Description

A waterproof construction technology for the seams of toilets with prefabricated patchwork boxes

technical field

The invention relates to the technical field of prefabricated buildings, in particular to a waterproof construction process for joints in box toilets.

Background technique

Prefabricated assembled box toilet is a kind of independent toilet as an integrated steel structure modular single building, most of which are single box sunken box design structure, and all toilets (except sanitary ware) are constructed in the factory. It is transported to the assembly site and directly hoisted and combined to form, and the sanitary ware can be installed. This way can improve construction efficiency and quality, save materials and human resources, and reduce on-site pollution and noise. However, because the prefabricated assembled box toilet needs to be hoisted separately, the joints need to be hoisted before construction can be carried out. Due to problems such as displacement between boxes, cracks caused by settlement, and damage to waterproof integrity, no matter how waterproof the independent box is, if the joints are not handled well, there will be hidden dangers of water leakage in the later stage.

The existing patchwork processing methods mainly include the following types:

1. Fill pearl cotton or other flexible materials between two adjacent boxes, and apply structural glue or other sealing materials on the surface. The disadvantages of this method are: there is no supporting structure under the pearl cotton, and when the box is displaced, the gap becomes larger, and the pearl cotton falls and sinks due to its own weight, causing cracks to sink in the glued part of the surface; structural glue or other sealing materials cannot be effective Prevents moisture from penetrating inside.

2. There is no movable displacement connecting plate and elastic non-woven waterproof layer on the surface of the box. When the box is deformed, there is no variable space structure, and the force is completely on the structural adhesive. The deformation of the structural adhesive causes cracks to collapse, and the surface layer has Risk of water leakage from cracks.

Therefore, in the prior art, there is no seam patching method that can effectively solve the above problems.

Contents of the invention

The purpose of the present invention is to provide a waterproof construction process for the bathroom joints of assembled jointed cabinets to solve problems such as displacement between the cabinets, cracking caused by settlement, and damage to waterproof integrity.

The present invention is realized through the following technical solutions:

A waterproofing construction process for joints in bathrooms with prefabricated jointed cabinets, comprising the following steps:

Step 1: The edge of the frame of the steel structure box is welded with a galvanized water-retaining steel plate that is higher than the frame, and a protruding steel plate is reserved on one side of the water-retaining steel plate;

Step 2: Assemble the cabinets, leaving seams between the water-retaining steel plates of the cabinets, filling the joints of the cabinets with pearl cotton, and pressing the pearl cotton on the convex steel plates;

Step 3: Fill and apply structural glue on the pearl cotton until the structural glue is filled to the level of the water-retaining steel plate;

Step 4: Cover the inverted U-shaped folded parts at the joints, and glue the inverted U-shaped folded parts to the joints with structural adhesive to seal the water-retaining steel plate;

Step 5: Apply polymeric waterproof paint to the wall of the cabinet, and fill the joints in the inner corners with waterproof paint;

Step 6: Apply another layer of polyester non-woven cement-based polymer waterproof layer to the wall of the box;

Step 7: laying cement mortar bonding layer;

Step 8: Lay the non-slip brick veneer and dry the cement to wipe the joints.

Further: The water retaining steel plate in step 1 is 2.5 cm higher than the frame.

Further: the width of the protruding steel plate in step 1 is 1.2 cm, the width of the seam in step 2 is 2.5 cm, and the diameter of the pearl cotton used is 3 cm.

Further: the inverted U-shaped folded part in step 4 is galvanized.

Further: in the step 5, the polymeric waterproof coating applied to the wall of the box is painted at least twice, until the wall of the box is 1 meter above, and the formed polymeric waterproof coating is 2 mm thick; The waterproof paint used at the joints is the king of leak blocking.

Further: in the step 6, the polyester non-woven cement-based polymer waterproof layer is applied to a height of 20 cm on the wall of the box body.

Further: the cement mortar ratio of the cement mortar bonding layer in the step 7 is 1:3, and the thickness of the cement mortar bonding layer is 5-8 cm.

Further: the thickness of the anti-slip brick veneer is 1 cm.

Compared with the prior art, the present invention has the following advantages:

The edge of the box is welded with water-retaining steel plates, even if there is water leakage, it will not quickly spread to the next box. The convex steel plate solves the gravity shedding problem of the pearl cotton due to its own weight, and prevents the pearl cotton from falling and sinking due to its own weight, causing cracks to appear on the surface of the rubberized part;

The galvanized inverted U-shaped folding parts are used to buckle on the joints. The galvanized folding parts are movable and play a certain role in supporting the waterproof layer of polyester non-woven cement-based polymers, staggering the space between different boxes. Tensile force on the polyester non-woven cement-based polymer waterproofing layer during inconsistent settlement, preventing it from cracking.

The polyester non-woven cement-based polymer waterproof layer has a certain elastic space, which can avoid the risk of water leakage caused by fine settlement.

The invention discloses a construction technique for waterproofing seams of bathrooms with assembly-type joint-jointed boxes, which comprises the following steps:

Step 1: The edge of steel structure box frame 1 is welded with galvanized water-retaining steel plate 2 that is 2.5 cm higher than the frame, and a convex steel plate 2.1 is reserved on one side of water-retaining steel plate 2, and the width of convex steel plate 2.1 is 1.2 cm;

Step 2: Assemble the cabinet, leave a seam with a width of 2.5 cm between the water-retaining steel plates 2 of the cabinet, fill the joints of the cabinet with pearl cotton 3, and the diameter of pearl cotton 3 is 3 cm. 3 compacted on the convex steel plate 2.1;

Step 3: Fill and apply structural adhesive 4 on the pearl cotton 3 until the structural adhesive 4 is filled to the level of the water-retaining steel plate 2;

Step 4: Cover the galvanized inverted U-shaped folded part 5 at the seam, and bond the inverted U-shaped folded part 5 to the joint with structural glue, and seal the water-retaining steel plate 2;

Step 5: Apply at least two coats of polymeric waterproof paint to the height of 1 meter above the wall of the box body. The formed polymeric waterproof coating 6 is 2 mm thick, and fill the joints at the inner corners with plugging king;

Step 6: Apply another layer of polyester non-woven cement-based polymer waterproof layer 7 to a height of 20 cm on the wall of the box;
