TECHNICAL FIELD
[0001] The present application relates to the field of construction auxiliary equipment, in particular to a device for assisting in the splicing of prefabricated beams and columns. BACKGROUND
[0002] In prefabricated buildings, prefabricated beams and prefabricated columns are usually pre-fabricated in factories, and then transported to the construction site for assembly. Since the beams and columns have been pre-fabricated in the factory, the pouring time of cast-in-place beams and columns and the solidification time of the beams and columns can be reduced at the construction site. Therefore, the application of prefabricated beams and columns is becoming more and more widespread. With the application of prefabricated beams and columns, how to facilitate the splicing of prefabricated beams and columns has also gradually become a problem to be solved and optimized.
[0003] In the related art, referring to Figure 1 , the end of the prefabricated beam 11 and the end of the prefabricated column 12 are provided with embedded bars. When the prefabricated beam 11 and the prefabricated column 12 are spliced, the embedded bars at the ends of the prefabricated beam 11 and the prefabricated column 12 are inserted into the steel box 14, and then concrete is poured into the steel box 14. After the concrete in the steel box 14 solidifies, the steel box 14 can be fixed with the prefabricated beam 11 and the prefabricated column 12. The splicing scheme of the prefabricated beams and columns is as follows: first, use a crane to hoist the prefabricated column 12 to the pile foundation and fix the prefabricated column 12 with the pile foundation; then, use the crane to hoist the prefabricated beam 11 to the side of the steel box 14, and then assist the prefabricated beam 11 to move and insert into the steel box 14 by personnel.
[0004] In the related art, when the prefabricated beam is butted to the steel box, the accuracy of the crane is not high enough, so personnel assistance is needed to move the prefabricated beam. However, due to the excessive weight of the prefabricated beam, if there is a deviation in the vertical height of the prefabricated beam, it is difficult to position the prefabricated beam at the installation position by personnel assistance. Therefore, it is a problem to be solved to provide a device that can facilitate the insertion and positioning of the prefabricated beam. SUMMARY
[0005] In order to facilitate the insertion and positioning of the prefabricated beam, the present application provides a device for assisting in the splicing of prefabricated beams and columns.
[0006] The device for assisting in the splicing of prefabricated beams and columns provided by the present application adopts the following technical scheme:
[0007] A device for assisting in the splicing of prefabricated beams and columns, comprising a bottom support, a sliding support, an elastic expansion component, and a first limiting component, wherein the elastic expansion component and the first limiting component are located between the bottom support and the sliding support;
[0008] The first limiting component is fixedly connected to the bottom support.
[0009] One end of the elastic telescopic component is fixedly connected to the bottom support, and the sliding support is slidably connected to the other end of the elastic telescopic component, and the sliding direction of the sliding support is perpendicular to the elastic telescopic direction of the elastic telescopic component.
[0010] During the process of gradually increasing the deformation amount of the elastic telescopic component, the sliding support changes from the initial height to the installation height.
[0011] By using the above technical solution, the installation position of the bottom support on the prefabricated column is calculated in advance. If the bottom support is in the installation position, when the prefabricated beam is lapped on the sliding support at the installation height, the prefabricated beam is also at the installation height, and at this time, the sliding direction of the sliding support is parallel to the design direction of the long side of the prefabricated beam, that is, only the sliding support needs to be horizontally pushed along the elastic telescopic component to move the prefabricated beam to the designed position. Therefore, the installation process is as follows: first, fix the bottom support on the prefabricated column and ensure that the prefabricated column is in the installation position; then, use a crane to hoist the prefabricated beam and lap it on the sliding support; the sliding support can change from the initial height to the installation height under the pressure of the prefabricated beam, so that the sliding support is lapped on the first limiting component; finally, push the prefabricated beam to move with the sliding support until the embedded bar is inserted into the steel box. This method does not require personnel to assist in adjusting the height of the prefabricated beam, and can facilitate the installation of the prefabricated beam and the embedded bar on the prefabricated beam. In addition, during the process of pushing the prefabricated beam to move with the sliding support, the elastic telescopic component is in a deformed state, so the elastic telescopic component has a force to push the sliding support upward, which can reduce the resistance between the sliding support and the elastic telescopic component, so that the sliding support can slide more smoothly along the elastic telescopic component.
[0012] Optionally, a second limiting component is further included, and the second limiting component includes a limiting plate.
[0013] The first guide and the second guide are arranged on the second limiting component, the sliding support is slidably connected to the limiting plate through the guidance of the first guide and the second guide, the first guide is used to guide the sliding of the sliding support along the telescopic direction of the elastic telescopic component, and the second guide is used to guide the sliding of the sliding support along the direction perpendicular to the telescopic direction of the elastic telescopic component.
[0014] In addition, the second guide is located at one end of the first guide close to the bottom support.
[0015] By adopting the technical scheme, when the first guide member limits the sliding support member, the sliding support member can be prevented from sliding in the horizontal direction, so as to reduce the situation that the sliding support member is separated from the elastic telescopic assembly.
[0016] Optionally, the pushing assembly is further arranged between the bottom support member and the sliding support member, and the pushing assembly comprises a material blocking seat, a sliding telescopic assembly and a second elastic member.
[0017] The material blocking seat is fixedly connected to the bottom support member.
[0018] The sliding telescopic assembly comprises a middle pushing plate and a top sliding plate.
[0019] The top sliding plate is fixedly connected to the sliding support member and is slidingly connected to the middle pushing plate along the telescopic direction of the elastic telescopic assembly.
[0020] The second elastic member is arranged between the middle pushing plate and the material blocking seat.
[0021] When the sliding support member is guided by the first guide member, the second elastic member is in a deformed state; when the sliding support member is guided by the second guide member, the second elastic member gradually recovers from the deformation, and the second elastic member generates a force to push the middle pushing plate to slide away from the material blocking seat during the recovery from the deformation.
[0022] By adopting the technical scheme, when the sliding support member is driven downward by the precast beam to the first limiting assembly, the sliding support member can be guided by the second guide member, and at this time, the second elastic member can push the middle pushing plate to move toward the precast column side, so that the precast beam can be pushed toward the precast column side without additional operation of personnel, which can further facilitate the precast beam to be positioned at the installation position.
[0023] Optionally, a horizontal rod is fixedly connected to the middle pushing plate, the horizontal rod is slidingly connected to the material blocking seat, and the horizontal rod is parallel to the sliding support member along the sliding direction of the material blocking seat.
[0024] By adopting the technical scheme, when the horizontal rod guides the movement of the middle pushing plate, the middle pushing plate can be prevented from deviating, and the stability of the movement of the middle pushing plate can be ensured.
[0025] Optionally, the pushing assembly further comprises a first wedge-shaped block, a bottom sliding plate and a third elastic member.
[0026] The first wedge-shaped surface is inclined towards the side close to the bottom support from the direction of the material blocking seat to the middle pushing plate.
[0027] One end of the bottom sliding plate is slidingly connected to the middle pushing plate, the third elastic member is always in a deformed state, one end of the third elastic member is fixedly connected to the middle pushing plate, and the other end is fixedly connected to the bottom sliding plate.
[0028] The third elastic member in the deformed state has a force to push the bottom sliding plate to be pressed against the first wedge-shaped surface.
[0029] By adopting the above technical scheme, when the second elastic member restores the deformation and pushes the precast beam to move with the sliding support to one side of the precast column, since the third elastic member always pushes the bottom sliding plate to be pressed against the first wedge-shaped surface, the bottom sliding plate has a supporting effect on the middle pushing plate, and the setting of the first wedge-shaped surface can facilitate the downward sliding of the bottom sliding plate, so that the middle pushing plate can slide more smoothly to one side of the precast column in cooperation with the pushing force of the second elastic member.
[0030] Optionally, the bottom sliding plate is freely rotatably connected with a second ball, and the second ball is in contact with the first wedge-shaped surface.
[0031] By adopting the above technical scheme, when the bottom sliding plate slides downward along the first wedge-shaped surface, the second ball rolls on the first wedge-shaped surface, and the setting of the second ball can make the downward movement of the bottom sliding plate along the first wedge-shaped surface more smooth.
[0032] Optionally, the bottom support is provided with at least one second limiting assembly on each side in the sliding direction of the sliding support, the second limiting assembly further comprises a guide plate, the guide plate is fixedly connected to the side of the limiting plate away from the bottom support, and the distance between the two guide plates gradually increases away from the bottom support.
[0033] By adopting the above technical scheme, in order to further facilitate the insertion of the embedded bar on the precast beam into the steel box, the distance between the two limiting plates can be set to be consistent with the horizontal width of the precast beam, so that when the precast beam is located between the two limiting plates, the precast beam can be moved to the designed position by horizontally moving the precast beam, and the setting of the guide plate can facilitate the insertion of the precast beam between the two limiting plates in cooperation with the change of the distance between the two guide plates.
[0034] Optionally, it further comprises a hoop assembly, the hoop assembly comprises two connecting seats, a groove is formed on one side of the connecting seat, and the two connecting seats are detachably connected.
[0035] The bottom support is detachably connected to the connecting seat.
[0036] By adopting the technical scheme, the connecting seat is moved to enable the precast column to be located in the groove, and then the two connecting seats are fixed, so that the hoop assembly is connected to the precast column. By arranging the hoop assembly, the device for assisting the splicing of the precast beam column can be fixed to the precast column.
[0037] Optionally, the locking assembly further includes a second wedge block and a third wedge block.
[0038] The second wedge block is slidably connected to the connecting seat along the extension direction of the elastic extension assembly, and the second wedge block includes a second wedge surface, which is inclined to the side away from the sliding support along the direction from the middle pushing plate to the blocking seat.

Detailed Implementation
[0060] The following is in conjunction with the appendix Figures 2-12 This application will be described in further detail.
[0061] This application discloses a device for assisting in the splicing of precast beams and columns. (Refer to...) Figure 2 and Figure 3 The device used to assist in the splicing of prefabricated beams and columns includes a bottom support 2, an elastic telescopic component 3, and a sliding support 4.
[0062] Reference Figure 2 The bottom support 2 is a horizontally placed long strip plate, and the long side of the bottom support 2 is parallel to the long side of the precast beam 11 located at the installation height. In use, the bottom support 2 can be fixed to the precast column 12.
[0063] Reference Figure 2 and Figure 3, a plurality of elastic telescopic components 3 are arranged on the bottom support 2, the elastic telescopic component 3 comprises a fixed rod 31, a movable rod 32 and a first elastic element 33, the fixed rod 31 is hollow and arranged, the movable rod 32 is arranged parallel to the fixed rod 31, and the bottom end of the movable rod 32 is slidingly connected to the fixed rod 31 in the length direction of the fixed rod 31; in the embodiment, the first elastic element 33 is a compression spring sleeved on the outer periphery of the movable rod 32, one end of the first elastic element 33 is welded to the end wall of the fixed rod 31, and the other end is welded to the outer peripheral wall of the end of the movable rod 32 away from the fixed rod 31, so that the elastic sliding connection between the fixed rod 31 and the movable rod 32 is realized by the first elastic element 33.
[0064] With reference to Figure 2 and Figure 3 , the bottom wall of the fixed rod 31 is welded to the top wall of the bottom support 2, the elastic telescopic component 3 is vertically placed as a whole, and a plurality of elastic telescopic components 3 are distributed in two rows on the bottom support 2, and each row of elastic telescopic components 3 is distributed in the length direction of the bottom support 2.
[0065] With reference to Figure 2 and Figure 3 , the sliding support 4 is lapped on the top wall of the plurality of elastic telescopic components 3, and the long side of the sliding support 4 is arranged parallel to the long side of the bottom support 2; in order to enable the sliding support 4 to slide along the elastic telescopic component 3, two dovetail grooves 41 are formed in the bottom wall of the sliding support 4 in the length direction of the sliding support 4, a dovetail block 34 adapted to the dovetail groove 41 is welded to the top wall of the movable rod 32, and the dovetail block 34 is located in the dovetail groove 41, so that the sliding support 4 can slide on the elastic telescopic component 3 in the length direction of the bottom support 2.
[0066] With reference to Figure 4 , in order to avoid that the first elastic element 33 cannot recover the deformation due to excessive gravity of the precast beam 11, a plurality of first limiting components 5 are further arranged on the bottom support 2, in the embodiment, the first limiting component 5 is arranged in two rows, and each row of the plurality of first limiting components 5 is arranged in sequence in the length direction of the sliding support 4, and an avoiding space 53 is formed between the adjacent two rows of first limiting components 5; the first limiting component 5 comprises a limiting rod 51 and a first ball 52; the limiting rod 51 is welded to the top wall of the bottom support 2, and the first ball 52 is embedded in the top wall of the limiting rod 51, and the first ball 52 can rotate freely at the top end of the limiting rod 51;
[0067] In order to facilitate the distinction, the initial height of the sliding support 4 is that a gap is formed between the sliding support 4 and the first limiting component 5 in the sliding direction of the elastic telescopic component 3;
[0068] The installation position of the sliding support 4 is that the sliding support 4 is lapped on the first limiting component 5;
[0069] Thus, when the sliding support 4 is pressed down from the initial height to the first ball 52, the sliding support 4 at this time is at the installation height, the first elastic member 33 at this time is in the deformed state of recoverable deformation, and the precast beam 11 lapped on the sliding support 4 is at the design height, that is, only the precast beam 11 needs to be horizontally pushed to make the embedded part 13 on the precast beam 11 located in the steel box 14.
[0070] With reference to Figure 5 Then, the height of the precast beam 11 can be positioned by the first limiting assembly 5, and in order to limit the position of the precast beam 11 in the horizontal direction, the application also provides two second limiting assemblies 6, and the second limiting assembly 6 comprises a limiting plate 61 and a guide plate 62. The limiting plate 61 is vertically welded to the top wall of the bottom support 2, and the bottom support 2 is provided with one limiting plate 61 on each side of the long side thereof. When the precast beam 11 is clamped between the two limiting plates 61, the precast beam 11 is at the design position in the horizontal direction, that is, only the precast beam 11 needs to be moved along the long side direction thereof to make the embedded part 13 inserted into the steel box 14, and then the precast beam 11 can be moved to the final design position. The guide plate 62 is welded to the top wall of the limiting plate 61. In order to facilitate the insertion of the precast beam 11 between the two limiting plates 61, the guide plate 62 is an arc plate, and the arc-shaped openings of the two guide plates 62 face away from each other, so that the spacing between the two guide plates 62 gradually decreases from top to bottom, so that even if the hoisting position of the precast beam 11 by the crane is deviated, the precast beam 11 can be inserted between the two limiting plates 61 under the guidance of the guide plate 62 without human assistance.
[0071] With reference to Figure 5 and Figure 6, the sliding support 14 is at the initial height; when the precast beam 11 is placed on the sliding support 4 and the sliding support 4 is pressed to contact the first ball 52, the precast beam 11 and the sliding support 4 are at the installation height; in order to avoid the sliding support 4 sliding along the horizontal direction at the initial height, and in order to enable the precast beam 11 to move horizontally with the sliding support 4 at the installation height, the limiting plate 61 is provided with a first guide and a second guide on the side close to the sliding support 4, in the embodiment, the first guide is a longitudinal guide groove 611 opened on the limiting plate 61, and the second guide is a horizontal guide groove 612 opened on the limiting plate 61, the longitudinal guide groove 611 is vertically opened, the horizontal guide groove 612 is horizontally opened, and the horizontal guide groove 612 is communicated with the side of the bottom end of the longitudinal guide groove 611 close to the precast column 12; the sliding support 4 is welded with a guide column 42 on each side wall of the long side of the sliding support 4, the guide column 42 is a cylinder, the axis of the guide column 42 is horizontally and perpendicularly arranged to the long side of the sliding support 4, and the end of the guide column 42 can slide along the long side of the groove in the longitudinal guide groove 611 and the horizontal guide groove 612; when the guide column 42 is located in the horizontal guide groove 612, the precast beam 11 and the sliding support 4 are at the installation height; therefore, after the precast beam 11 is placed on the sliding support 4, the precast beam 11 presses the sliding support 4 to move downward, and the guide column 42 will move downward with the sliding support 4, and when the guide column 42 moves to the horizontal guide groove 612, the guide column 42 can move in the horizontal guide groove 612 along the horizontal direction towards the side of the precast column 12.
[0072] In order to push the sliding support 4 at the installation height to move towards the side of the precast column 12, the application further comprises a plurality of pushing assemblies 7, the pushing assemblies 7 are arranged between the bottom support 2 and the sliding support 4, and the plurality of pushing assemblies 7 are distributed along the long side direction of the bottom support 2; in order to avoid the pushing assembly 7 interfering with the limiting rod 51, the pushing assembly 7 is located in the avoiding space 53.
[0073] Referring to Figure 7 and Figure 8The pushing assembly 7 comprises a material blocking seat 71, a sliding telescopic assembly 72, a second elastic member 73 and a first wedge-shaped block 76. The material blocking seat 71 is welded to the top wall of the bottom support 2. The sliding telescopic assembly 72 is located at one side of the material blocking seat 71 close to the precast column 12. The sliding telescopic assembly 72 comprises a top sliding plate 721, a middle pushing plate 722 and a bottom sliding plate 723. The middle pushing plate 722 is connected between the top sliding plate 721 and the bottom sliding plate 723. The second elastic member 73 is welded to one side of the middle pushing plate 722 close to the material blocking seat 71. The second elastic member 73 is a compression spring with the telescopic direction parallel to the horizontal guide groove 612. One side of the second elastic member 73 close to the material blocking seat 71 abuts against the material blocking seat 71. In order to ensure that the middle pushing plate 722 can move horizontally, a horizontal rod 74 is welded to the middle pushing plate 722. The horizontal rod 74 is arranged through the material blocking seat 71 and can slide on the material blocking seat 71 in the horizontal direction to guide the movement of the middle pushing plate 722 horizontally.
[0074] With reference to Figure 8 The top end of the top sliding plate 721 is welded to the bottom wall of the sliding support 4. The bottom sliding plate 723 is connected to the middle pushing plate 722 in the vertical direction. In order to avoid the interference between the bottom sliding plate 723 and the top sliding plate 721, the bottom sliding plate 723 and the top sliding plate 721 are arranged in the horizontal direction.
[0075] With reference to Figure 8 When the sliding support 4 is at the initial height and the second elastic member 73 is in the compressed state, the top sliding plate 721 will slide downward along the middle pushing plate 722 under the pressure of the sliding support 4 during the process that the sliding support 4 is lowered from the initial height to the installation height. When the top sliding plate 721 slides downward with the sliding support 4 to the installation height of the sliding support 4, the guide column 42 on the sliding support 4 will be located at the communication between the longitudinal guide groove 611 and the horizontal guide groove 612. The guide column 42 will lose the horizontal restriction of the longitudinal guide groove 611. At this time, the second elastic member 73 will change from the compressed state to the normal state to push the middle pushing plate 722 to move toward the side of the precast column 12. The top sliding plate 721 and the sliding support 4 will move toward the side of the precast column 12 with the middle pushing plate 722.
[0076] With reference to Figure 8The first wedge-shaped block 76 is welded to the top wall of the bottom support 2, and the first wedge-shaped block 76 comprises a first wedge-shaped surface 761, which is arranged downwardly and obliquely from the material blocking seat 71 to the middle pushing plate 722, and the bottom end of the bottom sliding plate 723 is pressed against the first wedge-shaped surface 761. In order to ensure that the bottom end of the bottom sliding plate 723 is always pressed against the first wedge-shaped surface 761, a first lug 7232 is welded to each side of the bottom sliding plate 723 in the sliding direction. The third elastic member 75 is a compression spring, the top end of the third elastic member 75 is welded to the bottom wall of the middle pushing plate 722, and the bottom end of the third elastic member 75 is welded to the first lug 7232. When the sliding support 4 is at the initial height, the third elastic member 75 is in a compressed state, and as the middle pushing plate 722 starts to slide horizontally towards one side of the precast column 12, the third elastic member 75 gradually recovers to the normal state, so that the bottom sliding plate 723 is always pushed by the third elastic member 75 to press against the first wedge-shaped surface 761. Further, in order to facilitate the downward sliding of the bottom sliding plate 723 along the first wedge-shaped surface 761, a second ball 7231 is embedded at the bottom end of the bottom sliding plate 723, and the second ball 7231 can rotate freely at the bottom end of the bottom sliding plate 723, so that when the bottom sliding plate 723 slides downward along the first wedge-shaped surface 761, it can slide downward more smoothly through the rolling action of the second ball 7231.
[0077] With reference to Figure 9 and Figure 10 In the present application, after the precast beam 11 is pressed against the sliding support 4, due to the heavy weight of the precast beam 11, in order to connect the bottom support 2 and the precast column 12 more firmly, the present application further comprises a hoop assembly 8, a locking assembly 9 and a pressing assembly 10.
[0078] With reference to Figure 9 and Figure 10 The hoop assembly 8 comprises two connecting seats 81, the side close to each other of the two connecting seats 81 is provided with a groove 82 for accommodating the precast column 12, the side close to each other of the two connecting seats 81 is welded with a second lug 83, and the second lugs 83 on the two connecting seats 81 are detachably connected through screws. The end of the bottom support 2 close to the precast column 12 is fixedly connected to the connecting seat 81 through screws.
[0079] With reference to Figure 11The locking assembly 9 comprises a second wedge block 91, a third wedge block 92, a sliding block 93 and a fourth elastic member 94. The connecting seat 81 is provided with an elongated accommodating chamber 84.

The second wedge block 91 is located in the accommodating chamber 84 and can slide along the long side of the accommodating chamber 84. The second wedge block 91 comprises a second wedge surface 911 which is inclined to the side away from the sliding support 4 from the middle pushing plate 722 to the material blocking seat 71.
[0080] With reference to Figure 11 , the connecting seat 81 is further provided with a sliding groove 85. The long side of the sliding groove 85 is parallel to the horizontal rod 74 and arranged along the sliding direction of the material blocking seat 71. One end of the sliding groove 85 is in communication with the accommodating chamber 84, and the other end is in communication with the groove 82. The third wedge block 92 is located in the sliding groove 85. The third wedge block 92 comprises a third wedge surface 921 which is parallel to the second wedge surface 911. The third wedge surface 921 is in contact with the second wedge surface 911. Therefore, when the second wedge block 91 moves to the side away from the sliding support 4, the third wedge block 92 is pushed to move to the side of the groove 82, so as to clamp the prefabricated column 12.
[0081] With reference to Figure 11 , in order to avoid the third wedge block 92 from falling off the connecting seat 81, the connecting seat 81 is further provided with a limiting groove 86 which is in communication with the sliding groove 85. The sliding block 93 is located in the limiting groove 86 and in contact with the groove wall of the limiting groove 86, so as to be guided by the groove wall of the limiting groove 86. The sliding block 93 is welded to the third wedge block 92, so that the sliding block 93 moves with the third wedge block 92. The fourth elastic member 94 is a compression spring. One end of the fourth elastic member 94 is welded to the sliding block 93, and the other end is welded to the inner wall of the limiting groove 86 close to the prefabricated column 12.
[0082] With reference to Figure 10 and Figure 11 , in order to improve the clamping effect on the prefabricated column 12, the locking assembly 9 on each connecting seat 81 is provided with a plurality of longitudinal columns, and each longitudinal column comprises a plurality of locking assemblies 9. When the plurality of second wedge blocks 91 move to the side away from the sliding support 4, the plurality of second wedge blocks 91 push the plurality of third wedge blocks 92 to be pressed to the side of the prefabricated column 12.
[0083] With reference to Figure 9 , Figure 11 and Figure 12, further, the down-pressing assembly 10 is used to drive the second plurality of wedge-shaped blocks 91 to move synchronously, and the down-pressing assembly 10 comprises a first down-pressing rod 100, a down-pressing plate 101, a second down-pressing rod 102 and a third down-pressing rod 103. The first down-pressing rod 100 is vertically arranged and welded to the bottom wall of the sliding support 4, and the down-pressing plate 101 is horizontally arranged, one end of the down-pressing plate 101 is in contact with the side of the first down-pressing rod 100 away from the sliding support 4, and the other end extends to the steel box 14.
[0084] Referring to Figure 11 and Figure 12 , the second down-pressing rod 102 is arranged through the connecting seat 81 and can slide in the vertical direction on the connecting seat 81, and each second down-pressing rod 102 is welded to each column of the plurality of second wedge-shaped blocks 91, the second down-pressing rod 102 extends upwards above the connecting seat 81, and the third down-pressing rod 103 is welded to the side of the plurality of second down-pressing rods 102 extending above the connecting seat 81; and the side of the down-pressing plate 101 close to the steel box 14 is welded to the third down-pressing rod 103; therefore, when the sliding support 4 is pressed down, the down-pressing plate 101 is pressed down by the first down-pressing rod 100; in addition, since the first down-pressing rod 100 is in contact with the down-pressing plate 101, the sliding support 4 will not be stuck by the first down-pressing rod 100, and the first down-pressing rod 100 can be driven to move towards the side of the precast column 12; when the down-pressing plate 101 is pressed down, the second down-pressing rod 102 and the third down-pressing rod 103 are also pressed down, so that the second wedge-shaped block 91 welded to the second down-pressing rod 102 is pressed against the third wedge-shaped block 92, so that the third wedge-shaped block 92 tightly abuts against the precast column 12.
[0085] The implementation principle of the device for assisting the splicing of the precast beam column is as follows: during construction, first, the device for assisting the splicing of the precast beam column is installed on the precast column 12, then, the precast column 12 provided with the device for assisting the splicing of the precast beam column is vertically placed on the foundation, and then, the precast beam 11 is placed on the sliding support 4 by using a crane; the sliding support 4 drives the third wedge-shaped block 92 in the locking assembly 9 to tightly abut against the precast column 12 by the down-pressing assembly 10.
[0086] In addition, after the sliding support 4 is pressed down from the preset height to the installation height, the second elastic member 73 drives the middle pushing plate 722 to move towards the side of the precast column 12, so that the middle pushing plate 722 drives the sliding support 4 to move towards the side of the precast column 12 through the top sliding plate 721, so that the embedded part 13 on the precast beam 11 is inserted into the steel box 14.
[0087] And, in the process that the second elastic member 73 moves the middle pushing plate 722 to the side of the precast column 12, the first wedge surface 761 on the first wedge block 76 can also accelerate the movement of the middle pushing plate 722 to the side of the precast column 12; finally, after the precast column 12 and the precast beam 11 are fixed in the steel box 14 by pouring concrete, the device for assisting the splicing of the precast beam-column can be removed.
[0088] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
