Description

Nut / connector or sleeve / connector for prefabricated unit wall products and fastener connector for assembly and fastening, RC wall construction method using the same {nut / connector, sleeve / connector and fastener connector for self-assembly, setting, fixing unit block foam. R.C wall construction method using the same component}

The present invention is a further improved invention related to the invention patent No. 10-1791545 "prefabricated unit wall for outer insulation and the outer wall construction method using the same". The "rightener connector" and the current right angle to facilitate the construction process, while prefabricating and fixing the assembled unit wall, that is, the unit block type products, which are mentioned here, in a precise and rigid manner. The addition of a nut function at both ends of the connector and also a sleeve function and a modification of part of the rim's contour, which is applied to either side of the wall product It is about omission of the use of the plate and to be the exposed concrete surface.

The "prefabricated unit wall" products in the above-mentioned inventions are invented to be applicable to RC construction method, which is a reinforced concrete construction method.

When the reinforcing bar is centered and the outer finishing plate parts with inner insulation and inner finishing plate parts are assembled in pairs between the bars on both sides to form the unit block shape of the rectangular parallelepiped, they are connected left and right It is assembled and fixed to form a structure of one building structure.

As a result of actual sample construction with these products, in order to ensure the stable and solid installation of the assembly process of the right and left assembling connection process, the unit coupling between the products itself should be solid and smooth. There was also a problem.

In addition, even in the plates constituting both sides of the unit block wall, the outer surface is integrally attached to the heat insulating material, but the inner surface is not so, it is relatively vulnerable to the flow side pressure due to the filling of concrete mortar, and also may cause a full stomach. In order to prevent this, in the present invention, in order to reinforce the bending strength of the inner plate, it is a method of attaching by tightening the anchor plate (anchor bolt) which is a separate back-up panel (back-up panel) embedded in the insulation.

As a result of conducting this method, it was confirmed that this method adds another step of attaching and assembling the plate, and also confirmed that the anchoring force of the anchor bolt, which is important for the firmness of the insulation material, is not stable.

In particular, since the rectangular inner plate does not allow the inside space of the unit product, which is a rectangular parallelepiped, to be installed in the confined space where the rebar is placed, it is necessary to install the auxiliary process (wiring, piping, terminal embedding, anchor bolt fitting, etc.). Another problem was that the work efficiency was not as smooth as expected. In addition, depending on the material properties of the finished plate, the curing drying process after the filling of cement mortar is relatively longer.

The present invention has been made to solve the problems as described above, the object is as follows.

First, it is possible to assemble and combine internal and external plate parts for prefabricated unit walls without using adhesives or temporary tools, and also to fix them firmly in the construction process of connecting them to each other at the construction site. To provide a way to do that,

Second, the current right angle connector, which joins the inner side edge of the unit wall product, is improved and complemented by a new one (or both) right angle nut / connector. In this case, the inner side finishing plate composition is omitted. However, the product must also have a formwork function, so the flexural strength is guaranteed right in place of the finishing plate, and the plywood is temporarily attached with bolts / nuts, assembled and fixed, and after filling with mortar, it is disassembled and used repeatedly. It is intended to be finished with mortar cotton.

third. An additional complement to the right angle connector, which allows precise insertion of the sleeve and spacer components into the right angle connector, allows both sides of the wall to be exposed concrete. It would be a cheap and robust construction for partition walls for internal space partitions, or for building externally interrupted walls.

Fourth, the prerequisite for formwork is that it must have sufficient durability to ensure safety against the fluid lateral pressure generated when concrete is filled. In this product, for this purpose, attach 2 ~ 3 anchor nuts of appropriate size to the center part of the inner surface of the outer surface finishing plate, and come out to the surface of the insulation material with another anchor bolt / nut connected to this anchor nut. It is to assemble the wall frame by inserting a computer bolt nut so that it can be penetrated into the center of the plywood, which is an inner finishing form plate. In this way, in order to prevent the hungry phenomenon in the side pressure generated by the concrete filling and to ensure the safety and to ensure the smoothness of the exposed concrete surface. ,

Fifth, if a unit frame is constructed by connecting and assembling the unit wall from side to side using a right angle nut / connector, since one or both sides are open, wiring, piping, terminal installation, etc. to be embedded inside the wall It is intended to facilitate the construction of preliminary laying of various subsidiary process and follow-up measures necessary for additional strengthening of lateral pressure strength of finished plate.

Sixth, unskilled workers can be easily familiarized with the assembly construction process.

Technical configuration of the present invention devised to solve the above technical problem is as follows.

In the "borders" that make up the rectangular "frame" that makes the outer and inner finishing surfaces of the unit wall products, there is an improvement in the correction change in which holes are placed at both ends of the horizontal rim concave grooves. In the present invention, the "fastener connector" mentioned in the present invention is inserted into the fastener connector, so as to enable the connection fixing function so that the product itself has a coupling function.

Rectangle has been modified to add a nut function to one (or both) edge extensions of a rectangular connector that allows the two "frames" rectangular edges to be connected and assembled at right corners of the four "4" corners. I want to solve it with nuts / connectors.

In this case, the surface on which the nut function is applied is omitted from the finish component plate, and the edge of this part should be improved and improved to the "a" shape from the current shape.

Two concave grooves are extruded at the edges of the two contours mentioned here. One is vertically in the same direction with respect to the sheet surface, and the other is opened in a right angle (90 degree) direction.

First of all, the correction change of the concave groove opened in the vertical direction will be explained. When the rectangular wall unit wall product is placed on the floor of the construction site, a fixed position 20 to 30 mm from both ends of the upper and lower edges positioned in the horizontal direction will be described. Pre-machining is carried out so that a hole punched with a groove width of about 30 to 35 mm is drilled at an inner position of the groove, and the recessed groove opened at right angles has a locking jaw shape and an opening function inside the recessed groove. Further, the nut right-angle connector component having a connection function to have a rectangular unit wall block by fitting into the concave groove has a protruding fitting injection shape suitable for engaging this locking jaw.

According to the present invention, the following effects are expected.

First, when the four corners of the outer surface finishing plate border and the inner surface border of the rectangular parallelepiped unit wall block product are fastened by assembling assembly, the unit wall block product of the precise and solid rectangular parallelepiped shape is assembled without the adhesive by the locking jaw coupling effect. Is fixed.

Second, in case of assembling and combining the above products from side to side, up and down, insert fastener-type connection clamp like a clamp into a hole already drilled in the rim, so it is precise and robust without using adhesive. Assembly can be fixed. ,

Third, it is possible to omit the finishing plate for the inner surface configuration by modifying the current right angle connector to a right angle nut / connector. Instead, the Tego plywood, which has sufficient resistance to lateral pressure, can be used repeatedly as a formwork finish substitute and can be handled to reduce costs and greatly simplify the structure assembly process.

Fourth, the side pressure increases with the wall thickness. Attach the appropriate size anchor bolts / nuts to the inner surface of the outer surface of the finish plate and then face the insulation surface. In addition, the threaded bolt nut is used to secure sufficient strength strength against the side pressure, and the anchor bolt function is also used to hold the external finish plate as it is buried in concrete.

Fifth, the rib / connector enables the construction of exposed concrete walls among the internal partition walls that divide the interior space of the building at the same time as the external partition walls.

Sixth, with simple prior knowledge, unskilled workers have no difficulty in performing assembly work and there is no waste generated by using adhesives.

In other words, when the heat dissipation system is applied, it has a function of the jaw rest where the insulation is placed.

FIG. 14 is a perspective view illustrating an open unit block product assembly that is assembled to an “open frame” made of the “a” frame of FIG. 6 and a right angle sleeve connector of FIG. 13 so that both surfaces may be finished with an exposed concrete surface.

This unit block product is a formwork "frame" combined product that is assembled by connecting the four (4) corners of the rectangular "a" frame frame, which divides the inner and outer surfaces, with the sleeve connector of Fig. 9. The thickness of the concrete wall that is filled in the interior space of this product is various, including 100,125,150,175,200mm.

Existing invention is the outer part of the prefabricated unit wall product that also has the formwork to fill the cement concrete (reconcrete) and the outer surface finishing plate and the inner surface finishing plate is paired with each other while centering the reinforcing bar in the construction site When assembled to face each other, connected to the four corners of the rectangular concave grooves (101) of the rectangular rim (100) that is integrally attached to the four sides of the two closing plate connected to the joint position rectangular connector 200 is inserted into a rectangular parallelepiped In this case, the adhesive use process is inevitable in order to prevent the assembled or detached parts from coming off or peeling.

However, in the present invention, the inner shape of the concave groove 101 of the rim is omitted in order to omit such an adhesive use process, and the fitting convex portion 201 of the right-angle connector 200 which is a mating partner thereof is fitted. Improvement to the part 202 was to significantly strengthen the product self-assembly bonding force.

In addition, the omission of the finishing plate, which was also attached to the inner surface side, so that the surface here is exposed concrete surface. In this way, the process (electrical, electronics, communication piping, wiring, etc.) that must be installed in the interior space of the wall is provided with retrospective efficiency, and the effect of significantly shortening the curing time of the wall can be reliably expected. .

To this end, the current "-" shaped rim outline attached to the side of the inner finishing plate should be modified and improved to a "a" shape, and the tego plywood may be assembled and fixed to the unit block finishing plate. Modified and improved to have a nut function.

In order to use the unit walls (U) products assembled and assembled in this way to construct the desired building structure, the construction process is based on the step-by-step assembly construction.

To explain this again, the assembled unit wall (U) product also combines the formwork that can hold concrete mortar. Concrete mortar filling is possible only up to the horizontal height of the vessel (form) to withstand its pressure. Therefore, the construction of the intended building structure should be a construction method that considers the physical surface horizontality of the mortar of the plastered state and the side pressure due to the flow load. It must be. In the step-by-step construction, the assembly of unit wall products is possible only in the horizontal direction. Accordingly, the next step in the construction process from the foundation stage to the last stage is to fill the concrete mortar with the completed connection assembly on the left and right side, and after curing for about one night, it is repeatedly repeated on top of the charged structure. Refers to the process of assembling the connection to make the structure. This is because the cured concrete mortar cured overnight will be sufficient to support the fluid load and lateral pressure due to the plaster mortar in the next step. In order to shorten the curing time, mortar incorporating a crude agent may be used.

The left and right connection assembly of the above-mentioned unit wall products must also be firmly and precisely connected to each other to form the structure as well as to support the formwork. For this purpose, it was inevitable to use adhesives at joints between products.

In the present invention, by inserting the coupling ring 300 of Figure 3 into the hole in the edge perforation 105 of Figure 1 in this case, it is possible to combine more robust and precise assembly than the use of adhesive without adhesive.

When explaining in more detail the function of each part of the shape of the connecting ring clamp 300, 305 and 306 parts are inserted into the vertical horizontal two-way groove 102 on the edge 100 of each product around the cross-crossing part As it fits, the inner and outer surfaces of the four (4) products are connected to each other and assembled by connecting them to the left and right. Also, the 306, 302, 302, 303 and 304 triangular fitting wing portions on the left and right sides of the 306 portions are fitted into the holes 105 drilled at a predetermined position in the horizontal and horizontal grooves 102 of the edge 100 near each product edge. It is a shape of a wedge-shaped fastener for. The perforation hole is located from the centerline of the 305 to the center of the triangular faucet, and the triangular base length (30-35mm) and the linkage clamp (400) material width width (2-2.5mm) of this reference point The hole 105 is drilled.

When the triangular fitting hooks (301, 302, 303, 304) of the connecting ring clamp (300) is inserted into the hole (105) above, the sides of the products are pulled together by sliding the plug along the inclined plane of the triangle. At the same time, the lower edge of the product to be assembled on the triangular wing shape groove (307) in the bottom groove (307) of both ends of the rim hole 105 as a hook, and at the same time the assembly step can be easily inserted. It is designed to allow four (4) corner ends of different products to be fixed at one point while also providing an assembly function.

As above, even if the unit block products are connected to the left and right, assembling, fixing, and fixing the desired structure in each step, the inner surface is opened. In this open condition, when all the subsidiary processes to be embedded in the wall are finished, it should be covered with formwork. In order to reinforce the lateral pressure strength strength of the sheet, the anchor bolt nut is attached to the outer surface finishing plate as shown in Fig. 10, and the structure skeleton is performed by performing the finishing process as shown in Fig. 12 using a nut in a right angle nut connector. The structure “frame” according to the invention for completion is completed.
