Description
Technical Field
The utility model belongs to the technical field of the prefabricated construction of beam slab, concretely relates to structure of prefabricated pedestal of reinforced concrete sheet metal.
Background
The reinforced concrete sheet prefabricated member is widely applied in the field of building engineering. Reinforced concrete slabs are usually prefabricated in a processing yard. The reinforced concrete thin slab has simple structure, small size and simple prefabrication method, and usually, a whole steel plate is laid on a hardened terrace as a bottom template, and the periphery of the bottom template encloses and blocks the side template. There is a problem in that the bottom mold plate is easily moved and is easily raised and deformed by the temperature, resulting in deviation in the size of the preform, thereby affecting the quality of the preform.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a prefabricated pedestal of reinforced concrete sheet metal is provided, the die block board warp when external temperature changes can be avoided, can effectively be fixed with the die block board, avoids the template to remove or warp and leads to the prefab size deviation to ensure the construction quality of prefab.
The technical scheme of the utility model as follows:
the utility model provides a prefabricated pedestal of reinforced concrete sheet metal which characterized in that: the concrete-filled terrace comprises a rectangular frame formed by welding 4 angle steels, wherein the frame is horizontally arranged on a hardened terrace, and pedestal concrete is poured in the frame; the angle steel is arranged in a reversed L shape, one side of each angle steel is flush with the top surface of the pedestal concrete and extends towards the outer side of the pedestal concrete, the other side of each angle steel is tightly attached to the side wall of the pedestal concrete, at least two vertical anchoring ribs are welded, the upper ends of the anchoring ribs are welded with the angle steel, and the lower ends of the anchoring ribs are anchored in the hardened terrace; the bed die plate is laid on pedestal concrete and frame top surface, the bed die plate includes the polylith along the horizontal rectangle steel sheet that sets up of pedestal concrete and frame, is equipped with 5 mm's clearance between the adjacent steel sheet, and the position that the steel sheet is located the angle steel top surface passes through a plurality of bolt fastening with the angle steel.
The utility model discloses but the shortcoming of displacement takes place easily when effective control pedestal die block board takes place to bulge or warp and concreting, can improve the construction quality of reinforced concrete sheet metal prefab.

Detailed Description
As shown in fig. 1 and 2, the utility model comprises a rectangular frame formed by welding 4 angle steels 2, wherein the frame is horizontally arranged on a hardened terrace 1, and pedestal concrete 3 is poured in the frame; the angle steels 2 are arranged in a reversed L shape, one side of each angle steel 2 is flush with the top surface of the pedestal concrete 3 and extends towards the outer side of the pedestal concrete 3, the other side of each angle steel 2 is tightly attached to the side wall of the pedestal concrete 3, at least two vertical anchoring ribs 4 are welded, the upper ends of the anchoring ribs 4 are welded with the angle steels, and the lower ends of the anchoring ribs are anchored in the hardened terrace 1; the bed die plate has been laid to pedestal concrete and frame top surface, the bed die plate includes the polylith along the horizontal rectangle steel sheet 5 that sets up of pedestal concrete and frame, is equipped with 5 mm's clearance between the adjacent steel sheet, and the position that the steel sheet is located the angle steel top surface is fixed through a plurality of bolts 6 with the angle steel.
The utility model discloses specific embodiment as follows:
firstly, as shown in fig. 3 and 4, a rectangular white line frame is drawn on a hardened terrace 1 according to the design position of a pedestal, at least two vertical anchoring ribs 4 are implanted into the terrace along each side of the line frame, and the height of the upper ends of the anchoring ribs 4 exposed out of the ground is not more than the width of the angle steel sides.
And each edge of the line frame is provided with an angle steel 2, and the length of each angle steel is as long as that of the corresponding line frame edge. The angle steel 2 is placed in a reversed L shape, one side of the angle steel is parallel to the horizontal plane and is positioned outside the wire frame, and the other side of the angle steel is vertically supported on the terrace 1 with the horizontal plane and is welded with the anchoring rib 4 on the corresponding wire frame side; the end parts of the adjacent angle steels are also welded.
Through the procedures, the construction of the frame of the pedestal is completed.
Then, as shown in fig. 5 and 6, the concrete 3 of the pedestal is poured into the frame of the 4 angle steel surrounding cities, the pouring height of the concrete is flush with the top surfaces of the horizontal edges of the angle steels 2, and the concrete surfaces are leveled.
Finally, as shown in fig. 1 and 2, a plurality of rectangular thin steel plates 5 are transversely paved on the top surfaces of the pedestal concrete 3 and the frame angle iron 2 along the pedestal concrete and the frame, and the pedestal concrete and the frame are completely covered by the plurality of thin steel plates to be used as a pedestal bottom template. A gap of 5mm is arranged between the adjacent thin steel plates to be used as an expansion joint, so that the thin steel plates are prevented from being deformed by heating; the two ends of the thin steel plate are aligned with the outer sides of the angle steel.
And a plurality of screw holes penetrating through the thin steel plate and the angle steel are formed along the horizontal edges of the 4 angle steels on the frame, the distance between every two adjacent bolt holes is 20-30 cm, and bolts 6 are installed in the screw holes to fix the thin steel plate and the angle steel.
