Abstract
The invention discloses a round coal yard barricade of a concrete pilaster of a steel plate wall. The round coal yard barricade at least consists of reinforced concrete support pilasters and a side wall of steel plates and steel beams fixed on the support pilaster, wherein the support pilasters are uniformly annularly distributed; the steel beams are annularly fixed on all support pilaster, and the annularly arranged steel beams are connected with steel plates which are annularly arranged; the section of the support pilaster is made into a variable-section trapezoidal section with a small top and a big bottom; the annularly arranged steel plates are connected to the annularly arranged steel beams by intermittent welding; an embedded parts are embedded on the support pilasters; and the annularly arranged steel beams are fixedly connected on the support pilasters through the embedded part. The round coal yard barricade disclosed by the invention has a simple structure, is convenient to use and mount, saves material, reduces the use cost and prolongs the service life and the like.
Description
Technical field
What the present invention relates to is the wall-retaining structure of a kind of novel steam power station round sealed coal yard, belongs to power plant civil engineering structure technical field.
Background technology
Traditional circular coal yard wall-retaining structure has following several kinds:
The separate type barricade of 1 reinforced concrete soil zone pilaster and temperature joint;
2 steel concrete do not have pilaster integral seamless ring-plate barricade;
3 reinforced concrete soil zone pilaster integral seamless formula barricades;
4 reinforced concrete soil zone pilaster and ring beam integral seamless formula barricade;
Tradition separate type barricade calculates simple, but waste of material.Traditional integral barricade calculation of complex, especially temperature action is complicated, is difficult to accurate consideration; The Crack Control that the barricade arrangement of reinforcement is caused by temperature action, reinforcement stresses are 160N/mm
2About, not only actual reinforcing bar consumption is huge, and has potential security risk.
Summary of the invention
The object of the invention mainly is to implement the target of national energy-saving and emission-reduction, overcomes the deficiency that above-mentioned prior art exists, and a kind of easy construction is provided, the circular coal yard barricade of the steel plate wall concrete pilaster of material economy.
The objective of the invention is to accomplish through following technical scheme; The buttress that it is processed by steel concrete at least be fixed on the sidewall wall that steel plate on the said buttress adds girder steel and form; Described buttress is uniformly distributed with ringwise; Described girder steel hoop is fixed on all buttresses, and on described hoop girder steel, is connected with the steel plate that hoop is arranged.
The cross section of said buttress is made into up-small and down-big variable cross-section trapezoidal cross-section; Described hoop steel plate is connected on the described hoop girder steel through discontinuous welding in succession.
Be embedded with built-in fitting on the described buttress, described hoop girder steel is fixedly connected on the described buttress through described built-in fitting.
The present invention is owing to brought into play the tensile strength of concrete compressive strength and steel simultaneously, and comprehensive cost practices thrift about 30% than traditional form; Construction period practiced thrift 1 month than traditional structure; Have simple in structure, easy to install and use, can economical with materials, reduce use cost, increase characteristics such as application life.

The specific embodiment
To combine below accompanying drawing to the present invention make detailed introduction: Fig. 1, shown in 2; The buttress 1 that the present invention is mainly processed by steel concrete be fixed on the sidewall wall that steel plate 2 on the said buttress 1 adds girder steel 3 and form; Described buttress 1 is uniformly distributed with ringwise; Described girder steel 3 hoops are fixed on all buttresses 1, and on described hoop girder steel 3, are connected with the steel plate 2 that hoop is arranged.
The cross section of buttress shown in the figure 1 is made into up-small and down-big variable cross-section trapezoidal cross-section; Described hoop steel plate 2 is connected on the described hoop girder steel 3 through discontinuous welding in succession.
Be embedded with built-in fitting on the buttress 1 of the present invention, described hoop girder steel 3 is fixedly connected on the described buttress 1 through described built-in fitting.
The present invention is because the barricade sidewall is stressed with stretch bending control, and the intensity of steel structure material is high, and temperature action is insensitive, does not have the crack problem of reinforced concrete structure simultaneously again, so can economical with materials.
The quantity of the buttress 1 of novel barricade according to the invention, preferably 36, total symmetry like this, concrete certainly quantity should be calculated definite by loading conditions such as the diameter of barricade and coal piling height.
The buttress 1 of said novel barricade adopts monolithic reinforced concrete structure, by the building-site casting and constructing.The pilaster of steel concrete can provide barricade required rigidity.According to the loading characteristic of buttress, be preferably made top little below big variable cross-section trapezoidal cross-section, like this can economical with materials.The concrete cross-sectional sizes of buttress is calculated by loading conditions such as the diameter of barricade and coal piling height and to be confirmed.
Adopt between the hoop girder steel 2 of novel barricade according to the invention and the hoop steel plate 3 intermittently to be welded to connect, accomplish through the field Welding construction.Hoop girder steel 2 is along the quantity of short transverse, and the thickness of the cross-sectional sizes of hoop girder steel 2 and hoop steel plate 3 is calculated by loading conditions such as the diameter of barricade and coal piling height and to confirm.
Being connected between the hoop girder steel 2 of said novel barricade and the buttress 1 preferably is employed in the buttress 1 and buries built-in fitting underground, is connected by field Welding between hoop girder steel 2 and the built-in fitting.
