Detailed Description

The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.

As shown in fig. 1-7, the high-precision steel purline of the installation structure comprises a C-shaped steel 10, 2 groups of perforated plate units 1 which are respectively arranged at two sides of the C-shaped steel 10 and are used for connecting a roof truss a, and a cable stayed plate 2 which is arranged on the outer side surfaces of the perforated plate units 1 and the C-shaped steel 10.

In this embodiment, the materials of the C-shaped steel 10, the perforated plate unit 1 and the inclined pull plate 2 are all conventional carbon steel, i.e. structural steel commonly used in building construction, and the latter two may be integrally formed with the C-shaped steel 10 or welded in a later stage.

The length direction of the section shape of the C-shaped steel 10 is horizontal and is in lying state, and the perforated plate units 1 are arranged on two sides of the C-shaped steel, so that the installation structure of the steel purline is relatively stable, namely, the installation position accuracy is high.

Furthermore, it is possible to provide a device for the treatment of a disease. The cable-stayed plate 2 is used for reinforcing the C-shaped steel 10 and the perforated plate unit 1, so that the structural shape of the steel purline is not easy to deflect or deform, namely the structural accuracy of the steel purline is high.

Finally, the steel purlines are firstly erected on the two inclined planes of the roof truss a, then roofing materials c are paved on the steel purlines, and finally the roof structure of the steel structure house is approximately completed.

The perforated plate unit 1 includes a fixing plate 101 provided on the outer side surface of the C-section steel 10 and welded to the roof truss a, and a fixing hole 102 provided on the fixing plate 101 for mounting the bolt b.

In this embodiment, the preset position on the roof truss a is aligned with the circular hole of the fixing hole 102, and the bolt b connects the fixing hole 102 and the circular hole, so as to ensure that the screwing function of the perforated plate unit 1 is effective.

In addition, the welding seams d are arranged on 3 sides of the fixing plate 101, so that the welding function of the perforated plate unit 1 is ensured to be firm enough.

The cable-stayed plate 2 is a two-section upward bending plate.

The usual cable-stayed plate pattern in the prior art is a simple flat plate, whereas in this embodiment the cable-stayed plate 2 is bent upwards in order to make room for a sufficient dismounting and mounting of the bolts b.

The bolts b are required to be detached and installed by an operator to reach under the inclined pull plate 2, so that the preferred operation position of the operator is under the roof truss a.

The number of the cable-stayed plates 2 is equal to that of the perforated plate units 1.

In this embodiment, the perforated plate units 1 are a plurality of separate plate bodies, which are uniformly spaced from each other, and the 1 st position structure pattern of the diagonal draw plate 2 is the same as the perforated plate units 1, but is also discontinuous, and corresponds to each other one by one.

One of the advantages of this approach is the saving of material for the diagonal tension plate 2, and one of the disadvantages is the inability to further improve the structural integrity of the steel purlin.

All the perforated plate units 1 on one side are arranged on 1 cable-stayed plate 2.

In this embodiment, the cable-stayed plate 2 with the above-mentioned position structure pattern is the 2 nd choice, so that the advantages and disadvantages are exactly opposite to those of the 1 st choice, and the structural integrity and the supporting strength of the steel purline can be obviously improved.

In addition, the continuous cable-stayed plate 2 also increases the degree of trouble of assembling and disassembling the bolts b appropriately as compared with the independent and separated cable-stayed plates 2.

The inner top surface of the C-shaped steel 10 is also provided with an intermediate support plate 3 for connecting with a roof truss a.

In this embodiment, if the aspect ratio of the cross-sectional shape of the C-section steel 10 is large, the advantage of the intermediate support plate 3 is more remarkable, and the downward bending deformation of the intermediate plate body of the C-section steel 10 can be further avoided.

In this case, the intermediate support plate 3 alone may be a welded roof truss a or may be merely supported on the latter.

The middle supporting plate 3 is also provided with a bottom plate 4 for welding the roof truss a.

In this embodiment, the effective length of the welding mode of the middle support plate 3 can be increased by the bottom plate 4, so that the welding firmness is further enhanced, and the possibility is provided for other subsequent installation modes.

The number of the bottom plates 4 is equal to that of the intermediate support plates 3.

In this embodiment, the combination of the middle support plate 3 and the bottom plate 4 is the same as the combination of the perforated plate unit 1 and the inclined pull plate 2, the former is separately and independently arranged, and the latter is either continuous or independent, and both the two methods have advantages and disadvantages.

All the intermediate support plates 3 are provided on 1 of the bottom plates 4.

In this embodiment, 1 bottom plate 4 is provided, that is, the above-mentioned continuous arrangement mode, which can at least strengthen the structural integrity and strength of the steel purline.

The bottom plate 4 is also provided with a bolt hole 5.

In this embodiment, the width of the fixing plate 101 and the width of the bottom plate 4 can be larger than the width of the steel plate of the roof truss a, 3 welding seams can be obtained, and the bottom plate 4 can be optionally welded and screwed.

Therefore, further, the round size of the bolt hole 5 is approximately equal to that of the fixing hole 102, so that the two bolts can be used universally, and the steel purline is more convenient to install.

Of course, when the bolts are attached to or detached from the bolt holes 5, the operations can be performed only under the roof truss a, and if the operator is above, the difficulty of the hand stretching operation is too great.

The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
