Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and particularly to a prefabricated energy-saving and sound-insulating building and its assembly method. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to a factory. Building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory and transported to the construction site, and then assembled and installed on-site through reliable connection methods.

[0003] For the installation of the walls and columns of a prefabricated building, they are usually hoisted in place first, and then connected to the steel bars on the bottom surface through the sleeves inside the walls and columns. Finally, by pouring cement mortar, the sleeves and steel bars are firmly connected, thereby realizing the installation and connection of the walls and columns, and the connection is fast and convenient.

[0004] However, during the installation and connection process, it is difficult to align the steel bars and sleeves. Workers need to hold a reflector to check whether the steel bars and sleeves are aligned, resulting in low installation efficiency. At the same time, the connection between the steel bars and sleeves is not firm enough, resulting in poor seismic performance of the building.

[0005] Therefore, a prefabricated energy-saving and sound-insulating building is needed to solve the above technical problems. Summary of the Invention

[0047] 5-column body. Specific implementation mode

[0048] The present invention will be specifically described below in conjunction with the accompanying drawings. As Figures 1 - 13 shown, an assembled energy-saving sound-insulating building includes a connecting component 1. The connecting components 1 are evenly distributed at the lower end of the column body 5 or at the lower edge of the wall body. The column body 5 or the wall body is connected to the steel bars on the bottom surface through the connecting component 1 to realize the assembly of the wall body or the column body 5. A grouting port 11 is provided at the top end of the connecting component 1, and the grouting port 11 protrudes from the outer surface of the column body 5 or the wall body; the wall body adopts a hollow structure. Through the hollow structure, the weight of the wall body can be reduced, the weight and structural size of the building can be reduced, and at the same time, the hollow structure can achieve the functions of sound insulation and heat preservation;

[0049] See Figures 2 - 4 , the connecting component 1 includes a sleeve 12. A plurality of fins 123 are evenly distributed on the outer side of the sleeve 12. The fins 123 are used to tightly connect the sleeve 12 with the wall body or the column body 5. The upper end of the sleeve 12 is welded with a hollow upper sleeve 121. A grouting port 11 is provided at the top end of the upper sleeve 121. After the installation is completed, slurry is poured into the connecting component 1 through the grouting port 11 to realize the tight connection between the connecting component 1 and the steel bars. The lower end of the sleeve 12 is welded with a lower sleeve 122. The lower end of the lower sleeve 122 is arranged on the lower bottom surface of the column body or the wall body. An extrusion cylinder 13 is slidably arranged up and down in the lower sleeve 122. The upper end of the extrusion cylinder 13 is fixedly connected with an upper sliding cylinder 16. The upper sliding cylinder 16 is slidably arranged in the sleeve 12. A plurality of force-increasing components 2 are evenly distributed in the circumferential direction of the upper sliding cylinder 16. By moving the upper sliding cylinder 16 upward, the force-increasing components 2 are driven to move, and the steel bars inserted into the upper sliding cylinder 16 are bite-fixed through the force-increasing components 2 to realize the tight fixation between the steel bars and the connecting component 1;

[0050] See Figure 5 and Figure 6 , the upper end of the upper sliding cylinder 16 is welded with a support ring 161. A first spring 162 is provided at the upper end of the support ring 161. The upper end of the first spring 162 is connected to an upper retaining ring 1211. The upper retaining ring 1211 is arranged in the upper sleeve 121. Through the arrangement of the first spring 162, before installation, the upper sliding cylinder 16 is kept at the bottom of the sleeve 12 to facilitate the smooth progress of the installation.

[0051] Further, see Figure 3 , the lower end of the extrusion cylinder 13 is welded with a guide block 14. A circular guide inclined surface 141 is arranged in the guide block 14. A guide inner cylinder 142 is arranged at the upper end of the guide inclined surface 141. Through the arrangement of the guide inclined surface 141 and the guide inner cylinder 142, it is convenient for the steel bars to smoothly enter the connecting component 1 and guide the steel bars to facilitate the steel bars to enter between the force-increasing components 2.

[0052] Further, seeFigure 4 , Figure 9 and Figure 10 , thrust bearings 17 are arranged at the upper and lower ends of the force increasing component 2. The outer sleeve of the thrust bearing 17 is connected to the rotating cylinder 18. A plurality of extrusion arc blocks 182 are circumferentially and evenly distributed on the inner circumference of the rotating cylinder 18. Along the circumferential direction, the radial thickness of the extrusion arc block 182 gradually increases. A lower baffle 181 is welded to the lower end of the rotating cylinder 18. The upper side of the rotating cylinder 18 and the lower side of the lower baffle 181 are both abutted against the thrust bearing 17; by arranging the thrust bearing 17, it is convenient for the rotating cylinder 18 to rotate relative to the upper sliding cylinder 16;

[0053] A driving sleeve 19 is fixedly sleeved outside the rotating cylinder 18. A plurality of driving inclined grooves 191 are evenly distributed on the outside of the driving sleeve 19. A sliding column 124 is slidably connected in the driving inclined groove 191. The sliding column 124 is fixedly arranged on the inner wall of the sleeve 12; through the arrangement of the driving inclined groove 191 and the sliding column 124, when the upper sliding cylinder 16 slides up and down, the sliding column 124 drives the driving sleeve 19 and the rotating cylinder 18 to rotate by squeezing the driving inclined groove 191. When the rotating cylinder 18 rotates, the force increasing component 2 is squeezed by the extrusion arc block 182, realizing the bite fixation of the force increasing component 2 on the steel bar.

[0054] Further, referring to Figure 7 and Figure 8 , the force increasing component 2 includes a rectangular hollow housing 21. End covers 22 are bolted to both ends of the housing 21. An extrusion block 23 is slidably connected in the housing 21. A limiting plate 231 is arranged in the middle of the extrusion block 23. The limiting plate 231 abuts against the inner side of the end cover 22. One end of the extrusion block 23 away from the housing 21 is provided with an inclined surface 232. The inclined surface 232 abuts against the surface of the extrusion arc block 182 of the rotating cylinder 18;

[0055] Two inclined surfaces 233 are symmetrically arranged at one end of the extrusion block 23 away from the inclined surface 232. The surfaces of the two inclined surfaces 233 abut against the middle rolling ring 262. The middle rolling ring 262 is rotatably sleeved on the middle of the rolling shaft 26. End rolling rings 261 are rotatably sleeved at both ends of the rolling shaft 26. A positioning ring is arranged between the end rolling ring 261 and the middle rolling ring 262. The rolling shaft 26 slides in the waist-shaped chute 211 on the side surface of the housing 21. The sliding direction of the rolling shaft 26 is perpendicular to the sliding direction of the extrusion block 23.

[0056] By sliding the extrusion block 23, the two inclined surfaces 233 of the extrusion block 23 will squeeze the middle rolling ring 262, and the middle rolling ring 262 drives the rolling shaft 26 and the end rolling ring 261 to slide away from each other in the waist-shaped chute 211.

[0057] Further, the end rolling ring 261 rolls on the surface of the inclined surface 242. The inclined surface 242 is symmetrically arranged at one end of the telescopic block 24 close to the extrusion block 23. The telescopic block 24 is provided with a rectangular blind hole that can accommodate the inclined surface 233;

[0058] Flanges are provided on the mutually remote sides of the inclined surface three 242. A plurality of second springs 243 are fixedly connected to the side of the flange remote from the extrusion block 23. The other ends of the second springs 243 abut against the end cover 22. The telescopic block 24 is driven by the second springs 243 to be in a state of being retracted into the housing 21. The inclined surface three 242 of the telescopic block 24 drives the two rollers 26 to be in a state of approaching each other. The middle rolling ring 262 on the roller 26 presses the inclined surface two 233, so that the extrusion block 23 is in a state of being remote from the telescopic block 24;

[0059] The angle of the acute angle between the inclined surfaces three 242 is greater than the angle of the acute angle between the inclined surfaces two 233. Through the angle settings of the inclined surfaces three 242 and two 233, the distance that the extrusion block 23 moves is greater than the telescopic distance of the telescopic block 24, so that the thrust provided by the telescopic block 24 is greater than the pressure received by the extrusion block 23, thereby achieving a force-increasing effect and improving the extrusion force of the telescopic block 24 on the steel bar.

[0060] Further, a dovetail groove 241 is provided in the vertical direction at the end of the telescopic block 24 remote from the extrusion block 23. A slide bar 25 is vertically slidably arranged in the dovetail groove 241. A plurality of teeth 251 are evenly distributed in the vertical direction on the side of the slide bar 25 remote from the telescopic block 24, and the teeth 251 are horizontally arranged; through the telescoping of the telescopic block 24, the teeth 251 are driven to telescope, and the teeth 251 are clamped and engaged in the steel bar, realizing a stable clamping connection between the teeth 251 and the steel bar and preventing the steel bar from falling off;

[0061] Both the upper and lower ends of the slide bar 25 are bolted with limit bars 252, and the slide bar 25 is kept in the dovetail groove 241 of the telescopic block 24 through the limit bars 252.

[0062] Further, the force-increasing assemblies 2, the driving inclined grooves 191 and the sliding columns 124 are all provided in three. Through the settings of the three force-increasing assemblies 2, the driving inclined grooves 191 and the sliding columns 124, the force on the steel bar can be made uniform, and at the same time, the structure is simplified.

[0063] Further, referring to Figure 3 and Figures 11 - 13 , the top end of the extrusion cylinder 13 is fixedly connected to the top end of the lower sliding cylinder 15. The extrusion cylinder 13 is movably sleeved outside the lower sliding cylinder 15. A limit shoulder 131 is provided in the middle of the extrusion cylinder 13. The limit shoulder 131 is used to enable the lower end of the lower sliding cylinder 15 to abut against the shoulder 131 after the extrusion cylinder 13 is extruded and deformed, realizing the axial relative fixation between the extrusion cylinder 13 and the lower sliding cylinder 15;

[0064] An upper annular groove 135 is provided on the outer side of the upper end of the extrusion cylinder 13, and a lower annular groove 134 is provided below the upper annular groove 135. An inner annular groove 136 is provided between the upper annular groove 135 and the lower annular groove 134 on the inner side of the extrusion cylinder 13. Through the settings of the upper annular groove 135, the lower annular groove 134 and the inner annular groove 136, the extrusion cylinder 13 is more likely to deform when subjected to an extrusion force;

[0065] See Figure 3 , during installation, the extrusion cylinder 13 is restricted by the lower sleeve 122 and the lower sliding cylinder 15, and the extrusion cylinder 13 will not produce bending deformation. When the extrusion cylinder 13 moves upward, the upper annular groove 135, the inner annular groove 136 and the lower annular groove 134 on the extrusion cylinder 13 are successively released from the restriction of the lower sleeve 122, and the extrusion cylinder 13 undergoes complete deformation successively at the positions of the upper annular groove 135, the inner annular groove 136 and the lower annular groove 134 until the limiting shoulder 131 abuts against the lower end of the lower sliding cylinder 15, and the extrusion cylinder 13 deforms into Figure 13 the described state. At this time, the force of the extrusion cylinder 13 is directly transmitted to the lower end of the lower sliding cylinder 15, and at this time, the extrusion cylinder 13 no longer undergoes bending deformation;

[0066] The deformed part of the extrusion cylinder 13 is located in the space between the lower baffle 181 and the lower sleeve 122. When grouting is installed, the deformed part of the extrusion cylinder 13 can act as a connecting rib, making the connection between the lower sliding cylinder 15, the extrusion cylinder 13 and the sleeve 12 more stable.

[0067] Furthermore, see Figure 11 and Figure 3 , a plurality of vertically arranged first through grooves 132 are circumferentially and uniformly distributed at the upper end of the extrusion cylinder 13, and a plurality of vertically arranged second through grooves 151 are circumferentially and uniformly distributed on the lower sliding cylinder 15. The first through grooves 132 and the second through grooves 151 are the same in size and coincide in position with each other;

[0068] A plurality of vertically arranged third through grooves are circumferentially and uniformly distributed on the upper sliding cylinder 16; through the settings of the first through grooves 132, the second through grooves 151 and the third through grooves, when grouting, the slurry can enter the sleeve 12 through the first through grooves 132, the second through grooves 151 and the third through grooves. When the slurry solidifies, the positions of the various components in the connecting assembly 1 are fixed.

[0069] Working principle: The column 5 or the wall body provided with the connecting assembly 1 is lifted by a tower crane to the position where it needs to be installed, and the lifted column 5 or the wall body is brought close to the steel bars at the bottom surface, so that the guide block 14 is close to the steel bars. By observing the relative positions of the guide block 14 and the steel bars, it is judged whether the steel bars and the connecting assembly 1 are aligned, which improves the convenience of installation;

[0070] The column 5 or the wall body is moved downward, and the steel bars enter between the slide bars 25 of the force increasing assembly 2 through the guide inner cylinder 142 until the guide block 14 contacts the bottom surface, and then the column 5 or the wall body continues to move downward;

[0071] At this time, the guiding block 14 and the steel bar move into the column body 5 or the wall together. The guiding block 14 pushes the extrusion cylinder 13, the lower sliding cylinder 15 and the upper sliding cylinder 16 to move upward. The upper sliding cylinder 16 drives the force increasing assembly 2, the rotating cylinder 18 and the driving sleeve 19 to move upward. The driving inclined groove 191 on the outer side of the driving sleeve 19 slides relative to the sliding column 124, and the sliding column 124 drives the rotating cylinder 18 and the driving sleeve 19 to rotate;

[0072] The extrusion arc block 182 in the rotating cylinder 18 extrudes the extrusion block 23. The inclined surface 232 of the extrusion block 23 drives the two rollers 26 to move away from each other. The rollers 26 drive the telescopic block 24 and the sliding strip 25 to extend out. The sliding strip 25 extrudes the steel bar to achieve stable clamping of the steel bar; until the upper side of the rotating cylinder 18 contacts the inner wall of the upper end of the sleeve 12, at this time the sliding strip 25 stops extruding the steel bar;

[0073] Subsequently, the column body 5 or the wall moves downward, and the extrusion cylinder 13 continues to move upward. Since the rotating cylinder 18, the lower sliding cylinder 15 and the upper sliding cylinder 16 no longer move relative to the sleeve 12, at this time the extrusion cylinder 13 is extruded and deformed. The deformed part of the extrusion cylinder 13 is located in the space between the lower baffle 181 and the lower sleeve 122. When the column body 5 or the wall contacts the bottom surface, the extrusion cylinder 13 no longer deforms;

[0074] Finally, slurry is poured into the connecting assembly 1 through the grouting port 11. The slurry enters each part in the connecting assembly 1 through the first through groove 132, the second through groove 151 and the third through groove. When the slurry solidifies, the complete fixation of the connecting assembly 1 is realized. Since the engaging teeth 251 of the sliding strip 25 are clamped in the steel bar, the connection strength of the connecting assembly 1 to the steel bar is improved, preventing the steel bar from detaching, thereby improving the seismic performance of the building.
