Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a tower foundation chamfering construction device. Background Art

[0002] In the construction of power transmission line tower foundation, after the construction of the foundation concrete structure is completed, the edges of the concrete building need to be chamfered to reduce the problems of brittle cracking, surface peeling, edge damage, etc. in the straight-edged concrete structure, avoid secondary repairs, and thus improve the construction quality.

[0003] The utility model patent with patent number CN206941632U discloses a circular concrete chamfering tool, including a handle, a grip and a circular chamfering scraper, one end of the handle is connected to the handle, and the other end of the handle is welded to one side of the circular chamfering scraper, the two side surfaces of the circular chamfering scraper are perpendicular, and the two arc-shaped side edges of the circular chamfering scraper are blade-shaped; the handle and the thin-edge side of the circular chamfering scraper are 75°; the arc-shaped concave radius of the circular chamfering scraper is 40mm; the two side surfaces of the circular chamfering scraper are square; during construction, one side of the chamfering tool can be placed close to the template, and cutting can be performed along the circumference of the initially set concrete (about 2 hours after pouring), and its upper edge should be flush with the concrete surface. The manufactured concrete chamfered surface is smooth, the curve is smooth, the appearance is beautiful, and the chamfer is formed in one time, and there is no need to press and demold the concrete top angle, so as to achieve the purpose of one-time excellent foundation construction. In this patent, the edges and corners of the concrete foundation are cut by a circular chamfering scraper to achieve chamfering. However, during the chamfering construction process, the circular chamfering scraper is pushed to move by a manual handheld handle. During the movement of the circular chamfering scraper, there is uneven force causing the end of the circular chamfering scraper to penetrate into the concrete foundation, thereby cutting too deep to form a notch. At the same time, the sand and stone in the cut edges and corners are easily pushed, which will also form a notch and affect the chamfering quality. Utility Model Content

In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] In one embodiment, see Figure 1 The utility model discloses a tower foundation chamfering construction device, which comprises a chamfering component and a pushing component.

[0022] Among them, the chamfering component includes a plurality of groups of chamfered plates 1 arranged at intervals, the chamfered arc surface 2 is provided on the chamfered plate 1, an arc-shaped pressure-guiding end 3 is provided on the end of the chamfered plate 1, the outer arc end 8 of the pressure-guiding end 3 is connected with the inner arc end 9 of the chamfered arc surface 2 and has a smooth transition; the pushing component includes a support plate 4 arranged on the chamfered plate 1, a pushing rod 5 slidably arranged on the support plate 4, an elastic member 6 is provided on the pushing rod 5, and the axis of the pushing rod 5 is inclined relative to the outer arc end 8 of the chamfered plate 1 to form an angle α; the two ends of the elastic member 6 are respectively fixedly connected to the pushing rod 5 and the support plate 4.

[0023] For further information, see Figure 2 The chamfered plate 1 has flange plates 7 perpendicular to each other on both sides of its outer edge.

[0024] Preferably, the flange plate 7 is tangent to the chamfered arc surface 2 .

[0025] For further information, see Figure 3 The plane where the end of the pressure-guiding end 3 away from the chamfered plate 1 is located is higher than the outer arc end 8 of the chamfered plate 1 .

[0026] Preferably, the pressure-guiding end 3 is integrally formed with the chamfered plate 1. During use, the chamfered arc surface 2 contacts the corners of the concrete foundation, and the flange plate 7 is attached to the two sets of side walls of the concrete foundation. When chamfering, it is required to be two hours after the concrete is poured. During the movement of the chamfered plate 1, the pressure-guiding end 3 is arc-shaped and rises, and will not cut the concrete. At the same time, multiple sets of chamfered plates 1 move at the same time to avoid a single force acting on one set of chamfered plates 1, so that the chamfered plates 1 are stable and smooth during the movement, avoiding gaps in the corners due to uneven force, and pressing the corner concrete into the main foundation concrete to avoid gaps caused by cutting out sand and gravel.

[0027] For further information, see Figure 1 , and also includes a telescopic sleeve 10 sleeved on the outside of the elastic member 6, and the two ends of the telescopic sleeve 10 are fixedly connected to the push rod 5 and the support plate 4 respectively.

[0028] Preferably, the elastic member 6 is a spring, which is an existing structure, and the telescopic sleeve 10 is an elastic rubber sleeve, which is dustproof and waterproof.

[0029] For further information, see Figure 1 Two groups of chamfered plates 1 are arranged at intervals, and one end of the push rod 5 passes through one group of support plates 4 and there is a gap between the other group of support plates 4.

[0030] Preferably, one group of support plates 4 is provided with a sliding hole 11, and there is a distance between the push rod 5 passing through the sliding hole 11 and the other group of support plates 4, and the distance ranges from 2 cm to 4 cm.

[0031] For further information, see Figure 1 The angle α of the axis of the push rod 5 relative to the outer arc end 8 of the chamfered plate 1 ranges from 30° to 60°.

[0032] Preferably, a push handle 12 is provided on the end of the push rod 5 away from the support plate 4; the angle α is preferably 45°.

[0033] In this embodiment, two groups of chamfered plates 1 are arranged at intervals. In the process of pushing the push handle 12 to drive the push rod 5 to move, the push rod 5 transmits the force to the spring and the support plate 4, and then transmits it to the chamfered plate 1. The two groups of chamfered plates 1 are respectively subjected to the downward and horizontal forward forces (obtained from the force analysis of the force applied to the chamfered plate 1 by the inclined push rod 5). The two groups of chamfered plates 1 are combined with the pressure-guiding end 3 to prevent the chamfered plates 1 from being subjected to uneven force and cutting notches on the concrete corners. In the process of squeezing the corners of the concrete foundation, the two groups of chamfered plates 1 move steadily and smoothly to ensure the chamfering quality of the concrete foundation.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
