Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
As shown in fig. 1, in a preferred embodiment of the present invention, there is provided a hydrophobic and moisture-proof structure for basement floor, the basic structure of which comprises hydrophobic plate 3, reinforcing mesh 4 and concrete surface 5. This kind of basement, concrete bottom plate 2 sets up on concrete cushion 1, has seted up escape canal 6 along concrete side wall 7. Wherein, hydrophobic plate 3 is tiled above basement bottom plate 2. For ease of manufacture and use, each hydrophobic sheet 3 has a certain width and can be manufactured in roll form. Referring to fig. 2, the upper surface of the whole basement bottom plate 2 is continuously overlapped by a plurality of hydrophobic plates 3 to form a whole covering the surface of the basement bottom plate 2.
Referring to fig. 3, each hydrophobic plate 3 is not in a planar form, but a plurality of hydrophobic plate feet 32 are arranged on the plate surface in a rectangular array form, each hydrophobic plate foot 32 protrudes downwards from the plate surface, and the bottom surfaces of all the hydrophobic plate feet 32 are on the same plane, so that the whole hydrophobic plate 3 is stably supported on the basement bottom plate 2 through each hydrophobic plate foot 32. The adjacent hydrophobic plate feet 32 have a certain distance, so when the hydrophobic plate 3 is placed on the upper surface of the basement bottom plate 2, the hydrophobic channel 31 is formed between the adjacent two hydrophobic plate feet 32. Each of the drainage channels 31 formed by the drainage plate feet 32 should communicate with the drain 6 in the basement so that water collected in the drainage channel 31 can drain along the drain 6 into the sump.
The hydrophobic plate 3 is made of hydrophobic materials, and the material and the size parameters of the hydrophobic plate can be adjusted according to actual conditions. In this embodiment, the manufacturing cost and the use effect are considered comprehensively, the hydrophobic plate 3 can be made of hydrophobic PVC material, the thickness of the material is not less than 0.2mm, and the hydrophobic plate 3 is a single coiled material with the width not less than 1800 mm.
In addition, as shown in fig. 4, since the hydrophobic plate 3 needs to bear the upper load, the hydrophobic plate 3 may be provided with criss-cross stiffening ribs 33 to increase the overall rigidity of the hydrophobic plate and reduce the deformation of the hydrophobic plate 3 during use.
The shape and the size of the drain board feet 32 arranged on the drain board 3 can be adjusted according to actual needs, and the height of the drain board feet 32 can be set to be 10-20 mm in the embodiment; in the array of hydrophobic plate feet 32, the distance between adjacent hydrophobic plate feet 32 in the transverse direction and the longitudinal direction is not more than 50 mm. In addition, referring to fig. 5, the cross section of the hydrophobic plate foot 32 in this embodiment may be arranged in a petal shape, and the cross section area decreases from top to bottom. The trap foot 32 with the shape is provided with a plurality of petal-shaped bulges 34, so that the rigidity of the trap foot 32 can be increased, and the bearing capacity of the trap foot can be improved.
Because the hydrophobic plate feet 32 are arranged on the hydrophobic plates 3, the adjacent hydrophobic plates 3 are lapped by adopting a groove buckling mode, namely the hydrophobic plate feet 32 on the lapping side of one hydrophobic plate 3 are clamped into the grooves of the hydrophobic plate feet 32 on the lapping side of the other hydrophobic plate 3, and the splicing of the hydrophobic plate feet and the hydrophobic plate feet is realized. In order to ensure the firmness of the splicing part, the overlapping part of the adjacent hydrophobic plates 3 is not less than the width of 2 hydrophobic plate feet 32.
In addition, the hydrophobic plate 3 is not directly exposed for use, and a concrete surface layer 5 needs to be poured above the hydrophobic plate 3 for protection and decoration. Referring to fig. 1, the concrete surface 5 is poured over the hydrophobic plate 3 and is required to be filled with each hydrophobic plate foot 32, and the top surface of the concrete surface 5 is leveled and kept flat. In order to reinforce the structural strength of the concrete surface layer 5, a mesh reinforcement 4 can be laid therein, wherein the mesh reinforcement 4 is generally arranged on the middle of the layer body of the concrete surface layer 5 in a plane, and the upper and lower layers are provided with concrete layers.
The concrete material and specification of the concrete surface 5 and the reinforcing mesh 4 can be selected according to the corresponding design requirements. In this embodiment, the concrete surface 5 is formed by pouring fine stone concrete, and the reinforcing mesh 4 is a single-layer bidirectional reinforcing mesh with a thickness of 4-6.5 mm, and the thickness of the concrete surface 5 poured thereon should not be less than 30 mm.
Based on the above, the utility model provides a concrete construction method of this basement bottom plate hydrophobic dampproofing structure as follows:
step 1: the basement bottom plate surface is cleaned, the surface is required to be flat and smooth, and the phenomena of looseness, sanding, hollow and bulging and the like cannot exist.
Step 2: lay PVC drain board coiled material overlap joint in proper order on the basement bottom plate, the width of two drain board feet of overlap joint between the adjacent drain board, every certain area of laying should adopt grout to live the drain board of having laid fixedly, prevent that the drain board from removing the stick-up limit, if there is the structure escape canal, lay the drain board to the escape canal border, if need set up the building escape canal, lay and should break off to building escape canal position drain board to reserve building escape canal position.
And step 3: uniformly filling the plate feet of the PVC hydrophobic plate with C20 fine stone concrete, leveling with a straight rod, and controlling the height of the concrete to be 10-20 mm higher than the surface of the hydrophobic plate.
And 4, step 4: and (3) when the strength of the fine stone concrete in the step (3) reaches 70% of the designed strength, binding a phi 6@200 single-layer bidirectional reinforcing mesh and placing the mesh on the fine stone concrete, continuously pouring C20 fine stone concrete with the thickness of 40mm, after the strength reaches 70% of the designed strength, checking whether the drainage channel at the drainage ditch is blocked by the concrete, and if the channel is blocked, dredging in time.
And 5: the above is a specific implementation scheme for preventing the basement of the newly-built building from leaking, if the existing building has the problem of cracking and leaking of the bottom plate, when the clear height of the building meets the requirement, the surface layer of the original building is not removed, and the hydrophobic plate can be directly laid after the surface layer is cleaned; if the building clear height of the laid hydrophobic plate does not meet the requirement, the original building surface layer is firstly removed, the surface is guaranteed to be smooth and clean, then the hydrophobic plate is laid according to the steps, and steel bars are bound and concrete is poured.
In the using process, because the concrete surface layer is separated from the bottom plate concrete, the crack of the bottom plate concrete cannot be reflected upwards, and the newly poured concrete surface layer cannot generate structural cracks; in addition, the PVC hydrophobic plate has certain flexibility, and can not crack even if slightly deformed under the action of external load, so that the normal use of the hydrophobic plate can not be influenced.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
