Plastic thin wall caddy

Abstract

A plastic thin wall caddy includes upper plate (1), surrounding arthropleure (2) and infrabasal plate (3) with the upper plate (1), surrounding arthropleure (2) and infrabasal plate (3) forming an enclosed hollow space thin wall caddy by the (1), (2) and (3) mutually enclosing each other, which is characterized in that the aforementioned upper plate (1), surrounding arthropleure (2) and infrabasalplate (3) are all pieced by plastic plate tablet (4), the piecing sections joint into a whole through connecting components, there sets the inner supporting wall component (6) for supporting the inner wall of thin wall caddy and sealing wall component (7) of sealing caddy terminal wall at no fewer than one piece of plastic plate tablets (4), the inner supporting wall components (6) on the plasticplate tablet (4) and sealing wall component (7) of sealing caddy terminal wall constitute the mother trough (8) on the plastic plate tablet (4), the end of the plastic plate tablet (4) inserts into the mother trough (8), and then seals the thin wall caddy in the end, there is supporting wall conical supporting piece (9) in the mother trough (8) on the plastic plate tablet (4), in the hollow spaceof thin wall caddy there sets at least one kind of stakes ring frame (10), supporting ring frame (11), stakes (12) or facing bar (13), and connects with the inner wall of plastic plate tablet (4) ofthin wall caddy. The invention is suitable for various hollow slabs, hollow floor, floor cover, foundation bedplate, wall and open spandrel bridge of cast-in-situ reinforced concrete or prestressed reinforced concrete, especially suitable for hollow mushroom floor.

Description

[0001] This application is a divisional application for an invention patent application with an application date of February 7, 2005, an application number of 2005100522712, and the title of "a plastic thin-walled box". (1) Technical field [0002] The present invention relates to a plastic thin-walled box. (2) Background technology [0003] At present, in the prior art, the cast-in-place reinforced concrete hollow plate hole-forming members are permanent core molds, such as paper tubes, plastic pipes, metal bellows, hollow mold shells, and lightweight materials for core molds. These tubular core molds or hollow members mainly consider evacuated concrete to reduce the weight of hollow panels. For example, the patent number ZL99249798.1 filed by the applicant on November 29, 1999 and the utility model patent titled "Fiber-reinforced thin-walled member for reinforced concrete filling" discloses a thin-walled formwork member, including an upper plate, The surrounding side wall...

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
