Prefabricated buildings are usually composed of prefabricated concrete prefabricated components of various shapes. The production of prefabricated components and the installation on the construction site are both streamlined and reproducible labor processes, which facilitates construction.

[0003] During the production of the prefabricated balcony slabs in the prior art, the steel trusses are first placed in the forming mold and then poured.

The outer wall of the cross bar is symmetrically fixed with pins 304, and one end of the first connecting rod 302 is rotatably connected to the outer wall of the cross bar of the guide frame 303. A plug-in plate 305 is installed on the top of the three first rectangular grooves of the scraper 201, and two groups of plug-in holes used in conjunction with the plug-in pins 304 are symmetrically opened at the bottom of the plug-in plate 305, and each group has two.

[0036] like Figure 5 and Figure 6 As shown, the anti-misalignment mechanism includes an L-shaped rod 401, the top front side of the I-shaped plate 203 is fixedly connected with the L-shaped rod 401, the front end of the L-shaped rod 401 is fixedly connected with a first guide rail 402, a triangular block 403 is slidably connected in the first guide rail 402, a second guide rail 404 is symmetrically fixedly connected to the front side of the floating frame 202, a sliding rod 405 is vertically slidably connected in the two second guide rails 404, the triangular block 403 is used in conjunction with the sliding rod 405, a first elastic member is arranged between the sliding rod 405 and the second guide rail 404, and the first elastic member is a compression spring.

[0037] like Figure 6 and Figure 7 As shown, the anti-misalignment mechanism also includes a second connecting rod 501, and the outer wall of the sliding rod 405 is symmetrically fixed with the second connecting rod 501, and a rotating frame 502 is hinged between the two second guide rails 404, and a second elastic member is arranged between the rotating frame 502 and the second guide rail 404, and the second elastic member is a torsion spring. A protruding shaft is fixed to the bottom of the side where the two second connecting rods 501 are close to each other, and the protruding shaft is stuck in the rotating frame 502 and slides therein. When the second connecting rod 501 falls downward, the rotating frame 502 can be rotated by the protruding shaft, and a horizontal plate 503 is slidably connected in the rotating frame 502, and a third elastic member is arranged between the horizontal plate 503 and the rotating frame 502, and the third elastic member is a tension spring.

[0038] like Figure 7 As shown, the anti-misalignment mechanism also includes a fourth elastic wedge block 504, and second rectangular grooves are symmetrically opened on both sides of the cross plate 503. The fourth elastic wedge block 504 is slidably connected in the second rectangular groove. The fourth elastic wedge block 504 is used in conjunction with the protruding shaft of the second connecting rod 501. When the protruding shaft of the second connecting rod 501 squeezes the fourth elastic wedge block 504, the cross plate 503 can slide.

[0039] like Figure 8 and Fig. 9As shown, a vibrating mechanism is also included, which includes a sliding plate 601. The sliding plate 601 is horizontally slidably connected in the floating frame 202. A fourth elastic member is rotatably connected between the sliding plate 601 and the I-shaped plate 203. The fourth elastic member is a tension spring. Damping strips are embedded and fixedly connected on both sides of the sliding plate 601. The damping strips can prevent the sliding plate 601 from sliding too fast. A first wave groove is provided at the bottom of the sliding plate 601. A sliding shaft 602 is slidably connected in the first wave groove. When the sliding plate 601 slides, the sliding shaft 602 can move horizontally back and forth. A vibrating rod 604 is provided on the lower side of the sliding plate 601. The vibrating rod 604 is electrically connected to the pin 304. The top of the vibrating rod 604 is fixedly connected to a telescopic shaft 603. The telescopic end of the telescopic shaft 603 is hinged to the bottom end of the sliding shaft 602.

[0040] like Figure 8 and Fig. 9 As shown, the vibrating mechanism also includes an arc-shaped shell 605. The bottom of the floating frame 202 is fixedly connected with the arc-shaped shell 605. The outer wall of the arc-shaped shell 605 is provided with a through groove. One end of the vibrating rod 604 penetrates the through groove of the arc-shaped shell 605. The outer wall of the vibrating rod 604 is fixedly sleeved with a blocking plate 606. The blocking plate 606 is slidably connected to the inner wall of the arc-shaped shell 605. The blocking plate 606 is used to prevent concrete from entering the arc-shaped shell 605.

[0041] Initially, the front pin 304 is inserted into the two plug holes on the front side of the corresponding plug plate 305, and the limit pin 2021 is inserted into the limit hole of the corresponding floating frame 202. First, concrete is injected into the forming mold 101 through the pouring equipment in the prior art. After the concrete pouring is completed, the gantry 1 is started, and the gantry 1 drives the scraper 201 to move forward, and drives the three plug plates 305 to move forward. The scraper 201 drives the three limit pins 2021 thereon to drive the three floating frames 202 to move forward. Then the gantry 1 drives the scraper 201 to descend, and then the three floating frames 202, the three limit pins 2021 and the three plug plates 305 descend downward until the scraper 201 and the bottom of the three floating frames 202 contact the surface of the concrete, and then the staff pulls the three limit pins 2021 to one side to disengage the limit pins 2021 from the limit holes of the corresponding floating frames 202. It is worth noting It is worth noting that the density of concrete is relatively large. After the floating frame 202 is freed from the restriction, the concrete can provide buoyancy to the floating frame 202, and the floating frame 202 will not sink, and the bottom surface of the floating frame 202 and the bottom surface of the scraper 201 are always in the same horizontal plane. Then the gantry 1 is controlled to move forward, so that the scraper 201 drives the three plug-in plates 305 to move. The plug-in plates 305 squeeze the outer wall of the front pins 304 through the plug-in holes therein, and the pins 304 are forced to squeeze the inner wall of the guide frame 303 through the cross bar. The guide frame 303 is forced to drive the corresponding floating frame 202 to move horizontally to the front side, and at the same time, the vibrating rod 604 is started to make the vibrating rod 604 vibrate the concrete in the truss 102. It is worth noting that the three floating frames 202 are respectively located on the vertical center lines of the three trusses 102, and the scraper 201 and the floating frame 202 can scrape the concrete surface during the horizontal movement.

[0042] Initially, the first elastic wedge block 204 is in an extended state, and the second elastic wedge block 205 is in a contracted state. Taking one of the floating frames 202 as an example, when the floating frame 202 moves horizontally, it drives the two first elastic wedge blocks 204 and the two second elastic wedge blocks 205 therein to move horizontally. Then, the wedge surfaces of the two first elastic wedge blocks 204 contact the outer wall of the truss 102, and the truss 102 squeezes the first elastic wedge blocks 204. The two adjacent first elastic wedge blocks 204 are forced to slide close to each other and squeeze the I-shaped plate 203. The I-shaped plate 203 is forced to move along the belt of the floating frame 202. The movable installation box 206 moves slowly horizontally to the rear side, and the installation box 206 drives the two connecting rods 301 to move. The front connecting rod 301 applies a pulling force to the cross bar in the front guide frame 303 through the first connecting rod 302, and the cross bar is forced to drive the pin 304 to fall downward along the corresponding guide frame 303. The rear connecting rod 301 applies a thrust to the cross bar in the rear guide frame 303 through the first connecting rod 302, and the cross bar is forced to drive the pin 304 to rise upward along the corresponding guide frame 303. At the same time, the installation box 206 drives the corresponding two third elastic wedge blocks 207 to move to the rear side. The two third elastic wedge blocks 207 The rear side inclined surfaces of the wedge blocks 207 are squeezed and slid by the outer walls of the corresponding V-shaped plates 208, and then the vertical surfaces of the two third elastic wedge blocks 207 contact the outer walls of the corresponding V-shaped plates 208. At this time, the two third elastic wedge blocks 207 continue to move backward until the front side inclined surfaces of the third elastic wedge blocks 207 contact the rear side inclined surfaces of the corresponding V-shaped plates 208. The two adjacent third elastic wedge blocks 207 are quickly released and slid back, and drive the installation box 206 to slide rapidly backward through the cooperation with the V-shaped plate 208, and the installation box 206 drives the I-shaped plate 203 and the two connecting rods 301 to move rapidly backward The I-shaped plate 203 slides sideways, causing the front pin 304 to drop rapidly, while the rear pin 304 rises rapidly and is inserted into the rear plug-in hole of the corresponding plug-in board 305. By causing the front pin 304 to drop rapidly, the front pin 304 can be prevented from contacting the truss 102 and causing damage to the pin 304. When the I-shaped plate 203 slides rapidly toward the rear, the wedge surfaces of the two adjacent second elastic wedge blocks 205 are squeezed and no longer contact the two first elastic wedge blocks 204. The two first elastic wedge blocks 204 shrink rapidly and slide back to their original position, and the two second elastic wedge blocks 205 are forced to extend and slide rapidly away from each other.

[0043] When the I-shaped plate 203 slides slowly backward, the I-shaped plate 203 drives the first guide rail 402 to slide slowly backward through the L-shaped rod 401, and the first guide rail 402 drives the triangular block 403 to move backward. When the triangular block 403 moves, it squeezes the outer wall of the sliding rod 405. The sliding rod 405 is forced to fall downward along the two second guide rails 404. The first elastic member is forced to shrink, and the sliding rod 405 drives the two second connecting rods 501 to fall downward. The second connecting rod 501 squeezes the inner wall of the rotating frame 502 through the protruding shaft thereon. The rotating frame 502 is forced to drive the cross plate 503 to rotate slowly downward with the connection point of the second guide rails 404 as the center of the circle. The second elastic member is forced to shrink slowly. When the I-shaped plate 203 slides rapidly backward, the triangular block 403 is pushed backward. The rear side moves rapidly, and the sliding rod 405 drops rapidly downward under the action of the triangular block 403. The first elastic member contracts rapidly, thereby causing the second connecting rod 501 to drive the protruding shaft to drop rapidly. The cross plate 503 is squeezed by the protruding shaft and rotates rapidly downward. The second elastic member contracts rapidly under force. In the process of the rapid drop of the protruding shaft, the protruding shaft contacts and squeezes the outer wall of the corresponding fourth elastic wedge block 504. The fourth elastic wedge block 504 contracts under force. The cross plate 503 rotates rapidly and then inserts into the concrete, and applies a backward thrust to the concrete. The concrete applies a forward reaction force to the cross plate 503. The cross plate 503 is forced to apply a forward force to the floating frame 202 through the rotating frame 502 and the second guide rail 404. When the I-shaped plate 203 slides rapidly to the rear side, the I-shaped plate 203 will apply a backward thrust to the floating frame 202. The above steps can offset the backward thrust of the I-shaped plate 203, thereby preventing the rear side plug pin 304 from being unable to be inserted into the rear side plug hole of the corresponding plug board 305 when moving upward. Then the triangular block 403 passes over the sliding rod 405, and the first elastic member is released to drive the sliding rod 405 to slide and lift. The sliding rod 405 drives the two second connecting rods 501 to lift upward, and the second connecting rod 501 drives the protruding shaft thereon to squeeze the adjacent fourth elastic wedge block 504. It is worth noting that the elastic force of the fourth elastic wedge block 504 is greater than the elastic force of the third elastic member. After being squeezed, the two fourth elastic wedge blocks 504 jointly drive the cross plate 503 to lift upward, and the third elastic member is forced to shrink. After the cross plate 503 is lifted No longer in contact with concrete, the third elastic member then contracts to its limit, and the sliding rod 405 continues to lift upward, so that the protruding shaft of the second connecting rod 501 continues to squeeze the adjacent fourth elastic wedge block 504. The fourth elastic wedge block 504 contracts and slides under the force, and then the protruding shaft passes over the fourth elastic wedge block 504 and no longer in contact with the fourth elastic wedge block 504. The fourth elastic wedge block 504 is released to slide and reset, and the sliding rod 405 continues to slide upward and reset. The third elastic member is released to drive the cross plate 503 to slide and reset. At the same time, the second elastic member is released and drives the cross plate 503 to rotate and reset through the rotating frame 502. Since the cross plate 503 is far away from the concrete at this time, the cross plate 503 will not be affected by the concrete when it rotates and resets, thereby affecting the activity of the floating frame 202.

[0044] Then, the wedge surface of the second elastic wedge block 205 contacts the outer wall of the truss 102, and the truss 102 squeezes the second elastic wedge block 205. The two adjacent second elastic wedge blocks 205 slide close to each other under the force and squeeze the I-shaped plate 203. The I-shaped plate 203 drives the installation box 206 to move slowly to the front side. The installation box 206 drives the two connecting rods 301 to move. The front connecting rod 301 applies a thrust to the cross bar in the front guide frame 303 through the first connecting rod 302. The cross bar drives the pin 304 under the force. The corresponding guide frame 303 is lifted upward, and the rear connecting rod 301 applies a pulling force to the cross bar in the rear guide frame 303 through the first connecting rod 302. The cross bar is forced to drive the pin 304 to fall downward along the corresponding guide frame 303. At the same time, the installation box 206 drives the corresponding two third elastic wedge blocks 207 to move forward. The front side inclined surfaces of the two third elastic wedge blocks 207 are squeezed and contracted by the outer wall of the corresponding V-shaped plate 208 to slide. Then, the vertical surfaces of the two third elastic wedge blocks 207 and the corresponding V-shaped plate The outer wall of the V-shaped plate 208 is contacted by the two third elastic wedge blocks 207. At this time, the two third elastic wedge blocks 207 continue to move forward until the rear side slope of the third elastic wedge block 207 contacts the front side slope of the corresponding V-shaped plate 208. The two adjacent third elastic wedge blocks 207 are quickly released to slide back and drive the installation box 206 to slide rapidly forward through the cooperation with the V-shaped plate 208. The installation box 206 drives the I-shaped plate 203 and the two connecting rods 301 to slide rapidly forward, thereby causing the pin 304 on the rear side to drop rapidly, and the pin 304 on the front side to 4 is lifted up rapidly and inserted into the front plug hole of the corresponding plug board 305. By making the plug pin 304 on the rear side fall rapidly, it can prevent the plug pin 304 on the rear side from contacting with the truss 102 and causing damage to the plug pin 304. When the I-shaped plate 203 slides rapidly toward the front side, it squeezes the wedge surfaces of the two adjacent first elastic wedge blocks 204 and no longer contacts with the two second elastic wedge blocks 205. The two second elastic wedge blocks 205 shrink rapidly and slide back to their original positions. The two first elastic wedge blocks 204 are forced to extend and slide rapidly away from each other.

[0045] When the I-shaped plate 203 slides slowly toward the front side, the I-shaped plate 203 drives the first guide rail 402 to slide slowly toward the front side through the L-shaped rod 401, and the first guide rail 402 drives the triangular block 403 to move toward the front side. When the triangular block 403 moves, it is squeezed by the outer wall of the sliding rod 405 and slides obliquely upward along the first guide rail 402 until the bottom of the triangular block 403 and the top of the outer wall of the sliding rod 405 are in the same horizontal plane. The first guide rail 402 applies a thrust to the triangular block 403, causing the triangular block 403 to slide toward the front side and slide obliquely downward along the first guide rail 402 to reset. When the I-shaped plate 203 slides rapidly toward the front side, the I-shaped plate 203 applies a forward thrust to the floating frame 202. It is worth noting that due to the high density of concrete, when the pin 304 on the rear side is disengaged from the corresponding plug hole on the rear side of the plug plate 305, The floating frame 202 will lose its forward force, and the scraper 201 and the three plug-in plates 305 are still moving forward, resulting in a slight misalignment between the floating frame 202 and the corresponding plug-in plates 305. When the floating frame 202 is subjected to the forward thrust, the floating frame 202 can only move forward a short distance due to the influence of the concrete. After the floating frame 202 moves forward, it can make up for the slight misalignment with the corresponding plug-in plates 305, so that the front side plug pins 304 can still be inserted into the plug-in holes on the front side of the corresponding plug-in plates 305 after being lifted upward. As the floating frame 202 continues to move, the first elastic wedge block 204 and the second elastic wedge block 205 contact the truss 102, and repeat the above steps to achieve the same effect, thereby the concrete surface in the truss 102 can be scraped by the floating frame 202, which greatly improves the work efficiency.

[0046] When the I-shaped plate 203 slides slowly backward, the I-shaped plate 203 applies a pulling force to the sliding plate 601 through the fourth elastic member. The sliding plate 601 is forced to drive the two damping strips thereon to slide slowly backward. At this time, the two damping strips will not generate resistance to the sliding plate 601. When the sliding plate 601 slides, the first wave groove at its bottom squeezes the outer wall of the sliding shaft 602. The sliding shaft 602 is forced to reciprocate horizontally along the first wave groove, and drives the vibrating rod 604 to swing back and forth through the telescopic shaft 603. In this process, the telescopic end of the telescopic shaft 603 is continuously extended and retracted, and the vibrating rod 604 drives the blocking plate 606 to slide back and forth along the inner wall of the arc shell 605. ... When the I-shaped plate 203 slides rapidly toward the rear side, the pulling force applied by the I-shaped plate 203 to the sliding plate 601 through the fourth elastic member increases, and the two damping strips can apply resistance to the sliding plate 601 by rubbing against the inner wall of the floating frame 202, so that the sliding plate 601 keeps sliding slowly, and then the vibrating rod 604 keeps swinging back and forth at a uniform speed, thereby preventing the vibrating rod 604 from swinging too fast, causing bubbles to be generated inside the concrete. When the I-shaped plate 203 slides slowly toward the front side, the vibrating rod 604 repeats the above steps to swing. When the I-shaped plate 203 slides rapidly toward the front side, the two damping strips can achieve the same effect as the above steps by rubbing against the inner wall of the floating frame 202.

[0051] Initially, the fifth elastic member, the sixth elastic member, the seventh elastic member and the eighth elastic member are all in a released state, and the telescopic end of the elastic telescopic rod 704 is stuck in the trapezoidal groove of the corresponding sliding rod 703. As the scraper 201 moves forward, the scraper 201 drives the rotating roller 702 and the fitting frame 801 to contact the outer wall of the pipe mold 100 through the sliding frame 701 and the sliding rod 703. The two rotating rollers 702 are squeezed by the outer wall of the pipe mold 100, driving the two sliding frames 701 to slide away from each other. The fifth elastic member is forced to shrink, and at the same time, the sliding frame 701 drives the corresponding elastic telescopic rod 704 to move horizontally. The telescopic end of the elastic telescopic rod 704 squeezes the inner wall of the trapezoidal groove of the adjacent sliding rod 703, causing the two sliding rods 703 to slide away from each other. The force contracts, the sliding rod 703 drives the corresponding fitting frame 801 to move horizontally, the fitting frame 801 drives the movable rod 802 therein to move horizontally, the movable rod 802 drives the several cleaning blocks 803 thereon and the guide block 901 to move horizontally, the guide block 901 drives the convex shaft thereon to slide along the corresponding second wave groove in the scraper 201, and the convex shaft drives the several cleaning blocks 803 to move vertically back and forth through the guide block 901 and the movable rod 802. When dry concrete remains on the outer wall of the pipeline mold 100, the dry concrete remaining on the outer wall of part of the pipeline mold 100 can be scraped off by the vertical reciprocating movement of the several cleaning blocks 803. At this time, the two fitting frames 801 remain in contact with the outer wall of the pipeline mold 100, and the pipeline mold 100 is close to the fitting frames 801. 1, the laminating frame 801 is forced to rotate with the connection point of the corresponding sliding rod 703 as the center of the circle, and the seventh elastic member is forced to shrink. When the two rotating rollers 702 pass the center of the circle of the pipeline mold 100, the fifth elastic member is gradually released and drives the rotating roller 702 to move and reset through the sliding frame 701. At the same time, the sliding frame 701 drives the corresponding elastic telescopic rod 704 to move and reset. The telescopic end of the elastic telescopic rod 704 slides and shrinks along the trapezoidal groove of the corresponding sliding rod 703. Then the telescopic end of the elastic telescopic rod 704 passes the trapezoidal groove and contacts the outer wall of the sliding rod 703. The telescopic end of the elastic telescopic rod 704 remains in a contracted state until the two sliding rods 703 pass the center of the circle of the pipeline mold 100. The sixth elastic member is gradually released and drives the laminating frame 704 to move and reset through the sliding rod 703. The closing frame 801 moves to reset, the laminating frame 801 drives the movable rod 802 to move to reset, the movable rod 802 drives the cleaning blocks 803 thereon and the guide block 901 to move horizontally to reset, and the convex shaft of the guide block 901, under the action of the second wave groove, drives the cleaning blocks 803 to move vertically back and forth again through the guide block 901 and the movable rod 802, thereby scraping off the dry concrete on the remaining outer wall of the pipe mold 100, until the two sliding rods 703 are completely reset, the laminating frame 801 is no longer in contact with the outer wall of the pipe mold 100, the seventh elastic member is released to drive the laminating frame 801 to rotate and reset, the laminating frame 801 drives the cleaning blocks 803 to move and reset through the movable rod 802, and then the inclined surface of the vertical plate 902 contacts the outer wall of the pipe mold 100,The outer wall of the pipe mold 100 squeezes the inclined surface of the vertical plate 902, and the two vertical plates 902 are forced to move away from each other horizontally, and drive the corresponding eighth elastic member to contract until the two vertical plates 902 pass the center of the pipe mold 100. The eighth elastic member is gradually released and drives the vertical plate 902 to reset, thereby scraping the concrete around the pipe mold 100 through the vertical plate 902 to make the concrete surface around the pipe mold 100 smooth. The outer wall of the pipe mold 100 is cleaned by a plurality of cleaning blocks 803, which can prevent the vertical plate 902 from contacting the dry concrete on the outer wall of the pipe mold 100. The vertical plate 902 cannot fit tightly with the outer wall of the pipe mold 100, resulting in the vertical plate 902 being unable to completely contact the concrete surface around the pipe mold 100.

[0052] After completing the scraping work on the concrete, the staff will insert the three limit pins 2021 into the limit holes of the three floating frames 202 respectively, and then control the gantry 1 so that the gantry 1 drives the scraper 201 to lift upward, and the scraper 201 drives the three floating frames 202 to lift upward through the three limit pins 2021, and then control the gantry 1 to drive the scraper 201 to move horizontally and reset, and then make the three floating frames 202 move horizontally and reset, thereby completing the scraping and resetting work of the entire device.
