Description

Technical Field

[0001] This invention belongs to the field of building structure and construction technology, and relates to a seismic-resistant reinforced concrete prefabricated house assembled with box-shaped components and its construction method. Background Technology

[0002] The demands of building structural engineering have spurred the rapid development of reinforced concrete components. Traditional cast-in-place reinforced concrete structures require on-site reinforcement binding, formwork erection, concrete pouring, and formwork removal, resulting in high on-site labor requirements and long construction periods. With the rapid pace of urbanization and the increasing level of industrialization in the construction industry, higher demands are being placed not only on the structural design and performance requirements of reinforced concrete components, but also on the fabrication processes and the rationality of their installation.

[0003] To overcome the shortcomings and deficiencies of traditional cement box houses, it is necessary to seek more reasonable solutions in terms of structural technology and construction methods to meet the needs of building construction, while ensuring that the assembled houses meet earthquake resistance standards, thereby forming buildings that are easy to process, highly prefabricated, require less on-site labor, and have a fast construction speed. Summary of the Invention

[0004] This invention provides a seismic-resistant reinforced concrete prefabricated house assembled from box-shaped components and its construction method. The house includes multiple prefabricated reinforced concrete box-shaped components in a factory and connection nodes between these components. The box-shaped components are transported to the construction site and assembled through the connection nodes to form the prefabricated house. The prefabricated house has the following advantages: high construction efficiency, high degree of prefabrication, flexible assembly methods, and good structural performance.

[0005] The prefabricated houses can also meet seismic requirements, thus overcoming the long-standing problem of traditional cement box houses being simply stacked together with components that are not connected to each other, making it difficult to meet seismic codes.

[0006] In a first aspect, the present invention provides a seismically resistant reinforced concrete prefabricated house assembled from box-shaped components. The house includes a plurality of prefabricated reinforced concrete box-shaped components and connection nodes between the box-shaped components.

[0007] The box-shaped component has two longitudinal wall panels, two end wall panels, and a top panel. The end wall panels can be optionally provided with door openings or windows, and the longitudinal wall panels can be optionally provided with door and window openings or large openings. In addition, the top of the end wall panels can be optionally provided with an eave. When the longitudinal wall panels and end wall panels are used as exterior wall panels, they are provided with a thermal insulation layer. The top panel can be a flat top panel or a pitched top panel, thereby forming a flat-top box-shaped component and a pitched-roof box-shaped component, respectively.

[0008] The connection nodes include horizontal connection nodes on the outer wall, horizontal connection nodes on the inner wall, large opening nodes on the inner wall, connection nodes at the floor slab, end connection nodes of adjacent left and right box modules, and vertical connection nodes of adjacent left and right box modules.

[0009] The box-shaped components can be arranged left and right and / or front and back to assemble into a multi-unit single-layer spatial structure, thereby forming a single-layer prefabricated house;

[0010] The single-layer spatial structure can be stacked to form a multi-layer spatial structure, wherein the top layer of the house can use the flat-roof box-shaped component or the pitched-roof box-shaped component, thereby forming a multi-layer prefabricated house with a flat roof or a pitched roof.

[0011] One or each of the two longitudinal wall panels of the box-shaped component has a large opening, so that the large openings of adjacent box-shaped components can be connected to each other to form a combined space during on-site assembly;

[0012] The single-story prefabricated house has a single-story spatial structure that is either a parallel two-unit structure or a parallel combined multi-unit structure.

[0013] Preferably, the single-story prefabricated house has a single-story spatial structure that is an array-combined multi-unit structure.

[0014] The box-shaped components in the array combination multi-unit structure can be box-shaped components with eaves. In the array combination, the eaves of the box-shaped components are opposite each other, so that a corridor space is formed below the splicing of the eaves and connects with the door openings on both sides.

[0015] The multi-story prefabricated house has a multi-story spatial structure composed of superimposed single-story spatial structures.

[0016] The connection nodes between the box-shaped components are as follows:

[0017] The external wall horizontal connection node is used to form a fixed connection between the external walls of adjacent box-shaped components. It includes a recess provided on the inner side of the external wall of the box-shaped component and a connecting rod with an end. The recess is provided with a through hole near another box-shaped component and can communicate with the hole at the corresponding assembly position of the other box-shaped component, so that the connecting rod can pass through and be fixed with the through hole and the hole, while the end of the connecting rod remains inside the recess to form a tight connection between the adjacent box-shaped components.

[0018] The horizontal connection node of the inner wall is used to form a fixed connection between the inner walls of parallel box-shaped components and between the inner walls of arrayed box-shaped components, including setting a steel mesh formed by longitudinal and transverse steel bars at the modular assembly part of the box-shaped component; and pouring concrete at the node during on-site assembly.

[0019] The large opening node in the inner wall is used to form a fixed connection on the side of the large opening between box-shaped components with large openings in the longitudinal wall panels of the inner wall. It includes a steel reinforcement component formed by a combination of longitudinal steel bars and transverse steel rings between the wall panels. Concrete is poured at the node during on-site assembly.

[0020] The connection node at the floor slab is used to form a fixed connection between the floor slabs of the parallel box-shaped components. It includes opening dovetail grooves at corresponding positions on both sides of the floor slab, in which steel bars or embedded parts can be installed; concrete is poured at the node during on-site assembly.

[0021] The left and right adjacent box-shaped module end connection node is used to form a fixed connection at the ends of the left and right adjacent box-shaped modules, including setting a U-shaped steel plug module at the end of the module and pouring concrete at the end between the left and right adjacent box-shaped modules; wherein the U-shaped steel plug module includes a U-shaped steel and a plurality of horizontal perforations set at a set interval along its longitudinal direction, and a plug is formed by passing through the perforations and horizontally inserting into the end and forming a fixed connection with the poured concrete.

[0022] The vertical connection nodes of the left and right adjacent box modules include multiple horizontal through holes set at a set interval in the vertical direction of the left and right adjacent box modules, and through bolts passing through the through holes and horizontally inserted into the adjacent box modules, as well as fixing nuts at both ends, so as to form a vertical fixed connection of the modules together with the concrete poured between the modules.

[0023] Preferably, the box-shaped component itself is a spatial thin-walled structure.

[0024] In a second aspect, the present invention provides a method for constructing a seismically resistant reinforced concrete prefabricated house assembled from the aforementioned box-shaped components, comprising the following steps:

[0025] (1) Multiple reinforced concrete box-shaped components are manufactured in a factory, wherein the box-shaped components themselves are spatial thin-walled structures;

[0026] (2) Transport the box-shaped components to the house construction site;

[0027] (3) On the base surface, according to the design requirements, the box-shaped components are hoisted into place and arranged left and right to form a multi-unit parallel single-layer spatial structure. They can also be further spliced ​​and combined front and back to form an array of single-layer spatial structures. The connection nodes between the box-shaped components are fixed, including the external wall horizontal connection node, the internal wall horizontal connection node, the internal wall opening node, the floor slab connection node, the end connection nodes of the left and right adjacent box-shaped modules, and the vertical connection nodes of the left and right adjacent box-shaped modules.

[0028] (4) Pour concrete into the joints and connection nodes of the single-layer space structure; and pour concrete into the floor of the single-layer space structure.

[0029] (5) Based on the design requirements, steps (3) and (4) can be repeated on the basis of the above single-layer structure space with the flat top plate as the base to form a multi-layer space structure.

[0030] (6) Construct a roof above the single-story spatial structure in step (4) or the multi-story spatial structure in step (5) according to the design, including the option to use the pitched roof box-shaped component on the top floor, thereby forming a single-story or multi-story box-shaped component assembly of a seismic reinforced concrete prefabricated house.

[0031] The earthquake-resistant reinforced concrete prefabricated house assembled with the box-shaped components and the construction method thereof provided by the present invention have the following advantages:

[0032] Highly efficient construction: Approximately 80% of the work can be completed in the factory, with only box assembly, minor decoration, and pipeline connection required on site. The construction period is shortened by about 50%-70% compared to traditional construction methods.

[0033] High degree of prefabrication: On-site labor accounts for only about 20% of the total labor, which is 30%-50% less than that of brick-concrete buildings, and can improve the working conditions of workers;

[0034] Flexible assembly method, with upper and lower boxes overlapping for assembly: multi-story houses can be built; fast construction speed and short construction period; high degree of prefabrication, requiring less on-site labor; high structural rigidity.

[0035] Meets seismic requirements: The concrete box-shaped components themselves have high rigidity and reasonable connection node design, which can meet the seismic requirements, thus overcoming the long-standing problem that traditional box-shaped prefabricated houses cannot meet seismic codes.
