Description

Technical Field

[0001] This invention belongs to the field of prefabricated housing technology, and more specifically, it relates to a prefabricated steel-concrete composite building and its assembly method. Background Technology

[0002] "Prefabricated house" is a common name for prefabricated housing. Its full name is prefabricated modular housing. It is a type of housing built using industrialized production methods. Some or all of the housing components are prefabricated in a factory and then transported to the construction site. The components are then assembled using reliable connection methods to build the housing. The difference with "prefabricated house" is that only some parts are prefabricated. On the construction site, it is poured like a traditional building. It is not like "building blocks" as you might imagine.

[0003] Patent document CN108005234A discloses a modular prefabricated house, including a modularly assembled main building structure, an integrated bathroom for the prefabricated house, a solar water heater, a rainwater collection system, an FRP septic tank, an integrated kitchen for the prefabricated house, a solar photovoltaic power generation system and a wind power generation system, and a wind-solar hybrid power system; the modularly assembled main building structure includes a modular building roof, a modular building floor, modular frame components, modular door and window components, and modular building wall panels; the modular building roof includes corrugated color steel plate, a roof reinforcement layer, a rock wool insulation layer, and a glass wool insulation layer, which can realize modular assembly and also achieve energy self-sufficiency.

[0004] Traditional prefabricated buildings have certain shortcomings during installation and use. Prefabricated buildings use splicing and fixing structures to fix prefabricated components to form the house structure. The overall structural strength is relatively poor, and gaps exist between multiple exterior wall panels, making seamless fixing impossible. This reduces the sealing, waterproofing, and insulation of the prefabricated building, resulting in poor performance. Secondly, traditional prefabricated buildings have poor earthquake resistance. Lacking auxiliary earthquake-resistant structures, they are prone to disintegration under external forces, reducing safety during use. Furthermore, traditional prefabricated buildings lack auxiliary drainage structures. While their structural properties allow for flexible installation in any location, the lack of a drainage system prevents proper drainage of daily water usage, reducing practicality. Summary of the Invention

[0005] The purpose of this invention is to provide a prefabricated steel-concrete composite building and its assembly method, which can solve existing problems.

[0006] The problem solved by this invention is:

[0007] 1. Prefabricated buildings use splicing and fixing structures to fix prefabricated components to form a building structure. The overall structural strength is poor, and there are gaps between multiple exterior walls, making it impossible to achieve seamless fixing. This reduces the sealing, waterproofing, and heat insulation of prefabricated buildings, resulting in poor performance.

[0008] 2. Traditional prefabricated buildings have poor earthquake resistance. Prefabricated buildings do not have auxiliary earthquake-resistant structures, making them prone to disintegration under external forces, which reduces the safety of prefabricated buildings during use.

[0009] 3. Traditional prefabricated buildings do not have auxiliary drainage structures. Due to their structural properties, prefabricated buildings can be flexibly installed and used in any location. However, the lack of drainage structures means that daily water use cannot be properly drained, reducing the practicality of prefabricated buildings.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0011] A prefabricated steel-concrete composite building includes elastic supports and a fixed base plate. The elastic supports are fixedly installed at the bottom of the fixed base plate. Several sets of first plates are spliced ​​and installed on the upper outer surface of the fixed base plate. A fixed top frame is provided at the upper end of the first plates, and several sets of second plates are spliced ​​and installed on the top outer surface of the fixed top frame. Concrete is poured inside both the first and second plates, and several sets of connecting steel pipes are inserted into the inner sides of both the first and second plates. The several sets of connecting steel pipes are arranged side by side. A storage box is fixedly installed at the lower part of the fixed base plate. A sewage pipe is provided between the fixed base plate and the storage box. Two sets of first plates or two sets of second plates arranged diagonally are fixed by connecting angle brackets.

[0012] As a further technical solution of the present invention, both the first plate and the second plate include a heat insulation board, a precast plate, and a thermal insulation board. The heat insulation board is fixedly installed on one outer surface of the precast plate, and the thermal insulation board is fixedly installed on the other outer surface of the precast plate. The interior of the precast plate is a hollow structure, and the side of the precast plate is provided with a butt groove. When splicing and fixing multiple first plates or second plates, concrete is poured into the precast plate of the first plate or second plate, so that the concrete is poured between multiple precast plates, thereby improving the integrity of the first plate or second plate after installation and improving the structural strength of the prefabricated building.

[0013] As a further technical solution of the present invention, the two sets of precast slabs are spliced ​​and fixed together by a combination clamp. The inner side of the combination clamp is provided with a through slot, and both the upper and lower ends of the combination clamp are provided with circular insertion holes. A sealing gasket is fixedly installed in the middle of the outer surface of the combination clamp. When the two sets of precast slabs are joined together, the combination clamp plays a role in connecting and fixing the two sets of precast slabs, and at the same time allows concrete to flow between the two sets of precast slabs. After the concrete solidifies, the two sets of precast slabs are seamlessly connected, which improves the airtightness of the prefabricated building. Secondly, the setting of the sealing gasket can increase the sealing effect of the combination clamp and prevent concrete leakage between the two sets of precast slabs.

[0014] As a further technical solution of the present invention, both ends of the fixed corner frame are L-shaped structures, and connecting strips are spliced ​​and installed on both sides of the fixed corner frame. Columnar clips are fixedly installed at both the upper and lower ends of the fixed corner frame. The fixed corner frame, together with the connecting strips, can fix the first plate or the second plate at opposite corners. The connecting strips and the combination clamps are all designed with a splicing structure, so that the first plate or the second plate can be arbitrarily connected during installation.

[0015] As a further technical solution of the present invention, a splicing top plate is fixedly installed on the upper end of the fixed top frame, and a support rod and a fixing strip are fixedly installed on the inner side of the fixed top frame. A lower clamping strip is fixedly installed on the bottom of the fixed top frame. Several sets of support rods are arranged side by side, and the support rods can support and fix the bottom of the splicing top plate.

[0016] As a further technical solution of the present invention, the elastic support includes an outer sleeve rod and an inner sleeve rod. The inner sleeve rod is movably sleeved on the inner side of the outer sleeve rod. The outer sleeve rod and the inner sleeve rod are elastically connected by a spring. A fixed top plate is fixedly installed on the outer surface of the top end of the inner sleeve rod. By using the spring in conjunction with the outer sleeve rod and the inner sleeve rod, the elastic support has an elastic buffer structure, which improves the seismic resistance of prefabricated buildings.

[0017] As a further technical solution of the present invention, both sides of the inner sleeve rod are fixedly installed with sliding buckles, both sides of the outer sleeve rod are provided with limiting sliding grooves for use with the sliding buckles, and an arc-shaped clip is fixedly installed at the upper middle part of the fixed top plate.

[0018] As a further technical solution of the present invention, a partition plate is fixedly installed in the middle of the inner side of the storage box, and the interior of the partition plate is a hollow structure. Two sets of pipes are fixedly installed on the side of the storage box, and a water supply pipe is fixedly installed inside the storage box. A sloping roof is fixedly installed on the upper end of the second plate. By using the storage box, domestic water can be stored, and daily drainage of prefabricated buildings can be collected, so that it has a water storage and water collection structure.

[0019] The assembly method and specific operation steps for this steel-concrete composite prefabricated building are as follows:

[0020] Step 1: Embed the elastic support and storage box underground, and use the fixed top plate and arc-shaped clips to connect and fix the bottom plate, so that the fixed bottom plate is fixed to the top of the elastic support.

[0021] Step 2: Use combination clamps to fix several sets of first plates to the upper part of the fixed base plate, and use fixed corner brackets to fix the joint of two sets of first plates. At the same time, insert connecting steel pipes between several sets of first plates and pour concrete to reinforce them.

[0022] Step 3: Hoist the fixed top frame onto the first panel, fix the spliced ​​top panel with the fixed top frame, and at the same time hoist the second panel onto the fixed top frame. Insert the connecting steel pipe and pour concrete to reinforce the second panel. Finally, hoist the sloping roof.

[0023] The beneficial effects of this invention are:

[0024] 1. By setting up first and second panels and combining clamps, the steel pipe and concrete can enhance the structural integrity of the prefabricated steel-concrete composite building during installation, providing excellent sealing, waterproofing, and insulation. By adding connecting steel pipes and pouring concrete, multiple first or second panels can be seamlessly spliced, improving the sealing effect of the exterior wall structure. During operation, multiple elastic supports are first pre-embedded and fixed, and then a fixed base plate is fixed to the upper part of the elastic supports to improve the seismic resistance of the prefabricated building. When assembling the first or second panels, the combining clamps, combined with the connecting grooves, allow assembly of the first or second panels without distinguishing their connection positions. The combining clamps adopt a splicing structure. The design allows the combination clamps to be secured between two sets of first or second panels, providing a connecting and fixing function during the installation of the first or second panels. Simultaneously, the combination clamps allow concrete to be poured into multiple precast slabs of the first or second panels. Since the interior of the precast slabs is hollow, the pouring of concrete ensures a seamless connection between the first or second panels after installation, improving the overall integrity of the installed first or second panels and enhancing the structural strength of the prefabricated building. Furthermore, the addition of connecting steel pipes reinforces the installation of the fixed top frame and fixed bottom plate, further enhancing the structural strength of the first and second panels. Utilizing the first and second panels and the combination clamps, the pouring of concrete enables seamless splicing of the prefabricated building, improving its safety and sealing.

[0025] 2. By setting up elastic supports, the bottom of the prefabricated steel-concrete composite building has a buffer protection structure during installation, which can effectively reduce the vibration of the prefabricated building and improve its stability. During operation, the outer sleeve is first buried underground, and a spring is inserted into the inner sleeve. Simultaneously, the inner sleeve is inserted into the outer sleeve, and a sliding buckle is installed at the limiting groove to form a limiting and fixing structure between the outer and inner sleeves. The arc-shaped clip of the inner sleeve is then inserted into the corresponding groove at the lower end of the fixed base plate to complete the connection of the elastic supports, preventing misalignment. Bolts are then used to fix the fixed top plate and fixed base plate, completing the overall fixing of the elastic supports. The use of springs in conjunction with the outer and inner sleeves creates an elastic buffer structure, improving the seismic resistance of the prefabricated building and preventing cracking due to vibration. By setting up elastic supports, the prefabricated steel-concrete composite building has an elastic buffer structure, improving its safety.

[0026] 3. By installing a storage tank at the bottom of the prefabricated steel-concrete composite building, a certain amount of domestic water can be stored, and domestic sewage can be stored to prevent direct discharge to the outside. Because of its prefabricated structure design, the prefabricated steel-concrete composite building can be flexibly installed in any location. However, there are certain problems with water supply and drainage in prefabricated steel-concrete composite buildings. Firstly, when the installation location does not have water supply and drainage pipes, the prefabricated building cannot operate normally. The storage tank is equipped with a partition, dividing the tank into a clean water tank and a sewage tank. Domestic sewage can be discharged into one side of the partition using a sewage pipe, while clean water located on the other side of the partition can be extracted for use via a water supply pipe and pump. This solves the daily water problem of the prefabricated building and improves its functionality. Attached Figure Description

[0036] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0037] like Figure 1-7 As shown, a prefabricated steel-concrete composite building includes an elastic support 1 and a fixed base plate 2. The elastic support 1 is fixedly installed at the bottom of the fixed base plate 2. Several sets of first plates 6 are spliced ​​and installed on the upper outer surface of the fixed base plate 2. A fixed top frame 7 is provided at the upper end of the first plates 6, and several sets of second plates 11 are spliced ​​and installed on the top outer surface of the fixed top frame 7. Concrete is poured inside both the first plates 6 and the second plates 11, and several sets of connecting steel pipes 8 are inserted into the inner side of both the first plates 6 and the second plates 11. The several sets of connecting steel pipes 8 are arranged side by side. A storage box 5 is fixedly installed at the lower part of the fixed base plate 2. A sewage pipe 3 is provided between the fixed base plate 2 and the storage box 5. Two sets of first plates 6 or two sets of second plates 11 arranged diagonally are fixed by connecting and fixing with fixed corner brackets 4.

[0038] Both the first panel 6 and the second panel 11 include a heat insulation board 12, a precast panel 13, and a thermal insulation board 15. The heat insulation board 12 is fixedly installed on one outer surface of the precast panel 13, and the thermal insulation board 15 is fixedly installed on the other outer surface of the precast panel 13. The interior of the precast panel 13 is a hollow structure, and the side of the precast panel 13 is provided with a butt groove 16. When splicing and fixing multiple first panels 6 or second panels 11, concrete is poured into the precast panel 13 of the first panel 6 or second panel 11, so that the concrete is poured between multiple precast panels 13, thereby improving the integrity of the first panel 6 or second panel 11 after installation and improving the structural strength of the precast building.

[0039] Two sets of precast slabs 13 are spliced ​​and fixed together by a combination clamp 14. The inner side of the combination clamp 14 is provided with a through slot, and both the upper and lower ends of the combination clamp 14 are provided with circular insertion holes 30. A sealing gasket 31 is fixedly installed in the middle of the outer surface of the combination clamp 14. When the two sets of precast slabs 13 are joined together, the combination clamp 14 plays a role in connecting and fixing the two sets of precast slabs 13, and at the same time allows concrete to flow between the two sets of precast slabs 13. After the concrete solidifies, the two sets of precast slabs 13 are seamlessly connected, which improves the airtightness of the prefabricated building. Secondly, the setting of the sealing gasket 31 can increase the sealing effect of the combination clamp 14 and prevent concrete leakage between the two sets of precast slabs 13.

[0040] Both ends of the fixed corner bracket 4 are L-shaped structures. Connecting clips 27 are spliced ​​and installed on both sides of the fixed corner bracket 4. Columnar clips 26 are fixedly installed at both the top and bottom ends of the fixed corner bracket 4. The fixed corner bracket 4, together with the connecting clips 27, can fix the first plate 6 or the second plate 11 at opposite corners. The connecting clips 27 and the combination clamps 14 both adopt a splicing structure design, so that the first plate 6 or the second plate 11 can be arbitrarily connected during installation.

[0041] The top of the fixed top frame 7 is fixedly installed with a splicing top plate 9, and the inner side of the fixed top frame 7 is fixedly installed with a support rod 17 and a fixing strip 19. The bottom of the fixed top frame 7 is fixedly installed with a lower clamping strip 18. Several sets of support rods 17 are arranged side by side. The support rods 17 can support and fix the bottom of the splicing top plate 9.

[0042] The elastic support 1 includes an outer sleeve rod 20 and an inner sleeve rod 23. The inner sleeve rod 23 is movably sleeved inside the outer sleeve rod 20. The outer sleeve rod 20 and the inner sleeve rod 23 are elastically connected by a spring. A fixed top plate 24 is fixedly installed on the outer surface of the top end of the inner sleeve rod 23. By using the spring in conjunction with the outer sleeve rod 20 and the inner sleeve rod 23, the elastic support 1 has an elastic buffer structure, which improves the seismic resistance of the prefabricated building.

[0043] Both sides of the inner sleeve rod 23 are fixedly installed with sliding buckles 22, and both sides of the outer sleeve rod 20 are provided with limiting grooves 21 that cooperate with the sliding buckles 22. An arc-shaped clip head 25 is fixedly installed at the upper middle part of the fixed top plate 24.

[0044] A partition plate 28 is fixedly installed in the middle of the inner side of the storage box 5, and the interior of the partition plate 28 is hollow. Two sets of pipes are fixedly installed on the side of the storage box 5, and a water supply pipe 29 is fixedly installed inside the storage box 5. A sloping roof 10 is fixedly installed on the upper end of the second plate 11. With the storage box 5, domestic water can be stored, and daily drainage of prefabricated buildings can be collected, so that it has a water storage and water collection structure.

[0045] The assembly method and specific operation steps for this steel-concrete composite prefabricated building are as follows:

[0046] Step 1: Embed the elastic support 1 and storage box 5 underground, and use the fixed top plate 24 and arc-shaped clip 25 to connect and fix the bottom plate 2, so that the fixed bottom plate 2 is fixed to the top of the elastic support 1.

[0047] Step 2: Use the combination clamp 14 to fix several sets of first plates 6 to the upper part of the fixed base plate 2, use the fixed corner bracket 4 to fix the joint of the two sets of first plates 6, and at the same time insert the connecting steel pipe 8 between the several sets of first plates 6 and pour concrete to reinforce them.

[0048] Step 3: Hoist the top frame 7 onto the first plate 6, fix the spliced ​​top plate 9 through the top frame 7, and at the same time hoist the second plate 11 onto the top frame 7. Insert the connecting steel pipe 8 and pour concrete to reinforce the second plate 11. Finally, hoist the sloping roof 10.

[0049] This type of prefabricated steel-concrete composite building, by setting up a first plate 6, a second plate 11, and a combination clamp 14, enhances the structural strength and integrity of the prefabricated building during installation. The steel pipes, combined with concrete, improve the building's sealing, waterproofing, and insulation properties. By adding connecting steel pipes 8 and pouring concrete, multiple first plates 6 or second plates 11 can be seamlessly spliced, improving the sealing effect of the exterior wall structure. During operation, multiple elastic supports 1 are first pre-embedded and fixed, and then a fixed base plate 2 is fixed to the upper part of the elastic supports 1, thereby improving the seismic resistance of the prefabricated building. During the assembly of the first plates 6 or second plates 11, the combination clamp 14, in conjunction with the connecting groove 16, allows for assembly of the first plates 6 or second plates 11 without distinguishing their connection positions. The combination clamp 14 employs a splicing mechanism. The modular design allows the combination clamp 14 to be clamped between two sets of first plates 6 or second plates 11, serving as a connection and fixation during the installation of the first plates 6 or second plates 11. Simultaneously, the combination clamp 14 allows concrete to be poured into the precast slabs 13 of multiple first plates 6 or second plates 11. The precast slabs 13 have a hollow interior; after concrete pouring, the first plates 6 or second plates 11 achieve seamless connection after installation, improving the integrity of the first plates 6 or second plates 11 and enhancing the structural strength of the prefabricated building. Furthermore, the addition of connecting steel pipes 8 reinforces the installation of the fixed top frame 7 and fixed bottom plate 2, further enhancing the structural strength of the first plates 6 and second plates 11. Utilizing the first plates 6, second plates 11, and combination clamp 14, the addition of concrete enables seamless splicing of the prefabricated building, improving its safety and sealing.

[0050] By setting up the elastic support 1, the bottom of the prefabricated steel-concrete composite building has a buffer protection structure during installation, which can effectively reduce the vibration of the prefabricated building and improve its stability. During operation, the outer sleeve 20 is first buried in the ground, and a spring is inserted into the inner side of the outer sleeve 20. At the same time, the inner sleeve 23 is inserted into the outer sleeve 20. A sliding buckle 22 is installed at the limiting groove 21, so that a limiting and fixing structure is formed between the outer sleeve 20 and the inner sleeve 23. Then, the arc-shaped clip 25 of the inner sleeve 23 is inserted into the fixed bottom. At the groove corresponding to the lower end of plate 2, the connection operation of elastic support 1 is completed to avoid misalignment during installation. Then, bolts are used to fix the top plate 24 and the bottom plate 2 to complete the overall fixing operation of elastic support 1. With the spring and the outer sleeve rod 20 and inner sleeve rod 23, elastic support 1 has an elastic buffer structure, which improves the seismic resistance of prefabricated buildings and prevents cracking of steel-concrete prefabricated buildings due to vibration. By setting elastic support 1, the steel-concrete prefabricated building has an elastic buffer structure, which improves its safety.

[0051] By installing a storage tank 5, the prefabricated steel-concrete composite building can store a certain amount of domestic water and sewage during installation and use, preventing direct discharge to the outside. Because of its prefabricated structure, the prefabricated steel-concrete composite building can be flexibly installed in any location. However, it has certain problems with water supply and drainage. Firstly, if the installation location lacks water supply and drainage pipes, the building cannot operate normally. The storage tank 5 is equipped with a partition plate 28, dividing the space into a clean water tank and a sewage tank. Sewage can be discharged into one side of the partition plate 28 within the storage tank 5 using a sewage pipe 3. Simultaneously, clean water located on the other side of the partition plate 28 can be extracted from the storage tank 5 using a water pipe 29 and a pump, thus solving the daily water problem of the prefabricated building and improving its functionality.
