Abstract
The invention discloses a kind of bridge beam slabs to lift spacer bar accurate placement technology, including spacer bar, drum, and the drum is hollow barrel, and the drum does not include top and bottom；The spacer bar accurate placement technology is the following steps are included: S1: drum being placed at position fixed required for spacer bar；S2: the casting concrete in drum pours and fills up drum；S3: filling up drum to concrete, reinforcing bar be inserted into the concrete of drum rapidly, and the reinforcing bar insertion position is required pinpoint position；This technology pours the technology for accurately installing spacer bar afterwards, spacer bar effectively can accurately be arranged, can smoothly lift and install beam slab using embedded sleeve barrel positioning when pouring.
Description
Technical field
The invention belongs to science of bridge building fields more particularly to bridge beam slab to lift spacer bar accurate placement technology.
Background technique
Traditional beam slab spacer bar is welded on steel mesh before pouring cushion cap and bent cap, due to the meeting in casting process
Deviation occurs, reinforcing bar and beam slab position when lifting is caused to be collided.It is positioned using embedded sleeve barrel when pouring, it is fixed accurately to install after pouring
The technology of position reinforcing bar, effectively can accurately be arranged spacer bar, install beam slab smoothly to lift.
Application No. is CN201621299559.X, the applyings date are as follows: 20161130, a kind of title are as follows: bridge beam slab lifting
Spacer bar accurate placement technology.Whether the accuracy of spacer bar position, beam slab can be allowed in hoisting process by being related to beam slab
Installation is gone on smoothly.It can be seen that spacer bar positioning action in science of bridge building is critically important, position cheaply can largely influence
The quality and safety of science of bridge building.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of bridge beam slabs to lift
Spacer bar accurate placement technology.
Purpose of the invention can be achieved through the following technical solutions:
A kind of bridge beam slab lifts spacer bar accurate placement technology, including spacer bar 1, drum 2, the drum 2 are
Hollow barrel, the drum 2 does not include top and bottom；
The spacer bar accurate placement technology the following steps are included:
S1: drum 2 is placed at position fixed required for spacer bar；
S2: the casting concrete in drum 2 pours and fills up drum 2；
S3: filling up drum 2 to concrete, and reinforcing bar 1 is inserted into the concrete of drum 2 rapidly, and the reinforcing bar 1 is inserted into position
Pinpoint position required for being set to.
Preferably, the drum 2 is steel cylinder.
Preferably, 2 internal diameter of drum is 5 centimetres.
Preferably, the 2 ladle body height of drum is 15 centimetres.
Preferably, the depth that the reinforcing bar 1 is inserted into drum 2 is not less than 2/3rds of ladle body height.
Beneficial effects of the present invention:
It is positioned using embedded sleeve barrel when pouring, pours the technology for accurately installing spacer bar afterwards, effectively can be accurately arranged
Spacer bar is not in that deviation can occur in casting process, causes reinforcing bar and beam slab position when lifting to be collided, can smoothly hang
Dress installs beam slab.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that bridge beam slab lifts spacer bar accurate placement technology.
In figure: 1- spacer bar；2- drum.
Specific embodiment
In conjunction with shown in attached drawing, technical solution of the present invention is further described:
A kind of bridge beam slab lifts spacer bar accurate placement technology, including spacer bar 1, drum 2, the drum 2 are
Hollow barrel, the drum 2 does not include top and bottom；
The spacer bar accurate placement technology the following steps are included:
S1: drum 2 is placed at position fixed required for spacer bar；
S2: the casting concrete in drum 2 pours and fills up drum 2；
S3: filling up drum 2 to concrete, and reinforcing bar 1 is inserted into the concrete of drum 2 rapidly, and the reinforcing bar 1 is inserted into position
Pinpoint position required for being set to.
In the present embodiment, preferred selection 2 internal diameter of drum is 5-10 centimetres, and 2 ladle body height of drum is 15 centimetres, states reinforcing bar
The depth of 1 insertion drum 2 is not less than ladle body height.
In the present embodiment, preferred selection reinforcing bar length is 25-30 centimetres.
Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of the present invention, although reference
Above-described embodiment describes the invention in detail, those skilled in the art should understand that: it still can be to this hair
Bright to be modified or replaced equivalently, without departing from the spirit and scope of the present invention, and appended claims are intended to fall into
These modifications or equivalent replacement in spirit and scope of the invention.
