Description

Upright lock seaming metal Roof structure

Technical field

The utility model is a kind of roof structure, particularly a kind of upright lock seaming metal Roof structure.

Background technology

Traditional upright lock seaming metal Roof structure, roofing is formed by T type bearing 2 overlap joints by roof panel 1, at first T type bearing 2 is fixed on the room beam, roof panel 1 is buckled on the T type bearing 2 then, 1 of roof panel leans on the crimping on the rib to overlap mutually, carry out the machinery lock seaming at last and be integral, as shown in Figure 1.

Traditional upright lock seaming metal roofing board, section is the tank type, its bottom surface and two stile near vertical, the crimping of stile end is level and smooth arc, as shown in Figure 2.The panel of this form has following shortcoming: 1) slab strength is low, and bearing capacity is little, need encrypt the defective that just can remedy the panel member strength deficiency with the keel spacing; 2) panel rigidity is little, deforms horizontal and vertical easily, thereby influences architectural appearance and use, and for the less roofing of the gradient, because longitudinal strain is excessive, be easy to cause roof ponding; 3) in the panel member installation process or under the effect of wind load, can horizontal distortion often take place, can produce the alternating stresses phenomenon in the knuckle position, fatigue failure can take place in regular alternating stresses for a long time, therefore, traditional upright lock seaming plate easily folding occurs in this position, splits phenomenon; 4) the stile crimping of traditional panel is common slick and sly arc crimping, fact proved, under the promotion of wind, the Roof system of this type very easily produces capillary at the crimping place, i.e. the generation of rainwater refluence phenomenon causes the heat-insulation material of internal system destroyed,

Traditional T type bearing comprises dop 3, support column 4 and base 5, and as shown in Figure 3, the bottom surface of base 5 is flat, and dop 3 is polygon, simultaneously 4 one-tenth 90 degree in dop 3 bottoms and support column.The T type bearing of this form has following shortcoming: 1) because the moulding complexity on modern roof, room beam upper surface in the often actual engineering is not very flat, so just make and T type bearing and room beam loose contact cause unbalance stress, influence the planarization and normal use of roofing; 2) because the polygon dop of traditional T type bearing bottom becomes 90 degree with support column, so just make roofing assembly and dop skid easily, cause loosening, under the effect in the external world, safety and stability that the pulling capacity that produces such as negative blast etc. can be to influencing roofing; 3) because the bight of dop is more sharp-pointed, at the contact position of roof panel crimping and polygon dop, through the ruined phenomenon of regular meeting's generating plane plate.

Summary of the invention

The purpose of this utility model purpose is in order to overcome little, the easy defective of loosening, poor stability of yielding, the easy ponding of traditional roofing, bearing capacity, to invent a kind of novel upright lock seaming roof structure.

The purpose of this utility model realizes as follows: a kind of upright lock seaming metal Roof structure comprises roof panel and T type bearing; It is characterized in that: the section of roof panel is the tank type, and the knuckle place of stile and bottom surface is provided with the recurvation knuckle that is made of two knuckles, and the end of two stiles is respectively equipped with camber line crimping and incisura coil of wire limit; The section of the dop of T type bearing is quincunx, is that the bottom surface of base is provided with groove less than the knuckle of 90 degree between the bottom of dop and the support column, the quincunx section coupling of the section on the incisura coil of wire limit of roof panel and dop; T type bearing is by the equidistant arrangement of the width of roof panel and be fixed on the room beam, the mutual interlock of dop of incisura coil of wire limit on the roof panel and T type bearing, the camber line crimping of another roof panel is overlapped on the incisura coil of wire limit of adjacent roof panel, make both mutual structure interlocks and lock seaming, its lap-joint leaves anti-hair and inhales cavity, overlap joint goes down continuously successively, with regard to integrant roofing.

Good effect of the present utility model is as follows:

1) strength and stiffness significantly improve.

The design of recurvation knuckle is equivalent to be provided with stiffening rib to flat board, makes the strength and stiffness of roof panel be significantly improved evidence: under identical stress condition, the bearing capacity of this kind template is 1.3 times of traditional templates;

2) increase roof panel antifatigue damage capability

Roof panel replaces traditional simple fillet to handle at the knuckle place with the recurvation knuckle, makes alternating stresses occurrence positions that lateral deformation causes herein by only being distributed to different parts now at the knuckle place originally, thereby has strengthened the ability that the panel antifatigue is destroyed greatly.

3) design of recurvation knuckle makes the area that roof panel stile and bottom surface contact with T type bearing reduce, thereby has effectively avoided with T type bearing phenomenon that friction cause panel destruction taking place during telescopic slide because of roof panel under thermal stresses.

4) stop the generation of capillarity

Even rainwater roofing water under the promotion of wind is siphoned into crimping inside, also can only rests on anti-capillary cavity, and then reserve, so can not flow to the inside of roofing.

5) be less than the knuckle of 90 degree between the bottom of dop and the support column, can prevent to skid between roof panel and the dop, make roof panel and plum blossom head dop firmly lock, can not become flexible, even if under wind suction effect repeatedly, also can not destroy.

6) T type rest base is provided with groove, and what contact the purlin surface like this is pawl rather than flat board, and support force obtains than uniform distribution, so T type bearing can very firm being fixed on the roof purline, thereby is applicable to the roof structure of moulding complexity more.

7) section of dop is quincunx, makes the top of dop become slick and sly, and making has had excellent contact between roof panel crimping and the T type bearing, avoided the traditional polygon bearing in this position the destruction to roof panel.
