Description

A prefabricated, modular building system

technical field

The invention belongs to the technical field of construction, and relates to a structure characterized by movable, detachable or foldable parts, in particular to a novel assembled and modular building system.

Background technique

At present, my country's construction market still uses a large number of traditional crafts. The common shortcomings of traditional crafts are: in the production process, the production of raw materials causes huge and irreversible damage to the ecological environment and energy. For example, clay bricks cause huge damage to land resources. destruction, the country has gradually banned production. During the construction process, raw materials are wasted too much on site, construction waste pollutes the environment, construction dust pollutes the air, and construction noise affects the lives of residents. The construction period is long and the building consumes a lot of energy. Moreover, the effective area of the house is small, and the materials cannot be reused after completion, and a large amount of construction waste will be generated after relocation. In addition, the construction cost is high. With the development of the economy and the rise of labor costs, the construction cost is rising at a rate of 10% every year.

In view of the shortcomings of the above existing building structures, the state has issued a series of policies to encourage the modern construction industry. In order to achieve the purpose of "building houses in factories" and "building houses like cars", a plan is proposed: the industrialization of modern buildings is a traditional The major transformation of the development mode and path of the construction industry is based on the prefabricated production of components and prefabricated construction as the production mode, characterized by standardization of design, componentization of components, and mechanization of construction, focusing on leading industries and products, and integrating design and production , Construction and other entire industrial chains, optimize the combination of various production factors, implement regional layout, specialized production, large-scale construction, serialized processing, socialized services, and modernized business management and industrial organization forms. Its essence is the process of carrying out technological transformation on the traditional construction industry and promoting the technological progress of the construction industry.

From a global perspective, many countries are developing construction industrialization, especially the industrialization rate of housing is relatively high. For example, the industrialization rate of housing in Japan and the United States has reached 70%, the UK has reached more than 75%, and Sweden has even reached more than 80%. . The construction industrialization in France started earlier. From the 1950s to the 1970s, it was the "first generation of construction industrialization", marked by the cast-in-place process of fully assembled slabs and tool formwork; after the 1970s, it transitioned to the "second generation" "Building industrialization" is characterized by common structural parts and equipment. Unlike Europe's large-scale prefabrication and assembly route, the United States does not mention "construction industrialization", but their construction industry is still developing along the road of construction industrialization, and has reached a high level, and it pays a lot of attention to individualization, diversification. Due to the different specific conditions of each country, there are two trends in the implementation of construction industrialization: one is that France, Japan, the former Soviet Union, Sweden, Finland and many other countries are trying to realize the method of building buildings with standardized components, that is, universal Systematic principles; another trend is the reduction of stereotyped units to better unify standardization and diversification. At present, my country's construction volume accounts for about 50% of the world's total construction volume, but the construction industrialization rate is only 7%.

Therefore, in recent years, along with my country's encouragement and support for the modern construction industry, new modern construction products and new construction techniques have sprung up one after another in response to energy conservation, environmental protection, speed, safety, etc. in the new modern construction industry.

The current development of the new modern construction industry in my country is generally divided into two modes of development: 1. On the building envelope. In essence, it still continues the construction technology of traditional buildings, and selects new building materials as building envelope structures, such as: fly ash blocks, foamed cement masonry structures, and lattice hollow lightweight blocks (patent number 201120514927.9) , EPS foam concrete grouting exterior wall (patent number 201220189578.2), etc. This is a change that continues the traditional construction technology of "changing the soup without changing the medicine" and "treating the symptoms but not the root cause". It is just that some products that are more in line with the national requirements for energy saving, emission reduction and environmental protection are selected in the building materials. Therefore, its disadvantages: the degree of change is not enough, and the disadvantages have not been completely improved; but the advantages: the promotion resistance is small, and it is easier to apply to the construction industry.

2. A new type of building structure and a new type of building envelope using new technology. That is to use a variety of prefabricated concrete components to build houses like "building blocks". This is also the ideal building model most encouraged by the country. The building system of the present invention belongs to the second type, a product and construction technology of a new building structure utilizing a new technology and a new building envelope. For the invention of this building system, the development route of the domestic modern construction industry is nothing more than two kinds of panel structures: one is the panel structure without skeleton, such as: lightweight partition wall panels, prestressed concrete exterior wall panels and other products, for example, the market A unitized assembled concrete exterior wall system with a relatively high market share (patent application number 201210268026.5). The other is a skeleton plate structure, in which the skeleton form is divided into concrete skeleton form and steel skeleton form.

Among them, the disadvantages of the frameless slab structure: plate thickness, high cost, and large slab area (usually each slab covers the door and window openings, and in the case of transport, the length is the column distance, and the width is the height of the floor). The assembly process has high requirements on the crane, and the difficulty of transportation increases due to the influence of the route and the height limit. The reason is that the frameless slab relies on the overall slab and internal steel bars as the force-bearing system, and the force is transmitted to the beam-column structure through the steel bar. Excessive deflection of existing concrete materials will lead to cracking. Its span is large and its area is large. If the rigidity is low, the deflection will be large, so the requirements for slab thickness and concrete strength are relatively high. In addition, the forming process requires a formwork system made of flat molds and side molds. It is formed by pouring and vibrating processes. The formwork can only be removed after the curing strength can support the formwork removal. The production process is complicated; Heavy, heavy cranes are needed to assist in production and installation. However, the existing buildings all have aesthetic requirements, and the pursuit of individuality leads to large individual differences, so almost all formwork cannot be reused, and the cost of mold opening accounts for 30% of the total cost in the cost of the skeleton-free slab project. , major equipment investment accounts for 10% of the total cost, and can only produce different board types according to different building forms, and cannot achieve standardized production and continuous operation. Therefore, although it can be produced in a factory, the labor cost of the production process is reduced, the installation period is short, and the labor cost and equipment cost of the installation process are low; but it is still unable to make up for the cost of mold opening and fixed-value production investment interest costs; It is higher than the traditional process, and although the installation period is short, but including the production period, its total construction period has no advantage compared with the traditional process period, so the market recognition is also poor.

The disadvantages of the concrete skeleton system in the skeleton system are very similar to those of the frameless system, although the advantage is that the problem of excessive board width is solved by splitting, which is convenient for transportation, low cost, and fire-resistant. However, it still takes a long time and high cost to process formwork when encountering customized products; the difficulty of formwork processing for concrete skeleton system slabs is due to the skeleton ribs, which is more difficult to process and modify than the formwork system without skeleton slabs. The skeleton slab can also be molded. The concrete skeleton slab can hardly be molded, but can only be reprocessed. If it is not used in future production, it will cause huge waste. Moreover, a major disadvantage was exposed during the application process, that is, the anchorage length and strength of the steel bars at the connection part did not meet the requirements, which was not conducive to long-term use and earthquake resistance. For example, the relatively common prefabricated frame lightweight large wall panels in China (patent application number 201220261699.3).

After many years of research, experimentation and market analysis, the applicant has developed a steel skeleton panel. The patent name is: a thermal insulation wall panel with a frame structure, and the patent number is: 201220342163.4. Between the two long sides of the rectangular frame body, several supporting columns are vertically arranged, and a net is arranged in the frame surrounded by the rectangular frame body and the supporting columns; one side of the rectangular frame body and the supporting columns on the same side There is a spacer, the outer side of the spacer is a steel plate, the steel plate is connected to the wall exterior panel through bolts, and the other side of the rectangular frame is connected to the wall interior panel through bolts; the net is connected to the wall exterior panel Insulation material is filled between the interior panel and the wall interior panel, and a sealing strip is arranged on the side of the rectangular frame. The steel skeleton plate is welded by section steel to form a steel frame as a skeleton, so that the poured thermal insulation material is used as a core material to work together with the skeleton through the steel mesh. The skeleton and the steel column or concrete column can be connected through angle steel and bolts to achieve a safe connection between the wall panel and the column.

However, this patented product has been put into use by the applicant in a large number, and in practice it is found that there are still the following shortcomings and improvements are made: 1. The structure is complex, especially the structure of the anti-"cold bridge" part is too complicated, which is not suitable for large-scale production in factories. In the actual application process, after the product is installed, the seams are prone to cracking due to thermal expansion and contraction. 2. There is no in-depth study on the welding form of the steel skeleton, so that the welding fastness of the steel skeleton is not enough, especially after the thin-walled steel is used for a long time, especially after being corroded to a certain degree, the welded part may appear, and the material strength There is a phenomenon of weakening, and there is even the risk of cracking, which will have an extremely adverse impact on the safety of the enclosure structure. 3. Insufficient consideration of installation, not too much involved in the installation method and installation process. It is very similar to the shortcomings of steel frame thermal insulation light panels (patent number: 201320101194.5) and frame structure thermal insulation wall panels (201220342163.4).

The present invention aims at the above problems, makes up for the shortcomings of the 201220342163.4 patented product and other existing technologies, and conducts modeling research on the application process of the entire building system, and conducts experiments to provide a new type of prefabricated and modular building System; the system has the characteristics of energy saving and environmental protection, saving raw materials, fast construction period, low building energy consumption, good seismic performance, good sound insulation effect, large effective area of the house, multiple turnover and low cost.

To achieve the above object of the present invention, the present invention adopts the following technical solutions.

The invention includes a wall panel system, a roof panel system, a grid panel system, and a floor panel system.

The above-mentioned systems all include steel skeleton basic boards. The steel skeleton basic boards are rectangular frames. There are support columns parallel to each other, and a net corresponding to the area is also arranged in the heat preservation board; steel plates are arranged at the intersections of the four corners on one side of the rectangular frame and the heat preservation board.

Further, suspension rings may be respectively provided on the two long sides of the rectangular frame body. The suspension rings are connected to the rectangular frame by threads, and two suspension rings can be provided on each long side of the rectangular frame, which are respectively located at the first and third support columns; before installation, the suspension rings can be screwed on, and after installation, The lifting ring can be unscrewed.

In order to achieve a better fire prevention and heat preservation effect, as a preferred scheme of the steel skeleton basic board, the heat preservation board adopts a weight ratio of: 10%~30% EPS polystyrene particles or perlite, 30%~ 50% Portland cement, and 30%~40% fly ash.

As one of the main components of the steel skeleton basic plate structure, the rectangular frame body can be made of cold-formed thin-walled C-shaped steel, channel steel or cold-formed Thin-walled square steel pipes, and the support column can be angle steel or cold-formed thin-walled square steel pipes.

In order to securely arrange the steel plates at the joints between the four corners of the rectangular frame and the heat preservation board, a connecting steel plate perpendicular to the steel plate can be arranged in the heat preservation plate, one side of the connecting steel plate corresponds to one side of the support column, and The connecting steel plate and the support column are fixed by welding, and the joints between the steel plate and the four corners of the rectangular frame and the insulation board are also fixed by welding.

Specifically, the length of the rectangular frame is 6000~9000mm, the width is 900~1800mm, and the thickness is 100~300mm. If the rectangular frame is cold-formed thin-walled C-shaped steel, its size is: C80~C300, and the thickness is 2.5 ~3mm; if the rectangular frame is (hot-rolled ordinary) channel steel, its size is: [ 8~ [ 25; if the rectangular frame is cold-formed thin-walled square steel pipe, its size is: □80~□250, thickness 2.5~ 3mm. If the support column is angle steel, its size is: ∠30~∠50, and the thickness is 3~5mm; if the support column is cold-formed thin-walled square steel pipe, its size is: □30~□50, and the thickness is 3~5mm. The thickness of the steel plate is 10~20mm, and the length and width are 90~250mm.

In addition, the thickness of the rectangular frame exposed on the side of the insulation board without the steel plate is 20-50mm; the purpose is to prevent indoor condensation caused by the "cold bridge" effect of the exposed steel plate.

The present invention has the beneficial effects of conventional products and techniques in the prior art.

(1) Energy saving and environmental protection: the pouring insulation material of the steel skeleton basic plate in the building system of the present invention uses a large amount of fly ash and waste EPS polystyrene particles, which can play a positive role in the country's treatment of industrial waste. When the steel skeleton basic board is installed on the construction site as a prefabricated component, no dust, noise, or construction waste will be generated; therefore, the construction process of this building system is very environmentally friendly. Moreover, the thermal insulation performance of the building system is far superior to that of the existing block structure, and has a prominent effect on building energy saving, and the manufacturing process does not require heat treatment, and the production process is also very energy-saving.

(2) Saving raw materials: The basic steel frame panels in the building system of the present invention can be produced according to the design requirements and produced in a factory, so no matter from the production process or the installation process, there is basically no waste of raw materials, and the utilization rate of raw materials is almost 100%. .

(3) Fast construction period: Since the building system of the present invention adopts a prefabricated structure, wall panels are taken as an example: they are connected with building columns by angle steel and bolts, which can save a lot of labor. For example: a 10m ² wall panel is hoisted by a crane to install in place, it takes no more than 10 minutes, and only 4 to 8 sets of bolts need to be screwed, so the construction process is extremely simple and convenient; the traditional masonry method The 10 m ² wall requires a big worker and a small worker for a day to complete; while other prefabricated panel systems cannot break through the technology of bolted connection assembly at present, and can only be completed by welding.

(4) Low building energy consumption: Since the core material of the steel frame basic board in the building system of the present invention is a thermal insulation board, the thermal insulation effect is equivalent to 8 times that of the traditional 370 red brick wall, and the cooling and heating costs of the house will be reduced several times above.

(5) Good anti-seismic performance: The wall panel system of the building system of the present invention is a lightweight material, its weight is only 1/10 of the traditional wall, and because it is connected with the frame structure system, the anti-seismic performance will be obviously superior to the traditional structure.

(6) Good sound insulation effect: Since the core material (insulation board) of the wall panel system is made of comprehensive lightweight materials, its internal structure is fluffy, which is not conducive to sound transmission. Under the premise of the same thickness, the noise reduction ability is 45db greater than that of the traditional structure.

(7) The effective area of the house is large: In the case of better thermal insulation effect than the traditional brick wall, it can also greatly reduce the thickness of the wall board, thereby increasing the effective use area of the building.

(8) Can be reused many times: Traditional buildings cannot be relocated, but can only be demolished, which will generate a lot of construction waste. The building system of the present invention adopts prefabricated bolt connection, so the wall boards can be turned over. In case of relocation, the materials can be numbered after being dismantled, rebuilt in different places, and can also be recycled by the manufacturer. It can be used in conjunction with upcoming projects, and only needs to be simple on the surface. After treatment, no difference can be seen after spraying paint. For buildings connected with steel structure frames, the material reuse rate can be close to 70%, and the residual value of the building will increase by more than 10 times compared with the existing traditional structure.

(9) The construction cost is lower: the steel skeleton basic plate in the building system of the present invention is produced by factory assembly line, the product material is light, and the process is simple, so the material cost is low; The labor cost is greatly reduced, so that the final comprehensive cost of the building is at least double that of the traditional brick masonry structure.

Advantages of the present invention compared with other existing prefabricated panel systems.

(1) The present invention has the unique feature of "modularization", which can achieve "one board" universal, that is, the "basic board" can be combined with external components to meet the needs of different parts of wall panels, roof panels, floor panels, and grid panels. Function usage. This can meet the needs of industrial development to the greatest extent, and the factory can liberate production capacity to the greatest extent, without being unable to accurately locate problems due to the diversity of needs.

(2) The original "wall panel installation system" of the present invention is installed by bolts, freeing the crane to the greatest extent. Compared with other prefabricated panel systems, the speed is faster and the installation is easier.

(3) Compared with other prefabricated panels, due to the "modular" feature of the present invention, the "basic panels" can be manufactured in a factory and then assembled on site to become building demand panels, which will greatly solve the transportation problem. Especially for grid panels and wall panels, some other prefabricated grid panels, usually because the distance between the grid design nodes is basically ≥3000mm, so the grid panels should also be ≥3000mm square, which will cause problems during transportation. Bringing super-wide or super-height restrictions to the vehicle, it is necessary to use special large-scale models and go through related procedures; because the wall height is mostly around 3000mm, it will also cause the same difficulties during transportation. Even if the transportation can be satisfied, there are disadvantages such as reduced transportation volume and increased freight costs due to the particularity. The solution of the invention can save freight to the greatest extent, expand transportation capacity, and is not limited by vehicles and road conditions.

The above table is the conclusion drawn by the applicant after repeated calculations. Because of the factory production and industrial assembly installation, the present invention has much fewer procedures and much less labor than brick masonry, so the construction period will be greatly accelerated. The site of the masonry wall project includes masonry, mortar mixing, erection of scaffolding, removal of scaffolding, vertical transportation of materials and secondary transportation, indoor and outdoor plastering and other projects. The cost is also bound to be high. This comparison index refers to the comparison carried out under the condition of completing the same project progress.

The above table is the conclusion drawn by the applicant after many calculations. Because of factory production and industrial assembly installation, the present invention has much fewer procedures and much less labor than brick masonry, so the construction period will be greatly accelerated. Concrete roof (floor) surface projects include concrete vibration, steel bar binding, carpentry formwork, scaffolding erection, scaffolding removal and other projects on site. The process is complicated and the amount of labor is large, so the construction management fee and temporary construction cost are bound to be large. There are many operations, pollution to the environment, and long construction period. This comparison index refers to the comparison carried out under the condition of completing the same project progress.

The physical performance testing results of the building system basic board of the present invention are as follows.

detailed description

Example 1: Steel skeleton basic panels in the building system of the present invention.

As shown in FIG. 1 , it is a schematic structural view of the steel skeleton basic board in the building system of the present invention. In the figure, the outer frame of the basic plate of the entire steel skeleton is formed by a rectangular frame body 1, and the heat preservation board 3 is embedded in the rectangular frame body 1, and the upper and lower two long sides of the support rectangular frame body 1 are also arranged in the heat preservation board 3 . The support column 2. Four corners of the rectangular frame body 1 are respectively provided with drilled, square small steel plates 5, and the steel plates 5 are welded with nuts on the side contacted with the insulation board 3, and the bolts can be tightened by drilling when used for installation. And the suspension ring 7 is set on the long side direction of the steel skeleton basic plate, and the suspension ring 7 is a suspension ring 7 with threads; before installation, it can be screwed on, and after installation, it can be unscrewed.

As shown in Figure 2, it is the A-A sectional view of Figure 1; it can be seen from the figure that the rectangular frame body 1 in the illustrated embodiment is cold-formed thin-walled C-shaped steel, and the support column 2 is an angle steel. One side of the insulation board 3, whose thickness is slightly more than the edge of the cold-formed thin-walled C-shaped steel, is used as a side combined with the outer wall surface of the wall; The side of the adjacent interior finish. As can be seen from Fig. 2, the net 4 is placed in the insulation board 3, preferably in the middle of the insulation board 3, and is arranged in parallel with the inside and outside sides of the insulation board 3, and the size corresponds to the area of the insulation board 3, Net 4 can adopt metal net 4. It can also be seen from Fig. 2 that the parts where the drilled, square steel plate 5 overlaps with the rectangular frame body 1 are also welded together, and the other side of the steel plate 5 is vertically fixed with the first connecting steel plate 6, the first connecting steel plate 6 One side of the connecting steel plate 6 is fixed with the angle steel side of the support column 2 by welding. The role of the first connecting steel plate 6 of the basic plate is that its welding form connects the steel plate 5 and the support column 2. If the support column 2 is located in the center of the rectangular frame body 1 and adopts cold-formed thin-walled C-shaped steel, it can be welded and connected to the steel plate 5. Then the first connecting steel plate 6 can be eliminated, and directly welded.

As shown in FIG. 3 , it is an enlarged view of the corner nodes in FIG. 1 . In this illustrated embodiment, the tops of the short side rectangular frame body 1 and the support column 2 are welded with the second connecting steel plate 8; then, the second connecting steel plate 8 is welded with the inner mouth of the C-shaped steel of the rectangular frame body 1, and One end of the cold-formed thin-walled C-shaped steel of the rectangular frame body 1 is welded and sealed with a sealing plate 10; finally, as shown in Figure 2, the drilled, square steel plate 5 is connected to the rectangular frame body 1, the support column 2, and the first connecting steel plate 6 welding.

As shown in Figures 4 and 5, it is an enlarged and cross-sectional view of the corner joints when the material of the rectangular frame is channel steel. When the material of the rectangular frame 1 constituting the basic plate is channel steel, the second connecting steel plate 8 and the sealing can be cancelled. Plate 10; as shown in Figures 4 and 5, the rectangular frame is directly welded and connected, and the rectangular frame is directly welded to the support column; when the material of the rectangular frame 1 is channel steel, the remaining materials are the same as those shown in Figure 1 and Figure 2 . Because when the material of the rectangular frame body 1 is channel steel, the wall thickness of the channel steel can meet the direct welding connection, which is much larger than the wall thickness of the cold-formed thin-walled C-shaped steel. The basic plate when the material of the rectangular frame body 1 is channel steel, it is mainly used when the height of the building is more than 24m (the wall part), because when the rectangular frame body 1 is made of channel steel, the wall thickness of the channel steel is much larger than that of cold steel. The wall thickness of the curved thin-walled C-shaped steel, after anti-corrosion treatment, can withstand various harsh environments, and the service life can be the same as that of the building, which is more beneficial to the safety of use; for example: the existing high-rise In the exterior wall decoration of buildings and super high-rise buildings, whether it is glass curtain wall, dry-hanging marble, etc., the skeleton structure uses channel steel and angle steel as the keel, but the cost is also about 1/3 higher than that of cold-formed thin-walled C-shaped steel. . Therefore, the building system of the present invention takes this point into consideration, and uses different materials to form the steel skeleton basic board according to the height of the building.

Embodiment 2: Modular assembly and combination form of steel skeleton basic boards.

The modular basic board can be selected according to the development of the industry, such as: (length×width×thickness) 5980×1480×110mm, 5980×1180×120mm, 2980×1480×110mm, 2980×880×120mm, etc. As a standard panel for modular production, the basic panel type of the modular steel skeleton is the most commonly used panel type based on years of market operation data (because when installing, it is considered that there is a gap of 20-30mm between the panels) The installation margin gap, so the installation margin gap should be considered in the manufacturing process of the steel skeleton basic plate). For example: Assuming that the column distance of the building is 6000mm, when the standard plate of 5980×1480×110mm can be selected for installation, the standard plate of 5980×1480×110mm can be directly selected for installation; After assembly and combination of ×110mm and 2980×1480×110mm, it is processed into a steel frame mounting plate that meets the requirements (8980×1480×110mm) for installation.

As shown in Fig. 6 and Fig. 7, two or more steel frame basic plates are selected, and the rectangular frame body 1 of the steel frame basic plate is connected by welding to form a steel frame installation plate that meets the requirements of the building. Between the rectangular frames 1 of the steel frame basic boards, the thickness of the steel plate 11 can be adjusted (that is, the two basic boards) so as to meet the external dimensions, thus completing the assembly and combination of the steel skeleton basic boards, and also completing the steel skeleton After the basic board is modularized in the factory, it can be assembled and combined according to the needs of the building; it can complete the assembly and combination of the standard boards of the steel skeleton basic board to form a steel skeleton installation board, and can also complete the standard board and steel skeleton of the steel skeleton basic board. The assembled non-standard boards become steel skeleton installation boards. All the steel frame installation panels introduced below can be assembled and combined by steel frame basic panels to form steel frame installation panels; they can also be steel frame basic panel specifications and sizes that can directly meet the needs of buildings without assembly and combination, but they are collectively referred to as steel frame panels. Skeleton mounting plate.

Embodiment 3: The wall installation node of the steel skeleton installation board.

Regardless of whether it is directly made into a steel frame mounting plate that meets the requirements of the building, or a steel frame mounting plate assembled from steel frame basic plates through assembly and combination, the first step in the application of the wall is to first combine the steel frame mounting plate with the building. Columns (including steel columns and concrete columns) are connected, which is the first step for the steel skeleton plate to complete the wall surface assembly; it is also a major technological breakthrough for the assembly of the building system of the present invention for the existing building technology , covering a number of technical solutions such as connection with building columns, joints, anti-"cold bridge" treatment, and exterior wall finishing treatment.

As shown in Figure 8, it is a schematic diagram of the steel frame mounting plate and the steel column installation corbel of the present invention, the steel column mounting corbel is a connecting piece for the steel frame mounting plate and the steel column installation, and is used to support the steel frame mounting plate . In the figure, the support rib 13 is welded vertically to the horizontal platform steel plate 12, and then the welded piece that is welded vertically to the support rib 13 and the platform steel plate 12 is welded vertically to the steel column 14 to form a steel column installation corbel.

As shown in Figure 9, it is a schematic diagram of the steel frame mounting plate and the concrete column installation corbel of the present invention, the concrete column mounting corbel is a connecting piece for the installation of the steel frame mounting plate and the concrete column, and is used to support the steel frame mounting plate . In the figure, the support rib 13 and the horizontal platform steel plate 12 are welded vertically to each other, and then the welded part of the support rib 13 and the horizontal platform steel plate 12 is welded vertically to the concrete composed of the embedded steel plate 15 and the concrete column 16. The column corbels are embedded in parts to form a concrete column to install the corbels.

The above steel column installation corbels and concrete column installation corbels are both part of the building column, and are accessories that provide conditions for the installation of the steel skeleton installation board. The steel skeleton installation board is different from the steel and concrete columns. The necessary connectors for the installation of architectural columns, because they belong to different types of architectural columns, are collectively referred to as architectural column installation corbels.

As shown in Figure 10, it is the embodiment that the steel skeleton mounting plate of the present invention is connected with building column; Among the figure, steel column 14 or concrete column 16 are fixedly provided with some building column installation corbels from top to bottom, horizontal The cap steel plate 12 that is set is used to place the steel plate 5 and the angle code 17 that connect it with the basic plate of the steel skeleton mounting plate, and then the angle code 17 is fixed with the steel plate 5 and the cap steel plate 12 with bolts. There is a gap between the upper and lower steel frame mounting plates, the gap distance is 20-30mm, and the foamed polyethylene rod 23 is built in the gap, and two sections of steel bars 19 are respectively arranged on the inner side of the foamed polyethylene rod 23, and the steel bars 19 are welded on the rectangular Around the outside of the frame body 1, the steel bar 19 is used to fix the position of the foamed polyethylene rod 23, and there is an extruded board 25 (thickness 19mm, height 100-150mm) between the rectangular frame body 1 and the outer wall of the two steel frame mounting plates , the sealant 24 is filled between the extruded board 25 and the foamed polyethylene rod 23, and the joint of the outer wall is composed of a cement-based composite anti-seepage coating 21 from the outside to the inside (the cement-based composite anti-seepage coating is based on 90% Portland cement, 3% aluminum stearate, 2% sodium silicate, 5% calcium hydroxide, materials with waterproof and anti-seepage performance) and glass fiber mesh cement mortar composite layer 22 (glass The composite layer of fiber mesh cement mortar is composed of cement glass fiber fireproof cloth and cement (material with waterproof and impermeable properties), extruded board 25, sealant 24, foamed polyethylene rod 23, and steel bar 19.

After the wall panels are installed, different construction techniques are adopted according to the requirements of different building facades. For example: when the facade of the external wall is painted, the cement-based composite anti-seepage coating 21 and the glass fiber mesh cement mortar composite layer 22 can be applied to the external wall as a whole for overall leveling, and then the paint can be applied; the external wall is made of ceramic tiles Or in the case of marble, the next process can be directly carried out after the wall installation is completed and the joint treatment is completed.

As shown in Figure 10, it is an embodiment of the hanger corner code 17 and the supporting corner code 18 that are connected to the steel frame mounting plate of the present invention and the building column: in the figure, the hanging part corner code 17, the supporting corner code 18 and the self Fixedly set the cap steel plates 12 installed horizontally on several building columns to install the corbels from top to bottom, and connect them with bolts; because there will be construction errors no matter during the construction process of the concrete column 16 or the installation and construction process of the steel column 14 ; Therefore, the connecting hole of the hanging piece corner code 17, the supporting corner code 18 and the horizontal setting of the building column installation corbel 12 utilizes the bolt connection to make an oblong hole with the length of the plate or the direction of the building column distance. (The diameter of the hole is 21.5mm, and the length of the hole is 30mm), so as to meet the construction error of the building column, and the construction brought about remains unchanged. Corner code 17 of the hanger can open round holes in the direction of the board width or building height, but the number of openings should take into account the different load weights on the wall and the ground. If the exterior wall is painted, the load on the wall and the ground is light. Open a round hole (the diameter of the hole is 21.5mm); if the external wall is tiled or hung with marble, the load on the wall vertically to the ground will be relatively heavy, and it may be necessary to open two or more holes through calculation; It can also be welded to meet the purpose of being able to resist the weight load after the corner code 17 of the hanger is connected with the drilled and square steel plate 5 by bolts. Moreover, the number of openings in the steel plate 5 corresponding to the corner of the steel frame mounting plate and the corner code 17 of the hanger should be consistent, and the drilling positions should be consistent to ensure installation.

Supporting corner code 18 needs to open oblong holes in the direction of slab width or building height; because, if supporting corner code 18 does not have oblong holes in the direction of slab width or building height, then hanging piece corner code 17, supporting corner code The distance between 18 is the same as the distance between the two horizontally arranged steel plates 12 of the building column to install the corbel. During the installation process of the high-altitude hanging plate of the crane, the steel skeleton mounting plate is in a floating state, which cannot allow the crane to Part corner code 17 and supporting corner code 18 enter between the two horizontally set platform steel plates 12 on which the building column is installed; therefore, in order to solve this installation and construction problem, the supporting corner code 18 should Open the oblong hole in the height direction, first use the oblong hole to leave a margin of 10~30mm in the distance between the plate width or the height of the building, and wait for the steel frame installation plate and the two horizontally arranged cap steel plates 12 of the building column to install the corbel to pass through After the hanger angle code 17 and the support angle code 18 are installed in place and tightly connected, the natural bolt will be in the reasonable position of the oblong hole that the support angle code 18 opened. A major technological breakthrough in the installation of prefabricated components of this technology is a key point for the breakthrough of the assembly system of the building system of the present invention.

Embodiment 4: Description of the wall stress system of the steel frame mounting plate and necessary nodes.

In the building system of the present invention, there is another technical breakthrough, that is, whether it is the installation of the steel skeleton basic board, or the steel skeleton installation board assembled and combined by the steel skeleton basic board, under the condition of meeting the size requirements of the building envelope , it can be connected and installed with building columns. The steel frame mounting plate itself does not consider the situation indicators such as wind load resistance and thermal insulation performance, and is borne by the stress system on the rear side of the steel frame mounting plate. The building system of the present invention provides two schemes for enhancing the force bearing system. In the following introduction, In order to distinguish the two connection methods of the reinforced bearing system, it is divided into the reinforced connection form of the plate and the reinforced connection form of the whole wall. This technology solves the characteristics that the load-bearing area will be different due to the different column spacing and span of the building, resulting in different component sizes in each part, so as to resist the force load under different conditions; such as: column spacing and If the span is large, it will be greatly affected by the load; if the building is tall, the wind load at the high place will be greater than that at the low place; the wind load will be different in different regions, there are typhoons in the south, but there are few in the north; some buildings are like markets, warehouses, etc. In the case of unsuitable conditions, impact and extrusion loads are prone to occur, but ordinary factory buildings and residential buildings will not occur. Therefore, the feature of the present invention is just very outstanding, only needs to adjust individually in the area that may occur, and at the same time make individual adjustments on the inside of the building, without considering individual reasons, and the overall waste of materials is caused, The overall shape and aesthetic design of the building are not changed, and the use requirements in various situations can also be met. At the same time, it makes up for the factors such as the difference in resistance to wind loads of the steel frame installation plates assembled by the modularized factory-produced steel frame basic plates. For example: Markets and warehouses may be more considered, compared with ordinary factory buildings and residential buildings, the material of the stress system is larger; if the wind load above 30 floors is large, the material of the stress system is larger, and the wind load below 6 floors is small. Then the stress system material is smaller. In this way, since the steel frame mounting plate has uniform specifications and does not need to be too thick, the storage space can be greatly saved; more quantities can be transported during transportation, thereby reducing transportation costs. The reinforced stress system can be transported to the site after the steel frame mounting plate is connected and installed with the building columns, and then the reinforced stress system can be constructed so that it can meet the requirements of the building. In terms of material use, due to the treatment form of the position of the plate seam, two large steels are required to meet the force requirements of the wall surface such as wind load and impact load under normal conditions, and two small steels and one large steel are used together. It is used to resist wind load, impact load and other wall force requirements, so that it can save materials to a certain extent, especially when the length of the board exceeds 6000mm, the material saving is obvious; especially when the whole board composed of multiple boards Material savings are even more pronounced when the walls are joined together.

As shown in Fig. 11 and Fig. 12, it is an embodiment of the reinforced connection form of the steel frame mounting plate wall surface stress system of the present invention. In Fig. 11, it is the situation of the steel skeleton installation board, which is installed in place from the visual angle of the outside of the building. In Fig. 12, it is the situation of the steel skeleton installation plate, which is installed in place from the visual angle of the building inside. The reinforced purlins include horizontal reinforced purlins 26 and vertical reinforced purlins 27; wherein, the horizontal reinforced purlins 26 are used to weld with the fourth connecting steel plate 29 between all plates, and the fourth connecting steel plate 29 is welded with the rectangular frame body 1, and the fourth connecting The distance between the steel plates 29 is preferably between 500-1500 mm, so that the transverse reinforcing purlins 26 can become the reinforced force-bearing members of the rectangular frame body 1 . Moreover, it is necessary to consider adjusting the position of the transverse reinforcing purlin 26 and the opening direction of the groove. The transverse reinforcing purlin 26 at the position of the door and window should be in the same plane position and the same opening direction as the rectangular frame body 1 at the opening of the door and window, so as not to affect the opening direction of the door. , window installation; the transverse reinforcement purlin 26 is consistent with the length direction of the rectangular frame body 1 along the length direction of the rectangular frame body 1, but the total reduction distance in the length direction of the rectangular frame body 1 compared at both ends should not be greater than 500mm (that is, the transverse reinforcement Each side of the purlin 26 should not be greater than 250mm from the rectangular frame body 1). The vertical reinforcing purlin 27 is cold-formed thin-walled C-shaped steel, cold-formed thin-walled steel square pipe and other materials that are less than or equal to the cross-section of the horizontal reinforcing purlin 26, and is welded with the horizontal reinforcing purlin 26, and can be connected with the rectangular frame 1 at the door or window opening. Welding along the height direction of the door and window openings, or no welding is required; but if the door and window openings are of high height and are composed of two or more steel skeleton mounting plates, the horizontal reinforcing purlins 26 and vertical It is used in conjunction with the reinforced purlin 27, and it is necessary to consider adjusting the position of the vertical reinforced purlin 27 and the opening direction of the groove. The vertical reinforced purlin 27 at the door and window position should be in the same plane position as the rectangular frame body 1 at the door and window opening. The same opening direction will not affect the installation of doors and windows. The support rod 28 has no direct connection relationship with the steel skeleton mounting plate, that is, there is no direct connection relationship with the rectangular frame body 1. The function of the support rod 28 is to stabilize the lateral reinforcement purlin 26 when the length direction of the lateral reinforcement purlin 26 is greater than 3000 mm. Even when the lengthwise distance of the transverse reinforcement purlin 26 is greater, one or more support rods 28 need to be added, and the two ends of the support rod 28 are welded to the transverse reinforcement purlin 26 . Welding support rods 28 should be considered at both ends of the transverse reinforcement purlin 26. The same function of the support rod 28 is to stabilize the lateral reinforcement purlin 26. The support rod 28 does not need to be connected with the rectangular frame 1 of the steel frame mounting plate.

As shown in Fig. 13 and Fig. 14, it is an embodiment of the reinforced connection form of the whole wall of the steel skeleton mounting plate wall stress system of the present invention. In Fig. 13, it is the situation of the steel skeleton installation plate, which is installed in place from the visual angle of the outside of the building. In Fig. 14, it is the situation of the steel skeleton installation board, after being installed in place, from the visual angle of the inside of the building. Wherein, the top of the wall panel and the bottom of the wall panel are welded with the connecting steel plate 29 by using the transverse reinforcement purlin 26, the fourth connecting steel plate 29 is welded with the rectangular frame body 1, and the distance between the fourth connecting steel plate 29 is preferably between 500-1500mm. This enables the transverse reinforcement purlin 26 to become a reinforced force-bearing member of the rectangular frame body 1 . And, according to the situation, choose whether to increase the horizontal reinforcement purlin 26 between the two horizontal reinforcement purlins 26; after adding the horizontal reinforcement purlin 26, the distance between the two horizontal reinforcement purlins 26 is preferably 3000-4500mm. Among them, the vertical reinforcement purlin 27 is between two horizontal reinforcement purlins 26, the two ends of the vertical reinforcement purlin 27 are welded with the horizontal reinforcement purlin 26, and the vertical reinforcement purlin 27 is connected with the rectangular frame body 1 of the steel skeleton installation plate by the fourth connection. Steel plate 29 is welded. Welding support rods 28 should be considered at both ends of the transverse reinforcement purlins 26. The function of the support rods 28 is to stabilize the transverse reinforcement purlins 26. The support rods 28 do not need to be connected with the rectangular frame body 1 of the steel skeleton mounting plate.

Embodiment 5: Other necessary nodes on the wall surface of the steel skeleton installation board.

After Examples 1-4, the modular production of the steel skeleton basic board factory is completed, the modular steel skeleton basic board is assembled and combined into a steel skeleton installation board, and the wall is completed by prefabricated installation on site, and then the stress system is strengthened to make The wall envelope can meet a basic operation process required by the building. But this is not all of the wall engineering. There are still many positions and situations that need to be dealt with. Here, some of the most frequently occurring node forms in engineering are described to meet the architectural requirements.

As shown in Figure 15, it is an embodiment of the building system of the present invention under the condition of heat preservation. Wherein, the operation process of the steel skeleton installation plate is the same as that introduced in Embodiment 3. The assembly of the wall bearing system of the steel frame mounting plate is the same as that introduced in Implementation 4. In this figure, what needs to be added is that for the situation where the building has thermal insulation requirements, on the inside of the interior panel 30 (including: gypsum board, calcium silicate board, etc.) and the steel frame installation board, vertical Lay the inner insulation board 31 between the reinforcement purlin 27 and the lateral reinforcement purlin 26 according to the insulation requirements (the insulation board material adopts a weight ratio of: 10%~30% EPS polystyrene particles or perlite, 30%~50% silicon Salt cement, and 30%~40% of fly ash), the inner insulation board 31 is close to the inside of the steel frame mounting plate, and can be directly pasted with the steel frame mounting plate; finally, paint the inside of the interior panel 30 Can.

As shown in Figures 16 and 17, it is an embodiment of the present invention combined with a window. It can be seen from the figure that, in case 4, the description of the wall stress system of the steel frame mounting plate and the necessary nodes introduce the reinforcement purlin, which is the same as the introduction process in case 4. A plastic-steel window 32 is arranged between the rectangular frame bodies 1 of the two steel frame mounting plates, and the rectangular frame body 1 wraps the outer wall surface, and the upper, lower, left and right outer wall surfaces of the plastic-steel window 32 are connected with the two rectangular frame body 1 Use sealant 24 to fill the gap between the window and the rectangular frame body 1, and extruded plastic boards 25 are also arranged between the outdoor and indoor walls and the rectangular frame body 1, and the extruded plastic boards 25 are laid. Finally, utilize the fiberglass net cement mortar composite layer 22 and the cement-based composite anti-seepage coating 21 to brush and level, and waterproof grooves or olecranons are set on the window upper side, and slope finding is carried out at the window lower side; The bottom, left and right parts and the rectangular frame body 1 are fixed by nails 33 . After all window projects are completed, use glass glue 23 to seal the joints between the upper, lower, left and right parts of the window and the cement-based composite anti-seepage coating 21. It can be seen from Fig. 17 that the difference from Fig. 16 is that the interior is not decorated, and most of them are used in industrial buildings such as factories and warehouses, and the interior surface paint can be directly painted.

As shown in Figures 18 and 19, it is the application of the present invention in the external corner of the exterior wall panel. In Fig. 18, the steel column 14 adopts the steel column 14 that is H-shaped in section, that is, the parallel steel columns 14 on both sides, and the connecting steel columns 14 therebetween; ~30mm gap, built-in foamed polyethylene rod 23 in the gap, the inner side of the foamed polyethylene rod 23 is connected to the steel bar 19 on the outer side of the rectangular frame body 1, and an extruded board is arranged on the outer side where the two steel frame mounting plates are vertically connected 25. The sealant 24 is filled between the extruded board 25 and the foamed polyethylene rod 23, and the outer wall is composed of an outer decorative surface layer 20, a cement-based composite anti-seepage coating 21 and a glass fiber mesh cement mortar composite layer from the outside to the inside. 22 composition. Among the figure, the horizontal rectangular frame body 1 is connected with the fixed building column mounting bracket below the steel column 14, and the vertical rectangular frame body 1 is connected with the fixed building column installation bracket on the right side of the connecting steel column 14. As can be seen from Fig. 19, the difference with Fig. 18 is that the corner building column structure is a concrete structure, and the building column installation corbel and the embedded parts of the concrete building column 16 can be welded, and the rest are in the same form as Fig. 18 . If there is a need for thermal insulation, conduct thermal insulation construction as shown in Figure 15.

As shown in Figures 20 and 21, it is the application of the present invention in the inner corner of the exterior wall panel. The difference from the embodiment shown in Figures 18 and 19 is that: the extruded board 25 is arranged at the inner corners of two mutually perpendicular rectangular frames 1, and the connection between the H-shaped steel column 14 and the two rectangular frames 1 is through a channel steel cantilever 34 to realize; the channel steel cantilever beam 34 on the top of the H-shaped steel column 14 is parallel to the vertical rectangular frame body 1, and is connected by the installation of the building column corbel, and the channel steel cantilever on the upper right side of the connecting steel column 14 of the H-shaped steel The beam 34 is parallel to the horizontally upward rectangular frame body 1, and is connected through a building column installation corbel. As can be seen from Fig. 21, the difference with Fig. 20 is that the corner building column structure is a concrete structure, and the channel steel cantilever 34 and the embedded parts of the concrete column 16 can be welded, and the rest are in the same form as Fig. 20. If there is a need for thermal insulation, conduct thermal insulation construction as shown in Figure 15.

Another feature of the modularization of the steel skeleton basic boards of the building system of the present invention is that it can not only be produced and installed as a modular model of the wall panel system; Production and installation. That is to say, the steel skeleton basic board can be used in wall system, roof system, floor system and grid roof system in one board. The contribution of the present invention not only successfully develops the prefabricated steel skeleton basic board, but also deeply develops the function and scope of application of the prefabricated steel skeleton basic board. Because the scope of application is wider, the process and intensity of industrialization must be greater. The following introduces one by one the application of basic panels to roof systems, floor systems, and grid roof panel systems.

Implementation 6: Roof installation forms Ⅰ, Ⅱ and nodes of steel frame installation boards.

The roof installation form I of the steel frame mounting plate, according to the description of Example 2, whether it is directly made into a steel frame mounting plate that meets the building requirements, or a steel frame mounting plate assembled from steel frame basic plates through assembly and combination, It can be used not only on the wall, but also on the roof. This embodiment describes in detail how the steel frame mounting plate is used on the roof and the specific method of using it on the roof.

First, complete the material production process of the steel frame mounting plate according to the building requirements. Then, the rectangular frame 1 in the steel skeleton installation plate is welded with the reinforcing purlin through connecting steel plates. The role of the steel frame installation plate is to complete the roof enclosure and bear the surface load. The reinforced purlin is a component selected after calculation according to the requirements of the length of the plate. The roof load mainly solves the deflection problem of the steel frame mounting plate after being stressed, and is a bending-resistant component.

After the steel frame mounting plate, reinforced purlins, and connecting steel plates are welded and connected on the ground, they are hoisted to a reasonable position on the roof and welded to the roof beams. If the roof beams are steel beams, they can be directly welded, and if the roof beams are concrete beams, the embedded parts can be pre-embedded during the concrete pouring process, and then welded to the embedded parts.

Finally, if the roof has insulation requirements, you can choose EPS polystyrene board, extruded board, perlite and other insulation materials to lay on the roof according to the insulation requirements, and then perform roof waterproofing; if there is no insulation requirement, you can do it after the roof joint treatment is completed , directly to the roof waterproofing.

The building system of the present invention is also another major technological breakthrough for the prefabricated type for the existing building technology, covering several technical solutions such as the connection of the basic plate and the load-bearing structural beam of the building roof, seams and roof treatment.

The only difference between the roof installation form II of the steel frame installation plate and the roof installation form I of the steel frame installation plate is: in the roof installation form I of the steel frame installation plate, the steel frame installation plate and the roof installation form I After the reinforced purlins are connected on the ground first, they are hoisted to a reasonable position on the roof, so reinforced purlins are required on both sides of the steel frame mounting plate; in the roof installation form II of the steel frame mounting plate, the steel frame mounting plate is hoisted to a reasonable position position, and then at the position of the plate seam, the reinforcing purlin is used to connect the steel plate and weld with the frame of the steel frame mounting plate at the same time, and there is no difference in other forms.

The advantage of the roof installation type II of the steel frame mounting plate is to save steel, but after the steel frame mounting plate is hoisted in place, a certain degree of support is required, and the support is removed after the reinforced purlins are welded in place; the same steel frame installation The advantage of panel roof installation form I is that it saves time and effort.

As shown in FIG. 22 , it is a structural schematic diagram of the first connection method for connecting the steel frame mounting plate and the roof load-bearing structure beam from the visual angle of the upper side of the building roof. As shown in FIG. 23 , it is a structural schematic view from the visual angle of the underside of the building roof for the first connection method of the steel frame mounting plate and the roof load-bearing structural beam of the present invention. In the figure, the fourth connecting steel plate 29 is first welded to the steel frame mounting plate (the spacing is preferably between 500-1500 mm), and then the transverse reinforcing purlin 26 is welded on the connecting steel plate 29, so that the transverse reinforcing purlin 26 can become a rectangular frame body 1.
