Description

Technical Field

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

[0002] Modern architectural designs are becoming more and more diverse. Special-shaped hyperbolic panels have been widely used in iconic buildings such as stadiums, theaters, museums and super high-rise buildings due to their unique shapes and functions. These panels not only meet aesthetic requirements, but also realize complex structural functions, so they are favored by many designers.

[0003] However, in the actual concrete pouring process, due to the complex spatial structure of the special-shaped hyperbolic panel and the difficulty in controlling the modeling accuracy, the construction is extremely difficult. At present, regarding the construction of special-shaped hyperbolic surfaces, if a predetermined steel formwork is used for construction, when there are multiple special-shaped structures in a project construction, the predetermined steel formwork cannot be reused due to its fixed shape, which will cause material waste, reduce the turnover of materials, and significantly increase the construction cost. When wooden formwork is used for direct splicing, it is necessary to cut the wooden formwork into small pieces and then splice them 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 formed surface is not necessarily a smooth surface, which requires manual repair later. Therefore, this method seriously increases the construction cost 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 cushion layer, the special-shaped hyperbolic formwork support mechanism comprising a formwork, a plurality of first wooden squares, a plurality of second wooden squares, 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 squares being short wooden squares, the second wooden squares being long wooden squares, a plurality of top horizontal supporting steel pipes being fixed on the top of the steel pipe bracket by fasteners, the plurality of first wooden squares being respectively arranged between two top horizontal supporting steel pipes, there being an adjacent junction of the first wooden squares between the two top horizontal supporting steel pipes, there being an overlap angle between the first wooden squares and the steel pipe bracket, the overlap angle between the first wooden squares and the steel pipe bracket changing irregularly between the two top horizontal supporting steel pipes;

[0008] The second wooden strip is fixed above the first wooden strip in a flat manner, and the template is fixed above the second wooden strip.

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

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

[0011] Furthermore, the second wooden beam is fixed to the first wooden beam by iron nails, the template is fixed to the second wooden beam by iron nails, and the template and the second wooden beam 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, and the first wooden squares at the adjacent junctions 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, support middle elevation control points, support edge elevation control points and special-shaped hyperbolic surface edge elevation control points. The support middle elevation control points, support 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 support middle elevation control points, support edge elevation control points and special-shaped hyperbolic surface edge elevation control points are used to establish a on-site model for comparison with the design model and for mold matching with other professional models.

[0014] Furthermore, the original contour lines of the irregular hyperboloid are extracted from the three-dimensional model of the irregular hyperboloid in the manner of equal elevation difference. When the contour lines of the original irregular hyperboloid are extracted, 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 special-shaped hyperbolic contour line is slightly curved, the optimized contour lines are distributed in a non-parallel manner, 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 requirement. 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 a special-shaped hyperbolic formwork support system, comprising the following steps:

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

[0019] 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 on the plane. Contour lines can also be extracted according to different elevation differences. It is necessary to ensure that the distance between two contour lines on the plane is not greater than the calculated distance of the steel pipe support;

[0020] S3: Optimize contour lines by partition, and partition according to the characteristics of the plate beam of the special-shaped hyperboloid. In each zone, the original contour lines of the special-shaped hyperboloid are optimized by replacing straight lines with curved lines to form optimized contour lines;

[0021] S4: Arrange the steel pipe uprights along the optimized contour line according to the calculated spacing requirements;

[0022] S5: Set control points along the optimized contour lines. The control points should include the elevation control points in the middle of the bracket, the elevation control points at the edge of the bracket, and the elevation control points at the edge of the special-shaped hyperboloid surface.

[0023] S6: Arrange the pole positions on site according to the drawings;

[0024] S7: erect steel pipe support;

[0025] S8: Laying the first timber plank;

[0026] S9: Laying the second timber plank;

[0027] S10: Pre-lay the formwork and measure the elevation of the control points;

[0028] S11: Adjust the elevation of the control point;

[0029] S12: Large surface paving formwork;

[0030] S13: Re-measure the elevation of the control point;

[0031] S14: Establish the on-site model and compare it with the design model.

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

[0033] 1. The present invention selects contour lines with appropriate elevation differences for linear optimization, sets up supporting poles on the linear contour lines, and sets elevation control points on the bottom of the curved surface on both sides and in the middle of the same contour line after optimization and at the curved surface boundary along the contour line after optimization, so as to control the shape of the template. According to the accuracy requirements, when the elevation difference deviation between the contour line poles after optimization is greater than the acceptable deviation, the curved surface can be adjusted at the middle control point by bending the top steel pipe to form a V-shaped structure to ensure the construction accuracy. When the elevation difference is within the acceptable deviation, the top steel pipe can directly use a straight steel pipe to reduce the workload.

[0034] 2. The present invention adopts double-layer wood planks to construct the support system. The first wood plank is erected on two top horizontal support steel pipes. It is a short steel pipe used to simulate the slope of the curved surface between two non-parallel steel pipes to ensure the construction accuracy of the curved surface. The second wood plank is placed flat and fixed to the first wood plank at both ends of the two non-parallel top horizontal support steel pipes in equal proportion, avoiding the influence of the angle formed by the first wood plank and 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 plank is divided into left and right parts. When the top steel pipe is a straight steel pipe, the second wood plank 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-block wooden formwork 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.

A plurality of top horizontal supporting steel pipes 15 are fixed on the top of the steel pipe bracket 5 by fasteners 6. A plurality of first wooden squares 3 are respectively set up between the two top horizontal supporting steel pipes 15. There is an adjacent junction 301 of the first wooden squares between the two top horizontal supporting 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 supporting 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 supporting 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 modeling. 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 using iron wires 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 modeling.

[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 offset and overlapped by 100 mm.

[0052] The present invention also proposes a support system for a special-shaped hyperboloid template mechanism, which is used to construct a support system for a special-shaped hyperboloid template, including an original special-shaped hyperboloid contour line 9 and an optimized contour line 10, wherein the optimized contour line 10 is formed by optimizing the original special-shaped hyperboloid contour line 9 of the special-shaped hyperboloid three-dimensional model in a curved manner instead of a straight one, and the steel pipe support 5 is arranged by calculating the optimized contour line 10, and also includes a supplementary contour line 11, a support middle elevation control point 12, a support edge elevation control point 13 and a special-shaped hyperboloid edge elevation control point 14. Control point 14, the elevation control point 12 in the middle of the support, the elevation control point 13 at the edge of the support 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, and the supplementary contour line 11 is used to provide a fixed position for the first wooden square 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 support, the elevation control point 13 at the edge of the support 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 joint molding 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 manner of equal elevation difference. When the original irregular hyperbolic surface contour lines 9 are extracted, 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 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 is 10 mm. 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 exceeds 10 mm, the top horizontal support steel pipe 15 is bent at the elevation control point 12 in the middle of the bracket 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. 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 left and right parts when the top horizontal support steel pipe 15 is a V-shaped horizontal support steel pipe 151.
