Background technique
The installation of road preliminary bracing steel arch-shelf is the critical process of constructing tunnel, due to tunneling operation narrow space, by tunnel
Operation side limitation, Tunnel steel arch-shelf are had to segmental machining, on-site consolidation.
Due to steel arch-shelf connecting plate and steelframe butting error, hole position error, assembled error, the initial stage branch of on-site consolidation is caused
The connection of steelframe connecting portion is not close, and connecting plate bolt hole misplaces, and bolt installation is not in place and other issues is protected, at the beginning of influencing tunnel
Phase supporting steelframe entirety stress causes preliminary bracing steelframe connecting portion weak load-bearing point.Currently, Tunnel steel arch
Frame connecting plate and arch generally use the mode of scribing line welding, and without fixed processing mold, spiro keyhole position is more casual, and scene is spelled
Dress is difficult, assembled of poor quality, and opening often occurs for connecting plate, dislocation, connection bolt installs not on, causes splicing low efficiency, welds
Quality not can guarantee.
Utility model content
For above situation, for the defect for overcoming the prior art, the utility model provides tunnel steel arch frame junction steel plate
Fast accurate positioning device；The quick of junction steel plate is realized well, and precise positioning improves splicing when steel arch-shelf is set up
Efficiency.
Its technical solution solved includes laterally disposed I-steel, and I-steel upper ends have positioning mold, positioning mould
Tool is the channel steel structure of U-shaped, and positioning mold includes the bottom plate being bonded with I-steel upper end and vertically places above bottom plate
Two vertical plates, the bottom plate lower end of positioning mold are equipped with the locating clamp plate being placed in outside I-steel, run through on the bottom plate of positioning mold
There is mold fixing axle, the transverse slat of I-steel is run through and between the transverse slat of I-steel to be threadedly coupled in the lower end of mold fixing axle,
Positioning pin is fixed on one cant board of positioning mold.
The utility model clever structure, realizes the quick of junction steel plate well, and precise positioning improves steel arch-shelf frame
If when splicing efficiency.
Detailed description of the invention
Fig. 1 is the utility model overall schematic I.
Fig. 2 is the utility model entirety stereoscopic schematic diagram II.
Fig. 3 is 2 stereoscopic schematic diagram A of the utility model positioning mold.
Fig. 4 is 2 stereoscopic schematic diagram B of the utility model positioning mold.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
By Fig. 1-4 it is found that the utility model includes laterally disposed I-steel 1,1 upper ends of I-steel have positioning mold
2, positioning mold 2 is the channel steel structure of U-shaped, and positioning mold 2 includes on the bottom plate 3 and bottom plate 3 being bonded with 1 upper end of I-steel
Two vertical plates 4 that Fang Shuxiang is placed, 3 lower end of bottom plate of positioning mold 2 are equipped with the locating clamp plate 5 being placed in outside I-steel 1, positioning
Through there is a mold fixing axle 6 on the bottom plate 3 of mold 2, the lower end of mold fixing axle 6 through I-steel 1 transverse slat and with I-steel 1
Transverse slat between to be threadedly coupled, on a cant board 4 of positioning mold 2 be fixed with positioning pin 7.
In order to keep the fixation of positioning mold 2 more firm, 5 locating clamp plate 5 of locating clamp plate is added using 10mm steel plate
Work, the spacing between two locating clamp plates 5 are 1mm bigger than 1 width dimensions of I-steel.
For the ease of welding steel to just, it is symmetrically arranged with before and after the positioning pin 7 on the vertical plate 4 of the positioning mold 2
Two positioning pins 7, positioning pin 7 are placed in vertical plate 4 close to 4 front and rear sides edge of vertical plate.
The vertical plate 4 that the positioning mold 2 is equipped with 7 side of positioning pin is concordant with a side end face of I-steel 1.
The positioning mold 2 is made of 20# channel steel.
The positioning pin 7 is welded on the vertical plate 4 of positioning mold 2.
Positioning mold 2 is caught in the I-steel 1 processed, due to positioning mould when specifically used by the utility model first
3 lower end of bottom plate of tool 2 is equipped with locating clamp plate 5, can be very good the outside for being stuck in I-steel 1, and having for adjustment positioning mold 2 is fixed
Mold fixing axle 6 is tightened after the side of the vertical plate 4 of position pin 7 is concordant with 1 end of I-steel mold is fixed, prevent mold from sending out
Raw movement；Furthermore pin hole is being drilled out in advance on needing the junction steel plate 8 welded, positioning pin 7 need to be according between steel plate design aperture
Away from being precisely welded and fixed, the diameter of positioning pin 7 is 0.5mm smaller than steel plate design bore size；The position of pin hole and positioning pin 7
It is corresponding, it is bonded the end face of junction steel plate 8 with the end of I-steel 1 concordantly, is realized by the cooperation of positioning pin 7 and pin hole 9
The positioning of junction steel plate 8；8 two sides of steel plate leakage part is welded to connect after fixation first, to steel plate and 1 fix tightly of I-steel
Fixing mould is removed rearward, continues 1 two sides rest part of welding H-bar, and last 1 web part of welding H-bar is thus complete
It is connect at steel arch-shelf junction steel plate 8 with quick, the precise positioning of I-steel 1, ensure that can smoothly, quickly when steel arch-shelf is set up
Splicing.
The utility model is by devising positioning mold 2, can be effective when welding to steel arch-shelf junction steel plate 8
Guarantee junction steel plate 8 be bonded with the positioning of I-steel 1, while by between the pin hole on positioning pin 7 and junction steel plate 8
Location fit, the influence for effectively preventing the shaking and thermal deformation of junction steel plate 8 in the welding process from generating, to pros
Just, welding efficiency significantly improves.
The utility model clever structure, realizes the quick of junction steel plate well, and precise positioning improves steel arch-shelf frame
If when splicing efficiency.
