Abstract
The utility model relates to the field of road engineering, in particular to a ballastless road bed template fixed device, which comprises an angle bracket, wherein an adjusting wedge is arranged between the inner side of the angle bracket and a template, and a vertical rod which is inserted into the foundation is arranged on the lower portion of the angle bracket. The ballastless road bed template fixed device uses the angle bracket to support, and forms an adjustable and reliable template support device by adjustment of the adjusting wedge. The ballastless road bed template fixed device is excellent in stability and is easier to move compared with supporting of a steel pipe or a square wood simultaneously.
Description
Technical field
The utility model relates to the highway construction field, and is particularly a kind of without tiny fragments of stone, coal, etc. railway roadbed fixing templates.
Background technology
In the Construction of Ballastless Track process, the support of sleeper 5 by support member 6, scale batten 7, template 2 makes sleeper 5 be suspended in ground 3 tops, then need to 2 concretings of two templates, after building complete concrete setting, remove scale batten 7 and template 2, sleeper 5 is fixed on ground 3 by the concrete that solidifies.
In process due to concreting, template 2 there is certain impact force, therefore need to before building, template 2 be reinforced.Existing method adopts steel pipe to support, and namely one end and template 2 offset, and the other end is against on gutter 4, and along the arranged direction of sleeper 5, template 2 is implemented compartment and support supporting, the same position that supports, the one high and one low layout of steel pipe, as shown in Figure 1.Due to the steel pipe straight line, easily stressedly be shifted, warpage, effectively support shuttering 2, make the easy positioning of template 2, can not guarantee railway roadbed concrete overall appearance and quality; Because steel pipe is longer, mobile inconvenient simultaneously.
The utility model content
It is a kind of without tiny fragments of stone, coal, etc. railway roadbed fixing templates that the purpose of this utility model is to provide, fixing reliable, movement for convenience detach.
For reaching above effect, the technical solution adopted in the utility model is: a kind of without tiny fragments of stone, coal, etc. railway roadbed fixing templates, comprise angular support frame, between the vertical member concordant with the template plate face of vertically-arranged and template, the adjustment voussoir is set on described angular support frame, the bottom of angular support frame is provided with the vertical rod of inserting in ground.
Compared with prior art, there is following technique effect in the utility model:
Use angular support frame as support, by adjusting the adjusting of voussoir, consist of adjustable and reliable mould plate supporting device; Simultaneously compared to steel pipe, good stability, and easily mobile.
Description of drawings
Fig. 1 is the prior art structural representation;
Fig. 2 is the utility model structural representation;
Fig. 3 is the A side schematic diagram of Fig. 2;
Fig. 4 is the B side schematic diagram of Fig. 2.
The specific embodiment
Below in conjunction with Fig. 2 to Fig. 4, the utility model is done being described in further detail:
Consult Fig. 2, a kind ofly comprise angular support frame 10 without tiny fragments of stone, coal, etc. railway roadbed fixing templates, arrange between the vertical member 11 that described angular support frame 10 is concordant with the template 30 plate faces of vertically-arranged and template 30 and adjust voussoir 20, said vertical member 11 can be rod member herein, and the section bars such as channel-section steel commonly used both can.As long as guarantee that it by adjusting voussoir 20 fixed forms 30, guarantees that when concreting, template 30 can not be shifted.The bottom of angular support frame 10 is provided with the vertical rod 14 of inserting in ground 40, and vertical rod 14 is used for angular support frame 10 is fixed with ground relatively, and fixed support easily, avoided of the prior art and must provide fulcrum to an end of rod member so at any time.Described angular support frame 10 encloses for vertical member 11, horizontal element 12, support member 13 right-angled triangle that forms, because leg-of-mutton structure is more stable.For effective support of guaranteeing 11 pairs of templates of vertical member, against, upper and lowerly between described vertical member 11 and template 30 respectively arrange one and adjust voussoir 20, way is preferably, be that template 30 lower sides arrange one and adjust voussoir 20 near ground 40 places, also arrange one near the upside place of template 30 and adjust voussoir 20.
Described vertical member 11, horizontal element 12, support member 13 are rod member, all adopting diameter in the present embodiment is that the reinforcing bar of 16mm is made, its connecting place welds together, vertical rod 14 is postponed consistent with vertical member 11 above-below directions, work in-process, vertical rod 14 is same section bar with vertical member 11, the processing of being more convenient for like this.In order to increase the adjustability of A-frame 10, arrange between described horizontal element 12 and ground 40 and adjust voussoir 20.Described adjustment voussoir 20 is made of two timber wedge 21a, 21b that cooperatively interact, by adjusting the relative position of timber wedge 21a, 21b, make the distance between vertical member 11 and template 30, horizontal element 12 and ground 40 change, in use, regulate timber wedge to correct position, make template 30 obtain effectively supporting getting final product.
In the present embodiment, A-frame 10 is fixing with respect to ground 40 by vertical rod 14, also can take out easily when making like this vertical rod 14 conveniently to insert and to remove.
