The modular building is a novel building form of an assembly type building, also called a box building, and takes each use space as a unit, and is preprocessed through modularization in a factory, then transported to an installation site, and assembled together through a professional connection mode to form a multifunctional living space. The modular building is divided into a permanent type and a temporary type, wherein the temporary modular building is mainly a box type building or a movable box house, the combination form is flexible and changeable, and the temporary modular building can be repeatedly used at different places.
However, a plurality of box bodies of the movable box house are connected with each other, and the joints are provided with inevitable splicing seams, so that certain hidden danger of water leakage exists. In some exemplary technologies, some are to erect a pitched roof, and some are to lay a waterproof roll on the top of the box body to block external rainwater, however, the construction of these waterproof structures has certain difficulty, and the waterproof structure of the box type movable house still has the problem of water leakage after long-term use.
In order to reduce the difficulty of the construction of a waterproof structure, improve the construction efficiency and simultaneously improve the waterproof performance of a box type movable house, the invention provides a construction method of the waterproof structure of the box type movable house.
Referring to fig. 1 to 3, in an embodiment of the present invention, a method for constructing a waterproof structure of a box-type prefabricated house includes the following steps:
step S10, connecting and fixing two adjacent boxes through connecting pieces to adjust the width of a seam between the boxes to a target width;
it should be noted that, as shown in fig. 1 and fig. 2, when a plurality of cases 10 are hoisted in place, an obvious splice seam 10a is generated between an exposed corner post and an exposed corner post, between a frame beam and a frame beam, the width of the seam is generally different from 2mm to 10mm, and the depth of the seam is the height of the section of the frame beam.
In this embodiment, for convenient follow-up construction to provide whole waterproof construction's steadiness, accessible bridge sign indicating number, connecting pieces such as twist lock adjust the seam 10a width between the box 10 to target width, lead to box 10 to take place the displacement owing to reasons such as foaming volume expansion in order to avoid box 10 to glue the in-process, avoid structural deformation to cause the influence to the waterproof layer.
Step S20, embedding a first sealing rubber strip into the bottom of a joint between the box bodies;
in this embodiment, the first sealing rubber strip is embedded at the bottom of the seam 10a, so that the first sealing rubber strip has a primary waterproof performance. The first sealing rubber strip can be made of rubber, and the shape of the first sealing rubber strip can be T-shaped, so that the first sealing rubber strip can conveniently receive and support a foaming agent filled from the top of the seam 10a subsequently, and the reliability of the waterproof structure is improved.
Step S30, injecting foaming agent into the joint between the boxes;
in this embodiment, the foaming agent may be a polyurethane foam caulking agent, and the foaming agent is not limited thereto. It can be understood that the waterproof performance of the box-type movable house can be further improved by injecting foaming agents such as polyurethane foam gap fillers.
The foaming agent is mainly used for forming a foaming filling layer at the joint 10a along the length and depth direction of the joint and serving as a base layer of a waterproof layer, so that the joint can be effectively blocked and rainwater can be prevented from entering the joint.
It should be noted that the foamed filler layer should be continuous and full along the length and depth of the seam 10 a. The foaming agent is a polyurethane foaming agent which has high density, high hardness and strong bonding property and can be rapidly foamed and cured after glue discharging, the polyurethane foaming agent can be effectively bonded with the box room base metal, and can be rapidly foamed and expanded after glue discharging to prevent deformation, so that a foam filling layer with uniform foaming, compactness and pressure resistance is formed, and the construction quality and the waterproof effect of the filling layer are effectively improved.
Step S40, after the foaming agent foam is solidified, cleaning redundant foam;
in this embodiment, the curing time of the polyurethane foam caulking agent is about 1 hour, so that 1 hour is required to wait after the foaming agent is injected, and after the foam is cured, the excess foam is cleaned, so as to facilitate the embedding of the second sealing rubber strip 11.
Of course, in some other embodiments, different blowing agents may be used, and the waiting time for curing may be determined by reference to the product characteristics of the actual blowing agent, and the waiting time for curing of the blowing agent is not limited herein.
Step S50, embedding a second sealing rubber strip into the top of the joint between the box bodies;
in this embodiment, as shown in fig. 2, the second sealing rubber strip 11 may also be made of rubber, and may also be T-shaped, so that the second sealing rubber strip 11 and the box room base material can be firmly bonded by a strong back adhesive, the waterproof performance can be further improved, and the reliability of the waterproof structure can be improved.
The first sealing rubber strip and the second sealing rubber strip 11 are mainly used for secondarily plugging the joint 10a, preventing rainwater from permeating and protecting the foam filling layer. It should be noted that the T-shaped sealing rubber strips used should be made of rubber with good toughness and corrosion resistance, the phenomenon that the joints are deformed due to the change of the external temperature to cause the pulling and the cracking of the rubber strips is avoided, and meanwhile, the first sealing rubber strips and the second sealing rubber strips 11 should be firmly bonded by strong gum and the box room base metal to improve the sealing degree.
And step S60, covering the joint between the metal plate and the box body.
In this embodiment, as shown in fig. 2, the metal plate 12 should be made of an alloy material with self corrosion resistance and good durability, such as aluminum alloy or stainless steel, and the thickness of the metal plate 12 may be 0.5 to 1.5mm, but not limited thereto. In order to ensure the durability and workability of the metal plate 12, it is preferable to use a buckle plate made of an aluminum alloy having high corrosion resistance. The thickness of the metal plate 12 is not too thick, and in this embodiment, the thickness of the metal plate 12 may preferably be 0.8mm, so as to facilitate factory processing and field adjustment.
The metal plate 12 mainly has the effects of providing physical shielding at the joint 10a, reducing the aging effect of external environments such as ultraviolet rays on the foaming agent, the first sealing rubber strip and the second sealing rubber strip 11, enhancing the durability and the aging resistance of the waterproof plugging material, reducing the limitation of waterproof measures on the appearance of the box house building to the maximum extent, improving the overall appearance of the building, and providing possibility for more variable building shapes.
The invention provides a construction method of a box type prefabricated house waterproof structure, which comprises the following steps that firstly, two adjacent box bodies 10 are connected and fixed through a connecting piece, so that the width of a seam 10a between the box bodies 10 is adjusted to a target width; then embedding the first sealing rubber strip into the bottom of a joint 10a between the box bodies 10; then, injecting a foaming agent into the joint 10a between the cases 10; subsequently, after the foaming agent foam is solidified, cleaning the redundant foam; then embedding the second sealing rubber strip 11 into the top of the joint 10a between the box body 10; finally, the joint 10a between the metal plate 12 and the case 10 is covered. Among the above-mentioned technical scheme, seam 10 a's waterproof shutoff is carried out to seam 10a department between the box 10 through adopting the form of foamer, adhesive tape and metal sheet 11 to the prefabricated house, has promoted the waterproof performance of box prefabricated house, has reduced the degree of difficulty of waterproof construction simultaneously, and then has improved the efficiency of construction.

Thus, the fine gap between the waterproof structure and the box body 10 caused by dust, oil stain and the like can be avoided, and the waterproof performance and the installation stability of the waterproof structure are further influenced.
In order to further ensure that the waterproof performance of the waterproof structure of the box-type prefabricated house can meet the requirement, the step of injecting the foaming agent into the joint between the box bodies can be preceded by the following steps:
step S26, checking whether dust and oil stains exist on the surface of the joint of the box body;
step S27, when dust and oil stains exist on the surface of the joint of the box body, the outer edge of the frame beam at the joint of the box body is cleaned again;
and step S28, when dust and oil stains do not exist on the surface of the joint of the box bodies, the step of injecting the foaming agent into the joint between the box bodies is executed.
In this embodiment, before the foaming agent is injected into the joint 10a, the surface of the joint 10a may be inspected again to ensure that the surface is free from floating dust, oil, and the like.
Further, in an embodiment, before the step of injecting the foaming agent into the joint between the boxes, the method further includes:
and step S29, when the environmental humidity is lower than the target humidity value, spraying a first amount of water to the joint of the box body.
