Description

Technical Field

[0001] This invention belongs to the field of engineering construction technology, specifically relating to a support structure for an arc-shaped wall panel and its construction method. Background Technology

[0002] In engineering construction, when pouring curved wall panels at curved corners, curved formwork is required. To ensure the stability of the curved formwork during the concrete pouring process, a system with good support performance is needed. In existing technologies, the formwork support structure used for cast-in-place concrete construction in buildings generally uses steel or wooden beams assembled into formwork brackets, and steel or wooden poles are used to build scaffolding to support the brackets, which are then used in conjunction with steel formwork for concrete construction.

[0003] The existing support methods are mostly suitable for supporting strip-shaped templates with relatively regular shapes. However, when supporting curved templates, it is relatively complicated and difficult to erect brackets and steel pipe frames to meet the support requirements of curved templates. Therefore, there is an urgent need to propose a structure that can support curved templates. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a support structure for an arc-shaped wall panel and a construction method thereof, for providing stable support for the arc-shaped formwork during the concrete pouring process.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention discloses a support structure for an arc-shaped wall panel, comprising a column, wherein several sets of support components are provided along the height direction of the column, each support component including a mounting cylinder, the mounting cylinder being sleeved on the column and detachably connected to the column, several sets of main support units being provided on the outer surface of the mounting cylinder, each main support unit including a mounting ring, the mounting ring being rotatably connected to the mounting cylinder, a main threaded rod being provided on the outer surface of the mounting ring, one end of the main threaded rod being fixed to the mounting ring, and a main threaded sleeve being sleeved on the main threaded rod. The inner side of the threaded sleeve is threaded to the main threaded rod. Several sets of mounting rings of the support units are provided with several through holes around their circumference. At least one limiting ring is provided on the outer surface of the mounting cylinder. The inner side of the limiting ring is fixed to the mounting cylinder. The limiting ring is provided with limiting holes with the same number of through holes as the mounting ring. A limiting post is inserted into the limiting hole. The limiting post is inserted into one of the limiting holes of the mounting ring and one of the limiting holes of the limiting ring, in order to limit the rotation of the mounting ring.

[0007] Furthermore, the outer side of the mounting cylinder in the height direction is provided with several annular grooves, and the inner side of the mounting ring is sleeved in the annular grooves.

[0008] Furthermore, the inner side of the mounting cylinder is provided with an internal thread, and the outer side of the column is provided with an external thread, and the mounting cylinder is threadedly connected to the column.

[0009] Furthermore, a sleeve is installed on the outer side of the main threaded sleeve, and an internal thread is provided on the inner side of the mounting sleeve. An external thread is provided on the outer side of the main threaded sleeve. The mounting sleeve is threadedly connected to the main threaded sleeve. A connecting plate is symmetrically provided on the outer side of the mounting sleeve. One end of the connecting plate is fixed to the mounting sleeve. A secondary threaded rod is provided on the connecting plate. One end of the secondary threaded rod is rotatably connected to the connecting plate. A secondary threaded sleeve is sleeved on the secondary threaded rod, and the secondary threaded sleeve is threadedly connected to the secondary threaded rod.

[0010] Furthermore, a connecting block is provided at one end of the auxiliary threaded rod, and both the connecting block and the connecting plate are provided with insertion holes. The inner wall of the insertion hole is provided with several grooves on its outer circumference. A connecting post is provided in the insertion hole, and the connecting post is provided with several protruding ridges that match the number and shape of the grooves. The protruding ridges are engaged in the grooves.

[0011] Furthermore, a U-shaped clamping plate is provided on the outer end of both the main threaded sleeve and the auxiliary threaded sleeve. The closed end of the U-shaped clamping plate is connected to the end of the main threaded sleeve and the auxiliary threaded sleeve respectively, and a sleeper is clamped inside the U-shaped clamping plate.

[0012] Furthermore, the U-shaped clamp is rotatably connected to the ends of the main threaded sleeve and the auxiliary threaded sleeve, respectively.

[0013] A construction method for a support structure for an arc-shaped wall panel includes the following steps:

[0014] S1. Determine the installation position of the columns based on the location and curvature of the curved formwork on the outside of the curved exterior wall;

[0015] S2. Fix the column to the steel pipe frame near the curved formwork area, with the column located on the outside of the curved formwork;

[0016] S3. Determine the points where the curved formwork needs to be supported based on the erection height and length of the curved formwork;

[0017] S4. By rotating the installation cylinder, its position on the column is at the same height as the point where the curved formwork needs to be supported;

[0018] S5. By rotating the mounting ring, the main threaded sleeve is directed to the point where the arc-shaped template needs to be supported, and then the limiting post is rotated to lock it.

[0019] S6. Rotate the main thread sleeve to extend it and position the end of the main thread sleeve outside the support point of the arc template.

[0020] S7. Tap the anti-locking sleeper into the U-shaped clamping plate to make the anti-locking sleeper in close contact with the curved template and support the curved template.

[0021] The beneficial effects of this invention are as follows:

[0022] The design of this technical solution can provide stable and multi-point support for the arc-shaped template. At the same time, the angle and length of the support points in contact with the arc-shaped template can change accordingly, thereby supporting regular or irregular arc-shaped templates.

[0023] In this technical solution, multiple sets of support units are staggered vertically to avoid the problem of mutual interference caused by the excessively close spacing between multiple sets of support units when supporting small arc surfaces. At the same time, the support units can rotate and change length, which can support arc templates of different lengths and heights. Furthermore, the density of support in certain parts of the arc template can be adjusted according to the support needs of the arc template.

[0024] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0034] like Figures 1-6 As shown, the present invention discloses a support structure for an arc-shaped wall panel, including a column 1, which is preferably hollow to reduce the overall weight of the support structure. Several sets of support components are provided along the height of the column 1. In this specific embodiment, the number of support components is three sets. Each support component includes a mounting cylinder 18, which is sleeved on the column 1 and detachably connected to it. Several sets of main support units are provided on the outer surface of the mounting cylinder 18. In this specific embodiment, the number of support units is also three sets. Each main support unit includes a mounting ring 2, which is rotatably connected to the mounting cylinder 18. A main threaded rod 4 is provided on the outer surface of the mounting ring 2, and one end of the main threaded rod 4 is fixed. On the mounting ring 2, a main threaded sleeve 5 is sleeved on the main threaded rod 4. The inner side of the main threaded sleeve 5 is threaded to the main threaded rod 4. Several sets of mounting rings 2 of the support units are provided with several through holes 3 around their circumference. At least one limiting ring 14 is provided on the outer surface of the mounting cylinder 18. The inner side of the limiting ring 14 is fixed to the mounting cylinder 18. The limiting ring 14 is provided with limiting holes 15 with the same number of through holes 3 on the mounting ring 2. A limiting post 16 is inserted into the limiting hole 15. The limiting post 16 is inserted into one of the limiting holes 15 of the several mounting rings 2 located in any set of coaxially arranged through holes 3 of the several mounting rings 2 and one of the limiting holes 15 of the limiting ring 14, in order to limit the rotation of the mounting ring 2.

[0035] The working principle of the above technical solution is as follows:

[0036] When the curved template 17 needs to be supported before the curved wall is poured, the column 1 is first fixed to the ground or the erected steel pipe frame. Then, the mounting ring 2 is rotated so that the main threaded sleeve 5 in each support unit points to the position where the curved template 17 needs to be supported. Then, the rotation of the mounting ring 2 is restricted by inserting the limiting post 16 into the through hole 3 of the mounting ring 2 and the limiting hole 15 of the limiting ring 14. (It is easy to understand that the angle set by the adjacent through hole 3 is the minimum angle that the mounting ring 2 can rotate.) The principle of restriction is that since the limiting ring 14 is fixed to the mounting cylinder 18, the limiting post 16 can block and restrict it. Furthermore, by rotating the main threaded sleeve 5, the length of the main threaded sleeve 5 is extended and pressed against the outer surface of the curved template 17, thereby performing a pressing and supporting operation on the curved template 17.

[0037] The above technical solution, when providing support, firstly sets up multiple sets of support units, each of which can rotate relatively independently, thereby providing stable support for multiple points of the arc-shaped template 17. Simultaneously, since the main threaded sleeve 5 in each support unit can extend and retract independently, if the extension length of the main threaded sleeve 5 in each support unit is inconsistent, an arc-shaped support surface can be formed, thus providing stable support for the arc-shaped template 17. Furthermore, it is easy to understand that each support unit is equipped with a mounting ring 2, and the mounting rings 2 are evenly distributed on the mounting cylinder 18. The advantage of this arrangement is that the multiple sets of support units are staggered vertically, avoiding the problem of interference between the rotation of multiple sets of support units when supporting small arc-shaped surfaces due to excessively close spacing. In other words, this technical solution can provide stable and reliable multi-point support for both small and large arc-shaped surfaces.

[0038] In one feasible embodiment, a plurality of annular grooves are provided on the outer side of the mounting cylinder 18 in the height direction, and the inner side of the mounting ring 2 is fitted into the annular grooves. This rotating connection method is simple and can limit the position of the mounting ring 2 on the mounting cylinder 18 so that it can only rotate and cannot move up and down, that is, it will not change the spacing of the multiple sets of support units that are staggered.

[0039] In one feasible embodiment, the inner side of the mounting cylinder 18 is provided with an internal thread, and the outer side of the column 1 is provided with an external thread. The mounting cylinder 18 is threadedly connected to the column 1. The mounting cylinder 18 is threadedly connected to the column 1, that is, by rotating the mounting cylinder 18, the position of the support unit on the column 1 can be changed, thereby adapting to support the arc template 17 of different heights, or providing dense support for parts that need to strengthen the support effect.

[0040] In one feasible embodiment, a sleeve 7 is installed on the outer side of the main threaded sleeve 5, the inner side of the sleeve 7 is provided with an internal thread, the outer side of the main threaded sleeve 5 is provided with an external thread, the sleeve 7 is threadedly connected to the main threaded sleeve 5, a connecting plate 8 is symmetrically provided on the outer side of the sleeve 7, one end of the connecting plate 8 is fixed to the sleeve 7, a secondary threaded rod 12 is provided on the connecting plate 8, one end of the secondary threaded rod 12 is rotatably connected to the connecting plate 8, a secondary threaded sleeve 13 is sleeved on the secondary threaded rod 12, and the secondary threaded sleeve 13 is threadedly connected to the secondary threaded rod 12.

[0041] The auxiliary threaded rod 12 and auxiliary threaded sleeve 13 can form multi-point auxiliary support on the outside of the support points of the main threaded sleeve 5 and the arc template 17, further improving the support effect of the arc template 17. At the same time, the auxiliary threaded sleeve 13 can also change its length by rotation, thereby matching the curvature of the arc template 17 and providing stable and reliable support for the arc template 17. Meanwhile, the auxiliary threaded rod 12 is rotatably connected to the connecting plate 8, so the contact position between the end of the auxiliary threaded sleeve 13 and the arc template 17 can be changed by rotation, thereby providing support at a specified position. The mounting sleeve 7 is threaded to the outer surface of the main threaded sleeve 5, which can change the position of the mounting sleeve 7 on the main threaded sleeve, thereby further changing the length variation range of the auxiliary threaded sleeve 13 and increasing the rotation angle of the auxiliary threaded sleeve 13 (it is easy to understand that if the extension is too short and the rotation angle is too large, the end of the auxiliary threaded sleeve 13 will not be able to contact the arc template 17).

[0042] In one feasible embodiment, a connecting block 10 is provided at one end of the secondary threaded rod 12. Both the connecting block 10 and the connecting plate 8 are provided with insertion holes 9. The inner wall of the insertion hole 9 is provided with several grooves on its outer circumference. A connecting post 11 is provided in the insertion hole 9. The connecting post 11 is provided with several protrusions that match the number and shape of the grooves. The protrusions on the connecting post 11 are engaged with the grooves in the insertion hole 9. Since the connecting plate 8 is fixed, the connecting block 10 cannot rotate, thereby avoiding the problem of the secondary threaded sleeve 13 being subjected to force, which would cause the secondary threaded rod 12 to rotate. At the same time, when it is necessary to adjust the support angle, it can be achieved simply by pulling out the connecting post 11. It is easy to understand that the setting angle of the adjacent grooves is the minimum angle that the connecting block 10 can rotate and change.

[0043] In one feasible embodiment, a U-shaped clamping plate 6 is provided on the outer end of both the main threaded sleeve 5 and the auxiliary threaded sleeve 13. The closed end of the U-shaped clamping plate 6 is fixedly connected to the end of the main threaded sleeve 5 and the auxiliary threaded sleeve 13 respectively. The U-shaped clamping plate 6 is internally clamped with a sleeper 19. The sleeper 19 can change the point support to the surface support, further improving the support effect.

[0044] In one feasible embodiment, the U-shaped clamping plate 6 is rotatably connected to the ends of the main threaded sleeve 5 and the auxiliary threaded sleeve 13, respectively. The advantage of this rotatable connection is that, after the main threaded sleeve or the auxiliary threaded sleeve 13 extends to the designated position, the support direction against the sleeper 19 can be changed by rotating the U-shaped clamping plate 6, such as vertical support, diagonal support, or lateral support, thus meeting more support conditions.

[0045] A construction method for a support structure for an arc-shaped wall panel includes the following steps:

[0046] S1. Determine the installation position of column 1 based on the installation position and curvature of the arc-shaped formwork 17 on the outside of the arc-shaped exterior wall;

[0047] S2. Fix column 1 to the steel pipe frame near the area of ​​arc-shaped template 17, with column 1 located outside the arc-shaped template 17;

[0048] S3. Based on the erection height and length of the arc-shaped template 17, determine the points where the arc-shaped template 17 needs to be supported;

[0049] S4. By rotating the mounting cylinder 18, its position on the column 1 is at the same height as the point where the arc-shaped template 17 needs to be supported;

[0050] S5. By rotating the mounting ring 2, the main threaded sleeve 5 is directed to the point where the arc-shaped template 17 needs to be supported, and then the limiting post 16 is rotated and locked.

[0051] S6. Rotate the main thread sleeve 5 to extend the main thread sleeve 5 and position the end of the main thread sleeve 5 outside the support point of the arc template 17.

[0052] S7. Tap the anti-locking sleeper 19 into the U-shaped card plate 6 to make the anti-locking sleeper 19 in close contact with the arc-shaped template 17 and support the arc-shaped template 17.

[0053] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
