The invention relates to a parallel rod anchoring device and a method for a flexible sheet material such as cloth, paper, film and leather, in particular to an anchoring device for anchoring and stretching various fiber sheets on civil engineering structural members such as buildings and bridges. The flexible material comprises a material which is softened and deformable under specific conditions such as high temperature, and the sheet material may be formed by laminating. technical background

A flexible sheet material such as cloth, paper, or film may be adhered to a solid surface with an adhesive such as glue. If the flexible sheet material can meet after bypassing the solid, it can also be bonded together with the adhesive at the meeting place (such as the end of the sheet) or stitched together with a thread (rope), at this time pulling the flexible sheet The body of the material, the flexible sheet material will abut against the solids being bypassed. If the sticking or stitching fails for some reason (such as aging debonding, pulling very tight, etc.), the flexible sheet material may fall off the solid it bypasses. However, if it is not necessary to attach or sew, the flexible sheet material can be clamped on the solid to be wound when being pulled, and the tension is tightened. This will not only eliminate the above-mentioned combination for fixing the flexible sheet material. Later, it can also bring convenience to practical applications.

The technical solutions and working processes of the present invention are further described below with reference to the accompanying drawings, but the scope of the present invention is not limited thereto.

In the present invention, the number of the parallel bars may be two or two or more. The outer section of the rod section is not necessarily circular, but preferably it is not angular. The shape and thickness of each rod may be different. Parallel parts It is used to keep the rods parallel to each other with a gap. At least one parallel connection. The parallel pieces are not necessarily regular bars. The rod and the parallel member may be integrally formed by a connection such as casting, welding, bonding or perforation. When the perforation is connected, a penetrating hole is provided in the parallel member for the parallel rod to penetrate. If necessary, the rods can be made in multiple segments. In order to anchor the flexible sheet material self-locking in the parallel rod to an external object such as a structural member, an anchor hole may be provided on the parallel member for auxiliary anchors such as rivets, bolts, screws, booms, and tie rods (or simply Inserting through; a protruding portion for piercing anchoring may be provided on the parallel member or the rod member, the protruding portion being an overhanging portion of the rod member after passing through the rod hole, or a side extension portion on the parallel member, Auxiliary anchors for inserting holes such as joints.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view of an embodiment of the present invention, since there are only two bars and are shaped like parallel bars, which may be called a parallel bar anchor or a II anchor. Hereinafter, a method of applying self-locking anchoring to a flexible sheet using such a device will be described with reference to Figs.

After the flexible sheet material is passed around one rod, it will meet (Fig. 7). The flexible sheet material that will be closed by one hand will be pinched together near the end of the sheet, and the other bar will be anchored with the other hand. The whole is rotated a certain angle toward the sheet in the direction of the rod (Fig. 8 is the case after turning 180°, and the anchor can also be rotated but the sheet is reversely rotated). At this time, if the anchor is fixed, and the flexible sheet material is pulled, the sheet is pulled. The material will be tightened more tightly in the parallel rods, that is, by self-locking by tightening around the rods. In other words, the parallel rods in the parallel bar anchors thus achieve clamping of the ends of the sheets, or mechanical Wrap around.

The other end of the flexible sheet material can be treated in the same direction in the opposite direction. The parallel bar anchors at both ends of the holding sheet are pulled by force, and the sheets are self-locking in the parallel bars. If the parallel bar anchor is fixed to an external object in some way (such as in a pre-drilled hole in the anchor hole of the parallel member through the insert into the corresponding position of the structural member), the sheet is also anchored to the external object. It is. Obviously, the process is convenient and fast, and the effect is firm and reliable.

Embodiment 1: As shown in Fig. 1, two parallel bars are integrally combined with the bar parallel members (which can be completed by casting), and each of the parallel members is provided with two anchor holes for the anchor members to pass through.

Embodiment 2: As shown in FIG. 2, two parallel rods are inserted into a strip-shaped parallel member (assembled and assembled) provided with a rod hole, wherein one rod member passes through a protruding portion other than the parallel member for inserting a joint, etc. Auxiliary anchor with holes.

Embodiment 3: As shown in Fig. 3, two parallel rod members are inserted into a strip-shaped parallel member (assembled and assembled) provided with a rod hole, and three parallel members divide each rod member into two segments, and each of the parallel members is provided with 1 anchoring hole for the anchoring member to pass through.

Embodiment 4: As shown in Fig. 4, two parallel rod members are inserted into the side plate type parallel members (assembled and assembled) provided with the rod hole, and each of the parallel members is provided with two anchor holes for the anchor members to pass through. Embodiment 5: As shown in Fig. 5, two parallel rods are connected together at a certain distance along the length by integral casting (such as casting) or splicing, bonding, etc., wherein one rod is anchored at the joint portion. A hole for the anchoring member to pass through.

Embodiment 6: As shown in Fig. 6a, five parallel rods are integrally combined with the parallel parts, and the parallel parts are combined in the form of strips and sheets, and each of the parallel parts is provided with one anchor hole for the joint (or other anchor rod) Piece) Wear the rod and anchor the rod member from the joint hole.

Figure 6 (b) shows the inlay strip matched with the example 6 of the flexible sheet material parallel rod anchoring device. The three inlay strips have been connected by the side panels as a whole, and the side panels connected to the inlay strips are provided. An anchoring hole for the joint (or other anchoring member) to be worn, and then the rod is anchored from the joint hole.

Figure 6 (c) is an example of a flexible sheet-like material parallel rod anchoring device 6 and its associated inlay strip assembly is shown as a whole.

The above flexible sheet material may be one layer or may be laminated by multiple layers in an initial state.

When anchoring holes are provided on the parallel parts or rods, the number of anchoring holes is arbitrary, depending on site conditions and force requirements.

When the fibrous sheet is structurally reinforced, the surface of the member and the fibrous sheet may be coated with an adhesive prior to anchoring the fibrous sheet to the member to obtain a chemically bonded anchor. Of course, this chemical bonding can only serve as an aid, because the mechanical winding can transmit force separately before the adhesive cures, and the adhesive can effectively resist peeling after being dried, even if it is degummed due to overload, high temperature or aging. As a result of bonding failure, unbonded fiber sheets can still rely on mechanical anchoring to function. Since peeling or debonding is no longer an issue, the reinforcement efficiency of high performance fiber materials can be greatly improved.

Depending on the clamping mechanism, this new type of anchor can also be referred to as a wrap-around anchor, or simply a wrap.

It should also be noted that when a prestressed fiber sheet is used for structural reinforcement, the new anchor can be used as its fixed end anchor, and Embodiment 6 can be used as its tension end anchor. The matching inlay strip of the embodiment 6 is used for prestressing the fiber sheet by inserting the anchored fiber sheet into the sheet (or groove) of the parallel piece by using the inserting strip to make it Parallel bars are parallel and the bead (or block) is anchored. When there are a plurality of inlay bars, as needed, the inlay bars can be integrated by the cover plate, the side plates, the side bars, and the like.

The invention can also be used to advertise a slogan, a fence for isolation enclosures, a grip or anchor for a curtain, and the like.

The above are only some of the embodiments of the present invention. According to the above concept of the present invention, the application can also make various modifications and changes thereto, such as the number, length, section, sectional shape and Dimensions (not required for each piece), and the style, shape and size of the parallels can be adjusted to accommodate changes in field conditions such as force magnitude and application conditions. However, such modifications and variations are within the spirit of the invention.
