Abstract

The utility model relates to a precast filling member for industrial and civil architecture dense rib hollow cavity floor slabs. The side wall and the upper and the lower bottoms are made into a fully-closed hollow polyhedral structure; a reinforcing rib is arranged in a die casing which is made of GRC, magnesium chloride GRC or haydite without sand. The mechanics performance of the member can satisfy various architectural design requirements, and the volume weight is decreased largely; the removal of the shuttering member need not, and the construction procedure is simplified; the suspended ceiling is not used, the construction progress is fast, and the construction cost is reduced.

Description

Shuttering member

The utility model relates to industry and the close a kind of prefabricated noggin piece that helps the cavity floor of civilian construction.

Reinforced concrete floor in the construction work, there are the prefabricated porous plate of employing or solid roof panel shaped structures and dense rib type floor slab structure not, by last, the porous plate that bottom surface and side constitute, solid roof panel cement prefabricated component is from great, the all essential lifting appliance that is equipped with in construction and process of assembling, cumbersome and labour intensity is big, present dense rib type floor, normally utilize detachable full-plastic formwork to carry out concrete pouring, treat again formwork to be removed after the concrete setting moulding, though the floor slab structure of moulding can alleviate deadweight like this, but also have the following disadvantages: 1, influence the floor processability behind the form removal, easily produce slight crack as floor top, the following of plate is not complete plane, and globality is poor; 2, need in some occasions that furred ceiling remedies, operation is many, troublesome poeration, cycle be long, take a lot of trouble during construction cost; 3, construction costs height: use though formwork is pulled down turnover, each every depreciation cost reaches more than 120 yuan, and can only use 4-6 time; Again furred ceiling, plaster or the like, it is bigger to pay wages.

The purpose of this utility model is to avoid weak point of the prior art, has been the formwork product of filling supporting member as internal mold both and provide a kind of.

Can take following technical scheme to realize purpose, around member, sidewall is set, make the sidewall and the upper and lower end constitute totally-enclosed empty stomach type polyhedral structure, establish ribs in the die housing; And they adopt rapid setting cement alkali resistant glass fiber (being called for short GRC) or magnesium chloride GRC or do not have the manufacturing of sand ﹠ ceramsite cement.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of structural representation of unidirectional shape rib shuttering member;

Fig. 2 is a kind of structural representation of cross rib shuttering member;

Fig. 3 is a kind of structural representation of groined type rib shuttering member.

Shuttering member constitutes totally-enclosed empty stomach polyhedral structure by upper base (1), go to the bottom (2), sidewall (3), establishes ribs (4) in the die housing.Whether the shape of polyhedral structure, length, size, thickness are reserved cabling or other and all can be selected as one sees fit with arranged form of hole and ribs (4) etc. on it.This shuttering member must adopt rapid setting cement alkali resistant glass fiber or magnesium chloride GRC composite material or not have the manufacturing of sand ﹠ ceramsite cement.Rapid setting cement in the rapid setting cement alkali resistant glass fiber can adopt sulphate aluminium cement or ferrous aluminate cement; In no sand ﹠ ceramsite cement, also can add steel fabric sheet.These materials can make that wall is thin, light weight, high strength and have the serial shuttering member of higher tension, resistance to compression, fracture resistance.GRC and magnesium chloride GRC material can be made into the shuttering member of thickness 6-15mm everywhere, and the no sand material of expecting cement and being added with steel fabric sheet of making pottery can be made into the shuttering member of thickness 25-35mm everywhere.

In the illustrated example, the ribs (4) in the die housing has unidirectional shape structure, decussate texture, groined type structure, can also be other arranged form, to increase the integrated support intensity of shuttering member.

During construction, by designing requirement, shuttering member is placed on the supporter of floor gap, reserve the certain clearance space between shuttering member, arrange reinforcing bar and pour into a mould with cement, shuttering member with reinforced concrete all very smooth whole floor slab structure of upper and lower surface.Shuttering member in floor be internal mold be again to fill supporting member, construction very saves trouble, easy.

The relative prior art of the technical program has following advantage:

1, the mould casing component mechanical property can satisfy various design of architecture requirements:

Analog vibration test: do not find seminess in 2.5 minutes;

Impact test: survey 15-30Kg/m with the rod hammer ²Do not find crackle and other anomaly;

Loading test: loading 299Kg/m ²Distortion 0.265mm;

Unit weight: four orifice plates are 2400Kg/m ³, and shuttering member is 500-800Kg/m ³, descend significantly.

2, need not the form removal member, kill two birds with one stone, globality is strong, strengthens support force; Simplify construction sequence, without furred ceiling, accelerating construction progress, also need not the collaborative construction of work posts such as electric welding, lifting.

3, reduce construction costs, reduce cost 3-4 doubly than overall plastic dismounting pattern shell, economic benefit is obvious.

Claims

1, a kind of shuttering member, it by upper base, go to the bottom and sidewall constitutes, it is characterized in that: have sidewall, the sidewall and the upper and lower end to constitute totally-enclosed empty stomach type polyhedral structure around it; Ribs is arranged in the die housing.

2, shuttering member as claimed in claim 1 is characterized in that: the ribs (4) in the die housing is unidirectional shape structure.

3, shuttering member as claimed in claim 1 is characterized in that: the ribs (4) in the die housing is a decussate texture.

4, shuttering member as claimed in claim 1 is characterized in that: the ribs (4) in the die housing is the groined type structure.
