Description

Technical Field

[0001] The present invention relates to the technical field of special-shaped hyperbolic surface construction, and in particular to a special-shaped hyperbolic surface formwork support mechanism, a system thereof, and a construction method thereof. Background Art

[0002] Modern architectural design is becoming increasingly diverse. Special-shaped hyperbolic panels, due to their unique shape and functionality, are widely used in iconic structures such as stadiums, theaters, museums, and super-high-rise buildings. These panels not only meet aesthetic requirements but also achieve complex structural functions, making them popular among designers.

[0003] However, in the actual concrete pouring process, due to the complex spatial structure of the special-shaped hyperbolic panels and the difficulty in controlling the shape accuracy, the construction is extremely difficult. At present, regarding the construction of special-shaped hyperbolic surfaces, if pre-made steel formwork is used for construction, when there are multiple special-shaped structures in a construction project, the use of pre-made steel formwork will cause material waste due to its fixed shape and cannot be reused, which reduces the turnover of materials and significantly increases construction costs. When wooden formwork is used for direct splicing, it is necessary to cut the wooden formwork into small pieces and then splice them together to meet the construction requirements with precision. At the same time, due to the use of a large number of small formworks for splicing, the number of template intersections is large, there is a risk of concrete leakage during construction, and the curved surface formed is not necessarily a smooth surface, requiring manual repair later. Therefore, this method seriously increases construction costs and workload.

[0004] Therefore, there is an urgent need to provide a special-shaped hyperbolic formwork support system and a construction method thereof to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a special-shaped hyperbolic formwork support system and a construction method thereof.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A special-shaped hyperbolic formwork support mechanism, comprising a special-shaped hyperbolic formwork support mechanism arranged between a wall and a concrete floor pad, the special-shaped hyperbolic formwork support mechanism comprising a formwork, a plurality of first wooden strips, a plurality of second wooden strips, a steel pipe bracket and a plurality of fasteners, the steel pipe bracket being fixedly constructed by a plurality of steel pipes and a plurality of fasteners as a bottom support, the first wooden strips being short wooden strips, the second wooden strips being long wooden strips, a plurality of top horizontal supporting steel pipes being fixed to the top of the steel pipe bracket via fasteners, the plurality of first wooden strips being respectively arranged between two top horizontal supporting steel pipes, an adjacent intersection of the first wooden strips being located between the two top horizontal supporting steel pipes, the first wooden strips and the steel pipe bracket each having an overlap angle, the overlap angle between the first wooden strips and the steel pipe bracket changing irregularly between the two top horizontal supporting steel pipes;

[0008] The second row of wooden beams is fixed on top of the first row of wooden beams in a flat manner, and the template is fixed on top of the second row of wooden beams.

[0009] Furthermore, the top horizontal supporting steel pipe is fixedly connected using two fasteners, and the first wooden square and the top horizontal supporting steel pipe are fixed using iron wire.

[0010] Furthermore, the second row of wooden beams is fixed to the first row of wooden beams in equal proportions between the two non-parallel top horizontal supporting steel pipes.

[0011] Furthermore, the second wooden square is fixed to the first wooden square by using iron nails, the template is fixed to the second wooden square by using iron nails, and the template and the second wooden square are fitted together to form a special-shaped hyperbolic shape.

[0012] Furthermore, the thickness of the template is 10 mm and a large template is used to splice the special-shaped hyperbolic panel. The first wooden squares at the adjacent intersections have an overlapped portion of 100 mm.

[0013] The present invention also proposes a support system for a special-shaped hyperbolic formwork mechanism, which is used to construct a support mechanism for a special-shaped hyperbolic formwork, including original special-shaped hyperbolic surface contour lines and optimized contour lines. The optimized contour lines are formed by optimizing the original special-shaped hyperbolic surface contour lines of the special-shaped hyperbolic surface three-dimensional model by replacing straight lines with curves. The steel pipe support is arranged by calculation based on the optimized contour lines, and also includes supplementary contour lines, bracket middle elevation control points, bracket edge elevation control points and special-shaped hyperbolic surface edge elevation control points. The bracket middle elevation control points, bracket edge elevation control points and special-shaped hyperbolic surface edge elevation control points are used to control the elevation of the formwork at the control points. The supplementary contour lines are used to provide a fixed position for the first wooden square to reduce its cantilever length. The on-site elevations of the bracket middle elevation control points, bracket edge elevation control points and special-shaped hyperbolic surface edge elevation control points are used to establish a comparison between the on-site model and the design model and to combine the model with other professional models.

[0014] Furthermore, the original contour lines of the irregular hyperbolic surface are extracted from the irregular hyperbolic surface three-dimensional model in the form of equal elevation difference. When extracting the original contour lines of the irregular hyperbolic surface, the horizontal distance between the contour lines should be within the arrangement distance of the steel pipe support.

[0015] Furthermore, the shape of the original contour line of the special-shaped hyperboloid is slightly curved, the optimized contour lines are non-parallel, and the top horizontal supporting steel pipe is arranged along the direction of the optimized contour lines.

[0016] Furthermore, the maximum deviation between the on-site elevation and theoretical elevation of the middle elevation control point of the bracket, the edge elevation control point of the bracket and the edge elevation control point of the special-shaped hyperbolic surface is 10 mm. When the elevation difference between the middle elevation control point of the bracket and the edge elevation control point of the bracket exceeds 10 mm, the top horizontal support steel pipe is bent at the middle elevation control point of the bracket to form a V-shaped horizontal support steel pipe to meet the elevation requirements. When the elevation difference between the middle elevation control point of the bracket and the edge elevation control point of the bracket does not exceed 10 mm, the top horizontal support steel pipe is a straight horizontal support steel pipe. The second wooden square is divided into left and right parts when the top horizontal support steel pipe is a V-shaped horizontal support steel pipe. When the top horizontal support steel pipe is a straight horizontal support steel pipe, the second wooden square is used as the contour line between the optimized contour lines.

[0017] The present invention also provides a construction method for a special-shaped hyperbolic formwork support system, which is used to construct the special-shaped hyperbolic formwork support system, comprising the following steps:

[0018] S1: Create or obtain a three-dimensional model of a special-shaped hyperbolic surface;

[0019] S2: extracting contour lines of three-dimensional model, extracting contour lines in the form of equal height difference, and the extracted contour lines need to be projected on a plane, or contour lines can be extracted according to different height differences, and the interval between two contour lines on the plane should be ensured to be not greater than the calculated interval of the steel pipe support;

[0020] S3: optimizing contour lines according to partition, partitioning according to the plate beam characteristics of the special hyperboloid, and respectively optimizing the original special hyperboloid contour lines in the form of replacing curves with straight lines to form optimized contour lines;

[0021] S4: arranging steel pipe vertical rods along the direction of the optimized contour lines according to the calculated interval requirements;

[0022] S5: setting control points along the optimized contour lines, and the control points should include middle elevation control points of the support, edge elevation control points of the support and edge elevation control points of the special hyperboloid;

[0023] S6: arranging vertical rod positions on site according to the drawings;

[0024] S7: erecting the steel pipe support;

[0025] S8: laying the first wooden square;

[0026] S9: laying the second wooden square;

[0027] S10: pre-laying the formwork and measuring the elevation of the control points;

[0028] S11: adjusting the elevation of the control points;

[0029] S12: laying the formwork on the large surface;

[0030] S13: re-measuring the elevation of the control points;

[0031] S14: comparing the on-site model with the design model.

[0032] Compared with the prior art, the present application has the following beneficial effects:

[0033] 1. The present application selects appropriate contour lines with height difference for linear optimization, sets up support vertical rods on the linear contour lines, sets up curve bottom elevation control points at both sides and in the middle of the same contour line after optimization and along the curve boundary extended from the contour line, and uses the control points to control the shape of the formwork. According to the precision requirements, when the height difference between the vertical rods of the optimized contour lines deviates more than the acceptable deviation, the V-shaped structure formed by bending the top steel pipe can be used to adjust the curve at the middle control point, so as to ensure the construction precision. When the height difference is within the acceptable deviation, the top steel pipe can be directly used as a straight steel pipe to reduce the workload.

[0034] 2. The present invention adopts double-layer wood to build a support system. The first wood is set up on two top horizontal support steel pipes. It is a short steel pipe used to simulate the slope of the curved surface between the two non-parallel steel pipes to ensure the construction accuracy of the curved surface. The second wood is placed flat and fixed to the first wood at both ends of the two non-parallel top horizontal support steel pipes in equal proportions to avoid the influence of the angle formed by the first wood, thereby improving the construction accuracy of the special-shaped hyperbolic surface. When the top horizontal support steel pipe is a V-shaped structure, the second wood is divided into two parts, left and right. When the top steel pipe is a straight steel pipe, the second wood can be used as a contour line between the optimized contour lines. Both cases can significantly improve the construction quality of the special-shaped hyperbolic surface.

[0035] 3. The present invention adopts large-scale wooden templates for large-surface paving, which significantly improves the material turnover, reduces construction costs and workload, improves the surface quality of finished products, and reduces later manual repairs.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Reference Figures 1-8 A special-shaped hyperbolic formwork support mechanism includes a special-shaped hyperbolic formwork support mechanism arranged between a wall 7 and a concrete floor pad 8. The special-shaped hyperbolic formwork support mechanism includes a formwork 2, multiple first-line wooden squares 3, multiple second-line wooden squares 4, a steel pipe bracket 5 and multiple fasteners 6. The steel pipe bracket 5 is fixedly constructed by multiple steel pipes and multiple fasteners 6 as a bottom support. The first-line wooden squares 3 are short wooden squares, and the second-line wooden squares 4 are long wooden squares. A double-layer wooden square is used to build a support system. The first-line wooden squares 3 are built on two top horizontal support steel pipes 15, which are short steel pipes for simulating curved surfaces. The slope between the two non-parallel steel pipes ensures the construction accuracy of the curved surface. The top of the steel pipe bracket 5 is fixed with multiple top horizontal support steel pipes 15 by fasteners 6. Multiple first wooden squares 3 are respectively set up between the two top horizontal support steel pipes 15. There is an adjacent junction 301 of the first wooden squares between the two top horizontal support steel pipes 15. There is an overlap angle 302 between the first wooden squares 3 and the steel pipe bracket 5. The overlap angle 302 between the first wooden squares 3 and the steel pipe bracket 5 changes irregularly between the two top horizontal support steel pipes 15, which conforms to the characteristics of the special-shaped hyperboloid and improves the construction accuracy.

[0047] The second wooden square 4 is fixed on top of the first wooden square 3 in a flat manner. The second wooden square 4 is fixed on the first wooden square 3 in a flat manner at both ends of two non-parallel top horizontal support steel pipes 15 in equal proportion, avoiding the influence of the angle formed by the first wooden square 3 and improving the construction accuracy of the special-shaped hyperbolic surface. The template 2 is fixed on top of the second wooden square 4.

[0048] In the present invention, the top horizontal supporting steel pipe 15 is fixedly connected by using two fasteners 6, and the first wooden square 3 and the top horizontal supporting steel pipe 15 are fixed by iron wire to increase the stability and strength of the connection.

[0049] In particular, the second wooden beam 4 is fixed on the first wooden beam 3 in equal proportion between the two non-parallel top horizontal supporting steel pipes 15, avoiding the influence of the angle formed by the first wooden beam 3 and improving the construction accuracy of the special-shaped hyperbolic surface.

[0050] It should be noted that the second wooden square 4 and the first wooden square 3 are fixed with iron nails, and the template 2 and the second wooden square 4 are fixed with iron nails. The iron nail fixation is more stable, and the template 2 and the second wooden square 4 are fitted together to form a special-shaped hyperbolic shape.

[0051] In the present invention, the thickness of the template 2 is 10 mm and a large template 2 is used to splice the special-shaped hyperbolic panel. The first wooden squares 3 at the adjacent junctions 301 are staggered and overlapped by 100 mm.

[0052] The present invention also proposes a support system for a special-shaped hyperbolic template mechanism, which is used to construct a special-shaped hyperbolic template support mechanism, including an original special-shaped hyperbolic surface contour line 9 and an optimized contour line 10. The optimized contour line 10 is formed by optimizing the original special-shaped hyperbolic surface contour line 9 of the special-shaped hyperbolic surface three-dimensional model in a curved instead of straight manner. The steel pipe bracket 5 is arranged by calculating the optimized contour line 10, and also includes a supplementary contour line 11, a bracket middle elevation control point 12, a bracket edge elevation control point 13 and a special-shaped hyperbolic surface edge elevation. The control point 14, the elevation control point 12 in the middle of the bracket, the elevation control point 13 at the edge of the bracket and the elevation control point 14 at the edge of the special-shaped hyperboloid are used to control the elevation of the template 2 at the control point. The supplementary contour line 11 is used to provide a fixed position for the first wooden beam 3 to reduce its cantilever length and improve the safety of construction. The on-site elevations of the elevation control point 12 in the middle of the bracket, the elevation control point 13 at the edge of the bracket and the elevation control point 14 at the edge of the special-shaped hyperboloid are used to establish a on-site model 17 for comparison with the design model 16 and for combination with other professional models.

[0053] In the present invention, the original irregular hyperbolic surface contour lines 9 are extracted from the irregular hyperbolic surface three-dimensional model in the form of equal elevation difference. When extracting the original irregular hyperbolic surface contour lines 9, the horizontal distance between the contour lines should be within the arrangement distance of the steel pipe support 5.

[0054] In particular, the shape of the original special-shaped hyperboloid contour line 9 is slightly curved, the optimized contour line 10 is non-parallel, and the top horizontal supporting steel pipe 15 is arranged along the direction of the optimized contour line 10.

[0055] It should be noted that the maximum deviation between the on-site elevation and theoretical elevation of the bracket middle elevation control point 12, the bracket edge elevation control point 13 and the special-shaped hyperboloid edge elevation control point 14 is 10mm. When the elevation difference between the bracket middle elevation control point 12 and the bracket edge elevation control point 13 exceeds 10mm, the top horizontal support steel pipe 15 is bent at the bracket middle elevation control point 12 to form a V-shaped horizontal support steel pipe 151 to meet the elevation requirements. At the middle control point, the curved surface can be adjusted by bending the top steel pipe to form a V-shaped structure to ensure the construction For work accuracy, when the elevation difference between the elevation control point 12 in the middle of the bracket and the elevation control point 13 at the edge of the bracket does not exceed 10 mm, the top horizontal support steel pipe 15 is a straight horizontal support steel pipe 152, and the second wooden square 4 is divided into two parts when the top horizontal support steel pipe 15 is a V-shaped horizontal support steel pipe 151. When the top horizontal support steel pipe 15 is a straight horizontal support steel pipe 152, when the elevation difference is within the acceptable deviation, the top steel pipe can directly use a straight steel pipe to reduce the workload, and the second wooden square 4 is used as the contour line between the optimized contour lines 10.

[0056] The present invention also provides a construction method for a special-shaped hyperbolic formwork support system, which is used to construct the special-shaped hyperbolic formwork support system, comprising the following steps:

[0057] S1: Create or obtain a three-dimensional model of a special-shaped hyperbolic surface;

[0058] S2: Extract the contour lines of the 3D model. The contour lines are extracted in the form of equal elevation differences. The extracted contour lines need to be projected onto a plane. Contour lines can also be extracted based on different elevation differences. It is necessary to ensure that the distance between two contour lines on the plane is no greater than the calculated distance of the steel pipe support 5.

[0059] S3: Optimize the contour lines by partition, and partition the area according to the characteristics of the special-shaped hyperboloid plate beam. In each area, the original special-shaped hyperboloid contour line 9 is optimized by replacing the straight line with a curved line to form an optimized contour line 10;

[0060] S4: Arrange the steel pipe uprights along the optimized contour line 10 according to the calculated spacing requirements;

[0061] S5: Set control points along the optimized contour line 10. The control points should include the support middle elevation control point 12, the support edge elevation control point 13, and the special-shaped hyperboloid edge elevation control point 14.

[0062] S6: Arrange the pole positions on site according to the drawings;

[0063] S7: erecting steel pipe support 5;

[0064] S8: Laying the first wooden plank 3;

[0065] S9: Laying the second wooden plank 4;

[0066] S10: Pre-lay formwork 2 and measure the elevation of control points;

[0067] S11: Adjust the elevation of the control point;

[0068] S12: Large surface paving template 2;

[0069] S13: Re-measure the elevation of the control point;

[0070] S14: Create a site model 17 and compare it with the design model 16.

[0071] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
