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: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:Calculation of beam and column formwork
Tell you a definition, you will understand
Q:Calculation of the area of beam formwork
Beam: beam length multiplied by the end of the beam and 2 times the length of both sides, the beam length to the side of the column, the wall side, the second beam to the main beam side, the outer part of the calculation of the center line, according to the calculation of the internal part of the net long linePlate: the column, beam, 0.3 square meters outside the hole area
Q:Calculate the beam template when you want to reduce the thickness of the plate
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.
Q:How to determine the height of cast in place concrete beam formwork
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:Cast in situ floor and girder formwork can be removed a few days?
If it is summer side touch about 5-7 days is not a problem, the floor of the bottom mold principle that needs to be kept until the floor block to achieve strong design. After the test block strength test qualified to dismantle the bottom mold testing stations in concrete, but in the bottom die and the support under the premise of more than 7 days can be started in the above line ready on a layer of formwork, about 10 days can start pouring a layer of concrete.
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:What is a large volume template? How much is the cross section of the beam, belonging to the large volume template?
According to the "dangerous method" sub project safety management of the construction quality of [2009]87, the height of more than 5m, the total construction loads greater than 10kN/m2, or the template support system concentrated line load greater than 15kN/m to prepare special construction scheme
Q:How to control the elevation of the beam bottom and the axis position
Above the control points on the scaffold steel pipe before supporting formwork
Q:Remove the larger span of the beam pillar template why should be removed from the middle to the two ends
The maximum bending moment in the middle of the beam is removed from the middle of the support, the stress is concentrated on the two supporting end, and the final force form is the same as the reinforcement of the beam, and the bending and the excessive shear force are not generated
