Description
Technical field
The present invention relates to a kind of basement support constructions with armpit angle, are suitable for building field.
Background technique
In recent years with the rapid development of urban engineering construction, a large amount of deep basement engineering has been emerged in large numbers.Basement supporting knot
Structure must also meet deformation requirements in addition to meeting self-strength requirement, so that the design and construction of basement engineering be made to carry out by force
Degree and deformation double control.For irregular basement, safety precaution is very difficult, and using inner support, not only cost is high merely,
Construction speed is also undesirable.It can be supported in conjunction with the good load-carrying properties of ring beam, using waist rail as the transmitting structure of support
Part.But bracing members and waist rail are often oblique in irregular basement, when bracing members and waist rail oblique, when supporting stress
Horizontal component can be being generated along waist rail direction, failure by shear is easy to appear between waist rail and enclosure wall or fender post.
Summary of the invention
The present invention is to overcome prior art problem, provides a kind of basement support construction with armpit angle, keeps basement safe
Construction.
For this purpose, the basement support construction provided by the invention with armpit angle, waist rail, first of waist rail is arranged in enclosure wall inside
Using armored concrete, first waist rail is arranged position following 50cm~80cm at the top of enclosure wall, second waist rail or with
Lower waist rail uses steel member.First of waist rail can suitably be reinforced as interim vehicle of constructing using armored concrete by regional area
Trade facilitates constructing operation.It is to accelerate construction progress and saving engineering that second waist rail or following waist rail, which use steel member,
Cost.Ring beam is set on the inside of waist rail, and ring beam height is 500mm~700mm, and ring beam width is 250mm~300mm, in basement
Portion is very big by moment of flexure and shearing, and using truss to support in the middle part of basement, truss can also reduce the support span of waist rail to support
And alleviate the stress of waist rail.
The horizontally-supported clear distance between underground structure floor and basement bottom board is 600~800mm, the cloth of the road Xia support
It sets under the conditions of not influencing main structure construction and earth excavation, should reduce as far as possible to reach best stressed effect, the road Xia branch
It supports with a distance from basement bottom board as 300~400mm.When the thickness of sole plate is greater than 900mm, the support of the road Xia is retained in ground
In the bottom plate of lower room.
Reinforced concrete waist rail is connect with enclosure wall one-piece casting, can be multiplied by amplitude modulation reduction coefficient to support moment is calculated
0.85~0.95, but mid span moment is increase accordingly to 1.05~1.15.The cross-sectional width of reinforced concrete waist rail is greater than its water
1/10 to effective span is put down, cross-sectional width should be greater than depth of section, and depth of section is greater than the depth of section of support.Reinforcing bar
The longitudinal reinforcement diameter of concrete breast beam be greater than or be equal to 20mm, be greater than along the maximum spacing of section surrounding longitudinal reinforcement or
Equal to 300mm.Stirrup diameter is greater than or is equal to 8mm, and spacing is greater than or is equal to 250mm.
It is greater than the basement of 40m for span, truss support will consider the influence of temperature change, rule of thumb provide with actual measurement
Material, truss support will increase by 8%~10% internal force load.
Steel pipe, fashioned iron, I-steel or channel steel and combinations thereof component can be used in bracing members.In bracing members, the node of steel waist rail
Or angular position, the edge of a wing of Steel section member and ventral margin are welded with steel stiffener, the thickness of steel stiffener is greater than or equal to 10mm, weldering
Seam height is greater than or equal to 6mm.
When there is external corner in irregular basement, it may occur that stress concentration phenomenon, this position, which is easy to appear, to be collapsed, especially
That first of horizontally-supported stress can be very big, first of horizontally-supported basement external corner part add concrete cast-in-place slab into
Row is reinforced, and concrete cast-in-place slab controls position deformation with a thickness of 10mm~15mm.Basement internal corner part uses bracing members.
Second is horizontally-supported and other support basement external corner parts or internal corner part to be all made of bracing members.To the hole other places at external corner
Base carries out grouting and reinforcing, improves and cheats outer soil strength, to reduce the lateral pressure of enclosure wall.
When bracing members and waist rail oblique, horizontal component can generated along waist rail direction when stress by supporting, to transmit this water
Shear transfer device need to be arranged in flat power between waist rail and enclosure wall or fender post.
Enclosure wall is used for building enclosure, for enclosure wall with a thickness of 300mm~350mm, enclosure wall inner surface is embedded pre-
Iron is buried, it is 500mm~600mm that embedded iron, which buries spacing, and embedded iron is with a thickness of 4mm~6mm, embedded iron width and length
200mm~350mm, pre-buried iron surface welding steel shear block, and steel shears block with a thickness of 50mm~60mm, and steel shears block width and length
Degree is 150mm~200mm, and in order to reduce cost, steel shears block and uses the hollow bloom of lattice, between enclosure wall and steel waist rail
Clog pea gravel concreten.Steel waist rail uses fashioned iron, and cross-sectional width is 300mm~500mm, and steel waist rail inner surface welds steel pad
Block, steel cushion block are made into triangle, and steel cushion block surface slope is consistent with the oblique gradient of steel waist rail, and steel cushion block horizontal plane and bracing members hang down
Directly.
Fender post is used for building enclosure, fender post diameter is 600mm~800mm, and the rebar surface of fender post welds
Rebar connector, rebar connector are formed by bar reinforcement annular solder, and bar reinforcement diameter is 28mm or 32mm, rebar connector
