Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a prefabricated structural column structure constructed without formwork. Background Art

[0002] Structural columns are important secondary structural components in building masonry projects. They are mainly used to resist shear force, earthquake resistance and other lateral loads. Traditional structural columns are usually supported by wooden formwork after the wall is built. They need to go through the processes of formwork matching, supporting, fixing and dismantling. This process has the problems of long construction period, many construction processes, the overall quality of the structural columns and the quality of the construction appearance cannot be guaranteed, the input of formwork and labor is high, the economy is not high, and the consumption is high.

[0003] In view of the shortcomings of the existing technology, a prefabricated structural column structure with formwork-free construction is proposed. When the prefabricated structure is constructed without formwork, the process of supporting and removing the formwork is omitted, the process is reduced, the construction cost is reduced, and the construction efficiency is improved. Summary of the invention

[0004] In view of this, the present invention discloses a prefabricated structural column structure with formwork-free construction, which aims to save the process of supporting and removing formwork, thereby achieving the purpose of reducing the process, lowering construction costs and improving construction efficiency.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A prefabricated structural column structure for formwork-free construction comprises a prefabricated shell and masonry walls on both sides of the prefabricated shell, wherein the prefabricated shell comprises a plurality of prefabricated sections, and adjacent prefabricated sections are detachably connected; the prefabricated sections comprise symmetrically arranged main boards, which are U-shaped, and adjustment blocks are arranged between the opposite ends of the main boards, and the cross-section of the adjustment blocks is trapezoidal, and telescopic structures are arranged between the adjustment blocks, and the two ends of the telescopic structures are connected to the end faces of the adjustment blocks with large areas, and the inclined end faces of the adjustment blocks are provided with a plurality of connecting grooves, and the end faces of the main boards facing the adjustment blocks are parallel to the inclined end faces of the adjustment blocks, and a plurality of connecting sections slidably connected to the corresponding connecting grooves are fixed on the end faces of the main boards; a plurality of wall reinforcement bars are arranged on the masonry walls, and the wall reinforcement bars are detachably connected to the prefabricated sections.

[0007] In this scheme, steel bars for positioning are installed on the ground foundation, and a suitable number of prefabricated sections are selected according to the height of the structural column, and the prefabricated sections are positioned and installed between the masonry walls through the steel bars in sequence; at this time, the main boards are in a contracted state, which is convenient for being placed in the gap between the masonry walls; after the prefabricated sections are initially installed, the telescopic structure is driven, and the telescopic structure expands outward by pushing the adjustment blocks at both ends, and the inclined end faces of the adjustment blocks are used to push the main board toward the masonry wall until the main board and the masonry wall structure are connected and fixed with the wall reinforcement and the prefabricated sections; when the prefabricated sections are installed, it is only necessary to inject concrete into the prefabricated sections, and the pouring of the structural column can be completed after the concrete solidifies. There is no need to support or remove the formwork during the whole process, so as to achieve the purpose of reducing the process, reducing the construction cost and improving the construction efficiency; in addition, after the concrete solidifies, it forms a card and fixation with the inclined end faces of the adjustment blocks, which can effectively prevent the loosening between the concrete and the prefabricated shell, and extend the service life of the structural column.

[0008] Furthermore, the telescopic structure includes a cylindrical telescopic body, a vertically arranged screw rod is threadedly connected at the center of the telescopic body, a clamping block with a trapezoidal structure and a larger upper part and a smaller lower part is rotatably connected to the screw rod, a through groove is opened at the upper end of the telescopic body, and the clamping block is slidably connected in the through groove; coaxial connecting rods are slidably connected at both ends of the telescopic body, and the ends of the connecting rods are inclined and abut against the inclined surfaces of the clamping blocks; the bottom of the screw rod is threadedly connected to the top of the adjacent screw rod, and the screw rod at the bottom is fixedly connected to the ground foundation.

[0009] In this solution, the screw is rotated downward by rotating the screw in the forward direction, and the screw drives the clamping block to move downward synchronously. The clamping block pushes the connecting rods at both ends to move outward synchronously through the inclined end surface, thereby pushing the two adjustment blocks to move outward synchronously. While the screw moves downward, it is also connected with the top thread of the adjacent screw, making the connection relationship between the prefabricated sections more stable and stabilizing the screw to prevent the screw from loosening and causing the main board to shrink, affecting the casting of the structural column.

[0010] Furthermore, the main board is provided with a through hole facing the wall reinforcement, the wall reinforcement is sleeved with a mounting ring engaged with the through hole, the outer wall of the mounting ring is provided with a plurality of sliding grooves facing its axis, the sliding grooves are slidably connected with a clamping block, and an elastic reset member is provided between the clamping block and the sliding groove, the clamping block is inclined toward the side wall of the masonry wall; a connecting ring is fixed on one end of the wall reinforcement submerged in the masonry wall, and a fixing ring with an outer diameter smaller than the inner diameter of the mounting ring is slidably connected to the end of the wall reinforcement extending into the prefabricated section, a plurality of steel cables are connected between the connecting ring and the fixing ring, and the steel cables and the clamping block are staggered; a plurality of circumferentially distributed connecting grooves are provided on the inner side wall of the main board, and a coaxial hydraulic damper is fixed in the connecting groove, the output ends of the hydraulic dampers are all facing the through holes, the output ends of the hydraulic dampers are hinged with connecting rods, and the connecting rods are detachably connected to the fixing rings.

[0011] In this solution, during the installation of the prefabricated section, the connecting ring at the end of the wall reinforcement is extended into the prefabricated section through the corresponding through hole, the installation ring is inserted into the through hole, and the clamping block is pushed by the side wall of the through hole to move the clamping block toward the wall reinforcement. The wall reinforcement is clamped and fixed by the clamping block, and the connecting rod is fixedly connected to the fixing ring at the same time to complete the connection between the prefabricated section and the wall reinforcement. The whole process is simple and quick. In addition, by setting up steel cables, the deformable properties of the steel cables are utilized to improve the shear resistance of the connection between the masonry wall and the structural column, and to help reset the structural column when misaligned shear occurs between the masonry wall and the structural column; when vibration causes shear fracture of the tie wall reinforcement, the steel cables serve as a temporary connection between the masonry wall and the structural column, and the kinetic energy of the structural column is transferred to the hydraulic damper through the connecting rod for energy consumption, thereby preventing a large misalignment between the structural column and the masonry wall, which may result in the inability to reset the structural column; when the vibration amplitude is too large, causing the kinetic energy of the structural column to exceed the energy consumption range of the hydraulic damper, the connecting ring is limited by the installation ring, thereby forming a connection limit between the masonry wall and the structural column again.

[0012] Furthermore, a grouting hole connected to the connecting groove is arranged on the end surface of the adjusting block, and a supporting column parallel to the connecting groove is fixed in the connecting groove, and the supporting column runs through the connecting section.

[0013] Furthermore, vertically arranged guide grooves are provided on both sides of the through groove, and guide blocks slidably connected to the guide grooves are provided at both ends of the abutting block.

[0014] Furthermore, the steel cable, the connecting ring, the connecting rod and the hydraulic damper are treated without bonding.

[0015] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art may be taught from the practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] like Figures 1 to 5 As shown:

[0024] A prefabricated structural column structure for formwork-free construction comprises a prefabricated shell and masonry walls 1 on both sides of the prefabricated shell, wherein the prefabricated shell comprises a plurality of prefabricated sections, and adjacent prefabricated sections are detachably connected; the prefabricated sections comprise symmetrically arranged main boards 2, wherein the main boards 2 are U-shaped, and adjustment blocks 3 are arranged between the facing ends of the main boards 2, and the cross-section of the adjustment blocks 3 is trapezoidal, and a telescopic structure is arranged between the adjustment blocks 3, and the two ends of the telescopic structure are connected to the end faces of the adjustment blocks 3 with large areas, and the inclined end faces of the adjustment blocks 3 are provided with a plurality of connecting grooves 4, and the end faces of the main boards 2 facing the adjustment blocks 3 are parallel to the inclined end faces of the adjustment blocks 3, and a plurality of connecting sections 5 slidably connected to the corresponding connecting grooves 4 are fixed on the end faces of the main boards 2; a plurality of tie wall bars 6 are arranged on the masonry wall 1, and the tie wall bars 6 are detachably connected to the prefabricated sections.

[0025] In this solution, steel bars for positioning are installed on the ground foundation, and a suitable number of prefabricated sections are selected according to the height of the structural column, and the prefabricated sections are positioned and installed between the masonry walls 1 in sequence through the steel bars; at this time, the main boards 2 are in a contracted state, which is convenient for being placed in the gap between the masonry walls 1; after the prefabricated sections are initially installed, the telescopic structure is driven, and the telescopic structure expands outward by pushing the adjustment blocks 3 at both ends, and the inclined end faces of the adjustment blocks 3 are used to push the main board 2 toward the masonry wall 1 until the main board 2 and the masonry wall 1 are connected and fixed, and the tie wall bars 6 are connected and fixed to the prefabricated sections; when the prefabricated sections are installed After completion, it is only necessary to inject concrete into the prefabricated section, and the casting of the structural column can be completed after the concrete solidifies. There is no need to support and remove the formwork during the entire process, thereby achieving the purpose of reducing the number of steps, reducing construction costs, and improving construction efficiency. In addition, after the concrete solidifies, it forms a card and fixation with the inclined end face of the adjustment block 3, which can effectively prevent the loosening between the concrete and the prefabricated shell and extend the service life of the structural column. At the same time, the expansion range between the main boards 2 can be adjusted by adjusting the gap size between the adjustment blocks 3, that is, adjusting the width of the prefabricated section, thereby effectively increasing the scope of application of this patent.

[0026] In this embodiment, the telescopic structure includes a cylindrical telescopic body 7, a vertically arranged screw rod 8 is threadedly connected at the center of the telescopic body 7, a trapezoidal structure and a clamping block 9 which is larger at the top and smaller at the bottom is rotatably connected to the screw rod 8, a through groove is opened at the upper end of the telescopic body 7, and the clamping block 9 is slidably connected in the through groove; coaxial connecting rods 10 are slidably connected at both ends of the telescopic body 7, and the ends of the connecting rods 10 are inclined and abut against the inclined surfaces of the clamping block 9; the bottom of the screw rod 8 is threadedly connected to the top of the adjacent screw rod 8, and the screw rod 8 at the bottom is fixedly connected to the ground foundation.

[0027] In this solution, the screw rod 8 is rotated forward to rotate downward, and the screw rod 8 drives the clamping block 9 to move downward synchronously. The clamping block 9 pushes the connecting rods 10 at both ends to move outward synchronously through the inclined end surface, thereby pushing the two adjustment blocks 3 to move outward synchronously; and while the screw rod 8 moves downward, it is also connected with the top thread of the adjacent screw rod 8, so that the connection relationship between the prefabricated sections is more stable, and it plays a role in stabilizing the screw rod 8, preventing the screw rod 8 from loosening and causing the main board 2 to retract, affecting the casting of the structural column.

[0028] In this embodiment, the main board 2 is provided with a through hole facing the wall reinforcement 6, and the wall reinforcement 6 is sleeved with a mounting ring 11 that is engaged with the through hole. The outer wall of the mounting ring 11 is provided with a plurality of slide grooves toward its axis, and the slide grooves are slidably connected with a clamping block 12, and an elastic reset member is provided between the clamping block 12 and the slide groove, and the clamping block 12 is inclined toward the side wall of the masonry wall 1; a connecting ring 14 is fixed on one end of the wall reinforcement 6 that is not in the masonry wall 1, and the wall reinforcement 6 extends into one end of the prefabricated section. A fixing ring 13 with an outer diameter smaller than the inner diameter of the mounting ring 11 is slidably connected to the end, and a plurality of steel cables 15 are connected between the connecting ring 14 and the fixing ring 13, and the steel cables 15 and the pressing blocks 12 are staggered. A plurality of circumferentially distributed connecting grooves 4 are provided on the inner side wall of the main board 2, and a coaxial hydraulic damper 16 is fixed in the connecting groove 4, and the output ends of the hydraulic dampers 16 are all facing the through holes, and the output ends of the hydraulic dampers 16 are all hinged with connecting rods 17, and the connecting rods 17 are detachably connected to the fixing ring 13.

[0029] In this solution, during the installation of the prefabricated section, the connecting ring 14 at the end of the wall reinforcement 6 is extended into the prefabricated section through the corresponding through hole, the installation ring 11 is inserted into the through hole, and the clamping block 12 is pushed by the side wall of the through hole to move the clamping block 12 toward the wall reinforcement 6. The wall reinforcement 6 is clamped and fixed by the clamping block 12, and the connecting rod 17 is fixedly connected to the fixing ring 13 at the same time to complete the connection between the prefabricated section and the wall reinforcement 6. The whole process is simple and quick. In addition, by arranging the steel cable 15, the deformable property of the steel cable 15 is utilized to improve the shear resistance of the connection between the masonry wall 1 and the structural column, and to help the structural column to be reset when the masonry wall 1 and the structural column are dislocated and sheared; when the vibration causes the tie bar 6 to shear and break, the steel cable 15 serves as a temporary connection between the masonry wall 1 and the structural column, and the kinetic energy of the structural column is transferred to the hydraulic damper 16 through the connecting rod 10 for energy consumption, to prevent the structural column from being unable to be reset due to a large dislocation between the structural column and the masonry wall 1; when the vibration amplitude is too large and the kinetic energy of the structural column exceeds the energy consumption range of the hydraulic damper 16, the connecting ring 11 is used to limit the connecting ring 14, and the connection limit between the masonry wall 1 and the structural column is formed again.

[0030] In this embodiment, a grouting hole 18 connected to the connecting groove 4 is provided on the end face of the adjusting block 3, and a support column 19 parallel to the connecting groove 4 is fixed in the connecting groove 4, and the support column 19 passes through the connecting section 5; through the cooperation between the support column 19 and the connecting section 5, a guiding role is played for the relative movement between the main board 2 and the adjusting block 3; when casting the structural column, concrete is poured into the connecting groove 4 through the grouting hole 18 to fix the connecting section 5, that is, to fix the positional relationship between the main board 2 and the adjusting block 3.

[0031] In this embodiment, vertical guide grooves are provided on both sides of the through groove, and guide blocks (not shown in the figure) slidably connected to the guide grooves are provided at both ends of the clamping block 9; the movement of the clamping block 9 is guided by the cooperation between the guide block and the guide groove.

[0032] In this embodiment, the steel cable 15, the connecting ring 14, the connecting rod 17 and the hydraulic damper 16 are treated without bonding to prevent the above structures from being fixed by concrete and failing to play a corresponding role.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
