Description

Technical Field

[0001] This utility model relates to the field of expansion joint technology, and more specifically, to a passageway for expansion joints in roofs with varying spans. Background Technology

[0002] In the construction industry, due to changes in environmental factors such as temperature and humidity, building structures will experience thermal expansion and contraction, leading to cracking or deformation. Therefore, the installation of expansion joints is necessary. They provide space for deformation in buildings and effectively prevent damage caused by structural deformation. Currently, for waterproofing expansion joints, existing technologies usually use staggered overlapping cover plates on the building foundation structure on both sides of the expansion joint to cover the expansion joint and prevent rainwater intrusion. However, in the case of roofs with varying spans, such expansion joints themselves present the problem of inconvenience for passage. Furthermore, the installed cover plates are prone to deformation due to frequent foot traffic during long-term use, resulting in gaps between the cover plates and the expansion joint, significantly reducing the waterproofing effect and even causing leakage risks. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a passageway for roof expansion joints with varying spans, which solves the aforementioned problems.

[0004] This utility model is implemented as follows:

[0005] A passageway for a roof expansion joint with varying spans includes a grid frame and a folding ladder at both ends. The grid frame includes a grid plate and assembly plates at both ends along its length. A set of uprights is provided at both ends of the top along the length of the assembly plate. Two side uprights are provided on the assembly plate between the two uprights. The folding ladder is hinged to the two side uprights. A telescopic support rod is provided between the folding ladder and the upright on the adjacent side. A lower wing plate is provided at the bottom of the assembly plate. Elastic clamping members are provided on opposite sides of the two lower wing plates.

[0006] In an embodiment of this utility model, the side plate includes a first mounting hole and a second mounting hole opened on its side.

[0007] In an embodiment of this utility model, the folding ladder includes six steps, and each step is hinged to a first connecting rod and a second connecting rod at both ends, with the first connecting rod located below the second connecting rod.

[0008] In an embodiment of this utility model, the telescopic support rod includes an outer rod and an inner rod that are slidably arranged together, and a pin hole is provided on one side of the outer rod and the inner rod. The length of the two rods is adjusted by inserting a pin into the pin hole.

[0009] In an embodiment of this utility model, a hinge seat is provided on the outer side of the upright near the folding ladder, and a hinge shaft is provided on the outer side of the first connecting rod near the upright.

[0010] In an embodiment of this utility model, the end of the outer rod is hinged to the hinge seat, and the end of the inner rod is hinged to the hinge shaft.

[0011] In an embodiment of this utility model, the lower wing plate has movable holes symmetrically arranged along the center on the side near the bottom.

[0012] In an embodiment of this utility model, the elastic clamping member includes a clamping plate, and two guide rods are provided on the side of the clamping plate near the lower wing plate. The two guide rods pass through adjacent movable holes, and a limiting piece is provided at the end of the guide rod. A compression spring is provided on the guide rod between the lower wing plate and the clamping plate.

[0013] In an embodiment of this utility model, the elastic clamping member includes a clamping plate, and two guide rods are provided on the side of the clamping plate near the lower wing plate. The two guide rods pass through adjacent movable holes, and the ends of the guide rods are threaded with limit nuts. A compression spring is provided on the guide rod between the lower wing plate and the clamping plate.

[0014] In an embodiment of this utility model, the clamping plate is an arc-shaped clamping plate.

[0015] The beneficial effects of this utility model are as follows: A passage platform is formed by the grid frame spanning the expansion joint; the folding ladders at both ends, utilizing hinged treads and telescopic support rods, allow for adjustment of the unfolded width according to the height difference of the expansion joint, ensuring a safe distance between the grid plate and the waterproof cover plate below. The elastic clamping components, driven by compression springs, use arc-shaped clamps to elastically clamp the structures on both sides of the expansion joint, achieving initial fixation to prevent displacement while adapting to the deformation characteristics of the expansion joint. The grid frame transfers the passage load to the main structure, avoiding direct stepping on the waterproof cover plate and solving the leakage problem caused by deformation due to stepping on it; the combination of the folding ladder and telescopic support rods can accommodate a certain height difference in the expansion joint; the clamping installation does not require damage to the original structure, and the folding and unfolding method is simple to operate.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] like Figure 1As shown, this utility model provides a passageway for roof expansion joints with varying spans, including a grid frame 10 and a folding ladder 20 at both ends. The grid frame 10 includes a grid plate 11 and an assembly plate 12 at both ends along its length. A set of uprights 13 are provided at both ends of the top of the assembly plate 12 along its length. Two side plates 1201 are provided on the assembly plate 12 between the two uprights 13. The folding ladder 20 is hinged to the two side plates 1201. A telescopic support rod 30 is provided between the folding ladder 20 and the upright 13 on the adjacent side. A lower wing plate 1202 is provided at the bottom of the assembly plate 12. Elastic clamping members 40 are provided on opposite sides of the two lower wing plates 1202. By installing this passageway 23 on the roof expansion joint 50 with varying spans, communication can be facilitated, and the waterproof cover can be protected to ensure that it is not deformed by being stepped on.

[0027] like Figure 2-4 As shown, the side panel 1201 includes a first mounting hole 12011 and a second mounting hole 12012 opened on its side. The folding ladder 20 includes 6 parallel steps 23, and each step 23 has a first connecting rod 21 and a second connecting rod 22 hinged to both ends, with the first connecting rod 21 located below the second connecting rod 22.

[0028] Furthermore, the telescopic support rod 30 includes an outer rod 31 and an inner rod 32 slidably arranged together, and a pin hole is provided on one side of the outer rod 31 and the inner rod 32. The length of the two rods is adjusted by inserting a pin into the pin hole. A hinge seat is provided on the outer side of the upright rod 13 near the folding ladder 20, and a hinge shaft is provided on the outer side of the first connecting rod 21 near the upright rod 13. The end of the outer rod 31 is hinged to the hinge seat, and the end of the inner rod 32 is hinged to the hinge shaft. By combining the telescopic support rod 30 with the folding ladder 20, the deformation joint 50 of different heights can be adapted and adjusted, that is, the bottom width of the two folding ladders 20 decreases as the deformation joint 50 increases in height.

[0029] It should be noted that the adaptation of the folding ladder 20 to the height of the expansion joint 50 is only for the height error caused by the actual construction of expansion joints 50 of the same model (with the same design size). For expansion joints 50 with large size differences, the passage step 23 to be produced needs to be enlarged or reduced proportionally.

[0030] like Figure 2 and Figure 5 As shown, the lower wing plate 1202 has symmetrically arranged movable holes 12021 on the side near the bottom along the center.

[0031] Furthermore, the elastic clamping component 40 includes a clamping plate 41. Two guide rods 42 are provided on the side of the clamping plate 41 near the lower wing plate 1202, and the two guide rods 42 pass through adjacent movable holes 12021 respectively. The ends of the guide rods 42 are also provided with limiting pieces. A compression spring 43 is provided on the guide rods 42 between the lower wing plate 1202 and the clamping plate 41. When the passage step 23 is erected, the two clamping plates 41 elastically clamp both sides of the expansion joint 50. The purpose is to provide a preliminary fixation of the communication step 23 through such an elastic clamping component 40, so as to avoid significant displacement of the step 23 during the climb, such as causing it to tilt significantly or the inner side of the folding ladder 20 on one side to collide with a corner of the expansion joint 50. At the same time, compared with the rigid fixing method, this elastic clamping can adapt to the deformation of the expansion joint 50 and does not cause additional interference to its own deformation characteristics.

[0032] In another embodiment, the elastic clamping member 40 includes a clamping plate 41. Two guide rods 42 are provided on the side of the clamping plate 41 near the lower wing plate 1202. The two guide rods 42 pass through adjacent movable holes 12021 respectively. The ends of the guide rods 42 are threadedly connected to limit nuts 44. A compression spring 43 is provided on the guide rods 42 between the lower wing plate 1202 and the clamping plate 41. The initial position of the two clamping plates 41 can be adjusted by the limit nuts 44 to facilitate subsequent quick clamping.

[0033] As a preferred embodiment, the clamping plate 41 is an arc-shaped clamping plate 41, which reduces the possibility of it getting stuck on the outer wall of the expansion joint 50 during the erection and clamping process.

[0034] Example

[0035] like Figure 6 As shown, in use, the two folding ladders 20 are unfolded to a suitable width, and their length is then fixed by the pins on the telescopic support rod 30. The unfolding standard is that when the two folding ladders 20 are erected on the roof, the distance between the grating plate 11 and the top expansion joint cover plate 60 of the expansion joint 50 is greater than or equal to 10cm. When erecting them on the expansion joint 50, the two clamping plates 41 of the elastic clamping member 40 are used to clamp and fix the outer wall of the expansion joint 50. Through the above structure, the problems of inconvenient passage and reduced waterproofing effect caused by frequent trampling on the waterproof cover plate in the high and low span roof scenario are solved.

[0036] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
