Abstract
The invention discloses a backing plate used for anchor rod pull-out test. The backing plate is made of plastic cement materials, and is a rectangular structure provided with four identical end brackets; each end bracket is provided with an anchor-fixing though-hole, and the four anchor-fixing though-holes are all provided with internal screw threads; four anchor-fixing bolts are connected with the internal screw threads of the four anchor-fixing though-holes; the center part of the backing plate is provided with a pull-out though-hole; and reinforcing ribs are arranged between each anchor-fixing through-hole and the pull-out through-hole so as to increase the strength of the backing plate. The backing plate used for anchor rod pull-out test is simple in structure, and is capable of shortening the time and reducing the cost of the anchor rod pull-out test, and performing the anchor rod pull-out test on anchor rods with short reserved rod parts. Complete detecting data can be obtained, better monitoring is performed on engineering quality, jerry-build can be prevented effectively, and engineering quality and work efficiency are improved.
Description
Technical field
The present invention relates to a kind of anchor pole drawing backing plate.
Background technology
In the existing anchor pole pull-out test, generally all be by randomness desired anchor pole to be detected, usually the ratio that extracts is 1%, but because the part that anchor pole is reserved outside is different in size, some anchor pole reserved part is shorter, anchor pole is not carried out pull-out test, and the data of providing during therefore to detection are inaccurate, engineering caused seriously influence.The pull-out test fundamental purpose of anchor pole is exactly the quality that ensures engineering, prevents jerry phenomenon, detects the effect that anchor pole plays in engineering simultaneously, and underproof anchor pole has this very big hidden danger to construction quality.But present drawing mode does not have good method to test to the relatively shorter anchor pole of reserved part, therefore has very big leak.
Summary of the invention
Purpose of the present invention just provides a kind of simple in structure, can reduce the anchor pole drawing backing plate of anchor pole pull-out test time and cost.
Anchor pole drawing backing plate of the present invention, made by plastic material, backing plate is the rectangular structure with four same side pin, all have tapped anchoring through hole on each end pin, anchor bolt is connected with the anchoring through hole whorl, the backing plate center arranges the drawing through hole, is equipped with reinforcement between four anchoring through holes and the drawing through hole to increase backing plate intensity.
Anchor pole drawing backing plate of the present invention, in the anchor pole pull-out test, according to test objective, tested anchor pole passes with the hollow lifting jack from the drawing through hole and is connected by overlapping other reinforcing bars, tested anchor pole and lifting jack inner casing is fixed together, and installing displacement measuring equipment and instrument, regulate four anchor bolts on the end pin, make backing plate be in best angle, be beneficial to measure, pressurize to carry out pull-out test by manual oil pressure pump.
Anchor pole draw pad plate structure of the present invention is simple, can reduce anchor pole pull-out test time and cost, also can test the anchor pole that reserved part is relatively shorter, can obtain complete detection data, and the quality of engineering better monitored, can also prevent effectively that jerry situation from taking place, and improves construction quality and work efficiency.

Embodiment
A kind of anchor pole drawing backing plate, made by plastic material, backing plate 1 is the rectangular structure with four same side pin, all have tapped anchoring through hole 3 on each end pin, anchor bolt 4 is threaded with anchoring through hole 3, backing plate 1 center arranges between 2, four anchoring through holes 3 of drawing through hole and the drawing through hole 2 and is equipped with reinforcement.Anchor bolt 4 adopts the bolt of gear type with better stressed.When anchor pole drawing backing plate used, drawing through hole 2 was enclosed within on the tested anchor pole 5.
Claims (1)
