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.

Box Girder Steel Formwork

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 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: What is the wire mesh in front of the foundation beam: Beams are reinforced, how to put into the template? How can we ensure that the concrete does not flow out? Wire netting is the best way

Q: How to calculate the amount of beam template? FiveKL2: cross section size of 0.3*0.6, thickness of the 0.12 beams, 10.9 JingchangAsk: how to calculate the amount of formwork works? How to calculate the height of support?Calculation formula: If it is in the middle, the template area = (0.6-0.12) *2+0.3] squareThe height of support is calculated according to the height of beam bottom

Q: According to the experience, who knows the construction area and template, plate, column, beam volume, steel, etc.!: Non residential frame structure of each floor area of the content of the square (excluding basement): template development area of about 2.2 to 2.6 square meters,About 0.35 cubic meters of concrete, steel bar about 50 to 60Kg.

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: 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 general situation is calculated according to the contact area between the concrete and the template

Q: The section size of the beam is 200 x 400 the size of the board is 4500 x 4000 plate thickness of the formula for 120 - a rookie: Building template:Building template is a temporary support structure is made according to the design requirements, the concrete structure components, according to the position and size of the provisions of forming, maintaining its correct position, external loads and under construction template gravity and acting on the. The purpose of template engineering is to ensure the quality of concrete engineering and construction safety, speed up the construction progress and reduce the cost of the project.This paper introduces the construction formwork structure of cast-in-place concrete structure construction, which is mainly composed of three parts: the panel, the supporting structure and the connecting parts. The panel is in direct contact with the bearing plates of concrete; supporting structure is a temporary structure supporting panel, concrete and construction load, ensure the construction template are firmly combined, do not deform and damage; the connecting piece is connected to the panel and the supporting parts of the whole structure.Building formwork is the concrete pouring forming shell and support, according to the nature of the material can be divided into building template, building wood plywood, covered with plastic board, multilayer board, double-sided adhesive, double-sided coated building template. According to the construction process, the construction formwork can be divided into the cast in place concrete formwork, the pre assembled template, the large formwork, the jump formwork and so on.

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: First of all, what are the construction of the structure of the template, such as walls, columns, beams and ladders, which is the structure of the first installation of the template after the installation of steel? Ten: Who told you that?. Shear wall, column is the first binding steel, and then close the template, if the two sides of the shear wall formwork and the death of the death of the column template, but also how to bind and connect steel
