Workshop column retrofitting

General situation of reinforcement engineering

1, this project is Qingtian County home hardware locks Co. Ltd. 1# production workshop, is a column retrofitting project, according to the requirements of design drawings, the project only to the local component of the original structure is reinforced.

2. The main strengthening methods are: the rrtrofitting of the original concrete column: the method of enlarging cross section by HM-500 anchoring adhesive and the method of epoxy bonded steel plate.

In accordance with the actual characteristics of the site and the structural features to be reinforced, the damage to the original structure is guaranteed.

The principle of strengthening engineering

1) the strengthening quality directly affects the structural quality and structural safety of the project, and the principle of strengthening is to take the bottom-up order according to the requirements of the design drawings.

2) before construction, according to the original design drawings and design drawings of the structure of comprehensive detection section size of the original structure, and reinforcement of structure reinforcement is consistent with the drawings, which is inconsistent with the design drawings to inform design process, to the original structure were measured before construction.

3) to ensure that the construction does not cause any damage and damage to the original structure, the construction shall not be used in large noise and strong vibration of mechanical anchorage by hammer drilling, which meets the design requirements of building structure adhesive anchorage; according to the drawing requirements method using direct bonded steel or plastic injection pressure of steel reinforcement.
