Description

Technical Field

[0001] This utility model relates to the field of road and bridge municipal signage, specifically to a combined structure temporary road and bridge municipal signage device. Background Technology

[0002] In road and bridge construction and municipal engineering projects, or during temporary traffic control scenarios, temporary directional signs are crucial facilities for ensuring on-site traffic order and guiding the safe passage of pedestrians and vehicles. Currently, the structural design of existing temporary directional signage devices for roads and bridges has significant limitations. Most temporary signs have their supports and the signboards or panels supporting the directional text fixed together as a single unit using bolts or welding. When changes occur in the construction phase or adjustments to traffic control information necessitate changing the directional text or content, the signboards cannot be disassembled for modification; the entire signage system must be replaced. This results in significant material waste, low adjustment efficiency, and difficulty in adapting to dynamically changing on-site needs.

[0003] Moreover, because the device is a fixed, integrated structure that cannot be disassembled or folded, its overall size is quite large. During transportation, it not only occupies a lot of transport space and increases transportation costs, but it is also prone to damage to signs or supports due to collisions. It also requires a large amount of space for storage, which is not conducive to on-site temporary storage management, especially in construction site scenarios where space is limited. Utility Model Content

[0004] This invention addresses the problem that existing temporary road and bridge signage devices cannot be individually disassembled for modification when changes in construction phases or adjustments to control information require changes to the font or content of the signs, necessitating the replacement of the entire signage system, which leads to significant material waste. Therefore, this invention provides a combined structure temporary road and bridge signage device.

[0005] The technical solution of this utility model is:

[0006] A combined structure temporary road and bridge municipal signage device includes a signage mounting base plate, unit insert plates, an inner support frame, and an outer support frame;

[0007] The top ends of the inner and outer support frames are rotatably connected by a rotating shaft assembly, forming a herringbone structure. The sign mounting base plate is connected to the inclined surface of the inner support frame by an upper and lower insertion method, and the sign mounting base plate is supported by the two inner support frames.

[0008] The sign mounting base plate is evenly provided with a set of insertion holes, and the set of insertion holes are arranged in two rows longitudinally on the sign mounting base plate.

[0009] The back of the unit insert plate is provided with two rotating hook plates, which are symmetrically arranged. The hook plates are inserted into the insert holes of the sign mounting base plate to insert a set of unit insert plates into the sign mounting base plate.

[0010] Furthermore, the marking mounting base plate has a rectangular structure, and the bottom of the marking mounting base plate has symmetrically opened slots with a triangular notch structure at the bottom.

[0011] Furthermore, a front insert plate that matches the slot is mounted on the front of the inner support frame;

[0012] The front insert plate consists of a triangular steel plate and a rectangular steel plate, which are vertically welded together. The slot at the bottom of the sign mounting base plate is inserted into the front insert plate, so that the sign mounting base plate and the inner support frame are connected by sliding insertion.

[0013] Furthermore, the unit insert plate has a rectangular structure, and the back of the unit insert plate has a groove-shaped structure. The true surface of the unit insert plate is pressed with an indicator mark protrusion, and the protrusion is painted.

[0014] Furthermore, the unit insert plate also includes a fixed shaft, a sleeve, an upper baffle, and a lower baffle;

[0015] The sleeve is fixedly connected to the hook plate. The top and bottom of the fixed shaft are perpendicularly connected to the top and bottom plates of the unit insert plate, respectively. The sleeve is inserted into the fixed shaft. The upper baffle and the lower baffle are fixedly connected to the fixed shaft, and the upper baffle and the lower baffle are arranged parallel to each other on the fixed shaft. The sleeve is set between the upper baffle and the lower baffle to limit the movement of the sleeve. The sleeve drives the hook plate to rotate on the fixed shaft, so that the hook plate rotates into the unit insert plate when it rotates.

[0016] Furthermore, the inner support frame also includes a insert shaft and an inner hanging ring;

[0017] The insertion shaft is vertically and fixedly connected to the side of the inner support frame, and the rear of the inner support frame is fixedly connected to the inner hanging ring.

[0018] Furthermore, the outer support frame also includes a bushing and an outer hanging ring;

[0019] The bushing is fixed to the top of the outer support frame, and the outer hanging ring is fixedly connected to the back of the outer support frame. The bushing contains the insert shaft of the inner support frame, which drives the inner support frame to rotate.

[0020] Furthermore, a chain is installed between the inner hanging ring on the inner support frame and the outer hanging ring on the outer support frame, and the chain pulls the inner support frame and the outer support frame to a limited position.

[0021] Furthermore, it also includes a rear insert plate and a reinforcing plate;

[0022] The rear insert plate is fixedly connected to the outer support frame. The bottom of the reinforcing plate has a slot with the same triangular notch structure as the bottom of the marking mounting base plate, and the slot on the reinforcing plate is inserted into the rear insert plate.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] This invention reduces material waste and improves adjustment efficiency. The unit insert plate and the sign installation base plate are connected by an insert. When the construction stage changes or the control information needs to be adjusted, there is no need to replace the entire device. Only the corresponding unit insert plate needs to be disassembled for modification or replacement, reducing material waste and significantly improving the efficiency of information adjustment to adapt to dynamic on-site needs. If the original instruction to carry out construction on the left lane needs to be changed to construction on the right lane, the old device needs to be completely removed and a whole new set of signs needs to be replaced, wasting one set of devices (costing about 500 yuan) and requiring two people and 30 minutes for replacement. This new invention only requires disassembling the corresponding unit insert plate on the left and replacing it with the unit insert plate on the right, costing only 50 yuan, with each insert plate costing about 15 yuan. It can be completed by one person in 5 minutes, reducing material waste by 90%.

[0025] This invention facilitates transportation and storage. The components of the device employ detachable connection structures such as insert-type and rotating-type, allowing for disassembly and folding, significantly reducing the overall size. During transportation, it saves space, reduces transportation costs, and minimizes the risk of collision damage. Storage requires minimal space, making it particularly suitable for construction sites with limited space, facilitating temporary storage management. It can be stacked in a corner of a temporary construction warehouse, requiring only 1m² of space, avoiding encroachment on construction site workspace.

[0026] This utility model provides stable support. The inner and outer support frames form a herringbone structure, with chain limiting and reinforcement plates for additional support, resulting in strong overall stability and ensuring traffic order and safety. Meanwhile, the sign mounting base plate and...

[0027] The unit plates are connected by a combination method, and the two slots at the bottom of the marking mounting base plate are inserted into the front plate on the inner support frame, which allows for quick installation of the marking mounting base plate and the inner support frame.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Specific implementation method one:

[0047] Combination Figure 1 — Figure 12 This embodiment describes a combined structure temporary road and bridge municipal signage device, which includes a signage mounting base plate 1, a unit insert plate 2, an inner support frame 3, and an outer support frame 4.

[0048] The top ends of the inner support frame 3 and the outer support frame 4 are rotatably connected by a rotating shaft assembly, so that the inner support frame 3 and the outer support frame 4 form a herringbone structure. The sign mounting base plate 1 and the inclined surface of the inner support frame 3 are connected by an upper and lower insertion method, and the sign mounting base plate 1 is supported by the two inner support frames 3.

[0049] The sign mounting base plate 1 is evenly provided with a set of insert plate holes 11, and the set of insert plate holes 11 are arranged in two rows longitudinally on the sign mounting base plate 1.

[0050] The back of the unit insert plate 2 is provided with two rotating hook plates 21, and the two hook plates 21 are symmetrically arranged. The hook plates 21 are inserted into the insert plate insertion holes 11 of the marking mounting base plate 1, so as to insert a set of unit insert plates 2 into the marking mounting base plate 1.

[0051] The insert shaft can rotate 360° within the bushing, ensuring that the inner and outer support frames can be flexibly adjusted in angle and finally fixed in a herringbone structure. The inner and outer support frames are usually angled at 60-90° to ensure support stability.

[0052] The spacing between the sockets 11 of a set of plug-in boards is 5-10cm, determined according to the size of the unit plug-in board 2. The number of sockets in each row is the same to ensure that the unit plug-in boards 2 can be neatly assembled to form complete instructions after installation. After the hook plate 21 is inserted into the socket 11, it slides a short distance within the socket 11, thus locking the hook plate 21 of the unit plug-in board 2 into the socket 11 and preventing the unit plug-in board 2 from falling off. During disassembly, the unit plug-in board 2 can be easily pulled out by lifting it upwards, without the need for tools. Specific Implementation Method Two:

[0054] Combination Figure 1 — Figure 12 This embodiment describes a combined structure temporary road and bridge municipal signage device. The signage mounting base plate 1 has a rectangular structure, and the bottom of the signage mounting base plate 1 has symmetrically opened slots 12 with a triangular notch structure at the bottom.

[0055] The base plate 1 for sign installation is designed to conform to the standard dimensions of municipal signs. The side length of the base plate 1 is usually 1.2m × 0.8m (length × height), and the thickness is 3-5mm (metal material, such as galvanized steel plate), which ensures strength while reducing weight.

[0056] The triangular notch at the bottom of the mounting base plate 1 serves to quickly position the device during insertion, preventing misalignment. The triangular structure also distributes the force, preventing the edges of the slot from deforming due to long-term load. Specific implementation method three:

[0058] Combination Figure 1 — Figure 12 This embodiment describes a combined structure temporary road and bridge municipal signage device, wherein the front of the inner support frame 3 is equipped with a front insert plate 31 that matches the slot 12.

[0059] The front insert plate 31 is composed of a triangular steel plate and a rectangular steel plate. The rectangular steel plate and the triangular steel plate are welded together vertically. The slot 12 at the bottom of the marking mounting base plate 1 is inserted into the front insert plate 31, so that the marking mounting base plate 1 and the inner support frame 3 are connected by sliding insertion.

[0060] The length of the right-angled side of the triangular steel plate is consistent with the depth of the slot 12, the height of the rectangular steel plate matches the height of the inclined surface of the inner support frame 3, and the width is the same as the thickness of the sign mounting base plate 1, ensuring no looseness or gaps after insertion. During installation, first align the bottom slot 12 of the sign mounting base plate 1 with the top of the front insert plate 31, and slide it down the inclined surface of the inner support frame 3 until the slot 12 completely covers the front insert plate 31. No bolts are required throughout the process, and installation can be completed by one person in 1-2 minutes. Specific implementation method four:

[0062] Combination Figure 1 — Figure 12 This embodiment describes a combined structure temporary road and bridge municipal signage device. The unit insert 2 has a rectangular structure and a groove-shaped back. The front of the unit insert 2 has a raised indicator mark, and the raised mark is painted.

[0063] The groove depth of the back of the unit insert plate 2 is about 2-3cm. The groove width matches the size of components such as hook plate 21 and fixed shaft 22, which can just accommodate all rotating structures and prevent the components from being exposed and damaged by collision.

[0064] The front of Unit Insert 2 has raised indicator markings with a height of about 1-2mm, which can be pressed with commonly used signs or text such as "Turn Left", "Speed ​​Limit 30" and "Construction Area". The paint is high reflective paint (such as yellow background with black text or red background with white text), which can reflect light under nighttime lighting to improve visibility. Specific implementation method five:

[0066] Combination Figure 1 — Figure 12 This embodiment describes a combined structure temporary road and bridge municipal signage device, wherein the unit insert plate 2 further includes a fixed axis 22, a sleeve 23, an upper baffle 24, and a lower baffle 25;

[0067] The sleeve 23 is fixedly connected to the hook plate 21. The top and bottom of the fixed shaft 22 are perpendicularly connected to the top and bottom plates of the unit insert plate 2, respectively. The sleeve 23 is inserted into the fixed shaft 22. The upper baffle 24 and the lower baffle 25 are fixedly connected to the fixed shaft 22, and the upper baffle 24 and the lower baffle 25 are arranged in parallel on the fixed shaft 22. The sleeve 23 is positioned between the upper baffle 24 and the lower baffle 25 to limit the movement of the sleeve 23. The sleeve 23 drives the hook plate 21 to rotate on the fixed shaft 22, so that the hook plate 21 rotates into the unit insert plate 2 when it rotates.

[0068] The fixed shaft 22 has a diameter of about 8-10mm and a length that matches the height of the unit insert plate 2; the inner diameter of the sleeve 23 is slightly larger than the diameter of the fixed shaft, with a gap of 0.5mm to ensure smooth rotation; the hook plate 21 can rotate 90° around the fixed shaft 22.

[0069] The upper baffle 24 and the lower baffle 25 are circular steel plates with a diameter of 15mm. The spacing between them is the same as the length of the sleeve, which can just hold the sleeve in place and prevent it from moving up and down. Specific implementation method six:

[0071] Combination Figure 1 — Figure 12 This embodiment describes a combined structure temporary road and bridge municipal signage device, wherein the inner support frame 3 further includes an insert shaft 32 and an inner hanging ring 33;

[0072] The insert shaft 32 is vertically and fixedly connected to the side of the inner support frame 3, and the rear of the inner support frame 3 is fixedly connected to the inner hanging ring 33.

[0073] The insert shaft 32 is fixed to the top side of the inner support frame 3, ensuring that it can be inserted into the bushing 41 of the outer support frame 4 with sufficient room for rotation. The inner hanging ring 33 is a circular iron ring with a diameter of 5cm, fixed in the middle of the rear of the inner support frame 3 for easy hooking of the chain. The inner support frame 3 is a metal square tube with a cross-section of 4cm×4cm welded together. Specific implementation method seven:

[0075] Combination Figure 1 — Figure 12 This embodiment describes a combined structure temporary road and bridge municipal signage device, wherein the outer support frame 4 further includes a bushing 41 and an outer hanging ring 42;

[0076] The bushing 41 is fixed to the top of the outer support frame 4, and the outer hanging ring 42 is fixedly connected to the back of the outer support frame 4. The bushing 41 is inserted with the insert shaft 32 of the inner support frame 3, and the insert shaft 32 drives the inner support frame 3 to rotate.

[0077] The bushing 41 is a circular metal tube with an inner diameter slightly larger than that of the insert shaft 32. It is welded to the inner side of the top of the outer support frame 4 and corresponds to the position of the insert shaft 32 of the inner support frame 3.

[0078] The outer ring 42 has the same specifications as the inner ring 33 and is fixed in the middle of the rear of the outer support frame 4. It is at the same height as the inner ring 33 to ensure that the chain 5 can remain horizontal and be evenly stressed after installation.

[0079] The outer support frame 4 has a similar structure to the inner support frame 3. When the two are combined into a V-shape, the outer support frame 4 tilts outward and forms a certain angle with the ground. This angle is about 60°, which enhances the wind resistance of the device. Detailed implementation method eight:

[0081] Combination Figure 1 — Figure 12 This embodiment describes a combined structure temporary road and bridge municipal signage device. A chain 5 is installed between the inner hanging ring 33 on the inner support frame 3 and the outer hanging ring 42 on the outer support frame 4. The chain 5 pulls the inner support frame 3 and the outer support frame 4 to a limited position.

[0082] Chain 5 is a regular iron chain with a pitch of 2cm and an adjustable length. The two ends are connected to the inner hanging ring 33 and the outer hanging ring 42 respectively via hooks. When the inner and outer support frames are adjusted to the optimal angle of the herringbone shape, the chain 5 is tightened and fixed to limit the rotation of both and prevent the angle from increasing or the device from tipping over due to wind or collision. Specific implementation method nine:

[0084] Combination Figure 1 — Figure 12 This embodiment describes a combined structure temporary road and bridge municipal signage device, which also includes a rear insert plate 6 and a reinforcing plate 7.

[0085] The rear insert plate 6 is fixedly connected to the outer support frame 4. The bottom of the reinforcing plate 7 is provided with a slot 12 with the same triangular notch structure as the bottom of the marking mounting base plate 1, and the slot 12 on the reinforcing plate 7 is inserted into the rear insert plate 6.

[0086] The rear insert plate 6 is identical in specifications to the front insert plate 31 and is welded to the crossbar of the outer support frame 4. The reinforcing plate 7 is a rectangular metal plate with the same dimensions as the sign mounting base plate 1 and a thickness of 3mm. The bottom slot 12 is perfectly matched with the slot 12 of the sign mounting base plate 1. After the rear insert plate 6 is inserted, the reinforcing plate 7 and the sign mounting base plate 1 form a herringbone structure, providing auxiliary support from the rear to prevent the sign mounting base plate 1 from bending due to uneven stress.
