[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes

[0032] Embodiment 1. The purpose of this embodiment is to provide a multi-degree-of-freedom arc wire laying device, which is mainly used for the positioning of large-arc building construction. Aiming at the problems of inconvenient arc adjustment, low construction efficiency, and high operation difficulty of the existing arc wire laying device, this embodiment provides a multi-degree-of-freedom arc wire laying device

[0033] As Figures 1 - 5 shown in, a multi-degree-of-freedom arc wire laying device includes a middle sector unit 1, a side sector unit 2, an elastic tension bar 5, an adjustment block 4, and a hinge piece 8; the middle sector unit 1 is a sector structure, the side sector unit 2 is a structure of half of the middle sector unit 1, and the center lines of the middle sector unit 1 and the extended side lines of the side sector unit 2 are at the same center of the circle. Structurally, the side sector unit 2 is half of the middle sector unit 1, and this structure can ensure that the formed arc side lines are the same arc

[0034] An installation groove is provided at the outer splicing joint of the middle sector unit 1 and the side sector unit 2, and the hinge piece 8 is fixed in the installation groove, so that multiple middle sector units in the middle are connected to each other at the outer edge with the side sector units on both sides. During implementation, the installation groove is an embedded groove structure, and notches 9 are provided on the two sector units to accommodate the rotation space of the hinge piece; the two rotating pieces of the hinge piece 8 are fixed on the embedded groove by screws, and the middle rotating shaft is located in the notch 9

[0035] Fixed columns are provided at the lower parts of the two side sector units, and an elastic tension bar 5 is connected between the two fixed columns. In this embodiment, the outer sides of the sector units are connected to each other through the hinge piece 8 to form a structure that can swing and adjust, and the inner ends are tightened inward by the elastic tension bar 5 to make the inner ends gather, and the whole forms a sector structure, so that the wire laying device can adjust and adapt to different arcs

[0036] In order to adjust the radius of curvature of the arc, that is, to adjust the bending degree of the arc; there are adjustment areas 3 with the same size and shape between the center line of the middle sector unit 1 and the side sector unit 2, and the adjustment block 4 is fitted and installed in the adjustment area 3 to block the gap between the sector units, and as the adjustment block 4 advances into the adjustment area, the opening of the adjustment area is at different angles

[0037] When implemented, both sides of the adjustment area are standard fan-shaped structures. An inclined surface (non-standard fan shape) that gradually extends inward is provided at the lower part of the middle fan-shaped unit. An adjustment area is formed between adjacent inclined surfaces. The outside of the adjustment area is large and the inner end is small. The adjustment block is an inclined surface structure. As the adjustment block moves inward, the radian formed by the middle fan-shaped unit and the side fan-shaped unit can be gradually increased.

[0038] To facilitate the identification of the size of the radian, corresponding scales are provided on the middle fan-shaped unit, the side fan-shaped unit, and the adjustment block in this embodiment. To standardize the operation, a scribing hole is provided on the side fan-shaped unit, and the scribing hole extends along the side line of the side fan-shaped unit.

[0039] The specific identification method of the scale is as shown in Figure 5 ; By arranging reference scale lines on the adjustment block and standard scale lines on the side fan-shaped unit and the middle fan-shaped unit, when the reference scale line corresponds to the standard scale line, the vertical on the standard scale line represents the opening size of the side fan-shaped unit and the middle fan-shaped unit and the corresponding radius of curvature. By pre-marking the scale, the radius of curvature can be quickly adjusted on-site to adapt to the different radian scribing requirements on-site. As an example, in this embodiment, the fan radius of the middle fan-shaped unit is 20 for illustration.

[0040] It is known that the fan radius of the middle fan-shaped unit is 20 cm; then α + β = 20°;

[0041] The radius of curvature R = 20 + A; A is the distance from the vertex of the fan to the center of the radian;

[0042] Then ; ; Thus, A = ; Because α + β = 20°; Thus, A = ;

[0043] Thus, R = 20 + A = 20 + ; By transformation, R = 20(1 + );

[0044] Let = ; Then R = 20(1 + );

[0045] It is obtained that ; Thus, α = 2 * arctan

[0046] And the following table is obtained;

[0047]

[0048] As can be seen from the above table, in this embodiment, only the sector radius of the middle sector unit is taken as an example of 20 cm for illustration; through the adjustment of the adjustment block, a corresponding included angle is formed between the sector units, that is, by pushing the adjustment block to the corresponding scale, the corresponding angle and radian adjustment can be achieved; as the radius of curvature increases, the opening degree of each sector unit gradually increases.

[0049] This embodiment aims to adopt a semi - circle split into equal - sized sectors. The side sector unit has a structure that is half of the middle sector unit, so that the edge line of the side sector unit on the side is at the center of the arc of the radian. At the same time, scale lines are marked on the middle sector component and the adjustment block, which is convenient for construction workers to adjust on - site through the scale lines. In the present invention, the side sector unit and the middle sector unit are hinged to each other through a hinge piece, and the arc end is torsionally hinged. There is an adjustment area between each sector unit, and each adjustment area is the same. By adjusting the inner adjustment component, each sector unit can have different unfolding angles. By changing the position of the adjustment component, the middle sector unit and the side sector unit can have different radian values. The half - sector plays the role of keeping both horizontal rulers perpendicular to the arc in any case of adjusting the radian, thus meeting the diversified adjustment requirements.

[0050] In specific implementation, this embodiment provides a multi - degree - of - freedom arc wire - laying construction method.

[0051] Step 1: First, use a total station to measure three positioning points. Among them, the arc endpoint is positioning point a, the point on the arc diameter direction is positioning point b, and a point on the arc is positioning point c; for the construction layout of the main body, exterior decoration, etc.: First, use a total station to measure three positioning points. The arc endpoint is positioning point a, the point on the arc diameter direction is positioning point b, and a point on the arc is positioning point c. The distance between the three points is within the equipment size range. Fix the equipment through positioning points a and b, and use positioning point c for calibration. After verification, the wire - laying can start. Each time, it is necessary to control the marking at the marking hole as the auxiliary line of the second ruler; the specific positioning points a, b, and c are as Figure 3 shown in the figure.

[0052] Step 2: Verify the positions of the three points and mark them on the positioning points a, b, and c.

[0053] Step 3: Use the wire - laying device to adjust the radian of the wire - laying device according to the data to make it consistent with the radian of the wire to be laid.

[0054] Step 4: Align the side sector unit of the wire - laying device with positioning points a and b, and use it as the starting side. Use a marking tool to draw a line along the radian edge of the wire - laying device; then make a mark on the edge of the other side sector unit and use it as the starting side for the next wire - laying; during the marking operation, in this embodiment, the edge of the side sector unit and the mid - line position of the middle sector unit are preferentially selected and marked with a dotted line.

[0055] Step 5: Repeat Step 3 and Step 4 with the starting side as the boundary;

[0056] Step 6: Calibrate the placed arc with the positioning point c.

[0057] For the layout of the main body and the exterior decoration, due to limitations such as the formwork width and the width of the decorative patch, high precision is not required; for the layout of the arc of the window sill and the interior decoration, high precision is required. It can be considered to draw a 1-3 mm dotted line at each arc, with the dotted line being the center of the sector arc and the precision being between 1-3 mm.

[0058] In this embodiment, the maximum adjustable radian of the layout device is 5° to 170°, and the size of the layout device can be controlled between 1.5 ㎡ and 0.3 ㎡. Designed according to the precision requirements of the construction process: for the layout of the arc of the main body and the exterior decoration, due to limitations such as the formwork width and the width of the decorative patch, the maximum precision is restricted. A layout device with a diameter of 1.5 m can be designed, with the equal-sector degree being 10 degrees and the two ends being 5° sectors.

[0059] When laying out the arc-shaped window balcony and the interior arc-shaped design and construction, according to the axis positioning line, the layout end point, and the 20-line extended outward, determine the initial positioning point a and the positioning point b. Adjust the degree according to the layout arc. After adjustment, carry out the layout, and the layout is the same as the above steps; for the arc-shaped window sill and the interior arc-shaped design, etc., a layout device with a diameter of 0.4 m can be designed, which is small and convenient, and can continuously lay out arcs with different radian, making the interior design more free and simple.

[0060] Embodiment 2: In this embodiment, the structure of the layout device is further described.

[0061] In this embodiment, as shown in Figure 3 and Figure 6 there are jacket 10s arranged on the front and back sides of the middle sector unit 1 and the side sector unit 2; there are telescopic adjustment columns 11 arranged on the jacket 10, the middle sector unit 1, and the side sector unit 2. The telescopic adjustment column includes an adjustment sleeve and an adjustment rod. The adjustment rod is threadedly connected to the adjustment sleeve, and the adjustment sleeve is fixed on the jacket, the middle sector unit, and the side sector unit.

[0062] In this embodiment, by setting the jacket structure, it can ensure that the middle sector unit and the side sector unit are adjusted in the same plane, avoid arching up and down, causing angle deviation, and ensure the adjustment precision; at the same time, the telescopic adjustment column is combined with a horizontal bubble level to ensure the flatness of the layout device during construction and reduce the actual error.

[0063] Embodiment 3: In this embodiment, the structure of the adjustment block is further described.

[0064] In this embodiment, as shown in Figure 1 and 2As shown in the figure, one side of the adjustment block is a flat fitting surface, and the other side is an inclined adjustment surface, and interlocking teeth are arranged between the fitting surface and the contact surface of the middle fan-shaped unit.

[0065] In this embodiment, all adjustment blocks are pushed to corresponding points according to preset scales, so that each adjustment area has the same opening length. The adjustment blocks can be clamped by means of the tension of the elastic tie rods. The occlusal tooth structure arranged on the contact surface of this embodiment can improve the contact strength, prevent the adjustment blocks from retreating, causing changes in the opening size of the adjustment area, and prevent the structure from shaking during use, causing the curvature to deviate.

[0066] The above is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention should note that in the present embodiment, each adjustment area has a corresponding adjustment angle, and the fan-shaped unit is a fixed angle. When the curvature is expanded to different degrees, the adjustment area and the fan-shaped unit are evenly shared, so the center point of the fan-shaped unit can basically represent the arc of the curvature; by adjusting the adjustment component, the outer side of the fan-shaped unit can have a corresponding curvature, which is convenient to adjust and can adapt to different curvature requirements. It has a wide range of applications and provides a convenient adjustment device for implementing curvature marking. It has high measurement accuracy and fast speed. Through pre-designed scales, the curvature can be quickly adjusted, which reduces construction intensity and improves construction efficiency. Changes or replacements that can be easily thought of, such as the shape of the adjustment block, the size adjustment of the fan-shaped unit, and the radius adjustment should all be covered within the protection scope of the present invention.
