Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to a shielded door insulation module and its construction method. Background Technology

[0002] With the acceleration of urbanization, urban rail transit (such as subways and light rail) has become one of the main modes of transportation for people. During the operation of rail transit, trains obtain high-voltage electrical energy through the third rail or overhead contact line. In order to ensure the personal safety of passengers waiting on the platform and prevent electric shock accidents caused by step voltage or accidental contact with live parts, platform screen door systems are usually installed at the edge of the platform.

[0003] To further enhance safety, the platform floor beneath the platform screen doors typically requires an insulation layer. Currently, the conventional insulation layer construction process often employs the "concealed laying method," which involves sequentially laying a leveling layer, an insulation roll (such as PVC or polymer waterproof roll), and then successively laying concrete mortar and marble on the platform's civil engineering structure.

[0004] However, the existing construction and structure of shielded door insulation modules have the following significant technical defects and safety hazards:

[0005] Safety Hazards and Construction Interference Arising from Exposed Insulation Membrane Edges: To ensure insulation continuity, traditional construction methods require leaving an edge of the insulation membrane between insulated and non-insulated areas. This edge typically protrudes above the ground (approximately 10-20cm), affecting not only the overall aesthetics of the platform but, more importantly, posing a significant tripping hazard to construction workers during subsequent station renovations, equipment installation, and commissioning. Furthermore, the edge is easily scratched or torn by on-site building materials and tools, damaging the insulation layer and creating permanent safety hazards.

[0006] The construction process is lengthy and cumbersome: traditional methods require waiting for the concrete layer to dry completely before cutting the edges and sealing the gaps. This "waiting-cutting-sealing" two-stage operation mode greatly prolongs the construction period and is not conducive to controlling the project schedule. Summary of the Invention

[0007] Therefore, it is necessary to provide a shielding door insulation module with short construction period and high construction safety performance, as well as its construction method.

[0008] To address the aforementioned technical problems, this application provides the following technical solution:

[0009] An insulation module for a platform screen door is located between the screen door and the non-insulated area of ​​the platform and is installed on the platform structural layer. The insulation module includes, from bottom to top, a platform leveling layer, a concrete bonding layer, and a finishing layer laid on the platform structural layer. The insulation module also includes:

[0010] An insulating roll is laid vertically between the insulating module and the non-insulated area of ​​the platform, with the top edge of the insulating roll lower than the finishing layer. The insulating roll extends horizontally between the platform leveling layer and the concrete bonding layer.

[0011] An insulating vent block is provided with a vent hole that runs longitudinally through the insulating vent block. The insulating vent block is embedded in the gap between the insulating module and the non-insulated area of ​​the platform and is used to position the top edge of the insulating roll and to vent.

[0012] In one embodiment, the insulation module is divided into multiple insulation units, and the insulation module also includes insulation baffles. The insulation baffles are provided between the shielding door and the insulation units, and between adjacent insulation units.

[0013] The insulating roll is also laid between two adjacent insulating units, between the shielding door and the insulating module, and is laid in conjunction with the insulating baffle.

[0014] In one embodiment, the insulating exhaust block is provided with a ventilation cavity, and the exhaust port is connected to the ventilation cavity.

[0015] In one embodiment, the ventilation cavity is arranged transversely along the insulating exhaust block, and the ventilation cavity is provided with reinforcing ribs.

[0016] In one embodiment, the insulation module further includes a support frame, which includes a base plate and a connecting plate connected to each other. The base plate and the connecting plate are arranged at an angle, and the base plate abuts against the concrete adhesive layer for support. The insulation vent block is installed on the connecting plate.

[0017] In one embodiment, the insulation module further includes an adjustment component connected to the insulation vent block and the connecting plate, the adjustment component adjusting the insulation vent block to move longitudinally to adjust the installation height of the insulation vent block.

[0018] In one embodiment, the adjustment assembly includes a locking member and a movable plate, the movable plate and / or the connecting plate having longitudinally extending strip holes, the locking member passing through the strip holes to connect and fix the movable plate and the connecting plate, and the insulating exhaust block being mounted on the movable plate.

[0019] In one embodiment, the height H of the insulating vent block is 70mm~100mm, and the width of the insulating vent block is 8mm~10mm.

[0020] This application also provides a construction method for a shielded door insulation module, wherein the shielded door insulation module is the same as the shielded door insulation module described in any of the above embodiments, and the construction method includes:

[0021] A platform leveling layer is laid on top of the platform structural layer;

[0022] An insulating vent block is provided, wherein a longitudinally extending through vent hole is pre-drilled on the insulating vent block, and the insulating vent block is embedded in the gap between the insulating module and the non-insulated area of ​​the platform and close to the side wall of the non-insulated area of ​​the platform.

[0023] An insulating roll is provided, which is laid vertically between the insulating module and the non-insulated area of ​​the platform, and the insulating roll is extended horizontally on the platform leveling layer, wherein the top edge of the insulating roll is in contact with the insulating vent block, and the top edge of the insulating roll and the insulating vent block are set at a height lower than the surface of the finishing layer.

[0024] Provide concrete mortar, and lay the concrete mortar horizontally on the insulating roll material above the platform leveling layer to form a concrete bonding layer;

[0025] A stone slab is provided and laid on the uncured concrete adhesive layer to form a finishing layer;

[0026] After the concrete bonding layer has solidified, the gap between the insulating module and the non-insulated area of ​​the platform is sealed.

[0027] In one embodiment, the top edge of the insulating roll is positioned 1 mm to 2 mm below the surface of the finishing layer.

[0028] In one embodiment, the construction method further includes:

[0029] An insulating baffle is provided and is installed between the shielding door and the insulating unit, and between adjacent insulating units;

[0030] An insulating roll is provided, which is laid vertically between the shielding door and the insulating unit, and between adjacent insulating units, and fixed to the insulating baffle. The insulating roll is also extended horizontally and laid on the platform leveling layer.

[0031] After the concrete bonding layer has solidified, the gaps between the shielding door and the insulating unit, as well as between adjacent insulating units, are sealed.

[0032] Compared with the prior art, the shielding door insulation module of this application adds an insulating vent block with vent holes. The insulating vent block is embedded in the gap between the insulation module and the non-insulated area of ​​the platform. It is used to position the top edge of the vertically laid insulation roll and to discharge moisture from the concrete layer in the non-insulated area of ​​the platform, preventing the concrete from delaminating and falling off later. In addition, by using the vent block in conjunction with the insulation roll, the traditional process of pre-reserved edge for the roll can be eliminated, eliminating the risk of tripping, simplifying the construction process, significantly shortening the construction period, and improving the safety, durability and insulation performance of the insulation module.

[0033] In the construction method of the platform screen door insulation module provided in this application, by setting the insulation exhaust block, the top edge of the insulation roll between the insulation module and the non-insulated area of ​​the platform is lower than the finishing layer, thereby eliminating the step of cutting and turning the edge, simplifying the construction steps. Moreover, since there is no edge turning of the insulation roll, subsequent construction does not need to wait for edge turning and cutting before carrying out the subsequent station decoration, equipment installation and commissioning stages, etc., significantly shortening the construction time. In summary, this construction method can achieve the laying of high-quality insulation modules in one go, and the construction period is significantly shortened. Attached Figure Description

[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0047] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0049] The insulation layer typically uses high-voltage insulating rolls combined with double-sided self-adhesive waterproof insulating rolls. The insulating rolls are installed using a concealed laying method, requiring a portion of the roll to be left uninsulated around the perimeter and in the separation zone. To ensure the insulation layer's effectiveness and prevent the concrete in non-insulated areas from later delaminating and detaching, a certain amount of time is needed for the moisture to dry. The uninsulated roll edges are only trimmed after the concrete has fully hardened. Only after trimming can the gaps be sealed with insulating sealant. This process is time-consuming, and the uninsulated roll edges can interfere with other units' work and pose safety hazards.

[0050] Therefore, such as Figure 1 and Figure 2 As shown, one embodiment of this application provides a platform screen door insulation module 100. The insulation module is located between the platform screen door 200 and the platform non-insulated area 300 and is disposed on the platform structure layer 11. The insulation module 100 includes a platform leveling layer 12, a concrete bonding layer 13, and a finishing layer 14 laid sequentially from bottom to top on the platform structure layer 11. The platform screen door insulation module 100 also includes an insulation roll 30 and an insulation vent block 40. The insulation roll 30 is laid vertically between the insulation module 100 and the platform non-insulated area 300, and the top edge of the insulation roll 30 is lower than the finishing layer 14. The insulation roll 30 extends horizontally between the platform leveling layer 12 and the concrete bonding layer 13. The insulation vent block 40 has a vent hole 41 that extends longitudinally through the insulation vent block 40. The insulation vent block 40 is embedded in the gap between the insulation module 100 and the platform non-insulated area 300 to position the top edge of the insulation roll 30 and to vent.

[0051] Compared with the prior art, this application sets up an insulating vent block 40 with vent holes 41 between the insulating module 100 and the non-insulated area 300 of the platform. When the insulating roll 30 is laid vertically between the insulating module 100 and the non-insulated area 300, the top edge of the insulating roll 30 is lower than the finishing layer 14 and positioned on the insulating vent block 40. This eliminates the need to reserve the flange of the insulating roll 30, omitting the subsequent flange cutting step. Moreover, after the flange is installed and the concrete bonding layer 13 and the finishing layer 14 are laid, the subsequent station decoration, equipment installation and commissioning steps can be carried out directly. This can significantly shorten the construction period and avoid the safety hazards caused by the flange and the problem of insulation performance being damaged due to the breakage of the insulating roll 30. Secondly, the insulating vent block 40 vents through the vent holes 41, which can discharge the moisture in the non-insulated area 300 of the platform and prevent the problem of hollowness in the later stage.

[0052] In one embodiment, such as Figure 5 and Figure 6 As shown, the insulating vent block 40 is provided with multiple vent holes 41, which are evenly distributed along the length of the insulating vent block 40. This facilitates the rapid discharge of water vapor from the non-insulated area 300 of the platform, shortening the construction period. In other embodiments, vent holes 41 can also be added for areas where water vapor discharge is difficult.

[0053] like Figure 6 As shown, the insulating exhaust block 40 is equipped with a ventilation cavity 42, and the exhaust hole 41 communicates with the ventilation cavity 42. The ventilation cavity 42 can improve air circulation, thereby promoting the discharge of water vapor from the concrete layer of the non-insulated area 300 of the platform.

[0054] Furthermore, such as Figure 5 and Figure 6 As shown, the ventilation cavity 42 is arranged transversely along the insulating exhaust block 40, and the ventilation cavity 42 is provided with reinforcing ribs 43. The reinforcing ribs 43 are used to enhance the support strength of the insulating exhaust block 40, so that the insulating exhaust block 40 can provide stable support for the installation and positioning of the insulating roll 30, and prevent the insulating roll 30 from shifting due to unstable positioning during laying.

[0055] like Figure 5As shown, in one embodiment, the insulation module 100 further includes a support frame 50, which includes a base plate 51 and a connecting plate 52 connected to each other. The base plate 51 and the connecting plate 52 are arranged at an angle, and the base plate 51 abuts against the concrete adhesive layer 13 for support. Specifically, after the base plate abuts against the concrete adhesive layer 13, it is fixed to the concrete adhesive layer by nails, which can strengthen the support and positioning. The insulating vent block 40 is installed on the connecting plate 52. The insulating vent block 40 is pre-fixed on the connecting plate 52. During on-site construction, the base plate 51 only needs to be inserted into the gap between the decorative surface layer 14 and the concrete layer in the non-insulated area 300 of the platform to achieve the installation and positioning of the support frame 50 and the insulating vent block 40. The construction is simple and requires very little time. The setting of the support frame 50 provides stable positioning and support for the installation of the insulating vent block 40 and simplifies the construction steps. In other embodiments, the insulating vent block 40 can also be installed and fixed by other structures or methods.

[0056] like Figure 5 As shown, the insulation module also includes an adjustment component 60, which is connected to the insulation vent block 40 and the connecting plate 52. The adjustment component 60 adjusts the longitudinal movement of the insulation vent block 40 to adjust its installation height. Due to variations in the height of civil works in different areas of the construction site, a perfectly level plane cannot be achieved. The adjustment component 60 allows for fine-tuning of the installation height of the insulation vent block 40, absorbing errors in the height direction of the civil works, ensuring a level installation of the insulation vent block 40 and preventing localized warping.

[0057] The adjustment assembly 60 includes a locking member 61 and a movable plate 62. The movable plate 62 and / or the connecting plate 52 have longitudinally extending strip holes 63. The locking member 61 passes through the strip holes 63 and movably connects the movable plate 62 and the connecting plate 52. The insulating exhaust block 40 is installed on the movable plate 62.

[0058] In one embodiment, such as Figure 5 As shown, the strip-shaped hole 63 is provided on the movable plate 62. One end of the locking member 61 passes through the connecting plate 52, and the other end passes through the strip-shaped hole 63 through the movable plate 62 and is tightened and locked, realizing the movable connection between the movable plate 62 and the connecting plate 52. The locking member 61 can slide within the strip-shaped hole 63, thereby allowing the movable plate 62 to have a movable displacement relative to the connecting plate 52. When the ground is uneven, the position of the movable plate 62 relative to the connecting plate 52 is finely adjusted so that the position of the insulating exhaust block 40 adapts to the civil engineering height error. After determining the installation height, the locking member is tightened to lock the movable plate 62 and the connecting plate 52. In another embodiment, the strip-shaped hole 63 can also be formed on the connecting plate 52.

[0059] The longitudinal diameter of the strip hole 63 is set to 30mm-40mm, so that the height of the insulating exhaust block 40 can be adjusted up and down to absorb the error range of the civil engineering height of ±15mm.

[0060] The insulating exhaust block 40 is made of rubber material and can be bonded and fixed to the movable plate 62 in advance through a vulcanization process, or it can be connected and fixed through other bonding processes.

[0061] In this embodiment, since the width of the shielding door 200 is relatively long, the length of the corresponding insulating exhaust block 40 is usually 2m-4m. Therefore, multiple movable plates 62 can be set. The multiple movable plates 62 are evenly distributed on the insulating exhaust block 40 along the length direction, providing movable connection and balanced support for the insulating exhaust block 40.

[0062] The height H of the insulating exhaust block 40 is within a certain range, and the width of the insulating exhaust block 40 is within a certain range, so that it can be adapted to the use of various construction sites. Of course, the design can also be adjusted according to actual construction needs.

[0063] like Figure 1 and Figure 2 As shown, to reduce construction difficulty and improve insulation capacity, the insulation module is divided into multiple insulation units 10. The insulation module also includes insulation baffles 20. L-shaped insulation baffles 20 are installed between the shielding door 200 and the insulation units 10, and between adjacent insulation units 10. Insulating rolls 30 are also laid between adjacent insulation units 10 and between the shielding door 200 and the insulation module 100, and are laid in close contact with the L-shaped insulation baffles 20. Each insulation unit 10 is wrapped with insulating rolls 30 on all four sides and the bottom, improving insulation performance. The surrounding insulation baffles 20 further enhance insulation performance. The vertically laid insulating rolls 30 are positioned and fixed by the insulation baffles 20, preventing displacement of the insulating rolls 30 during installation.

[0064] Specifically, the insulating baffle 20 is set in an L-shape. In this way, the insulating baffle 20 can be abutted and fixed to the platform leveling layer 12 through its own L-shaped structure, and the other side can be used to install and position the insulating roll 30, thus realizing two functions.

[0065] This application addresses the shortcomings of existing insulation modules, such as long construction time and complex construction steps, by providing a construction method for a shielded door insulation module, wherein the shielded door insulation module is the insulation module 100 described in the above embodiments.

[0066] like Figure 7 The construction method for the shielded door insulation module 100 includes:

[0067] S11: Lay a platform leveling layer 12 on the platform structure layer 11. Due to construction reasons, it is difficult to achieve a smooth surface on the platform structure layer 11. In order to prevent damage to the insulating roll 30, a platform leveling layer 12 is laid on the platform structure layer 11 to ensure that the ground where the insulating roll 30 is laid is clean and flat.

[0068] S12: Provide an insulating vent block 40, on which a longitudinally extending through vent hole 41 is pre-opened, and the insulating vent block 40 is embedded in the gap between the insulating module 100 and the platform non-insulated area 300 and close to the side wall of the platform non-insulated area 300.

[0069] S13: Provide an insulating roll 30, which is laid vertically between the insulating module 100 and the platform non-insulated area 300, and the insulating roll 30 is extended horizontally on the platform leveling layer 12. The top edge of the insulating roll 30 located between the insulating module 100 and the platform non-insulated area 300 is in contact with the insulating vent block 40, and the top edge of the insulating roll 30 and the insulating vent block 40 are set at a height lower than the surface of the finishing layer 14.

[0070] S14: Provide concrete mortar and lay the concrete mortar horizontally on the insulating roll 30 above the platform leveling layer 12 to form a concrete bonding layer 13.

[0071] S16: Provide a stone slab and lay the stone slab on the uncured concrete bonding layer 13 to form a finishing layer 14;

[0072] S17: After the concrete bonding layer 13 has solidified, seal the gap between the insulating module 100 and the non-insulated area 300 of the platform.

[0073] It should be noted that in steps 13 and 14, concrete mortar is simultaneously laid on the insulating roll 30 while laying the insulating roll 30 to prevent the insulating roll from shifting or being damaged.

[0074] In this construction method, the top edge of the insulating roll 30 laid between the insulating module 100 and the non-insulated area 300 of the platform is directly connected and positioned to the insulating vent block 40. The top edge of the insulating roll 30 is lower than the decorative layer 14 and the insulating vent block 40 has a venting function. Therefore, the insulating roll 30 does not need to be pre-reserved for a flange, which can eliminate the step of flange cutting in the later stage. It also avoids the problem of the insulating roll 30 being scratched or torn during the construction process, affecting the insulation performance. More importantly, by eliminating the flange of the insulating roll 30, the subsequent station decoration, equipment installation and commissioning stages can be carried out directly after the decorative layer 14 is laid. The overall construction time of the station is significantly shortened, and the laying of high-quality insulating modules is achieved in one go.

[0075] In one embodiment, the insulating vent block 40 is positioned 1mm-2mm below the surface of the finishing layer 14. This can be adjusted according to construction requirements; for example, the height difference between the top edge and the surface of the finishing layer 14 can be 2mm-3mm.

[0076] In one embodiment, the construction method further includes:

[0077] S21: Provide an insulating baffle 20, and install the insulating baffle 20 between the shielding door 200 and the insulating unit 10, and between adjacent insulating units 10 respectively;

[0078] S22: Provide an insulating roll 30, lay the insulating roll 30 vertically between the shielding door 200 and the insulating unit 10, between adjacent insulating units 10, and fix it on the insulating baffle 20, and extend the insulating roll 30 horizontally onto the platform leveling layer 12.

[0079] S23: After the concrete bonding layer 13 has solidified, seal the gaps between the shielding door 200 and the insulating unit 10, and between adjacent insulating units 10.

[0080] In the above embodiments, step S21 can be implemented simultaneously with step S12, or they can be implemented separately without any order. There is also no absolute order between steps S22 and S13. The insulating roll 30 is usually a rectangular roll. Therefore, during construction, steps S22 and S13 can be laid using the same insulating roll 30. One end is laid vertically between the shielding door 200 and the insulating unit 10, and the other end extends and is laid vertically between the insulating unit 10 and the non-insulated area 300 of the platform in the opposite direction after being laid on the platform leveling layer 12. Similarly, there is no order between steps S23 and S17.

[0081] In one embodiment, step S22, "providing an insulating roll 30, laying the insulating roll 30 vertically between the shielding door 200 and the insulating unit 10, between adjacent insulating units 10, and fixing it to the insulating baffle 20," includes: the insulating roll 30 has a pre-formed flange; after laying the stone, the flange extending beyond the surface of the stone is cut. Since there is no step of releasing moisture between the insulating units and at the shielding door 200, the insulating roll 30 can have a pre-formed flange. The pre-formed flange can be cut directly after the stone is laid, without waiting for the concrete adhesive layer 13 to dry, thus not affecting subsequent construction and having no impact on construction time. Of course, the flange can also be omitted, and the top edge of the insulating roll 30 can be lower than the surface of the finishing layer 14 during laying.

[0082] In steps S23 and S17, insulating sealant 70 is provided. After the concrete bonding layer 13 has solidified, the insulating sealant 70 is filled into the gaps between the insulating module and the non-insulated area 300 of the platform, between the shielding door 200 and the insulating unit 10, and between adjacent insulating units 10 to achieve sealing.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
