Problems solved by technology

[0008] In the existing hollow floor technology, there are problems such as the large buoyancy of the filling material that makes construction difficult, or the integrity of the filling material is poor, the stiffness is small, the quality of concrete pouring around the filling material cannot be effectively guaranteed, or the transportation cost is too high. The purpose of the present invention is to Provide a combined metal stuffing box with blocking pad

Embodiment Construction

[0035] The present invention is realized in the following manner:

[0036] exist Figure 1-Figure 5 In the shown embodiment, a gas-permeable combined filling box formed by thin metal plates, the filling box (1) includes an upper assembly (2), a lower assembly (3), a stiffener (4), and a leakage cylinder (5) , forming a dense mesh (7) on a strip metal sheet (6) with a thickness of less than 1mm by die-cutting, there are 2 bending lines (8) on each sheet metal sheet, and 2 lines of bending lines (8) on the sheet metal sheet A slurry leakage hole (9) with a size ≥ 50 mm and ≤ 150 mm is opened between the bending lines and in the center of the width range of the metal sheet, and the two ends of the metal sheet are bent 90° in the same direction along the bending line to form a three-dimensional The U-shaped upper and lower components of the two-sided structure are installed in the upper and lower components with leaking tubes and at least 2 stiffeners in each direction. The posit...

Abstract

The invention relates to a breathable combined filling box formed by metal sheets and a manufacturing method thereof, belonging to the field of general building construction. The stuffing box (1) includes an upper assembly (2), a lower assembly (3), a stiffener (4), and a leaking tank (5), and a dense The mesh (7) has 2 bending lines (8) on each metal sheet, and a slurry leakage hole (9) is opened in the central part of the metal sheet, and the metal sheet is bent into a U-shaped structure upper assembly and a lower assembly, Install the leakage tube and the stiffener in the upper and lower components, the position of the leakage tube and the leakage hole coincides with each other, connect the two U-shaped butt edges between the upper and lower components that are buckled together to form a stuffing box. The stuffing box of the present invention is very convenient for production, transportation and installation, and has good mechanical properties, and the hollow floor formed by this product is also good in reliability, shock resistance and crack resistance.

Description

(1) Technical field [0001] The invention relates to a filling material in a reinforced concrete hollow floor structure, in particular to a breathable combined filling box formed by a thin metal plate and a manufacturing method thereof, belonging to the field of general building construction. (2) Background technology [0002] In the field of construction, with the increasing number of long-span concrete structures, more and more floor slabs adopt hollow-core floor structure technology. Replacing part of the concrete with lightweight filling materials will basically not affect the mechanical performance of the structure, but it can greatly reduce the self-weight of the structure. [0003] In the early hollow floor, scholars represented by Qiu Zeyou and Wang Benmiao proposed to use high-strength cement to make cement pipes and cement boxes as filling materials; later, in view of the importance of cement products, I once proposed polystyrene foam A class of filling materials; ...
