Description

Length adjustable connector for two parallel insulation panel, and the insulation panel block using the same}

The present invention relates to a connector for fixedly connecting two insulation panel walls that serve as formwork for concrete walls by facing each other, more specifically, in order to integrally install the insulation panel wall on the concrete wall wall of the building, When the concrete wall and the insulation panel wall are installed at the same time by installing concrete between the two insulation panel walls after installing the panel walls spaced apart upright, the two insulation panel walls facing each other in the state composed of a plurality of insulation panels are concrete. In order to serve as a formwork for the casting and curing of the present invention, and to connect the two insulating panels facing each other, the length of the connector is adjustable so that the gap between the two insulating panels changes according to the thickness of the concrete wall and the insulating block using the same .

Today's general buildings are made of reinforced concrete structures, which begin with the installation of concrete walls and slab construction formwork. After installing the ceiling slab construction plate horizontally on the ground at the top of the, it is generally constructed by filling and curing concrete on the inside of the frame and the upper surface of the plate.

In this case, the 'frame' called 'formwork' is made by connecting a plurality of formwork panels, which are rectangular plate-shaped plate.

In other words, the construction of walls and slabs begins with the installation of formwork as a form with an internal space that can be filled with concrete by connecting multiple formwork panels.

The wall as described above, install the formwork by arranging and connecting a plurality of formwork panels so that each front side facing each other in the state in which the reinforcing bar is installed on the site where the wall is erected by the thickness of the wall around the reinforcement, Constructed by curing the concrete between the two formwork, the wall is completed by dismantling formwork adhered to both sides of the wall after the concrete has been dissolved.

However, in the case of the concrete wall is constructed as described above, the heat insulation is poor, in particular, if the construction of the building's outer wall only concrete walls will increase the cost of heating and cooling bar, such as the outer wall wall is required to be constructed with concrete In the case of providing heat insulation to concrete walls, after curing the concrete walls to dismantle the formwork, a large number of insulation panels are closely installed on the wall of the cured concrete walls to complete the insulation panel walls, and the exterior surface of the insulation panel walls The finish will be finished.

However, as described above, the method of installing the insulation panel wall on the wall after constructing the concrete wall first is not only cumbersome but also causes a long construction period. In recent years, the insulation panel wall is not installed without installing the formwork for the concrete wall. In some cases, the insulation panel wall and the concrete wall are used together.

When the insulation panel wall and the concrete wall are integrally formed as described above, since the insulation panel wall plays a role as a formwork, it is not necessary to install a conventional formwork for constructing the concrete wall, thereby simplifying the construction and shortening the construction period. .

In addition, in winter, since the insulation panel wall, which serves as a formwork, minimizes the temperature drop of the curing concrete wall, there is no need to use a separate insulation for preventing condensation of the concrete wall during curing.

However, in order to install the insulation panel wall and the concrete wall together, like a formwork, first, a pair of insulation panel walls should be installed to face each other in a spaced apart state at regular intervals, and thus face the two insulation panel walls. In order to install so that the metal plate-shaped connector is used, look at this as follows.

As shown in FIG. 1, a pair of insulation panel walls that serve as formwork for constructing a concrete wall of the insulation panel wall includes a plurality of insulation panels 11 each made of insulation such as styrofoam and urethane foam. As a structure connected on the same plane, the two insulation panels 11 are fixedly coupled by a plurality of connectors (12).

At this time, the conventional connector 12 is a plate, as shown in Figure 2, the central piece 12A constant width; An extension piece 12B extended at both ends of the center piece 12A in a state in which it is gradually expanded than the center piece 12A; A plurality of bridges 12C extending at the ends of the extension pieces 12B; An embedment piece 12D coupled to bendable at the end of the bridge 12C; It is made of a back.

A plurality of "c" shaped holes H are formed between the end of the extension piece 12B and the inner end of the bridge 12C and the embedding piece 12D.

In the conventional connector as described above, the buried piece 12D is bent at right angles to the bridge 12C, and the bent buried piece 12D is embedded in the insulating panel 11 to become an insulating block. By connecting a large number of insulating blocks to the top, bottom, left and right, the insulation panel wall is formed. The conventional connector is a simple plate shape and the rigidity is reduced, so that when the external force acts in the direction perpendicular to the plane of the connector, the insulation panel wall is not fixed. There is a difficulty in precise construction because it can move easily.

In addition, since reinforcing bars and connectors are not coupled or connected to reinforce the concrete wall, the spacing of the two insulating panels 11 facing each other is narrow as the deformation of the connection part is caused by the collision with the concrete when the concrete is placed. Losing may result.

And it is preferable that each of the embedded pieces 12D embedded in the insulation panel 11 be alternately bent to both sides as necessary, but the entire embedded piece 12D provided in the conventional connector can only be bent to one side. There is no structure.

In addition, each of the embedded pieces 12D provided in the conventional connector is a structure in which the whole is bent together in the same direction, the length of material extending from the bridge 12C is longer than necessary, the material cost required for making the connector Will increase.

In addition, since the conventional connector is made to have a specific length can not be used in the concrete wall with different thickness, there is a problem that the connector must be manufactured for each type of thickness of the concrete wall.

In other words, the conventional connector has a lack of compatibility, the inventory burden is increased, thereby increasing the manufacturing cost.

The present invention was devised to solve all the problems of the conventional connector for connecting a pair of insulating panels facing each other, the rigidity is improved, the two insulating panels are stably fixed, the interior of the concrete wall is installed upright It is an object of the present invention to provide a heat insulating panel connector that can be prevented when the concrete is placed by combining with the reinforcement, and an insulating block that can be easily constructed using the heat insulating panel wall using the same.

In addition, the manufacturing cost is reduced by reducing the length of the insertion piece of the connector to be insulated into the insulation panel, but by providing a connector that can freely change the bending state of the plurality of pieces as necessary by forming a plurality of each bend independently independent. There is another object of the present invention.

In addition, by adjusting the length according to the thickness of the concrete wall, there is another object of the present invention to increase the compatibility of the connector to reduce the inventory cost.

The above object of the present invention, the bent portion formed along the longitudinal direction in the width direction central portion of the connector, the concave-convex portion formed in a line along the edge of the connector and the reinforcing bar pieces protruding in the widthwise end of the connector, and the end portion in the bridge It is achieved by a plurality of embedded pieces to be combined, and the overlapping connecting pieces that correspond to the center piece of the conventional connector but are separated into two and overlapped.

In the connector of the present invention, the two insulation panels facing each other are stably fixed to each other because the rigidity is increased by the bent portion and the linear concave-convex portion, and the deformation resistance to external force acting perpendicular to the plane of the connecting portion is significantly improved. Since it is coupled to the reinforcing bar, it prevents deformation during concrete placing, and thus, there is an advantage that accurate wall construction is possible.

In addition, by reducing the length of the buried piece extending from the bridge can not only reduce the material cost required for making the connector, but also has the advantage that each piece can be bent independently as needed.

In addition, since the length of the entire connector can be adjusted by changing the overlap length of the overlapping connecting piece, it can be used regardless of the thickness of the concrete wall, thereby minimizing the inventory holding cost of the connector.

 In addition, the insulating block coupled to the connector of the present invention has the advantage that the construction time can be shortened by facilitating the installation of the insulating panel wall.

The present invention, when constructing a wall in which the insulation panel wall is integrally bonded to the wall of the concrete wall, in order to allow a pair of insulation panel walls facing each other can be used as the formwork for concrete wall construction, both ends are each other It relates to a connector and a heat insulating block using the same to serve to secure the two heat insulation panels in the spaced apart state by embedding in two opposing heat insulation panels.

Insulation panel connector can be adjusted in length of the present invention, the bent portion and the concave-convex portion is formed to improve the rigidity, the reinforcing bar is provided for the coupling with the reinforcing bar, the entire body is not made of a single body is approximately symmetrical shape similar in shape Its characteristic is the structure composed of two bodies in shape.

As described above, the connector of the present invention has a structure in which a bent portion is formed over the entire length along the longitudinal direction at the central portion in the width direction, and an uneven portion is provided at the edge portion except for both ends in the longitudinal direction, thereby increasing rigidity and increasing deformation resistance. to be.

At this time, the concave-convex portion is linear, and is a structure recessed from one side of the connection portion to the opposite side, and on one side becomes a recess like groove, and on the opposite side is a protrusion.

The plate-shaped connector of the present invention is composed of a pair of connector members separated from each other, each connector member includes an overlapping connecting piece; An extension piece extending from one end of the overlapping connecting piece; A plurality of bridges extending at the ends of the extension piece; A plurality of embedding pieces extending toward the extension piece between two adjacent bridges in a state where the outer end is coupled to the end of each bridge; It is made of a back.

As described above, the connector of the present invention becomes one connector by overlapping coupling portions of two connector members overlapped, and the length of the entire connector can be changed by adjusting the overlapping length of the two overlapping connectors.

In addition, the outer end of the buried piece is connected to the bridge end of each connector member, that is, the buried piece does not extend outward along the longitudinal direction of the bridge, thereby minimizing the amount of material required for making the connector, and each buried piece is bent independently. There is another feature of the invention in one structure that can be bent in different directions.

Details of the effects and the resulting effects, including the object and technical configuration of the present invention will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention.

Figure 3 is a perspective view of the combination of the invention one embodiment adjustable length insulation panel connector, Figure 4 is an exploded perspective view, Figure 5 is an exploded front view.

Prior to description, in order to avoid confusion along the direction, the "up and down direction" is referred to as "width direction" and the "left and right direction" as "length direction".

As shown, the connector of the present invention,

Separately manufactured and composed of a pair of connector member 300 capable of overlapping coupling, each connector member 300,

A plate-like overlapping connecting piece 31 in which a bent portion B is formed along the longitudinal direction at the center in the width direction;

Extending toward the outer side in the longitudinal direction from one longitudinal end of the overlapping connecting piece 31, the width gradually increases as the distance away from the overlapping connecting piece 31, the bent portion (B) of the overlapping connecting piece 31 is extended An extension piece 32;

A plurality of bridges 33 extending outwardly in the longitudinal direction at the longitudinal ends of the extension pieces 32;

The widthwise both sides of the outer end of each of the plurality of bridges 33 adjacent to each other in the longitudinal direction of the bridge 33 are coupled so that they can be bent, and the inner end positioned between the two bridges 33 is an extension piece 32. A plurality of embedding pieces 34 extending toward the end side of; And the like.

In addition, the pair of connector members 300 are coupled to each overlapping connecting piece 31 so that each embedded piece 34 is located in the opposite direction, and the overlapping length of the two overlapping connecting pieces 31 is overlapped. By adjusting the length of the entire connector can be changed.

At this time, the pair of connector members 300, the respective overlapping connecting pieces 31 are coupled in a way that overlaps, it may be fixed by welding two overlapping overlapping connecting pieces 31 of the adjusted state to the appropriate length. .

Alternatively, a plurality of coupling holes (not shown) penetrate at regular intervals along the longitudinal direction in one side of the overlapping connecting piece 31, and coupling protrusions (through drawings in the other overlapping connecting piece 31) may be penetrated through the coupling holes. There is no particular limitation on the method of joining the two members such that the two members may be joined by a method of penetrating the coupling protrusion through the joining hole after forming the protrusion).

The overlapping connecting piece 31 and the extension piece 32 may be divided into upper and lower portions with respect to the bent portion B, respectively, the upper and lower portions of the overlapping connecting piece 31 and the overlapping connecting piece 31 and 31. The lower part and the bent part B have a shape of "a" or "b" on the side view, and the upper and lower portions of the overlapping connecting piece 31 are in parallel with each other, which is the case of the expanding piece 32. The same is true.

And between the expansion piece 32, the bridge 33 and the buried piece 34 is formed with a "H" shaped through hole (H), the buried piece 34 in a direction substantially perpendicular to the longitudinal direction of the connector The bar is embedded in the heat insulation panel in a bent state, and when the buried piece 34 is bent, the through hole H is changed from a "c" shape to a substantially rectangular shape.

However, when the inner end of the embedment piece 34 and both ends in the width direction contact the end of the extension piece 32 and the bridge 33, respectively, the embedment piece 34 is not bent. Instead of the through-hole H of the shape may appear in the form of a "c" shaped incision.

In addition, the extension piece 32 has a triangular (or wedge-shaped) shape as a whole, and the width thereof gradually expands away from the overlapping connecting piece 31, but any geometric shape having a wider width than the overlapping connecting piece 31 is irrelevant. .

That is, the extension piece 32 only needs to be wider than the overlapping connection piece 31 so that the embedment piece 34 connected to the bridge 33 extending from the extension piece 32 can be sufficiently embedded in the insulation panel. .

Of course, as shown in FIG. 6, the overlapping connecting piece 31 is expanded to the expanding piece 32 to form a coalescing overlapping connecting piece 31 ′ in which the central piece 31 and the expanding piece 32 are coalesced, and coalesced. The bridge 33 may be extended to one end portion in the longitudinal direction of the intermediate connection piece 31 ′.

However, in the above case, the manufacturing cost of the connector is increased, except in the case where the high rigidity of the connector is particularly required, the union overlapping connection piece 31 within a range capable of maintaining rigidity for fixedly connecting the insulation panel. ') Into the overlapping connecting piece 31 and the expanding piece 32, and to reduce the width of the overlapping connecting piece 31 as much as possible, while at the same time increasing the width of the extension piece 32 to increase the number of buried pieces 34. Reasonable.

The connector of the present invention as described above is embedded in the concrete wall, the bar is reinforced in the concrete wall bar, in order to connect the connector with the reinforcing bar so that the connector can be stably positioned without deformation during concrete placement, approximately rectangular It is preferable to protrude and extend one or more reinforcing bar pieces 31A on at least one side of both widthwise ends of the overlapping connecting piece 31 having a shape similar to that of bendable.

That is, as shown in FIG. 7, the reinforcing bar 31A may be bent in a direction substantially perpendicular to the plane of the overlapping connecting piece 31 to connect with the reinforcing bar S installed upright.

When the reinforcing bar coupling member 31A is bent and connected to the reinforcing bars S as described above, in some cases, the bar reinforcing bar coupling members 31A provided in each of the overlapping connecting pieces of the two connector members may overlap each other. Some of the engaging pieces 31A may not be used.

In addition, the bridge 33 'of the center portion of the plurality of bridges 33 is relatively wider than other bridges, which is to extend the bent portion B to the bridge 33' of the center portion. to be.

The bent portion (B) is to increase the rigidity of the connector, in particular to improve the deformation resistance in the direction perpendicular to the plane of the connector, in order to further increase the deformation resistance, the overlapping connecting piece 31 and the expansion piece 32 It is also preferable to form a linear concave-convex portion (B ′) which is recessed from one side to the opposite side along the edge of and forms a linear recess on one side and a linear protrusion on the opposite side.

At this time, the two entanglement connecting pieces 31 of the two members overlapping each other overlap the bent portion B, so that the concave and convex portions B 'also overlap with each other, such as one concave and convex portion, so that the two members can be in close contact with each other. do.

In addition, the bridge 33 in which the bend portion B is not formed has a relatively narrow width, and thus has low deformation resistance, and thus, the uneven portion may be formed in the center portion in the width direction of the bridge 33 except for the bridge 33 'in the center portion. B ') is extended, and the uneven portion B' is also formed in the portion of the expansion piece 32 partitioned by the uneven portion B 'and each of the embedding pieces 34, and is caught in the reinforcing bar in the bent state. Forming the uneven portion B 'also in the reinforcing bar 31A is good for improving the rigidity of the connector.

The connector of the present invention configured as described above is a plate-like structure made of a metal material such as steel plate, bar binding force may be insufficient due to the bent portion (B) and the uneven portion (B ') and through holes (H) Although the bonding force with the concrete may be improved, it is more preferable to form the through hole H1 in the bent portion B of the expanded piece 32 and the central bridge 33 ', which are wider than the overlapping connecting piece 31. desirable.

That is, through the through-hole (H1) and the concrete on both sides of the expansion piece 32 and the center bridge 33 'is connected to each other, the connector can be stably located inside the concrete wall.

And the connector of the present invention is embedded in the concrete wall, it is preferable to make the connector as a plated metal plate in order to prevent the surface rust of the connector by moisture during concrete curing.

By embedding the both ends of the buried piece 34 of the connector of the present invention as described above, the heat insulating panel facing each other, the insulating block of the present invention is made bar, the buried piece 34 of the connector member 300 overlaps the connecting piece ( 31) or in a state of bending at a right angle with the coalescing overlapping connecting piece 31 ', as shown in FIG. 8, by injecting the insulating panel 500 into the embedding piece 34 so that the embedding piece 34 is embedded, The insulating block 600 is to be made.

In addition, by overlapping the connection piece 31 or the combined overlapping connection piece 31 'by combining the two connector member 300 into one connector 400, the pair of partial insulating blocks 600 is one unit insulating block 700 It is made of), by arranging a plurality of such unit insulating block 700 in an up, down, left, right arrangement, the insulation panel wall that can be used as the formwork for concrete wall construction.

At this time, a plurality of coupling protrusions (not shown) are protruded on the upper surface of the heat insulation panel 500, and a coupling groove (not shown) is formed on the bottom surface of each of the coupling protrusions on the upper surface of the heat insulation panel. On the opposite surface, a plurality of vertical unevenness (not shown in the drawing) is formed along the horizontal direction in order to improve the bonding force with the concrete wall, such that the upper surface, the bottom surface, the opposite surface and the side of the insulation panel 500 are insulated. Means for coupling between panels or with concrete walls can be provided in various forms.
