At present, the mounting means mainly dividing plate of staircase prefabricated reinforced concrete fire barrier is arranged on the marking time of precast stair, top is connected with stair base plate, this mounting means causes the complex-shaped of fire barrier, zigzag below, top is hypotenuse, adds the difficulty of making, reduces the service efficiency of platform mould；It addition, the stair gangboard of large span bears bigger load, stair cross section and arrangement of reinforcement increase accordingly；Additionally, fire barrier is the most all connected with stair, integral rigidity is big, easy to crack under geological process.
Summary of the invention
This utility model purpose is to provide a kind of staircase prefabricated reinforced concrete fire barrier structure and construction thereof, solves the problem that the current high residential building shears prefabricated fire barrier cost of ladder is high, easy to crack.
In order to realize above-mentioned task, the present invention uses following technical solution: a kind of staircase prefabricated reinforced concrete fire barrier structure, described structure is made up of prefabricated reinforced concrete fire barrier, precast concrete stair, staircase half space beam and connector；Both sides, described prefabricated reinforced concrete fire barrier top have dividing plate to choose ear, and dividing plate is chosen in ear and is covered with one layer and chooses ear reinforcing bar, and described prefabricated reinforced concrete fire barrier is chosen ear-hang by the dividing plate of both sides and is located at the end face of staircase half space beam；Prefabricated reinforced concrete fire barrier is connected by connector and described precast concrete stair are fixing.
Further, it is embedded with dividing plate built-in fitting, built-in hanger and demoulding hanging piece in described prefabricated reinforced concrete fire barrier, and is covered with one layer of dividing plate reinforcing bar.
Further, it is embedded with stair built-in fitting in described precast concrete stair.
Further, the dividing plate built-in fitting in described prefabricated reinforced concrete fire barrier is the most corresponding with the stair built-in fitting position in the horizontal and vertical directions in described precast concrete stair.
Further, described connector is angle cleat, and angle cleat is connected with described precast concrete stair bolt.
Further, the concrete material of described prefabricated reinforced concrete fire barrier can be normal concrete, haydite concrete or air entrained concrete.
The invention also discloses the construction of a kind of prefabricated reinforced concrete fire barrier structure, comprise the steps:
Step one, pour or lift staircase half space beam；
Precast concrete stair inside step 2, lifting；
Step 3, hoisting prefabricated reinforced concrete fireproof dividing plate；
Step 4, with connector prefabricated reinforced concrete fire barrier is bolted with inner side precast concrete stair together with and adjust position and the perpendicularity of prefabricated reinforced concrete fire barrier；
Precast concrete stair outside step 5, lifting；
Step 6, prefabricated reinforced concrete fire barrier is bolted with outside precast concrete stair with connector together with；
Step 7, last, plate seam grouting also performs fireproof blocking.
Compared with prior art, technical advantage of the present utility model specifically has the following aspects:
1, using the mode hung to install armored concrete fire barrier, structural stability is good, and power transmission is clear and definite, decreases reinforcing bar and the concrete amount of precast stair, and macroeconomic is good；
2, profile is simple, and available common wallboard production line efficiently produces, easy to make, low cost；Need not plaster in precast concrete surface, decrease situ wet operation, reduce cost；
3, lightweight concrete can be used to make, from heavy and light, easy for installation.Lightweight concrete can be used to make, from heavy and light, easy for installation, it is suitably applied design and the construction of the high residential building shears prefabricated fire barrier of ladder.
The staircase prefabricated reinforced concrete fire barrier structure of the present invention, have employed the hang that power transmission is succinct, has from heavy and light, construct convenient, structure, decoration integrated advantage, it is adaptable to the fire barrier of high residential building precast concrete shears ladder.
