Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated buildings, and in particular relates to a multi-layer modular prefabricated concrete building structure system with energy dissipation and shock absorption. Background Art

[0002] Modular concrete construction is an innovative form of construction that uses modular design and manufacturing technology to break down houses into modules that can be independently manufactured and assembled, and then assembled on site. This form of construction is conducive to the realization of green and sustainable development. Promoting modular construction methods will effectively reduce resource waste and carbon emissions on construction sites.

[0003] Modular concrete buildings refer to a building form that uses a room unit as a prefabricated component unit, which is manufactured in a factory and then transported to the construction site for assembly. Compared with traditional building systems, modular prefabricated buildings have the characteristics of fast assembly, low pollution, and suitability for standardized production. At present, domestic modular concrete buildings are mainly 1 to 3 floors, and are only used in a small number of office, temporary construction, farmhouse and other projects. They have not yet been widely promoted and applied.

[0004] At present, there is no widely promoted modular building system, mainly because the existing technology cannot simultaneously meet the requirements of rapid connection between modules and good stress on the nodes, and cannot meet the multi-scenario use of modular buildings. In terms of the development form of existing modular buildings, the research on modular buildings mostly stays at the building level or only targets a single module. The current modular buildings rely on the nodes of the house for earthquake resistance. Therefore, in order to promote multi-story modular buildings, it is necessary to develop a connector with good earthquake resistance and stable connection. In addition, the existing splicing methods between modules usually choose welding connection or high-strength bolt connection. The construction of these two methods is relatively complicated, which affects the layout flexibility of modular buildings. Therefore, in order to promote modular buildings, it is necessary to consider the convenience, safety, and diversity of combinations of construction methods. Summarizing the above-mentioned characteristic indicators, the present invention provides a modular multi-story building structure system with convenient construction, diverse combinations, safety, energy dissipation and shock absorption based on prefabricated houses, and considering the layout of water and electricity pipe networks, and simple construction.

DETAILED DESCRIPTION

[0021] The technical solution and effects of the present invention are further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0022] In the following description, unless otherwise clearly specified and limited, the terms "set", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integrated connection; it can be a direct connection or an indirect connection, etc. For ordinary technicians in this field, the specific meanings of the above terms in this technical solution can be understood according to specific circumstances.

[0023] The present invention is not limited to the following specific embodiments, and any equivalent changes made on the basis of the technical solution of this application fall within the protection scope of the present invention. The various specific technical features described in the following specific embodiments can be combined in any suitable manner without contradiction, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention. Example 1

[0024] A multi-layer modular assembled concrete building structure system with energy dissipation and shock absorption in this embodiment is a building system composed of a plurality of prefabricated modular room units that are self-locking and interconnected according to design drawings, wherein the structural schematic diagram of the modular room unit is as shown in FIG. Figure 1As shown, it includes a building body, a plurality of vertical self-locking connectors arranged on the building body, and transverse connectors located between the vertical self-locking connectors for transversely connecting modular room units. The modular room units are vertically and transversely connected through the vertical self-locking connectors and the transverse connectors to form a multi-layer modular prefabricated building structure system.

[0025] In the present invention, the vertically adjacent modular room units can be assembled by the vertical self-locking connector. The schematic diagram of the assembly is shown in FIG. Figure 2 and Figure 3 The horizontally adjacent modular room units can be interconnected through the horizontal connectors. The schematic diagram after interconnection is as shown in Figure 4 The main body material of the vertical self-locking connector and the horizontal connector in the present invention is steel.

[0026] The vertical self-locking connector of the present invention is composed of a lock body 4 and a lock groove 5, and is used to assemble vertically adjacent modular room units. The lock grooves 5 are connected to a horizontally penetrating sleeve 503 fixed on the main body of the house. A transverse connector is arranged in two adjacent sleeves 503 of transversely adjacent modular room units, and is used to assemble the transversely adjacent modular room units. Figure 5 and Figure 6 As a specific implementation, two vertical self-locking connectors and a horizontal connector therebetween are used as a group of connector units, and a plurality of connector units are arranged on the main body of the house to connect the modular room units vertically and horizontally to form a multi-layer modular prefabricated building structure system.

[0027] In the present invention, the lock body 4 includes a lock tongue 401 and an elastic member 1 403 for pushing the lock tongue 401. One end of the elastic member 1 403 is fixedly connected to the inner wall of the lock body 4, and the other end is fixedly connected to the lock tongue 401. Figure 7 shown.

[0028] In the present invention, the lock slot 5 includes a lock opening 502 that is connected to the lock tongue 401. Figure 8 As shown, when the lock tongue 401 is close to the lock slot 5, it cooperates with the lock opening 502 to form a self-locking slot that constrains the lock body 4. To further strengthen the self-locking slot, a threaded hole I 402 is set in the lock body 4 (only one end of the threaded hole of the lock slot 5 away from the lock opening 502 is opened to reduce the strength of the lock slot 5 caused by too many holes), and a threaded hole II 501 is also set at the corresponding position of the lock slot 5, as shown in FIG. Fig. 9 As shown, the self-locking groove is further reinforced by high-strength bolts 404 in threaded hole I 402 and threaded hole II 501. The high-strength bolts 404 can be 8.8-grade M20 high-strength bolts.

[0029] In order to have the characteristics of energy dissipation and shock absorption, energy dissipation gaskets 405 are arranged at the bottom of the lock body 4 and the bottom of the lock slot 5. The energy dissipation gasket 405 can be made of high damping rubber, which conforms to the design of national standard GB20688. Various compounding agents are added to natural rubber to improve the damping performance of rubber (increase hysteresis loss and reduce its storage modulus). Rectangular high damping seismic isolation rubber bearings are preferred.

[0030] The working principle of the vertical self-locking connector is as follows: when two vertically adjacent modular room units are assembled, the lock tongue 401 in the lower lock body 4 of one of the upper modular room units is squeezed and retracted into the interior by the lock groove 5 above the lower modular room unit. When the lock tongue 401 drops to the lock opening 502 in the lock groove 5, the lock tongue 401 is pushed by the elastic member 1 403 to snap into the lock opening 502, and then reinforced with high-strength bolts 404, so that the two vertically adjacent modular room units are firmly connected.

[0031] In the present invention, the transverse connecting member provided in the sleeve 503 includes a locking rod 6 that passes through the sleeves 503 of the transversely adjacent modular room units, and a cover plate 601 that is fixed at both ends of the locking rod 6 and is tightly against the sleeve 503, such as Fig.10 and 11 shown.

[0032] like Fig.12 As shown, the locking rod 6 includes a housing and four dampers. Fig.13 As shown, the damper includes a base I 603 and a base II 605, the base I 603 is fixed in the locking rod 6, two base plates 604 are fixed on the base I 603, an energy absorbing component 602 is arranged on the base II 605 (the energy absorbing component 602 can be made of Q235 steel), a sleeve 606 is arranged on the base plate 604 and the energy absorbing component 602, an elastic member II 608 is fixed at the bottom of the sleeve 606, guide tubes 610 are arranged on both sides of the elastic member II 608, a movable top plate 609 is fixedly connected to the elastic member II 608, the guide tube 610 passes through both sides of the movable top plate 609, a force transmission rod 607 is fixedly connected to the center of the movable top plate 609, the force transmission rod 607 in the sleeve 606 on the base plate 604 is fixedly connected to the bottom of the base II 605, and the force transmission rod 607 in the sleeve 606 on the energy absorbing component 602 is fixedly connected to the cover plate 601. As a specific implementation, the force transmission rod 607 can be fixedly connected to the cover plate 601 via a nut.

[0033] In the present invention, the elastic member is a compression spring.

[0034] In the present invention, the main body of the house is assembled from concrete beams 1, concrete columns 2, walls, and floor slabs 3. As a specific implementation, the lock slots on the main body of the house have high-strength bolts, and the lock slots on the concrete columns 2 do not have high-strength bolts.

[0035] The construction method of the building structure system of the present invention is: First, all components are prefabricated in the prefabricated component processing plant. During on-site installation, the lock slots are pre-buried in the concrete beams, and the lock bodies are welded at the corresponding positions of the adjacent modular room units. The upper and lower modular room units are connected to the lock slots through the lock bodies, and energy-absorbing gaskets are added to the bottom of the lock slots. After being connected with high-strength bolts, the floor slabs are assembled. Secondly, the locking rod passes through the sleeve to connect two adjacent modular room units.

[0036] Under the action of a smaller earthquake, the upper modular room unit will vibrate, but the earthquake effect is not enough to overcome the initial resistance caused by the deadweight of the structure and the energy dissipation inside the locking rod and the lock slot. The shapes of the locking rod and the lock slot remain basically unchanged. The seismic energy is converted between the kinetic energy of the structure and the slight plastic deformation of the energy-absorbing components inside the locking rod and the lock slot, so it can be fully used after the earthquake.

[0037] Under the action of a larger earthquake, the earthquake overcomes the initial resistance, and a large lateral displacement occurs between the upper modular room units. The structure obtains passive control force through the internal damper of the locking rod and the internal gasket of the locking groove. Most of the earthquake energy is consumed by the locking rod and the internal gasket of the locking groove. The first damage occurs at the locking rod and the locking groove. The deformation of the concrete column and concrete beam of the house is transferred and concentrated at the locking rod and the locking groove, achieving the effect of energy dissipation and avoiding excessive mutual displacement at the nodes of the concrete column and concrete beam.

[0038] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.

[0039] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
