Description

Technical Field

[0001] The present application relates to the technical field of prefabricated buildings, and in particular to a prefabricated building component connection structure. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] Among them, in the prefabricated concrete frame structure system, prefabricated beam-column connection nodes often play a decisive role in structural performance (such as bearing capacity, structural stiffness, seismic performance, etc.). The design of prefabricated building beam-column connection nodes can be customized according to different building needs and design requirements, providing more flexibility and selectivity, and can be installed on site quickly and accurately, reducing the time and labor costs of on-site construction.

[0004] Existing prefabricated beam-column joints usually assemble and install connecting structures for beam assembly on the columns. After the connecting structures are assembled and installed on the four sides of multiple columns, the beams are assembled and installed between adjacent columns. However, the process of assembling and installing the connecting structures on multiple columns one by one is time-consuming and labor-intensive, and will also affect the construction efficiency of prefabricated buildings. Summary of the invention

[0005] The present application provides a prefabricated building component connection structure, which can effectively reduce the labor cost of prefabricated beam-column connection node construction, and at the same time can effectively improve the efficiency of prefabricated beam-column connection node construction.

[0006] The present application provides a prefabricated building component connection structure, which adopts the following technical solution: An assembled building component connection structure is arranged on a column, and the column is a hollow rectangular parallelepiped structure with a square cross section, comprising a frame, four connecting pieces and a plurality of locking components; The frame body includes a clamping frame, four connecting frames and four positioning members; the clamping frame is a cross frame structure, which has four clamping parts extending outward, and the four connecting frames are respectively arranged at the ends of the four clamping parts; the top of the column is provided with clamping grooves at the four diagonal positions along the length direction of the column, and when the four clamping parts are respectively clamped with the four clamping grooves, the connecting frame is located on the outside of the column, and the four connecting frames are respectively in contact with and abut against the four diagonal corners of the column; the four connecting members correspond to the four sides of the column one by one, and the connecting member is detachably connected to the two adjacent connecting frames, and after the connection, the connecting member is in contact with and abuts against one side of the column; The four positioning members are respectively sleeved on the four clamping parts, the end surfaces of the clamping parts have threads, the inner sides of the positioning members also have threads, and the positioning members can be threadedly matched with the corresponding clamping parts; when the positioning members are completely threadedly matched with the search clamping parts, the positioning members and the corresponding connecting frames jointly clamp the corresponding diagonal positions of the column; The locking assembly includes a bolt and a nut; a first clearance hole is provided on the connecting frame, a second clearance hole is provided on the connecting piece, and a third clearance hole is provided on the column; after the tail of the bolt passes through the first clearance hole, the second clearance hole and the third clearance hole in turn, the nut cooperates with the threaded tail of the bolt to enable the connecting frame, the connecting piece and the column to lock their positions with each other.

[0007] By adopting the above technical solution, it is convenient for construction workers to simultaneously assemble and install four connection structures for assembling and installing the beam body on the column, thereby effectively reducing the labor cost of constructing the prefabricated beam-column connection node and effectively improving the efficiency of the construction of the prefabricated beam-column connection node.

[0009] By adopting the above technical solution, the rolling element can make the frame body move and adjust the position more smoothly when the clamping portion and the clamping groove are clamped together, thereby improving the efficiency of determining the installation and fixing position of the frame body on the column.

[0010] Optionally, the rolling element is elastic, and the rolling element in the clamping groove can contact and abut against groove walls on both sides of the clamping groove at the same time.

[0011] By adopting the above technical solution, the rolling element can further make the process of the frame moving and adjusting the position smoother when the clamping portion and the clamping groove are clamped together, and at the same time can effectively reduce the probability of the rolling element causing damage to the column.

[0012] Optionally, the positioning member has an extrusion portion at one end close to the adjacent connecting frame; when the positioning member and the clamping portion are fully threadedly matched, the extrusion portion enters the adjacent clamping groove and squeezes the corresponding rolling member to deform it, and the contact area between the deformed rolling member and the two side groove walls of the clamping groove is increased.

[0013] By adopting the above technical solution, the rolling element can improve the relative position stability between itself and the column after being squeezed and deformed, thereby further improving the relative position stability between the frame and the column, and further improving the structural stability of the frame after being assembled and installed on the column.

[0014] Optionally, when the positioning member and the clamping portion are fully threadedly matched, the portion of the rolling member that has been squeezed and deformed will be clamped between the positioning member and the inner surface of the column.

[0015] By adopting the above technical solution, the probability of causing damage to the column during the threaded engagement of the positioning member and the clamping portion can be reduced. At the same time, the position stability of the positioning member relative to the column after the positioning member and the clamping portion are fully threaded together can be improved, thereby further improving the structural stability of the frame after being installed on the column.

[0016] Optionally, both sides of the connecting member have matching parts, and both sides of the connecting frame have matching grooves adapted to the matching parts, and when the two matching parts on the same connecting member are respectively engaged with the matching grooves on two adjacent connecting frames, the connecting member contacts and abuts against the column; The second easing hole and the third easing hole are both waist-shaped holes extending in the same direction, the first easing hole is communicated with the matching groove, and the second easing hole is provided on the matching portion.

[0017] By adopting the above technical solution, the assembly and installation process of the connecting parts on the frame can be made more convenient, and the position adjustment of the connecting parts after the initial assembly and installation on the frame can be facilitated to improve the effect of subsequent prefabricated beam-column structure construction.

[0018] Optionally, a plurality of limiting members are provided at the bottom of the connecting frame, the connecting member can move relative to the connecting frame and the moving direction is the same as the extending direction of the second clearance hole, and the limiting members can prevent the connecting member from moving so that the matching portion leaves the matching groove; The top of the connecting frame is connected to a plurality of extension seats, and the extension seats are movably connected to a plurality of adjustment members; the movement direction of the adjustment members is parallel to the movement direction of the connecting members, and the adjustment members can contact and abut against the top of the connecting members during movement.

[0019] By adopting the above technical solution, it is convenient for construction workers to adjust the assembly and installation position of the connecting piece on the frame, and at the same time, the probability of the connecting piece being detached from the frame due to excessive position adjustment can be reduced, thereby effectively improving the safety of construction.

[0020] Optionally, an end surface of the mating portion facing away from the column and a groove wall of the mating groove opposite to the column are both inclined surfaces, and the distance between the inclined surface of the mating groove and the surface of the column gradually decreases downward.

[0021] By adopting the above technical solution, the probability of the connecting part spontaneously changing its position relative to the frame under the action of its own gravity can be reduced. At the same time, after the position of the connecting part is adjusted, the force exerted by the connecting part on the frame and the column is increased, so that the friction force is also increased, thereby improving the position stability of the connecting part relative to the column and the position stability of the frame relative to the column.

[0022] Optionally, a side of the connecting member that abuts against the surface of the column is provided with an elastic protective layer.

[0023] By adopting the above technical solution, the probability of the connecting piece spontaneously changing its position relative to the frame under the action of its own gravity can be further reduced, and at the same time, the probability of damaging the column surface during the position adjustment of the connecting piece can be effectively reduced.

[0024] Optionally, a clearance groove is provided on the side of the positioning member facing away from the corresponding connecting frame. When the positioning member is fully threadedly engaged with the clamping portion, the tail ends of several of the bolts can be located on one side of the positioning member after passing through the interior of the column. When the corresponding nut is threadedly engaged with the tail end of the bolt, the nut can partially enter the clearance groove and contact and abut against the positioning member, and the threaded engagement direction of the nut and the bolt is opposite to the threaded engagement direction of the positioning member and the clamping portion.

[0025] By adopting the above technical solution, the nut and the bolt threads are matched and contacted with the positioning piece, which can have a positioning effect on the positioning piece, and the nut and the positioning piece have opposite rotation directions and can form an interlocking, thereby simultaneously improving the position fixing and locking effect of the positioning piece and the locking assembly, and further improving the structural stability of the frame and the four connecting parts after being assembled and installed on the column.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a prefabricated building component connection structure, which is constructed on the top of the column 1 and is used for the beam to be assembled and installed on the side of the top of the column 1. In this embodiment, the column 1 is preferably a hollow rectangular parallelepiped structure with a square cross section, and the internal space of the column 1 runs through both ends of itself along its length direction, and the cross section of its internal space is also square; since the prefabricated beam is a prior art in the art, it is not further limited here, and it is omitted in the drawings.

[0031] Reference Figure 1 and Figure 3 The prefabricated building component connection structure includes a frame 2, four connectors 3 and a plurality of locking components 4. The frame 2 is used for the four connectors 3 to simultaneously connect with the column 1, so that the construction workers can simultaneously construct four connection structures for the assembly and installation of the beam on the column 1; the connector 3 provides a connection node for the assembly and installation between the beam and the column 1; and the locking components 4 are used to improve the relative position stability between the frame 2, the connector 3 and the column 1.

[0032] Reference Figure 2 and Figure 3 The frame body 2 is a cross frame structure as a whole, including a clamping frame 21 and four connecting frames 22, wherein the clamping frame 21 is a cross structure as a whole, and the connecting frame 22 is a rectangular strip structure as a whole.

[0033] The four ends of the clamping frame 21 each extend outwardly with a clamping portion 211, which is in the form of a cylindrical body 1. The axis of the clamping portion 211 coincides with its own extension direction, the axes of the four clamping portions 211 are located in the same plane, and the axes of adjacent clamping portions 211 are perpendicular to each other.

[0034] The four connecting frames 22 correspond to the four clamping parts 211 one by one, and the connecting frames 22 are fixedly installed at the ends of the corresponding clamping parts 211. The length directions of the four connecting frames 22 are parallel to each other, and the length directions of the connecting frames 22 are perpendicular to the axes of the corresponding clamping parts 211. In this embodiment, it is preferred that the position where the connecting frame 22 is fixedly connected to the corresponding clamping part 211 is centered along its length direction.

[0035] The top of the column 1 is provided with engaging grooves 11 for engaging the engaging portion 211 at four diagonal positions. The engaging grooves 11 extend along the length direction of the column 1 and penetrate the top of the column 1 to form an opening for the engaging portion 211 to enter the engaging grooves 11 .

[0036] After the frame 2 is assembled and installed on the column 1, the four snap-fit ​​parts 211 will be snap-fitted with the four snap-fit ​​grooves 11 respectively, and the cross structure of the snap-fit ​​frame 21 will be located as a whole in the internal space of the column 1. The four connecting frames 22 are all located on the outside of the column 1 and are respectively close to the four diagonal positions of the column 1; at this time, the frame 2 can be moved relative to the column 1 along the length direction of the column 1 to adjust its position, so that the frame 2 can determine its assembly and installation position on the column 1 in the hoisting state.

[0037] The frame 2 also includes four positioning members 23 for fixing the relative position with the column 1, and the four positioning members 23 correspond to the four clamping parts 211 one by one. The positioning members 23 are sleeved and installed on the corresponding clamping parts 211, and the surface of the clamping parts 211 close to the corresponding connecting frame 22 has an external thread, and the inner surface of the positioning members 23 has an internal thread adapted thereto. When the positioning members 23 move to a certain position toward one end close to the corresponding connecting frame 22, the positioning members 23 can be threadedly matched with the clamping parts 211, and when the positioning members 23 and the clamping parts 211 are completely threadedly matched, the positioning members 23 can contact and abut against two adjacent inner surfaces of the column 1; when the four positioning members 23 are all in contact with and abut against the inner surface of the column 1, the frame 2 can be fixed relative to the column 1 under the friction between the positioning members 23 and the column 1. In this embodiment, it is preferred that the end of the positioning members 23 away from the corresponding connecting frame 22 has a structure that is convenient for construction personnel to control its rotation so that it can be threadedly matched with the clamping parts 211.

[0038] Furthermore, in order to facilitate the position adjustment of the frame 2 relative to the column 1 in a hoisting manner, the frame 2 preferably further includes four elastic rolling elements 24, and the four rolling elements 24 correspond one to one to the four clamping portions 211. In this embodiment, the rolling elements 24 are preferably made of rubber material.

[0039] Before the frame 2 is fixed relative to the column 1, the rolling member 24 is in a spherical structure as a whole, and is sleeved and installed on the corresponding clamping portion 211, located between the portion with external threads on the surface of the clamping portion 211 and the corresponding connecting frame 22, and can rotate relative to the clamping portion 211 with the axis of the clamping portion 211 as the axis.

[0040] When the clamping part 211 is clamped into the clamping groove 11 and the frame 2 is adjusted relative to the column 1, the rolling element 24 can contact and abut against the groove walls on both sides of the clamping groove 11 at the same time to prevent the clamping part 211 from directly contacting the clamping groove 11. In the above process, the rolling element 24 can drive the clamping part 211 to maintain a central position in the clamping groove 11, thereby improving the effect of determining the assembly and installation position of the subsequent frame 2 relative to the column 1; when the frame 2 shakes or swings during the position adjustment process, causing the rolling element 24 to be in close contact with one side of the groove wall of the clamping groove 11 and separated from the other side of the groove wall, the rolling element 24 can rotate relative to the corresponding clamping part 211 as the frame 2 is adjusted, making the movement of the frame 2 smoother, and the rolling element 24 can also correct the deviation of the frame 2.

[0041] Furthermore, in order to further improve the position stability of the frame 2 after being fixed relative to the column 1, the end of the positioning member 23 close to the corresponding connecting frame 22 preferably has an extrusion portion 231 for extruding the rolling member 24, and the rolling member 24 can be deformed by extrusion.

[0042] When the positioning member 23 is fully threadedly engaged with the clamping portion 211 until it contacts and abuts against the inner surface adjacent to the column 1, the extrusion portion 231 will enter the corresponding clamping groove 11 to squeeze the corresponding rolling member 24. At this time, the rolling member 24 is squeezed and deformed, and its contact area with the groove walls on both sides of the clamping groove 11 is increased. At the same time, the part of the rolling member 24 close to the positioning member 23 is squeezed and deformed, and then partially located between the positioning member 23 and the inner surface of the column 1 and clamped in place (the above-mentioned part of the rolling member 24 is omitted in the accompanying drawings); at this time, the position stability of the positioning member 23 and the rolling member 24 relative to the column 1 is significantly improved, thereby effectively improving the position stability of the frame 2 relative to the column 1.

[0043] Reference Figure 3 and Figure 4 The connecting piece 3 is a rectangular plate-shaped structure as a whole, and both ends of the connecting piece 3 extend outward to form a matching portion 31 that is convenient for it to form a connection with the connecting frame 22; both ends of the connecting frame 22 near the adjacent outer surface of the column 1 have matching grooves 221 that are adapted to the matching portion 31. After the two matching portions 31 on the connecting piece 3 enter the two matching grooves 221 on the two adjacent connecting frames 22 respectively, the end face of one side of the connecting piece 3 near the column 1 can fit against the corresponding side surface of the column 1. At this time, the connecting piece 3 can move and adjust its position relative to the frame 2 along the length direction of the column 1, which is convenient for construction personnel to adjust the assembly and installation positions of different connecting pieces 3 on the column 1 according to actual conditions.

[0044] Reference Figure 1 and Figure 4 Furthermore, in order to reduce the probability of the connection member 3 being separated from the connection frame 22 during the process of adjusting the position relative to the frame body 2, a limiting member 25 is preferably fixedly installed at the bottom of the connection frame 22, and the limiting member 25 covers the opening at the bottom of the matching groove 221. In this embodiment, preferably four limiting members 25 are fixedly installed at the bottom of the frame body 2, and preferably the limiting members 25 are fixedly connected to the connection frame 22 by welding.

[0045] Reference Figure 3 and Figure 4The locking assembly 4 includes a bolt 41 and a nut 42; a plurality of first clearance holes 222 are provided on the connecting frame 22 for the tail of the bolt 41 to pass through, and the opening direction of the first clearance hole 222 is perpendicular to the outer surface adjacent to the column 1, one end of the first clearance hole 222 passes through the end surface of the connecting frame 22 away from the column 1 and the other end is connected to the matching groove 221, and the first clearance hole 222 is adapted to the tail of the bolt 41, so that the bolt 41 and the connecting frame 22 are conveniently penetrated and matched; the connecting member 3 has a plurality of second clearance holes 311 on its two matching parts 31 for the tail of the bolt 41 to pass through, The multiple second clearance holes 311 on the matching portion 31 correspond one-to-one to the multiple first clearance holes 222 that communicate with the corresponding matching grooves 221 on the connecting frame 22. The second clearance holes 311 are waist-shaped holes and their extension direction is parallel to the direction in which the subsequent connecting member 3 is adjusted relative to the frame body 2; a plurality of third clearance holes 12 for the tail of the bolt 41 to pass through are correspondingly opened on the column 1. The multiple third clearance holes 12 located on the same side of the column 1 correspond one-to-one to the multiple second clearance holes 311 on the connecting member 3 on the same side. The third clearance holes 12 are also waist-shaped holes and their extension direction is parallel to the length direction of the column 1.

[0046] The tail end of the bolt 41 passes through the first clearance hole 222, the second clearance hole 311 and the third clearance hole 12 in turn until the head of the bolt 41 contacts and abuts against the connecting frame 22, and then the nut 42 is threadedly engaged with the bolt 41 in the internal space of the column 1 until the nut 42 contacts and abuts against the inner side of the column 1. At this time, the connecting member 3 and the frame 2 can be fixed in position relative to the column 1; after multiple locking components 4 are assembled and installed, the four connecting members 3, the frame 2 and the column 1 can maintain a stable relative position.

[0047] Furthermore, in order to improve the positioning effect of the positioning member 23 on the position state of the frame 2 relative to the column 1 , preferably, among the plurality of locking components 4 , there are two locking components 4 located on both sides of the positioning member 23 .

[0048] The end of the positioning member 23 that is away from the corresponding connecting frame 22 is provided with a clearance groove 232 adapted to the nut 42. After the positioning member 23 is fully threaded with the clamping portion 211, the tail of the bolt 41 in the locking assembly 4 adjacent to the positioning member 23 will be close to the positioning member 23. After the nut 42 is fully threaded with the tail of the bolt 41, it will partially enter the clearance groove 232 and contact and abut against the groove wall of the clearance groove 232. At this time, the nut 42 will play a limiting role on the positioning member 23. In this embodiment, in order to improve the reliability and stability of the nut 42 playing a limiting role on the positioning member 23 at this time, it is preferred that the inner surface of the column 1 protrudes inward with a protrusion 13, and at this time, the nut 42 can contact and abut against the groove wall of the clearance groove 232 and the protrusion 13 at the same time.

[0049] Furthermore, in order to further improve the limiting effect of the nut 42 on the positioning member 23, and at the same time reduce the influence of the loosening of the positioning member 23 on the locking effect of the locking assembly 4, it is preferred that the rotation direction of the nut 42 and the tail thread of the bolt 41 is opposite to the rotation direction of the adjacent positioning member 23 and the clamping part 211.

[0050] At this time, when the positioning piece 23 tends to rotate loose relative to the clamping portion 211, this tendency will strengthen the locking effect of the adjacent locking assembly 4; at the same time, when the nut 42 in the locking assembly 4 tends to rotate loose relative to the tail of the bolt 41, this tendency will also strengthen the positioning effect of the adjacent positioning piece 23.

[0051] Reference Figure 1 and Figure 4 Furthermore, in order to facilitate construction personnel to fine-tune the position of the connecting member 3 relative to the frame body 2 according to needs after the connecting member 3 is positioned relative to the column 1 through multiple locking components 4, it is preferred that the frame body 2 is also equipped with multiple extension seats 26 and multiple adjustment members 27 on the top of the connecting frame 22. In this embodiment, it is preferred that four extension seats 26 and eight adjustment members 27 are installed on the top of the frame body 2, and the four extension seats 26 correspond to the four connecting frames 22 one by one, the extension seats 26 are fixedly connected to the connecting frame 22, and one extension seat 26 corresponds to two adjustment members 27; in this embodiment, it is preferred that the extension seat 26 is fixedly connected to the connecting frame 22 by welding, and the extension seat 26 is fixedly connected to the connecting frame 22 after the connecting member 3 is assembled and installed on the frame body 2.

[0052] After the extension seat 26 is fixedly installed on the top of the connecting frame 22, it can cover the top openings of the two corresponding matching grooves 221; the two adjusting members 27 are respectively installed on the extension seat 26 near the two matching grooves 221, and the adjusting members 27 are threadedly matched with the extension seat 26. By rotating the adjusting members 27, the movement of the adjusting members 27 relative to the extension seat 26 can be controlled, and the movement direction of the adjusting members 27 is parallel to the direction of the required position adjustment of the connecting member 3.

[0053] During the process of fine-tuning the position of the connecting member 3 relative to the frame 2 by controlling the adjusting member 27, one end of the adjusting member 27 is located in the corresponding matching groove 221 and contacts and abuts against the top of the corresponding matching portion 31 on the connecting member 3, and the other end of the adjusting member 27 is located above the extension seat 26 and has a structure that is convenient for construction personnel to control its rotation.

[0054] Furthermore, in order to enable construction personnel to enhance the relative position stability between the connecting member 3 and the column 1 while fine-tuning the position of the connecting member 3 downward, it is preferred that the surface of the side of the mating portion 31 on the connecting member 3 facing away from the column 1 is an inclined surface, and the corresponding mating groove 221 of the connecting frame 22 and the groove wall opposite to the column 1 are also inclined surfaces, and the two inclined surfaces are adapted to each other and can fit against each other.

[0055] At this time, during the process of fine-tuning the downward position of the connecting member 3 relative to the frame 2, the connecting member 3 will fit more closely with the surface of the column 1, and the force exerted on the frame 2 by the connecting member 3 will also be enhanced, thereby further improving the positional stability among the connecting member 3, the frame 2 and the column 1.

[0056] Furthermore, in order to reduce the probability of damaging the surface of the column 1 during fine-tuning of the position of the connecting member 3, the connecting member 3 is preferably provided with an elastic protective layer 32 fixedly installed on one side thereof that is in contact with the surface of the column 1. In this embodiment, the protective layer 32 is preferably made of rubber material.

[0057] The implementation principle of the prefabricated building component connection structure in the embodiment of the present application is: After the construction of the column 1 is completed, the frame 2 is first assembled on the top of the column 1 by hoisting, so that the four clamping parts 211 of the frame 2 are respectively clamped with the four clamping grooves 11 on the column 1, and the frame 2 is controlled to move to the desired position relative to the column 1, and the positioning member 23 is controlled to be completely threaded with the clamping part 211, so that the relative position of the frame 2 on the column 1 is fixed; Then, the limit piece 25 is installed at the bottom of the frame 2, and the four connecting pieces 3 are assembled and installed on the four sides of the column 1 with the help of the frame 2 by hanging, so that the two matching parts 31 of the connecting piece 3 are both inserted into the two adjacent matching grooves 221 on the frame 2, and the connecting piece 3 is kept in contact with the surface of the column 1; then, the connecting piece 3 is fixed with the frame 2 and the column 1 at the same time through multiple locking components 4, and then multiple extension seats 26 and multiple adjustment pieces 27 are installed on the top of the frame 2, and then the adjustment pieces 27 are controlled to rotate according to needs to drive the connecting piece 3 to move downward for fine-tuning the position, and then the four connecting pieces 3 can be assembled and installed between the four beams and the column 1.
