[0002] A wooden house refers to a house made of wood. Wooden structures are generally divided into light wooden structures and heavy wooden structures in terms of structural form. The foundation is made of ground screws, and the main structural components are all made of solid wood products. Wooden houses are warm in winter and cool in summer, and are beneficial to health preservation. The advantages of wooden structures are different from traditional steel-concrete structures. They are known for their energy saving, ecology, and environmental protection. Its benefits also include resistance, thermal insulation, and durability. It also has a nice name called "breathing house". Wooden houses contain phytoncides and negative ions, which are known as the vitamins of the air. Therefore, living in wooden houses regularly will be very helpful to people's health.

[0003] The existing wooden house has a cumbersome assembly process, and the stability of the corner columns and foundation columns of the wooden house is poor after installation, and it is easy to fall off and shake after installation, which is not conducive to the overall safety and stability of the house. For this reason, we propose a connection structure between the corner columns and the foundation columns. Summary of the invention

[0004] The object of the present invention is to provide a connection structure between a positive corner column and a base column to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a connection structure between a positive corner column and a foundation column, comprising a foundation column, an aluminum-wood composite ring beam and an aluminum-wood composite corner column, the aluminum-wood composite ring beam is provided with two groups, the two groups of aluminum-wood composite ring beams are connected to the foundation column by bolts, the foundation column is vertically connected to the aluminum-wood composite ring beam, the foundation column and the aluminum-wood composite ring beam are connected by aluminum tenons and aluminum mortises, the aluminum-wood composite corner column is installed on the top of the foundation column, and a steel pad is provided between the foundation column and the aluminum-wood composite corner column, the steel pad is provided with high-strength bolt mounting holes, the high-strength bolt mounting holes are provided with multiple groups, and the foundation column has multiple groups of mounting holes.

[0006] Furthermore, the aluminum-wood composite ring beam includes ring beam wood, ring beam aluminum and ring beam decorative materials. The ring beam wood is installed on the ring beam aluminum by wood screws, the ring beam decorative materials are snap-fitted and installed on the outer wall of the ring beam aluminum, the ring beam aluminum is installed on the foundation column by bolts, the ring beam wood is installed on the ring beam aluminum by wood screws, which facilitates the connection between the ring beam wood and the ring beam aluminum, the ring beam decorative materials are snap-fitted and installed on the outer wall of the ring beam aluminum, which facilitates the disassembly between the ring beam decorative materials and the ring beam aluminum, and the ring beam aluminum is installed on the foundation column by bolts, which facilitates the connection between the ring beam aluminum and the foundation column, thereby ensuring the stability of the connection.

[0007] Furthermore, an installation groove is provided on the end surface of the ring beam wood of the aluminum-wood composite ring beam, the aluminum tenon is placed in the installation groove, and the aluminum tenon is fixed in the installation groove by a long screw, and the aluminum mortise is installed on the foundation column by bolts. The high-strength aluminum tenon is fixed in the installation groove of the aluminum-wood composite ring beam by a long screw, and the high-strength aluminum mortise is connected at the corresponding position of the foundation column by bolts. When the foundation column and the aluminum-wood composite ring beam are installed, the foundation column and the aluminum-wood composite ring beam are connected by mortise and tenon joints, the connection method is simple, and the connection effect is stable and not easy to fall off.

[0008] Furthermore, the aluminum mortise is composed of a mortise and a main body. The mortise and tenon is opened on one side surface of the main body. The mortise and tenon are provided in multiple groups, and the multiple groups of mortise and tenon are arranged in a stepped manner. A fixing hole is opened on the main body. The bolt passes through the fixing hole and then passes through the foundation column. The structures of the aluminum tenon and the aluminum mortise correspond to each other. After the aluminum tenon and the aluminum mortise and tenon are connected, expansion screws are installed at the connection. There are multiple groups of mortise and tenon, and the multiple groups of mortise and tenon are arranged in a stepped manner, which is convenient for high-strength connection between the wooden beam part and the foundation column.

At the same time, the steel pad is placed between the aluminum-wood composite corner post and the foundation column to protect the wood part of the aluminum-wood composite corner post and improve its service life.

[0010] Furthermore, the corner column aluminum material is installed on the foundation column by means of screws, and the screws extend into the inner side of the foundation column. The outer side of the corner column aluminum material is connected to the foundation ring beam by means of snaps. The corner column aluminum material is provided with a strip hole located on the outer side of the screw. Since the part connected to the concrete by the screw cannot be loosened, it is completely impossible to disassemble it if bolts are used. The part where the nut at the other end of the screw is not in the concrete can still be screwed. Space is reserved for the later maintenance and replacement of components of the wooden house, and the wooden house can even be dismantled and rebuilt with the original materials. Since the outer side of the corner column aluminum material is connected to the foundation ring beam by means of snaps, the tensile force of the structure is greatly improved.

[0011] Furthermore, the steel pad penetrates the aluminum mortise and aluminum-wood composite ring beam aluminum material through multiple sets of high-strength bolts. The steel pad further connects the aluminum-wood composite ring beam and the foundation column into a whole. At the same time, the steel pad protects the aluminum-wood composite corner column part, thereby increasing its service life.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] 1. The present invention uses long screws to fix high-strength aluminum tenons in the installation groove of the aluminum-wood composite ring beam, and uses bolts to connect high-strength aluminum mortises at the corresponding positions of the foundation columns. When the foundation columns and the aluminum-wood composite ring beam are installed, the foundation columns and the aluminum-wood composite ring beam are connected by mortise and tenon joints. The connection method is simple, and the connection effect is stable and not easy to fall off. At the same time, expansion screws are used to fix the connection between the aluminum tenon and the aluminum mortise, so that the connection strength of the aluminum tenon and the aluminum mortise is high.

[0014] 2. The present invention sets a steel pad on the top of the foundation column and the aluminum-wood composite ring beam, penetrates the high-strength bolt installation hole on the steel pad and then penetrates the aluminum mortise and tenon, and also penetrates the high-strength bolt installation hole on the steel pad and then penetrates the aluminum ring beam of the aluminum-wood composite ring beam with the aluminum mortise and tenon, so that the steel pad connects the foundation column and the aluminum-wood composite ring beam into a whole.

[0028] Furthermore, an installation groove 11 is opened on the end surface of the ring beam wood 3 of the aluminum-wood composite ring beam 2, and the aluminum tenon 12 is placed in the installation groove 11, and the aluminum tenon 12 is fixed in the installation groove 11 by a long screw 14, and the aluminum mortise 13 is installed on the foundation column 1 by a bolt 15.

[0029] Specifically, a high-strength aluminum tenon 12 is fixed in the installation groove 11 of the aluminum-wood composite ring beam 2 by using a long screw 14, and a high-strength aluminum mortise 13 is connected at the corresponding position of the foundation column 1 by using a bolt 15. When the foundation column 1 and the aluminum-wood composite ring beam 2 are installed, the foundation column 1 and the aluminum-wood composite ring beam 2 are connected by mortise and tenon joints. The connection method is simple, and the connection effect is stable and not easy to fall off.

[0030] Furthermore, the aluminum mortise 13 is composed of a mortise groove 19 and a main body 20. The mortise groove 19 is provided on one side surface of the main body 20. The mortise groove 19 is provided in multiple groups, and the multiple groups of mortise grooves 19 are arranged in a stepped manner. A fixing hole 21 is provided on the main body 20. The bolt 15 passes through the fixing hole 21 and then passes through the foundation column 1. The structures of the aluminum tenon 12 and the aluminum mortise 13 correspond to each other. After the aluminum tenon 12 and the aluminum mortise 13 are connected by mortise and tenon, an expansion screw is installed at the connection.

[0031] Specifically, multiple groups of mortise and tenon grooves 19 are provided, and the multiple groups of mortise and tenon grooves 19 are arranged in a stepped manner, which facilitates high-strength connection between the wooden beam part and the foundation column 1. After the aluminum tenon 12 and the aluminum mortise 13 are connected by mortise and tenon, expansion screws are installed at the connection, which improves the strength of the connection between the aluminum tenon 12 and the aluminum mortise 13. At the same time, the aluminum tenon 12 and the aluminum mortise 13 are fixed at the connection, so that the connection strength of the aluminum tenon 12 and the aluminum mortise 13 is high.

[0032] Furthermore, the aluminum-wood composite corner column 7 includes a corner column decorative material 8, a corner column timber 9 and a corner column aluminum material 10. The corner column timber 9 is installed on the corner column aluminum material 10 by means of wood screws 18. The corner column decorative material 8 is buckled on the corner column aluminum material 10. The corner column aluminum material 10 is installed on the ring beam aluminum material 4 of the aluminum-wood composite ring beam 2 by means of bolts 15. The corner column timber 9 is pressed onto the steel pad 6.

[0033] Specifically, by setting the steel pad 6 on the top of the foundation column 1 and the aluminum-wood composite ring beam 2, the high-strength bolt 17 is penetrated through the high-strength bolt 6 installation hole on the steel pad 6 and then through the aluminum mortise and tenon. At the same time, the high-strength bolt 17 is also penetrated through the high-strength bolt 6 installation hole on the steel pad 6 and then through the ring beam aluminum 4 of the aluminum-wood composite ring beam 2 with the aluminum mortise and tenon. Thus, the steel pad 6 connects the foundation column 1 and the aluminum-wood composite ring beam 2 into a whole. At the same time, the steel pad 6 is placed between the aluminum-wood composite corner column 7 and the foundation column 1, which protects the wood part of the aluminum-wood composite corner column 7 and improves its service life.

[0034] Furthermore, the corner column aluminum material 10 is installed on the foundation column 1 by means of a screw 22, and the screw 22 extends into the inner side of the foundation column 1, and the outer side of the corner column aluminum material 10 is connected to a foundation ring beam 23 by means of a snap-fit, and a strip hole 24 is opened on the corner column aluminum material 10 and is located on the outer side of the screw 22.

[0035] Specifically, since the part where the screw rod 22 is connected to the concrete cannot be loosened, the part where bolts are used cannot be disassembled at all, but the part where the nut at the other end of the screw rod 22 is not in the concrete can still be screwed, and space is reserved for the later maintenance and replacement of components of the wooden house, and the wooden house can even be dismantled and rebuilt using the original materials. Since the outer side of the corner column aluminum material 10 is connected to the foundation ring beam 23 by means of a snap-fit, the tensile force of the structure is greatly improved.

[0036] Furthermore, the steel pad 6 penetrates the aluminum mortise 13 and the ring beam aluminum material 4 of the aluminum-wood composite ring beam 2 through multiple groups of high-strength bolts 17.

[0037] Specifically, the steel pad 6 penetrates the aluminum mortise 13 and the ring beam aluminum material 4 of the aluminum-wood composite ring beam 2 through multiple sets of high-strength bolts 17. The steel pad 6 further connects the aluminum-wood composite ring beam 2 and the foundation column 1 into a whole. At the same time, the steel pad 6 protects the aluminum-wood composite corner column 7 and improves its service life.

[0038] It should be noted that, when the connection structure between the external angle column and the foundation column is working, the aluminum tenon 12 is installed in the installation groove 11 of the inner ring beam wood 3 of the aluminum-wood composite ring beam 2, and then the long screw 14 is passed through the aluminum tenon 12 and placed in the ring beam wood 3, the aluminum mortise 13 is buckled on the foundation column 1, and then the bolt 15 is passed through the fixing hole 21 of the aluminum tenon 13 and the installation hole of the foundation column 1 in sequence, and the aluminum tenon 13 is fixed on the foundation column 1 under the action of the bolt 15. When the foundation column 1 and the aluminum-wood composite ring beam 2 are assembled, the aluminum tenon 12 and the aluminum tenon 13 are butt-jointed to form a mortise and tenon structure, so that the foundation column 1 and the aluminum-wood composite ring beam 2 are installed and fixed. After the aluminum tenon 12 and the aluminum tenon 13 are butt-jointed, the expansion screw is driven into the connection between the aluminum tenon 12 and the aluminum tenon 13. This kind of Russian connection method is simple, and the foundation column 1 and the aluminum-wood composite ring beam 2 have a good stability effect after being connected, and are not easy to fall off;

[0039] Then, the steel pad 6 is pressed onto the foundation column 1 and the aluminum-wood composite ring beam 2, and then the high-strength bolt 17 is passed through the high-strength bolt installation hole 16 on the steel pad 6 and then through the aluminum mortise and tenon of the aluminum-wood composite ring beam 2. The high-strength bolt 17 is passed through the high-strength bolt installation hole 16 on the steel pad 6 and then through the aluminum mortise and tenon, so that the steel pad 6 connects the foundation column 1 and the aluminum-wood composite ring beam 2 into a whole, so that the entire connection is tight and has good stability;

[0040] When installing the aluminum-wood composite corner column 7, the corner column aluminum material 10 is installed on the ring beam aluminum material 4 of the aluminum-wood composite ring beam 2 by bolts 15, and at the same time, the corner column wood material 9 is pressed on the steel backing plate 6;

[0041] Since the screw rod 22 extends into the inner side of the foundation column 1, the foundation column 1 needs to be poured with concrete after the connection is completed, and the screw rod 22 reserved in the foundation column 1 will be bonded to the concrete. Since the part connected with the screw rod 22 and the concrete cannot be loosened, it is completely impossible to disassemble it with bolts. The nut at the other end of the screw rod 22 that is not in the concrete can still be screwed, and space is reserved for the later maintenance and replacement of the components of the wooden house, and even the wooden house can be dismantled and rebuilt with the original materials. Since the outer side of the corner column aluminum material 10 is connected to the foundation ring beam 23 by means of a snap, the pulling force of the structure is greatly improved, and the steel pad 6 can be used to protect the wood part of the aluminum-wood composite corner column 7 to increase its service life.
