Description

Middle wall structure and construction method to enhance the stability of middle wall structure {WALL STRUCTURE ENHANCED REINFORCING STABILITY OF SANDWICH CONCRETE WALL, AND METHOD FOR CONSTRUCTING THEREOF}

The present invention relates to a structure and a construction method of a middle heat wall in which the outer wall and the inner wall are divided by a heat insulating material, and more specifically, the outer wall, the inner wall and the heat insulating material of the middle heat wall are matched integrally and a thermal bridge between the outer wall and the inner wall is established. Preventing the construction process also relates to a simple heat-resistant wall structure and construction method that enhances the stability of the heat-resistant wall structure.

The wall structure of the heat insulating function is largely divided into an inner heat insulating wall structure having an insulating material on an inner surface of a wall and a beam (hereinafter referred to as a'wall'), and an outer heat insulating wall structure having an insulating material on an outer surface of the wall.

First, in the heat-insulating wall structure, since the heat-insulating material is located on the indoor side of the wall (hereinafter referred to as the'wall inner surface'), the influence of the cooled wall on the room temperature is small, and the inside surface of the wall is relatively quickly at room temperature due to the small heat capacity of the heat-insulating material. It has the advantage of letting you reach. However, in the heat-insulating wall structure, condensation can easily occur on the wall itself because the temperature difference between the inner surface of the wall and the outdoor side of the wall (hereinafter referred to as the'outer wall') is relatively large, and mold may form on the wall due to the condensation. And it had the disadvantage of weakening the strength of the wall concrete. Moreover, the heat-insulating wall structure, when a fire occurs, can easily transfer flames to the insulation material placed on the inside surface of the wall, and as the insulation burns, harmful fumes and toxic gases are introduced into the room in a large amount, which is disadvantageous to residents who are evacuated.

On the other hand, the outer insulating wall structure, because the insulating material is located on the outer surface of the wall, the inner surface of the wall is insulated, so it has excellent energy efficiency compared to the inner insulating structure, and has the advantage of reducing the amount of condensation and mold on the wall. However, as the insulating material was exposed to the outside, the durability of the outer wall of the wall was weak, and there was a disadvantage in that installation of a blank for external work such as wall finishing and additional construction of a protective finish were inevitable. Moreover, when a fire occurs, a large amount of fumes and toxic gases from the combustion of the insulation are released to the outside, and there is a risk of adversely affecting not only the firefighters extinguishing the fire, but also nearby pedestrians.

However, the internal and external insulation wall structures and the external and thermal insulation wall structures have different structural advantages and disadvantages of the internal and external insulation wall structures due to mutually different structural differences, thereby complementing the disadvantages of the internal and external insulation wall structures. There was a limit that I could not.

In order to minimize the structural limitations of the inner and outer insulating wall structures, a technique related to the middle heat barrier structure was developed.

In the conventional middle heat structure, since the insulating material is located between the walls, the disadvantages of the inner insulating wall and the outer insulating wall can be solved.

However, in the wall of the conventional medium heat structure, since the outer wall and the inner wall are separated from each other with respect to the heat insulating material, strength and rigidity of the wall itself cannot be achieved, and the strength and rigidity have to be reduced compared to the inner and outer heat insulating wall structures. Moreover, in the process of constructing the wall, after pouring the insulation material in advance, the concrete for building the outer and inner walls is poured, so the insulation material that forms the interrupted heat cannot be maintained due to the pressure exerted by the concrete being poured or pierced or repositioned. There was a problem of departure.

In addition, in order for the heat insulating material constituting the middle heat structure to maintain a constant distance between the outer wall surface and the inner wall surface, the outer wall formwork and the inner wall formwork must be formed at regular intervals. To this end, in the conventional middle heat structure, the outer wall formwork and the inner wall formwork are fastened to each other using materials such as spacers and connection seams, and a heat insulating material is fixedly arranged between the outer wall formwork and the inner wall formwork via the spacer and the connection seam. By the way, since the spacers and the connection seams are penetrated through the heat insulating materials arranged in this way, the insulation function of the perforated heat insulation is inevitably weakened. In particular, since the spacers and the connection seams through the heat insulation materials are steels having high thermal conductivity, The thermal bridge phenomenon between the outer wall and the inner wall was deepened through the connection seam.

In addition, in the case of the conventional middle heat wall, the above-mentioned heat bridge phenomenon should be minimized, so the middle heat wall structure has a limitation in applying means for connecting the outer wall and the inner wall despite the structure having the outer wall and the inner wall divided by the insulation. there was. Therefore, the durability between the outer wall and the inner wall of the middle heat-insulating wall structure was relatively lower than that of the inner heat-insulating wall structure and the outer heat-insulating wall structure.

After all, although the conventional middle heat wall structure consumes a relatively large amount of time and cost for construction, existing problems of the outer heat insulating wall structure and the inner heat insulating wall structure, as well as between the outer and inner walls of the conventional middle heat wall structure, The problem of thermal bridge and weakening of integrity could not be solved.

In the middle heat wall structure 10, the heat insulating material 13 is disposed between the walls, and is divided into an outer wall 11 and an inner wall 12 with the insulating material 13 as a boundary. In addition, the outer wall 11 and the inner wall 12 and the insulating material 13 are mutually fastened through the construction material 100 to form a complete middle heat barrier structure 10.

However, since the construction material 100 is formed of an insulating material to prevent thermal bridges of the intermediate heat wall structure, there is a limit to firmly supporting the outer wall 11, the inner wall 12, and the insulating material 13 integrally. Therefore, the supporter 200 of this embodiment is configured to complement the construction material 100, so that the outer wall 11, the inner wall 12, and the heat insulating material 13 are mutually matched to form an integral body.

To this end, the supporter 200 of the present embodiment includes: a first shear connecting material 210 through which the heat insulating materials 13 are horizontally penetrated, and both ends are respectively installed on the outer wall 11 concrete wall and the inner wall 12 concrete wall; A second shear connecting material that penetrates the insulating material 13 in the diagonal direction, and both ends are respectively provided on the outer wall 11 concrete wall and the inner wall 12 concrete wall, and one end is connected to one end of the first shear connector 210. 220);

In this embodiment, when the outer wall 11 or the inner wall 12 loses the fixation and applies pressure in the vertical direction by gravity, the second shear connector 220 primarily supports the pressure, and the first shear connector 210 ) Switches the direction of the pressure and supports it horizontally with a compressive force. That is, the horizontally arranged first shear connecting member 210 converts the pressure in the vertical direction applied by the outer wall 11 or the inner wall 12 to the horizontal direction, thereby making the outer wall 11 and the heat insulating material 13 and the inner wall 12 It is to increase the stress on the liver to form a solid wall structure.

In addition, since the supporter 200 is installed so as to surround and pass through the reinforcing bars 41, 41', and 42 installed in the wall structure, the supporters 200 are bound to the reinforcing bars 41, 41', 42 forming the skeleton of the wall structure. Therefore, the durability and stability of the wall structure composed of the outer wall 11, the insulating material 13, and the inner wall 12 are enhanced.

More detailed description of the supporter 200 of the present invention will be described below.

2 is a cross-sectional view schematically showing another embodiment of a longitudinal cross-sectional view of a middle heat barrier structure according to the present invention, and FIG. 3 schematically shows a mechanical support state of a supporter for construction of a middle heat barrier structure according to the present invention It is one drawing.

The building is composed of a wall 31, a slab 32, and a beam 33, as shown in FIG. 2, and an empty floor 34 such as an entrance or a balcony may be formed on the lower floor of the beam 33. In addition, the walls 31, slabs 32, and beams 33 are provided with reinforcing bars 41, 41', 42, 43 in various reinforcement forms for their own rigidity.

Here, the wall 31 is made of the wall structure 10 of the present embodiment, and the wall structure 10 is provided with a bracket-shaped supporter 200 to integrally form the outer wall 11 and the inner wall 12 and the heat insulating material 13 Increase your sex.

The supporter 200 of the present embodiment includes: a first shear connecting member 210 through which the both ends are respectively provided on the outer wall 11 and the inner wall 12 of the concrete wall through the heat insulating material 13; Through the heat insulating material 13 in a direction crossing the first shear connecting material 210, both ends are respectively provided on the outer wall 11 and the inner wall 12 of the concrete wall, and one end is one end of the first shear connecting material 210. It is composed of; a second shear connecting member 220 that is connected to.

The first shear connecting material 210 penetrates the heat insulating material 13 so as to be vertically arranged in the vertical direction of gravity, and both ends are connected to the outer wall 11 and the inner wall 12, respectively. Therefore, the first shear connecting material 210 integrally connects the outer wall 11 and the inner wall 12.

On the other hand, the second shear connecting member 220 penetrates the heat insulating material 13 so as to be inclined in the vertical direction of gravity, so that both ends are connected to the outer wall 11 and the inner wall 12, respectively. Therefore, the second shear connecting member 220 is integrally connected such that the outer wall 11 supports the inner wall 12.

Through this connection structure, the wall structure 10 complements the binding force of the insufficient spacers 110 and 110' for binding between the outer wall 11 and the inner wall 12. In this embodiment, the connection between the first shear connecting member 210 and the second shear connecting member 220 is made on the outer wall 11, and the end is made on the inner wall 12, which is the arrangement of the supporter 200 on the outer wall ( 11) and the inner wall 12 are not limited. Therefore, in the following claims, the arrangement of the supporter 200 is described as the outer wall 11 and the inner wall 12. It is significant that the structure in which the outer wall 11 and the inner wall 12 are replaced with each other by equality is included in this right. .

For reference, as shown in FIG. 3, when gravity is applied to the outer wall 11, the second shear connector 220 inclined acts downward, and the first shear connector 210 acts as an inner wall 12 The compressive force (C) acts in the direction. That is, in the supporter 200 of the present embodiment, the gravity of the outer wall 11 is firstly applied to the second shear connector 220, and the first shear connector 220 is distributed to the first shear connector 210 by compression force. Thus, the gravity of the outer wall 11 is diverted and converted in the direction of the heat insulating material 13 and the inner wall 12 of the first shear connecting material 210.

After all, the diagonally arranged first shear connecting member 210 and the horizontally disposed second shear connecting member 220 are integral with each other, and both ends are fastened to the outer wall 11 and the inner wall 12, respectively, so the outer wall 11 Alternatively, the supporter 200 may convert the pressure of the wall to the gravity applied from the inner wall 12, and through this, the interrupted heat wall in which the supporter 200 is buried has an effect of increasing its own stress.

The arrangement method of the supporter 200 of the present invention having the above-mentioned advantages, when the lower floor of the beam 33 is an open doorway or a floor 34 such as a balcony that cannot directly support the beam 33, the beam Since the supporter 200 converts the sedimentation force generated from the outer wall of (33) to a horizontal pressure to increase the stress of the beam (33) itself, it can increase the stability and integrity of the structure and complete the solid wall structure (10). To make.

The supporter 200 of the present embodiment can be built into the wall 31 of the building as well as the beam 33 as shown in FIG. 2, and in particular, the beam 33 made of an empty layer 34 on the lower floor is due to the loss of the support base. It is preferable that the supporter 200 is provided to reinforce the weakened rigidity. To this end, the supporter 200 is installed as described above to connect the outer wall 11 and the inner wall 12 located in the beam 33, through which the outer wall 11 and the inner wall 12 are strengthened by solidity to support You will have

In addition, the supporter 200 of the present embodiment is installed to pass through the reinforcing bars 42 installed on the wall 31. To this end, the connection portion between the first shear connecting member 210 and the second shear connecting member 220 of the supporter 200 surrounds the reinforcing bar 42, so that the supporter 200 is hung and supported by the reinforcing bar 42 Achieves. As a result, the supporter 200 is secured in the fixation, through which the binding force between the outer wall 11 and the inner wall 12 is strengthened.

4 is an exploded view showing an embodiment of the components of the supporter.

The supporter 200 of the present embodiment further includes coating members 230 and 230' covering one or more selected from the other end of the first shear connecting member 210 and the other end of the second shear connecting member.

Since the wall structure 10 of the present embodiment should be prevented from thermal bridges, direct connection between the outer wall 11 and the inner wall 12 through the medium should be minimized. However, the supporter 200 reinforced for integrity between the outer wall 11 and the inner wall 12 and the heat insulating material 13 is made of a metal material having high thermal conductivity to ensure its own rigidity. Therefore, a thermal bridge is generated between the outer wall 11 and the inner wall 12 via the supporter 11.

In order to solve this problem, the supporter 200 of the present embodiment covers one or more selected from the first shear connecting member 210 and the second shear connecting member 220 so as not to contact the inner wall 12, and is utilized for the covering. It is preferable that the coating material is a synthetic resin material having excellent thermal insulation properties. To this end, in the present embodiment, the first shear connecting member 210 and the second shear connecting member 220 that directly contact the inner wall 12 are coated members 230 and 230', respectively. The covering members 230 and 230' may be formed in a tube shape so as to directly cover the first and second shear connecting materials 210 and 220, and become independent members connected to the first and second shear connecting materials 210 and 220. Instead of the first and second shear connecting materials 210 and 220, the other end contacting the inner wall 12 may be achieved.

In addition, the supporter 200 of the present embodiment forms a connection structure in which one end of the first shear connecting member 210 and one end of the second shear connecting member 220 are separable.

The first shear connecting material 210 is installed in a horizontal posture in the wall structure 10, the second shear connecting material 220 is installed in an inclined posture in the wall structure 10, and the first shear connecting material 210 Since the second shear connecting material forms a structure connected to each other, it is not an easy process in the working process to install the first and second shear connecting materials 210 and 220 through the insulating material 13. Therefore, by separating the first shear connecting material 210 and the second shear connecting material 220, the first shear connecting material 210 or the second shear connecting material 220 is installed first, and the remaining one is installed later, but later installed The shear connector is to be positioned in accordance with the position of the shear connector already installed, and the first and second shear connectors 210 and 220 are connected to each other.

To this end, each end of the first shear connector 210 and the second shear connector 220 of this embodiment is formed with threads 211 and 221, and the threads 211 and second shear of the first shear connector 210 The threads 221 of the connecting material 220 are bound to each other via the both end nuts 250.

Subsequently, in the supporter 200 of the present embodiment, the flanges 240 and 240' are connected to at least one selected from the other end of the first shear connecting member 210 and the other end of the second shear connecting member 220.

The supporter 200 buried in the concrete should be in close bond with the concrete. To this end, the supporter 200 may be formed with a myriad of irregularities on the outer surface, such as a reinforcing bar. In particular, the first and second shear connecting materials 210 and 220 are connected to each other to form an integral end (first and second) of the supporter 200. Flanges 240 and 240' may be connected to function as anchors on the inner wall 12 of the other end of the shear connector.

The flanges 240 and 240' of this embodiment form a wider cross-section than the cross-sections of the first and second shear connecting materials 210 and 220 so that relatively wide protrusions are formed as shown in FIG. 4, particularly at the ends of the supporter 200. Since it is installed, the supporter 200 maintains its position and stably binds the outer wall 11 and the inner wall 12. Threads 212 and 222 are formed at the other ends of the first shear connecting member 210 and the second shear connecting member 220, and the flanges 240 and 240' are formed with nut grooves (not shown), thereby (212, 222) and the flanges (240, 240') are bolted.

For reference, the first and second shear connecting members 210 and 210' are connected to each other to form a structure surrounding a part of the outer wall 11 and the other end to the inner wall 12 by flanges 240 and 240'. Since it forms a hanging structure, the binding force between the supporter 200 and the outer wall 11 and the inner wall 12 is further increased, thereby enhancing the integrity of the outer wall 11 and the inner wall 12 and the heat insulating material 13.

5 is a cross-sectional view sequentially showing the installation of the supporter in the wall construction method according to the present invention.

The installation process of the supporter 200 will be sequentially described with reference to the above-described embodiment.

When the heat insulating material 13 and the reinforcing bars 41, 41', and 42 are reinforced for the construction of the wall structure 10 as shown in FIG. 5(a), the heat insulating material 13 is applied to the first shear connecting material 210 at the design point. Penetrate horizontally.

When the installation of the first shear connecting member 210 is completed, as shown in FIG. 5(b), both end nuts 250 are installed on the thread 211 at one end of the first shear connecting member 210.

Subsequently, as shown in FIG. 5(c), the second shear connecting member 220 is penetrated through the heat insulating material 13 so as to cross the first shear connecting member 210. Therefore, the second shear connecting member 220 is disposed obliquely, and the threads 221 of one end of the second shear connecting member 220 are inserted into the both end nuts 250 and tightened. As a result, one end of the first shear connecting member and the second shear connecting member 220 are integrally connected via both end nuts 250. In this embodiment, the connecting portion between the first and second shear connecting materials 210 and 220 is wrapped around the reinforcing bar 42, so that the fixing force of the first and second shear connecting materials 210 and 220 is strengthened.

When the installation and connection of the first and second shear connecting materials 210 and 220 are completed, the flanges 240 and 240' are connected to the other ends of the first and second shear connecting materials 210 and 220. Since the threads 212 and 222 are formed at the other ends of the first and second shear connecting materials 210 and 220 exposed on the inner wall 12, the flanges 240 and 240' are bolted to the threads 212 and 222, , Through this, the other ends of the first and second shear connecting materials 210 and 220' are covered by the flanges 240 and 240', and are tightly bound to the inner wall 12.
