Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1-4, the recyclable steel bar support for capping beam construction of pier stud of bridge engineering comprises a capping beam template 1, a steel bar 2, two steel bar supports 3 and a fixing bolt 4; the cross section of the bent cap template 1 is of a regular trapezoid structure with a wide upper part and a narrow lower part; the rod iron 2 inserts in the bent cap template 1 to the setting is at the center of bent cap template 1, set up two rows of bolt holes along the central line symmetry of rod iron 2 on the bottom plate, fixing bolt 4 inserts from the bolt hole, and the upper end offsets with rod iron 2, rock about preventing the rod iron, fixing bolt 4 dismantles or installs more easily, insert the bolt hole with fixing bolt 4 when using and play the effect of fixed rod iron 2, when needs are demolishd, can conveniently demolish fixing bolt 4. Thereby realizing the dismantling of the steel bar 2. As an optimal technical scheme, the contact position of the fixing bolt 4 and the bent cap template 1 is provided with a square gasket 7, the arrangement of the square gasket 7 can increase the stress area of the bent cap template 1, the fixing bolt 4 can be effectively prevented from slipping, and the fixing bolt 4 is prevented from loosening so as to support and stabilize the steel bar 2.
The diameter of the steel bar 2 is matched with the inner height of the bent cap template 1, the outer diameter of the steel bar 2 is in contact with the inner wall of the bent cap template 1 and is inserted into the bent cap template 1, and the outer diameter of the steel bar 2 is preferably capable of being inserted into or taken out of the bent cap template 1. The steel bar support 3 is arranged in the bent cap template 1 and supported on two sides of the steel bar 2, and the height of the steel bar support is matched with the inner height of the bent cap template 1.
