Description

Formwork-making process with disassembling-free composite die block in concrete structure
Technical field
The present invention relates to a kind of concrete formwork support process, particularly a kind of formwork-making process with disassembling-free composite die block in concrete structure.
Background technology
Concreting needs formwork, formwork needs a large amount of templates, template is a kind of necessary constructional materials in concrete work, since oneth century, reasons such as (account for cost 30%) consumption is big because its cost height, perplexing people, China is used for timber that civil engineering consumes every year and reaches more than 1,000 ten thousand m always 3, by with steel for wood, can save 300 every year surplus ten thousand m 3, so huge material consumption is having a strong impact on ecological environment.China is the poor countries of the forest reserves, and forest land area accounts for about 4% of world's area of woods, and the existing forest amount of holding is 90.2 hundred million m 3, accounting for 3% of world's forest amount of holding, everyone occupies the forest amount of holding less than 9m per capita 3, for the world per capita the amount of holding 12%, timber annual production per capita has only 0.05m 3/ people reduces area of woods 14,800,000,000 m every year on average 2, China's timber yield is controlled at 6,000 ten thousand m 3, the actual demand amount surpasses 9,800 ten thousand m 3, account for 1/6 of national amount of wood and be used for infrastructure timber, this shows that the innovation of formwork support process is an arduousness and very long work.
Summary of the invention
The purpose of this invention is to provide a kind of formwork-making process with disassembling-free composite die block in concrete structure, composite shuttering and concrete will be connected as a single entity, after finishing concrete building, need not to dismantle template.
The present invention is achieved like this, and its processing step is: 1, system composite shuttering; 2, prop up the making of die component; 3, the installation of basic component and composite shuttering; 4, concreting; 5, form removal;
1, system composite shuttering:
(1) raw material takes by weighing: the weight ratio by 0.05～0.10 part of 1 part of cement, sand 1-2 part, reinforcing agent takes by weighing cement, sand, reinforcing agent respectively, and reinforcing agent is a rosin soap class cement intensifier;
(2) stir: the raw material that weighs up is poured into added water in the mixer and stir, make concrete;
(3) mould of arranging net: in the mould that is provided with the square frame rib, be distributed into one deck alkali-resistant glass fiber mesh cloth, the concrete that stirs is poured into;
(4) vibration moulding: with concrete jolt ramming, allow its natural coagulation moulding with bobbing machine;
(5) maintenance: once every 12 hours water seasonings;
(6) demoulding: after 1 day mould is removed, got product.
2, prop up the making of die component:
According to the needs of site operation, make the horizontal stupefied mould of all size, perpendicular stupefied mould, angle mould and bearing post with steel plate and channel-section steel.
3, the installation of basic component composite shuttering:
(1) draws cast-in-place single footing member and composite shuttering allocation plan by the construction drawing requirement, an establishment die component and composite shuttering batching inventory;
(2) reserve axis successively, definite horizontal absolute altitude and single line are carried out mark on the substrate bed course;
(3) the horizontal stupefied mould that will prepare is assembled into the foundation bottom mould by the good geometric form of axial line control, and angle mould is installed then successively, uses bolt;
(4) the installing and locating plate is used bolt;
(5) external mold around the basis is installed successively, template adopts the made composite shuttering of step (1), with thin wire composite shuttering is fixed.
4, press the good reinforcing bar of architectural drawing paper cloth after, get final product poured in place concrete.
5, form removal: (1) removes all bolts in the basis, with its classification vanning; (2) remove horizontal stupefied mould of basic steel and perpendicular stupefied mould, and its bundling is piled; (3) remove basic angle mould; Composite shuttering and concrete are connected as a single entity.
Advantage of the present invention is: 1, without timber, bamboo wood, economize on resources, preserve the ecological environment; 2, adopt shaped steel to make a mold materials, not fragile, life cycle is long, reduces cost; 3, highly versatile, the structure of building applicable to various concretes.
