Specific embodiment

It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.

Embodiment one:

As shown in Figure 1, the structural schematic diagram of the self-bearing type support frame in disclosed built-in tunnel described in the utility model, from Fig. 1 can be seen that the self-bearing type support frame in built-in tunnel, and the sliding slot 2 including being connected to tunnel wall further includes around sliding slot 2 Inner support steel loop 4, inner support steel loop 4 is set to semi-ring under tunnel 1；It is connected to the self-bearing type component 5 of sliding slot 2；Accept weight Bracket 3, bracket 3 is connected to self-bearing type component 5.Wherein, the self-bearing type support device is built in tunnel 1, herein Tunnel 1 is not the tunnel of vehicle pass-through in subway circulation, has only been designed as placing the weights such as equipment and the electric wire along subway The tunnel 1 that object is separately provided.The weights such as equipment and electric wire are placed in bracket 3, and the length of bracket 3 can be according to the volume of weight It being configured, the pressure of weight acts in bracket 3 and self-bearing type component 5 in the self-bearing type support frame in the built-in tunnel, It completely avoids equipment along the line and electric wire carrying out the damage caused by hung in tunnel 1 to 1 main structure of tunnel.

Preferably, 5 one end of self-bearing type component is buried in sliding slot 2, and structure is embedded sleeve barrel component or 506 groups of built-in sliding chute Part.As can be seen from Figure 2 using the design of embedded sleeve barrel component in the present embodiment, wherein self-bearing type component 5 includes useful In the self-bearing type bracket of connecting bracket 3.Further, the embedded sleeve barrel component includes the pre- sleeve nut for being embedded in sliding slot 2 501, the bolt 502 of fixed self-bearing type bracket, bolt 502 is connected with sleeve nut 501.The embedded sleeve barrel component is in this reality The predominantly fixed self-bearing type bracket of effect played in example is applied, and is connected using self-bearing type bracket with bracket 3, therefore, by pre- Being not directly placed on bolt 502 of weight can be made by burying sleeve assembly, and equipment and electricity in traditional design in tunnel 1 The weights such as line directly act on bolt, therefore, be easy to cause the generation of bolt looseness.

Preferably, bracket 3 is distributed in 2 surrounding of sliding slot by being connected to self-bearing type component 5, and distance is adjustable between bracket 3.Its In, when designing self-bearing type support device, it is contemplated that it is different that weight pressure may be received on different brackets 3, it is preferable that It is top half in tunnel 1, i.e., 1 upper half ring of tunnel is that bracket 3 is directly connected with self-bearing type bracket, and semi-ring exists under tunnel 1 Inner support steel loop 4 is additionally added between bracket 3 and self-bearing type bracket, the effect designed in this way is so that the big weight of quality is put It is placed in lower semi-ring, light-weight is placed in upper half ring, is placed in different brackets 3 for different weights.

Preferably, self-bearing type bracket is inverted T-shaped structural steel 503 in the design of the embedded sleeve barrel component, and is reserved with spiral shell Hole, each hole are directed to each bolt 502, and two bolts 502 are passed through screw hole and fixed knob to sleeve nut 501, into One step, it is provided with gasket 504 between the self-bearing type bracket and any bolt, also improves self-bearing type bracket and bolt 502 fixed tightness degrees.

Embodiment two:

Fig. 3 is the structural schematic diagram of 506 component of built-in sliding chute provided by the embodiment of the utility model, wherein entire self-supporting Identical in formula support device and embodiment one, different is in the embodiment for 506 component of built-in sliding chute, the i.e. embodiment only Only self-bearing type component 5 and embodiment one there are some differences, it is preferable that 506 component of built-in sliding chute includes buried in sliding slot 2 Anchor bolt 505, be connected to anchor bolt 505 and be embedded in the sliding slot 506 of sliding slot 2 in advance, the bolt 507 and nut of fixed self-bearing type bracket. Wherein, self-bearing type bracket is U-shaped structure steel 509, and is reserved with screw hole, in fixed self-bearing type bracket, U-shaped structure steel first 509 are penetrated in bolt 507 by screw hole, then U-shaped structure steel 509 are fixed up using 508 knob of nut, wherein U-shaped The gasket 504 for reinforcing fixing compact degree is also equipped between structural steel 509 and nut 508.U-shaped structure steel 509 again with bracket 3 It is fixed, to constitute self-bearing type support device.

The other structures of the self-bearing type support frame in built-in tunnel described in the present embodiment are no longer superfluous herein referring to the prior art It states.

The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model Limitation, therefore it is all without departing from the content of the technical scheme of the utility model, implement according to the technical essence of the utility model to above Any modification, equivalent variations and modification, are still within the scope of the technical solutions of the present invention made by example.
