Description

Technical Field

[0001] The utility model belongs to the field of curbstones, and in particular relates to a curbstone backrest casting anti-pollution device. Background Art

[0002] In order to prevent the curbstone from being contaminated when pouring the curbback, measures should be taken to protect the installed curbstone. The current way to protect the curbstone from contamination is mostly to cover the curbstone with plastic film during concrete pouring. This traditional protection method consumes a lot of manpower, material resources and time. When covering, not only the covering height of the plastic film should be controlled to meet the exposed height of the curbstone, but also if the pouring distance is too long, the plastic film needs to be frequently transported for covering protection, which cannot guarantee the continuity of concrete pouring and can easily affect the appearance quality of the poured backrest.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0022] This embodiment includes a horizontal top template 1, and side templates 2 are symmetrically arranged downward at the left and right ends of the top template 1. Preferably, both the top template 1 and the side template 2 are steel templates, and the side template 2 is equal to the top template 1 in length. The distance between the two side templates 2 is equal to the width of the curb, that is, the inner surfaces of the two side templates 2 are just attached to the left and right outer surfaces of the curb. Generally, during construction, the length of the side template 2 or the top template 1 is selected to be 2-4 meters. The top template 1 and the two end side templates 2 form an inverted U-shaped cover on the curb to protect the curb surface from being contaminated.

[0023] Long square timbers 3 are symmetrically arranged on the left and right sides of the lower surface of the top template 1. The length of the long square timber 3 is equal to that of the top template 1. The upper surface of the long square timber 3 is fixed to the lower surface of the top template 1, and the side surface of the long square timber 3 close to the side template 2 is fixed to the inner surface of the side template 2, that is, the long square timber 3 is fixed at the right angle position surrounded by the top template 1 and the side template 2. The long square timber 3 is used to support the entire device to prevent the device from deformation.

[0024] A plurality of rollers 4 are evenly installed along the length direction of the top template 1 at the middle position of the lower surface of the top template 1. The rollers 4 are preferably universal wheels. The rollers 4 are installed on the adjustment block 5. The mounting plate 6 is fixed on the upper surface of the adjustment block 5. The mounting plate 6 is fixed to the top template 1 by screws. The vertical distance between the upper surface of the mounting plate 6 and the bottom end of the roller 4 is greater than the height of the long square wood 3. The roller 4 is placed on the upper surface of the curb. Therefore, the height of the entire device supported upward on the curb is determined by the vertical distance between the upper surface of the mounting plate 6 and the bottom end of the roller 4. The vertical distance between the upper surface of the mounting plate 6 and the bottom end of the roller 4 is equal to the height of the curb back cast. In this way, the height of the curb back cast can be controlled by controlling the vertical distance between the upper surface of the mounting plate 6 and the bottom end of the roller 4. The total height of the curb minus the height of the curb back cast is the exposed height of the curb. Therefore, in order to meet different design requirements, the present invention can design multiple groups of adjustment blocks 5 with different heights, and install the rollers 4 on the adjustment blocks 5 with different heights to adjust the exposed height of the curb.

[0025] Preferably, vertical scales (8) are provided downwardly on both sides of the upper edge of the side formwork 2. The scales (8) are fixed on the outer surface of the side formwork 2. The scales (8) are used to check whether the height of the curbstone back cast or the height of the curbstone exposed meets the design requirements. The scales (8) can also be used to judge whether the selected adjustment block 5 is incorrect, thereby playing a role of inspection.

[0026] A push rod 7 is provided obliquely upward on the top template 1, and the entire device is pushed to move by the push rod 7. Preferably, the push rod 7 is a telescopic rod, which is suitable for operation by workers of different heights.

[0027] When the present invention is used, the height of the adjustment block 5 installed on the roller 4 is selected according to the design requirements, and then the roller 4 and the adjustment block 5 of the appropriate height are installed together, and then the adjustment block 5 is fixed to the lower surface of the top template 1 through the mounting plate 6, and then the device is covered on the curb from top to bottom, the roller 4 is placed on the upper surface of the curb, and the side templates 2 on both sides are attached to the side surfaces of the curb. The curb back casting height or the curb exposed height is checked by a scale (8) to see whether it meets the design requirements, and then the curb back concrete is poured. As the pouring position changes, the push rod 7 is pushed to move the device synchronously with the pouring position, and protection can be provided during pouring.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
