The utility model has simple structure, can fix the template of the cushion stone, ensures the precision of the reserved hole channel of the support and ensures the construction quality of the cushion stone.
Description
Technical Field
The utility model belongs to the technical field of bridge construction, relates to construction of pier top base stones, and particularly relates to a pier top base stone template and a support preformed hole positioning device.
Background
The top of the pier is usually provided with a cushion stone, the cross section of the cushion stone is generally rectangular, and support reserved holes are respectively arranged on the cushion stone corresponding to 4 corners and used for installing supports. The construction of the cushion stone is a prerequisite condition for the construction of the upper structure of the subsequent bridge, so that the requirement on the positioning precision of the cushion stone template and the reserved hole channel is very strict. At present, a PVC pipe or a steel pipe is usually buried in the position of a reserved hole of a support on a cushion stone for positioning in construction, but when the cushion stone is poured with concrete, the cushion stone template and the reserved hole of the support are easy to deviate due to concrete vibration and lateral pressure of the concrete, and quality and potential safety hazards are caused to subsequent support installation and bridge superstructure construction.
Disclosure of Invention
The utility model aims to solve the problems and provides a pier top cushion stone template and a support preformed hole positioning device, so that the pouring quality of a cushion stone and the precision of a support preformed hole channel are ensured.
The technical scheme of the utility model is as follows:
the utility model provides a mound top stone template and support preformed hole positioner which characterized in that: the template positioning device comprises two template positioning ribs which are arranged in parallel, wherein the length of each template positioning rib is greater than that of a pier top cushion stone, the distance between the two template positioning ribs is equal to the center distance of reserved holes of two supports in the transverse bridge direction or the forward bridge direction on the pier top cushion stone, and a connecting rib is welded between the two template positioning ribs; 1 to 2 anchoring ribs are respectively arranged at two ends of each template positioning rib, and the upper end of each anchoring rib is welded with the template positioning rib; two hanging ribs are welded at two ends close to the template positioning rib respectively, the upper ends of the two hanging ribs are welded with the template positioning rib, the lower ends of the two hanging ribs are welded with a circular positioning ring, the outer diameter of the positioning ring is equal to the inner diameter of the support preformed hole, and the circle center distance of the two positioning rings is equal to the center distance of the two support preformed holes in the transverse bridge direction or the forward bridge direction.
The utility model has simple structure and convenient installation, is mainly manufactured by using the steel bars on the construction site, and can achieve the aims of fixing the base stone template and ensuring the precision of the manufactured reserved hole channel when the concrete of the pier body and the pier top base stone is poured, thereby ensuring the construction quality of the base stone.

Detailed Description
As shown in fig. 1 and 2, the utility model comprises two template positioning ribs 1 which are arranged in parallel, wherein the length of the template positioning ribs is greater than that of the pier top cushion stone, the distance between the two template positioning ribs is equal to the center distance of reserved holes of two supports in the transverse bridge direction or the forward bridge direction on the pier top cushion stone, and a connecting rib 2 is welded between the two template positioning ribs; 1 to 2 anchoring ribs 3 are respectively arranged at two ends of each template positioning rib, and the upper end of each anchoring rib is welded with the template positioning rib; two ends close to the template positioning ribs are respectively welded with two hanging ribs 4, the upper ends of the two hanging ribs are welded with the template positioning ribs, the lower ends of the two hanging ribs are welded with a circular positioning ring 5, the outer diameter of the positioning ring is equal to the inner diameter of the support preformed hole, and the circle center distance of the two positioning rings on each template positioning rib is equal to the center distance of the two support preformed holes in the transverse bridge direction or the forward bridge direction.
The holding ring is used for fixing a position the support preformed hole registration pipe, and in order to guarantee that the holding ring can be smoothly arranged in the support preformed hole registration pipe, two hanging ribs can be arranged in a shape like the Chinese character 'ba'.
As shown in fig. 3 and 4, when the method is used for construction, after the pier top stone-supporting template 6 and the support preformed hole positioning pipes 7 are installed in place, the template positioning ribs 1 are spanned on the tops of two opposite stone-supporting templates 6, 4 positioning rings 5 are respectively arranged in the 4 support preformed hole positioning pipes 7, then the template positioning ribs and the tops of the templates are subjected to spot welding, the lower ends of the anchoring ribs 3 are welded with a pier top steel rib framework, and the positioning of the stone-supporting template 6 and the support preformed holes 7 is completed. When the pier top and the cushion concrete are poured, the cushion template and the support preformed hole positioning pipe cannot be displaced. The lower ends of the anchoring ribs are poured into the pier top concrete, after construction is completed, the anchoring ribs and the template positioning ribs are cut and separated, the template positioning ribs and the template are separated and then integrally taken down from the cushion stones, and the anchoring ribs are welded at the two ends of the template positioning ribs and then can be repeatedly used.
