Abstract
The invention relates to a connecting structure for existing buildings and a construction method and belongs to the technical field of reinforcement and reconstruction. The connecting structure comprises the existing building A, the existing building B, frame columns, outer wrapping steel plates, brackets, main steel beams and sliding rubber supports. The outer wrapping steel plates are arranged on the original frame columns. The outer wrapping steel plates and the frame columns are connected through chemical anchor bolts. The brackets are welded to the steel plates. It should be ensured that the elevations of the upper surfaces of the brackets in each layer are consistent. The additionally arranged main steel beams are seated on the brackets. The main steel beams are joist steel, and the sliding rubber supports serve as joints. According to the connecting structure, the sliding rubber supports are adopted as the connecting joints between two adjacent buildings, and therefore the problem that two buildings with different inherent frequencies and amplitudes are prone to structural damage when receiving an earthquake or other strong vibration after structural connection is solved.

Described encased steel plate thickness is 20mm.
Described main girder steel is i iron.
Bracket on described frame column is one or more layers.Further, every layer of bracket upper surface absolute altitude is consistent.
All arranged in a crossed manner on four faces of described encased steel plate have many chemical anchor bolts.
Between described main girder steel bottom surface and slip neoprene bearing end face, adopt bolt to fix.
Described chemical anchor bolts diameter is 20mm.
On described newly-increased coupling part, be equipped with steel plate or concrete prefabricated board.
The construction method of syndeton between above-mentioned existing building, comprises the following steps:
Step 1: according to design drawing, the first basis of reinforcing frame trestle, to meet the load of bearing newly-increased coupling part, top;
Step 2: respective design position arranges encased steel plate on the frame column of existed building first and existed building second opposite side, and it is connected with frame column with chemical anchor bolts;
Step 3: at encased steel plate one side welding bracket, bracket absolute altitude is determined according to design drawing;
Step 4: slip neoprene bearing is installed on bracket, and the neoprene bearing that respectively slides should be accurately in place, and keep at grade, there is eccentric compression phenomenon in the neoprene bearing of avoiding sliding;
Step 5: on each slip neoprene bearing, main girder steel is installed; When main steel girder erection, for preventing main girder steel and slip neoprene bearing generation horizontal sliding, need be first with wooden triangle cushion block in the interim positioning supports in main girder steel both sides, treat to remove after main steel girder erection work all;
Step 6: will adopt groined type to interconnect between the main girder steel on each bracket, form a newly-increased coupling part, adjacent existed building first and existed building second are coupled together.
Beneficial effect: the present invention has well solved the difficult problem that two adjacent different buildings connect, adopt slip neoprene bearing not only can make support node large compressive strain, obtain enough bearing capacities in the case of not occurring, and intrinsic amplitude, the frequency of collaborative two adjacent architecturals, thereby eliminate or reduce temperature, the destruction of distortional stress to original structure, stress that simultaneously again can balanced bottom bracing structure, and the method is simple in structure, it is convenient to install, change, and service time is long.
