Abstract
The utility model relates to a bridge beam supports base stone preformed hole special mould, the outer circumference of steel drum is the round platform structure, and just the upper end diameter is greater than the lower extreme diameter, and the department is equipped with vertically T type positioning bolt at the upper surface center of steel drum. This special mould is repeatedly usable not only, has practiced thrift construction material, and the location is accurate moreover to a plurality of hole sites of accurate positioning have simultaneously improved the efficiency of construction that the preformed hole set up.
Description
Technical field
This utility model relates to a kind of bridge pad pinner preformed hole particular manufacturing craft, for the mould of high-speed railway, common railway and highway bridge pier top pinner domestic demand advance reservation hole site design.
Background technology
It is pre-buried that existing preformed hole mostly adopts PVC plastic pipe to fill sand sealing two ends, and weakness is easy off normal and is not easy to fix, and taking out pvc pipe after generally having constructed wastes time and energy, and stays and also affects quality in pinner.
Another kind of form is to adopt steel pipe can fix welding, and positioning performance is good, but takes out difficulty after having constructed more greatly, more wastes material, so common engineering construction seldom adopts.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of bridge pad pinner preformed hole particular manufacturing craft, this particular manufacturing craft is not only reusable, has saved construction material, and registration, and position, multiple hole can be accurately positioned simultaneously, improve the efficiency of construction that preformed hole is arranged.
For solving problem above, concrete technical scheme of the present utility model is as follows: a kind of bridge pad pinner preformed hole particular manufacturing craft, the excircle of steel drum is frustum cone structure, and back cut diameter is more than lower port diameter, is provided with vertical T-shaped bolt in the upper surface center of steel drum.
Being provided with location-plate in the cavity of described steel drum, the central axis of location-plate is provided with screwed hole, and the upper surface at steel drum is provided with the upper cover plate with screwed hole of centre, the screwed hole of centre of bolt traverse location-plate and upper cover plate.
The bottom surface of described steel drum is provided with circular platform type through hole, is provided with bottom movable part in circular platform type through hole, and the outer circumferential shape of bottom movable part is consistent with the bottom outlet shape of steel drum, and in bottom, movable part upper surface is provided with grab, and the bolt head of bolt snaps onto in grab.
This bridge pad pinner preformed hole particular manufacturing craft adopts the steel drum structure corresponding with the diameter of preformed hole, and positioned by bolt thereon, being extracted by entirety steel drum after use and by bolt, the frustum cone structure of steel drum is that entirety is extracted and provided convenience.
Arranging location-plate and upper cover plate on steel drum, and central axis has screwed hole, bolt passes through screwed hole, it is ensured that the axiality with steel drum of bolt.
Movable part bottom drum head is arranged, and the bolt head of bolt is blocked by grab, by rotating bolt after construction, steel drum entirety can be screwed out, improve efficiency of construction.
Accompanying drawing explanation
Fig. 1 is the structural representation of bridge pad pinner preformed hole particular manufacturing craft.
Fig. 2 is the upward view of bridge pad pinner preformed hole particular manufacturing craft.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of bridge pad pinner preformed hole particular manufacturing craft, the excircle of steel drum 1 is frustum cone structure, and back cut diameter is more than lower port diameter, location-plate 3 it is provided with in the cavity of steel drum 1, the central axis of location-plate 3 is provided with screwed hole, upper surface at steel drum 1 is provided with the upper cover plate 4 with screwed hole of centre, T-shaped bolt 2 traverse location-plate 3 and the screwed hole of centre of upper cover plate 4, and the thread head part of bolt stretches out upper cover plate 4, thinner thickness due to location-plate 3 and upper cover plate 4, can at position welded nut corresponding to centre bore, to increase the length of threaded engagement.It is provided with circular platform type through hole in the bottom surface of steel drum 1, bottom movable part 5 it is provided with in circular platform type through hole, the outer circumferential shape of bottom movable part 5 is consistent with the bottom outlet shape of steel drum 1, is provided with grab 6 at bottom movable part 5 upper surface, and the bolt head of bolt 2 snaps onto in grab 6.
During use, bridge pad pinner preformed hole particular manufacturing craft being completed rear entirety and is placed in concrete, upper cover plate surface flushes with concrete surface.After concrete setting, bolt 2 is rotated by external force, bolt 2 is made to move down, after bolt is pressed to the upper surface of bottom movable part 5, continuing to rotate bolt 2, steel drum 1 moves up under the effect of screw thread rotation power, steel drum 1 and bottom movable part 5 depart from, and screwed out concrete reserving hole, it is achieved and the demoulding, then further take out bottom movable part 5 and bolt 2.In like manner, bolt 2 may be used without the hydraulic means replacements such as hydraulic jack, it is achieved mechanical stripping, saves labour force.
When preformed hole is positioned, can first in the position of the multiple hole of steel plate upper outlet, ensure the position relationship that hole is mutual, then the bolt in each bridge pad pinner preformed hole particular manufacturing craft is connected with hole, entirety falls in concrete mud again, after concrete setting, namely ensure that the positional precision of preformed hole.
In sum, bridge pad pinner preformed hole particular manufacturing craft can repeat to be suitable for, and can be accurately positioned before construction, and maximum feature is to position by several preformed holes simultaneously, as long as can fix with a simple beam simultaneously, error is within millimeter.And the structure that helicitic texture dismounting is overall can be passed through, not only save material and improve dismounting efficiency.
