Description

Technical Field

[0001] The invention relates to the field of architectural decoration, and in particular to a method for constructing a woven complex curved surface space. Background Art

[0002] With the improvement of living standards, the demand for spiritual civilization continues to increase, which is also reflected in the field of architecture. The form of architecture is no longer a single structural form, and the materials are no longer a single concrete and steel bars. While pursuing quality, it is also required to improve aesthetics.

[0003] Existing technologies, such as the invention patent with application number CN201810498687.4, disclose a free-form surface weaving method for space decoration. A set curved surface skeleton is constructed by using hard materials, and the weaving material is woven tightly against the constructed curved surface skeleton. After weaving, the middle part of the curved surface skeleton is removed, and the outer contour of the original curved surface skeleton is retained. The woven product relies on the support of its own structure and the support of the outer contour of the original curved surface skeleton to remain unchanged and maintain the complex curved surface shape.

[0004] However, the skeleton completed by this method has the following problems:

[0005] (1) It is difficult to build a complex curved frame with hard materials, which is inconvenient to construct and not suitable for actual construction operations. In addition, the steel frame is built in the form of welding. Once there is an error or adjustment is required, the frame needs to be dismantled on a large scale.

[0006] (2) After the weaving is completed, the middle part of the curved skeleton is removed, which increases the labor workload and is time-consuming;

[0007] (3) After the construction is completed, if local repairs or cleaning are required, it will be difficult;

[0008] (4) If the central frame is removed and only the outer outline frame is retained, the strength of the building will be difficult to guarantee. Once problems occur in the woven material itself, the frame support will be lost. Summary of the Invention

[0009] In order to solve the above technical problems, the present invention provides a method for constructing a complex curved surface space with a woven shape. A curved surface skeleton is formed by combining a rigid skeleton with a non-rigid skeleton, and the skeleton is installed on the curved surface skeleton, thereby providing a guarantee for the quality of the building.

DETAILED DESCRIPTION

[0045] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0046] A method for constructing a complex curved surface modeling space of a woven shape, the method is used for constructing a complex curved surface modeling space, such as Figure 1 As shown, the following steps are included:

[0047] S1. Draw construction grid lines at the construction site:

[0048] A curved space model is created in 3D modeling software, such as Rhino or SketchUP. A planar projection of the curved space model on the bottom surface is drawn based on the curved space model. The planar projection is divided into several grids, and support plates are constructed according to the shape of the grids. The 3D coordinates of each node position of the grid corresponding to the curved space model are obtained, and the corner positions of the support plate correspond to the nodes of the grid, and the corner positions of the support plate coincide with the positions of the nodes of the grid in the curved space model.

[0049] Draw construction grid lines on the ground in proportion according to the plan projection drawing;

[0050] S2. Erect a rigid profile frame at the construction site;

[0051] Taking the curved space modeling of a straw hat as an example, the rigid outline skeleton is a ring steel beam 19, which is composed of several sections of arc-shaped steel pipe structures. The several sections of arc-shaped steel pipe structures are connected to form a closed ring steel beam, which serves as the rigid outline skeleton of the modeling. The ring steel beam 19 is lifted by a lifting device and its angle is adjusted by rope traction. Then, the ring is rigidly supported by the supporting structure 20. Figure 7 As shown, the support structure uses steel columns, which are V-shaped and supported below the annular steel beam 19, making the support more stable.

[0052] S3. Install the lifting device according to the construction grid line. Set the support plate 6 on the upper end of the lifting device. The support surface 6 is spliced to form the support surface 18:

[0053] The lifting device includes a plurality of support units 1, which are stacked and arranged. A support plate 6 is installed on the upper end of the uppermost support unit 1. The support plate 6 can adjust the height and angle relative to the top support unit 1. Specifically, Figure 3 As shown, the support unit is a square frame constructed of steel structure, and a support plate 6, a support column 3, a spherical shaft 5, and a positioning support 4 are provided above the top support unit 1. The spherical shaft 5 is installed at the lower end of the support plate 6, and the lower end of the support column 3 is vertically installed on the upper end surface of the top support unit 1. The upper end of the support column 3 is connected to the spherical shaft 5, and the support column 3 is connected to the support plate 6 through the spherical shaft 5. The support plate 6 can be adjusted in angle relative to the support column 3; a number of positioning supports 4 are arranged on the periphery of the support column 3. Taking four positioning supports as an example, the lower ends of the four positioning supports 4 are vertically installed on the upper end of the top support unit 1, and the upper end of the positioning support 4 is a free end. The length of the positioning support 4 can be adjusted. By adjusting the length of the positioning support 4, the free end of the positioning support can be against the support plate 6 from below, thereby realizing the angular positioning of the support plate 6.

[0054] The length of the support column 3 is adjustable. In this embodiment, the support column 3 comprises two sections, which are connected by a socket-type socket joint. Both sections are provided with a stopper hole 7. The lower support column is connected to and fixed to the upper end of the top support unit 1, and the upper support column is connected to and fixed to the spherical shaft 5. The upper support column can be moved upward or downward relative to the lower support column to achieve height adjustment. After adjustment, a stopper pin 8 can be inserted into the stopper hole 7 to temporarily fix the position of the upper and lower support columns. Similarly, the positioning support 4 can also comprise two sections, with two positioning supports arranged vertically and interlocked. The lower positioning support 4 is connected to and fixed to the upper end surface of the top support unit 1. The upper positioning support can be moved upward or downward relative to the lower positioning support. Both positioning supports are also provided with a stopper hole 7, and a stopper pin 8 is inserted into the stopper hole 7. The relative position of the upper and lower positioning supports is temporarily fixed by the stopper pin 8 inserted into the stopper hole 7. Of course, the positioning support 4 and the support column 3 can also use electric telescopic motors, hydraulic cylinders, pneumatic cylinders, etc., but the relative cost will be increased. In order to facilitate movement, wheels 2 such as universal wheels can be installed below the bottom support unit.

[0055] The support plate 6 is a polygonal flat plate, such as a quadrilateral, a triangle, etc., and a plurality of jacking devices are arranged in an array, and finally the support plates are spliced to form a support surface 18, such as Figure 5 shown.

[0056] When installing the lifting device, the following steps are included:

[0057] 1. According to the three-dimensional coordinates of the surface space model corresponding to the node at each grid position, select the height of the jacking device in proportion and initially move the jacking device into the grid;

[0058] 2. Use a total station to measure the plane coordinates of the corner 9 of the support plate, and adjust the position of the jacking device within the construction grid until the plane coordinates of the corner 9 of the support plate meet the plane coordinates of the curved surface space model at the corresponding position;

[0059] 3. Adjust the angle and height of the support plate, and measure the longitudinal coordinates of the corner 9 of the support plate by the total station until the longitudinal coordinates of the corner 9 of the support plate meet the longitudinal coordinates of the curved space model at the corresponding position.

[0060] Repeat steps 1-3 to complete the installation of the jacking devices in other locations, and the support plates are adjacent to each other to form a support surface.

[0061] S4. Install a non-rigid skeleton on the support surface. The non-rigid skeleton includes a plurality of connection units. The connection units are connected to form a mesh skeleton. The edges of the mesh skeleton are connected and fixed to the outline skeleton.

[0062] Among them, the connection unit is Figure 2As shown, it includes a connecting portion 10, a first end portion 11, and a second end portion 12. The first end portion 11 and the second end portion 12 are respectively arranged at both ends of the connecting portion 10. A plurality of connecting members are respectively connected to the first end portion 11 and the second end portion 12. Adjacent connecting units are connected by connecting members; a double-layer mesh structure is formed between the connecting units through the connecting members.

[0063] Specifically, the connecting portion 10, the first end portion 11, and the second end portion 12 can be an integral structure or can be three parts connected together. In this embodiment, the integral structure is taken as an example. The connecting portion 10 adopts a steel pipe structure, and the two ends of the steel pipe are respectively the first end portion 11 and the second end portion 12. Four reserved grooves 16 are respectively provided at the first end portion 11 and the second end portion 12. The reserved grooves 16 have openings, and a cover 13 is installed at the position of the opening. The opening of the reserved groove 16 is sealed by the cover 13; the connecting piece includes a connecting rod and a connecting head 15. The connecting rod can be The cylindrical rod can also be a flat connecting plate 14. Taking the connecting plate as an example, a cylindrical connecting head 15 is welded at one end or both ends of the connecting plate 14, and the diameter of the connecting head 15 is greater than the thickness of the connecting plate 14; for the connecting plate 14 connected between two connecting units, connecting heads 15 are installed at both ends of the connecting plate 14; for the connecting plate with one end connected to the connecting unit and the other end connected to the rigid contour frame, the connecting head 15 is set at the end of the connecting plate 14 connected to the connecting unit, and no connecting head is set at the end of the connecting plate 14 connected to the rigid contour frame.

[0064] Insert the connector 15 into the reserved groove 16 through the opening of the reserved groove 16, and then install the cover 13 to seal the opening of the reserved groove 16. The connector 15 cannot pass through the reserved groove 16, thereby realizing the movable connection between the connector and the first end and the connector and the second end. Figure 6 shown.

[0065] S5. Install the decorative layer on the mesh frame. Install the rattan on the mesh frame to form the decorative layer.

[0066] After the support surface 18 is formed, a mesh skeleton is installed on the support surface 18, that is, the connection unit is laid and installed on the support surface 18. Taking the space between two annular steel beams as an example, one of the annular steel beams is used as the starting position, and one end of the connector of the connection unit is welded and fixed to the annular steel beam. Of course, it can also be connected and fixed in other ways; then, the connector unit is laid along the support surface based on the installed connection unit, and the adjacent two connection units are connected by connectors until they extend to another annular steel beam, and the connection unit is welded and fixed to the annular steel beam through the connector, finally forming a double-layer mesh topology structure, that is, completing the installation of the non-rigid skeleton on the rigid skeleton.

[0067] After the non-rigid frame is installed, the decorative layer is installed. The decorative layer is installed with rattan. The rattan can be natural plant rattan, such as bamboo, or woven strips made of polymer materials. There is no limitation here and it can be selected according to needs. In this embodiment, bamboo pieces 17 are selected. Round holes are respectively opened at both ends of the bamboo pieces 17. When installing, the bamboo pieces 17 are installed on both sides of the connecting plate 14. The bamboo pieces 17 on both sides of the connecting plate 14 are connected by bolts, binding belts, etc. through the round holes. Figure 4 As shown; of course, the rattan can also be installed by using the longitudinal beam interlaced weaving method like bamboo weaving.

[0068] This embodiment is only a further explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
