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.

Q: Is there a beam plate template that is used to calculate the engineering quantity of the beam formwork or the engineering quantity of the beam and the plate? Urgent thank you: There is a beam slab template engineering quantity = beam template + plate template; beam template and plate template are calculated according to the beam plate

Q: What is the foundation beam template: The foundation beam without the beam side template of this code, the foundation beam is not calculated at the bottom of the template, select the basis of the beam on the beam directly to the template area.

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,: The calculation of the net area on both sides of the formwork. Cushion volume should be very good

Q: Which part of the middle beam and side beam in the T beam template? Thank you: So there are [side span beam], [cross the middle beam], [medium span beam], [across the edge beam] four kinds of distinction. The amount of concrete, steel is a little different

Q: The formwork support is a beam template which is connected with both sides of the vertical rod and the force at the bottom of the beam and the force of the vertical wire rod which is arranged below the transverse beam at the bottom of the beam: Note: when the right angle fastener tightening torque of 40--65N.m, test shows that the single fastener will slide in the 12kN under the load, the sliding bearing capacity of desirable 8.0kN; double fastener will slide in the 20kN under the load, the sliding bearing capacity to be 12.0kN.Note: the above values are experimental values! Take a look at your calculation results and this value to meet the double anti sliding bearing capacity can be!

Q: How to support 6m arc beam template how to set up?: After setting out in accordance with graphics support ah. If the curvature is large, it can be approximated by linear segmentation.

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: Generally, there are two kinds of formwork support:Area of contact surface between concrete and formwork

Q: The calculation formula of the beam column for the construction of the concrete and the use of the template area of the detailed point of the best thank you: Refer to JGJ 162-2008 construction formwork safety technical specifications

Q: I would like to ask the template support system Liang Xiaoliang Ban Xiaoliang refers to what: Plate is a template, bamboo plywood, wood plywood. The small beam is directly supporting formwork wood architrave, there are several kinds of pine, the section size of 30 x 80, 40 x 80, 50 x 100. Support is wood brace steel bar, also called beam
