Abstract
The utility model discloses a pre-cast nut for a fabricated structure and belongs to the technical field of engineering buildings. The pre-cast nut comprises a long-rod bolt, a long-rod nut matched with the long-rod bolt and at least two reinforcing steel bars with hooks, wherein the reinforcing steel bars with the hooks are evenly fixed on the circumference of the long-rod nut. The pre-cast nut can be effectively anchored in a prefabricated part girder plate to provide enough large drawing force, can increase reinforcing steel bar anchored length, lengthens the welded length of reinforcing steel bars and nuts, and has good tensile resistance and pulling resistance. Meanwhile, a rubber gasket is added to prevent cement paste from permeating. In addition, due to the fact that manufacturing materials can be obtained easily, the pre-cast nut is low in construction cost, convenient to process and good in economical benefits and popularization prospect.
Description
Technical field
The invention belongs to field of engineering building, particularly relate to a kind of embedded nut that is used for fabricated construction.
Background technology
In the prior art, do not have the sale of finished goods of assembling embedded nut on the building materials market, the customization of big multidirectional factory, die cost is very high, and needs special-purpose machining, adds that round freight charges have increased the cost of engineering, and can not satisfy instructions for use.Existing two kinds of structures: a kind of structure is cut into pieces bar reinforcement earlier as shown in Figure 4, and an end is processed into screw hole with thread generator, and the other end cuts away half, and is divided into Y-shaped.Another kind of structure is the afterbody welding one laterally straight reinforcing bar with long nut as shown in Figure 5.
The defective that said structure exists is: the difficulty of processing of embedded nut one as shown in Figure 4 is bigger, needs special-purpose big machinery, and processing charges is higher, and laterally anchorage length is shorter, can not well satisfy the resistance to plucking requirement.The horizontal anchor bar of embedded nut two as shown in Figure 5 only welds and a bit with embedded nut, can not well satisfy the requirement of tension pulling test strength, has potential safety hazard.
Summary of the invention
At the technical problem of above-mentioned existence, the object of the present invention is to provide a kind of embedded nut that is used for fabricated construction, material is cheap and easy to get, processes simple and easyly, and can provide enough tension resistance to plucking abilities.
In order to achieve the above object, solution of the present invention is:
The reinforcing bar of stock nut that the present invention includes bolt of long stem, cooperates with bolt of long stem and band crotch, the reinforcing bar of described band crotch evenly is fixed on the excircle of stock nut.
Also be provided with rubber sheet gasket between described bolt of long stem and stock nut.The afterbody of described stock nut has shutoff.The reinforcing bar of described band crotch is the reinforcing bar of two limbs or three limb girdle screw threads.Described reinforcing bar crotch anchorage length is 40mm～60mm.The reinforcing bar of described band crotch and the two-sided welding of stock nut, its weld length is 40mm～50mm.
Beneficial effect of the present invention:
The present invention has compared with prior art increased the anchorage length of steel bar of embedded nut, and the weld length of extended reinforcing bar and nut makes embedded nut that better tension extraction-resistant behavior be arranged.The present invention can effectively be anchored in the prefabricated units beam column plate, and enough big pulling capacity is provided, and cooperates the use of support bar, can provide interim reliably to the installation of prefabricated units and support.Increase rubber sheet gasket simultaneously, prevented the infiltration of cement paste.Because manufacturing materials is easy to get, and cost is low, process easyly in addition, better economic benefit and promotion prospect are arranged.

Among the figure: 1. bolt of long stem, 2. rubber sheet gasket, 3. stock nut, the 4. reinforcing bar of band crotch, 5. soffit formwork, 6. side template, 7. welding, 8. straight reinforcing bar, 9. vertical member, 10. inclined support bar, 11. bearing anchor slabs, 12. floors.
The specific embodiment
Specifically describe the present invention below in conjunction with drawings and Examples.
Embodiment 1: as shown in Figure 1 and Figure 2, the present invention includes the reinforcing bar 4 of bolt of long stem 1, the stock nut 3 that cooperates with bolt of long stem 1 and two band crotches, the reinforcing bar 4 of described pair of limb girdle crotch is welded on stock nut 3 excircles, can effectively be anchored in the prefabricated units beam column plate, enough big pulling capacity is provided.
The present invention is when installing and using, and 3 on described bolt of long stem 1 and stock nut also are provided with rubber sheet gasket 2.It is more firm that described rubber sheet gasket 2 can make stock nut 3 be fixed on the template, and when preventing concreting cement paste from 3 mouthfuls of infiltrations of stock nut.
The afterbody of described stock nut 3 carries out shutoff, and cement paste infiltrates from stock nut 3 afterbodys when preventing the prefabricated units concreting.
Be threaded on reinforcing bar 4 peripheries of described band crotch, adopt two limbs or three limb girdle rib steel muscle, can with concreting after form good snap-in force; Described pair of limb girdle rib steel muscle 4 and the 3 two-sided welding of stock nut, its weld length is 40mm～50mm, and this example is selected 40mm, and reinforcing bar 4 crotch anchorage lengths are 40mm～60mm, and this example selection 40mm is for embedded nut provides enough big tension pulling test strength.
As shown in Figure 3, the present invention for soffit formwork 5 or side template 6, in correspondence position boring, places the template inboard with pre-buried stock nut 3 and rubber sheet gasket 2 when using installation, bolt of long stem 1 is screwed into and tightens from the outside, need not to assist can keep supporting oneself firmly.If place the surface of member, can behind concreting, in time insert, only the nut with bolt of long stem 1 exposes, or before building with being fixed on the reinforcing cage.
Embodiment 2: this example as different from Example 1: it is used as shown in Figure 6, behind vertical member 9 hoisted in position, the bearing anchor slab 11 usefulness bolt of long stems 1 that inclined support bar 10 two ends are with holes are fixed on the embedded nut in vertical member 9 and the floor 12, thereby provide interim support to vertical member 9.Can utilize simultaneously the length adjustment function of inclined support bar 10 self that vertical member 9 is carried out push-and-pull, thereby adjust the verticality of vertical member 9.Adopt three limb girdle rib steel muscle 4 and the 3 two-sided welding of stock nut in this example, its weld length is 40mm～50mm, and this example is selected 50mm, and reinforcing bar 4 crotch anchorage lengths are 40mm～60mm, this example is selected 60mm, for embedded nut provides enough big tension pulling test strength.
Embodiment 3: as different from Example 1: adopt three limb girdle rib steel muscle 4 and the 3 two-sided welding of stock nut in this example, its weld length is 40mm～50mm, this example is selected 45mm, and reinforcing bar 4 crotch anchorage lengths are 40mm～60mm, this example is selected 50mm, for embedded nut provides enough big tension pulling test strength.
