Description

  The present invention relates to a joint structure between a roof panel formed by providing a roof frame material such as a deck plate, a heat insulating material, and a waterproof sheet on a steel frame material and a steel roof beam.

Conventionally, when a roof panel made of a deck plate or the like is supported on a steel roof beam, the roof panel is joined to the roof beam with a bolt so as to be separated and disassembled. The roof panel is a steel frame material on which a roof frame material, a heat insulating material, and a waterproof sheet are integrally provided, and is manufactured in a factory.
Conventionally, in the bolting of the roof panel to the roof beam, a receiving material 50 which is a receiving portion 50a made of channel steel having an upper portion opened upward as shown in FIG. 23A is raised above the roof beam 51. And fixed. A steel frame material 53 of a roof panel is stacked on the receiving portion 50a of the receiving material 50, and the frame material 53 and the receiving portion 50a of the receiving material 50 are bolted. The receiving portion 50a of the receiving member 50 is provided with a bolt insertion hole and a sino hole. In this case, since the receiving part 50a of the receiving material 50 is made of channel steel, the frame material 53 is roughly positioned and prevented from being displaced at the same time by overlapping the steel frame material 53 of the roof panel on the receiving part 50a. . The bolts are tightened using the lower space of the raised receiving material 50.

However, in the above-described joint structure between the roof panel and the roof beam, the bolt joint portion is located immediately above the roof beam 51 as shown in FIG. 50 lower space had to be used, and the electric tool could not be used for bolting, which was very laborious.
Also, when lifting the roof panel, the suspension bolts could not be used, and they were lifted by wire slings, which took time and effort. When lifting with a sling, the roof panel becomes slippery and there is a risk that the wire may come off, which makes the workability poor and dangerous.
Furthermore, since there is a bolt joint portion directly above the roof beam 51, Shino cannot be used, and the bolt insertion hole provided in the frame material 53 of the roof panel and the receiving portion 50 a of the receiving material 50 are provided. It was difficult to align the bolt insertion holes.

The objective of this invention is providing the junction part structure of the roof panel and roof beam which can perform the bolting of the roof panel on a roof beam with sufficient workability | operativity.
Another object of the present invention is to provide a joint structure between a roof panel and a roof beam that allows a roof panel to be lifted on site in a safe manner with good workability.

The joint structure of the roof panel and the roof beam according to the present invention comprises a roof panel supported on a steel roof beam, and the roof panel is formed of a roof frame on a plurality of parallel steel frame members. In the roof structure in which a heat insulating material and a waterproof sheet are provided, the roof panel and the roof beam are joined to each other, and in at least a part of the roof panel, the frame material of the roof panel is positioned on the roof beam. And, on the upper surface of the roof beam and the lower surface of the frame material, a beam-side alloy and a panel-side coupling piece projecting laterally and overlapping each other are provided, and bolts inserted between these alloy alloys that overlap each other Thus, the roof panel and the roof beam are joined together.
According to this configuration, the panel side connecting piece protrudes to the side of the roof panel frame material, and the beam side alloy also protrudes to the side of the roof beam. The joining can be easily performed using a power tool from the lower side of the roof panel frame material and the roof beam. Thereby, the bolting of the roof panel on the roof beam can be performed with good workability.

In this invention, you may provide the slip prevention material which protrudes upwards and prevents the position shift of the said frame material of the said roof panel in the said beam side alloy material.
In this way, by providing the beam side alloy material with the displacement preventing material that prevents the displacement of the roof panel frame material, it is possible to prevent the risk of the roof panel falling off during or after the installation of the roof panel.

  In this invention, the roof covering material is a deck plate, and the arrangement direction of the wavy mountain is a direction perpendicular to the frame material, the frame material protrudes from the edge of the deck plate, and the protruding portion of the frame material, A suspension hole for engaging the hook of the suspension rope may be provided. Thus, by providing the suspension hole in the projecting portion of the roof panel frame material from the roof frame material, the hook of the suspension rope can be engaged with the suspension hole, and the roof panel can be lifted on the roof beam. For this reason, the roof panel is lifted in the field because it does not take much time and the roof panel does not slip and become unstable as in the case of lifting the roof panel with a wire sling as in the past. Can be performed safely with good workability.

  The joint structure of the roof panel and the roof beam according to the present invention comprises a roof panel supported on a steel roof beam, and the roof panel is formed of a roof frame on a plurality of parallel steel frame members. In the roof structure in which a heat insulating material and a waterproof sheet are provided, the roof panel and the roof beam are joined to each other, and in at least a part of the roof panel, the frame material of the roof panel is positioned on the roof beam. And, on the upper surface of the roof beam and the lower surface of the frame material, a beam-side alloy and a panel-side coupling piece projecting laterally and overlapping each other are provided, and bolts inserted between these alloy alloys that overlap each other Thus, since the roof panel and the roof beam are joined, the bolt joining of the roof panel onto the roof beam can be performed with good workability.

The joint structure between the roof panel and the roof beam is a joint structure when the roof panel 2 is supported on the steel roof beam 1. The roof panel 2 is provided with a roof covering material 4, a heat insulating material 5, and a waterproof sheet 6 on a plurality of parallel steel frame members 3. Since the roof panel 2 can be manufactured at the factory, the on-site construction period can be shortened, and it is possible to improve the safety by reducing the work at high places on the site. The roof beam 1 is a beam that is a roof beam or the like, and is made of, for example, a square steel pipe. The frame material 3 of the roof panel 2 is made of channel steel, and the roof covering 4 is made of a deck plate, but may be a keystone plate. The heat insulating material 5 is made of, for example, an extruded polystyrene foam.

Is provided. Bolt insertion holes 9 and 10 are respectively provided in the beam-side alloy 7 and the panel-side coupling piece 8 that are overlapped with each other, and bolts 11 (FIG. 3) inserted through the bolt insertion holes 9 and 10. The roof beam 1 and the roof panel 2 are joined. In the example of FIG. 1, among the three frame members 3 of the roof panel 2, the panel-side coupling piece 8 is provided on the center frame member 3 and the right frame member 3 in the drawing. The panel-side coupling pieces 8 provided on the central frame member 3 protrude on both sides of the frame member 3, and the panel-side coupling pieces 8 provided on the right frame member 3 protrude only on one side which becomes the panel central side.
