Problems solved by technology

In order to construct prefabricated paving panels with different shapes and sizes, the usual method is to order steel molds for prefabrication. Each set of steel molds can only construct prefabricated cement concrete slabs of one size and one shape. The processing cycle of the mold long, low reuse rate, and high input cost; if easy-to-process molds such as wooden molds are used, it is difficult to ensure the dimensional accuracy of prefabricated panels, which affects the on-site installation of prefabricated paving panels, and also wastes formwork materials
[0006] The traditional cement concrete slab mold is large in size, complicated to disassemble and assemble, and inconvenient to move and transport, so the concrete can only be poured at the same place; at the same time, the traditional mold can only pour one concrete slab, even if the slab size is smaller than the bottom formwork. Smaller, less efficient use of molds

Embodiment 1

[0057] To replace a non-rectangular cement concrete panel with unequal thickness, the damaged panel can be replaced quickly by using the prefabricated pavement repair technology. The plate is a special-shaped plate, and its plane dimensions are as follows Figure 4 As shown, according to the drill core results, the thickest part is 30cm, the thinnest part is 23cm, and the average thickness is 27.2cm.

[0058] The repair idea of ​​the plate is: use the above-mentioned prefabricated cement concrete paving slab mold to prefabricate a special-shaped plate similar to the target plate, prefabricate in the factory and reach the expected strength, and transport it to the site to replace the original plate to complete the repair. In the project, the method of leveling the base layer is used to make the thickness of the board consistent.

[0059] The plane size is reduced by 1cm from each side on the basis of the original plate size. In the actual construction process, cut along the s...

Abstract

The invention relates to the field of road engineering, in particular to a fabricated cement concrete pavement deck mold. The fabricated cement concrete pavement deck mold comprises a bottom formwork,the bottom formwork is provided with more than three side formworks, the side formworks extend along the upper surface of the bottom formwork, and the side formworks are connected in sequence to formupper open space with the side templates as the side walls and the bottom formwork as the bottom surface. Each side formwork is provided with one or more open and closed magnetic fasteners which arematched with material of the bottom formwork, the outer wall of each side formwork and the edge, corresponding to the outer wall, of the bottom template are connected by one or more telescopic fixed rods, one or more positioning frames are arranged above the upper open space, and the two ends of the positioning frames are detachably connected to the edges of the bottom formwork. According to the fabricated cement concrete pavement deck mold, the flatness of the panel surface is guaranteed, flexible dies are laid on the bottom formwork at the same time, a fine and complex surface structure of pavement decks is constructed, and the construction steps are simplified.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to an assembled cement concrete pavement mold. Background technique [0002] Prefabricated pavement technology is a rapid pavement construction technology. Its meaning is: to break the original pavement, transport the prefabricated pavement panels to the site for rapid assembly, and open traffic after completion. This technology can be applied to rapid new construction and rapid maintenance of road engineering, airport track engineering, and port pavement engineering. [0003] After the cement concrete paving slab is poured, its surface must be smoothed before the final setting of the concrete. When manual troweling is used, the labor intensity is high, and moisture, cement and fine sand will be brought to the concrete surface, so that the surface has higher drying shrinkage and lower strength than the lower concrete or mortar, which affects the overall surface of the paving panel. ...
