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: The calculation of formwork engineering quantity of ground beam needs to calculate the bottom of beam
- The calculation of the formwork quantity of the beam is not needed to calculate the bottom of the beam
- Q: Why is Changshi beam, but also computing to the side or side column beam?How to deduct the overlap area between beam and plate, column and wall, wall and wall
- The connection between the column and the beam and the place where the beam is connected with the beam does not need to be deducted from the area.
- Q: How to do irrigation formwork
- For your understanding of the 200*350, this is the inside of the beam height. The true beam is 200*500. without the need to deduct plate thickness
- Q: For example, a beam 200*400, length 5000Plate thickness 1005000*5000The area of the template is1, (0.2+0.3*2) *5+5*52, 0.3*2*5+5*5Which is right
- Plate side mode *2 is the circumference of the board (minus column protruding part) multiplied by the thickness of the plate 0.1M
- Q: Beam column plate template how to calculate the need to deduct what part?
- Plate under the formwork and then if there is a beam under the board, then the beam and the plate side of the area to cut off the sideDo not understand the words can continue to ask
- Q: How to do the foundation beam template
- Construction sequence: the structure of the column to tie the tendons to the skin of the number of poles to wall masonry before the first floor on the ground has been played by the large axis of the wall body axis and the line. The surface of the base should be clean and wet. When you start the masonry, the brick should be placed and the seam width should be discharged. In the walls before the first vertical skin pole pole, skin should be marked with each skin brick and mortar joint thickness, lintel ring, position, number of rod should be set up in the skin of the building end corner, wall aspect junction and interior wall. Masonry should be up and down the wrong seam, inside and outside the lap, gray seam straight full, the level of gray seam thickness and vertical ash seam width should be controlled at around 1-1.1cm
- 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: When there is a beam plate template, the beam can not be added to the template?
- Beam template and foundation beam template to separate sets of fixed!
- Q: How to calculate the intersection of rectangular column and beam
- Column high: beam slab column column should be high since the surface (or floor surface) first height calculation between the surface layer of the floor slab; column height should be from column surface (or floor surface) to calculate the height of column cap between the lower surface of the frame column should be high; the height calculated from the upper surface to the top of the column base; structural column height should be at the bottom of the column to column (from beam bottom) height calculation;
- Q: How to control the elevation of the beam bottom and the axis position
- Above the control points on the scaffold steel pipe before supporting formwork
