Description

Technical Field

[0001] This invention relates to the field of self-built house reinforcement construction technology, and in particular to a prefabricated bamboo structure construction method for self-built house reinforcement. Background Technology

[0002] Traditional self-built houses generally use masonry structures, mostly two to one story, with simple layouts and identical room configurations on both floors, often featuring a central living room flanked by bedrooms. To save costs, many of these houses use hollow brick walls as load-bearing structures, resulting in poor overall building integrity. Over time, these houses gradually reveal quality problems such as localized wall cracks and uneven foundation settlement, with most being rated as C or D safety levels, posing serious safety hazards. Traditional reinforcement solutions mainly fall into two categories: demolishing part of the walls and replacing them with a cast-in-place frame structure or adding vertical steel structural supports. Traditional reinforcement solutions have the following problems: 1. Traditional reinforcement processes require a long curing time for concrete to develop sufficient strength, resulting in a long construction cycle.

[0003] 2. Reinforcement often requires secondary renovation, which further increases time and money costs. Moreover, secondary renovation will obscure the reinforced structure, and if deformation or cracking occurs in the reinforced structure, it will not be detected in time, which will lead to people not being able to evacuate in time in the event of a collapse.

[0004] 3. In traditional construction techniques, the construction of frame columns involves chiseling away the wall at the corner of the masonry wall, rearranging the steel bars, and pouring concrete. Although the overall structure is relatively intact after completion, the construction process damages the mutual connection between the four walls, which poses a significant risk.

[0005] 4. In traditional construction methods, the construction of a frame structure requires the removal of the masonry walls under the precast slabs, the re-laying of steel bars, and the pouring of concrete. This method requires scaffolding to be installed throughout the house, and all furniture and items inside the house must be completely removed.

[0006] 5. The option of adding vertical steel structure supports in certain areas can effectively solve the problem of insufficient vertical structural support, but it is difficult to form an overall frame structure. Summary of the Invention

[0007] This invention aims to solve the technical problems existing in the prior art. Therefore, this invention proposes a prefabricated bamboo structure construction method for reinforcing self-built houses.

[0008] A construction method for a prefabricated bamboo structure for reinforcing self-built houses according to an embodiment of the present invention includes the following steps: S1. A formwork support frame is erected against the wall at the midpoint of the shortest side of the geometric dimensions of each room on the first floor to support the first precast slab against the wall. S2. Excavate foundation pits around each room on the first floor, lay waterproof membrane, pre-embed support components in the foundation pits, and then pour concrete, with the upper end of the support components protruding from the foundation pits. S3. Square openings are drilled around the ceiling of each room on the first floor for the first bamboo pillar to pass through. The upper end of the first bamboo pillar extends into the second floor through the openings, and the lower end of the first bamboo pillar is connected to the support. S4. The upper end of the first bamboo column is connected to the first connector, the second connector and the third connector respectively; S5. The end of the first long bamboo beam is connected to the first bamboo column through the first connector. The first long bamboo beam is arranged below the roof slab on the first floor along the longest side of the room's geometric dimensions. S6. Remove the formwork support frame. The end of the first short bamboo beam is connected to the upper end of the first bamboo column through the second connector. The first short bamboo beam is arranged below the roof slab on the first floor along the shortest side of the room's geometric dimensions. S7. Install second bamboo pillars around each room on the second floor. The upper end of the second bamboo pillar is connected to the fourth connector, and the lower end of the second bamboo pillar is connected to the third connector. S8. The end of the second long bamboo beam is connected to the second bamboo column through the fourth connector. The second long bamboo beam is arranged below the second floor ceiling along the longest side of the room's geometric dimensions. The end of the second short bamboo beam is connected to the second bamboo column through the fourth connector. The second short bamboo beam is arranged below the second floor ceiling along the shortest side of the room's geometric dimensions.

[0009] A prefabricated bamboo structure construction method for reinforcing self-built houses according to an embodiment of the present invention has at least the following beneficial effects: The first bamboo column, second bamboo column, first long bamboo beam, first short bamboo beam, second long bamboo beam, and second short bamboo beam in this application are all bamboo structures. Bamboo structures possess lightweight and high-strength mechanical properties, making them suitable for assembly work in existing buildings within confined spaces. Without damaging the original walls, the original masonry structure composed of precast slabs and hollow brick walls is transformed into a lightweight, reliable, and earthquake-resistant prefabricated bamboo frame structure. Furthermore, this structural system conforms to the characteristics of self-built houses, allowing for the erection of a frame structure in each small room, forming multiple frame systems that share the load, and can even be extended to all types of masonry structure houses.

[0010] Because the layout of the self-built houses is similar across floors, each small room uses a frame structure, forming multiple frame systems that share the load. This lightweight frame not only meets the characteristics of self-built houses but also effectively distributes the load of the original walls, significantly improving the overall structure's integrity, load-bearing capacity, and earthquake resistance.

[0011] All bamboo structures and related connecting components can be prefabricated in the factory and quickly assembled on-site, resulting in a very short construction period and minimizing disruption to residents' daily lives. Compared to traditional reinforcement solutions, this method saves significant labor and time costs.

[0012] Since the on-site conditions are often quite complex, further processing is often required on-site. Furthermore, bamboo grooving, drilling, and cutting can all be completed on-site, which is relatively simple and requires less technical expertise from on-site equipment and personnel.

[0013] Bamboo is less expensive than steel or reinforced concrete structures, and its natural texture and color are beautiful and elegant, creating a distinctive interior effect. It can eliminate the need for secondary renovations, significantly lowering the economic threshold for renovation, shortening the construction period, and avoiding the health effects of formaldehyde emitted from building materials.

[0014] Bamboo beams and pillars no longer require decoration, and the deformation status of each component can be viewed intuitively in real time. If deformation occurs, it can be detected in time.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Please see Figure 1 A prefabricated bamboo structure construction method for reinforcing self-built houses according to an embodiment of the present invention includes the following steps: S1. A formwork support 940 is erected against the wall at the midpoint of the shortest side of each room's geometric dimensions on the first floor to support the first precast slab 930 against the wall. (See reference...) Figure 4 and Figure 5 Only a disc-lock formwork scaffold 940 is erected against the wall at the midpoint of the shortest side of the room's geometry. The scaffold 940 is two steps long and one step wide, and does not need to be erected throughout the entire room; it is not required on the second floor. The scaffold 940 is mainly used to support the precast slabs 930 through the square opening made in step S5. Only the furniture placed against the wall and in the area where the scaffold 940 is erected needs to be moved to the center of the room; it does not need to be moved out of the room, and the second floor can be habitable normally.

[0033] S2. Excavate foundation pits around each room on the first floor and lay waterproof membrane. After pre-embedding support components in the foundation pits, pour concrete, with the upper ends of the support components protruding from the foundation pits. The support components include galvanized square tubes 100, and three galvanized square tubes 100 are arranged in a triangular pattern.

[0034] S21. A 2-3cm long steel bar segment protrudes from the lower part of the galvanized square tube 100. The galvanized square tube 100 is tied to the copper tube 110 with the steel bar segment and placed together in the foundation pit. The upper end of the galvanized square tube 100 and both ends of the copper tube protrude from the foundation pit. Short steel bars of 2-3cm are welded around the galvanized square tube 100, which can be easily tied to the copper tube 110. (See reference...) Figure 1 , Figure 2 and Figure 3 The galvanized surface of the square tube provides excellent corrosion resistance.

[0035] S22. UHPC high-strength concrete is poured into the foundation pit to form the foundation 950. After the concrete is poured, hot water is injected into the copper pipe 110 for curing. Hot water at 50℃ is injected into the copper pipe 110 for curing to accelerate the concrete solidification and increase the concrete strength. The curing time is 3 days, with continuous heating for 3 days to make its strength reach 70% of the predetermined value, resulting in high curing efficiency.

[0036] S23. Inject cement grout into the copper pipe 110 to improve its strength, and pour self-compacting concrete into the galvanized square pipe 100. The aggregate diameter is small, and vibration is not required, which improves the strength of the square pipe.

[0037] S3. Square openings 931 are chiseled around the perimeter of the ceiling slabs of each room on the first floor to allow the first bamboo pillar 210 to pass through. The upper end of the first bamboo pillar 210 extends into the second-floor slab through the openings, and the lower end of the first bamboo pillar 210 is connected to the galvanized square tube 100. A square opening 931 slightly larger than the side length of the pillar is chiseled around the perimeter of the ceiling slabs of each room on the first floor. The self-built house uses masonry walls 910 as the supporting structure, with ground beams 920 below the masonry walls 910. The traditional construction method involves chiseling out areas at the four corners of the masonry walls 910 to pour frame columns, which damages the structural integrity and load-bearing capacity, and breaks the interlocking between the four walls, posing a significant risk and making wall collapse highly likely. Compared with the traditional solution, the embodiment of this application does not require damage to the walls and does not compromise the original wall's load-bearing capacity and integrity.

[0038] Self-built houses often use precast slabs 930 spliced ​​together as floor slabs. The width of the precast slabs 930 is about 50cm or 60cm. They are overlapped on the masonry walls 910 and placed parallel to the short side of the geometric plane. If the traditional construction method is followed, the lower part of the wall of the precast slabs 930 needs to be chiseled out to pour frame beams. All the precast slabs 930 will have no support points at the bottom, and formwork 940 must be erected throughout the house. In the embodiment of this application, only a small hole needs to be chiseled in the two precast slabs 930 on both sides of the shortest side of the geometric plane of the house. The affected area is small, the area of ​​formwork 940 that needs to be erected is small, the wall is not affected, and the rest of the precast slabs 930 are not affected.

[0039] S4. The upper end of the first bamboo pillar 210 is successively connected to the first connector 400, the second connector 500, and the third connector 600. (See reference) Figure 1 and Figure 6 First, insert the first plug plate 410 into the first cross groove 211 of the first bamboo column 210 along the first floor roof. Then, insert the second plug plate 510 into the first cross groove 211 of the first bamboo column 210 along the first floor roof in the vertical direction of the first plug plate 410. Next, on the second floor, insert the lower end of the third connector 600 into the first cross groove 211 to fix the first connector 400 and the second connector 500, and embed the whole into the first bamboo column 210.

[0040] S5. The end of the first long bamboo beam 220 is connected to the first bamboo column 210 through the first connector 400. The first long bamboo beam 220 is arranged along the longest side of the room's geometric dimensions below the first-floor roof slab. At this time, the precast slabs 930 are all supported, and the safety hazards during construction are eliminated.

[0041] S6. Remove the formwork support 940. The end of the first short bamboo beam 230 is connected to the upper end of the first bamboo column 210 through the second connector 500. The first short bamboo beam 230 is arranged below the first floor ceiling along the shortest side of the room's geometric dimensions.

[0042] S7. Install second bamboo pillars 310 around each room on the second floor. The upper end of the second bamboo pillar 310 is connected to the fourth connector 700, and the lower end of the second bamboo pillar 310 is connected to the third connector 600. Remove the window of the middle room on the second floor, and use an electric hoist to hoist the bamboo pillars and bamboo beams to the second floor. There is no need to damage other structures of the house, and there is no need to install the formwork 940. The first floor can be used normally when the second-floor beams and pillars are installed. Only the furniture placed against the wall and in the area where the formwork 940 is erected needs to be moved to the center of the room. There is no need to move it out of the room. Apply lubricant to the top and bottom plate of the second bamboo pillar 310. Align the fourth cross groove 311 at the bottom of the second bamboo pillar 310 with the third connecting plate 630 on the upper part of the third connector 600 on the first floor and push it in. Then install the third T-shaped plate 622 on the other side to ensure that the top of the pillar can tightly support the roof of the second floor after installation.

[0043] S8. The end of the second long bamboo beam 320 is connected to the second bamboo column 310 through the fourth connector 700. The second long bamboo beam 320 is arranged below the second floor ceiling along the longest side of the room's geometric dimensions. The end of the second short bamboo beam 330 is connected to the second bamboo column 310 through the fourth connector 700. The second short bamboo beam 330 is arranged below the second floor ceiling along the shortest side of the room's geometric dimensions.

[0044] The first bamboo column 210, the second bamboo column 310, the first long bamboo beam 220, the first short bamboo beam 230, the second long bamboo beam 320, and the second short bamboo beam 330 in this application are all bamboo structures. Bamboo structures possess lightweight and high-strength mechanical properties, making them suitable for assembly work in existing buildings within confined spaces. Without damaging the original walls, the original masonry structure composed of precast panels 930 and hollow brick walls is transformed into a lightweight, reliable, and earthquake-resistant prefabricated bamboo frame structure. Furthermore, this structural system conforms to the characteristics of self-built houses, allowing for the erection of a frame structure in each small room, forming multiple frame systems that share the load, and can even be extended to all types of masonry structure houses.

[0045] Because the layout of the self-built houses is similar across floors, each small room uses a frame structure, forming multiple frame systems that share the load. This lightweight frame not only meets the characteristics of self-built houses but also effectively distributes the load of the original walls, significantly improving the overall structure's integrity, load-bearing capacity, and earthquake resistance.

[0046] All bamboo structures and related connecting components can be prefabricated in the factory and quickly assembled on-site, resulting in a very short construction period and minimizing disruption to residents' daily lives. Compared to traditional reinforcement solutions, this method saves significant labor and time costs.

[0047] Since the on-site conditions are often quite complex, further processing is often required on-site. Furthermore, bamboo grooving, drilling, and cutting can all be completed on-site, which is relatively simple and requires less technical expertise from on-site equipment and personnel.

[0048] Bamboo is less expensive than steel or reinforced concrete structures, and its natural texture and color are beautiful and elegant, creating a distinctive interior effect. It can eliminate the need for secondary renovations, significantly lowering the economic threshold for renovation, shortening the construction period, and avoiding the health effects of formaldehyde emitted from building materials.

[0049] Bamboo beams and pillars no longer require decoration, and the deformation status of each component can be viewed intuitively in real time. If deformation occurs, it can be detected in time.

[0050] In some embodiments, see Figure 1 , Figure 7 and Figure 8The first bamboo post 210 has a first cross groove 211 at its upper end, which is used to connect with the first connector 400, the second connector 500, and the third connector 600. The first bamboo post 210 has a slot 212 at its lower end, into which a galvanized steel pipe, narrower at the top and wider at the bottom, is embedded for subsequent connection with the galvanized steel pipe pre-embedded in the foundation 950. The first long bamboo beam 220 has a second cross groove 221 at its end, which is used to connect with the first connector 400. The first short bamboo beam 230 has a third cross groove 231 at its end, which is used to connect with the second connector 500. The second bamboo post 310 has a fourth cross groove 311 at its lower end, which is used to connect with the third connector 600. The second bamboo post 310 has a fifth cross groove 312 at its upper end, which is used to connect with the fourth connector 700. The end of the second long bamboo beam 320 is provided with a sixth cross groove 321, which is used to connect with the fourth connector 700. The end of the second short bamboo beam 330 is provided with a seventh cross groove 331, which is used to connect with the fourth connector 700.

[0051] The first bamboo pillar 210 was transported indoors. A first cross groove 211 was pre-cut into the top of the bamboo pillar 210 according to the design drawings. A galvanized steel pipe, narrower at the top and wider at the bottom, was embedded in the bottom slot 212 for later connection with the galvanized square tube 100 pre-embedded in the foundation 950. Self-compacting concrete was poured into the narrower upper part of the galvanized square tube 100, using small-diameter aggregate that eliminates the need for vibration, thus increasing the strength of the square tube. First, the upper part of the first bamboo pillar 210 was extended into the second-floor area through an opening in the roof slab. Then, the lower part was connected to the galvanized square tube 100. After installation, the top of the pillar was slightly higher than the second-floor area by 2cm.

[0052] In some embodiments, see Figure 1 , Figure 7 and Figure 8The first cross groove 211 includes a first groove segment 2111 and three second groove segments 2112 that are connected. The depth of the first groove segment 2111 is less than the depth of the second groove segments 2112. The first groove segment 2111 is arranged against the wall along the longest side of the room's geometric dimensions. The first connector 400 includes a first plug plate 410, a first partition plate 420, and two first connecting plates 430 that are connected. The first plug plate 410 is detachably connected to the two second groove segments 2112 of the first cross groove 211. The first partition plate 420 is connected between the first bamboo column 210 and the first long bamboo beam 220. The first partition plate 420 is provided with a first T-shaped groove 421. A first T-shaped plate 422 is inserted into the first T-shaped groove 421. The two first connecting plates 430 are connected to the first partition plate 420 and located on both sides of the first T-shaped plate 422. The first T-shaped plate 422 and the two first connecting plates 430 are detachably connected to the second cross groove 221. The first connecting plate 430 and the first T-shaped plate 422 are inserted into the second cross groove 221 to restrict the first long bamboo beam 220 from moving up, down, left, and right, thus ensuring the stability of the first long bamboo beam 220 in supporting the roof slab of the first floor.

[0053] See Figure 1 and Figure 9 The second connector 500 includes a second plug-in plate 510, a second partition plate 520, and two second connecting plates 530 connected to each other. The second plug-in plate 510 is detachably connected to the first groove segment 2111 and the second groove segment 2112 of the first cross groove 211. The first plug-in plate 410 is provided with a clearance groove 411 for the second plug-in plate 510 to pass through. The second plug-in plate 510 is provided with a first clearance notch 511. The portion of the second plug-in plate 510 corresponding to the first clearance notch 511 passes through the clearance groove 411 and extends into the first groove segment 2111. The bottom wall of the first groove segment 2111 supports the inner wall of the first clearance notch 511, ensuring that the first plug-in plate 410 and the second plug-in plate 510 can be smoothly inserted into the first cross groove 211.

[0054] The second partition 520 is connected between the first bamboo column 210 and the first short bamboo beam 230. The second partition 520 has a second T-shaped groove 521 for inserting the second T-shaped plate 522. Two second connecting plates 530 are connected to the second partition 520 and located on both sides of the second T-shaped plate 522. The second T-shaped plate 522 and the two second connecting plates 530 are detachably connected within the third cross groove 231. By inserting the second connecting plates 530 and the second T-shaped plate 522 into the third cross groove 231, the vertical and horizontal movement of the second short bamboo beam 330 is restricted, ensuring the stability of the second short bamboo beam 330's support for the first-floor roof slab.

[0055] In step S6, the first plug-in plate 410 is first inserted into the two second slots 2112 along the first floor roof slab. Then, the second plug-in plate 510 is inserted into the first cross slot 211 along the first floor roof slab in the vertical direction of the first plug-in plate 410, with the first clearance notch 511 correspondingly inserted into the first slot 2111. The first connector 400 is installed first, followed by the second connector 500, mainly because the first plug-in plate 410 is provided with a clearance slot 411. Inserting the first plug-in plate 410 first makes it easier for the second plug-in plate 510 to pass through the clearance slot 411 and extend into the first slot 2111. At the same time, the second plug-in plate 510 can also prevent the first plug-in plate 410 from coming out.

[0056] In some embodiments, see Figure 1 and Figure 10 The third connector 600 includes a cross-shaped protrusion 610, a third partition 620, and two third connecting plates 630 connected together. The cross-shaped protrusion 610 is detachably connected to the first cross groove 211. The cross-shaped protrusion 610 has a second clearance notch 612 corresponding to the first groove segment 2111. The cross-shaped protrusion 610 is cross-shaped and has four protruding segments. The four protruding segments protrude downward along the third partition 620, and their protruding lengths are arranged in a pattern of three long and one short. The cross-shaped protrusion 610 has an eighth cross groove 611, which is used for the first plug-in plate 410 and the second plug-in plate 510 to extend into. This can improve the connection strength between the first connector 400, the second connector 500, the third connector 600 and the first cross groove 211. The cross-shaped protrusion 610 can also limit the left and right swaying of the first plug-in plate 410 and the second plug-in plate 510. The third partition 620 is connected between the first bamboo column 210 and the second bamboo column 310. The third partition 620 has a third T-shaped groove 621 for inserting a third T-shaped plate 622. Two third connecting plates 630 are connected to the third partition 620 and located on either side of the third T-shaped plate 622. The third T-shaped plate 622 and the two third connecting plates 630 are detachably connected to a fourth cross groove 311. The insertion of the third connecting plates 630 and the third T-shaped plates 622 into the fourth cross groove 311 restricts the forward, backward, left, and right movement of the second bamboo column 310, ensuring the stability of the second bamboo column 310's support for the second-floor roof slab.

[0057] In some embodiments, see Figure 1 , Figure 9 and Figure 10 The first plug-in plate 410 is provided with a first inclined surface 412, which extends from the upper part of the end of the first plug-in plate 410 away from the first partition plate 420 to the middle of the side wall of the clearance groove 411. The second plug-in plate 510 is provided with a second inclined surface 512, which extends into the first groove section 2111. The distance between the second inclined surface 512 and the bottom of the second plug-in plate 510 gradually increases in the direction away from the second partition plate 520.

[0058] The eighth cross groove 611 is provided with a first wedge block 6111 and a second wedge block 6112. The eighth cross groove 611 has four interconnected groove segments. The second wedge block 6112 is located in the groove segment of the eighth cross groove 611 corresponding to the second clearance notch 612. The direction of the groove segment where the first wedge block 6111 is located is perpendicular to the direction of the groove segment where the second wedge block 6112 is located. The first wedge block 6111 abuts against the first inclined surface 412, and the second wedge block 6112 abuts against the second inclined surface 512. By the cooperation of the first wedge block 6111 and the first inclined surface 412, the first connecting member 400 is prevented from dislodging from the first cross groove 211. By the cooperation of the second wedge block 6112 and the second inclined surface 512, the second connecting member 500 is prevented from dislodging from the first cross groove 211.

[0059] In some embodiments, see Figure 1 and Figure 11 The fourth connector 700 includes a cross plate 710, a fourth partition plate 720, a fifth partition plate 740, two fourth connecting plates 730, and two fifth connecting plates 750. The cross plate 710 is inserted into the fifth cross groove 312 of the second bamboo post 310. The fourth partition plate 720 and the fifth partition plate 740 connect two perpendicular ends of the cross plate 710. The fourth partition plate 720 is located between the second bamboo post 310 and the second long bamboo beam 320. The fourth partition plate 720 is provided with a fourth T-shaped groove 721 for inserting a fourth T-shaped plate 722. The two fourth connecting plates 730 are connected to the fourth partition plate 720 and located on both sides of the fourth T-shaped plate 722. The fourth T-shaped plate 722 and the two fourth connecting plates 730 are detachably connected to the sixth cross groove 321. The fourth connecting plate 730 and the fourth T-shaped plate 722 are inserted into the sixth cross groove 321 to restrict the second long bamboo beam 320 from moving up, down, left, and right, thus ensuring the stability of the second long bamboo beam 320 in supporting the roof slab of the second floor.

[0060] The fifth partition 740 is located between the second bamboo column 310 and the second short bamboo beam 330. The fifth partition 740 has a fifth T-shaped groove 741 for inserting a fifth T-shaped plate 742. Two fifth connecting plates 750 are connected to the fifth partition 740 and located on either side of the fifth T-shaped plate 742. The fifth T-shaped plate 742 and the two fifth connecting plates 750 are detachably connected to the seventh cross groove 331. The insertion of the fifth connecting plates 750 and the fifth T-shaped plates 742 into the seventh cross groove 331 restricts the vertical and horizontal movement of the second short bamboo beam 330, ensuring the stability of the second short bamboo beam 330's support for the second-floor roof slab.

[0061] In some embodiments, see Figure 1 , Figure 8 and Figure 12The first long bamboo beam 220 is connected to the first connecting member 400 via a bolt assembly 800 and a first T-shaped plate 422. The end of the first long bamboo beam 220, on the wall-facing side, has a first connecting hole 222 communicating with the second cross groove 221. The end of the first long bamboo beam 220, on the side away from the wall, has a second connecting hole 223 communicating with the second cross groove 221. The first connecting hole 222 has a hexagonal cross-section, and the second connecting hole 223 has a circular cross-section. The bolt assembly 800 includes a first connecting sleeve 810, a connecting bolt 820, and a second connecting sleeve 830. The two ends of the connecting bolt 820 are respectively provided with a first external thread 821 and a second external thread 822. The first external thread 821 and the second external thread 822 have opposite directions of rotation. The middle of the connecting bolt 820 is smooth, and one end of the connecting bolt 820 is provided with a first internal hexagon countersunk hole 823. The first connecting sleeve 810 has a through-hole 811 that is adapted to connect with the first external thread 821. The first connecting sleeve 810 has a hexagonal cross-section and extends into the first connecting hole 222. The second connecting sleeve 830 has a second internal hexagon countersunk hole 831 at one end and a second threaded hole at the other end for adapting to connect with the second external thread 822. The second connecting sleeve 830 has a circular cross-section and connects into the second connecting hole 223.

[0062] In step S7, a first connecting sleeve 810 is inserted into the first connecting hole 222 of the first long bamboo beam 220, with the first connecting hole 222 of the first long bamboo beam 220 placed against the wall; the first long bamboo beam 220 is pushed upward along the wall to ensure that the second cross grooves 221 at both ends of the first long bamboo beam 220 can connect with the first connector 400, and that the first connecting hole 222 is aligned with the reserved bolt holes of the first connector 400 (the first connecting plate 430 has reserved bolt holes). The T-shaped plate 422 is inserted between the second cross groove 221 and the two first connecting plates 430; the connecting bolt 820 is inserted along the second connecting hole 223, with the first hexagonal countersunk hole 823 facing outwards. A hexagonal screwdriver is used to screw the connecting bolt 820 into the first connecting sleeve 810. The second connecting sleeve 830 abuts against the connecting bolt 820 along the second connecting hole 223, with the second hexagonal countersunk hole 831 facing outwards. A hexagonal screwdriver is used to screw the second connecting sleeve 830 into the second connecting hole 223. The cross-section of the first connecting hole 222 is hexagonal, which restricts the first connecting sleeve 810 from rotating, allowing the connecting bolt 820 to be tightly screwed into it. The cross-section of the second connecting hole 223 is circular, facilitating the rotation of the second connecting sleeve 830 by the hexagonal screwdriver, allowing the second connecting sleeve 830 to be tightly screwed into the first long bamboo beam 220.

[0063] The first short bamboo beam 230 has a first connecting hole 222 and a second connecting hole 223 at its end, and is connected to the second connecting member 500 via a bolt assembly 800. The lower end of the second bamboo column 310 has a first connecting hole 222 and a second connecting hole 223, and is connected to the third connecting member 600 via a bolt assembly 800. The end of the second long bamboo beam 320 has a first connecting hole 222 and a second connecting hole 223, and is connected to the fourth connecting member 700 via a bolt assembly 800. The end of the second short bamboo beam 330 has a first connecting hole 222 and a second connecting hole 223, and is connected to the fourth connecting member 700 via a bolt assembly 800. The installation method of the first short bamboo beam 230, the second bamboo column 310, the second long bamboo beam 320, and the second short bamboo beam 330 is similar to the installation method of the first long bamboo beam 220.
