Description

Technical Field

[0001] This utility model relates to a guide wall side joint, and more particularly to a leak-proof guide wall side joint. Background Technology

[0002] Currently, a concrete guide wall needs to be poured for the secondary structure on the water-facing side of the site. The height of the guide wall is determined according to the design drawings and is generally ≥200mm. During the construction process, the construction unit will usually roughen the interface between the new and old concrete at the bottom of the guide wall to prevent leakage at the bottom.

[0003] However, for some structural forms, such as balcony slabs, guide walls also need to be poured. In this case, there is also a bonding surface on the side of the newly poured guide wall. Often, the construction unit neglects to treat the bonding surface between the old and new concrete on the side, and only performs simple roughening. After project verification, this approach is not ideal when conducting water spray tests, with a leakage rate of over 60%. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a seepage-proof guide wall side joint that can not only effectively prevent leakage at the joint surface, but also has high overall strength and sealing performance, simple structure, and is easy to construct and maintain.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a seepage-proof guide wall side joint, including water-facing concrete and concrete guide wall, with steel bars embedded at the joint surface of the water-facing concrete and concrete guide wall, and a waterproof coating layer applied to the joint above the joint surface, wherein the strength grade of the concrete guide wall is greater than that of the water-facing concrete.

[0006] Furthermore, two steel bars are inserted at the interface between the water-facing concrete and the concrete guide wall, with each steel bar having an insertion depth of 10d and not less than 100mm, and a reserved bar length of 500mm.

[0007] Furthermore, the steel bar is of type HRB400 and has a diameter of Φ6.

[0008] Furthermore, the waterproof coating layer is a JSⅡ type waterproof coating layer.

[0009] Furthermore, the JSⅡ type waterproof coating layer has a thickness of 5mm and a width of 200mm.

[0010] Furthermore, the concrete guide wall is C25 concrete, and the concrete on the water-facing side is C20 concrete.

[0011] Compared with the prior art, the present invention has the following advantages: The anti-seepage guide wall side joint provided by the present invention uses concrete of different strengths and is combined with embedded steel bars and waterproof coating layers, which can not only effectively prevent leakage at the joint surface, but also has high overall strength and sealing performance, simple structure and easy construction and maintenance.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Figure 1 This is a schematic diagram of the side seam structure of the anti-leakage guide wall of this utility model; Figure 2 This is a schematic diagram of the anti-leakage guide wall side seam of this utility model used in a balcony slab structure.

[0016] Please see Figure 1 and Figure 2 The anti-seepage guide wall side joint provided by this utility model includes a water-facing concrete 1 and a concrete guide wall 2. A reinforcing bar 4 is embedded at the joint surface 3 of the water-facing concrete 1 and the concrete guide wall 2. A waterproof coating layer 5 is applied to the joint above the joint surface 3. The strength grade of the concrete guide wall 2 is greater than that of the water-facing concrete 1. Preferably, the concrete guide wall 2 is C25 concrete, and the water-facing concrete 1 is C20 concrete.

[0017] In a preferred embodiment, two reinforcing bars 4 are inserted at the interface 3 between the water-facing concrete 1 and the concrete guide wall 2. The insertion depth of each reinforcing bar 4 is 10d and not less than 100mm, and the reserved bar length is 500mm. The reinforcing bar 4 is of type HRB400 and has a diameter of Φ6.

[0018] In a preferred embodiment, the waterproof coating layer 5 is a JSⅡ type waterproof coating layer. The JSⅡ type waterproof coating layer has a thickness of 5mm and a width of 200mm.

[0019] The anti-seepage guide wall side joint provided by this utility model uses concrete of different strengths, combined with embedded steel bars and a waterproof coating layer. It not only effectively prevents leakage at the joint surface but also has high overall strength and sealing performance. The structure is simple and easy to construct and maintain. Specific construction and application are as follows:

[0020] For the construction of concrete guide walls with side joints, the base surface should be thoroughly cleaned before construction. The bottom and side joints should be roughened according to standard procedures. For the side joints, rebar should be installed at point 3 on the joint surface, using two Φ6 (HRB400) rebars at a depth of 10d and not less than 100mm, with a reserved rebar length of 500mm. After the formwork is completed, guide walls are generally poured with C20 concrete; however, a higher grade, C25 concrete, will be used here. Finally, after demolding, a 5mm thick layer of JSⅡ type waterproof coating, 200mm wide, should be applied to the joints.

[0021] After taking the above measures, the water spray test at the joint surface showed no leakage, demonstrating significant effectiveness.

[0022] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
