A wooden beam string structure

Abstract

A wooden tensioned beam structure belongs to the field of building technology. It includes a main beam with a first accommodating cavity provided at the end; a support embedded in the first accommodating cavity and fixedly connected to the main beam; and a cable connecting the supports at both ends of the main beam. The present invention sets a first accommodating cavity at both ends of the main beam, embeds the support connected to the cable in the first accommodating cavity, and fixes it to the main beam, so that the cable provides prestress to the main beam. Since the support is embedded in the main beam, the tension of the cable is borne by the main beam as a whole at the first accommodating cavity, rather than the force point being biased to one side. Therefore, the force of the present invention is more balanced. Compared with the prior art in which the connecting part connecting the cable is set on one side of the main beam, the present invention avoids the problem of the main beam bulging and bending to the other side after being stressed, and generating a torsional torque on the connecting part, which causes it to damage the main beam and detach. Therefore, the force of the present invention is more balanced, and thus less likely to be damaged, and has a longer service life.

Description

Technical Field

[0001] The present invention relates to the technical field of buildings, and in particular to a wooden beam string structure. Background Art

[0002] The beam string structure is a hybrid structural system consisting of a rigid upper chord, flexible cables, and intermediate struts. Its structural composition is a new type of self-balancing system and also a large-span prestressed spatial structural system.

[0003] Currently, beam-string structures used in wooden buildings use screws to attach plate-shaped connectors to the outside ends of a wooden upper beam. The connectors at both ends of the upper beam are connected to cables, which provide prestress to the upper beam to support the roof. However, because the connectors are mounted on the outside of the upper beam, tension from the cables causes the screw ends in contact with the connector to generate a torsional moment in the direction of the tension. This in turn causes the screw ends, located inside the upper beam, to generate a torsional moment in the opposite direction. This means the torsional moment shifts from perpendicular to the cable direction to parallel to the cable direction. Consequently, the upper beam is constantly subjected to the concentrated force of the screws. Since the upper beam is made of wood and has relatively low rigidity, the screws are easily damaged at the locations where they are mounted, causing them to pull out. In this case, the cables are unable to provide prestress, causing the upper beam to be damaged by roof pressure. Furthermore, because the connectors are located on one side of the upper beam, the upper beam, subjected to cable tension, deforms and bends toward the other side, further damaging the upper beam. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of the prior art wooden beam string structure that the upper beam is easily damaged due to the connector connecting the cables being located outside the upper beam, thereby providing a wooden beam string structure.

[0021] The first connecting member and the slot are plug-fitted and connected, and are connected through a reinforcing bar arranged along the radial direction of the secondary beam.

[0022] Optionally, the first connecting member is a T-shaped structure consisting of a horizontal plate and a vertical plate;

[0028] The second connecting structure is used to connect the main beam, the secondary beam and the roof support, which includes: a T-shaped structure composed of a horizontal plate and a vertical plate, and connecting plugs arranged on both sides of the vertical plate; the T-shaped structure is used to connect the main beam and the secondary beam, and the connecting plugs are plugged into and fixedly connected with the slots on the roof support.

[0029] Optionally, the wooden beam string structure further comprises:

[0030] a support column, supporting the support; and / or,

[0031] A frame beam, wherein the middle portion of the frame beam is connected to the support column, and both ends of the frame beam are embedded in the secondary beam.

[0032] The technical solution of the present invention has the following advantages:

[0033] 1. The wooden beam-string structure provided by the present invention includes a main beam with a first accommodating cavity provided at the end thereof; a support embedded in the first accommodating cavity and fixedly connected to the main beam; and a cable connecting the supports at both ends of the main beam.

[0034] The present invention sets a first accommodating cavity at both ends of the main beam, embeds the support for connecting the cable in the first accommodating cavity, and is fixedly connected to the main beam, so that the cable provides prestress to the main beam. Since the support is embedded in the first accommodating cavity of the main beam, the main beam and the support form an integral structure. Therefore, the tension of the cable is borne by the main beam as a whole at the first accommodating cavity, rather than the force point being biased to one side. Therefore, the present invention is more balanced in force. Compared with the prior art in which the connecting member for connecting the cable is set on one side of the main beam, the present invention avoids the problem of the main beam bulging and bending to the other side after being stressed, and the problem of the connecting member generating a torsional torque, which causes it to damage the main beam and detach. Therefore, the present invention is more balanced in force, less likely to be damaged, and has a longer service life.

[0035] 2. The wooden beam-string structure provided by the present invention has the main beam made of wood.

[0036] The structure of the present invention can be used on wooden buildings, that is, the main beam is made of wood, so that large-span wooden buildings can avoid the need to set up more support columns by using the structure of the present invention, thereby increasing the usable space in the building and improving the neatness of the wooden building. At the same time, since the support is embedded in the main beam, compared with the prior art in which the connecting parts are set on the outside of the main beam, the present invention reduces the exposed area of ​​the support, that is, reduces the exposed area of ​​the steel structure in the wooden building, thereby improving the aesthetics of the wooden building.

[0037] 3. In the wooden beam-string structure provided by the present invention, the support is a plate-like structure; the support and the main beam are connected through rebars arranged in a vertical direction along the support.

[0038] The present invention sets up anchor bolts arranged along the vertical direction of the support to penetrate and connect the support and the main beam, so that the tension exerted on the support is transmitted to the main beam through the anchor bolts. Since the anchor bolts penetrate the main beam, the tension exerted on the support will be evenly transmitted to the main beam as a whole, rather than to one side. This avoids the problem in the prior art that the connecting part connecting the cable is set on one side of the main beam, which causes the main beam to bulge and bend to the other side after being subjected to force, and the tension generates a torsional torque on the connecting part, causing it to damage the main beam and detach.

[0039] 4. The wooden tensioned beam structure provided by the present invention also includes a strut, one end of which is connected to the main beam and the other end is connected to the cable to provide prestress to the main beam. The end of the strut is embedded in the main beam and is connected to the main beam through a rebar.

[0040] The present invention arranges a strut on the cable to provide prestress to the main beam. The end of the strut is embedded in the main beam, so that the strut is connected to the main beam and plays a positioning role, avoiding the deviation of the strut and the main beam after being stressed, thereby causing insufficient prestress. The rebar embedding part connects the end of the strut with the main beam through and through, further stabilizing the connection between the strut and the main beam, and at the same time evenly transferring the prestress provided by the strut to the main beam, avoiding the deviation and bending of the main beam due to uneven stress.

[0041] 5. The wooden beam string structure provided by the present invention further includes a secondary beam, which is arranged in the radial direction of the main beam and connected to the main beam, and a plurality of the secondary beams are arranged along the length direction of the main beam.

[0042] The present invention arranges secondary beams along the radial direction of the main beam, and multiple secondary beams are arranged along the length direction of the main beam, so that the secondary beams and the main beam support the roof at the same time, thereby increasing the stress points on the roof that are supported by the force, making the force more balanced, and preventing the roof from being deformed due to a small number of stress points.

[0043] 6. The wooden tensioned beam structure provided by the present invention also includes a first connecting structure for connecting the main beam and the secondary beam, which includes: a first connecting member arranged on one of the side of the main beam and the end of the secondary beam, and a slot arranged on one of the side of the main beam and the end of the secondary beam; the first connecting member and the slot are plug-in connected, and are connected through a rebar member arranged along the radial direction of the secondary beam.

[0044] The present invention provides a first connecting piece to connect the main beam and the secondary beam. The first connecting piece and the slot are plugged in and connected to play a limiting role to prevent the secondary beam and the main beam from offsetting or moving. The first connecting piece and the slot are connected through the rebar piece arranged along the radial direction of the secondary beam, so that the pressure on the secondary beam can be evenly transferred to the main beam. Compared with the first connecting piece being connected to one side of the secondary beam, it can avoid the secondary beam being bent to the other side due to force, and the problem of the first connecting piece being detached from the secondary beam.

[0045] 7. In the wooden beam-string structure provided by the present invention, the first connecting member is a T-shaped structure consisting of a horizontal plate and a vertical plate; the horizontal plate is fitted and connected to one of the main beam and the secondary beam, and the vertical plate is fitted and connected to the slot on the other of the main beam and the secondary beam.

[0046] The first connecting member of the present invention is configured as a T-shaped structure, wherein the horizontal plate is fitted and connected to one of the main beam and the secondary beam, and the vertical plate is plugged and connected to the slot on the other of the main beam and the secondary beam, so that the horizontal plate is located between the main beam and the secondary beam, and the vertical plate is located inside the slot, so that the first connecting member will not be exposed. When the main beam and the secondary beam of the present invention are made of wood, the steel structure can be avoided from being exposed, thereby enhancing the aesthetics.

[0047] 8. In the wooden beam-string structure provided by the present invention, the first connecting member adjacent to the strut further has a protrusion extending toward the strut, and the protrusion is connected to the adjacent strut via a corner brace.

[0048] The first connecting member adjacent to the support rod of the present invention is provided with a protrusion, which is connected to the support rod through a corner brace, so that the secondary beam connected to the first connecting member is connected to the support rod through the corner brace. The tension applied to the support rod by the corner brace ensures that the support rod and the cable remain stable, avoiding the cable from becoming unstable and flipping.

[0049] 9. In the wooden beam string structure provided by the present invention, each of the support rods is symmetrically provided with a corner brace on both sides thereof, and the corner brace is a tension rod type corner brace.

[0050] The support rod of the present invention is symmetrically provided with a corner brace on each side, so that the lateral force generated by the corner brace on the support rod can be offset, thereby preventing the support rod from being tilted and unstable due to the force of the corner brace on only one side, thereby causing the cable to become unstable and flip; the cross-section of the pull rod corner brace is smaller, which can further improve the aesthetics of the building.

[0051] 10. The wooden beam-string structure provided by the present invention further includes a roof support member, which is arranged between the matingly connected main beam and the secondary beam to form a M-shaped support structure; a second connecting structure, which is used to connect the main beam, the secondary beam and the roof support member, and includes: a T-shaped structure composed of a horizontal plate and a vertical plate, and connecting plugs arranged on both sides of the vertical plate; the T-shaped structure is used to connect the main beam and the secondary beam, and the connecting plugs are matingly plugged into the slots on the roof support member to be fixedly connected.

[0052] The present invention provides a second connecting structure to connect the main beam and the secondary beam, and is connected to the roof support member through the connecting plug plate of the second connecting structure. The roof is further supported by the roof support member. The roof support member is arranged between the matingly connected main beam and the secondary beam to form a M-shaped support structure, which can make the lateral forces of the roof support member offset each other, thereby preventing the main beam and the secondary beam from being bent and damaged due to the lateral force.

[0053] 11. The wooden beam-string structure provided by the present invention further includes a support column to support the support; a frame beam, the middle portion of the frame beam is connected to the support column, and both ends of the frame beam are embedded in the secondary beam.

[0054] The support of the present invention is arranged on the support column, so that the tension of the cable is directly transmitted to the support column through the support. Compared with the prior art in which the main beam is directly connected to the support column, the connecting piece of the cable is located on one side of the support column, so that the tension of the cable needs to act on the main beam first and then be transmitted to the support column by the main beam. Since the support for connecting the cable is arranged on the support column, the present invention avoids the tension of the cable acting on the two ends of the main beam in opposite directions, causing the ends of the main beam to be subjected to excessive force and damaged; the frame beam further supports the secondary beam, and the pressure on the frame beam acts directly on the support column, thereby reducing the pressure on the main beam and improving the service life of the main beam. The two ends of the frame beam are embedded in the secondary beam, which plays a positioning role on the one hand to avoid the movement of the frame beam and the secondary beam, and on the other hand reduces the leakage of the steel structure and improves the aesthetics.
