Sectional continuous floating-resistant cast-in-situ hollow slab

Abstract

The invention relates to a sectional continuous floating-resistant cast-in-situ hollow slab and a manufacturing method thereof and belongs to the field of construction of general buildings. The hollow slab comprises a filling body (1), a lower-layer reinforcing rib (3) and concrete (4), wherein the filling body (1) is positioned on the lower-layer reinforcing rib (3) of the filling body (1) and is permanently buried in the concrete (4); a main material of the filling body is a light-weight foaming material; a positioning cushion block (5) is arranged at the bottom of the filling body (1); floating-resistant iron wires (6) penetrate through a template (7); a fixing belt 98) is a nonmetal ribbon; the cross section of the fixing belt is in a flat shape; the fixing belt (8) bypasses the side and the upper part of the filling body and is connected with the floating-resistant iron wires (6); the filling body (1) is fixed in the floor slab by means of the floating-resistant iron wires (6) and the fixing belt (8). The sectional continuous floating-resistant cast-in-situ hollow slab disclosed by the invention has good economy and adaptability and a promoting action for the development of a building technology.

Description

(1) Technical field [0001] The invention relates to a cast-in-place reinforced concrete hollow floor, in particular to a piecewise continuous anti-floating cast-in-place hollow slab 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. In the field of hollow floors, there are various kinds of filling materials used, including high-strength cement (GRC), metal, rubber or plastic products, etc., but there are obvious defects in the use process. GRC is a brittle material. The core and box made of GRC have a large dead weight and a high water absorption rate. When subjected to impact loads and stacked heavy objects, they are easily broken. The cost of metal bellows is relatively high, and foot rubbing during construction can easily cause the bit...
