Description

Technical Field

[0001] The utility model relates to the technical field of steel-wood combination, in particular to a steel-wood connection structure. Background Art

[0002] Steel and timber composite construction offers numerous advantages in architecture and engineering. Steel provides high strength and stability, while timber reduces the overall weight of the structure, resulting in a sturdy yet lightweight structure. The most cost-effective material connection method can be selected based on project requirements. While timber is cheaper than steel, steel provides greater support and reduces the number of columns, thus saving overall costs. Existing techniques use steel plates and bolts to secure steel-timber structures. While this provides good structural stability and connection strength, the bolt holes become stress concentration points, making them susceptible to material fatigue or cracking, particularly under heavy loads or impact. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a steel-wood connection structure, which solves the technical problem in the prior art that the steel-wood connection structure may cause fatigue cracking of the wood due to bolt connection.

[0007] The steel component includes a steel plate and two limit blocks rotatably arranged on opposite end surfaces of the steel plate. The steel plate is arranged in the fixing groove, and the two limit blocks are in one-to-one contact with the closed end of the installation groove.

[0008] Preferably, the fixing groove is provided with a plurality of first mortises, and the steel plate is provided with a plurality of first tenons, and the first tenons extend into the first mortises one by one.

[0009] Preferably, a connecting rod is rotatably provided between the steel plate and the limiting block, and the limiting block abuts against the closed end of the installation groove through the connecting rod.

[0010] Preferably, the steel plate and the limiting block are both provided with lifting ears, and both ends of the connecting rod are hinged to the corresponding lifting ears respectively.

[0011] Preferably, a fixing column is provided along the length direction of the wooden column, and the fixing column is arranged parallel to the limiting block and the steel plate.

[0012] Preferably, the closed end of the mounting groove is provided with a second mortise, and the limiting block is provided with a second tenon, and the second tenon extends into the second mortise.

[0013] Preferably, the height of the mounting groove is lower than that of the fixing groove, so that when the steel plate is installed in the fixing groove and the limit block is linked to the closed end of the mounting groove by the connecting rod, the wooden column, the steel plate and the limit block are level with each other.

[0014] Compared with the existing technology, the utility model has the following beneficial effects: during assembly, the steel plate is placed in the fixing groove of the wooden column, and the two limit blocks are respectively in contact with the closed ends of the installation grooves on the wooden column.

[0021] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] See also Figures 1 to 5The utility model provides a steel-wood connection structure, comprising:

[0023] A wooden column 1 has a width direction and a length direction, a fixing groove 2 is provided in the width direction, and two installation grooves 3 are provided at intervals in the length direction, and the installation grooves 3 have an open end and a closed end that are arranged in opposite directions;

[0024] The steel component includes a steel plate 4 and two limit blocks 5 rotatably arranged on opposite end surfaces of the steel plate 4. The steel plate 4 is arranged in the fixing groove 2, and the two limit blocks 5 are in one-to-one correspondence with the closed end of the installation groove 3.

[0025] In this embodiment, the wooden column 1 has a width direction and a length direction, a fixing groove 2 is provided in the width direction of the wooden column 1, and two installation grooves 3 are provided at intervals in the length direction of the wooden column 1. The two installation grooves 3 are located on the left and right sides of the fixing groove 2, and the installation groove 3 has an open end and a closed end that are arranged opposite to each other. When installing, the steel plate 4 is placed in the fixing groove 2 of the wooden column 1, and the two limit blocks 5 are rotatably connected to the steel plate 4, so that the two limit blocks 5 are each moved from the corresponding open end of the installation groove 3 to the closed end of the installation groove 3. When the limit block 5 abuts against the installation groove 3, the steel plate 4 is placed in the fixing groove 2 of the wooden column 1. After the end is closed, the steel plate 4 can be prevented from sliding out of the fixing groove 2, which can ensure a tight connection between the wood and the steel and provide good structural stability. The two limit blocks 5 are rotatably connected to the steel plate 4, which increases the connection support range with the wooden column 1 and improves the strength of the connection between the wooden column 1 and the steel plate 4. Compared with the traditional steel-wood composite structure that uses bolts to connect wood and steel structures, this solution can avoid the situation where when the wood is subjected to load and rotates, the bolt hole is subjected to excessive pressure, resulting in stress concentration and easy fatigue cracking of the wood.

[0026] The fixing groove 2 is provided with a plurality of first mortises 201 , and the steel plate 4 is provided with a plurality of first tenons 401 , and the first tenons 401 extend into the first mortises 201 in a one-to-one correspondence.

[0027] In this embodiment, a plurality of first mortises are provided in the fixing groove 2 of the wooden column 1, and corresponding first tenons 401 are provided on the steel plate 4. During installation, the first tenons 401 on the steel plate 4 are inserted into the first mortises 201 in the fixing groove 2 of the wooden column 1, forming a mechanical locking connection. This not only increases the connection strength but also improves the overall stability of the structure. The mortise and tenon connection not only provides a secure connection without the need for additional fasteners (such as bolts), but also helps distribute stress and reduce damage to the wooden column 1 caused by external forces.

[0028] A connecting rod 6 is rotatably provided between the steel plate 4 and the limiting block 5 , and the limiting block 5 abuts against the closed end of the installation groove 3 through the connecting rod 6 .

[0029] In this embodiment, the steel plate 4 and the limit block 5 are rotationally connected through the connecting rod 6. During installation, when the steel plate 4 is placed in the fixing groove 2 of the wooden column 1, the two limit blocks 5 can rotate and move from the open end of the installation groove 3 to abut the closed end of the installation groove 3 through the action of the connecting rod 6, so that the limit block 5 can be more easily installed in the installation groove 3. When the limit block 5 reaches the closed end of the installation groove 3 and abuts, it can effectively prevent the steel plate 4 from moving in the length direction. The cooperation between the first mortise 201 and the first tenon 401 can limit the movement of the steel plate 4 in the width direction, thereby enhancing the stability and tensile strength of the entire connection structure between the wooden column 1 and the steel plate 4.

[0030] The steel plate 4 and the limiting block 5 are both provided with lifting ears, and both ends of the connecting rod 6 are hinged to the corresponding lifting ears respectively.

[0031] In this embodiment, the two ends of the connecting rod 6 are respectively connected to the corresponding ears on the steel plate 4 and the limit block 5 in a hinged manner. The connecting rod 6 is equivalent to a rotating shaft, allowing the limit block 5 to rotate relative to the steel plate 4. The angle of the limit block 5 can be adjusted during the installation process to facilitate its installation in the installation groove 3. When the limit block 5 is rotated into place and abuts against the closed end of the installation groove 3, it provides stable support to prevent the steel plate 4 from sliding along the length direction. The connecting rod 6 can withstand large torque and tension to ensure the reliability of the connection.

[0032] A fixing column 7 is provided along the length direction of the wooden column 1 , and the fixing column 7 is arranged parallel to the limiting block 5 and the steel plate 4 .

[0033] In this embodiment, the fixing column 7 is arranged along the length direction of the wooden column 1. It passes through the wooden column 1 and is arranged parallel to the limit block 5 and the steel plate 4. The existence of the fixing column 7 can increase the longitudinal stability of the entire structure and prevent deformation or movement due to external force. The fixing column 7 can serve as an additional fixing point and work together with the existing steel-wood connection structure to provide more reliable support. It can be understood that the fixing point position of the fixing column 7 should be set at the position of the two limit blocks 5, and the two ends of the fixing column 7 are respectively connected to the limit blocks 5 using nuts to prevent the free rotation of the fixing column 7.

[0034] In addition, when the steel-wood connection structure in this solution is used as a column, steel components can be set at the opposite ends of the wooden column 1, such as Figure 5 As shown, the fixed column 7 is removed, and the steel components at the opposite ends of the wooden column 1 are connected by the tension rod 8. When the steel-wood connection structure is used as a seat column and is subjected to gravity, the gravity is fed back to the steel plate 4 through the connecting rod 6. The two steel plates 4 are connected by the tension rod 8. Therefore, most of the gravity is dispersed on the steel plate 4 and the tension rod 8, ensuring the strength and stability of the connection between the steel plate 4 and the wooden column 1.

[0035] A second mortise 301 is provided at the closed end of the mounting groove 3 , and a second tenon 501 is provided at the limiting block 5 . The second tenon 501 extends into the second mortise 301 .

[0036] In this embodiment, in order to ensure a tight connection between the two limit blocks 5 and the wooden column 1, a second mortise 301 is provided at the closed end of the installation groove 3, and the limit block 5 is provided with a second tenon 501. When the limit block 5 abuts against the closed end of the installation groove 3, the second tenon 501 is inserted into the second mortise 301, and then through the cooperation of the connecting rod 6, the movement of the steel plate 4 and the two limit blocks 5 is restricted.

[0037] The height of the mounting groove 3 is lower than that of the fixing groove 2, so that when the steel plate 4 is installed in the fixing groove 2 and the limit block 5 is linked to abut against the closed end of the mounting groove 3 by the connecting rod 6, the wooden column 1, the steel plate 4 and the limit block 5 are level with each other.

[0038] When the fixing groove 2 is in the state of being lowered, the top edge of the fixing groove 3 is lowered to the top edge of the fixing groove 2. When the fixing groove 2 is in the state of being lowered, the top edge of the fixing groove 3 is lowered to the top edge of the fixing groove 2. When the fixing groove 2 is in the state of being lowered, the top edge of the fixing groove 3 is lowered to the top edge of the fixing groove 2. When the fixing groove 2 is in the state of being lowered, the top edge of the fixing groove 3 is lowered to the top edge of the fixing groove 2. When the fixing groove 2 is in the state of being lowered, the top edge of the fixing groove 3 is lowered to the top edge of the fixing groove 2.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
