The specific embodiment
As shown in Figure 1, the top insulation system of the subway shield door that the utility model provides, top body of wall 1 has overhang under one side direction of shielded gate top, shielded gate 2 tops are fixed on described top body of wall 1 by the attaching parts 21 of corner shape, described attaching parts 21 is fixed together with described top body of wall 1 by penetrating bolt 3 again, and these are prior art.And the utility model also has following unique design:
First the utility model provides cross-sectional plane to be Z-shaped insulcrete 4(as shown in Figure 2), and downside surface, top body of wall 1 that three planes of described insulcrete 4 are covered on respectively to top body of wall 1 are towards the surface of attaching parts 21 1 sides and the uper side surface of attaching parts 21.The desirable 1-3 rice of the single length of described insulcrete 4, a plurality of described insulcretes 4, along omnidistance laying the in top of described shielded gate 2, are used insulating gel blind between adjacent insulcrete 4, and playing is substantially the most also the insulating effect of most critical.Described insulcrete 4 not only forms a part for shielded gate 2 insulation systems, can also play the function of top body of wall 1 insulation.
For reinforced insulation effect, between described insulcrete 4 and the downside surface of top body of wall 1 and and top body of wall 1 between the surface of attaching parts 21 1 sides, all scribble Waterproof glue line 41, can stop the intrusion to insulcrete 4 of moisture in the cement concrete of top body of wall 1.
Then, between described insulcrete 4 and described attaching parts 21, be also equipped with at least one deck insulating pad 5, with the shield effectiveness between reinforced top body of wall 1 and shielded gate 2 tops, in the situation that described insulcrete 4 contingency lost efficacy, described insulating pad 5 can keep the effect that insulate.
The side pressure that need to bear shielded gate 2 due to described insulcrete 4 and insulating pad 5, require its bending strength to be greater than 170MPa, described insulcrete 4 preferably adopts makrolon material, and described insulating pad 5 preferably adopts makrolon material, epoxy vinyl ester composite material or stupalith.
The described tail end that penetrates bolt 3 passes described attaching parts 21, described insulating pad 5, described insulcrete 4 and described top body of wall 1 successively, and joins with nut 31, and described shielded gate 2 is fixed on to described top body of wall 1 one sides.For fear of described bolt 3 conductions that penetrate, also for fear of pollutants, along the described bolt 3 that penetrates, enter in shielded gate 2 places, at described head end insulating tube of bolt 3 upper sleeve through 61, tail end insulating tube 62 and the external insulation casing pipe 63 of penetrating, described head end insulating tube 61 passes successively described attaching parts 21, described insulating pad 5 and described insulcrete 4 and inserts in described top body of wall 1, and obstruct penetrates between bolt 3 head ends and described attaching parts 21 described; Described tail end insulating tube 62 stretches in described top body of wall 1 from the described tail end direction that penetrates bolt 3, and obstruct penetrates between bolt 3 tail ends and described top body of wall 1 described; Described external insulation casing pipe 63 inserts in described top body of wall 1 from described insulcrete 4, and connect airtight with the outer wall of its inwall and described head end insulating tube 61 and the outer wall of tail end insulating tube 62, make to form between top body of wall 1 and shielded gate 2 mazy hermetic barrier structure, when described head end insulating tube 61 or tail end insulating tube 62 stretch and adjust, still can avoid 1 pair of shielded gate of top body of wall 2 to produce and pollute.
In order to reach better hermetic barrier effect, between described external insulation casing pipe 63 and described head end insulating tube 61 and tail end insulating tube 62, can also apply sealant.And the exposed junction of described external insulation casing pipe 63, head end insulating tube 61 and tail end insulating tube 62 all has the shaft shoulder, rely on the bending block contaminants of the shaft shoulder.
In addition, the described bolt 3 that penetrates passes after described top body of wall 1 and described nut 31, a bolt sheath 7 is also threaded, described bolt sheath 7 connects airtight with the shaft shoulder of described tail end insulating tube 62, thereby will described in penetrate bolt 3 and described nut 31 airtight, except thering is insulating effect, can also effectively avoid the pollutants outside top body of wall 1 to enter shielded gate 2 along the described bolt 3 that penetrates.
Wherein, described head end insulating tube 61, tail end insulating tube 62, external insulation casing pipe 63 and described bolt sheath 7 preferably adopt epoxy vinyl ester composite material or stupalith.
From above-mentioned record, the utility model is coated the Z-shaped insulcrete 4 of top body of wall 1 use, attaching parts 21 completely cuts off with head end insulating tube 61, tail end insulating tube 62, external insulation casing pipe 63 and bolt sheath 7 with 3, the bolt that penetrates of top body of wall 1 junction, just no longer there is the conducting region causing because polluting, can effectively avoid failure of insulation.
Above embodiment describes the utility model; but not the summary of being restricted property; those of ordinary skills are under the guidance of inventive concept of the present utility model; can also make modification and replacement on a lot of conventional structures, these are revised with replacement and also should be considered to belong among protection domain of the present utility model.
