[0003] Currently, various signboards in urban rail transit systems are mostly installed using pre-buried foundations to ensure they do not intrude upon clearances and ensure safe installation of equipment. These pre-buried foundations must be reserved during the civil construction phase. However, during actual construction, these foundations are often overlooked, and the subsequent installation positions are adjusted. This leads to increased costs and delays in subsequent repairs or relocations. Sometimes, clearances can even lead to insufficient space for the pre-buried foundations. Optimizing construction workflows, coordinating the interface between civil engineering and post-station engineering, and reducing the amount of pre-buried structural foundations required for civil construction are key factors in determining construction quality and timeliness.

[0024] like Figure 1-Figure 4 As shown, the utility model provides a special clamping device for quick-install traffic signs, which is used for the rapid installation of urban rail transit signs, including two U-shaped slots 1 arranged parallel and spaced relative to each other on an existing underground I-beam 8, a vertical support plate 2 provided on the U-shaped slot 1, a sign mounting plate 3 vertically provided on the vertical support plate 2, and a fastening screw 4 provided across the two vertical support plates 2; the utility model uses the existing I-beam structure as a basis, and performs rapid installation without destroying the rigidity and strength of the I-beam structure, providing an installation basis for such signs, with low construction period requirements, quick and convenient construction and installation, and can effectively solve the problems of tight construction period and easy invasion of equipment in urban rail transit.
[0025] Further, if Figure 1-Figure 4 As shown, the openings of the two U-shaped slots 1 are opposite to each other and are installed on the wing plates 9 of existing underground I-beams such as contact network pillars and sound barrier columns; the opening size of the U-shaped slot 1 is adapted to the thickness of the existing underground I-beam wing plates; the depth of the U-shaped slot 1 is adapted to the width b of a single wing plate; the width of the U-shaped slot 1 is 2 to 3 mm larger than the maximum thickness d of the I-beam wing plate; the length of the fastening screw 4 is determined by the waist width B of the I-beam, the effective length of the fastening screw 4 is greater than the waist width B of the I-beam, and when the clamping device is tightened, it is ensured that the nut 5 is at least 10 thread lengths away from the end of the screw; the lengths of the U-shaped slot 1, the vertical support plate 2, and the signboard mounting plate 3 are the same, and the specific dimensions depend on the lengths of different signboards 7.
[0026] Further, if Figure 1-Figure 4 As shown, the vertical support plate 2 is connected to the bottom plate of the U-shaped slot 1, and the two are integrally formed; the vertical support plate 2 is provided with a through hole 21 for the fastening screw 4 to pass through; the two U-shaped slots 1 are fixed as a whole to the existing underground I-beam 8 by the fastening screw 4 and the nut 5; the number of the fastening screws 4 and the nut 5 is determined according to the length of different signboards to ensure that the special clamping device is firmly installed; the length of the fastening screw 4 is determined according to the width of the existing underground I-beam wing plate; the signboard mounting plate 3 and the U-shaped slot 1 are respectively located on both sides of the vertical support plate 2; the signboard mounting plate 3 is provided with a reserved elliptical hole 31 for fixing the signboard; the number of the elliptical holes 31 is determined according to the number of reserved holes for installing the signboard, and the two numbers are consistent.
[0027] Further, if Figure 1-Figure 4 As shown, a stiffening rib 6 is provided between the U-shaped slot 1 and the signboard mounting plate 3 to ensure that the strength of the clamping device itself is not damaged by shearing and bending; one end of the stiffening rib 6 is connected to the open end of the U-shaped slot 1 close to the locking screw 4, and the other end is connected to the intersection of the signboard mounting plate 3 and the vertical support plate 2.
[0028] The utility model provides a method for installing a special clamping device for a quick-install traffic sign, comprising the following steps:
[0029] Step 1: Reasonably determine the length of the clamping device based on the size and quality of the installation sign;
[0030] Step 2: Lay out the lines and position them according to the installation height requirements of the design drawings, and clamp the two U-shaped slots 1 of the special clamping device on the two top wing plates 9 of the existing I-beam 8 underground;
[0031] Step 3: After adjusting the height of the two U-shaped slots 1, pass the locking screw 4 through the through-holes 21 on the two oppositely arranged vertical support plates 2 to connect the two U-shaped slots 1;
[0032] Step 4: After adjusting the locking screw 4 to the appropriate position, install nuts 5 at both ends of each locking screw 4 to ensure that the two U-shaped slots 1 of the special clamping device are firmly installed;
[0033] Step 5: Use bolts to connect the mounting holes on the signboard 7 with the reserved elliptical holes on the plane of the special clamping device to complete the installation of the signboard 7.
[0034] This utility model appropriately determines the length of the clamping device based on the size and quality of the signboard being installed. If the clamping device is too long, the number of tightening screws and stiffening ribs are increased. The clamping device is adjusted to the existing I-beam according to the signboard's height. Once the clamping device is tightened, the signboard is installed without damaging the existing structure. Urban rail transit generally uses a catenary or contact rail for power supply. Stainless steel pillars with an I-shaped cross-section are typically installed in ground and elevated sections of the track where this type of power supply is provided. Furthermore, when ground and elevated sections pass through urban areas or areas with nearby residents, noise barriers are installed on both sides of the track to reduce noise, in accordance with environmental assessment and acceptance requirements. The primary load-bearing structure of the sound barriers is typically stainless steel pillars with an I-shaped cross-section. The existing stainless steel posts for the catenary and sound barrier provide the foundation for the clamping device. Urban rail transit is expensive, and the tracks and surrounding structures are compactly arranged. To prevent equipment and facilities from encroaching on clearances, the installation of various signboards requires the casting of widening sections or the reservation of installation foundations during the civil engineering phase, further increasing project costs. This clamping device fully utilizes the existing structure without compromising its rigidity and strength, ensuring that the equipment can be installed within limits without adding a widened section. During the post-station implementation phase of urban rail transit, trackwork, line construction, sound barrier engineering, and civil engineering finishing work will be interspersed with train commissioning and comprehensive joint commissioning. The tight construction schedule means limited time for installing signage and other equipment. This clamping device does not require pre-drilling or pre-buried foundations in the existing structure. By determining the size of the clamping device's U-shaped slot based on the existing I-beam's wing plate dimensions, installation can be quick and easy, shortening the project installation period and reducing exposure risks in the track area.
[0035] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
