Machining and manufacturing method for thermal insulation type steel frame roof panels

Abstract

The invention discloses a machining and manufacturing method for thermal insulation type steel frame roof panels. Steps are formed on the surfaces of angle steel and a frame. The steps on the two adjacent roof panels form a groove, and the width of the groove is larger than that of the gap between sheet material bodies. The groove is used for performing caulking on the gap between the roof panels, hot-rolled light steel channels are adopted for replacing thin-walled cold-formed steel in the prior art, and in the machining process of the steel channels, only welding is needed. In this way, the machining processes are reduced, production efficiency is improved, and meanwhile the production cost is reduced; the thickness of the hot-rolled light steel channels is much larger than that of the thin-walled cold-formed steel, so that the overall corrosion allowance is increased, and the service life is prolonged.

Description

technical field

[0001] The invention relates to a roof panel of a building, in particular to a heat-insulating light-weight roof panel with a steel frame. Background technique

[0002] In modern buildings, especially in steel structure buildings, composite color steel plates are often used as roofing building materials. Color steel tiles are made of color coated steel plates, which are rolled and cold-bent into various wave-shaped profiled plates. It is suitable for the roof, wall and interior and exterior wall decoration of industrial and civil buildings, warehouses, special buildings, and large-span steel structure houses. , service life, and poor maintenance, but the production of composite color steel plates is energy-intensive and resource-intensive. friendly society.

[0003] Before this application, the applicant invented a light roof panel with steel frame heat preservation and heat insulation to solve the above problems, but there are also certain problems: most o...

Examples

Embodiment 1

[0024] Such as figure 1 with figure 2 As shown, this embodiment includes the following steps:

[0025] (A) Weld four channel steels 1 and four triangle steels 2 into a standard rectangular frame, first weld two parallel angle steels 2 on a pair of parallel channel steels 1, so that the angle steels 2 and channel steel 1 The surface forms steps;

[0026] (B) The steel mesh is welded within the rectangular frame, and the steel mesh is located in the middle of the frame;

[0027] (C) After the filling material is laid in the rectangular frame, the roof panel can be formed, and the filling material is filled between the two triangle steels 2 to form a plane, and the angle steel 2 forms a step with the surface of the rectangular frame, and the two adjacent roof panels The steps form recesses for caulking the gaps between the roof panels. During production, build a step first, the width of the step matches the distance between the two supports on the frame, lay a plastic film o...

Embodiment 2

[0029] Such as figure 2 As shown, this embodiment is based on Embodiment 1. The channel steel 1 in the step (A) includes an upper surface and a lower surface parallel to each other, and a side surface connecting the upper surface and the lower surface. The upper surface of the channel steel 1 The surface, the side surface and the lower surface are connected sequentially.

[0030] One side of the rectangular frame in the step (A) is a plane, on which a pair of channel steel 1 is welded on the surface of the angle steel 2, one side of the triangle steel 2 is located in the plane of the frame, and the other side is perpendicular to the plane of the frame.

[0031] In the step (A), the height of one pair of the four channel steels 1 is greater than that of the other pair, and the channel steel 1 with the larger height protrudes from the channel steel 1 with the smaller height to form two supporting parts. In order to protect the filling material from external force and prevent t...
