Because of its multiple advantages such as high efficiency, environmental protection and sustainable utilization, it has broad development prospect and application value in the existing market.

[0003] The existing monomer box house exists after splicing wall, waste material and cost. INVENTION CONTENTS

[0004] The utility model discloses a kind of assembly type concrete box houses, by setting the wall of vacancy, the splicing surface of box house after splicing is single-layer wall, reduce material consumption.

[0005] The utility model mainly realizes the purpose through the following technical solutions:

[0006] A kind of assembly type concrete box house, including several monomer box houses, several The monomer box house is sequentially spliced in longitudinal direction, and longitudinal direction between two The monomer box house of adjacent is equipped with longitudinal connecting piece, the longitudinal connecting piece can position the relative connecting position of two The monomer box house of longitudinal adjacent;

[0007] The monomer box house includes wall and top plate, the longitudinal connecting piece is connected between the wall and the top plate, the wall is equipped with vacancy on one side, and the longitudinal connecting piece of one side of the vacancy can be connected with outer tooling.

[0008] The monomer box house is set to have no bottom surface and sets the wall of one side as vacancy, to reduce the weight of monomer box house, reduce hoisting pressure, so that longitudinal connecting piece is less likely to be damaged, guarantee the service life of longitudinal connecting piece.

[0009] Outer tooling is: connecting piece connecting the edge of wall of one side of vacancy when monomer box house is hoisted. It is used to connect the monomer box house with vacancy as a whole, to prevent excessive deformation of monomer box house due to the setting of vacancy during hoisting.

[0010] The monomer box house is only provided with wallboard and top plate, without bottom surface, after longitudinal connection of several monomer box houses, the top plate of monomer box house located below can be used as the bottom surface of upper unit box house at the same time, to a certain extent, reduce dead weight and material use, save cost. Because the setting of bottom surface is reduced, the cost of installation and manufacturing can be saved accordingly.

[0011] After the single box houses are longitudinally assembled, the single box house at the bottom bears a large force, because the single box house is not provided with a bottom plate, can take the whole ground as a bottom surface, has a large supporting area, can reduce the concentrated stress in the vertical direction, and reduces the risk of increasing structural damage.

[0012] The wall body is provided with a hollow surface on one side, which can improve the applicability of the single box house, and a plurality of single box houses can be horizontally spliced to form a plurality of different house structures.

[0013] When the single box houses are longitudinally assembled, the longitudinal connecting piece is positioned to connect the opposite positions of the upper and lower single box houses, so that the longitudinal axes of the two are coincident, the vertical interlayer connection of the box body is enhanced, the integrity is improved, the interlayer horizontal force is resisted, the load of the longitudinal connecting piece is increased due to the misaligned connection of the upper and lower single box houses, and the longitudinal connecting piece is damaged.

[0014] Because the wall body has a hollow surface, the overall structure of the single box house is unstable during hoisting, the connecting node bears a large load, and is easily damaged. The longitudinal connecting piece provides a connecting point for the external tooling, and during hoisting, the external tooling is horizontally pulled together to increase the redundancy of the structure, so that the structure can maintain its integrity and stability when encountering unexpected loads such as strong earthquakes, strong winds, impacts, explosions, etc., and provide a backup load transfer path, thereby effectively resisting continuous collapse.

[0015] Further, the wall body includes a concrete frame and a plurality of wall panels, the plurality of wall panels are embedded in the side surface of the concrete frame, and the hollow surface and the plurality of wall panels are circumferentially enclosed along the side surface of the concrete frame.

[0016] The concrete frame includes a frame beam and a frame column, and the longitudinal connecting piece is used to connect the frame column of the upper single box house and the frame beam of the lower single box house.

[0017] Because the wall body of the single box house is provided with a hollow surface on one side, the overall structure is poor in stability after a plurality of single box houses are longitudinally connected, and the side of the hollow surface is prone to deformation. In order to make the overall structure more stable, the wall body of the utility model is provided with a concrete frame for support, so as to improve the stability and bearing capacity of the overall structure. Because the concrete frame itself has good strength and rigidity, and in the longitudinally connected single box house, the concrete frame can share and transfer the load, so as to prevent the overall instability caused by insecure connection.

[0018] The wall panel is located in the middle of the concrete frame, so that the concrete frame and the wall panel form a whole, which can effectively disperse and transfer the load, avoid stress concentration, improve the stability and bearing capacity of the overall structure, and at the same time, can enhance the seismic performance of the structure, and ensure the safety of the building under extreme conditions.

[0019] Specifically, the concrete frame comprises a frame beam of concrete, a frame column of concrete and a concrete slab. The concrete frame serves as the main load-bearing structure of the box house and has high strength and good stability. The longitudinal connecting member is connected to the concrete frame, thereby ensuring the stability and safety of the entire box house structure.

[0020] Further, the longitudinal connecting member comprises a longitudinal connecting member A, which comprises a pre-buried bolt A and a vertical pipe, the vertical pipe is inserted into the top of the frame beam, the pre-buried bolt A is located in the frame column and passes through the top plate and into the vertical pipe, and the pre-buried bolt A is fixedly connected with the vertical pipe.

[0021] Through the fixed connection of the pre-buried bolt A and the vertical pipe, the frame column of the upper single box house is firmly connected with the frame beam of the lower single box house, thereby enhancing the overall integrity and stability of the structure. The vertical pipe is used as a connecting medium, which is convenient for construction and adjustment. Meanwhile, the pre-buried bolt A is connected and accommodated by the vertical pipe, and the vertical pipe is arranged in the frame beam of the lower single box house, without damaging the surface structure of the box house, and the holding force among the longitudinal connecting member A, the frame column of the upper single box house, the top plate of the lower single box house and the frame beam of the lower single box house is better, thereby enhancing the structural stability of the connecting point.

[0022] Further, the longitudinal connecting member comprises a longitudinal connecting member B, which is located at a position close to the bottom on one side of the vacancy surface.

[0023] The longitudinal connecting member B comprises an L-shaped connecting member and a plurality of pre-buried connecting bolts, the L-shaped connecting member is provided with two mutually perpendicular plates, one of the plates is tightly attached to the top plate, and the other plate is tightly attached to the frame column, the plurality of pre-buried connecting bolts pass through one of the plates and the top plate and are inserted into the frame beam of the lower single box house, and the remaining pre-buried connecting bolts pass through the other plate and are inserted into the frame column.

[0024] Each of the pre-buried connecting bolts is fixedly connected with the frame beam or the frame column.

[0025] After a plurality of box houses are longitudinally stacked and connected, the connecting node needs to bear the weight from the upper box house and the load in two horizontal directions, and the connecting member is easily damaged due to too much pressure. The L-shaped connecting member is used to connect the concrete frame and the top plate / ground in the utility model, the L-shaped connecting member is provided with two mutually perpendicular plates, and the pre-buried connecting bolts pass through the plates of the L-shaped connecting member, thereby dispersing the original stress concentrated on the pre-buried connecting bolts to the plates of the L-shaped connecting member, and reducing the risk of damage of the structure due to stress concentration.

[0026] Furthermore, a partition is provided in the middle of the L-shaped connector, and the partition is a right-angled triangle plate. The two right-angled sides of the right-angled triangle plate are respectively fixed on the center lines of the two right-angled surfaces of the L-shaped connector. The L-shaped connector is also provided with two triangular panels parallel to the partition, and the two triangular panels are connected on both sides of the L-shaped connector.

[0027] Because the L-shaped connector is a longitudinal connector and bears horizontal and longitudinal loads, when subjected to external loads, the connection part is repeatedly pulled, the L-shaped connector may deform, and the two flat plates may not fit tightly against the concrete frame and the top plate surface. In order to enhance the structural stability of the L-shaped connector, the present invention provides three right-angled triangular steel plates in the middle and at both ends of the L-shaped connector, so that the two right-angled sides of the right-angled triangular steel plates are respectively connected to the two flat plates of the L-shaped connector. The provision of the three right-angled triangular steel plates can disperse the stress transmitted to the two flat plates of the L-shaped connector over a larger area, reducing the situation of single-point stress, thereby reducing the risk of deformation and damage, thereby extending the service life of the L-shaped connector and reducing fatigue damage caused by repeated loads.

[0028] Furthermore, the wall panel is a filled sandwich wall.

[0029] To further reduce the pressure on the vertically connected individual container houses and ensure safe installation, this utility model employs infill sandwich walls, typically made of lightweight materials such as lightweight concrete, foam plastic, or other composite materials. These materials have a low density, resulting in a lighter overall wall panel weight. This helps reduce the overall weight of the vertically connected container houses, reducing the pressure on lifting equipment and foundations. Furthermore, the sandwich walls' excellent thermal insulation properties can also mitigate the effects of temperature fluctuations on the material.

[0030] Furthermore, steel bars are laid in the concrete frame, and the steel bars extend along the concrete frame and span the side surfaces of the infill sandwich wall, with both ends of the steel bars bent toward the infill sandwich wall.

[0031] By wrapping the concrete frame around the exterior of the infill sandwich wall, the ends of the steel bars within the concrete frame can extend across the sides of the infill sandwich wall and bend toward it. The concrete frame outside the infill sandwich wall is interconnected by the internal steel bars to form a complete structure, enhancing the overall strength and stability of the wall and preventing it from buckling and deforming during installation. The ends of the steel bars are tilted toward the infill sandwich wall, which facilitates a tight connection between the steel bars and the wall, improving shear and tensile resistance and ensuring the safety and durability of the structure.

[0032] Due to the bending of the steel bars, multi-edge reinforcement can be carried out, and force in one direction can be transmitted to another direction and dispersed to the whole wall, so that the destruction of the wall structure caused by excessive load or stress concentration can be avoided, and the risk of damage at the steel bar connecting point can be reduced to a certain extent.

[0033] Further, the surface of the joint of the two adjacent single box houses is provided with a rectangular caulking groove, and the caulking grooves of the two adjacent single box houses completely cover the joint of the two adjacent single box houses.

[0034] In order to reduce the risk of leakage of the joint of the two adjacent single box houses, a rectangular caulking groove is arranged on the surface of the joint. After installation, caulking, edge sticking and other sealing treatments are carried out on the joint of the two single box houses through the caulking groove to prevent cracking and leakage in the later period. The caulking groove completely covers the joint of the two adjacent single box houses, facilitating smooth and rapid sealing operation of the joint in the later period.

[0035] In summary, the utility model has the following beneficial effects compared with the prior art:

[0036] 1. The utility model can connect the upper and lower box bodies into a whole through the longitudinal connecting pieces, enhance the vertical interlayer connection of the box body, improve the integrity, resist the interlayer horizontal force, and the longitudinal connecting pieces on one side of the hollow surface can connect the external tooling, temporarily pull together on one side of the hollow surface, and the integrity and stability of the single box house are enhanced during hoisting, and the longitudinal connection of the utility model is mechanical connection, which is convenient for quick disassembly and assembly and can improve the disassembly and assembly efficiency.

[0050] The single box house comprises a wall 2 and a top plate 1, and the longitudinal connecting piece is connected between the wall 2 and the top plate 1.

[0051] One side of the wall 2 is provided with an empty face 202, and the longitudinal connecting piece on one side of the empty face 202 can be connected with external tooling.

[0052] The external tooling is a connecting piece connecting the edge of the wall 2 on one side of the empty face 202 when the single box house is hoisted, which is used to connect the single box houses with the empty face 202 into a whole, so as to prevent the single box house from being excessively deformed due to the setting of the empty face 202 during hoisting.

[0053] One side of the wall 2 is provided with an empty face 202, which can improve the applicability of the single box house, and a plurality of single box houses can be horizontally spliced to form a plurality of different house structures.

[0054] The monomer box room is provided with no bottom surface and one side wall 2 is provided with a vacancy 202, so as to reduce the weight of the monomer box room, reduce the hoisting pressure, make the longitudinal connecting piece less likely to be damaged, and ensure the service life of the longitudinal connecting piece.

[0055] The monomer box room is provided with no bottom surface and one side wall 2 is provided with a vacancy 202, so as to reduce the weight of the monomer box room, reduce the hoisting pressure, make the longitudinal connecting piece less likely to be damaged, and ensure the service life of the longitudinal connecting piece.

[0056] The monomer box room is provided with no bottom surface and one side wall 2 is provided with a vacancy 202, so as to reduce the weight of the monomer box room, reduce the hoisting pressure, make the longitudinal connecting piece less likely to be damaged, and ensure the service life of the longitudinal connecting piece.

[0057] The monomer box room is provided with no bottom surface and one side wall 2 is provided with a vacancy 202, so as to reduce the weight of the monomer box room, reduce the hoisting pressure, make the longitudinal connecting piece less likely to be damaged, and ensure the service life of the longitudinal connecting piece.

[0058] The monomer box room is provided with no bottom surface and one side wall 2 is provided with a vacancy 202, so as to reduce the weight of the monomer box room, reduce the hoisting pressure, make the longitudinal connecting piece less likely to be damaged, and ensure the service life of the longitudinal connecting piece.

[0059] The monomer box room is provided with no bottom surface and one side wall 2 is provided with a vacancy 202, so as to reduce the weight of the monomer box room, reduce the hoisting pressure, make the longitudinal connecting piece less likely to be damaged, and ensure the service life of the longitudinal connecting piece.

[0060] As an implementable manner of the above scheme, the external tooling is an I-shaped steel, and the I-shaped steel is located at one side of the vacancy, and two ends of the I-shaped steel are connected to two different wall bodies respectively.

[0061] Further, the wall body 2 comprises a concrete frame 203 and a plurality of wall plates, the plurality of wall plates are embedded in the side surface of the concrete frame 203, and the vacancy 202 and the plurality of wall plates are circumferentially surrounded along the side surface of the concrete frame 203.

[0062] The concrete frame 203 comprises frame beams and frame columns, and the longitudinal connecting piece is used for connecting the frame column of the upper single box house and the frame beam of the lower single box house.

[0063] The overall structure is less stable due to the vacancy surface 202 arranged on one side of the single box house wall 2, and the vacancy surface 202 is prone to deformation. In order to make the overall structure more stable, the concrete frame 203 is arranged in the wall 2 to provide support, and the wallboard is embedded in the plane enclosed by the concrete frame 203. The concrete frame 203 improves the stability and load-bearing capacity of the overall structure. Since the concrete frame 203 itself has good strength and rigidity, and in the longitudinally connected single box house, the concrete frame 203 can share and transfer the load, preventing the overall instability caused by insecure connection.

[0064] The wallboard is located in the middle of the concrete frame 203, so that the concrete frame 203 and the wallboard form an integral whole, which can effectively disperse and transfer the load, avoid stress concentration, improve the stability and load-bearing capacity of the overall structure, and at the same time, enhance the anti-seismic performance of the structure, and ensure the safety of the building under extreme conditions.

[0065] Specifically, the concrete frame 203 comprises a concrete frame beam, a concrete frame column and a concrete plate. The concrete frame serves as the main load-bearing structure of the box house and has high strength and good stability. The longitudinal connecting piece is connected to the concrete frame, which can ensure the stability and safety of the entire box house structure.

[0066] Further, the longitudinal connecting piece comprises a longitudinal connecting piece A3, the longitudinal connecting piece A3 comprises a pre-buried bolt A and a vertical pipeline, the vertical pipeline is inserted into the top of the frame beam, the pre-buried bolt A is located in the frame column and penetrates through the top plate 1 and into the vertical pipeline, and the pre-buried bolt A is fixedly connected with the vertical pipeline.

[0067] Through the fixed connection of the pre-buried bolt A and the vertical pipeline, the frame column of the upper single box house and the frame beam of the lower single box house are firmly connected, and the overall stability of the structure is enhanced. The vertical pipeline is used as a connecting medium, which is convenient for construction and adjustment. At the same time, the pre-buried bolt A is connected and accommodated by the vertical pipeline, and the vertical pipeline is arranged in the frame beam of the lower single box house, without damaging the surface structure of the box house, and the holding force between the longitudinal connecting piece A3 and the frame column of the upper single box house, the top plate 1 of the lower single box house and the frame beam of the lower single box house is better, and the structural stability of the connecting point is strengthened.

[0068] Further, the longitudinal connecting piece comprises a longitudinal connecting piece B4, which is located at a position close to the bottom on the side of the vacancy surface 202.

[0069] The longitudinal connecting piece B4 comprises an L-shaped connecting piece 401 and a plurality of embedded connecting bolts 402, the L-shaped connecting piece 401 is provided with two mutually perpendicular plates, one of the plates is attached to the roof 1, and the other plate is attached to the frame column, wherein a plurality of embedded connecting bolts 402 pass through one of the plates and pass through the roof 1 and are inserted into the frame beam of the lower single box house, and the remaining embedded connecting bolts 402 pass through the other plate and are inserted into the frame column.

[0070] Each of the embedded connecting bolts 402 is fixedly connected to the frame beam or the frame column.

[0071] After stacking and connecting multiple boxes in the longitudinal direction, the connecting node needs to bear the weight from the upper box and the load in the horizontal direction, and the connecting piece is easily damaged under too much pressure. The utility model adopts an L-shaped connecting piece 401 to connect the concrete frame 203 and the roof 1 / ground, the L-shaped connecting piece 401 is provided with two mutually perpendicular plates, and the embedded connecting bolts 402 pass through the plates of the L-shaped connecting piece 401, so that the stress originally concentrated on the embedded connecting bolts 402 can be dispersed to the plates of the L-shaped connecting piece 401, thereby reducing the risk of damage to the structure due to stress concentration.

[0072] Furthermore, the middle part of the L-shaped connecting piece 401 is provided with a partition plate, the partition plate is a right-angled triangular plate, two right-angle edges of the right-angled triangular plate are fixed on the middle lines of two right-angle faces of the L-shaped connecting piece 401 respectively, and the L-shaped connecting piece 401 is also provided with two triangular face plates parallel to the partition plate, and the two triangular face plates are connected to the two sides of the L-shaped connecting piece 401.

[0073] Since the L-shaped connecting piece 401 serves as a longitudinal connecting piece and bears the horizontal and longitudinal load, when subjected to external load, the connecting part is repeatedly pulled, and the L-shaped connecting piece 401 can be deformed, and the two plates can not be attached to the surface of the concrete frame 203 and the roof 1. In order to strengthen the structural stability of the L-shaped connecting piece 401, the utility model is provided with three right-angled triangular steel plates in the middle part and both ends of the L-shaped connecting piece 401 respectively, two right-angle edges of the right-angled triangular steel plate are connected to two plates of the L-shaped connecting piece 401 respectively, the setting of the three right-angled triangular steel plates can disperse the stress transmitted to the two plates of the L-shaped connecting piece 401 to a larger area, reduce the single-point stress, thereby reducing the risk of deformation and damage, prolonging the service life of the L-shaped connecting piece 401 and reducing the fatigue damage caused by repeated load.

[0074] Furthermore, the wall plate is a filled sandwich wall 201.

[0075] To further reduce the stress of the single box houses after longitudinal connection and ensure the safety of hoisting, the utility model sets all the wallboards as filled sandwich walls 201, which are usually made of light materials such as light concrete, foamed plastic or other composite materials. These materials have a lower density, so the overall weight of the wallboards is lighter. This helps to reduce the overall weight of the single box houses after longitudinal connection and reduce the pressure on the hoisting equipment and foundation. At the same time, because the sandwich wall has good heat insulation performance, it can also reduce the influence of temperature on material changes to a certain extent.

[0076] Furthermore, the concrete frame 203 is laid with reinforcing steel bars, which extend along the concrete frame 203 and across the side of the filled sandwich wall 201, and the two ends of the reinforcing steel bars are bent towards the filled sandwich wall 201.

[0077] By wrapping the concrete frame 203 on the outer side of the filled sandwich wall 201, the two ends of the reinforcing steel bars in the concrete frame 203 can extend across the side of the filled sandwich wall and bend towards the filled sandwich wall, so that the concrete frame 203 distributed on the outer side of the filled sandwich wall 201 can be connected to each other to form a complete structure through the internally arranged reinforcing steel bars, thereby enhancing the overall strength and stability of the wall 2 and preventing it from being easily deformed by pulling and knotting during hoisting. The end of the reinforcing steel bar is biased towards the filled sandwich wall 201, which is conducive to the close combination of the reinforcing steel bar and the wall 2, improves the shear resistance and tensile strength, and ensures the safety and durability of the structure.

[0078] Due to the bending of the reinforcing steel bar, it can be reinforced on multiple sides, and the force in one direction can be transmitted to another direction and dispersed to the entire wall, so as to prevent the destruction of the wall structure caused by excessive load or stress concentration, and reduce the risk of damage at the connecting point of the reinforcing steel bar to a certain extent.

[0079] Furthermore, the surface of the joint between the two adjacent single box houses is provided with a rectangular caulking groove 5, and the caulking grooves 5 of the two adjacent single box houses completely cover the joint between the two adjacent single box houses.

[0080] In order to reduce the risk of leakage of the joint between the two adjacent single box houses, a rectangular caulking groove 5 is arranged on the surface of the joint. After installation, the joint between the two single box houses is sealed by caulking, edge sticking and other sealing treatments through the caulking groove 5, so as to prevent cracking and leakage in the later period. The caulking groove 5 completely covers the joint between the two adjacent single box houses, which facilitates smooth and rapid sealing operation of the joint.
