Description

Technical Field

[0001] The utility model belongs to the technical field of assembled buildings, and in particular relates to an energy dissipation and shock absorption assembled frame combined structure node. Background Art

[0002] Incorporating energy-dissipating and vibration-absorbing components into the structural joints of prefabricated buildings can absorb and dissipate a significant portion of earthquake energy, effectively reducing damage to the building itself. Viscoelastic dampers are simple, readily available, and offer excellent performance, making them suitable for wind and earthquake resistance in high-rise structures. However, their limited energy absorption and dissipation make them less effective in controlling seismic responses.

[0003] CN211621950U discloses an energy dissipation and shock absorption node for assembled concrete frame structures, which belongs to the fields of building structure technology and structural shock absorption. The node is a hinged node, which consists of a connecting steel plate, a pin and a pad. The connecting steel plate can rotate with the pin as the center of the circle to increase the deformation capacity of the node. Polytetrafluoroethylene is arranged between the pad and the steel plate to prevent the node from being damaged by friction. Energy dissipation and shock absorption devices are installed above and below the pin. Metal rubber is the main shock absorption component. The metal rubber is placed in a bushing. An extrusion plate is provided on the beam. Part of the energy generated by the earthquake can be consumed by squeezing the metal rubber through the extrusion plate and the friction between the metal rubber and the bushing.

[0004] However, when an earthquake occurs, the prefabricated structure nodes are subjected to both longitudinal and lateral external forces. The above technical solution is difficult to eliminate the lateral external forces on the nodes, which may cause the nodes to be damaged and affect the safe use of the frame structure. Utility Model Content

[0005] The purpose of the utility model is to provide an energy dissipation and shock absorption assembled frame combined structure node to solve the above-mentioned existing technical problems.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A node of an energy dissipation and shock absorption assembled frame composite structure includes a column and a beam, and further includes: a connecting piece, one end of which is arranged on the side surface of the column and the other end is connected to the beam; a first energy dissipation and shock absorption component, including: a first mounting plate, which is respectively arranged at the bottom of the beam and the side surface of the adjacent column; a first tube body, one end of which is arranged on the first mounting plate and provided with a first tube cavity; a rod body, one end of which is arranged on the first mounting plate not provided with the first tube body and the other end extends into the first tube cavity; a first clamping ring, which is provided in the first tube cavity and is at the end of the first tube body not extended into by the rod body; the end of the rod body not provided on the first mounting plate is connected to or slightly spaced from the first clamping ring.

[0008] Furthermore, the inner diameter of the first lumen may be slightly larger than the diameter of the rod body.

[0009] Furthermore, the length of the rod body is smaller than the length of the first tube body; and the first tube body is arranged at an angle.

[0010] Furthermore, a plurality of the first clamping rings are provided and are distributed at intervals along the length direction of the first lumen; and the ring diameter of each of the first clamping rings decreases in sequence.

[0011] Furthermore, the first energy dissipation and shock absorption assembly further includes: a shock absorbing pad, which is arranged in the first tube body near one end of the first mounting plate; the area of the shock absorbing pad is larger than the cross-sectional area of the first tube body.

[0012] Furthermore, the structural node also includes: a second energy dissipation and shock absorption assembly, including: a second mounting plate, which is respectively arranged on two adjacent side surfaces of the two beams; a left rod, one end of which is arranged on the second mounting plate; a second tube body, which is provided with a second tube cavity; the end of the left rod not close to the second mounting plate extends into the second tube cavity; a second elastomer, which is arranged in the second tube cavity and is located in front of the end of the left rod; a second clamping ring, which is arranged in the second tube cavity; the second clamping ring is located between the second elastomer and the left rod.

[0013] Furthermore, the second energy dissipation and shock absorption assembly also includes: a right rod, one end of which is arranged on another second mounting plate that is not provided with the left rod, and the other end extends into the second tube cavity; the second clamping ring and the second elastomer are sequentially arranged in front of the end of the right rod.

[0014] Furthermore, the second clamping ring in front of the end of the left rod is provided on the right rod; and the second clamping ring in front of the end of the right rod is provided on the left rod.

[0015] Furthermore, the lengths of the left rod and the right rod are smaller than the length of the second tube body; and the second tube body is arranged obliquely.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. When vibration occurs, the rod of the first energy dissipation and shock absorption assembly will move in the first tube cavity, move relative to the first elastic body, and dissipate energy due to the restriction of the first clamping ring; when the vibration increases, the rod will move forward to break through the first clamping ring, and energy will be consumed in the process of breaking through the first clamping ring, thereby achieving energy dissipation of the longitudinal vibration; the multiple first clamping rings arranged in the first tube cavity can improve the energy dissipation effect; combined with the shock-absorbing pad arranged on the first mounting plate, the shock absorption effect can be improved.

[0018] 2. When an earthquake occurs, the beam of the second energy dissipation and shock absorption component may vibrate in the horizontal direction. At this time, the vibration conduction will push the left rod and the right rod to move in the second tube cavity respectively, and then squeeze the second clamping ring and the second elastic body, thereby dissipating energy and reducing shock.

[0019] By combining the first energy dissipation and shock absorption component and the second energy dissipation and shock absorption component, the longitudinal and transverse vibrations generated by the beam during an earthquake are dissipated, the damage caused by the vibration to the nodes is reduced, and the safety of the building is ensured.

DETAILED DESCRIPTION

[0029] In order to facilitate a better understanding of the present invention, the following examples are used to illustrate the present invention in conjunction with the accompanying drawings. These examples belong to the protection scope of the present invention, but do not limit the protection scope of the present invention.

[0030] Example 1

[0031] An energy dissipation and shock absorption assembled frame composite structure node, such as Figure 1-Figure 3 、 Figure 7 As shown, it includes a column 1, a beam 2, and also includes: a connecting member 3, one end of which is arranged on the side of the column 1, and the other end is connected to the beam 2; a first energy dissipation and shock absorption component 4, including: a first mounting plate 41, which is respectively arranged at the bottom of the beam 2 and the side of the adjacent column 1; a first tube body 42, one end of which is arranged on the first mounting plate 41, and a first tube cavity 421 is provided therein; a rod body 43, one end of which is arranged on the first mounting plate 41 not provided with the first tube body 42, and the other end extends into the first tube cavity 421; a first clamping ring 44 is provided in the first tube cavity 421, and is at one end of the first tube body 42 not extended into by the rod body 43; the end of the rod body 43 not provided on the first mounting plate 41 is connected to or slightly spaced from the first clamping ring 44.

[0032] The column can be a square tube with concrete poured inside; the four sides of the column can be provided with a suitable number of connectors as needed; the connectors can be made of channel steel, and the connectors can be welded to the column.

[0033] The crossbeam 21 is a concrete beam with an I-beam 21 embedded in its end for connection to the connector 3. Rivets are provided on the length of the I-beam. The connector is provided on the side of the I-beam web, and the sides of the two fit together. The connector and the I-beam can be connected by high-strength bolts. After the node connection is completed, concrete is poured.

[0034] The first mounting plate can be fixed to the column and the beam by using bolts, so that if it is damaged, it can be replaced and installed in time.

[0035] like Figure 2-Figure 3 As shown, a first elastic body 46 is provided on the inner wall of the first tube body 42. When the rod moves in the first tube cavity, it moves with the first elastic body to dissipate energy. The first elastic body is an existing viscoelastic material.

[0036] When an earthquake occurs, the assembled structural nodes are easily damaged because they are the connection points between beams and columns, which in turn endangers the safety of the building; when vibration occurs, the first energy dissipation and shock absorption rod will move in the first tube cavity, move relative to the first elastic body, and the end will rest on the first clamping ring, thereby dissipating energy; when the vibration increases, the rod can move forward to break through the first clamping ring, thereby dissipating the energy of the longitudinal vibration; multiple first clamping rings set in the first tube cavity can improve the energy dissipation effect.

[0037] After an earthquake occurs, the damage to each component of the first energy dissipation and shock absorption assembly should be checked in time. If damaged, the entire assembly can be dismantled and replaced.

[0038] Example 2

[0039] like Figure 1-Figure 3 As shown, the inner diameter of the first lumen 421 may be slightly larger than the diameter of the rod body 43 .

[0040] like Figure 1-Figure 3 As shown, the length of the rod body 43 is smaller than the length of the first tube body 42; the first tube body 42 is arranged obliquely.

[0041] like Figure 1-Figure 3 As shown, there are a plurality of first clamping rings 44 , which are spaced apart and distributed along the length direction of the first lumen 421 ; the ring diameters of the first clamping rings 44 decrease in sequence.

[0042] like Figure 1-Figure 3 As shown, the first energy dissipation and shock absorption assembly 4 further includes: a shock absorbing pad 45 , which is disposed in the first tube body 42 near one end of the first mounting plate 41 ; the area of the shock absorbing pad 45 is larger than the cross-sectional area of the first tube body 42 .

[0043] The inner diameter of the first lumen is slightly larger than that of the rod body, so that the rod body can move inside the lumen when it is vibrated.

[0044] There are several first clamping rings, and the inner diameter gradually decreases along the length direction of the first tubular cavity, so that the rod body encounters the first clamping ring when moving downward. If the impact force of the vibration is large, the rod body can break through the first clamping ring. Since the ring diameter of the first clamping ring gradually increases, the force required for the rod body to break through will become greater, thereby playing the role of energy dissipation and shock reduction.

[0045] The provided shock-absorbing pad can be made of elastic material and is used to eliminate the external force exerted on the beam during vibration; it can be made of elastic rubber and other materials and can be fixed to the first mounting plate with fasteners such as screws.

[0046] The first clamping ring may also adopt an internal conical structure, with one end being larger than the other end, that is, the end close to the rod body is slightly larger and then gradually decreases.

[0047] Example 3

[0048] like Figure 1 、 Figure 4-Figure 6As shown, the structural node also includes: a second energy dissipation and shock absorption component 5, including: a second mounting plate 51, which is respectively arranged on two adjacent side surfaces of the two beams 2; a left rod 52, one end of which is arranged on the second mounting plate 51; a second tube body 53, which is provided with a second tube cavity 531; the end of the left rod 52 not close to the second mounting plate 51 extends into the second tube cavity 531; a second elastic body 54, which is arranged in the second tube cavity 531 and is located in front of the end of the left rod 52; a second clamping ring 55, which is arranged in the second tube cavity 531; the second clamping ring 55 is located between the second elastic body 54 and the left rod 52.

[0049] like Figure 4-Figure 6 As shown, the second energy dissipation and shock absorption assembly 5 also includes: a right rod 56, one end of which is arranged on another second mounting plate 51 without the left rod 52, and the other end extends into the second tube cavity 531; the front end of the right rod 56 is provided with a second clamping ring 55 and a second elastomer 54 arranged in the second tube cavity in sequence.

[0050] like Figure 4-Figure 6 As shown, a partition 57 is provided between the left rod 52 and the right rod 56; the side surface of the partition 57 is connected to the inner wall of the second tube body 53; the partition 57 divides the second tube cavity 531 into two left and right tube cavities, so that the left rod is in the left tube cavity and the right rod is in the right tube cavity; the outer areas of the left rod and the right rod have third elastomers 58 respectively provided on the inner wall of the second tube body 53 and the side surface of the partition 57; the third elastomer is an existing viscoelastic material.

[0051] The partition is combined with the inner wall of the second tube body to fix the second clamping ring, and the third elastic body can play the role of energy dissipation and shock absorption when the left rod and the right rod move.

[0052] like Figure 4-Figure 6 As shown, the second snap ring 55 in front of the end of the left rod 52 is provided on the right rod 56 ; the second snap ring 55 in front of the end of the right rod 56 is provided on the left rod 52 .

[0053] like Figure 4-Figure 6 As shown, the lengths of the left rod 52 and the right rod 56 are smaller than the length of the second tube 53; the second tube 53 is arranged obliquely.

[0054] The second mounting plate can be fixed to the beam with bolts, so that it can be replaced and installed in time if it is damaged. Since the beam is a concrete beam, the bolts can be pre-buried in appropriate positions in the concrete beam. Screw holes are opened at corresponding positions of the second mounting plate, and the second mounting plate can be fixed to the side of the beam through threaded connection between the nut and the bolt.

[0055] The second elastic body can be made of elastic material and used to eliminate the external force on the beam during vibration; it can be made of elastic rubber and other materials and can be fixed to the second mounting plate with fasteners such as screws.

[0056] The two ends of the second mounting plate are fixed on both sides of the crossbeam and the connecting piece, and the connection between the web of the crossbeam and the connecting piece can be fixed by fasteners such as bolts; Figure 1 As shown, in order to fix the second mounting plate, one end of a fastener such as a bolt can be welded to the connecting piece, and the other end can pass through the second mounting plate and then be fixed by tightening it with a nut. When replacing, the second energy dissipation and shock absorption assembly can be removed and replaced by removing the nut.

[0057] During an earthquake, the beam is also subject to horizontal forces. Therefore, a second energy dissipation and shock absorption assembly is provided to dissipate these lateral forces. A second retaining ring is provided on each end of the left and right rods, near the ends. This allows them to move and abut against the second retaining ring when a vibration occurs. When the left and right rods move relative to each other, the forces acting on them oppose each other, dissipating the vibration force through relative movement. A second elastic body, made of an elastic material, provides a shock-absorbing effect.

[0058] After an earthquake occurs, the damage to each component of the second energy dissipation and shock absorption assembly should be checked in time. If damaged, the entire assembly can be dismantled and replaced.

[0059] During specific use, the first energy dissipation and shock absorption assembly and / or the second energy dissipation and shock absorption assembly may be used between the crossbeam and the column, and between the crossbeams.

[0060] When pouring concrete on the crossbeam, bolts can be pre-embedded to connect and fix the first mounting plate and the second mounting plate, and then tightened and fixed with nuts; this also makes it easy to disassemble and replace the first mounting plate and the second mounting plate when needed.
