The flange of traditional segmentation concrete pole generally comprises gusset, flange circle, lacing wire circle and protective shroud, and its structural style is that the flange circle is located the link (two flange circles lean on together when two sections are connected), and gusset and protective shroud are located non-link end, and the gusset distributes on the same terminal surface of flange circle with connecting bolt's tip, because the gusset has occupied the spanner space of bolt, causes bolt quantity and size to be limited, and this structure is difficult for meeting the demands when needs transmit great atress.
Disclosure of Invention
The invention aims to provide a casting or forging connecting flange for a concrete rod, which can ensure that the wrench space of bolts is not limited by a rib plate, can properly increase the number of the bolts and the diameters of the bolts and improve the connection stress of the flange.
The purpose of the invention is realized by the following technical scheme:
the cast or forged connecting flange for the concrete rod is characterized by comprising a flange ring, a group of rib plates, an inner pressure bearing ring and an outer pressure bearing ring which are respectively arranged at the connecting end of the flange ring, a lacing ring arranged at the inner side of the inner pressure bearing ring, a group of lacing holes arranged along the circumference of the lacing ring, a protective ring arranged at the back of the connecting end of the flange ring, and a group of bolt holes arranged on the flange ring,
the outer pressure-bearing ring is connected with the outer circle of the flange ring, the inner pressure-bearing ring is connected with the inner circle of the flange ring, the group of rib plates are uniformly distributed along the circumference of the flange ring and connect the inner pressure-bearing ring and the outer pressure-bearing ring into a whole along the radial direction,
and each bolt hole on the flange ring is positioned in a space enclosed by two adjacent rib plates, the inner pressure bearing ring and the outer pressure bearing ring.
The rib plates are as high as the inner bearing ring and the outer bearing ring.
The overhanging end face of the retainer is straight or the inner side of the overhanging end face is provided with a chamfer.
The invention has the advantages that:
the cast or forged connecting flange for the concrete pole has a simple structure and ingenious design, can ensure that when two flanges are connected, the contact surface between the flanges is the contact of the rib plates of the two flanges and the end surfaces of the inner pressure bearing ring and the outer pressure bearing ring, the two flange rings are not in contact, the wrench space when connecting bolts on the flange rings are fastened is not limited by the positions of the rib plates, and the number of the bolts and the diameter of the bolts can be properly increased when force transmission needs to be increased.

Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 4, the cast or forged connection flange for concrete poles of the present invention is characterized by comprising a flange ring 1, a set of rib plates 2, an inner bearing ring 5 and an outer bearing ring 6 respectively provided at the connection end of the flange ring 1, a lacing wire ring 3 provided inside the inner bearing ring 5, a set of lacing wire holes 8 arranged along the circumference of the lacing wire ring 3, a retainer ring 4 provided at the back of the connection end of the flange ring 1, a set of bolt holes 7 provided on the flange ring 1,
the outer bearing ring 6 is connected with the outer circle of the flange ring 1, the inner bearing ring 5 is connected with the inner circle of the flange ring 1, the group of rib plates 2 are uniformly distributed along the circumference of the flange ring 1 and connect the inner bearing ring 5 and the outer bearing ring 6 into a whole along the radial direction,
each bolt hole 7 on the flange ring 1 is positioned in a space enclosed by two adjacent rib plates 2, the inner bearing ring 5 and the outer bearing ring 6.
The rib plate 2 is as high as the inner pressure bearing ring 5 and the outer pressure bearing ring 6.
The overhanging end face of the retainer 4 is straight or the inside of the overhanging end face is chamfered.
The invention is realized by the following scheme. The forming process of the flange is casting or forging, the flange is made of steel or aluminum alloy, and the specific structural form is as follows: the rib plates 2, the inner pressure bearing ring 5 and the outer pressure bearing ring 6 are arranged at the connecting end of the flange ring 1, the outer pressure bearing ring 6 is connected with the outer circle of the flange ring 1, the inner pressure bearing ring 5 is connected with the inner circle of the flange ring 1, the rib plates 2 are as high as the inner pressure bearing ring 5 and the outer pressure bearing ring 6, and the rib plates 2 are uniformly distributed along the circumference and connect the inner pressure bearing ring 5 and the outer pressure bearing ring 6 into a whole along the radial direction. The other end face of the flange ring 1 is not provided with a rib plate and is only connected with the guard ring 4. Be equipped with bolt hole 7 on the flange circle 1, bolt hole 7 is located between two adjacent gusset 2, also is located between interior pressure ring 5 and the outer pressure ring 6, and the spanner space of bolt does not receive the restriction of gusset 2 when two flange joint like this, can suitably increase bolt quantity and increase the bolt diameter, improves the flange joint atress. The hanging rib ring 3 is arranged on the inner side of the inner pressure bearing ring 5 and is in a position which is overlapped with the flange ring 1 to a certain extent, so that the stress of the hanging rib ring 3 is directly transmitted to the flange ring 1, and hanging rib holes 8 which are uniformly distributed along the circumference are formed in the hanging rib ring 3 and are used for being connected with steel bars in the concrete rod body. The outward ends of the retainer 4 may be straight or may be chamfered on the inside to reduce stress concentration. The joints of the rib plates 2 and the inner bearing ring 5, the rib plates 2 and the outer bearing ring 6, and the rib plates 2 and the flange ring 1 can be provided with process fillets, so that the processing and the forming are convenient, and the stress concentration is avoided.
According to the structure, when two flanges are connected, the contact surfaces between the flanges are the contact of the rib plates 2 of the two flanges and the end surfaces of the inner pressure bearing ring 5 and the outer pressure bearing ring 6, the two flange rings 1 are not in contact, the wrench space when connecting bolts on the flange rings 1 are fastened is not limited by the positions of the rib plates, and the number of the bolts and the diameter of the bolts can be increased properly when force transmission needs to be increased.
