Description
Technical field
The utility model relates to the realm of building construction, specially a kind of large scale prefabricated concrete component lifting anticreep construction dress
It sets.
Background technique
Large scale prefabricated concrete component lifting is general to use default hanging ring or open up when using mechanical suspender lifting mode
Lifting hole(eyelet).The operations such as the subsequent needs excision of hanging ring structure, and waste material.Lifting hole(eyelet) structure, need to be in the concrete component wall lifted in advance
Upper aperture.For anticreep, through-hole is generally used, certain measure anticreep then is taken to suspension hook in inside.But certain component water
Close property is more demanding, forbids that through-hole is arranged, causes difficulty to lifting.
Utility model content
In order to solve the above problem, it is simple to provide a kind of operation for the utility model, can not only guarantee structure watertightness, but also can expire
The device of foot lifting anticreep demand.
The utility model technical solution used for the above purpose is: large scale prefabricated concrete component lifts anticreep
Device, it is characterised in that: including one group of anticreep knot being separately positioned on the concrete component and hoisting appliance suspension hook of pre- lifting
Structure；The disconnecting prevention structure being arranged on the concrete component lifted in advance is to open up at least on the concrete component lifted in advance
Two not through holes, do not bury outer tube, inner sleeve in through hole, housing pipe diameter is less than inner sleeve, the difference of two sections of steel sleeves
It is worth position and constitutes " recessed " the type limit space for being used for anticreep；The disconnecting prevention structure being arranged on hoisting appliance suspension hook is gib head
Anti-skid piece is connected above front end.
Length of the aperture segment and remaining non-penetrating component that the not through hole is constituted in precast concrete section
Than for 5:3.
The precast concrete wall thickness 400mm, the aperture segment length that through hole is constituted are 250mm, and residue is not
Penetrating component length is 150mm.
Outer tube and inner sleeve length of tube ratio 3:2 in the aperture segment that the not through hole is constituted.
The length of the outer tube is 150mm, caliber 245mm, wall thickness 16mm；The length of inner sleeve is 100mm, caliber
For 273mm, wall thickness 8mm.
The outer tube and inner sleeve are steel pipe, between the two using welded connecting.
Described anti-skid piece uses section to make for trapezoidal Q345 steel plate, is welded in gib head end.
The utility model proposes large scale prefabricated concrete component lifting anti-drop device construction when, resistance will be welded with first
The suspender suspension hook of sliding block is inserted into lifting hole(eyelet), and suspension hook front end limited block is caught in the difference position of two sections of steel sleeves, limits sliding to outward turning
And go out.After suspension hook enters hole, traction rope is affected slowly to carry out lifting operation.The setting of this structure provides for the operation of suspension hook
Safety guarantee, can especially meet that watertightness is more demanding, must setting not through-hole engineer application.
Detailed description of the invention
Fig. 1 is the schematic diagram that the large scale prefabricated concrete component of the utility model lifts anti-drop device；
Fig. 2 is that the utility model suspension hook in construction enters hole schematic diagram；
In figure: 1, not through hole；2, outer tube；3, inner sleeve；4, anti-skid piece.
Specific embodiment
Embodiment
As shown in Figure 1, large scale prefabricated concrete component lifts anti-drop device, the concrete including being separately positioned on pre- lifting
One group of disconnecting prevention structure on component and hoisting appliance suspension hook；The disconnecting prevention structure being arranged on the concrete component lifted in advance
To open up at least two not through hole 1 on the concrete component lifted in advance, outer tube 2, inner sleeve not buried in through hole 1
3,2 diameter of outer tube is less than inner sleeve 3, and the difference position of two sections of steel sleeves constitutes " recessed " the type limit space for being used for anticreep；Institute
Stating the disconnecting prevention structure being arranged on hoisting appliance suspension hook is that anti-skid piece 4 is connected above gib head front end.
Length of the aperture segment and remaining non-penetrating component that the not through hole 1 is constituted in precast concrete section
Than for 5:3.
In the present embodiment, the precast concrete wall thickness 400mm, through hole 1 constitute aperture segment length be
250mm, remaining non-penetrating component length are 150mm.
Outer tube 2 and 3 length ratio 3:2 of inner sleeve in the aperture segment that the not through hole 1 is constituted.
In the present embodiment, the length of the outer tube is 150mm, caliber 245mm, wall thickness 16mm；The length of inner sleeve
For 100mm, caliber 273mm, wall thickness 8mm.
The outer tube 2 and inner sleeve 3 are steel pipe, between the two using welded connecting.
Described anti-skid piece 4 uses section to make for trapezoidal Q345 steel plate, is welded in gib head end.
As shown in Fig. 2, the method for carrying out large scale prefabricated concrete component lifting anticreep construction using device in embodiment 1,
One group of disconnecting prevention structure is respectively set on the concrete component and hoisting appliance suspension hook lifted in advance；In construction, suspension hook is inserted first
Enter not through hole 1, " recessed " the type limit space for anticreep for constituting the anti-skid piece 4 difference position for being caught in two steel sleeves
It is interior, after each suspension hook enters hole, traction rope is affected slowly to be lifted, overturn.
In actual use, hoisting appliance is hung at the top of concrete component to be lifted by crane, lifts rigging hook, opening is hung
The boom of frame is transferred at suspension hook to lifting hole(eyelet), and decentralization lockset hook clamps boom, and suspension hook enters lifting hole(eyelet), lifts hanger, completes handling
Movement, service efficiency are high, safe and reliable.
