The utility model discloses fall to the ground the traditional support and the bracket combines, has both saved the material consumption and can guarantee construction safety again.
Description
Technical Field
The utility model relates to a bridge cable tower entablature construction technology, concretely relates to a supporting structure for superelevation cable tower crossbeam construction.
Background
The cable tower is generally a double-limb structure, and an upper cross beam and a lower cross beam are arranged between two tower columns. The cable tower upper beam is generally constructed by adopting a floor steel pipe pile support or a bracket. The steel pipe pile of the floor stand is supported on the ground and is suitable for construction of a cross beam with a lower height, the bracket is a pre-buried bracket at a certain height on the tower column, and the cross beam construction bracket is erected on the bracket and is suitable for construction of a cable tower cross beam with a higher height. However, for the construction of the upper beam of the ultrahigh cable tower, because the span of the beam is large, the traditional bracket is not enough to support the beam load during construction, and potential safety hazards exist; if the floor stand construction is adopted, the cost is high and the safety control difficulty is high due to the high height of the stand, the material consumption is high, the construction period of the stand is long, and the cost is high.
Disclosure of Invention
The utility model aims to provide a to the traditional difficult problem that falls to the ground support and bracket all are not fit for superelevation cable tower entablature construction, provide one kind and can reduce construction cost, can guarantee construction safety's superelevation cable tower entablature construction support again.
The technical scheme of the utility model as follows:
the utility model provides a superelevation cable tower entablature construction support which characterized in that: the system comprises two floor steel pipe piles arranged between two tower columns along the bridge direction, wherein two brackets which are respectively opposite to the two floor steel pipe piles are respectively arranged below cross beams of the tower columns on opposite side walls of the two tower columns through embedded parts, each bracket supports an inclined strut steel pipe pile, the lower end of each inclined strut steel pipe pile is supported on each bracket, the upper end of each inclined strut steel pipe pile is inclined towards the floor steel pipe pile opposite to the inclined strut steel pipe pile, each floor steel pipe pile is respectively connected with the two inclined strut steel pipe piles opposite to the inclined strut steel pipe pile through a flat link rod, and the pile top of each inclined strut steel pipe pile is parallel to the horizontal plane and is consistent with the pile top height of the floor steel pipe pile; pile top bearing beams are respectively erected between the tops of the two ground steel pipe piles and between the tops of the two inclined strut steel pipe piles supported on the two brackets on the side wall of each tower column, a section steel truss vertical to the pile top bearing beams is horizontally erected on the pile top bearing beams, and a support longitudinal beam, a support cross beam, a distribution beam and a panel are sequentially erected on the section steel truss from bottom to top.
The utility model discloses combined to fall to the ground steel-pipe pile support and bracket advantage between them, the load adopts to fall to the ground steel-pipe pile bearing in the middle of the crossbeam, and both ends load adopts pre-buried bracket on the cable tower, sets up oblique steel-pipe pile bearing, has saved the material that oblique steel pipe falls to the ground the part, and the material consumption is few. The top of the steel pipe pile adopts a profile steel truss structure, the supporting capability is strong, more steel pipe pile supporting points do not need to be arranged, and the construction difficulty and cost are reduced; the support parallel connection and the transverse support rod simultaneously play a role of internal support between the two tower columns, and an internal support structure does not need to be independently arranged to resist thrust generated by inward inclination of the cable tower.

fig. 2 is a schematic side view of the present invention.
Detailed Description
As shown in fig. 1 and 2, the utility model discloses a two pieces of steel-pipe piles 2 that fall to the ground that set up in the middle of two pylons 1 along the bridge direction, lie in pylon crossbeam 3 below on the relative lateral wall of two pylons 1 and install two corbels 4 that respectively just face two steel-pipe piles 2 through the built-in fitting respectively, support an bracing steel-pipe pile 5 on each corbel 4, the lower extreme of bracing steel-pipe pile 5 supports on the corbel 4, and the upper end inclines to the steel-pipe pile 2 that falls to the ground just rather than, and every falls to the ground steel-pipe pile 2 respectively with its two bracing steel-pipe piles 5 that just face to be connected through flat link 6, the pile bolck of every bracing steel-pipe pile 5 is parallel with the horizontal plane, and is unanimous with the pile bolck height of falling to the steel; between the tops of two steel-pipe piles 2 that fall to the ground to and support between two 5 tops of bracing steel-pipe pile on two brackets on every pylon lateral wall, set up pile bolck spandrel girder 7 respectively, the level is set up with pile bolck spandrel girder 8 perpendicular with pile bolck spandrel girder on pile bolck spandrel girder 7, set up support longeron, support crossbeam, distributive girder and panel in proper order from bottom to top on the shaped steel truss 8. And laying a bottom template poured by the upper beam of the cable tower on the panel, or directly adopting the panel as the bottom template.
Because the two towers 1 of the cable tower are in a relatively inclined structure, the two towers have inward inclined thrust. In the common construction of a floor stand and a bracket, an inner support is arranged between two tower columns. The utility model discloses will can the both ends of the flat link rod 6 between the steel-pipe pile that falls to the ground and the bracing steel-pipe pile support respectively on two 1 relative lateral walls of pylon for resist the thrust that the pylon leanin produced.
In order to further resist the thrust generated by inward inclination of the cable tower, a transverse support rod 9 can be arranged on the floor steel pipe pile 2 at certain intervals, and two ends of the transverse support rod 9 are respectively supported on the opposite side walls of the two tower columns 1. When the tower column concrete is poured, the connecting piece can be preset on the side wall of the tower column, so that the connecting piece is conveniently connected with the end part of the transverse supporting rod, and the supporting structure is firmer.
