[0036] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1:

[0038] like Figure 2 to Figure 4As shown, this embodiment proposes a beam-column connecting member, whose structure includes a center member 5 and a column end member 11. In this embodiment, the first column mounting plate 21 is fixedly disposed on the side of the center member 5 away from the column end member 11, and is used to connect and install the first column member 1. The second column mounting plate 111 is disposed on the side of the column end member 11 away from the center member 5, and is used to connect and install the second column member 2. The first mounting tube 51 is fixedly disposed on the center member 5, and the second mounting tube 112 is fixedly disposed at the lower end of the column end member 11. The first mounting tube 51 is slidably connected to the second mounting tube 112, and is used to connect the center member 5 and the column end member 11. The cross-section of the first mounting tube 51 and the second mounting tube 112 is a U-shaped structure. The first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44 are respectively provided on the side walls of the first mounting tube 51. The first mounting hole 211 is provided on the first column mounting plate 21 and the second column mounting plate 111. The second mounting hole 411 is provided on the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44. In this embodiment, since the first column component 1 is above the second column component 2, under the weight of the first column component 1 itself, the second mounting tube 112 on the first column component 1 itself is difficult to separate from the first mounting tube 51. Therefore, the installation between the first column component 1 and the second column component 2 can be achieved even without the use of bolts. Not only does it save the installation process, but it can also prevent the installation hole from being offset between the center piece 5 and the column component due to transportation, which makes it difficult to install.

[0039] During on-site installation, the prefabricated threaded steel bar 33 extending through the installation end of the first column member 1, the second column member 2, the first column mounting plate 21 and the second column mounting plate 111 is first passed through the first mounting hole 211 and connected with the prefabricated locking bolt 34 of matching size. Then, the column end member 11 and the center member 5 of matching size are connected by inserting the second mounting tube 112 into the first mounting tube 51. Finally, the beam member 3, the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44 are inserted through the mounting groove 31 on the beam member 3, the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44, and are fixedly connected to the beam member 3 through the second mounting hole 411 by the steel bar 33. In this way, the construction of the current floor is completed, and the operation of the subsequent floors is the same, and the cycle is repeated to realize the construction upward layer by layer.

[0040] Embodiment 2:

[0041] In order to reduce the collision damage to the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44 when transporting the center piece 5, and to reduce the transportation space when transporting the center piece 5. Figures 5 to 8As shown, on the basis of Example 1, the first mounting tube 51 in this embodiment is provided with a first plug-in slot 52, a second plug-in slot 53, a third plug-in slot 54 and a fourth plug-in slot 55 on the side walls thereof, one end of the first plug-in slot 52 is connected to the top of the first mounting tube 51, and the spacing length between the bottom of the first plug-in slot 52 and the first column mounting plate 21 is equal to the depth of the first plug-in slot 52, the fifth plug-in slot 412 is arranged on the first column mounting plate 21, the fifth plug-in slot 412 is connected to the bottom of the first column mounting plate 21, and the spacing length between the fifth plug-in slot 412 and the top of the first column mounting plate 21 is equal to the depth of the fifth plug-in slot 412, the first plug-in slot 52 is slidably connected to the first plug-in slot 52, and the structures of the first column mounting plate 21, the second column mounting plate 111, the third column mounting plate and the fourth column mounting plate are the same. In this embodiment, the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44 are assembled by inserting the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44 into the first plug-in slot 52, the second plug-in slot 53, the third plug-in slot 54 and the fourth plug-in slot 55, so that the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44 and the center piece 5 are transported separately, which not only saves transportation space but also effectively prevents the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44 from collision damage during transportation.

[0042] In this embodiment, the first positioning plate 71 is fixedly arranged on the side of the first beam mounting plate 41 close to the first mounting tube 51, the second positioning plate 72 is fixedly arranged on the side of the second beam mounting plate 42 close to the first mounting tube 51, the third positioning plate 73 is fixedly arranged on the side of the third beam mounting plate 43 close to the first mounting tube 51, and the fourth positioning plate 74 is fixedly arranged on the side of the fourth beam mounting plate 44 close to the first mounting tube 51. The two ends of the first positioning plate 71 are respectively abutted against the inner wall of the first mounting tube 51 and the second positioning plate 72, the two ends of the second positioning plate 72 are respectively abutted against the inner wall of the first mounting tube 51 and the third positioning plate 73, the two ends of the third positioning plate 73 are respectively abutted against the inner wall of the first mounting tube 51 and the fourth positioning plate 74, and the two ends of the fourth positioning plate 74 are respectively abutted against the inner wall of the first mounting tube 51 and the first positioning plate 71. The first positioning plate 71, the second positioning plate 72, the third positioning plate 73 and the fourth positioning plate 74 form a sliding groove 711, and the second mounting tube 112 is slidingly connected to the sliding groove 711. Such a design, under the action of the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44, the first positioning plate 71, the second positioning plate 72, the third positioning plate 73, the fourth positioning plate 74 and the inner wall of the first mounting tube 51, not only forms a sliding groove 711 with a stable structure, but also can be disassembled and installed.

[0043] The positioning platform 113 in this embodiment is arranged on the side of the second column mounting plate 111 close to the second mounting tube 112, and the positioning platform 113 is slidably connected to the first mounting tube 51, and the positioning platform 113 is respectively abutted against the first positioning plate 71, the second positioning plate 72, the third positioning plate 73 and the fourth positioning plate 74. In this embodiment, the first beam mounting plate 41, the second beam mounting plate, the third beam mounting plate 43 and the fourth beam mounting plate 44 are all provided with notches near the top of the inner side of the first mounting tube 51, and the positioning platform 113 is arranged in the notch and slidably connected to the notch. Such a design can not only make the installation position of the first mounting tube 51 more accurate, but also under the action of the positioning platform 113, the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44 are all squeezed onto the first column mounting plate 21, and the installation is more firm and reliable.

[0044] The cross section of the sliding groove 711 in this embodiment is a circular structure, the cross section area of ​​the notch of the sliding groove 711 is larger than the cross section area of ​​the bottom of the sliding groove 711, and the cross section area of ​​the second mounting tube 112 close to the second column mounting plate 111 is larger than the cross section area of ​​the second mounting tube 112 away from the second column mounting plate 111. In this design, since the cross section area of ​​the notch of the sliding groove 711 is larger than the cross section area of ​​the second mounting tube 112 close to the second mounting plate, the second mounting tube 112 is easier to enter the notch of the sliding groove 711, which facilitates the assembly of the center piece 5 and the column end piece 11.

[0045] The stiffening plate 6 in this embodiment is fixedly arranged on both sides of the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44. The stiffening plate 6 is a right-angled triangle structure. Such a design not only minimizes the area of ​​the stiffening plate 6, but also strengthens the bending resistance of the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44. The bottom of the stiffening plate 6 abuts against the first column mounting plate 21. Such a design has a stronger bending resistance of the center piece 5 and a more stable structure.

[0046] In this embodiment, the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44 are welded to the stiffening plate 6, the first column mounting plate 21 is welded to the first mounting tube 51, and the second mounting tube 112 is welded to the second column mounting plate 111. This design allows these center pieces 5 and column end pieces 11 to be transported separately and assembled and welded at the work site, reducing transportation and storage space.

[0047] The second invention purpose of the present invention is to provide an assembled wooden beam column, including a beam member 3, a first column member 1 and a second column member 2, and also a beam-column connector, wherein a mounting groove 31 is arranged at the end of the beam member 3, and the mounting groove 31 is slidably connected with the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 or the fourth beam mounting plate 44, a plurality of third mounting holes 32 are arranged on the side wall of the beam member 3, and a steel bar 33 is slidably arranged in each third mounting hole 32, and the steel bar 33 is slidably connected with the second mounting hole 411, and a locking bolt 34 is threadedly connected with both ends of the steel bar 33, and a connecting surface 12 is arranged at the end of the first column member 1 and the second column member 2, and the connecting surface 12 is threadedly connected with the first column mounting plate 21 or the second column mounting plate 111 through the first mounting hole 211. After the beam member 3 of this embodiment is installed, the direction of the mounting groove 31 is perpendicular to the ground, and such a design is to facilitate the hoisting equipment to be placed from top to bottom into the first beam mounting plate 41 or the second beam mounting plate 42 or the third beam mounting plate 43 or the fourth beam mounting plate 44. This design has the following advantages: 1. This embodiment uses a plurality of third mounting holes 32 and second mounting holes 411 to connect the beam member 3 and the center piece 5. After the connection is completed, the structure is more stable and is not easy to be displaced or loosened when receiving the bearing load; 2. The sliding connection is used in conjunction with the locking bolts 34, making the transfer and disassembly more convenient and reliable. The beam member 3 and the wooden frame used in this embodiment are both made of wood, while the center piece 5 and the column end piece 11 are made of steel. The beams and columns of the wooden structure give the building a better visual effect, and the steel structure is more solid and reliable. The first column member 1 used in this embodiment is threadedly connected and fixed to the second column mounting plate 111, and the second column member 2 is threadedly fixed to the first column mounting plate 21.

[0048] The column components and beam components 3 as well as the column end components 11 and center components 5 made of metal are all prefabricated components. Their specific dimensions and requirements for opening holes and slotting are determined according to the design. After cutting, processing, opening holes and slotting in the factory, the finished products are directly transported to the site, saving on-site construction time.

[0049] The third invention object of the present invention is to provide a wood structure beam-column node, which is assembled by a prefabricated wood beam-column to form a wood structure node. This embodiment can be split into multiple beam components 3 and column components for assembly, and is suitable for large-span wood building structures and high-rise wood building structures.

[0050] The fourth invention object of the present invention is to provide a construction method for assembling wooden beams and columns, comprising the following steps:

[0051] S1: First, insert the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44 into the first insertion slot 52, the second insertion slot 53, the third insertion slot 54 and the fourth insertion slot 55 through their respective fifth insertion slots 412, and then install the center piece 5 and the column end piece 11 to the first column component 1 and the second column component 2 by bolts. This design is to allow the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43 and the center piece 5 to be transported separately, and the sheet-type structure can be stacked during transportation, which not only saves transportation space, but also is not easy to be damaged by collision during transportation.

[0052] S2: Use the hoisting equipment to hoist the first column component 1 to be assembled to the specified position, then adjust the second installation tube 112 on the column end member 11 to align with the sliding groove 711 on the center member 5, and then insert the second installation tube 112 into the sliding groove 711. The design of the sliding groove 711 on the second installation tube 112 and the center member 5 in this embodiment makes the docking during the insertion process smoother and more secure. This sliding connection not only improves the stability of the structure, but also reduces the connection problems caused by improper construction.

[0053] S3: Use the hoisting equipment to hoist the beam member 3 to be assembled to the designated position, adjust the mounting groove 31 on the beam member 3 to align with the first beam mounting plate 41 on the center member 5, and align the third mounting hole 32 with the second mounting hole 411, then pass the steel bar 33 through the second mounting hole 411 and the third mounting hole 32 at the same time, and connect and fix the steel bar 33 to the beam member 3 through the locking bolt 34. The locking connection of the steel bar 33 increases the integrity and stability between the beam member 3 and the column, thereby improving the seismic resistance of the structure under external forces such as earthquakes.

[0054] S4: Repeat step S3 to install the beam member 3 on the second beam mounting plate 42, the third beam mounting plate 43 and the fourth beam mounting plate 44 respectively.

[0055] In this embodiment, the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43, and the fourth beam mounting plate 44 can be first mounted on the end surface of the beam component 3, the second column component 2 can be mounted on the lower end of the center piece 5, the first column component 1 can be mounted on the column end piece 11, and then the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43, and the fourth beam mounting plate 44 on the beam can be used to mount it on the center piece 5, and finally the first column component 1 and the center piece 5 can be assembled by the crane. This design reduces the process of screwing when the beam component 3 is installed with the first beam mounting plate 41, the second beam mounting plate 42, the third beam mounting plate 43, and the fourth beam mounting plate 44 when the crane is used for hoisting, and it can be assembled when working on the ground, which reduces the use time of the crane, not only saves production costs, but also improves its assembly accuracy.
