Abstract
The utility model provides a combined hole covering piece used for overcoming the defects of a traditional hole covering mode in existing building construction. The combined hole covering piece comprises a main covering reinforcing mesh piece, an operation hole covering reinforcing mesh piece and pipe-type connecting pieces, wherein the main covering reinforcing mesh piece is a reinforcing mesh piece structural piece in the shape like a Chinese character 'hui', the operation hole covering reinforcing mesh piece is a square reinforcing mesh piece structural piece, each pipe-type connecting piece is a steel sleeve pipe with the inner diameter being larger than 30mm, and the pipe-type connecting pieces are used for movably connecting one edge of the operation hole covering reinforcing mesh piece and one reinforcing steel bar, close to the inner frame of the main covering reinforcing mesh piece, in the main covering reinforcing mesh piece. The combined hole covering piece has the advantages that the combined hole covering piece is used for directly covering the top of a hole of a manual hole digging pile without moving back and forth, the operation hole area is effectively reduced, potential safety hazards are reduced, and the combined hole covering piece is convenient and quick to use.
Description
Technical field
The utility model relates to the realm of building construction, specifically a kind of combined type aperture covering.
Background technology
At present, in building engineering construction, adopt the reinforcing bar of monoblock or plank net sheet to cover the aperture of hand excavated pile.Under each workman, before the operation of hole, all the reinforcing bar of above-mentioned monoblock or plank net sheet must be removed; After completing, the operation on the same day also to again with reinforcing bar or the plank net sheet of monoblock, cover.In addition, in operation process, because reinforcing bar or the plank net sheet of monoblock are removed, does not block in the aperture of hand excavated pile, and safety guarantee is lower; In addition, move repeatedly, cover and make work complicated, loaded down with trivial details, easily occur omitting, produce new potential safety hazard.More special hole, large aperture stakes, its construction safety utmost point is difficult to ensure card.
Utility model content
In order to overcome existing building construction, with traditional aperture, cover existent defect, the utility model provides a kind of combined type aperture covering, and its concrete structure is as follows:
Combined type aperture covering, comprises that main covering reinforced mesh 1, operation hole cover reinforced mesh 2 and cast connector 3; Wherein, main covering reinforced mesh 1 is three-back-shaped reinforced mesh structural member; The housing length of side of main covering reinforced mesh 1 is between 1400mm to 3000mm, and the inside casing length of side of main covering reinforced mesh 1 is 1000mm; It is square steel mesh reinforcement chip architecture part that operation hole covers reinforced mesh 2, and operation hole covers the length of side of reinforced mesh 2 between 1100mm to 1200mm; Main covering reinforced mesh 1 is welded with the reinforcing bar of operation hole covering reinforced mesh 2 by diameter 16mm, and the spacing between reinforcing bar is 150mm; Cast connector 3 is greater than the steel sleeve that 30mm, length are 100mm for internal diameter; A limit that operation hole is covered to reinforced mesh 2 by cast connector 3 is movably connected on a close reinforcing bar for main covering reinforced mesh 1 inside casing in main covering reinforced mesh 1, in the endoporus of cast connector 3, is installed with operation hole simultaneously and covers a limit of reinforced mesh 2 and a reinforcing bar in main covering reinforced mesh 1; In addition,, when operation hole covering reinforced mesh 2 covers on main covering reinforced mesh 1, operation hole covers reinforced mesh 2 and the inside casing of main covering reinforced mesh 1 should be hidden completely.
useful technique effect
This product directly covers the top, aperture that overlays on hand excavated pile, without moving around, in the time of need to descending well operations, only need open the operation hole being connected with main covering reinforced mesh 1 and cover reinforced mesh 2, can enter construction site, effectively reduce operation perforated area, reduce potential safety hazard, convenient, fast---during operation, open hole and cover, after operation, close, simplify construction and cover, increase job safety coefficient.
In addition,, in the process of operation, builder can, from operation hole being covered reinforced mesh 2 and main covering reinforced mesh 1 closure, reduce the danger of foreign material accidental falling hand excavated pile working region, building site.
In addition, the opening of the main covering reinforced mesh 1 of this product is little, and the covering of the operation hole on it reinforced mesh 2 volumes are little, lightweight, are convenient to open, closure, are conducive to production safety management.
Finally, this production is simple, easy to use, can guarantee the personnel of non-activity duration and the safety of hole quality, and in the time of preventing operation again, the large thing of periphery falls and personal security, and arranges simple, attractive in appearancely, practical, and repeatedly utilization rate is high.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is the front view of Fig. 1.
Sequence number in figure is: main covering reinforced mesh 1, operation hole cover reinforced mesh 2, cast connector 3.
The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
Referring to Fig. 1, combined type aperture covering, comprises that main covering reinforced mesh 1, operation hole cover reinforced mesh 2 and cast connector 3; Wherein, main covering reinforced mesh 1 is three-back-shaped reinforced mesh structural member; The housing length of side of main covering reinforced mesh 1 is between 1400mm to 3000mm, and the inside casing length of side of main covering reinforced mesh 1 is 1000mm; It is square steel mesh reinforcement chip architecture part that operation hole covers reinforced mesh 2, and operation hole covers the length of side of reinforced mesh 2 between 1100mm to 1200mm; Main covering reinforced mesh 1 is welded with the reinforcing bar of operation hole covering reinforced mesh 2 by diameter 16mm, and the spacing between reinforcing bar is 150mm; Cast connector 3 is greater than the steel sleeve that 30mm, length are 100mm for internal diameter; A limit that operation hole is covered to reinforced mesh 2 by cast connector 3 is movably connected on a close reinforcing bar for main covering reinforced mesh 1 inside casing in main covering reinforced mesh 1, in the endoporus of cast connector 3, is installed with operation hole simultaneously and covers a limit of reinforced mesh 2 and a reinforcing bar in main covering reinforced mesh 1; In addition,, when operation hole covering reinforced mesh 2 covers on main covering reinforced mesh 1, operation hole covers reinforced mesh 2 and the inside casing of main covering reinforced mesh 1 should be hidden completely.
Referring to Fig. 2, cast connector 3 is mainly used in main covering reinforced mesh 1 and covers being connected of reinforced mesh 2 with operation hole, and every cover combined type aperture covering is used 2 cast connectors 3.Cast connector 3 covers reinforced mesh 2 with main covering reinforced mesh 1, operation hole and adopts two-way welding, forms rotatable flexible connection.
