Abstract
Description
Technical Field
[0001] This utility model relates to the field of profiled steel sheet roofing construction technology, specifically to a heavy-duty profiled steel sheet roofing sliding support. Background Technology
[0002] Corrugated steel sheet roofing (also known as thin steel sheet or corrugated thin steel sheet roofing) consists of corrugated thin steel sheets, supports, steel purlins, and connecting bolts. This type of roofing offers advantages such as flexible building layout, light weight, high compressive strength, rapid construction, and economy. The supports, as crucial components connecting the roof panels and structural purlins, determine the quality of the roof installation.
[0003] Support structures for profiled steel roofs include fixed and sliding supports. Fixed supports cannot accommodate thermal expansion and contraction. Metal building materials expand and contract when subjected to large temperature differences, which can cause the fixed supports to compress or crack the roof panels, affecting structural stability. Therefore, fixed supports are mainly used in temporary projects with low waterproofing requirements and small roof sizes. Sliding supports for metal roofs effectively solve the problem of thermal expansion and contraction caused by temperature changes, allowing the metal roof panels to expand and contract freely with temperature variations, avoiding deformation or damage to the panels due to temperature stress.
[0004] Existing profiled steel sheet sliding supports include L-shaped and inverted trapezoidal types. L-shaped sliding supports are single-piece, upright iron sheets, which have limited vertical load-bearing capacity and poor lateral stability; individual components are essentially unable to resist lateral forces, and they are generally used for lightweight roofs in ordinary climates. Inverted trapezoidal sliding supports have an inverted trapezoidal structure, which improves both vertical and horizontal load-bearing capacity and can adapt to certain harsh climates. However, the trapezoidal shape itself is not a stable structure, and this type of support is prone to deformation under stress. Accumulated deformation can affect the tightness of the roof panel installation, leading to leaks. Furthermore, the sliding mechanism of this type of support relies on clamps riding on guide rails; wear and upper loads can cause the guide rails to extend into the clamps, thus reducing sliding performance.
[0005] Therefore, there is an urgent need for a profiled steel sheet roof sliding support with high vertical bearing capacity, good lateral stability, resistance to deformation, and good sliding performance. Summary of the Invention
[0006] The purpose of this utility model is to provide a heavy-duty profiled steel sheet roof sliding support to at least solve the problems of limited vertical bearing capacity, poor lateral stability, easy deformation under stress, and poor sliding performance of the existing technology.

[0034] Example 1:
[0035] like Figure 1 As shown in the figure, this embodiment provides a heavy-duty profiled steel sheet roof sliding support, including a support 1 and a sliding member 2.
[0036] like Figure 2As shown, the support 1 is a vertical double-layer structure, which effectively improves the vertical bearing capacity. The front and back of the support 1 are both inverted trapezoidal, and the side is inverted Ώ-shaped. The support 1 is fixed to the roof structure 15. The top center of the support 1 has a first slotted groove 7, the front has a second slotted groove 8, and the back has a third slotted groove 19.
[0037] The second slotted slide 8 and the third slotted slide 19 are symmetrically arranged, and the lengths of the second slotted slide 8 and the third slotted slide 19 are longer than the first slotted slide 7, which facilitates the sliding of the sliding member 2.
[0038] The support 1 includes a first side plate 20 and a second side plate 21. The first side plate 20 and the second side plate 21 are arranged vertically and parallel to each other. The left and right ends of the first side plate 20 and the second side plate 21 are respectively straight segments and arc segments. The four arc segments have the same height and curvature. The arc segments at the left and right ends of the first side plate 20 and the second side plate 21 are symmetrically arranged along the vertical center lines of the first side plate 20 and the second side plate 21, and the curvature is directed towards the vertical center lines of the first side plate 20 and the second side plate 21.
[0039] The bottom of the first side plate 20 and the second side plate 21 are horizontally welded to the first support foot 4 and the second support foot 5, respectively. The first support foot 4 and the second support foot 5 are horizontally symmetrically arranged along the vertical center line between the first side plate 20 and the second side plate 21. The first support foot 4 and the second support foot 5 are both cuboids. The cross sections of the first side plate 20, the first support foot 4, the second side plate 21, and the second support foot 5 are symmetrical L-shaped. The first support foot 4 and the second support foot 5 are fixed to the roof structure component 15 by two symmetrical self-tapping screws 3, thereby fixing the support 1 to the roof structure component 15.
[0040] The top left and right sides of the second side plate 21 are respectively welded with a first support plate 9 and a second support plate 10 for stabilizing the roof profiled steel sheet 16. The first support plate 9 and the second support plate 10 are the same size and are both cuboids. The first support plate 9 and the second support plate 10 extend forward along the top of the second side plate 21. A connecting plate connects the first support plate 9 and the second support plate 10.
[0041] The left and right ends of the connecting plate are integrally formed with the first support plate 9 and the second support plate 10, respectively. The rear end of the connecting plate is connected to the top of the second support plate 21, and the front end of the connecting plate is connected to the top of the first support plate 20. The width of the connecting plate is smaller than the width of the first support plate 9 and the second support plate 10. The first slotted slide 7 is opened on the connecting plate, and the length of the first slotted slide 7 is smaller than the length of the connecting plate.
[0042] Three stiffening ribs 6 are welded at equal intervals on the first side plate 20 and the first support foot 4, respectively. The three stiffening ribs 6 on the first side plate 20 and the first support foot 4 are connected to each other and have an L-shaped side. Three stiffening ribs 6 are welded at equal intervals on the second side plate 21 and the second support foot 5, respectively. The three stiffening ribs 6 on the second side plate 21 and the second support foot 5 are connected to each other and have an L-shaped side. The stiffening ribs 6 make the first side plate 20 and the second side plate 21 less prone to deformation under stress.
[0043] Furthermore, the sliding member 2 has a vertical double-layer structure, which effectively improves the vertical bearing capacity. The bottom of the sliding member 2 is embedded in the support 1 through the first slotted sliding groove 7, and the two ends of the bottom are respectively set in the second slotted sliding groove 8 and the third slotted sliding groove 19 from the inside to the outside. The two ends of the bottom are mechanically squeezed and locked on the support 1. The sliding member 2 is inserted into the support 1, and the support 1 provides good lateral stability. The slotted sliding groove ensures the smoothness and reliability of the sliding member 2 and improves the sliding performance of the roof profiled steel sheet 16 under heavy load due to thermal expansion and contraction.
[0044] like Figure 3 As shown, the sliding member 2 is I-shaped, including a first side plate 22 and a second side plate 23. The first side plate 22 and the second side plate 23 are vertically fitted together. The first side plate 22 and the second side plate 23 of the sliding member 2 are clamped by the support 1. The top of the second side plate 23 is bent and extended to wrap around the top of the first side plate 22, forming a coiled joint 13. The bottom of the first side plate 22 and the second side plate 23 forms sliding feet 11. The sliding feet 11 are symmetrically located on both sides of the first side plate 22 and the second side plate 23, and the sliding feet 11 are respectively located in the second slot. In the sliding groove 8 and the third slotted sliding groove 19, the sliding function between the sliding member 2 and the support 1 is realized. The middle of the left and right ends of the first side plate 22 and the second side plate 23 are respectively arc-shaped 12, so that the sliding member 2 has a space to slide freely in the first slotted sliding groove 8. The four arc-shaped 12 are the same size and are symmetrically arranged along the vertical center line of the first side plate 22 and the second side plate 23, respectively. The curvature is all towards the vertical center line of the first side plate 22 and the second side plate 23. In other embodiments, the arc-shaped 12 can also be set as a broken line shape.
[0045] Furthermore, such as Figure 4 and Figure 5 As shown, the roof profiled steel sheet 16 and the roll joint 13 are mechanically rolled and interlocked to form a standing seam.
[0046] The profiled steel sheet 16 of the roof is clamped with fasteners 17 to form a bracket on the roof panel for installing roof equipment 18.
[0047] The sliding member 2 is inserted into the first slot 7 at the top of the support 1. The sliding foot 11 of the sliding member 2 sits in the second slot 8 and the third slot 19 of the support 1 and is locked to the support 1 by mechanical compression. The support 1 is fixed to the roof structure 15. The sliding member 2 of the sliding bracket 14 follows the thermal expansion and contraction of the upper roof profiled steel sheet 16 and slides freely along the three slots.
[0048] Example 2:
[0049] In this embodiment, the first side plate 22 and the second side plate 23 of the slider 2 are welded to form an integral structure of the slider 2, making the slider 2 more stable during sliding.
[0050] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
