Description

Technical Field

[0001] This utility model belongs to the field of support frame technology, specifically relating to an adjustable height steel structure support frame. Background Technology

[0002] In the field of architectural engineering, from towering skyscrapers to uniquely designed commercial complexes, steel structures, with their outstanding strength, can easily withstand enormous vertical and horizontal loads, ensuring the stability of buildings in various complex environments. Simultaneously, their lightweight nature greatly reduces the burden on the foundation structure, lowers foundation construction costs, and allows for rapid construction, effectively shortening the project cycle and bringing buildings to market faster. In bridge construction, steel structures, with their excellent spanning capabilities, facilitate the construction of long-span bridges, enabling the smooth connection of rivers, lakes, and seas. In the construction of various industrial plants, the flexible design space of steel structures can meet the specific spatial layout requirements of different production processes.

[0003] However, significant problems have arisen in the construction and subsequent use of these steel structures, particularly in the steel structure support frames, which serve as crucial supporting components. Traditional steel structure support frames are mostly designed with a fixed height, a design that has revealed numerous drawbacks in practical applications. In construction projects, the requirements for steel structure support height vary greatly depending on the floor height and functional area. For example, when constructing high-rise office buildings, the ground floor lobby often requires a high headroom, while the standard office floors have relatively fixed and lower heights. When using fixed-height steel structure support frames, construction workers must undertake complex modifications to meet the lobby's height requirements. This may involve a series of processes such as cutting and welding, requiring not only professional construction skills but also strict quality control at each modification stage; otherwise, the overall strength and stability of the support frame will be affected. This process is extremely time-consuming; modifying a single support frame can take hours or even days, severely slowing down the construction progress. Without modification, the only option is to purchase and replace the support frame with one suitable for the lobby height, which undoubtedly increases material procurement costs as well as additional expenses for transportation and installation. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-height steel structure support frame, aiming to solve the problem that most traditional steel structure support frames are designed with a fixed height, which exposes many drawbacks in practical applications. When facing steel structure projects with different height requirements, fixed-height support frames often cannot be directly adapted, requiring construction personnel to spend a lot of time and manpower to modify them, or to replace them with support frames of different specifications. This not only leads to low construction efficiency, but also significantly increases construction costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable height steel structure support frame, including fixed rods, two fixed rods arranged in parallel, and the lower ends of the two fixed rods fixed together by a connecting plate, and a crossbar arranged in parallel above the connecting plate, the two ends of the crossbar being slidably connected to a notch on one of the fixed rods respectively;

[0006] A base is fixedly installed on the surface of the crossbar, and a movable rod is fixedly installed on the surface of the base. The movable rod is partially set in a positioning sleeve near its upper end, and the inner walls of the two sides of the positioning sleeve are respectively welded to the outer wall of a fixed rod.

[0007] In order to constrain the trajectory of the movable rod when it rises, as an adjustable height steel structure support frame of this utility model, preferably, two protective sleeves are symmetrically installed on the positioning sleeve, and a set of protruding beads are equally spaced on the outer wall of the opposite side of the two protective sleeves.

[0008] The two sheaths are located on the outer walls of the movable rod on both sides, and one side of the protruding ball is in contact with the outer wall of the movable rod.

[0009] The pedestal is located at the longitudinal midline of the crossbar, and the pedestal has a frustum structure with a maximum diameter greater than the inner diameter of the two sheath members.

[0010] In order to enable the crossbar to move upward effectively during use, as an adjustable height steel structure support frame of this utility model, preferably, an internal threaded sleeve is fixedly installed on the outer wall of the connecting plate facing the crossbar, and a screw is threaded through the other side of the crossbar, and the screw passes through the crossbar and is screwed out from the internal threaded sleeve.

[0011] The top end of the screw is fixedly connected to a docking post, the top end of the docking post is fixed in the inner ring of the bearing, the outer ring of the bearing is fitted inside the crossbar, the maximum vertical distance from the bottom of the connecting plate to the bottom of the fixed rod is greater than the maximum vertical length of the screw and the docking post, and the two ends of the crossbar are semi-circular structures.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, two fixed rods are secured to the corresponding ground surfaces. Then, the first screw is passed through the connecting plate and into the internal threaded sleeve. Rotating the screw moves it upwards. When the bearing at the top of the screw is inserted into the bearing, another screw needs to be connected to the bottom of the screw and rotated upwards. This allows the crossbar to be adjusted upwards. As the crossbar moves upwards, it drives the platform and movable rod upwards, allowing the movable rod to move closer to the steel structure that needs support. Ultimately, the movable rod will be stably supported at the bottom of the steel structure, thus achieving the desired support effect. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 The present invention provides the following technical solution: an adjustable height steel structure support frame, including a fixed rod 1, two fixed rods 1 are arranged in parallel, and the lower ends of the two fixed rods 1 are fixed together by a connecting plate 2. A crossbar 3 is arranged in parallel above the connecting plate 2, and the two ends of the crossbar 3 are slidably connected to a notch on a fixed rod 1 respectively.

[0021] A groove is provided on one side of each of the two fixed rods 1. The inner wall of one side of the groove is an arc-shaped structure. When the crossbar 3 moves, it will move in the groove between the two fixed rods 1, thereby preventing the crossbar 3 from deviating when it moves.

[0022] A base 4 is fixedly installed on the surface of the crossbar 3, and a movable rod 5 is fixedly installed on the surface of the base 4. The movable rod 5 is partially set in the positioning sleeve 6 near the upper end, and the inner walls on both sides of the positioning sleeve 6 are welded to the outer wall of a fixed rod 1 respectively.

[0023] Preferably, two protective sleeves 61 are symmetrically installed on the positioning sleeve 6, and a set of protruding beads 62 are equally spaced on the outer wall of the opposite side of the two protective sleeves 61;

[0024] Two sheaths 61 are located on the outer walls of the movable rod 5 on both sides, and one side of the protruding ball 62 is in contact with the outer wall of the movable rod 5.

[0025] When the movable rod 5 moves upward, its outer walls on both sides will slide smoothly along the outer wall of the protruding ball 62. At this time, under the restriction of the two sleeves 61 and the protruding ball 62, the movement trajectory of the movable rod 5 will be consistent, thus achieving the function of positioning and lifting.

[0026] The base 4 is located at the longitudinal midline of the crossbar 3, and the base 4 is a frustum structure. The maximum diameter of the base 4 is greater than the inner diameter of the two sheaths 61.

[0027] In practical use, when the middle platform 4 moves to its maximum stroke, the platform 4 will be restricted by the two protective sleeves 61, so that the middle platform 4 cannot continue to move upward. This can prevent excessive displacement from causing the structure to disintegrate.

[0028] Preferably, an internal threaded sleeve 21 is fixedly installed on the outer wall of the connecting plate 2 facing the crossbar 3, and a screw 22 is threaded through the other side of the crossbar 3. The screw 22 passes through the crossbar 3 and is screwed out from the internal threaded sleeve 21.

[0029] The top end of the screw 22 is fixedly connected to the docking post 23. The top end of the docking post 23 is fixed in the inner ring of the bearing 24. The outer ring of the bearing 24 is fitted inside the crossbar 3. The maximum vertical distance from the bottom of the connecting plate 2 to the bottom of the fixed rod 1 is greater than the maximum vertical length of the screw 22 and the docking post 23. The two ends of the crossbar 3 are semi-circular structures.

[0030] In practical use, the outer wall of the mating post 23 at one end of the screw 22 in this solution is provided with a threaded structure, and the bottom of the other end of the screw 22 is provided with a threaded groove. In use, two or more screws 22 can be assembled through the threaded connection between the corresponding screw 22 and the threaded groove, thereby extending the length of the screw 22.

[0031] In practical use, when adjusting the steel structure support, first fix the two fixing rods 1 to their corresponding ground positions. The fixing method can be selected according to the ground material. For example, expansion bolts can be used on hard ground, while ground anchors can be used on softer ground. Ensure that the fixing rods 1 are perpendicular to the ground and are firm and reliable to avoid shaking or displacement during subsequent operations.

[0032] Next, take the first screw 22 and thread it through the connecting plate 2 and into the internal threaded sleeve 21. After insertion, rotate the screw 22 clockwise. As the screw 22 rotates, due to the interaction of the threads, the screw 22 will move upward along the internal threaded sleeve 21. During the continuous upward movement of the screw 22, when the top of the screw 22 abuts the post 23 and inserts into the inner ring of the bearing 24, the screw 22 has reached its current maximum upward position.

[0033] If the support height is still insufficient to meet the actual requirements, another screw 22 needs to be connected to the bottom of the screw 22. When connecting, first connect the mating post 23 at one end of the new screw 22 to the threaded groove at the bottom of the original screw 22, and then continue to rotate the screw 22 assembly upwards.

[0034] As the screw 22 continues to rotate, the crossbar 3 will gradually adjust upwards under the drive of the screw 22. A stable connection exists between the crossbar 3, the base 4, and the movable rod 5. The upward movement of the crossbar 3 will synchronously drive the base 4 and the movable rod 5 upwards together. During the gradual ascent of the movable rod 5, the distance between it and the steel structure to be supported needs to be observed. By fine-tuning the rotation speed and amplitude of the screw 22, the movable rod 5 can accurately approach the steel structure.

[0035] Ultimately, the movable rod 5 will be firmly supported at the bottom of the steel structure, achieving a stable and reliable support effect for the corresponding steel structure, providing solid support for the steel structure, and meeting its construction requirements.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
