Description

Technical Field

[0001] This invention belongs to the field of mortise and tenon construction, and particularly relates to a reinforced tenon structure for wooden buildings. Background Technology

[0002] The mortise and tenon joint, a structural feature of traditional Chinese architecture, utilizes wood and brick as primary building materials and a timber frame structure. Constructed from main components such as columns, beams, and purlins, these components are joined together using mortise and tenon joints to form a flexible framework. Although each individual component is relatively thin, the mortise and tenon joint allows the structure to withstand immense pressure. This structural principle relies not on the strength of individual components but on their interconnectedness and mutual support, making it a fundamental model for ancient Chinese architecture and furniture.

[0003] Many existing wooden buildings use relatively thin tenon joints. After prolonged use, these thin joints can crack under the weight they bear. To prevent cracks from causing breakage, steel plates are added for reinforcement to extend their lifespan. Therefore, designing a high-strength tenon is essential to prolong the lifespan of tenons in wooden buildings.

[0004] Traditional wooden building installations use wedges to reinforce mortise and tenon joints, making disassembly, repair, or reconstruction of wooden buildings difficult.

[0005] This invention designs a reinforced tenon structure for wooden buildings to solve the above problems. Summary of the Invention

[0006] To address the aforementioned deficiencies in the prior art, this invention discloses a reinforced tenon structure for wooden buildings, which is implemented using the following technical solution.

[0007] A reinforced mortise and tenon structure for wooden buildings includes a beam, columns, eaves purlins, L-shaped rods, threaded rods, and nuts. Two tenons on the lower sides of both ends of the beam correspond to mortises A on the upper ends of the two columns. The inclined surfaces B on the columns mate with the inclined surfaces A on the beam. The beam and the two columns are laterally tightened and fixed together by the threaded rods and nuts that pass through all three. Two horizontal eaves purlins, perpendicular to the beam, are fitted into the two mortises B on the upper sides of both ends without weakening the beam's load-bearing strength. The inclined surfaces D on the lower sides of the eaves purlins mate with the inclined surfaces C at the bottom of the corresponding mortise B. An L-shaped rod, mates with a nut on the threaded rod, slides within the L-shaped groove A connecting the mortise B and the lower end of the corresponding tenon. The inclined surface F at the lower end of the horizontal section of the L-shaped rod mates with the inclined surface E at the bottom of the slot C on the side wall of the corresponding eaves purlin. The upper oval hole of the vertical section of the L-shaped rod mates with the threaded rod. Structures are installed on the lower sides of both ends of the beam to cover the exposed ends of the threaded rods and the nuts.

[0008] As a further improvement to this technology, the rod hole on the beam for passing through the screw is connected to two inclined planes A, and the oval hole on the column that cooperates with the screw passes through the inclined plane B, ensuring an effective clearance between the column and the beam.

[0009] As a further improvement to this technology, the width of the vertical section of the slide groove A is greater than the length of its horizontal section, ensuring that the L rod can be vertically inserted into the slot A from bottom to top for flexible assembly and disassembly.

[0010] As a further improvement to this technology, the column has a slot B that mates with the vertical section of the L-bar, ensuring that the L-bar is fully engaged with the slot C on the corresponding eaves purlin to form a positioning.

[0011] As a further improvement to this technology, both ends of the beam have slots A on their lower sides that mate with the auxiliary block. The sidewall of slot A has a trapezoidal guide groove that mates with the trapezoidal guide block on the auxiliary block. A top rod that mates with the beam slides vertically in the groove B at the upper end of the auxiliary block. A wedge-shaped top block that mates with the top rod slides horizontally in the groove C on the sidewall of the auxiliary block that communicates with the groove B. A bolt that rotatably mates with the top block is screwed into the threaded hole on the sidewall of the auxiliary block. The auxiliary block has two shielding eaves that shield the exposed ends of the screw and the bolt from below.

[0012] As a further improvement to this technology, the inner wall of the tenon B is vertically flush with the upper end of the corresponding inclined surface A, ensuring that the tenon B does not weaken the load-bearing strength of the portion of the beam located between the two inclined surfaces A.

[0013] Compared to traditional mortise and tenon structures, the mortise and tenon joints of this invention are thinner but not load-bearing. The load-bearing parts in this invention are the inclined surface A on the beam and the inclined surface B on the column. This ensures that there is sufficient load-bearing area between the beam and the column, while also ensuring that the cross-section of the load-bearing part of the beam has a large height, thereby improving the load-bearing strength of the mortise and tenon structure. There is no need to add steel plates to reinforce the mortise and tenon joints, effectively extending the service life of the mortise and tenon structure.

[0014] In this invention, the mortise and tenon joints do not require the insertion of wedge blocks for pre-tightening reinforcement. Instead, the two columns at both ends of the porch beam are pulled toward the two inclined surfaces A of the porch beam by a horizontal screw, so that the porch beam and the two columns are subjected to force. Through the same screw, the inclined surface F on the L rod interacts with the inclined surface E at the bottom of the slot C of the eaves purlin. This results in a tight connection between the mortise groove A on the column and the tenon on the porch beam, as well as between the mortise groove B on the eaves purlin and the mortise groove on the porch beam, under the pull of the screw. The connection automatically loosens after the screw is removed, improving the installation and disassembly efficiency of the porch beam, eaves purlin, and columns.

[0015] This invention has a simple structure and good performance. Attached Figure Description

[0027] The accompanying drawings are schematic diagrams illustrating embodiments of the present invention to facilitate understanding of the structural operating principle. Specific product structures and dimensions can be determined based on the usage environment and conventional technologies.

[0028] like Figure 2 , 3 As shown in Figure 4, it includes a beam 1, a column 12, an eaves purlin 17, an L-shaped rod 20, a threaded rod 22, and a nut 23, among which... Figure 5 , 6As shown in Figure 8, the two tenons 2 on the lower sides of both ends of the beam 1 respectively correspond to the tenons A15 on the upper ends of the two columns 12; as shown in Figure 8. Figure 2 , 3 As shown, the inclined surface B13 on column 12 mates with the inclined surface A6 on beam 1, and beam 1 and the two columns 12 are laterally tightened and fixed together by the engagement of bolt 22 and nut 23 that pass through the three; as shown Figure 3 , 6 As shown in Figure 7, two mortise grooves B8 on the upper sides of both ends of the lintel 1, which do not weaken the load-bearing strength of the lintel 1, are respectively fitted with horizontal eaves purlins 17 perpendicular to it; as shown in Figure 7. Figure 4 , 6 As shown in Figure 10, the inclined surface D18 on the lower side of the eaves purlin 17 mates with the inclined surface C9 at the bottom of the corresponding tenon B8; as shown in Figure 10. Figure 4 , 6 As shown in Figure 7, an L-shaped rod 20, which mates with the nut 23 on the screw 22, slides within the L-shaped groove A3 at the lower end of the corresponding tenon 2, connecting the mortise B8 and the tenon 2. Figure 4 , 10 As shown, the inclined surface F5 on the lower side of the horizontal section end of L-rod 20 mates with the inclined surface E4 at the bottom of the corresponding side wall slot C19 of the eaves purlin 17, and the upper waist-shaped hole 14 of the vertical section of L-rod 20 mates with the screw 22; as shown Figure 3 , 4 As shown, both ends of the beam 1 are equipped with structures that cover the exposed ends of the screw 22 and the nut 23.

[0029] like Figure 4 , 6 As shown in Figure 8, the rod hole 7 on the beam 1, which is used to pass through the screw 22, is connected to the two inclined surfaces A6. The oval hole 14 on the column 12, which cooperates with the screw 22, passes through the inclined surface B13, ensuring that there is an effective clearance between the column 12 and the beam 1.

[0030] like Figure 4 , 7 As shown, the width of the vertical section of the slide groove A3 is greater than the length of its horizontal section, ensuring that the L rod 20 can be vertically inserted into the slot A10 from bottom to top for flexible assembly and disassembly.

[0031] like Figure 4 , 8 As shown, the column 12 has a slot B16 that mates with the vertical section of the L rod 20, ensuring that the L rod 20 is fully engaged with the slot C19 on the corresponding eaves purlin 17 to form a positioning.

[0032] like Figure 4 , 7As shown in Figure 9, both ends of the beam 1 have slots A10 on their lower sides that cooperate with the auxiliary block 24. The side wall of slot A10 has a trapezoidal guide groove 11 that cooperates with the trapezoidal guide block 25 on the auxiliary block 24. A top rod 30 that cooperates with the beam 1 slides vertically in the sliding groove B26 at the upper end of the auxiliary block 24. A wedge-shaped top block 31 that cooperates with the top rod 30 slides horizontally in the sliding groove C27 on the side wall of the auxiliary block 24 that communicates with the sliding groove B26. A bolt 32 that rotatably cooperates with the top block 31 is screwed into the threaded hole 28 on the side wall of the auxiliary block 24. The auxiliary block 24 has two shielding eaves 29 that shield the exposed ends of the screw 22 and the bolt 32 from the bottom.

[0033] like Figure 3 , 4 As shown in Figures 7 and 8, the inner wall of the tenon B8 is vertically flush with the upper end of the corresponding inclined surface A6, ensuring that the tenon B8 does not weaken the load-bearing strength of the portion of the beam 1 located between the two inclined surfaces A6.

[0034] The installation process of this invention is as follows: The tenons 2 on the lower sides of both ends of the beam 1 are inserted into the tenon grooves A15 at the upper ends of the two columns 12. The eaves purlins 17 are inserted into the two tenon grooves B8 of the beam 1. The inclined surface D18 of the eaves purlins 17 abuts against the inclined surface C9 of the corresponding tenon groove B8 and slides down to the inner wall of the tenon groove B8 under its own weight.

[0035] Then, vertically insert L rods 20 into the two grooves A3 of the beam 1, insert the horizontal section of L rods 20 into the horizontal section of the groove A3, and insert them into the slots C19 on the corresponding eaves purlin 17.

[0036] Next, insert the screw 22 horizontally into the rod hole 7 on the beam 1 and into the oval holes 14 on the two columns 12 and the two L rods 20.

[0037] Nuts 23 are screwed onto both ends of screw 22. The two nuts 23 press the corresponding L rods 20 into the slots B16 on the column 12 and make the horizontal section of L rod 20 further penetrate into the slot C19 on the eaves purlin 17. The inclined surface F5 on the horizontal section of L rod 20 interacts with the inclined surface E4 inside the slot C19, so that the eaves purlin 17 is tightly pressed against the inner wall of the tenon B8 and the inclined surface C9, and a gap is created with the outer wall of the tenon B8, which facilitates the quick removal of the eaves purlin 17 from the beam 1 after screw 22 is removed.

[0038] At the same time, as the two nuts 23 at both ends of the screw 22 are tightened, the inclined surfaces B13 on the two columns 12 are in close contact with the corresponding inclined surfaces A6 on the beam 1, causing the two columns 12 to move slightly relative to the beam 1 along the inclined surfaces A6. This creates a certain installation gap between the tenon grooves A15 on the two columns 12 and the side walls of the corresponding tenons 2 on the beam 1, facilitating the quick removal of the beam 1 from the two columns 12 after the screw 22 is removed.

[0039] Then, the two auxiliary blocks 24 are inserted vertically upward into the two slots A10 on the beam 1 and pushed horizontally into the trapezoidal guide groove 11 on the side wall of the slot A10, so that the shielding eaves 29 on the auxiliary blocks 24 effectively shield the exposed end of the screw 22 and the nut 23, achieving an aesthetic effect.

[0040] Next, rotate the bolts 32 on each auxiliary block 24. The bolts 32 cause the top block 31 to slide, and the top block 31 causes the top rod 30 to abut against the purlin 1 and effectively lock the position of the auxiliary block 24. Then, install the hanging ornaments 33 between the two sides of each column 12 and the eaves purlin 17. At this point, the installation of the present invention is completed.

[0041] After installation, because the inner wall of the tenon B8 where the eaves purlin 17 is located is vertically flush with the upper end of the corresponding inclined surface A6, the presence of the tenon B8 does not compromise the strength of the load-bearing portion of the upper inclined surface A6 of the canopy beam 1. This results in a larger cross-sectional area for the load-bearing portions of the canopy beam 1 and the column 12, thus ensuring the load-bearing strength of the canopy beam 1 without the need for additional reinforcing steel plates. This avoids the situation described above. Figure 1 The example shown illustrates how insufficient strength in the mortise and tenon joints of traditional wooden buildings leads to cracking at these joints.

[0042] The disassembly process of this invention is as follows: When it is necessary to disassemble this invention, first rotate the bolts 32 on each auxiliary block 24. The bolts 32 drive the top rod 30 to disengage from the beam 1 and release its locking state through a series of transmissions. Move the auxiliary block 24 horizontally out of the trapezoidal guide groove 11 and remove it through the slot A10.

[0043] Then, unscrew the nuts 23 at both ends of the screw 22, move the two L rods 20 horizontally out of the slot C19 and the corresponding horizontal section of the slide A3 on the eaves purlin 17, and remove them through the vertical section of the slide A3.

[0044] After the nuts 23 on the bolts 22 are unscrewed from the eaves purlin 17 and the column 12, gaps exist between the tenon 2 on the beam 1 and the mortise A15 on the column 12, and between the eaves purlin 17 and the corresponding mortise B8 on the beam 1. Therefore, the eaves purlin 17 can be easily removed from the beam 1, and the beam 1 can be easily removed from the column 12. This improves the disassembly efficiency of wooden buildings with mortise and tenon joints.

[0045] In summary, the beneficial effects of this invention are as follows: Although the mortise and tenon joint of this invention is relatively thin, it is not used as a load-bearing part. The load-bearing parts in this invention are the inclined surface A6 on the beam 1 and the inclined surface B13 on the column 12. This ensures that there is sufficient load-bearing area between the beam 1 and the column 12, while ensuring that the cross-section of the load-bearing part of the beam 1 has a large height, thereby improving the load-bearing strength of the mortise and tenon structure. There is no need to add steel plates to reinforce the mortise and tenon joint, effectively extending the service life of the mortise and tenon structure.

[0046] In this invention, the mortise and tenon joints do not require the insertion of wedge blocks for pre-tightening reinforcement. Instead, the two columns 12 at both ends of the beam 1 are pulled toward the two inclined surfaces A6 of the beam 1 by the transverse screw 22, so that the beam 1 and the two columns are subjected to force. Through the same screw 22, the inclined surface F5 on the L rod 20 interacts with the inclined surface E4 at the bottom of the slot C19 of the eaves purlin 17. This results in a tight connection between the mortise groove A15 on the column 12 and the tenon 2 on the beam 1, and between the eaves purlin 17 and the mortise groove B8 on the beam 1, under the pull of the screw 22. The connection automatically loosens after the screw 22 is removed, thus improving the installation and disassembly efficiency of the beam 1, the eaves purlin 17 and the columns 12.
