Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wall verticality detection devices, in particular to a formwork wall verticality observation device. Background Art
[0002] In the existing technology, in the field of prefabricated formwork wall structure construction, the verticality of the formwork wall plays a vital role in the stability and quality of the entire building structure. The traditional method of adjusting the verticality of the formwork wall has many disadvantages. In the operational process, it is first necessary to accurately pop out a control line at a specific distance on the outside of the formwork wall. After the formwork wall is hoisted into place, a vertical plane that coincides with the control line is projected vertically with the help of a laser leveler. Subsequently, the verticality correction is achieved by adjusting the diagonal braces of the formwork wall. In this process, in order to determine whether the formwork wall is vertical, it is necessary to select positions of the formwork wall close to the four corner points and use a tape measure to measure the distances between these points and the vertical plane. Only when these four measured distances are all preset values can it be determined that the formwork wall has been adjusted to a vertical state.
[0003] The traditional method of adjusting the verticality of the formwork wall requires repeated adjustment of the diagonal braces and multiple measurements with a tape measure. The operation is cumbersome and leads to low work efficiency of construction workers. In addition, there are certain errors in manual measurement with a tape measure, making it difficult to ensure the accuracy and consistency of each measurement result. Utility Model Content

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.
[0028] Example 1
[0029] Reference Figure 1 , a verticality observation device for a formwork wall in this embodiment includes: a vertically established main bracket, a hanging connection position is provided at the upper end of the main bracket, an upper marking position and a lower marking position are respectively provided at the upper and lower symmetrical positions of the main bracket, a measuring component is provided on the main bracket, and the measuring component includes a plumb line and a plumb line hanging at one end of the plumb line, the other end of the plumb line is connected to the hanging connection position, when the formwork wall is perpendicular to the horizontal plane, the main bracket abuts and fits against the formwork wall, and the plumb line is collinear with the connecting line of the upper marking position and the lower marking position.
[0030] Reference Figure 1 and Figure 2 The main bracket includes a vertically erected frame, an upper bracket arranged at the upper end of the frame, and a lower bracket arranged at the lower end of the frame. The hanging connection position and the upper marking position are arranged on the upper bracket, and the lower marking position is arranged on the lower bracket.
[0031] The upper bracket is formed with an end surface that fits with the formwork wall.
[0032] The vertical main bracket serves as the core supporting structure of the entire observation device, and bears the important responsibility of connecting various components and ensuring their stable operation.
[0033] As the primary component of the main support, the vertical frame provides stable vertical support. The upper bracket, located at the upper end of the vertical frame, not only serves as a mounting platform for the suspension connection and upper marking points of the measurement assembly but also plays a key role in ensuring proper alignment with the formwork wall. The upper bracket forms a formwork-conforming end surface that conforms to the formwork wall. This end surface can be wrapped with a rubber material with a certain degree of elasticity and friction to prevent scratches on the wall surface during contact with the formwork wall.
[0034] The hanging connection position is used to connect the vertical line in the measuring component. When the vertical line is collinear with the connection lines of the upper mark position and the lower mark position, it can be determined that the formwork wall is in a vertical state.
[0035] The main bracket is provided with a fixing component for limiting the main bracket and fitting it to the formwork wall.
[0036] Reference Figure 1 The fixing assembly includes a bayonet arranged on the upper bracket, and the bayonet is arranged downward.
[0037] The stand comprises an outer stand and an inner stand. The outer stand is sleeved on the outer side of the inner stand. The side wall of the outer stand is provided with a through hole for fixing the inner stand. The through hole is provided with a fixing bolt that abuts the inner stand.
[0038] The overall height of the main frame can be changed by adjusting the relative positions of the outer and inner frames. The outer frame sidewalls feature through-holes for securing the inner frame, with bolts abutting against the inner frame. When needed, the bolts can be loosened to allow the inner frame to freely move within the outer frame. Once the desired height is reached, the bolts can be tightened to secure the inner frame within the outer frame.
[0039] Reference Figure 1 The upper bracket and the lower bracket are respectively movably connected to the vertical frame, and a limit plate is provided between the upper bracket and the lower bracket and the vertical frame respectively. The vertical frame, the upper bracket and the lower bracket are respectively provided with a cylindrical protrusion, and both ends of the limit plate are provided with a circular hole for the cylindrical protrusion to pass through. When the upper bracket and the lower bracket are respectively perpendicular to the vertical frame, the limit plate is clamped on the cylindrical protrusion through the circular hole, and an anti-drop cap is movably connected to the cylindrical protrusion.
[0040] The limiting plate is used to fix the upper bracket and the lower bracket so that the observation device presents a U-shaped structure, so that the end face can fit onto the formwork wall. The limiting plate is clamped on the cylindrical protrusion through the circular hole and then fixed by the anti-slip cap, realizing detachable and movable splicing, which is convenient for the storage of the observation device.
[0041] Reference Figure 3 The hanging connection position is provided with a winding wheel, and the vertical line is wound on the winding wheel. The winding wheel provides an orderly winding space for the vertical line, and the vertical line is wound on the winding wheel to avoid confusion and knotting of the vertical line.
[0042] Reference Figure 3 and Figure 4 The upper marking position and the lower marking position are respectively marked with ink lines.
[0043] Reference Figure 5 When working, first transport the observation device to the formwork wall to be measured, loosen the fixing bolts at the through-holes on the side walls of the outer frame, stretch or shrink the inner frame to the appropriate position, and then tighten the fixing bolts. Next, rotate the hinges between the upper bracket and the frame, and between the lower bracket and the frame, so that the end face of the upper bracket is aligned with the corresponding position of the formwork wall, and make the upper and lower brackets perpendicular to the frames respectively, fix them with limit plates, and tighten the anti-slip caps. Subsequently, hang the upper bracket on the horizontal steel bars so that the end face fits the formwork wall, lower the plumb line from the reel at the hanging connection position, let the plumb line droop naturally, and observe whether the plumb line is collinear with the connecting line of the upper and lower marking positions. If not, adjust the formwork wall diagonal brace until they are collinear, and the observation and adjustment of the verticality of the formwork wall is completed.
[0044] Example 2
[0045] Reference Figure 6 In this embodiment, a formwork wall verticality observation device can be used when no horizontal steel bars are provided. The fixing assembly includes a support seat provided on a lower bracket, and the lower bracket is movably connected to the support seat.
[0046] The upper bracket is formed with an end surface that fits with the formwork wall.
[0047] The movable connection can be a hinge, and the lower bracket is movably connected to the support seat. On the one hand, the support seat provides a stable bottom support for the entire device, so that the observation device can rotate around the hinge and ensure that the end face of the upper bracket can fit on the mold wall.
[0048] Reference Figure 7When working, hinge the observation device on the support seat so that the end face of the upper bracket is completely in contact with the formwork wall, lower the plumb line from the reel at the hanging connection position, let the plumb line droop naturally, and observe whether the plumb line is collinear with the connection line between the upper mark position and the lower mark position. If not, adjust the diagonal brace of the formwork wall until they are collinear. This completes the observation and adjustment of the verticality of the formwork wall.
[0049] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention.
