Description

Technical Field

[0001] The present invention relates to the technical field of building beam-column node equipment, in particular to an assembled beam-column node structure. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. 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. However, when connecting the beams and columns of prefabricated buildings, most of them use beam-column node structures to improve the installation efficiency of prefabricated buildings.

[0003] After searching, the Chinese utility model patent with authorization announcement number "CN218580878U" discloses "an assembled building beam-column node structure". This application can not only install two sets of first connection components through the setting of positioning components, but also enable the two sets of first connection components to engage and limit the second connection components and the diagonal bracing components, so that the specifications of the node can be expanded by connection, thereby achieving the effect of rapid assembly when facing building beams and columns of different specifications.

[0004] When the above-mentioned device is actually used, the specifications of the actual node are expanded by overlapping and connecting with each other, so as to adapt to different building beams and columns. The actual stability generally depends on the actual connection relationship between the connecting parts. In addition, the overlapping and connecting method of multiple positioning components reduces the actual installation efficiency to a certain extent. For this reason, the applicant proposes a new type of prefabricated beam-column node structure. Summary of the Invention

[0028] A self-tapping screw is installed between a right-angle surface of the right-angle bent plate and the carrying box, and the self-tapping screw penetrates the surface and then screws into the top of the carrying box;

[0029] A reinforcing bolt is installed at a right angle to the other right-angle surface of the right-angle bent plate and the outer surface of the beam column. The reinforcing bolt penetrates the surface and then is screwed into the interior of the beam column.

[0035] The threads of the two screws are turned in opposite directions, and one end of the two screws is hinged to the two ends of the inside of the carrying box, and the other ends of the two screws are respectively fixed with linkage gears;

[0036] Two linkage gears are respectively placed at the two ends of the gear box, and both linkage gears are meshed with the transmission bevel gear;

[0037] The interior of the sliding block is provided with screw holes running through both sides thereof, and the screw holes are adapted to the screw rods.

[0045] Moreover, compared with the method of expanding its own scale by stacking, this application reduces the actual operation workload of the staff and improves the installation efficiency of the node structure to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0053] 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. However, when connecting the beams and columns of prefabricated buildings, most of them use beam-column node structures. Different building beams and columns require node structures of different specifications. In order to adapt to different building beams and columns, the applicant proposes a new structure with adjustable node structure specifications to improve actual installation efficiency.

[0054] Among them reference Figure 1 - Figure 5 It can be seen that

[0055] The assembled beam-column node structures are provided with at least two groups, and the two groups of assembled beam-column node structures are respectively fitted on two opposite surfaces of the outer surface of the beam-column;

[0056] The prefabricated beam-column node structure includes:

[0057] The adjustment assembly 1 includes: a carrier box 101, a top of which is formed with an inspection port for maintenance, and a bottom of which is formed with a communication gap 106;

[0058] Sliding blocks 107 are placed at both ends of the carrying box 101, and the sliding blocks 107 and the carrying box 101 are in a sliding connection relationship; and

[0059] A driving component, which is fixed to the middle end of the interior of the carrier box 101 via an access port and is used to move the two sliding blocks 107 toward each other;

[0060] Mounting parts 104 for sealing the maintenance opening are respectively installed at both ends of the top of the carrier box 101;

[0061] A connecting column that matches the communicating notch 106 is fixed to the bottom of the sliding block 107, and a reinforcing component 2 is fixed to the bottom ends of the two connecting columns:

[0062] Reinforcement component 2 includes:

[0063] The connecting arm 204 is in a horizontal "L" structure;

[0064] There are two connecting arms 204;

[0065] The shorter ends of the two connecting arms 204 are fixed to the connecting column, and the other ends of the two connecting arms 204 are arranged to face each other;

[0066] The bottom of the two connecting arms 204 is respectively fixed with an assembly plate 201 with a mounting notch 207 formed at the bottom of the outer surface. The two sets of assembled beam-column node structures are installed with a cross column 4 passing through the interior of the beam and column by means of the mounting notch 207 in the assembly plate 201.

[0067] It should be emphasized that, by installing a driving component that enables the two sliding blocks 107 to move toward each other in the carrier box 101, and fixing the reinforcement components 2 that can be fixed to the inside of the beam and column at the bottom of the two sliding blocks 107, the present application realizes that when the device is actually used, it can not only expand the actual scale of its own structure without stacking, thereby adapting to different beams and columns,

[0068] Moreover, compared with the method of expanding its own scale by stacking, this application reduces the actual operation workload of the staff and improves the installation efficiency of the node structure to a certain extent.

[0069] Example 1

[0070] refer to Figure 2 and Figure 3 It can be seen that in this application,

[0071] A telescopic rod 203 is fixed between two assembly plates 201 in a set of assembled beam-column node structures;

[0072] The telescopic rod 203 is used to strengthen the connection between the two assembly plates 201 .

[0073] When there are four groups of prefabricated beam-column node structures, the beams and columns are rectangular columns.

[0074] At this time, the four sets of assembled beam-column node structures are respectively fitted on the four outer surfaces of the beams and columns;

[0075] The heights of the mounting gaps 207 provided in two groups of relatively arranged prefabricated beam-column node structures are much lower than those of the other two groups.

[0078] A fitting block 205 is fixed to the longer end of the connecting arm 204;

[0079] A connecting plate 202 is fixed to the bottom of the fitting block 205;

[0080] A locking bolt 206 is inserted and installed between two adjacent connecting plates 202 on two adjacent sides of the rectangular column;

[0081] After the end of the locking bolt 206 passes through the two connecting plates 202 in sequence, a locking nut is threadedly installed at the position of the connecting plate 202 closest to the end.

[0082] It should be emphasized that the appearance structure of the bonding block 205 in this application can be referred to Figure 5 By designing the fitting blocks 205 into a right triangle structure, the inclined ends of two adjacent fitting blocks 205 can be fitted together during actual assembly.

[0083] Example 3:

[0084] refer to Figure 4 It can be seen that in this application,

[0085] The mounting member 104 is a right-angle bent plate;

[0086] A self-tapping screw is installed between a right-angled surface of the right-angle bent plate and the carrier box 101. The self-tapping screw penetrates the surface and then screws into the top of the carrier box 101.

[0087] A reinforcing bolt 102 is installed at a right angle to the other right-angled surface of the right-angle bent plate and the outer surface of the beam column. The reinforcing bolt 102 penetrates the surface and then is screwed into the interior of the beam column.

[0088] It should be added that the mounting member 104 also improves the connection relationship between the node structure and the beam column to a certain extent.

[0089] Example 4:

[0090] refer to Figure 4 It can be seen that in this application,

[0091] The opposite ends of the two mounting members 104 are respectively fitted with the exterior of the driving component;

[0092] The drive components include:

[0093] The gear box 103 is fixed inside the carrier box 101 via an access port;

[0094] The bottom end of the gear box 103 is rotatably connected to a transmission bevel gear 109. A shaft-loaded handle 108 is fixed inside the transmission bevel gear 109 and passes through the gear box 103 and the bottom of the carrier box 101 in sequence. The handle end of the shaft-loaded handle 108 is placed at the bottom end of the outside of the carrier box 101.

[0095] Rotatable screws 105 are inserted into both ends of the gear box 103;

[0096] The threads of the two screw rods 105 are turned in opposite directions, and one end of the two screw rods 105 is hinged to the two ends of the interior of the carrier box 101, and the other end of the two screw rods 105 is fixed with a linkage gear 110;

[0097] Two linkage gears 110 are respectively placed at both ends of the gear box 103, and both linkage gears 110 are meshed with the transmission bevel gear 109;

[0098] The sliding block 107 is provided with screw holes running through both sides thereof, and the screw holes are adapted to fit the screw rods 105 .

[0099] Slide rails 111 are fixed at both ends of the interior of the carrying box 101;

[0100] One end of the two slide rails 111 is fixed to the two ends of the interior of the carrier box 101, and the other end of the two slide rails 111 is fixed to the bottom of the two ends of the exterior of the gear box 103;

[0101] A contact groove is formed at the bottom of the sliding block 107 , and the contact groove is adapted to the sliding rail 111 .

[0102] It should be noted that when the device is actually used, the belt shaft force handle 108 is manually subjected to force. When the belt shaft force handle 108 is forced to rotate, the shaft end of the belt shaft force handle 108 drives the transmission bevel gear 109 to rotate. When the transmission bevel gear 109 rotates, the two interlocking gears 110 meshing with it rotate. When the two interlocking gears 110 rotate, the screw 105 rotates, and with the help of the different steering threads on the outside of the screw 105, the two sliding blocks 107 move toward each other, and finally the connecting arms 204 at the bottom of the two sliding blocks 107 move toward each other.

[0103] When adjusted to the appropriate position, stop applying force to the shaft force handle 108. Since the thread on the screw rod 105 is based on the locking feature, the sliding block 107 will not move unless it touches the shaft force handle 108. At this time, the cross column 4 between the two node structures on the opposite sides is outer-mounted with the fastening nut 3 connected to the structure to realize the actual installation of the device.

[0104] Example 5

[0106] A rotatable sealing cover is installed on the top of the gear box 103.

[0107] A liquid injection valve tube connected to the interior of the gear box 103 is fixed on the top of the sealing cover.

[0108] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is limited by the accompanying embodiments and their equivalents.
