Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, and in particular to a curbstone demolding tool. Background Technology

[0002] Curbstones are strip-shaped structures between the road surface and the shoulder on both sides of a highway. Because they create a drop, resembling a cliff, the strip-shaped structure formed by the curbstone is also called a road cliff. The structural dimensions are usually 99cm*15cm*15cm, generally 10cm higher than the road surface. Curbstones are set on both sides of the median strip, side medians, and roadside strips. Curbstones can be divided into upright curbstones and flat curbstones. Upright curbstones are suitable for setting on both sides of the median strip, side medians, and roadside strips. When set on the median strip and side medians, the exposed height should be 15cm-20cm; when set on both sides of the roadside strip, the exposed height should be 10cm-15cm. Flat curbstones are suitable for setting between sidewalks and green belts, as well as at intersections or pedestrian crossings with accessibility requirements. Curbstones are generally required between the median strip and the road surface, and between the sidewalk and the road surface. In addition, curbstones are also set on traffic islands and safety islands.

[0003] According to the "A Quick Demolding Tool for Large Curbstones" provided in announcement number CN212764050U, the mold edge is first inserted into the groove parallel to the ground, then the mold is pulled up with the handle, and then pushed down in the opposite direction, allowing the curbstone to be demolded by its own weight. However, this causes the curbstone to fall to an uncontrollable height. When it falls from a high position, the edge of the curbstone will be damaged, which seriously affects the quality of the curbstone. Utility Model Content

Flip pins are fixedly installed on both the left and right sides of the square frame. A reset pin is fixedly installed on the side of the second support foot. A fixed rotating shaft is fixedly installed on the side of the square frame. A rotating sleeve is movably installed on the surface of the fixed rotating shaft. A U-shaped handle is fixedly installed on the surface of the rotating sleeve. A limit component is fixedly installed on the top of the square frame. Angle steel is fixedly installed on both the left and right sides of the bottom of the square frame. A limit strip is fixedly installed on the middle part of the bottom surface of the square frame away from the limit component.

[0010] Preferably, the distance between the two angle steels is adapted to the distance between the side plates on both sides of the template.

[0011] Compared with related technologies, the curbstone demolding tool provided by this utility model has the following beneficial effects:

[0012] This utility model provides a curbstone demolding tool. When using the demolding tool to separate the curbstone body from the template, the side of the curbstone body that is higher off the ground will be held in place by a limiting plate. Then, by pulling the handle, the curbstone body can be lowered from a relatively safe height, avoiding the risk of damage to the edge of the curbstone body from falling directly to the ground.

[0019] Example 1, by Figure 1-5 The present invention includes a square frame 1 and a demolding mold 10. A first support leg 2 is fixedly installed on one side of the square frame 1, and a second support leg 3 is fixedly installed on the other side of the square frame 1. Flip pins 4 are fixedly installed on both the left and right sides of the square frame 1. A reset pin 5 is fixedly installed on the side of the second support leg 3. A fixed rotating shaft 6 is fixedly installed on the side of the square frame 1. A rotating sleeve 7 is movably installed on the surface of the fixed rotating shaft 6. A U-shaped handle 8 is fixedly installed on the surface of the rotating sleeve 7. A limit component 9 is fixedly installed on the top of the square frame 1. Angle steel 11 is fixedly installed on both the left and right sides of the bottom of the square frame 1. A limit strip 12 is fixedly installed on the middle part of the bottom surface of the square frame 1 away from the limit component 9. The demolding mold 10 includes a template 101 and a curbstone body 102. A side of the template 101 is integrally formed with a side... The square frame 1 is composed of two horizontal steel plates and two vertical steel plates connected end to end. The square frame 1 is connected to the first support leg 2 and the second support leg 3 with reinforcing ribs. The size of the hollow in the middle of the square frame 1 is adapted to the size of the curbstone body 102. The limiting component 9 includes a fixed U-shaped block 91. A limiting plate 92 is movably installed inside the fixed U-shaped block 91. A limiting protrusion 93 is integrally formed on the side of the limiting plate 92. A handle 94 is fixedly installed at one end of the limiting plate 92. A connecting block 95 is fixedly installed at the top of the limiting plate 92. A tension spring 96 is fixedly connected to the side of the connecting block 95. The fixed U-shaped block 91 is fixedly installed at the top of the square frame 1. The other end of the tension spring 96 is fixedly installed on the side of the square frame 1. The distance between the two angle steels 11 is adapted to the distance between the two side plates of the template 101.

[0020] Working principle: When using the demolding tool to separate the curbstone body 102 from the template 101, the side of the curbstone body 102 that is higher off the ground will be held in place by the limiting plate 92. Then, by pulling the handle 94, the curbstone body 102 can be lowered from a relatively safe height, avoiding the risk of damage to the edge of the curbstone body 102 from falling directly to the ground.

[0021] Implementation steps:

[0022] Firstly, as Figure 1Align the side of template 101 with angle steel 11, then grasp the U-shaped handle 8 and flip it to achieve the desired shape. Figure 3 As shown in the diagram, the device is then flipped again. At this point, the entire device will fall freely, and the template 101 will separate from the curbstone body 102 due to its own weight. Figure 5 As shown, the side of the curbstone body 102 that is lower off the ground will fall directly to the ground, while the side that is higher off the ground will be held in place by the limiting plate 92. Then, by pulling the handle 94, the curbstone body 102 can be lowered from a relatively safe height, thus avoiding the risk of damage to the edge of the curbstone body 102 from falling directly to the ground.

[0023] In addition, rubber mats and other materials can be laid on the ground in advance to reduce damage to the curbstone body 102.
