Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cartridge for securing fixing elements.

Anchor bolts and the like are fixed in blind holes as anchors for attaching equipment to concrete bodies, etc., or as foundation bolts for structures. Typical examples include machine installation anchors, structural reinforcement anchors, ceiling/wall support anchors, and lock bolts.

Conventionally, methods for fixing anchor bolts using self-pseudo-binding materials (consisting of two components, a main agent and a hardening agent, hereinafter referred to as binders) have been methods that use binder cartridges (hereinafter referred to as cartridge type). (hereinafter referred to as "anchor"), and one in which a pre-mixed fluid containing the main binder and hardening agent is injected into the blank hole (hereinafter referred to as "anchor").
An injection-type anchor) is known. For example, those using mortar, epoxy, unsaturated polyester resin, etc. These methods are satisfactory in most cases, but due to their construction method, cartridge-type anchors are characterized by a bonding reaction that occurs by crushing and mixing two-component cartridges in a blind hole, and they are fixed by electricity. It is necessary to rotate the anchor bolt into the blank hole using a rotating machine such as a drill. Injection-type anchors are characterized by stirring and mixing the two components of the composite outside the hole and injecting the mixed fluid into the blank hole using an injection machine, which allows for a longer pot life until injection. After injection, it takes a considerable amount of time for the composite to harden. (Generally, 1
Therefore, a construction method that is easy to construct and cures quickly has been desired.

An object of the present invention is to provide a cartridge for fixing fixing elements that is easy to install and can be fixed in a short time. The cartridge for fixing the fixing element of the present invention is comprised of a plastic thin film tube containing the main component inside and housed in a sleeve formed of a porous or permeable member and provided with a curing agent component. This is a cartridge for fixing fixing elements.

When the fixing element fixing cartridge of the present invention is used for construction, the main agent, curing agent, and sleeve are integrated, so that they can be combined in the next step when fixing the fixing element.
1. Prepare the cartridge of the present invention. 2. Insert the cartridge of this invention into the blind hole. 3. Press and insert bolts, etc. Bonding can be achieved through the above three steps. Conventionally, on the other hand, 1. Prepare a main ingredient. 2. Prepare the hardening agent. 3. Prepare the sleeve. 4. Insert the sleeve into the blind hole. 5. Mix the base resin and curing agent. 6.Put this mixture into the blind hole. 7. Press and insert bolts, etc. The above seven steps were required. Since the cartridge of the present invention requires only three steps, construction is very simple, and the labor and time required for the work can be reduced.

The binding material used in the present invention may be one with well-known technology, but the binding material consists of two components: a liquid (base agent) and a solid (curing agent), and the liquid component has a low viscosity of 50 poise or less. However, it is desirable. for example,
Examples include unsaturated polyester resin as a liquid component and benzoyl peroxide as a solid component.

Due to its handling, it is preferable that the component that adheres to the sleeve of the binding material be a solid component. Dissolve it in a solvent and adsorb it onto the sleeve. Alternatively, a mixture with adhesive is applied to the sleeve.

One of the components that is not attached to the binder sleeve is a liquid, and the component can be inserted into the blank hole by inserting a container filled with fluid in advance, or by directly injecting the fluid without filling the container. However, in order to maintain a constant blending ratio of the components attached to the sleeve, it is desirable to use a container.

In the present invention, the main ingredient is housed in a plastic thin-film tube container, and the plastic thin-film tube is manufactured by a conventional method from olefin resin such as polyethylene or polypropylene, or synthetic resin such as polyester resin or nylon. used.

The sleeve used in the present invention is made of woven fabric or non-woven fabric, such as glass fiber,
Preferably, it is made of chemical fiber, paper, metal, etc., or a porous plastic molded product, a porous inorganic fired product, etc.

Most preferably, the sleeve is porous and permeable, so that the pressure of the bolt insertion allows the fluid of the bonding material to be distributed through the sleeve and throughout the hole gap, so that the pressure of the bolt insertion allows the fluid of the bonding material to be distributed through the sleeve and into the gap between the holes. It is capable of adhering the necessary amount of the ingredients sufficiently.

It is preferable that the length of the sleeve be approximately the same as the depth of the blind hole, the outer diameter of which is less than the diameter of the blind hole, and the inner diameter of which is greater than or equal to the diameter of the bolt. It is fixed to the side of the hole and integrates the bolt and blind hole. The bolts may be wood screws, plastic bolts, or steel bolts, but steel screw bolts or deformed steel bars are most preferred.

The blind hole is preferably cylindrical, and the hole diameter is preferably 5 m/m or less than the maximum diameter of the bolt.

Next, the cartridge for fixing the fixing element of the present invention will be explained with reference to illustrated embodiments. Note that this is an example and the present invention is not limited to this. FIG. 1 is a central vertical sectional side view of a cartridge for fixing fixing elements of the present invention, and FIGS. 2 and 3 are central vertical sectional side views showing the construction method. 1 is a sleeve to which a hardening agent is attached, 2 is a plastic thin film tube, 3 is a base material, 4 is a closed ring, 5 is a bolt, 6 is a combination of the base material and hardener, 7 is a base, and 8 is an insertion hole.

Next, a specific example will be given and explained.

This is an example of embedding a threaded bolt with a diameter of 16 mm into a blank hole in concrete with a compressive strength of 240 Kg/cm ² . The insertion hole dimensions are 19 mm in diameter and 150 mm in length. The sleeve is made of glass cloth (18 stitches/dimension) and has a thickness of 0.5
It has a cylindrical shape with an inner diameter of 16.2 mm, an outer diameter of 17.2 mm, and a total length of 150 mm, with the implanted tip closed. 2 g of 50% diluted benzoyl peroxide was evenly applied to the sleeve. The sleeve contains 15 c.c. of unsaturated polyester resin in a plastic membrane tube.

In construction, as shown in FIG. 2, first the cartridge for fixing the fixing element of the present invention is inserted into the insertion hole 8 of the concrete base 7, and then the bolt is inserted by manual pressure. Insertion is continued until the result is as shown in FIG. Two hours later, the bolt was firmly attached to the base, and when I tried to force it out, the bolt broke outside the hole.

As described above, the cartridge for fixing the fixing element according to the present invention has various effects such as fixing the fixing element very easily and quickly, and the present invention has a wide range of applications.
