Abstract
The invention discloses a vertical structure column reinforced steel bar preferentially constructed method for a reverse building method. The vertical structure column reinforced steel bar preferentially constructed method for the reverse building method includes the following steps that 1, column joint bars are preserved when a first layer of board in a reverse building method project is constructed; 2, when a first underground floor is constructed, a main column bar and the column joint bars are connected through inner threaded sleeves, the main column bar penetrates through the first underground floor to a second underground space, the main column bar is sleeved with column hoops at the same time, the main column bar and the column hoops are connected in a binding mode, and construction of the portion, in the first underground space, of the main column bar is achieved; and 3, the step 1 and the step 2 are carried out repeatedly until an underground base plate is constructed circularly. The vertical structure column reinforced steel bar preferentially constructed method for the reverse building method achieves the effects of reducing steel consumption, reducing workloads and avoiding environmental pollution caused by electric welding operation.
Description
Technical field
The present invention relates to technical field of building construction, particularly to a kind of contrary sequence method vertical structure preferential construction party of post reinforcing bar
Method.
Background technology
Existing reverse construction carries out after bottom slab concreting completes vertical structure construction again, so every layer of horizontal junction
Post joint bar need to be reserved the when of structure construction, stay in and with reinforcing bar, upper and lower two ends joint bar is carried out colligation again when vertical structure starts to construct
Overlap joint, stirrup construction, seals mould again and pours, and such sequence of construction not only reinforcing bar use cost is big but also the duration is big.
Summary of the invention
In order to solve at least one problem mentioned in background technology, the present invention provide one can save splice and
And can the contrary sequence method vertical structure preferential construction method of post reinforcing bar of reduction of erection time.
To achieve these goals, the invention provides a kind of contrary sequence method vertical structure preferential construction method of post reinforcing bar, bag
Include following steps:
Step 1: the first floor plate in contrary working method engineering reserves cylinder joint bar when constructing；
Step 2: when B1 floor slab construction, uses inner thread sleeve to be carried out with described cylinder joint bar by main for cylinder muscle
Connect, and by main for cylinder muscle through B1 floor in the sheaf space of underground two, column tie-bar is inserted in the main muscle of cylinder simultaneously, adopts
Connect with colligation, to reach the construction of the B1 space main muscle of middle column body；
Step 3: repeat the above steps 1 and step 2, till being recycled to ground lower shoe.
Optionally, it is characterised in that: described cylinder joint bar two ends are provided with external screw thread.
Optionally, the two ends of adjacent described cylinder joint bar are not at sustained height.
Optionally, stagger between a length of 500mm～1000mm in the end of adjacent described cylinder joint bar.
The beneficial effect of the contrary sequence method vertical structure preferential construction method of post reinforcing bar of the present invention: contrary sequence method vertical structure of the present invention
The preferential construction method of post reinforcing bar carries out the construction of top vertical structure while construction of bottom plates, uses the post reinforcing bar of one-part form even
Connect mode, every layer of single steel bar only with a sleeve, splice can not only be saved and can the reduction of erection time.
Accompanying drawing explanation
Fig. 1 is the constructing structure schematic diagram of the contrary sequence method vertical structure preferential construction method of post reinforcing bar of the present invention.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawing each reality to the present invention
The mode of executing is explained in detail.But, it will be understood by those skilled in the art that in each embodiment of the present invention,
In order to make reader be more fully understood that, the application proposes many ins and outs.But, even if there is no these ins and outs and base
Many variations and amendment in following embodiment, it is also possible to realize the application each claim technical side required for protection
Case.
The present invention solves above-mentioned technical problem, the invention provides a kind of contrary sequence method vertical structure post reinforcing bar and preferentially construct
Method, in conjunction with Fig. 1, is described in detail the present embodiment.
Fig. 1 is the constructing structure schematic diagram of the contrary sequence method vertical structure preferential construction method of post reinforcing bar of the present invention, and the present invention carries
Supply a kind of contrary sequence method vertical structure preferential construction method of post reinforcing bar, comprised the following steps: step 1: in contrary working method engineering
Cylinder joint bar 10,11 is reserved during the construction of first floor plate；Step 2: when B1 floor slab construction, uses inner thread sleeve by cylinder
Main muscle is attached with described cylinder joint bar 10,11, and by main for cylinder muscle through B1 floor in the sheaf space of underground two,
Column tie-bar 14 is inserted in the main muscle of cylinder simultaneously, uses colligation to connect, to reach the construction of the B1 space main muscle of middle column body；Step
Rapid 3: repeat the above steps 1 and step 2, till being recycled to ground lower shoe, described cylinder joint bar 10,11 two ends 12,13 set
Having external screw thread, the two ends 12,13 of adjacent described cylinder joint bar are not or not sustained height, the two ends of adjacent described cylinder joint bar
12,13 stagger between a length of 500mm～1000mm.
While B1 horizontal structure is constructed, vertical reinforcement reserved by reinforced column, and length in reserve should meet
" concrete structure engineering construction quality accident specification " GB50204-2002 (2011 editions) requirement, constructs at next layer of horizontal structure
While, post reinforcing bar and a upper post reserving rib are carried out sleeve connection, and is left to next layer in advance, reach vertical posts with this way
The purpose of the one-stop connection of reinforcing bar, column tie-bar of simultaneously constructing in the lump, save the splice that separately construction two joint bar connects
With the pillar reinforcement construction cycle, and while construction of bottom plates, carry out pouring of concrete column, thus reach the reduction of erection time and
Save the purpose of Financial cost.The form of construction work of vertical reinforcement in above-mentioned contrary sequence method, by using joint bar, sleeve connection, rather than
Conventional electric welding connection or colligation connect, and have reached save steel consumption and reduce workload and the ring avoiding electric welding field to produce
The effect of environment pollution；The main muscle of cylinder and stirrup are constructed simultaneously and have been reached the effect of reduction of erection time.
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific embodiment of the present invention,
And in actual applications, can to it, various changes can be made in the form and details, without departing from the spirit and scope of the present invention.
