Embodiment Construction

[0021] Such as Figure 1 ~ Figure 3 Shown, the panel among the present invention is rectangular panel 1, is provided with frame 2 perpendicular to panel 1 board surface around panel 1 back side, frame 2 is a plate-like body, has some and other formwork connection usefulness on frame 2. The connecting holes 3 are rectangular through holes, and all the connecting holes 3 on the frame 2 on each side of the panel 1 are arranged in a straight line parallel to the long side of the frame 2 where they are located. A back rib is vertically arranged on the back of the panel 1, and the back rib is a plate-shaped body. The back rib is a keel supporting the panel 1 and is used to enhance the bending resistance of the panel 1. The back rib in the present invention includes a main rib 4 and a secondary rib 5, the upper edge of the main rib 4 reaches or approaches the plane where the top surface of the frame 2 is located, and the upper edge of the main rib in the present invention is in the m...

Abstract

The invention provides a plastic formwork for a building slab. The plastic formwork comprises a front plate and a frame, wherein the frame is vertical to the surface of the front plate; a plurality of connecting holes for connecting with other formworks are formed in the frame; a ribbed plate vertical to the surface of the front plate is arranged on the back of the front plate; the ribbed plate comprises a main ribbed plate and a secondary ribbed plate; the back of the front plate is divided into a plurality of rectangular partitioning areas, which are arranged longitudinally and transversely, by the main ribbed plate; the back of the front plate in the rectangular partitioning areas is partitioned into a plurality of longitudinal and transverse square blocks by the secondary ribbed plate in the rectangular partitioning area; plug-in type protective corners are respectively installed at four corners of the front plate. The plastic formwork overcomes the disadvantage that the whole plastic formwork is scraped because of the damage of the corners; the breaking rate of the plastic formwork for the slab is reduced; advantages of high-molecular material can be utilized and disadvantages are overcome; a plate design effectively matches with a support and reinforcing system, thus a scientific and effective formwork engineering system is finished.

Description

technical field [0001] The invention relates to building formwork in the technical field of building materials, in particular to a flat plastic formwork for building. Background technique [0002] The concrete pouring formwork used in construction projects mainly includes wood formwork, steel formwork and plastic formwork. The materials of wood formwork are generally pine and fir, but there are many problems in wood formwork, such as high wood consumption and low reuse rate. In order to save wood, wood formwork is seldom or hardly used in cast-in-place reinforced concrete structures. Steel formwork is generally made into shaped formwork and assembled into various shapes and sizes with connectors. It is suitable for various structural forms. It has high strength, high rigidity, flexible assembly, and easy assembly and disassembly. It is used in the construction of cast-in-place reinforced concrete structures. Wider, but the steel formwork has a large amount of investment and...
