Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a device for reinforcing wooden beam-column joints. Background Technology
[0002] Timber structures are widely used around the world, ranging from single-family homes to multi-story apartment buildings. They are also used in low-rise commercial and public buildings such as restaurants, schools, churches, shops, and office buildings. Compared to reinforced concrete and masonry structures, timber-framed houses offer advantages such as longer lifespan, easier construction, shorter construction time, customizable interior design, better insulation, better ventilation, and earthquake resistance. Although the cost of timber is higher than that of concrete and masonry structures, the overall cost is not significantly higher due to the smaller number of construction workers, shorter construction period, lower labor costs, and lower finishing expenses.
[0003] Due to these characteristics, timber-framed buildings have been widely adopted in Asian countries such as Japan and South Korea. As is well known, timber-framed construction mostly employs traditional mortise and tenon joints. While mortise and tenon joints have many advantages, from a modern industrial perspective, they also have several drawbacks. First, most mortise and tenon joints are difficult to form using automated machinery, making mechanized production challenging. Second, most mortise and tenon joint fabrication requires skilled timber craftsmen, and such skilled workers are now scarce in my country, increasing construction costs. Third, the rigidity of mortise and tenon joints is relatively low; due to the loss of timber cross-sections, the mechanical properties at the joints decrease, making it difficult to support large timber structures. Fourth, current timber structures still have significant deficiencies in beam-column connections, limiting their use to low-rise timber-framed buildings; high-rise timber-framed buildings remain difficult to construct.

[0016] The beneficial effects of this invention are as follows: Compared with existing mortise and tenon joint reinforcement technology, this patented invention utilizes steel connectors to reinforce the wooden beam-column joint (column) and effectively transfer the load of the wooden beam, thereby improving the bending stiffness of the mortise and tenon joint and effectively transferring the upper load. This significantly improves the seismic performance and deformation capacity of the mortise and tenon joint wooden frame, meeting subsequent use requirements. In particular, the wooden beam-column joint reinforcement method of this patented invention has a simple structure, the components are easy to mechanize, the component installation is convenient, and the construction speed is fast and the cost is low. The fixed sleeves cause minimal damage to the columns, requiring only drilling through holes for quick installation. The fixed sleeves act as a transition point to secure the support frame. Simultaneously, clamping units are installed on different crossbeams, allowing adjustment of the pressure plate position to ensure stable clamping of the crossbeams. The support frame and the bottom of the clamping plates are connected by adjustable claws for stable holding, eliminating the need for external screws or bolts. This design facilitates easy installation and removal of the crossbeams. The top of the clamping plates and the fixed cylinder are secured by shock-absorbing units, effectively resisting instability. The fixed cylinder acts as a platform, forming a stable triangular structure on the upper and lower sides of the crossbeams through adjustable claws and shock-absorbing units. This results in overall stable stress distribution and high reliability, providing a new approach to fixing multiple crossbeams and columns with significant economic benefits.

Detailed Implementation
[0042] like Figure 1-7In this invention, a wooden beam-column joint reinforcement device includes a fixing cylinder 3 installed on a column 1. A support frame 5 is installed on one side of the fixing cylinder 3. The support frame 5 is provided with a top plate 501, which is supported on the bottom of a support beam unit 2. The column 1 includes a first slot 101, a fourth slot 104, a third slot 103, and a second slot 102 arranged along the axial direction. The support beam unit 2 includes a first crossbeam 201, a fourth crossbeam 204, a third crossbeam 203, and a second crossbeam 202 arranged along the axial direction. The first crossbeam 201 passes through the first slot 101, the second crossbeam 202 is inserted into the second slot 102, and the third crossbeam 203 and the fourth crossbeam 204 overlap in the third slot 103 and the fourth slot 104, respectively. Wooden beams and columns are commonly used supporting components in ancient buildings. As the main body bearing the load, they need to ensure their own strength. Since four horizontal beams need to be installed circumferentially along the column 1 during installation, the opening size of the column 1 is limited. Only the first slot 101 is a through slot. Therefore, only the insertion depth of the first horizontal beam 201 can relatively ensure its structural stability. The second horizontal beam 202, the third horizontal beam 203, and the fourth horizontal beam 204 do not meet the above conditions. The fixing cylinder 3 serves as a transition and reinforcement to avoid the first slot 101, the second slot 102, the third slot 103, and the fourth slot 104. It can maintain the strength of the column 1 and avoid stress concentration at the slot. At the same time, it serves as a transition point to complete the installation of the support frame 5, supporting multiple horizontal beams from the bottom and transmitting the force to ensure the overall force balance.
[0043] In the preferred embodiment, the fixing cylinder 3 includes two opposing semi-circular plates 301. Ear plates 302 are provided on both sides of each semi-circular plate 301. A notch 303 is provided on each semi-circular plate 301, with the height of the notch 303 being the same as the height of the supporting beam unit 2. Multiple through holes 105 are provided through the column 1, and bolts 4 are inserted into these holes 105. The semi-circular plates 301 are connected to the column 1 via the bolts 4. The inner diameter of the semi-circular plates 301 matches the outer diameter of the column 1. The notch 303 provides an installation channel for the supporting beam unit 2, ensuring convenient installation. This embodiment only provides through holes 105 on the column 1, without damaging other parts of the column 1 and supporting beam unit 2, thus maximizing the stability of the overall structure supported by the wooden beam column.
[0044] like Figure 8-14In the preferred embodiment, multiple clamping units 6 are fitted onto the support beam unit 2. Each clamping unit 6 includes two opposing clamping plates 601 connected by bolts 4. The bottom of the top plate 501 is connected to the fixing cylinder 3 via multiple triangular ribs 502. Adjustable claws 7 are hinged to the triangular ribs 502, and hooks 704 are provided on the adjustable claws 7. The hooks 704 are connected to the clamping plates 601 by bolts 4. The clamping units 6 are easy to install and remove, causing minimal damage to the crossbeam unit 2 and preventing the transmission of the corrosion characteristics of the bolts or screws to the crossbeam, thus not affecting the interior of the crossbeam. The hooks 704 of the adjustable claws 7 support the crossbeam from below. Through this simple design, the effective range of the lifting frame 5 is expanded and extended, and the operation is convenient.
[0045] In a preferred embodiment, a rotating rod 603 is provided on one side of the clamping plate 601, and a pressure plate 602 is threaded onto the rotating rod 603. The pressure plate 602 is provided with multiple protrusions 604, which press against the outer wall of the support beam unit 2. The position of the pressure plate 602 can be adjusted according to the operation process. When the clamping plate 601 is not completely fixed, the pressure plate 602 can be retracted to hide the protrusions 604. When the designed position is reached, the pressure plate 602 extends outward and weds the protrusions 604 into the crossbeam. Preferably, in order to improve the overall restraint effect, the protrusions 604 are inclined towards the column 1, and the height of the protrusions 604 is set in the range of 3-5mm, which can ensure the overall fixation is firm while avoiding damage to the crossbeam structure.
[0046] In the preferred embodiment, a first mounting sleeve 605 is provided on the outer side of the clamping plate 601, and a second mounting sleeve 606 is provided on the outer side of the pressure plate 602. The second mounting sleeve 606 passes through the first mounting sleeve 605. A frustum 610 is provided on the rotating rod 603, and the frustum 610 presses against the first mounting sleeve 605. A cover plate 612 is threaded to the outer side of the first mounting sleeve 605, and the rotating rod 603 passes through the cover plate 612. A hexagonal head 609 is provided at the end of the rotating rod 603. The outer diameter of the second mounting sleeve 606 is equal to the inner diameter of the first mounting sleeve 605. At the same time, the outer diameter of the rotating rod 603 is equal to the inner diameter of the second mounting sleeve 606. The outer diameter of the frustum 610 is smaller than the outer diameter of the first mounting sleeve 605 but larger than the inner diameter of the first mounting sleeve 605. By restricting the rotation of the rotating rod 603, it can only rotate around its own axis, thus converting the circular motion into the linear motion of the pressure plate 602. The hexagonal head 609 facilitates the transmission of torque by the operator.
[0047] In the preferred embodiment, the inner side of the clamping plate 601 is provided with multiple grooves 607, the pressure plate 602 is provided with multiple vertical plates 608, protrusions 604 are provided on the vertical plates 608, and the frustum 610 is provided with a first ring 611, which is inserted into the first mounting sleeve 605. The vertical plates 608 and the grooves 607 cooperate with each other to reduce the impact on the structure of the clamping plate 601 itself and ensure the stability of the load-bearing capacity. At the same time, the protrusions 604 penetrate the crossbeam to the maximum extent at different positions, resulting in a better overall fixing effect. The first ring 611 further improves the rotation accuracy of the rotating rod 603, and the overall motion response is faster.
[0048] In the preferred embodiment, the triangular rib plate 502 is provided with mounting holes 503. The adjusting claw 7 includes a base 701, and a pin 706 passes through the mounting holes 503 and the base 701 respectively. A rotating sleeve 702 is rotatably provided on one side of the base 701. The rotating sleeve 702 is threadedly connected to a threaded post 703, and a hook 704 is fixed to the end of the threaded post 703. The triangular rib plate 502 enhances the load-bearing capacity and provides clearance, facilitating the installation of the base 701, reducing space occupation, and allowing the base 701 to be hidden, resulting in better overall aesthetics. By rotating the rotating sleeve 702, the position of the hook 704 can be adjusted until it pulls the bolt 4 on the clamping plate 601. The overall constraint effect is stable. Since the hook 704 is in a reverse-pull state, the upper side of the hook 704 is simultaneously constrained by the bolt 4 located on the upper side, thus restricting the overall degree of freedom, resulting in good fixing effect and easier installation and removal, without the cumbersome process of fixing with bolts or screws for transmission.
[0049] In the preferred embodiment, the hook 704 is provided with a clearance groove 705, the rotating sleeve 702 has a cavity with a first through hole 707 passing through it, the base 701 has a second through hole 708 passing through it, the bolt 4 passes through the second through hole 708 and the first through hole 707, and the base 701 is also provided with a second ring 709, in which the rotating sleeve 702 is inserted. The rotating sleeve 702 can rotate better along the axis of the first through hole 707 through the second ring 709, resulting in good overall force transmission. The bolt 4 fully constrains the rotating sleeve 702, thereby ensuring the stability of the structure.
[0050] like Figure 15-23In the preferred embodiment, multiple jacket units 6 are connected by a balancing unit 9. The balancing unit 9 includes a mounting base 901, which is installed on the jacket units 6 by bolts 4. A tie plate 902 is supported on the mounting base 901, and a damping unit 8 is provided on the tie plate 902. The damping unit 8 includes a support 803, and a spring 801 is fixed on the support 803. A fixing cable 802 is provided at the end of the spring 801, and the fixing cable 802 is fixedly connected to the fixing cylinder 3. The tie plate 902 connects the four crossbeams using the mounting base 901, ensuring mutual restraint, even force distribution, and mutual cooperation to ensure the structural stability of the wooden beams and columns, while also improving the individual condition of each beam. The fixing cable 802 can be easily installed on the fixing cylinder 3 to hold the crossbeams from above. The spring 801 can play a buffering role, avoiding the defect of local breakage caused by ineffective stress release.
[0051] In the preferred embodiment, the fixed cylinder 3 is provided with multiple locking rings 304 on its exterior, and the fixing cable 802 passes through the locking rings 304. The mounting base 901 is provided with two side plates 904 parallel to each other at its bottom. The bolt 4 passes through the clamping plate 601 and the side plates 904. The mounting base 901 is provided with a screw 905, which is connected to the tie plate 902 by a nut 910. The screw 905 is provided with a detachable washer 903. The tie plate 902 is provided with staggered steps 906 on both sides. The steps 906 are provided with oval grooves 907. The tie plate 902 is provided with a countersunk hole 908 in the middle, and a third through hole 909 passes through the countersunk hole 908. The support 803 is provided with a round rod 804 at its bottom, and a threaded hole 805 is provided on the round rod 804. The screw 806 passes through the third through hole 909 and the threaded hole 805. The direction of the fixing cable 802 can be changed by rotating the support 803, making installation more convenient. The pad 903 can ensure better fixation of the tie plates 902 on both sides, and the overall force transmission is stable. At the same time, the oval groove 907 ensures high installation efficiency while having a certain buffer margin. During use, a compression spring is set in the oval groove 907 to cope with lateral displacement, which can reduce the generation of excessive displacement and improve the overall self-restraint effect.
