Description

When remodeling an apartment building, check the bearing capacity of the existing foundation pile and use the existing structure (base plate and load-bearing wall) as a load reaction force. {A method of using loading devices and existing structures to verify the support of existing foundation piles when remodeling existing apartments}

The present invention relates to a static load test apparatus that checks the bearing capacity of the foundation piles constructed previously during apartment building remodeling and uses the existing structure as a load reaction body, particularly when supporting the building load for additional vertical and horizontal extensions during apartment building remodeling. The pile foundation is to be constructed. At this time, in order to design the load sharing borne by the existing piles and the new piles, load loads are applied to the existing pile foundation so that the bearing capacity can be evaluated. And it relates to a static load test device using the existing structures (base plate and load-bearing wall) as a load reaction force.

In general, when there is a need to enlarge (extension) the size of an existing structure, such as an apartment remodeling, it was a common method to remove a part of the existing structure, expose the existing pile, and then load the existing pile. To explain in detail as a method that compensates for the cost and time consuming in the case of such a general method, the conventional test apparatus has widely used the method of artificially creating a reaction load and loading it.

That is, in general, when it is necessary to enlarge (extension) the size of an existing structure, such as apartment remodeling, when a subsidence occurs in an existing structure, and when repair and reinforcement of existing piles are required, the lower part of the existing structure If you want to extend the underground structure in the basement, the construction method of forming a through hole in the existing base plate and constructing additional piles is applied.

On the other hand, Registration No. 10-1494260 (published date: 20150217) disclosed in the Republic of Korea Patent Publication relates to a pre-load loading device for piles and a pre-load loading method using the same. Here, as it relates to a wire loading device using a footing, that is, there is a problem that a large supporting load of several tens of tons or more cannot be applied because it does not have a separate device that maintains the load loaded on the pile by applying a preceding load.
