Description

CONNECTION UNIT FOR MODULAR MEMBER AND CONSTRUCTION METHOD OF MODULAR STRUCTURE}

The present invention relates to a method for constructing a connection unit and a modular structure for a modular member, and more particularly, a connection unit and a modular unit for a modular member that can secure structural continuity between a plurality of modular members and improve coupling performance by the connecting unit. It relates to a construction method of the structure.

In the construction field, a prefabricated structure using a modular member has been in the spotlight for a drastic shortening of construction period and improvement of structure quality. The prefabricated structure is a structure type that is manufactured by dividing a large structure into unit members and then assembling it on site. Unit members, commonly called modular members, are manufactured under environmental conditions to ensure quality and workability. In addition, considering the manufacturing cost and productivity of the modular member, the transfer process of the member and the installation process in the field to have a constant size and shape.

Structural systems composed of modular members shall ensure structural continuity and sufficient connection performance of each member. When deformation and relative displacement between members occur at the connection of the modular member, smooth load transfer cannot be achieved in the whole structural system. Therefore, not only the type of modular member but also the connection method is an important requirement for the prefabricated structure to be established. Therefore, many researchers have proposed various types of modular structures and connection methods.

The method of connecting the modular members is classified into a method using post tension and a mechanical coupling method using a connecting member.

The first method is to introduce post tension using tendons that penetrate the members so that the members are joined by compressive forces.

The second method is to install the exposed rebar or coupler to function as a connecting part when manufacturing the modular member, and then connect it with the adjacent modular member in the field. At this time, there is a method of connecting the exposed reinforcing bars or connecting the reinforcing bars using a coupler, as well as using a separate connecting member made of steel.

However, the existing method needs to be improved in terms of constructability and maintenance.

In the case of the post-tension method, a separate equipment for introducing a tension force is required, and workability and workability may be deteriorated, and reinforcement details may be complicated by a separate anchorage and sheath pipe embedded. Long-term loss of tendon can be prevented after grouting to sheath pipe after introducing tension force to tendon, but it is impossible to re-tension later, requiring maintenance fixing device separately. In addition, in the case of post-tension, it may be difficult to apply to a short section as instant loss occurs.

In addition, in the case of mechanical joint method, the construction is very complicated, and since the compressive force is not introduced to the joint surface, cracking may occur very easily as the tensile force is generated at the interface during loading. Therefore, there is a risk of cracking and stepped joints during common use, and problems such as leakage and steel corrosion may occur.

In FIG. 1, a first site-pouring area A1 and a second site-pouring area A2 are provided on the upper surfaces of the first modular member PC1 and the second modular member PC2, and the first modular member PC1 is provided. Although the modular member connection unit 10 is illustrated as being embedded in the upper surface of the second modular member PC2, the arrangement of the modular member connection unit 10 is not limited thereto, and the first modular member PC1 may be disposed. And according to the arrangement of the first site-pouring area (A1) and the second site-pouring area (A2) provided in the second modular member (PC2) can be various.

In particular, referring to FIG. 2 or 3, the modular unit connection unit 10 according to an embodiment may include a joint member 100 and a deformable member 200.

The joint member 100 may be provided, for example, in a plate shape extending in one direction.

In this case, one direction may be a longitudinal direction of the joint member 100, and may be, for example, a direction extending along an inner side surface of the first site-pouring area A1 or the second site-pouring area A2. It may be arranged to extend along three inner surfaces of the site-pouring area A1 or the second site-pouring area A2.

The deforming member 200 may be connected to the joint member 100.

The deformable member 200 may be formed of a shape memory alloy (SMA), and may be deformed through a temperature change or a magnetic field change.

In particular, referring to FIG. 4, the shape memory effect refers to a phenomenon in which an alloy, which stores an arbitrary shape, is cooled and made into martensite, and then changed into a shape and heated to be made of austenite to restore its original shape.

By applying the shape memory effect, the deformation member 200 may induce a temperature change or a magnetic field change to change the shape or shrink the length, and thereby the first modular member PC1 and the second modular member PC2. Adhesion or binding force can be introduced between

In addition, a temperature change or a magnetic field change may be induced by applying heat or a magnetic field to the deforming member 200, and the first modular member PC1 and the second modular may be adjusted by adjusting a heat or magnetic field applied to the deforming member 200. It is possible to adjust the adhesive force or the bonding force introduced between the members PC2.

The deformable member 200 may be changed into a hook shape by a temperature change or a magnetic field change.

Herein, the case in which the deformable member 200 is changed to a hook shape has been described as an example, but the changed shape of the deformable member 200 is not limited thereto, and may be provided between the first modular member PC1 and the first in-site casting member. Any shape can be used as long as it is easy to form an adhesive force between the second modular member PC2 and the second in-site casting member.

Hereinafter, a case in which the deforming member 200 is changed into a hook shape will be described as an example.

In this case, a part of the deformable member 200 may be changed in shape by a temperature change or a magnetic field change, and another part of the deformable member 200 may be changed in length by a temperature change or a magnetic field change.

Referring back to FIG. 2 or 3, the deforming member 200 may include the first deforming member 210.

The first deforming member 210 may include a first deforming part 212, a second deforming part 214, and a third deforming part 216.

The first deformable portion 212 may be connected to the lower end of the joint member 100 and may be changed in shape by temperature change. For example, the first deformable portion 212 may be changed in shape in a first direction by temperature change. In detail, the first deformable portion 212 may have a first phase transformation temperature, and may be deformed in one of various directions such as a clockwise direction or a counterclockwise direction by heat applied to the first deformable portion 212.

A second deformable portion 214 may be connected to an end of the first deformable portion 212. The second deformable portion 214 may be shrunk in length by magnetic field changes. Therefore, the entire length of the first deforming member 210 may be reduced or maintained at the initial length depending on whether the second deforming part 214 is deformed.

A third deformable portion 216 is connected to an end of the second deformable portion 214, and similarly to the first deformed portion 212, the shape may change due to temperature change. For example, the third deformable portion 216 may be changed in shape in the first direction by temperature change. In detail, the third deformable portion 216 may have a first phase transformation temperature, and may be deformed in one of various directions such as a clockwise direction or a counterclockwise direction by heat applied to the third deformable portion 216.

The first deforming member 210 described above may be changed from an initial straight shape to a bent shape by, for example, a hook shape by deformation of the first deforming part 212 and the third deforming part 216. Thereafter, the contraction of the length of the second deformable portion 214 may introduce an adhesive force or a coupling force between the modular member, for example, the first modular member PC1 and the second modular member PC2 of FIG. 1.

However, in some cases, it is obvious that the initial length of the first deforming member 210 may be maintained by preventing the length of the second deforming portion 214 from contracting.

In addition, the first deformed portion 212, the second deformed portion 214, and the third deformed portion 216 may all change in shape or length by a change in temperature, and the first deformed portion 212, Both the second deformable portion 214 and the third deformable portion 216 may be changed in shape or changed in length by a magnetic field change.

Alternatively, the first deforming part 212, the second deforming part 214, and the third deforming part 216 may be configured in a different order from the joint member 100.

The deformable member 200 may be provided in plural, and the deformable member 200 may be connected to the joint member 100.

Specifically, the plurality of deforming members 200 may be spaced apart from each other along the longitudinal direction of the joint member 100.

For example, the plurality of deforming members 200 may include the second deforming member 220, the third deforming member 230, the fourth deforming member 240, and the fifth as well as the first deforming member 210 described above. It may further include a deforming member 250.

Although the plurality of deforming members 200 is illustrated as including a total of five deforming members 200 in FIG. 2, the number of deforming members 200 is not limited thereto and may be provided in various numbers greater than or less than five. Of course it is.

Hereinafter, the plurality of deforming members 200 may include the first deforming member 210, the second deforming member 220, the third deforming member 230, the fourth deforming member 240, and the fifth deforming member 250. It will be described by taking the case of including.

The second deforming member 220 may be connected to the first deforming member 210 at a lower end of the joint member 100.

The second deforming member 220 may include a fourth deforming part 222, a fifth deforming part 224, and a sixth deforming part 226.

The fourth deformable portion 222 may be changed in shape by temperature change. For example, the fourth deformable portion 222 may be changed in shape in the second direction by temperature change. In detail, the fourth deformable portion 222 may have a second phase transformation temperature, and may be deformed in one of various directions such as a clockwise direction or a counterclockwise direction by heat applied to the fourth deformable portion 222.

In this case, the second phase transformation temperature may be different from the above-described first phase transformation temperature, and the second direction may be different from the above-described first direction.

As a result, when the temperature change is induced to the plurality of deforming members 200 as a whole, the first deforming member 210 is deformed and the second deforming member 220 is not deformed, or the first deforming member 210 is not deformed. And the second deforming member 220 may be deformed.

In addition, when the shape of the first deforming member 210 is changed in the clockwise direction, the shape of the second deforming member 220 may be changed in the counterclockwise direction.

A fifth deformable portion 224 may be connected to an end of the fourth deformable portion 222. The fifth deformed portion 224 may be shrunk in length by a magnetic field change. Therefore, the entire length of the second deforming member 220 may be reduced or maintained at the initial length depending on whether the fifth deforming part 224 is deformed.

The sixth deformable part 226 is connected to an end of the fifth deformable part 224, and like the fourth deformed part 222, the shape may change due to temperature change. For example, the sixth deformable portion 226 may be changed in shape in the second direction by temperature change. In detail, the sixth deformable portion 226 may have a second phase transformation temperature, and may be deformed in one of various directions such as a clockwise direction or a counterclockwise direction by heat applied to the sixth deformable portion 226.

As described above, the second deforming member 220 may be changed from an initial straight shape to a curved shape by, for example, a hook shape by the deformation of the fourth deforming part 222 and the sixth deforming part 226. The first site-pouring member to be poured into the modular member, for example, the first site-pouring area A1 or the second site-pouring area A2 of FIG. 1, by the length contraction of the fifth deformable portion 224, and An adhesive force or a bonding force can be introduced between the second in-site casting members.

However, in some cases, it is obvious that the initial length of the second deforming member 220 may be maintained by preventing the length of the fifth deforming part 224 from contracting.

On the other hand, the third deforming member 230 may be provided in the same form as the first deforming member 210, the fourth deforming member 240 may be provided in the same form as the second deforming member 220, Since the fifth deforming member 250 may be provided in the same form as the first deforming member 210, a detailed description thereof will be omitted.

As described above, the plurality of deforming members 200 may be arranged to be symmetric about a central axis extending in a direction perpendicular to the longitudinal direction of the joint member 100, or deforming members having different phase transformation temperatures may be alternately disposed.

For example, when the plurality of deforming members 200 includes three deforming members, the first deforming member 210, the second deforming member 220, and the third deforming member 230 may be disposed in the joint member 100. Can be connected to.

Alternatively, when the plurality of deforming members 200 includes four deforming members, the joint member 100 may have the same shape as the first deforming member 210, the second deforming member 220, and the second deforming member 220. The deformable member and the deformable member provided in the same form as the first deforming member 210 may be connected in the order.

However, the arrangement of the plurality of deformable members 200 connected to the joint member 100 is not limited thereto, and may be disposed between the first modular member PC1 and the first on-site casting member or between the second modular member PC2 and the second member. Anything can be done as long as the bonding force or the attachment force can be effectively introduced between the cast in place.

In addition, although not specifically illustrated, the modular unit connection unit 10 may further include an adjusting member (not shown) connected to the deforming member 200 to adjust a heat or magnetic field applied to the deforming member 200. Can be.

For example, the adjustment member may be individually connected to the first deforming portion 212, the second deforming portion 214, and the third deforming portion 216, or may be individually connected to the plurality of deforming members 200. have.

As a result, the shape of a part of the deforming member 200 deformed by the temperature change and the other part of the deforming member 200 deformed by the magnetic field change are individually controlled, or the shapes of the plurality of deforming members 200 are individually controlled. Can be controlled.

In particular, with reference to Figures 5 (a) to (c), the behavior of the above-described modular unit connection unit 10 can be as follows.

 FIG. 5A illustrates a first phase transformation temperature T1, in which the first deforming member 210 is a PC part (for example, the first modular member PC1 or the second modular member PC2 of FIG. 1). It can be modified within.

Specifically, the shape of the first deformable portion 212 and the third deformed portion 216 is changed to, for example, a hook shape in the PC portion by the temperature change, and the length of the second deformed portion 214 is not changed. You may not.

In addition, the second deforming member 220 may be maintained in an undeformed state and is straight on the CIP part (for example, the first in-site pouring area A1 or the second in-site pouring area A1 of FIG. 1). Can be exposed in the form.

Thereby, when forming a CIP part in the 1st site pouring area | region A1 or the 2nd site pouring area | region A1, it can work easily.

FIG. 5B illustrates a second phase transformation temperature T2 state, in which the second deforming member 220 may be deformed in the CIP part.

Specifically, the shape of the fourth deformable part 222 and the sixth deformable part 226 in the CIP part is changed into a hook shape by the temperature change, and the length of the fifth deformable part 224 is not changed. Can be.

FIG. 5C shows a magnetic field applied state, and the second deformed portion 214 of the first deformable member 210 and the fifth deformed portion of the second deformed member 220 in the PC portion and the CIP portion due to the magnetic field change. The length of 224 can be shrunk.

Thus, the modular unit connection unit according to an embodiment may be embedded in the joint of the modular member to improve the adhesive force of the modular member, and the coupling force at the interface between the site casting part (CIP part) and the pre-production part (PC part). It is possible to increase, to minimize the deterioration in workability that can occur in embedding the connection unit using the shape memory alloy, and to control and recover from cracks at the interface that can occur during common use.
