Problems solved by technology

At the support end portion 82 of this one plate, the force supporting the ceiling support portion 78 has a limit. If the above-mentioned static load and repeated load act for a long time, the force supporting the ceiling support portion 78 will gradually decrease, and the durability strength will also show accordingly. a clear downward trend

[0055] Such as Figure 1 to Figure 3 As shown, the elongated member 1 for suspending the ceiling of the first embodiment is integrally formed by combining the suspending rod 2 with an inverted T-shaped section and the locking beam 3 with a U-shaped section.

[0056] The above-mentioned suspension rod 2 is formed of a long substantially rectangular steel plate, and its cross-sectional shape is mirror-symmetrical with respect to the center line. The suspension bar 2 is processed into an inverted T-shaped cross section by stamping a steel plate, and is composed of a locking raised portion 12 , a vertical side portion 11 , and horizontal engaging portions 13 , 13 . Here, the vertical side portion 11 is formed by stacking steel plates so that both sides of the longitudinal center line are partially back-to-back, and formed into two plates in the vertical direction. The locking protrusions 12 respectively extend from the upper ends of the two plates constituting the vertical side p...

[0092] Such as Figure 13 to Figure 15 As shown, the elongated member 101 for suspending the ceiling of the second embodiment is integrally formed by combining a suspending rod 102 with an inverted T-shaped section and a locking beam 103 with a substantially U-shaped section. The suspension rod 102 is the same as the above-mentioned first embodiment, and is formed by bending a substantially rectangular steel plate through roll forming, and consists of a locking raised portion 12, a vertical side portion 11, and a horizontal engaging portion 113. , 113 constitute.

[0093] Here, the horizontal engaging portions 113, 113 are bent and formed with ribs protruding upward (on the side of the locking raised portion 12) along the longitudinal direction at a position having a predetermined interval in the horizontal direction from the lower end of the vertical side portion 11. Section 115, 115. The rib 115 of the horizontal engaging portion 113 is bent into a mountain-shaped cross-se...

Abstract

The invention provides a long size element for suspending ceiling with high strength and endurance strength capable of supporting the ceiling long and steadily. The clamping determinate beam (3), whose section is approximately cross-sectional type, has supporting lower side part (21) attached under horizontal engagement part (13, 13) of the steeve (2) with a inverted T-type section, and supporting double-deck side parts (22, 22) retracing from two outer ends of the supporting lower side part (21) and extending inward in the way of covering the horizontal engagement part (13, 13) and retracingto extend outward and cascading. The clamping determinate beam (3) and the steeve (2) are integrated by using supporting lower side part (21) and supporting double-deck side parts (22, 22) on either side to hold the horizontal engagement part (13, 13), thereby developing high strength and endurance strength of static load and repeating load generated by enduring self weight of the ceiling (P), being capable of supporting the ceiling (P) long, steadily and properly.

Description

technical field [0001] The present invention relates to an elongated member for suspending a ceiling assembled in a lattice shape and used for suspending a ceiling. Background technique [0002] Such as Figure 17 and Figure 18 As shown, the elongated member f for suspending the ceiling is formed as follows, that is, a vertical side t is formed in a substantially vertical direction, and a cross section for fixing a hook j is formed at the upper end of the vertical side t in a rectangular ring shape. The locking raised portion i forms a locking edge portion g with a U-shaped cross-section and a lower opening at the lower end of the vertical side portion t. The elongated member f for suspending the ceiling is assembled in a lattice shape, and supports the side end portions of the ceiling p on both upper surfaces of the above-mentioned locking edge portion g. And the indoor ceiling is comprised by supporting the some ceiling p in a row. In addition, generally, the elongate ...
