Description
Technical field
The utility model belongs to a kind of catenary mast foundation bolt group finished product protective device.
Background technique
In the construction of railway engineering mast foundation for overhead contact wire system, by the catenary mast foundation bolt group finished product precisely welded
(referred to as: foundation bolt group), which needs integrally to transport from steel bar meter field to scene, carries out installation, but is transporting and constructing
Each bolt column of Cheng Zhong, composition foundation bolt group easily deform, and the top screw thread of each bolt column easily causes destruction and pollution, and
Each bolt column is also difficult to position in die holder in casting process, is difficult to get a desired effect after causing installation, causes to construct
Error is big.
Summary of the invention
The purpose of this utility model is to design a kind of catenary mast foundation bolt group finished product protective device, can be to composition ground
Each bolt column of foot bolt group carries out effective position and protection, has structure simple, and protection is firm, accurate positioning and uses effect
The good advantage of fruit.
For this purpose, the utility model is made of screw thread steel bushing and positioning plate, in which:
Screw thread steel bushing is used to protect the top of each bolt column of foundation bolt group, screw thread steel bushing body cylindrical in shape, screw thread
The middle part of steel bushing is band internal thread through-hole, and the upper end of screw thread steel bushing is equipped with the cap that keeps off the rain.Positioning plate is for positioning lower margin
Bolt group, positioning plate are located at the top of each bolt column of foundation bolt group, and positioning plate is in half elliptic, and the middle part of positioning plate is equipped with
Pouring hole corresponds to each bolt column on the positioning plate on pouring hole periphery and is equipped with several jacks for the insertion of each bolt column upper end, positioning
The periphery of plate corresponds to each screw hole on die holder upper end edge equipped with several fixation holes.
The positioning plate is the steel plate of 1cm thickness.The fixed hole position is on the positioning plate of jack outer periphery.It is described
The cap that keeps off the rain area be greater than screw thread steel bushing cross-sectional area.
Above structure has reached the purpose of this utility model.
The utility model can carry out effective position and protection to each bolt column of composition foundation bolt group, can make to form lower margin
Each bolt column of bolt group is unlikely to deform, and threaded portion is survivable and pollutes, while guaranteeing the exposed length in threaded portion in casting process
Degree meets construction requirement, has structure simple, and protection is firm, accurate positioning and the good advantage of using effect.
Detailed description of the invention
Fig. 1 is the positioning plate structure schematic diagram of the utility model.
The screw thread steel bushing structural schematic diagram of Fig. 2 the utility model.
Fig. 3 is the structural schematic diagram of the positioning plate positioning stone bolt group of the utility model.
Fig. 4 is structural schematic diagram when pouring of the utility model.
Specific embodiment
As shown in Figures 1 to 4, a kind of catenary mast foundation bolt group finished product protective device, by 7 He of screw thread steel bushing
Positioning plate 4 is formed, in which:
Screw thread steel bushing is used to protect the top of each bolt column 5 of foundation bolt group, and the lower part of each bolt column is in interval distance
From transverse steel circle 6 is equipped with, for fixing each bolt column.The top of each bolt column be external thread part 1, screw thread steel bushing can with it is outer
Threaded portion is spirally connected.Screw thread steel bushing body cylindrical in shape, the middle part of screw thread steel bushing are band internal thread through-hole 71, screw thread steel bushing
It can be rotated with by through-hole on the top of each bolt column.The upper end of screw thread steel bushing is equipped with the cap 72 that keeps off the rain, the face of the cap that keeps off the rain
Product is greater than the cross-sectional area of screw thread steel bushing, and the cap that keeps off the rain is used to close upper surface and the rainwater-proof of screw thread steel bushing.
Positioning plate is used for positioning stone bolt group.Positioning plate is located at the top of each bolt column of foundation bolt group.Positioning plate
In half elliptic, the middle part of positioning plate is equipped with pouring hole 8, and each bolt column is corresponded on the positioning plate on pouring hole periphery equipped with several confessions
The jack 41 of each bolt column upper end insertion.The periphery of positioning plate corresponds to each screw hole on 11 upper end edge of die holder equipped with several fixation holes
3.The positioning plate is the steel plate of 1cm thickness.The fixed hole position is on the positioning plate of jack outer periphery.
As shown in Figure 3 to Figure 4, in use, being first screwed into a holding nut on each bolt column top of foundation bolt group, guarantee
In the same plane, the length of the bolt column of holding nut upper end is equal to or slightly less than screw thread steel bushing for the upper surface of each holding nut
The length of cylinder.By each receptacle alignment of positioning plate and sleeve is on corresponding each bolt column, and the lower end surface top of positioning plate is held each
The upper surface of holding nut, then each bolt column top exposed in the upper surface of positioning plate are screwed into a location nut 2, complete positioning
Positioning of the plate to each bolt column of foundation bolt group.
Then, each bolt column top exposed in location nut upper surface is screwed into screw thread steel bushing, completes screw thread steel bushing
Jacketed protection to each bolt column of foundation bolt group.The foundation bolt group for installing positioning plate and screw thread steel bushing additional is transported to again and is applied
Work scene passes through consolidating on positioning plate with screw for in the foundation bolt group of positioning plate and screw thread steel bushing merging die holder 11
Determining hole, peripherally corresponding screw hole 9 is fixed with die holder upper end, and fixed foundation bolt group is in die holder space 10.In the middle part of from positioning plate
Pouring hole into die holder casting concrete, the top lower end of fixed foundation bolt group is in concrete.Wait upon it is concrete curing after, tear open
Die holder unloads screw thread steel bushing and positioning plate.
In short, the utility model can carry out effective position and protection to each bolt column of composition foundation bolt group, there is knot
Structure is simple, and protection is firm, accurate positioning and the good advantage of using effect.
