Abstract
The present invention relates to the built-in mounting platform of a kind of bridge tower lightning rod and the method with its installation lightning rod, bridge is cable stayed bridge, suspension bridge, mounting platform is formed by there being the inside and outside sleeve pipe of certain altitude, in the ordinary steel of outer tube, pipe to be preced with bridge tower tower by shear connector and to be connected, the common steel tube upper and lower end welded steel pipe junction plate of inner sleeve, stainless steel external screw thread steel pipe, stainless steel external screw thread steel pipe connects lightning rod bed plate, handle junction plate, mounting handle; Inside and outside casing threads connects.Mounting method: the pre-buried outer tube being welded with shear connector, placing of concrete, lightning rod is fixed on lightning rod bed plate, and rotation lightning rod and inner sleeve are through outer tube, and lightning rod stretches out and puts in place.Adopt the installation of the lightning rod of the present invention's towering bridge tower and later maintenance just can complete in tower, avoid the outer work high above the ground of tower; Meet again the requirement of bridge tower view, do not increase the component outside bridge tower tower hat; Steadiness and operability good; Install simple, it is convenient to safeguard.
Description
Technical field
The present invention relates to a kind of bridge, mainly the method for cable stayed bridge, the built-in mounting platform of Construction of Pylon of Long Span Suspension Bridge lightning rod and installation lightning rod thereof.
Background technology
The lightning protection device that the bridge tower structure that lightning rod is cable stayed bridge, suspension bridge is towering must be arranged.Traditional lightning rod is installed needs bridge tower top to have a larger platform space, and constructor wants to arrive this mounting platform operates, and which limits the moulding of bridge tower.And along with people are to the more and more attention of bridge construction aesthetics, bridge tower structure itself, except meeting structure stress needs, also passes through the moulding imparting mechanism of self in addition with function attractive in appearance.
Usu, black bear island, Heilongjiang Province bridge is positioned at Fuyuan delta, Heilongjiang Province (also known as black bear island), is located in the eastern pole of China, is described as " east first bridge ".Because geographical position is special, bridge tower tower hat is set to the form of heronsbill, and plastic simplicity is attractive in appearance.And tower is preced with moulding attractive in appearance and is arranged the installation and maintenance of lightning rod and cause inconvenience.What traditional lightning rod platform arranged that way can destroy bridge tower itself enriches the landscape effect that distinctive creation brings.Need to design a kind of method that bridge tower headspace stenosis installs lightning rod.
Summary of the invention
The object of the invention is for above-mentioned present situation, aim to provide a kind of installation simple, it is convenient to safeguard, is suitable for bridge tower headspace narrow, installs and safeguard the built-in mounting platform of bridge tower lightning rod need do not implemented from bridge tower outside and the method for installing lightning rod thereof.
The implementation of the object of the invention is, the built-in mounting platform of bridge tower lightning rod, and by there being the inside and outside sleeve pipe of certain altitude to form, in the ordinary steel of outer tube, pipe to be preced with bridge tower tower by shear connector and to be connected, and outer tube is upper and lower is welded with stainless steel inner thread steel pipe; The upper and lower steel pipe connecting fishplate bar that passes through of the common steel tube of inner sleeve is together with stainless steel external screw thread steel-pipe welding, and upper stainless steel external screw thread steel pipe connects lightning rod bed plate, lower stainless steel external screw thread steel pipe connecting handle junction plate, welded and installed handle on handle junction plate; Stainless steel external screw thread steel pipe is threaded with stainless steel inner thread steel pipe, and described bridge is cable stayed bridge, suspension bridge.
The method of lightning rod is installed with the built-in mounting platform of bridge tower lightning rod, first the outer tube being welded with shear connector is embedded in bridge tower tower hat, placing of concrete again, lightning rod is fixed on the lightning rod bed plate of inner sleeve, then lightning rod and inner sleeve are passed outer tube by the method rotating screw thread, lightning rod stretches out and puts in place; Described bridge is cable stayed bridge, suspension bridge.
Outer layer pipe of the present invention is preced with bridge tower tower and is connected by shear connector; Inside and outside sleeve pipe has certain height, to increase himself as the rigidity of platform, the steadiness be connected with bridge tower and operability; Adopt stainless steel, to ensure the convertibility of durability and the lightning rod be threaded.
The present invention had both overcome towering bridge tower lightning rod and has installed and safeguard the difficulty changed, and installation and later maintenance just can complete in tower, avoided the outer work high above the ground of tower; Meet again the requirement of bridge tower view simultaneously, do not have additionally to increase the component outside bridge tower tower hat because of lightning rod.
The present invention installs simply, and it is convenient to safeguard, is suitable for bridge tower headspace narrow, installs and safeguards the situation being all not easy to implement from bridge tower outside.
The present invention adopts at Usu, black bear island, Heilongjiang Province bridge, achieves and well uses effect.

Detailed description of the invention
With reference to Fig. 1-4, the built-in mounting platform of bridge tower lightning rod of the present invention is made up of inside and outside sleeve pipe, and in the ordinary steel of outer tube 1, pipe is preced with 12 by shear connector 4 and bridge tower tower and is connected, and outer tube upper and lower end is welded with stainless steel inner thread steel pipe 5.Common steel tube 6 upper and lower end of inner sleeve 2 is welded together by steel pipe connecting fishplate bar 9 and stainless steel external screw thread steel pipe 7, upper stainless steel external screw thread steel pipe connects lightning rod bed plate 8, lower stainless steel external screw thread steel pipe connecting handle junction plate 11, welded and installed handle 10 on handle junction plate; Stainless steel external screw thread steel pipe 7 is threaded with stainless steel inner thread steel pipe 5.
The inside and outside sleeve pipe of certain altitude, refers to the rigidity that can meet inside and outside sleeve pipe platform, height that firm and lightning rod is installed, has enough rigidity, steadiness and operability to make this structure.The minimum diameter of stainless steel inner thread steel pipe 5 and stainless steel external screw thread steel pipe 7 is determined according to lightning rod specification.
The method of lightning rod is installed with the built-in mounting platform of bridge tower lightning rod, first the outer tube 1 being welded with shear connector 4 is embedded in cable stayed bridge or Construction of Pylon of Long Span Suspension Bridge tower hat 12, placing of concrete again, lightning rod is fixed on the lightning rod bed plate 8 of inner sleeve 2, then lightning rod and inner sleeve 2 are passed outer tube by the method rotating screw thread, lightning rod stretches out and puts in place.When need change, derotation lightning rod and inner sleeve, lightning rod and inner sleeve are fallen, and can change, and it is convenient to change.
The present invention had both overcome towering bridge tower lightning rod and has installed and safeguard the difficulty changed, and installation and later maintenance just can complete in tower, avoided the outer work high above the ground of tower; Meet again the requirement of bridge tower view simultaneously, do not have additionally to increase the component outside bridge tower tower hat because of lightning rod.
The present invention installs simply, and it is convenient to safeguard, is suitable for bridge tower headspace narrow, installs and safeguards the situation being all not easy to implement from bridge tower outside.
The present invention adopts at Usu, black bear island, Heilongjiang Province bridge, achieves and well uses effect.
