At least provided with one layer of reinforced mesh 6 in siphonal lobe wall 1；Several are equipped on siphonal lobe wall 1 to be through in internal lobe wall 3
The through-wall bolt hole 8 of side；It is connected in the lower end of the bar frame 4 of internal lobe wall 3 and is equipped with a reinforcing steel bar connecting sleeve tube 7.
The fiber volume rate of the steel fiber reinforced concrete (including endpoint value) between 1% -2%.
28 days compression strength of the concrete are 128%, mainly to fully ensure that steel fibre tensile strength and concrete
Intensity is adapted.
The steel fiber reinforced concrete is made of the component of following mass fraction: 818 parts of sand, 500 parts of cementitious material, stone 887
Part, 7.5 parts of additive, 7.5 parts of defoaming agent, 10 parts of steel fibre；500 parts of cementitious materials are by 350 parts of cement, flyash 100
Part, 50 parts of miberal powder compositions；The cement uses P.O42.5 cement；Flyash is II grade of flyash；Miberal powder is S95 grades；Sand uses
Optional stage matches the middle sand in IIth area；Stone uses 5-10mm Stone；Additive uses high performance water reducing agent of polyocarboxy acid, water-reducing rate
It is required that being 35%.
A kind of production and construction method of the heat insulation integrated overlapping wall of steel fibre, it is same as Example 1.
Test example:
Shandong building constructor carries out after production steel fiber reinforced concrete in the manner described above and carries out detail statistics production
Its properties is counted after 1000 steel fiber reinforced concretes, is obtained such as the steel fibre in the application in the following table 1
The comparison of the normal concrete various performance parameters of concrete and existing product.
The performance parameter table of 1 steel fiber reinforced concrete of table
| Product preparation method | Resistance to compression |
| Existing method | 40MPa |
| Embodiment 1 | 43MPa |
| Embodiment 2 | 47MPa |
| Embodiment 3 | 50MPa |
It can thus be seen that this heat preservation overlapping exterior wall has superior mechanical property: higher compression strength improves concrete
Performance, reduce and prevented siphonal lobe layer concrete and the phenomenon that cracking and collapsing angle occur, not only improve presentation quality, while can
Reduce the repairing frequency in later period and scraps probability.
Above-mentioned specific embodiment cannot function as limiting the scope of the invention, for the technology people of the art
For member, any alternate modification or transformation made to embodiment of the present invention are fallen within the scope of protection of the present invention.
Place is not described in detail by the present invention, is the well-known technique of those skilled in the art of the present technique.
