Description
Technical field
The present invention relates to a kind of bracing members node structure and construction method thereof.
Background technology
Shanghai belongs to Quaternary system river mouth, strand, shallow sea, drowned valley, paludal facies sedimentary deposit, belongs to typical Soft Clay condition, primarily of saturated clayey soil, silty soil and sand composition, has the feature of stratification distribution.Carry out excavation of foundation pit and internal construction under its geology to return to build there is the unmanageable feature of distortion, and for guaranteeing foundation ditch and safety of surrounding environment, returning in the process of building in internal construction and leaving bracing members.Existing construction technology is primarily of two kinds of forms, the first adopts H profile steel as steel pad case, and at steel pad case periphery welding water-stopping steel sheet, guarantee stagnant water effect, it two is built-in steel sleeves, at sleeve inner erection bracing members, treat that main structure construction is complete, after concrete strength reaches designing requirement, remove sleeve inner bracing members, sleeve inner adopts the concrete of label identical with agent structure to fill; And these two kinds of methods all exist shortcoming, adopt H profile steel as steel pad case way, exist in H profile steel position coagulation grave mould difficulty, very easily occur leaking oar phenomenon, this position vibrating spear affects by steel pad case, and padding case lower concrete cannot vibration compacting, cause internal construction percolating water, and adopt steel bushing form, after bracing members is removed, sleeve inner is owing to building for level, not easily build closely knit, cause percolating water, and construction in later period is numerous and diverse, need formwork again, carry out concreting.
So, develop a kind of bracing members dot structure and the construction method thereof that can solve the bracing members position leakage problem being retained in agent structure inside, just become the problem that insider needs solution badly.
Summary of the invention
For the above-mentioned technical problem in correlation technique, the present invention proposes a kind of bracing members node structure and construction method thereof, can solve the bracing members position leakage problem being retained in agent structure inside.
For realizing above-mentioned technical purpose, technical scheme of the present invention is achieved in that
A kind of bracing members node structure, comprise steel pipe, described steel pipe one end is provided with the end plate matched, the steel plate matched also is provided with in described steel pipe, and the outside of described steel pipe is connected with by the steel pad case fixed head of some even arrangements the bracing members end plate matched, and the outside of wherein said steel pipe is also provided with some water-stopping steel ring flat-plates between described steel plate and described end plate.
A construction method for bracing members node structure, comprises the steps:
Step one: at the end plate of one end of steel pipe welding with ribs, the other end is open type;
Step 2: steel duct distance open end 350mm or 550mm position full weld one piece of thickness be the steel plate of 6mm;
Step 3: outside steel pipe, the bracing members end plate that one piece of thickness is 6mm, width is 120mm is welded in inwall centre position;
Step 4: build the concrete that same internal construction label is identical in described steel pipe between steel plate with end plate;
Step 5: steel pipe is connected on pre-configured bracing members by welding or bolted mode, described bracing members is set up;
Step 6: treat that internal construction concreting is complete, when reaching design strength, cuts off steel pipe pad case, removes and support, and repairs residue 5cm hole.
Further, in step one when inwall thickness is 400mm, described steel pipe length is 650mm, and described concreting thickness is 350mm; When inwall thickness is 600mm, described steel pipe length is 850mm, and described concreting thickness is 550mm.
Beneficial effect of the present invention: the present invention can guarantee the concrete pouring quality of correspondence position, avoid the operation that the later stage builds, and this structure meets the requirement of bracing members termination intensity, effectively decreases the percolating water phenomenon of internal construction.
