into a bulk or a cluster felt body, glass fiber and other materials, namely the fiber layer of the material can be fused with the plastic of the water stop body to form an integral structure, and can be fused with the poured concrete to form an integral structure, so that the bonding performance of the water stop and the concrete is greatly improved, and the sealing and water stopping effect of the water stop is improved.
In the process of fusion bonding the fiber layer and the anchoring zone forming the water stop, the melting temperature can be selected according to the plastic material forming the water stop, and the melting temperature is selected correspondingly, such as 70-115 ℃ of polystyrene, 160-170 ℃ of polypropylene, 75-90 ℃ of polyvinyl chloride or 170-180 ℃ of nylon 12.
