Description

Technical Field

[0001] This utility model belongs to the field of steel structure, specifically a structure for H-shaped steel sloping roof trusses. Background Technology

[0002] In modern industrial plant and building construction, the installation of electromechanical pipelines and the installation of decorative ceilings are essential steps, and these operations often require various support devices to ensure the stability and safety of the structure. In current technological fields, industrial plant roof trusses often use steel profiles for slope creation, which places high demands on structural protection and installation precision during the installation of electromechanical pipelines and decorative ceilings.

[0003] During the installation of electromechanical pipelines and the decoration and renovation of ceilings, drilling and welding on the steel structure are not permitted to avoid damage. Therefore, when using threaded rods, clamps are typically used to fix the rods to the structural steel. This fixing method is relatively simple to operate, requires no additional processing of the steel structure, and to a certain extent meets the requirement of not damaging the steel structure. However, for H-shaped steel structures with slopes, the use of clamps has significant shortcomings. The clamp fixing method cannot guarantee that the rod is perpendicular to the load-bearing surface. When a load is applied to the lower part of the rod, it will bend and deform. This not only affects the mechanical properties of the rod itself, preventing it from fully utilizing its load-bearing capacity, but may also lead to deviations in the installation positions of ceiling joists, pipes, cable trays, light fixtures, and secondary steel structure conversion supports, affecting the quality and safety of the entire installation project. Furthermore, the existing fixing method also has difficulties in adjusting the height and flatness of the rods, making it difficult to meet the installation accuracy requirements in actual construction, resulting in low construction efficiency. Utility Model Content

[0004] To address the above issues, this utility model proposes a structure for H-shaped steel sloping roof trusses. Through the cooperation of components such as Y-shaped brackets and C-shaped steel angle brackets, the suspension rods are made perpendicular to the load-bearing surface. It has the advantages of convenient installation, adjustable height and flatness, simple structure, and easy mass production.

[0005] To achieve the above objectives, the present invention specifically employs the following technical means:

[0006] A structure for H-shaped steel sloping roof trusses, comprising:

[0007] Y-type bracket, external hexagonal bolt through threaded rod, angle bracket C-shaped steel, square gasket, through threaded rod, square adjuster, T-Bar keel, cross joint, H-steel structure and through threaded bolt;

[0008] The C-shaped angle bracket has an opening in the middle of one side. The external hexagonal bolt passes through the threaded rod through the opening and connects to the openings on both sides of the Y-shaped bracket. A gap is reserved between the Y-shaped bracket and the C-shaped angle bracket, and the bolt is fixed by adjusting the nut of the threaded rod.

[0009] The through-thread screw is connected to the square adjuster by a through-thread bolt, passes through the opening at the bottom of the Y-shaped card seat, and is fixed by a square washer;

[0010] The T-Bar keels are connected to each other via cross joints, and the square adjuster is fixed to the T-Bar keel via threaded bolts.

[0011] Furthermore, the C-shaped angle bracket and the H-shaped steel structure are clamped and fixed by external hexagonal bolts through threaded rods, and the H-shaped steel structure is a sloping roof truss structure.

[0012] Furthermore, the length of the threaded screw is adjusted by the threaded bolt to adjust the flatness of the lower keel.

[0013] This utility model has the following beneficial technical effects:

[0014] When installing the Y-type mounting bracket and the C-shaped steel angle bracket, a gap is left, and the nut of the threaded rod is finely adjusted using an external hexagonal bolt. This design allows the Y-type mounting bracket to rotate freely around the external hexagonal bolt relative to the threaded rod (as the central axis), thus adapting to the tilt angle of the H-shaped steel structure and ensuring the threaded rod remains perpendicular to the ground. Furthermore, the threaded rod naturally remains vertical due to gravity in its free state, and its length can be customized according to the measured height. Combined with the bidirectional adjustment function of the square adjuster, the threaded rod can precisely control the verticality of the suspension rod, preventing tilting caused by the slope of the H-shaped steel structure.

[0015] The effective length of the threaded rod in this structure can be changed by rotation. During installation, the threaded rod is cut or adjusted according to the measured height to precisely control the vertical height of the hanger. Each hanger can be adjusted independently, and by uniformly adjusting the length of the threaded rods of multiple hangers, the overall height of the lower keel can be made consistent, thus ensuring flatness. Simultaneously, the square adjuster is connected to the threaded rod via threaded bolts, providing fine-tuning functions in the lateral or longitudinal direction. When fixing the T-Bar keel, the square adjuster allows for small adjustments to the horizontal position of the keel, further eliminating installation errors and ensuring alignment between keels.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. It should also be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clearly assist in illustrating the embodiments of the present invention.

[0021] Please see Figures 1-3 This utility model provides a structure for maintaining the verticality of the hanger rod of an H-shaped steel roof truss to the load-bearing surface. It mainly includes a Y-shaped bracket 1, an external hexagonal bolt through-threaded rod 2, angle bracket C-shaped steel 3, a square washer 4, a through-threaded rod 5, a square adjuster 6, a T-Bar keel 7, a cross joint 8, an H-shaped steel structure 9, and through-threaded bolts 10. The Y-shaped bracket 1 is connected to the angle bracket C-shaped steel 3 on both sides through the external hexagonal bolt through-threaded rod 2. One side of the angle bracket C-shaped steel 3 has a central hole to accommodate the insertion of the external hexagonal bolt through-threaded rod 2. The through-threaded rod 5 is inserted into the central hole at the bottom of the Y-shaped bracket 1 and fixed by the square washer 4 and the through-threaded bolt 10, forming an adjustable vertical hanger rod structure.

[0022] The flange plate of the H-shaped steel structure 9 is clamped and fixed by angle bracket C-shaped steel 3. A 1-2mm gap is reserved between the Y-shaped bracket 1 and the angle bracket C-shaped steel 3. The gap is adjusted by using an external hexagonal bolt to connect the nut of the threaded rod 2. The threaded rod 5 is always perpendicular to the ground in its free state, and its lower end is connected to the T-Bar keel 7 through a square adjuster 6. The square adjuster 6 has threaded bolts 10 on both sides to fix the relative position of the threaded rod 5 and the T-Bar keel 7, and at the same time allows the keel height to be adjusted by rotating the threaded rod 5.

[0023] The T-Bar keel 7 achieves multi-directional connection via a cross joint 8, and the bottom of the square adjuster 6 is fixed to the T-Bar keel 7 with bolts. This device, through the pre-reserved adjustment margin of the Y-type bracket 1 and the vertical characteristic of the threaded screw 5, ensures that the hanger is always perpendicular to the load-bearing surface. Combined with the fine-tuning function of the square adjuster 6, precise control of the keel's flatness can be quickly achieved. The entire structure requires no welding or drilling, effectively protecting the original structural integrity of the H-steel structure 9.

[0024] The device used to keep the hangers perpendicular to the load-bearing surface of the H-shaped steel sloping roof truss includes the following assembly steps:

[0025] Before construction, Y-type brackets 1 and external hexagonal bolt threaded rods 2 of appropriate specifications were precisely customized according to the width of the H-beam flange plates. This ensured the fitting accuracy between the components and guaranteed the subsequent installation and use effectiveness of the device.

[0026] Install the customized Y-type bracket 1, the hexagonal bolt through-thread rod 2, and the angle bracket C-shaped steel 3 onto the corresponding H-steel structure 9. During installation, ensure that the hexagonal bolt through-thread rod 2 can be smoothly inserted into the center hole on one side of the angle bracket C-shaped steel 3; simultaneously, ensure that the hexagonal bolt through-thread rod 2 and the threaded rod 5 can be smoothly inserted into the center holes on both sides and the bottom of the Y-type bracket 1. Furthermore, leave a 1-2mm gap between the Y-type bracket 1 and the angle bracket C-shaped steel 3 during installation; this gap can be adjusted using the nut on the hexagonal bolt through-thread rod 2.

[0027] Use measuring tools to accurately measure the vertical distance from the 1. Y-type bracket to the top of the 7. T-Bar keel. Based on the measured height, cut the threaded rod 5 to ensure a precise fit and facilitate subsequent installation.

[0028] Assemble the threaded screw 5 and the square adjuster 6 using threaded bolts 10, ensuring a secure connection during assembly. Then, insert the assembled component into the Y-shaped bracket 1 and connect it to the threaded bolts 10 using square washers 4, ensuring a stable connection.

[0029] Assemble the T-Bar keel 7 and cross joint 8 on the ground, and use a lift to transport the assembled keel components to the designated height. Once the designated height is reached, fix the square adjuster 6 to the T-Bar keel 7 with bolts to complete the installation of the entire device. During the fixing process, ensure that all connections are tightly fitted without any looseness to guarantee the overall performance and stability of the device.

[0030] After installation, the flatness of the lower T-Bar keel 7 can be adjusted by adjusting the threaded screw 5 according to actual needs, ensuring that the installation effect meets the project requirements.
