Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a rigid skeleton type back-sticking water stop strip structure. Background Art

[0002] The existing back-sticking waterstop has no self-sustaining property, and is fixed by gluing or steel pads during installation, and the outer surface of the waterstop is easily damaged. The external rubber waterstop produces elastic deformation under various loads, thereby playing a strong seal, effectively preventing water leakage and seepage in the building structure, and playing a shock-absorbing and buffering role. In many engineering construction designs, there are certain expansion and contraction requirements between civil engineering and water and soil structures, and there are problems such as waterproofing and shockproofing. Therefore, the use and installation of rubber waterstops is an effective means to solve the above problems. However, the existing waterstops have the following disadvantages: First, they have no self-sustaining property, and the flatness and straightness of the installation are not easy to control; second, they are fixed by gluing or steel pads, and the process is complicated and they are easy to fall off and deform during construction; third, the back-sticking waterstop is made of rubber, and the outer side is exposed and easily damaged. Utility Model Content

[0017] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0018] like Figure 1 As shown, the rigid skeleton back-stick waterstop includes a back-stick rubber waterstop 1, an anchoring rubber nail 201 connected to the back of the back-stick rubber waterstop 1, a rigid back plate 2 arranged on the back of the back-stick rubber waterstop 1 and between the anchoring rubber nails 201, and limit grooves for docking the template on the rigid back plate 2 at both ends. The back-stick rubber waterstop 1 of this embodiment is different from the traditional back-stick waterstop. The back of the back-stick rubber waterstop is provided with an anchoring rubber nail 201 during production, and the length and size of the anchoring rubber nail 201 are adapted to the rigid back plate 2. The back-stick rubber waterstop 1 is mainly fixed by the anchoring rubber nail 201 and the rigid back plate 2, and can also be attached with the aid of glue. After the overall assembly, the limit grooves at both ends of the rigid back plate 2 are fixed to the wooden template.

[0019] The rigid skeleton back-attached waterstop structure has an anchoring rubber nail 201 and a rigid back plate 2 on the back of the back-attached rubber waterstop 1. The rigid back plate 2 supports the back-attached rubber waterstop through the anchoring rubber nail 201, thereby strengthening the self-sustainability of the waterstop and improving the flatness and straightness of the installation of the waterstop. In addition, the rigid back plate 2 is combined with the wooden formwork or steel formwork using the limit groove at the end, and the installation is firm, the construction performance is stable, and it is directly connected to the formwork, which improves the installation quality and installation speed. In addition, the rigid back plate 2 increases the strength of the waterstop and avoids damage to the exposed surface.

[0020] The back-sticked rubber waterstop 1 includes a waterstop body, a waterstop strip 101 arranged on the waterstop body, and a telescopic airbag 102 arranged between the waterstop strips 101. The waterstop strip 101 includes a main body and an end portion, and the width of the end portion is greater than the width of the waterstop portion. The structure of the waterstop strip 101 and the telescopic airbag 102 can achieve thermal expansion and contraction when the temperature changes, and can be stably fixed in the construction joint and the deformation joint.

[0021] Preferably, the telescopic airbag 102 is arranged in the middle of the waterstop body, the waterstop strips 101 on both sides are symmetrically arranged, and spacer protrusions are arranged between the waterstop strips 101 and between the waterstop strips 101 and the telescopic airbag 102. The waterstop strips 101, the spacer protrusions and the telescopic airbag 102 are located on the same side of the waterstop body, and the anchoring rubber nails 201 are located on the other side. The spacer protrusions can better stably connect the waterstop body to the concrete.

[0022] In this embodiment, the rigid backboard 2 is an organic hard plastic board, and the edge of the rigid backboard 2 located in the middle part is chamfered, and the limiting groove is preferably an L-shaped groove 202. The L-shaped grooves 202 on both sides of the rigid backboard 2 are spliced ​​with the cast-in-place formwork, and the back can be reinforced with the surrounding purlins of the concrete formwork on both sides.

[0023] The installation method of the rigid skeleton type back-attached waterstop structure of this embodiment is as follows: after the wooden formwork is manually cut into an inverse L-shaped groove 202, it is combined and tightly attached to the L-shaped groove 202 of the rigid backboard 2, and then the surrounding purlin is used for overall reinforcement; after use, the rigid backboard 2 can be removed by cutting off the rubber nails and then removing the backboard; if it has no impact on the surrounding structure, it can also be retained.

[0024] This waterstop structure is mainly used in foundation projects, underground facilities, tunnel culverts, water conveyance aqueducts, retaining dams, etc., which are installed in construction joints and deformation joints when concrete is cast in situ, and are integrated with the concrete structure to ensure the service life of the project construction. A rigid skeleton back-stick waterstop structure and installation method speed up the installation speed and accuracy of the back-stick waterstop on the side wall of the above structure during the construction process, improve the quality and performance of the anti-seepage structure, shorten the process cycle, and have certain innovation and economic value. It also changes the structure of the traditional back-stick rubber waterstop 1, has a certain degree of self-sustainability, fast installation speed, reliable quality, excellent water-stopping performance, and after field tests, it fully meets the construction requirements of anti-seepage structures such as pools and valve wells.

[0025] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0026] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
