Abstract
The utility model discloses a double-layer flange, the double-layer flange comprises a flange. The utility model is characterized in that the double-layer flange comprises an upper flange and a lower flange, the upper flange is connected with the lower flange via a supporting tube to form a bigendup inverted cone; the double-layer flange also comprises a supporting bar body which is connected with the upper side of the upper flange, and the diameter of the screw distribution circle of the lower flange is less than the diameter of the bottom of the rod body. The double-layer flange solves the difficult problem that the tube body with large diameter is installed on the basic object with smaller diameter. The double-layer flange is suitable for installing devices with a tower shape such as a communication tower on the top of the building.
Description
Technical field
The utility model relates to a kind of flange.
Background technology
Tend to run into the problem on load-bearing basis, building when on roof, the communications tower kind equipment being installed in the past, because the special construction of roof only allows that generally communications tower equipment is carried on the load-bearing pillar in building, but when the diameter of load-bearing pillar during than communications tower equipment basic much smaller, just communications tower equipment can not be installed on roof, can only adopt footless simple and easy Guywire tower, neither attractive in appearance also insecure.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provide a kind of being suitable for that the major diameter body is installed in than a kind of connection transition Double-layer flange on the basic thing of minor diameter, to solve a difficult problem of on roof, installing as tower-type equipments such as communications tower.
The purpose of this utility model is to realize by following major technique means: a kind of Double-layer flange, comprise flange, and be characterized in that it comprises a upper flange and a lower flange, upper and lower flange is by a stay pipe up big and down small reverse taper that is formed by connecting; Comprise that also one is connected in the support rod body above the described upper flange, the screw distribution circle diameter of described lower flange is less than the diameter of body of rod bottom.
In the above-mentioned Double-layer flange: the neighboring of described stay pipe is provided with plurality of strengthening ribs.
By above-mentioned technological means, the utility model Double-layer flange has solved the diameter difficult problem more much bigger than load-bearing pillar of support rod body when on roof tower-type equipment being installed.
Description of drawings
Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing and preferred embodiment:
Fig. 1 is the perspective view of the utility model Double-layer flange;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is the perspective view of the Double-layer flange of band reinforcing rib.
The specific embodiment
Please referring to Fig. 1-3, by seeing among the figure, a kind of Double-layer flange 10 provided by the utility model, it comprises a upper flange 11 and a lower flange 13, upper and lower flange connects by a stay pipe 12, the top of upper flange 11 is connected with the support rod body 20 of a communications tower equipment by this upper flange, and the screw 1 30 distribution diameter of a circles of this lower flange 13 are less than the diameter of the bottom of the body of rod 20, and forms a up big and down small reverse taper Double-layer flange structure.The support rod body 20 of communications tower equipment can be installed on the load-bearing pillar in building by this lower flange 13.Shown in Figure 2, be plurality of strengthening ribs 14 to be set in the neighboring of stay pipe 12, can be the 4-12 bar, make Double-layer flange firmer.
So just, solved when on roof, installing, the major diameter body has been installed in than the difficult problem on the basic thing of minor diameter as tower-type equipments such as communications tower.One the utility model Double-layer flange has played the effect that connects transition.By the roof communications tower equipment that the utility model is installed, firmly light and handy, outward appearance is coordinated attractive in appearance.
The utility model not only can be used in the installation of roof communications tower, the major diameter body is installed in than the similar field on the basic thing of minor diameter all can uses.
