Description

Technical Field

[0001] The utility model belongs to the field of assembled buildings, and in particular relates to a beam-column node and a house structure system. Background Art

[0002] The centrifugal process is a mature technology for producing prefabricated pipe piles and can also be used to produce hollow columns. However, when using the centrifugal process to produce columns, since the columns require connection nodes at the floor level, if the connection nodes protrude from the column, it will cause significant difficulties in standardizing the column mold.

[0003] Therefore, how to achieve standardized production of hollow columns through node solutions and the subsequent installation of node parts has become an urgent problem that needs to be solved. Utility Model Content

[0004] One purpose of the utility model is to provide a beam-column joint that realizes the standardized production of hollow columns;

[0005] The second purpose is to achieve standardized production of hollow columns for application in prefabricated house structures.

[0006] To this end, the present invention primarily provides a beam-column joint, characterized in that it includes:

[0007] A precast hollow concrete column having a steel node section;

[0008] A hoop assembly, the hoop assembly comprising at least two hoops, the two hoops being mounted on both sides of the steel node section of the precast hollow concrete column by enclosing or pulling against each other;

[0009] A prefabricated corbel is installed and connected to the clamp.

[0010] Preferably, the two clamps are installed on the precast hollow concrete column by means of a tension assembly; the tension assembly includes an upper tension rod group and a lower tension rod group, the upper tension rod group passes through the precast hollow concrete column and the two ends are tensioned at the top position of the two clamps, the lower tension rod group passes through the precast hollow concrete column and the two ends are tensioned at the bottom position of the two clamps.

[0011] Preferably, the prefabricated corbel is connected to the hoop and is located between the top and bottom positions of the hoop.

[0012] Preferably, the prefabricated corbel is a prefabricated box, one side of the box is shaped to fit the clamp, and the other side forms a stepped overlap interface for overlapping and installing prefabricated beams.

[0013] Preferably, ear plates are formed at both ends of the two hoops, the two hoops enclose the steel node segment and the ear plates are positioned correspondingly; the prefabricated corbels are hinged to the ear plates.

[0014] Preferably, the prefabricated corbel is an H-shaped steel, and the web of the H-shaped steel is clamped between the ear plates of the two clamps and fastened and installed by bolts.

[0015] Preferably, a shear key is formed on the side of the hoop facing the precast hollow concrete column; a supporting groove corresponding to the position of the shear key is formed on the side surface of the precast hollow concrete column.

[0016] Preferably, a slot is formed at the edge of the supporting groove, and a cam is formed at the edge of the shear key; the cam is locked in the slot and forms a limit in at least the tensile direction of the precast corbel and the precast hollow concrete column.

[0017] Preferably, the locking slot is a beveled slot, and the locking protrusion has a wedging beveled edge corresponding to the beveled slot.

[0018] The technical effects of the above technical solution of the utility model come from one or more of the following combinations:

[0019] Prefabricated hollow concrete columns do not require protruding corbels during factory production, making the production of centrifugal columns convenient and transportation does not take up a large space due to protruding nodes.

[0020] The protruding prefabricated corbels are fixed to the prefabricated hollow concrete columns by means of supporting grooves and shear keys for shear resistance and bolts for tension resistance. The outward extension nodes of the columns can be realized without welding, which facilitates the connection between the beams and the prefabricated hollow concrete columns.

[0021] The present invention also provides a housing structure system, wherein the outer area including the four corners is defined as a lateral force resisting area, and the middle area is defined as a non-lateral force resisting area, and the system is characterized by:

[0022] The lateral force resisting area includes lateral force resisting columns at least provided at four corners and lateral force resisting beams connected between the lateral force resisting columns at the four corners;

[0023] The non-lateral force resisting area at least includes the beam-column nodes, and prefabricated beams are connected between the beam-column nodes.

[0024] Preferably, the lateral force resisting column and the lateral force resisting beam are rigidly connected or hinged.

[0025] Preferably, an inter-column support is provided between two adjacent lateral force resisting columns at the corners of the house structural system.

[0026] The technical effects of the above technical solution of the utility model come from one or more of the following combinations:

[0027] In this embodiment, all lateral forces are borne by the lateral force resisting support frame (lateral force resisting beams and lateral force resisting columns) of the outer ring, and the outer ring adopts steel tube concrete columns, which have good ductility and excellent seismic performance.

[0028] The central columns are precast hollow concrete columns produced using a centrifugal method. While centrifugally produced hollow concrete columns offer high strength and low production costs, they also exhibit poor ductility. Because they are hinged to the precast beams, they only bear vertical forces and maintain elasticity even in severe earthquakes, ensuring the building's safety despite its high elasticity and low ductility.

[0029] This embodiment innovatively uses prefabricated hollow concrete columns in the frame structure and adopts a hinged connection with the beams, so that the columns do not bear seismic forces, greatly weakening the seismic performance requirements of the column nodes, making it convenient to use hollow columns with a high degree of industrialization in traditional frame structures.

[0030] Precast hollow concrete columns are connected at storey height using standardized steel nodes. The steel nodes are round steel tubes on the outside and filled with high-strength concrete on the inside to achieve the same strength as hollow concrete columns. Precast corbels can be welded directly using a girth welder. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Note that the various aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention.

[0047] Example 1:

[0048] See also Figures 1 to 5 This embodiment describes a beam-column joint comprising a precast hollow concrete column 1, a hoop assembly 2, and a precast corbel. The precast hollow concrete column 1 comprises a steel node segment 10; the hoop assembly 2 comprises at least two hoop segments 21, which are mounted on either side of the steel node segment 10 of the precast hollow concrete column 1, or in a tensioned manner; and the precast corbel is mounted and connected to the hoop 21.

[0049] The steel node segment 10 should be located at the height of the beam-column node. When centrifugally forming a hollow column, a steel pipe segment can be placed in a mold to form the precast hollow concrete column 1. After the precast hollow concrete column 1 is formed, the steel pipe segment is nested outside and does not protrude from the outer periphery of the precast hollow concrete column 1. Therefore, in this embodiment, the steel node segment 10 is preferably implemented as a steel pipe segment that does not protrude from the column.

[0050] In this embodiment, there are two installation modes of the clamp 21:

[0051] 1. Please refer to Figure 1 and Figure 2 The two sections of the clamp 21 are installed on the precast hollow concrete column 1 by tensioning with a tensioning assembly. The tensioning assembly includes an upper tensioning rod group 25 and a lower tensioning rod group 26. The upper tensioning rod group 25 passes through the precast hollow concrete column 1 and its two ends are tensioned at the top position of the two sections of the clamp 21. The lower tensioning rod group 26 passes through the precast hollow concrete column 1 and its two ends are tensioned at the bottom position of the two sections of the clamp 21. Furthermore, the precast corbel is connected to the clamp 21 and is located between the top and bottom positions of the clamp 21. The precast corbel can be directly welded to the clamp 21 using a ring welder.

[0052] 2. Please refer to Figure 4 and Figure 5Specifically, the two ends of the two clamps 21 are formed with ear plates 22, and the two clamps 21 are enclosed in the steel node section 10 and the ear plates 22 are located in the corresponding positions; the prefabricated corbel is hinged to the ear plates 22.

[0053] For further information, see Figure 2 The prefabricated corbel is a prefabricated box 3b, one side of which is shaped to fit the hoop 21, and the other side forms a stepped overlap interface 30 for the prefabricated beam 7 to be overlapped and installed. The end of the prefabricated beam 7 is directly overlapped on the stepped overlap interface 30 to complete the assembled installation.

[0054] Or, as Figure 5 As shown, the prefabricated corbel is an H-shaped steel 3a. When the clamp 21 is installed on the steel pipe section in a closed manner, the web 31 of the H-shaped steel 3a is clamped between the ear plates 22 of the two sections of the clamp 21 and is fastened and installed through bolts 23 to form a hinge.

[0055] like Figure 3 As shown, in order to improve the shear resistance of the steel pipe point, a shear key 24 is formed on the side of the hoop 21 facing the precast hollow concrete column 1; a supporting groove 101 corresponding to the position of the shear key 24 is formed on the side of the precast hollow concrete column 1.

[0056] Please combine Figure 6 and Figure 7 The shear key 24 is clamped in the supporting groove 101 to form a shear effect of the node.

[0057] Furthermore, to create a tensile-resistant effect for the node, a snap-in slot 1011 is formed at the edge of the support slot 101, and a snap-in protrusion 241 is formed at the edge of the shear key 24. This snap-in protrusion 241 snaps into this snap-in slot 1011, and together they form a limit in the tensile direction of the steel node segment 10 and the precast corbel. Furthermore, this snap-in slot 1011 is a beveled slot; correspondingly, the snap-in protrusion 241 also has a corresponding beveled edge 241a to facilitate wedging into the snap-in slot 1011.

[0058] Furthermore, the supporting groove 101 and the beveled groove can be preferably implemented by forming the steel pipe sleeve. Specifically, the supporting groove 101 can be opened on the side of the steel pipe sleeve, and the supporting groove 101 is folded obliquely to form the beveled groove, and then formed by centrifugal molding equipment.

[0059] The beneficial effects of this embodiment are:

[0060] The prefabricated hollow concrete column 1 does not require protruding corbels during factory production, making the production of the centrifugal column convenient and the transportation does not take up a large space due to the protruding nodes.

[0061] The protruding prefabricated corbel is fixed to the prefabricated hollow concrete column 1 by the supporting groove 101 and the shear key 24 for shear resistance, and the bolt 23 for tension resistance. The column extension node can be realized without welding, which facilitates the connection between the beam and the prefabricated hollow concrete column 1.

[0062] Example 2:

[0063] See also Figure 8 and Figure 9 , and combined with Figures 1 to 7 This embodiment describes a building structure system in which the outer area, including the four corners, is defined as a lateral force resisting area A, and the central area is defined as a non-lateral force resisting area B. Furthermore, the lateral force resisting area A includes at least lateral force resisting columns 4 located at the four corners and lateral force resisting beams 5 connecting the lateral force resisting columns 4 at the four corners; the non-lateral force resisting area B includes at least the beam-column nodes described in Example 1, with precast beams 7 connecting the beam-column nodes.

[0064] Furthermore, the lateral force resisting columns 4 and the lateral force resisting beams 5 can be rigidly connected or hinged. Preferably, the connection is rigid, formed directly by welding. Furthermore, an inter-column support 6 is provided between two adjacent lateral force resisting columns 4 at the corners of the building structure system to provide lateral force resistance.

[0065] The beam-column joint located in the non-lateral force resisting area B comprises a precast hollow concrete column 1, a hoop assembly 2, and a precast corbel. The precast hollow concrete column 1 has a steel node section 10; the hoop assembly 2 comprises at least two hoop sections 21, which are mounted together or in tension on either side of the steel node section 10 of the precast hollow concrete column 1; and the precast corbel is mounted and connected to the hoop 21.

[0066] The steel node segment 10 should be located at the height of the beam-column node. When centrifugally forming a hollow column, a steel pipe segment can be placed in a mold to form the precast hollow concrete column 1. After the precast hollow concrete column 1 is formed, the steel pipe segment is nested outside and does not protrude from the outer periphery of the precast hollow concrete column 1. Therefore, in this embodiment, the steel node segment 10 is preferably implemented as a steel pipe segment that does not protrude from the column.

[0067] In this embodiment, there are two installation modes of the clamp 21:

[0068] 1. Please refer to Figure 1 and Figure 2The two sections of the clamp 21 are installed on the precast hollow concrete column 1 by tensioning with a tensioning assembly. The tensioning assembly includes an upper tensioning rod group 25 and a lower tensioning rod group 26. The upper tensioning rod group 25 passes through the precast hollow concrete column 1 and its two ends are tensioned at the top position of the two sections of the clamp 21. The lower tensioning rod group 26 passes through the precast hollow concrete column 1 and its two ends are tensioned at the bottom position of the two sections of the clamp 21. Furthermore, the precast corbel is connected to the clamp 21 and is located between the top and bottom positions of the clamp 21. The precast corbel can be directly welded to the clamp 21 using a ring welder.

[0069] 2. Please refer to Figure 4 and Figure 5 Specifically, the two ends of the two clamps 21 are formed with ear plates 22, and the two clamps 21 are enclosed in the steel node section 10 and the ear plates 22 are located in the corresponding positions; the prefabricated corbel is hinged to the ear plates 22.

[0070] For further information, see Figure 2 The prefabricated corbel is a prefabricated box 3b, one side of which is shaped to fit the hoop 21, and the other side forms a stepped overlap interface 30 for the prefabricated beam 7 to be overlapped and installed. The end of the prefabricated beam 7 is directly overlapped on the stepped overlap interface 30 to complete the assembled installation.

[0071] Or, as Figure 5 As shown, the prefabricated corbel is an H-shaped steel 3a. When the clamp 21 is installed on the steel pipe section in a closed manner, the web 31 of the H-shaped steel 3a is clamped between the ear plates 22 of the two sections of the clamp 21 and is fastened and installed through bolts 23 to form a hinge.

[0072] See also Figure 3 In order to improve the shear resistance of the steel pipe point, a shear key 24 is formed on the side of the hoop 21 facing the precast hollow concrete column 1; a supporting groove 101 corresponding to the position of the shear key 24 is formed on the side of the precast hollow concrete column 1.

[0073] Please combine Figure 6 and Figure 7 The shear key 24 is clamped in the supporting groove 101 to form a shear effect of the node.

[0074] Furthermore, to create a tensile-resistant effect for the node, a snap-in slot 1011 is formed at the edge of the support slot 101, and a snap-in protrusion 241 is formed at the edge of the shear key 24. This snap-in protrusion 241 snaps into this snap-in slot 1011, and together they form a limit in the tensile direction of the steel node segment 10 and the precast corbel. Furthermore, this snap-in slot 1011 is a beveled slot; correspondingly, the snap-in protrusion 241 also has a corresponding beveled edge 241a to facilitate wedging into the snap-in slot 1011.

[0075] Furthermore, the supporting groove 101 and the beveled groove can be preferably implemented by forming the steel pipe sleeve. Specifically, the supporting groove 101 can be opened on the side of the steel pipe sleeve, and the supporting groove 101 is folded obliquely to form the beveled groove, and then formed by centrifugal molding equipment.

[0076] Beneficial effects of this embodiment:

[0077] In this embodiment, all lateral forces are borne by the lateral force resisting support frame (lateral force resisting beams 5 and lateral force resisting columns 4) of the outer ring, and the outer ring adopts steel tube concrete columns with good ductility and excellent seismic performance.

[0078] The central columns are precast hollow concrete columns 1 produced using a centrifugal method. While centrifugally produced hollow concrete columns offer high strength and low production costs, they also exhibit poor ductility. Because they are hinged to the precast beams 7, they only bear vertical forces and maintain elasticity even in severe earthquakes. This characteristic of high elasticity and low ductility ensures the building's safety.

[0079] This embodiment innovatively uses prefabricated hollow concrete columns 1 in the frame structure and adopts a hinged connection with the beam, so that the columns do not bear seismic forces, greatly weakening the seismic performance requirements of the column nodes, making it convenient to use hollow columns with a high degree of industrialization in traditional frame structures.

[0080] The precast hollow concrete column 1 is connected at the floor level with a standardized steel node. The steel node is a round steel tube on the outside and filled with high-strength concrete on the inside to achieve the same strength as the hollow concrete column. The precast bracket can be directly welded with a circular welder.

[0081] Furthermore, the present invention has been described in detail above with reference to the accompanying embodiments. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, which shall be protected by the scope defined in the appended claims.
