Jaeha Jeong test apparatus for apartment building remodeling {loading devices and existing structures to verify the support of existing foundation piles when remodeling existing apartments}

The present invention relates to a static loading test apparatus for remodeling an apartment building, and in particular, performing a static loading test using an existing structure when remodeling an apartment building, and measuring polluted air to protect workers. It is related to the Jeong Jae-ha test equipment.

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.

In addition, Registration No. 10-1631219 (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, unlike Registration No. 10-1494260, a separate device is installed in the footing to maintain the potential load loaded on the pile, including the preload load device, by the preceding load fixing support unit and the screw thread. It is composed of a load pressurization unit. However, these two units are in the form of permanent storage, and they are expensive and disadvantageous in terms of economics, and they are difficult to use in reality because construction also undergoes a complicated process.

The present invention is intended to solve the above problems, and when it is necessary to enlarge (extension) the scale of an existing structure, it is possible to stably load the foundation structure without removing some of the existing structure and installing a load reaction arm. Its purpose is to provide a load-bearing device for piles that allows

In addition, the present invention additionally installs a polluted air measuring device at the work site to protect workers, and if it is determined that the polluted air measuring device is in a polluted state, the purpose of the present invention is to additionally configure the device so that the worker can be evacuated. .
