High-strength non-dismantling formwork and manufacturing method thereof

Abstract

The invention discloses a high-strength non-dismantling formwork and a manufacturing method thereof. The high-strength non-dismantling formwork is formed by compositing inorganic hardening cement fiber boards and a steel wire mesh, and the steel wire mesh is located between the two inorganic hardening cement fiber boards; and the steel wire mesh is composed of a steel wire net and a steel belt, and the steel belt is welded to the surface of the steel wire net in a flat laid mode. The manufacturing method comprises the steps that production devices are selected, and all the devices are connected in a roller conveying mode; the manufactured wet inorganic hardening cement fiber boards and the steel wire mesh move towards a formwork laminating worktable, and formwork blanks are laminated through a formwork laminating manipulator; the formwork blanks enter a formwork pressing device to be pressed at the low pressure to form composite boards in a wet blank state; the composite boards in thewet blank state enter a formwork edge-cutting device to be subjected to raw edge cutting and thus turned into formwork master batches; the formwork master batches enter a formwork pressure-maintainingdevice to be pressed at the high pressure, pressing force is not lower than 5000 tons, and sufficient compositing between all layers of the formwork is ensured; and the pressure-maintained formwork master batches enter a formwork cutting device to be cut in the specified size, and thus a finished high-strength non-dismantling formwork product is manufactured.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a high-strength demolition-free formwork and a manufacturing method thereof. Background technique [0002] At present, in construction engineering, the formwork used for shaping the casting can be divided into two categories. The first type is a detachable formwork that can be reused, and the second type is a non-demolition formwork. [0003] For the non-demolition formwork, it is usually used in light steel keel construction or cast-in-place walls with light steel keel structure. Demolition, and then pouring / filling lightweight thermal insulation materials in the non-demolition formwork to form a wall structure of keel + pouring / filling + non-demolition formwork. [0004] At this stage, the common non-demolition formwork on the market mainly includes inorganic plates such as cement pressure board, silicon-calcium board, paper-faced stone board, part...

AI Technical Summary

Problems solved by technology

[0004] At this stage, the common non-demolition formwork on the market mainly includes inorganic plates such as cement pressure board, silicon-calcium board, paper-faced stone board, particle board, and ceramic board. Self-tapping screws are connected to the keel of the wall. Due to the low strength of these non-demolition formwork, it is easy to deform, and the non-demolition formwork is also prone to bulge when the wall is poured; in addition, the tensile performance of these non-demolition formwork is relatively low Poor, even if it is connected to the wall keel by rivets or self-tapping screws, the connection firmness is not high. Affect the stability and service life of the wall

[0005] For reinforced concrete buildings, at present, only detachable formwork can be used instead of non-demolition formwork. Because the strength of the existing non-demolition formwork is too low, it is difficult to meet the technical requirements of reinforced concrete buildings before and after pouring and setting
