Description

Technical Field

[0001] The utility model relates to the technical field of metal roof system testing, in particular to an adjustable hinge device suitable for metal roof system testing. Background Art

[0002] In recent years, with the continuous development of the economy, the construction of large-span and large-volume airport terminals, stadiums, and exhibition centers has been increasing. As the upper maintenance structure, the role of the metal roof system is extremely important. There is an integrated technology involving the metal roof system and its lower spatial steel truss, that is, the spatial steel truss is assembled on the ground, and the materials of each layer of the metal roof system are assembled on the spatial steel truss on the ground. Then, the steel truss and the metal roof system on it are lifted to the top of the column and the welding work of the remaining rods is completed, so that the spatial steel truss and the metal roof system on it are smoothly dropped to the top of the column. This construction method simplifies the process and greatly shortens the construction period. However, there is a problem, that is, the metal roof system will deform as the spatial steel truss is lifted together with the spatial steel truss. Whether this deformation will damage the metal roof system and make it lose its windproof and waterproof capabilities requires a metal roof system test to determine.

[0003] The metal roof system is a complex whole with the characteristics of large area and large span. When conducting tests, a plate is usually selected at the maximum deformation position of the finite element simulation. The selected plate will be constrained by the surrounding plates. In order to consider this constraint, when testing the metal roof system, an articulated device is required to constrain the specimen on all sides on the loading platform to meet the actual situation and achieve more ideal test conditions.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] Example 1

[0031] See also Figure 1-12 : An adjustable hinged device suitable for testing metal roofing systems, comprising a base 1 mounted on a loading platform, a U-shaped plate 2 rotatably connected to the base 1, a square box 3 adjustably mounted up and down on the inner side of the U-shaped plate 2, and the upper part of the square box 3 is used to support the metal roofing system.

[0032] The adjustable hinge device of this embodiment can be connected between the four sides of the metal roof system and the loading platform. In the test of the metal roof system, the lower purlin is usually used as the load-bearing skeleton, and the purlin is installed on the loading platform through the purlin bracket. This results in a clearance between each layer of the metal roof system above the purlin and the loading platform. The height of this clearance varies with the height of the purlin bracket and the size of the purlin. For this reason, a square box is adjustably installed on the inner side of the U-shaped plate up and down, which realizes the vertical height adjustment to meet the different clearance heights between the metal roof system and the loading platform, so that the four sides of the metal roof system and the loading platform can be smoothly hinged.

[0033] In a specific example, ladder columns 20 are symmetrically installed at both ends of the inner side of the U-shaped plate 2, and the ladder columns 20 are provided with T-shaped holes 200 along the height direction. The outer ends of the T-shaped holes 200 are spaced apart with horizontal slots 201. Both ends of the outer side of the square box 3 are provided with T-shaped columns 30 corresponding to the T-shaped holes 200, and both ends of the bottom of the square box 3 are provided with horizontal clamping plates 31 corresponding to the slots 201 for limiting and fixing the square box 3.

[0034] When the T-shaped column of the square box is inserted into the T-shaped hole in the ladder column, the square box can be moved up and down in the U-shaped plate. When it is adjusted to the appropriate height, the horizontal clamping plates at both ends of the bottom of the square box are engaged with the slots to limit and fix the square box.

[0035] In a specific example, a waist-shaped hole 310 is opened on the transverse clamping plate 31 , and the bottom of the square box 3 is fixed to the transverse clamping plate 31 by bolts engaging with the waist-shaped hole 310 .

[0036] When the bottom of the square box is fixed with a horizontal clamping plate by bolts, the horizontal clamping plate is provided with waist-shaped holes, so that the horizontal clamping plate can move horizontally left and right relative to the bottom of the square box without affecting the fitting installation between the square box and the U-shaped plate; when the horizontal clamping plate is inserted into the slot of the ladder column and fixed, the square box is fixed and cannot move up and down. When the horizontal clamping plate is pulled out of the slot of the ladder column, the square box can be adjusted and moved up and down along the ladder column.

[0037] In a specific example, the base 1 includes a scale plate 10 and a U-shaped support plate 11, and the scale plate 10 is fixed to both ends of the inner side of the U-shaped support plate 11 by bolts. The scale plate 10 is provided with a through hole, and the through hole is surrounded by a scale dial 100 with a scale of 15° per grid. A rotating wheel 101 is installed on the through hole; the rotating wheel 101 includes an inner wheel 1010 and an outer wheel 1011 that are threadedly connected to each other, and the inner wheel 1010 is provided with a corner hole 10100; the U-shaped plate 2 is provided with an embedded platform 21 corresponding to the corner hole 10100, and the outer wheel 1011 is provided with a scale line 10110.

[0038] When the U-shaped plate is installed on the scale plate through the rotating wheel, the embedded platform on the U-shaped plate is embedded in the corner hole in the inner wheel, and their surfaces are matched. The rotation of the U-shaped plate will drive the rotating wheel to rotate. There is a scale line on the outer wheel. When the rotating wheel rotates, the scale line is aligned with the different scales of the dial, so that the rotation reading can be read. Each grid of the dial is set to 15°, which is convenient for observing the loading speed during the test and controlling the loaded metal roof system test accordingly through other equipment.

[0039] In a specific example, a retractable lever system 4 for fixed installation with the loading platform is installed on the U-shaped support plate 11 .

[0040] This embodiment uses a telescopic arm system to enable the U-shaped support plate to be firmly fixed on the loading platform, thereby avoiding welding the device to the loading platform and making the articulated device easy to install and move on the loading platform.

[0041] In a specific example, the telescopic arm system 4 includes a fixed screw 40 installed at the bottom center of the U-shaped pallet 11, a rotating collar 41 is installed on the fixed screw 40, and an expansion nut 42 for limiting is provided between the rotating collar 41 and the fixed screw 40, and slides 43 are installed obliquely symmetrically in the long oval holes on both sides of the rotating collar 41, and a movable bolt 44 corresponding to the long oval holes on both sides of the rotating collar 41 is provided on the top of one end of the slide 43, and a plate hook 45 for combining with the loading platform is installed on the side of the other end through a bolt; guide wheels 46 are provided on both sides of the slide 43, and the guide wheels 46 are installed on the U-shaped pallet 11, and the guide wheels 46 distributed on both sides of the two slides 43 are obliquely symmetrical with the fixed screw 40 at the bottom center of the U-shaped pallet 11.

[0042] The retractable lever arm system of this embodiment is put on the fixed screw by rotating the collar, and the rotating collar exerts force on it through the expansion nut, so that it is embedded in the groove around the fixed screw; the rotating collar can rotate around the fixed screw, and when the rotating collar rotates, the slide plate is moved inward and outward by the movable bolt. During the process of moving inward and outward, the slide plate is constrained by the guide wheel, so that it can only move inward and outward in a straight line. During the process of moving inward and outward, the slide plate will drive the plate hook to move inward and outward, so that the loading platform can be hooked.

[0043] In a specific example, an oblong hole 450 is provided on the plate hook 45 , and the plate hook 45 is fixed to the end side surface of the slide plate 43 through the oblong hole 450 in conjunction with a bolt.

[0044] The plate hook of this embodiment is fixed to the outside of the slide plate by fixing bolts and oblong holes, so that the plate hook can move up and down along the outside of the slide plate, thereby adapting to loading platforms of different thicknesses and clamping the loading platform.

[0045] In a specific example, the fixed screw 40 , the guide wheel 46 and the U-shaped support plate 11 are welded together, and the movable bolt 44 and the slide plate 43 are welded together.

[0046] This embodiment can improve the installation stability of the fixed screw, guide wheel and movable bolt through welding; it should be noted that the guide wheel and movable bolt of this embodiment can rotate on their own, and the welding points with the U-shaped support plate and the slide plate are their respective rotation axis positions.

[0047] In summary, the vertical height of this embodiment is adjustable, so that it can be adjusted to the size of a "box", achieving the characteristics of being easy to carry, easy to transport, and space-saving. At the same time, the vertical adjustability also meets the different clearance height requirements between the metal roof system and the loading platform;

[0048] The connections between the various components of this embodiment are all detachable, achieving the characteristics of easy installation and easy adjustment;

[0049] The upper part of this embodiment can drive the rotating wheel to rotate around the hole of the scale plate. The rotating wheel has a scale line, and the rotation degree can be directly read, which is convenient for observing and controlling the loading speed during the test;

[0050] The U-shaped support plate of this embodiment is equipped with a retractable arm system, which can control the extension and retraction of the plate hook so that it is firmly fixed on the loading platform, avoiding the defect that the conventional hinged device needs to be welded to the loading platform. This structural form ensures the flatness of the loading platform surface and the mobility of the hinged device.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
