Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a height-adjustable steel support structure. Background Technology

[0002] In fields such as building construction, bridge construction, and equipment installation, steel supports serve as crucial temporary support structures, playing a vital role in maintaining construction stability and safety. However, with the accelerating pace of modern engineering construction and the increasing precision requirements, the structural complexity and adjustment limitations of traditional steel supports are becoming increasingly prominent.

[0003] As an important temporary load-bearing structure, steel supports have their brackets in direct contact with the supported components. However, traditional steel supports generally use welded fixed brackets or single-type adjustable brackets. When different shapes or specifications of components need to be supported on the construction site, multiple sets of special support equipment are often required, or adjustments are made through rough methods such as temporary welding and padding. This not only increases equipment costs and storage pressure, but also makes the process of replacing brackets on site cumbersome and affects construction efficiency. Utility Model Content

Several brackets with different structural dimensions or load-bearing characteristics can be individually and alternately installed on top of the first threaded adjustment assembly according to usage requirements. All brackets are located at the cantilevered end of the first threaded adjustment assembly away from the support column. Thus, by rotating the first threaded adjustment assembly, the brackets are driven to move closer to or further away from the support column, achieving adjustment of the distance between the brackets and the support column. Brackets can be quickly selected and replaced according to the different shapes and specifications of the supported components. Combined with the stepless height adjustment function provided by the first threaded adjustment assembly, a single support structure can be widely adapted to diverse construction conditions, thereby effectively reducing equipment configuration costs and improving construction efficiency.

[0008] According to some embodiments of the present invention, a second threaded adjustment assembly is also included. One end of the second threaded adjustment assembly is connected to the support column, and the other end is connected to the base. The second threaded adjustment assembly is used to control the base to move closer to or further away from the support column.

[0009] According to some embodiments of the present invention, the second threaded adjustment assembly includes: two second connecting seats, one of which is connected to the base and the other of which is connected to the support column; and a second bidirectional threaded rod, one of which is connected to the second bidirectional threaded rod by a forward thread engagement and the other of which is connected to the second bidirectional threaded rod by a reverse thread engagement.

[0031] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] Reference Figure 1 This utility model discloses a height-adjustable steel support structure, including a base 100, a support column 200, a first threaded adjustment component 300, and several brackets 400. The support column 200 is disposed on the base 100. One end of the first threaded adjustment component 300 is connected to the support column 200. Several brackets 400 can be individually and alternately installed on the first threaded adjustment component 300. The brackets 400 are located at the end of the first threaded adjustment component 300 away from the support column 200. The first threaded adjustment component 300 is used to control the brackets 400 to move closer to or further away from the support column 200. The brackets 400, the first threaded adjustment component 300, the support column 200, and the base 100 are connected in sequence.

[0035] like Figure 1 and Figure 3As shown, the base 100 is provided with a support column 200, a first threaded adjustment assembly 300, and several brackets 400 of different specifications arranged sequentially from bottom to top. The support column 200 is vertically fixed to the base 100. One end of the first threaded adjustment assembly 300 is connected to the top of the support column 200, and the other end is connected to the bottom of the bracket 400. Several brackets 400 with different structural dimensions or load-bearing characteristics can be individually and alternately installed on the top of the first threaded adjustment assembly 300 according to usage requirements. All brackets 400 are located at the cantilevered end of the first threaded adjustment assembly 300 away from the support column 200. Therefore, by rotating the first threaded adjustment component 300, the bracket 400 is driven to move in the direction of approaching or moving away from the support column 200, thereby realizing the adjustment of the distance between the bracket 400 and the support column 200. The bracket 400 can be quickly selected and replaced according to the different shapes and specifications of the supported components. Combined with the stepless height adjustment function provided by the first threaded adjustment component 300, a single support structure can be widely adapted to diverse construction conditions, thereby effectively reducing the configuration cost of the equipment and improving construction efficiency.

[0036] It should be noted that the bracket 400 can be configured in two typical structural forms: one is a ball-head connector bracket with a ball-and-socket joint, such as... Figure 4 As shown, it has a hemispherical socket that matches the ball head of the steel structure, and the ball head can be adjusted and locked in all directions by tightening bolts. It is suitable for node support that requires multi-angle connection; another type is the planar support type bracket 400, such as... Figure 1 and Figure 2 As shown, I-beams or channel steel sections are used as the main load-bearing components, and the upper surface is machined with anti-slip textures or equipped with rubber buffer pads, which are specifically used for direct support of planar components such as beams and slabs.

[0037] It should be noted that the appropriate form of the base 100 can be selected according to the construction environment, such as rectangular, polygonal or cross-shaped, to ensure that the base 100 has good contact with the ground, thereby facilitating the adjustment of the level of the base 100.

[0038] It should be noted that construction auxiliary tools 10 include equipment such as levels and laser positioning devices.

[0039] Furthermore, in the technical solution of this utility model, the overall surface of the structure is coated with an anti-corrosion coating, which can adapt to humid, dusty or corrosive environments.

[0040] In some specific embodiments of this utility model, the first threaded adjustment assembly 300 includes: two first connecting seats 310 and a first bidirectional threaded rod 320, one of the first connecting seats 310 being connected to the bracket 400 and the other first connecting seat 310 being connected to the support column 200; one of the first connecting seats 310 and the first bidirectional threaded rod 320 are connected by a forward thread engagement, and the other first connecting seat 310 and the first bidirectional threaded rod 320 are connected by a reverse thread engagement.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, two first connecting seats 310 are arranged vertically and connected by a first bidirectional threaded rod 320. The first connecting seat 310 connected to the top of the first bidirectional threaded rod 320 is detachably connected to the bottom of the bracket 400, and the first connecting seat 310 connected to the bottom of the first bidirectional threaded rod 320 is fixedly connected to the top of the support column 200. It should be noted that the two ends of the first bidirectional threaded rod 320 are respectively provided with threaded sections with opposite directions of rotation. The two first connecting seats 310 engage with the first bidirectional threaded rod 320 through forward and reverse threads, respectively. When the bidirectional threaded rod is rotated, the two first connecting seats 310 will move synchronously towards or away from each other, thereby adjusting the distance between the bracket 400 and the support column 200, while enhancing the overall rigidity and stability of the support structure.

[0042] Furthermore, both the forward and reverse threaded sections of the first bidirectional threaded rod 320 are clearly marked with thread specifications, and corresponding mating marks are marked on the corresponding first connecting seat 310. Through this visual dimensioning, operators can intuitively identify the thread direction and mating relationship, ensuring correct alignment during assembly. Specifically, during adjustment, these markings can serve as reference benchmarks, helping operators accurately determine the adjustment direction and displacement, thereby achieving precise control of the distance between the bracket 400 and the support column 200.

[0043] Furthermore, a locking element is provided at the mating part between the first bidirectional threaded rod 320 and the first connecting seat 310. When adjusted to the target position, the locking element can generate a preload between the first connecting seat 310 and the first bidirectional threaded rod 320, thereby eliminating the mating clearance of the threaded pair and effectively preventing relative displacement that may occur under vibration or load changes. The locking element of this utility model can be implemented in various ways, including but not limited to a locking nut structure, a set screw locking structure, a wedge locking structure, and a combined locking structure. Specifically, the locking nut structure adds a locking nut to the mating end of the first connecting seat 310 and the first bidirectional threaded rod 320, and achieves friction locking by tightening the nut so that its end face presses against the connecting seat; the set screw locking structure uses a threaded set screw provided on the side of the first connecting seat 310 to directly press against the tooth surface of the first bidirectional threaded rod 320 to form a mechanical limit; the wedge locking structure uses a radially adjustable wedge block inside the first connecting seat 310, and the wedge surface is driven by a bolt to press against the tooth side of the first bidirectional threaded rod 320; the combined locking uses an anti-loosening nut and an elastic element to form a double locking system. These locking methods can effectively prevent relative displacement of the threaded pair while maintaining adjustment accuracy, ensuring the long-term stability of the support structure.

[0044] In some specific embodiments of this utility model, a second thread adjustment component 500 is also included. One end of the second thread adjustment component 500 is connected to the support column 200, and the other end is connected to the base 100. The second thread adjustment component 500 is used to control the base 100 to move closer to or further away from the support column 200.

[0045] like Figure 1 As shown, the base 100 is provided with, from bottom to top, a second threaded adjustment assembly 500, a support column 200, a first threaded adjustment assembly 300, and several brackets 400 of different specifications. In this specific embodiment, the support column 200 is vertically fixed to the second threaded adjustment assembly 500. One end of the second threaded adjustment assembly 500 is connected to the top of the base 100, and the other end is connected to the bottom of the support column 200. When the second threaded adjustment assembly 500 is rotated, the support column 200 can be driven to move up and down along its axis, thereby forming a dual adjustment system with the first threaded adjustment assembly 300. This system can independently adjust the contact state between the base 100 and the ground to adapt to uneven foundations, and can also work with the first threaded adjustment assembly 300 to achieve a composite adjustment of the support height, significantly improving the terrain adaptability of the entire support structure.

[0046] In some specific embodiments of this utility model, the second threaded adjustment assembly 500 includes two second connecting seats 510 and a second bidirectional threaded rod 520. One of the second connecting seats 510 is connected to the base 100, and the other second connecting seat 510 is connected to the support column 200. One of the second connecting seats 510 and the second bidirectional threaded rod 520 are connected by a forward thread engagement, and the other second connecting seat 510 and the second bidirectional threaded rod 520 are connected by a reverse thread engagement.

[0047] like Figure 1 and Figure 2 As shown, two second connecting seats 510 are arranged vertically, and two first connecting seats 310 are connected by a second bidirectional threaded rod 520. The second connecting seat 510 connected to the top of the second bidirectional threaded rod 520 is fixedly connected to the support column 200, and the second connecting seat 510 connected to the bottom of the second bidirectional threaded rod 520 is connected to the top of the base 100. It should be noted that the two ends of the second bidirectional threaded rod 520 are respectively provided with threaded sections with opposite directions of rotation, and the two second connecting seats 510 are engaged with the bidirectional threaded rod through forward and reverse threads, respectively. When the second bidirectional threaded rod 520 is rotated, the two connecting seats will move synchronously in opposite directions, thereby realizing the height adjustment of the support column 200 relative to the base 100. This not only ensures the smoothness and synchronization accuracy of the adjustment process, but also effectively maintains the overall stability of the support structure, making it particularly suitable for working environments that require fine adjustment of the level of the base 100.

[0048] It should be noted that the thread marking structure and all technical features and implementation methods of the locking element of the first thread adjustment component 300 are also applicable to the second thread adjustment component 500. That is, the positive thread section and the reverse thread section of the second bidirectional threaded rod 520 are also marked with specification markings, and the second connecting seat 510 is marked with corresponding mating marks. The same type of locking element structure can be used to achieve precise adjustment and reliable locking of the second thread adjustment component 500. Further details will not be elaborated here.

[0049] In some specific embodiments of this utility model, the second connecting seat 510 is connected to the base 100 via a spherical hinge.

[0050] like Figure 1 and Figure 2As shown, the second connecting seat 510 and the base 100 are connected by a spherical hinge structure. Specifically, the spherical hinge includes a hemispherical hinge groove at the bottom of the second connecting seat 510 and a ball head support fixed to the base 100. The two form a three-dimensional movable connection through spherical mating. Thus, when the second threaded adjustment assembly 500 is height adjusted, the base 100 can adapt to changes in ground inclination and automatically compensate for flatness deviations. This ensures the precise adjustment function of the threaded transmission and effectively eliminates the additional bending moment caused by uneven foundation through multi-directional rotational freedom, significantly improving the stability and load transfer efficiency of the support system under complex terrain conditions.

[0051] It should be noted that the hemispherical hinge groove can be set on the base 100, and correspondingly, the ball head support can be fixedly set at the bottom of the second connecting seat 510.

[0052] In some specific embodiments of this utility model, the bottom of the base 100 is provided with an anti-slip part 110. The anti-slip part 110 of this utility model can be implemented in various ways, including but not limited to processing staggered anti-slip patterns on the bottom surface of the base 100, embedding a high-friction coefficient rubber pad layer, setting a removable anti-slip nail plate, and arranging an array of raised particles. The anti-slip part 110 can effectively prevent relative slippage between the base 100 and the foundation surface when bearing vertical loads, which is beneficial for construction operations that require resistance to horizontal forces, such as temporary support of steel structures and formwork engineering.

[0053] In some specific embodiments of this utility model, a fixing member 600 is also included. The fixing member 600 is detachably mounted on the support column 200 and is used to fix the construction auxiliary tool 10 to the support column 200. Figure 1 , Figure 2 and Figure 3 As shown, the support column 200 is equipped with a detachable fastener 600 for installing various construction auxiliary tools 10. It should be noted that the construction auxiliary tools 10 can be measuring instruments such as fixed levels, laser locators, or tilt sensors. In this specific embodiment, taking a level as an example, the level can be directly embedded in the mounting groove of the fastener 600, ensuring that the instrument axis remains precisely parallel to the reference plane of the support column 200. This satisfies the need for real-time monitoring of the support system's status during construction while avoiding material damage caused by welding mounting seats to the support structure, achieving a balance between functional expansion and structural integrity.

[0054] Furthermore, the fastener 600 may take the form of a quick-clamping mechanism or a magnetic mounting base.

[0055] In some specific embodiments of this utility model, the fixing member 600 is provided with a pin 610, and the support column 200 is provided with a socket 210 adapted to the pin 610. When the pin 610 is inserted into the socket 210, the fixing member 600 is connected to the support column 200. Specifically, the back of the fixing member 600 is provided with at least two positioning pins 610, and the support column 200 is axially spaced with several sets of sockets 210 that match the pins 610. During installation, the operator can select different height sets of sockets 210 for insertion according to monitoring needs, thereby realizing the rapid positioning of the construction auxiliary tool 10 at any calibrated height on the support column 200. This maintains the rigid connection characteristics of the instrument installation and achieves operational convenience, making it particularly suitable for construction scenarios that require real-time monitoring of multiple points.

[0056] Furthermore, the end of the plug 610 is provided with an elastic buckle, so that when the plug 610 is inserted into the socket 210, the elastic buckle at the end of the plug 610 can automatically lock to prevent it from falling off.

[0057] Furthermore, the pins 610 and the sockets 210 are made of rust-resistant metal and have guide chamfers to ensure the fitting accuracy during repeated disassembly and assembly.

[0058] In some specific embodiments of this utility model, the support column 200 includes an inner cylinder 220 and an outer cylinder 230. The inner cylinder 220 passes through the outer cylinder 230 and can slide along the axial direction of the outer cylinder 230. The inner cylinder 220 is connected to the first threaded adjustment assembly 300, and the outer cylinder 230 is connected to the base 100.

[0059] like Figure 3 As shown, in another specific embodiment of this utility model, the support column 200 adopts a double-layer sleeve-type telescopic structure, including an inner cylinder 220 and an outer cylinder 230 coaxially configured. The inner cylinder 220 is fitted inside the outer cylinder 230 with a clearance fit and can slide telescopically along the axial direction of the outer cylinder 230. The upper end of the inner cylinder 220 is fixedly connected to the first threaded adjustment assembly 300, while the lower end of the outer cylinder 230 is directly rigidly connected to the base 100. Thus, the overall height of the support column 200 is coarsely adjusted by the relative sliding of the inner cylinder 220 and the outer cylinder 230, and the bracket 400 is precisely finely adjusted by the first threaded adjustment assembly 300, forming a two-stage adjustment system.

[0060] In some specific embodiments of this utility model, the inner cylinder 220 and the outer cylinder 230 are connected by a pin structure 240. For example... Figure 3As shown, the inner cylinder 220 and the outer cylinder 230 are positioned and height locked by a pin structure 240. Specifically, the outer cylinder 230 has several sets of through first positioning holes spaced apart along its axial direction, and the inner cylinder 220 has equidistant second positioning holes at corresponding positions. When the inner cylinder 220 slides to the target height, the pin structure 240 is inserted into the first positioning hole of the outer cylinder 230 and the second positioning hole of the inner cylinder 220 at the same time to form a mechanical interlock.

[0061] In the technical solution of this utility model, such as Figure 5 As shown, the pin structure 240 consists of two semi-circular components 241 and a pin 242. The two semi-circular components form an openable mechanism through a hinge shaft. One end of the pin 242 is coaxially connected to the hinge shaft and extends radially, with a connecting piece at its end having a connecting hole. When locking is required, the extended pin 242 is first inserted into the corresponding positioning holes of the inner cylinder 220 and the outer cylinder 230. Then, the two semi-circular components are closed, so that the connecting piece at its end and the connecting piece of the pin 242 form a three-layer overlapping structure. At this time, the through holes of the three connecting pieces are precisely aligned. Finally, the secondary pin is inserted to complete the overall fixation. Thus, the balanced transmission of multi-directional force is achieved through the overlapping fixation of the three-layer connecting pieces, enabling the overall structure to maintain excellent shear resistance even when subjected to eccentric loads.

[0062] The following describes the height-adjustable steel support structure based on two specific embodiments.

[0063] Example 1:

[0064] The support column 200 is vertically positioned, with its top end connected to the bracket 400 via a first threaded adjustment assembly 300, and its bottom connected to the base 100 via a second threaded adjustment assembly 500. The base 100 has anti-slip textured surfaces on its bottom to enhance stability. The first threaded adjustment assembly 300 includes two first connecting seats 310 and a first bidirectional threaded rod 320. One first connecting seat 310 is fixedly connected to the bracket 400, while the other first connecting seat 310 is connected to the top end of the support column 200. The forward and reverse threads of the first bidirectional threaded rod 320 respectively form a transmission engagement with the two first connecting seats 310, allowing for precise height adjustment of the bracket 400 by rotating the first bidirectional threaded rod 320. The second threaded adjustment assembly 500 includes two second connecting seats 510 and a second bidirectional threaded rod 520. One second connecting seat 510 is fixedly connected to the base 100, and the other second connecting seat 510 is connected to the bottom end of the support column 200. The forward and reverse threads of the second bidirectional threaded rod 520 respectively form a transmission engagement with the two second connecting seats 510. The second connecting seat 510 located at the bottom is connected to the base 100 through a ball joint, enabling the base 100 to adapt to the ground angle. The support column 200 is provided with multiple sets of insertion holes 210, which can be quickly inserted into the pins 610 on the back of the fixing member 600 for installing auxiliary instruments such as levels.

[0065] In use, construction personnel first quickly select and replace brackets 400 according to the different shapes and specifications of the supported components. Then, the entire structure is placed on the work surface, and initial leveling is achieved by observing the level on the support column 200. When encountering uneven foundations, the bidirectional threaded rod of the second threaded adjustment component 500 can be rotated. At this time, the two second connecting seats 510 move synchronously under the action of the forward and reverse threads, driving the base 100 to rise and fall relative to the support column 200. Simultaneously, the spherical hinge structure automatically adapts to changes in ground inclination, achieving rapid leveling of the base 100. After completing the foundation leveling, the operator selects the appropriate bracket 400 according to the support requirements and installs it on the first threaded adjustment component 300. By rotating the first bidirectional threaded rod 320, the bracket 400 is moved to the target height position. After it is in place, the locking piece on the first connecting seat 310 is tightened to fix it. During construction, technicians can insert the pins 610 of the fixing component 600 into the insertion holes 210 at different heights on the support column 200 at any time to quickly install monitoring instruments for structural condition checks. The entire adjustment process requires no welding or special tools, and a single person can complete all height adjustments and function expansion operations, significantly improving construction efficiency and safety.

[0066] Example 2:

[0067] The support column 200 adopts a double-layer sleeve-type telescopic structure, including an inner cylinder 220 and an outer cylinder 230 coaxially configured. The inner cylinder 220 can slide along the axial direction of the outer cylinder 230 to adjust the overall height. The inner cylinder 220 and the outer cylinder 230 are locked in position by a pin structure 240. The bottom of the base 100 is provided with anti-slip texture to enhance stability, and the lower end of the outer cylinder 230 is directly fixedly connected to the base 100. The upper end of the inner cylinder 220 is connected to the first threaded adjustment assembly 300. The first threaded adjustment assembly 300 includes two first connecting seats 310 and a first bidirectional threaded rod. One of the first connecting seats 310 is connected to the bracket 400, and the other first connecting seat 310 is connected to the inner cylinder 220. The forward and reverse threads of the first bidirectional threaded rod 320 respectively cooperate with the two first connecting seats 310. By rotating the first bidirectional threaded rod 320, the precise height adjustment of the bracket 400 can be achieved. During construction, different types of brackets 400 can be selected and alternately installed on the first connecting seats 310 as needed. The positioning holes spaced axially on the support column 200 serve both for locking the height of the inner cylinder 220 and the outer cylinder 230, and as mounting holes 210 for the fastener 600, facilitating the quick installation of construction monitoring instruments such as levels. It should be noted that in this embodiment, the support column 200 achieves coarse height adjustment through the extension and retraction of the inner cylinder 220 and the outer cylinder 230. Combined with the precision adjustment of the first threaded adjustment assembly 300, a wide range of adjustable support height and precise positioning are achieved without the need for a second threaded adjustment assembly 500, while also ensuring ease of operation and structural stability.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
