Description
Technical field
The invention belongs to spherical tank assembling technical field, more particularly on a kind of spherical tank pole inner top platform support meanss
And building method.
Background technology
As petrochemical industry spherical storage tank volume constantly maximizes, 3000m3Spherical tank application above is increasingly popularized.Ball
Tank is formed by polylith spherical shell valve welding, and the site operation groundwork amount of large-size spherical tank is to assemble and weld, and sphere welding
Workload major part is completed at the scene.Accordingly, it would be desirable to build construction operation platform in the inside and outside portion of spherical tank, enable an operator to lean on
Nearly weld seam carries out welding operation.Pole band top welding seam is in overhead position on spherical tank, and the operation platform at this builds conventional method
It is to be built from bottom to top from inside spherical tank using steel pipe scaffold, re-lays steel bed board or other landing slabs, near upper pole top
An operation platform is built position in portion, meets inner top workmen's job requirements in pole on spherical tank.The building method is for large-scale
Spherical tank, major defect：When spherical tank is relatively large in diameter, built support upper brace needs substantial amounts of steel pipe, building amount it is big and
Tube material utilization rate is low.
The content of the invention
The technical problems to be solved by the invention are for above-mentioned problem, there is provided pole inner top on a kind of spherical tank
Operation is built in the support meanss and building method of platform, simplification, saves frock.
The present invention solves the technical scheme that is used of above-mentioned technical problem：The support of pole inner top platform on a kind of spherical tank
Device, it is characterised in that including support, curved surface backing plate, suspension rod and dowel bar, the support includes several spoke bars and support
Bar, several spoke bars are fixedly connected the other end and circumferentially radiate and set diagonally downward in one end, the other end point of several spoke bars
It is not connected with the top of support bar, the suspension rod top is connected with the tie point of several spoke bars, the level two of the dowel bar
End is connected with the top of support bar and suspension rod respectively, and the top center of the curved surface backing plate is connected with the bottom of support bar, curved surface
The curvature of backing plate is identical with the curvature of pole housing on spherical tank.
By such scheme, the bottom of the suspension rod is conical structure.
By such scheme, the quantity of the spoke bar and support bar is more than three.
The method for carrying out platform building using the support meanss of pole inner top platform on a kind of above-mentioned spherical tank, its feature exists
In comprising the following steps：
A) fittable slackening device, installs several support meanss at same level height in pole housing on spherical tank, will be described
Suspension rod stretches into spherical tank internal cavities through the pore of pole on corresponding spherical tank, and the curved surface backing plate is fixed with the housing of pole on spherical tank
It is connected；
B) hang and connect platform framework, several suspension rods for stretching into are connected with steel pipe, and several steel pipes are crossed to form netted knot in length and breadth
Structure；
C) platform laying, lays plate shaped into an operation platform on the platform framework.
By such scheme, the steel pipe is connected with the suspension rod by fastener.
The beneficial effects of the invention are as follows：There is provided the support meanss and building method of pole inner top platform on a kind of spherical tank,
It is simple with equipment, frock is saved, it is easy to realize, simplifies and builds operation, and the curved surface backing plate of only support bar is direct with spherical tank
Contact, other parts not with spherical tank directly contact, be conducive to avoiding Spherical Tank Shell Plates from being scratched.
Brief description of the drawings
Fig. 1 is the structural representation of the support meanss of one embodiment of the invention.
Fig. 2 is the mounting structure schematic diagram of the support meanss of one embodiment of the invention.
Wherein：1. pole on spherical tank, 2. spoke bar, 3. support bar, 4. curved surface backing plate, 5. suspension rod, 6. dowel bar, 7. platform,
8. pore.
Specific embodiment
To more fully understand the present invention, the invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, on a kind of spherical tank pole inner top platform support meanss, including support, curved surface backing plate 4, hang
Bar 5 and dowel bar 6, support include several spoke bars 2 and support bar 3, and several spoke bars are fixedly connected the other end circumferentially in one end
Radiation is set diagonally downward, and the other end of several spoke bars is connected with the top of support bar respectively, suspension rod top and several spoke bars
Tie point is connected, and the horizontal two ends of dowel bar are connected with the top of support bar and suspension rod respectively, the top center of curved surface backing plate
It is connected with the bottom of support bar, the curvature of curved surface backing plate is identical with the curvature of pole housing on spherical tank.The spoke bar of same support meanss
It it is more than three with the quantity of support bar.
When building, three (or multiple) support bars of the device are fixed on spherical tank on the Shell Plate of pole by curved surface backing plate,
By the curved surface backing plate of the curvature as Spherical Tank Shell Plates, it is allowed to be close to close extremely outside on spherical tank, support pole length is according to spherical tank curvature
Depending on pore position, it is ensured that uniform force；Suspension rod is then stretched through the pore of pole on spherical tank (spherical tank pore quantity is not less than 3)
To inside spherical tank.
It is connected with common scaffolding steel pipe by buckle on suspension rod, is sequentially connected and adds several steel pipes and form netted platform
Framework, lays steel bed board on netted platform framework or other flat boards form an operation platform, and the tapering point of boom foot rises
The effect for preventing fastener pine sliding.
