The specific embodiment

Below in conjunction with the description of drawings and the specific embodiment the utility model is further described:

A kind of novel bridge cut-off insulation connector that carries insurance shown in Fig. 1 to 8, it is characterized in that: comprise a U type anchoring piece 10 that anchors into wall 4 and anchor into wall 4 outside outer 5 the 2nd U type anchoring pieces 20 that cover, a described U type anchoring piece 10 is with the 2nd U type anchoring piece 20 mutual make-ups but do not contact, and maintain certain distance, heat just can't directly be passed to another U type anchoring piece from a U type anchoring piece like this, be provided with the wrap member 2 of low thermal conductivity outside the position of a U type anchoring piece 10 and the 2nd U type anchoring piece 20 mutual make-ups, described wrap member 2 is arranged on described wall 4 and covers in the insulation layer 6 between outer 5.In order to improve its whole tension, resistance to compression, shear strength, this wrap member 2 is made by the Materials with High Strength of low thermal conductivity.Because two U type anchoring pieces are directly contact not,, make whole connector have certain tension, resistance to compression, shear resistance wrap member 2 and just play this effect so will wrap up the strong Materials with High Strength of a kind of anti-pressure ability in its position that interlocks.

As shown in Figure 3, can be provided with heat insulation 3 in the position of a described U type anchoring piece 10 and the 2nd U type anchoring piece 20 mutual make-ups in the utility model.With tensile strength and its safety factor in fire of raising of strengthening itself, this heat insulation 3 has low thermal conductivity, high anti-pressure ability, and the characteristic of not firing is arranged.Described heat insulation 3 can be pottery or foamed ceramics etc.

In order to improve the anchoring strength of U type anchoring piece in concrete, its end shape can be that straight shape is with ribbing, also can be following several modes:

First kind, as shown in Figure 4, a described U type anchoring piece 10 becomes bending with wall 4 junctions; Described the 2nd U type anchoring piece 20 becomes bending with outer 5 junctions of covering.

Second kind, a described as shown in Figure 5 U type anchoring piece 10 and wall 4 junction wavinesses; Described the 2nd U type anchoring piece 20 and the outer 5 junction wavinesses of covering.

The third, the end of a described as shown in Figure 6 U type anchoring piece 10 becomes swallow-tail form; The end of described the 2nd U type anchoring piece 20 becomes swallow-tail form.

The anchoring piece of U type anchoring piece 1 described in the utility model for making by the high temperature resistant nonflammable material of high strength such as reinforcing bar or pottery.U type anchoring piece wherein suitably can also be extended, form a kind of bridge cut-off reinforcing bar, be applied to local heat-insulating bridge-cut-off such as balcony, air-conditioning plate and connect.
