Embodiment Construction
[0036] See Figure 1 to Figure 5 , the stereotyped bracket template of the present invention is an integral strip template made of rubber and extending in the same direction along the track length direction. It includes a template body 10. The forming surface 11 and the formwork body 10 are provided with an accommodating chamber 12 extending in the same direction along the length direction of the rail for accommodating the rail head and the upper half of the rail waist, and the bottom of the accommodating chamber 12 is provided with an open groove 13, and the open groove 13 The width D2 of the rail is equal to the width of the rail waist d2, and the top of the template body 10 is integrally provided with a left-right symmetrical horizontal flange protrusion 14, and the bottom of the horizontal flange protrusion 14 is flush with the top plane of the rail base of the track, so that The protruding portion 14 of the horizontal flange joins the top chamfer structure of the forming ...

The invention provides a shaped support template. The shaped support template can be used for resolving the problems caused by the adoption of a split bubble template in the prior art that the construction is complicated, and stability and reliability of guide track positioning are poor. The shaped support template prepared from rubber is an integrated strip template extending in the lengthwise direction of a track and comprises a template body provided with forming surfaces matched with the groove faces of a guide groove to be formed. A containing cavity extending and running through in the lengthwise direction of the track is formed in the template body and is used for containing a track head and the upper half part of a track waist. An open groove of which the width is the same with that of the track waist is formed in the bottom of the containing cavity. The top of the template body is integrally provided with horizontal flange bulges which are bilaterally symmetrical. When the assembly is finished, the bottoms of the horizontal flange bulges flush with the plane of the top of a track base of the track. The invention further provides a rubber-injection process for rubber wheel type track construction using the shaped support template.
Description
technical field [0001] The invention relates to the technical field of track construction, in particular to the technical field of rubber-wheeled track construction tooling, in particular to a shaped support template and a glue injection process for rubber-wheeled track construction using the template. Background technique [0002] In the construction process of the rubber-wheeled monorail track, it is usually necessary to pour resin glue in the track groove of the track base. After the resin glue solidifies and hardens, an insulating filling layer with a guide groove structure is formed in the track groove. On the one hand, the insulating filling layer will The lower part of the track and the fastener device used to fix the track are isolated from the outside world, effectively preventing the stray current generated by the train running on the track from corroding the metal pipe network around the track. On the other hand, the guide groove of the insulating filling layer can...
