化学植筋方法（Methods of chemical planting） Transfer to a web of love papers Henan medical university first affiliated hospital of new ward building project, in the process of construction, due to party as requirement, in order to strengthen the overall effect, on the roof of the already finished, increase 30 m high tower, due to large tower load, the original design did not consider the tower corresponding load and the foundation, therefore, the original design can not meet the requirement of the load, to the original roof structure reinforcement reinforcement processing measures. I. programme design and use scope According to the site condition and tower piers location, issued by the design institute of tower pier reinforcement reinforcement figure, concrete beam under the piers and wall reinforcement measures, piers under the original design of shear wall to take to increase the vertical reinforcement pier with the technology of anchor bar and into the wall (see attached figure A.B.C section). It is necessary to add a layer of support column from the next layer of shear wall to the base of the frame beam. The diameter of steel reinforcement bars in this engineering is phi 14, phi 22, and phi 25. The implant USES the method of drilling the core. The structure glue knot, the specific plan detailed see the attached drawing. In this paper, the application of the anchorage technology is discussed and the other parts are not discussed. The characteristics of MLJ structural glue: the installation is convenient and quick and the location is accurate. The anchorage force is large, the anti-seismic performance is good, the failure state is the anchorage end concrete cracking or the reinforcement deformation, without pulling out the phenomenon; The structure adhesive can be quickly cured and can be carried rapidly. Horizontal and vertical holes are easy to build and can be filled with glue. The properties of structural glue are mainly epoxy resin. The advantages are as follows: E
