Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a rapidly constructed prefabricated earthquake-resistant building. Background Art
[0002] Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc. They are representatives of modern industrialized production methods because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications. They involve prefabricated wall panels, prefabricated floor panels and other components.
[0003] In the prior art, as shown in patent No. CN202111552320.4, an assembled prefabricated wall panel, floor slab and its connection structure discloses the connection and assembly relationship between the assembled wall panels and the assembled floor slabs, making the assembly of wall panels and floor slabs in the assembled building more convenient and simple. However, in this scheme, the assembled wall panels and the assembled floor slabs are directly assembled and plugged in, and then fixed. In this way, the assembled wall panels and the assembled floor slabs do not have the effect of consuming energy when subjected to earthquake energy, resulting in poor seismic resistance between the wall panels and floor slabs of the assembled building. Summary of the invention
[0004] In view of this, an object of the present invention is to provide a rapidly constructed prefabricated earthquake-resistant building, so as to improve the earthquake-resistant performance between prefabricated floor slabs and prefabricated wall panels in the prefabricated building.
[0005] In order to achieve the above object, the present invention provides the following technical solutions:
[0006] The present invention discloses a rapidly constructed assembled earthquake-resistant building, comprising a plurality of prefabricated wall panels and prefabricated floor panels that are spliced and fixed, wherein a plurality of plug-in holes and a plurality of plug-in mechanisms matching the plug-in holes are respectively arranged at both ends of the prefabricated wall panels in the height direction, and a plurality of first through holes matching the plug-in mechanisms are arranged at the splicing parts of the prefabricated wall panels of the prefabricated floor panels, and the plug-in mechanisms arranged at the ends of the prefabricated wall panels below the prefabricated floor panels pass through the first through holes and are located in the plug-in through holes at the ends of the prefabricated wall panels above the prefabricated floor panels;
[0007] The plug-in mechanism includes a plug-in steel bar embedded in the prefabricated wall panel, a first limit block fixedly connected to the lower part of the plug-in steel bar is provided, a plurality of energy-absorbing springs and a first energy-absorbing rubber pad are arranged at intervals above the first limit block, the energy-absorbing spring and the first energy-absorbing rubber pad are slidably connected to the plug-in steel bar, a second limit block is provided at the upper end of the plug-in steel bar, and the energy-absorbing spring and the first energy-absorbing rubber pad are both located between the first limit block and the second limit block.
[0008] The working principle of this technical solution is:
[0009] When an earthquake occurs, the prefabricated floor slabs and prefabricated wall panels will receive lateral and vertical moments, which will cause misalignment or separation between the prefabricated floor slabs and prefabricated wall panels. Due to the existence of the plug-in mechanism, when the prefabricated floor slabs and prefabricated wall panels are subjected to lateral moments, they will compress the first energy-absorbing rubber pads. The energy-absorbing rubber pads will consume earthquake energy during the deformation process, thereby improving the stability and seismic resistance of the prefabricated floor slabs and prefabricated wall panels. When subjected to vertical moments, the prefabricated wall panels and prefabricated floor slabs will jump or move up and down. Due to the existence of friction, the first energy-absorbing rubber pads will be driven to move up and down, thereby squeezing the springs between the first energy-absorbing rubber pads, thereby achieving the effect of energy dissipation, thereby improving the seismic resistance of the prefabricated floor slabs and prefabricated wall panels.
[0010] Furthermore, an annular sleeve with a closed end is sleeved on the outer side of the first energy absorbing rubber pad, and a tightening sleeve that presses against the first energy absorbing rubber pad is provided in the middle part of the inner side surface of the closed end of the annular sleeve. The annular sleeve is fixed to the plug-in hole and the first through hole by grouting. The benefit lies in that the provision of the annular sleeve improves the connection stability between the plug-in mechanism and the prefabricated floor slabs and prefabricated wall panels, and at the same time improves the extrusion effect during movement. The provision of the tightening sleeve directly squeezes the first energy absorbing rubber pad when the prefabricated wall panel moves downward or jumps, thereby improving the energy dissipation effect.
[0011] Furthermore, a traction rope slidably connected thereto is symmetrically provided on the edge of the closed end of the annular sleeve, one end of the traction rope is located outside the closed end of the annular sleeve, and the other end of the traction rope passes through a plurality of first energy-absorbing rubber pads, and limiting balls are provided on both ends of the traction rope.
[0012] The advantage is that the setting of the traction rope forms the annular sleeve and the inserted steel bar into a whole, that is, the up and down movement of the annular sleeve will drive the movement of the traction rope, that is, the traction rope will directly drive the first energy-absorbing rubber pad at the lower end to slide, gradually squeeze the energy-absorbing spring upwards, and then realize energy consumption, and the setting of the tightening sleeve is that the downward movement of the annular sleeve gradually squeezes the energy-absorbing spring from the upper end to achieve energy consumption.
[0013] Furthermore, the other end of the traction rope also passes through the first limit block, and a limit ball is provided on the lower surface of the first energy-absorbing rubber pad located at the bottom of the traction rope. An installation spacing is provided between the end of the traction rope passing through the first limit block and the first limit block. The advantage is that the length of the installation spacing can be adjusted, that is, the upward displacement of the traction rope is limited without affecting the moving energy consumption of the traction rope, thereby avoiding the problem of detachment caused by excessive displacement, thereby further improving the stability and safety of the assembled building.
[0014] Furthermore, the prefabricated wall panels and prefabricated floor panels are provided with grouting holes, and the grouting holes are respectively connected with the plug-in holes and the first through holes, and grouting channels are provided between the adjacent plug-in holes and the first through holes. The advantage is that grouting concrete can be injected from the grouting holes, and grouting operations in various parts can be achieved through the grouting channels.
[0015] Furthermore, a second energy-absorbing rubber pad is provided between the contact surfaces of the prefabricated wall panel and the prefabricated floor panel, and the second energy-absorbing rubber pad is provided with a second through hole matching the first through hole. The benefit is that the second energy-absorbing rubber pad can avoid rigid contact between the prefabricated floor panel and the prefabricated wall panel, and at the same time can also play an energy-absorbing and buffering role for vertical torque.
[0016] Furthermore, the edges of the prefabricated floor slabs and prefabricated wall panels that are in contact with the second energy absorbing rubber pad are both provided with sloped surfaces, and the sloped surfaces are squeezed on the edges of the second energy absorbing rubber pads. The advantage of this is that, during grouting, the contact surfaces of the prefabricated floor slabs and the prefabricated wall surfaces need to be sealed to avoid leakage (as known in the prior art). However, in the present technical solution, the sloped surface squeezes the edge of the second energy absorbing rubber pad, which will squeeze and compress the edge of the second shock-absorbing energy absorbing rubber inward, thereby making it in close contact with the annular sleeve, thereby sealing the gap between the annular sleeve and the second through hole, and then realizing direct grouting operation without the need for subsequent sealing operation, thereby improving the assembly speed and grouting effect.
[0017] Furthermore, roller mechanisms and slide grooves are respectively provided on the side surfaces of the adjacent prefabricated floor slab connections. The advantage thereof is that, during hoisting and assembly, it is only necessary to align the positions of the rollers and the slide grooves to achieve positioning between the annular sleeve, the plug-in hole and the first through hole. When hoisting is not required, a mirror can be placed between the contact surfaces to observe whether the plug-in parts are aligned, thereby further improving the assembly effect and speed.
[0018] The technical effects achieved by this technical solution are as follows:
[0019] (1) The setting of the plug-in mechanism of the technical solution enables the assembly shock absorption to have the effect of shock absorption and energy consumption; (2) The setting of the slope surface, roller mechanism and slide groove improves the efficiency of assembly and grouting, that is, the various parts of the building can be assembled quickly.
[0020] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art may be taught from the practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0034] like Figures 1 to 10As shown, the present invention is a rapidly constructed assembled earthquake-resistant building. It should be noted that other parts of the assembled building are existing technologies and will not be described in detail here. In the present technical solution, the main emphasis is on the earthquake-resistant connection relationship between the prefabricated wall panels 1 and the prefabricated floor panels 2 in the assembled building, and the prefabricated wall panels 1 and the prefabricated floor panels 2 are processed in the factory and then transported to the construction site for hoisting and assembly.
[0035] Specifically, the technical solution includes a plurality of prefabricated wall panels 1 and prefabricated floor panels 2 that are spliced and fixed. A plurality of plug holes 3 and a plurality of plug mechanisms 4 that match the plug holes 3 are respectively provided at both ends of the prefabricated wall panels 1 in the height direction. The prefabricated floor panels 2 are provided with a plurality of first through holes 5 that match the plug mechanisms 4 at the splicing portion of the prefabricated wall panels 1. The plug mechanisms 4 that are provided at the ends of the prefabricated wall panels 1 below the prefabricated floor panels 2 pass through the first through holes 5 and are located in the plug through holes at the ends of the prefabricated wall panels 1 above the prefabricated floor panels 2.
[0036] The plug-in mechanism 4 includes a plug-in steel bar 41 embedded in the prefabricated wall panel 1, and a first limit block 42 fixedly connected to the lower part of the plug-in steel bar 41 is provided, and a plurality of energy-absorbing springs 45 and a first energy-absorbing rubber pad 44 are arranged at intervals above the first limit block 42. The energy-absorbing spring 45 and the first energy-absorbing rubber pad 44 are slidably connected to the plug-in steel bar 41, and a second limit block 49 is provided at the upper end of the plug-in steel bar 41. The energy-absorbing spring 45 and the first energy-absorbing rubber pad 44 are both located between the first limit block 42 and the second limit block 49. It should be noted that the first limit block 42 and the second limit block 49 are fixed to the plug-in steel bar 41 by welding, and the shape of the first energy-absorbing rubber pad 44 is cylindrical. The material of the first limit block 42 and the second limit block 49 can be iron, and its diameter is smaller than the first energy-absorbing rubber pad 44 to avoid extrusion interference.
[0037] It should be noted that, in the prior art, when realizing the assembly connection between prefabricated wall panels 1, a plug-in steel bar 41 is usually preset at one end, and after the plug-in steel bar 41 is inserted into the plug-in hole 3, a grouting process is performed.
[0038] The working principle of this technical solution is:
[0039] When an earthquake occurs, the prefabricated floor 2 and the prefabricated wall panel 1 will receive lateral and vertical moments, which will cause misalignment or separation between the prefabricated floor 2 and the prefabricated wall panel 1. Due to the presence of the plug-in mechanism 4, when the prefabricated floor 2 and the prefabricated wall panel 1 are subjected to lateral moments, they will compress the first energy-absorbing rubber pads 44. The energy-absorbing rubber pads will consume earthquake energy during the deformation process, thereby improving the stability and seismic resistance of the prefabricated floor 2 and the prefabricated wall panel 1. When subjected to vertical moments, the prefabricated wall panel 1 and the prefabricated floor 2 will jump or move up and down. Due to the existence of friction, the first energy-absorbing rubber pads 44 will be driven to move up and down, thereby squeezing the springs between the first energy-absorbing rubber pads 44, thereby achieving the effect of energy dissipation, thereby improving the seismic resistance of the prefabricated floor 2 and the prefabricated wall panel 1.
[0040] An annular sleeve 43 with a closed end is sleeved on the outer side of the first energy dissipation rubber pad 44, and a pressing sleeve 48 is provided in the middle of the inner side surface of the closed end of the annular sleeve 43, which is pressed against the first energy dissipation rubber pad 44. The annular sleeve 43 is fixed to the plug-in hole 3 and the first through hole 5 by grouting. The setting of the annular sleeve 43 improves the connection stability between the plug-in mechanism 4 and the prefabricated floor slab 2 and the prefabricated wall panel 1, and at the same time improves the extrusion effect during movement. The setting of the pressing sleeve 48 directly squeezes the first energy dissipation rubber pad 44 when the prefabricated wall panel 1 moves downward or jumps, thereby improving the energy dissipation effect.
[0041] A traction rope 46 slidably connected to the closed end edge of the annular sleeve 43 is symmetrically provided, one end of the traction rope 46 is located outside the closed end of the annular sleeve 43, and the other end of the traction rope 46 passes through a plurality of first energy-absorbing rubber pads 44. Limiting balls 47 are provided on both ends of the traction rope 46. The traction rope 46 can be a steel wire rope, and the limiting ball 47 can be a steel ball, etc. The steel ball is fixed to the traction rope 46 by a clip or other means.
[0042] The setting of the traction rope 46 forms the annular sleeve 43 and the inserted steel bar 41 into a whole, that is, the up and down movement of the annular sleeve 43 will drive the traction rope 46 to move, that is, the traction rope 46 will directly drive the first energy-absorbing rubber pad 44 at the lower end to slide, gradually squeeze the energy-absorbing spring 45 upward, and then realize energy consumption, and the setting of the tightening sleeve 48 is that the downward movement of the annular sleeve 43 gradually squeezes the energy-absorbing spring 45 from the upper end to consume energy.
[0043] The other end of the traction rope 46 also passes through the first limit block 42. A limit ball 47 is provided on the lower surface of the first energy-absorbing rubber pad 44 at the bottom of the traction rope 46. An installation spacing is provided between one end of the traction rope 46 passing through the first limit block 42 and the first limit block 42. The length of the installation spacing can be adjusted, that is, without affecting the moving energy consumption of the traction rope 46, the upward displacement of the traction rope 46 is limited to avoid the problem of detachment caused by excessive displacement, which further improves the stability and safety of the assembled building.
[0044] The prefabricated wall panel 1 and the prefabricated floor panel 2 are both provided with grouting holes 8, which are respectively connected to the plug-in hole 3 and the first through hole 5. A grouting channel 9 is provided between the adjacent plug-in hole 3 and the first through hole 5. Grouting concrete 10 is injected from the grouting hole 8, and the grouting operation of each part can be realized through the grouting channel 9. Of course, the description in the present technical scheme is that the grouting is completed at one time, and the grouting can also be carried out in different regions as in the prior art to further ensure the grouting effect. The grouting hole 8 should include a feed hole and a discharge hole in this specific embodiment, which will not be described in detail here.
[0045] A second energy-absorbing rubber pad 6 is provided between the contact surfaces of the prefabricated wall panel 1 and the prefabricated floor slab 2. The second energy-absorbing rubber pad 6 is provided with a second through hole matching the first through hole 5. The second energy-absorbing rubber pad 6 can avoid rigid contact between the prefabricated floor slab 2 and the prefabricated wall panel 1, and at the same time can also play an energy-absorbing and buffering role for vertical torque.
[0046] The edges of the prefabricated floor 2 and the prefabricated wall panel 1 that are in contact with the second energy absorbing rubber pad 6 are both provided with a slope surface 7, and the slope surface 7 acts on the edge of the second energy absorbing rubber pad 6 by squeezing. When grouting, the contact surface between the prefabricated floor 2 and the prefabricated wall surface needs to be sealed to avoid leakage (known in the prior art). However, in the present technical solution, the slope surface 7 squeezes the edge of the second energy absorbing rubber pad 6, which will squeeze and compress the edge of the second shock-absorbing energy absorbing rubber inward, so that it is in close contact with the annular sleeve 43, and the gap between the annular sleeve 43 and the second through hole can be sealed, thereby realizing direct grouting operation without the need for subsequent sealing operation, thereby improving the assembly speed and grouting effect.
[0047] Roller mechanisms and slide grooves are respectively provided on the side surfaces of the connection points of adjacent prefabricated floor slabs 2. During hoisting and assembly, it is only necessary to align the positions of the rollers and the slide grooves to achieve positioning between the annular sleeve 43, the plug-in hole 3 and the first through hole 5. When hoisting is not required, a mirror can be placed between the contact surfaces to observe whether the plug-in parts are aligned, thereby further improving the assembly effect and speed. It should be noted that this part is not drawn in the figure. The roller mechanism includes a connecting rod and a roller. One end of the connecting rod is hinged to the outer surface of the lower prefabricated wall panel 1, and the roller is connected to the other end of the connecting rod. The positions of the rollers and the slide grooves are fixed and have been set at the factory. Therefore, during hoisting, as long as the positions of the rollers and the slide grooves correspond, the positions of the plug-in mechanism 4 and the plug-in hole 3 should be aligned accordingly.
[0048] It should be further explained that the plug-in mechanism 4 in the present technical solution can be prefabricated and assembled on the wall panel in the factory. The prefabrication method is simple. The specific prefabrication steps can be: first, weld the first limit block 42 on the plug-in steel bar 41, and then sleeve the energy-absorbing spring 45 and the first energy-absorbing rubber pad 44 on the first plug-in steel bar 41, and then weld the second limit block 49 at the end of the plug-in steel bar 41, and then assemble the traction rope 46 on the annular sleeve 43, and then pass the traction rope 46 through the first energy-absorbing rubber pad 44 and the first limit block 42, and then clamp and fix the limit ball 47 in a suitable position, and finally adjust the length of the traction rope 46 appropriately. In the present technical solution, the first energy-absorbing rubber pad 44 and the second energy-absorbing rubber pad 6 are adopted because they have the ability to deform and absorb energy and are relatively wear-resistant. Of course, energy-absorbing components made of other materials can also be used.
[0049] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
