Abstract
Description
Technical Field
[0001] The present application relates to the technical field of drainage construction, and in particular to a drainage structure at the basement column foot or wall foot position. Background Art
[0002] At present, when dealing with the waterproofing problem of basement slabs in many civil and industrial buildings, the idea of combining drainage, water storage and water blocking is adopted, and the basement HDPE green drainage system is used for waterproofing; during construction, HDPE drainage boards are laid on the basement slabs. The HDPE drainage boards are concave and convex hollow rib structures. The water on the lower side of the HDPE drainage boards is blocked and diverted to the drainage pit in the low-lying area through the drainage boards. After a period of time, concrete is poured on the HDPE drainage boards to complete the construction of the basement slabs. At present, during the construction of basement drainage, most of the drainage boards are laid directly to the column foot or wall foot, and the side of the drainage board is directly in contact with the column foot or wall foot, resulting in the formation of seepage gaps between the side of the drainage board and the column foot or wall foot. The water on the lower side of the drainage board flows up to the upper side of the drainage board through the gap, affecting the drainage effect. Utility Model Content
[0003] The utility model aims to solve the problem that water on the lower side of the drainage board surges up from the gap due to the presence of a gap at the overlap position of the drainage board and the column foot or the wall foot, thereby providing a drainage structure for preventing water from seeping into the gap between the drainage board and the column foot or the wall foot in the basement.
[0004] The utility model solves the above problems and adopts the following technical solutions:
[0005] A drainage structure at the basement column foot or wall foot position is applied to the basement floor, including a drainage board laid on the basement floor, the side of the drainage board close to the column foot or wall foot is arranged at a designed distance from the column foot or wall foot, a concrete cushion layer is cast at the column foot or wall foot position, the side of the drainage board close to the column foot or wall foot is pressed into the concrete cushion layer, and the side of the drainage board away from the column foot or wall foot extends to above the sump.
[0006] Compared with the prior art, the utility model adopting the above technical solution has the following beneficial effects:
[0007] The utility model arranges a concrete cushion layer at the position of the column foot or the wall foot. When the drainage board is laid, one side of the drainage board close to the column foot or the wall foot is pre-buried in the concrete cushion layer, so that there is no seepage gap between the drainage board and the column foot or the wall foot, and water on the lower side of the drainage board is prevented from surging up through the overlap gap between the drainage board and the column foot or the wall foot, thereby affecting the drainage effect.
[0008] As a preferred embodiment, a further technical solution of the utility model is:
[0009] Several anchors are set in the concrete cushion at equidistant positions of the column foot or wall foot. The lower part of the anchor is fixed to the basement floor, and the upper part of the anchor is bent toward the side of the drain board, and the bent outer end is used to abut against the drain board inside the concrete cushion. The anchor is used to fix the position of the drain board in the concrete cushion to prevent the drain board from moving due to concrete shrinkage or water flow, which affects the fixing effect of the drain board and the concrete cushion.
[0010] The length of the drainage board near the column foot or wall foot embedded in the concrete cushion is 50mm-
[0011] 100mm. Through the above structure, the drainage board and the concrete cushion layer are fixed more firmly.
[0012] The anchor includes a fixing rod, an arc rod and a crimping block. The fixing rod is arranged perpendicular to the basement floor. One end of the arc rod is fixed to the top of the fixing rod, and the other end of the arc rod is fixed to the crimping block. The crimping block is used to abut against the drainage board inside the concrete cushion layer.
[0013] The shape and size of the compression block and the concave point of the drain board are the same, and the compression block is used to abut against one concave point of the drain board in the concrete cushion layer. Through the above structure, the compression block can fix the part of the drain board located in the concrete cushion layer more firmly.
[0014] The crimping block is made of rubber material to avoid damage caused by hard contact between the crimping block and the drain board. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.
[0022] Reference Figure 1-5 , the embodiment of the present application discloses a drainage structure at the position of a basement column foot or wall foot, which is applied to the basement floor 5, including a drainage board 1 laid on the basement floor 5, and the distance between the side of the drainage board 1 close to the column foot 2 or the wall foot 6 and the column foot 2 or the wall foot 6 is 100mm-200mm. Preferably, the drainage board 1 is laid to a position with a distance of 100mm from the column foot 2 or the wall foot 6, and a concrete cushion layer 4 is poured at the position of the column foot 2 or the wall foot 6. Preferably, the concrete cushion layer 4 adopts high-strength concrete with a strength of C60 or more to increase the concrete strength and stability at the position of the column foot 2 or the wall foot 6; during installation, the side of the drainage board 1 close to the column foot 2 or the wall foot 6 is pre-buried in the concrete cushion layer 4, and the side of the drainage board 1 away from the column foot 2 or the wall foot 6 extends to the top of the sump;
[0023] In this embodiment, a plurality of anchors 3 are arranged in the concrete cushion layer 4 at equidistant positions of the column foot 2 or the wall foot 6, and each anchor 3 is spaced at a certain interval. Preferably, the interval between each fixing rod 31 is set to 200 mm, and the lower part of the anchor 3 is fixed to the basement floor 5, and the upper part of the anchor 3 is bent toward the side of the drainage board 1, and the bent outer end is used to abut against the concave point of the drainage board 1 inside the concrete cushion layer 4 closest to the wall foot 6 or the column foot 2. Preferably, the height of the fixing rod 31 in the basement floor 5 exceeds 50 mm to increase the stability of the fixing rod 31.
[0024] In this embodiment, the length of the drain board 1 near the column foot 2 or the wall foot 6 is embedded in the concrete cushion 4 by 50 mm to 100 mm. Preferably, the drain board 1 near the column foot 2 or the wall foot 6 is embedded in the concrete cushion 4 by 50 mm. Through the above structure, the connection between the drain board 1 and the concrete cushion 4 is more firmly established.
[0025] In this embodiment, the anchor 3 includes a fixing rod 31, an arc rod 32 and a crimping block 33. The fixing rod 31 is arranged perpendicular to the basement floor 5. One end of the arc rod 32 is fixed to the top of the fixing rod 31, and the other end of the arc rod 32 is fixed to the crimping block 33. The crimping block 33 has the same shape and size as the concave point of the drain board 1. The crimping block 33 is used to abut the concave point of the drain board 1 in the concrete cushion layer 4, which is closest to the wall foot 6 or the column foot 2. Preferably, the fixing rod 31 and the arc rod 32 are integrally formed with steel bars, and can be made using the remaining steel bars at the construction site. When the crimping block 33 abuts against the concave point, the outer end of the arc rod 32 is pressed downward to make the crimping block 33 abut against the concave point more stably. Through the above structure, the position of the drain board 1 in the concrete cushion layer 4 is fixed to avoid the drain board 1 from being deviated when the concrete solidifies and shrinks in the later stage, or the water flow under the drain board 1 drives the drain board 1 to move, which affects the anchoring effect of the drain board 1 and the concrete cushion layer 4.
[0026] In this embodiment, the pressing block 33 is made of rubber material to avoid damage caused by hard contact between the pressing block 33 and the drain plate 1.
[0027] The utility model sets a concrete cushion layer 4 at the position of the column foot 2 or the wall foot 6. When the drain board 1 is laid, the side of the drain board 1 close to the column foot 2 or the wall foot 6 can be pre-buried in the concrete cushion layer 4, so as to avoid the appearance of seepage gaps between the drain board 1 and the concrete cushion layer 4, and to avoid the water on the lower side of the drain board 1 from surging up through the overlapping seepage gaps between the drain board 1 and the column foot 2 or the wall foot 6; the position of the drain board 1 located in the concrete cushion layer 4 is fixed by the fixing rod 31 and the arc rod 32, so as to avoid the drain board 1 from moving under the influence of the water flow. At the same time, when the concrete solidifies and shrinks in the later stage, the drain board 1 will not be driven to deviate, thereby affecting the fixing effect of the drain board 1 and the concrete cushion layer 4.
[0028] During actual construction, when constructing the basement floor 5, the fixing rods 31 are pre-buried in the basement floor, and the distance between each fixing rod 31 and the wall foot 6 or the column foot 2 is preferably set to 30 mm. The highest point of the arc rod 32 at the top of the fixing rod 31 is no more than 6 mm away from the basement floor 5. The drainage board 1 is laid on the basement floor 5, and 100 mm is reserved near the column foot 2 or the wall foot 6 without laying the drainage board 1. Concrete is poured at the position of the column foot 2 or the wall foot 6, close to the column foot 2 or the wall foot 6, to form a concrete cushion layer 4. The width of the concrete cushion layer 4 is cast to be 150 mm, and the thickness of the concrete cushion layer 4 is cast to be 8 mm. Make the fixing rod 31 and the arc rod 32 completely located in the concrete cushion layer 4. When the concrete cushion layer 4 has not solidified, embed the side of the drainage board 1 close to the wall foot 6 or the column foot 2 into the concrete cushion layer 4 with a length of 50 mm, and abut the crimping joint of the anchor 3 against the innermost concave point of the drainage board 1, and press the outer end of the arc rod 32 downward to increase the stability of the fixed drainage board 1. After the concrete cushion layer 4 solidifies, the concrete cushion layer 4 fits tightly with the column foot 2 or the wall foot 6, and there is no water seepage gap. The water on the basement floor 5 is drained to the low sump through the space under the drainage board 1 outside the concrete cushion layer 4.
[0029] The above description is only a preferred feasible embodiment of the present utility model, and does not limit the scope of rights of the present utility model. All equivalent changes made using the contents of the present utility model specification and its drawings are included in the scope of rights of the present utility model.
