Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a primary and secondary beam connection structure of an assembled building and a construction process. Background Art

[0002] The connection between main and secondary beams is a structural connection method for a building. The rigidity and stability of the beam are crucial to the safety and stability of the building. By connecting the main beam with the beam, the overall structure can be made more stable and meet the use requirements of the building.

[0003] When installing the existing main and secondary beam connection structure, it is necessary to transport a variety of prefabricated parts to the construction site, and then the workers connect the prefabricated parts to the main beam or secondary beam by welding or other means, and then connect the main beam to the secondary beam, which is time-consuming and labor-intensive. In addition, when the prefabricated parts need to be dismantled, they can only be dismantled by force. When they need to be used again, they must be processed again by grinding and polishing to ensure the connection performance of the prefabricated parts. The efficiency is low. There is a slight height difference between the main and secondary beams, which results in the need to use a crowbar to continuously pry the secondary beam to adjust the position when installing bolts, or to expand the bolt holes of the secondary beam, which is extremely inconvenient.

[0025] like Figure 6 , Figure 8-Figure 10 As shown, the reinforcement mechanism also includes an E-shaped frame 701, the right side of the right connecting plate C207 is slidably connected to the E-shaped frame 701, the left side of the E-shaped frame 701 is symmetrically provided with two groups of inclined grooves, each group is two, the right side of the right connecting plate C207 is symmetrically provided with two groups of arc blocks 702, each group is two, and when the two arc blocks 702 are fitted together, a complete circular ring can be formed, a sliding shaft is fixedly connected to the right side of the arc block 702, the sliding shaft is inserted into the corresponding inclined groove and slides therein, the outer walls of the two locking pins A208 on the front side are provided with annular grooves for use with the arc blocks 702, the left side of the E-shaped frame 701 is through-inserted with a locking pin D703, the front side of the right connecting plate C207 is fixedly connected to a limiting plate, and the limiting plate is provided with a through hole C for use with the locking pin D703.

[0026] like Figure 6As shown, the reinforcement mechanism also includes a gear A704, a gear A704 is fixedly connected to the right side of the slide rod 601, an L-shaped plate 705 is symmetrically fixedly connected to the right side of the right connecting plate C207, two locking pins A208 on the front side are slidably connected with the corresponding L-shaped plates 705, and the right side of the L-shaped plate 705 is rotatably connected with a gear B706 meshing with the gear A704, and the inner wall of the gear B706 is symmetrically fixed with protrusions, and one end of the two locking pins A208 on the front side is symmetrically provided with rectangular grooves used in conjunction with the protrusions.

[0027] like Figure 8-Figure 10 As shown, the reinforcement mechanism also includes a protruding block 801, and the protruding block 801 is fixedly connected to the left side of the arc block 702. The inner walls of the annular grooves of the two front locking pins A208 are symmetrically fixed with arc plates 802 used in conjunction with the protruding block 801. The sides of the two adjacent protruding blocks 801 that are close to each other are gradually curved, and the radii of the arc surfaces of the protruding blocks 801 at both ends continuously increase toward the middle. The radius of the arc surface of the protruding block 801 in the middle is greater than the radius of the inner arc surface of the arc plate 802.

[0028] Initially, the elastic member A is in a released state, the rectangular frame 202 can slide horizontally in the rectangular frame 201, the elastic wedge block A303 is inserted into the slot of the corresponding slider 304, and the two connecting plates A205 are perpendicular to the fixed plate 204. The secondary beam 101 is first hoisted to the top of the two adjacent main beams 1 by the hoisting equipment in the prior art, and then the rectangular frame 202 is pushed by the staff to slide in the rectangular frame 201. The rectangular frame 202 drives the fixed plate 204 to slide in the rectangular frame 201, so that the fixed plate 204 and the web of the secondary beam 101 are in the same vertical plane, and then the secondary beam 101 is placed on the supporting plate 203. The supporting plate 203 slides down under the influence of the weight of the secondary beam 101, and the elastic member A is contracted by force. The supporting plate 203 drives the two elastic wedge blocks A303 to descend through the sliding frame 302, and drives the locking pin B301 to descend. The elastic wedge block A303 presses the adjacent sliders 304. The slot is squeezed, so that the slider 304 drives the corresponding sleeve 305 to drop through the vertical axis thereon, and the elastic member C is extended by force, and the sleeve 305 drives the guide block therein to squeeze the spiral groove of the adjacent guide column 306. The spiral groove is forced to drive the corresponding guide column 306 to rotate, and the guide column 306 drives the connecting plate A205 to rotate with the connection point of the corresponding sliding shaft as the center of the circle. At this time, the two connecting plates A205 rotate close to each other, and the connecting plate A205 drives the corresponding connecting plate C207 to rotate, and then the two connecting plates A205 are respectively fitted with the two sides of the fixed plate 204, and the two connecting plates C207 connected by the two connecting plates A205 are fitted with the two sides of the web of the secondary beam 101. After the locking pin B301 drops, it is inserted into the corresponding locking hole at the bottom of the inner wall of the rectangular frame 201, and the locking pin B301 limits the rectangular frame 202, so that the fixed plate 204 and the connecting plate A205 no longer move, thereby preventing the secondary beam 101 from displacement.

[0029] Initially, the elastic member D is in a released state, the top surfaces of the connecting plates A401 and B402 are in the same horizontal plane, the elastic member E is in a released state, and the two sets of locking pins A208 are respectively inserted into the through holes A of the left connecting plate B206 and the connecting plate C207. Due to the height difference between the two adjacent main beams 1, when installing the secondary beam 101, the secondary beam 101 will be slightly tilted due to the height difference between the two main beams 1, resulting in the two insertion holes of the secondary beam 101 being misaligned with the two locking pins A208 on the connecting plate B402. At this time, the staff will first push the two connecting plates B206 to make the two connecting plates B206 slide close to each other in the rectangular frame 201 until the two connecting plates B206 are respectively connected to the adjacent connecting plates. The side of connecting plate A205 is fitted, and then the staff pushes connecting plate B402 through the handle on one side of connecting plate B402. The connecting plate B402 is forced to drive connecting plate A401 to slide horizontally to the right, and the elastic member E is forced to shrink. Connecting plate A401 drives locking block A501 and the corresponding two locking pins A208 to move to the right, and connecting plate B402 drives the corresponding two locking pins A208 to move to the right, so that the two groups of locking pins A208 pass through the two through holes A of the connecting plate A205 and the connecting plate C207 on the left side of the fixed plate 204 respectively. Since the two sockets of the secondary beam 101 are misaligned with the two locking pins A208 on the connecting plate B402, the two locking pins A208 on the connecting plate B402 are in contact with the edges of the two sockets of the secondary beam 101 at this time, and the front side The two locking pins A208 are blocked and cannot move. At this time, the staff drives the connecting plate B402 to rotate upward or downward with the connection point of the connecting plate A401 as the center through the handle on one side of the connecting plate B402 according to the misaligned direction of the two insertion holes of the secondary beam 101. The elastic part D is forced to shrink, and the connecting plate B402 drives the corresponding two locking pins A208 to rotate. The through holes A of the two connecting plates C207 on the left are squeezed by the two locking pins A208, so that the two connecting plates C207 on the left are respectively rotated with the connection point of the corresponding connecting plate A205 and the connecting plate B206 as the center, and the elastic parts B corresponding to the two connecting plates C207 on the left are forced to shrink until the two locking pins A208 on the connecting plate B402 are aligned with the two insertion holes of the secondary beam 101, and the engagement is completed. The connecting plate A401 and the connecting plate B402 move again, and the connecting plate A401 drives the locking block A501 and the two locking pins A208 thereon to move, and the two locking pins A208 on the connecting plate B402 move, so that the two groups of locking pins A208 are respectively inserted into the two through holes A of the fixed plate 204 and the two plug holes of the secondary beam 101, and the staff rotates the two connecting plates C207 on the right side at the same time, and the two connecting plates C207 on the right side respectively rotate with the connection point of the corresponding connecting plate A205 and the connecting plate B206 as the center of the circle, and the elastic parts B corresponding to the two connecting plates C207 on the right side are contracted by force, so that the through hole A of the connecting plate C207 on the right side is aligned with the corresponding locking pin A208, so that the two groups of locking pins A208 can continue to move to the right,The two lock pins A208 corresponding to the connecting plate B402 pass through the through holes A of the corresponding connecting plate C207 respectively, and the protrusions in the two gears B706 are respectively inserted into the rectangular grooves of the corresponding lock pins A208. Then the staff inserts the lock pin C502 into the through hole B of the lock block A501. The lock pin C502 limits the connecting plate A401 through the lock block A501, so that the connecting plate A401 and the connecting plate B402 respectively drive the corresponding two lock pins A208 to remain stable.

[0030] Initially, there is a gap between the two adjacent arc blocks 702, and the locking pin D703 is not inserted into the through hole C of the upper limit plate of the right connecting plate C207. The staff first slides the sliding rod 601 horizontally to the front side, and the elastic member F is extended by force. The sliding rod 601 drives the locking block B602 and the gear A704 to move. After the gear A704 moves, it meshes with the two gears B706. After the locking block B602 moves, it squeezes the wedge surface of the elastic wedge block B604. The elastic wedge block B604 is forced to shrink until the locking block B602 passes over the wedge surface of the elastic wedge block B604. The elastic wedge block B604 releases and slides back, and contacts the vertical surface of the locking block B602, so that the sliding rod 601 is limited by the locking block B602, so that the elastic member F remains in the extended state, and the gear A704 remains meshed with the two gears B706. The E-shaped frame 701 is then pushed horizontally to the rear by the staff. The E-shaped frame 701 squeezes the sliding axes of the four arc blocks 702 through the two sets of inclined grooves therein, so that the two adjacent arc blocks 702 slide close to each other, and the arc blocks 702 drive the corresponding protruding blocks 801 to move. After sliding, the two adjacent arc blocks 702 are stuck in the annular grooves of the corresponding locking pins A208 and merged into a complete circular ring, so that the protruding blocks 801 contact the outer walls of the annular grooves of the corresponding locking pins A208, and the outer arc edge of the protruding block 801 is misaligned with the inner arc surfaces of the two adjacent arc plates 802. At this time, the locking pin D703 is aligned with the through hole C of the upper limit plate of the connecting plate C207. The staff inserts the locking pin D703 into the through hole C to limit the E-shaped frame 701, thereby completing the assembly of the connection structure of the main beam 1 and the secondary beam 101.

[0031] When the main beam 1 sinks due to natural or other factors, resulting in an increase in the height difference between two adjacent main beams 1, the secondary beam 101 will produce a slight twist, and the secondary beam 101 drives the corresponding two locking pins A208 to move through the two sockets therein, and the two locking pins A208 on the front side drive the four connecting plates C207 to rotate around the connection between the two connecting plates A205 and the two connecting plates B206 as the center of the circle, and the elastic member B is contracted or released under force, and the connecting plate C207 on the right side drives the two gears B706 to move through the two L-shaped plates 705. The two gears B706 move at the connection between the L-shaped plates 705 under the action of the gear A704. The locking pin A208 rotates around the connection point of the connecting plate B402 as the center of the circle, and squeezes the rectangular groove of the adjacent locking pin A208 through the protrusion inside it, so that the locking pin A208 rotates around the connection point of the connecting plate B402 as the center of the circle. At the same time, the locking pin A208 drives the two arc plates 802 inside it to rotate. After the arc plates 802 rotate, they contact and squeeze the adjacent protruding blocks 801. Due to the arc surface characteristics of the protruding blocks 801, the friction between the arc plates 802 and the protruding blocks 801 is increased through the squeezing of the arc plates 802 and the adjacent protruding blocks 801, thereby preventing the arc blocks 702 from being separated from the annular grooves of the corresponding locking pins A208, and further improving the firmness between the main beam 1 and the secondary beam 101. Example 2

[0032] like Fig.11 As shown, it also includes a guide plate 901, the bottom of the supporting plate 203 is fixedly connected with the guide plate 901, a pull rod 902 is slidably connected through the guide plate 901, the pull rod 902 is fixedly connected to the sliding frame 302, and an elastic member G is provided between the sliding frame 302 and the guide plate 901, and the elastic member G is a compression spring.

[0033] When the secondary beam 101 needs to be removed, the staff first pulls out the locking pin D703 from the through hole C of the upper limit plate of the right connecting plate C207 to enable the E-shaped frame 701 to move, and then pulls the E-shaped frame 701 to the front side. The E-shaped frame 701 squeezes the sliding shafts of the two sets of arc blocks 702 through the two sets of inclined grooves therein, so that the two adjacent arc blocks 702 slide away from each other and reset. The arc block 702 drives the protruding block 801 therein to move and reset, and then pushes the pressing block 605 downward. The pressing block 605 is subjected to force to drive the elastic wedge block B604 to shrink and slide through the connecting shaft. After sliding, the elastic wedge block B604 no longer contacts the locking block B602. After the locking block B602 is freed from the restriction, the sliding rod 601 can move, and the elastic member F shrinks and drives the sliding rod 601 slides to reset, the slide bar 601 drives the gear A704 away from the two gears B706, and then the staff lifts the lock pin C502 upward to disengage the lock pin C502 from the through hole B of the lock block A501. After the lock block A501 is freed from the restriction, the connecting plate A401 can move, and the elastic member E is released to drive the connecting plate A401 to move and reset, and the connecting plate A401 drives the connecting plate B402 to move and reset, and the connecting plate A401 and the connecting plate B402 respectively drive the corresponding two lock pins A208 to move and reset, so that the two groups of lock pins A208 are respectively disengaged from the through holes A of the fixed plate 204, the two connecting plates A205, the two connecting plates B206 and the four connecting plates C207, and are disengaged from the two sockets of the secondary beam 101, and then the staff The personnel push the two connecting plates B206 away from each other to reset them, so that the two connecting plates B206 are respectively away from the adjacent connecting plates A205, and then pull the pull rod 902 to the front side, and the pull rod 902 drives the sliding frame 302 to slide to the front side, and the elastic member G is forced to shrink, and the sliding frame 302 drives the two elastic wedge blocks A303 therein to move to the front side. After the elastic wedge blocks A303 move, they disengage from the corresponding slots of the sliders 304. After the sliders 304 are freed from the restrictions, the elastic member C shrinks and drives the sliders 304 to slide and reset. The sliders 304 drive the corresponding sleeves 305 to lift and reset upwards through the vertical axis. The sleeves 305 squeeze the spiral grooves of the guide posts 306 through the guide blocks therein. The guide posts 306 are forced to drive the corresponding connecting plates A205 to rotate and reset. The connecting plate A205 drives the corresponding connecting plate C207 to rotate and reset. After the connecting plate C207 rotates and resets, it no longer contacts the secondary beam 101. Then the pull rod 902 is loosened, and the elastic member G is released to drive the sliding frame 302 to slide and reset. The sliding frame 302 drives the pull rod 902 to move and reset. Then the secondary beam 101 is lifted by the lifting equipment, so that the secondary beam 101 can be separated from the main beam 1. After the secondary beam 101 is lifted, it no longer squeezes the supporting plate 203. The elastic member A is released to drive the supporting plate 203 to reset. The supporting plate 203 drives the locking pin B301 and the sliding frame 302 to lift and reset upward. In this process, the sliding frame 302 drives the two elastic wedge blocks A303 to lift. After the elastic wedge blocks A303 are lifted, they contact and squeeze the corresponding sliders 304.Since the elastic force of the elastic member A is greater than the elastic force of the elastic wedge block A303, the elastic wedge block A303 is forced to shrink and slide until the elastic wedge block A303 is aligned with the corresponding slot of the slider 304, and the elastic wedge block A303 is released and inserted into the slot of the slider 304, thereby completing the installation and reset of the overall connection structure.

[0034] A construction process for a prefabricated building main and secondary beam connection structure comprises the following steps: S1: The staff pushes the rectangular frame 202 to slide in the rectangular frame 201, so that the fixed plate 204 and the web of the secondary beam 101 are on the same vertical plane, and the secondary beam 101 is placed on the supporting plate 203, so that the connecting plate A205 drives the connecting plate C207 to rotate and fit with both sides of the fixed plate 204 and both sides of the web of the secondary beam 101; S2: Push the connecting plate B402 through the handle on one side of the connecting plate B402, and drive the connecting plate B402 to rotate, so that the other set of locking pins A208 are aligned with the two insertion holes of the secondary beam 101; S3: Slide the slide bar 601 horizontally to the front side, so that the gear A704 is meshed with the gear B706, and the elastic wedge block B604 limits the lock block B602, so that the gear A704 remains meshed with the gear B706, and the E-shaped frame 701 is pushed horizontally to the rear side, so that the two adjacent arc blocks 702 are stuck in the annular grooves of the corresponding lock pins A208; S4: When the secondary beam 101 is slightly twisted, the arc-shaped plate 802 is squeezed by the adjacent protruding block 801 to improve the firmness between the main beam 1 and the secondary beam 101.
