As shown in fig. 1: fig. 1 is a truss rib structure diagram in the prior art, in some prefabricated parts, only two lower main ribs 1 at the lower end of three straightened steel bars need to be pre-buried in a construction member, and an upper main rib 2 is used for secondary pouring. In order to ensure that the concrete can be fully contacted with the upper main rib 2 during secondary pouring and enhance the connection tightness between the two, the concrete needs to be ensured not to be adhered to the upper main rib 2 during the first pouring process. In view of the above, this embodiment discloses a truss rib sheath for a PC member, including two clamping plates 4, two ends of the clamping plates 4 are respectively provided with a holding end 41 and a clamping end 42, a hinge part 6 is further provided between the holding ends 41 and the clamping ends 42 of the clamping plates 4, the hinge parts 6 of the two clamping plates 4 are connected, and an elastic device for driving the two clamping ends 42 to press each other is further provided between the two clamping plates 4; the clamping end 42 is further provided with a clamping assembly, the clamping assembly comprises a rubber layer 5 and a hairbrush 8 which are connected to the end part of the clamping end 42, the rubber layer 5 and the hairbrush 8 are respectively detachably connected to the inner surface and the outer surface of the clamping end 42, and the length of the hairbrush 8 is larger than the width of the rubber layer 5.
The rubber layer 5 is connected with the clamping end 42 in the following manner: an inner pressure plate 51 is provided on the inner surface of the clamping end 42, and a rubber layer 5 is provided between the clamping end 42 and the inner pressure plate 51, the inner pressure plate 51 being connected to the clamping end 42 by screws 9.
The brush 8 is connected with the clamping end 42 in the following manner: the outer surface of the clamping end 42 is provided with an outer pressing plate 81, the hairbrush 8 is arranged between the outer pressing plate 81 and the clamping end 42, and the outer pressing plate 81 is connected to the clamping end 42 through a screw 9.
The screw 9 is further connected to a nut 91 by means of threads, the nut 91 preferably being a wing nut which can be easily rotated manually. When the brush 8 and the rubber layer 5 need to be replaced, the outer pressure plate 81 and the inner pressure plate 51 can be released.
The clamping end 42 is further provided with a limiting protrusion 421, and the limiting protrusion 421 is connected with the ends of the inner pressing plate 51 and the outer pressing plate 81, and is used for preventing the inner pressing plate 51 and the outer pressing plate 81 from sliding, and is also beneficial to positioning the inner pressing plate 51 and the outer pressing plate 81 during installation.
Specifically, the two hinge parts 6 are connected through the middle plate 7, the two hinge parts 6 are hinged to the middle plate 7 through a central shaft, the end parts of the hinge parts 6 are further provided with fan-shaped ends 61, the outer side parts of the fan-shaped ends 61 are provided with gears 62, the gears 62 of the two fan-shaped ends 61 are kneaded, the middle plate 7 is further connected with a magnet 73, and the magnet 73 is used for connecting the upper main rib 2.
Specifically, the intermediate plate 7 is connected to the magnet 73 via the intermediate lever 71 and the magnet holder 72 in this order.
The upper main rib 2 connecting surface of the magnet 73 is also provided with a chute parallel to the axis of the upper main rib 2. The diagonal grooves can increase the contact area between the magnet 73 and the upper main rib 2, and increase the magnetism therebetween.
Specifically, the elastic device is a spring 43, two ends of the spring 43 are respectively connected with two handheld ends 41, a spring connecting surface of the handheld ends 41 is also provided with a positioning protrusion 411, and the positioning protrusion 411 is connected with the end of the spring 43 and is used for positioning the spring 43.
When in use, when two holding ends 41 are pressed to open two holding ends 42, the holding ends 42 can be held on the upper main rib 2, and the hairbrush 8 is softer and has larger flexibility, and the length of the hairbrush 8 is larger than the width of the rubber layer 5, so that when the rubber layer 5 is contacted with the chord steel bar 3, the hairbrush 8 can penetrate the chord steel bar 3 to play a certain protection role on the chord steel bar 3, and the holding plates 4 on two sides can play a protection role to prevent concrete from being stained on the upper main rib 2.
Although the chord steel bar 3 and the rubber layer 5 have a certain friction force, the chord steel bar 3 and the rubber layer 5 can be fixed by the friction force, the interface of the truss steel bar is triangular, so that the clamping end 42 may slide up the main steel bar 2 in actual use, and the service efficiency of the truss steel bar is reduced. For this reason, the present embodiment further includes a magnet 73 provided in the hinge portion 6, and the magnet 73 is magnetically connected to the upper main bar 2 to fix the distance between the hinge portion 6 and the upper main bar 2.

According to the invention, a certain protection function can be achieved on the upper main rib 2, the hairbrush 8 can effectively shield the upper main rib 2, meanwhile, as the hairbrush 8 is larger in flexibility, softer in material and of a dispersion structure, concrete is not easy to adhere to the hairbrush 8, the length of the embodiment can be designed according to actual requirements in actual use, and a plurality of embodiments can be connected in series for use when the truss rib is longer. The embodiment provides a reasonable solution for the protection of the upper main bar 2 in the truss bar in the prior art, when the chord bar 3 is clamped, upward sliding can be avoided, and inclination between the upper main bar and a horizontal plane (the horizontal plane where the two lower main bars 1 are positioned) can be avoided in the clamping process.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present invention, and such modifications and variations should also be regarded as being within the scope of the invention.
