Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to an assembled steel support device. Background Technology

[0002] In modern building construction, especially in projects such as deep foundation pit support, bridge pier construction, and municipal integrated pipe gallery construction, the stability and safety of the supporting structure play a crucial role in project quality and construction safety.

[0003] Currently, in the internal support system of steel structure in foundation pit support engineering, the traditional steel support clamps and steel column connecting beams are connected by welding. Each steel support clamp is heavy and difficult to install. In addition, the welding workload is large and the welding quality is difficult to control. It is disassembled by gas cutting. After dismantling, most of them are scrapped, which greatly reduces the material turnover rate and increases the construction cost.

[0004] A search revealed a Chinese patent document disclosing a prefabricated clamp for steel supports in subway stations (Publication No.: CN220768092U). This utility model discloses a prefabricated clamp for steel supports in subway stations, belonging to the field of clamp technology. The clamp includes a steel support body, a bottom support device, side fixing devices, and a top fixing device. In use, the bottom of the steel support body is supported by the top of the bottom block. A tool is used to clamp the first hexagonal head and rotate it, driving a double-ended screw to rotate. The rotation of the double-ended screw drives the side fixing devices on both sides to move inward simultaneously, thus clamping the two sides of the steel support body. The tool is clamped to the outer wall of the second hexagonal head, rotating the shaft and protrusion, which in turn drives the second pulleys on both sides to rotate. The belts on both sides drive the first pulleys and second gears on both sides to rotate. The meshing of the second gear with the first gear drives the first gear and the threaded rod to rotate, allowing the top fixing device to move downward and fix the top of the steel support body, making the steel support body more stable. However, the following defects still exist:

[0005] While the aforementioned prefabricated support clamps can make the steel support body more stable, they also have other problems such as the large weight of a single steel support clamp, difficulty in installation, large amount of welding work, difficulty in controlling welding quality, and the need to use gas cutting to dismantle them. After dismantling, most of them are scrapped, which greatly reduces the material turnover rate and increases construction costs. Utility Model Content

[0062] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0063] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0064] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0065] like Figure 1-7 As shown, this application relates to a prefabricated steel support device. This prefabricated steel support device includes: a base 1; it can achieve a good fixed support effect, and at the same time, it can also achieve a good assembly effect with other components, thereby achieving multiple functional effects.

[0066] Two upright columns 3 are positioned opposite each other and perpendicularly on the top of the base 1, which can achieve good fixation, extension and support in the vertical direction.

[0067] A connector 13 is horizontally positioned between the two columns 3 and close to the top of the column 3; it can achieve a good fixed connection effect, thereby forming a semi-open frame structure.

[0068] Two locking members 27 are respectively arranged around the base 1 and connected to the bottom of the two columns 3 respectively; they can achieve a good locking effect, thereby ensuring the stability of the structure.

[0069] The two columns 3 and the connector 13 are detachably mounted on the base by the locking member 27 to fix steel supports of different models.

[0070] Specifically, the connector 13 is a horizontal connecting channel steel, the two columns 3 are vertical channel steel columns, and the locking part 27 is a U-bolt. The clamp formed by the three parts has pre-drilled bolt holes on the horizontal connecting channel steel. The vertical channel steel column is welded together from the bottom steel plate and the channel steel. The top of the vertical channel steel column has two pairs of pre-drilled bolt holes, and the bottom steel plate has four pre-drilled bolt holes. The U-bolt passes through the connecting beam and connects with the four pre-drilled bolt holes on the bottom steel plate of the vertical channel steel column, thus fixing the clamp as a whole to the connecting beam. The horizontal connecting channel steel and the vertical channel steel column are connected by bolts to achieve the function of steel support clamp.

[0071] like Figure 1 As shown, the prefabricated steel support device of this application can also be understood as a prefabricated steel support clamp. For different types of steel supports, the horizontal transverse connecting channel steel and the vertical channel steel column can be pre-assembled with bolts. After the clamp is placed in place, the clamp is fixed to the connecting beam with U-bolts to complete the installation and achieve the designed function of the steel support clamp.

[0072] Please see Figure 1-7The top of the base 1 has symmetrically arranged "concave" shaped mounting cavities 2, and the top of the mounting cavity 2 has a "concave" shaped column 3 inserted into it. One end of the column 3 is fixedly connected to a support column 4 with an inclined structure. The bottom side wall of the column 3 has a connecting cavity, and a series column 6 is installed through the inside of the connecting cavity. The series column 6 is installed through the inside of the series cavity 5. The series cavity 5 is located on the side wall of the base 1. The bottom end of the series column 6 has three slots 7, and each of the three slots 7 has a locking block 8. The locking block 8 is fixedly connected to the bottom of the connecting cavity 9. The inner side wall size of the connecting cavity 9 is adapted to the outer side wall size of the base 1.

[0073] During assembly, the column 3 is inserted into the top of the mounting cavity 2, and the series column 6 is inserted into the inside of the series cavity 5. The series column 6 is then inserted into the connecting cavity opened on the bottom side wall of the column 3. The base 1 is installed on the top of the connecting cavity 9, and the top of the locking block 8 is inserted into the bottom of the locking groove 7 to limit the position of the series column 6. This method eliminates the traditional bolt installation method, making the structure easier to assemble and disassemble during use, facilitating transportation and standardization of the installation process, improving installation efficiency and quality. At the same time, the installation process does not involve welding or cutting, reducing the difficulty of installation, increasing reusability, and reducing material loss.

[0074] The top outer wall of the column 3 is fixedly connected to the mounting sleeve 11 by fixing bolts 12, and the mounting sleeve 11 is fixedly connected to the connector 13. The connector 13 has a sliding cavity, and the sliding block 14 is slidably connected to both sides of the bottom of the sliding cavity. The mounting plate 16 is provided below the sliding block 14. The top of the mounting plate 16 and the sliding block 14 are symmetrically provided with support arms 15. The two support arms 15 are set in a figure-eight shape. The two ends of the two support arms 15 are respectively hinged to the top of the mounting plate 16 and the bottom of the sliding block 14 through movable shafts. The bottom of the mounting plate 16 and the top of the base 1 are fixedly connected to the balloon 17. The corresponding end of the balloon 17 is fixedly connected to a silicone anti-slip pad 18. The inner end of the balloon 17 is fixedly connected to an array of silicone protrusions 19. The balloon 17 is an inflatable structure.

[0075] During use, the relative movement of the sliding block 14 causes the sliding block 14 to drive the support arm 15 to move. The relative movement of the hinge point of the top support arm 15 then drives the mounting plate 16 to move downward, causing the balloon 17 to abut against the outer wall of the top of the tubular part. The balloons 17 set at the top and bottom then wrap around the outer wall of the tubular part. At the same time, the wrapping effect is improved by squeezing several silicone protrusions 19. In this way, the limiting method is more fitting and the limiting effect is further improved.

[0076] Both sides of the sliding cavity are rotatably connected to connecting screws 21, and the outer walls of the connecting screws 21 are meshed with transmission screw sleeves 20. The transmission screw sleeves 20 are fixedly connected inside the sliding block 14. One bevel gear 22 is fixedly connected to one end of each connecting screw 21 on both sides, and the top end of the first bevel gear 22 meshes with the bottom end of the second bevel gear 23. The second bevel gear 23 is rotatably connected inside the top end of the sliding cavity. A rotating knob 24 is rotatably connected to the top end of the sliding cavity, and the bottom end of the rotating knob 24 is drivenly connected to the top end of the second bevel gear 23. A guide cavity 25 is fixedly connected to the bottom end of the sliding cavity, and a guide block 26 is movably connected inside the bottom end of the guide cavity 25. The bottom end of the guide block 26 is fixedly connected to the top end of the mounting plate 16. A hexagonal groove is provided at the top end of the rotating knob 24.

[0077] During use, depending on the size of the tubular part to be limited, the knob 24 can be manually rotated to rotate forward or backward. The output device can be used in conjunction with the matching hexagonal column to drive the second bevel gear 23 to rotate. The second bevel gear 23 drives the first bevel gears 22 on both sides to rotate forward and backward respectively. Since the connecting screws 21 on both sides have the same tooth structure, the screw transmission structure formed by the transmission screw sleeve 20 and the connecting screw 21 allows the sliding block 14 to move relative or opposite to each other inside the sliding cavity, thereby driving the mounting plate 16 to move up and down.

[0078] Furthermore, the locking component 27 is a U-bolt, which is detachably connected to the column 3 via a locking accessory. The base 1, the two columns 3, and the connecting component 13 are all made of channel steel. This design allows for good assembly and disassembly; the use of channel steel also ensures good structural strength. The locking accessory can be a screw.

[0079] Furthermore, the column 3 has multiple first mounting holes 28 along a preset direction, and the connector 13 has multiple second mounting holes 10 corresponding to the first mounting holes. This achieves good assembly and fixing effect, and also allows for height adjustment, thus enabling flexible use. The preset direction can be horizontal.

[0080] Of course, the first mounting hole 28 and the second mounting hole 10 can also be in the shape of a through groove. This allows for easy position adjustment.

[0081] The specific usage process of this utility model is as follows:

[0082] First, insert the column 3 into the top of the mounting cavity 2 and insert the series column 6 into the inside of the series cavity 5, so that the series column 6 is inserted into the connecting cavity opened on the bottom side wall of the column 3, and install the base 1 on the top of the connecting cavity 9, so that the top of the card block 8 is inserted into the bottom of the card slot 7, thereby limiting the series column 6.

[0083] Secondly, by manually operating the knob 24 to rotate forward or reverse, and by using the output device in conjunction with the compatible hexagonal column, the second bevel gear 23 is driven to rotate, so that the second bevel gear 23 drives the first bevel gears 22 on both sides to rotate forward and reverse respectively. Since the connecting screws 21 on both sides are set with the same tooth structure, the screw transmission structure formed by the transmission screw sleeve 20 and the connecting screw 21 allows the sliding block 14 to move relative or opposite to each other inside the sliding cavity, thereby driving the mounting plate 16 to move up and down.

[0084] Finally, after the relative movement of the sliding block 14, the sliding block 14 drives the support arm 15 to move. Through the relative movement of the hinge point of the top support arm 15, the support arm 15 drives the mounting plate 16 to move downward, so that the balloon 17 abuts against the outer wall of the top of the tubular part. Then, the balloon 17 set at the top and bottom ends wraps around the outer wall of the tubular part, thus completing the use of the assembled steel support device.

[0085] In summary, this utility model has the following beneficial effects:

[0086] 1. This prefabricated steel support clamp can meet the installation requirements of two different diameter steel support clamps, A609mm and A800mm, which are commonly found on the market.

[0087] 2. The components of the clamp are connected by bolts, which makes it easy to adjust the size of the clamp according to the size of the steel support and flexibly apply to the installation of different models of steel supports.

[0088] 3. The clamps and connecting beams are connected and fixed by U-bolts and tie rods, making the installation process simple, efficient and convenient.

[0089] 4. The clamps can be completely disassembled after the structural construction is completed, with a high turnover rate, which greatly reduces material waste.

[0090] 5. The installation of the clamp does not involve welding or cutting, which reduces the difficulty of installation and lowers labor costs.

[0091] 6. The clamps adopt a standardized assembly installation method, which improves the installation quality and reduces the management costs of the construction unit.

[0092] 7. Applicable to the installation conditions of different types of steel support clamps, facilitating unified procurement and use; bolted connection, standardized installation process, improving installation efficiency and quality; no welding or cutting operations during installation, reducing installation difficulty; easy disassembly, high reusability, and low material loss.
