Due to the different lengths and shapes of beams, they need to be connected at some key locations, namely the beam nodes. The location and connection method of beam nodes have a very important impact on the load-bearing capacity and stability of the building structure.

Utility Model Content
[0005] In order to improve the problem of floor height occupation by wooden joists, the present application provides a double wooden column sandwiching a wooden beam node.
[0006] The present application provides a double-wood column sandwiched with a wooden beam node using the following technical solution:
[0007] A double-wood column-and-wood beam node comprises a main crossbeam, main columns are arranged on both sides of the end of the main crossbeam, longitudinal beams are arranged on the main columns, a plurality of joists are arranged along the length direction of the main crossbeam, joist grooves are opened from the middle position of the top of the main crossbeam to both ends thereof, the joist grooves on the main crossbeam are used to place joists, the tops of the joists are flush with the top of the main crossbeam, partitions are arranged between two adjacent joists in the joist grooves, the main crossbeam separates the joists at its ends, and connecting components are arranged between the joists at the ends of the main crossbeam and the main crossbeam.
[0008] By adopting the above technical solution, by opening a joist groove from the middle of the top of the main beam to both ends, the top of the joist is made flush with the top of the main beam, thereby reducing the total beam height and reducing the occupation of the house floor height, which is beneficial to reducing economic costs. Since the connection between the main beam and the main column is the area with a large negative bending moment of the entire main beam, and the cross-section of the end of the main beam is larger than the cross-section in the middle, the end of the main beam can bear a large negative bending moment, and the connecting assembly is convenient for workers to keep the top of the joist at the end of the main beam flush with the top of the main beam.
[0009] Optionally, the partition comprises a partition plate arranged on the joist groove, and connecting plates are arranged between the main crossbeam and the partition plate, between the main crossbeam and the joist, and between the partition plate and the joist.
[0010] By adopting the above technical solution, workers use partitions to evenly arrange multiple joists on the main beam in sequence, and then fix them through connecting plates. Since the size of each partition is the same, it is helpful to reduce the installation difficulty of workers.
[0011] Optionally, a positioning hole is provided on the connecting piece, and the positioning hole is used to install a screw. The connecting piece is provided with an anti-loosening thorn, and the anti-loosening thorn is used to pierce the main crossbeam.
[0012] By adopting the above technical solution, workers fix the connecting piece on the main beam by screwing the screws. As the workers screw the screws, the anti-loosening thorns are gradually screwed into the main beam, which helps to reduce the possibility of movement of the joists.
[0013] Optionally, the connecting assembly includes a bearing plate arranged on the main beam, the joists at the ends of the main beam are arranged on the bearing plate, a positioning block is arranged on the bearing plate, the joists at the ends of the main beam are provided with supporting grooves for supporting the positioning block, a fastening screw is detachably arranged on the bearing plate, the fastening screw passes through both sides of the main beam, a fastening nut is threadedly connected to the fastening screw, and the fastening nut is used to press the bearing plate onto the main beam.
[0014] By adopting the above technical solution, workers first install the fastening screws on the main beam, and then fix the bearing plate on the main beam through the fastening nuts, so that the position heights of the bearing plates on both sides of the main beam are the same, so that the joists on both sides of the main beam are on the same height straight line, and the positioning blocks facilitate workers to install the joists.
[0015] Optionally, the positioning block is slidably arranged on the supporting plate, a bidirectional screw is rotatably arranged on the supporting plate, both ends of the bidirectional screw are threadedly connected with sliding blocks, the sliding block is slidably matched with the supporting plate, and a support rod is connected between the two sliding blocks and the positioning block.
[0016] By adopting the above technical solution, when the top of the joist at the end of the main beam is not flush with the top of the main beam, the worker turns the bidirectional screw in the forward direction, and the bidirectional screw rotates to make the two sliding blocks approach each other. The sliding block supports the positioning block through the support rod, and the positioning block lifts the joist, so that the top of the joist is flush with the top of the main beam, which helps to reduce the difficulty of adjustment for the workers.

[0019] Optionally, the tensioning member comprises a tensioning cylinder, both ends of the tensioning cylinder are threadedly connected with tensioning screws, and one end of the tensioning screw facing away from the tensioning cylinder is detachably arranged on the joist.
[0020] By adopting the above technical solution, the worker twists the tensioning cylinder forward. Since the end of the tensioning screw is fixed on the joist, the rotation of the tensioning cylinder causes the two tensioning screws on it to move away from each other, and the tensioning screw pushes the joist, thereby adjusting the joist spacing at the end of the main beam.
[0021] Optionally, a secondary crossbeam is arranged on the longitudinal beam, and the secondary crossbeam is parallel to the main crossbeam.
[0022] By adopting the above technical solution, workers erect the secondary crossbeam on the longitudinal beam, thereby enabling the secondary crossbeam to be cantilevered on the longitudinal beam.

[0024] 1. By opening a joist groove from the middle of the top of the main beam to both ends, the top of the joist is flush with the top of the main beam, thereby reducing the total beam height and reducing the occupation of the house floor height, which is conducive to reducing economic costs. Since the connection between the main beam and the main column is the area with a large negative bending moment of the entire main beam, and the cross-section of the end of the main beam is larger than the cross-section in the middle, the end of the main beam can bear a large negative bending moment. The connection assembly facilitates workers to keep the top of the joist at the end of the main beam flush with the top of the main beam;

The sliding block supports the positioning block through the support rod, and the positioning block lifts the joist to make the top of the joist flush with the top of the main beam, which helps to reduce the difficulty of adjustment for workers.
