Description

Technical Field

[0001] This invention belongs to the field of timber frame tenon removal and reinforcement construction technology, specifically relating to a beam dragging reinforcement construction method for timber frame tenon removal. Background Technology

[0002] Traditional timber-framed buildings are a precious cultural heritage of my country. These buildings form a stable structure through the ingenious riveting of timber. Most of them use a large timber frame as the main body to support the entire building. The timber frame building with mortise and tenon joints has a certain deformation energy dissipation and earthquake resistance.

[0003] However, with the passage of time and the impact of earthquakes, under long-term environmental erosion and external forces, timber-framed buildings are prone to joint loosening and structural warping. Large timber structures can be eroded and damaged, and many timber-framed dwellings experience tenon pull-out at joints, with some even experiencing complete tenon detachment. How to restore and reinforce these structures has become a key technical issue restricting building safety. Currently, commonly used reinforcement methods include reinforcing tenon joints with flat steel and carbon fiber cloth. However, these methods are only effective for joints with minor pull-out; their reinforcement effect on joints with large pull-out or detachment is negligible. Therefore, research on repair and construction methods for timber-framed buildings is particularly important.

[0004] Therefore, there is an urgent need for a scientific and reasonable method to reinforce this type of earthquake damage. Summary of the Invention

[0005] The technical problem this invention aims to solve is to address the shortcomings of the prior art by providing a method for reinforcing timber frames by removing the original tenons. This method involves cutting off the original tenons of the timber beams and machining fixed tenons to provide space for the installation of the beam supports. A staggered joint is created by cutting the top of the timber columns to facilitate beam support installation. A mortise corresponding to the fixed tenons is machined on the protrusion of the first module of the beam support, ensuring a stable connection between the timber beam and the timber column. Finally, a first steel sleeve is installed and glue is injected to complete the removal and reinforcement of the timber beam and timber column. This reinforcement method is simple, practical, and has good load-bearing capacity, providing technical support for subsequent reinforcement treatment of this type of earthquake damage.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a method for reinforcing beams with dislocated tenons in timber frames, characterized in that the method includes the following steps: Step 1: Support the dislodged wooden beams and pillars; Step 2: Cut off the original tenons of the wooden beams and pillars that were used for support in Step 1, and then process fixed tenons at the ends of the wooden beams where the original tenons were cut off to obtain wooden beams with fixed tenons. Step 3: Cut the column head of the wooden column corresponding to the wooden beam with fixed tenon obtained in Step 2 to obtain the wooden beam with fixed tenon and the wooden column with staggered joint; Step 4: Based on the wooden beam with fixed tenons and the wooden column with staggered joints obtained in Step 3, process the beam support; the beam support is composed of a semi-circular first module and a semi-circular second module assembled by mortise and tenon joints. The two ends of the first module are respectively processed with a first tenon and a first mortise. The two ends of the second module are respectively processed with a second mortise and a second tenon corresponding to the first tenon and the first mortise. The protruding part of the first module is processed with a fixed mortise corresponding to the fixed tenon. Step 5: Install the beam truss processed in Step 4 onto the staggered wooden column obtained in Step 3, and then combine the fixed tenon of the wooden beam with the fixed mortise of the beam truss to obtain the initial fixed structure. Step Six: The beam support in the initial fixed structure obtained in Step Five is reinforced with a first steel sleeve, and glue is injected into the gap between the beam support and the first steel sleeve to obtain the wooden beam and wooden column that have been completed and reinforced by detachment.

[0007] This invention first supports the dislocated wooden beams and columns to prevent them from collapsing and to facilitate subsequent construction. The original tenons of the wooden beams are cut off to provide space for the installation of the beam support. Tenons are machined and fixed at the ends of the wooden beams to facilitate mortise and tenon joints with the beam support. The column heads are cut to create a staggered platform with a thinner top and thicker bottom, making it easier to mount the beam support on the column heads. The beam support is assembled by riveting the first and second modules together, making it easy to fit onto the column heads with a stable structure. The first module has a mortise corresponding to the fixed tenon, ensuring a secure connection between the wooden beam and the column. Finally, the first steel sleeve is installed and glue is injected to complete the reinforcement of the dislocated wooden beams and columns.

[0008] The above-mentioned method for reinforcing beams with dislocated tenons in a timber frame is characterized in that the support in step one is provided using scaffolding pipes. This invention uses scaffolding pipes for support, which provides stable support, facilitates construction, and reduces costs.

[0009] The above-mentioned method for reinforcing beams with disassembled tenons in a timber frame is characterized in that, in step two, the original tenons cut off are used to fill the original mortises of the timber columns, and glue is injected for reinforcement. This invention fills the original mortises with the original tenons, ensuring the structural strength of the timber columns and improving the reinforcement effect, while also achieving waste utilization, making it economical and environmentally friendly.

[0010] The above-mentioned method for reinforcing timber frame beams by dismantling tenons is characterized in that the cutting in step three is a circular cutting, with a cutting thickness of 1 / 9 to 1 / 7 of the timber column diameter and a cutting height of 1.8 to 2.2 times the timber beam height. This invention ensures that the subsequently installed beams are coaxial with the timber column through circular cutting, improving the stability of the reinforcement. By controlling the cutting thickness, the width of the misalignment is controlled, ensuring that the beams are stably fitted onto the ends of the timber column, preventing the beams from slipping due to insufficient cutting thickness and the structural strength of the top of the timber column from decreasing due to excessive cutting thickness.

[0011] The above-mentioned method for reinforcing timber frames with detached tenons using beam supports is characterized in that, in step four, the height of the beam support is the same as the height at which the column head is cut; the height of the fixing mortise is the same as the height of the fixing tenon; the diameter of the central hole of the beam support is the same as the diameter of the column head after cutting; and the circumference width of the beam support is 8cm to 10cm larger than the length of the fixing tenon. This invention, by controlling the height of the beam support to be the same as the height at which the column head is cut, ensures that the beam support fits completely onto the column head. By controlling the height of the fixing mortise to be the same as the height of the fixing tenon, and because the height of the beam support is greater than the height of the timber beam, the lower part of the fixing mortise is a solid structure, providing support for the fixing tenon and enhancing the effect of detached tenon reinforcement between the timber beam and column. By controlling the diameter of the central hole of the beam support to be the same as the diameter of the column head after cutting, a stable connection between the beam support and the column head is facilitated. By controlling the circumference width of the beam support, a stable connection between the fixing tenon and the beam support is ensured, further enhancing the effect of detached tenon reinforcement between the timber beam and column.

[0012] The above-mentioned method for reinforcing timber frame beams by removing tenons is characterized in that, in step four, the root width of the first and second tenons is 1 / 3 to 1 / 4 of the beam support ring width, and the end width of the first and second tenons is 1 / 2 to 1 / 3 of the beam support ring width. This invention, by controlling the parameters of the first and second tenons, ensures the stability of the beam support and enhances the effect of reinforcing timber beams and columns by removing tenons.

[0013] The above-mentioned method for reinforcing a timber frame with a disassembled beam is characterized in that, in step six, the first steel sleeve is tightened with M12 high-strength bolts. The height of the first steel sleeve is the height of the beam sleeve minus the height of the timber beam, and its thickness is 5mm to 8mm. In this invention, since the height of the beam sleeve is greater than the height of the timber beam, and the upper part of the beam sleeve is connected to the timber beam, the first steel sleeve is only fitted onto the lower part of the beam sleeve. By using M12 high-strength bolts and controlling the dimensions of the first steel sleeve, stable reinforcement of the beam sleeve is ensured, enhancing the effect of the disassembled timber beam and timber column reinforcement.

[0014] The above-mentioned method for reinforcing timber frame beams by dislocating tenons is characterized in that, in step six, a second steel sleeve is installed on the upper part of the timber columns in the timber beams and columns that have undergone dislocating reinforcement. The second steel sleeve is fastened with M12 high-strength bolts, and its height is the same as the height of the timber beam, with a thickness of 5mm to 8mm. This invention, by setting the second steel sleeve, prevents the beam from crushing and splitting the timber columns below the misalignment, thus enhancing the effect of dislocating and reinforcing the timber beams and columns.

[0015] Compared with the prior art, the present invention has the following advantages: 1. This invention first supports the dislocated wooden beams and columns to prevent them from collapsing and facilitates subsequent construction. The original tenons of the wooden beams are cut off to provide space for the installation of the beam support. Tenons are machined and fixed at the ends of the wooden beams to facilitate mortise and tenon joints with the beam support. The column heads are cut to create a stepped platform with a thinner top and thicker bottom, making it easier to mount the beam support on the column heads. The beam support is assembled by riveting the first and second modules together, making it easy to fit onto the column heads. The structure is stable. The first module has a mortise corresponding to the fixed tenon, ensuring a secure connection between the wooden beam and the column. Finally, the first steel sleeve is installed and glue is injected to complete the reinforcement of the dislocated wooden beams and columns. This reinforcement method is simple, practical, scientific, reasonable, and has good load-bearing capacity, providing technical support for the reinforcement treatment of this type of earthquake damage in the future.

[0016] 2. This invention ensures that the beam support and the wooden column are coaxial through ring cutting, which improves the stability of the reinforcement. By controlling the cutting thickness, the width of the misalignment is controlled, which ensures that the beam support is stably fitted at the end of the wooden column, preventing the beam support from slipping due to insufficient cutting thickness and the structural strength of the top of the wooden column from being reduced due to excessive cutting thickness.

[0017] 3. This invention controls the height of the beam support to be the same as the cutting height of the wooden column head, allowing the beam support to be completely fitted onto the wooden column head. By controlling the height of the fixing mortise to be the same as the height of the fixing tenon, and by making the lower part of the fixing mortise a solid structure, it provides support for the fixing tenon, thus enhancing the effect of tenon-to-tenon reinforcement of the wooden beam and wooden column. By controlling the diameter of the central hole of the beam support to be the same as the diameter of the cut wooden column head, it facilitates a stable connection between the beam support and the wooden column head. By controlling the ring width of the beam support, it ensures a stable connection between the fixing tenon and the beam support, further enhancing the effect of tenon-to-tenon reinforcement of the wooden beam and wooden column.
