JPS61130521A - Anchor head - Google Patents

Abstract

PURPOSE:To regulate the head of an anchor in conformity with the conditions of construction site by a method in which a hole for tension member and a coupler are provided for the anchor plate, and an adjust plate with a hole for tension member and a clamp metal are also provided to the plate. CONSTITUTION:A tension member hole 21 and an injection hole 12 are drilled in an anchor plate 1. A tension member hole 21 is also drilled in the center of an adjust plate 2, whose one side is of a tapered groove pitch 23. The adjust plate 2 is lapped on the plate 1 and coupled with a coupler 13, and a tension member is passed through the center of a tube 71 and regulated to keep it almost vertical. The tension member can thus be tensed at the center of the anchor hole and the tube 71, and its angle can be easily adjusted without the needs to slide the adjusting plates.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anchor head, and more particularly to an anchor head provided for transmitting force from a man to a tension a without principle.

Generally, the tensile material is drilled into the structure to transmit the tensile laying force to the tensile material and also to distribute the concentrated force of the anchor! In order to do this, the force from the so-called relic must be matched to the direction in which the anchor is set, but in reality, it is not possible to do so due to the current conditions. It's not easy.

Conventionally, an anchor head is composed of a pedestal, an anchor plate, and a tension member fastening fitting, and the pedestal is made of raised lumber and brackets or concrete to match the M-strip body at the site.

In the present invention, the anchor plate and adjustment plate, which are standardized in advance during construction, are made convex and grooved to ensure W during construction. I! An object of the present invention is to provide an anchor VGi& in which an anchor plate, an adjustment plate, and a tension material tightening fitting can be adjusted according to the situation.

Although the present invention will be explained in detail according to four aspects, the present invention is not limited to these drawings.

l is the anchor plate, and the through hole/l
and cement milk injection a/2 are penetrated, respectively, and the figure shows the locking part that locks on the hole wall of the anchor hole.
f13, and the fixing f@M material/Hiroshi of the adjustment plate protrudes from the other surfaces. The locking member 13 has a circular shape similar to the tensile member through hole, and has a top piece that is aligned with the anchor hole and projects perpendicularly to the plate surface.

2 is an adjustment plate, which is located at the center.

Around it there is t! i1 part or notch part 22 is provided,
It is adapted to engage with the fixed layer member /4 of the anchor plate /.

The function and usage of the present invention will be described.

! After washing, insert the anchor constant body 61 and abut the anchor plate l against the pressure receiving plate 7, and at the same time, press the hole retaining plate c1.
Pass the α side of 7 through the hanging member through hole //, place the adjust pre-cover hole on top of it, and make sure that the tensile material ≦ passes through the center of 7 and the adjust Against the top surface of plate λ! 5 Adjust f7 so that it is vertical. Then inject grout,
After reducing the proof stress to mV, tension U3 is tightened with a jack and the tension member 6 is fixed to the α load (pressure receiving G) 7 using a fitting tool such as a nut or wedge.

According to the present invention, in the case of inclined fixation, by using an adjustment plate without using a pedestal, the #J structure fixing surface and the anchor axis direction can be easily aligned, and the anchor hole and maintenance A tensioning member can be placed in the hole pipe and tensioned. Since there is a locking M version, it is easy to lock the anchor plate to the anchor hole or hole maintenance director and install it in a structure (pressure receiving V). Since the adjustment plate is rotated, the adjustment plates do not slide against each other, and the angle adjustment is performed with ease.
