Beam and crossbar formwork is a special type of construction equipment for pouring concrete surfaces. Construction companies use this type of formwork during construction:
Beam-beam formwork is used for the construction of complex and simple concrete forms. As a rule, it is necessary to use lifting equipment for installation. In the assembled form, the already mounted beam-crossbar formwork is lifted using a crane, for which the formwork is equipped with crane loops.
The main nodes of the beam-crossbar formwork are:
The beams are made of wood material, provide the shape of an I-beam, which is suitable for fastening crossbars and plywood panels. The I-beam design provides high beam strength by correctly distributing the load and pressure of the concrete mass. Beams are often equipped with metal tips, or use another material. This ensures the durability of the part and less wear during operation.
The crossbar is made of steel, which has great mechanical strength and hardness, which is required for work in difficult conditions of monolithic construction. The surface is painted to protect against corrosion, which destroys the metal and reduces the service life. Steel crossbars are fixed relative to the beams perpendicularly and perform a fixing, holding function.
The number of crossbars is calculated based on the height of the beams. From the bottom, 35-45 cm recede and then for each 1.0 - 1.4 m of beam height, one crossbar is needed.
There is a certain formula for calculating the number of beams and crossbars. For a crossbar 1.1 m long, 4 beams are required, 1.2 m long - 5 beams, 1.45 m long - 6 beams, etc.
The number of beams and girders for casting concrete columns of square section is also specially calculated.
If the height of the concrete surface is higher than the height of the existing beam, extension is applied. Steel plates make it possible to connect two beams into one. It is also possible to connect two crossbars using an insert and wedges. Therefore, a technical project of almost any complexity can be solved using beam-beam formwork.
This construction equipment is an ideal formwork for the construction of monolithic structures and walls, very often used in urban construction.
