Description
Technical field
The invention belongs to the realm of building construction, particularly to a kind of concrete embedded part having enough to meet the need use.
Background technology
Jumbo, the facilities such as tower crane that at present construction is used, elevator, moulding bed, mould bases it is frequently necessary to be connected with structure by concrete embedded part, along with building height, span, the increase of the scale of construction, jumbo, the embedded part scale of construction of facility the most constantly increase, quantity is on the increase, tradition embedded part cannot have enough to meet the need use, and mega project embedded part puts into the most millions of the most.It addition, the making of substantial amounts of large-scale embedded parts, process, the amount of labour that detects and cost also can not be ignored, and the mass defect processed often becomes the major hidden danger that embedded part uses.
Summary of the invention
In order to solve the problem that tradition embedded part cost is high, labour force puts into greatly, security risk is high, the present invention provides a kind of dimpling can have enough to meet the need concrete embedded part, and this built-in fitting is prefabrication approved product, can have enough to meet the need use.
For achieving the above object, the technical solution used in the present invention is: dimpling can have enough to meet the need concrete embedded part, it is characterised in that: include anchor slab 1, backboard 5, to pull bar 2, pad 3, nut 4 and PVC sleeve pipe 6；It is equipped with multiple [such as 2-20 on anchor slab 1, backboard 5, the present embodiment uses 3 to pulling eye] to pulling eye 1.2, one end of pull bar 2 is screwed on nut 4 through what PVC sleeve pipe 6 was then passed through on backboard 5 again to pulling eye rear enclosure Upper gasket 3, to the other end of pull bar 2 through on anchor slab 1, pulling eye rear enclosure Upper gasket 3 being screwed on nut 4 again, corresponding with the number to pulling eye on anchor slab 1 to the number of pull bar；The lateral surface of anchor slab 1 is fixed with joint outer part 1.4, and the medial surface (one side of casting concrete) of anchor slab 1 is provided with multiple [such as 2-20, the present embodiment uses 4 grooves] groove 1.1, and the periphery of groove 1.1 is provided with chamfering 1.3.
The turnover that present invention achieves the realm of building construction concrete embedded part uses, substitute jumbo, traditional embedded parts of facility such as tower crane, elevator, moulding bed, mould bases, and then save embedded part and put into, especially Super High, large span, the medium and heavy equipment of large building, that the large-scale embedded parts of facility often can save millions of unit is the most.It addition, this embedded part is as the approved product of factory process, quality is good, precision is high, safety is the most secure, it is to avoid temporary component processing is because the major safety risks that cause of problems of welded quality；Finally, according to the difference of built-in fitting bearing capacity, this embedded part can be designed to the series of products of different size, thus meets distinct device, the needs of facility built-in fitting construction.
The invention has the beneficial effects as follows, this built-in fitting is prefabrication approved product, and quality is good, precision is high, can design the many specification products meeting different bearer power demand, and turnover uses, economic benefits.

Detailed description of the invention
Implement see Fig. 1, Fig. 2, dimpling can have enough to meet the need concrete embedded part, including anchor slab 1, backboard 5, to pull bar 2, pad 3, nut 4 and PVC sleeve pipe 6；It is equipped with multiple [such as 2-20 on anchor slab 1, backboard 5, the present embodiment uses 3 to pulling eye] to pulling eye 1.2, one end of pull bar 2 is screwed on nut 4 through what PVC sleeve pipe 6 was then passed through on backboard 5 again to pulling eye rear enclosure Upper gasket 3, to the other end of pull bar 2 through on anchor slab 1, pulling eye rear enclosure Upper gasket 3 being screwed on nut 4 again, corresponding with the number to pulling eye on anchor slab 1 to the number of pull bar；The lateral surface of anchor slab 1 is fixed with joint outer part 1.4, and the medial surface (one side of casting concrete) of anchor slab 1 is provided with multiple [such as 2-20, the present embodiment uses 4 grooves] groove 1.1, and the periphery of groove 1.1 is provided with chamfering 1.3.
Described anchor slab 1 comprises groove 1.1, to pulling eye 1.2, chamfering 1.3；Described pull bar 2 is tightened by pad 3 and nut 4 after be fixed on anchor slab 1 and backboard 5 surface；
Described concrete seven surface has concrete projection 7.1 at anchor slab groove 1.1.
External device (ED) transmits axle power, shearing and moment of flexure by joint outer part 1.4 to described built-in fitting, built-in fitting top is to pull bar 2 tension, bottom anchor slab 1 and the concrete seven extruding outside axle power of pressurized opposing and Moment, anchor slab groove 1.1 7.1 effect opposing outside shearing actions protruding with concrete.
Described to pull bar 2 after nut 4 screws out with pad 3, can take out in PVC sleeve pipe 6；Described anchor slab 1 and backboard 5, after taking out pull bar 2, can take off from concrete seven surface, thus realize turnover.
Anchor slab 1 surface has multiple groove 1.1 and to pulling eye 1.2；Described groove 1.1 position forms the protruding 7.1 outside shearing actions of opposing of concrete in concreting process；Described to pulling eye 1.2 by anchor slab and backboard are fixed on concrete surface by pull bar 2.
Groove 1.1 can be to use different form, and such as the shape such as the most trapezoidal square, circular, groove 1.1 surrounding must have chamfering 1.3 so that anchor slab 1 takes off from concrete surface.
All there is pull bar 2 two ends screw thread to be positioned at anchor slab 1 outside with backboard 5, fixed by nut 4 and pad 3；Described to pull bar 2 by anchor slab by pulling force time act on, pulling force is transferred on the nut 4 of backboard 2 side by pull bar 2, then by this nut 4 by load being transferred to concrete with the extruding of backboard 5.
The present invention to be embodied as step as follows:
Step one, before concrete seven pours, by anchor slab 1, backboard 5, installs in place to pull bar 2, pad 3, nut 4 and PVC sleeve pipe 6, and is fixed.
Step 2, casting concrete 7, concrete projection 7.1 is formed in anchor slab 1 groove 1.1 position；
Step 3, the joint outer part 1.4 bearing load effect on anchor slab 1, form axle power, shearing and moment of flexure that built-in fitting bears；To pull bar 2 tension, anchor slab 1 extrudes pressurized with concrete seven, and concrete projection is cut opposing external load effect；
Step 4, after joint outer part position load is removed, first screws out nut 4 and pad 3, hereafter will take out pull bar from PVC sleeve pipe 6, and preparation turnover next time of finally anchor slab and backboard being backed off uses.
