Description

Technical Field

[0001] The invention belongs to the technical field of construction, and in particular relates to a modular system for steel structure buildings. Background Art

[0002] Steel structure modular buildings are gaining more and more attention and popularity due to their use of recyclable materials, reduction of on-site construction waste, and improvement of energy efficiency, which meet the requirements of green buildings and sustainable development. However, there are still key issues that need to be solved in steel structure modular buildings:

[0003] First, the problem of module size mismatch: In the current design and construction of steel structure buildings, due to the lack of unified modular standards, the sizes of steel structure modules and enclosure modules are not coordinated, which not only increases the adjustment workload of on-site construction, but also may lead to material waste and cost increase;

[0004] Second, the degree of module standardization is low: the core of modular buildings lies in standardization and universality, but the standards for modular design in the industry have not yet been fully unified. The sizes and interface specifications of each module are different, making it difficult to achieve large-scale batch production. At the same time, the interchangeability of the modules is limited, which in turn affects the flexibility of the building floor plan.

[0005] The above problems have resulted in the overall cost of modular buildings not being reduced as expected. Although in theory modular buildings can reduce costs through large-scale production, in practice, problems such as size mismatch and low standardization lead to additional costs, including rework costs, time costs, and increased management costs during the process. Summary of the invention

The holes on the vertical surface inside the grid frame are used to embed the enclosure module, the top surface is used to install the roof module, and the intervals between the horizontal steel pipes and the vertical steel pipes are used to embed the floor module. By finely coordinating the size relationship between each module, the steel structure module is ensured as the base point, and its spacing becomes the reference multiple unit for setting the size of the components in the module, floor module and roof module, thereby systematically solving the problem of inaccurate size matching between each module.

These components are all produced and processed in the factory and transported to the site for installation, with unified module standardization and interface specifications to solve the problem of low module standardization.

[0013] As a preferred solution, the swing door assemblies include interior doors and door head walls arranged in sequence from bottom to top, and the interior doors include interior door frames and interior door leaves hinged to the interior door frames. The upper surface of the inner door frame is fixedly connected to the lower surface of the door head wall, the door head wall is parallel to the inner and outer partition wall assemblies, and the side panels of the interior doors slightly protrude from the wall surfaces of the inner and outer partition wall assemblies, which is convenient for closing the metal sandwich wall panels and decorative adhesive wall cloths.

[0044] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0045] Embodiment 1:

[0046] like Figure 1-Figure 9 As shown, a modular system of steel structure building includes a steel structure module 1, wherein the steel structure module 1 has an internal partition embedded with an enclosure module 2 and a floor module 4, and a roof module 3 is arranged on the top of the steel structure module 1. Each part of the steel structure module 1, the enclosure module 2, the roof module 3 and the floor module 4 can be prefabricated in a factory and sent to the construction site according to the drawing requirements and the required quantity.

[0047] The steel structure module 1 includes a plurality of steel structure columns 101 parallel to each other, and also includes three groups of steel structure main beams 102 spaced apart from bottom to top, and the three groups of steel structure main beams 102 each include a plurality of transverse steel pipes and longitudinal steel pipes perpendicular to each other, wherein the end faces of the transverse steel pipes and the end faces of the longitudinal steel pipes are connected to one side of the adjacent steel structure columns 101, and the spacing dimensions of the transverse steel pipes and the longitudinal steel pipes are adapted to each enclosure module 2 and the floor module 4, and can be specifically refined according to the drawings and divided into several basic sizes, such as 1m, 2m, 3m, etc.

[0048] The three sets of steel structure main beams 102 divide the steel structure building into two floors, as follows:

[0049] The functional spaces on the first floor include a dining room, living room, bedroom, public bathroom, garage, tool room, and laundry room;

[0050] The functional spaces on the second floor include a living room, a master bedroom, three secondary bedrooms, and a public bathroom;

[0051] The steel structural column 101 can penetrate the upper and lower floors, ensuring the vertical stability of the structure.

[0052] During installation, the steel structure columns 101 and the steel structure main beams 102 are cross-arranged according to strict modular rules, and together they build a grid frame that is both regular and flexibly adjustable. The holes on the vertical surfaces inside the grid frame are all used to embed the enclosure modules 2, the top surface is used to install the roof modules 3, and the intervals between the horizontal and vertical steel pipes are all used to embed the floor modules 4. The layout of the steel structure module 1 is closely related to the dimensions of each part of the enclosure module 2 and the dimensions of each part of the floor module 4, so that each building module can be easily embedded in the predetermined steel structure module 1 space.

[0053] In addition, by finely coordinating the size relationship between each module, the steel structure module 1 is ensured as the base point, and its spacing becomes the reference multiple unit for the size setting of the components in the module 2, the floor module 4 and the roof module 3, thus systematically solving the problem of inaccurate size matching between each module. It reduces the adjustment workload of on-site construction, improves the efficiency of installation, avoids the waste of on-site processing materials and the increase of costs, so as to control the rework cost, time cost and the increased management cost in the process.

[0054] See attached Figure 1 , Figure 2 and Figure 3 The floor module 4 includes a floor assembly 401 and a plurality of submerged piles 402 arranged at intervals. The floor assembly 401 includes a plurality of prefabricated panels. The prefabricated panels can be made of concrete porous floor materials or hollow glass magnesium machine panels. The upper surfaces of the prefabricated panels are provided with decorative materials, such as stone plastic flooring, ceramic tiles, rock slabs, stones, etc. The prefabricated panels are respectively embedded in the intervals of the horizontal steel pipes and the longitudinal steel pipes. The upper end faces of the submerged piles 402 are fixedly connected to the lower end faces of the steel structure columns 101 by bolts. The submerged piles 402 are pre-buried in the foundation pit. The bottom-up construction strategy not only optimizes the structural stress distribution, but also greatly promotes the smooth progress of the construction and the overall stability of the building, reflecting the intelligent integration and efficiency improvement of modular design in promoting the process of building industrialization.

[0055] Among them, porous concrete floor slabs are known for their light weight, high strength, and good sound and heat insulation performance. They are suitable for modern buildings to reduce the weight of the structure and improve the energy-saving performance of the building. Hollow glass magnesium machine-made panels usually have the characteristics of fire resistance, moisture resistance, light weight and high strength. The hollow design may further improve the sound insulation and heat insulation performance, and may also be used to meet the fire safety requirements of specific areas.

[0056] See attached Figure 4 , Figure 5 and Figure 6The components of the enclosure modules 2 are connected by physical bolts to ensure safety and firmness, and are assisted by flexible methods such as butyl rubber strips to achieve waterproof, sealed, and cushioning and shock-absorbing effects. The enclosure module 2 includes multiple internal and external partition wall components 201, multiple cloakroom partition wall components 202, multiple casement door components 203, multiple outward-opening window components 204, entrance doors 205, multiple sliding doors 206, stairs 207 and multiple railings 208. Their sizes are multiples of the spacing between the steel structure modules 1, forming unified high-standard components.

[0057] Multiple internal and external partition wall components 201, multiple cloakroom partition wall components 202, multiple swing door components 203, multiple outward-opening window components 204, entrance doors 205, multiple sliding doors 206 and stairs 207 are respectively embedded in the holes on the vertical surface inside the grid frame, and multiple railings 208 are fixed on the upper surface of a group of steel structure main beams 102 located in the middle, wherein the end faces of the two outermost railings 208 are respectively fixedly connected to one side of the adjacent steel structure columns 101. In this embodiment, the number of internal and external partition wall components 201 is 103, the number of cloakroom partition wall components 202 is 12, the number of swing door components 203 is 13, the number of window components 204 is 23, the number of entrance doors 205 is 1, the number of sliding doors 206 is 5, the number of stairs 207 is 3, and the number of railings 208 is 21. All of these components are produced and processed in the factory, transported to the site for installation, and unified module standardization and interface specifications are used to solve the problem of low module standardization.

[0058] Furthermore, the interior of the internal and external partition wall assembly 201 is provided with a steel frame, machine-made wall panels are installed on both sides, and the hollow cavity is filled with fireproof, soundproof and heat-insulating rock wool. The upper and lower parts of the partition wall are respectively arranged on the steel structure main beam 102 of the steel structure module 1, and the partition wall surface close to the outdoor wall side is provided with a metal sandwich wall panel, and the inner wall surface is provided with a decorative adhesive wall cloth. The rock wool used is a porous sound-absorbing material, and the thermal conductivity and apparent density meet the requirements of the current relevant standards and specifications, and has good thermal insulation performance, reaching the Class A non-combustible standard, ensuring excellent fireproof, soundproof and heat-insulating performance.

[0059] In addition, a steel frame is provided inside the cloakroom partition wall assembly 202, and machine-made wall panels are installed on both sides. The cavity is filled with fire-proof, sound-proof and heat-insulating rock wool. The upper and lower end faces of the cloakroom partition wall assembly 202 are respectively connected to the floor module 4, and the walls on both sides are provided with decorative adhesive wall cloth.

[0060] See attached Figure 4 and Figure 7The swing door assemblies 203 include an interior door 2031 and a door head wall 2032 which are arranged in sequence from bottom to top. The interior door 2031 includes an inner door frame and an inner door leaf hinged to the inner door frame. The upper surface of the inner door frame is fixedly connected to the lower surface of the door head wall 2032. The door head wall 2032 is parallel to the inner and outer partition wall assemblies 201, and the side panels of the interior door 2031 slightly protrude from the wall surface of the inner and outer partition wall assemblies 201, which is convenient for closing the metal sandwich wall panels and decorative adhesive-backed wall cloths. Among them, the metal sandwich wall panels are standardized products in the market, the core material is glass fiberized, and the connection between the panels is a tongue-and-groove male-female splicing method.

[0061] See attached Figure 4 and Figure 8 The outward-opening window components 204 include upper and lower end walls 2042 and an outer window sash 2041 embedded in the middle of the upper and lower end walls 2042. At a suitable position of the outer partition wall in the enclosure module 2, the upper and lower end walls 2042 are parallel to the outer partition wall surface, and the side edges of the outer window sash 2041 slightly protrude from the outer wall surface, making it convenient for users to open it outwards.

[0062] See attached Figure 1 , Figure 2 and Fig. 9 The roof module 3 includes a plurality of steel structure ridge beams 301, the lower end surfaces of the steel structure ridge beams 301 are fixedly connected to the upper end surfaces of the steel structure columns 101, and also includes two sets of mutually inclined steel structure inclined beams 302;

[0063] Among them, the upper end surfaces of one group of multiple steel structure inclined beams 302 are fixedly connected to the upper edge of one side of the steel structure ridge beam 301, and the upper end surfaces of another group of multiple steel structure inclined beams 302 are fixedly connected to the waist of the other side of the steel structure ridge beam 301. A steel structure cross beam 303 is fixed between the sides of two adjacent steel structure inclined beams 302 that are close to each other, forming a double-sloped high and low staggered frame sloping roof, which is convenient for installing tiles or glass asbestos boards.

[0064] Further, see Attachment Figure 1 , Figure 2 and Fig. 9 , a plurality of roof colored steel tiles 304 are fixed side by side on the upper surface of the two groups of steel structure inclined beams 302, at least one of which is embedded with a photovoltaic panel 305, and skylights are arranged at staggered positions, which is conducive to the use of lighting for indoor space; the double inclined roof of the roof module 3 ensures the maximum light-receiving area for the photovoltaic panels 305 installed on the roof colored steel tiles 304, and at the same time, the roof drainage system is simpler and more convenient, and it only needs to set drainage gutters at the two lowest points along the inclined roof to collect the drainage pipes.

[0065] The working principle of the present invention is as follows: when preparing materials, all modules and components are all produced and processed in the factory, transported to the site for installation, and unified module standardization and interface specifications;

[0066] During installation, the steel structure columns 101 and the steel structure main beams 102 are cross-arranged according to strict modular rules, and together they build a grid frame that is both regular and flexibly adjustable. The holes on the vertical surfaces inside the grid frame are all used to embed the enclosure modules 2, the top surface is used to install the roof modules 3, and the intervals between the horizontal and vertical steel pipes are all used to embed the floor modules 4. The layout of the steel structure module 1 is closely related to the dimensions of each part of the enclosure module 2 and the dimensions of each part of the floor module 4, so that each building module can be easily embedded in the predetermined steel structure module 1 space.

[0067] In addition, by finely coordinating the size relationship between each module, the steel structure module 1 is ensured as the base point, and its spacing becomes the reference multiple unit for the size setting of the components in the module 2, the floor module 4 and the roof module 3, thus systematically solving the problem of inaccurate size matching between each module. It reduces the adjustment workload of on-site construction, improves the efficiency of installation, avoids the waste of on-site processing materials and the increase of costs, so as to control the rework cost, time cost and the increased management cost in the process.

[0068] Embodiment 2:

[0069] like Figure 10-13 As shown, it is basically the same as the first embodiment. The same can be referred to the first embodiment. The difference is that in order to improve the firmness and convenience of embedding each module, we make further improvements to the grid framework as follows:

[0070] The holes on the vertical surface inside the grid frame are also provided with seam-filling modules 5 , and the seam-filling modules 5 are all in the shape of square rings and cover the enclosure modules 2 .

[0071] The seam-filling modules 5 all include a filling groove 501 in the shape of a square ring. Both sides of the filling groove 501 extend into two adjacent steel structure columns 101, and the other two sides extend into two steel structure main beams 102 respectively. Both of them can be stamped and formed, and finally the side seams that are closed into a steel pipe are welded using a CNC welding machine. Multiple blocking plates 502 are fixed at intervals on both sides of the filling groove 501, and polyethylene film bags 503 are inserted inside the filling groove 501. The end of the blocking plate 502 close to the polyethylene film bag 503 is integrally installed with a steel structure roll 504. The steel structure roll 504 and the blocking plate 502 are connected and welded together at the ends, and then welded one by one to the inside of the filling groove 501 using a six-axis welding robot.

[0072] The welding operation may use a high-speed 6-axis robot of the IRB260 model, which is particularly suitable for welding of large quantities of steel pipes, especially when each steel pipe requires a large number of steel structure coils 504 and blocking plates 502 to be welded and fixed.

[0073] During installation, first insert the polyethylene film bag 503 filled with adhesive into each filling groove 501. Before inserting each enclosure module 2, use the blocking plate 502 and the steel structure roll 504 to support each polyethylene film bag 503 in the air, so that the polyethylene film bag 503 is opened in a square ring shape, which is convenient for inserting each enclosure module 2 one by one. The steel structure roll 504 squeezes the polyethylene film bag 503 to partially extend out of the filling groove 501 to fit the enclosure module 2 tightly, and then the enclosure module 2 is fixed with bolts. Then, use a baking gun to spray flames at the side seams of the enclosure module 2 to burn the polyethylene film bag 503, and use the steel structure roll 504 to squeeze out the adhesive in the polyethylene film bag 503. The adhesive that flows out gathers in each filling groove 501 and sticks to the adjacent enclosure modules 2. The enclosure modules 2 can be quickly fixed, the installation efficiency is improved, and the enclosure modules 2 can be firmly fixed in one go, so as to control the rework cost, time cost and the increased management cost during the process.

[0074] Working principle: During installation, first insert the polyethylene film bags 503 filled with adhesive into each filling slot 501. Before embedding each enclosure module 2, use the blocking plate 502 and the steel structure roll 504 to support each polyethylene film bag 503 in suspension, so that the polyethylene film bag 503 opens in a square ring shape, which is convenient for inserting each enclosure module 2 one by one. The steel structure roll 504 squeezes the polyethylene film bag 503 to partially extend out of the filling slot 501 to fit tightly against the enclosure module 2.

[0075] The enclosure module 2 is then fixed with bolts, and then a baking gun is used to spray flames toward the side seams of the enclosure module 2 to burn the polyethylene film bag 503. The adhesive in the polyethylene film bag 503 is squeezed out with the steel structure roll 504. The adhesive flows out and gathers in each filling groove 501 to stick to the adjacent enclosure modules 2, so that the enclosure module 2 can be quickly fixed.

[0076] Embodiment three:

[0077] It is basically the same as Example 1 and Example 2, and the similarities can be referred to Example 1 and Example 2. The difference is that the polyethylene film bag 503 is filled with epoxy resin glue or polyurethane glue as a binder. Since epoxy resin glue is flammable, a baking gun cannot be used to spray flames in this embodiment. Generally, a stainless steel blade is used instead, which is inserted into the side seam of the enclosure module 2 to puncture the polyethylene film bag 503, let the binder flow out, and finally the fire-retardant and heat-insulating paint is painted on the outside.

[0078] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
