Background technology
At present in large-scale large span public building maintenance system, metal Roof system is mostly used.In metal Roof system
The connection of fixed seat and roof boarding is generally divided into following several forms:
(1) the scalable connection of fixed seat and roof boarding cohesion style.Such as standing seam roof slabs system, feature is roofing
Plate retractable.Disadvantage is is not involved in the occlusion of roof boarding due to fixed seat, and panel cross section property is weaker, in application process
In easy to produce high wind effect under raised the case where.Roof boarding and the prolonged and repeated friction of hold-down support, are also easy to produce destruction.By
It freely stretches in panel, is not suitable for the construction of roofing top corollary system.
(2) the telescopic connection of fixed seat and roof boarding biting connecions.Such as 360 degree of seam roof slab systems.Its feature is
Roof boarding is scalable within the scope of certain length.Fixed seat participates in the occlusion of roof boarding, and wind resistance waterproof ability is stronger.Disadvantage is plate
Long limited, generally 40 meters hereinafter, and the more difficult roofing for adapting to Curvature change complexity.
(3) connection of fixed seat and roof boarding welded type.Its feature is that fixed seat is connect with roof boarding by welding manner
Together, wind resistance waterproof ability is stronger.Disadvantage, which is dilation matrices, to be discharged, and welding quality requirement is high, in by air
The factors such as impurity, voltage and current stability, the purity of cooling water influence, it is more difficult to control construction quality.It need to continuously construct, no
The operation of energy large area, speed of application is slow, is not suitable for the installation of the mating decorative system in roofing top.
Utility model content

The range of type protection.
As depicted in figs. 1 and 2, the utility model provides a kind of metal roofing board wind resistance fixing device, by connecting spiral shell
Bolt is fixed on purlin, and fixing device includes hold-down support 1 and panel bite film 2, and hold-down support 1, which is equipped with to fix with purlin, to be connected
The connecting hole 3 connect, as shown in Figure 3;Panel bite film 2 is connected by forming relative rotation between tightening connection part 4 and hold-down support 1
It connects, the molding panel occlusion portion 21 on the top of panel bite film 2, panel occlusion portion 21 stretches out the upper end of hold-down support 1.Panel is stung
Conjunction portion is for being engaged roof boarding riblet, as shown in Figure 5 and Figure 6, after the completion of hold-down support 1 is engaged with roof boarding 10, roof boarding 10
It closely connect and does not produce relative sliding with hold-down support 1.The fixed part 5 of panel bite film 2 and the hold-down support 1 under it is spiral shell
It tethers and connects, roof boarding 10 passes through roof boarding 10 and panel bite film often due to the stroke that the factors such as temperature change generate across interior
2 common fine rotations deform come the problem of digesting, not will produce stress concentration, restriction plate is not long, avoid roofing panel with
Friction causes fatigue rupture for a long time between hold-down support.
Due to panel bite film 2 can fine rotation, be arc modeling after the occlusion of roof boarding rib of slab, can positive, reversed curved arc,
And multiple and different radiuses can be fitted with the smooth covering on a piece of roof boarding, realizing Modeling of Complex Surface, have excellent
Good wind resistance, watertightness and air-tightness.
0~20 ° of relative rotation can be formed in the utility model between panel bite film and hold-down support, is produced convenient for digestion
Raw stress.
As shown in Figures 2 and 3, hold-down support 1 includes the first support plate 11 and the second support plate 12, the first support plate 11
The upper end of upper end and the second support plate 12 forms a horizontal overall structure, in the utility model preferably by the first support plate 11 with
Second support plate 12 is formed by same steel plate bending, and the lower part of the first support plate 11 and the second support plate 12 is formed after bending
One fixation for fixed panel bite film 2 vertically is formed at the top of the fixed part 5 being fixedly connected with purlin, the second support plate 12
Plane 6, fixed pan 6 are equipped with mounting hole 7, and the tightening piece such as bolt can run through mounting hole 7 and panel occlusion on fixed pan 6
Through-hole on piece 2 realizes the mating connection of the two.
In order to make entire hold-down support that there is better support performance, it is located at the second support plate 12 of 6 lower section of fixed pan
On sequentially form the first bending part 121 and the second bending part 122, the second bending part 122 is connect with the fixed part 5.Preferably,
First bending part 121 and the second bending part 122 form right-angle structure, the medial surface of the first bending part 121 and the second bending part 122
Equipped with ribs 8.
The utility model also forms a supporting oblique surface 9 for being used to support roof boarding on the top of the first support plate 11, fixed
Special oblique shoulder moulding is formed after bearing and roof boarding occlusion, while also on the medial surface of supporting oblique surface 9 and being disposed below
The first support plate 11 medial surface be equipped with ribs 8.Hold-down support to roof boarding it is close connection and secure support, and
Roof boarding itself has the characteristics that sufficiently strong cross sectional moment of inertia and is unlikely to deform, and ensures its deformation generated under Action of Wind pressure
It is digested in board bottom and stile, does not interfere with being engaged between the big rib of roof boarding and riblet position and panel occlusion portion, to big
Enhance wind uplift resistance, such as Fig. 7 greatly.
As shown in Figure 1 and Figure 4, it threads off to further place roof boarding, the panel occlusion portion 21 of the utility model is in circle
Arcuate structure, end form the wind resistance tabletting 211 for being engaged roof boarding riblet.The riblet of roof boarding is being placed in arc knot
When the panel occlusion portion position of structure, then wind resistance tabletting 211 is pressed together on to the riblet position of roof boarding, roof boarding is prevented to thread off.
Wind resistance tabletting 211 in the utility model is locally extended by the free end of panel occlusion portion 21, is formed in panel occlusion
The central region in portion 21 can be interrupted structure.
Since fixing device limits freely stretching for roof boarding, it is arranged in auxiliary facilities such as the decorative panels on roof boarding top
When being snapped connection by rib of slab, position will not change, and ensure that the structure safety of corollary system.Meanwhile fixed decoration
Rib of slab buckle and the platform position at the top of roof boarding and fixing device of the corollary systems such as plate are in close contact, relative to traditional straight
The connection type of vertical lock seaming metal Roof fixture, greatly improves bearing capacity and structural safety performance.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
Among changing still in the scope of protection of the utility model.
