These forms take up less space after deformation, which is very important in the regularity of the workshop environment and their movement. The “expandable column forms” resistor is designed and manufactured for fresh concrete with a pressure of 80 kg / m ^ 2 The cross-sectional dimensions of the column are increased from 20 × 20 cm to 60 × 60 cm in 5 cm increments and form square or rectangular sections. These forms can be moved seamlessly by crane. – Using formwork oil to increase the quality of the concrete surface and the durability of the forms Expandable forms: – Proper concrete sealing to prevent the concrete syrup from slipping and creaming – Observing the cover of reinforcements in the concrete column – Determining the quality of formwork and materials according to whether the column is facade or non-facade
It is not allowed to give forms or scaffolding to adjacent columns. Remove the wood chips and excess material and block the hole during concreting.įixing the position of the column should be done only by wooden beams that are placed in four directions at the foot of the column on the floor and pouring concrete to the dimensions of the column to stabilize its position is not allowed in any way. The minimum thickness of the board to be used for forms of columns is 3 cm.Ī hole with dimensions of 10 10 10 should be installed at the foot of each column. It should be noted that when installing the concrete forms, the columns must be installed completely vertical because if the column is complete If it is not vertical, the incoming loads are not axial and uncalculated moments are created in it and cause the destruction of the building. The concrete column forms must be opened after 48 hours because otherwise watering the concrete is not easy and the concrete may dry out and burn.
Concrete forms to go around columns install#
To prevent this, it is better to install triangular wicks in the corners of the forms to create slopes inside the forms so that the concrete poured into the concrete forms is not sharp-edged. When opening the concrete forms, it should be noted that Carefully separate the concrete forms so that the sharp corners of the column are not damaged. In the case of concrete column forms, the forms are usually opened as soon as the concrete loses its mental state and can retain its geometric shape, and this is about 48 hours after concreting. These braces should be connected by rebars and nuts or carpentry wire. The maximum distance between these braces should not exceed 80 cm. It should be noted that the backrests of the opposite sides, firstly, are about 10 to 15 cm more than the width of the concrete forms, and secondly, the backrests of the opposite sides should be placed directly opposite each other so that when connecting the four sides of the column to each other by connecting carpentry wire to this The appendages can be easily connected to each other. It should be more than mentioned in the map to give us the desired dimensions from inside. Considering that in the form of columns, the two opposite sides are placed inside the other two sides, as a result, the width of the other two sides of the concrete forms should be equal to the thickness of the board. Sometimes the architect of the building may suggest other sections in terms of aesthetics such as circle, oval, etc., and to form the columns, first determine the dimensions of the column from the map and the two sides of the forms in the same amount of boards.Ĭut the appropriate ones and nail them to the four-cut woods up to that backing. Most of the concrete column forms are quadrangular. If thought needs concrete column forms or more information about concrete column forms, contact us now. We produce our products according to international standards and using the best Middle Eastern experts, we offer you products with the best quality and price. Modern Ghaleb is the best manufacturer of concrete formwork and scaffolding equipment in the Middle East. It is better to use plumb jacks to run the columns more accurately.
To prevent the columns from twisting, it is recommended that the corners and the concrete steel formwork used in the concrete column forms are not of the same height.įor example, if you use 150 cm angles, the size of the concrete steel formwork panels should be 100 and 200 cm. Medium clamp pipe clamps are attached to the body of the concrete formwork.įor columns larger than 60 × 60 cm, studs with long clamps are used.
There are two types of restraints: tubular restraints and gutter restraints that are made exactly in the form of a goniometer. Using concrete column forms and outer corners of concrete form, all kinds of the square, rectangular and polygonal columns can be formatted.Ĭonstraints are used to hold the column surfaces relative to each other.
