Problems solved by technology

The disadvantage of the 475 plate type is that it is not an integer, so it is inconvenient to install
[0006] Furthermore, most of the roof panel systems currently on the market adopt the 360° upright seam form (the nailed board is not good for waterproofing, and the seam board is more conducive to waterproofing), and accessories (such as anti-corrosion wind clamp 6), fixed by the fixing piece (screw 7), the irregular arrangement of the roof panels 4 directly leads to the irregularity of the wind-resistant clamp installation hole 52 on the upper flange 51 of the purlin of the sandalwood bar 6 Arrangement, which increases the types of purlins, affects the efficiency and qualification rate of purlin processing and manufacturing, and also increases the difficulty of installation, potentially increasing the cost of the project

Embodiment 1

[0031] Such as Figure 4 For the profiled roofing steel plate profile shown in Embodiment 1 (namely, the 500 profile 2'), the effective width S' of the 500 profile 2' is 500 mm. The design of 500mm follows the provisions of the "National Building Modulus Coordinated and Unified Standard", and 500mm is 5 times the basic building modulus. 500 plate type 2' is a plate type made of color-coated steel plate or galvanized steel plate, which has the function of anti-rust and waterproof and prolongs the service life. The thickness r of the plate shape is 0.5-1 mm (preferably 0.5-0.7 mm), and the plate shape is not easy to break during the production process, and is also easy to form.

[0032] The cross-section of the end portion of the plate shape has a stepped structure 24'. The left end of the plate is provided with a hook 25', and the right end of the plate is provided with a top hook 26' matching the shape of the hook 25'. The adjacent 500 plate 2' is caught by the hook 25' and ...

Embodiment 2

[0036] Further, as another embodiment of the first embodiment, the effective width S' of the second embodiment is 500 mm, and the expanded width is 625 mm, which results in different sizes of the seams. The distance from the top of the hook 25' to the bottom of the plate H1=83mm, and the distance from the top of the top hook 26' to the bottom of the plate H2=81mm. For other structures of the second embodiment, refer to the first embodiment.

Embodiment 3

[0038] Such as Figure 5 Example threeThe roof shown includes 500 plate types 2'. In this embodiment, when the column distance D is 6000 mm, the center of the left end 500 plate type 21' located at the left end, the center of the hole group of the purlin supporting plate and the center of the first roof beam 11 Corresponding to the center A-A, the distance between the left end edge of the left end 500 plate type 21' and the center A-A is equal to the distance between the right end edge of the left end 500 plate type 21' and the center A-A, and the distance is T1, which is 250mm; The middle 500 plate type 22' connected by the two roof beams 12 has a distance T2 of 250 mm from the left edge of the center B-B of the second roof beam 12, and a distance T3 of 250 mm from the center B-B of the second roof beam 12 of the right end edge; and The right end 500 plate type 23' connected to the third roof beam 13 has a distance T4 of 250 mm from the left end edge to the center C-C of th...

Abstract

The invention discloses a profiled steel sheet structure for roofs. The profiled steel sheet structure is 500mm in effective width S'. Through the structure, waste of materials, manpower and time caused by shearing steel sheets is avoided; in practical laying, profiled roof boards of the profiled steel sheet structure are regularly formed in standard-span arrangement; further, the irregular form is still displayed in mounting of windproof clamps and the like for roof panels and production benefit is improved.

Description

technical field [0001] The invention relates to the field of steel structure engineering in the construction industry, in particular to a roof profiled steel plate structure. Background technique [0002] Such as figure 1 As shown, in recent years, with the increasing number of construction steel structure projects in China, profiled steel plates have also been widely used in the enclosure system of light steel structure workshops. Can be used for non-erosion, weak erosion and moderate erosion roof1 and wall. [0003] Profiled steel plates are divided into different plate types according to the design of the effective width. The commonly used plate types on the market reflect the design principles of safety, applicability and economy. For example, 475 plate type 2, the effective width S of the 475 plate type 2 is 475mm, and the unfolded length of the 475 plate type 2 is 600mm, and 600mm is a common width of coil raw materials, so that raw materials can be directly used in ...
