Embodiment Construction

[0033] The technical solution of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0034] Such as figure 1 Shown is the structural representation of the open box 5 of the present invention. The open box is made of glass fiber reinforced cement and is located under the laminated latticed steel bar 4 . The open box 5 is a GRC product, which plays the role of the side form of the cast-in-place reinforced concrete rib beam 1 during the concrete pouring process, and supports the lattice steel bar laminated plate 4 and the construction load. The bottom plate of the box body is exposed and used as the building roof , so the good durability of GRC products is closely related. The open box can be a single-section type, which forms a closed box body with the lattice steel laminated plate 4, or it can be a multi-section type, which forms a multi-section open box 5 through assembly, such as figure 2 shown. If it is a multi-section...

Abstract

The invention relates to a floor slab, in particular to an assembled monolithic concrete ribbed hollow floor slab with combination of prefabrication and casting in place and joint stress, which comprises reinforced concrete rib beams (1), a reinforced concrete overlapping layer (2) and assembled box dies (3); each reinforced concrete rib beam is formed by casting in place between the adjacent assembled box dies; the reinforced concrete overlapping layer is formed by casting in place above the assembled box dies; each assembled box die (3) comprises a lattice reinforced composite slab (4) and an open box (5), and each lattice reinforced composite slab is a top slab of the open box (5); and protruding steel bars (6) are arranged in the lattice reinforced composite slabs (4), the protruding steel bars protrude into the peripheral rib beams for anchoring, longitudinal stressed steel bars (11) in the rib beams are hooked, and the rib beams (1) and the lattice reinforced composite slabs (4)are jointly stressed. The structural height of the floor slab can be greatly reduced, and higher using space for a building can be provided under the situation of same storey height.

Description

technical field [0001] The invention relates to a floor slab, in particular to an assembled integral concrete dense-ribbed hollow-core floor slab combined with prefabrication and cast-in-place under common force. Background technique [0002] With the rapid development of my country's economic construction, reinforced concrete structures have been widely used in industrial and civil buildings, and have achieved good technical and economic results. Due to the requirements of high-rise, large space and earthquake resistance in buildings, many new structural systems with good technical and economic effects have been developed in recent years. [0003] In the past ten years, concrete ribbed hollow-core slabs have been widely used in construction projects in my country. Ribbed hollow-core floor slab refers to 1. The one-way or two-way type with rib spacing <= 1.5m is called dense-ribbed hollow-core floor slab; 2. It is suitable for public buildings with medium or large spans;...
