Abstract
The utility model relates to a road engineering dowel bar localizer. The road engineering dowel bar localizer is mainly composed of two steel pipes, a plurality of steel pipe cross braces and a plurality of localization flat irons. The road engineering dowel bar localizer is characterized in that the two steel pipes are parallelly arranged, a plurality of steel pipe cross braces are respectively welded between the two steel pipes which are parallelly arranged so as to form a main frame, and each steel pipe cross brace is at least welded with two localization flat irons. During construction, the road engineering dowel bar localizer can be used as an auxiliary tool to locate the dowel bar in the concrete and can be used in a cyclic manner. The localizer provided by the utility model can solve the problem that the resource is waste due to the fact that a steel bar support is adopted in the traditional road construction, but also can solve the problem that construction of concrete has to be conducted continuously, thereby saving the construction time and improving working efficiency.
Description
Technical field
The utility model relates to the highway construction dowel steel locator.
Background technology
According to the road design code requirement of implementing in December, 2011, dowel bar requires to have included in the concrete road structure of " extra heavy " category of roads as a kind of new technique, purpose is in order to strengthen the load transmission between the concrete plate, to avoid the plate damage that causes because of road surface plate discontinuity.In road construction, dowel bar generally is positioned at the middle position of concrete plate, as not by means of aid, can't accurately locate pre-buried, the reinforcement fabrication bracing frame is then adopted in construction in the past, and then input is too large, against the principle of saving, and the vibrations of building through concrete and vibrations beam easily cause the dowel bar off normal.
Summary of the invention
The purpose of this utility model provides a kind of aid of reusable edible and can guarantee to install accurately highway construction dowel steel locator in order to solve the installation location difficulty of dowel bar.
The scheme that this practical technical problem with solving adopts is:
The highway construction dowel steel locator, mainly formed by two steel pipes, some steel pipe stulls and some location band iron, it is characterized in that: two parallel placements of steel pipe, weld respectively some steel pipe stulls between the steel pipe of two parallel placements and form body frame, weld at least two location band irons in the every steel pipe stull.
Embedded fluted body is cut in band iron bottom, described location, is convenient to the location colligation of dowel bar reinforcement bar.
Described location band iron size is decided according to the buried degree of depth and the spacing of road dowel bar.
When the road concrete is built, with the dowel bar colligation in being welded on the same location band iron in the steel pipe stull, until concrete vibrate finish after, cut off tie wire, extract the highway construction dowel steel locator, dowel bar namely is embedded in the road concrete deck according to ad-hoc location, dowel steel locator of the present utility model has succinctly easy to operate, practical effect, the installation difficult problem of solution dowel bar in work progress, guarantee dowel bar to lay size smooth, correct position is in order to avoid cause the generation of the disconnected plate situation that the effect of concrete panel stress causes because laying of dowel bar is inaccurate.
The utility model has the advantages that: can satisfy the needs of concrete continuous placing, and can guarantee that dowel bar space orientation is accurate, simple to operation.
Description of drawings
Fig. 1 is the structural representation of specific embodiment of the utility model.
Fig. 2 is A-A sectional drawing of the present utility model.
Fig. 3 is B-B sectional drawing of the present utility model.
Fig. 4 is dowel bar of the present utility model location schematic diagram.
The specific embodiment
The utility model will be further described for the structure accompanying drawing.
Such as Fig. 1, Fig. 2, shown in Figure 3, the utility model mainly is comprised of two steel pipes 1,6 steel pipe stulls 2 and 12 location band irons 3, two steel pipe 1 parallel placements, weld respectively 6 steel pipe stulls 2 between the steel pipe 1 of two parallel placements and form body frame, two location of welding band iron 3 in the every steel pipe stull 2.Described location band iron size is decided according to the buried degree of depth and the spacing of road dowel bar.
The utility model preparation method is as follows:
1. two diameters of two of body frame steel pipes 1 employings are that 40mm, thickness are the parallel placements of 4 mm steel pipes, and length determines that according to the fabric width of Pavement Concrete plate slightly long and fabric width is convenient to be positioned on the concrete form;
2. steel pipe stull 2 employing same models or the diameter of body frame are that 32mm, thickness are the steel pipe of the little model of 5.15mm, and on the steel pipe 1 of two parallel placements of two ends welding, stull steel pipe 2 spacings are identical with the design pitch of dowel bar.
3. weld respectively two location band irons 3 on every stull steel pipe 2, embedded fluted body is cut in band iron bottom, location, is convenient to the location colligation of dowel bar reinforcement bar.
4. the length of location band iron is according to the arrangement Depth determination of dowel bar in the concrete panel.
The constructing operation mode is as follows:
Concrete is not and different according to the position of dowel bar and spacing for locator of the present utility model, and the main body form is constant.
As shown in Figure 4,1. outside the venue with dowel bar 4 reinforcing bar bindings in the location band iron 3 embedded grooves of locator of the present utility model bottom.
2. treat that Pavement Concrete builds when locating to the shrinkage joint, with colligation the locator of dowel bar 4 be pressed in the concrete panel.
3. behind the concrete vibration compacting, cut colligation in the iron wire of stull steel pipe 2 upper ends, manually carry away locator, dowel bar 4 is namely left in the concrete panel.
Claims (2)
1. highway construction dowel steel locator, mainly formed by two steel pipes, some steel pipe stulls and some location band iron, it is characterized in that: two parallel placements of steel pipe, weld respectively some steel pipe stulls between the steel pipe of two parallel placements and form body frame, weld at least two location band irons in the every steel pipe stull.
2. highway construction dowel steel locator according to claim 1, it is characterized in that: embedded fluted body is cut in band iron bottom, described location.
