Description

Technical Field

[0001] The utility model belongs to the technical field of water supply and drainage engineering, and specifically relates to a novel inverted "Ω" type drainage ditch and a concrete slab drainage structure using the same. Background Art

[0002] Drainage ditches are often laid out on underground structural layers to collect various water on indoor panels into the sump in time. When the project is large, there are relatively more drainage ditches. If the decoration layer cannot accommodate the drainage ditch, it is necessary to groove the structural layer. At present, most drainage ditches on the market are U-shaped drainage ditches, that is, a U-shaped groove is directly reserved on the bottom plate or a U-shaped groove is embedded in the bottom plate. The width of the U-shaped groove is mostly 300mm, and the depth depends on the situation. The layout of the U-shaped drainage ditch not only cuts off the main horizontal force-bearing steel bars of the structural layer plate, but also lowers the layout of the longitudinal steel bars, reduces the plate thickness, and affects the overall force condition of the structural plate. Therefore, based on the above problems, how to develop and design a drainage ditch that has less impact on the structure is an urgent problem to be solved. Utility Model Content

[0003] The utility model is proposed to solve the problems existing in the prior art, and its purpose is to provide a novel inverted "Ω" type drainage ditch and a concrete slab drainage structure using the same.

[0004] The technical solution adopted by the utility model to solve this problem is:

[0005] A novel inverted "Ω" type drainage ditch, which is an inverted "Ω" water accumulation system composed of an open steel pipe section, inclined steel plate sections symmetrically distributed on both sides of the opening of the open steel pipe section, and horizontal steel plate sections symmetrically distributed on the outside of the inclined steel plate section, which are welded together. The inverted "Ω" water accumulation system is buried in a structure, and its opening is flush with the upper surface of the structure.

[0006] In one technical solution, the open steel pipe section is a stainless steel open steel pipe, the upper end of the stainless steel open steel pipe is open and the opening extends along its extension direction.

[0007] In one technical solution, the inclined steel plate section is a first stainless steel plate, which is welded to both sides of the opening of the stainless steel open steel pipe, and the two first stainless steel plates are arranged in a V-shape with an opening at the bottom.

[0008] In one technical solution, the horizontal steel plate segment is a second stainless steel plate, and the second stainless steel plate is horizontally welded to the stainless steel plate on the same side.

[0009] The second invention object of the utility model is to provide a concrete slab drainage structure using the above-mentioned novel inverted "Ω"-shaped drainage ditch, including an inverted "Ω" water accumulation system and a stress-bearing steel bar system, wherein the structure is a structural concrete slab, the inverted "Ω" water accumulation system and the stress-bearing steel bar system are both arranged in the structural concrete slab, and the stress-bearing steel bar system includes transverse bars in the slab, distributed bars in the slab, and reinforcing bars, wherein:

[0010] The transverse reinforcement in the slab is distributed on both sides of the inverted “Ω” water accumulation system, and its extension direction is parallel to the extension direction of the inverted “Ω” water accumulation system;

[0011] The distribution reinforcement in the slab extends in a direction perpendicular to the extending direction of the inverted “Ω” water accumulation system, and is bent and cut off after encountering the inverted “Ω” water accumulation system;

[0012] The reinforcing ribs are distributed on the lower side of the inverted "Ω" water accumulation system.

[0013] In one technical solution, the structural concrete slab is any load-bearing layer slab of the structure, which is a reinforced concrete structure.

[0014] In one technical solution, the transverse reinforcement in the plate is the main force-bearing reinforcement in the plate arranged parallel to the stainless steel open steel pipe, the first stainless steel plate, and the second stainless steel plate.

[0015] In one technical solution, the in-slab distribution reinforcement is an in-slab distribution reinforcement arranged perpendicular to the extension direction of the inverted "Ω" water accumulation system. The in-slab distribution reinforcement is cut off and bent downward by at least 15 times the length of the reinforcement diameter after encountering a stainless steel open steel pipe or a first stainless steel plate.

[0016] In one technical solution, the reinforcing ribs are reinforcing steel bars in the plate arranged perpendicular to the extension direction of the inverted "Ω" water accumulation system, and the reinforcing ribs are arranged below the stainless steel open steel pipe.

[0017] In one technical solution, the transverse ribs in the slab, the distribution ribs in the slab and the reinforcing ribs are further distributed below the slab bottom transverse ribs.

[0018] The advantages and positive effects of the utility model are:

[0019] 1. The stainless steel open steel pipe in the utility model can be buried deep in the structure. The arrangement of the inverted "Ω" drainage ditch system does not affect the arrangement of the main stress-bearing steel bars in the structure, and has little effect on the stress of the structure. The drainage ditch system minimizes the influence of the additional drainage ditch on the overall stress of the structural plate, and can be widely used in engineering structures, especially suitable for indoor drainage systems.

[0020] 2. The transverse ribs, distribution ribs and reinforcing ribs in the slab in the present invention are steel bars in the slab. The distribution ribs in the slab are bent and cut off after encountering the drainage ditch system. The transverse ribs in the slab are arranged on both sides of the drainage ditch system to participate in the force in the slab and also have the function of fixing the drainage ditch system. The reinforcing ribs are arranged on the lower side of the drainage ditch system to reinforce the distribution ribs that are cut off due to encountering the drainage ditch system.

The stainless steel open steel pipe and the two stainless steel plates are welded into one to form an inverted "Ω" water accumulation system, which is then buried in the structural concrete slab 1. The opening portion thereof is flush with the upper surface of the structural concrete slab. Reinforcing ribs are arranged under the stainless steel open steel pipe in the structural concrete slab. The inverted "Ω" drainage ditch system is wrapped in the structural concrete slab to collect the accumulated water on the slab and quickly discharge the accumulated water. It has high strength, strong stability, simple structure, and is easy to install.

[0034] Furthermore, in this embodiment, it can also be considered that the open steel pipe section is a stainless steel open steel pipe 5, the upper end of the stainless steel open steel pipe 5 is open and the opening extends along the extension direction thereof.

[0035] Furthermore, in this embodiment, it can be considered that the seam width of the opening of the stainless steel open steel pipe 5 is about 75 mm, which can also be adjusted according to the arrangement of the transverse ribs 2 in the plate and the drainage water volume requirement.

[0036] Furthermore, in this embodiment, it can also be considered that the inclined steel plate section is a first stainless steel plate 6, and the first stainless steel plate 6 is welded on both sides of the opening of the stainless steel open steel pipe 5, and the two first stainless steel plates 6 are arranged in a V-shape with an opening at the bottom.

[0037] Furthermore, in this embodiment, it can also be considered that the horizontal steel plate section is a second stainless steel plate 7, and the second stainless steel plate 7 is horizontally welded to the first stainless steel plate 6 on the same side. Figure 1 As shown, two stainless steel plates 6 are welded on both sides of the opening of the stainless steel open steel pipe 5 and arranged in a V shape, and another two stainless steel plates 7 are welded to the stainless steel plates 6 arranged in a V shape in a horizontal state.

[0040] The transverse reinforcement 2 in the plate is distributed on both sides of the inverted "Ω" water accumulation system, and its extension direction is parallel to the extension direction of the inverted "Ω" water accumulation system;

[0041] The distribution reinforcement 3 in the plate has an extension direction perpendicular to the extension direction of the inverted "Ω" water accumulation system, and is bent and cut off after encountering the inverted "Ω" water accumulation system;

[0042] The reinforcing ribs 4 are distributed on the lower side of the inverted "Ω" water accumulation system.

[0043] In this embodiment, Figure 1 As shown, the drainage structure includes a structural concrete slab 1, transverse ribs 2 in the slab, distribution ribs 3 in the slab, reinforcing ribs 4, stainless steel open pipes 5, a first stainless steel plate 6, and a second stainless steel plate 7. Among them: the transverse ribs 2 in the slab and the distribution ribs 3 in the slab are the internal steel bars of the structural concrete slab 1, and the stainless steel open pipes 5 and the first stainless steel plate 6 and the second stainless steel plate 7 are welded together to form an inverted "Ω" drainage ditch system, which is wrapped in the structural concrete slab 1 and used to collect water accumulated on the slab; the transverse ribs 2 in the slab, the distribution ribs 3 in the slab and the reinforcing ribs 4 are the steel bars in the slab, and the distribution ribs 3 in the slab are bent and cut off after encountering the drainage ditch system, and the transverse ribs 2 in the slab are set on both sides of the drainage ditch system to participate in the force in the slab and also have the function of fixing the drainage ditch system, and the reinforcing ribs 4 are set on the lower side of the drainage ditch system to reinforce the distribution steel bars cut off due to encountering the drainage ditch system. The seam width of the opening part of the inverted "Ω" drainage ditch system gradually expands, shrinks, and then expands from bottom to top.
