Description
Technical field
The utility model relates to the improvement of road bridge temporary support, particularly a kind of bridge construction steel cylinder temporary support.
Background technology
The road bridge temporary support of current use is mostly plancon temporary support, brick temporary support, sulphur-bonded mortar temporary support, but these three kinds make all existing defects temporarily, although but plancon temporary support material is easily chosen there is elastic deformation, thus affect beam position, according to brick temporary support, then its compressive strength is low, according to sulphur-bonded mortar temporary support, then need to producer order and also cost high.
Utility model content
The purpose of this utility model is to solve the problem, and devises a kind of bridge construction steel cylinder temporary support.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of bridge construction steel cylinder temporary support, comprise for carrying bent cap 1 weight and being positioned at pre-embedded steel slab 2 at the bottom of the beam of bent cap two ends soffit and two abutments 3 being positioned at ground, pre-embedded steel slab 2 at the bottom of described beam and be fixedly connected with by two temporary supports between corresponding abutment 3 with it, described temporary support be respectively weld in the top and bottom of steel drum one block plate composition structure, described steel drum 4 be employing heavy wall seamless steel pipe.
The upper steel plate of described temporary support adopts pre-embedded steel slab 2 at the bottom of the mode of discontinuous welding and beam to weld together, and the lower steel plate of described temporary support is fixedly connected with abutment 3 by bolt.
The space existed between pre-embedded steel slab 2 at the bottom of the upper steel plate of described temporary support and beam, fills the mixture of different-diameter reinforcing bar and bearing mortar in space.
The wall thickness of seamless steel tube of described temporary support is 13mm-16mm, and external diameter is 23mm-27mm.
The thickness of described steel plate 5 is 19mm-25mm.
The bridge construction steel cylinder temporary support utilizing the technical solution of the utility model to make, technique is simple, cost is low, and do not exist because elastic deformation affects the problem of beam position, compressive strength is high, practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of bridge construction steel cylinder temporary support described in the utility model;
In figure, 1, bent cap; 2, pre-embedded steel slab at the bottom of beam; 3, abutment; 4, steel drum; 5, steel plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is specifically described, as shown in Figure 1, a kind of bridge construction steel cylinder temporary support, comprise for carrying bent cap 1 weight and being positioned at pre-embedded steel slab 2 at the bottom of the beam of bent cap two ends soffit and two abutments 3 being positioned at ground, pre-embedded steel slab 2 at the bottom of described beam and be fixedly connected with by two temporary supports between corresponding abutment 3 with it, described temporary support be respectively weld in the top and bottom of steel drum one block plate composition structure, described steel drum 4 be employing heavy wall seamless steel pipe; The upper steel plate of described temporary support adopts pre-embedded steel slab 2 at the bottom of the mode of discontinuous welding and beam to weld together, and the lower steel plate of described temporary support is fixedly connected with abutment 3 by bolt; The space existed between pre-embedded steel slab 2 at the bottom of the upper steel plate of described temporary support and beam, fills the mixture by different-diameter reinforcing bar and bearing mortar in space; The wall thickness of seamless steel tube of described temporary support is 13mm-16mm, and external diameter is 23mm-27mm; The thickness of described steel plate 5 is 19mm-25mm.
The feature of the present embodiment is, for carrying bent cap weight and being positioned at pre-embedded steel slab at the bottom of the beam of bent cap two ends soffit and two abutments being positioned at ground, pre-embedded steel slab at the bottom of beam and be fixedly connected with by two temporary supports between corresponding abutment with it, temporary support be respectively weld in the top and bottom of steel drum one block plate composition structure, steel drum is the seamless steel pipe adopting heavy wall, technique is simple, cost is low, do not exist because elastic deformation affects the problem of beam position, compressive strength is high, practical.
In the present embodiment, steel drum is made by the seamless steel pipe of heavy wall, respectively weld a block plate in steel drum upper and lower surface and make temporary support, adopt the mode of discontinuous welding to weld together pre-embedded steel slab at the bottom of temporary support and beam, at the bottom of temporary support and beam, the mixture of different-diameter reinforcing bar and bearing mortar is filled in the gap of pre-embedded steel slab.
In the present embodiment, the temporary support adopting steel cylinder to make, more traditional support material is easily chosen, processing technology is simple, cost is low and secure to the precast beam beam beam position that falls, ensure that permanent bearing not because of the beam that falls is damaged or permanent bearing by influence of shear force quality.
In the present embodiment, pre-embedded steel slab at the bottom of beam and bearing upper steel plate clog the mixture of different-diameter reinforcing bar and bearing mortar, technological innovation, improve packing compressive strength, ensure that packing quality, reduce bridge runtime bearing repair rate, further ensure bridge security of operation simultaneously.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model; those skilled in the art all embody principle of the present utility model to some variations that wherein some part may be made, and belong within protection domain of the present utility model.
