Description

Technical Field

[0001] The invention belongs to the technical field of wooden structure buildings, and particularly relates to a method for constructing a guardrail for a wooden structure building. Background Art

[0002] Among numerous building materials, wood is the only natural material that is renewable and can be recycled multiple times. Besides providing a sense of comfort, warmth, and intimacy, wood also contributes to a healthy living environment. Furthermore, as a building material, wood boasts advantages such as lightness, high strength, excellent earthquake resistance, and ease of processing. The widespread use of wood structures is a hallmark of traditional Chinese architecture, such as temples.

[0003] Wooden structural columns are upright rods used to support the weight of the upper part of a building. Like most other building components, wooden structural columns have a rich variety and a certain development process.

[0004] In traditional Chinese architecture, technicians install guardrails between wooden columns. The guardrails serve the functions of safety protection, isolation and decoration, highlighting the characteristics of ancient Chinese architecture.

[0005] If wooden guardrails are used, they are prone to rotting and structural damage under long-term exposure to the external environment. Therefore, steel guardrails are used. If the steel guardrails are fixed directly to the wooden columns with screws, it is easy to damage the bottom structure of the wooden columns and weaken the bottom load-bearing capacity of the wooden columns. In addition, the steel guardrails are directly loaded on the wooden columns, which can easily cause structural damage to the wooden columns. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems existing in the prior art and to provide a method for constructing guardrails for timber structures. This method can achieve a fixed connection between steel guardrails and timber columns without damaging the timber columns. Furthermore, it can protect the bottoms of the timber columns, improving their load-bearing capacity and meeting the installation requirements for steel guardrails of a certain weight. Furthermore, the constructed steel guardrails can be aligned or distributed at angles, making them suitable for installation between timber columns with different distributions, thus providing a wide range of applications.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A method for constructing a guardrail for a wooden structure building, characterized by comprising the following steps:

[0009] a. According to the construction drawings, a steel structure guardrail is manufactured in the processing plant and serves as an installation unit between two adjacent wooden structure columns.

[0010] b. Measure and lay out the timber columns according to the construction drawings, marking the installation locations for the inner steel plates and the steel guardrails. This invention uses three timber columns as an example; the specific number will be adjusted based on the construction site. This invention can be constructed with the three timber columns aligned, in which case the steel guardrails are aligned. It can also be constructed with the three timber columns not aligned, resulting in an angled arrangement between adjacent steel guardrails.

[0011] c. Install the limiting structure:

[0012] (1) Embedded bolt installation:

[0013] According to the installation position of the inner steel plate, grooves are cut on the ground, embedded bolts are set in the grooves, and then cement mortar is filled into the grooves to fix the embedded bolts on the ground. The length of the embedded bolts extending into the ground is set according to the weight of the inner steel plate.

[0014] (2) Set the pad onto the embedded bolts, screw the lock nuts onto the embedded bolts, fix the pad to the ground, and then weld the positioning blocks on top of the embedded bolts.

[0015] d. Fix the inner steel plate on the outside of the wooden structure column:

[0016] (1) Select an inner steel plate of a set size and shape. The inner steel plate is semicircular and can wrap around the wooden column, protecting the bottom of the wooden column and increasing the load-bearing capacity of the wooden column. Then fix a limit block on the outside of the inner steel plate, and the limit block has a limit groove.

[0017] (2) Attach the two inner steel plates to the outside of the wooden structure column, then move the inner steel plates from top to bottom, connect the limit slots and positioning blocks of the limit blocks, and support the inner steel plates on the ground.

[0018] (3) Weld the contact points of the two inner steel plates of the same wooden structure column so that the two inner steel plates are connected into an integral structure.

[0019] e. Install the steel structure adjustment frame on the outer steel plate:

[0020] (1) Select an outer steel plate of set size and shape. The outer steel plate includes a top plate and an outer plate. The top plate is set on the top of the outer plate. The top plate is provided with a notch, a cement mortar injection hole and a guide hole. A cavity is formed between the top plate and the outer plate.

[0021] (2) Select a steel structure adjustment frame, which includes a steel structure main body, a guide block and a threaded rod fixed at the bottom of the steel structure main body, a connecting plate provided on the connecting surface of the steel structure main body, and a connecting column fixed on the top of the connecting plate.

[0022] (3) Insert the guide block of the steel structure adjustment frame into the cement mortar injection hole, and at the same time insert the threaded rod into the guide hole. Support the main steel structure on the top plate, and then screw the limit nut into the threaded rod. The limit nut is set below the top plate. The limit nut is not tightened to prevent the entire steel structure adjustment frame from falling off the outer steel plate. When the guide block moves in the cement mortar injection hole and the threaded rod moves in the guide hole, the steel structure adjustment frame rotates on the outer steel plate with the center of the wooden column as the center of the circle.

[0023] f. Fix the outer steel plate on the outer side of the inner steel plate: clamp the notch of the outer steel plate on the outer side of the inner steel plate, weld the outer steel plate and the inner steel plate, and then weld the contact points of the two outer steel plates on the same wooden structure column to make the two outer steel plates sealed and connected.

[0024] Considering that the two outer steel plates of the same wooden structure column form a sealed structure and cannot be installed on the threaded rod and the limit nut is screwed in, it is necessary to install a steel structure adjustment frame on the outer steel plate before fixing the outer steel plate on the outside of the inner steel plate to control the limit nut to be in the position of the threaded rod.

[0025] g. Install the fixed steel plate on the steel structure adjustment frame:

[0026] (1) Inject cement mortar into the cavity through the cement mortar injection hole. Fill the entire cavity with cement mortar and overflow from the cement mortar injection hole. Then rotate the steel structure adjustment frame. The steel structure main body scrapes off the overflowed cement mortar so that the top surface of the cement mortar is flush with the top surface of the top plate. Then rotate the steel structure adjustment frame to the set position. After the cement mortar solidifies, fix the steel structure adjustment frame on the outer steel plate and weld the contact between the steel structure main body and the top plate.

[0027] (2) Weld an ear plate on the side of the fixed steel plate. The ear plate is provided with a through hole. Then install the fixed steel plate on the connecting plate. The connecting column passes through the through hole of the ear plate. Then screw the fixing nut into the connecting column. Then rotate the ear plate on the connecting column so that the fixed steel plate rotates on the steel structure adjustment frame. Set the fixed steel plates on the two adjacent wooden structure columns in parallel. Then tighten the fixing nut to fix the ear plate on the connecting plate.

[0028] The steel structure guardrail of the present invention is installed on the steel structure adjustment frame, and the steel structure adjustment frame is the main force-bearing component. If the steel structure adjustment frame is only welded to the outer steel plate, the welding point between the steel structure adjustment frame and the outer steel plate will easily crack when the steel structure guardrail is installed. Therefore, it is necessary to extend the guide block and the threaded rod into the cement mortar injected into the cavity to increase the firmness of the connection between the steel structure adjustment frame and the outer steel plate, thereby improving the force-bearing capacity of the steel structure adjustment frame.

[0029] If no inner steel plate is installed, the cement mortar will easily destroy the structure of the wooden column when injecting cement mortar. Therefore, the inner steel plate is used to wrap the wooden column, and cement mortar is filled between the inner and outer steel plates. This can increase the overall weight and improve the bearing capacity of the wooden column. At the same time, when the cement mortar solidifies, the cement mortar is connected to the steel structure adjustment frame, which increases the stability of the steel structure adjustment frame and facilitates the quick installation of the steel structure guardrail. Moreover, the cement mortar fills the entire cavity, increases the strength of the inner and outer steel plates, and is not easily deformed.

[0030] If the present invention is only used to install steel structure guardrails between wooden structure columns that are on the same straight line, there is no need to rotate the steel structure adjustment frame or the fixed steel plate, so the scope of application is small. To address this technical problem, the steel structure adjustment frame is rotated on the outer steel plate with the center of the wooden structure column as the center of the circle, and then the fixed steel plate is rotated on the steel structure adjustment frame. According to the distribution of the wooden structure columns, the position of the fixed steel plate is adjusted so that the fixed steel plates on two adjacent wooden structure columns are arranged in parallel to fix a single steel structure guardrail. The steel structure guardrails after construction can be on the same straight line or distributed at an angle. It is suitable for installing steel structure guardrails between wooden structure columns with different distributions and has a wide range of applications. With the rotation of the steel structure adjustment frame, the guide block moves in the cement mortar injection hole, and the threaded rod moves in the guide hole, so that the steel structure adjustment frame rotates in a directional manner, thereby improving stability.

[0031] h. Install a single steel structure guardrail between the fixed steel plates on two adjacent wooden structure columns, and then weld the steel structure guardrail and the fixed steel plates.

[0032] Each steel guardrail is manufactured in a factory, which shortens the construction period and ensures that the prefabrication quality of the steel guardrail is controlled. This solves the technical problem of securely attaching the wooden columns to the steel guardrail without damaging the wooden columns.

[0033] i. Paint the outer steel plate, and then paint the fixed steel plate, steel structure guardrail and steel structure adjustment frame. This can protect the outer steel plate, fixed steel plate, steel structure guardrail and steel structure adjustment frame, and at the same time make them aesthetically pleasing.

[0034] Furthermore, the steel structure guardrail includes two guardrail panels, which are vertically clamped by a clamp to determine the width of the steel structure guardrail. Then, according to the distance between the two guardrail panels, a partition panel 1 is cut to obtain the partition panel 1. The partition panel 1 is horizontally installed between the two guardrail panels while maintaining the set distance, and the guardrail panel and the partition panel 1 are welded. Then, according to the distance between the two partition panels 1 below, a partition panel 2 is cut to obtain the partition panel 2. A vertical partition panel 2 is welded between the two partition panels 1 below, and then a decorative piece 1 is welded between the two guardrail panels, and a decorative piece 2 is welded between the two partition panels 1 above to make a steel structure guardrail. The steel structure guardrail has high structural strength, is convenient for installing decorative piece 1 and decorative piece 2, and improves aesthetics. Decorative piece 2 is oval in shape, and an introduction board can be placed inside to introduce the history and culture of the ancient building.

[0035] Furthermore, after step b is completed, according to the construction drawings, holes are drilled in the ground, steel bars are inserted into the holes, and cement mortar is filled in the holes to fix the steel bars on the ground. When step f is completed, the steel bars are placed in the cavity. When cement mortar is injected into the cavity through the cement mortar injection hole, the cement mortar and the steel bars are combined and fixed, thereby increasing the strength of the solidified cement mortar.

[0036] Furthermore, the limiting block is fixed in the following manner: a connecting block is welded to the outer side of the inner steel plate, and a fixing bolt is screwed between the threaded hole of the limiting block and the threaded hole of the connecting block, so that the limiting block can be detachably connected to the outer side of the inner steel plate.

[0037] Furthermore, in step e, before the guide block of the steel structure adjustment frame is extended into the cement mortar injection hole, a reinforcing plate is welded at the corner of the steel structure body to increase the strength of the steel structure adjustment frame.

[0038] Furthermore, the top plate and the outer peripheral plates of the outer steel plate are formed integrally by stamping, which makes the outer steel plate simple to manufacture and easy to control the shape of the outer steel plate, while the strength of the outer steel plate is relatively high.

[0039] Furthermore, a water outlet is provided at the bottom of the outer plate. Before injecting cement mortar into the cavity through the cement mortar injection hole, the water outlet is first blocked with a plug. Then, clean water is poured into the cavity through the cement mortar injection hole for curing. The plug is then removed from the water outlet, the clean water is drained out, and the water outlet is blocked again with the plug. Finally, cement mortar is injected into the cavity through the cement mortar injection hole. Before injecting the cement mortar, the area between the outer plate and the inner plate can be moistened to appropriately increase the fluidity of the cement mortar, allowing the cement mortar to quickly fill the entire cavity. Impurities between the outer plate and the inner plate can also be discharged, preventing the formation of holes in the cured cement mortar, which would affect the strength of the cement mortar.

[0040] Furthermore, after step g is completed, two fixing blocks are welded on the top surface of the top plate, the steel structure body is set between the two fixing blocks, and then the steel structure body and the fixing blocks are welded to increase the firmness of the connection between the steel structure adjustment frame and the outer plate, thereby improving the force-bearing capacity of the steel structure adjustment frame.

[0041] Furthermore, during the process of injecting cement mortar into the cavity through the cement mortar injection hole, iron wire is tied to the outside of the outer steel plate. When the cement mortar is solidified, the iron wire is removed to prevent the outer steel plate from deforming when injecting the cement mortar.

[0042] Furthermore, the color of the paint applied to the outer side of the outer steel plate is the same as the color of the wooden structure column, thereby improving the aesthetics.

[0043] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0044] (1) The present invention uses an inner steel plate to wrap the wooden structure column, and fills cement mortar between the inner steel plate and the outer steel plate, which can increase the overall weight and improve the load-bearing capacity of the wooden structure column; at the same time, the guide block and the threaded rod extend into the cement mortar injected into the cavity. When the cement mortar solidifies, the cement mortar and the steel structure adjustment frame are connected, and at the same time, the steel structure adjustment frame and the outer steel plate are welded and fixed, which increases the stability of the steel structure adjustment frame, improves the load-bearing capacity of the steel structure adjustment frame, meets the installation requirements of steel structure guardrails of a certain weight, and facilitates and quickly installs the steel structure guardrail; moreover, the cement mortar fills the entire cavity, which can increase the strength of the inner steel plate and the outer steel plate, is not easy to deform, and is used for tourists to rest.

[0045] (2) If the present invention is only used to install steel structure guardrails between wooden structure columns that are on the same straight line, there is no need to rotate the steel structure adjustment frame or the fixed steel plate, so the scope of application is small.

[0046] To address this technical issue, the steel structure adjustment frame rotates on the outer steel plate with the center of the wooden column as the center of the circle, which then causes the fixed steel plate to rotate on the steel structure adjustment frame. The position of the fixed steel plate is adjusted according to the distribution of the wooden columns, so that the fixed steel plates on two adjacent wooden columns are arranged in parallel, which is used to fix a single steel structure guardrail. After construction, the steel structure guardrails can be located on the same straight line or distributed at an angle, which is suitable for installing steel structure guardrails between wooden columns with different distributions, and has a wide range of applications. During the rotation of the steel structure adjustment frame, the guide block moves in the cement mortar injection hole, and the threaded rod moves in the guide hole, which makes the steel structure adjustment frame rotate in a directional manner and improves stability.

[0047] Moreover, the rotation of the steel structure adjustment frame can scrape off the overflowed cement mortar, making the top surface of the cement mortar flush with the top surface of the top plate, improving the aesthetics, and facilitating the subsequent connection and fixation between the steel structure adjustment frame and the outer steel plate.

[0048] (3) The present invention prefabricates the steel structure guardrail in a processing plant and delivers the entire steel structure guardrail to the construction site, which can shorten the construction period and control the prefabrication quality of the steel structure guardrail.

[0049] (4) The present invention solves the technical problem of securely mounting the wooden columns and the steel guardrail without damaging the structure of the wooden columns. This makes the steel guardrail corrosion-resistant and high-strength. An introduction sign can be placed on the steel guardrail to introduce the ancient building, while also enhancing its aesthetics.

[0050] (5) The inner and outer steel plates of the present invention are limited on the ground. During the process of filling cement mortar between the inner and outer steel plates, the inner and outer steel plates will not rotate, thereby avoiding damage to the bottom structure of the wooden structure column.

DETAILED DESCRIPTION

[0069] like Figures 1 to 16 The figure shows a method for constructing a guardrail for a timber structure building according to the present invention. This method uses three timber columns 1 as an example, and the specific number can be adjusted based on the construction site. The method can be used when the three timber columns 1 are aligned, in which case the steel guardrails 30 are aligned. Alternatively, the method can be used when the three timber columns 1 are not aligned, in which case adjacent steel guardrails 30 are arranged at an angle.

[0070] The present invention comprises the steps of:

[0071] a. According to the construction drawings, a steel structure guardrail 30 is manufactured in a processing plant and serves as an installation unit between two adjacent wooden structure columns 1.

[0072] The steel guardrail 30 includes two guardrail panels 31. A clamp is used to vertically clamp the two guardrail panels 31 to determine the width of the steel guardrail 30. Then, a partition panel 1 32 is cut based on the distance between the two guardrail panels 31. The partition panel 1 32 is horizontally inserted between the two guardrail panels 31, maintaining the set distance. The guardrail panels 31 and partition panel 1 32 are then welded together. A partition panel 2 33 is cut based on the distance between the two lower partition panels 1 32. A vertical partition panel 2 33 is welded between the two lower partition panels 1 32. A decorative piece 1 35 is welded between the two guardrail panels 31, and a decorative piece 2 34 is welded between the two upper partition panels 1 32. The decorative piece 2 34 is oval in shape and can be used to place an information sign inside to introduce the history and culture of the ancient building. The resulting steel guardrail 30 has high structural strength, facilitates the installation of decorative pieces 1 35 and 2 34, and enhances its aesthetics.

[0073] b. According to the construction drawings, measure and set out the wooden structure column 1, and mark the installation position of the inner steel plate 7 and the installation position of the steel structure guardrail 30.

[0074] Then, according to the construction drawings, holes are drilled in the ground, the steel bars 6 are inserted into the holes, and cement mortar is filled in the holes to fix the steel bars 6 on the ground.

[0075] c. Install the limiting structure:

[0076] (1) Installation of embedded bolt 2:

[0077] According to the installation position of the inner steel plate 7, a groove is cut on the ground, and then an embedded bolt 2 is set in the groove. Then cement mortar is filled into the groove to fix the embedded bolt 2 on the ground. The length of the embedded bolt 2 extending into the ground is set according to the weight of the inner steel plate 7.

[0078] (2) Set the pad 4 on the embedded bolt 2, then screw the locking nut 3 into the embedded bolt 2, fix the pad 4 on the ground, and then weld the positioning block 5 on the top of the embedded bolt 2. The pad 4 can improve the stability of the embedded bolt 2 and meet the installation requirements of the positioning block 5.

[0079] d. Fix the inner steel plate 7 on the outside of the wooden structure column 1:

[0080] (1) Select an inner steel plate 7 of a set size and shape. The inner steel plate 7 is semicircular and can wrap around the wooden column 1, protecting the bottom of the wooden column 1 and increasing the load-bearing capacity of the wooden column 1. Then, fix a limit block 9 on the outside of the inner steel plate 7. The limit block 9 is provided with a limit groove 11.

[0081] The limiting block 9 is fixed in the following manner: a connecting block 8 is welded to the outer side of the inner steel plate 7 , and a fixing bolt 10 is screwed between the threaded hole of the limiting block 9 and the threaded hole of the connecting block 8 , so that the limiting block 9 can be detachably connected to the outer side of the inner steel plate 7 .

[0082] (2) Attach the two inner steel plates 7 to the outer side of the wooden structure column 1, then move the inner steel plates 7 from top to bottom, interlock the limiting grooves 11 of the limiting blocks 9 and the positioning blocks 5, and support the inner steel plates 7 on the ground.

[0083] (3) The contact points of the two inner steel plates 7 of the same wooden structure column 1 are welded so that the two inner steel plates 7 are connected into an integral structure. At this time, the inner steel plates are limited on the ground to avoid damage to the wooden structure column 1 when filling cement mortar later.

[0084] e. Install the steel structure adjustment frame on the outer steel plate 12:

[0085] (1) An outer steel plate 12 of a predetermined size and shape is selected. The outer steel plate 12 includes a top plate 21 and an outer plate 22. The top plate 21 is located on top of the outer plate 22. The top plate 21 and the outer plate 22 of the outer steel plate 12 are formed integrally by stamping, which makes the outer steel plate 12 simple to manufacture and easy to control the shape of the outer steel plate 12. At the same time, the outer steel plate 12 has a high strength. The top plate 21 is provided with a notch 26, a cement mortar injection hole 24, and a guide hole 25. A cavity 23 is formed between the top plate 21 and the outer plate 22.

[0086] (2) A steel structure adjustment frame is selected. The steel structure adjustment frame includes a steel structure body 13. A guide block 28 and a threaded rod 27 are fixed to the bottom of the steel structure body 13. A connecting plate 17 is provided on the connecting surface of the steel structure body 13. A connecting column 14 is fixed to the top of the connecting plate 17. Reinforcement plates 20 are welded at the corners of the steel structure body 13 to increase the strength of the steel structure adjustment frame.

[0087] (3) Insert the guide block 28 of the steel structure adjustment frame into the cement mortar injection hole 24, and insert the threaded rod 27 into the guide hole 25 at the same time, and support the steel structure main body 13 on the top plate 21. Then screw the limit nut 29 into the threaded rod 27. The limit nut 29 is set below the top plate 21. The limit nut 29 is not locked to prevent the entire steel structure adjustment frame from falling off the outer steel plate 12. When the guide block 28 moves in the cement mortar injection hole 24 and the threaded rod 27 moves in the guide hole 25, the steel structure adjustment frame rotates on the outer steel plate 12 with the center of the wooden structure column 1 as the center of the circle.

[0088] f. Fix the outer steel plate 12 to the outer side of the inner steel plate 7: Fit the notches 26 of the outer steel plate 12 onto the outer side of the inner steel plate 7 and weld the outer steel plate 12 to the inner steel plate 7. Then, weld the contact points of the two outer steel plates 12 on the same wooden column 1 to seal the two outer steel plates 12 together. The steel bars 6 are placed in the cavity 23.

[0089] Considering that the two outer steel plates 12 of the same wooden structure column 1 form a sealed structure, it is impossible to install the limit nut 29 on the threaded rod 27 and screw it into the limit nut. Therefore, before fixing the outer steel plate 12 on the outside of the inner steel plate 7, it is necessary to install a steel structure adjustment frame on the outer steel plate 12 to control the limit nut 29 to be in the position of the threaded rod 27.

[0090] g. Install the fixed steel plate 18 on the steel structure adjustment frame:

[0091] (1) Tie iron wire to the outside of the outer steel plate 12, and then inject cement mortar into the cavity 23 through the cement mortar injection hole 24. The cement mortar fills the entire cavity 23 and overflows from the cement mortar injection hole 24. The iron wire can prevent the outer steel plate 12 from deforming when the cement mortar is injected. Then rotate the steel structure adjustment frame, and the steel structure main body 13 will scrape off the overflowing cement mortar so that the top surface of the cement mortar is flush with the top surface of the top plate 21. Then turn the steel structure adjustment frame to the set position. After the cement mortar solidifies, fix the steel structure adjustment frame on the outer steel plate 12, and then weld the contact between the steel structure main body 13 and the top plate 21. When the cement mortar solidifies, remove the iron wire.

[0092] When cement mortar is injected into the cavity 23 through the cement mortar injection hole 24 , the cement mortar and the steel bars 6 are combined and fixed, thereby increasing the strength of the cement mortar after solidification.

[0093] (2) Weld the ear plate 16 on the side of the fixed steel plate 18. The ear plate 16 is provided with a through hole. Then install the fixed steel plate 18 on the connecting plate 17. The connecting column 14 passes through the through hole of the ear plate 16. Then screw the fixing nut 15 into the connecting column 14. Then rotate the ear plate 16 on the connecting column 14 so that the fixed steel plate 18 rotates on the steel structure adjustment frame. Set the fixed steel plates 18 on the two adjacent wooden structure columns 1 in parallel. Then tighten the fixing nut 15 to fix the ear plate 16 on the connecting plate 17.

[0094] The steel structure guardrail 30 of the present invention is installed on the steel structure adjustment frame, which is the main load-bearing component. If the steel structure adjustment frame is only welded to the outer steel plate 12, the weld between the steel structure adjustment frame and the outer steel plate 12 will easily crack when the steel structure guardrail 30 is installed. Therefore, it is necessary to extend the guide block 28 and the threaded rod 27 into the cement mortar injected into the cavity 23 to increase the firmness of the connection between the steel structure adjustment frame and the outer steel plate 12 and improve the load-bearing capacity of the steel structure adjustment frame.

[0095] If the inner steel plate 7 is not provided, the cement mortar will easily destroy the structure of the wooden structure column 1 when injecting the cement mortar. Therefore, the inner steel plate 7 is used to wrap the wooden structure column 1, and the cement mortar is filled between the inner steel plate 7 and the outer steel plate 12, which can increase the overall weight and improve the force-bearing capacity of the wooden structure column 1. At the same time, when the cement mortar is cured, the cement mortar is connected to the steel structure adjustment frame, which increases the stability of the steel structure adjustment frame and facilitates the quick installation of the steel structure guardrail 30. Moreover, the cement mortar fills the entire cavity 23, increases the strength of the inner steel plate 7 and the outer steel plate 12, and is not easily deformed.

[0096] If the present invention is only used to install steel structure guardrails 30 between wooden structure columns 1 that are on the same straight line, there is no need to rotate the steel structure adjustment frame, nor is there any need to rotate the fixed steel plate 18, so the scope of application is small. To address this technical problem, the steel structure adjustment frame rotates on the outer steel plate 12 with the center of the wooden structure column 1 as the center of the circle, and then the fixed steel plate 18 rotates on the steel structure adjustment frame. According to the distribution of the wooden structure columns 1, the position of the fixed steel plate 18 is adjusted so that the fixed steel plates 18 on two adjacent wooden structure columns 1 are arranged in parallel to fix a single steel structure guardrail 30. After construction, the steel structure guardrail 30 can be on the same straight line or distributed at an angle. It is suitable for installing steel structure guardrails 30 between wooden structure columns 1 with different distributions, and has a wide range of applications. With the rotation of the steel structure adjustment frame, the guide block 28 moves in the cement mortar injection hole 24, and the threaded rod 27 moves in the guide hole 25, so that the steel structure adjustment frame rotates in a directional manner, thereby improving stability.

[0097] After step g is completed, two fixing blocks 19 are welded to the top surface of the top plate 21, and the steel structure main body 13 is set between the two fixing blocks 19. Then the steel structure main body 13 and the fixing blocks 19 are welded to increase the firmness of the connection between the steel structure adjustment frame and the outer plate 22, thereby improving the force-bearing capacity of the steel structure adjustment frame.

[0098] h. Install a single steel structure guardrail 30 between the fixing steel plates 18 on two adjacent wooden structure columns 1, and then weld the steel structure guardrail 30 and the fixing steel plates 18.

[0099] Each steel guardrail 30 is made in a factory, which can shorten the construction period and control the prefabrication quality of the steel guardrail 30. On the basis of not destroying the structure of the wooden column 1, the technical problem of firmly installing the wooden column 1 and the steel guardrail 30 is solved.

[0100] i. Painting the outer steel plate 12, and then painting the fixed steel plate 18, the steel structure guardrail 30 and the steel structure adjustment frame can protect the outer steel plate 12, the fixed steel plate 18, the steel structure guardrail 30 and the steel structure adjustment frame, while also making them aesthetically pleasing.

[0101] The color of the paint applied on the outside of the outer steel plate 12 is the same as the color of the wooden structure column 1, which improves the aesthetics.

[0102] Based on the above embodiment, a water outlet 36 is provided at the bottom of the outer plate 22. Before injecting cement mortar into the cavity 23 through the cement mortar injection hole 24, the water outlet 36 is first blocked with a plug 37. Then, clean water is poured into the cavity 23 through the cement mortar injection hole 24 for curing. The plug 37 is then removed from the water outlet 36, the clean water is drained, and the water outlet 36 is blocked again with the plug 37. Finally, cement mortar is injected into the cavity 23 through the cement mortar injection hole 24. A protrusion 38 is provided on the outer side of the plug 37 for applying force to the plug 37. Before injecting the cement mortar, the area between the outer plate 22 and the inner plate can be moistened to appropriately increase the fluidity of the cement mortar, allowing the cement mortar to quickly fill the entire cavity 23. This also allows impurities between the outer plate 22 and the inner plate to be removed, preventing the formation of holes in the cured cement mortar, which could affect its strength.

[0103] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all included in the scope of protection of the present invention.
