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

[0037] The present invention is realized in the following manner:

[0038] exist Figure 1-Figure 4 In the shown embodiment, a combined metal filling box with blocking paddles, the filling box (1) includes an upper assembly (2), a lower assembly (3), and a bracket (4), in a strip shape with a thickness of less than 1 mm Dense meshes (6) are formed on the metal sheet (5) by die-cutting, the short dimension of a single mesh (6) is ≥4mm and ≤12mm, and the long dimension of a single mesh (6) is ≥5mm and ≤15mm , the metal sheet that is punched out from the mesh (6) forms an outwardly warping slurry-resistance sheet (7), and one end of the slurry-resistance sheet (7) is still connected with the metal sheet (5) base material, and each sheet of metal The thin plate (5) has two bending lines (9), and the two ends of the metal thin plate (5) are bent 90° in the same direction along the bending lines (9) to form an upper assembly with a U-shaped structure with three surfaces ( 2) and t...

Abstract

The invention relates to a combined metal filling box with slurry blocking pieces and a manufacturing method of the combined metal filling box, and belongs to the field of general building structures. The filling box (1) comprises an upper assembly (2), a lower assembly (3) and supports (4); dense meshes (7) are formed in strip-shaped metal sheets (5) in a die-cutting forming manner; metal pieces die-cut out of the meshes (6) form the slurry blocking pieces (7) tilted outwards; two meander lines (9) are formed on each metal sheet; the two ends of the metal sheets are bent by 90 degrees in the same direction along the meander lines, respectively, to form the upper and lower assemblies of a U-shaped structure each with three planes; at least three supports are embedded in the upper and lower assemblies and locked to each other; two U-shaped abutting edges between the upper and lower assemblies are connected to form the filling box. The filling box is convenient to produce, transport and mount, and good in mechanical properties; besides, a hollow floor system formed by use of the filling box is good in reliability, earthquake resistance and cracking resistance.

Description

(1) Technical field [0001] The invention relates to a filling material in a reinforced concrete hollow floor structure, in particular to a combined metal filling box with blocking paddles 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 heavy weight of cement products, Xu Yan and others proposed Filling materials such as polystyrene foam; th...
