Description

Technical Field

[0001] The invention relates to the technical field of basement construction, and more particularly to a method for constructing a wall-mounted drainage ditch on a basement floor. Background Art

[0002] Group buildings are usually connected to the basement, with a large floor area. During use, they often encounter moisture or water leakage. If drainage ditches are not designed, it will be difficult to deal with them. Water leakage is easy to form at the root of the wall. Without affecting the use function, the construction unit often adds some shallow drainage ditches against the wall. The drainage ditch construction usually adopts wooden or steel formwork. Generally, holes are drilled on the bottom plate on both sides of the formwork and then steel bars are inserted. The inner and outer steel bars clamp the formwork. Drilling holes in the bottom plate can easily cause water leakage in this area, and it is not convenient to remove the formwork. If the brick formwork is used for formwork, the labor and material costs are high. Summary of the invention

[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a method for constructing a basement floor wall drainage ditch, which can efficiently and conveniently carry out drainage ditch construction, is simple to operate, has low cost, and is not prone to water leakage.

[0004] The present invention adopts the following technical solution:

[0005] A method for constructing a basement floor wall drainage ditch comprises the following steps:

[0006] Draw the ink fountain line along the outside of the wall, and at the same time draw the drainage ditch on the wall to complete the surface line;

[0007] Use multiple extruded polystyrene boards to fit closely to the exterior wall panels, and use cement mortar to fix the inner side of the extruded polystyrene boards;

[0008] Pour the floor concrete, then remove the extruded polystyrene panels on the inside of the gutter;

[0009] After the drainage ditch is formed, cement mortar is applied inside the ditch, sloping towards the nearest water collection well.

[0010] Furthermore, the distance between the ink fountain line and the exterior wall panel is 100 mm.

[0011] Furthermore, the number of the extruded polystyrene boards is 2, and the thickness of the extruded polystyrene boards is 50 mm.

[0012] Furthermore, the cross-section of the cement mortar for fixing the extruded polystyrene board is triangular, that is, wide at the bottom and narrow at the top, and the upper end of the mortar is flush with the finished surface.

[0013] Furthermore, the extruded polystyrene board in the drainage ditch is removed after the concrete has finally set.

[0014] Furthermore, the method for dismantling the extruded polystyrene board is to first dismantle the extruded polystyrene board against the wall, and then dismantle the other extruded polystyrene boards.

[0015] Beneficial Effects

[0016] The present invention adopts extruded polystyrene board and mortar for formwork. Compared with traditional wooden formwork or steel formwork, the present invention does not need to drill holes on the bottom plate for reinforcement, thereby reducing the hidden danger of water leakage.

[0017] Compared with the traditional wooden mold or steel mold, the present invention is more convenient to remove the mold.

[0018] Compared with the brick formwork, the present invention is more economical and saves costs.

[0019] Compared with the traditional wooden or steel mold, the invention is more convenient to install, does not require mechanical equipment, and has lighter materials. The invention can be completed by the bricklaying work without the cooperation of the carpenter, and can be completed synchronously when the ash cake is made. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 This is a schematic diagram of an embodiment of the present invention after construction;

[0021] Figure 2 The present invention is a construction flow chart of an embodiment. DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] As shown in the figure, the present invention discloses a method for constructing a basement floor wall drainage ditch, comprising the following steps:

[0024] Draw a line on the bottom plate 1 along the outside of the wall to ensure that the drainage ditch is straight, and at the same time, draw a drainage ditch on the wall surface of the outer wall 2 to complete the surface line;

[0025] Multiple extruded polystyrene boards 5 are used to closely adhere to the exterior wall panels. The arrangement of multiple extruded polystyrene boards is convenient for adjustment and removal. The inner side of the extruded polystyrene board is fixed with cement mortar 4;

[0026] Pour the floor concrete to form the floor 3, and then remove the extruded polystyrene board 5 on the inner side of the drainage ditch;

[0027] After the drainage ditch is formed, cement mortar is applied inside the ditch, sloping towards the nearest water collection well.

[0028] In one embodiment of the present invention, the distance between the ink fountain line and the exterior wall panel is 100 mm.

[0029] In one embodiment of the present invention, there are two extruded polystyrene boards, and the thickness of the extruded polystyrene boards is 50 mm. The specific number of extruded polystyrene boards is related to the distance between the ink fountain line and the exterior wall board, and the sum of the thicknesses of the extruded polystyrene boards is equal to the distance between the ink fountain line and the exterior wall board.

[0030] In one embodiment of the present invention, the cross-section of the cement mortar 4 for fixing the extruded polystyrene board is triangular, that is, wide at the bottom and narrow at the top. The structure of the cement mortar here ensures stability, and the upper end of the mortar is flush with the finished surface.

[0031] In one embodiment of the present invention, the extruded polystyrene board in the drainage ditch is removed after the concrete is finally set.

[0032] In one embodiment of the present invention, the extruded polystyrene board is removed by first removing the extruded polystyrene board 5 against the wall, and then removing the other extruded polystyrene boards 5. Since there are multiple extruded polystyrene boards in the present invention, it is very convenient to remove them.

[0033] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
