Description

Technical Field

[0001] This invention relates to the field of evacuation platform technology, specifically to modular splicing evacuation platform composite panels and their manufacturing process. Background Technology

[0002] In scenarios such as rail transit, tunnels, and large buildings, evacuation platforms are critical facilities for ensuring the emergency evacuation of personnel. Traditional evacuation platform composite panels are simply fastened to the support below with bolts. While this method is simple to operate and has high installation efficiency, the joints between adjacent panels lack reinforcement design. Under long-term load-bearing or external impact, the joints can easily become weak points, affecting the stability of the connection and the reliability of the load-bearing capacity.

[0003] Therefore, we propose a modular splicing evacuation platform composite panel and its production process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a modular splicing evacuation platform composite panel and its manufacturing process, which overcomes the deficiencies of existing technologies, has a reasonable design, is easy to install, and solves the technical problem that the splicing parts of existing panels are prone to becoming weak points in strength, affecting the connection stability and load-bearing reliability.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A modular, interlocking evacuation platform composite panel includes a panel body, characterized in that: a pair of sleeves are provided on both sides of the panel body, the sleeves are T-shaped and include a vertical guide sleeve and a horizontal guide sleeve that are interconnected, a driving block is slidably installed in the vertical guide sleeve, the driving block has a through hole in the vertical direction, a first driven block is slidably installed in the horizontal guide sleeve on one side, and a second driven block is slidably installed in the horizontal guide sleeve on the other side, a positioning tenon is formed on the outer side of the first driven block, and a positioning groove is formed on the outer side of the second driven block, at the splicing point of two adjacent composite panels, a locking bolt passes through the through hole and fixes the composite panel to the lower support, during the downward tightening of the locking bolt of one composite panel can drive the positioning tenon of the first driven block to extend and insert into the horizontal guide sleeve of the other composite panel through the driving block, and during the downward tightening of the locking bolt of the other composite panel can drive the positioning groove of the second driven block to fit over the positioning tenon through the driving block.

[0007] Furthermore, a first inclined surface is provided below the driving block, and the main bodies of the first driven block and the second driven block are each provided with a pair of inclined wedges extending toward one side of the driving block. The gap between the pair of inclined wedges is used for the locking bolt to pass through, and a second inclined surface that fits against the first inclined surface is provided above the inclined wedges.

[0008] The first driven block and the second driven block are pushed outward laterally by the first elastic member;

[0009] The drive block is elastically mounted vertically upwards via a second elastic element.

[0010] The upper part of the main body is provided with a long groove extending along the length of the transverse guide sleeve. A first limiting rod is vertically installed at one end of the long groove away from the drive block, and a second limiting rod is provided at the other end. The second limiting rod is vertically installed in the transverse guide sleeve. The first elastic element is a first tension spring, and the two spring feet of the first tension spring are respectively hung on the first limiting rod and the second limiting rod.

[0011] The second elastic element is a second spring, which is sleeved on the locking bolt and its two ends abut against the bottom wall of the driving block and the vertical guide sleeve, respectively.

[0012] Furthermore, the upper and / or lower edge of the positioning groove is provided with a flipping drive part, the lower side of the flipping drive part is provided with a third inclined surface, and a locking plate is rotatably provided on the upper and / or lower side wall of the transverse guide sleeve. The locking plate is flipped to the adjacent side wall by a third elastic element, and the upper side of the locking plate is provided with a fourth inclined surface that cooperates with the third inclined surface.

[0013] A locking groove is provided between the positioning tenon and the main body. When the positioning groove is pushed outward, the flipping drive unit drives the locking plate to flip and abut against the locking groove to prevent the positioning tenon from coming out.

[0014] Furthermore, the third elastic element is a third torsion spring, and torsion springs are sleeved on the rotating shafts at both ends of the locking plate. One spring leg of the torsion spring hooks onto the side wall of the positioning groove, and the other spring leg hooks onto the locking plate.

[0015] Furthermore, a limiting protrusion ring is detachably installed at the upper end of the vertical guide sleeve, and the sealing and encapsulation is achieved by the upper end of the horizontal guide sleeve opening and abutting against the limiting protrusion ring.

[0016] Furthermore, the upper and lower ends of the vertical guide sleeve are folded outward to form flanges.

[0017] Furthermore, T-shaped reinforcing members (e.g., T-bolts) are distributed on the outer walls of the vertical guide sleeve and the horizontal guide sleeve.

[0018] Furthermore, reinforcing members are laid inside the plate.

[0019] Furthermore, the reinforcing member is a steel mesh.

[0020] Furthermore, the perforated cross-section is waist-shaped.

[0021] The production method of the above-mentioned modular splicing evacuation platform composite panel is characterized by including the following steps:

[0022] S1. Laying of steel mesh: Place the steel mesh inside the mold and support it on the pads;

[0023] S2. Placement of the sleeve: Place the sleeve inside the mold. Insert positioning rods into the upper opening of the vertical guide sleeve and the outer opening of the horizontal guide sleeve for positioning and sealing. The bottom wall of the vertical guide sleeve is fixed to the mold with bolts.

[0024] S3. Material pouring: The pouring material is evenly poured into the mold and then vibrated.

[0025] S4. Press anti-slip texture: Press anti-slip texture on the upper surface of the board while it is still wet.

[0026] This invention provides a modular, interlocking evacuation platform composite panel and its manufacturing process, which has the following beneficial effects:

[0027] 1. The drive block and driven block inside the sleeve cooperate with each other. When the locking bolt is tightened downward to fix the plate, the drive positioning tenon connects with the positioning groove. No separate splicing operation is required. The splicing and fixing are completed simultaneously, ensuring the original construction efficiency.

[0028] 2. The splicing structure requires no additional auxiliary tools. When a single panel is damaged, it can be replaced by simply removing the corresponding locking bolts without affecting the surrounding panels, thus significantly reducing maintenance costs.

[0029] 3. After the positioning tenon is aligned with the positioning groove, the flipping drive unit drives the locking plate to engage with the locking groove, forming a double fixation of tenon and mortise joint and mechanical locking, which effectively prevents dislodgement or loosening caused by vibration and impact; at the same time, the elastic pre-tightening design of the first elastic element, the second elastic element and the third torsion spring can enable the relevant components to automatically reset, making disassembly convenient.

[0030] 4. The slab has a built-in steel mesh and T-shaped reinforcements on the outside of the sleeve, which further improves the overall load-bearing strength and structural stability, and effectively ensures the service life of the composite slab. Attached Figure Description

[0066] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0067] See attached document Figure 1-8 A modular, interlocking evacuation platform composite panel includes a panel body 1. A pair of sleeves 3 are provided on both sides of the panel body 1. Each sleeve 3 is T-shaped and includes a vertically connected guide sleeve 41 and a horizontally connected guide sleeve 42. A driving block 5 is slidably installed vertically inside the vertically connected guide sleeve 41. The driving block 5 has a through-hole with a waist-shaped cross-section. A first driven block is slidably installed horizontally inside one side of the horizontally connected guide sleeve 42, and a second driven block is slidably installed horizontally inside the other side of the horizontally connected guide sleeve 42. A positioning tenon 74 is formed on the outer side of the driving block, and a positioning groove 72 is formed on the outer side of the second driven block. At the joint of two adjacent composite panels, the locking bolt 6 passes through the through hole and fixes the composite panel to the lower bracket. When the locking bolt 6 of one composite panel is tightened downward, it can drive the positioning tenon 74 of the first driven block to extend through the driving block 5 and insert into the transverse guide sleeve 42 of the other composite panel. When the locking bolt 6 of the other composite panel is tightened downward, it can drive the positioning groove 72 of the second driven block to be sleeved on the outside of the positioning tenon 74 through the driving block 5.

[0068] In this embodiment, a first inclined surface 5a is provided below the driving block 5, and the main bodies 71 of the first driven block and the second driven block are each provided with a pair of inclined wedges 73 extending toward one side of the driving block 5. The gap 73b between the pair of inclined wedges 73 is used for the locking bolt 6 to pass through. A second inclined surface 73a that fits with the first inclined surface 5a is provided above the inclined wedges 73. The first driven block and the second driven block are pushed outward in the lateral direction by a first elastic member. The driving block 5 is elastically pushed upward in the vertical direction by a second elastic member.

[0069] Specifically, the upper part of the main body 71 is provided with a long groove 71a extending along the length direction of the transverse guide sleeve 42. A first limiting rod 11 is vertically installed at one end of the long groove 71a away from the driving block 5, and a second limiting rod 12 is provided at the other end. The second limiting rod 12 is vertically installed in the transverse guide sleeve 42. The first elastic element is a first tension spring 8. The two ends of the first tension spring 8 are respectively hooked on the first limiting rod 11 and the second limiting rod 12 (during the outward movement of the positioning tenon 74 and the positioning groove 72, the two ends of the first tension spring are always hooked on the first limiting rod 11 and the second limiting rod 12). Figure 8 The detachment is only due to the lack of stretching during assembly of the parts shown in the figure and does not affect actual use); the second elastic element is the second spring 9, which is sleeved on the locking bolt 6 and its two ends abut against the bottom wall of the drive block 5 and the vertical guide sleeve 41, respectively.

[0070] As the locking bolt 6 is screwed down and connected to the lower support thread, it will drive the driving block 5 to move down against the action of the second spring 9. Since the driving block 5 and the first and second driven blocks are engaged through the first and second inclined surfaces 73a, it will drive the first and second driven blocks to move laterally. The positioning tenon 74 of the first driven block extends out and inserts into the lateral guide sleeve 42 of the other composite board being spliced, and drives the positioning groove 72 of the second driven block to be fitted onto the positioning tenon 74, so that the adjacent boards 1 are automatically aligned when spliced, reducing the appearance of steps and reducing the risk of tripping during evacuation.

[0071] The composite panels in this solution are highly versatile and suitable for various application scenarios: the modular design allows the panels 1 to be flexibly spliced ​​according to different scenario requirements, and is suitable for laying evacuation platforms of different sizes such as rail transit tunnels, large buildings, and underground spaces; the sleeves and their internal components can be pre-embedded in the mold during the pouring of the panels 1, which reduces on-site installation in the later stage and reduces the labor intensity during transportation and installation.

[0072] In this embodiment, a front end blocking ring 42a is formed by protruding inward at the end of the positioning groove 72. The front end blocking ring 42a guides the positioning tenon 74 (the end of the positioning tenon 74 is chamfered) for rough positioning, and then the positioning groove 72 and the positioning tenon 74 are finely positioned. The upper edge and / or lower edge of the positioning groove 72 are provided with a flipping drive part 72a protruding outward. The lower side of the flipping drive part 72a is provided with a third inclined surface 72b. A locking plate 10 is rotatably provided on the upper side wall and / or lower side wall of the transverse guide sleeve 42. The locking plate 10 is disposed between the front end blocking ring 42a and the flipping drive part 72a. The locking plate 10 is flipped to the adjacent side wall by a third elastic element, preferably flipped to be horizontal with the side wall to avoid interference when the positioning tenon 74 is inserted. The upper side of the locking plate 10 is provided with a fourth inclined surface 10a that cooperates with the third inclined surface 72b.

[0073] A locking groove 74a is provided between the positioning tenon 74 and the main body 71. When the positioning groove 72 is pushed outward, the flipping drive unit 72a drives the locking plate 10 to flip and abut against the locking groove 74a to prevent the positioning tenon 74 from coming out.

[0074] Specifically, the third elastic element is a third torsion spring. The torsion spring is sleeved on the rotating shafts at both ends of the locking plate 10. One spring leg of the torsion spring hooks onto the side wall of the positioning groove 72, and the other spring leg hooks onto the locking plate 10.

[0075] In this embodiment, a limiting protrusion ring is detachably installed at the upper end of the vertical guide sleeve 41, and the cover 4 is encapsulated by the upper opening of the horizontal guide sleeve 42 and abutting against the limiting protrusion ring.

[0076] In this embodiment, the upper and lower ends of the vertical guide sleeve 41 are folded outward to form flanges, and T-shaped reinforcing members, such as T-bolts, are distributed on the outer side walls of the vertical guide sleeve 41 and the horizontal guide sleeve 42, which can effectively improve the bonding strength between the sleeve and the casting plate 1.

[0077] In this embodiment, a reinforcing member is laid inside the plate 1, and the reinforcing member is a steel mesh 2.

[0078] The production method of the above-mentioned modular splicing evacuation platform composite panel is characterized by including the following steps:

[0079] S1. Laying of steel mesh 2: Place steel mesh 2 inside the mold and support it on the pad;

[0080] S2. Placement of the sleeve: Place the sleeve inside the mold. Insert positioning rods into the upper opening of the vertical guide sleeve 41 and the outer opening of the horizontal guide sleeve 42 for positioning and sealing. The bottom wall of the vertical guide sleeve 41 is fixed to the mold by bolts.

[0081] S3. Material pouring: The pouring material is evenly poured into the mold and then vibrated.

[0082] S4. Press anti-slip texture: While the board 1 is not dry, press anti-slip texture on the upper surface of the board 1 (the pressing and shape of the anti-slip texture is existing technology and can be flexibly selected as needed, and is not shown on the board 1 in the figure).

[0083] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
