A prefabricated component for lightweight panels

Abstract

A prefabricated component for a lightweight panel, characterized in that at least two or more lightweight blocks (3) are arranged at intervals in the long groove of the elongated slotted plate, and the interval between the lightweight blocks (3) constitutes the same Orthogonal or / and oblique inner rib empty slots (4) with long slots, light block (3) with a cover plate (5) or slot-shaped cover (6) connecting the side panels (2) as a whole, the cover plate (5) or trough covers (6) are arranged at intervals, and the interval between the cover plate (5) or the trough cover (6) is the same as that of the lightweight block (3), and the intersecting part with the side plate (2) There are longitudinal prestressed or non-prestressed steel bars or steel strands (7) in the bottom plate (1), and the connecting bridge (9) is a lightweight block connecting bridge or a stiffened connecting bridge. The light block connecting bridge (9) or / and the stiffening connecting bridge (9) are layered composite connecting bridges.

Description

[0001] This application is a divisional application for an invention patent application whose application date is November 23, 2004, the application number is 2004100928929, and the title is "a kind of prefabricated component for lightweight panels". (1) Technical field [0002] The invention relates to a prefabricated component for a lightweight board. (2) Background technology [0003] The lightweight slabs are assembled with ribbed reinforced concrete prefabricated components, which can bear two-way load, do not need on-site formwork, and are low in cost, easy to hoist and transport. The ribbed prefabricated member includes a long strip bottom plate and a long strip side plate. The side plate and the bottom plate are connected as a whole to form a T-shaped or long groove-shaped member. Usually the length of the side plate of this kind of prefabricated component is the same as the length of the bottom plate. When the prefabricated component is assembled to form a lightweight sla...

AI Technical Summary

Problems solved by technology

Usually the length of the side slab of this prefabricated component is the same as the length of the bottom slab. When this prefabricated component is assembled to form a lightweight slab that bears two-way loads, the cast-in-place concrete cannot pass through the side slab and cannot form a connected intersecting slab with the side slab. In-situ concrete ribs, at the same time, in the direction perpendicular to the side plate, various pipeline layouts need to be drilled and threaded on site, which not only wastes concrete materials, but also wastes man-hours. Moreover, after cast-in-place concrete, the assembled lightweight panels are solid. Concrete consumes a lot of material, and the lightweight slab is heavy, which is not suitable for large-span pouring. Therefore, it is urgent to develop a new type of prefabricated component for lightweight slabs.
