Abstract
The invention discloses a kind of radial 0# blocks carrier structure of multilayer groined type.Its structure is：In oval petal thin-walled hollow pier shaft（13）Bracket embedded section on the different pre-buried shelf brackets of elevation location（14）With lower bracket steel plate box（15）, it connects shelf bracket, and planar graph is radial into groined type, and bridging is connected between each shelf bracket（9）, Bailey beam is installed on each shelf bracket（11）And I-steel（12）.The present invention solves the problem of 0# sections of box beam four sides great cantilevers on pier shaft, and ensure that the globality of pier shaft concrete to the full extent；Upper bracket is by the way of bracket embedded section shaped steel pin joint on connecting cleat and pier shaft, lower bracket is by the way of cutting bar-shaped wing plate is sealed up and steel plate box is inserted after plate reinforcement and stoppers steel plate, the quality and safety risk that conventional bracket is largely welded in the air is avoided, bracket installation rate is fast, and installation operation is simple and easy to control.
Description
Technical field
The present invention relates to a kind of 0# blocks carrier structure.
Background technology
In 0# block non-floor-bracket Construction Schemes, it will usually select carrier structure, traditional 0# block carrier structures
Design above and below pier shaft bracket junction pre-embedded steel slab, up and down bracket weld in the air, and at upper bracket to draw, planar graph into
Single-layer orthogonal shape, its presence is larger to the destruction of pier shaft single elevation location section concrete globality, be not suitable for abnormity cuts
The characteristics of face pier and four sides great cantilever 0# blocks, have a strong impact on pier shaft concrete quality and outward appearance, and installation period length, quality and peace
Full blast danger is high.
The content of the invention
The technical problem to be solved in the present invention is：There is provided a kind of multilayer groined type radial 0# blocks carrier structure, to solve
The problems of 0# sections of box beam four sides great cantilevers on pier shaft, and the globality of pier shaft concrete is ensure that to the full extent；Upper ox
Leg is by the way of bracket embedded section shaped steel pin joint on connecting cleat and pier shaft, and lower bracket is sealed up plate using cutting bar-shaped wing plate and mended
Steel plate box is inserted after strong and M50 support grouting material pour into the mode of filling, has avoided the quality that conventional bracket is largely welded in the air
With security risk, soon, installation operation is simple and easy to control for bracket installation rate.
The technical scheme is that：The ox on the pre-buried shelf bracket of the different elevation locations of oval petal thin-walled hollow pier shaft
Leg embedded section and lower bracket steel plate box, it connects shelf bracket, and planar graph is radial into groined type, between each shelf bracket
Bridging is connected, Bailey beam and I-steel are installed on each shelf bracket.
Shelf bracket includes horizon bar, long diagonal brace, short brace and bearing pin, and upper bracket embedded section and upper bracket connecting cleat are logical
Bearing pin connection is crossed, horizon bar, long diagonal brace and short brace are by being welded to connect, wherein short brace is welded in the middle part of long diagonal brace,
The lower bracket filter box template of bottom welding of long diagonal brace simultaneously inserts lower bracket steel plate box.Lower bracket filter box template is by I-shaped
Steel cuts away part flange plate, and in its both sides welding shrouding composition.Upper bracket embedded section is that different elevation locations are pre- in pier shaft
Elongated I-steel is buried, planar graph is radial into groined type.Horizon bar is that stiffener and upper bracket are welded in I-steel web both sides
Connecting cleat.Lower bracket steel plate box welds elevation angle angle at 45 ° at opening upper limb.
