Method for continuously producing fibre reinforced synthetic resin lattice body

Abstract

To provide a method for the continuous production of a lattice-shaped body made of a fiber-reinforced synthetic resin which can be applied to a material unable to be cured by light such as carbon fibers, and can sufficiently press-bond even a reinforcer with fine meshes without using a large amount of a resin. Layers comprising groups of linear longitudinal members which are formed on an advancing carrier by arranging the longitudinal members of continuous fibers impregnated with the uncured resin in parallel, in the advance direction of the carrier at intervals and layers comprising linear lateral members, which are formed by arranging the lateral members of continuous fibers impregnated with the uncured resin perpendicularly to the advance direction of the carrier at intervals. The lateral members are folded in a U-shape at both side ends of the carrier are laid alternately to overlap each other to form at least three layers. In this way, the lattice-shaped body in which both members are laminated in an intersection part in which the groups of the longitudinal members and the lateral members are crossed. Next, by pressing the lattice-shaped body from above by a press means, with the groups of the longitudinal members and the lateral members press-bonded in the intersection part, the uncured resin material in the lattice-shaped body is heat-cured.

Description

technical field [0001] The present invention relates to a method for continuously manufacturing a fiber-reinforced synthetic resin grid-like body used as a concrete reinforcement material in the field of civil engineering and construction. Background technique [0002] As a reinforcing material used for embedding concrete structures in the field of civil engineering and construction, a fiber-reinforced synthetic resin grid-like body as described in Japanese Patent No. 62-153449 is currently used. Its structure is as follows: the resin-impregnated materials arranged side by side The multi-strand fibers are combined into fiber bundles, and a grid-like body is formed by repeated crossing. At the intersection of the grid, a cross-sectional structure in which fiber bundles extending in one direction and fiber bundles extending in the other direction are laminated to each other is formed. [0003] At present, this kind of fiber-reinforced synthetic resin grid-like body is first fo...

Problems solved by technology

However, it is difficult for this mechanism to adjust the extrusion force according to the grid-like body, and the frictional resistance increases when the grid-like body contacts the steel and belt conveyor as the crimping device, limiting the travel speed of the grid-like body

In addition, if the travel speed fluctuates, the quality of the mesh may decrease

In addition, due to the friction between the grid-like body, the resin may be detached from the linear parts connected by the crimping device, and the resin will cause the quality of the grid-like body to deteriorate, and the more serious problem is that the grid-like body itself may be damaged shape change

In addition to this, since the machinery is always exposed to the heating environment, the devices used in this manufacturing process may also malfunction, as the mechanism blocks the thermal radiation, which may also prevent adequate heating of the grid-like body
