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: 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: 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????: 1, in order to prevent the concrete weight and construction load to other beam and plate template pendulous; if there is no design provisions, the arch height is the length of the cross beam and plate 1/1000~3/1000; (general wood template for 1.5/1000~3/1000; steel template for 1.5/1000~2/1000.)

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: The bottom of the board 12.24*7.44 why not *2 floor 12.24 of the two of the 7.44 also have the plate side mode *2 is * of the two or both: The beam of the template is to calculate the beam height (minus the plate thickness of the part) * net long *2 surface. The bottom die has been calculated in the bottom plate.Louzhu certainly not familiar with the construction site, as long as the scene to see how the template is placed.

Q: There are times when the beam is not to deduct the secondary beam on the main part of the beam?: The bottom of the beam is provided with two side edges, and the side edges are counted to the bottom of the plate

Q: The formula for the calculation of beam, concrete and brick: According to the section size of the picture multiplied by the length of the beam. The length of the beam and the height of the beam shall be determined according to the following provisions:1, when the beam is connected, the length of the beam to the column side.2, the main beam and secondary beam connection, the second beam length to the side of the main beam. The volume of the beam head and beam in the wall is calculated into the beam volume.3, and lintel connection, respectively apply lintel beam, fixed. Lintel length calculation according to the requirements of the design, design requirements, width according to windows and doors, both ends of the 250mm calculation.4, ring beam and beam connection, beam volume should be deducted into volume within the beam.In 5, beam parts picked out wall concrete beams with external edges out of bounds, according to the size in cubic calculation, apply a single beam and continuous beam project.

Q: Beam column plate template how to calculate the need to deduct what part?: The second is to calculate the template of the beam to calculate the template of the beam with the section length multiplied by the length of the unit is M2Finally the board notice when calculate the template template amount is peripheral template must take and post together part to deduct the intersection with beam part to be deducted

Q: A set of 50 m T beam steel template weight: Fifty m T beam steel formwork, a complete set of general must contain a set of side beams in the beam half

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: What are the main composition of the beam template: D> suspended beam formwork support composite structure A> roof formwork support composite structure consists of main beam (main dragon's back), auxiliary beam (vice dragon), support rod, cross bar composed of B> shear wall formwork supporting structure.
