Description
Technical field
The present invention relates to syndeton and construction method between a kind of existing building, belong 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, and produce development, and people are to existing eachThe use function that class is produced, room is used in life and condition can constantly propose new requirement, make its constantly needs of adaptation new situations development,Must have like this engineering that existing building is transformed.
At present, in China's old room transformation process, often can run into because of development and manage needs, needing adjacent two buildings to be connected toOne, increases usable floor area or makes walking convenient. The particularly building such as market, hospital and school, but consider two adjacent buildingBuild and the version difference of newly-increased coupling part, its intrinsic frequency, amplitude difference, be subject to temperature, earthquake or other stronger shakingUnder moving impact, the distortion difference of generation, two adjacent architecturals easily produce structural deterioration, and event even collapses.
Summary of the invention
In order to overcome the problems referred to above, the present invention proposes syndeton and construction method between a kind of existing building. Use slip rubberBearing, as the connected node of two adjacent architecturals, has solved two buildings with different natural frequencies, amplitude after structure connectsReceive and when earthquake or other are compared with strong vibration, produce a difficult problem for structural deterioration.
Technical scheme of the present invention is as follows:
Syndeton between a kind of existing building, comprises adjacent existed building first and existed building second, described existed building first andThe relative both sides of existed building second are provided with row's frame column, on described frame column, are provided with encased steel plate, frame column and outsourcingBetween steel plate, adopt chemical anchor bolts to connect, encased steel plate one side is welded with bracket, and main girder steel is arranged on bracket, main girder steelAnd between bracket, adopt slip rubber support as connected node, between each main girder steel, adopt groined type to interconnect,The newly-increased coupling part of common composition one, thus adjacent existed building first and existed building second are coupled together.
Described encased steel plate thickness is 20mm.
Described main girder steel is I-steel.
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 rubber support 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 useChemical anchor bolts are connected it 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 rubber support is installed on bracket, and the rubber support that respectively slides should be accurately in place, and keep at grade,There is eccentric compression phenomenon in the rubber support of avoiding sliding;
Step 5: on each slip rubber support, main girder steel is installed; When main steel girder erection, for preventing main girder steel and slip rubber supportThere is horizontal sliding, need be first with wooden triangle cushion block in the interim positioning supports in main girder steel both sides, treat that main steel girder erection work is all completeAfter finishing, remove;
Step 6: will between the main girder steel on each bracket, adopt groined type to interconnect, 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, and adopts slip rubber support not only canMake support node large compression, obtain enough bearing capacities in the case of not occurring, and collaborative two adjacent architecturals is intrinsicAmplitude, frequency, thus eliminate or reduce temperature, the destruction of distortional stress to original structure, simultaneously again can balanced bottom bracing structureStress, and the method is simple in structure, it is convenient to install, change, service time is long.

Detailed description of the invention
The specific embodiment of the present invention is as follows:
As shown in Figure 1-2, syndeton between a kind of existing building of the present invention, comprises adjacent existed building first 1 and existingBuilding second 2, existed building first 1 both sides relative with existed building second 2 are provided with row's frame column 3, on each frame column 3Being provided with thickness is the encased steel plate 4 of 20mm, and between frame column 3 and encased steel plate 4, adopting diameter is the chemistry of 20mmCrab-bolt 5 connects, and all arranged in a crossed manner on 4 four faces of encased steel plate have many chemical anchor bolts 5. Encased steel plate 4 one sides outsideSide is welded with bracket 6, and main girder steel 7 is arranged on bracket 6, and main girder steel 7 adopts I-steel, between main girder steel 7 and bracket 6Adopt slip rubber support 8 as connected node, between main girder steel 7 bottom surfaces and slip rubber support 8 end faces, adopt bolt to fix.Between each main girder steel 7, adopt groined type to interconnect, jointly form a newly-increased coupling part 9, thereby by adjacentExisted building first 1 and existed building second 2 couple together. On newly-increased coupling part 9, also can lay steel plate or concrete prefabricated board.Wherein, the bracket 6 on frame column 3 is one or more layers, and every layer of bracket 6 upper surface absolute altitude are consistent.
The construction method of above-mentioned syndeton, comprises the following steps:
