Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Specific embodiment 1:
With reference to Fig. 1, Fig. 2, the present embodiment comprises some pillars 1 and some frame beams 2, is enclosed by described pillar 1Become cuboid, on differing heights, be fixedly connected with and form multilayer cuboid frame structure by described frame beam 2 and pillar 1; ?The bottom surface of every layer of cuboid frame structure arranges some longerons 4 and some crossbeams 5, to strengthen each layer of cuboid frameworkStiffness; Several concrete diagonal braces 3 are set on one deck cuboid framework, are arranged on the same layer of cuboid frameworkUpper, do not have the setting of longeron direction, form shearing resistance and anti-seismic structure; Two pillars 1 of horizontally set of cuboid frame structure,Form uni-frame construction; Two bases that coal pulverizer are set across this of cuboid framework, form the list that is applicable to low intensity areaFrame-type side coal bunker structure.
In the present embodiment:
In same cross section, between adjacent four pillars 1, be fixedly connected with by four frame beams 2, form horizontal rectangular frameworkStructure; Two concrete diagonal braces 3 are set, described concrete diagonal brace 3 on the facade in same level rectangular frame structureBottom be fixedly connected with the bottom comer of this facade, the middle part of frame beam 2 on top and this facade or crossbeam 5 is hinged or solidFixed connection, form isosceles triangular structure.
The base angle of the equilateral triangle structure that described concrete diagonal brace 3 forms is 44 °.
Frame beam 2 is perpendicular to the pillar 1 supporting, and frame beam 2 is rigidly connected with pillar 1, longeron 4 be longitudinal secondary beam, andThe frame beam 2 supporting is vertical, and longeron 4 is articulated and connected with frame beam 2.
Concrete diagonal brace 3 is hinged with pillar, to increase horizontal rigidity.
In the present embodiment, two organ timbering 1 axis are parallel, and pillar 1 is arranged between two parties along axis. Two across a placement be millCoal machine basis.
Frame beam 2 is perpendicular to the pillar 1 supporting, and frame beam 2 is rigidly connected with pillar 1, longeron 4 be longitudinal secondary beam, andThe frame beam 2 supporting is vertical, and longeron 4 is articulated and connected with frame beam 2. The perpendicular wall of concrete is perpendicular to ground. Concrete diagonal brace 3Into about 44 ° of angles, concrete diagonal brace 3 is articulated and connected with pillar 1 with ground.
The present embodiment is different from frame-generic structure part and is laterally only there are two pillars 1, therefore be uni-frame construction.Concrete diagonal brace 3 in this programme is hinged with pillar, has increased horizontal rigidity, provides favorable factor to structural seismic.
Except basic structure, this programme can also be by reducing the pattern of the number of plies and floor height, change diagonal brace, or at layerBetween laterally increase the modes such as diagonal brace and carry out preferred arrangements, further improve the anti-seismic performance of structure.
The operation principle of the present embodiment is as follows:
The mode that the utility model takes single frame to arrange, is oppositely arranged by arranging two in the wide rectangular frame structure of solidConcrete diagonal brace 3 form delta-shaped region, can greatly increase the stability of three-dimensional wide rectangular frame structure. Three-dimensional narrowRectangular frame structure connects two horizontal rectangular frame structures by longeron 4, and the narrow rectangular frame structure of solid is played to reinforcingEffect, has reduced the consumption of concrete and reinforcing bar and has saved financial cost, and " thermal power plant civil engineering structure is established to meet ChinaMeter technical regulation " about the requirement of single frame suitable with prior art stability.
And the construction of frame structure is simpler, easy to operate than the construction of shear wall, template colligation convenient and template weightMultiple utilization rate is high, and the construction of frame structure also more easily ensures construction quality, greatly shortens the construction period.
Taking certain power plant's uni-frame construction and Frame _ Shear Wall Structure as example, common practices and the utility model way are enteredThe contrast of row cost, the results are shown in Table 2.3-1 and table 2.3-2. Total cost contrasts in Table 2.3-3.
The contrast of table 2.3-1 concrete cost
The contrast of table 2.3-2 reinforcing bar cost
The contrast of table 2.3-3 total cost
The present embodiment can also be by reducing the profile of the number of plies and floor height, change diagonal brace or the angle with ground, orLaterally increase the modes such as diagonal brace at interlayer and arrange, further improve the anti-seismic performance of structure.
Specific embodiment 2:
The feature of the present embodiment 2 is: described concrete diagonal brace 3 is located at the side of cuboid framework different layers, forms toolThere is the single frame posture side coal bunker structure of shearing resistance and anti-seismic structure. All the other are with specific embodiment 1.
The above, be only preferably specific embodiment of the utility model, but not office of protection domain of the present utility modelBe limited to this, any be familiar with those skilled in the art the utility model disclose scope in, according to the utility modelTechnical scheme and design be equal to replace or change, all belong to protection domain of the present utility model.
