Abstract

The utility model discloses a profiling metal roofing board style of calligraphy of falling T-shaped support pertains to the field of building roof works technical, and the technical matters that solve is the little wabbler tip of present die mould metal roofing board support, fish tail metal roofing board in the roofing expands with heat and contract with cold the frequent slip process that results in. The characteristic of this utility model lies is in: the both ends tip of the little wabbler in support upper end is smooth curved surface in succession. The positive effect is: the structure is simple, only does simple improvement to the prior art, change 90 degree right angles in the cross-section and for smooth curved surface in succession, make the little wabbler of being connected with the roof boarding in upper end smoothly not have edges and corners in succession, reach the effect that the fish tail was avoided to the protection roof boarding. This utility model is applicable to the template roof boarding of upright lockstitching a border of lockstitching a border and connecting by the machinery machine of lockstitching a border.

Description

A kind of die mould metal roofing board font of falling T bearing

Technical field

The utility model relates to the roof building field of engineering technology, particularly relates to a kind of die mould metal roofing board font of falling T bearing.

Background technology

In recent years, along with the development of China's steel building, the die mould metal sheet is used in a large number as the containment system of steel building.At present, increasing building roof has used the die mould metal roofing board, at present for the metal Roof that specific (special) requirements is arranged, adopts upright lock seaming template usually, with metal support this type of metal roofing board is installed.

In the prior art, described metal support is inverted T shape, presses Len req cutting intercepting during use, and roof panel meshes together by the mechanical cap seaming machine of special use and the little wabbler of inverted T shape bearing upper end.Winter severe cold, summer are exposed to the sun, and some continental climate area day and night temperature is very big because inverted T shape bearing two ends cutting part is 90 ° of right angles, expand with heat and contract with cold cause metal roofing board along support edges along slip.In frequent sliding process, 90 ° of right-angle sides can scratch metal roofing board, can scratch roof panel when serious, make roof panel produce seepage, influence its function of use.

The utility model content

The die mould metal roofing board font of the falling T bearing that provides a kind of two ends to be smooth surface is provided the purpose of this utility model, overcomes prior art and causes the shortcoming that scratches metal roofing board even cause the roof panel seepage.

For achieving the above object, the technical scheme of employing is: a kind of die mould metal roofing board font of falling T bearing, it is characterized in that: the end, two ends of little wabbler is the smooth and continuous curved surface.

The downward 45 ° of slopes of end, the two ends band of described little wabbler.

Compared with prior art; the utility model has the advantages that: simple in structure; only prior art is done simple the improvement; the end, two ends of the little wabbler of bearing changed into by 90 ° of right angles, cross section be the smooth and continuous curved surface; make the two ends smooth end of the little wabbler of bearing that is connected with roof panel not have corner angle continuously, reach and protect roof panel to avoid the effect that scratches.The utility model is applicable to the upright lock seaming template roof panel that connects by mechanical cap seaming machine lock seaming.

Description of drawings

Below the utility model is described in further detail by description of drawings and the specific embodiment.

Fig. 1 be the utility model seat structure and with the connected mode schematic diagram of roof panel;

Fig. 2 is a seat structure schematic diagram (amplification) among Fig. 1;

Fig. 3 is that Fig. 2 A is to structural representation (prior art: two end sections are 90 ° of right angles);

Fig. 4 is that Fig. 2 A is to structural representation (the utility model: the downward 45 ° of slopes of two end section bands).

Among the figure, 1,2-die mould metal roofing board; 3-inverted T shape bearing; The little wabbler of 4-; 5-90 ° of right angle; The downward 45 ° of slopes of 6-.

The specific embodiment

Fig. 1 be the utility model seat structure and with the connected mode schematic diagram of roof panel, Fig. 2 is a seat structure schematic diagram (amplification) among Fig. 1, Fig. 3 be prior art Fig. 2 A to structural representation, the two ends end cross-sectional that illustrates little wabbler is 90 ° of right angles.As shown in Figure 1 as seen, die mould metal sheet metal support 3, length meshes together by upright lock seaming and the inverted T shape bearing 3 of mechanical cap seaming machine (not shown) with described

roof panel

1 and 2 by required intercepting cutting during use, and die mould metal roofing board 1 and die mould metal roofing board 2 are used to be connected.

The inverted T shape bearing of a kind of die mould metal roofing board of the utility model is characterized in that: the end, two ends of the little wabbler 4 in described bearing 3 upper ends is the smooth and continuous curved surface.The utility model embodiment see Fig. 4: the downward 45 ° of slopes of end, the two ends band of the little wabbler 4 of inverted T shape bearing.

As seen from the figure, the utility model is not only simple in structure, and because the end of described little wabbler 4 is circular-arc smooth and continuous curved surface, and smooth surface does not have corner angle continuously, therefore can not scratch roof panel 1.

Claims

1. the die mould metal roofing board font of falling T bearing, it is characterized in that: the end, two ends of little wabbler (4) is the smooth and continuous curved surface.

2. according to the described a kind of die mould metal roofing board font of the falling T bearing of claim 1, it is characterized in that: the downward 45 ° of slopes of end, two ends band (6) of described little wabbler.
