BOX GIRDER

Brief Introduction

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.

Wholely Assembled Box Girder Template Made in China

Q: How to calculate the length of the beam, beam template area: The two cross KL76, distance of each cross axis of the pillar width is Jingchang (beam by beam, high *2+ Liang Kuan)

Q: Known length of 50.8 meters, known to be designed for the width of the area of the loss of 1 x 0.25, I have calculated the base cap,. {1.0 * 0.25 + [0.37 + 1 x 0.1 / 2 + 0.47 * 0.1] on the bottom and bottom formula is multiplied by the divided by two. So how to calculate the foundation beam. Formwork and cushion,: . Calculate the volume of the cushion should be very good, where the beam on the cushion ah, as to how the layout drawings will be.

Q: I only see the span is greater than 4M of the beam arch height is 1/1000~3/1000, if that is 5m, 8m, 12M, 16m and even assuming 20m, the supply is only 1/1000~3/1000????: 4.4.6 on the span of not less than 4m of the beam, the plate, the height of the template arch should be the beam, plate span 1/1000~3/1000.

Q: How to do irrigation formwork: For plate 120 H-0.05, the -0.05 here is the elevation of the plate is reduced by 5cm. - drop, + raise. Here the drop and elevation are relative floor elevation.

Q: Calculate the beam template when you want to reduce the thickness of the plate: Now the general calculation of the template area is to contact the concrete surface is positive, of course, the thickness of the template to be deducted.

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: I would like to ask the three sides of the template is calculated on the surface of which is the three? Novice do not understand thank you: The utility model relates to a three surface template beam (both sides of the beam and the bottom surface of the beam), and the other is a two side formwork beam (two sides of the beam)

Q: How to control the elevation of the beam bottom and the axis position: The axis is controlled by hanging the ball down to the lower floor axis and the axis control line.

Q: What is the formula of beam slab formwork: Rectangle, F=1, A is the length of the bottom edge, B is high.....So, S1S2, S3,..., one by one.The sum of the above Si is the total area. The amount of template engineering is required.

Q: The main floor beam template installation should pay attention to what?: 2) install the side formwork of the beam and drill the side of the side of the side of the pull screw hole after the additional diagonal reinforcement.3 check the beam center line, elevation, section size, adjacent beam column template connection is fixed.4) after the beam and plate steel reinforcement is finished, the 1/2 pairs of the beam height are put on the pull screw, and the outer part of the pull screw is coated with a hard PVC casing, and the screw spacing is 1000mm.
