Description

Die carrier for pouring precast concrete lane plate

Technical Field

The utility model relates to the technical field of precast concrete construction, in particular to a formwork for precast concrete lane plate pouring.

Background

In the prior art, the underground garage ramp is basically cast in situ, the construction period is long, the underground garage ramp is easy to break after being used for a period of time, and the ramp vehicles are frequently in and out, so that the maintenance is inconvenient.

The prefabricated UHPC lane board, namely the prefabricated ultra-high performance concrete lane board, is prepared in the prior patent application of the inventor, so that the problems are solved well, and compared with an underground garage ramp cast in situ, the prefabricated UHPC lane board is paved and used immediately, the construction period is short, the construction efficiency is high, the prefabricated UHPC lane board is firm and durable, and the prefabricated UHPC lane board can be replaced locally even if a single place is damaged.

However, the prefabricated pouring is performed in a template placed on the ground, and the following defects still exist in the pouring process: 1. because the anti-skid tooth-rubbing face template is generally arranged on the bottom surface, the template needs to be turned 180 degrees during demoulding, the artificial turning is inconvenient, and the prefabricated UHPC lane board is easily damaged during the demoulding process of the artificial turning when the strength does not completely meet the quality requirement. 2. Because the rubber buffer strips in the width direction are to be pre-buried in the casting process of the prefabricated UHPC lane plate, the prior art template has no structure for compacting and limiting the pre-buried rubber buffer strips, thereby not only affecting the casting speed and efficiency, but also affecting the quality of the prefabricated UHPC lane plate.
