Description

Technical Field

[0001] The utility model relates to a building connection structure, more specifically, it relates to a flowering column connection node. Background Art

[0002] Currently in the wood structure construction industry, due to the limitations of processing machinery in glued wood factories, it is impossible to accurately size the cross-section of polygonal wood columns. The processed end faces often deviate from the design dimensions, and there are also large and small heads. This often results in the inability of the integrated polygonal hardware to slide from the top of the column to the predetermined position. On-site correction of the wood columns requires a lot of labor costs and the appearance does not meet the design requirements.

[0003] There is no record of opening a flower column connection node in the existing patent literature. For the connection between the polygonal wooden column and the wooden beam, an integrated embracing polygonal hardware is usually used. The factory opens a bolt hole at the predetermined position of the wooden column. After the hardware slides from the top of the column to the predetermined position, the hardware is fastened to the glued wooden column with bolts. The hardware often cannot slide smoothly to the predetermined position. The hardware is large and bulky. Its specific installation method limits the construction sequence and is not conducive to on-site installation. This node form requires multi-directional through bolts, which greatly weakens the strength of the wooden column node position. At the same time, due to the inaccurate cross-sectional dimensions of the wooden column, the actual production needs to expand the opening diameter, which will further weaken the strength of the wooden column connection position. Utility Model Content

[0004] The utility model overcomes the problems of complex connection between existing plywood columns and wooden beams and weakened strength of wooden columns, and provides a flower column connection node. This scheme realizes the connection between plywood columns and beams without reducing the strength of the connection position of the plywood columns, and the connection method is simple.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a flowering column connection node, including a wooden column, and also including a split connection component, the wooden column is provided with a split connection groove on its circumference, the split connection component includes a first split connection piece and a second split connection piece, the first split connection piece and the second split connection piece are adapted to the circumference of the wooden column, and are embedded in the split connection groove. In this solution, the split connection component is divided into two units, the first split connection piece and the second split connection piece, which reduces the volume and weight, makes the construction site more convenient, and allows the installation sequence to be flexibly adjusted without restrictions; and a split connection groove is provided on the wooden column, thereby avoiding the problem of the split connection component not being installed in place, and at the same time, the split connection groove has a certain load-bearing capacity for the split connection component, which can reduce the tangential pressure of the positioning piece or the fixing piece on the wooden column and improve the connection strength.

[0006] Preferably, the split connection assembly includes a polygonal cylinder, and the polygonal cylinder on the first split connection piece and the polygonal cylinder on the second split connection piece are both provided with a plurality of connection plates. The polygonal cylinder on the split connection assembly can be adapted to a polygonal wooden column structure, and the connection plates on the first split connection piece and the second split connection piece can cooperate with structures such as wooden beams to achieve connection between wooden columns and other structures.

[0007] Preferably, a plurality of positioning holes are arranged between the connecting plates and on the polygonal cylindrical surface. The connecting plate is arranged in the middle of the polygonal cylindrical surface, and the positioning holes are arranged on both sides of the connecting plate, thereby improving the connection stability and connection strength of the split connection assembly on the wooden column.

[0008] Preferably, the first split connector and the second split connector are fixed by welding. The first split connector and the second split connector are fixed by welding to improve the connection strength.

[0009] As a preference, it further comprises a glued wood beam, on which a connection groove is provided to match the connection plate. The connection groove on the glued wood beam can be matched and connected with the connection plate, so that the glued wood beam can be connected to the wood column body.

[0010] Preferably, the connecting plate is provided with a first connecting hole, the glulam beam is provided with a second connecting hole corresponding to the first connecting hole, and the first connecting hole and the second connecting hole are connected by a second fixing member. The first connecting hole and the second connecting hole are used for connecting the connecting plate and the glulam beam, that is, the wooden column and the glulam beam can be fixedly connected, wherein the second fixing member can be a steel pin.

[0011] Preferably, the wooden column and the split connection assembly are connected via a first fixing member, and the first fixing member matches the positioning hole. The first fixing member can be a wood screw, which fixes the wooden column and the split connection assembly.

[0012] Preferably, the positioning holes on adjacent planes are staggered. The first fixing members need to be installed in the positioning holes, and in order to prevent the first fixing members in different positioning holes from interfering with each other, the positioning holes need to be staggered.

[0013] Preferably, two groups of positioning holes are provided on the same plane, and the two groups of positioning holes are respectively provided on both sides of the connecting plate. The positioning holes are provided in two groups, which can improve the connection strength between the split connecting assembly and the wooden column, and the two groups of positioning holes are also respectively provided on both sides of the connecting plate, thereby improving the connection stability between the split connecting assembly and the wooden column.

[0014] Preferably, the outer surface of the polygonal cylinder is flush with the surface of the split connection groove of the wooden column. The polygonal cylinder on the split connection component is flush with the notch surface of the split connection groove on the wooden column, so that the split connection component can be completely embedded in the split connection groove, so that the split connection component is not exposed, thereby improving the aesthetics.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0023] Example 1: Figure 1 to Figure 2A flower column connection node shown includes a wooden column 1 structure and a split connection component 2. The wooden column 1 structure is a hexagonal prism structure, and the wooden column 1 structure is a glued wooden column. A split connection groove 3 is arranged in the circumference of the wooden column 1, and the split connection component 2 includes a first split connection piece 2.1 and a second split connection piece 2.2. The first split connection piece 2.1 and the second split connection piece 2.2 are two identical structures, and the first split connection piece 2.1 and the second split connection piece 2.2 are also cylindrical structures. The first split connection piece 2.1 and the second split connection piece 2.2 can cooperate together to form a hexagonal closed-loop cylindrical structure, that is, a polygonal cylinder 4 is arranged on the first split connection piece 2.1 and the second split connection piece 2.2.

[0024] By splitting the split connection component 2 into two connection units, the problem that the embracing polygonal hardware cannot slide from the top of the column to the predetermined position is avoided, and the production accuracy requirements of the wooden column 1 structure can be greatly reduced.

[0025] Specifically, taking the first split connector 2.1 as an example, the polygonal cylinder 4 includes two types: a complete cylinder 4.1 and a half cylinder 4.2. The two ends of the first split connector 2.1 are half cylinders 4.2, and the middle is two complete cylinders 4.1; when the first split connector 2.1 and the second split connector 2.2 are matched, the half cylinder 4.2 on the first split connector 2.1 can form a complete cylinder 4.1 with the half cylinder 4.2 on the second split connector 2.2, thereby forming a closed hexagonal cylinder structure.

[0026] The polygonal cylinder 4 on the first split connector 2.1 and the polygonal cylinder 4 on the second split connector 2.2 are metal parts to ensure that the first split connector 2.1 and the second split connector 2.2 have sufficient strength. The thickness of the polygonal cylinder 4 of the first split connector 2.1 and the second split connector 2.2 shall not exceed the groove depth of the split connection groove 3 on the wooden column 1 structure. In this embodiment, the thickness of the polygonal cylinder 4 of the first split connector 2.1 and the second split connector 2.2 is designed to be the same as the groove depth of the split connection groove 3 on the wooden column 1 structure, that is, the outer surface of the polygonal cylinder 4 can be flush with the notch surface of the split connection groove 3, so that the surface of the wooden column 1 structure is relatively flat, thereby improving the aesthetics of the wooden column 1 structure.

[0027] A connecting plate 5 structure is also provided on the polygonal cylinder 4 on the first split connecting member 2.1 and the second split connecting member 2.2. Since the polygonal cylinder 4 is divided into two types, in this solution, the structure of the connecting plate 5 is also divided into two types, which are defined as an intermediate connecting plate 5.1 and a side connecting plate 5.2. Taking the first split connecting member 2.1 as an example (the second split connecting member 2.2 is the same), the intermediate connecting plate 5.1 is arranged on the complete cylinder 4.1, and the intermediate connecting plate 5.1 is arranged in the middle position of the complete cylinder 4.1; and the side connecting plate 5.2 is arranged on half of the cylinder 4.2, and the side connecting plate 5.2 is arranged at the side position of the half of the cylinder 4.2, and the thickness of the intermediate connecting plate 5.1 is twice the thickness of the side connecting plate 5.2. Similarly, when the first split connector 2.1 and the second split connector 2.2 are matched, the two side connecting plates 5.2 can fit together, so that the fitting thickness of the two side connecting plates 5.2 can reach the thickness of an intermediate connecting plate 5.1, that is, when the first split connector 2.1 and the second split connector 2.2 are matched, the thickness of all the connecting plates 5 are the same.

[0028] It should be noted that the first split connector 2.1 and the second split connector 2.2 are fixed by welding. Specifically, the side connecting plate 5.2 on the first split connector 2.1 and the side connecting plate 5.2 on the second split connector 2.2 are welded to complete the fixed combination. The welding fixation can improve the connection strength of the two.

[0029] Several groups of positioning holes 6 are also provided on the polygonal cylindrical surface 4 of the first split connector 2.1 and the second split connector 2.2. The positioning holes 6 are evenly distributed on the polygonal cylindrical surface 4 of the first split connector 2.1 and the second split connector 2.2. Specifically, the positioning holes 6 on the same vertical line are a group, and each group of positioning holes 6 is set to three. Six groups of positioning holes 6 are respectively provided on the first split connector 2.1 and the second split connector 2.2, wherein two groups of positioning holes 6 are provided on the complete cylindrical surface 4.1, and each group of positioning holes 6 is respectively provided on both sides of the middle connecting plate 5.1, and one group of positioning holes 6 is provided on the half cylindrical surface 4.2. After the first split connector 2.1 and the second split connector 2.2 cooperate to form a closed hexagonal prism surface, there are two groups of positioning holes 6 on each polygonal cylindrical surface 4, and there are two groups of positioning holes 6 on both sides of the connecting plate 5.

[0030] The first fixing member 11 can be assembled in the positioning hole 6. Specifically, the first fixing member 11 is a wood screw. By assembling the wood screw, the first split connector 2.1 and the second split connector 2.2 can be fixed on the wooden column 1. When the first split connector 2.1 and the second split connector 2.2 are matched on the wooden column 1, under the action of gravity, the split connection groove 3 has a certain load-bearing effect on the first split connector 2.1 and the second split connector 2.2, thereby reducing the tangential pressure of the wood screw on the wooden column 2 and improving the connection strength.

[0031] It should also be noted that the height positions of the positioning holes 6 on the same polygonal cylinder 4 are flush with each other, while the height positions of the positioning holes 6 on adjacent polygonal cylinders 4 need to be staggered; when the wood screws are driven into the structure of the wooden column 1, the wood screws on the adjacent polygonal cylinders 4 will not interfere with each other. Similarly, in order to prevent the wood screws on the separated polygonal cylinders 4 (one polygonal cylinder is separated from another polygonal cylinder by one polygonal cylinder) from interfering with each other, the positioning holes 6 on the separated polygonal cylinders 4 can also be designed with staggered distribution, and the positioning holes 6 on the opposite polygonal cylinders 4 can be designed with equal heights. When the two groups of positioning holes 6 are in relative positions on the split connection component 1, the distance at this time is the largest, and the wood screws will not interfere with each other.

[0032] Example 2: Figures 1 to 5 A flower column connection node shown includes a wooden column 1 structure and a split connection component 2. The wooden column 1 structure is a hexagonal prism structure, and the wooden column 1 structure is a glued wooden column. A split connection groove 3 is arranged in the circumference of the wooden column 1, and the split connection component 2 includes a first split connection piece 2.1 and a second split connection piece 2.2. The first split connection piece 2.1 and the second split connection piece 2.2 are two identical structures, and the first split connection piece 2.1 and the second split connection piece 2.2 are also cylindrical structures. The first split connection piece 2.1 and the second split connection piece 2.2 can cooperate together to form a hexagonal closed-loop cylindrical structure, that is, a polygonal cylinder 4 is arranged on the first split connection piece 2.1 and the second split connection piece 2.2.

[0033] By splitting the split connection component 2 into two connection units, the problem that the embracing polygonal hardware cannot slide from the top of the column to the predetermined position is avoided, and the production accuracy requirements of the wooden column 1 structure can be greatly reduced.

[0034] Specifically, taking the first split connector 2.1 as an example, the polygonal cylinder 4 includes two types: a complete cylinder 4.1 and a half cylinder 4.2. The two ends of the first split connector 2.1 are half cylinders 4.2, and the middle is two complete cylinders 4.1; when the first split connector 2.1 and the second split connector 2.2 are matched, the half cylinder 4.2 on the first split connector 2.1 can form a complete cylinder 4.1 with the half cylinder 4.2 on the second split connector 2.2, thereby forming a closed hexagonal cylinder structure.

[0035] The polygonal cylinder 4 on the first split connector 2.1 and the polygonal cylinder 4 on the second split connector 2.2 are metal parts, ensuring that the first split connector 2.1 and the second split connector 2.2 have sufficient strength. The thickness of the polygonal cylinder 4 of the first split connector 2.1 and the second split connector 2.2 shall not exceed the groove depth of the split connection groove 3 on the wooden column 1 structure. In this embodiment, the thickness of the polygonal cylinder 4 of the first split connector 2.1 and the second split connector 2.2 is designed to be slightly smaller than the groove depth of the split connection groove 3 on the wooden column 1 structure. Specifically, the thickness of the polygonal cylinder 4 is 2 mm less than the groove depth of the split connection groove 3. When the glued wood beam 7 is connected with the connecting plate 5, the glued wood beam 7 can be tightly matched with the wooden column 1 to avoid the glued wood beam 7 and the wooden column 1 from being separated. In addition, the glued wood beam 7 can also block the polygonal cylinder 4, so that the surface of the wooden column 1 structure is relatively flat, improving the aesthetics of the wooden column 1 structure.

[0036] A connecting plate 5 structure is also provided on the polygonal cylinder 4 on the first split connector 2.1 and the second split connector 2.2, and the connecting plate 5 can be used to connect the glued laminated wood beam 7; wherein, since the polygonal cylinder 4 is divided into two types, in this solution, the structure of the connecting plate 5 is also divided into two types, which are defined as an intermediate connecting plate 5.1 and a side connecting plate 5.2 respectively. Taking the first split connector 2.1 as an example (the second split connector 2.2 is the same), the intermediate connecting plate 5.1 is arranged on the complete cylinder 4.1, and the intermediate connecting plate 5.1 is arranged in the middle position of the complete cylinder 4.1; and the side connecting plate 5.2 is arranged on half of the cylinder 4.2, and the side connecting plate 5.2 is arranged at the side position of the half of the cylinder 4.2, and the thickness of the intermediate connecting plate 5.1 is twice the thickness of the side connecting plate 5.2. Similarly, when the first split connector 2.1 and the second split connector 2.2 are matched, the two side connecting plates 5.2 can fit together, so that the fitting thickness of the two side connecting plates 5.2 can reach the thickness of an intermediate connecting plate 5.1, that is, when the first split connector 2.1 and the second split connector 2.2 are matched, the thickness of all the connecting plates 5 are the same.

[0037] It should be noted that the first split connector 2.1 and the second split connector 2.2 are fixed by welding. Specifically, the side connecting plate 5.2 on the first split connector 2.1 and the side connecting plate 5.2 on the second split connector 2.2 are welded to complete the fixed combination. The welding fixation can improve the connection strength of the two.

[0038] Several groups of positioning holes 6 are also provided on the polygonal cylindrical surface 4 of the first split connector 2.1 and the second split connector 2.2. The positioning holes 6 are evenly distributed on the polygonal cylindrical surface 4 of the first split connector 2.1 and the second split connector 2.2. Specifically, the positioning holes 6 on the same vertical line are a group, and each group of positioning holes 6 is set to three. Six groups of positioning holes 6 are respectively provided on the first split connector 2.1 and the second split connector 2.2, wherein two groups of positioning holes 6 are provided on the complete cylindrical surface 4.1, and each group of positioning holes 6 is respectively provided on both sides of the middle connecting plate 5.1, and one group of positioning holes 6 is provided on the half cylindrical surface 4.2. After the first split connector 2.1 and the second split connector 2.2 cooperate to form a closed hexagonal prism surface, there are two groups of positioning holes 6 on each polygonal cylindrical surface 4, and there are two groups of positioning holes 6 on both sides of the connecting plate 5.

[0039] The first fixing member 11 can be assembled in the positioning hole 6. Specifically, the first fixing member 11 is a wood screw. By assembling the wood screw, the first split connector 2.1 and the second split connector 2.2 can be fixed on the wooden column 1. When the first split connector 2.1 and the second split connector 2.2 are matched on the wooden column 1, under the action of gravity, the split connection groove 3 has a certain load-bearing effect on the first split connector 2.1 and the second split connector 2.2, thereby reducing the tangential pressure of the wood screw on the wooden column 2 and improving the connection strength.

[0040] It should also be noted that the height positions of the positioning holes 6 on the same polygonal cylinder 4 are flush with each other, while the height positions of the positioning holes 6 on adjacent polygonal cylinders 4 need to be staggered; when the wood screws are driven into the structure of the wooden column 1, the wood screws on the adjacent polygonal cylinders 4 will not interfere with each other. Similarly, in order to prevent the wood screws on the separated polygonal cylinders 4 (one polygonal cylinder is separated from another polygonal cylinder by one polygonal cylinder) from interfering with each other, the positioning holes 6 on the separated polygonal cylinders 4 can also be designed with staggered distribution, and the positioning holes 6 on the opposite polygonal cylinders 4 can be designed with equal heights. When the two groups of positioning holes 6 are in relative positions on the split connection component 1, the distance at this time is the largest, and the wood screws will not interfere with each other.

[0041] like Figure 3As shown, two groups of first connecting holes 9 are provided on the connecting plate 5, and a connecting groove 8 is provided on the glued wood beam 7. Since the vertical length of the connecting plate 5 is the same as the vertical length of the polygonal cylinder 4, the vertical length of the connecting groove 8 also needs to be the same as that of the connecting plate 5, or slightly larger than the length of the connecting plate 5, to ensure that the connecting plate 5 will not be exposed and affect the aesthetic effect.

[0042] The connection groove 8 is provided with a second connection hole 10 corresponding to the position of the first connection hole 9. When the glued wood beam 7 is matched with the connection plate 5, the positions of the first connection hole 9 and the second connection hole 10 can be aligned. At this time, the second fixing member 12 can be used to connect the glued wood beam 7 and the connection plate 5 together. Specifically, the second fixing member 12 can be a steel pin or a screw structure.
