[0014] In the drawing: 1, fixed ring, 2, reinforcing support rod, 3, rotating groove, 4, sliding groove, 5, sliding block, 6, adjusting rod, 7, support plate, 8, protective pad, 9, threaded sleeve, 10, threaded rod, 11, rotating block. CONCRETE IMPLEMENTING METHOD

[0015] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model protection.

[0016] Please refer to Figures 1-2 The utility model provides a kind of technical scheme: a bridge hollow slab inner mould support device, including fixed ring 1, the surface of fixed ring 1 is fixed and is provided with rotating groove 3, the inner side of rotating groove 3 is fixed and is provided with sliding groove 4, sliding groove 4 is slidably connected with sliding block 5 in its inside, one end of sliding block 5 is fixedly connected with adjusting rod 6, one end of adjusting rod 6 is fixedly connected with support plate 7.

[0017] In the embodiment, the fixed ring 1 is set as a reference center, and the sliding groove 4 is set in the inner side of the fixed ring 1. At this time, the sliding block 5 is slidably connected in the sliding groove 4 as an arc block. The sliding block 5 is connected with the adjusting rod 6 through the fixed block. The fixed block can slide in the rotating groove 3 to adjust the position of the adjusting rod 6, thereby adjusting the supporting angle of the support plate 7. The hollow inner mould of different shapes can be supported. The supporting device adopts a supporting mode that can adjust the angle. The length of the adjusting rod 6 can be adjusted to adapt to the hollow mould of different shapes, so that the supporting performance is better. The device can be repeatedly used, and it is convenient to install and remove, thereby saving a large amount of resources.

[0018] Specifically, the center of the fixed ring 1 is fixedly connected with the reinforcing struts 2, and the number of the reinforcing struts 2 is three.

[0019] In the embodiment, by adopting three reinforcing struts 2, the strength of the fixed ring 1 can be enhanced according to the stability of the triangle, so that the overall support is better.

[0020] Specifically, the adjusting rod 6 comprises a threaded sleeve 9, a threaded rod 10 and a rotating block 11, one end of the threaded sleeve 9 is internally threaded and sleeved with the threaded rod 10, and one end of the threaded rod 10 is fixedly connected with the rotating block 11.

[0021] In the embodiment, when the wrench is used actively, the rotating block 11 can make the threaded rod 10 threadedly expand and contract, so that the overall length of the adjusting rod 6 can be adjusted, and the four adjusting rods 6 can be adjusted differently, so that the hollow mold of different shapes can be supported.

[0022] Specifically, the outer surface of the supporting plate 7 is fixedly connected with the protective pad 8, and the protective pad 8 is made of rubber material.

[0023] In the embodiment, the protective pad 8 can increase the friction between the supporting plate 7 and the inner wall of the mold, and can also play a certain protection role, so as to avoid damaging the inner wall, and the protection effect is good.

[0024] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
