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.

The first fixing member 100 and the second fixing member 200 described above may be provided in the same shape, for example, and have the in-site casting area A1 and the second modular provided in the first modular member M1. It may be arranged to be symmetrical with each other in the in-site casting area A2 provided in the member M2.

Accordingly, the first fixing member 100 and the second fixing member 200 are embedded in the pour material during the joining process between the members after the first modular member M1 and the second modular member M2 are installed in the field. The load integrally integrated with the modular member M1 and the second modular member M2 and transmitted through the tension member 300 may be transmitted to the first modular member M1 and the second modular member M2.

The tension member 300 may be formed of, for example, a shape memory alloy (SMA).

In particular, referring to FIG. 3, 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.

In addition, since the tension member 300 changes state at a specific temperature, the tension member 300 may contract the length of the tension member 300 using the tension member 300.

By applying heat or electricity to the tension member 300 by the shape memory effect of FIG. 3, when the length of the tension member 300 shrinks, a attraction force is formed between the first fixing member 100 and the second fixing member 200. Can be operated.

At this time, the attraction force applied between the first fixing member 100 and the second fixing member 200 is a tension force induced by the tension member 300, and the tension force is the first modular member M1 and the second modular member ( A compressive force can be introduced at the interface of M2).

In particular, since the tension member 300 is embedded by the pour material placed in the field-pouring area A1 provided in the first modular member M1 and the field-pouring area A2 provided in the second modular member M2. In this case, the compressive force may be directly applied to the pour material.

The compressive force introduced by the tension member 300 may be determined by the following equation.

At this time, P is a compressive force introduced by the tension member 300,

l is the initial length of the tension member 300,

Δ l is an amount of change in the length of the tension member 300,

E is the elastic modulus of the tension member 300,

A is the cross-sectional area of the tension member 300.

Through the above equation, it can be seen that the ratio of the compression force introduced by the tension member 300 and the length change amount with respect to the initial length of the tension member 300 is proportional.

Through this, the compression force introduced by the tension member 300 may be calculated by measuring the amount of change in the length of the tension member 300.

Alternatively, when a loss of tension occurs in the tension member 300 or when a compressive force is to be introduced to the interface between the first modular member M1 and the second modular member M2, the compressive force to be introduced by the tension member 300 may be removed. By calculating the amount of change in the length of the tension member 300 inversely, it is possible to adjust the heat or electricity to be applied to the tension member 300.

At this time, when the data on the change in the length of the tension member 300 according to the heat or electricity applied to the tension member 300, the data on the compression force according to the change in the length of the tension member 300 is obtained in advance, the tension member ( It is possible to more effectively control the compression force to be introduced by the 300).

In particular, referring to FIGS. 4A and 4B, when the tension force F1 is induced by applying heat to the tension member 300, the left side of the first plate 102 of the first fixing member 100 is left. Direction resistance R1 is applied in the direction, the reinforcement resistance (not shown) is applied to the reinforcement bar B in the left direction, and the pressure resistance resistance in the right direction to the third plate 202 of the second fixing member 200. Not shown) and the reinforcing bar (R) may be applied to the reinforcing bar (R2) in the right direction. The dowel resistor R3 may be applied to the through hole 106 provided in the second plate 104 and the through hole 206 provided in the fourth plate 204.

As described above, the tension force by the tension member 300 is applied to the first modular member M1 and the second modular member M2 through the reinforcing bars B as well as the first fixing member 100 and the second fixing member 200. It can be delivered in various ways.

On the other hand, the temperature control member 400 may be connected to the tension member 300 in order to control the heat or electricity applied to the tension member 300.

The temperature control member 400 may be provided in plurality, one of the plurality of temperature control member 400 is connected to one end of the tension member 300, the other of the plurality of temperature control member 400 is tension It may be connected to the other end of the member 300.

In addition, when a plurality of tension members 300 are provided, one of the plurality of temperature regulating members 400 is connected to one end of the plurality of tension members 300, and the other of the plurality of temperature regulating members 400 is provided with a plurality of tension members 300. It may be connected to the other end of the tension member 300.

For example, the temperature control member 400 may be provided as a conductor and may transfer heat to the tension member 300 by receiving heat from an external heat source.

Alternatively, the temperature control member 400 may be provided as a thermoelectric element that directly converts electrical energy into thermal energy, and may directly heat the tension member 300 by receiving electricity from an external power supply.

Alternatively, the temperature regulating member 400 may be provided as a spiral coil and may heat the tension member 300 by generating an AC magnetic field by receiving electricity from an external power supply.

However, the example of the temperature control member 400 is not limited thereto, and any one may be used as long as the temperature of the tension member 400 can be adjusted.

As such, the temperature of the tension member 300 may be adjusted by the temperature regulating member 400, and in particular, the length of the tension member 300 may be shrunk by increasing the temperature of the tension member 300.

In the formula for calculating the compressive force introduced by the tension member 300 as described above, the length change amount of the tension member 300 is related to the temperature control member 400, the temperature control member 400 or the temperature control member ( It may be controlled by the control of an external heat source or an external power source connected to 400.

As such, the tension force or the compressive force introduced by the hydration heat reaction during curing of the pouring material C may be transmitted to the first modular member M1 and the second modular member M2 through the connection unit 10.

In addition, by detecting the tension loss of the tension member (S50), by applying heat to the tension member (S60), the loss of the bonding force due to the relaxation (relaxation) of the tension member, drying shrinkage and damage of the pour material is subsequently generated When occurring, the tension member or the second modular member M2 may be induced again in the first modular member M1 and the second modular member M2 by contracting the tension member.
