Description

Construction method for erecting side template of roof post-cast strip
Technical Field
The invention belongs to the installation of a floor post-cast strip template, and particularly relates to a construction method for erecting a roof post-cast strip side template.
Background
At present, post-cast strips are required to be arranged on buildings with the designed length of more than 40m, and formwork is required to be erected when the post-cast strips are subjected to concrete pouring. But the steel bars pass through the side surface of the position, so that the formwork cannot be arranged. Among the prior art can only set up the multilayer flitch side by side in the post-cast strip side, the flitch lets out lower floor's reinforcing bar and upper reinforcing bar position, consequently forms to close to enclosing of post-cast strip and has very big gap, leaks the thick liquid seriously, causes the material extravagant, pollutes other structures, and post-cast strip side later stage needs to be maintained.
Disclosure of Invention
The invention aims to solve the technical problem that the existing floor post-cast strip cannot be used for formwork support.
The technical scheme provided by the invention for solving the technical problems is as follows:
a construction method for erecting a side template of a post-cast strip of a roof slab comprises the following steps:
1) slotting a multilayer board with the thickness of 15mm according to the steel bar spacing of a floor slab post-cast strip to manufacture a lower comb board, wherein the slotting depth is equal to the height from a first layer of steel bars to the bottom surface of the structure, and the height of the lower comb board is equal to the height from a second layer of steel bars to the bottom surface of the structure;
2) the lower comb plate is inserted onto the first layer of steel bars from top to bottom, and each notch corresponds to each steel bar;
3) taking a 15mm thick multilayer board to manufacture an upper-layer comb board, wherein the height of the board is 90mm, slotting is carried out according to the distance between second-layer steel bars, and the slotting depth is 50 mm;
4) the slot of the upper comb plate is inserted corresponding to the second layer of steel bars, and the lower side of the upper comb plate is overlapped with the lower comb plate from the outside and is fixed with the lower comb plate;
5) the included angle between the lower comb plate and the first layer of steel bars is provided with a batten for fixation; and battens are arranged at the included angle between the outer side of the upper comb plate and the second layer of steel bars for fixing.
The invention realizes the formwork support of the side surface of the post-cast strip of the roof slab, the comb plate-shaped formwork effectively increases the concrete contact surface, reduces the concrete leakage, saves the concrete consumption and is convenient to dismantle the formwork.
Drawings
FIG. 1 is a diagram of a comb plate structure provided by the present invention;
fig. 2 is a view showing a structure of a mold installation.
In the figure, a lower comb plate 1, an upper comb plate 2, a notch 3, a second layer of steel bars 4, a first layer of steel bars 5, a post-pouring belt 6, battens 7 and battens 8.
Detailed Description
The following detailed description of the formwork structure and construction process of the present invention is made with reference to the accompanying drawings and specific construction embodiments:
in order to solve the problem of slurry leakage in post-cast strip pouring, the invention provides a template structure for designing a post-cast strip aiming at the actual structure of the post-cast strip, and specifically, the template structure is shown in the following figure 1: a roof slab post-cast strip side template comprises a lower layer plate and an upper layer plate, wherein the height of the lower layer plate is equal to the height of a second layer of steel bars 4 from the bottom surface of a structure, the lower layer plate is a comb plate with notches 3 at the lower part, the notches 3 are arranged according to the distance between the first layer of steel bars 5 of a floor slab post-cast strip 6, the depth of each notch 3 is equal to the height of the first layer of steel bars 5 from the bottom surface of the structure, and the width of each notch 3 is equal to the diameter of the steel; the upper plate is a comb plate with a notch at the lower part, the notch 3 is arranged at the interval of 4 second-layer steel bars in the floor post-cast strip, the height of the upper plate is 90mm, and the depth of the notch is 50 mm.
The invention also provides a floor post-cast strip side formwork erecting construction method based on the formwork structure, which comprises the following specific construction steps:
1) slotting a multilayer board with the thickness of 15mm according to the steel bar spacing of a floor slab post-cast strip to manufacture a lower comb plate 1, wherein the slotting depth is equal to the height from a first layer of steel bars 5 to the bottom surface of the structure, and the height of the lower comb plate 1 is equal to the height from a second layer of steel bars 4 to the bottom surface of the structure;
2) the lower comb plate 1 is inserted onto the first layer of steel bars from top to bottom, and each notch 3 corresponds to each steel bar;
3) taking a multilayer plate with the thickness of 15mm to manufacture an upper-layer comb plate, wherein the height of the plate is 90mm, slotting is carried out according to the 4-pitch interval of the second-layer steel bars, and the slotting depth is 50 mm;
4) the notch of the upper comb plate 2 is inserted corresponding to the second layer of steel bars, and the lower side of the upper comb plate is overlapped with the lower comb plate 1 from the outside and is fixed with the lower comb plate;
5) a batten 7 is arranged at the included angle between the lower comb plate and the first layer of steel bars for fixation; and battens 7 are arranged at the included angle between the outer side of the upper comb plate and the second layer of steel bars for fixing.
