Abstract

The utility model discloses a combined building cover plate with hidden concrete ribs, which is composed of thin prefabricated slabs, mould casings, hidden ribs and an upper slab, wherein the thin prefabricated slabs are arranged horizontally at intervals, the mould casings are fixed to the thin prefabricated slabs, the hidden ribs are arranged between the adjacent thin prefabricated slabs or the adjacent mould casings and the upper slab is covered on the mould casings and is connected with the hidden ribs into a whole. The utility model has the advantages of favorable integrity, shock resistance, no crack, no water seepage, less use of mould plates because of only supporting the mould plates in the position of the hidden ribs in construction, low cost and high building speed.

Description

Combination concrete hidden rib floor structure

The utility model relates to a kind of building unit, particularly a kind of floor structure.

At present, brick mixes the most of precast hollow slab that adopts of building of method structure and frame construction as floor structure, it is fast that this floor structure has speed of application, advantages such as cost is low, but, only use cement blind owing to firmly do not link between adjacent two precast hollow slabs, thereby not only globality is poor, be unfavorable for antidetonation, and slit cracking, infiltration often occur, put to no little inconvenience and psychological pressure to resident family.For addressing the above problem, a lot of building have adopted the method for Cast-in-place concrete floor (solid, hollow).Though the Cast-in-place concrete floor has solved antidetonation and problems of crack, when construction, to use a large amount of templates, like this, not only increased expense, and the speed of application that slowed down, prolonged the duration.

The utility model purpose provides a kind of overall performance that had both had cast in site floor, combination concrete hidden rib floor structure that again can rapid construction.

The purpose of this utility model is realized by following technical scheme:

A kind of combination concrete hidden rib floor structure, it is by prefabricated plate, and formwork, dark rib, upper plate are formed, each prefabricated plate is horizontal positioned at interval, is fixed with formwork on prefabricated plate, is provided with dark rib between contiguous prefabricated thin plate or the formwork, upper plate covers on the formwork, and connects as one with dark rib.

Above-mentioned floor structure, the edge of described prefabricated plate is provided with outwardly directed embedded bar.

Above-mentioned floor structure, described dark rib and upper plate link into an integrated entity with the concrete cast.

Adopt the floor structure of this structure, the thin plate of lower floor is connected to each other, pour into an integrated entity with dark rib and upper plate again, therefore have good globality and shock resistance, also defectives such as crack, infiltration can not occur, and when cast only needs reduce the use amount of template greatly at dark flank position support shuttering, reduce expense, accelerated speed of application.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a structural profile schematic diagram of the present utility model;

Fig. 2 is an overall schematic of the present utility model;

Fig. 3 is the utility model thin plate schematic diagram;

Fig. 4 is the utility model formwork schematic diagram.

By seeing among Fig. 1, this combination concrete hidden rib floor structure divides three layers, bottom is a prefabricated plate 1, its thickness is greater than 20mm, aspect ratio is 1: 1-5: 1, and the polylith prefabricated plate is evenly distributed at certain intervals, between adjacent two prefabricated plates certain interval is arranged, reinforcing bar, steel wire or net sheet etc. are arranged as skeleton, to guarantee its intensity in the prefabricated plate.Outward flange is provided with outwardly directed embedded bar 5 around prefabricated plate 1, and the embedded bar of contiguous prefabricated thin plate can be connected.Skeletons such as reinforcing bar, steel wire or net sheet in the prefabricated plate can be connected as a single entity with embedded bar 5.Middle level on the prefabricated plate is a formwork 2, formwork can be solid, also hollow, its available plant straw, glass fiber reinforced plastic, sheet iron plate, light materials such as glass fibre cement are made, its profile can be made shapes such as rectangle, circle, polygon according to designing requirement, can play sound insulation, heat insulation effect.Formwork 2 is fixed on the prefabricated plate 1, is provided with dark rib 3 between the adjacent prefabricated plate 1 and between the adjacent formwork 2.The superiors at floor structure are upper plates 4, and upper plate forms by concrete is integrated poured, and after integrated poured, prefabricated plate, dark rib, upper plate become a reinforced concrete integral body.Have good globality, shock resistance, do not ftracture, do not seep water, its formwork can play good insulation, soundproof effect.

Sequence of construction: prefabricated plate on following in the position of designing dark rib, on thin plate, to put formwork, and the embedded bar of adjacent prefabricated plate is connected, connection can be adopted welding, colligation, modes such as overlap joint.Then formwork is fixed on the thin plate, carries out the concrete cast at last, finish combination concrete hidden rib floor structure.

Be the data of an embodiment below:

Prefabricated plate thickness 30mm, length * wide 1200mm * 1000mm;

Formwork thickness 100mm;

Dark rib width 200mm;

Last plate thickness 70mm.
