Description

Top die for prefabricated reinforced concrete column

Technical Field

The utility model belongs to the assembly type structure field, in particular to a top mould for prefabricating reinforced concrete post.

Background

The beams, columns, plates and the like of the prefabricated building are prefabricated PC components in a re-factory, and the main work of a construction site is to assemble the PC components and cast-in-place treatment at the splicing positions during assembly so that the whole prefabricated building has good overall performance.

When the prefabricated column is prefabricated in a factory, the main reinforcement extending section with a certain length needs to be reserved at the top of the prefabricated column to serve as a steel rib of a cast-in-place node, so that a mounting hole through which a main reinforcement penetrates needs to be reserved at a position corresponding to the main reinforcement in a top die during the prefabricated column, and the aperture of the mounting hole is slightly larger than the diameter of the main reinforcement. The number of main reinforcements in the prefabricated column is generally 8-16, and even if holes are blocked during prefabrication, concrete can overflow from all the mounting holes. The overflowing materials are difficult to clean after solidification, so that the mold is difficult to remove, and time and labor are wasted. In addition, the overflowing concrete is inevitably knocked to damage the formwork and the molding quality of the prefabricated column due to knocking.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a form removal convenient and fast just can avoid damaging the top mould of template and prefabricated post shaping quality.

The utility model provides a top mould for prefabricating reinforced concrete post, including bottom plate, main muscle locating plate and link, there is main muscle constant head tank on the main muscle locating plate, and polylith main muscle locating plate spelling can make every main muscle location in the periphery of bottom plate, and the link can be dismantled through the fastener and connect in the outside of bottom plate and main muscle locating plate and form a whole top mould.

In an embodiment of the above technical scheme, the size and shape of the bottom plate are matched with the shape and size surrounded by the main ribs of the prefabricated column steel reinforcement cage, and the outer edge of the bottom plate is limited by the main ribs.

In an embodiment of the above technical scheme, the main rib positioning plate is a strip-shaped plate, the inner side of the length direction of the main rib positioning plate is provided with a U-shaped groove corresponding to the position of the main rib, the width of a notch of the U-shaped groove is matched with the diameter of the main rib, and the main rib penetrates through an arc section of the U-shaped groove.

In one embodiment of the above technical solution, thick nuts are welded to the upper sides of the bottom plate and the main rib positioning plate, respectively.

In an embodiment of the above technical scheme, the connecting frame is a # -shaped frame body, threaded holes are respectively formed in positions on the connecting frame corresponding to the thick nuts on the bottom plate and the main rib positioning plate, and the connecting frame is fixedly connected with the bottom plate and the main rib positioning plate through matched bolts.

The utility model discloses set up polylith main muscle locating plate, through the location basis of the bottom plate as main muscle locating plate with the matching of prefabricated post steel reinforcement cage inner chamber, set up the main muscle constant head tank on each main muscle locating plate, with polylith main muscle locating plate spelling connect them into whole spare through link and fastener after the bottom plate is peripheral, main muscle is reserved the section and is stretched out from the main muscle constant head tank respectively. After the column body is prefabricated, the fastening piece is detached, the connecting frame is taken down along the height direction of the main ribs, then the main rib positioning plates are taken down along the direction of the main rib positioning grooves, and finally the bottom plate is taken down.

Detailed Description

As can be seen from fig. 1, the top mold for prefabricating a reinforced concrete column disclosed in the present embodiment is used for prefabricating a column body with a rectangular cross section, and comprises a bottom plate 1, a first main rib positioning plate 2, a second main rib positioning plate 3 and a connecting frame 4.

As can be seen from fig. 2, the base plate 1 is a rectangular plate, and thick nuts LM are welded to four corners of the upper surface thereof. The plane size of bottom plate matches with the inner chamber size that cylinder steel reinforcement cage owner muscle encloses, and the periphery of bottom plate passes through the main muscle spacing promptly.

It can be seen from combining fig. 3 to 5 that first main muscle locating plate 2 and second main muscle locating plate 3 are the great strip shaped plate of length-width ratio, and their length is the same with bottom plate 1's length direction and width direction size respectively, and their length direction inboard has the U type groove that corresponds with main muscle position, and the notch width in U type groove matches with main muscle diameter, and first main

muscle locating plate

2 and 3 assemblages of second main muscle locating plate are around bottom plate 1.

The two end sections of the upper surfaces of the first main rib positioning plate 2 and the second main rib positioning plate 3 are symmetrically welded with thick nuts LM.

As can be seen from fig. 1 and 6, the connecting frame 4 is a # -shaped frame body, threaded holes are respectively formed in positions on the connecting frame corresponding to the thick nuts on the bottom plate 1 and the first and second main rib positioning plates, and the connecting frame is fixedly connected with the bottom plate and the main rib positioning plates through matched bolts.

When the column steel reinforcement cage is manufactured, the bottom plate is arranged in an inner cavity defined by the main reinforcements, and after the column steel reinforcement cage is manufactured, the steel reinforcement cage is hung in a mold, and then the main reinforcement positioning plate and the connecting frame are assembled.

When the column body is prefabricated and the mold is removed, the connecting frame, the connecting bolts between the bottom plate and the main rib positioning plates are taken down firstly, then the connecting frame is taken down along the direction of the main rib extending section, each main rib connecting plate is taken down along the length direction of the U-shaped groove, namely, the main ribs are taken down along the radial direction of the main ribs, and finally, the bottom plate is taken down.
