Abstract
A kind of full construction method for disconnecting Long-span Cantilever system support at construction joint, include the following steps: 1. along construction joint be arranged interim constructional column and with its integrally formed frame beam plate；Interim constructional column arrangement of reinforcement is configured by formal structure column and lintel or wall waist rail reinforcing bar and is calculated by bearing capacity, and three takes large values；2. being laid with one layer of separation layer in temporarily construction column bottom；3. carrying out the examination of interim constructional column reinforcing bar, progress formwork erection and template to check and accept and pour together with the frame beam plate of upper layer；4. being connect with the construction of opposite subregion, interim constructional column is removed after reaching design strength, can be used for the constructional column that secondary structure wall utilizes will not remove, and wall lacing wire bar planting is carried out when formally building.Construction cost of the present invention is low and can carry out the utilization again of secondary structure.
Description
Technical field
The invention belongs to building engineering fields, are a kind of full construction parties for disconnecting Long-span Cantilever system support at construction joint
Method.
Background technique
In building field, for traditional substantially quantifier mesh, typically subregion piecemeal is constructed, and each subregion re-forms
Respective flowing water section.Using this usage mode first is that the reason of designing itself, mainly from the angle of structure sediment the considerations of, two
It is unit in charge of construction's self reason, from the aspect of the investment for reducing turnover material tool, saves cost.Sometimes and construction field
The reason of ground itself, construction site is narrow, can not large area development construction.
But found after the summary of traditional construction joint can be generated by this construction method, traditional construction seam is divided into complete
It disconnects and part disconnects, complete disconnect refers to that reinforcing bar at construction joint, template, concrete all disconnect, and part, which disconnects, refers to concrete broken
It opens, reinforcing bar is disconnected or continuous, and template does not turn off.At present for disconnect full type construction joint mainly use steel pipe scaffold or steel column into
Row support, construction cost is high and can not carry out the utilization again of secondary structure.
Summary of the invention
The object of the invention is that overcome above-mentioned the deficiencies in the prior art, and provide a kind of construction cost it is low and
It can carry out the construction method that Long-span Cantilever system supports at the full disconnection construction joint of secondary structure utilized again.
As above design, the technical scheme is that a kind of complete disconnect applying for Long-span Cantilever system support at construction joint
Work method, characterized by the following steps:
1. along construction joint be arranged interim constructional column and with its integrally formed frame beam plate；Interim constructional column arrangement of reinforcement is by just
Formula constructional column and lintel or wall waist rail reinforcing bar are configured and are calculated by bearing capacity, and three takes large values；
2. being laid with one layer of separation layer in temporarily construction column bottom；
3. carry out the examination of interim constructional column reinforcing bar, carry out formwork erection and template check and accept and with upper layer frame beam plate one
It rises and pours；
4. being connect with the construction of opposite subregion, interim constructional column is removed after reaching design strength, can be used for secondary
The constructional column that structure wall utilizes will not be removed, and wall lacing wire bar planting is carried out when formally building.
The separation layer uses one layer of malthoid or Polypropylene.
The present invention has the advantage that and good effect: 1, the present invention changes conventionally employed steel pipe scaffold or steel column
Support, has saved construction cost.2, the present invention carries out interim structure according to the size of secondary structure thickness of wall body, lintel and waist rail
It makes the design of column cross-section size and arrangement of reinforcement and carries out the accounting of interim construction columns bearing capacity, and in the arrangement side of interim constructional column
Face, takes into account the position of secondary structure wall, and these two aspects ensure that the utilization again of secondary structure.3, for the construction of dismounting
Column is cut using toothless saw, is used as later period wall waist rail and lintel.Can secondary use, and can save and be constructed into
This.Calculated thus much one just cost-saved 1,200,000 yuan.
Detailed description of the invention
Fig. 1 is the arrangement schematic diagram of interim constructional column；
Fig. 2 is the A direction view of Fig. 1；
Fig. 3 is the schematic diagram of interim constructional column；
Fig. 4 is the side view of Fig. 3.
In figure: the interim constructional column of 1-；2- Vierendeel girder；3- frame column；4- shear wall；5- separation layer.
Specific embodiment
It is as shown in Figs 1-4: a kind of full construction method for disconnecting Long-span Cantilever system support at construction joint, including walk as follows
It is rapid:
1. along construction joint be arranged interim constructional column and with its integrally formed frame beam plate；Interim constructional column arrangement of reinforcement is by just
Formula constructional column and lintel or wall waist rail reinforcing bar are configured and are calculated by bearing capacity, and three takes large values；
2. being laid with one layer of separation layer in temporarily construction column bottom；
3. carry out the examination of interim constructional column reinforcing bar, carry out formwork erection and template check and accept and with upper layer frame beam plate one
It rises and pours；
4. being connect with the construction of opposite subregion, interim constructional column is removed after reaching design strength, can be used for secondary
The constructional column that structure wall utilizes will not be removed, and wall lacing wire bar planting is carried out when formally building.
5. carrying out concentration stacking for removing pillar, the later period uses as doorway lintel or wall waist rail.
The separation layer uses one layer of malthoid or Polypropylene.The interim constructional column position, which is arranged, will take into account secondary knot
The position of structure wall.
The above embodiment is used for illustrative purposes only, rather than limitation of the present invention, the technology in relation to technical field
Personnel can also make various transformation or variation without departing from the spirit and scope of the present invention.Therefore, all etc.
Same technical solution also should belong to scope of the invention, should be limited by each claim.
