Product Description:

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.

■  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: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:When the height of the beam is large, the reinforcement of the beam is bound on the bottom of the beam
The wooden wall on both sides of a beam hour after tie beam.A large beam of a closed wall or two edges are not tied on the tie Liang
Q:I would like to ask the three sides of the template is calculated on the surface of which is the three?
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:According to the experience, who knows the construction area and template, plate, column, beam volume, steel, etc.!
Multi storey residential building structure of each floor area of square meters of content: the template to expand the area of about 2.4 to 2.9 square meters, concrete about 0.42 LiAbout 55 meters, reinforced to 65Kg.Basement floor area per square metre of content: the template to expand the area of about 2.4 to 3 square meters, concrete about 0.8 to 1.1 cubic meters,Steel bar about 125 to 170Kg.
Q:What kind of frame beam formwork
Application of cast in situ concrete formwork beam single beam, continuous beam combination of steel formwork support! But don't forget, scaffolding, templates, and membranes. Specific look at your project and your province of the quota
Q:When the main beam is connected with the secondary beam, the area of the template is calculated
It would take the high beam length reduced thickness, and by 2, the last plus beam bottom
Q:Calculate the engineering quantity of the beam template or the engineering quantity of the beam and plate
As long as the board and the board together (usually for the plate in the beam), together with the count; not together with the other
Q:How to calculate the beam model
Calculating the area of template according to the contact surface
Q:How to calculate the length of the beam, beam template area
Is the template area, there are two times in each cross beam, then the results of the calculation of the sub beam cross-sectional area (a few minus a few) is the
Q:How to determine the height of cast in place concrete beam formwork
Span multiplied by 1/1000~3/1000, can not be so precise, the general is probably about two or three cm
