Abstract
The invention provides a supporting device and a construction method for a top platform in an upper pole of a spherical tank. The supporting device comprises a support, a curved surface cushion plate, a hanging rod and connection rib rods. The support comprises a plurality of spoke rods and supporting rods. One ends of the spoke rods are fixedly connected. The other ends of the spoke rods are obliquely arranged downwards in a circumferential irradiation mode. The other ends of the spoke rods are connected with the top ends of the supporting rods. The top end of the hanging rod is connected with the connection point of the spoke rods. The two horizontal ends of each connection rib rod are connected with the top of the corresponding supporting rod and the hanging rod respectively. The top center of the curved surface cushion plate is connected with the bottom ends of the supporting rods. The curvature of the curved surface cushion plate is the same as that of a shell of the upper pole of the spherical tank. The supporting device and the construction method are simple in structure and capable of improving the construction efficiency.
Description
Technical field
The invention belongs to the technical field of spherical tank assembling, particularly relate to bracing or strutting arrangement and the building method of inner top platform in pole on a kind of spherical tank.
Background technology
Along with petrochemical industry spherical storage tank volume constantly maximizes, 3000m
3above spherical tank application is more and more universal.Spherical tank is formed by the welding of polylith spherical shell lobe, and the site operation groundwork amount of large-size spherical tank is assembling and welding, and sphere welding workload major part completes at the scene.Therefore, need to build construction operation platform in the inside and outside portion of spherical tank, make operating personnel can carry out welding operation near weld seam.On spherical tank, pole band top welding seam is in overhead position, conventional method built by the operation platform at this place is adopt steel pipe scaffold to build from spherical tank inside from bottom to top, re-lay steel bed board or other landing slab, near on pole tip position build an operation platform, meet pole inner top constructor job requirements on spherical tank.This building method is for large-size spherical tank, and major defect: when spherical tank diameter is larger, built supports upper brace needs a large amount of steel pipes, and building amount is large and tube material utilization rate is low.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned Problems existing, provides bracing or strutting arrangement and the building method of inner top platform in pole on a kind of spherical tank, simplifies and builds operation, saves frock.
The present invention solves the problems of the technologies described above adopted technical scheme: the bracing or strutting arrangement of pole inner top platform on a kind of spherical tank, it is characterized in that, comprise support, curved surface backing plate, suspension rod and dowel bar, described support comprises several spoke bar and support bar, described several spoke bar be one end be fixedly connected with the other end circumferentially radiation be tilted to lower setting, the other end of several spoke bar is connected with the top of support bar respectively, described suspension rod top is connected with the tie point of several spoke bar, the horizontal two ends of described dowel bar are connected with the top of support bar and suspension rod respectively, the described top center of curved surface backing plate 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.
By such scheme, the bottom of described suspension rod is conical structure.
By such scheme, the quantity of described spoke bar and support bar is more than three.
Adopt the bracing or strutting arrangement of pole inner top platform on above-mentioned a kind of spherical tank to carry out the method for platform building, it is characterized in that, comprise the steps:
A) fittable slackening device, on spherical tank, on the housing of pole, same level At The Height installs several bracing or strutting arrangement, and described suspension rod is stretched into spherical tank internal cavities through the pore of pole on corresponding spherical tank, and on described curved surface backing plate and spherical tank, the housing of pole is fixedly linked;
B) hang and connect platform framework, several suspension rod stretched into all is connected with steel pipe, and several steel pipe intersects in length and breadth and forms net structure;
C) platform is laid, and described platform framework is laid plate shaped one-tenth operation platform.
By such scheme, described steel pipe is connected by fastener with described suspension rod.
The invention has the beneficial effects as follows: the bracing or strutting arrangement and the building method that provide inner top platform in pole on a kind of spherical tank, there is equipment simple, save frock, realize easily, simplify and build operation, only the curved surface backing plate of support bar directly contacts with spherical tank, and other parts all directly do not contact with spherical tank, is conducive to avoiding Spherical Tank Shell Plates to be scratched.

Fig. 2 is the mounting structure schematic diagram of the bracing or strutting arrangement 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.
Detailed description of the invention
For understanding the present invention better, below in conjunction with drawings and Examples, the invention will be further described.
As Fig. 1, shown in Fig. 2, the bracing or strutting arrangement of pole inner top platform on a kind of spherical tank, comprise support, curved surface backing plate 4, suspension rod 5 and dowel bar 6, support comprises several spoke bar 2 and support bar 3, several spoke bar be one end be fixedly connected with the other end circumferentially radiation be tilted to lower setting, the other end of several spoke bar is connected with the top of support bar respectively, suspension rod top is connected with the tie point of several spoke bar, 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 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 bracing or strutting arrangement and the quantity of support bar are more than three.
When building, three (or multiple) support bars of this device to be fixed on spherical tank on the Shell Plate of pole by curved surface backing plate, by the curved surface backing plate of curvature the same as Spherical Tank Shell Plates, make it to be close on conjunction spherical tank extremely outside, support bar length is determined according to spherical tank curvature and pore position, ensures uniform force; Suspension rod then reaches spherical tank inside through the pore (spherical tank pore quantity is not less than 3) of pole on spherical tank.
Suspension rod is connected with common scaffolding steel pipe by buckle, connect successively and add several steel pipe and form netted platform framework, netted platform framework is laid steel bed board or other dull and stereotyped formation operation platform, and the tapering point of boom foot plays a part to prevent fastener pine sliding.
