Description

Technical Field

[0001] The utility model relates to the technical field of structural waterproofing, in particular to a structural waterproofing structure between a steel structure modular building wall and a structure. Background Art

[0002] In recent years, with the rapid development of my country's construction industrialization, people's requirements for living environments have continued to increase. Traditional construction methods can no longer meet people's needs. Modular construction, as an emerging construction technology, with its standardized design, factory prefabrication, and assembly construction, is gradually becoming the direction of future construction development. Modular construction is based on unit modules. Unit module buildings are often exposed to rain during transportation and construction. At the same time, after the building is completed, it is necessary to consider preventing water from seeping into the gaps between the module joints. Self-drainage must be achieved to prevent water from penetrating into the room and affecting residents' use. This requires that unit modular buildings must have a certain degree of independent waterproof performance to ensure the waterproof reliability of the unit modules.

[0003] The existing waterproof wall is directly fixed to the modular building, and there is a through seam between the wall and the structure. The current common practice is to use sealant to seal this seam to achieve the waterproof effect of the unit module. However, this method has high requirements for the construction process of sealing. It is often prone to leakage due to incomplete or discontinuous sealing. At the same time, the sealant is prone to aging and is limited by the service life, which also brings certain risks to the reliability of waterproofing. Utility Model Content

[0004] The purpose of the utility model is to provide a structural waterproof structure between the wall and structure of a steel structure modular building, by arranging a bottom beam, a bottom secondary beam, a top beam, a top secondary beam, and a structural column to provide support for the light steel keel partition wall, so that the light steel keel partition wall is installed on the outside of the concrete structure floor, by installing rainwater baffles and spraying sealant on the outside of the bottom beam, the bottom secondary beam, the top beam, the top secondary beam and the structural column, the water penetration path is extended, the original single material waterproofing is upgraded to double waterproofing of structure and material, and the hidden danger of water seepage in modular buildings is greatly reduced.

[0005] To achieve the above-mentioned purpose, the utility model provides a structural waterproof structure between the walls and structures of a steel structure modular building, including a concrete structure floor, a light steel keel partition wall and a bottom beam.

The top beams are arranged in two groups symmetrically front and back about the midpoint of the top secondary beam, and structural top sealing plates are installed equidistantly between the front and rear groups of top beams. The bottom beam, top beam and the outer side of the structural column are welded to rainwater baffles.

[0009] Preferably, sealant is sprayed between the light steel frame partition wall and the concrete structure floor.

[0011] Preferably, the bottom secondary beam and the top secondary beam are arranged transversely when viewed from the side.

[0012] Preferably, the inner sides of the bottom beam and the top beam are provided with reserved partition wall installation positions for the structural floor.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-7 As shown, the embodiment of the present invention provides a structural waterproof structure between the wall and the structure of a steel structure modular building, which is constructed by waterproofing the bottom, top and side of the unit modular building structure and the wall. The structure includes:

[0027] Concrete structural floor 1, light steel frame partition wall 2, bottom beam 3;

[0028] A light steel frame partition wall 2 is installed on the outside of the concrete structural floor 1, and a bottom beam 3 is installed at the bottom of the light steel frame partition wall 2. The bottom beam 3 is connected to the bottom secondary beam 7 through outer bolts, and the bottom beam 3 is connected to the structural column 20 through top bolts.

[0029] The top of the structural column 20 is bolted to a top beam 11, and the top beam 11 is connected to a top secondary beam 12 through outer bolts. Two groups of top beams 11 are symmetrically arranged about the midpoint of the top secondary beam 12, and a structural top cover plate 13 is installed equidistantly between the front and rear groups of top beams 11.

[0030] The bottom beam 3, top beam 11 and outer sides of the structural column 20 are all welded with rainwater baffles 10; the structure provides support for the light steel keel partition wall 2 by setting the bottom beam 3, bottom secondary beam 7, top beam 11, top secondary beam 12 and structural column 20, so that the light steel keel partition wall 2 is installed on the outer side of the concrete structure floor 1;

[0031] Rainwater baffles 10 are installed on the outside of the bottom beam 3, bottom secondary beam 7, top beam 11, top secondary beam 12 and structural columns 20 and sprayed with sealant 4. This structure achieves a double waterproof effect by adopting "physical waterproofing + material waterproofing";

[0032] Specifically, rubber pads 5 are installed at the joints of the bottom beam 3, bottom secondary beam 7, top beam 11, top secondary beam 12 and structural column 20; sealant 4 is sprayed between the light steel keel partition wall 2 and the concrete structural floor 1;

[0033] The material used for the rainwater baffle 10 is a stainless steel "Z"-shaped folding piece 101; the bottom secondary beam 7 and the top secondary beam 12 are arranged horizontally from the side; and the inner sides of the bottom beam 3 and the top beam 11 are both provided with a structural floor reserved partition wall installation position 6.

[0034] Through structural construction methods, a structural waterproofing is formed on the steel structure modular building, which can effectively solve the performance requirements of the module unit's self-waterproofing; by reserving recesses or adding baffles on the modular structure, a structural water retaining structure is formed between it and the wall. After the wall is installed, the connection between the wall and the structure will form a staggered connection relationship. According to the principle that water flows to lower places, even if there is clear water flowing into the unit module building, the gap between the wall and the structure will be transformed from the original through seam into a turning seam, extending the water penetration path, forming a double waterproofing of structure and material, thereby reducing the risk of manual quality requirements of workers during the construction process and achieving a reliable waterproofing effect.

[0035] When manufacturing the bottom floor slab of the modular steel structure, the concrete floor slab 1 is retreated at the wall position around the modular unit building to create a height difference between the joint between the wall and the structure and the finished surface of the floor slab. At the same time, the gap between the structure and the wall is sealed to form a double protection of structural waterproofing and material waterproofing. When rainwater flows through the gap along the wall, because the floor slab is higher than the wall installation seam, even if the construction quality of the sealant 4 is flawed, no water will penetrate into the room, thus achieving a structural waterproofing effect.

[0036] When the steel structure is modularized, a stainless steel "Z"-shaped folding piece 101 is welded on the outside of the frame top beam 11 to form a rain baffle 10. The light steel keel partition wall 2 is installed on the inner side of the rain baffle 10. The gap between the light steel keel partition wall 2 and the top beam 11 is blocked by the rain baffle 10. The gap between the rain baffles 10 is below the seam between the light steel keel partition wall 2 and the top beam 11, which effectively prevents waterproofing. The gap between the rain baffle 10 and the light steel keel partition wall 2 is glued to form a double protection of structural waterproofing and material waterproofing. When rainwater flows down, it will follow the light steel keel partition wall 2, thereby eliminating the hidden danger of water leakage.

[0037] When the steel structure is modularly manufactured, a stainless steel "Z"-shaped folding piece 101 is welded to the outside of the structural column 20 to form a rain baffle 10. The light steel frame partition wall 2 is installed on the inside of the rain baffle 10. The gap between the light steel frame partition wall 2 and the structural column 20 is blocked by the rain baffle 10, and the through seam between the light steel frame partition wall 2 and the structure is converted into a turning seam, which further extends the water penetration path. At the same time, the gap between the rain baffle 10 and the light steel frame partition wall 2 is glued to form a double protection of structural waterproofing and material waterproofing. When rainwater flows down the wall, the double protection can eliminate the hidden danger of water seepage.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
