But has the defects of long construction period, high labor cost, material waste and the like. The utility model provides a construction method for a water-proof coiled material internal corner additional layer, which adopts a finished product water-proof additional layer. The finished waterproof additional layers are tightly attached to the wall surfaces on the two sides of the internal corner and the external corner. The waterproof device can achieve a good waterproof effect, and meanwhile, the working efficiency is improved, and the cost is reduced.

Technical problem to be solved
Aiming at the defects of the prior art, the utility model provides an additional layer structure for the internal corner of a waterproof roll, which solves the problems of long construction period, high labor cost, material waste and the like of the existing waterproof roll construction structure.
(II) technical scheme
In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a be used for waterproofing membrane reentrant corner additional layer structure, includes wall body and ground, the crossing department in wall body and ground has the reentrant corner, the reentrant corner has set gradually convex panel of stereoplasm, additional layer, waterproofing membrane from inside to outside, waterproofing membrane's both ends are provided with the coating of building a border, the coating of building a border is provided with waterproof coating outward.
Preferably, the bridging coating is a bridging adhesive tape.
Preferably, the bridging coating is polyurethane caulking.
Preferably, the waterproof coating is a polyurethane coating film.
Preferably, the contact surfaces of the hard arc-shaped plate and the additional layer, and the contact surfaces of the additional layer and the waterproof roll are arc surfaces.
(III) advantageous effects
The utility model provides an internal corner additional layer structure for a waterproof roll. The method has the following beneficial effects:
this be used for waterproofing membrane reentrant corner additional layer structure through pasting the convex panel of finished product stereoplasm (adopting 801 glue to paste) at reentrant corner position and replacing traditional fillet or 45 splayed feet, can increase reentrant corner position and waterproofing membrane combination effect effectively through this medium to reach the emergence that reduces the hollowing quality problem of coiled material.
Drawings
FIG. 1 is a schematic view of the structure of the present invention.
In the figure: 1. a wall body; 2. hard circular arc-shaped plates; 3. an additional layer; 4. waterproof coiled materials; 5. a bridging coating; 6. and (3) a waterproof coating.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to the utility model, the hard arc-shaped plate (adhered by 801 glue) of the finished product is adhered to the internal corner part to replace the traditional round corner or 45-degree splayed foot, so that the combination effect of the internal corner part and the waterproof coiled material can be effectively improved through the medium, and the problem of hollowing quality of the coiled material is reduced.
The concrete construction process is as follows:
1. base layer treatment: the base layer is cleaned without floating, sinking, sundries and water.
2. Strengthening treatment of node parts: and (3) adhering a hard arc-shaped plate (firmly adhered by adopting 801 glue) at the internal corner until the strength is reached (no obvious depression is formed when the hand is pressed downwards).
3. Laying an additional layer: and (4) paving a corner reinforcing layer on the internal corner, wherein the width of the reinforcing layer is not less than 500mm, and the two sides of the reinforcing layer are 250mm respectively.
4. Laying waterproof rolls: the lap width of the web seam was 100 mm. When the coiled material is pasted, firstly, the lapping parts are temporarily fixed by adhesive every 50-100 cm, the lapping seams of the coiled material are pasted after a large-area coiled material is laid, the prepared adhesive is uniformly coated on two bonding surfaces of an opened coiled material joint by a paint brush (the coating amount is preferably 0.5-0.8 kg/m 2), then, the two bonding surfaces are dried for 20-30 min, the two bonding surfaces can be bonded when the hand feeling is not sticky, air is expelled from one end while pressing, so that no air bubbles and wrinkles exist, finally, small handheld iron rollers are used for sequentially rolling once, then, the adhesive is used for pasting a coiled material adhesive tape along the lapping seams of the coiled material, a pressing roller is used for rolling to enable the pasting to be firm, and two side edges of the coiled material adhesive tape are sealed by using double-component polyurethane sealant. Where the other part of the web is three-ply folded it must be closed with a polyurethane sealant.
5. End treatment: the coiled material end needs to be sealed by using a bonding adhesive tape or polyurethane caulking paste, and after the sealed part is cured, a layer of polyurethane coating waterproof material is coated at the end.
8. Quality inspection and acceptance: the coil material book and the quality certificate retest report are complete, and the next procedure is required to be immediately carried out after the supervision acceptance is passed after the coil material book and the quality certificate are qualified by self-inspection.
In conclusion, according to the additional layer structure for the internal corner of the waterproof coiled material, the hard arc-shaped plate (adhered by 801 glue) adhered to the internal corner part replaces the traditional round corner or 45-degree splayed foot, the combination effect of the internal corner part and the waterproof coiled material can be effectively improved through the medium, and the problem of hollowing quality of the coiled material is solved.
