[0002] In construction engineering, cantilever beams are a common construction structure, and their structural stability has a significant impact on the entire building. Before construction, cantilever beams require formwork construction, and the verticality of the outer vertical formwork is one of the important factors affecting its structural stability. Currently, the verticality of the formwork is usually checked using a laser level, steel ruler, or plumb line and steel ruler. The verticality is then adjusted based on the test results, and after the adjustment is completed, it is measured again, and then adjusted again. This cycle of measurement-adjustment-measurement-adjustment is required to achieve the ideal verticality, which is time-consuming and inefficient. Summary of the Invention

Detailed Implementation

[0030] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are all within the scope of protection of this invention.

[0031] In the description of this invention, unless otherwise stated, the terms "left", "right", etc., indicate the orientation or state relationship based on the orientation or state relationship shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances. To more clearly illustrate this invention, the following embodiments provide a detailed description.

[0033] A verticality control structure for cantilever beam formwork includes a horizontal support plate 1, support plate struts 2, a vertical beam formwork 3, beam formwork diagonal struts 4, and a verticality adjustment component 5. The verticality adjustment component 5 includes an adjustment assembly and an upper steel wire rope 6 and a lower steel wire rope 7 connected to both ends of the adjustment assembly. The upper steel wire rope 6, the adjustment assembly, and the lower steel wire rope 7 are sequentially connected to form a straight line (hereinafter referred to as the adjustment line). The adjustment line is diagonally connected between the vertical beam formwork 3 and the horizontal support plate 1. The total length of the adjustment line is adjusted by the adjustment assembly. Since the horizontal support plate 1 is fixed, the verticality of the vertical beam formwork 3 changes when the length of the adjustment line changes, thereby adjusting the verticality of the beam formwork.

[0034] The two ends of the beam formwork diagonal brace 4 are connected to the vertical beam formwork 3 and the horizontal support plate 1, respectively, and a high-strength spring 14 is installed in the middle. The main function of the beam formwork diagonal brace 4 is to support the vertical beam formwork 3. When the verticality of the vertical beam formwork 3 is adjusted, the high-strength spring 14 can adapt to the adjustment and deform accordingly, so that the verticality of the vertical beam formwork 3 can still provide effective support for the vertical beam formwork 3 during and after the adjustment process. The use of a high-strength spring can ensure the support strength of the beam formwork diagonal brace 4.

[0035] A transverse strut 18 is provided between the two vertical beam formworks 3. Each end of the transverse strut 18 has a frustum-shaped block 19, which can also be replaced by a frustum-shaped rubber disc. The transverse strut 18 enhances the stability of the vertical beam formwork 3. In this invention, the length of the transverse strut 18 is fixed, and it is kept as horizontal as possible during support to ensure a fixed spacing between the two vertical beam formworks 3. The number and position of the transverse struts 18 between the vertical beam formworks 3 are determined according to the support requirements.

[0036] High-strength springs 14 are provided on the diagonal braces 4 of the beam formwork on both sides. The verticality adjustment component 5 is only set on the outer side of the right vertical beam formwork 3. When the verticality of the right vertical beam formwork 3 is adjusted by the verticality adjustment component 5, the distance between the transverse braces 18 and the two vertical beam formworks 3 is fixed because the verticality of the right vertical beam formwork 3 changes. Due to the action of the transverse braces 18 and the diagonal braces 4 of the left beam formwork, the distance between the two vertical beam formworks 3 remains unchanged. When the verticality of the right vertical beam formwork 3 changes, the verticality of the left vertical beam formwork 3 is adjusted accordingly under the action of the high-strength springs 14 of the diagonal braces 4 of the left beam formwork, thereby achieving simultaneous adjustment of the verticality of the two vertical beam formworks 3. This invention achieves synchronous adjustment of the two vertical beam formworks 3 by setting diagonal braces 4 with high-strength springs 14 on the outer side of the two vertical beam formworks 3 respectively and setting transverse braces 18 between the two vertical beam formworks 3.

[0037] The adjusting assembly includes a threaded cylinder 8, a fixed sleeve 9, an upper threaded rod 10, a lower threaded rod 11, and a fixed rod 12. The threaded cylinder 8 has upper and lower threads with opposite directions of rotation. The upper threaded rod 10 and lower threaded rod 11 each have external threads, and they are connected to the upper and lower ends of the threaded cylinder 8 respectively via the upper and lower threads. Due to the opposite directions of rotation of the upper and lower threads, when the threaded cylinder 8 is rotated, the upper threaded rod 10 and lower threaded rod 11 simultaneously retract inward or simultaneously extend outward, for example, as shown in the attached diagram. Figure 4 When the right-hand threaded cylinder 8 is turned, the upper threaded rod 10 and the lower threaded rod 11 simultaneously retract into the threaded cylinder 8, shortening the total length of the adjustment line. The adjustment line pulls the right vertical beam template 3 to the right; conversely, the right vertical beam template 3 is adjusted to the left. In this way, the verticality adjustment of the vertical beam template 3 is completed.

[0038] A fixed sleeve 9 is fitted over the threaded cylinder 8, and the fixed sleeve 9 and the threaded cylinder 8 are rotatably connected, with a portion of the threaded cylinder 8 protruding from the fixed sleeve 9. The purpose of the fixed sleeve 9 is to ensure that the threaded cylinder 8 can rotate while maintaining its position; that is, the threaded cylinder 8 can only rotate, not move. The threaded cylinder 8 is rotated by twisting the exposed section, with a portion protruding from the fixed sleeve 9. The main reason for fixing the position of the threaded cylinder 8 in this invention is that, since the vertical beam formwork 3 is basically vertical after construction, adjustments to its verticality are only minor. Therefore, it is necessary to minimize vibration of the adjustment lines, especially the upper and lower wire ropes 6 and 7. By fixing the position of the threaded cylinder 8, the upper and lower wire ropes 6 and 7 will not vibrate or sway during adjustment, allowing for precise fine-tuning of the verticality of the vertical beam formwork 3. The fixed sleeve 9 is fixed by at least two fixed rods 12. To ensure the stability of the fixed sleeve 9, three fixed rods are provided along the outer periphery of the fixed sleeve 9. The three fixed rods 12 are respectively fixedly connected between the fixed sleeve 9 and the horizontal support plate 1.

[0039] The threaded cylinder 8 and the fixed sleeve 9 can be connected by any rotational method. For example, grooves 15 are respectively provided on the outer wall of the threaded cylinder 8 and the inner wall of the fixed sleeve 9; bearings are used to secure the threaded cylinder 8 and the fixed sleeve 9 between the grooves 15, so that the threaded cylinder 8 and the fixed sleeve 9 are rotatably connected by the bearings. Bearings are provided at least at the upper and lower ends of the threaded cylinder 8 and the fixed sleeve 9.

[0040] During measurement, a plumb bob can be fixed to the fixed sleeve 9. Choose any two or more heights and use a ruler with a bubble level to measure the vertical distance between the plumb bob at different heights and the vertical beam formwork 3 on the right. If the distances are equal, the beam is vertical; if they are different, the beam is not vertical and adjustment is required.

[0041] As a preferred solution, to ensure successful verticality adjustment in one go, a measuring reference 1 is provided on the fixed sleeve 9. The measuring reference 13 is an arbitrary block structure with a vertical surface, which faces the vertical beam template 3. Since the bottom position of the vertical beam template 3 remains basically unchanged, the upper part is mainly adjusted when adjusting the verticality. Before adjusting the verticality, the vertical distance between the bottom of the vertical beam template 3 and the vertical surface of the measuring reference 13 is measured and the reading is recorded. During measurement and adjustment, a horizontally placed ruler is used to measure the vertical distance between the position of the vertical surface of the measuring reference 13 and the vertical beam template 3. When this vertical distance is the same as the previously measured reading, it indicates that the vertical beam template 3 is vertical; otherwise, it indicates that the vertical beam template 3 is not vertical. The length of the adjustment line is adjusted until the measured data is the same as the initial reading.

[0042] As a preferred embodiment, the outer end face of the vertical beam formwork 3 is provided with vertical plates 16 and horizontal plates 17; the vertical plates 16 are fixed at intervals on the outer end face of the vertical beam formwork 3; the horizontal plates 17 are fixed on the outer end face of the vertical plates 16, and the upper end of the upper steel wire rope 6 is connected to the horizontal plates 17. The vertical plates 16 and horizontal plates 17 can ensure the flatness of the vertical beam formwork 3.

[0043] The upper end of the beam formwork diagonal brace 4 is connected to the horizontal plate 17.

[0044] The method for controlling the verticality of beam formwork using the control structure of the present invention includes the following steps:

[0045] S1. Use a measuring ruler to measure the vertical distance between the lowest point of the vertical beam template 3 and the vertical plane of the measuring reference piece 13, and record the reading.

[0046] S2, use a measuring ruler to measure the vertical distance between the vertical surface of the measuring reference 13 and the vertical beam template 3 directly opposite it, and compare it with the data recorded in step 1;

[0047] S3. Based on the comparison results, rotate the threaded cylinder 8 until the measurement data in step 2 is the same as the recorded reading in step 1, thus completing the adjustment of the beam formwork verticality.

[0048] In this invention, hooks or rings for securing steel wire ropes are provided on the vertical beam template 3 and the horizontal support plate 1, respectively. Since securing steel wire ropes to the plate is a conventional structure and not an innovation of this invention, this invention will not elaborate on this.

[0049] 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.
