Screw piece for insulation of concrete wall construction {SCREW PIECE FOR INSULATING MATERIAL CONSTRUCTION}

The present invention relates to a screw piece for the construction of the insulation of the concrete wall used to attach the insulation and the finishing material to the concrete wall, and more particularly, while forming the screw thread of the screw piece in a double structure of the main thread and the auxiliary thread, By making the diameter according to the outer diameter of the auxiliary thread smaller, it is not only simple and easy to fasten when constructing, but also provides a double fastening force after construction, so that the concrete wall insulation material can be improved significantly. Relates to a screw piece.

In general, it is inevitable to construct various types of finishing materials for various purposes such as insulation, soundproofing, and waterproofing on the walls of various buildings that are poured with concrete, and the construction method of such insulating materials and finishing materials is conventional. Edo is proposed and widely used in various ways.

Among them, the construction method of the conventional heat insulating material and the finishing material, which is the most widely used construction, is described as an example in FIG. 1 of the accompanying drawings.

That is, the heat insulating material (2) made of a material such as styrofoam is attached to the wall surface (1) of the concrete building using an adhesive (B), and the surface of the heat insulating material (2), wood, metal, After the connecting member 3 made of a material such as synthetic resin is installed at predetermined intervals, the finishing material 4, which is also plate-shaped, made of gypsum board or the like, is attached to each other by using fixing means such as nails, screws, or taka. It is.

However, in the construction method as described above, in order to construct the finishing material 4 on the surface of the heat insulator 2, the construction of the connecting member 3 must be inevitably preceded, which not only takes a lot of work time but also makes the work difficult and difficult. In addition, there was a problem that workability is significantly reduced, such as high skilled workers are required to adjust the vertical and horizontal.

In addition, in recent years, a new type of construction method as shown in FIG. 2 has been proposed to somewhat compensate for the above problems.

This is applied to each surface of the concrete wall surface 1 and the heat insulating material (2) in contact with the adhesive (B), and the sand (6) is sprinkled with a predetermined thickness thereon, and the adhesive (B) again on the surface of each sand layer ) And the thermal insulation material 2 was fixed to the wall surface 1 by the method of mutual bonding of the sand layers on which the adhesive agent B was sprayed, and then the surface of the insulation material 2 was finished using double-sided tapes 5. (4) was finally fixed.

However, the method of fixing the heat insulating material (2) and the finishing material (4) as described above may use the sand (6), the effect of the heat insulation may be good, but compared to the former has a problem that the adhesive strength is lowered, and also the sand Since the particle size should be uniform, there was a difficulty in supplying the sand, which also required more work time.

In addition, another form of construction method has been proposed to supplement the above problems, which is attached to the finishing material (4) on the surface of the heat insulating material (2), the connection member 3 or both sides as described above It is a structure which fixes the finishing material 4 directly to the heat insulating material 2 using a separate screw piece, without using the tape 5 etc.

This construction method has also been proposed by the applicant of the present application and has been filed as a patent, but this has a problem that the fixing force is not good due to the structural problem of the screw piece can be easily released or detached, moreover, the heat insulating material 2 has a structure Due to its weak strength in general, the general screw piece of a simple form has a limit in fundamentally eliminating the above problems.

The present invention has been invented to solve the various problems as described above, the purpose of the construction is to use a screw piece having a screw thread of the dual structure of different diameters of the screw thread when constructing the insulation and the finishing material on the concrete wall surface The construction provides a screw piece for the construction of the insulation material for the concrete wall surface to improve the fastening force due to the double structure of the thread after the construction, as well as to improve the workability, such as easy and easy operation.

The present invention for achieving the above object is achieved by providing a screw piece of an improved form,

The screw piece for the insulation construction of the concrete wall surface according to the present invention comprises a conical head formed with a tool fastening groove of the "+" type or "-" shape in the center of the upper surface, and vertically circularly below the head of the conical head And a main structure and a secondary thread having different diameters of the screw threads on the outer circumferential edge of the shaft.

In particular, the threads are formed in a dual structure with different diameters, but the thickness of the auxiliary thread is formed smaller than the main thread while forming the thickness as thin as possible, easy to fasten but doublely coupled after fastening the fastening force It is characterized by a significant improvement.

The present invention as described above can be installed more simply and easily by using a screw piece having a double structure in the construction of the heat insulating material and the finishing material on the concrete wall surface of various buildings, as well as shorten the work time, reduce construction costs Will have the effect.

In addition, since the screw thread of the screw piece has a thin plate-like dual structure, it provides a double coupling force after construction, thereby maintaining a firm fastening force, thereby improving safety.

Therefore, these effects will have the effect of doubling the various functions such as insulation, soundproofing and waterproofing with a firm fastening force of the insulation and finish.

Detailed structure and action for the implementation of the present invention will be described in detail by the accompanying drawings as follows.

First, the heat insulating material 20 is fixed to a corresponding surface of the concrete wall surface 10 of various buildings, and a specific method thereof includes a roller having a protrusion formed on one side (the surface attached to the wall surface 10) of the heat insulating material 20. The surface roughness, that is, the rough surface 21 is formed by rolling by using a not shown.

One side of the heat insulating material 20 having the rough surface 21 is formed with a plurality of recessed grooves 22 filled with an adhesive at equal intervals.

The reason for forming the rough surface 21 on one side of the heat insulating material 20 is to improve the adhesive force of the adhesive (B) described below, the reason for forming the recess groove 22 is the adhesive (B) It is to increase the adhesive strength by filling.

The concave groove 22 is processed by a cutter, etc., the depth and width are each 2 ~ 4mm, the shape is sufficient to be cylindrical or triangular or more polygons, the spacing of the concave groove 22 is preferably 30 to 40mm. .

When the rough surface 21 and the recessed grooves 22 are formed on one side of the heat insulator 20, the adhesive B is applied to all or a part of the rough surface 21 or filled into the recessed grooves 22. It is glued to the corresponding surface of the concrete wall surface 10.

When the heat insulating material 20 is adhered to the concrete wall surface 10 as described above, the solid adhesive is formed by the adhesive filled in the recess 22 and the adhesive applied to the rough surface 21.

Thereafter, the finish 30 is superposed on the other surface of the heat insulating material 20, and the fastening material 30 is fastened to the heat insulating material 20 using a plurality of screw pieces 40.
