Embodiment Construction

[0010] Including upper channel steel 1, upper c-shaped steel 2, lower c-shaped steel 3 and lower channel steel 4 stacked from top to bottom, in which two c-shaped steel webs are back-attached and connected, and the webs of the upper channel steel and the lower channel steel are respectively It is connected with adjacent c-shaped steel coils, and the outer surface of the web of the upper channel steel and the lower channel steel is welded with a strip-shaped connecting ear 5 with an L-shaped cross-section. The connecting ears are two and correspond to two coiled edges on a c-shaped steel , the connecting ear is surrounded by the webs of the upper channel steel and the lower channel steel to form a connecting slot for fastening the c-shaped steel coil ear, and the c-shaped steel coil ear can be inserted and fixed in the connecting slot, and the c-shaped steel and the groove The steel web encloses a groove-shaped channel, and at the same time, in order to further strengthen the st...

Abstract

The invention discloses a grooved beam aiming to solve the problem that in the prior art pipeline-like infrastructures take many spaces. The patent scheme is as follows: the grooved beam is characterized by comprising an upper groove steel, an upper C-type steel, a lower C-type steel and a lower groove steel which are in overlap arrangement from top to bottom, two C-type steel abdomen plates are connected back to back, abdomen plates of the upper groove steel and the lower groove steel are respectively in turned edge connection, and a groove type channel is formed by encircling of the abdomen plates of the C-type steels and the groove steels. The groove type channel is easy to accommodate various necessary floor-among infrastructures such as multi-storey building connecting lines, channels, pipes and the like. The infrastructure grooved beam not only can accommodate the groove type channel, and on the other hand, also is designed into a relatively-simple and easy-to-frame organization structure to provide a necessary and usually-processed beam bearing function.

Description

technical field [0001] The invention relates to a beam on a building. Background technique [0002] Frame beams are beams that are connected at both ends to building frame columns. Frame beams can be divided into: roof frame beams, roof frame beams refer to the frame beams at the highest part of the frame structure roof; floor frame beams, floor frame beams refer to frame beams on each floor; underground frame beams, underground frame beams refer to It is set above the top surface of the foundation and below the positive and negative zero of the building elevation and is supported by frame columns, and is not affected by the reaction force of the foundation, or the reaction force of the foundation is only produced by the self-weight of the underground beam and its covering soil, not by the upper load The effect of such underground beams is called underground frame beams. [0003] At present, the existing frame beams are generally only used in the building frame to support ...
