Description

Technical Field

[0001] This invention relates to a recycled low-carbon keel, specifically a recycled low-carbon keel for building wall support and its application method, belonging to the field of recycled low-carbon keel technology. Background Technology

[0002] Currently, building support systems still rely heavily on wooden building materials, resulting in a large amount of wooden construction waste that is difficult to dispose of. Wooden formwork support materials also have poor mechanical properties, affecting project quality. Furthermore, wooden materials are not readily available for customization in the market. Therefore, we need a recycled, low-carbon keel.

[0003] Chinese invention patent CN115284398B discloses a recycled low-carbon timber and its production line, including a pretreatment section, a sanding section, a wrapping section, a hardening section, a pultrusion section, and a testing section, used for dimensional determination, acceptance, and packaging of recycled timber. During processing, the surface of the wood strips is first pretreated to prevent waste from entering subsequent processes and affecting the quality of the final product. The pretreated wood strips are then spliced ​​together to form prefabricated timber. The prefabricated timber is then pre-sanded to facilitate subsequent weaving and impregnation. Sanding removes large burrs and prevents the surface from becoming too smooth, allowing for a larger contact area between the weave and adhesive during weaving, improving bonding strength and preventing delamination. This enables the reuse of waste wood strips, allowing for cutting and manufacturing on demand without relying on the original timber board dimensions. The recycled timber ensures sufficient structural strength while reducing resource waste.

[0004] As can be seen, both the existing technology for processing wooden keel strips and the above-disclosed technical solutions for processing wooden keel strips are quite cumbersome. The prepared keel strips still need to be glued multiple times before they can be used. Their environmental performance is generally poor, their support strength relies entirely on the wood material itself, and their functionality is also poor. They cannot be quickly and conveniently improved later according to different environments. Therefore, this application is made. Summary of the Invention

[0005] The purpose of this invention is to provide a recycled low-carbon keel for building wall support and its usage method in order to solve the above problems. While maintaining low cost, it reduces production steps, improves efficiency, enhances environmental performance, and also has better strength and functionality.

[0006] This invention achieves the above objectives through the following technical solution: a regenerated low-carbon keel for building wall support, comprising: Hollow columns are vertically integrated columns that can be filled with reinforcing materials or functional liquids. They can be flexibly adjusted according to the application scenario. For example, when used for traditional building wall support requiring high strength, concrete slurry can be injected inside. After the concrete slurry solidifies, a strong support structure is formed. For landscape garden wall support where lower support strength is required, an atomizing structure can be pre-installed inside. Insecticides, purified water, or other functional liquids can then be injected into the internal cavity. The liquid is atomized and discharged to the outside by a fan, greatly improving functionality with minimal modification steps. The outer wall of the hollow column has a debris filling groove for bonding wood scraps, resulting in a more aesthetically pleasing appearance after the keel strips are assembled, and also providing some sound insulation. The hollow column can be circular or polygonal; the shape is not a limitation but rather a flexible choice based on the shape of the discarded wooden keel strips. The rotary reinforcement and tightening integrated component is rotatably installed inside the hollow base column, which can divide the inner cavity of the hollow base column to form a filling cavity for filling with reinforcement materials or functional liquids; The keel strip connector is fixedly connected to the end of the rotary reinforcement and tightening integrated component that protrudes from the hollow base column. It is used to fix the wooden keel strip. The keel strip connector and the rotary reinforcement and tightening integrated component are used together. The rotary reinforcement and tightening integrated component is rotatably set inside the hollow base column. When rotating, the steel wire rope of the rotary reinforcement and tightening integrated component can be wound up, thereby gathering the keel strip connector together with the wooden keel strips fixed on the keel strip connector, so that each wooden keel strip wraps around the hollow base column in the middle.

[0007] Preferably, the hollow base column is a circular column. The outer wall of the hollow base column has a concave debris filling groove, which can be used to fill the debris removed during the processing of the waste wood keel strip, so that the appearance of the keel strip basically maintains the wood appearance. The debris filling groove has a connector limiting groove for limiting the keel strip connector, so that the keel strip connector can be more stably fixed on the circular outer wall of the hollow base column. The inner wall of the hollow base column has sliding connecting grooves distributed at the upper and lower ends for connecting the rotary reinforcement and tightening integrated component. The top through groove of the hollow base column has several symmetrically distributed snap-fit ​​grooves. The hollow base column has wire through holes evenly distributed in a ring around the rotary reinforcement and tightening integrated component.

[0008] Preferably, the hollow base column is a polygonal column. The outer wall of the hollow base column has a concave keel strip limiting groove, which allows the gathered keel strip to fit well into the keel strip limiting groove. Local gaps can be filled with debris or covered with wood-colored paint to maintain a good appearance. It is used for storing and limiting the keel strip connectors and keel plates. The inner wall of the hollow base column has sliding connection grooves distributed at the upper and lower ends for connecting the rotary reinforcement and tightening integrated component. The top through groove of the hollow base column has several symmetrically distributed snap-fit ​​grooves. The hollow base column has wire through holes that are evenly distributed in a ring around the rotary reinforcement and tightening integrated component.

[0009] Preferably, the rotary reinforcement and tightening integrated assembly consists of an upper rotating seat, a lower rotating seat, and connecting columns at both ends fixedly connected to the upper and lower rotating seats respectively. The upper and lower rotating seats are rotatably installed in sliding connecting grooves at the upper and lower ends of the inner wall of the hollow base column. Several winding wheels are evenly arranged longitudinally on the connecting columns, and a steel wire rope is fixed on each winding wheel. One end of the steel wire rope extends to the outside of the hollow base column through a steel wire through-hole. The keel strip connector is fixedly connected to the end of the steel wire rope located outside the hollow base column. In actual use, when the rotary reinforcement and tightening integrated assembly rotates, the steel wire rope can be wound up by the winding wheels, thereby pulling back the keel strip connector at one end of the steel wire rope for gathering the wooden keel strips.

[0010] Preferably, a telescopic column that cannot rotate relative to the upper rotating seat is fixedly installed on the top of the upper rotating seat. A rotating handle is fixedly installed on the top of the telescopic column, so that the rotating handle can drive the entire rotating reinforcement and tightening integrated component to rotate when it rotates. The snap-fit ​​groove opened in the through groove on the top of the hollow base column is used to snap and fix the rotating handle, which facilitates the flexible use of the rotating handle. When it is necessary to rotate the winding wheel, the rotating handle can be pulled out to break free from the restriction of the snap-fit ​​groove. When it is necessary to fix the winding wheel and the wire rope, the rotating handle can be snapped into the snap-fit ​​groove. The structure is stable and easy to use.

[0011] Preferably, the upper rotating seat is provided with a grouting port for injecting reinforcing materials or functional liquids. The upper rotating seat has an open opening, and a sealing cover is fixed to the open opening with screws. The sealing cover has a strip groove. The top of the lower rotating seat is provided with a mounting base for installing an atomizer. In actual use, if it is used for wall support in landscape gardens, an atomizer can be installed in the mounting base in advance, and a fan can be installed on the open opening. Liquids such as insecticides and purified water are injected through the grouting port. In specific applications, the liquid can be atomized by the atomizer and discharged to the outside by the fan.

[0012] Preferably, a blocking rod is fixedly installed between the lower rotating seat and the upper rotating seat. Since the end of the wire rope is fixed, the part of it that extends to the outside of the hollow foundation column will not shift, but will only contract. When the entire rotary reinforcement and tightening integrated assembly rotates, the wire rope located inside the hollow foundation column will be pulled out by the blocking rod, forming a bent state. This allows more of the wire rope to be distributed inside the hollow foundation column to form steel reinforcement ribs. The setting of the blocking rod causes the wire rope to bend during the winding process, thereby distributing it more evenly inside the hollow foundation column. This, in turn, improves the tensile strength of the concrete slurry after filling, and enhances the overall strength.

[0013] Preferably, the keel strip connector includes an arc-shaped piece with several screw holes evenly spaced on it. Screws are drilled into the back of the arc-shaped piece to connect with the wooden keel strip and fix the wooden keel strip onto the arc-shaped piece. An adhesive layer is also provided on the side wall of the arc-shaped piece. The adhesive layer can be selectively used according to actual needs and mainly plays an auxiliary role.

[0014] A method for using recycled low-carbon keel for building wall support includes the following steps: S1. Pre-treatment of wooden keel strips: The wooden keel strips to be processed are moved to the wooden construction waste extrusion processing platform by a rolling conveyor for extrusion. The wooden keel strips are processed at the same time as feeding. Then, the wooden keel strips are surface-polished, pultruded and heated by a precision grinding wheel, a pultrusion machine and a heating system. Finally, the wooden keel strips are cut into the required shape by a cutting machine. Specifically, the processing can be based on the shape of the wooden keel strips. Round wooden keel strips and sheet wooden keel strips can be used to reduce raw material waste and processing steps. The waste chips produced by polishing can be bonded to the chip filling groove to make the overall structure look more like all-wood. S2. Assemble the wooden keel strips. Pull the steel wire rope as far out as possible from the hollow base column to allow the curved piece to move flexibly outside the hollow base column. Then, attach the wooden keel strips and the curved piece close together. Drill screws into the back of the curved piece and insert the screws into the wooden keel strips to fix the curved piece to the wooden keel strips. If the wooden keel strips are columnar, they can be pre-fixed with adhesive before drilling the screws, which makes it easier to drill the screws. S3. The wooden keel strips are tightened and gathered together. The telescopic column is used to pull the rotating handle up, so that the rotating handle is freed from the restriction of the locking groove. Then, the rotating handle is rotated to control the winding wheel to rotate, thereby winding up the steel wire rope. The steel wire rope located outside the hollow base column is retracted, and the wooden keel strips connected to the keel strip connector are gathered together, forming a tight wooden structure outside the hollow base column. S4. Internal material filling: Depending on the actual application scenario, materials can be selectively filled inside the hollow column. If it is used for traditional building wall support and requires high-strength support, concrete slurry can be injected into the hollow column through the grouting port after it is installed in the designated position. After the concrete slurry solidifies, it forms a solid support structure. The strength of the concrete can be further improved due to the distribution of steel wire ropes inside. If it is used for landscape wall support and the required support strength is not high, an atomizer can be installed in the mounting base in advance. The sealing cover can be removed, a fan can be installed on the open port, and functional liquids such as insecticide and purified water can be injected through the grouting port. The liquid is atomized by the atomizer and discharged to the outside by the fan.

[0015] The beneficial effects of this invention are as follows: The keel strip of this invention is made by combining prefabricated steel structure with waste recycled wood. The prefabricated steel structure is hollow as a whole, and the investment cost is not high. Waste recycled wood is still the main material. On the one hand, waste utilization is realized and the cost is kept low. On the other hand, in the manufacturing process, only simple shape treatment of waste wood keel strips is required. There is no need to glue the wood keel strips and no additional glue is used. The production process is reduced and the environmental performance is improved. At the same time, the strength and functionality of the hollow prefabricated steel structure are greatly improved. Attached Figure Description

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please see Figures 1-9 As shown, a type of recycled low-carbon keel for building wall support includes: The hollow base column 1 is a through-type column that can be filled with reinforcing materials or functional liquids. It can be flexibly adjusted according to the application scenario. For example, when used for traditional building wall support requiring high-strength support, concrete grout can be injected inside. After the concrete grout solidifies, it forms a strong support structure. If used for landscape garden wall support where lower support strength is required, an atomizing structure can be pre-installed inside. Then, functional liquids such as insecticides or purified water can be injected into the internal cavity, and the liquids are atomized and discharged to the outside by a fan, greatly improving functionality with minimal modification steps. The outer wall of the hollow base column 1 has a debris filling groove 101, which can be used to bond wood chips, making the assembled keel strips more aesthetically pleasing and also possessing certain advantages. For sound insulation, the hollow base column 1 can be a circular or polygonal column. The shape of the hollow base column 1 is not a limitation, but rather a flexible choice based on the shape of the discarded wooden keel strips 4. If the wooden keel strip 4 is close to a column shape, it can be pre-processed into a column-like shape before assembly. In this case, choosing a column shape for the hollow base column 1 helps to splice the column-shaped wooden keel strips 4. If the discarded wooden keel strip 4 is more like a board (in this case, it is not accurate to call it a wooden keel strip 4, but it should be called a keel strip or keel board, but for the sake of understanding, it is not named separately), in order to reduce the processing steps and waste of raw materials of the wooden keel strip 4, it can be pre-processed into a sheet shape and then spliced ​​with the hollow base column 1. The rotary reinforcement and tightening integrated component 2 is rotatably installed inside the hollow base column 1, which can divide the inner cavity of the hollow base column 1 to form a filling cavity for filling with reinforcement materials or functional liquids. The keel strip connector 3 is fixedly connected to the end of the rotary reinforcement and tightening integrated component 2 that protrudes from the hollow base column 1, and is used to fix the wooden keel strips 4. The keel strip connector 3 and the rotary reinforcement and tightening integrated component 2 are used together. The rotary reinforcement and tightening integrated component 2 is rotatably installed inside the hollow base column 1. When rotating, the steel wire rope 212 of the rotary reinforcement and tightening integrated component 2 can be wound up, thereby gathering the keel strip connector 3 together with the wooden keel strips 4 fixed on the keel strip connector 3, so that each wooden keel strip 4 wraps around the central hollow base column 1. The keel strip of this invention is made by combining prefabricated steel structure with waste recycled wood. The structure is hollow, and the investment cost is not high. It still uses recycled waste wood as the main material, which realizes waste utilization and keeps the cost low. On the other hand, the manufacturing process only requires simple shaping of the waste wood keel strips 4. There is no need to glue the wood keel strips 4 together or use additional glue. The production process is reduced and the environmental performance is improved. At the same time, the strength and functionality of the hollow prefabricated steel structure, namely the hollow base column 1 and the rotary reinforcement and tightening integrated component 2, are greatly improved. Compared with traditional keel strips, this invention maintains low cost, reduces production processes, improves efficiency, strengthens environmental performance, and has better strength and functionality.

[0028] Preferably, the rotary reinforcement and tightening integrated component 2 consists of an upper rotating seat 201, a lower rotating seat 202, and a connecting column 203 with both ends fixedly connected to the upper rotating seat 201 and the lower rotating seat 202, respectively. The upper rotating seat 201 and the lower rotating seat 202 are rotatably installed in the sliding connecting grooves 104 at the upper and lower ends of the inner wall of the hollow base column 1, respectively. Several winding wheels 204 are evenly arranged longitudinally on the connecting column 203. A steel wire rope 212 is fixed on each winding wheel 204. One end of the steel wire rope 212 extends to the outside of the hollow base column 1 through the steel wire through hole 103. The keel strip connector 3 is fixedly connected to the end of the steel wire rope 212 located outside the hollow base column 1. In actual use, when the rotary reinforcement and tightening integrated component 2 rotates, the steel wire rope 212 can be wound up by the winding wheel 204, thereby pulling back the keel strip connector 3 at one end of the steel wire rope 212 for gathering the wooden keel strips 4.

[0029] Preferably, a telescopic column 206 that cannot rotate relative to the upper rotating seat 201 is fixedly installed on the top of the upper rotating seat 201. A rotating handle 207 is fixedly installed on the top of the telescopic column 206, so that the rotating handle 207 can drive the entire rotating reinforcement and tightening integrated component 2 to rotate when rotating. The snap-fit ​​groove 105 opened in the through groove on the top of the hollow base column 1 is used to snap and fix the rotating handle 207, which facilitates the flexible use of the rotating handle 207. When it is necessary to rotate the winding wheel, the rotating handle 207 can be pulled out and released from the restriction of the snap-fit ​​groove 105. When it is necessary to fix the winding wheel and the wire rope 212, the rotating handle 207 can be snapped into the snap-fit ​​groove 105. The structure is stable and easy to use.

[0030] Preferably, the upper rotating seat 201 is provided with a grouting port 209 for injecting reinforcing materials or functional liquids. The upper rotating seat 201 has an open opening, and a sealing cover 205 is fixed to the open opening by screws. The sealing cover 205 has a strip groove 210. The top of the lower rotating seat 202 is provided with a mounting base 211, which can be used to install an atomizer. In actual use, if it is used for wall support in landscape gardens, an atomizer can be installed in the mounting base 211 in advance, and a fan can be installed on the open opening. Liquids such as insecticides and purified water can be injected through the grouting port 209. In specific applications, the liquid can be atomized by the atomizer and discharged to the outside by the fan.

[0031] Preferably, a blocking rod 208 is also fixedly provided between the lower rotating seat 202 and the upper rotating seat 201. Since the protruding end of the steel wire rope 212 is fixed, the part of it that protrudes to the outside of the hollow base column 1 will not shift, but will only contract. When the rotary reinforcement and tightening integrated assembly 2 rotates as a whole, the steel wire rope 212 located inside the hollow base column 1 will be pulled out by the blocking rod 208 and form a bent state, so that more of the steel wire rope 212 is distributed inside the hollow base column 1 to form steel reinforcement. The setting of the blocking rod 208 causes the steel wire rope 212 to bend during the winding process, thereby distributing it more evenly inside the hollow base column 1, thereby improving the tensile strength of the concrete slurry after filling, and improving the overall strength.

[0032] Preferably, the keel strip connector 3 includes an arc-shaped piece 301, on which a plurality of screw holes 302 are evenly opened. Screws are drilled into the back of the arc-shaped piece 301 to connect with the wooden keel strip 4 to fix the wooden keel strip 4 onto the arc-shaped piece 301. An adhesive layer 303 is also provided on the side wall of the arc-shaped piece 301. The adhesive layer 303 can be selectively used according to actual needs and mainly plays an auxiliary role.

[0033] Example 1

[0034] The hollow base column 1 is a circular column. The outer wall of the hollow base column 1 has a concave debris filling groove 101, which can be used to glue and fill the debris removed during the processing of the waste wood keel strip 4, so that the appearance of the keel strip basically maintains the appearance of wood. The debris filling groove 101 has a connector limiting groove 102 for limiting the keel strip connector 3, so that the keel strip connector 3 can be more stably fixed on the circular outer wall of the hollow base column 1. The inner wall of the hollow base column 1 has sliding connecting grooves 104 distributed at the upper and lower ends for connecting the rotary reinforcement and tightening integrated component 2. The top through groove of the hollow base column 1 has several symmetrically distributed snap-fit ​​grooves 105. The hollow base column 1 has wire through holes 103 evenly distributed in a ring around the rotary reinforcement and tightening integrated component 2.

[0035] In this embodiment, a method for using recycled low-carbon keel for building wall support is described. The wooden keel strip 4 used in this embodiment is columnar, and the method includes the following steps: S1. Pre-treatment of wooden keel strips 4: The wooden keel strips 4 to be processed are moved to the wooden construction waste extrusion processing platform by the wooden construction waste rolling conveyor for extrusion. The wooden keel strips 4 can be processed at the same time as feeding. Then, the wooden keel strips 4 are surface-polished, pultruded and heated by the precision grinding mold, the co-extrusion equipment and the heating system. Finally, the wooden keel strips 4 are cut into the required shape by the cutting equipment. The waste chips produced by polishing can be bonded into the chip filling groove 101 to make the overall structure look more like all-wood. S2. Assemble the wooden keel strip 4. Pull the steel wire rope 212 as far out as possible from the hollow base column 1 so that the arc-shaped piece 301 can move flexibly outside the hollow base column 1. Then, attach the wooden keel strip 4 and the arc-shaped piece 301 close together and fix them in advance through the adhesive layer 303. Then, drill screws into the back of the arc-shaped piece 301 and drill the screws into the wooden keel strip 4 to fix the arc-shaped piece 301 and the wooden keel strip 4. S3. The wooden keel strips 4 are tightened and gathered together. The telescopic column 206 is used to pull up the rotating handle 207, so that the rotating handle 207 is freed from the restriction of the locking groove 105. Then, by rotating the rotating handle 207, the winding wheel 204 is controlled to rotate, thereby winding up the steel wire rope 212. The steel wire rope 212 located outside the hollow base column 1 is retracted, and the wooden keel strips 4 connected to the keel strip connector 3 are gathered together, forming a tight wooden structure outside the hollow base column 1. S4. Internal material filling: Depending on the actual application scenario, materials can be selectively filled inside the hollow base column 1. If it is used for traditional building wall support and requires high-strength support, concrete slurry can be injected into the hollow base column 1 through the grouting port 209 after it is installed in the designated position. After the concrete slurry solidifies, a solid support structure is formed. The strength of the concrete can be further improved due to the distribution of the steel wire rope 212. If it is used for landscape garden wall support and the required support strength is not high, an atomizer can be installed in the mounting base 211 in advance. The sealing cover 205 can be removed, and a fan can be installed on the open opening. Functional liquids such as insecticide and purified water can be injected through the grouting port 209. The liquid is atomized by the atomizer and discharged to the outside by the fan.

[0036] Example 2

[0037] The hollow base column 1 is a polygonal column. The outer wall of the hollow base column 1 has a concave keel strip limiting groove 106, which allows the folded keel plate to fit well in the keel strip limiting groove 106. Local gaps can be filled with debris or covered with wood-colored paint to maintain a good appearance. It is used for the storage and limiting of the keel strip connector 3 and the keel plate. The inner wall of the hollow base column 1 has sliding connection grooves 104 distributed at the upper and lower ends for connecting the rotary reinforcement and tightening integrated component 2. The top through groove of the hollow base column 1 has several symmetrically distributed snap-fit ​​grooves 105. The hollow base column 1 has wire through holes 103 evenly distributed in a ring around the rotary reinforcement and tightening integrated component 2.

[0038] In this embodiment, a method for using recycled low-carbon keel for building wall support, wherein the wooden keel strip 4 is in the form of a board, includes the following steps: S1. Pre-treatment of wooden keel strip 4: The wooden keel strip 4 to be processed is moved to the wooden construction waste extrusion processing platform by the wooden construction waste rolling conveyor for extrusion. The wooden keel strip 4 can be processed at the same time as feeding. Then, the wooden keel strip 4 is surface polished, pultruded and heated by the precision grinding mold, the co-extrusion equipment and the heating system. Finally, the wooden keel strip 4 is cut into the required shape by the cutting equipment. S2. Assemble the wooden keel strip 4. Pull the steel wire rope 212 as far out as possible from the hollow base column 1 so that the arc-shaped piece 301 can move flexibly outside the hollow base column 1. Then, attach the wooden keel strip 4 and the arc-shaped piece 301 close together. Then, drill screws into the back of the arc-shaped piece 301 and drill screws into the wooden keel strip 4 so that the arc-shaped piece 301 and the wooden keel strip 4 are fixedly connected, so that the wooden keel strip 4 is fixed on the arc-shaped piece 301. S3. The wooden keel strips 4 are tightened and gathered together. The telescopic column 206 is used to pull up the rotating handle 207, so that the rotating handle 207 is released from the restriction of the locking groove 105. Then, by rotating the rotating handle 207, the winding wheel 204 is rotated, which in turn winds up the steel wire rope 212. The steel wire rope 212 located outside the hollow base column 1 is retracted, and the wooden keel strips 4 connected to the keel strip connector 3 are gathered together. The wooden keel strips 4 enter the keel strip limiting groove 106 and fit together, forming a tight wooden structure on the outside of the hollow base column 1. The gaps can be sprayed with wood-colored paint to cover the metallic color. S4. Internal material filling: Depending on the actual application scenario, materials can be selectively filled inside the hollow base column 1. If it is used for traditional building wall support and requires high-strength support, concrete slurry can be injected into the hollow base column 1 through the grouting port 209 after it is installed in the designated position. After the concrete slurry solidifies, a solid support structure is formed. The strength of the concrete can be further improved due to the distribution of the steel wire rope 212. If it is used for landscape garden wall support and the required support strength is not high, an atomizer can be installed in the mounting base 211 in advance. The sealing cover 205 can be removed, and a fan can be installed on the open opening. Functional liquids such as insecticide and purified water can be injected through the grouting port 209. The liquid is atomized by the atomizer and discharged to the outside by the fan.

An adhesive layer (303) is also provided on the side wall of the arc-shaped piece (301).

9. A method of using recycled low-carbon keel for building wall support as described in any one of claims 1-8, characterized in that, Includes the following steps: S1. Pre-treatment of wooden keel strips (4): The wooden keel strips (4) to be treated are moved to the wooden construction waste extrusion platform by the wooden construction waste rolling conveyor for extrusion. The wooden keel strips (4) can be processed at the same time as feeding. Then, the wooden keel strips (4) are surface polished, pultruded and heated by the precision grinding tool, the collaborative pultrusion equipment and the heating system. Finally, the wooden keel strips (4) are cut into the required shape by the cutting equipment. Specifically, the wooden keel strips (4) can be processed according to their shape. Both round wooden keel strips (4) and sheet-shaped wooden keel strips (4) can be used. S2. Assemble the wooden keel strip (4). Pull the steel wire rope (212) as far out as possible from the hollow base column (1) so that the arc plate (301) can move flexibly outside the hollow base column (1). Then, bring the wooden keel strip (4) and the arc plate (301) close together. Then, drill screws into the back of the arc plate (301) and drill screws into the wooden keel strip (4) so ​​that the arc plate (301) and the wooden keel strip (4) are fixedly connected. Fix the wooden keel strip (4) on the arc plate (301). If the wooden keel strip (4) is columnar, it can also be fixed in advance through the adhesive layer (303). S3. The wooden keel strips (4) are tightened and gathered together. The telescopic column (206) is used to pull up the rotating handle (207), so that the rotating handle (207) is freed from the restriction of the snap-fit ​​groove (105). Then, the rotating handle (207) is rotated to control the winding wheel (204) to rotate, thereby winding up the wire rope (212). The wire rope (212) located outside the hollow base column (1) is retracted, and the wooden keel strips (4) connected to the keel strip connector (3) are gathered together, forming a tight wooden structure outside the hollow base column (1). S4. Internal material filling: Depending on the actual application scenario, materials can be selectively filled inside the hollow column (1). If it is used for traditional building wall support and requires high-strength support effect, concrete slurry is injected into the hollow column (1) through the grouting port (209) after it is installed in the designated position. After the concrete slurry solidifies, a support structure is formed. If it is used for landscape garden wall support and the required support strength is not high, an atomizer can be installed in the mounting base (211) in advance, the sealing cover (205) is removed, a fan is installed on the open opening, and functional liquids such as insecticide and pure water are injected through the grouting port (209). The liquid is atomized by the atomizer and discharged to the outside by the fan.
