Description

Building Core System using Precast Concrete Box Shaped Modules with Connection Hardware at Corners And Core System Construction Method Using Thereof}

The present invention relates to a box-type precast concrete module having a bonded hardware at the corner and a building core system construction method using the same, and more particularly, to install the bonded hardware at four lower corners of the box-shaped concrete module, and to the upper corner, four corners. The present invention relates to a box-type precast concrete module having a bonded hardware at a corner portion in which a PC core (staircase and elevator shaft) can be stacked in a short time by laminating an box-type module by embedding an anchor in the part, and a method for constructing a building core system using the same.

In general, the core of a building is a structural element that promotes horizontal stability of a building by forming a concrete shear wall structure by concentrating a vertical transportation system and an energy supply system to resist horizontal forces along with surrounding frames. The member that transmits the lateral force to the core is the floor slab of the building, and serves to make the core and the surrounding frame like a large concrete pipe behave as a structure. In the case of high-rise buildings, the RC core leading method is applied to find the horizontal stability of the building by using the difference between the wall structure and the ramen structure by pre-installing the core in the wall structure and post-installing the surrounding steel ramen structure.

The RC core leading method requires formwork systemized for installation, fixing, and dismantling, and the method of processing the joints for continuous reinforcing bars in the core should be devised. In addition, there is interference between the stud bolt and the reinforcing steel in the corner part, air delay due to the on-site reinforcement of the reinforcing steel, and shape deformation is inevitable when lifting the prefabricated steel.

In the United Kingdom, where there is little impact from earthquakes, there are increasing cases of construction of PCs using stairs and elevator shafts, which are vertical passages of high-rise buildings, as shown below. However, since the staircase and the elevator shaft are not used as lateral resistance elements, the joining between the PC units is relatively simple to have a resistance against member forces due to vertical loads.

On the other hand, the elevator shaft is constructed by stacking one PC unit per floor when the space constraints of the site and the capacity limitations of the lifting equipment are less, or a construction method of alternately stacking the door unit and the pulling unit.

On the other hand, the stairs have not been applied to the box-shaft due to the weight of the weight, and the method of connecting the stairs and landings in the paneled space has been applied.In recent years, the construction of the stairs into the box-type stairs has been studied. . However, in the case of the staircase room, since the space is larger than the elevator shaft, it is difficult to manufacture a single layer as a single unit due to the large weight, and because the additional installation of stairs and landings, etc., the connection to this also acts as a limiting factor.

In particular, the existing PC cores (stair room and elevator shaft) are limited in horizontal bonding between PC units (inverse proportionality of joining details / location and construction), and when the space is constructed using PC panels, lateral resistance resistance is impossible due to the possibility of horizontal reinforcing bars. There was a problem such as the individual behavior of the PC unit due to the sharp drop in and the lack of reliability of joint strength.

As a background art of this invention, Unexamined-Japanese-Patent No. 2012-0003172 "The building core part construction method of a module lamination system" (patent document 1). In the background art, a construction site is manufactured by manufacturing a core structure 10 including an elevator chamber 11 having upper and lower openings and a staircase chamber 12 having an inclined plate 13a and a landing 13b in a standardized module form. In the stacking construction is performed, the building beams of the modular stacking method is characterized in that the holding beams 14 of the core structures 10 are mutually fastened and assembled by a fastening member.

However, since the background art has problems such as the individual behavior of the PC unit due to the sharp deterioration of the lateral force resistance performance and the lack of reliability of the joint strength, it is not only used as a lateral force resistance element, but also has difficulty in lifting and construction.
