Description

Technical Field

[0001] This invention belongs to the field of prefabricated component installation technology, specifically relating to a steel reinforcement connection structure for prefabricated assembled components and its construction method. Background Technology

[0002] Precast components refer to steel, wood, or concrete components that are prefabricated in a factory or on-site according to design specifications. Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated buildings mainly include precast prefabricated concrete structures, steel structures, and modern wood structures. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they represent modern industrialized production methods.

[0003] Precast components can greatly shorten the construction period and provide a certain level of construction efficiency for temporary sites. Existing precast components are generally assembled after prefabrication, and steel structures and concrete structures are usually installed and assembled separately with relatively weak connections. The construction methods cannot be adjusted according to the actual situation, resulting in inconvenience in use. Based on this, we propose a steel reinforcement connection structure for precast components and its construction method. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a steel reinforcement connection structure for prefabricated components and its construction method, which solves the problems that existing prefabricated components, steel structures and concrete structures are usually installed and assembled separately, resulting in relatively weak connections and the inability to adjust construction methods according to actual conditions.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel reinforcement connection structure for prefabricated components, comprising a support column and a support plate. The top and bottom ends of the support column are provided with butt grooves. A first crossbar is inserted into the inside of the butt groove, and a second crossbar is inserted into the inside of the butt groove. Fixing plates are fixedly sleeved on the outer sides of both ends of the first and second crossbars. Baffles are installed on the front and back of the first and second crossbars. Several steel reinforcement holes are provided inside the first and second crossbars. Several fastening bolts are inserted into the top and bottom ends of the support column. A base plate is fixedly installed at the top and bottom of the support column. The first crossbar... Three insulation boards are movably installed on the opposite side of the crossbar 2. Two sets of sliding strips are movably installed on the opposite side of the three insulation boards. Four L-plates are movably installed on the outer side of the three insulation boards. Several steel bar holes 2 are opened inside both ends of the crossbar 1 and crossbar 2. Several steel bar holes 3 are opened inside the support plate. Several installation holes 1 and 4 are opened inside both ends of the support plate. The bottom of the steel bar holes 3 is connected to a connecting cylinder. Casting holes are opened at both ends of the support plate. A base column is fixedly installed at the bottom of the support plate. Several inclined plates are fixedly installed at the bottom of the connecting cylinder.

[0006] Preferably, the fixing plate is fixedly installed on the opposite side of the support column by bolts, and the second crossbar and the first crossbar are symmetrically and evenly distributed on the opposite side of the support column.

[0007] By adopting the above technical solution, the advantage is that the function of the fixing plate is to fix the crossbar one and crossbar two to the corresponding positions on the opposite sides of the support column, which facilitates stable positioning and easy assembly and use.

[0008] Preferably, the connecting cylinder is fixedly installed at the bottom of the support plate, and a reinforcing rod is fixedly installed inside the connecting cylinder. The casting hole and the reinforcing bar hole are both located on the inner side of the base column.

[0009] By adopting the above technical solution, the advantage is that it facilitates the stabilization of structural forces and increases the strength and stability under stress.

[0010] Preferably, the baffle is fixed to the outside of the first and second crossbars by bolts, and both ends of the baffle are provided with slots that are compatible with the fixing plate and the base plate.

[0011] The advantages of adopting the above technical solution are that it is easy to select according to the actual construction situation, easy to limit the installation and use position, and the overall structure is stable.

[0012] Preferably, the first reinforcing bar hole is arranged linearly and uniformly inside the first and second crossbars, the position of the first reinforcing bar hole corresponds to the position of the sliding bar, and the specifications and dimensions of the first reinforcing bar hole are adapted to the specifications and dimensions of the third reinforcing bar hole.

[0013] By adopting the above technical solution, the advantage is that it is easy to increase the internal structural stress and increase the overall structural stability.

[0014] Preferably, the base plate has a plurality of mounting holes inside, and the mounting holes are rectangular and evenly distributed inside the support plate and the base plate, respectively. The size of the mounting holes is compatible with the size of the mounting holes.

[0015] By adopting the above technical solution, the advantages are that the bolts are fixed to the top of the support plate, which facilitates assembly and fixing, stabilizes the structural force, and facilitates splicing operations.

[0016] Preferably, the two sets of sliding strips are symmetrically fixedly installed on opposite sides of the support column, the outer sides of the three insulation boards are provided with sealing strips, and the four L-plates are fixedly installed on opposite sides of the support column by bolts.

[0017] By adopting the above technical solution, the advantage lies in the overall structural stability, which makes it easier to increase the overall structural stress and stabilize the structure.

[0018] Preferably, the second reinforcing bar hole is rectangular and evenly distributed at both ends of the first and second crossbars, and the size of the fourth reinforcing bar hole is compatible with the size of the second reinforcing bar hole.

[0019] By adopting the above technical solution, the advantage is that the reinforcing bar penetrates through the second reinforcing bar hole and enters the interior of the fourth reinforcing bar hole, which facilitates the addition of a force inside and helps stabilize the structure.

[0020] Preferably, the fastening bolts are movably inserted through the support column, crossbar one and crossbar two and extend to the outside of the support column, and the bolts and corresponding holes are provided with threads.

[0021] By adopting the above technical solution, the advantages are that the construction is convenient and quick, it is easy to reduce the weight of the structure, stabilize the internal torque, and the overall use effect is good and easy to stabilize.

[0022] A construction method for a steel reinforcement connection structure of prefabricated components includes the following steps:

[0023] S1: There are two construction methods during construction. First, at the site where construction is required, multiple foundations corresponding to the support plates are pre-set according to the drawings. Pit holes are dug at the positions corresponding to the base columns and inclined plates. Before placing the base columns and inclined plates into the pits, concrete is filled into the pits. Then, the base columns and inclined plates are placed inside the concrete, and the support plates are level with the ground. After the positions of the support plates, inclined plates, and base columns are stabilized, the support columns are placed on top of the support plates through the corresponding base plates and fixed with bolts through the mounting holes one and the mounting holes inside the base plates. Then, the crossbars one and two are inserted into the inside of the connecting grooves, and the ends of multiple crossbars one and two are inserted into the corresponding connecting grooves, so that the crossbars one and two of the two sets of support columns correspond to each other through the connecting grooves inside the support columns, and the rebar holes two are distributed in a rectangular shape inside the support columns. Then, the fixing plates are fixed to the opposite sides of the support columns with bolts, which indirectly fixes the positions of crossbars one and two. At this time, the basic structure splicing is completed.

[0024] S2: Before splicing, place the corresponding insulation board on the opposite side of the sliding strip. After splicing, fix the insulation board to the corresponding position of the support column using the L-plate. Then, install the baffle that matches the fixing plate, crossbar one, bottom plate, and crossbar two in the appropriate corresponding position. After the general shape is assembled, fill the corresponding position with concrete. The concrete fills the top of the support column and crossbar one. The concrete flows into the support column through the space between the support column and crossbar one. Then, the concrete vibrator passes the vibrator through the preset space to process the concrete inside the support column. While filling the concrete, the concrete is limited by the corresponding baffle and crossbar one, and guided by the action of the rebar hole one. The concrete flows into the interior of crossbar one, insulation board, and sliding strip, and finally flows into the interior of the bottom baffle through crossbar two. As filling proceeds, the vibrator will vibrate and guide the fine concrete to improve the flow speed and filling efficiency, and to increase the internal structural strength.

[0025] S3: After the concrete is filled and before it hardens, insert steel bars of a size smaller than those in steel bar holes 2 and 1 into steel bar holes 2 and 1. At this time, the steel bar inserted into steel bar hole 2 is vertically downward, so that the steel bar is inserted into steel bar hole 4. When the steel bar is inserted into the interior, during the process of filling the column, since the bottom of the column is open, the concrete enters the interior of the foundation column through the bottom opening of the column, through steel bar hole 4 and the pouring hole. The steel bar and concrete mix inside the foundation column. When the steel bar inserted into steel bar hole 1 is vertically downward, the steel bar passes through crossbar 1 and crossbar 2 and enters the interior of steel bar hole 3. Then, through the interior of the connecting cylinder, the external wall vibration is conducted before the concrete hardens, so that the steel bar and concrete are evenly distributed.

[0026] S4: After the concrete construction is completed, the concrete construction can also be carried out by assembling the structure, inserting the reinforcing bars into the corresponding positions, tying the reinforcing bars accordingly, hoisting the assembled whole, and then pouring concrete. This can sacrifice the convenience of construction in order to increase the overall structural strength. The concrete construction operation is suitable for semi-permanent building construction, which is conducive to stabilizing the structural force and increasing the stress strength and stability.

[0027] S5: Another construction method corresponding to concrete construction. In this case, the assembly and foundation fixing are the same as in the above steps. The difference is that when the base column is installed into the pre-set pit, the foundation concrete is poured into the interior of the base column through the pouring hole to stabilize the bottom of the base column and the support plate. The concrete pouring step is eliminated. Long bolts are inserted into the rebar holes 2, 1, 3, 4 and the corresponding positions. The size of the long bolts is compatible with the rebar holes 2, 1, 3, 4 and the connecting cylinder. During the insertion process, it is necessary to rotate the bolts because the inner side of the rebar holes 2, 1, 3, 4 and the connecting cylinder are all provided with threads corresponding to the long bolts. The long bolts connect multiple structures, and the holes for multiple bolt connections make the connection of each structure stable. After the connection is completed, the head of the long bolt is welded and fixed. This construction method is suitable for temporary sites, and the construction is convenient and quick. It helps to reduce the weight of the structure, stabilize the internal torque, and has a good overall performance.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. After the concrete is filled and before it hardens, insert a steel bar with a size smaller than that of Rebar Hole 2 and Rebar Hole 1 into Rebar Hole 2 and Rebar Hole 1 through the set rebar hole 2. At this time, the steel bar inserted into Rebar Hole 2 is vertically downward, so that the steel bar is inserted into Rebar Hole 4. When it is inserted into the interior, during the process of filling the column, since the bottom of the column is open, the concrete enters the interior of the foundation column through the bottom opening of the column, through Rebar Hole 4 and the pouring hole. The steel bar and concrete mix inside the foundation column. When the steel bar inserted into Rebar Hole 1 is vertically downward, the steel bar passes through Crossbar 1 and Crossbar 2 and enters the interior of Rebar Hole 3. Then, through the interior of the connecting cylinder, the external wall vibration is conducted before the concrete hardens, so that the steel bar and concrete are evenly distributed.

[0030] 2. Through the set concrete construction steps, after the concrete construction is completed, the concrete construction can also be carried out by assembling the structure, inserting the steel bars into the corresponding positions, and tying the steel bars accordingly. After the overall assembly is hoisted and assembled, concrete can be poured in. This can sacrifice the convenience of construction to increase the overall structural strength. The concrete construction operation is suitable for semi-permanent building construction, which is conducive to stabilizing the structural force and increasing the stress strength and stability.

[0031] 3. Another construction method for concrete construction using the set base columns is as follows: the assembly and foundation fixing are the same as in the above steps. The difference is that when the base columns are installed into the pre-set pits, the foundation concrete is poured into the interior of the base columns through the pouring holes to stabilize the bottom of the base columns and support plates. The concrete pouring step is eliminated. Long bolts are inserted into the corresponding positions of rebar holes 2, 1, 3, 4 and the connecting cylinder. The size of the long bolts is compatible with rebar holes 2, 1, 3, 4 and the connecting cylinder. During insertion, rotation is required because the inner sides of rebar holes 2, 1, 3, 4 and the connecting cylinder are provided with threads corresponding to the long bolts. The long bolts connect multiple structures, and the holes for multiple bolt connections ensure stable connection of each structure. After the connection is completed, the head of the long bolt is welded for fixation. This construction method is suitable for temporary sites, and the construction is convenient and quick. It helps to reduce the weight of the structure, stabilizes the internal torque, and has a good overall performance and is easy to stabilize. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1-5 As shown, a steel reinforcement connection structure for a prefabricated assembly includes a support column 1 and a support plate 14. The top and bottom ends of the support column 1 are provided with butt joint grooves 12. A first crossbar 4 and a second crossbar 10 are inserted into the butt joint grooves 12. Fixing plates 6 are fixedly sleeved on the outer sides of both ends of the first crossbar 4 and the second crossbar 10. Baffles 11 are installed on the front and back of the first crossbar 4 and the second crossbar 10. Several steel reinforcement holes 3 are provided inside the first crossbar 4 and the second crossbar 10. Several fastening bolts 2 are inserted into the top and bottom ends of the support column 1. A base plate 9 is fixedly installed on the top and bottom of the support column 1. The opposite sides of the first crossbar 4 and the second crossbar 10 are movable. Three insulation boards 7 are installed. Two sets of sliding strips 13 are movably installed on opposite sides of the three insulation boards 7. Four L-plates 8 are movably installed on the outer side of the three insulation boards 7. Several steel bar holes 2 5 are opened inside both ends of the crossbar 1 4 and crossbar 2 10. Several steel bar holes 3 15 are opened inside the support plate 14. Several installation holes 1 18 are opened inside both ends of the support plate 14. Several steel bar holes 4 17 are opened inside both ends of the support plate 14. The bottom of the steel bar holes 3 15 is connected to the connecting cylinder 21. The two ends of the support plate 14 are opened with pouring holes 16. The bottom of the support plate 14 is fixedly installed with a base column 20. Several inclined plates 19 are fixedly installed at the bottom of the connecting cylinder 21.

[0040] The working principle of the above technical solution is as follows:

[0041] During construction, firstly, at the site where work is to be carried out, foundations corresponding to multiple support plates 14 are pre-set according to the drawings. Pit holes are dug at positions corresponding to the base columns 20 and inclined plates 19. Before placing the base columns 20 and inclined plates 19 into the pits, concrete is filled into the pits. Then, the base columns 20 and inclined plates 19 are placed inside the concrete, and the support plates 14 are level with the ground. After the positions of the support plates 14, inclined plates 19, and base columns 20 are stabilized, the support column 1 is placed on top of the support plate 14 through the corresponding base plate 9 and fixed with bolts through the mounting holes 18 and the mounting holes inside the base plate 9. Next, the crossbars 1-4 and 2-10 are inserted into the connecting grooves 12, and the ends of the multiple crossbars 1-4 and 2-10 are respectively inserted into the corresponding connecting grooves 12, so that... The two sets of support columns 1 have their crossbars 4 and 10 connected inside the support column 1 via a butt joint 12, resulting in a rectangular distribution of the rebar holes 5 inside the support column 1. Then, the fixing plate 6 is bolted to the opposite side of the support column 1, indirectly fixing the positions of crossbars 4 and 10. This completes the basic structure assembly. Before assembly, the corresponding insulation board 7 is placed on the opposite side of the sliding strip 13. After assembly, the insulation board 7 is fixed to the corresponding position of the support column 1 using the L-plate 8. Next, the baffle 11, which matches the fixing plate 6, crossbar 4, base plate 9, and crossbar 10, is installed in the appropriate corresponding position. Once the approximate shape is assembled, concrete is filled into the corresponding positions, filling the support column 1 and crossbar 4. At the top of column 4, concrete flows into and fills the interior of column 1 through the space between column 1 and crossbar 4 and crossbar 10. Then, a concrete vibrator passes the vibrator through a pre-set space to process the concrete inside column 1. During filling, the concrete is limited by the corresponding baffle 11 and crossbar 4, and guided by the rebar hole 3. The concrete flows into the interior of crossbar 4, insulation board 7, and sliding strip 13, and finally flows into the bottom baffle 11 through crossbar 10. As filling progresses, the vibrator vibrates and guides the fine concrete, improving the flow rate and filling efficiency, and increasing the internal structural strength. After the concrete filling is complete, and before the concrete hardens, a section with a corresponding dimension smaller than... The reinforcing bars in Reinforcing Bar Hole 25 and Reinforcing Bar Hole 13 are inserted into Reinforcing Bar Hole 25 and Reinforcing Bar Hole 13 respectively. At this time, the reinforcing bar inserted into Reinforcing Bar Hole 25 is vertically downward, so that the reinforcing bar is inserted into Reinforcing Bar Hole 47. During the process of filling the support column 1, since the bottom of the support column 1 is open, the concrete enters the base column 20 through the bottom opening of the support column 1, through Reinforcing Bar Hole 47 and the pouring hole 16. The reinforcing bar and concrete are mixed inside the base column 20. When the reinforcing bar inserted into Reinforcing Bar Hole 13 is vertically downward, the reinforcing bar passes through Crossbar 14 and Crossbar 20 and enters the interior of Reinforcing Bar Hole 35. Then, it passes through the interior of the connecting cylinder 21. Before the concrete solidifies, the external wall vibration is conducted to distribute the reinforcing bar and concrete evenly.

[0042] In another implementation scheme, such as Figures 1-5 As shown, the fixing plate 6 is fixedly installed on the opposite side of the support column 1 by bolts, and the crossbar 10 and the crossbar 4 are symmetrically and evenly distributed on the opposite side of the support column 1.

[0043] The function of the fixing plate 6 is to fix the crossbar 1 4 and crossbar 2 10 to the corresponding positions on opposite sides of the support column 1, so as to stabilize the position and facilitate assembly and use.

[0044] In another implementation scheme, such as Figures 1-5 As shown, the connecting cylinder 21 is fixedly installed at the bottom of the support plate 14, and a reinforcing rod is fixedly installed inside the connecting cylinder 21. The pouring hole 16 and the reinforcing bar hole 17 are both located inside the base column 20.

[0045] After the concrete construction is completed, the concrete construction can also be carried out by assembling the structure, inserting the reinforcing bars into the corresponding positions, tying the reinforcing bars accordingly, hoisting the assembled whole, and then pouring concrete. This can sacrifice the convenience of construction in order to increase the overall structural strength. The concrete construction operation is suitable for semi-permanent building construction, which is conducive to stabilizing the structural force and increasing the stress strength and stability.

[0046] In another implementation scheme, such as Figures 1-5 As shown, the baffle 11 is fixed to the outside of the first crossbar 4 and the second crossbar 10 by bolts. Both ends of the baffle 11 are provided with slots that are compatible with the fixing plate 6 and the base plate 9.

[0047] The baffle 11 provides a position for the concrete or foam, which facilitates structural stability, allows for selection based on actual construction conditions, and helps limit the installation and use position, thus ensuring overall structural stability.

[0048] In another implementation scheme, such as Figures 1-5 As shown, the reinforcing bar holes 1-3 are arranged linearly and evenly inside the crossbar 1-4 and crossbar 2-10. The position of the reinforcing bar holes 1-3 corresponds to the position of the sliding bar 13. The specifications and dimensions of the reinforcing bar holes 1-3 are compatible with the specifications and dimensions of the reinforcing bar holes 3-15.

[0049] The insertion of reinforcing bars into the first reinforcing bar hole 3 facilitates the passage of reinforcing bars through the corresponding positions of the first crossbar 4, the second crossbar 10, the sliding bar 13, and the third reinforcing bar hole 15, thereby increasing the internal structural stress and enhancing the overall structural stability.

[0050] In another implementation scheme, such as Figures 1-5 As shown, the base plate 9 has several mounting holes inside. Mounting hole 18 and mounting hole 18 are evenly distributed in a rectangular shape inside the support plate 14 and the base plate 9, respectively. The size of the mounting holes is compatible with the size of mounting hole 18.

[0051] It is convenient to fix the support column 1 to the top of the support plate 14 through the base plate 9, the mounting hole 18 and the bolts, which facilitates assembly and fixing, stabilizes the structural force and facilitates splicing operations.

[0052] In another implementation scheme, such as Figures 1-5 As shown, two sets of sliding strips 13 are symmetrically fixed on opposite sides of the support column 1, and sealing strips are provided on the outer sides of the three insulation boards 7. The four L-plates 8 are fixed on opposite sides of the support column 1 by bolts.

[0053] The insulation board 7 serves the function of insulation and wall insulation. It is easy to reserve holes under the limit of the slide bar 13, which facilitates operation. The overall structure is stable, which can increase the overall structural strength and make it more stable.

[0054] In another implementation scheme, such as Figures 1-5 As shown, the second reinforcing bar hole 5 is evenly distributed in a rectangular shape at both ends of the first horizontal bar 4 and the second horizontal bar 10, and the size of the fourth reinforcing bar hole 17 is compatible with the size of the second reinforcing bar hole 5.

[0055] The function of the second reinforcing bar hole 5 is the same as that of the first reinforcing bar hole 3, which helps to stabilize the position of the first crossbar 4 and the second crossbar 10, and allows the reinforcing bar to pass through the second reinforcing bar hole 5 and enter the interior of the fourth reinforcing bar hole 17, which adds a force to the interior and helps to stabilize the structure.

[0056] In another implementation scheme, such as Figures 1-5 As shown, the fastening bolt 2 moves through the support column 1, the first crossbar 4 and the second crossbar 10 and extends to the outside of the support column 1. The bolt and the corresponding position of the hole are all provided with threads.

[0057] In the corresponding concrete construction method, the assembly and foundation fixing are the same as in the above steps. The difference is that when the base column 20 is installed into the pre-set pit, the foundation concrete is poured into the interior of the base column 20 through the pouring hole 16 to stabilize the bottom of the base column 20 and the support plate 14. The concrete pouring step is eliminated, and long bolts are inserted into the rebar holes 2.5, 1.3 and corresponding positions. The size of the long bolts is compatible with the rebar holes 2.5, 1.3, 3.15, 4.17 and the connecting cylinder 21. Furthermore, during the insertion process, rotation is required because the inner sides of the rebar hole 25, rebar hole 13, rebar hole 315, rebar hole 417, and connecting cylinder 21 are all equipped with threads corresponding to long bolts. These long bolts connect multiple structures, and due to the setting of holes for multiple bolt connections, the connection of each structure is stable. After the through connection, the head of the long bolt is welded and fixed. This construction method is suitable for temporary sites, and the construction is convenient and relatively quick. It helps to reduce the weight of the structure, stabilizes the internal torque, and has a good overall effect and is easy to stabilize.

[0058] A construction method for a steel reinforcement connection structure of prefabricated components includes the following steps:

[0059] S1: There are two construction methods during construction. First, at the site where construction is required, multiple foundations corresponding to the support plates 14 are pre-set according to the drawings. Pit holes are dug at positions corresponding to the base columns 20 and inclined plates 19. Before placing the base columns 20 and inclined plates 19 into the pits, concrete is filled into the pits. Then, the base columns 20 and inclined plates 19 are placed inside the concrete, and the support plates 14 are level with the ground. After the positions of the support plates 14, inclined plates 19, and base columns 20 are stabilized, the support column 1 is placed on top of the support plates 14 through the corresponding base plate 9, and installed through the mounting hole 1. The mounting holes inside the base plate 9 and 18 are fixed with bolts. Then, the first crossbar 4 and the second crossbar 10 are inserted into the inside of the mating groove 12. The two ends of the first crossbar 4 and the second crossbar 10 are respectively inserted into the corresponding mating groove 12, so that the first crossbar 4 and the second crossbar 10 of the two sets of support columns 1 correspond to each other through the mating groove 12 inside the support column 1, and the second rebar hole 5 is distributed in a rectangular shape inside the support column 1. Then, the fixing plate 6 is fixed to the opposite side of the support column 1 with bolts, which indirectly fixes the position of the first crossbar 4 and the second crossbar 10. At this time, the splicing of the foundation structure is completed.

[0060] S2: Before the splicing is completed, place the corresponding insulation board 7 on the opposite side of the sliding strip 13. After the splicing is completed, fix the insulation board 7 to the corresponding position of the support column 1 using the L plate 8. Then, install the baffle 11, which matches the fixing plate 6, crossbar 4, base plate 9, and crossbar 10, in the appropriate corresponding position. After the general shape is assembled, fill the corresponding position with concrete. The concrete fills the top of the support column 1 and crossbar 4. The concrete flows into the support column 1 through the space between the crossbar 4 and crossbar 10 and the support column 1. Then, a concrete vibrator is used to pass the vibrator through a preset space to process the concrete inside the support column 1. While filling the concrete, the concrete is limited by the corresponding baffle 11 and crossbar 4, and guided by the action of the rebar hole 3. The concrete flows into the interior of the crossbar 4, insulation board 7 and sliding strip 13, and finally flows into the bottom baffle 11 through the crossbar 2 10. As the filling is carried out, the vibrator will vibrate and guide the fine concrete to improve the flow rate and filling efficiency, and to increase the internal structural strength.

[0061] S3: After the concrete is filled and before it hardens, insert steel bars with dimensions smaller than those in steel bar hole 25 and steel bar hole 13 into the interior of steel bar hole 25 and steel bar hole 13. At this time, the steel bar inserted into steel bar hole 25 is vertically downward, so that the steel bar is inserted into the interior of steel bar hole 47. When the steel bar is inserted, during the process of filling the support column 1, since the bottom of the support column 1 is open, the concrete enters the interior of the base column 20 through the bottom opening of the support column 1, steel bar hole 47 and pouring hole 16. The steel bar and concrete mix inside the base column 20. When the steel bar inserted into steel bar hole 13 is vertically downward, the steel bar passes through crossbar 14 and crossbar 20 and enters the interior of steel bar hole 35. Then, through the interior of the connecting cylinder 21, the external wall vibration is conducted before the concrete hardens, so that the steel bar and concrete are evenly distributed.

[0062] S4: After the concrete construction is completed, the concrete construction can also be carried out by assembling the structure, inserting the reinforcing bars into the corresponding positions, tying the reinforcing bars accordingly, hoisting the assembled whole, and then pouring concrete. This can sacrifice the convenience of construction in order to increase the overall structural strength. The concrete construction operation is suitable for semi-permanent building construction, which is conducive to stabilizing the structural force and increasing the stress strength and stability.

[0063] S5: Another construction method corresponding to concrete construction. In this case, the assembly and foundation fixing are the same as in the above steps. The difference is that when the base column 20 is installed into the pre-set pit, the foundation concrete is poured into the interior of the base column 20 through the pouring hole 16 to stabilize the bottom of the base column 20 and the support plate 14. The concrete pouring step is cancelled. Long bolts are inserted into the rebar holes 2.5, 1.3 and corresponding positions. The size of the long bolts is the same as that of the rebar holes 2.5, 1.3, 1.5, 1.7 and 2.1. The device is compatible and requires rotation during insertion because the inner sides of the rebar hole 25, rebar hole 13, rebar hole 315, rebar hole 417, and connecting cylinder 21 are all equipped with threads corresponding to long bolts. These long bolts connect multiple structures, and the holes for connecting multiple bolts ensure stable connection of each structure. After the through connection, the head of the long bolt is welded and fixed. This construction method is suitable for temporary sites, and the construction is convenient and quick. It helps to reduce the weight of the structure, stabilizes the internal torque, and has a good overall effect and is easy to stabilize.
