[0028] In the description of the present invention, "multiple" means at least two, such as two, three, etc., unless otherwise clearly defined. In addition, unless otherwise clearly defined and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0030] The utility model provides a technical solution: a reserved hole structure for a bathroom exhaust duct, which is arranged on a floor slab, and comprises a filling wall 1, a shear wall 2 and a folded plate beam 3, wherein the filling wall 1 is enclosed to form a closed structure, the shear wall 2 is used to separate the closed structure, a reserved hole 5 is opened on the floor slab, and the adjacent two sides of the reserved hole 5 are respectively close to the shear wall 2 and the filling wall 1, and one side of the folded plate beam 3 is close to the reserved hole 5; wherein the filling wall 1, the shear wall 2 and the folded plate beam 3 are enclosed on the floor slab to form a drop plate area 4, a drop plate (not shown) is arranged on the drop plate area 4, and the reserved hole 5 is arranged outside the drop plate area 4, and the elevation surface of the drop plate area 4 is lower than the elevation surface of the reserved hole 5.
[0031] Specifically, this structure is first enclosed by the filling wall 1 to form a closed structure, and then the folded plate beam 3, the filling wall 1 and the shear wall 2 form a lowering plate area 4. Compared with the existing anti-slope structure formed by pouring concrete only around the reserved hole, this area is reduced in area due to the folded plate beam 3 because the original part of the installation of the lowering plate (lowering plate area) is located. In addition, the construction quality of the lowering plate area 4 is also one of the factors affecting leakage, and in many cases it is also the source of leakage. The original anti-slope structure is prone to displacement and deformation, and the use of the folded plate beam 3 can make the overall structure more solid, avoid displacement and deformation, and improve the quality of construction. Therefore, this can not only save the amount of concrete engineering of the anti-slope structure, the amount of waterproof engineering surface and backfilling expanded clay in the lowering plate area, and achieve the effect of reducing costs, improving quality and increasing efficiency, but also reduce the contact area with the source of leakage. In addition, the elevation surface of the drop-plate area 4 is lower than the elevation surface of the reserved hole 5, which has the advantages of improved waterproof performance (the thickness of the waterproof layer is increased accordingly, thereby improving the waterproof performance and reducing the risk of leakage), enhanced installation flexibility (installers have more space to work, which improves the flexibility and convenience of installation), and enhanced structural stability (helps to enhance the structural stability of the floor).
[0032] As an optional implementation, in some embodiments, a high-span plate 6 is provided on the side of the reserved hole 5 away from the shear wall 2, and the high-span plate 6 is higher than the drop plate. In this way, the top elevation of the reserved hole 4 of the exhaust duct can be optimized from the low-span elevation of the drop plate to the elevation of the high-span plate 6. This structure is conducive to preventing leakage and ensuring the waterproof effect of areas such as the bathroom. At the same time, this structure can reduce the load on the building (making the lower layer of the structural floor of the bathroom as a pipeline laying space, reducing the backfill amount), thereby improving safety.
[0033] As an optional implementation, in some embodiments, a drainage pipe groove 7 is further included, one end of which is connected to the drop-down plate area 4, and the other end of which extends out of the filling wall 1, and the drainage pipe groove 7 is arranged near the reserved hole 5. The drainage pipe groove 7 can further prevent water accumulation in the drop-down plate area 4, and the accumulated water can be discharged in time through the drainage pipe groove 7, thereby avoiding leakage caused by the accumulated water.
[0034] As an optional implementation, in some embodiments, the shape of the closed structure is a square. The shape of the closed structure formed by the filling wall 1 can be adjusted according to the structure of the bathroom to meet the installation requirements. Preferably, the closed structure is a square structure, which can meet the installation requirements of most bathrooms.
[0035] In the above embodiment, further, the two ends of the shear wall 2 are fixedly connected to the two opposite inner sides of the closed structure. The structure is loaded by the shear wall 2. At the same time, the shear wall 2 is also a component of the drop-down area 4. No additional components are required, which saves manufacturing materials and reduces costs. In addition, the drop-down area 4 and the reserved hole 5 can be set on both sides of the shear wall 2.
[0036] In the above-mentioned embodiment, further, the shape of the folded plate beam 3 is L-shaped, the shorter side of the folded plate beam 3 is arranged near the reserved hole 5 and fixedly connected to the shear wall 2, and the longer side of the folded plate beam 3 is arranged in a direction away from the reserved hole 5 and fixedly connected to the filling wall 1. Among them, the folded plate beam 3 can adopt different shapes according to the shape of the bathroom, including L-shaped, T-shaped, etc. Preferably, in a square structure, the folded plate beam 3 adopts an L-shape to better cooperate with the filling wall 1 and the shear wall 2, so that the size of the overall structure can be relatively small, which is suitable for places with limited space such as bathrooms, and the design is more reasonable. At the same time, the corners of the L-shaped folded plate beam can be connected to the high-span plate 6 as a whole by means of splicing. This structure makes it overall strong and stable, safe and reliable, so that it can withstand a certain weight and pressure.
[0037] As an optional implementation, in some embodiments, the shear wall 2 is arranged in the middle of the closed structure to divide the closed structure into equal parts. The corresponding drop-down area 4, reserved hole 5 and drainage pipe groove 7 are symmetrically arranged with the shear wall 2 as the axis, and the overall structural design is more beautiful.
[0038] As an optional implementation, in some embodiments, the height difference between the high-span plate 6 and the drop plate is 300 mm. The height difference between the high-span plate 6 and the drop plate can be adjusted according to actual conditions to meet the anti-leakage requirements. Preferably, when the height difference is 300 mm, the anti-leakage effect is better.
