Abstract
The utility model relates to a heat preservation layer splicing ground anchor for field-making wall, which comprises a mainly cap, a pole, a pole core, a wing sheet, a press disc, a washer and a nylon screw. At least two wing sheets are positioned in the axial direction of the outer surface of the pole. The wing sheet is parallel to the pole and extending outward and becoming thinner gradually, with one end connecting with the cap and the other end becomes narrow gradually and contacts with the tip as a whole. The screw hole meeting the nylon screw is made in the center of the cap. The pole core is arranged inside the central shaft under the screw hole. Bard grooves and saw teeth are positioned on the outer edge of the wing sheet. The outer surface of the pole is provided with scale-shape pattern. The bard grooves can hold the steel bar and hang concrete slurry to increase relative pull force. The tip head of the splicing anchor and the outer edge of the wing sheet are designed into saw teeth shape, which assures the anchor threading through the heat preservation board easily.
Description
Technical field
The utility model relates to the plug connector that is used for the cast-in-situ wall external thermal insulation in a kind of construction work, particularly a kind of cast-in-place wall external thermal insulation grafting holdfast.
Background technology
The external thermal insulation of body of wall uses the grafting bolt usually in the construction work in the prior art, several grafting bolts are fixed between external thermal insulation and the body of wall reinforcing bar, casting cement makes insulation layer and body of wall by firm linking together then, grafting bolt of the prior art generally includes plate, chassis and metal bolts securing member etc., as disclosed technology in the German patent DE 29909236, this grafting bolt complex manufacturing, cost height, bearing capacity is subjected to certain limitation.
Summary of the invention
The purpose of this utility model provide a kind of easy construction flexibly, connect reliable cast-in-place wall external thermal insulation grafting holdfast, it has stronger bearing capacity and pulling force, can satisfy various surfaces and paste the connection request of wall or other exterior wall finish, and have good surperficial crack resistance.
The purpose of this utility model realizes as follows: it mainly comprises the head of a nail, nail bar, nail rod core, fin, platen, pad and nylon bolt, the nail rod outer surface of described grafting holdfast axially on have two fins at least, the parallel nail bar of fin stretches out and attenuation gradually, the one end is connected with the head of a nail, the other end narrows down gradually and the nail point is integrated, center at the head of a nail has the hole, and along the nail bar central axis extend to form the screw that is screwed with nylon bolt downwards, be provided with nail rod core in the central axis of the following boat nail bar of screw.The outer rim of fin has a plurality of barb grooves, is provided with a plurality of sawtooth on the fin outer rim between the head of a nail and the adjacent barb groove, and the external surface of nail bar is provided with fish scale shape ripple.
Good effect of the present utility model is as follows: because the grafting holdfast is provided with down groove, it not only can block reinforcing bar, simultaneously can tangle the concrete mortar layer by layer and increase relative pulling force, and the design of the zigzag of sharp tip-angled shape head of grafting holdfast and fin outer, the holdfast that can guarantee to peg graft passes warming plate smoothly, and the effect of nail rod core is the anti-shearing force of gaining in strength.

The specific embodiment
Below in conjunction with drawings and Examples cast-in-place wall being incubated the grafting crab-bolt outward is described in further detail:
As shown in Figure 1, described cast-in-place wall external thermal insulation grafting holdfast, mainly comprise the head of a nail 1, nail bar 2, nail rod core 11, fin 3, platen 4, pad 5 and nylon bolt 6, nail bar 2 external surfaces of described grafting holdfast axially on have two fins 3 at least, fin 2 parallel nail bars 2 stretch out and attenuation gradually, the one end is connected with the head of a nail 2, the other end narrows down gradually and the nail point is integrated, center at the head of a nail 2 has the hole, and along the nail bar 2 central axis extend to form the screw 9 that is screwed with nylon bolt 6 downwards, be provided with nail rod core 11 in the central axis of the following boat nail bar of screw 9.The outer rim of fin 3 has a plurality of barb grooves 8, is provided with a plurality of sawtooth 7 on fin 3 outer rims between the head of a nail 1 and the adjacent barb groove 6, and the external surface of nail bar 2 is provided with fish scale shape ripple 10.
Present embodiment adopts on nail bar 2 three fins 3, and three barb grooves 8 are arranged on each fin 3, and nail rod core 11 is the design scheme of metal material.
The main body of present embodiment is the plastics holdfast of injection mo(u)lding, so cost is cheap relatively.Be incubated the warming plate that the grafting holdfast passes the polyphenyl material outside can be in cast-in-situ wall construction with some described cast-in-place walls, and reinforcing bar is stuck in the barb groove, can realize fixing and assembling to warming plate, the part that the nail bar of grafting holdfast passes warming plate during concreting is embedded among the concrete wall, the head of a nail is stuck in warming plate makes it be close to body of wall outward, again bolt, pad, pressing plate, expanded metal lath are located successively, screw bolt, smeared the facing mortar layer and promptly finished whole construction.The groove that falls on the grafting holdfast not only can block reinforcing bar in the construction as can be seen, and can tangle the concrete mortar layer by layer simultaneously increases relative pulling force, and the fish scale shape ripple of nail rod outer surface also can play the effect that mortar increases pulling force of blowing.And the design of the zigzag of sharp tip-angled shape head of grafting holdfast and fin outer, the holdfast that can guarantee to peg graft passes warming plate smoothly, and the metal nail rod core can effectively be gained in strength and anti-shearing force.
