Description

Technical Field

[0001] The utility model relates to the technical field of waterstops for building construction, in particular to a waterstop with ribs of special apertures and large deformation amount. Background Art

[0002] In construction projects, waterstops are important components used to prevent moisture penetration, especially at the joints of concrete structures. The performance of waterstops directly affects the waterproofing effect of the building.

[0003] Traditional waterstops have some shortcomings in terms of anchoring security. For example, a weak anchorage can easily lead to waterstop displacement, affecting waterproofing effectiveness. Due to structural design limitations, the connection between the waterstop and concrete relies solely on relatively conventional surface bonding or simple connection methods, resulting in insufficient bite and friction between the two. When a building is subjected to external forces such as foundation settlement and temperature stress changes, the waterstop loses its secure anchoring in the concrete and is prone to displacement.

[0004] To this end, we propose a waterstop with large deformation and special aperture ribs. Utility Model Content

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a waterstop with special aperture ribs and large deformation.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a waterstop with a large deformation amount and a special aperture rib, comprising a main structure, the main structure comprising a waterstop body, the waterstop body being strip-shaped and having a certain thickness and width, the middle portion of the waterstop body being provided with an integrally formed reinforcement rib along its length extension direction, and a central hole being penetrated through the side wall surface of the waterstop body at a position corresponding to the reinforcement rib;

[0007] The top surface and the bottom surface of the waterstop body are both provided with a plurality of groups of convex ribs with a trapezoidal structure.

[0008] Preferably, the outer diameter of the center hole is ≥40 mm, and the inner diameter is ≥25 mm.

[0009] Preferably, a plurality of groups of circular edge ribs are provided on both the left and right sides of the waterstop body, and the diameter of the circular edge ribs is between 20 mm and 30 mm.

[0010] Beneficial effects

[0011] The utility model provides a waterstop with large deformation and special aperture ribs. It has the following beneficial effects:

[0012] (1) This type of waterstop with special aperture ribs and large deformation capacity has an outer diameter of the center hole ≥ 40mm and an inner diameter ≥ 25mm. This allows the waterstop body to effectively release some stress by locally deforming the center hole when facing displacement or deformation of the building structure caused by factors such as temperature changes and foundation settlement. For example, during the thermal expansion and contraction of concrete, the waterstop body can use the elastic deformation of the center hole to buffer the extrusion or tension from the concrete, avoiding tearing or damage caused by stress concentration, greatly ensuring the integrity and effectiveness of the waterstop body in complex deformation environments, extending the service life of the waterstop, and ensuring the long-term stability of its waterstop function.

[0013] (2) This type of waterstop has a large deformation capacity and special aperture ribs. The diameter of the circular ribs on the edge is between 20mm and 30mm, and the shape is similar to a nail cap. This unique shape greatly increases the contact area and friction with the concrete, making the bite between the waterstop and the concrete tighter. At the same time, multiple sets of trapezoidal convex ribs on the top and bottom surfaces further enhance this stabilization effect. The two work together to effectively prevent the waterstop from displacement, falling off, and other problems during concrete pouring or subsequent use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Embodiment: A waterstop with a large deformation amount and special aperture ribs includes a main structure, which includes a waterstop body 1. The waterstop body 1 is strip-shaped and has a certain thickness and width. The waterstop body 1 serves as a basic support part and plays a major role in stopping water at the joints of the building structure, preventing moisture from penetrating along the joints. The middle part of the waterstop body 1 is provided with an integrally formed reinforcement rib 2 along its length extension direction. The reinforcement rib 2 and the waterstop body 1 jointly withstand external pressure and deformation, thereby enhancing the overall strength and stability of the waterstop.

[0022] Among them, a center hole 3 is penetrated and opened at the position of the reinforcing rib 2 on the side wall surface of the waterstop main body 1. The outer diameter of the center hole 3 is ≥ 40 mm, and its inner diameter is ≥ 25 mm. When the building structure is displaced or deformed due to factors such as temperature change and foundation settlement, the waterstop main body 1 needs to adapt accordingly. Through the provided center hole 3, the waterstop main body 1 can release part of the stress by local deformation through the center hole 3 when subjected to stress. For example, during the thermal expansion and contraction of concrete, the waterstop main body 1 uses the elastic deformation of the center hole 3 to buffer the extrusion force or tension from the concrete, avoid tearing or damage caused by stress concentration, and ensure that the waterstop main body 1 can still maintain integrity and effectiveness under complex deformation environments;

[0023] Among them, the top and bottom surfaces of the waterstop main body 1 are provided with multiple groups of trapezoidal convex ribs 4, and the left and right sides of the waterstop main body 1 are provided with edge circular ribs 5, and the diameter of the edge circular ribs 5 is between 20mm-30mm. The combined action of multiple groups of edge circular ribs 5 and the convex ribs 4 improves the firmness of the waterstop main body 1 in the concrete.

[0024] The technical means disclosed in the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
