Description
Technical Field
The invention belongs to the technical field of protective construction of light holes of cast-in-place box girders, and particularly relates to an installation and construction method of a safety protection device with light holes in a landscape bridge on a construction site.
Background
In recent years, with the rapid development of the building industry, the urban bridge has higher and higher requirements on landscape, and the bridge bottom hole type light transmission is mostly adopted in the design, so that the bridge has the characteristic of attractive appearance, and accords with the aesthetic design of the bridge. Because the bridge section changes differently, the deviation is larger when the traditional mode is adopted to install and pre-embed the light transmission hole safety protection device, the condition that the device cannot be installed is easy to occur, the traditional vacancy safety protection is less, the adopted form is not attractive, and the material is easy to age and damage.
Disclosure of Invention
The invention provides an installation and construction method of a light-transmitting hole safety protection device.
According to one aspect of the embodiment of the invention, the installation and construction method of the light hole safety protection device comprises the following steps:
and 6, detachably fastening the reinforcing mesh on the gasket.
In some examples, the steel skeleton is a hexagonal star, and six corners of the steel skeleton of the hexagonal star are welded with the embedded steel plate.
In some examples, the steel skeleton, the washer and the steel mesh are made of stainless steel.
In some examples, the steel skeleton is formed by welding a plurality of stainless steel rod pieces through full welding.
In some examples, the washer and the embedded steel plate are welded in a single-side mode.
In some examples, the weld locations are sprayed with a non-fingerprint coating.

Detailed Description
Referring to fig. 1-4, a method for installing a light hole safety device is described as follows.
And 3, performing concrete pouring operation, pouring one side of the embedded steel plate 3 firstly during pouring, ensuring the position to be compact, preventing later-stage cracking and water seepage, dismantling the nuts of the first embedded bolt 1 and the second embedded bolt 2 after initial setting of concrete, and maintaining the screw thread position in a clean and wet mode.
And 4, assembling the steel skeleton 5, cutting stainless steel rod pieces required by the steel skeleton 5 according to data actually measured on site, and assembling the stainless steel rod pieces into the steel skeleton 5 in a welding mode (all the stainless steel rod pieces are welded in a full welding mode). The steel skeleton 5 may be a hexagonal star shape. And then welding six corners of the hexagonal star-shaped steel skeleton 5 with the embedded steel plate 3. After all welding is finished, in order to prevent the stainless steel surface from being damaged and oxidized, a non-fingerprint coating is sprayed at the welding position to protect the steel skeleton 5.
And 5, after the steel skeleton 5 is installed, installing a stainless steel gasket 6, welding (single-side welding) the stainless steel gasket 6 and the embedded steel plate 3, protecting an installation bolt hole 7 on the stainless steel gasket 6 by welding attention, spraying the welding seam position without fingerprints after welding is completed, keeping for at least 4 hours after coating spraying, and then performing surface construction to ensure that the coating is not damaged.
And 6, placing the reinforcing mesh 8 on the stainless steel washer 6, adjusting the reinforcing mesh 8 to be just centered, aligning to the hole position of the mounting bolt, fixing the reinforcing mesh 8 on the stainless steel washer 6 through the bolt 9, and completing the mounting of the whole light hole protection device.
The invention solves the problems of installation of the safety protection device and safety and stability of the device after installation by utilizing the upper row of first embedded bolts 1 and the lower row of second embedded bolts 2. The steel skeleton 5 is fixed by the embedded steel plate 3, so that the problem of stable installation is solved. The installation problem of the reinforcing mesh piece 8 is solved through the stainless steel gasket 6. Utilize the construction bolt to fasten the reinforcing bar net piece 8 on the stainless steel gasket 6, guarantee the firm of reinforcing bar net piece 8. The steel skeleton 5 in the shape of a hexagon star is attractive in appearance, the stability of the protection device is guaranteed, and the dead weight of the protection device in the traditional method is reduced. The steel skeleton 5, the gasket 6 and the steel bar net piece 8 are made of stainless steel materials to improve the durability of the protection device. The reinforcing mesh 8 is fastened on the gasket 6 by bolts, so that the reinforcing mesh 8 can be detached, and the problem of maintenance and replacement of brightening illumination is solved. Namely, the invention solves the technical problem of installation and construction of the safety protection device with the light holes in the landscape bridge on the construction site.
