Beneficial effects of the present invention:

The present invention is a new type of green prefabricated steel structure building system, which is based on the modularized "double modulus" coordination and "module combination" technology as the main feature of the building and is characterized by embedded steel structures and PC slabs. Industrialized building technology system, which runs through the whole process of building (residential) design, processing, installation, equipment installation, decoration, smart home, etc., realizes the industrialization, intensification and socialization of the whole process of building construction, thereby improving the building quality. Improve project quality and efficiency, realize energy conservation, emission reduction and resource conservation.

The main feature of the embedded assembly house of the present invention is that the building system adopts a dual-modulus coordinated forming module mechanism, which can combine the building planes and building facades of various houses ranging from 80㎡ to 160㎡. As long as the standard board formed by the basic module and some special-shaped boards are added, the plane and elevation dimensions of various living requirements can be met, thereby forming a standardized design and laying the foundation for factory production. The building adopts a steel structure load-bearing system and PC large slab series, laminated floor (roof) panels, EC wall panels, and ALC wall panels to form a complete main structure, which improves the service life and seismic performance of the building. The PC slab (external wall panel) adopts an inner insulation structure with an insulation layer in the middle of concrete on both sides, which meets the thermal insulation function and improves the energy-saving effect. At the same time, it meets the requirements of fire prevention and sound insulation. During the installation process, scaffolding, formwork, plastering and other items were basically canceled, beams, columns cast-in-place and steel bar binding and other processes were cancelled, the wet work on site was reduced, and the integrated decoration made the surface of the model flat and smooth, canceling the The traditional mortar leveling process can directly carry out puttying, whitening and other processes, saving materials. Therefore, the construction period of this prefabricated industrial building is shortened by 2/3 compared with the conventional one, and the labor cost is reduced by 2/3, which ensures safe production and engineering quality. At the same time, since the corners of the steel structure do not protrude, the usable area can be increased by 3% to 5%, and the advantages of energy saving and environmental protection are prominent. After comparative analysis of the cost of the main structure, the cost of the steel structure prefabricated house is basically the same as that of the traditional concrete structure, but its construction period is 1/3 of the traditional one, shortening the investment recovery period, and judging from the current steel market price trend, Traditional labor costs continue to increase, steel prices are falling, and the cost of steel structure housing is expected to further decrease.

The present invention adopts a steel frame or a steel frame-supporting structure as the main stress-bearing system, wherein the columns are made of rectangular steel tube concrete, and the beams are made of high-frequency welded H-shaped steel beams or hot-rolled H-shaped steel beams.

The external wall panel of the present invention selects prefabricated concrete PC board, and this wallboard adopts three-layer structure, and the outer layer and the inner layer are prefabricated concrete panels with 50 thick reinforcements, and the core layer is 150 EPS thick thermal insulation material. This kind of exterior wall panel is connected with the main structure in a mosaic way, and the whole wall of the room is embedded in the steel frame. Compared with the light-weight wallboards used in general steel structure houses, this kind of wallboards has high rigidity, good overall performance and no cracks.

The interior wall panel of the present invention adopts NALC board, which has light weight and high strength; the most important point is that it is already a finalized product, has perfect product standards and structure atlas, and realizes large-scale production.

The floor slab of the present invention is combined with prefabricated concrete laminated floor slabs and reinforced truss floor bearing slabs, and 60 thick prefabricated laminated floor slabs plus 60 mm cast-in-place layers are used on the main floors. The steel truss floor deck is used in the bathroom. Due to the same-floor drainage technology, the floor of the bathroom is lower, and the requirements for leakage are higher. Therefore, it is a creative choice to use the steel truss floor deck to deal with it.

The fireproof protection of the steel structural member of the present invention mainly adopts the double-layer protection method of combining fireproof coating and fireproof plate, first spraying fireproof coating and then hanging NALC fireproof board, the comprehensive fire resistance time is greater than 4 hours, far longer than general steel structure building fire prevention Require. In the construction process of the fireproof board, it can be fixed by self-tapping nails or pasted; the effect of the two methods can meet the fire resistance time requirement, and the advantages of the pasted method are small space occupation, high construction efficiency and low cost.

The invention has broad prospect and great market potential. At this stage, it is especially suitable for the construction of residential buildings such as affordable housing, demolition and resettlement housing, shantytown renovation housing, and various commercial housing. Significant economic, environmental and social benefits can be achieved after promotion.

All the components of the present invention are produced in a factory and installed mechanized, which reduces on-site construction workers, basically eliminates large-scale scaffolding and formwork projects, cancels beams and columns cast-in-place and reduces on-site steel bar binding and other processes, reducing on-site wetness. operation, the construction period is shortened by 1/3 compared with the conventional one, and the labor cost is reduced by 2/3, ensuring safe production and project quality.

The present invention adopts modular design and coordination, which is the most basic and important element in establishing an industrialized building system. It is the basis for the industrialization and integration of buildings and the realization of universal, interchangeable and supporting building products. It adopts "double-modulus" coordination Technical system, horizontal basic modulus: 1P=300mm, vertical basic modulus: 1P=300mm.

The present invention adopts a steel frame-support system as a stress system. When the number of floors of the building is less than 12 floors, a pure steel frame structure system can be used, that is, the frame is used as a load-bearing and lateral force-resistant structural system along the longitudinal and horizontal directions of the house. Because the frame system can provide a large internal use space, the building layout is flexible. In addition, the frame has fewer types of rods, simple structure, and short construction period. Therefore, the frame system is a widely used structural system for structures with a small number of floors. When the building has more than 12 floors and less than 30 floors, the steel frame-support structure system can be used. The frame-support structure is formed by vertically arranging supports on one or several spans of the frame, and the supporting truss part plays a role similar to shear. The effect of the force wall. Under horizontal action, the supporting members in the supporting truss part only bear the tensile and compressive axial forces. This structural form is very effective in terms of bearing capacity and deformation. Compared with the pure frame structure, this structural form greatly improves the lateral stiffness of the structure.

The main column of the present invention adopts a rectangular tubular concrete column. Rectangular pipe columns have high torsional rigidity, high bearing capacity, regular shape, light and beautiful structure, and good architectural applicability; rectangular pipe concrete columns are filled with concrete in rectangular pipes, and have good fire resistance and stability, and The structure composed of H-shaped steel uses less steel and lower cost. Compared with round steel pipes, the beam-to-column connection structure is relatively simple, does not produce space interpenetration, is easy to process, and does not require formwork during pouring. It has already been used in construction. be widely used.

The beam of the present invention adopts hot-rolled H-shaped steel and welded H-shaped steel beam. Hot-rolled steel beams are simple in structure, low in processing cost, and the cross-sectional size is limited by the specifications of the steel; welded steel beams are characterized by easy combination of cross-sectional sizes, but the processing time is long and the processing cost is high.

The invention welds the diaphragm inside the rectangular tube, pre-welds the short steel girder outside the column, welds the flange of the steel beam and the pre-welded short steel girder flange outside the column, and connects the web and the web of the pre-welded short steel girder with double splint high-strength bolts. The ductility of the joint is improved; when the column wall plate is thin, the problem of connecting the rectangular pipe column and the rigid joint of the beam is solved. Because steel is resistant to tension, compression, and shear, it can be bent relatively sharply, so it is a material with excellent ductility. When there is a strong earthquake energy, the elastic deformation of steel can be relied on to absorb the strong external force and overcome rigidity with softness. The beam-to-column joint with a short beam inner diaphragm is used, and the plastic hinge moves from the column surface to the beam at a certain distance from the column surface under the action of the earthquake, which fully protects the beam-column weld and avoids the deterioration of the connection deformation capacity leading to brittle failure. The steel frame and frame-support structure system has high energy dissipation capacity and excellent plastic performance, and the biggest advantage compared with the concrete structure is that it reduces the self-weight of the structure and reduces the adverse effects during earthquakes, such as reducing the overturning moment at the bottom of the structure , reduce the representative value of gravity load, etc. Rectangular tubular concrete columns have large plastic deformation when damaged, which improves the energy dissipation capacity of the building; the steel tubes and concrete work together, the node domain stiffness is large, and the shear bearing capacity is high, which can prevent pure steel columns from being easily damaged in large earthquakes. The disadvantage of shear failure; under strong earthquakes, it is easier to meet the seismic mechanism requirements of strong columns and weak beams.

The installation method of the PC exterior wall panel of the present invention adopts an embedded type, that is, the exterior wall panel is embedded between two columns. Compared with the commonly used external wall panels, the building facade is smooth and flat, the corners of the internal space are not abrupt, and the layout is flexible, which increases the usable area of the internal space and improves the comfort of the house. The interior wall panel (ALC panel) of the present invention has high strength and light weight, which is only 1/4 of concrete and 1/3 of clay brick; the thermal insulation performance is 10 times that of ordinary concrete, 7 times that of clay brick, and is Building material with superior thermal insulation performance; good flame retardant and fire resistance, its material is composed of silicate material, high thermal resistance coefficient, good volume thermal stability, high fire resistance, no harmful gas; Good sound absorption and sound insulation, can create a highly airtight indoor space, providing a quiet and comfortable living environment; convenient construction, standard wall panel size, light weight, can greatly reduce the input of manpower and material resources, and the panel installation process is simple and efficient , can effectively shorten the construction period.

The invention adopts the composite slab of steel bar truss, makes the steel bar in the floor slab into a steel bar truss, and connects the steel bar truss with concrete pouring to form a concrete thin plate member, and pours concrete on it after on-site installation to form an integral floor slab. The present invention creatively adopts the steel bar truss floor deck, makes the steel bars in the floor into a steel bar truss, welds the steel bar truss and the profiled galvanized steel plate into an integral floor member, and pours concrete on it to form an integral floor. It has: 1. The overall performance of the floor is good, which is conducive to earthquake resistance; 2. It is convenient for the layout of pipelines; 3. It reduces the workload of tying steel bars on site by about 70%, shortening the construction period; 4. It greatly reduces the amount of formwork and scaffolding on site; 5. More Two floors can be constructed at the same time; 6. The steel bars are evenly arranged to improve the construction quality.

The fire protection design of the present invention fully considers the characteristics of poor corrosion resistance, heat resistance and fire resistance of steel materials, so the anticorrosion and fire prevention of building decoration and steel components are considered uniformly, and the anticorrosion and fire prevention performance of steel components are enhanced by the air tightness wrapped by fireproof boards , to meet the fire code requirements. The method is as follows: first spray anti-rust paint on the surface of the steel member, then spray fire-resistant paint, and then wrap the fire-proof board.

If the development of reinforced concrete structure makes construction from manual to mechanized, then the application of steel structure will modernize residential construction, and steel structure residential will become an important symbol of the modernization of architecture. "Steel structure is an environmentally friendly residence, and steel structure conforms to the concept of sustainable development." In the 21st century, steel structure will occupy a vast construction market. Under the background of promoting the industrialization of housing in our country, the steel structure system will become the mainstream of the housing structure system.
