Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated T-beams, in particular to a convenient maintenance bracket for prefabricated T-beams. Background Art

[0002] During the construction of prefabricated prestressed concrete T-beams (referred to as prefabricated T-beams), prefabricated T-beams are generally designed to be high-grade concrete above C50, and prestressed construction can only be carried out when the strength reaches 85%. After the T-beams are prefabricated, reliable concrete maintenance must be carried out to ensure the construction quality. The maintenance of prefabricated T-beams mainly includes winter insulation maintenance, summer sunshade maintenance, and water spray maintenance. The traditional winter insulation maintenance and summer sunshade maintenance require the erection of maintenance brackets for carrying insulation cloth or sunshade nets. The traditional method of erecting maintenance brackets is to manually erect and assemble brackets on site, which is time-consuming and labor-intensive. When it needs to be moved to the next workstation, it is difficult to move the whole thing, which seriously affects the construction progress. There are also automated spray maintenance systems in the prior art, but they are suitable for the maintenance of large prefabricated T-beams. For small and medium-sized prefabricated T-beams, their use cost is relatively high and they are not very suitable. Summary of the invention

[0006] During maintenance, the maintenance bracket is set outside the prefabricated T-beam, the maintenance bracket is unfolded, and three spray pipes with spray nozzles evenly distributed on them are prepared. The three spray pipes are respectively tied to the vertical bars on both sides of the maintenance bracket and the horizontal bar on the top, and the three spray pipes are connected to the main water pipe on the construction site through a four-way joint to achieve water spray maintenance, without the need for manual water spraying, which saves trouble and labor; at the same time, during winter heat preservation maintenance, prepare a piece of insulation cloth, wrap the insulation cloth around the outer periphery of the maintenance bracket, which plays the role of winter heat preservation maintenance, and during summer sunshade maintenance, prepare a sunshade net, and cover the sunshade net on the top surface of the maintenance bracket, which plays the role of summer sunshade maintenance. After the maintenance is completed, the spray pipe is removed, the maintenance bracket is folded and contracted by the telescopic scissors frame, and then the maintenance bracket is moved to the next maintenance station.

[0007] Furthermore, each telescopic scissors frame includes two scissor rods hinged to each other and the hinge axes are arranged along the width direction of the prefabricated T-beam, the top end of each scissor rod is hinged to the top end of the corresponding vertical rod and the hinge axes are arranged along the width direction of the prefabricated T-beam, the bottom end of each scissor rod is hinged to the bottom end of the corresponding vertical rod and the hinge axes are arranged along the width direction of the prefabricated T-beam, and the bottom end of each scissor rod is slidably connected to the corresponding vertical rod up and down.

[0008] Furthermore, the two scissor rods hinged to the top end of the same vertical rod are coaxial with the hinge axis of the vertical rod, and the two scissor rods hinged to the bottom end of the same vertical rod are coaxial with the hinge axis of the vertical rod, so the structure is standardized, more stable, and more convenient to fold.

[0009] Furthermore, the bottom end of each vertical rod is provided with a sliding ring for upward and downward sliding sliding. The hinge shaft at which the bottom end of each scissors rod is hinged to the bottom end of the vertical rod is fixedly connected to the corresponding sliding ring, thereby realizing an upward and downward sliding connection between the bottom end of each scissors rod and the corresponding vertical rod. The structure is simple, easy to implement and low in cost.

[0010] Furthermore, each gantry bracket also includes an arch rod, which is located above the cross rod and has two ends of which are fixedly connected to the top ends of the corresponding two vertical rods, so that the structure is more stable and convenient for drainage on rainy days.

[0011] Furthermore, each portal bracket also includes a reinforcing rod, which is arranged vertically and has two ends respectively connected to the middle of the corresponding arch rod and the middle of the corresponding cross rod, thereby improving the stability of the maintenance bracket.

[0012] Furthermore, the bottom ends of the two vertical rods of each door type are equipped with universal wheels, which makes movement more convenient and further improves construction efficiency.

[0013] Furthermore, each vertical rod is a galvanized steel pipe, and the cross rod, arch rod, reinforcement rod and scissor rod are all flat tubes.

[0014] The beneficial effects produced by the utility model are as follows: the maintenance bracket of the prefabricated T-beam in the utility model can be prepared in advance and reused, does not need to be erected on site, and is easy to move and carry, effectively improving construction efficiency and reducing construction costs.
