Abstract

The utility model relates to a building member, in particular to a light solid composite mandrel. Compared with the prior art, the composite mandrel consists of inner and outer three-layer structures, namely a polystyrene inner core layer, a fiberglass mesh fabric layer and a sizing outer layer from inside to outside respectively; an intermediate section of the composite mandrel is square; two ends of the composite mandrel are of a semi-arc shape; and a round hole which vertically penetrates is formed in the composite mandrel. The light solid composite mandrel disclosed by the utility model has the characteristics of favorable integral structure, high strength, no damage or crack, light dead weight and portability and rapidness in mounting.

Description

The compound core of light solid

Technical field

The utility model relates to building unit, the compound core of particularly a kind of light solid.

Background technology

The compound core of light solid is the filler in the cast-in-place concrete hollow building roof; What mostly adopted in the past is the thin-walled hollow filling product that cement is made; This product wall approaches hollow when making or transportation and installation cast, all to be prone to fragmentation no matter be; Particularly when pouring into a mould, installed and can not change owing to reinforcing bar after the fragmentation,, and increased the weight and the concrete consumption of floor so cast will be produced solid plate.

The utility model content

The purpose of the utility model is to provide a kind of light solid compound core.

The purpose of the utility model realizes through following approach: the compound core of a kind of light solid, and this compound core is made up of inside and outside three layer construction, is respectively polyphenyl inner core, fiberglass gridding cloth layer and slurry skin from inside to outside; Described compound core stage casing is square, and its two ends are half arc, and compound core is provided with and connects circular hole up and down.

Further, described Circularhole diameter is 100mm-150mm.

Compared with prior art, its advantage of the compound core of the utility model light solid is following:

1. the compound core one-shot forming of light solid overall structure is good, and intensity is high, nothing is damaged, free from flaw.

2. the compound core of light solid adopts be fire-retardant polyphenyl material all from heavy and light (weight of single product is generally about 2～15kg), more effectively reduced the floor deadweight.

3. the compound core of light solid is because himself is light, and light and fast is installed in the damage that is difficult for breaking, and has reduced the constructor, has improved construction speed and installation quality.

4. the compound core of light solid is owing to be solid with one-shot forming the back be installed and do not have damaged; Also can not smash up accidentally and form the solid concrete floor during concreting, the effective hollow rate when having guaranteed design and the deadweight of floor and load constant because of product breakage or vibration.

5. the both sides of the compound core of light solid are half camber, so more utilize concrete flowing to add that the centre has a steam vent can make floor slab bottoms more plain.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further explain:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model cross-sectional view;

Among the figure, polyphenyl inner core 1, fiberglass gridding cloth layer 2, slurry skin 3, circular hole 4, compound core 5.

The specific embodiment

Like Fig. 1, shown in Figure 2, the compound core of the utility model light solid, this compound core 5 is made up of inside and outside three layer construction, is respectively polyphenyl inner core 1, fiberglass gridding cloth layer 2 and slurry outer 3 from inside to outside; Described compound core 5 stage casings are square, and its two ends are half arc, and compound core 5 is provided with and connects diameter up and down is the circular hole 4 of 100mm-150mm.

Claims

1. compound core of light solid, it is characterized in that: this compound core (5) is made up of inside and outside three layer construction, is respectively polyphenyl inner core (1), fiberglass gridding cloth layer (2) and slurry outer (3) from inside to outside; Described compound core (5) stage casing is square, and its two ends are half arc, and compound core (5) is provided with and connects circular hole (4) up and down.

2. the compound core of light solid as claimed in claim 1 is characterized in that: described circular hole (4) diameter is 100mm-150mm.
