Description

Technical Field

[0001] This utility model relates to the field of building component technology, and in particular to a temporary fixing structure for steel structure columns. Background Technology

[0002] Currently, steel structure columns are commonly used as the main vertical load-bearing components in industrial plants, large-span public buildings, and high-rise buildings, as they have advantages such as good load-bearing capacity, high strength and stiffness, and stability and reliability.

[0003] During the assembly of steel structure buildings, steel structure columns require temporary support and fixation for erection. For example, Chinese utility model patent CN215168216U, with authorization announcement date of December 14, 2021, discloses a temporary fixing device and system for precast columns on backfill soil base layers. It includes a fixing component and a support component. The fixing component includes two vertically arranged fixing parts and a horizontal part connecting the two fixing parts. The bottom of the horizontal part has several spaced positioning elements for embedding into the backfill soil base layer and leveling the horizontal part. In the installed state, one end of the fixing component is tightly fitted with the precast column, and the length direction of the horizontal part and the height direction of the precast column respectively form the two legs of a right triangle. Both ends of the support component are connected to the horizontal part and the precast column respectively to temporarily fix the precast column.

[0004] The existing support components of the temporary fixing device for precast columns are connected to the precast bolt holes in the precast columns via bolt connectors. However, pre-drilling bolt holes in the steel structure will damage the integrity of the column structure, and it is difficult to drill holes on site, resulting in low construction efficiency for temporary fixing of steel structures. Utility Model Content

[0005] The technical problem this utility model aims to solve is that reserving bolt holes on steel structures will damage the integrity of the column structure, drilling holes on site is difficult, and the construction efficiency of temporary fixing of steel structures is low.

[0006] To solve the above-mentioned technical problems, this utility model provides a technical solution for a temporary fixing structure for steel structure columns: the temporary fixing structure for steel structure columns includes a pad layer, a steel structure column, a first clamp, a second clamp, a fixing seat, a first support member, a second support member, and a third support member. The steel structure column is vertically arranged on the pad layer. The first clamp and the second clamp are detachably installed on the steel structure column, and the first clamp and the second clamp are distributed vertically at intervals.

[0007] Multiple first support members are provided, and the multiple first support members are connected between the first clamp and the second clamp; multiple fixing seats are provided, and the multiple fixing seats are provided on the pad layer and are distributed circumferentially with respect to the second clamp;

[0008] The second support member is provided in multiple ways. The second support member is fixed between the second clamp and the fixed seat. The second support member extends parallel to the upper side of the pad layer. The third support member is provided in multiple ways. The third support member is fixed between the first clamp and the fixed seat. The third support member extends obliquely within the right angle between the pad layer and the steel structure column.

[0009] Furthermore, the first clamp includes two symmetrically arranged first U-shaped clamps, the ends of the first U-shaped clamps are provided with first ear plates, and a first fastener is detachably installed between the first ear plates of the two first U-shaped clamps;

[0010] The second clamp includes two symmetrically arranged second U-shaped clamps, the ends of which are provided with second ear plates, and a second fastener is detachably installed between the second ear plates of the two second U-shaped clamps.

[0011] Furthermore, the first ear plate, the second ear plate, and part of the fixing seat are in the same vertical plane, one end of part of the third support member is fixedly connected to at least one first ear plate, and one end of part of the second support member is fixedly connected to at least one second ear plate.

[0012] Furthermore, the first U-shaped clamp has a third ear plate on the side away from the opening, and the second U-shaped clamp has a fourth ear plate on the side away from the opening. The third ear plate, the fourth ear plate, and part of the fixing seat are in the same vertical plane, and one end of part of the third support member is fixedly connected to the third ear plate.

[0013] Furthermore, an L-shaped plate is provided on the outer side of the edge of the first U-shaped clamp corresponding to the steel structure column. The L-shaped plate is in the horizontal plane and is clamped and fixed to the outer corner of the first U-shaped clamp.

[0014] The second U-shaped clamp has an L-shaped block on the outer side of the edge of the steel structure column. The L-shaped block is located on the pad and is fixedly engaged with the outer corner of the second U-shaped clamp. The first support member is adjustablely connected between the L-shaped plate and the L-shaped block.

[0015] Furthermore, the L-shaped plate has a first hole, the L-shaped block has a second hole, and the first support member is a long screw rod, which is inserted and connected to the first hole and the second hole.

[0016] Furthermore, the fixing base includes a base plate and two side plates, the two side plates are fixedly connected to the middle of the base plate and are arranged in parallel and spaced apart, and the other end of the second support member and the other end of the third support member are respectively fixedly connected to at least one of the side plates.

[0017] Furthermore, the base plate has a third hole, and the pad layer is also provided with anchor bolts corresponding to the fixing seat, and the anchor bolts are inserted into the third hole;

[0018] The other end of the second support member and the other end of the third support member are both inserted into the gap between the two side plates. The two side plates are respectively provided with a fourth hole, and a fourth fastener is inserted through the fourth hole. The fourth fastener connects the side plate to the second support member or the side plate to the third support member.

[0019] Furthermore, both the second support member and the third support member are strip steel plates.

[0020] Compared with existing technologies, the temporary fixing structure for steel columns of this utility model has the following advantages: This temporary fixing structure for steel columns adopts a design consisting of a pad layer, a steel column, a first clamp, a second clamp, fixing seats, a first support member, a second support member, and a third support member. The first and second clamps are detachably installed on the steel column and are spaced vertically. The first support member connects the first and second clamps, maintaining the spacing and relative vertical position of the two clamps. Multiple fixing seats are located on the pad layer and are spaced circumferentially about the second clamp. Multiple second support members connect the second clamp to the multiple fixing seats. The second clamp and the multiple second support members reliably limit the bottom position of the steel column, ensuring that the bottom of the steel column remains stable on the pad layer.

[0021] The system comprises multiple third supports connected to the first clamp and several fixed seats. These third supports extend obliquely within the right angle between the pad layer and the steel structure column, providing support from all sides and generating oblique support force and resistance to overturning moment, thus forming a spatial three-dimensional support system. The first and second clamps serve as temporary anchor points for the steel structure column, avoiding the need for pre-drilled bolt holes that could compromise the column's integrity. On-site assembly of the clamps is also easier, improving the efficiency of temporary steel structure fixing. Furthermore, the fixed seats serve as the foundation anchor points for the entire system, enhancing the lateral displacement and overturning stability of the steel structure column in its upright position.

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0032] like Figures 1 to 5 As shown, a temporary fixing structure for a steel column according to an embodiment of the present invention includes a pad layer 1, a steel column 2, a first clamp 3, a second clamp 4, a fixing seat 5, a first support member 6, a second support member 7, and a third support member 8. The steel column 2 is vertically mounted on the pad layer 1. The first clamp 3 and the second clamp 4 are detachably mounted on the steel column 2, and the first clamp 3 and the second clamp 4 are distributed vertically at intervals. Multiple first support members 6 are provided, and multiple first support members 6 are connected between the first clamp 3 and the second clamp 4.

[0033] Multiple fixing seats 5 are provided, which are located on the pad 1 and are distributed circumferentially around the second clamp 4; multiple second support members 7 are provided, which are fixed between the second clamp 4 and the fixing seats 5, and extend parallel to the upper side of the pad 1; multiple third support members 8 are provided, which are fixed between the first clamp 3 and the fixing seats 5, and extend obliquely within the right angle between the pad 1 and the steel structure column 2.

[0034] The temporary fixing structure for the steel column adopts a design consisting of a pad layer 1, a steel column 2, a first clamp 3, a second clamp 4, fixing seats 5, a first support member 6, a second support member 7, and a third support member 8. The first clamp 3 and the second clamp 4 are detachably installed on the steel column 2 and are spaced apart vertically. The first support member 6 connects the first clamp 3 and the second clamp 4, maintaining the spacing and relative vertical position of the two clamps. Multiple fixing seats 5 are located on the pad layer 1 and are spaced apart circumferentially about the second clamp 4. Multiple second support members 7 connect the second clamp 4 to the multiple fixing seats 5. The second clamp 4 and the multiple second support members 7 reliably limit the bottom position of the steel column 2, ensuring that the bottom of the steel column 2 remains stable on the pad layer 1.

[0035] In this system, multiple third support members 8 connect the first clamp 3 to multiple fixing seats 5. These third support members 8 extend obliquely within the right angle between the pad layer 1 and the steel structure column 2. They act as abutments against the column from all sides, generating oblique support force and resisting overturning moment, thus forming a spatial three-dimensional support system. The first clamp 3 and the second clamp 4 serve as temporary anchor points for the steel structure column 2, avoiding the need for pre-drilled bolt holes in the steel structure that could compromise its integrity. On-site assembly of the clamps is also easier, improving the construction efficiency of temporary steel structure fixing. Furthermore, the fixing seats 5 serve as the foundation anchor points for the entire system, enhancing the lateral displacement and overturning stability of the steel structure column 2 in its upright position.

[0036] In this embodiment, the first clamp 3 includes two symmetrically arranged first U-shaped clamps 30, each with a first ear plate 31 at its end. A first fastener (not shown in the figure) is detachably installed between the first ear plates 31 of the two first U-shaped clamps 30. The second clamp 4 includes two symmetrically arranged second U-shaped clamps 40, each with a second ear plate 41 at its end. A second fastener (not shown in the figure) is detachably installed between the second ear plates 41 of the two second U-shaped clamps 40. The first clamp 3 is clamped to the upper part of the steel structure column 1 by the two symmetrical first U-shaped clamps 30, and the second clamp 4 is clamped to the bottom of the steel structure column 1 by the two symmetrical second U-shaped clamps 40. The clamp-on fastener assembly method is simple and reliable, facilitating on-site assembly and disassembly.

[0037] As a further preferred embodiment, the first ear plate 31, the second ear plate 41, and part of the fixing seat 5 are located in the same vertical plane. One end of part of the third support member 8 is fixedly connected to at least one first ear plate 31, and one end of part of the second support member 7 is fixedly connected to at least one second ear plate 41. That is to say, the first ear plate 31 and the second ear plate 41 not only serve as the connection points for the two U-shaped clamps to interlock, but also as the connection points for the first clamp 3 and part of the third support member 8, and the second clamp 4 and part of the second support member 7.

[0038] Furthermore, the first U-shaped clamp 30 has a third ear plate 32 on the side away from the opening, and the second U-shaped clamp 40 has a fourth ear plate 42 on the side away from the opening. The third ear plate 32, the fourth ear plate 42, and part of the fixing seat 5 are in the same vertical plane, and one end of part of the third support member 8 is fixedly connected to the third ear plate 32. The first ear plate 31 and the third ear plate 32 form the connection points on the four sides of the first clamp 3, and the second ear plate 41 and the fourth ear plate 42 form the connection points on the four sides of the second clamp 4, which can provide limiting support for the steel structure column 2 from four directions.

[0039] like Figure 3 , Figure 4 As shown, the first U-shaped clamp 30 has an L-shaped plate 33 on the outer side of the edge of the steel structure column 2. The L-shaped plate 33 is in the horizontal plane and is fixedly engaged with the outer corner of the first U-shaped clamp 30. The second U-shaped clamp 40 has an L-shaped block 43 on the outer side of the edge of the steel structure column 2. The L-shaped block 43 is located on the pad layer 1 and is fixedly engaged with the outer corner of the second U-shaped clamp 40. The first support member 6 is adjustablely connected between the L-shaped plate 33 and the L-shaped block 43. That is, the first support member 6 is located at the four edges of the steel structure column 2, offset from the positions of the second support member 7 and the third support member 8, to prevent inconvenience in disassembly and assembly due to easy interference.

[0040] Specifically, the L-shaped plate 33 has a first hole, the L-shaped block 43 has a second hole, the first support member 6 is a long screw, the first support member 6 is inserted and connected in the first hole and the second hole, and is installed in the first support member 6 by a nut, thereby playing a vertical limiting role for the first clamp 3 and the second clamp 4.

[0041] like Figure 5 As shown, the fixing base 5 includes a base plate 51 and two side plates 52. The two side plates 52 are fixedly connected to the middle of the base plate 51 and are arranged in parallel and spaced apart. The other end of the second support member 7 and the other end of the third support member 8 are respectively fixedly connected to at least one side plate 52. Furthermore, the base plate 51 has a third hole 53, and the pad layer 1 is also provided with anchor bolts (not shown in the figure) corresponding to the fixing base 5. The anchor bolts are inserted into the third hole 53.

[0042] Furthermore, the other end of the second support member 7 and the other end of the third support member 8 are inserted into the gap between the two side plates 52. The two side plates 52 have corresponding fourth holes 54, through which fourth fasteners are inserted. These fourth fasteners connect the side plates 52 to the second support member 7 or the side plates 52 to the third support member 8. Moreover, both the second support member 7 and the third support member 8 are strip steel plates, ensuring a stable connection between the second support member 7, the third support member 8, and the fixing base 5.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
