What Is a Lattice Girder?

A frame beam (KL) refers to a beam connected at both ends to a frame column (KZ) , or a beam connected at both ends to a shear wall but having a span-to-height ratio of not less than 5. Now in structural design, there is another point of view on frame beams. Beams that need to participate in earthquake resistance. Pure frame structures are becoming less and less common with the rise of high-rise buildings. Frame beams in shear wall structures are mainly involved in earthquake resistance. Beam. The construction elevation of the frame beam and the cast-in-place slab are generally the same in the architectural drawing, and the structural elevation is generally a few centimeters lower than the building elevation (usually 5 cm), but the structural top elevation of the frame beam and the cast-in-place slab are generally the same. Similarly, in special cases, such as when the kitchen and bathroom need to be lowered, it is flush with the top of the floor. There are two relations between the slab and the frame beam: one is: the slab is cast in place, then it must be constructed at the same time, the steel bars are tied, the formwork is supported, and the concrete is poured, so that the structural elevation of the slab and beam is the same (unless the bathroom, kitchen, etc. The part that needs waterproofing to find the slope, because the construction of the main structure needs to be waterproof and other architectural practices. In order to ensure that the plate height of this part can be coordinated with other rooms after these practices are completed, it is necessary to lower the height in advance, which is generally 5cm. If other drainage methods such as floor drains are required, they need to be lowered by about 35cm, and the slag concrete is used for backfilling after the completion of the hydropower construction. The second is: the board is a prefabricated board. After the beam is laid, the prefabricated board is placed, so that the elevation of the beam is generally one board lower than the elevation of the board, and the same, it requires the beam to be shaped, that is, the blue beam. Frame beams can be divided into: roof frame beams, floor frame beams, and underground frame beams. Among them: the underground frame beam refers to the beam code (DKL), which is set above the top surface of the foundation and below the building elevation plus or minus zero (indoor ground) and uses the frame column as a support.

The frame beam is also called a frame beam. It has an anchor frame beam and an anchor cable frame beam. The frame lattice is composed of beams and vertical beams in a grid shape. The construction can be precast or cast in place.
