Embodiment 1

[0042] Such as figure 1 Shown, a kind of basement floor, exterior wall waterproof construction method, comprises the following steps,

[0043] Step 1: Preparatory work. The preparatory work includes selecting and determining a qualified base surface as a waterproof base, configuring cement mortar, strengthening treatment of detail nodes, and snapping lines and positioning;

[0044] Step 2: Waterproofing membrane construction, including trial laying waterproofing membranes, wet laying waterproofing membranes and quality inspection, repair and acceptance of waterproofing membranes; said wet laying waterproofing membranes also includes laying flat surface waterproofing membranes and equal-span waterproofing membranes. Deformation seam waterproof membrane laying;

[0045] Wherein, the laying of the flat surface waterproof coiled material is laid by a coiled material laying machine, and the coiled material laying machine moves along the direction of laying, automatically releases ...

Embodiment 2

[0060] This embodiment provides a membrane waterproof construction method at the deformation joint.

[0061] In the process of large-scale waterproof construction, deformation joints often appear, and the following treatment methods are used for deformation joints on flat surfaces.

[0062] Such as figure 2As shown, one way of laying the equal-span deformation joint waterproof membrane is: fill the deformation joint with a caulking material 3, and the upper part of the caulking material 3 has a groove 4 and is provided with a foam rod 5. An additional layer of waterproof coiled material 6 is arranged above the foam rod 5, and the additional layer of waterproof coiled material 6 extends symmetrically to both sides and is fixed by closing beading and closing screws 7, and above the additional layer of waterproof coiled material 6 is laid the The waterproof roll material 2 also covers the entire additional layer 6 of the waterproof roll material; the gap between the waterproof ...

Embodiment 3

[0066] This embodiment provides another waterproof construction method of the coiled material at the deformation joint.

[0067] Such as image 3 As shown, another way of laying the equal-span deformation seam waterproof membrane is: the deformation seam is located in the raised structure 9, the caulking material 3 is filled in the deformation seam, and the upper part of the caulking material 3 is left There is a groove 4; a waterproof membrane-201 is laid on the raised structure 9; Connect waterproof roll material 2 202, said waterproof roll material 2 202 is fixed at the lap joint by closing bead and close screw 7; said waterproof roll material 2 202 is folded along the root corner of said protruding structure 9 and set there An additional layer 6 of waterproof roll material; the middle part of the waterproof roll material one 201 is sunken into the groove 4 and a foam rod 5 is arranged above, and a metal rainproof cover plate is also covered above the waterproof roll mater...

Abstract

The invention discloses a waterproof construction method for a basement bottom plate and an outer wall. The waterproof construction method for the basement bottom plate and the outer wall comprises the following steps of S1, carrying out preparation work, specifically, selecting and determining a qualified base surface as a waterproof base layer, preparing cement mortar, reinforcing detail nodes, snapping lines and positioning; S2, carrying out waterproof coiled material construction, wherein the waterproof coiled material construction comprises waterproof coiled material trial paving, waterproof coiled material wet paving and waterproof coiled material quality inspection, repair and acceptance inspection, and the waterproof coiled material wet paving comprises a flat surface waterproof coiled material paving and equal-span deformation joint waterproof coiled material paving; and S3, protecting a finished product after the whole paving is finished. The waterproof construction method for the basement bottom plate and the outer wall is simple and reasonable in step, excellent conditions can be provided for waterproof coiled material paving through early-stage work preparation, and the difficulty and the complexity degree in the subsequent paving construction process are reduced; the waterproof coiled material can be paved with high accuracy and good quality, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of waterproof construction, in particular to a waterproof construction method for a basement floor and an outer wall. Background technique [0002] The leakage of the building floor has become the main quality hidden danger that affects the function of the building. The existing floor waterproofing mostly adopts structural waterproofing combined with modified asphalt waterproofing membranes. After the modified asphalt waterproofing membranes are laid, the protective layer construction is required, and then the floor structure construction is carried out. This method has many layers of structure, the materials are easily damaged, and the quality of the lap joint is not easy to guarantee. It is easy to form a gap between the waterproof layer and the bottom plate structure, and lose the waterproof effect. [0003] Chinese invention patent (notification number: CN104695486B) disclosed a construction method of b...
