The present invention is suitable for the gymnasium of Shucheng County, Anhui Province sports center construction project first stage of the project and the whole people are good for
Good application has been obtained in body shop, achieves certain economic interests；Shucheng County, Anhui Province sports center construction project
First stage of the project is located to the west of Wan Folu, to the north of seven roads Men Yan, is made of that (one is stadium, two shops are body " one, two shops "
Educate shop and nationwide fitness programs shop)；Total land area 320216 ㎡, 84495 ㎡ of overall floorage；2 layers on the ground of gymnasium, underground part
1 layer, a circle is 24 groups of reinforced concrete combination batter posts on the outside of grandstand layer, 3 pillars of every group of batter post, wherein 2 are two-way to incline
Tiltedly (batter post sectional dimension 400mm × 800mm, 66.1 ° of circumferential tilt angle, 56.2 ° of radial angular orientation), 1 be unidirectionally to incline
Tiltedly (batter post sectional dimension 700mm × 800mm, 72.8 ° of circumferential tilt angle)；5 layers on the ground of nationwide fitness programs shop, 2 layers of underground part,
Position shares four armored concrete batter posts (batter post sectional dimension 600mm × 600mm, tilt angle among its north and south side
82.87 °)；In this project, the molding of reinforced concrete combination batter post cast-in-place structural preferably, has obtained designing unit, construction unit
Favorable comment consistent with supervisor, bring economic benefit mainly consider that the tie that batter post is reinforced is replaced using finished product reinforcing member
Conventional steel fastener, taper pile shuttering are decorated using mirror surface formwork, and when finishing exempts from bring benefit of plastering.
(1) batter post, which is reinforced, replaces conventional steel fastener using finished product reinforcing member
It is reinforced according to conventional steel fastener, steel tube fastener needs additional increase to support, and every group batter post (three) need additional increase
Add about 2400 yuan of labour cost, finished product reinforcing member needs additional branch relative to the average every group of batter post of conventional steel fastener lease expenses
About 600 yuan out, amount to 24 groups of batter posts, it is contemplated that save the cost (2400-600) × 24=43200 yuan.
(2) exempt to plaster when taper pile shuttering uses mirror surface formwork decorations
Batter post plastering is more complicated than the plastering of general column, and plaster about 35 Yuan/㎡ of price in this position market, this engineering batter post lateral area is total
About 2200 ㎡ exempt from 77000 yuan of estimated saving expense of plastering using mirror surface formwork decorations.
To sum up, amount to and bring about 12.02 ten thousand yuan of benefit.
In addition, the present invention has many advantages, such as suitable for actual items:
1. the present invention carries out simulator locating using softwares such as Tekla, two-dimension plane structure is converted by three-D space structure, just
It constructs on site.
2. armored concrete batter post is considered as Vierendeel girder by the present invention, formwork system calculating is carried out.
3. hole is not present without screw rod eye in template of the present invention, without part bee caused by spillage after the completion of concreting
Nest pitted skin, without cutting off the Screw arbor with nut at both-ends deformed in column, the mould bases that batter post can be improved in easy demoulding is used in turn rate.
4. the present invention is not easy the case where vibrating according to batter post concrete, optimised coagulation soil match ratio adjusts Control Measures for Concrete Slump
Degree is vibrated using the assistance of PVC chute when concrete vibrating, and the molding of batter post reinforced concrete structure is good.
5. using sizing reinforcing member the proportion of goods damageds of material are effectively reduced, in similar construction process in tie of the present invention
In may be reused, meet the requirement of green construction.
As described above, must not be explained although the present invention has been indicated and described referring to specific preferred embodiment
