Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and specifically to a roof panel joint limiting and adjusting device and its construction method. Background Technology
[0002] Prefabricated steel-light aggregate concrete composite roof panels have the advantages of light weight and fast construction, and are widely used in building engineering; however, during the installation process, it is difficult to precisely control the width of the gap between adjacent roof panels.
[0003] Currently, the spacing between roof panels is mostly adjusted based on experience using tools such as pry bars and sledgehammers. This results in problems such as uneven panel width, low installation efficiency, and quality that depends on the skill level of the workers. Panels that are too narrow will cause friction damage between the panels, while panels that are too wide will increase the cost of grouting materials and bring the risk of leakage. Furthermore, uneven panel gaps will affect the stress on the connectors and endanger the overall stability.
[0004] Therefore, there is an urgent need for a specialized device and method that can achieve precise and efficient adjustment of the board gaps. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a roof panel joint limit adjustment device and its construction method, thereby solving the problems of low quality and efficiency in adjusting the joint spacing of roof panels using conventional tools in the prior art.
[0006] To achieve the above objectives, the present invention provides a roof panel joint limiting adjustment device for adjusting the joint spacing between unfixed and fixed roof panels; the limiting adjustment device includes: The first and second rods are rotatably connected at their lower parts by a hinge point, so that the bottom ends of the first and second rods can open or close to each other. An adjustable limiting mechanism is connected between the first and second rods, located above the hinge point; By adjusting the adjustable limiting mechanism, the maximum distance between the bottom ends of the first and second rods in the opening direction can be preset and limited, and this maximum distance corresponds to the target plate gap spacing.
[0007] By adopting this technical solution, a device specifically designed for adjusting panel joints is constructed through the combination of a first rod, a second rod, and an adjustable limiting mechanism. The adjustable limiting mechanism enables preset functions, allowing the maximum distance to be pre-set according to design requirements before operation. During construction, simply opening the bottom ends of the first and second rods relative to each other until they are blocked by the adjustable limiting mechanism transforms control from relying on worker experience and feel into control guaranteed by a mechanical structure. This fundamentally eliminates human error, ensuring the consistency and accuracy of all panel joint widths, thereby guaranteeing the installation quality of the roof panels and avoiding frictional damage, stress concentration, waste of grout material, and leakage risks caused by uneven panel joints.
[0008] Furthermore, the adjustable limiting mechanism is a foldable linkage mechanism; When the adjustable limiting mechanism folds toward the hinge point, it drives the bottom ends of the first and second rods to close together. When the adjustable limiting mechanism is extended to a preset state, it restricts the further opening of the bottom ends of the first and second rods.
[0009] By adopting this technical solution, the folding and unfolding of the linkage mechanism is used to drive the closing and opening of the bottom ends of the first and second links, resulting in high force transmission efficiency and reliable operation.
[0010] Furthermore, the adjustable limiting mechanism includes a first sub-rod and a second sub-rod; The first sub-rod and the second sub-rod are hinged to each other via a folding hinge. The end of the first sub-rod away from the folding hinge axis is detachably connected to the first rod, and the end of the second sub-rod away from the folding hinge axis is detachably connected to the second rod.
[0011] By adopting this technical solution, which uses a structure with two sub-rods hinged together and connected to the main rod via a detachable connection, the adjustable limiting mechanism itself becomes an independent and adjustable functional module. This structure is simple, easy to manufacture and assemble, and provides a physical basis for achieving precise limiting by changing the position of the connection point. It is a key specific implementation method for realizing the adjustable function.
[0012] Furthermore, both the first and second sub-rods are provided with evenly distributed limiting holes, and the limiting holes are equipped with matching fasteners; By selecting different limiting holes and matching fasteners, the connection points of the first sub-rod and the second sub-rod with the first rod and the second rod respectively can be changed. By changing the position of the connection point, the maximum unfolding angle of the top ends of the first and second rods is limited, thereby presetting the maximum distance between the bottom ends of the first and second rods.
[0013] By adopting this technical solution, which uses limiting holes and fasteners in combination, the effective length of the adjustable limiting mechanism can be changed in a step-by-step and precise manner by selecting different hole positions, thereby accurately controlling the opening distance of the bottom ends of the first and second rods. Once locked by the fasteners, the limiting value will not drift during the jacking of the roof panel, ensuring the uniqueness and accuracy of the jacking result and strong anti-interference ability. This adjustment method is very intuitive for construction personnel, requiring no complicated tools or advanced skills, and is easy to implement quickly on site.
[0014] Furthermore, the adjustable limiting mechanism is provided with a scale, which is used to indicate the size related to the maximum distance.
[0015] By adopting this technical solution, the scale provides intuitive visual indication, allowing operators to quickly and accurately find the adjustment position corresponding to the target board gap without the need for additional measuring tools, greatly improving the efficiency of the preset steps.
[0016] This invention also provides a construction method for a roof panel joint limiting and adjusting device, used to adjust the joint spacing between unfixed and fixed roof panels; the construction method includes the following steps: Preset steps: Adjust the adjustable limiting mechanism according to the target board gap width to preset the maximum distance between the bottom ends of the first rod and the second rod; Closing step: The adjustable limiting mechanism is retracted, causing the bottom ends of the first and second rods to close together; Insertion step: Insert the closed bottom end into the gap between the fixed first roof panel and the second roof panel to be adjusted; Pushing step: Apply external force to open the bottom ends of the first and second rods until they are limited by the adjustable limiting mechanism, thereby pushing the second roof panel to the target position and forming a panel joint with precise width.
[0017] By adopting this technical solution, the mechanical advantages of the device are transformed into a set of standardized and procedural operating procedures, ensuring that the advantages of the device are fully utilized.
[0018] Compared with the prior art, the present invention has the following advantages: 1. Precise control of the gap width is achieved through preset mechanical limiters, eliminating human error and ensuring installation quality.
[0019] 2. The device is foldable and has a smooth operation process, which solves the construction problem in confined spaces and protects the roof panels from scratches.
[0020] 3. It has a simple structure, low manufacturing cost, convenient adjustment, and can adapt to different requirements for board gap width, making it highly versatile.
[0021] 4. Standardized construction methods reduce reliance on operator experience and significantly improve construction efficiency and first-pass yield. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0025] Please see the appendix Figure 1-3 The present invention provides a roof panel gap limiting adjustment device for adjusting the gap between an unfixed roof panel and a fixed roof panel; the limiting adjustment device includes a first rod 1, a second rod 2, a hinge shaft 3 and a limiting folding rod; The first member 1 is integrally formed by the first force-applying rod 11, the first force-transmitting rod 12 and the first load-bearing plate 13; the second member 2 is integrally formed by the second force-applying rod 21, the second force-transmitting rod 22 and the second load-bearing plate 23; the first load-bearing plate 13 and the second load-bearing plate 23 constitute the bottom end of the device, which is used to directly contact the side of the roof panel.
[0026] The first lever 1 and the second lever 2 are hinged at the lower middle part by a hinge shaft 3, and the two are connected at a 74° angle to form a force-saving lever mechanism; wherein, the length of the first force-applying rod 11 and the second force-applying rod 21 from the end to the hinge shaft is 1500mm; the diameter of the hinge shaft is 40mm; in order to further reduce the difficulty of manual control of the first lever 1 and the first lever 2, a handle 5 is also connected to the top of both.
[0027] The first force transmission rod 12 and the second force transmission rod 22 are in the shape of right-angled triangular curved arms, with a front arm length of 128mm and a rear arm length of 96mm; the first support plate 13 and the second support plate 23 are 40mm long, 30mm wide and 5mm thick.
[0028] The limiting folding rod serves as an adjustable limiting mechanism 4, comprising a first sub-rod 41 and a second sub-rod 42, which are hinged together by a folding hinge pin 43.
[0029] The first force-applying rod 11 and the second force-applying rod 21 are respectively provided with a threaded round hole at their center positions; a hexagonal bolt is used as a fastener 45, and the distal end of the first sub-rod 41 is detachably connected to the threaded round hole of the first force-applying rod 11 through the hexagonal bolt; the distal end of the second sub-rod 42 is detachably connected to the threaded round hole of the second force-applying rod 21 through another hexagonal bolt.
[0030] Multiple sets of evenly distributed limiting holes 44 are provided on the first sub-rod 41 and the second sub-rod 42. By selecting different limiting holes 44 and anchoring them with hexagonal bolts, the connection points of the first sub-rod 41 and the second sub-rod 42 with the first force-applying rod 11 and the second force-applying rod 21 can be changed. This change limits the maximum unfolding angle of the top of the first rod 1 and the second rod 2, thereby pre-setting the maximum distance between the first support plate 13 and the second support plate 23.
[0031] The first sub-rod 41 and the second sub-rod 42 are provided with double scales above the first limiting hole 44, namely the actual size scale and the adjusting size scale; the actual size scale range is 0~120mm, and the adjusting size scale range is 0~50mm, and a limiting hole 44 is provided every 30mm along the actual size scale direction; the adjusting width W indicated by the adjusting size scale and the actual width L indicated by the actual size scale satisfy the following relationship: W=(1 / 3)*L-10mm; this relationship is calculated based on the lever ratio of the device and the thickness compensation of the load-bearing plate itself; For example, when a 30mm design gap is required, according to the above relationship, the limiting hole 44 with a gap adjustment scale of 30mm and an actual size scale of 60mm should be selected for connection.
[0032] The construction method of this embodiment includes the following steps: The first roof panel was accurately installed onto the designated beam and then welded in place. Hoist the second roof panel to a position close to the first roof panel; According to the design of the plate joint width, based on the relationship W=(1 / 3)*L-10mm, select the corresponding limiting holes 44 on the first sub-rod 41 and the second sub-rod 42, and use hexagonal bolts to anchor the first force-applying rod 11 and the second force-applying rod 21 to the first sub-rod 41 and the second sub-rod 42. Bring the first rod 1 and the second rod 2 inward so that the limiting folding rod folds toward the hinge axis. At this time, the first bearing plate 13 and the second bearing plate 23 are in the closed state. Insert the first load-bearing plate 13 and the second load-bearing plate 23, which are in the closed state, into the gap between the fixed first roof panel and the second roof panel to be adjusted, and press the first load-bearing plate 13 against the side of the first roof panel. The construction worker stands on the first roof panel and pushes the handle 5 on the second rod 2 outward. The thrust is transmitted to the second roof panel through the second load-bearing plate 23. The limiting folding rod unfolds until it is mechanically limited. At this time, the second roof panel is pushed to the position of the preset panel joint width. Secure the second roof panel; Repeat the above steps to complete the installation of the roof panels.
[0033] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
