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.

Revolving Dismantled Box Girder Formwork

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,: Calculation of foundation beam! When the cap is to be deducted beam

Q:How to do the foundation beam template: The main body of each layer of concrete using fixed pump delivery. Before pouring, it is necessary to clear the debris in the template and advance the wet mode, the concrete vibration needs to be timely, coherent, and shall not leak slurry, reinforcement intensive place need to strengthen the vibration, to ensure the concrete density. Concrete vibrator should try to avoid the direct vibration of the template, to prevent the expansion of the joints at the seams, so as to set up the site to inspect the quality of the template.Wall column concrete pouring in place, to prevent the beam, the plate when pouring overflow phenomenon affect the appearance quality, the wall column concrete pouring should be carried out in time for two times to ensure that the structure section size is correct, the founder does not distort deformation.

Q:How to support 6m arc beam template how to set up?: 6m beam if the horizontal direction of the arc beam, when the template is located at the end of the mold and the side of the mold is a patchwork way to support the mold, the arc is not small 500mm or 1000mm together, if the arc is large 300mm or 200mm together

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

Q:The calculation of formwork engineering quantity of ground beam needs to calculate the bottom of beam: Slowing down the negative effect of uneven settlement. There are difference and ring beam (beam) foundation beam mainly links, enhance the level of rigidity, sometimes used as underfill supporting beam wall, without considering the seismic effect.

Q:10-3 degrees of weather, cast in situ floor and girder formwork can be demolished a few days? 25 days enough? There's a wall on the beam.: When the bottom formwork of the reinforced concrete slab with a span of 5m is removed, the concrete strength should be greater than or equal to 75% of the standard value of concrete cube compressive strength.

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:When Liang Banzhong beam template calculation is the calculation of him in the board? Because in the calculation of engineering quantity of concrete beam by beam plate calculation. But when the template is, the book is not clear. In the calculation of the time quota template can have a beam plate.I use the Guizhou 04 quotaEspecially your last sentence, I haven't said anything yet,There is the Guizhou 04 fixed and did not say what sub beam frame beam separationAbove the beam plate is to explain the main beam, sub beam and plate, according to the calculation of beam and plate volumeThen you explain to me the frame beam is not the main beam? According to this explanation, why do you separate the frame beam: Calculate the area between the axis, into the wall of the plate into the area of the plate, and then deduct more than 0.3 of the hole, that is, the area of the beam plate

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: The template of the beam can be completed in two or once. The two is complete, first beam bottom mould, then binding steel beam and plate, and side template; a beam bottom and side is template template and template to support end, then lashing steel beam on the template, binding after the beam falls on the beam within the template, and then tie plate reinforced.

Q:For example, the 0.14 long girder thick 400x600 26 how to calculate the amount of engineering template: Calculating the area of template according to the contact surface
