Description
Technical Field
The utility model belongs to the technical field of the waterstop, specific saying relates to a from telescopic waterstop.
Background
The waterstops are of various types, and the rubber waterstops are most widely applied. The concrete is mainly used for the 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 the concrete for the expansion joints of gates, dam bottoms, building projects, underground buildings and the like.
The general rubber waterstop has consistent cross-section thickness, when the general rubber waterstop is installed in an expansion joint, the anchoring parts on two sides of the waterstop deform before the central belt body under the pulling stress, so that the anchoring parts tear with concrete, the waterstop falls off, the expansion joint permeates and leaks, and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, superior and the waterstop of telescopic performance use firm novel from telescopic waterstop.
In order to achieve the above object, the utility model adopts the following technical scheme:
a self-telescopic water stop belt structurally comprises a rubber water stop belt body, wherein anchoring parts connected with a base body are arranged on two transverse sides of the belt body; the middle part of the water stop belt body is a deformation area which stretches along the transverse direction, the deformation area is in a gradual change arc structure shape, and the thickness of the deformation area is smaller than that of the anchoring part belt body.
The additional technical characteristics of the self-telescopic water stop belt also comprise that:
the upper and lower surfaces of the deformation zone body are symmetrical arc-shaped or wavy
The number of the deformation zones arranged at the center of the water stop strip body is multiple, and a longitudinal rib with the thickness not smaller than the thickness of the anchoring part strip body is arranged between every two adjacent deformation zones;
the section of the longitudinal rib is rhombic or rectangular, and the longitudinal rib is connected with the deformation zone belts on the two sides through transition arcs;
-side battens are arranged in the longitudinal ribs.
Compared with the prior art, the utility model provides a from telescopic waterstop has following advantage: firstly, because the center of the self-telescopic water stop is provided with the deformation zone which stretches along the transverse direction, the belt body of the deformation zone is in a gradual-change arc-shaped structure shape, and the thickness of the deformation zone is smaller than that of the belt body of the anchoring part, the deformation zone stretches and deforms before the anchoring part in the using process, the abrasion of the belt body of the anchoring part on concrete is slowed down, and the self-telescopic water stop has the advantages of firm installation and use and excellent stretching performance; meanwhile, the upper surface and the lower surface of the band body in the deformation area are in a symmetrical arc shape or a wave shape, so that the structural strength of the water stop band is improved on the premise of increasing deformation after the water stop band is pulled and stressed, and the problem of band body tearing caused by overlarge deformation amplitude is avoided; secondly, should set up the deformation zone that area body thickness is less relatively on current rubber belt body from telescopic waterstop to obvious improvement the elasticity performance of waterstop, have simple structure, be convenient for manufacturing, the installation is convenient, long service life's advantage.

Detailed Description
The structure and the working principle of the self-telescopic water stop provided by the present invention will be further described in detail with reference to the accompanying drawings.
Referring to fig. 1 to fig. 3, the structure of the self-telescopic water stop is schematically illustrated. The structure of constituting this from telescopic waterstop includes the rubber waterstop area body 1, and the horizontal both sides of the area body 1 set up the anchor portion 2 of being connected with the base member, and the center of the waterstop area body 1 sets up along the deformation zone 3 of horizontal flexible, and the thickness of the 3 area bodies in deformation zone is less than the thickness of the 2 area bodies in anchor portion and the upper and lower surface of the 3 area bodies in deformation zone is circular-arc or wavy for the symmetry.
The working principle is as follows: the rubber waterstop body 1 is arranged in the expansion joint, the anchoring parts 2 on the two transverse sides of the rubber waterstop body are installed with the concrete structure of the expansion joint base body, the deformation area 3 in the center of the waterstop body can stretch out and draw back along the transverse direction, and because the thickness of the body of the deformation area 3 is smaller than that of the body of the anchoring parts 2, when the waterstop is pulled by stress, the deformation area 3 stretches out and draws back in advance of the deformation of the anchoring parts 2, so that the firm installation and tight sealing of the anchoring parts 2 and the concrete base body are ensured.
In the structure constituting the self-extensible water stop,
in order to improve the expansion range of the deformation zones 3, the number of the deformation zones 2 arranged at the center of the water stop belt body 1 is multiple, and the longitudinal ribs 4 with the thickness not less than that of the belt body of the anchoring part 2 are arranged between the adjacent deformation zones 3, so that the structural strength of the water stop belt is improved on the premise of increasing the deformation, and the problem of belt body tearing caused by overlarge deformation range is avoided;
preferably, the section of the longitudinal rib 4 is rhombic or rectangular, so that the tensile strength can be effectively enhanced, the longitudinal rib 4 is connected with the deformation zones 3 on the two sides through the transition arc 5, the injection molding and vulcanization are simple, and the production and the manufacture are convenient;
the side-standing laths 6 are arranged in the longitudinal ribs 4, so that the telescopic structure and the center of the water stop belt tend to be more spring in the telescopic process, the supporting tension of the water stop belt can be obviously improved, and the service life of the water stop structure is prolonged.
