Abstract
The utility model relates to a round coal yard retaining wall with concrete wall columns and a steel plate wall. The round coal yard retaining wall at least consists of wall supporting columns and a side wall, wherein the wall supporting columns are made of reinforced concrete; the side wall is fixed on the wall supporting columns and is formed by steel plates and steel beams; the wall supporting columns are distributed in a ring shape; the steel beams are circumferentially fixed on all the wall supporting columns, and the circumferential steel beams are connected with the steel plates that are distributed circumferentially; the cross section of each wall supporting column is made into the variable trapezoidal cross section with the upper part being small and the lower part being big; the circumferential steel plates are connected with the circumferential steel beams in an intermittent welding way; and embedded parts are embedded on the wall supporting columns, and the circumferential steel beams are fixedly connected with the wall supporting columns by the embedded parts. The round coal yard retaining wall has the characteristics that the structure is simple, the use and the installation are convenient, the material can be saved, the using cost is reduced, the service life is prolonged, etc.
Description
Technical field
The utility model relates to the wall-retaining structure of a kind of novel steam power station round sealed coal yard, belong 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.
The utility model content
The purpose of the utility model 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 purpose of the utility model is accomplished 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 utility model 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 utility model make detailed introduction: Fig. 1, shown in 2; The buttress 1 that the utility model 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 described buttress 1 of the utility model, described hoop girder steel 3 is fixedly connected on the described buttress 1 through described built-in fitting.
The utility model 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 the said novel barricade of the utility model, 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 3 of the said novel barricade of the utility model and the hoop steel plate 2 intermittently to be welded to connect, accomplish through the field Welding construction.Hoop girder steel 3 is along the quantity of short transverse, and the thickness of the cross-sectional sizes of hoop girder steel 3 and hoop steel plate 2 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 3 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 3 and the built-in fitting.
Claims (3)
1. the circular coal yard barricade of a steel plate wall concrete pilaster; The buttress that it is processed by steel concrete is at least formed with the sidewall wall that is fixed on the said buttress, be made up of steel plate and girder steel; It is characterized in that 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.
