On embedded part, the cylinder for after applies prestressing force and provides fixing end.Afterwards again start lift bottom layer node post, lift it is adjacent across
During beam, following two construction technologies are taken：Arrangement is spread from corner to center, or arrangement is spread from center to side.
Corner is to center arrangement：After the completion of corner post 1a assemblings, transport transverse and longitudinal adjacent across beam a, b to floor height
Place, one end is erected on post on pre-buried angle steel 6, and the other end is first fixed with equipment.Two adjacent with the longitudinal axis and transverse axis are set up again
Root node column 2a, 3a, before this, the beam near corner post on column 2a, 3a connects semifixed anchor is worn on prestressed pore passage 5
Tool.Next connecting prestressed pore passage 5 in beam wears presstressed reinforcing steel, the circle of the semifixed anchorage on the front pillar that presstressed reinforcing steel is needed guiding through
Hole.Fixed with anchorage at two ends after the tensioning of two ends, the anchorage is placed in post side groove 13, the beam-ends fixing equipment before releasing is entered
The assembling of next group of row.When carrying out the assembling of node post 4, beam c, d first pass through before semifixed anchorage on node post 2a, 3a
Presstressed reinforcing steel, roof beam structure one end is erected on the pre-buried angle steel 6 of 2a, 3a post, the other end is fixed with equipment.Again will along beam c,
The node post 4a assemblings that d directions have worn semifixed anchorage are in place, and cross girders c, d two ends tensioning is entered afterwards, and anchorage is fixed.One beam
Post rectangular cells just assemble completion, then above-mentioned steps are repeated, you can complete the assembling of flood.
Back enters the wet trade of andante again after the completion of this layer of beam column assembling, and setting reinforcing bar and plate at hole 9 is connected in the plate of beam
Muscle connects integral cast-in-situ, after the intensity of plate reaches to a certain degree by carry out next layer of assembling.
Adjacent layer be assemblied in complete all components of bottom assembling after, 1b is installed on 1a so that 1a tops insert
Muscle hole 3 is mutually twisted with the joint bar 4 of 1b bottoms, completes to fix after the treatment of the cement mortar cementation of fissures, according to the similar dress of ground floor
Method of completing the square can equally complete the assembling of the second layer and pouring for plate, be finally completed the prestressing force assembling of agent structure.
After the completion of overall structure assembling, the prestressed stretch-draw anchor of cylinder is carried out on top mode post, complete node
Combining closely for post, completes structurally waterproof by the cementation of fissures treatment that the seam default wide of its all outer surfaces carries out cement mortar afterwards.
Center is arranged to side：It is consistent with above-mentioned settled principle, but different with the requirement in place can be adopted based on the duration
Take the mode of being implemented as follows：
The column 1a at overall structure center is chosen, all of beam of surrounding connects prestressed pore passage 5 and wears semifixed anchorage, diagonally
It is alternately interspersed, on the basis of being placed in.Four erections of beam are carried out simultaneously, and beam a, b, c, d are each passed through the semifixed anchorage muscle at place,
It is erected on the pre-buried angle steel 6 of post 1a, the other end is fixed with four equipment.Column 2a, 3a, 4a, 5a of surrounding are leaned on again
The beam of nearly post 1a connects semifixed anchorage is worn on prestressed pore passage 5, and is positioned in basis.Next can two ends tensioning beam a,
Fixed with anchorage at two ends after b, c, d, the anchorage is placed in post side groove 13.Beam-ends fixing equipment before releasing, completes ten
Word cell is assembled.For example above-mentioned step of arrangement afterwards repeats conjunction and can both complete overall assembling to center arrangement method with reference to side
With structurally waterproof treatment.
Embodiment 2：Precast floor slab（Band door and window wall）Prefabricated PC structure
Early stage operation is identical with example 1, the assembling until completing post and lintel system.The assembly method of post and lintel system can also be taken
Next above-mentioned Bian Xiang centers and center carry out the assembling of prefabricated board and beam again to two kinds of side construction technology, take following method：
The plate that the elbow reinforcing bar of prefabricated board is inserted in beam to it is connected into hole 9, two bottom carry out elbow reinforcing bar it is substantially stationary i.e.
The combination of beam slab can be completed.If following also prefabricated wall, by wall body construction from top to bottom along post sideslip groove by wall
On body insert plate, while the convex key 12 of reinforcing bar on plate plays fixation to the bottom of wall.The overall assembling of bottom is completed, for
The assembly method of adjacent layer, adjacent layer can be completed with reference to the beam column assembly method of this layer of beam slab wall assembly method and example one
Overall assembling.Until structure is performed integrally assembling.
After the completion of overall structure assembling, the prestressed stretch-draw anchor of cylinder is carried out on top mode post, complete node
Combining closely for post, completes structurally waterproof by the cementation of fissures treatment that the seam default wide of its all outer surfaces carries out cement mortar afterwards.
This case method can more meet the requirement of quick-assembling, substantially depart from wet trade operation.With good application prospect.
