Detailed Description
The following description is of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, but is intended to cover any modifications, equivalents, improvements, etc. within the spirit and principles of the present invention.
1-3, Including riser rectangle frame 2 (i.e. the rectangle frame that comprises vertical setting's panel), slant reinforcing bar 4, rectangle steel sheet 3, consolidate rectangle frame 5, protection network jack, the top of riser rectangle frame 2 coaxial be equipped with rectangle steel sheet 3, the edge of rectangle steel sheet 3 and the side one-to-one of riser rectangle frame 2, the welding has a plurality of slant reinforcing bar 4 between the edge of rectangle steel sheet 3 and the side of riser rectangle frame 2, rectangle steel sheet 3, slant reinforcing bar 4, riser rectangle frame 2 constitute the rectangular pyramid structure, along the coaxial a plurality of reinforcement rectangle frames 5 that are equipped with of level on the rectangular pyramid structure, the side and slant reinforcing bar 4 welding of reinforcement rectangle frame 5, riser rectangle frame 2 be equipped with protection network jack.
As shown in fig. 1-3, the outer surface of the bottom of the vertical plate rectangular frame 2 is integrally formed with an outwards turned horizontal plate rectangular frame 1 (i.e. the plates forming the rectangular frame are horizontal), and a plurality of connecting holes are uniformly distributed on the horizontal plate rectangular frame 1, as shown in fig. 2, and are fixedly connected with the floor slab through expansion bolts penetrating through the connecting holes.
As shown in fig. 1-3, the oblique steel bars 4 are uniformly distributed, and a plugboard opening 8 is formed between the adjacent oblique steel bars 4 and the welding points of the vertical rectangular frame 2 or between the adjacent oblique steel bars and the welding points of the reinforced rectangular frame 5, and a space for inserting a protection plate 9 is formed between the two opposite plugboard openings 8. As shown in fig. 2, when the protection level is high or the hole is required to be completely closed, the protection plates can be respectively inserted into the opposite plugboard openings and fixed (such as holes are formed in the protection plates and bound with the rectangular frames of the vertical plates or the oblique steel bars through iron wires). Meanwhile, it can be understood that after the protection plate is inserted into the reinforced rectangular frame, the protection capability of the novel type is improved by multiple times (such as protection can be performed by the protection plate when materials or a large number of tools are transported into the building structure). When the protection plate is inserted into only part of the reinforced rectangular frame, the protection can be reinforced for the local space of the hole.
