Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.

As shown in fig. 1-2, the flue opening edge-facing protection device provided by the present embodiment is used for protecting a flue opening. The flue opening is reserved at one corner edge of the floor 100 and is positioned at the position of the prefabricated plate 200 with the corner structure. The flue opening 4 is of a rectangular structure.

The flue port edge-facing protection device comprises a supporting structure 1, a protection structure 2 and an inner support rod 3.

The supporting structure 1 is an L-shaped structure and is arranged on the side edge of the flue opening 4 positioned on the floor slab 100, the supporting structure 1 and two adjacent prefabricated wall boards 200 form a square structure, the supporting structure 1 is arranged along the floor slab 100 in an upward vertical extending mode, the height of the vertical extending mode is 40 mm-60 mm, preferably 50mm, the supporting structure 1 is a concrete strip integrally formed with the flue opening 4, and the cross section of the concrete strip is a rectangular structure.

The protective structure 2 and the supporting structure 1 are split. The protective structure 2 comprises a cover plate 21 and an abutting part 22, wherein the cover plate 21 covers the upper part of the flue port, and the overall dimension of the protective structure is larger than the rectangular geometric (square) dimension formed by the supporting structure 1. The apron 21 is the steel sheet of 3mm thickness, the quantity of butt piece 22 is two, be right angle welding in the lower terminal surface of apron 21, two butt pieces 22 are close to two adjacent border settings of apron 21.

The abutment member 22 is an angle iron of 30 × 3 (unit: mm) in size, one folded edge of which is welded to the cover plate 21 and the other folded edge extends perpendicularly from the cover plate 21. The folding direction of the two angle irons faces outwards (the outer side refers to the direction far away from the center of the cover plate). When the cover plate 21 is covered above the flue opening, two edges of each angle iron of the two abutting pieces 22 are respectively attached to the upper top surface 11 and the inner side surface 12 of the supporting structure 1. After the cover plate 21 is closed, it abuts against the prefabricated wall panel 200 at the other two edges away from the abutting pieces 22. Therefore, a structure which is expanded outwards is formed in the flue opening 4, a better protection effect is achieved, and the cover plate 21 on the flue opening 4 is prevented from moving.

Interior vaulting pole 3 is the reinforcing bar that the diameter is 12mm, and the quantity can set up to two, follows the width direction interval of flue mouth 4 is arranged, and with the length direction of flue mouth 4 is parallel. One end of the inner support rod 3 is embedded in the supporting structure 1, and the other end extends horizontally into the flue opening 4 and is abutted against the prefabricated wall board 200.

On locating supporting construction 1 with apron 21 lid, the butt 22 and the laminating of supporting construction 1 of angle bar structure, and apron 21 side of keeping away from butt 22 forms the limit protection that faces of flue mouth with the structure of prefabricated wallboard butt, and the angle bar is fine with the concrete strip the removal space of apron 21 that has restricted, and the apron is difficult for removing in the work progress, protects the entrance to a cave well.

Adopt foretell assembly type building floor flue mouth to face limit protection, improved the construction safety in the work progress, face limit protection form more stable, reduce because of the entrance to a cave lacks the probability that the safety in construction appears protecting, protective material ability reuse, protective material transports the convenience.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
