b. concrete chisel hair
The template is arranged on the poured floor of the lower windowsill to connect new and old concrete, so that the floor where the lower windowsill is located is roughened, surface cement is chiseled to expose stones, and the building is washed clean by clear water;
c. building formwork support system
The overhanging floating window plate template support system is erected by adopting a method of integrating a full-hall support frame and a floating window plate overhanging support; the vertical horizontal rods in the overhanging support frame of the up-floating windowsill are required to be connected with at least three upright rods of the full-space support frame, at least three horizontal rods are required to be arranged, the distance between the vertical upright rods is not more than 500mm, all upright rods/cross rods/inclined supports are required to be fastened by fasteners, and the torque force of the fasteners is not less than 40N/M; the overhanging support frame of the lower floating windowsill is independently erected on the poured lower floating windowsill plate;
d. form reinforcement
After the template support system is erected, the wood beam and the gluing template are adopted to mount and reinforce the bottom die and the side die of the bay window plate firmly.
e. Pouring of concrete
After the formwork is installed, the formwork and a floor concrete structure are poured synchronously, the vibration is dense, and the operation personnel should be prevented from trampling on the overhanging window board for construction in the pouring process.
The construction method of the cast-in-situ overhanging floating window plate can be further realized by adopting the following technical measures.
In the method, an oblique supporting rod of the overhanging support frame of the bay window sill has an oblique angle greater than 45 ° with the floor.
The method of the foregoing, wherein the downer sill concrete strength should be at least 75%.
The method, wherein the distance between the vertical support rods of the floating windowsill overhanging support frame is not more than 500 mm.
After the technical scheme is adopted, the construction method of the cast-in-situ overhanging floating window plate has the following advantages:
1. the construction of the overhanging floating window plate is synchronous with the main structure, so that the construction cost of a secondary structure is saved;
2. the engineering quality is safe and reliable, and the structural quality is better guaranteed;
3. the construction efficiency is improved, and the engineering cost is reduced.
Drawings
FIG. 1 is a schematic view of an overhanging louver template support architecture according to an embodiment of the present invention.
Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example 1
The construction method of the cast-in-situ overhanging floating window plate comprises the following steps:
(1) measuring line
And ejecting a plane position line and an elevation control line of the windowsill according to the requirement of a design drawing.
(2) Concrete chisel hair
Because the template is installed on the poured floor of the lower windowsill to connect new and old concrete, the floor where the lower windowsill is located is roughened, surface cement is chiseled to expose stones, and the building is washed clean by clear water.
(3) Building formwork support system
Referring now to fig. 1, fig. 1 is a schematic structural diagram of a cantilever bay window board template support system according to an embodiment of the present invention, including a to-be-cast floor 2, a lower bay windowsill 7, and a cast floor 8. As shown in the figure, encorbelmenting and wafting luffer boards template support system adopts full hall support frame and the integrated method of encorbelmenting and supporting of luffer boards to set up, and the windowsill 4 that wafts on should satisfy following setting up requirement:
1) the longitudinal horizontal rod is connected with at least three full-space support frame upright rods 1;
2) at least three transverse horizontal rods 3 are arranged;
3) the distance between the vertical upright rods 6 is not more than 500 mm;
4) the oblique angle between the oblique supporting rod 5 and the floor is more than 45 degrees;
5) all upright rods/cross rods/inclined supports are fastened by fasteners, and the torsion of the fasteners is not less than 40N/M;
the lower windowsill support frame is independently erected on the poured upper windowsill plate and meets the following erection requirements;
1) the strength of the cast upper windowsill cantilever slab concrete is at least 75%; if the strength is not enough, the lower support of the cantilever plate cannot be detached.
2) The distance between the vertical support rods is not more than 500 mm;
(4) form reinforcement
