BOX GIRDER
External formwork of 32/24 meters post-tensioning concrete pre-faricated box girder is divided into sliding mode and
rolling mode; the side form of the first mode can move from one bottom form to the other one which increases the
utilization rate, and decrease the investment for the formwork during construction; the side form of the second mode
is relatively fixed according to the bottom form, and could be dismantled by revolving, which improve the efficiency
of formwork closure.The side formwork unit is mainly 6 meters, the design of the sructure is compact
and reasonable with beautiful and smooth appearance.
Features
■ All the edges of ecternal formwork panels for the box girder have been milled, which ensure
the assembly precision to avoid the leakage of the concrete
■ The bottom formwork unit is 3 meters to facilitate the installation and anti-arch adjustment
■ The bulkhead is designed to envelop the sideform,which can be wholely assembled, making the removal, installation and adjustment much easier.
- Q:I would like to ask the template support system Liang Xiaoliang Ban Xiaoliang refers to what
- High formwork concrete beams are usually large in size, gravity load, plan people sometimes use 50 x 100 (width * height) wood brace, called Liang Xiaoliang, a thin concrete slab gravity load is less, with 30 * 80 mu Fang, challenge the small beam. According to the different rib beam floor plan, good people, they try to use the same specifications of the wooden architrave, there is no Liang Xiaoliang, small plate beam, just calculate book Liang Xiaoliang, trabecular plate.
- Q:More than the number of square cross-section of the beam high formwork
- According to the "dangerous method" sub project safety management of the construction quality of [2009]87, the height of more than 5m, the total construction loads greater than 10kN/m2, or the template support system concentrated line load greater than 15kN/m to prepare special construction scheme
- Q:Seeking beam, plate template engineering quantity
- Plate template (bottom area): (2.6*3- wall thickness) * (2.4*3- wall thickness) - (2.4*3- wall thickness) *0.2*2 [main beam] - (2.6*3- wall thickness) *0.25*2 [sub beam]
- Q:Remove the larger span of the beam pillar template why should be removed from the middle to the two ends
- Remove from the ends of beams began to load, is Liang Hezhu nodes under pure shear, a shear deformation from the middle split beam gradually remove support, after the load is gradually increased, the shear in the support under the protection of gradually increasing load, small impact.
- Q:What is the formula of beam slab formwork
- Si=F*A*B, formula, F coefficient, A, length, B width or height.Such as triangle F=0.5, A for the bottom edge of the length, B is high.
- Q:How to do irrigation formwork
- Pro, beam section is marked on the drawings, the beam is 200*500.
- Q:What is the demolition order of the construction template
- Template removal sequence:General is the first non load bearing template, but bearing template; the first side plate, the back plate. Follow the line after the demolition, the demolition of non weight-bearing parts, the demolition of the load-bearing parts and the principle of top-down,
- Q:What is a large volume template? How much is the cross section of the beam, belonging to the large volume template?
- The above construction total load of more than 10kN/m2, or concentrated line load greater than 15kN/m template support system that belongs to the template, if you do not consider other loads, considering the single weight, according to concrete 25000KG/m3 calculation, then the beam section area of 0.4m2 belongs to the template, such as 400*1000, 300*1350, 500*800 etc.. Central line loads can be calculated in similar ways.
- Q:When the height of the beam is small, the beam of the beam is tied up on the top of the beam formwork; when the beam height is large, the steel bar of the beam is bound on the bottom of the beam. What do you mean?
- When the beam height is large, the beam of the steel beam in the bottom of the bundle, which means that the beam of the overall weight of steel, in the Liang Dimo binding, and then seal the side template, and then pouring concrete
- Q:The section size of the beam is 200 x 400 the size of the board is 4500 x 4000 plate thickness of the formula for 120 - a rookie
- A beam plate:1, according to the sum of the contact area of the template template.2. The area of the beam should be deducted.3, the beam of the template is to calculate the beam height (minus the thickness of the plate part) * net long *2 surface. The bottom die has been calculated in the bottom plate4, the bottom plate is the bottom plate of the whole plate (including the bottom of the beam), and then subtract the column area. The board only needs to calculate the bottom mold and the side die.
