Description
Technical field
The present invention relates to a kind of long-span underground power house furred ceiling arched girder steel-concrete structures.Suitable for underground power house
In the cast-in-place furred ceiling arched girder structure of main building Large span cavern.
Background technique
In main building Large span cavern arrangement in underground power house, generally arranged between ceiling structure and crown palisades
There is ventilating layer, flooring of the ceiling structure as ventilating layer is disposed with the heating and ventilating equipments such as air hose, air-conditioning water pipe thereon.Ceiling structure
Another waterproof interlayer reliable together for functioning as underground power house greatly, can prevent the infiltration of crown palisades from directly instilling
Generator floor in main building influences the normal operation of unit and the working environment of employee.Furthermore ceiling structure is alternatively arranged as
The decorative layer of underground power house plays the role of beautification to separate the rough rock wall surface of crown.
Ceiling structure is made of furred ceiling arched girder and ceiling board, and furred ceiling arched girder undertakes ceiling board self weight as main force structure
And load and load is conducted thereon to end support system.Thus the beam action of furred ceiling arch is huge, at present large span
More commonly used furred ceiling arched girder structure has light section arched girder and formwork erection cast-in-place concrete arched girder structure in lower workshop.Light section arched girder
Have the advantages that quick for installation, easy for construction, but bearing capacity, anticorrosive, fire protecting performance is poor;Formwork erection cast-in-place concrete structure
Have many advantages, such as that bearing capacity is strong, resistance to corrosion is strong, fire protecting performance is good, but furred ceiling trolley formwork erection need to be utilized, assembling reinforcement is simultaneously
Casting concrete, after age needed for concrete reaches design strength can form removal, thus interference of constructing is big, efficiency
It is low, long in time limit.
Summary of the invention
The technical problem to be solved by the present invention is in view of the above problems, it is strong, anticorrosive to provide a kind of bearing capacity
The long-span underground power house furred ceiling arched girder steel-concrete structure that ability is strong, fire protecting performance is good, quick for installation, easy for construction.
The technical scheme adopted by the invention is that: a kind of long-span underground power house furred ceiling arched girder steel-concrete structure, it is special
Sign is: having steel arch beam, the elongated cladding sheet metal in the bottom and two sides of the steel arch beam forms concrete pouring groove, and concrete pours
Build filling concrete and vibration compacting in slot.
The steel arch beam has four along the elongated arrangement of steel arch beam and is located at the logical of four Angle Positions of steel arch beam section
Long angle steel is connected between elongated angle steel through several limit stirrups.
Several internal reinforcement angle steel are equipped in the steel arch beam, angle steel is reinforced by the equal leg angle of two arranged crosswises in inside
Composition, the inside are reinforced angle steel and are fixedly connected respectively with four elongated angle steel.
The two sides of the steel arch beam are equipped with several web members, and web member is along the elongated direction herringbone arrangement of steel arch beam, web member both ends
It is separately connected the ipsilateral two elongated angle steel up and down of steel arch beam.
The both ends of the steel arch beam are fixed with end steel plate.
The limit stirrup is 150mm along the arrangement spacing of the elongated angle steel length direction.
The internal reinforcement angle steel is 1500mm along the arrangement spacing of the elongated angle steel length direction.
The beneficial effects of the present invention are: the present invention has drawn the advantage of steel construction and concrete structure respectively, not only have
The advantages that bearing capacity is strong, resistance to corrosion is strong, fire protecting performance is good, and quick for installation, easy for construction, mounted steel construction
Template when as pouring concrete is not necessarily to assembling reinforcement, thus constructs and interfere small, high-efficient, short time limit.
Detailed description of the invention
Fig. 1 is the overall structure profilograph of embodiment.
Fig. 2 is the cross-sectional view of embodiment.
Specific embodiment
As shown in Figure 1 and Figure 2, the present embodiment is a kind of long-span underground power house furred ceiling arched girder steel-concrete structure, is had
Steel arch beam and concrete structure.
Steel arch beam has four elongated angle steel 1 along the elongated arrangement of steel arch beam in the present embodiment, and four elongated angle steel 1 are distinguished
It is arranged at four angles of steel arch beam section, is connected between elongated angle steel 1 through several limit stirrups 2.Stirrup 2 is limited along elongated angle
1 length direction of steel arranges that spacing is 150mm, which is made of four reinforcing bars for being arranged in arched girder section surrounding, limits
By being welded to connect between stirrup 2 and elongated angle steel 1, using being fully welded, weld bead height cannot be less than the minimum thickness of connecting elements.
Several internal reinforcement angle steel 4 are equipped in steel arch beam, angle steel 4 is reinforced by the equal leg angle group of two arranged crosswises in inside
At the both ends of every equal leg angle are separately connected the elongated angle steel 1 of a pair of pairs of angular dependence.Reinforce angle steel 4 along elongated angle in inside
Steel length direction arranges that spacing is 1500mm, and inside is reinforced adopting between angle steel 4 and with elongated angle steel 1 by being welded to connect
With being fully welded, weld bead height cannot be less than the minimum thickness of connecting elements.
The two sides of steel arch beam are equipped with several web members 3 in the present embodiment, and web member 3 is along the elongated direction herringbone arrangement of steel arch beam.
By being welded with reinforcement welding connection between web member 3 and ipsilateral two elongated angle steel 1 up and down, web member 3 and it is welded with reinforcing bar, is welded with steel
Muscle is all made of with elongated angle steel 1 and is fully welded, and weld bead height cannot be less than the minimum thickness of connecting elements.
In the elongated cladding sheet metal 5 in the bottom of steel arch beam and two sides in this example, end steel plate 6 is fixed at the both ends of steel arch beam,
Sheet metal 5 and end steel plate 6 form the concrete pouring groove along the elongated arrangement of steel arch beam.By being welded to connect between sheet metal 5,
Using being fully welded, by being welded to connect between sheet metal 5 and elongated angle steel 1, is welded using interval, the long 50mm of weld seam, is spaced 150mm,
Weld bead height cannot be less than the minimum thickness of connecting elements.End steel plate 6 is located at steel arch beam both ends, and be located at steel arch beam four
The elongated angle steel end at angle is welded, and using being fully welded, weld bead height cannot be less than the minimum thickness of connecting elements.
The concrete pouring groove fill concrete 7 formed in the present embodiment in sheet metal 5 and end steel plate 6, and to ask for help
Work vibration compacting.
All steel members and its weld seam exposed parts should all first apply two degree of red lead phenolic aldehyde anti-corrosive primer in the present embodiment, then cover
The two degree of progress preservative treatments of grey phenolic aldehyde rust-proof top-coat.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
Those of ordinary skill, within the scope of the invention, variation, addition or the replacement made all should belong to protection scope of the present invention.
