[0002] The steel-wood combined wood beam refers to adding steel in the structure of the wood beam to enhance the strength and stability of the wood beam. This structural design is often used in the beam-column structure of large-span buildings to meet the load requirements of the building. The design principle of the steel-wood combined wood beam is to combine the high strength of steel with the light weight and easy processing of wood to form a more solid and stable structure. In practical applications, steel is usually used to strengthen the bottom or top of the wood beam to enhance the bending and shearing resistance of the wood beam. The advantages of the steel-wood combined wood beam include a solid structure, light weight, easy processing, low cost, etc. At the same time, this structural design can also improve the seismic resistance and durability of the building, making the building safer and more reliable.

[0003] However, the existing steel-wood combined wood beam is usually connected by steel structure connectors at both ends during installation. When solid wood beams are installed, the two ends of the wood beam will bear a large pressure, which may cause damage or rupture at the installation site of the two ends of the wood beam. UTILITY MODEL CONTENT

[0004] The utility model aims to provide a steel-wood combined wood beam to solve the problem of the existing steel-wood combined wood beam being usually connected by steel structure connectors at both ends during installation, which may cause damage or rupture at the installation site of the two ends of the wood beam when solid wood beams are installed.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a steel-wood combined wood beam, comprising a stand column and a plurality of fixed screw holes arranged around the stand column.

[0006] The installation plate is arranged around the stand column, the vertical steel plate is arranged on the installation plate, a plurality of through holes are arranged on the vertical steel plate, the total crossbeam is arranged on the vertical steel plate, and a plurality of transverse fixed screws are arranged on the side surface of the total crossbeam.

[0008] Preferably, the support cross beams are integrally connected with the general cross beam, and the support cross beams are arranged at four corner positions of the cross section of the general cross beam respectively.

[0009] Preferably, the support steel piece is integrally connected with the fixing foot, the fixing foot is fixedly connected with the support cross beam through a screw, the support steel piece is in the shape of a trapezoid, and the support steel piece is made of high-strength steel.

[0010] Preferably, the plug block pin is integrally connected with the longitudinal plug block, and the longitudinal plug block can be inserted with the clamping groove on the support cross beam through the plug block pin.

[0011] Preferably, the convex block is integrally connected with the transverse plug block, the transverse plug block can be inserted with the recess on the longitudinal plug block through the convex blocks at two ends, the top, bottom and side of the longitudinal plug block are respectively provided with a plurality of through holes, and the top surface of the transverse plug block is provided with a plurality of through holes.

[0012] Preferably, the top of the transverse plug block and the support cross beam is provided with a fixing sheet, the transverse plug block is fixedly connected with the support cross beam through the fixing sheet, and the longitudinal plug block is fixedly connected with the side of the support cross beam through the fixing sheet.

[0013] Preferably, the bottom of the vertical plug-in steel plate is provided with a bottom plate, the bottom plate is welded with the vertical plug-in steel plate and the mounting plate, the bottom of the general cross beam is provided with a bottom plate groove, a vertical insertion groove is arranged in the middle of the bottom plate groove, and the bottom of the general cross beam is provided with a plurality of bottom through holes.

[0014] Compared with the prior art, the steel-wood combined wood beam has the following beneficial effects:

[0015] 1. Compared to traditional steel-wood composite beams, this wooden beam system, with its main crossbeam and supporting crossbeams, features four supporting crossbeams in the middle section. These supporting crossbeams are significantly lighter than solid wood beams, and the use of solid wood at both ends ensures a more stable installation. Through the use of slots, longitudinal inserts, insert feet, and fixing plates, a pair of longitudinal inserts is placed at intervals between the four supporting crossbeams. The longitudinal inserts engage with the slots on the two supporting crossbeams on the same side via their insert feet. The fixing plates on the sides then secure the longitudinal inserts to the supporting crossbeams. The crossbeam's snap-fit ​​mechanism provides longitudinal support and fixation. Through the arrangement of transverse inserts, protrusions, grooves, and fixing plates, the transverse inserts can be inserted into the grooves on both sides via protrusions on both sides. Then, the fixing plates at the top securely connect the transverse inserts to the top of the longitudinal inserts, thus fixing and supporting the crossbeam laterally. Compared to traditional steel-wood composite beams, this structure reduces the overall weight of the wooden beam by using crossbeams, ensuring that the connection between the vertical steel plates at both ends and the main crossbeam is not subjected to excessive pressure, thereby preventing the ends of the crossbeam from breaking or being damaged due to excessive pressure.

[0016] 2. By setting fixed feet and supporting steel components, multiple supporting steel components are set on the side of the crossbeam. These supporting steel components are connected end to end and fixedly installed. On the one hand, the supporting steel components can fix the side of the crossbeam. On the other hand, because the supporting steel components adopt a trapezoidal structure, the installation on the side of the crossbeam can effectively improve the crossbeam's seismic resistance and overall strength. By setting a base plate, base plate groove, and bottom through hole, compared with the traditional method of only using horizontal fixing, this structure adds a base plate. When connecting the main crossbeam to the vertical insert steel plate, it is not only fixed by horizontal fixing screws, but also by the snap-fit ​​of the base plate with the base plate groove and the fixing of the base plate to the main crossbeam through the bottom through hole, thus longitudinally fixing the bottom of the main crossbeam. The base plate can support the bottom of the main crossbeam, effectively reducing the pressure on the horizontal fixing screws and preventing the horizontal fixing screws from breaking due to excessive pressure, while ensuring the integrity of both ends of the main crossbeam.
