Description

Technical Field

[0001] The invention relates to the technical field of construction tools, in particular to a bending special-shaped aluminum plate butt joint splicing adjustment fixer. Background Art

[0002] Special-shaped aluminum sheet is a multifunctional building material with the characteristics of light weight, high strength, corrosion resistance, fire resistance, easy processing and easy installation. Therefore, it is widely used in building curtain walls, indoor and outdoor decoration, ceilings, partitions, cylindrical objects, billboards and other fields. Special-shaped aluminum sheet has good decorative and practical properties and has a wide range of applications.

[0003] Compared with conventional plate-shaped aluminum plates, special-shaped aluminum plates have more structural shapes such as corners and arcs. Accordingly, when installing and connecting them, their processing precision is required to be higher than that of ordinary aluminum plates. At the same time, when assembling, if the seams between the special-shaped aluminum plates are not aligned, the assembly errors between the special-shaped aluminum plates will be gradually enlarged, and then the edges of the entire building curtain wall will have obvious problems such as dislocation and unevenness of the installation of the corresponding special-shaped aluminum plates.

[0004] Most of the errors that occur during installation are due to the need to leave gaps in the special-shaped aluminum panels during installation. Leaving gaps is an essential step in the installation of special-shaped aluminum panels. It can solve the expansion and contraction problems caused by environmental factors, make the splicing more flexible and firm, and increase the service life of the aluminum panels. However, in the process of leaving gaps, due to the errors in the width of the gaps and the uniformity of the gaps, it is easy to cause obvious misalignment or unevenness of the special-shaped aluminum panels at the ends, affecting the assembly accuracy and efficiency of the entire building curtain wall. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a bent special-shaped aluminum plate joint splicing adjustment fixture to solve the problem that during the assembly process of special-shaped aluminum plates, errors in the gap width and the uniformity of the joints are likely to occur between two adjacent special-shaped aluminum plates, thereby affecting the assembly accuracy and efficiency of the entire building curtain wall.

[0006] In order to achieve the above-mentioned object, the basic scheme of the present invention is as follows: a bending special-shaped aluminum plate seam splicing adjustment fixer, comprising:

[0007] Fixed pipe;

[0008] An adjusting rod, one end of which coaxially penetrates the fixed tube and is located inside the fixed tube; the adjusting rod can be axially moved and adjusted inside the fixed tube;

[0009] Several support units, each comprising a support rod, a support plate, and a sliding ring fixedly connected to the inner wall of a fixed tube; one end of the support rod abuts against the side wall of an adjustment rod located at one end of the fixed tube; one end of the support rod passes through the sliding ring and is fixedly connected to one side of the support plate; the other side of the support plate can abut against the edge side wall of the special-shaped aluminum plate; the support rod is arranged radially along the fixed tube, and a sliding hole is provided on the side wall of the fixed tube for radial movement of the support plate; a sliding return adjustment portion is provided between the support rod and the sliding ring;

[0010] One end of the adjusting rod close to the supporting rod is in a frustum shape coaxially arranged with the fixing tube.

[0011] The technical principle of the present invention is: when installing the special-shaped aluminum plate, hold the adjusting rod and the end of the fixing tube, and let the other end of the fixing tube be clamped between the installation gaps of two adjacent special-shaped aluminum plates, so that the support plate on the fixing tube is opposite to the edge side wall of the special-shaped aluminum plate.

[0012] Then, the width of the two relative support pieces is controlled according to the standard installation gap designed between the two special-shaped aluminum plates. At this time, the adjusting rod is adjusted along the circumference of the fixed tube, and the diameter of the contact point between the support rod and the adjusting rod becomes larger, and then the frustum-shaped part of the adjusting rod pushes the support rod to move outward from the fixed tube, so that the adjusting rod pushes several support rods to expand outward along the radial direction of the fixed tube, and the support rod simultaneously pushes the support piece to expand outward. When the spacing between the two relative support pieces is equal to the standard installation gap width, the adjustment of the adjusting rod is stopped; at this time, the entire seam splicing adjustment fixture is moved horizontally along the installation gap between the two special-shaped aluminum plates. In this process, the spacing between the two adjacent special-shaped aluminum plates can be adjusted, so that the installation gap finally formed between the two special-shaped aluminum plates meets the standard, thereby realizing the standard seam installation of several special-shaped aluminum plates, improving the installation accuracy of the special-shaped aluminum plates, and also improving the assembly accuracy and efficiency of the special-shaped aluminum plates.

[0013] After the adjustment and installation of two adjacent special-shaped aluminum plates are completed, the adjustment rod is adjusted in the opposite direction along the fixed tube, and the sliding return adjustment part drives the support rod and the support piece to return to their original state, making it easy to remove the entire seam splicing adjustment fixture from the installation gap. The seam splicing adjustment fixture is easy to use and can be disassembled and reused.

[0014] Furthermore, the sliding return adjustment part includes an elastic limiting ring, a protrusion and a spring. The limiting ring is coaxially fixed on the support rod, the end face of the limiting ring is opposite to the sliding ring, and the spring is coaxially installed between the sliding ring and the limiting ring. One end of the spring is fixedly connected to the end face of the sliding ring, and the other end of the spring is fixedly connected to the end face of the limiting ring; the side wall of the support rod is circumferentially provided with a groove for the protrusion to slide, and the protrusion is fixedly installed on the inner wall of the limiting ring.

[0015] Through the above-mentioned setting, when the support rod synchronously pushes the support plate to expand outward, the spring is stretched, and the support rod maintains a horizontal movement state under the limit of the protrusion and the groove; when the two special-shaped aluminum plates are adjusted and installed, the elastic potential energy of the spring is released, and the spring pulls the support rod back along the fit between the protrusion and the groove through the limit ring, so that the seam splicing adjustment fixture is restored to its original state, which is convenient for removing the seam splicing adjustment fixture after use.

[0016] Furthermore, it also includes an annular elastic limiting ring, which is coaxially sleeved outside the fixed tube, and the inner wall of the elastic limiting ring is fixedly connected to the side of the support plate away from the support rod.

[0017] Through the above-mentioned setting, the elastic limiting ring can enhance the coordinated contraction and expansion between several supporting pieces; when the seam splicing adjustment fixture is installed on two adjacent special-shaped aluminum plates, the elastic limiting ring can be against the side of the special-shaped aluminum plate close to the wall to achieve the limitation of the seam splicing adjustment fixture, which is convenient for checking the fit between the side wall of the special-shaped aluminum plate and the supporting piece, and is convenient for adjusting the installation gap between the two adjacent special-shaped aluminum plates.

[0018] Furthermore, it also includes a limiting bolt and a nut threadedly connected to the limiting bolt. The support plate is provided with a through groove arranged along the axial direction of the fixing tube. The limiting bolt passes through the through groove and is threadedly connected to the nut.

[0019] Through the above arrangement, the nut and the limit bolt are moved along the through slot. When the limit bolt and the elastic clamping ring are both tightened on both sides of the special-shaped aluminum plate, the nut is fixed to the limit bolt, thereby realizing the clamping installation of two adjacent special-shaped aluminum plates and the limiting fixation of the special-shaped aluminum plates, which is convenient for assembling and limiting several special-shaped aluminum plates in sequence, and realizing stable and efficient installation of the special-shaped aluminum plates.

[0020] Furthermore, an elastic retaining ring is coaxially fixedly provided between the limiting bolt and the nut, and the elastic retaining ring can be abutted against the inner wall of the through groove.

[0021] Through the above arrangement, when the limiting bolt and the nut move along the through groove, the elastic clamping ring is deformed and then slides in the through groove. When the limiting bolt and the elastic clamping ring are both pressed against both sides of the special-shaped aluminum plate, the nut, the limiting bolt and the elastic clamping ring stop sliding, and the elastic clamping ring is automatically locked on the special-shaped aluminum plate, which is convenient for fixing and limiting the special-shaped aluminum plate, and the position adjustment of the limiting bolt and the nut is convenient.

[0022] Furthermore, the through groove is arranged along the vertical center line of the support plate, and the support rod is fixedly connected to the center of the support plate. A vertical groove for the nut and the limit bolt to pass vertically is provided on one end of the support rod close to the support plate.

[0023] Through the above setting, the vertical groove can provide space for the movement of the nut, limit bolt and elastic clamping ring, making the position adjustment of the nut, limit bolt and elastic clamping ring more convenient, and facilitating the clamping and fixing of special-shaped aluminum plates of different specifications, so that the installation position remains stable when the special-shaped aluminum plate is spliced ​​with the adjacent special-shaped aluminum plate.

[0024] Furthermore, the middle portion of the adjusting rod is threadedly connected to the end portion of the fixing tube.

[0025] Through the above arrangement, it is convenient to rotate the conical part of the adjusting rod by screwing it, and at the same time, it can move circumferentially along the fixed tube, so that the diameter of the fitting part between the support rod and the conical part of the adjusting rod changes, which is then converted into radial movement of the support rod along the fixed tube, making it convenient to quickly and stably adjust the position of the support plate from the side of the special-shaped aluminum plate away from the wall.

[0026] Furthermore, a screw ring is fixedly mounted on one end of the adjusting rod away from the supporting unit.

[0027] With the above arrangement, when adjusting the position of the support piece, it is easier for construction workers to focus on the screwing ring, and screwing the adjustment rod is more labor-saving; at the same time, the entire seam splicing adjustment fixture is not easy to fall out of the hand.

[0028] Furthermore, anti-slip grooves are provided on the outer wall of the fixing tube near the screw ring.

[0029] The above arrangement makes it easier for construction workers to focus on the anti-slip grooves of the fixed pipe, making the adjustment of the adjustment rod more convenient and labor-saving.

[0030] Furthermore, the diameter of the truncated cone end of the adjusting rod decreases gradually toward the side away from the center of the adjusting rod; the end of the support rod close to the adjusting rod is an arc surface that fits the outer wall of the truncated cone end of the adjusting rod.

[0031] Through the above arrangement, when the adjusting rod is screwed into the fixed tube, the support piece is in an outwardly expanded state; otherwise, the support piece retracts into the sliding hole; through the setting of the arc surface, the ends of the support rod can fit more stably on the frustum-shaped structure of the adjusting rod, making the horizontal movement of the support rod more stable and efficient.

[0040] At the same time, if Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the sliding return adjustment part includes an elastic limiting ring 401, a protrusion and a spring 604, the limiting ring 602 is coaxially fixedly installed on the support rod 30, the end face of the limiting ring 602 is opposite to the sliding ring 601, and the spring 604 is coaxially installed between the sliding ring 601 and the limiting ring 602, one end of the spring 604 is welded to the end face of the sliding ring 601, and the other end of the spring 604 is welded to the end face of the limiting ring 602; the limiting ring 602 is located on the side of the sliding ring 601 away from the support rod 30; the elastic limiting ring 401 is coaxially sleeved outside the fixed tube 10, and the inner wall of the elastic limiting ring 401 is away from the support plate 40 One side of the support rod 30 is welded, and the elastic limiting ring 401 is a rubber ring; a through groove 402 is provided on the support plate 40 along the axial direction of the fixed tube 10, and the through groove 402 is provided along the vertical center line of the support plate 40, and the limiting bolt 501 passes through the through groove 402 and is threadedly connected to the nut 502, and an elastic tightening ring 503 is coaxially fixed between the limiting bolt 501 and the nut 502, and the elastic tightening ring 503 can be abutted against the inner wall of the through groove 402, and the elastic tightening ring 503 is also a rubber ring; a vertical groove 303 is provided on one end of the support rod 30 close to the support plate 40 for the nut 502 and the limiting bolt 501 to pass vertically.

[0041] In addition, a groove 302 for the protrusion to slide is provided on the side wall of the support rod 30 along the circumferential direction, and the protrusion is fixedly mounted on the inner wall of the limiting ring 602 .

[0042] When the bent special-shaped aluminum plate seam splicing adjustment fixture of this embodiment is used, the upper end of the fixing tube 10 is clamped between the installation gaps of two adjacent special-shaped aluminum plates, so that the support piece 40 on the fixing tube 10 is opposite to the edge side wall of the special-shaped aluminum plate, and the edge side wall of the special-shaped aluminum plate is located between the elastic limiting ring 401 and the limiting bolt 501; then the width occupied by the two opposite support pieces 40 is controlled according to the standard installation gap designed between the two special-shaped aluminum plates, and at this time, the adjusting rod 20 on the fixing tube 10 is screwed, and the adjusting rod 20 is screwed. 0 approaches the other end of the fixed tube 10. At this time, the frustum-shaped end of the adjusting rod 20 rotates and moves upward relative to the support rod 30. At this time, the diameter of the contact point between the support rod 30 and the adjusting rod 20 becomes larger, and then the frustum-shaped part of the adjusting rod 20 pushes the support rod 30 to move out of the fixed tube 10. The spring 604 is stretched, and the four support rods 30 synchronously push the four support pieces 40 to abut against the side walls of the two special-shaped aluminum plates.
