Abstract

The invention relates to a concrete component, and in particular relates to a steel rib glass concrete special-shaped section column used in civil engineering. The section of the special-shaped column is of T, L and crossed shapes, the steel ribs are formed by soldering steel plates, and the steel ribs, reinforcing steel bars and glass concrete form the steel rib glass concrete special-shaped section column, wherein concrete comprises glass fragments serving as aggregates; the glass concrete comprises coarse glass aggregates with grain diameter of 5-30mm, and fine glass aggregates with grain diameter of 0.1-3mm; according to the volume of each cubic meter of the glass concrete, 300-1,500kg of the coarse aggregate glass, 300-1,500kg of the fine aggregate glass, 400-600kg of the cement and 150-300kg of water are mixed sufficiently. The steel rib glass concrete special-shaped column is a main component of a building frame structure in high-rise buildings, and has the characteristics of high bearing capacity, high rigidity, light weight, good plasticity and toughness, good impact and fatigue resistance, excellent earthquake resistance and the like.

Description

Reinforcing bar glascrete odd-shaped cross section post

Technical field

The present invention relates to a kind of concrete component, particularly relate to a kind of reinforcing bar glascrete odd-shaped cross section post for civil engineering, is a kind of novel steel reinforced concrete coupled column.

Background technology

At present, the frame column as the main member of frame construction, is generally common reinforced concrete post.But owing to cannot solving the thickness that is often greater than body of wall due to the sectional dimension of frame column, in use, the indoor pillar that there will be is partly given prominence to the phenomenon of body of wall, thereby has affected indoor space and use.

In order to address this problem, there is the form of structure of shaped rc columns.For reinforced concrete special-shape column structure, mainly contain T, L, cross, scholar both domestic and external has carried out extensive, deep research.Its theory basically forms, and writing of the local rules that the provinces and cities such as Tianjin, Shenyang, Guangdong, Shanxi have completed, and guides in engineering practice, and building area reaches number with ten million square metre.

But, also find under study for action: the ductility ratio ordinary rectangular post of shaped rc columns poor.Hetermorphiscal column is due to the existence of many limbs, and its centre of shear does not often overlap with the cross section centre of form, and under stress, each limb produces warped normal strain and shear stress.Due to shear stress, make post limb concrete occur crack prior to ordinary rectangular post, cause hetermorphiscal column fragility obvious, the deformability of hetermorphiscal column is reduced than ordinary rectangular post.

In order to address this problem, many experts once proposed many suggestions and scheme.As I once applied for patent: steel pipe concrete profiled pile, special-shaped carbon fiber reinforced plastic steel tube concrete core pillar, a kind of steel-reinforced concrete core column and preparation method thereof etc.Although these technology can address this problem to a certain extent, also not bery perfect, especially concrete materials, are unfavorable for environmental protection and energy-conservation.

Have in recent years a large amount of scrap glasses to produce, scrap glass is one way of life rubbish and industrial waste.In scrap glass, mostly adopt the methods such as landfill to process, take valuable land resources, to environment, cause serious burden, the recycling that therefore improves a large amount of scrap glasses becomes the problem of current key.In addition, along with the continuous cracking of sand and stone resources, natural concrete aggregate resource is day by day exhausted, and has brought serious harm to environment.Therefore using scrap glass, as gathering materials to come concrete batching, be, an approach well overcoming the above problems.

Therefore, seminar's imagination, using waste gas glass as concrete aggregate, for building, and forms reinforcing bar glascrete odd-shaped cross section post, the good method of can yet be regarded as.

Summary of the invention

The object of this invention is to provide a kind of reinforcing bar glascrete odd-shaped cross section post, by glascrete, form a whole.

The object of the invention is to be achieved through the following technical solutions: by reinforcing bar, reinforcing bar and glascrete, formed, by glascrete, form a whole, the section form of odd-shaped cross section post is T, L, cross, reinforcing bar is formed by Plate Welding, it is characterized in that: by reinforcing bar, reinforcing bar and glascrete, form reinforcing bar glascrete odd-shaped cross section post, in its concrete, contain the glass fragment that serves as aggregate; Described glascrete comprise particle diameter at the raw glass aggregate of 5mm～30mm and particle diameter the thin glass aggregate at 0.1mm～3mm; According to every cubic metre of glascrete volume, coarse aggregate glass weight 300kg～1500kg, fines glass weight 300kg～1500kg, cement 400 kg～600 kg, the ratio of water 150 kg～300 kg fully stirs; Described glascrete glass comprises simple substance glass, organic glass and unorganic glass; The reinforcing bar of reinforcing bar glascrete odd-shaped cross section post is wrapped up by reinforcing bar glascrete.

Advantage of the present invention and effect are:

1. make full use of waste gas glass, accomplish twice laid, energy conservation, environmental protection;

2. reinforcing bar is positioned at the inside of direction concrete crossover sites in length and breadth, can be fire-resistant, corrosion-resistant;

3. the reinforcing bar of can first constructing, forms cast glass concrete after skeleton, thereby forms superposed column;

4. due to the existence of reinforcing bar, improve the ductility of post, improved the bearing capacity of post, be beneficial to earthquake zone seismic design.

Accompanying drawing explanation

Fig. 1 is that cross section is the reinforcing bar glascrete odd-shaped cross section post schematic diagram of " ten " character form structure.

Fig. 2 is that cross section is the reinforcing bar glascrete odd-shaped cross section post schematic diagram of " L " character form structure.

Fig. 3 is that cross section is the reinforcing bar glascrete odd-shaped cross section post schematic diagram of " T " character form structure.

Reinforcing bar, reinforcing bar and glascrete, consist of, wherein glascrete wraps up reinforcing bar, makes reinforcing bar be positioned at the reinforcing bar glascrete of direction in length and breadth.In figure, 1 is reinforcing bar, and 2 is reinforcing bar glascrete.

The specific embodiment

1. according to the rules Plate Welding is become to reinforcing bar skeleton;

2. reinforcing bar is erected, and keep vertical or certain angle;

3. assembling reinforcement skeleton;

4. at reinforcing bar lateral branch masterplate;

5. make particle diameter at 5mm～30mm and particle diameter the glass fragment at 0.1mm～3mm, respectively as coarse aggregate in glascrete and fines;

6. according to every cubic metre of glascrete volume, coarse aggregate glass weight 300kg～1500kg, fines glass weight 300kg～1500kg, cement 400 kg～600 kg, the ratio of water 150 kg～300 kg fully stirs;
