The utility model discloses an adopt the structure at the pre-buried safe edge angle steel in bight, can reduce the concrete support because of colliding with the damage that receives, through scribbling reflection of light paint on the safe edge angle steel, for the earthwork excavation at night provides the warning, can reduce or avoid the concrete support because of colliding with the damage that receives, reflection of light paint still has rust-resistant effect simultaneously. The edge protection angle steel is fixedly connected with a reinforcement arrangement structure of the concrete support through a plurality of spaced support steel bars, and the structure is stable and reliable. Moreover, the utility model has simple structure, convenient manufacture and lower cost.
Description
Technical Field
The utility model relates to a foundation ditch envelope's concrete support, especially a concrete support prevent the safe edge structure that collides with.
Background
In recent years, large-scale construction of underground engineering, particularly underground rail transit facilities, needs to carry out large-area earthwork excavation after the enclosing structure of the underground engineering is finished and before the main structure is constructed, and in the process of earthwork excavation, because the concrete supports of the enclosing structure span a foundation pit and are close to each other, the concrete supports are basically positioned within the operation radius of an excavator. Meanwhile, earthwork operation is carried out at night most of the time, and the excavator often collides the concrete support of the enclosure structure under the condition of poor sight, so that the mechanical property and the appearance quality of the concrete support are influenced.
Disclosure of Invention
The utility model discloses a solve the technical problem that exists among the well-known technology and provide a foundation ditch enclosure structure concrete support prevent the safe edge structure that collides with to reduce, avoid the concrete support because of colliding with the damage that receives.
The utility model discloses a solve the technical scheme that technical problem that exists among the well-known technique took and be: the utility model provides a foundation ditch envelope concrete support prevent safe edge structure of colliding with, includes along the pre-buried safe edge angle steel of concrete support bight full length the safe edge angle steel be equipped with reflection of light paint coating on the surface, the safe edge angle steel welding is on the support reinforcement that a plurality of intervals set up, the support reinforcement welding is on the arrangement of reinforcement structure that the concrete supported.
The edge protection angle steel has the length of 50-80mm and the thickness of 4-6 mm.
The diameter of the supporting steel bar is 12-16mm, and the interval is 500-800 mm.
The utility model has the advantages and positive effects that: through adopting the structure at the pre-buried safe edge angle steel in bight, can reduce the concrete support because of colliding with the damage that receives, through scribbling reflection of light paint on the safe edge angle steel, for the earthwork excavation at night provides the warning, can reduce or avoid the concrete support because of colliding with the damage that receives, reflection of light paint still has rust-resistant effect simultaneously. The edge protection angle steel is fixedly connected with a reinforcement arrangement structure of the concrete support through a plurality of spaced support steel bars, and the structure is stable and reliable. Moreover, the utility model has simple structure, convenient manufacture and lower cost.
Drawings
FIG. 1 is a cross-sectional view of the present invention;
fig. 2 is a plan view of the present invention.
In the figure: 1. a concrete entity; 2. a reinforcement structure; 3. supporting the reinforcing steel bars; 4. and (4) edge protecting angle steel.
Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:
referring to fig. 1 and 2, the anti-collision edge protecting structure for the concrete support of the foundation pit support structure comprises edge protecting angle steel 4 pre-embedded along the whole length of the corner of the concrete support 1, a reflective paint coating is arranged on the surface of the edge protecting angle steel 4, the edge protecting angle steel 4 is welded on a plurality of supporting steel bars 3 arranged at intervals, and the supporting steel bars 3 are welded on a reinforcement structure 2 of the concrete support.
In the embodiment, the side length of the edge-protecting angle iron 4 is recommended to be 50-80mm, and the thickness is recommended to be 4-6 mm. The diameter of the supporting steel bar 3 is 12-16mm, and the interval is 500-800 mm.
The utility model discloses a construction method:
firstly, binding a reinforcement structure 2 supported by concrete, and marking the position of a supporting steel bar 3 by using red paint at an interval of 500-800mm after binding.
And secondly) welding the manufactured support steel bar 3 and the edge protection angle steel section together.
And thirdly) welding the components of the supporting steel bars 3 and the edge-protecting angle steel sections manufactured in the second step with the reinforcement structure 2 according to the positions marked by the red paint on the reinforcement structure 2, butting the edge-protecting angle steel sections on the same corner part, and fully welding the seams.
Fourthly) rechecking the position of the edge-protecting angle steel before erecting the template, and adjusting in time if deviation exists.
Fifthly), concrete pouring is carried out after the templates are erected, concrete near the edge protection angle steel is vibrated by adopting an inserted vibrating spear, uniform pouring is carried out, and the vibrating spear cannot directly contact the edge protection angle steel. And (5) timely removing surface floating slurry during pouring to ensure that the edge-protecting angle steel is exposed.
And sixthly) after the strength of the concrete meets the requirement, removing the template, cleaning the outer surface of the edge-protecting angle steel, and painting black-yellow phase reflective paint on the outer surface of the edge-protecting angle steel to finish the manufacture of the concrete support 1.
Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, which is within the scope of the present invention.
