Technical field:
the utility model belongs to the field of bridge construction, and particularly relates to a pile foundation orifice edge protection device.
The background technology is as follows:
in recent years, when the reinforcement cage is in butt joint installation and concrete pouring construction in the construction process of a drilling pile foundation, construction teams can construct by means of an auxiliary tool such as a pile foundation orifice chuck (base), and as the construction conditions, the construction method, the construction habit and the like are different, the processed orifice chucks are different in material and shape, and the common rectangular inner octagonal orifice chucks with large-rigidity square steel in welding processing are basically the same in use method, the reinforcement cage is only required to be horizontally placed on a sleeper of the pile foundation orifice when in use, the reinforcement cage is supported on the orifice chucks by means of inserting steel pipes and the like, and auxiliary workers are in butt joint installation of the reinforcement cage and pouring concrete; in the existing pile foundation construction process, the edge protection measures are not established at the pile foundation orifice, on-site workers are exposed to dangerous occasions frequently when butt joint the reinforcement cage and use the sounding pipe in the construction site, and orifice operation volume is large, so that accidents that constructors fall into a drilled hole from the orifice easily occur, and the safety risk of construction operation is large.
The utility model comprises the following steps:
the utility model aims to provide a pile foundation orifice edge protection device, overcomes the defects of the prior art, and effectively solves the existing problems of construction safety protection.
The utility model comprises the following steps: the utility model provides a pile foundation drill way limb protection device, includes the frame base offer on the frame base and fill the mouth set up main protection rail directly over the filling mouth main protection rail with the roof of frame base is connected through the bracing piece set up scalable pair protection component in the main protection rail.
Further, the telescopic auxiliary protection assembly comprises an auxiliary protection fence, the auxiliary protection fence is fixedly connected with the upright rod through a supporting arm, a blind groove is formed in the supporting rod, and the upright rod slides in the blind groove.
Further, a screw hole is formed in the side wall of the supporting arm, the screw hole is communicated with the blind groove, a bolt is screwed into the screw hole, and the bolt is used for propping up the vertical rod.
Further, the bolts are claw bolts.
Further, a blind hole is formed in the top wall of the frame base vertically downwards, and the bottom end of the supporting rod is inserted into the blind hole.
Further, the main guard rail and the auxiliary guard rail are both circular.
Further, the main protective fence and the auxiliary protective fence are respectively provided with a light reflecting strip.
Further, a lifting lug is mounted on the frame base.
The utility model has the beneficial effects that: through the dual arrangement of the main protective fence and the auxiliary protective fence, effective safety protection to different construction stages of pile foundation orifices is effectively realized, the situation that site constructors fall into holes is avoided, and the safety risk of construction operation is reduced.

FIG. 1 is a front view of the present utility model;
FIG. 2 is a top view of the present utility model;
FIG. 3 is an enlarged view of portion A of FIG. 2;
FIG. 4 is a view showing the structure of the support bar and the upright of the present utility model;
in the figure, 1 frame base, 2 filling port, 3 main protection rail, 4 bracing pieces, 5 vice protection rail, 6 pole setting, 7 support arm, 8 bolts, 9 blind holes, 10 lug.
The specific embodiment is as follows:
for a clearer understanding of technical features, objects, and effects of the present utility model, a specific embodiment of the present utility model will be described with reference to the accompanying drawings:
as shown in fig. 1 to 3, a pile foundation orifice edge protection device comprises a frame base 1, a filling opening 2 is formed in the frame base 1, a main protection fence 3 is arranged right above the filling opening 2, the main protection fence 3 is connected with the top wall of the frame base 1 through a supporting rod 4, a telescopic auxiliary protection assembly is arranged in the main protection fence 3, and the telescopic auxiliary protection assembly comprises: the auxiliary protective fence 5, auxiliary protective fence 5 passes through support arm 7 fixed connection with pole setting 6 set up blind groove on the bracing piece 4, pole setting 6 is in the slip of blind inslot the screw has been seted up to the lateral wall of support arm 7, the screw with blind groove is linked together the spiro union has bolt 8 in the screw, bolt 8 is used for the top to tighten pole setting 6, bolt 8 is the claw bolt.
Specifically, the edge protection of pile foundation holes is realized through the main protection fence 3, and the constructor is prevented from falling.
In the actual use process, the protection state is divided into two types, the first is full protection: firstly, placing a frame base 1 at a pile foundation orifice, at the moment, installing a main protection fence 3 on the frame base 1, then extracting a vertical rod 6 from a blind groove formed in a support rod 4, lifting an auxiliary protection fence 5 from an inner cavity where the main protection fence 3 is positioned, tightly propping the vertical rod 6 by a bolt 8 to prevent displacement, expanding the protection area of the auxiliary protection fence 5 under the protection of the main protection fence 3, and at the moment, carrying out the hoisting operation of a head-connection reinforcement cage; the second is semi-protection: when two sections of steel reinforcement cages are fixedly butted up and down, the bolts 8 are loosened, the vertical rods 6 are inserted into the blind grooves, the auxiliary protective fence 5 descends into the inner cavity where the main protective fence 3 is located, only the main protective fence 3 is in a protective state at the moment, due to the reduction of the protective height, the on-site constructors can conveniently and rapidly dock and fix two sections of steel reinforcement, time and labor are saved, and the protective device is restored to a full-protective state after docking is completed.
As shown in fig. 1 to 3, a blind hole 9 is formed in the top wall of the frame base 1 vertically and downwards, the bottom end of the supporting rod 4 is inserted into the blind hole 9, the main protective fence 3 and the auxiliary protective fence 5 are all round, reflective strips are arranged on the main protective fence 3 and the auxiliary protective fence 5, and lifting lugs 10 are mounted on the frame base 1.
In particular, the support rod 4 is inserted into the blind hole 9, facilitating its quick installation.
In the actual use process, the support rod 4 is inserted into the blind hole 9 formed in the frame base 1, so that the protection device can be conveniently and rapidly installed and disassembled before and after construction, and time and labor are saved; the reflective strips are helpful for marking and warning the protective device during construction at night.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
