Abstract
The utility model relates to a connecting structure between the existing buildings, and belongs to the technical field of reinforcement and transformation. The connecting structure comprises a first existing building, a second existing structure, framework posts, outer covering steel plates, corbels, main steel beams and sliding rubber support seats, wherein the outer covering steel plates are arranged on original framework posts; chemical anchor bolts are adopted for connection; the corbels are welded on the steel plates; the identical elevation of the upper surfaces of the corbels arranged at each layer needs to be ensured; the newly added main steel beams are seated on the corbels; the main steel beams are I-shaped steel; and nodes adopt the sliding rubber support seats. The connecting structure has the advantages that the sliding rubber support seats are adopted to be used as the connecting nodes of the two adjacent buildings; and the problem of structure damage generated when the two buildings with different inherent frequencies and amplitudes are suffered from earthquake or other strong vibration after the structure connection is solved.
Description
Technical field
The utility model relates to syndeton between a kind of existing building, belongs to strengthening reconstruction technical field.
Background technology
Along with living standards of the people improve constantly, rural and urban construction plans are constantly looked for novelty, produce development, people can constantly propose new requirement to existing all kinds of productions, life by use function and the condition in room, make it constantly adapt to the needs of new situations development, must have the engineering that existing building is transformed like this.
At present, in China's old room transformation process, often can run into because of development and manage needs, needing adjacent two buildings to connect as one, increasing usable floor area or make walking convenient.The building such as market, hospital and school particularly, but the form of structure of considering two adjacent architecturals and newly-increased coupling part is different, its intrinsic frequency, amplitude difference, be subject under the impact of temperature, earthquake or other stronger vibrations, the distortion producing is different, two adjacent architecturals easily produce structural deterioration, and event even collapses.
Utility model content
In order to overcome the problems referred to above, the utility model proposes syndeton between a kind of existing building.Connected node with slip neoprene bearing as two adjacent architecturals, has solved two buildings with different natural frequencies, amplitude and after structure connects, has received and when earthquake or other are compared with strong vibration, produce a difficult problem for structural deterioration.
The technical solution of the utility model is as follows:
Syndeton between a kind of existing building, comprise adjacent existed building first and existed building second, the described existed building first both sides relative with existed building second are provided with row's frame column, on described frame column, be provided with encased steel plate, between frame column and encased steel plate, adopt chemical anchor bolts to be connected, encased steel plate one side is welded with bracket, main girder steel is arranged on bracket, between main girder steel and bracket, adopt slip neoprene bearing as connected node, between each main girder steel, adopt groined type to interconnect, the common newly-increased coupling part that forms, thereby adjacent existed building first and existed building second are coupled together.
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, first the basis of reinforcing frame trestle, bears to meet the load that top increases coupling part newly;
Step 2: respective design position arranges encased steel plate on the frame column of existed building first and existed building second opposite side, and with chemical anchor bolts, it is connected with frame column;
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 each neoprene bearing that 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; During 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 utility model has well solved the difficult problem that two adjacent different buildings connect, adopt slip neoprene bearing not only can make support node in the situation that do not occur that large compressive strain obtains enough bearing capacities, 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.
