Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building, in particular to a self-resetting energy dissipation hinge beam-column connection node and an assembling method. BACKGROUND

[0002] In recent years, fabricated buildings have become an important direction to realize green buildings and industrialization due to their short construction period, small environmental impact, and easy quality control. Among them, the fabricated concrete frame structure is one of the most common and widely used fabricated structure systems. The fabricated concrete frame can be divided into dry connection and wet connection modes according to the connection mode of the node. The dry connection form refers to the connection of the node by pre-burying connecting pieces in the components without pouring concrete. Due to the non-integral pouring mode of the node, the overall performance of the fabricated frame structure is poorer and the seismic performance is insufficient compared with the cast-in-place frame structure. This problem has always restricted the development and promotion of fabricated buildings. With the improvement of dry connection methods and technologies, such as sleeve grouting connection, restrained grout anchor connection, and post-pouring strip connection, these methods have gradually matured and are widely used.

[0003] However, in the existing node connection form, although the cast-in-place structure can ensure that the node has sufficient strength, stiffness, and good energy dissipation capacity, a large amount of concrete wet work is still required on the construction site, which cannot meet the green, energy-saving, and efficient development concept of fabricated buildings. The node formed by sleeve grouting connection and grout anchor lap joint has similar performance to the cast-in-place structure, but it is difficult to meet the demand in terms of energy dissipation capacity and damage control.

[0018] S2, hingedly connecting the two ends of the connecting steel plate with the column connecting block and the beam connecting block respectively;

[0019] S3, installing the energy dissipation self-resetting connecting block, pushing the energy dissipation self-resetting connecting block into the reserved installation position, bolt connecting the first connecting plate and the second connecting plate, and bolt connecting the third connecting plate and the conversion steel plate.

[0020] The application has the following advantages:

[0021] (1) The self-resetting energy dissipation hinge beam-column connecting joint provided by the application is a high-energy dissipation self-resetting beam-column joint, which can realize the self-resetting of the joint after the action of an earthquake, reduce residual deformation, and facilitate the replacement of damaged components. In the application, the joint can dissipate energy in the horizontal direction through the energy dissipation self-resetting connecting block. The beam connecting block and the column connecting block are hingedly connected with the connecting steel plate through a pin shaft, forming a multi-section connecting mechanical hinge, which further improves the energy dissipation capacity of the joint in other directions.

[0022] (2) In the application, the beam connecting block and the column connecting block are fixedly installed through the pre-embedded steel part embedded in the concrete, thereby enhancing the anchoring between the steel components and the concrete.

[0023] (3) The setting of the guide rod inside the energy dissipation self-resetting connecting block can prevent the deformation of the self-resetting spring out of the plane. The through hole on the special-shaped plate allows the guide rod to have a certain space for movement when the structure deforms, thereby not limiting the deformation of the self-resetting spring. The self-resetting spring should have a certain tension when installed, so that it can offset the axial force transmitted by the structure during normal use. The deformation of the structure under the action of an earthquake causes the spring to deform further, thereby providing a reverse force to resist deformation. The energy dissipation steel plate is in a wave shape, which can dissipate energy during an earthquake and is not easy to break. In the present application, the through hole is in the form of a strip hole, which is conducive to the fitting of the guide rod and the through hole, and avoids hindering the translational movement of the guide rod.

[0024] (4) In the present application, the steel hinge plate is formed by symmetrically arranging two L-shaped plates, and a gap is formed between the two L-shaped plates to avoid hindering the rotation of the connecting steel plate. The middle part of the two vertical edges of the end plate is provided with a notch. When the energy dissipation self-resetting connecting block is installed on the column connecting block and the beam connecting block, the notch is located on the rotation track of the end part of the connecting steel plate, and the steel hinge plate with a double L-shaped plate is reserved for rotation control of the connecting steel plate, so as to give the connecting steel plate a certain space for movement when the node is subjected to tension and compression, thereby reducing the probability of node damage.

[0025] (5) In the present application, the first connecting plate, the second connecting plate and the third connecting plate are arranged to make the energy dissipation self-resetting connecting block respectively face and fit the conversion steel plate and the steel hinge plate, thereby improving the stability of the structure and improving the overall performance.

[0026] (6) The present application also provides an assembling method of the self-resetting energy dissipation hinge beam column connecting node, which can quickly and conveniently connect the vertical column and the horizontal beam through the above-mentioned self-resetting energy dissipation hinge beam column connecting node to realize energy dissipation in the building. The energy dissipation structure, i.e. the energy dissipation self-resetting connecting block, in the self-resetting energy dissipation hinge beam column connecting node is detachably connected by bolts, which facilitates the replacement of the energy dissipation self-resetting connecting block. In the present application, the embedded steel part can be integrally formed with the connected column connecting block or beam connecting block, thereby further improving the anchoring property of the concrete and the steel member.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] As shown in Figures 1-8 , the self-resetting energy dissipation hinge beam-column connecting joint proposed in the embodiment includes a column connecting block 3, a beam connecting block 4, a connecting steel plate 6, and two energy dissipation self-resetting connecting blocks 5.

[0038] As shown in Figure 2 , in the embodiment, the column connecting block 3 and the beam connecting block 4 adopt the same structure of connecting block, which includes an embedded steel part 31, a conversion steel plate 32, a steel hinge plate 33, and a second connecting plate 35.

[0039] The embedded steel part 31 and the steel hinge plate 33 are arranged on both sides of the conversion steel plate 32, and two opposite second connecting plates 35 are further arranged on the conversion steel plate 32, the second connecting plates 35 are located on the same side of the conversion steel plate 32 as the steel hinge plate 33, and the two second connecting plates 35 are used to connect the energy dissipation self-resetting connecting blocks 5.

[0040] The embedded steel part 31 is used for embedding in the concrete to improve the anchoring performance of the connecting block and the concrete. The connecting block as a whole can adopt an integrated structure to improve the internal stress and avoid the possibility of structural fracture. The embedded steel part 31 can specifically adopt an I-shaped steel part to improve the connection area of the embedded steel part and the conversion steel plate 32. In specific implementation, longitudinal reinforcement 12 can also be reserved on the concrete to further improve the anchoring performance through the welding of the longitudinal reinforcement 12 and the conversion steel plate 32.

[0041] The steel hinge plate 33 is composed of two symmetrically arranged L-shaped plates, the short plates of the L-shaped plates serving as third connecting plates 34, the third connecting plates 34 extending outward to connect the energy dissipation self-resetting connecting blocks 5 through the third connecting plates 34. The long plates of the L-shaped plates are close to each other, i.e., located between the two third connecting plates 34, and the long plates of the L-shaped plates are provided with round holes for pin shaft hinging of the connecting steel plates 6 clamped between the two long plates. The middle part of the two vertical edges of the end plate 53 is provided with a notch 56, when the energy dissipation self-resetting connecting blocks 5 are installed on the column connecting block 3 and the beam connecting block 4, the notch 56 of the first energy dissipation self-resetting connecting block 5 is located on the concentric circle of the rotation track of the upper end of the connecting steel plate 6, and the notch 56 of the second energy dissipation self-resetting connecting block 5 is located on the concentric circle of the rotation track of the lower end of the connecting steel plate 6, so as to give the connecting steel plate 6 a certain space for movement and reduce the probability of node damage.

[0042] In this way, the first end of the connecting steel plate 6 is inserted between the long plates of the two L-shaped plates of the column connecting block 3, and the first end of the connecting steel plate 6 is hinged with the long plates of the L-shaped plates of the column connecting block 3; the second end of the connecting steel plate 6 is inserted between the long plates of the two L-shaped plates of the beam connecting block 4, and the second end of the connecting steel plate 6 is hinged with the long plates of the L-shaped plates of the beam connecting block 4; thereby realizing multi-segment mechanical hinging through the two ends of the connecting steel plate 6 hinged with the column connecting block 3 and the beam connecting block 4 respectively, and realizing multi-directional energy dissipation. The steel hinge plate 33 of the column connecting block 3 is located above the steel hinge plate of the beam connecting block 4.

[0043] In specific implementation, the column connecting block 3 is embedded in the column 2 through the embedded steel part 31, the beam connecting block 4 is embedded in the beam through the embedded steel part, and then the detachable connection of the column connecting block 3 and the beam connecting block 4 is realized through the energy dissipation self-resetting connecting block 5, so as to realize the connection of the beam 1 and the column 2.

[0044] As shown in Figure 3 , Figure 4 , Figure 5 , the energy dissipation self-resetting connecting block 5 includes a self-resetting spring 51, a special-shaped plate 52, an end plate 53, a guide rod 54, and an energy dissipation steel plate 55.

The special-shaped plate 52 is connected with the conversion steel plate 32 of the column connecting block 3, and the special-shaped plate 52 is provided with a through hole 522 located in the extension direction of the guide rod 54; the special-shaped plate 52 cooperates with the conversion steel plate 32 to form a cavity communicating with the through hole 522, so that the guide rod 54 can displace to the cavity through the through hole 522. In this way, when the energy dissipation self-resetting connecting block 5 deforms, the guide rod 54 can displace towards the through hole 522, ensuring the deformation space allowance of the self-resetting spring 51. In the embodiment, the length of the guide rod 54 is not less than the original length of the self-resetting spring 51, so that the deformation direction of the self-resetting spring 51 can be constrained, thereby avoiding damage and deformation of the self-resetting spring 51 in the non-stretching direction, and ensuring the energy dissipation reliability and self-resetting ability of the energy dissipation self-resetting connecting block 5.

[0046] In the embodiment, the through hole 522 on the special-shaped plate 52 is a strip-shaped hole, which ensures smooth translation of the guide rod 54, and the guide rod 54 is a steel member, which ensures structural stability.

[0047] In the embodiment, the end plate 53 is provided with two guide rods 54 with central axes located on the same horizontal plane, and one self-resetting spring 51 is sleeved on each guide rod 54. Four energy dissipation steel plates 55 are arranged between the end plate 53 and the special-shaped plate 52, two of which are located above the two self-resetting springs 51, and the other two are located below the two self-resetting springs 51.

[0048] In the embodiment, the first energy dissipation self-resetting connecting block 5 is arranged between the column connecting block 3 and the beam 1, and the second energy dissipation self-resetting connecting block 5 is arranged between the beam connecting block 4 and the column 2.

The end plate 53 of the second energy dissipation self-resetting connecting block 5 is connected with the third connecting plate of the beam connecting block 4, and the special-shaped plate 52 of the second energy dissipation self-resetting connecting block 5 is connected with the conversion steel plate 32 of the column connecting block 3.

[0050] Specifically, the special-shaped plate 52 is composed of a plane plate and two first connecting plates 523, and the two first connecting plates 523 are arranged on the plane plate and perpendicular to the plane plate, and the plane plate and the two first connecting plates 523 form a right-angle U-shaped structure. A stiffening rib 521 connecting the plane plate is arranged between the two first connecting plates 523, which facilitates better transmission of axial force and prevents deformation of the special-shaped plate.

[0051] The second connecting plate 35 on the column connecting block 3 is respectively attached to and bolted with two first connecting plates 523 in the special-shaped plate 52 of the second energy dissipation self-resetting connecting block 5, and the third connecting plate 34 on the beam connecting block 4 is attached to and bolted with the end plate 53 of the second energy dissipation self-resetting connecting block 5.
