Description

Construction method and structure of joint joint of precast concrete panel and panel for architectural remodeling {METHOD EXECUTION FOR JOINTING BETWEEN PRECAST CONCRETE PANELS FOR BUILDING REMODELING}

The present invention relates to a method for joining panels and joints of panels when remodeling old aged buildings using precast concrete panels. More specifically, when the precast concrete (PC) panel is installed on the inner wall or the outer wall between the pillar and the pillar of the building, watertight hoses are installed on the front and rear surfaces of the joint to which the PC panel and the PC panel correspond. The joints of the precast concrete panels and panels for architectural remodeling, in which the joints are overlapped with each other and then mortar grouted, the joints are firmly joined to withstand the tension for the transverse support and the load for the longitudinal reinforcement. The present invention relates to a subjoin construction method and structure.

The urban buildings we live in today coexist with buildings built decades ago and buildings built recently. Therefore, existing buildings and recently constructed buildings have different design reflections according to the building law, so the seismic design of existing buildings is not reflected at all, resulting in the destruction of buildings such as schools, buildings, and large buildings at small magnitudes. There was a problem that damage occurred.

In recent years, the rapid increase in urbanization has led to a sharp increase in the demand for housing, the improvement of the demand for quality and utilization of aging inventory, the need for environmentally friendly building management policies, and the prevention of land development due to indiscriminate new construction. Remodeling is recommended from the standpoint of the present invention, and as a result, interest in remodeling is continuously increasing as an alternative to the demolition and construction of existing reinforced concrete buildings.

This remodeling activity has been mainly focused on special buildings such as offices, shopping malls, hospitals, etc., but recently the remodeling of the housing sector, especially high-rise apartment buildings such as schools and apartments, is being activated. Roh is expected to lead this entire remodeling market.

In addition, with the growing interest in the environment and the government's policy stance to reduce environmental waste and recycle the framing of existing apartments as much as possible in terms of economic efficiency, more apartments are choosing to remodel in addition to new construction or reconstruction. It is expected to do.

In order to remodel this old building, there is a method of stacking bricks or blocks on columns or inner and outer walls, but this method can tolerate compressive loads to some extent, but the tensile strength is considerably reduced in tensile strength, which does not improve the durability of the building. There is a problem.

Therefore, when looking at the prior art in this field, in the remodeling block for building walls of the "building renovation block" building of Patent No. 0583988 (hereinafter referred to as "prior art 1"), the stone, tile or brick of the remodeling block Finished outer wall portion 110; Filled with a liquid urethane insulating material inside the outer wall portion 110, the insertion portion 122 on one side in the longitudinal direction, and the protrusion 121 on the longitudinal tile side and the horizontal center projection 123. ) And a foamable resin material 120 formed of insertion parts 124 and 125 at both sides of the horizontal center protrusion. The remodeling block for building has been disclosed. The remodeling block coupling part 130 is formed in a shape of '┍' inside the foamable resin material 120 and is made of plastic to couple the remodeling block to an angle.

As another prior art, the "remodeling frame" of Patent No. 0589603 (hereinafter referred to as "prior art 2") is a frame to be embedded in a building to be remodeled and fitted with a window or door,

At least one pair of rails and guide protrusions on which windows or doors are mounted are arranged at both sides of the lower plate, both side plates mounted on the upper outside of the frame, the horizontal plate to which both plates are connected, and the upper side of the horizontal plate. A second frame provided with at least one material of metal or synthetic resin and fastened by the frame and the fastening member; It has been disclosed that a remodeling frame is provided.

Looking at the prior art, prior art 1 relates to a building remodel block, which is to finish the outer wall of stone or brick and to form a polyurethane insulation layer on the inside. Prior art 1 is intended to form aesthetics of the exterior wall during architectural remodeling, which is not suitable for seismic design of an aging building because there is no support for tensile force, and prior art 2 relates to a remodeled frame. It is configured to fix the frame on both sides of the wall to install the window between the walls and to support the window frame installed therebetween. This is also because the remodeling does not have the support for the tension of the panel fixed to one wall. There is a problem that does not have a seismic design and durability for the building.

The present invention is to solve such a problem as the joint between the PC panel and the PC panel installed on the window or wall of the building has a tensile force and at the same time when the mortar or concrete is injected between the joint mortar is injected into the front and rear of the joint The precast concrete panels and panels for building remodeling are designed to facilitate the work of the joints, which are the joints of PC panels, and to increase the strength against tension by installing watertight hoses to grout them. It relates to a joint construction method and structure.
