Abstract

The invention discloses a supporting steel frame of a high altitude large-span cantilever structure mold frame. The supporting steel frame comprises a floor slab, a supporting frame and a cantilever beam, wherein the supporting frame is of triangular shape; the lower end of the triangular supporting frame is mounted on an embedded iron piece on a lower floor slab; the upper end of the triangular supporting frame is provided with the cantilever beam; and one end of the cantilever beam penetrates in an anchoring ring mounted on an upper floor slab and is wedged through a wooden wedge. The supporting steel frame of the high altitude large-span cantilever structure mold frame, disclosed by the invention, has the advantages of reasonable stress, high rigidity, strong bearing force at the cantilever end, large cantilever span, strong bearing force, large rigidity of the frame body and capability of effectively ensuring the integral stability and construction safety of the large-span cantilever structure mold frame. The steel frame can be integrally spliced on the site in advance and has the advantages of lightweight frame body, convenience for mounting and detaching and labor and time conservation. The supporting steel frame can be recycled for multiple times, obtains better economic benefits and is worthy of being generalized.

Description

The supporting steel frame of high-altitude long-span cantilevered structure mould bases
Technical field
The invention belongs to the supporting steel frame of encorbelmenting and relate to the realm of building construction, relate in particular to a kind of supporting steel frame that is used for high-altitude long-span cantilevered structure mould bases.。
Background technology
Along with the continuous development of building technology, the architect more and more pays attention to the appearance and modeling of building, adopts the cantilevered structure of high-altitude, large span, overlength usually, realizes the modeling effect that building is grand, serious.Adopt traditional steel I-beam to encorbelment, the span that girder steel is chosen building structure is little, encorbelments a little less than the end bearing capacity, can't satisfy the requirement of carrying large span cantilevered structure mould bases; And adopt the console mode scaffold to support, and need set up the tall and big support body of complex structure, take a lot of work, take material, time-consuming, both dangerous more uneconomical.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of supporting steel frame of high-altitude long-span cantilevered structure mould bases is provided, solved traditional steel I-beam of encorbelmenting and chosen little, the hypodynamic shortcoming of end carrying of encorbelmenting of span.
The present invention realizes through following technical scheme:
A kind of supporting steel frame of high-altitude long-span cantilevered structure mould bases; Comprise floor, bracing frame and the beam of encorbelmenting; Support frame as described above is a triangle, and the lower end of triangle support frame is installed in down the embedded iron parts on the floor, and the upper end of triangle support frame is provided with the beam of encorbelmenting; The end of beam of encorbelmenting passes in the anchor ring that is installed on the floor, and through the timber wedge wedging.
Said triangle support frame is made up of hound, horizontal web member and diagonal brace web member; Said hound is two; Their in a certain angle and lower ends all are packed in the embedded iron parts portion on the floor; Said horizontal web member level is installed between two hounds, and said diagonal brace web member is installed between per two horizontal web members and is in a certain angle with horizontal web member.
On horizontal web member, short tube is installed.
On last floor, be provided with blind hole, the beam of encorbelmenting is provided with and this corresponding through hole in blind hole position, is provided with pin in through hole and the blind hole.
Advantage of the present invention is: supporting steel frame structure stress of the present invention is reasonable, rigidity is high, the end bearing capacity of encorbelmenting is strong, and the span of encorbelmenting is big, and bearing capacity is strong, and support body rigidity is big, can effectively guarantee the monolithic stability and the construction safety of large span cantilevered structure mould bases.Steelframe can be put in order the Pin assembly unit at the scene in advance, and support body is light and handy, and assembling and disassembling is convenient, saving of work and time.Supporting steel frame can have enough to meet the need repeatedly and use, and has favorable economic benefit, is worthy to be popularized.
Description of drawings
Figure is a structural representation of the present invention.
The specific embodiment
Embodiment: the supporting steel frame of high-altitude long-span cantilevered structure mould bases as shown in the figure; Comprise floor, bracing frame and the beam of encorbelmenting; Support frame as described above 14 is a triangle; Triangle support frame 14 is made up of hound 8, horizontal web member 9 and diagonal brace web member 10, and said hound 8 is two, and their in a certain angle and lower ends all are packed in down 12 ones of embedded iron parts on the floor 13; Said horizontal web member 9 levels are installed between two hounds 8, and said diagonal brace web member 10 is installed between per two horizontal web members 9 and is in a certain angle with horizontal web member 9.On horizontal web member 9, short tube 11 is installed.The upper end of triangle support frame is provided with the beam 4 of encorbelmenting, and an end of the beam 4 of encorbelmenting passes in the anchor ring 2 that is installed on the floor 1, and through timber wedge 3 wedgings.On last floor 1, be provided with blind hole 5, the beam 4 of encorbelmenting is provided with and the corresponding through hole 6 in this blind hole 5 positions, is provided with antiskid in through hole 6 and the blind hole 5 and moves reinforcing bar pin 7.
The bracing frame 14 of above-mentioned high-altitude long-span cantilevered structure mould bases setting-out making assembly unit at the construction field (site) during construction, its all rod nodes all adopt welding, constitute whole Pin triangular support steelframe with beam 4 welding of encorbelmenting again.Triangular supporting steel used crane hoisting, cantilevered beam 4 passes through the embedded anchor ring 2, the frame body position adjustment is completed, with a wedge 3 wedged tight, triangular support frame 14 at the bottom with embedded iron 12 welded .Insert antiskid and move reinforcing bar pin 7, the pinning level beam of encorbelmenting.On horizontal web member 9, respectively weld a short steel pipes 11, the elongated steel pipe of fixing vertically connection.
Behind each Pin triangular support steelframe installation in position, each Pin supporting steel frame is connected into integral body with vertical elongated steel pipe.On supporting steel frame, completely spread wooden springboard, set up the falsework of cantilevered structure, the vertical rod of mould bases is set up directly over steelframe.
When floor height during, increase together horizontal web member 9 with diagonal brace web member 10 greater than 4.5m.
