Composite fire bridge forming device

Abstract

The invention relates to a combined fireproof bridge span structure forming device, and belongs to the technical field of building laying devices. The combined fireproof bridge span structure forming device comprises a base, a bottom mold and an upper mold; the bottom mold is installed on the base, and is composed of a base plate and a plurality of component plates installed on the length edge of the base plat; the component plates are driven by a traction device, and can swing up and down around the base plate; the upper mold is positioned above the bottom mold, is driven by a lifting device to move up and down, and is matched with the bottom mold for use; when the upper mold moves downwards to be in contact with the bottom mold, materials on the bottom mold can form between the upper mold and the bottom mold. The combined fireproof bridge span structure forming device provided by the invention is adopted to enable a combined fireproof bridge span structure to be processed and formed, and has the advantages of high efficiency, uniform finished product quality, smooth surface and the like.

Description

Technical field [0001] The invention relates to a composite fireproof bridge frame forming device, belonging to the technical field of building laying devices. Background technique [0002] The fireproof bridge is a commonly used device for laying wires and cables in the installation of building electrical engineering. It is suitable for laying of power cables below 10KV, as well as indoor and outdoor overhead cable trenches and tunnels such as control cables and lighting wiring. It is mainly made of glass fiber reinforced materials and inorganic bonding. The fireproof principle is the non-combustibility of the substrate. The cable is installed in the bridge frame. When the cable is on fire, it can prevent the fire from spreading by not burning in the fire. [0003] The conventional processing of composite fireproof bridge frame is mostly manual. The wooden mold is used as a molding tool to first form the lower bottom surface of the bridge frame, and then two wooden molds are used...

AI Technical Summary

Problems solved by technology

[0003] The conventional processing of composite fireproof bridges is mostly manual, using wooden molds as molding tools, first forming the lower bottom of the bridge, and then extruding and curing materials such as glass fiber reinforced materials and inorganic adhesives on both sides of the lower bottom through two wooden molds , so as to form a U-shaped fireproof bridge. This kind of pure manual operation has many procedures, low production efficiency, and serious waste of raw materials; there are also hollow molds for bridge processing, and glass fiber reinforced materials and inorganic adhesives are fed into the mold. Then extrude, cool and solidify to form, but this method is prone to problems such as air bubbles in the formed product structure, uneven product material, etc., and after the product is formed, the product is bonded to the mold, and the product needs to be knocked out of the mold. The knocking process It is very easy to cause damage to the product, easy to produce defective products, the service life of the mold is short, and knocking will also cause deformation of the mold, which is not conducive to product quality control
