A roof structure includes: horizontal base materials forming a roof slope; and roof panels fixed on the horizontal base materials and spread side by side in a slope direction, each of the roof panels includes a roofing board, and rafters fixed to a lower surface of the roofing board in parallel to each other, and extending perpendicularly to the horizontal base materials, each of the rafters of one of the two adjacent roof panels in the slope direction includes a carry-out portion projecting from an edge of the roofing board, each of the carry-out portions being between the rafters of the other roof panel and fixed to the roofing board of the other roof panel, a projection length of the carry-out portions is smaller than a distance between the adjoining horizontal base materials, and the carry-out portions and the other roof panel are fixed to the same horizontal base material.

Roof panel, roof structure, and roof structure construction method

A representative roof frame structure incorporates: paired wood sloping beams respectively extending from a ridge portion toward eaves on opposite sides from each other; a hanging portion hanging vertically downward from the ridge portion; and two steel braces respectively installed between lower faces of the sloping beams and side faces of a lower end of the hanging portion, wherein one end of each of the steel braces is pin-jointed to a beam-side fixing portion protruding from the lower face of the sloping beam, and the other end of each of the steel braces is pin-jointed to a hanging-portion-side fixing portion protruding from the side face of the lower end of the hanging portion.

Roof frame structure

A pipe connecting device having a joint body including a fitting cylinder to which a flared synthetic resin-made tube is to be externally fitted, an external thread formed on a radially outward side of the fitting cylinder; and a union nut including an internal thread screwed with the external thread, and a tube pressing portion that presses a diameter changing portion formed between a flared portion in the tube, and a non-flared portion, in the direction of the axis. In a fastening completion state in which the tube pressing portion is caused to press the diameter changing portion by a screw advancement of the union nut, the screw advancement being produced by screwing the internal thread to the external thread, positions of a basal end of the external thread and a tip end of the union nut in the directions of axes coincident with each other.

Pipe connecting device with fastening completion structure

A resin pipe joint including: a synthetic resin-made joint body including an inner cylinder portion, an external thread portion, and a radial groove m into which an end of a tube enters; and a union nut that is made of a transparentable fluorine resin, and the union nut including an internal thread portion, a seal peripheral edge which presses a tip end portion of a tube flared portion, a slipping-off prevention peripheral edge which is actable on a large-diameter portion of a flaring changing region, and a pressing inner peripheral portion which is externally fittable to a flared straight portion.

Resinous tube joint

In a resin pipe joint having a configuration where, by a screw advancement of a union nut caused by screwing an internal thread to an external thread in a state where a tube is externally fitted to an inner cylinder to form a flared portion, a flaring changing region is pressed by a seal pressing portion, a torque varying portion in which projecting portions of a joint body and recess portions of the union nut are fitted to or unfitted from each other by a flexural displacements of the projecting portions in the direction of the axis in accordance with fastening rotation of the union nut from the vicinity of a portion in front of an end of the screw advancement, the screw advancement being caused by pressing of the seal pressing portion against the flaring changing region is configured.
