Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a method for supporting formwork of irregularly shaped concrete structures with decorative textures. Background Technology

[0002] Today, more and more architects are pursuing the unique atmosphere that the texture of concrete itself brings to daily living and social activity spaces, thus setting off a revolutionary wave of plain concrete decorative finishes (such as exposed concrete).

[0003] Currently, the main technical methods for creating decorative textures on irregular concrete surfaces include: directly customizing precast components and assembling them on-site, or customizing irregular metal templates and casting them on-site, and then carving decorative textures on the concrete surface after casting. Among these methods, precast components have a long production cycle and high cost, while custom-made irregular metal templates are also expensive and have a low turnover rate. In addition, the production cycle for carving is long, the tolerance for error in the carving process is low, and errors in local carving may affect the entire finish. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a formwork support method for irregularly shaped concrete structures with decorative textures. By refining the design of the three-dimensional model, the shape and size information of the first and second ribs are obtained so that they can be cut and assembled on site to form a grid structure for wooden formwork support. In addition, decorative textures are set on the surface of the wooden formwork so that the corresponding decorative textures can be directly formed on the concrete surface after the concrete is poured, avoiding the need for custom-made irregularly shaped metal formwork.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is a formwork support method for irregularly shaped concrete structures with decorative textures, comprising the following steps: Step 1: Construct a 3D model of the irregularly shaped concrete structure; Step 2: Cut the three-dimensional model horizontally at different elevations to obtain the horizontal contour lines of the three-dimensional model at different elevations, and form multiple first ribs by proportionally matching the shape and size information of multiple horizontal contour lines, and widen each of the first ribs; Step 3: Vertically section the 3D model at different horizontal coordinates to obtain the vertical contour lines of the 3D model at different horizontal coordinates, and form multiple second ribs by proportionally matching the shape and size information of multiple vertical contour lines. Step 4: On each of the second ribs, multiple slots are opened at intervals along the height direction on the side corresponding to the irregular concrete structure to be supported, so that multiple first ribs at different elevation positions can be locked in one by one. The depth of each slot is equal to the width of the corresponding locking node of the first rib. Step 5: First, vertically connect multiple second ribs to the designed installation positions, and then snap each first rib into multiple slots at the corresponding elevation positions to form a grid structure. The surface of the grid structure is adapted to the surface of the irregular concrete structure to be supported. Step 6: Lay out a wooden template based on the outer contour of the grid structure, and set a decorative texture on the surface of the wooden template.

[0006] A further improvement of the formwork method for irregularly shaped concrete structures with decorative textures in this invention is that, when performing step 2 above, the width of each first rib is not less than 150 mm.

[0007] A further improvement of the formwork method for irregularly shaped concrete structures with decorative textures in this invention is that, when performing step 3 above, it is determined whether the width of each second rib is less than 100 mm, and if the width is less than 100 mm, it is widened.

[0008] A further improvement of the formwork support method for irregularly shaped concrete structures with decorative textures in this invention is that, when performing step 5 above, a formwork frame is first erected on the side opposite to the formwork support at the designed installation positions of multiple second ribs, and then each second rib is placed at the corresponding designed installation position and connected to the formwork frame.

[0009] A further improvement of the formwork method for irregularly shaped concrete structures with decorative textures in this invention is that, before performing step 6 and after performing step 5, the three-dimensional model is divided into multiple grid units based on the grid structure, and multiple template units are formed by proportionally matching the size of each grid unit. When performing step 6, the multiple template units are connected to the corresponding positions on the grid structure, and adjacent template units are made to abut against each other.

[0010] A further improvement of the formwork method for irregularly shaped concrete structures with decorative textures in this invention is that each formwork unit includes a liner. When performing step 6 above, multiple liners are first connected to corresponding positions on the grid structure using self-tapping screws, and then a panel is laid on the surface of the multiple liners, the surface of which is provided with the decorative texture.

[0011] A further improvement of the formwork method for irregularly shaped concrete structures with decorative textures in this invention is that slots are spaced apart on the back of the lining plate to bend and fit the outer contour of the grid-like structure.

[0012] A further improvement of the formwork method for irregularly shaped concrete structures with decorative textures in this invention is that, before performing step 5 and after performing step 3, the thickness of the lining plate and the panel is obtained in advance. In the three-dimensional coordinate system of the three-dimensional model, multiple vertical contour lines are translated a distance away from the side to be supported relative to the three-dimensional model. The distance is equal to the sum of the thicknesses of the lining plate and the panel. The three-dimensional coordinates of each vertical contour line are obtained at this time. Based on the three-dimensional coordinates, the installation coordinates of each second rib are obtained. When performing step 5, each second rib is installed based on the installation coordinates.

[0013] Compared with the prior art, the advantages of the present invention are: 1. By refining the design of the 3D model, the shape and size information of the first and second ribs are obtained so that they can be cut and assembled on site to form a grid structure for the support of the wooden formwork.

[0014] 2. By setting decorative textures on the surface of the wooden formwork, the corresponding decorative textures can be formed directly on the concrete surface after the subsequent concrete pouring is completed. Attached Figure Description

[0025] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0026] The following detailed description of the formwork method for irregularly shaped concrete structures with decorative textures according to the present invention, with reference to the accompanying drawings and specific embodiments, will be provided in further detail.

[0027] Please see Figures 1-8 As shown, the formwork method for irregularly shaped concrete structures with decorative textures includes the following steps: Step 1: Construct a 3D model of the irregular concrete structure; Step 2: Cut the 3D model 1 horizontally at different elevations to obtain the horizontal outline of the 3D model 1 at different elevations, and form multiple first ribs 4 by proportionally matching the shape and size information of multiple horizontal outlines, and widen each of the first ribs 4. Step 3: Cut the 3D model 1 vertically at different horizontal coordinates to obtain the vertical contour lines of the 3D model 1 at different horizontal coordinates, and form multiple second ribs 2 by proportionally matching the shape and size information of multiple vertical contour lines. Step 4: On each of the second ribs 2, multiple slots are opened at intervals along the height direction on one side of the irregular concrete structure to be supported, so that multiple first ribs 4 at different elevation positions can be locked in one by one. The depth of each slot is equal to the width of the corresponding locking node of the first rib 4. Step 5: First, vertically connect multiple second ribs 2 to the designed installation position, and then snap each first rib 4 into multiple slots at the corresponding elevation position to form a grid structure. The surface of the grid structure is compatible with the surface of the irregular concrete structure to be supported. Step 6: Lay out a wooden template based on the outer contour of the grid structure, and set a decorative texture on the surface of the wooden template.

[0028] Specifically, the first rib 4 and the second rib 2 each correspond to the outer facade and inner facade of the three-dimensional model 1 respectively. When it is necessary to support the template of the corresponding side facade, the slot is opened on the corresponding side of the second rib 2.

[0029] Specifically, after performing step 5 above, the first rib 4 is connected to the second rib 2 using nails.

[0030] By setting nails to connect the first rib 4 and the second rib 2, the stability of the grid structure is improved.

[0031] Preferably, when performing step 2 above, the width of each of the first ribs 4 is not less than 150 mm.

[0032] By limiting the width of the first rib 4, its strength is ensured and subsequent damage is avoided.

[0033] Preferably, when performing step 3 above, it is determined whether the width of each second rib 2 is less than 100 mm. If the width is less than 100 mm, it is widened.

[0034] By limiting the width of the second rib 2, its own strength is ensured and subsequent damage is avoided.

[0035] Preferably, when performing step 5 above, the mold frame 3 is first erected on the back side of the multiple designed installation positions of the second ribs 2, and then each of the second ribs 2 is placed at the corresponding designed installation position and connected to the mold frame 3.

[0036] Specifically, the formwork 3 is a scaffold.

[0037] By setting up the mold frame 3, a connection foundation is provided for multiple second ribs 2, ensuring the connection stability of the subsequent mesh structure.

[0038] Preferably, before performing step 6 and after performing step 5, the three-dimensional model is divided into multiple mesh units based on the mesh structure. Multiple template units are formed by proportionally matching the size of each mesh unit. When performing step 6, the multiple template units are connected to the corresponding positions on the mesh structure, and adjacent template units are made to abut against each other.

[0039] Specifically, such as Figure 4 As shown, when dividing the plate seam, the peaks or troughs of the curved surface of the three-dimensional model 1 should be used as the dividing lines as much as possible to minimize the curvature of each template unit.

[0040] Preferably, each template unit includes a backing plate 5. When performing step 6 above, multiple backing plates 5 are first connected to corresponding positions on the grid structure using self-tapping screws, and then a panel is laid on the surface of the multiple backing plates 5. The surface of the panel is provided with the decorative texture.

[0041] The lining plate 5 is a load-bearing component during concrete pouring to prevent deformation under concrete pressure. The panel is a textured component to form a decorative texture on the concrete surface after the concrete is poured.

[0042] Specifically, after multiple lining plates 5 are laid in place, the surface of the lining plate 5 is polished to smooth the protrusions on the surface of the lining plate 5.

[0043] Specifically, the panel is an ultra-thin plastic structure that can bend and deform adaptably according to the surface shape of the backing plate 5. The panel is connected to the surface of the backing plate 5 by air nails and glue.

[0044] Specifically, the panel is composed of multiple panel units, with adjacent panel units abutting each other, and the seams between adjacent panel units are filled with sealant. The seams between adjacent panel units are staggered from the seams between adjacent backing plates 5.

[0045] Preferably, slots are spaced apart on the back of the liner 5 to bend and fit the outer contour of the mesh structure.

[0046] like Figure 7 As shown, the liner 5 is made of wood and has a certain degree of plasticity. When the bending range is large and the liner 5 cannot be bent to the correct position, the local thickness of the liner 5 is reduced by slotting along the bending direction on the back of the liner 5, making it easier to bend and increasing the bending range.

[0047] Preferably, before performing step 5 and after performing step 3, the thickness of the liner 5 and the panel is obtained in advance. In the three-dimensional coordinate system of the three-dimensional model 1, the multiple vertical contour lines are translated a distance away from the side to be supported relative to the three-dimensional model 1. The distance is equal to the sum of the thickness of the liner 5 and the panel. The three-dimensional coordinates of each vertical contour line are obtained at this time. Based on the three-dimensional coordinates, the installation coordinates of each second rib 2 are obtained. When performing step 5, each second rib 2 is installed based on the installation coordinates.

[0048] Specifically, the same method can be used to position each of the first ribs 4.

[0049] like Figure 3 As shown: the vertical outline, i.e. the translation distance of the second rib 2, is equal to the sum of the thickness of the liner 5 and the panel.

[0050] Specifically, after obtaining the installation coordinates of the second rib plate 2, a total station is used to mark the corresponding positions of the second rib plate 2 on the ground. Points at different elevations are distinguished by different paint colors to achieve the positioning of the second rib plate 2.
