The utility model aims to provide an operation platform which is favorable for grouting operation for construction operators, so that the grouting operation platform can be safely ensured in the grouting process, and safety accidents are avoided.
In order to achieve the above purpose, the present solution specifically adopts the following technical means:
a protective frame suitable for bridge construction comprises an upper part and a lower part, wherein the upper part is a working platform frame, and the lower part is a built-in part; the upper part is erected above the cover beam and is used for grouting operation protection; the lower part is embedded at the outer side of the cover beam; the upper part and the lower part comprise a plurality of cross bars and vertical bars which are fixed through welding or reinforcing bolts; the upper part of the protective frame is also provided with a falling-preventing plate.
Further, the height of the working platform frame is 1.2m, the length of the embedded part is 1m, and the whole length of the protection frame is 3m.
Furthermore, the protection frames are of symmetrical structures, and the single-side protection frames are connected through cross bars.
Further, the unilateral protection frame comprises a vertical rod and a longitudinal railing connected with the vertical rod.
Further, the unilateral protection frame is connected through 5 cross bars.
Further, the single-side protection frame comprises 3 vertical rods; the number of the single-side handrails is 2, and the single-side handrails are respectively positioned at the top, the middle and the bottom of the protective frame.
Further, the anti-falling plate is arranged on the railing at the bottom.
Preferably, the rod piece of the protection frame is a round steel pipe or a square pipe.
Compared with the prior art, the utility model has the following beneficial effects:
after the protective frame is assembled on site, the protective frame can be easily erected on the capping beam through a crane, the bottom of the vertical rod is anchored on the surface of the beam, and the anti-falling plate is arranged above the edge of the beam to increase the protective area, so that the whole structure is light, convenient and firm. The vertical protective frame can provide safety guarantee for personnel working aloft and improve the safety in the grouting process.

Detailed Description
Other advantages and effects of the present utility model will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present utility model with reference to specific examples. The utility model may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present utility model. It should be noted that the illustrations provided in the following embodiments merely illustrate the basic idea of the present utility model by way of illustration, and the following embodiments and features in the embodiments may be combined with each other without conflict.
Wherein the drawings are for illustrative purposes only and are shown in schematic, non-physical, and not intended to limit the utility model; for the purpose of better illustrating embodiments of the utility model, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the size of the actual product; some well known structures in the drawings and omission of the description thereof will be understood by those skilled in the art.
The scheme provides a protection frame suitable for the cover beam grouting. The fixed height of the protection frame is 2.2m, wherein the height of the operation platform of 1.2m and the embedded length of the bottom of 1m are included, the plane size of the protection frame is determined according to the top surface size of the bent cap, the position of the protection frame is fixed by utilizing the embedded piece, slipping and falling are prevented, and the grouting operation is conveniently carried out by operators at high altitude.
Please refer to a single-sided structure schematic diagram of the protection frame of fig. 1. The upper part operation platform frame is arranged on the cover beam, and the lower part is embedded and fixed on the side part of the cover beam. Comprises 3 vertical rods 2, wherein 1.2m above the vertical rods 2 is the upper part of the protective frame, 1m below the vertical rods are the upper part of the protective frame, and the whole length is 3m. The whole symmetrical structure that is of protection frame, including 3 montants 2 in the unilateral protection frame, the welding has railing 3 between the montant 2, and railing 3 is not only used for connecting montant 2, strengthens overall structure's stability, still plays the effect of protection. The quantity of railing 3 is 3, sets up respectively in the top, middle part and the bottom of protection frame, and railing 3 of bottom is located the bent cap edge. The anti-falling plate 4 is erected on the bottom railing 3, so that the protection area can be increased.
Referring to the side view of the protection frame shown in fig. 2, the vertical rods 2 on two sides of the protection frame can be connected with the cross rod 1 by adopting welding or reinforcing bolts; the two side protection frame structures are connected into a whole through 5 cross bars 1 to form an integral frame structure, so that the protection frame structure is erected on the bent cap. The length of the cross rod 1 is slightly larger than the width of the bent cap, so that the protection frame is just clamped at two sides of the bent cap, and the bent cap is convenient to embed.
After the ground is manufactured, the protective frame is transported to the grouting position of the top surface of the bent cap by the crane, so that the protective frame can be used as a personnel operation protective frame and also can be used for high hanging and low hanging of a safety belt. And after grouting, the grouting material can be recycled, disassembled and reused. The utility model is applied to grouting operation, and avoids high-altitude falling accidents caused by personnel working at high altitude.
