Description

Novel clerestory roof plate structure

Technical Field

The invention relates to the technical field of buildings, in particular to a novel clerestory roof panel structure.

Background

People usually set ventilation and lighting clerestory between the flat roofs of public buildings and large-span plants. The existing method for laying the dormer roof is to fix the roof boards on two slopes on the purline of the roof by self-tapping screws and then to perform waterproof treatment on the roof boards by using ridge cover plates and water-stop adhesive tapes. The structure has poor durability, is easy to seep water, has higher requirements on construction and has higher cost.

Disclosure of Invention

The invention provides a novel clerestory roof plate structure which is stable and reliable in structure.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a novel dormer roofing plate structure which characterized in that: the prefabricated steel structure comprises a clerestory steel beam, a purline supporting plate, purlines and a roof panel, wherein the purline supporting plate and the clerestory steel beam are oppositely arranged and connected with each other and are adjacent to each other, and the roof panel is fixed on the purlines; the roof panel comprises a first panel and a second panel which are integrated, and the gradient of the first panel and the gradient of the second panel are less than 3%.

Preferably, the steel frame columns are arranged on the steel beams of the clerestory and are fixed on the main steel frame roof beams.

Preferably, the purlins are fixed on the purlin supporting plates through bolts.

Preferably, the purlins are arranged on the clerestory steel beams at intervals, and the roof panels are fixed on the purlins through self-tapping bolts.

Preferably, the purlin planking is welded on the clerestory steel beam.

Preferably, the purlines are U-shaped sections, the face plates of the purlines are connected with the purline supporting plates, rib plates are arranged on the purline supporting plates, and one sides of the rib plates abut against the upper end faces of the clerestory steel beams.

Preferably, baffles facing one side of the main steel frame roof girder are arranged at two ends of the clerestory steel girder.

Preferably, the roof panel is made of HV820 type plates.

In summary, compared with the prior art, the invention has the advantages that: the integrated roof plate is arranged on the roof purline, so that the installation is rapid and the waterproof performance is good; the slope of the roof panel is less than 3 percent, and the panel with smaller wave height is adopted, thereby greatly reducing the water leakage risk at the ridge and reducing the cost of later-period roof maintenance.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The reference numbers in the figures are as follows:

1. the steel roof structure comprises a clerestory steel beam, 2 purlin supporting plates, 3 purlins, 31 rib plates, 4 roof panels, 41 first plate surfaces, 42 second plate surfaces, 5 steel frame columns, 6 main steel frame roof beams and 7 baffle plates.

Detailed Description

The invention will be further elucidated with reference to an embodiment in the drawing.

The prefabricated steel structure comprises a clerestory steel beam 1, a purline supporting plate 2, purlines 3 and a roof panel 4, wherein the purline supporting plate 2 and the clerestory steel beam 1 are oppositely arranged and are connected with the adjacent purlines 3, and the roof panel 4 is fixed on the purlines 3. Roof panel 4 includes first face 41 and second face 42 of an organic whole, and the slope of first face 41 and second face 42 is less than 3%. This clerestory adopts integrative roof boarding 4 to set up on roofing purlin 3, and the installation is swift, and waterproof nature is good, need not other connections and waterproof construction, and stability is high. The slopes of the first board surface 41 and the second board surface 42 are both smaller than 3%, and the board type with smaller wave height is adopted, so that the water leakage risk at the ridge is greatly reduced, and the cost of later-period roof maintenance is reduced. Roof panel 4 is of a lower wave height version such as HV820 sheet.

The clerestory steel beam 1 is provided with steel frame columns 5, the steel frame columns 5 are fixed on the main steel frame roof beam 6, and the number of the steel frame columns 5 is two and is symmetrically arranged relative to the clerestory steel beam 1. Purlin 3 passes through the bolt fastening on

purlin layer board

2, and 3 tip of purlin sets up two bolt holes with purlin layer board 2 department of being relative. Purlins 3 are arranged on clerestory steel beam 1 at intervals, roof boarding 4 is fixed on purlins 3 through self-tapping bolts, and the bolt joints can be sealed through sealant.

Purlin layer board 2 welding sets up on dormer girder steel 1. Purlin 3 is the U section bar, and purlin 3's panel and purlin layer board 2 rigid coupling are equipped with floor 31 on the purlin layer board 2, and floor 31 offsets with the 1 up end of clerestory girder steel on one side, and the bolt hole symmetry on the purlin layer board 2 sets up in floor 31 both sides. The quantity of purlin 3 is three, and two purlin 3's of lateral part opening sets up relatively, and the clerestory steel roof beam 1 both ends are equipped with baffle 7 towards 6 one side of main steelframe roof beam to block the rainwater. The baffle 7 can be a beam structure with a rectangular section, so that the structural strength is improved while rainwater is blocked; the baffle 7 may also be of an arc-shaped plate structure, the arc-shaped opening of which faces one side of the steel frame column 5.

The above description is only for explaining the present invention and making the present invention complete, but not limiting the present invention, and the skilled in the art can make modifications without inventive contribution to the present embodiment as required after reading the present specification, and these are all modifications without inventive contribution, but are protected by patent laws within the scope of the claims of the present invention.
