Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of demoulding devices, in particular to a demoulding device for a basin-type plastic formwork for a small concrete component. Background Art
[0002] At present, a large number of small-scale prefabricated concrete components produced in factories are used in municipal roads, factory roads and courtyard roads, such as curbstones, drainage ditch covers, etc. The production processes are mainly dry hard concrete pressing and cutting process and basin-type plastic formwork belly casting platform vibration compaction process. The former has poor visual quality and high production equipment purchase cost, so the latter is more widely used.
[0003] For the basin-type plastic formwork belly casting platform vibration compaction process, the visual quality of the produced concrete components can achieve the effect of fair-faced concrete, and the market demand is large. However, when demolding, the formwork and concrete components need to be flipped over and knocked to demold the whole body. A concrete component often weighs 50 to 60kg, and manual flipping requires two people to complete. During the implementation process, the labor efficiency is low, the damage to the concrete components and formwork is relatively serious, the safety risk is relatively large, and the cost is high. For this reason, we propose a basin-type plastic formwork demolding device for small concrete components. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a demoulding device for a basin-type plastic formwork of a small concrete component, which can reduce the breakage rate of small prefabricated concrete components, reduce labor input, and increase the life of the formwork. The operation is simple, practical and effective, and can save costs, improve production efficiency, and reduce environmental pollution, and can effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a demoulding device for a small concrete component basin-type plastic formwork comprises a round steel pipe lever handle and a steel bar;
[0006] The steel bars include steel bar 1, steel bar 2 and steel bar 3, and the steel bar 1, steel bar 2 and steel bar 3 are all symmetrically distributed;
[0007] The right end of the round steel tube lever handle is welded to two symmetrically distributed welded bearing outer rings, and a steel bar 2 is welded to the inner ring of the bearing. The inner side of the steel bar 2 is welded to the outer wall of the angle iron 2. There are four angle irons 2 and their ends are cut into 45° bevels, butt-jointed in pairs and welded into a rectangular frame. Steel bars 1 are welded on the front and rear sides of the left end of the rectangular frame, and an angle iron 1 is welded on the upper side of the angle iron 2 on the left side. The two ends of the angle iron 1 are cut into 45° bevels and welded to each other. The middle part of the angle iron 2 on the left side is welded to the bottom of the high-strength spring, and the high-strength spring extends to the outside through the angle iron 1. A square steel pipe is welded on the right side of the angle iron 2 on the right side, and a steel bar 3 is welded on the upper side of the square steel pipe. The right side of the square steel pipe is welded to the arc edge of the semicircular steel plate, and rectangular steel plates are welded on the upper and lower sides of the semicircular steel plate. A rectangular limiting steel plate is welded to the bottom of the angle iron 2, and an angle iron slide is welded to the bottom of the rectangular limiting steel plate.
[0008] Figure 2 The black dashed and solid line segments in the middle are welds, i.e., the welding points between the semicircular steel plate and the rectangular steel plate. According to the three-dimensional size requirements of the concrete component, a demoulding device for the basin-type plastic formwork of a small concrete component can be designed and processed. When used in construction, the slideway mouth faces the flange of the basin-type plastic formwork. The operator pulls the handle backward to make the concrete component face the angle iron frame. The handle is raised to use the rectangular steel plate welded on the semicircular steel plate as the rotation axis, and the formwork is flipped to the ground with the steel bar as the fulcrum. At the moment of flipping, the high-strength spring touches the ground first to buffer the impact load, thereby reducing the loss rate of the formwork and the concrete component. The concrete component is demoulded under the action of gravity, and the formwork is pushed out along the slideway after demoulding. The handle is pressed down to use the steel bar as the fulcrum, and the rectangular steel plate welded on the semicircular steel plate as the rotation axis to return the device to its original position, and the demoulding work is repeated. The operation is simple, practical and effective, which can save costs, improve production efficiency and improve component quality.
[0009] Furthermore, the steel bar 1 is bent upward at 45° at a corresponding position to raise the height of the handle end. When the device is flipped and demoulded, the steel bar 1 is used as a lever fulcrum, and when the device is reset after demoulding, the steel bar 3 is used as a fulcrum, which is convenient for use.
[0010] Furthermore, the net size of the rectangular frame is 2 cm larger than the corresponding size of the concrete member and 4 cm smaller than the flange of the plastic formwork, the length of the high-strength spring is 3 cm higher than the thickness of the concrete member, the radius of the semicircular steel plate is 2 cm larger than the thickness of the concrete member, and the net distance between the two vertical sides of the angle iron is 1 cm larger than the outer dimension of the flange of the plastic formwork, which can reduce the impact load and is beneficial to protecting the formwork and concrete members.
[0011] Furthermore, wear-resistant rubber pads are attached to the upper and lower sides of the angle iron slideway with a high-strength adhesive to protect the template.
[0012] Furthermore, the size of the round steel tube lever handle is 30*3mm, the size of the angle iron one is 50*50*3mm, the size of the square steel tube is 50*50*3mm, the size of the angle iron two is 50*50*3mm, and the size of the angle iron slide is 30*30*3mm. Clearly defining the size can save costs without affecting its stability and can reduce environmental pollution.
[0013] Furthermore, the diameter of the steel bar is 20 mm, the thickness of the semicircular steel plate is 4 mm, the thickness of the rectangular steel plate is 4 mm, the thickness of the rectangular limiting steel plate is 4 mm, the thickness of the wear-resistant rubber pad is 3 mm, the bearing specification is 6206 type and is set at both ends, and the structure is stable and reliable.
[0014] Compared with the prior art, the utility model has the following beneficial effects: the demoulding device of the basin-type plastic formwork for small concrete components has the following advantages:
[0015] 1. When in construction, the slideway mouth faces the basin-type plastic formwork flange. The operator pulls the handle backward to make the concrete component face the angle iron frame. The handle is raised to use the rectangular steel plate welded on the semicircular steel plate as the rotation axis, and the steel bar is used as the fulcrum to let the formwork flip onto the ground. At the moment of flipping, the high-strength spring touches the ground first to buffer the impact load, thereby reducing the loss rate of the formwork and concrete components. The concrete component is demoulded under the action of gravity, and the formwork is pushed out along the slideway after demoulding. The handle is pressed down to use the steel bar as the fulcrum, and the rectangular steel plate welded on the semicircular steel plate as the rotation axis to return the device to its original position, and the demoulding work is repeated. The operation is simple, practical and effective, which can save costs, improve production efficiency and improve component quality.
[0016] 2. By raising the height of the handle end, the steel bar one is used as the lever fulcrum when the device is flipped and demoulded, and the steel bar three is used as the fulcrum when the device is reset after demoulding, which is convenient for use.
[0017] 3. By setting the length of the high-strength spring to be 3 cm higher than the thickness of the concrete component, the impact load can be reduced, which is beneficial to protecting the formwork and concrete components. BRIEF DESCRIPTION OF THE DRAWINGS
