Description

Technical Field

[0002] The counter-ridge, i.e. the waterproof structure between the roof waterproof layer and the protruding structure, is set up during the construction of the kitchen and bathroom. At present, in order to improve the construction efficiency of the counter-ridge between the kitchen and bathroom, a prefabricated assembled concrete counter-ridge structure is adopted. However, the prefabricated assembled concrete counter-ridge is directly connected to the surface of the floor during construction, and it is also necessary to add sealing and water-stopping components, which not only reduces the assembly stability and firmness of the counter-ridge, but also increases the cost. For example, a prefabricated concrete counter-ridge structure disclosed in Chinese utility model patent announcement number CN217925485U, in which the counter-ridge is directly set on the surface of the floor, and then the connection position is sealed by an additional water-stop plate and a seal, which not only increases the cost, but also requires the slurry to solidify before its position can be fixed. During the slurry pouring or solidification process, the counter-ridge is easily moved due to external force, which reduces its assembly stability and firmness. Utility Model Content

[0029] See also Figure 1-3 On one hand, an embodiment of the present application provides a prefabricated assembled concrete counter-ridge structure, which is mainly used in the floor slab 3 structure, and mainly includes a prefabricated counter-ridge 1 and a prefabricated base 2. The prefabricated counter-ridge 1 has a grouting port 12, and the prefabricated counter-ridge 1 is sealed and fixedly connected to the top surface of the prefabricated base 2; the bottom surface of the prefabricated base 2 is provided with (at least one) guide groove along the length direction, and the prefabricated base 2 is provided with a connecting hole 23, and the upper and lower ends of the connecting hole 23 are respectively connected to the grouting port 12 and the guide groove. A reserved groove 31 is reserved or opened in advance on the surface of the floor slab 3, and the prefabricated base 2 is embedded in the reserved groove 31, and slurry is poured into the cavity formed by the guide groove and the reserved groove 31. The above-mentioned prefabricated assembled concrete counter-step structure is designed with a reserved groove 31 on the floor slab 3, and the prefabricated base 2 can be directly placed in the reserved groove 31 to achieve rapid fixation of the prefabricated counter-step 1 and the prefabricated base 2; and a grouting port 12 is opened on the prefabricated counter-step 1, and a guide groove and a connecting hole 23 are opened on the prefabricated base 2. The slurry is poured into the grouting port 12 and enters the guide groove through the connecting hole 2. The slurry is poured into the guide groove to achieve a stable connection between the prefabricated base 2 and the floor slab 3, which greatly improves the assembly stability and firmness of the counter-step. At the same time, a step is formed at the connection between the floor slab 3 and the counter-step to improve the waterproof and water-stopping effect.

[0030] In some embodiments, in order to improve the integrity and waterproofness of the prefabricated counter-ridge 1 and the prefabricated base 2, the prefabricated counter-ridge 1 and the prefabricated base 2 can be prefabricated as a whole using reinforced concrete.

[0031] In some embodiments, in order to facilitate the injection of slurry, a trumpet-shaped pouring trough 11 can be set at the upper end of the grouting port 12 to enlarge the opening and facilitate grouting; the grouting port 12 is located in the middle of the prefabricated anti-ridge 1, is long and strip-shaped, arranged along the length direction, and penetrates from top to bottom.

[0032] In some embodiments, the guide groove is designed to be a long strip, arranged along the length direction of the prefabricated base 2, and runs through the entire bottom surface of the prefabricated base 2, that is, the same length as the prefabricated counter-ridge 1 and the prefabricated base 2, increasing the casting surface to facilitate the flow and uniform distribution of the casting slurry.

[0033] In some embodiments, the bottom surface of the prefabricated base 2 is provided with n guide grooves, where n is an integer greater than or equal to 3. The guide groove located in the center is a first guide groove 24, and the guide grooves located on both sides are second guide grooves 26. The first guide groove 24 is connected to the connection hole 23. A first connecting groove 25 is provided between the first guide groove 24 and the second guide groove 26. A first connecting groove 25 is provided between adjacent second guide grooves 26, further increasing the casting area and improving the assembly stability, firmness, and waterproofness of the counter-slope.

[0034] Specific to Figure 3 In the illustrated embodiment, a first guide groove 24 and two second guide grooves 26 are included. The second guide grooves 26 are symmetrically arranged on both sides of the first guide groove 24 to ensure balanced force.

[0035] Furthermore, a second connecting groove 27 is provided on the outer side wall of the second guide groove 26 located on the outermost side, so as to facilitate the slurry to flow into the gap between the side wall of the prefabricated base 2 and the side wall of the floor slab 3, thereby further increasing the firmness of the connection.

[0036] In some embodiments, a clearance fit is formed between the prefabricated base 2 and the reserved groove 31 to facilitate smooth insertion of the prefabricated base 2 into the reserved groove 31. A positioning block 4 is inserted into the gap between the prefabricated base 2 and the reserved groove 31. The side of the positioning block 4 contacts and squeezes the inner wall of the side of the reserved groove 31. The positioning block 4 pre-fixes the installation position of the sealing base 2 through the horizontal squeezing force with the reserved groove 31.

[0037] Specific to Figure 1 In the illustrated embodiment, the positioning block 4 is L-shaped, the insertion end 41 of the positioning block 4 is a wedge-shaped structure, and the positioning block 4 is a prefabricated concrete component or a wooden block.

[0038] Furthermore, a groove 22 is provided on the side of the sealing base 2 , and the positioning block 4 is inserted into the groove 22 for limiting the position of the positioning block 4 .

[0039] Furthermore, a limiting groove 21 is provided at the groove 22. The depth of the limiting groove 21 is greater than the thickness of the horizontal edge of the positioning block 4. The horizontal edge of the positioning block 4 is embedded in the limiting groove 21 to prevent the positioning block 4 from protruding from the surface of the sealing base 2 and maintain flatness.

[0040] In summary, during the construction of the prefabricated assembled concrete anti-ridge structure:

[0041] First, place the counter-sill body 1 and the sealing base 2 into the reserved groove 31, then insert the positioning block 4 downward into the reserved groove 31, and then hit it downward with a hammer so that the upper end of the positioning block 4 is inside the limiting groove 21. At this time, the positioning blocks 4 set on both sides of the sealing base 2 are simultaneously squeezed toward both sides of the sealing base 2, thereby pre-positioning the sealing base 2 (and the counter-sill body 1);

[0042] The slurry is then poured into the connecting hole 23 through the pouring trough 11 and the grouting port 12, and then filled into the bottom of the sealing base 2 and the reserved groove 31 through the first guide groove 24, the first connecting groove 25, the second guide groove 26 and the second connecting groove 27. After the poured slurry solidifies, the connection of the anti-ridge is sealed and fixed.

[0043] By setting up the sealing base 2, the reserved groove 31 and the pre-positioning block 4, the prefabricated counter-ridge can be quickly fixed, which greatly improves the assembly stability and firmness of the counter-ridge. In addition, the sealing slurry can be evenly filled through the set guide groove and connecting groove, thereby sealing the counter-ridge joints and reducing costs.
