Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a retaining wall masonry slope control device. Background Technology

[0002] During the construction of retaining walls, difficulties and inaccuracies in slope control are common, resulting in poor appearance and, in severe cases, even collapse. Currently, construction workers typically use a plumb bob and steel ruler to measure and control the slope, or they fabricate simple wooden scaffolds on-site to control the slope according to the required gradient. Both methods have their limitations.

[0003] When using a plumb bob and steel ruler to measure and control the slope, it requires a high level of experience from the construction workers, cannot maintain continuous control, necessitates frequent measurements and adjustments, and results in inaccurate slope control. Furthermore, as the retaining wall height increases, this method becomes more difficult to operate and poses a greater risk to the workers. When using simple wooden scaffolds for slope control, these scaffolds are prone to deformation during construction, are difficult to install and secure, are large and heavy, easily disturbed by external forces, and result in inaccurate slope control, making it difficult to guarantee the overall quality of the retaining wall construction. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a retaining wall masonry slope control device to solve the problem that retaining wall masonry depends on the technical level of construction personnel and the slope control is inaccurate.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a retaining wall masonry slope control device, including a base, the base being quadrilateral, with reserved openings on a pair of opposite sides of the quadrilateral, a slope scale being fixedly connected in the reserved opening on one side, and a rotating shaft being provided in the reserved opening on the other side, and a triangular positioning rod being rotatably connected through the rotating shaft. The slope ruler has a double-layer structure, consisting of two L-shaped steel rulers fixed at their ends. The gap between the two L-shaped steel rulers serves as a sliding groove, into which a fixing rod is inserted. A positioning groove is provided in the middle of the L-shaped steel ruler, and a fixing groove is provided on the fixing rod. A positioning bolt is passed through the intersection of the positioning groove and the fixing groove to achieve fixation.

[0006] Furthermore, adjusting bolts are provided at each of the four corners of the base, and support feet are fixed to the lower ends of the adjusting bolts. Rotating the adjusting bolts levels the base; during adjustment, the support feet remain stationary, while the height of the four corners of the base changes under the action of the adjusting bolts.

[0007] Furthermore, a leveling bubble is provided at the center of the base for leveling. The horizontal state of the base is measured by observing the position of the leveling bubble. When the leveling bubble is centered, the base is horizontal.

[0008] Furthermore, the slope bar and the fixing bar are perpendicular to each other. The triangular positioning bar can rotate freely relative to the base, thereby achieving slope control of the retaining wall.

[0009] Furthermore, a stabilizing crossbar for reinforcement is provided between the slope bar and the fixed bar.

[0010] Furthermore, the slope bar is equipped with an extendable extension rod, and the tail end of the slope bar is equipped with a telescopic fixing buckle for securing the extension rod. When the construction height of the retaining wall exceeds the height of the slope bar, the extension rod inside the slope bar can be pulled out and the telescopic fixing buckle can be tightened to secure it, and the construction of the retaining wall can continue.

[0011] Furthermore, the length of the fixing groove is greater than or equal to half the length of the fixing rod, which facilitates the fixing of the slope scale.

[0012] Furthermore, a handle is provided at the end of the fixing rod to facilitate the adjustment of the position of the triangular positioning rod by construction personnel.

[0013] Furthermore, the L-shaped steel ruler is provided with scale lines, and the scale lines are marked with slope values, which are the slope of the slope bar. When the slope value pointed to by the lower edge of the fixing groove is m, the slope of the slope bar is m.

[0014] The usage process of this utility model is as follows: 1. Base Leveling: Place two sets of devices at both ends of the sloping retaining wall to be constructed, aligning the edge line of the device base with the toe line of the outer facade of the retaining wall. Adjust the height of the four corners of the base using the four adjusting bolts until the level bubble in the center of the base is centered. The base is now level. Use the same method to adjust the other device to make it level as well.

[0015] 2. Slope Adjustment: Determine the slope of the outer facade of the retaining wall to be constructed and remove the positioning bolts for later use. The construction worker rotates the fixing rod by the handle, observing the lower edge of the fixing groove until it aligns with the desired slope mark. Then, pass the positioning bolts through the positioning groove on the slope scale and tighten them with nuts. Use the same method to adjust the triangular positioning rod of the other device to the same slope position. Observe the level bubbles of both devices again. If the level bubbles shift, level the base again.

[0016] 3. Hanging the engineering line: After the two sets of devices are adjusted, as each layer of the retaining wall is built, the engineering line is hung on the slope rod of the two devices. When building, the bricklaying is carried out along the suspended engineering line to ensure accurate control of the slope of the retaining wall.

[0017] After the retaining wall on the slope is built, the slope control device for the retaining wall should be properly placed.

[0018] Compared with the prior art, the beneficial effects of this utility model are: The retaining wall masonry slope control device provided by this utility model has a simple structure. It uses a base combined with a triangular positioning rod to position the retaining wall slope and a slope ruler to accurately measure the slope value for direct reading, which is convenient for construction and can be reused. It is easy to operate, has little dependence on the technical level of construction personnel, saves time and labor, and achieves accurate control of the retaining wall slope, ensuring reliable construction quality. It can be widely used in the field of retaining wall masonry construction. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Reference Figure 1-4 The device shown is a retaining wall slope control device, including a base 1, which is quadrilateral. A set of opposite openings 11 are provided on one pair of opposite sides of the base 11. A slope gauge 3 is fixedly connected to one of the openings 11, and a rotating shaft 111 is installed in the other opening 11. A triangular positioning rod 2 is rotatably connected to the rotating shaft 111, and the support angle of the triangular positioning rod 2 is connected to the rotating shaft 111. One side of the triangular positioning rod 2 is a slope rod 21, and the other side is a fixing rod 22; the slope rod 21 abuts against the sloping retaining wall 5. (Reference) Figure 4 The slope ruler 3 has a double-layer structure, consisting of two L-shaped steel rulers 31 fixed at their ends. The gap between the two L-shaped steel rulers 31 serves as a sliding groove 32, into which a fixing rod 22 is inserted. A positioning groove 311 is provided in the middle of the L-shaped steel ruler 31, and a fixing groove 221 is provided on the fixing rod 22. A positioning bolt 4 is passed through the intersection of the positioning groove 311 and the fixing groove 221 to achieve fixation.

[0027] like Figure 3 As shown, adjusting bolts 12 are respectively provided at the four corners of the base 1, and support feet 13 are fixed to the lower ends of the adjusting bolts 12; a leveling bubble 14 is provided at the center of the base 1 for leveling. Rotate the adjusting bolts 12 to level the base 1. During adjustment, the support feet 13 remain stationary, and the height of the four corners of the base 1 changes under the action of the adjusting bolts 12. Observe the position of the leveling bubble 14 until the bubble is centered, then the surface of the base 1 is horizontal.

[0028] like Figure 2 As shown, the slope bar 21 and the fixed bar 22 of the triangular positioning rod 2 are welded perpendicularly to each other; a stabilizing crossbar 23 for reinforcement is provided between the slope bar 21 and the fixed bar 22. The triangular positioning rod 2 can rotate freely relative to the base 1, thereby controlling the slope of the inclined retaining wall 5.

[0029] Furthermore, the slope bar 21 is provided with an extendable extension bar 212 to adapt to the slope retaining wall 5 of different heights; the tail end of the slope bar 21 is provided with a telescopic fixing buckle 211 for fixing the extension bar 212.

[0030] Furthermore, the length of the fixing groove 221 is greater than or equal to half the length of the fixing rod 22, which facilitates the fixing of the slope gauge 3. A handle 222 is provided at the tail end of the fixing rod 22, which makes it easy for construction personnel to adjust the position of the triangular positioning rod 2.

[0031] Furthermore, the L-shaped steel ruler 31 is provided with a scale line 312, on which a slope value is marked. This slope value is the slope of the slope bar 21. When the slope value pointed to by the lower edge line of the fixing groove 221 is m, the slope of the slope bar 21 is m.

[0032] Please see Figures 1-4 The process of using a retaining wall masonry slope control device is as follows: 1. Leveling the base: Place two sets of devices at both ends of the sloping retaining wall 5 to be built, aligning the edge line of the device base 1 with the slope toe line of the outer facade of the sloping retaining wall 5. Adjust the height of the four corners of the base 1 by adjusting the four adjusting bolts 12 on the base 1 until the level bubble 14 in the center of the base 1 is observed to be centered. The base 1 is then level. Use the same method to adjust the other device to make it level.

[0033] 2. Slope Adjustment: Determine the slope of the exterior facade of the retaining wall 5 to be constructed, and remove the positioning bolts 4 for later use. The construction worker holds the handle 222 and rotates the fixing rod 22, observing the lower edge of the fixing groove 221 until it aligns with the scale line of the desired slope. Then, pass the positioning bolts 4 through the positioning groove 311 of the slope scale 3 and tighten them with nuts to secure them to the fixing groove 221 on the fixing rod 22. Use the same method to adjust the triangular positioning rod 2 of the other device to the same slope position. Observe the level bubble 14 of both devices again. If the level bubble 14 shifts, level the base 1 again.

[0034] 3. Hanging the engineering line: After the two sets of devices are adjusted, as each layer of the slope retaining wall 5 is built, the engineering line is hung on the slope rod 21 of the two devices. When building, the bricklaying is carried out along the suspended engineering line to ensure accurate control of the slope of the retaining wall.

[0035] Furthermore, when the height of the retaining wall 5 exceeds the height of the slope bar 21, the extension bar 212 inside the slope bar 21 can be pulled out and the telescopic fixing buckle 211 can be tightened for fixation. Then, the construction line is suspended on the extension bar 212 to continue building the retaining wall.

[0036] After the slope retaining wall 5 is completed, the slope control device for the retaining wall should be properly placed.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
