Plastic box with thin wall

Abstract

A plastic thin-walled box, comprising an upper panel (1), surrounding side panels (2), and a lower bottom panel (3), wherein the upper panel (1), the surrounding side panels (2), and the lower bottom panel (3) enclose each other to form a seal The cavity thin-walled box is characterized in that the upper plate (1), the surrounding side plates (2), and the lower bottom plate (3) are all assembled from plastic plates (4), and the joint parts are composed of connectors (5 ) are connected as a whole, and the inner side of the plastic sheet (4) is provided with reinforcing ribs (6). In this way, the space occupied by each part during transportation is small, the quantity of each transportation is large, the transportation cost is low, and the transportation is convenient, which correspondingly reduces the production cost of plastic thin-walled boxes and the construction cost of cast-in-place reinforced concrete hollow slabs; at the same time, It greatly improves the rigidity and strength of the plastic slab, making the plastic slab not easy to deform. It is suitable for hollow slabs, floors, roofs, foundation slabs, walls and hollow bridges of various cast-in-place reinforced concrete or prestressed reinforced concrete. , especially suitable for use in hollow beamless floors.

Description

(1) Technical field [0001] The invention relates to a plastic thin-wall box. (2) Background technology [0002] At present, in the prior art, the hole-forming member of the cast-in-place reinforced concrete hollow slab is a permanent mandrel, such as paper tubes, plastic tubes, metal bellows, hollow form shells, and lightweight materials for mandrels. These tubular mandrels or hollow components are mainly considered to evacuate the concrete and reduce the weight of the hollow slab. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity. Another example is that the application number applied by the applicant on November 23,...

Problems solved by technology

However, this kind of thin-walled box formwork member, as an integral thin-walled box member, takes up a lot of space during transportation, the quantity of each transportation is small, and the transportation cost is high, which undoubtedly increases the production cost of the thin-walled box and the cast-in-place reinforced concrete. Construction cost of hollow core slabs
