Description

Technical Field

[0001] The utility model relates to the technical field of channel steel connection and installation, in particular to an adjustable steel base suitable for channel steel. Background Art

[0002] Channel steel is a long steel with a grooved cross-section, belonging to carbon structural steel for construction and machinery, and is a profiled steel with a complex cross-section. Its cross-sectional shape is grooved. Channel steel is mainly used in building structures, curtain wall projects, mechanical equipment, vehicle manufacturing, etc.

[0003] The suspension rods of comprehensive pipe galleries usually use channel steel, and a base for connection is required when connecting to the roof. Therefore, in most scenarios of channel steel installation and connection, special channel steel bases are used for installing and fixing channel steel. In order to improve the flexibility of the steel base, some adjustable steel bases have gradually been used. For example, an adjustable-angle channel steel base (Patent No.: CN202223286375.8) includes a bottom plate, a fixed seat and a movable seat. The fixed seat is welded above the bottom plate, and a first docking hole is opened in the middle of the fixed seat. Movable seats are arranged on both sides of the fixed seat, and a second docking hole is opened in the middle of the movable seat. Installation holes are opened on the surface of the bottom plate close to the movable seat; An extension mechanism is jointly arranged between the fixed seat and the movable seat, and the extension mechanism includes a docking groove, a docking block, a spring, a sliding block and a sliding groove. The docking groove is opened on the two side surfaces of the fixed seat. For this adjustable-angle channel steel base, through the movable seat that can extend to both sides, the channel steel base can be docked with channel steel within a certain size range, making the applicable range of the channel steel base wider. Through the rotatable bottom plate that drives the fixed seat and the movable seat to rotate synchronously, the channel steel base has an angle adjustment structure.

[0004] Although the existing adjustable steel base can adapt to channel steel of different sizes by changing the distance between the two movable seats, the two movable seats are movably connected to the fixed seat, so that the weight of the entire channel steel and its load-bearing objects will act on the fixed seat, and the two movable seats cannot play any role in sharing the load; moreover, this connection method that uses spring stretching to support the distance adjustment requires operating the two movable seats simultaneously during installation, which will undoubtedly increase the difficulty of manual installation operation. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the two movable seats of the existing adjustable steel base are movably connected to the fixed seat, so that the weight of the entire channel steel and its load-bearing objects will act on the fixed seat, and the two movable seats cannot play any role in sharing the load; moreover, the connection method that uses spring stretching to support the distance adjustment will increase the difficulty of manual installation operation.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An adjustable steel base applicable to channel steel, comprising a base. The cross-section of the base is in the shape of a runway, and a through-hole for expansion bolts penetrating the base up and down is opened near each of the two arc-shaped sides. The base is installed and fixed by expansion bolts penetrating through the through-hole for expansion bolts. A bearing groove is opened in the middle of the bottom surface of the base. A main fixing plate is arranged below the bearing groove. The top of the main fixing plate is movably arranged in the bearing groove and can move along the width direction of the base. A plurality of through-holes for connecting with the channel steel are opened on the main fixing plate. Sliding grooves are opened on both sides of the bottom surface of the base where the bearing groove is located. Side fixing plates are arranged below both sliding grooves. The top of the side fixing plate is movably arranged below the sliding groove through a movable plate. The movable plate is slidably connected in the sliding groove. A plurality of through grooves for connecting with the channel steel are opened on the side fixing plate.

[0008] Preferably, the longitudinal section of the main fixing plate is in the shape of a right trapezoid, and the surface where the long bottom side is located is the top surface of the main fixing plate, and the surface where the right-angled side is located is the surface in contact with the channel steel for connection. The longitudinal section of the main fixing plate is set in the shape of a right trapezoid, so that the plate thickness of the main fixing plate gradually decreases from top to bottom, reducing the weight of the main fixing plate while ensuring the strength of the main fixing plate.

[0009] Preferably, the longitudinal section of the bearing groove is in the shape of a "convex" character. Concave inner grooves are arranged on both sides of the bearing groove. The depth of the inner groove is the same as half of the depth of the bearing groove. The bearing groove with a longitudinal section in the shape of a "convex" character is provided, and the concave inner grooves on both sides can play a role in limiting the top of the main fixing plate up and down.

[0010] Preferably, a slider is arranged on both sides of the top of the main fixing plate. The slider is slidably connected in the inner groove. The slider is arranged in the inner groove, which can match the inner groove to play a role in limiting the main fixing plate up and down, and at the same time can support the main fixing plate to move in the bearing groove.

[0011] Preferably, a plurality of threaded through-holes are opened above, below and in the direction parallel to the inner groove of the base.

[0012] Preferably, the plurality of threaded through-holes are aligned up and down.

[0013] Preferably, the slider is provided with the same threaded through-holes corresponding to the threaded through-holes on the base. The threaded through-holes on the slider and the base are connected by fastening bolts. Threaded through-holes are opened on the upper and lower parts of the base and on the slider. When the main fixing plate moves to a suitable position, the slider and the base can be tightly connected and fixed by using the fastening bolts, which can improve the stability.

[0014] Preferably, the longitudinal section of the sliding groove is in the shape of a "concave" character.

[0015] Preferably, the longitudinal section of the movable plate is in the shape of a Chinese character 'hui' (a square with a smaller square inside). The movable plate in the shape of 'hui' matches the concave-shaped sliding groove, so that the whole movable plate is clamped in the sliding groove, playing a role of upper and lower limit for the opposite fixed plate, increasing the contact area between the movable plate and the base, reducing the concentrated pressure, and being beneficial to improving the stability.

[0016] Preferably, the through groove is in the shape of a square arranged horizontally, and both sides of the through groove expand outwards to form notch openings. The setting of the horizontally square through groove enables the bolts used when connecting the side fixed plate and the channel steel to adjust their positions within the through groove, and the expanded notch openings can accommodate the nuts at both ends of the bolts.

[0017] The present utility model adopts the above technical solutions, and compared with the prior art, has the following technical effects:

[0018] (1) By providing an independent and non-connected main fixed plate and two side fixed plates, and arranging the main fixed plate and the two side fixed plates in a triangular shape, the main fixed plate and the two side fixed plates can all share the weight from the channel steel, improving the load-bearing capacity of the steel base, enhancing the stability, and being beneficial to ensuring the safety and stability of the channel steel and the hoisting structure system.

[0019] (2) By providing sliders and a convex-shaped bearing groove, and a movable plate in the shape of a 'hui' and a sliding groove in the shape of a concave character, it is possible to move and adjust the positions one by one during installation, simplifying the operation, increasing the contact area between the movable plate and the base, reducing the generation of concentrated pressure, and being beneficial to improving the stability.
