Embodiment Construction

[0008] Attached below figure 1 Give an example: as figure 1 As shown, the large-thickness hollow floor of the thin-walled internal formwork is a double-layer reinforced structure, and the core tube 1 in the shape of a fully enclosed circular tube with a diameter of 450 cm is embedded in the middle of the concrete structure to form a hollow structure and become a permanent core. mold. The upper and lower sides of the core pipe 1 are provided with reinforcement meshes 2 and 3 respectively. Each core tube 1 is tightly wound with a pressure tube steel bar 4 , and the two ends of the pressure tube steel bar 4 are fixedly connected with the lower reinforcement mesh 3 . A row of vertical anti-floating reinforcing bars 5 is arranged every two core tubes 1, and the upper and lower ends of the anti-floating reinforcing bars 5 are fixedly connected with the upper and lower reinforcing meshes 2 and 3 respectively.

[0009] like figure 1 As shown, pouring concrete 6 is filled between t...

Abstract

The invention discloses a thin-wall internal-mould large-thickness hollow floor plate comprising a layer of totally-closed core pipes in circular pipe shapes, reinforcing meshes and pouring concrete, wherein the reinforcing meshes are respectively arranged above and below the layer of core pipes; a pressure pipe reinforcing bar is tightly close to and surrounds each core pipe, and a row of vertical anti-floating reinforcing bars are arranged at intervals of every 2-4 core pipes; and the pouring concrete is filled among the core pipes, the reinforcing meshes and the pressure pipe reinforcing bars and on the upper surface of the upper reinforcing mesh. The thin-wall internal-mould large-thickness hollow floor plate is in a double-layer reinforcing bar structure, the core pipes are positioned in the middle of the pouring concrete to form a hollow structure so as to become a permanent core mould, and the problems of fixation and floating of the core pipes in the concrete pouring process are solved through the structure. The invention has the advantages of fast construction, convenient installation, heat insulation and good sound insulation performance, can effectively reduce the self weight, correspondingly decreases girders, columns and walls which support the floor plate and foundation loads and greatly reduces the quantity of reinforcing bars as structural members.

Description

technical field [0001] The invention relates to a hollow floor slab, in particular to a hollow floor slab with a thin-walled inner mold and a large thickness. Background technique [0002] With the continuous development of construction technology, new technology and new technology are constantly adapting to the requirements of large span, large space, flexible separation and earthquake resistance of construction houses. The cast-in-place concrete hollow-core slab is one of the technologies. The construction technology of the large-diameter single-pipe hollow floor slab is novel and simple, the construction speed is fast, and the thermal insulation and sound insulation performance is good, which can effectively reduce the structural weight and weaken the earthquake force. Compared with the ordinary concrete floor structure system, the cast-in-place hollow concrete beamless floor structure system can reduce the total construction cost according to the span and load, and the ...
