Description
Technical field:
The present invention relates to bridge substructure construction field more particularly to the pre-buried bracket dresses of king-post upper beam construction bracket
It sets.
Background technique:
Upper beam construction is the important partitioned project of bridge construction.
Being constantly progressive and develop with Chinese society, conventional bridge is no longer satisfied the needs of traffic, therefore, oblique pull
This extra-large bridge of bridge, suspension bridge becomes the important component of current urban traffic road.Cable-stayed bridge, suspension cable bridge tower pier stud
Upper beam height is high, and conventional floor stand needs steel-pipe pile, and high-altitude is spliced section by section, not only wastes material, artificial, it is also desirable to longer
Installation and remove the period, and there are many security risk factors in work progress.
Under this form, high pier king-post upper beam gradually becomes the important selection of upper beam construction, but upper cross using bracket
Beam construction needs stress of taking root on king-post using bracket.Therefore, how to ensure to be set as on high tower tower body bracket construction by
The device of power becomes the key of king-post bracket construction.
Summary of the invention:
The technical problems to be solved by the present invention are: providing a pre-buried bracket device of king-post upper beam construction bracket, it is intended to
Enough bearing capacities are provided for king-post upper beam bracket, bracket is allow to weigh the various loads in upper beam work progress.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions: the pre-buried bracket stress
Face provides impetus；In described pre-embedded steel slab insertion high pier construction concrete；The bracket backing plate 1 is pre-buried to lie in a horizontal plane in
The steel plate with a thickness of 2-4cm immediately below steel plate is welded with pre-embedded steel slab；Bracket backing plate 2 is close to high pier concrete surface, and upper end is same
Bracket backing plate 1 intersects vertically and welds.Bracket gusset is triangular steel plate, vertical to place, with ox bracket backing plate 1 and bracket backing plate
2 weld, and are respectively provided with one piece of bracket gusset under every piece of pre-embedded steel slab.
Preferably, pre-buried bracket stress surface provides impetus, and bracket is integrally welded with pre-buried bracket stress surface；
Preferably, described pre-embedded steel slab is to be inserted into high pier construction concrete, pre-buried steel with a thickness of 5-15cm thick steel plate
The length of plate, the size highly according to offer support force are determining, and quantity is two or more, but in unified absolute altitude；
Preferably, the bracket backing plate 1 is welded to connect with pre-embedded steel slab.
Preferably, the bracket backing plate 2 is close to king-post concrete surface according to upper end is welded with bracket backing plate 1.
Preferably, the bracket gusset is right angled triangle, and the same pre-embedded steel slab of quantity is mounted on immediately below pre-embedded steel slab,
It is welded respectively with bracket backing plate 1 and bracket backing plate 2 on two sides.
Preferably, the bracket gusset lateral is angle steel, and with bracket link of boards, lateral between different bracket gussets should be
On one horizontal line.
The invention has the beneficial effects that: pre-embedded steel slab is main bearing member, and with a thickness of 5-15cm, pre-buried hole is less than
King-post main reinforcement spacing, therefore pre-embedded steel slab installation will not separate king-post steel plate；Bracket backing plate 1 is mounted below pre-embedded steel slab, can
Multiple pre-embedded steel slabs to link into an integrated entity well, and play the role of stress distribution；The installation of bracket gusset can be fine
Ground reduces the bending stress that pre-embedded steel slab is subject to, and the pressure that pre-embedded steel slab is subject to, which is converted into, pushes away the level of king-post surface concrete
Power；Bracket backing plate 2 is close to concrete cylinder, and welds with bracket gusset and bracket backing plate, can be transmitted to bracket gusset
The power of king-post concrete surface plays the role of stress dispersion；Bracket gusset lateral is integral by each link of boards, can be well
Improve the stability of bracket gusset.Pre-buried bracket overall structure stable connection, each member stress is succinct, and structure is simple, but can
To bear great load.
Detailed description of the invention:
The following further describes the present invention with reference to the drawings.
Fig. 1 is upper beam bracket overall floor plan, for a kind of pre-buried bracket of king-post upper beam construction bracket of the present invention
Setting position schematic diagram；
Fig. 2 is for a kind of pre-buried bracket device side elevational view of king-post upper beam construction bracket of the present invention；
Fig. 3 is for a kind of pre-buried bracket device front elevation view of king-post upper beam construction bracket of the present invention；
In figure: 1, king-post concrete surface；2, pre-buried bracket stress surface；3, pre-embedded steel slab；4, bracket backing plate 1；5, bracket muscle
Plate；6, bracket backing plate 2；7, bracket gusset lateral.
Specific embodiment:
Fig. 1 be upper beam construction bracket, Fig. 2, Fig. 3 be pre-buried bracket side elevation and front elevation view, including pre-buried bracket by
Power face, pre-embedded steel slab, bracket backing plate 1, bracket gusset, bracket backing plate 2, bracket gusset lateral.The pre-buried bracket stress surface will
Bracket is connected with bracket；The pre-embedded steel slab is main bearing member, is inserted into the length in concrete and is greater than outside concrete
Length；Bracket backing plate 1, bracket backing plate 2, bracket gusset and the interconnection of bracket gusset lateral under pre-embedded steel slab is integral, rises
Fine stress and intermal force are arrived.
It is integral in rear long paperback after the accurate processing and fabricating of pre-buried each component of bracket device, then integral installation to king-post.
Its specific mounting means is as follows:
Before pre-buried bracket installation, it should when king-post concrete construction, pre-buried box is set in design position, it is pre-buried
Box is made of steel plate, need to be installed in place in king-post concrete construction and be must assure that pre-buried box fixation, it is ensured that most
Pre-buried bracket installation site is accurate eventually.
Bracket provides job platform and armored concrete mounting bracket for upper beam construction, is tiltedly propped up by main spandrel girder, bracket
Leg and web member composition.Spandrel girder and supporting leg are the main bearing member of bracket, and the master that pre-buried bracket is mainly same as above crossbar bracket holds
Chong Liang is connected with oblique supporting leg, completes the transmitting of power.After pre-buried box is installed in place, pre-buried bracket device integral installation is arrived
Position, then will be in bracket integral installation to pre-buried bracket.
By pre-buried bracket device, upper beam is directly anchored on king-post, since its king-post height is high, keeps bracket fine
Ground reduces waste of material caused by bracket installation from top to bottom and artificial, mechanical investment, considerably reduces construction cost.
It is emphasized that: the above is only presently preferred embodiments of the present invention, not make in any form to the present invention
Limitation, any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention,
All of which are still within the scope of the technical scheme of the invention.
