Figure 1-Figure 13 As shown, an assembled energy-saving and sound-insulating building includes a connecting assembly 1, which is evenly distributed at the lower end of a column 5 or at the lower edge of a wall. The column 5 or the wall is connected to the steel bars on the bottom surface through the connecting assembly 1 to realize the assembly of the wall or the column 5. A grouting port 11 is arranged at the top of the connecting assembly 1, and the grouting port 11 protrudes from the outer surface of the column 5 or the wall. The wall adopts a hollow structure, and the hollow structure can reduce the weight of the wall, reduce the weight and structural size of the building, and at the same time, the hollow structure can achieve sound insulation and heat preservation. See also Figure 2-Figure 4The connection component 1 includes a sleeve 12, and a plurality of fins 123 are evenly distributed on the outer side of the sleeve 12.

A hollow upper sleeve 121 is welded on the upper end of the sleeve 12, and a grouting port 11 is arranged on the top of the upper sleeve 121. After the installation is completed, mud is poured into the connection component 1 through the grouting port 11 to achieve a tight connection between the connection component 1 and the steel bar. A lower sleeve 122 is welded on the lower end of the sleeve 12, and the lower end of the lower sleeve 122 is arranged on the lower bottom surface of the column or wall. An extrusion cylinder 13 is slidably arranged in the lower sleeve 122, and the upper end of the extrusion cylinder 13 is fixedly connected to an upper sliding cylinder 16, and the upper sliding cylinder 16 is slidably arranged in the sleeve 12. A plurality of force-enhancing components 2 are evenly distributed on the upper sliding cylinder 16 in the circumferential direction. The upper sliding cylinder 16 moves upward to drive the force-enhancing component 2 to move, and the steel bar inserted into the upper sliding cylinder 16 is bitten and fixed by the force-enhancing component 2, so as to achieve a tight fixation of the steel bar and the connection component 1. See also Figure 5 and Figure 6 The upper end of the upper sliding cylinder 16 is welded with a support ring 161, and a spring 162 is arranged on the upper end of the support ring 161. The upper end of the spring 162 is connected to the upper retaining ring 1211, and the upper retaining ring 1211 is arranged in the upper sleeve 121. By setting the spring 162, the upper sliding cylinder 16 is kept at the bottom of the sleeve 12 before installation, which facilitates smooth installation.

[0022] For further information, see Figure 3 A guide block 14 is welded at the lower end of the extrusion cylinder 13, a circular guide slope 141 is arranged inside the guide block 14, and a guide inner cylinder 142 is arranged at the upper end of the guide slope 141. The setting of the guide slope 141 and the guide inner cylinder 142 facilitates the smooth entry of the steel bars into the connection component 1, and guides the steel bars, so that the steel bars can enter between the force-enhancing components 2.

[0023] For further information, see Figure 4 , Fig. 9 and Fig.10 , thrust bearings 17 are arranged at the upper and lower ends of the force-increasing component 2, and the outer shell of the thrust bearing 17 is connected to the rotating cylinder 18, and a plurality of extrusion arc blocks 182 are evenly distributed in the circumferential direction of the rotating cylinder 18, and the radial thickness of the extrusion arc blocks 182 gradually increases along the circumferential direction, and a lower baffle plate 181 is welded at the lower end of the rotating cylinder 18, and the upper side surface of the rotating cylinder 18 and the lower side surface of the lower baffle plate 181 are both in contact with 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; The outer side of the rotating cylinder 18 is fixedly sleeved with the driving sleeve 19, and a plurality of driving inclined grooves 191 are evenly distributed on the outer side of the driving sleeve 19. The driving inclined grooves 191 are slidably connected to the sliding column 124, and the sliding column 124 is fixedly arranged on the inner wall of the sleeve 12; through the arrangement of the driving inclined grooves 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 grooves 191. When the rotating cylinder 18 rotates, the force-enhancing component 2 is squeezed by squeezing the arc block 182, so that the force-enhancing component 2 is engaged and fixed to the steel bar.

[0024] For further information, see Figure 7 and Figure 8 The force-increasing assembly 2 includes a rectangular hollow shell 21, two ends of the shell 21 are bolted to the end cover 22, an extrusion block 23 is slidably connected in the shell 21, a limit plate 231 is arranged in the middle of the extrusion block 23, the limit plate 231 abuts against the inner side of the end cover 22, and an end of the extrusion block 23 away from the shell 21 is arranged with an inclined surface 232, and the inclined surface 232 abuts against the surface of the extrusion arc block 182 of the rotating drum 18; Two inclined planes 233 are symmetrically arranged at one end of the extrusion block 23 away from the inclined plane 1 232. The surfaces of the two inclined planes 233 abut against the middle rolling ring 262. The middle rolling ring 262 is rotatably sleeved on the middle part of the roller 26. Both ends of the roller 26 are rotatably sleeved on the end rolling ring 261. A positioning ring is arranged between the end rolling ring 261 and the middle rolling ring 262. The roller 26 slides in the waist-shaped slide groove 211 on the side of the shell 21. The sliding direction of the roller 26 and the sliding direction of the extrusion block 23 are perpendicular to each other.

[0025] When the extrusion block 23 slides, 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 roller 26 and the end rolling ring 261 to slide away from each other in the waist-shaped sliding groove 211 .

[0026] Furthermore, the end rolling ring 261 rolls on the surface of the third inclined plane 242 , and the third inclined plane 242 is symmetrically arranged at one end of the telescopic block 24 close to the extrusion block 23 , and the telescopic block 24 is arranged as a rectangular blind hole, and the blind hole can accommodate the second inclined plane 233 ; A flange is provided on the side of the three inclined surfaces 242 away from each other, and a plurality of second springs 243 are fixedly connected to the side of the flange away from the extrusion block 23, and the other end of the second spring 243 abuts against the end cover 22, and the telescopic block 24 is driven to be in a state of being contracted in the housing 21 by the second spring 243, and the three inclined surfaces 242 of the telescopic block 24 drive the two rollers 26 to be in a state of being close to each other, and the middle rolling ring 262 on the roller 26 squeezes the second inclined surface 233, so that the extrusion block 23 is in a state of being away from the telescopic block 24; The acute angle between the three slopes 242 is greater than the acute angle between the two slopes 233. By setting the angles of the three slopes 242 and the two slopes 233, the movement distance of the extrusion block 23 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 exerted on the pressure block 23, thereby achieving a force-increasing effect and increasing the extrusion pressure of the telescopic block 24 on the steel bars.

[0027] Furthermore, a dovetail groove 241 is provided in the vertical direction at one end of the telescopic block 24 away from the extrusion block 23, a slide bar 25 is provided in the dovetail groove 241 for vertical sliding, and a plurality of latch teeth 251 are evenly distributed in the vertical direction at one side of the slide bar 25 away from the telescopic block 24, and the latch teeth 251 are arranged horizontally; the latch teeth 251 are driven to extend and retract by the telescopic block 24, and the latch teeth 251 are engaged and engaged in the steel bar, thereby realizing a stable engagement connection between the latch teeth 251 and the steel bar, and preventing the steel bar from falling off; The upper and lower ends of the slide bar 25 are both bolted to the 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 .

[0028] Furthermore, the number of the force-increasing assembly 2, the driving inclined groove 191 and the sliding column 124 is three. By providing three force-increasing assemblies 2, the driving inclined groove 191 and the sliding column 124, the force on the steel bar can be uniform, and the structure can be simplified.

[0029] For further information, see Figure 3 and Figure 11-13 The top of the extrusion cylinder 13 is fixedly connected to the top of the lower sliding cylinder 15, and the extrusion cylinder 13 is movably sleeved on the outside of the lower sliding cylinder 15. A limiting shoulder 131 is provided in the middle of the extrusion cylinder 13. The limiting shoulder 131 is used for the lower end of the lower sliding cylinder 15 to abut against the shoulder 131 after the extrusion cylinder 13 is extruded and deformed, so as to achieve axial relative fixation between the extrusion cylinder 13 and the lower sliding cylinder 15; An upper annular groove 135 is arranged on the outer side of the upper end of the extrusion cylinder 13, a lower annular groove 134 is arranged on the lower side of the upper annular groove 135, and an inner annular groove 136 is arranged between the upper annular groove 135 and the lower annular groove 134 on the inner side of the extrusion cylinder 13. The arrangement of the upper annular groove 135, the lower annular groove 134 and the inner annular groove 136 makes it easier for the extrusion cylinder 13 to deform when subjected to an extrusion force. See also 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 bend. 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 separated from the restriction of the lower sleeve 122, and the extrusion cylinder 13 is completely deformed at the positions of the upper annular groove 135, the inner annular groove 136 and the lower annular groove 134 in turn until the limiting shoulder 131 abuts against the lower end of the lower sliding cylinder 15, and the extrusion cylinder 13 is deformed. Fig.13In the above state, the force of the extrusion cylinder 13 is directly transmitted to the lower end of the lower sliding cylinder 15, and the extrusion cylinder 13 is no longer bent 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. After 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.

[0030] For further information, see Fig.11 and Figure 3 The upper end of the extrusion cylinder 13 is evenly distributed with a plurality of vertically arranged through grooves 132 in the circumferential direction, and the lower sliding cylinder 15 is evenly distributed with a plurality of vertically arranged through grooves 151 in the circumferential direction. The through grooves 132 and 151 have the same size and overlap each other in position; The upper sliding cylinder 16 has a plurality of vertically arranged through grooves 3 evenly distributed around the circumference; through the arrangement of through grooves 132, 151 and 153, during grouting, the mud can pass through through grooves 132, 151 and 153 into the sleeve 12, and when the mud solidifies, the positions of the various components in the connecting assembly 1 are fixed.

[0031] Working principle: The column 5 or wall provided with the connection assembly 1 is lifted to the position where installation is required by a tower crane, and the lifted column 5 or wall is placed on the steel bars close to the bottom surface, and the guide block 14 is placed close to the steel bars. By observing the relative position of the guide block 14 and the steel bars, it is determined whether the steel bars and the connection assembly 1 are aligned, thereby improving the convenience of installation; The column 5 or the wall is moved downward, and the steel bar passes through the guide inner cylinder 142 and enters between the slide bars 25 of the force-increasing assembly 2 until the guide block 14 contacts the bottom surface, and then the column 5 or the wall continues to move downward; At this time, the guide block 14 and the steel bar move together into the column 5 or the wall, the guide 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 component 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; The extrusion arc block 182 in the rotating drum 18 squeezes the extrusion block 23, and the inclined surface 232 of the extrusion block 23 drives the two rollers 26 to move away from each other, and the rollers 26 drive the telescopic block 24 and the slide bar 25 to extend, and the slide bar 25 squeezes the steel bar to achieve stable clamping of the steel bar; until the upper side of the rotating drum 18 contacts the inner wall of the upper end of the sleeve 12, at this time, the slide bar 25 stops squeezing the steel bar; Then the column 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, the extrusion cylinder 13 is squeezed 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 5 or the wall contacts the bottom surface, the extrusion cylinder 13 is no longer deformed. Finally, grout is poured into the connection assembly 1 through the grouting port 11, and the grout enters various parts of the connection assembly 1 through the through groove 132, the through groove 2 151 and the through groove 3. When the grout solidifies, the connection assembly 1 is completely fixed. Since the clamping teeth 251 of the slide bar 25 are clamped in the steel bar, the connection strength of the connection assembly 1 to the steel bar is improved, and the steel bar is prevented from being separated, thereby improving the earthquake resistance of the building.
