Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering construction technology, and in particular to a simple-to-install temporary support frame for tunnel escape passages. Background Technology
[0002] Tunnel escape passages are important safety facilities within tunnels. In the event of emergencies such as tunnel collapses or fires, they provide evacuation routes to ensure the safety of personnel. They are typically made of impact-resistant and pressure-resistant materials, have sturdy connections, and are clearly marked so that personnel can quickly find and use them in an emergency.
[0003] The environment inside tunnels is complex, with potential uneven ground and loose rocks. Therefore, support frames are needed to provide stable support for escape routes. However, traditional tunnel escape route support frame installation methods are too cumbersome, and the support frames have weak anti-tilting capacity and stability. The cumbersome installation process requires more manpower and takes a long time, affecting the construction progress, extending the overall project duration, and increasing labor and management costs. At the same time, various external forces may act inside the tunnel, such as blasting vibrations, rockfall impacts, and ground movement. Support frames with poor anti-tilting capacity are prone to tilting and displacement under these external forces, causing deformation of the escape route, affecting its normal use, and even blocking the route, hindering personnel escape.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0030] Example 1:
[0031] Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a simple installation temporary support frame for tunnel escape passages, including a support plate 1. A vertical plate 2 and a horizontal plate 3 are fixedly connected to the inner wall of the support plate 1, and the bottom of the vertical plate 2 is fixedly connected to the top of the horizontal plate 3. A connecting plate 4 is fixedly connected to the inner wall of the support plate 1. An installation component 5 is provided on one side of the support plate 1, and a support component 7 is provided on the outer side of the installation component 5.
[0032] Support plate 1 serves as the core support surface of the entire device, directly contacting the inner wall of the tunnel arch, distributing the weight of the passage, and preventing collapse caused by uneven local stress. Vertical plate 2 and horizontal plate 3 form an inverted T-shaped reinforcing structure inside support plate 1, significantly improving the bending and shear resistance of support plate 1, ensuring stability under heavy loads. Connecting plate 4 is used to connect support plate 1, and rigid connection is achieved through the third fixing bolt 15, enhancing the overall integrity of the structure.
[0033] The mounting assembly 5 includes a support rod 51 disposed on one side of the support plate 1, and the number of support rods 51 is set to four sets. A fixing frame 52 is disposed on the outer side of the support rod 51, and a first fixing bolt 53 for fixing the fixing frame 52 is threadedly connected to the inner wall of the support rod 51, and the outer side of the first fixing bolt 53 is threadedly connected to the inner wall of the fixing frame 52.
[0034] Four vertically arranged support rods 51 form the main frame, providing vertical load-bearing capacity and serving as the installation base for other components. The fixed frame 52, together with the first fixing bolt 53 and the third fixing bolt 15, facilitates the installation and disassembly of the connecting plate 4, making the process relatively convenient. The first fixing bolt 53 passes through the fixed frame 52 and the support rods 51 laterally to prevent the fixed frame 52 from sliding laterally and ensure connection stability.
[0035] The support assembly 7 includes a first mounting frame 71 installed on the outside of the support rod 51. A ramp 72 is fixedly connected to one side of the first mounting frame 71 by bolts, and a second mounting frame 73 is fixedly connected to one end of the ramp 72.
[0036] The first mounting frame 71 and the second mounting frame 73 are respectively fixed to the outside of the support rod 51 and the inclined plate 72. They are connected by bolts to achieve quick assembly. At the same time, the inclined plate 72 is set at a 45° angle to form a triangular support structure, which converts the vertical load into oblique tensile and compressive forces, greatly improving the overall structure's anti-tilting ability and stability.
[0037] Example 2:
[0038] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0039] Specifically, the inner wall of the fixed frame 52 is provided with a transverse groove 6 for installing the connecting plate 4.
[0040] The design of the transverse slot 6 is to provide space for the installation of the connecting plate 4.
[0041] Specifically, a base 8 is installed on the outside of the support rod 51, and the number of bases 8 is set to four.
[0042] The base 8 increases the contact area with the ground, reduces the pressure on the tunnel floor, and prevents the support frame from sinking or sliding.
[0043] Specifically, the inner wall of the support rod 51 is threaded with a second fixing bolt 9 for fixing the base 8, and the outer side of the second fixing bolt 9 is threaded with the inner wall of the base 8.
[0044] The second fixing bolt 9 secures the base 8 to the support rod 51, ensuring that the base 8 does not shift when subjected to force, and also facilitates the disassembly of the base 8.
[0045] Specifically, a mounting bracket 10 is fixedly connected to one side of the base 8, and the number of mounting brackets 10 is set to two sets, with the two sets of mounting brackets 10 designed symmetrically at the center line of the support plate 1.
[0046] The mounting bracket 10 is symmetrically arranged on both sides, providing additional lateral support points and improving the stability of the device.
[0047] Specifically, the inner wall of the mounting frame 10 is fixedly connected with two sets of uprights 11, and the two sets of uprights 11 are symmetrically designed with respect to the center line of the mounting frame 10.
[0048] The installation of uprights 11 enhances the vertical stiffness of the mounting bracket 10 and further constrains structural deformation.
[0049] Example 3:
[0050] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0051] Specifically, a positioning plate 12 is fixedly connected to one side of the upright 11 by bolts, and the number of positioning plates 12 is set to two.
[0052] The positioning plate 12 is provided to enhance the stability of the mounting bracket 10, and the positioning plate 12 is connected by bolts to further constrain structural deformation.
[0053] Specifically, the inner wall of the mounting bracket 10 is fixedly connected with an arc-shaped bracket 13 and a positioning rod 14, and the outer side of the arc-shaped bracket 13 is fixedly connected to one side of the positioning plate 12.
[0054] The arc-shaped frame 13 and the positioning rod 14 are designed to provide lateral support, while the positioning rod 14 strengthens the connection rigidity between the arc-shaped frame 13 and the mounting frame 10.
[0055] Specifically, a mounting pad 16 for mounting the third fixing bolt 15 is installed on the top of the fixing frame 52, and the inner wall of the mounting pad 16 is threadedly connected to the outer side of the third fixing bolt 15.
[0056] The third fixing bolt 15 secures the connecting plate 4 to the fixing frame 52, and the mounting pad 16 increases the contact area, disperses the pressure of the third fixing bolt 15, and prevents loosening.
[0057] In use, the support plate 1 is placed in a predetermined position inside the tunnel, making it contact the tunnel's arched inner wall to bear the vertical pressure from the escape passage. The inverted T-shaped structure formed by the vertical plate 2 and the horizontal plate 3 enhances its strength and resists deformation under heavy load. Four sets of support rods 51 are then installed on the base 8 to form the main frame, bearing the vertical gravity. The first fixing bolt 53 is then used to horizontally penetrate the fixing frame 52 and the support rods 51 to fix the fixing frame 52, preventing it from sliding laterally. Simultaneously, the third fixing bolt 15 further tightens the connecting plate 4 to the fixing frame 52, enhancing the overall connection stability. This completes the assembly of the installation component 5, thus fixing the support plate 1 fixed to the top of the connecting plate 4. The first mounting frame 71 is then installed on the outside of the support rods 51. The inclined plate 72 is then connected to the first mounting frame 71 using bolts. The other end of the inclined plate 72 is connected to the second mounting frame 73. The inclined plate 72 is set at a 45° angle, forming a triangle with the support rods 51, etc. The support structure, when subjected to vertical loads from the escape tunnel, transforms the vertical force into oblique tensile and compressive forces. Utilizing the stability principle of triangles, this significantly enhances the overall structure's resistance to lateral tilting, providing reliable support for the escape tunnel. Simultaneously, four sets of bases 8 increase the contact area with the ground, preventing the entire device from sinking into the ground or sliding. The mounting bracket 10 connected to one side of the base 8 provides additional lateral support points. The uprights 11 on the mounting bracket 10 enhance vertical stiffness. The positioning plate 12, connected by bolts, further constrains structural deformation. The arc-shaped frame 13 and positioning rod 14 conform to the tunnel wall, providing lateral support. The positioning rod 14 reinforces the connection between the arc-shaped frame 13 and the mounting bracket 10, ensuring the stable support of the entire temporary support frame in complex tunnel environments, thereby improving the overall stability of the device. When disassembly is required, the third fixing bolt 15, the first fixing bolt 53, and the second fixing bolt 9 are disassembled sequentially to remove the support plate 1, making disassembly convenient and quick.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
