Abstract
The invention discloses a thermal power plant boiler pedestal and foundation connection structure and method thereof. The structure thereof comprises: a steel dowel (2) is arranged in a foundation (5) on the top of which a steel embedded part (4) is arranged; the steel embedded part (4) is welded with a boiler steel column (1); and the foundation steel dowel (2) is welded with the boiler steel column (1). A steel pedestal bottom slab (3) is arranged on the steel embedded part (4) which is welded with the steel pedestal bottom slab (3); and the boiler steel column (1) is welded with the steel pedestal bottom slab (3). The method thereof comprises: the steel dowel (2) is firstly pre-arranged at a foundation location, and then the lower part of the foundation (5) is cast; the steel embedded part (4) is pre-embedded in the foundation (5); the boiler steel column (1) is welded with the foundation steel embedded part (4); later the foundation steel dowel (2) is welded on the steel column (1); finally, the short column of the concrete on the upper part of the foundation (5) is cast. The invention causes the boiler steel column pedestal to be rigidly linked with the foundation, transmits the load on the upper part structure of the boiler, and ensures the safety of the plant buildings and the functional needs thereof.
Description
Technical field
The present invention relates to a kind of thermal power plant boiler steel column foot and foundation connection structure and method thereof.
Technical background
According to the needs of thermal technology's specialty, the boiler of steam power plant generally all is 40 meters high steel columns, and because the expansion of steam, the internal force that passes to suspension column is generally all very big.For the internal force of suspension column can be passed on the basis, then take rigid connection between steel column foot and the basis.It generally is to reserve bolt in the basis that steel column foot is connected with the basis, is connected with the steel column base plate again, because boiler steel suspension column internal force is very big, connects with bolt herein and can not satisfy requirement for bearing capacity, brings potential safety hazard to total.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of thermal power plant boiler pedestal and foundation connection structure and method thereof are provided, boiler steel column foot and basis are formed rigid connection, to satisfy the requirement of bearing capacity.
In order to solve the problems of the technologies described above, the present invention has taked following technical scheme:
In the basis, reserve joint bar, basic top pre-buried steel embedded part, with boiler steel column and the welding earlier of basic embedded part, basic joint bar is welded on the steel column, waters the concrete short column again, and forming boiler steel column foot and basis is rigid connection.Water short column again by reinforcing bar and steel column postwelding on steel column pin and welding of basic top embedded part and the basis, make steel column foot and basis be connected to form a kind of rigid connection, the internal force (axle power, moment of flexure, shearing) of superstructure is passed to the basis, guarantee the safety of total.Like this, because basis and boiler steel column are rigid connections, then boiler steel column foot internal force (axle power, moment of flexure, shearing) directly passes on the basis.
Owing to adopted technique scheme, the present invention that the thermal power plant boiler steel column is connected with basic rigidity, guaranteed that the safety of total and factory building function need.

Fig. 2 is a basic sectional drawing of the present invention;
Fig. 3 is a boiler steel column foot sectional drawing of the present invention.
The specific embodiment
Embodiments of the invention: structure of the present invention is as follows:
Embodiment one, it comprises boiler steel column 1, basic joint bar 2, steel column basis 5, in basis 5 joint bar 2 is arranged, and on the top, basis steel embedded part 4 is arranged, steel embedded part 4 and 1 welding of boiler steel column, basic joint bar 2 and 1 welding of boiler steel column.
Embodiment two, being welded to connect for the ease of boiler steel column 1 and steel embedded part 4 with stressed better, on the basis of said structure, increase bottom plate of steel column foot 31 time at the boiler steel column, this bottom plate of steel column foot 3 welds with boiler steel column 1 earlier, again with bottom plate of steel column foot 3 and in 4 welding of steel embedded part.
Embodiment three, for the stressing conditions of improving boiler steel column 1 with gain in strength, on the basis of the foregoing description one or embodiment two structures, increase by 4 steel column pin boots plates 6 around boiler steel column 1, steel column pin boots plate 6 is welded to connect with boiler steel column 1, steel embedded part 4 or bottom plate of steel column foot 3.
Method of the present invention is as follows: preset cast basis, joint bar 2 back 5 in base position earlier, pre-buried steel embedded part 4 in basis 5 with boiler steel column 1 and basic steel embedded part 4 welding, is welded on basic joint bar 2 on the steel column 1 again, pours into a mould the concrete short column on basic 2 tops at last.The C30 concrete is adopted in the cast on basis 1.In the situation of structure such as embodiment two, should earlier bottom plate of steel column foot 3 and boiler steel column 1 be welded, again with bottom plate of steel column foot 3 and in 4 welding of steel embedded part; In the situation of structure such as embodiment three, should earlier bottom plate of steel column foot 3 and/or steel column pin boots plate 6 be welded with boiler steel column 1, again with bottom plate of steel column foot 3 and in 4 welding of steel embedded part.
Claims (4)
- [claim 1] a kind of thermal power plant boiler pedestal and foundation connection structure, it is characterized in that: in basis (5), joint bar (2) is arranged, on the top, basis steel embedded part (4) is arranged, steel embedded part (4) and boiler steel column (1) welding, basic joint bar (2) and boiler steel column (1) welding.
