Description
Technical Field
The utility model belongs to the technical field of the road construction, concretely relates to fill out roadbed side slope protection shedder for concrete prefabricated component.
Background
The highway fill subgrade side slope protection project adopts a precast concrete arch skeleton structure form in design. The prefabricated parts are processed and manufactured in a centralized manner in a small prefabricated part factory, and a plastic shaping mold which is provided by the factory and has high strength, high rigidity and difficult deformation is adopted as a template. And the formwork is removed 24 hours after the concrete prefabrication is finished, so that the turnover speed can be increased. In the past, the small prefabricated part is demolded by a plastic hammer generally, but the strength of the method is difficult to control, the demolded part is frequently damaged by corner falling, and a plastic mold is easily damaged and deformed by the knocking of the plastic hammer.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing a fill roadbed side slope protection shedder for concrete prefabricated component.
The utility model adopts the following technical scheme for accomplishing the above purpose:
a demoulding device for a prefabricated concrete component for protecting a side slope of a filling roadbed is provided with a steel reinforcement framework; the steel reinforcement framework is provided with two arc-shaped steel reinforcements which are arranged in parallel: the two arc-shaped reinforcing steel bars are different in length; the two arc-shaped reinforcing steel bars are connected into a reinforcing steel bar framework with an isosceles trapezoid cross section through two oblique reinforcing steel bars; equal angle steel used as handles is symmetrically welded on the two arc-shaped steel bars; the upper end surfaces of the side plates of the equal-edge angle steel are higher than the upper end surfaces of the corresponding arc-shaped reinforcing steel bars, and a gap is formed between the side plates of the equal-edge angle steel and the corresponding arc-shaped reinforcing steel bars;
gaps between the side plates of the equal-edge angle steel and the corresponding arc-shaped reinforcing steel bars form gaps for clamping the clamping edges of the die; a hoop I is welded on the upper end face of each oblique steel bar; the hoop I is of a structure which is inclined upwards and outwards; a hoop II is welded on the lower end face of the oblique steel bar corresponding to the hoop I; the hoop II perpendicular to the slant reinforcing steel bar set up, just hoop II inwards sunken and the hoop II on another slant reinforcing steel bar form together and are used for carrying out the tight mechanism in top to the mould.
The inclination angle of clamp I is 30.
The utility model provides a pair of fill out roadbed side slope protection shedder for concrete prefabricated component adopts above-mentioned technical scheme for the component can not be damaged and drawing of patterns is fast after the drawing of patterns, has effectively solved reasonable drawing of patterns problem.

Detailed Description
The invention is described in connection with the accompanying drawings and the embodiments:
as shown in fig. 1, 2 and 3, a demoulding device for a prefabricated concrete member for filling a roadbed slope protection, which is provided with a steel reinforcement framework; the steel reinforcement framework is provided with two arc-shaped steel reinforcements 1 which are arranged in parallel: the lengths of the two arc-shaped reinforcing steel bars 1 are different; the two arc-shaped steel bars 1 are connected into a whole through two oblique steel bars 3 to form a steel bar framework with an isosceles trapezoid cross section; equilateral angle steels 2 used as handles are symmetrically welded on the two arc-shaped reinforcing steel bars 1; the upper end surface of the side plate of the equal-edge angle steel 2 is higher than the upper end surface of the corresponding arc-shaped steel bar 1, and a gap is formed between the side plate of the equal-edge angle steel and the corresponding arc-shaped steel bar; gaps between the side plates of the equal-edge angle steel 2 and the corresponding arc-shaped reinforcing steel bars form gaps for clamping the clamping edges of the die; a hoop I4 is welded on the upper end face of each inclined steel bar 3; the hoop I4 is of a structure which is inclined upwards and outwards; a hoop II 5 is welded on the lower end face of the oblique steel bar corresponding to the hoop I4; II 5 perpendicular to of clamp the setting of slant reinforcing bar, just II 5 common formation of clamp on sunken and another slant reinforcing bar of clamp be used for carrying out the tight mechanism in top to the mould.
The inclination angle of clamp I4 is 30.
Utilize shedder carry out the structure of drawing of patterns as follows:
the first step is as follows: as shown in figure 4, the prefabricated concrete member and the mould are placed into a demoulding device, the clamping edge of the mould is clamped with a clamp I (with an included angle of 30 degrees) 3cm above the framework, and the clamp is vertically slightly sunken inwards to be the largest in jacking force with the plastic mould at the position.
The second step is that: as shown in fig. 5, the demoulding device is provided with the prefabricated part and the plastic mould, the angle steel handle is held by hands to be reversely lifted, the surface thread of the vertical slightly inwards-concave hoop of the framework is firmly propped against the plastic mould and has enough upward friction force, then the framework is manually and slowly lifted, the concrete prefabricated part can be automatically demoulded and fall under the action of self weight, and the demoulding is completed.
