Description

Technical Field

[0001] The invention relates to the technical field of steel structure assembly, and in particular to a connection node for connecting a support frame and a transfer beam. Background Art

[0002] The components and forms of the support frame and structure connection are varied. Different designs and connection methods are usually required according to different engineering requirements and environmental conditions. Common connection methods include bolt connection, anchor connection, sliding / telescopic connection, modular quick-install connection and plug-in (mortise and tenon) connection.

[0003] The invention patent with publication number CN116290916A discloses a connection node suitable for connecting a support frame and a transfer beam for heavy-duty assembled components, including a bottom transfer beam and a temporary support frame erected on the bottom transfer beam, and the transfer beam and the temporary support frame are connected by bolts.

[0004] The invention patent with publication number CN116950233A discloses a supporting frame group structural system, in which the supporting frame is connected to the conversion beam through a connecting member, and the connecting member includes a clamping plate located on the conversion beam and a high-strength bolt for connecting the clamping plate to the supporting frame.

[0005] The invention patent with publication number CN214091149U discloses a novel column foot device of a standard support frame, including a support frame fixedly connected to the ground, characterized in that it also includes a column foot fixedly connected to the upper surface of the support frame, a flange fixedly connected to the top of the column foot, and a mounting hole located on the flange, the flange being detachably connected to the bottom of the standard support frame through the mounting hole and a bolt assembly, at least three column feet are arranged, and at least three column feet are evenly distributed on the upper surface of the support frame.

[0006] However, the above devices all have their limitations. In the above support frame system, whether ordinary bolts or high-strength bolts are used as the connection nodes between the support frame and the conversion beam, due to the limited connection strength of the bolts, the support frame system may deform and fail under heavy loads and long-term use. As an alternative, although the anchor connection between the support frame and the conversion beam through pre-buried anchor bolts has a higher connection strength, it also brings the disadvantage of being difficult to adjust or shift. The support frame can only be dismantled by cutting the support frame column foot. The dismantling operation will destroy the integrity of the support frame and reduce the reuse rate of the support frame. Summary of the invention

[0007] In order to solve the problems existing in the prior art, the present invention provides a connection node for connecting a support frame and a conversion beam. While having high connection strength, the support frame does not need to be damaged during dismantling, which can improve the reuse rate of the support frame and thus improve construction efficiency.

[0008] The technical solution to the problem solved by the present invention is to provide a connection node for connecting a support frame and a conversion beam, wherein the support frame includes a plurality of columns, and the connection node includes at least one clamping structure for connecting the columns and the conversion beam; the clamping structure includes at least one pressure plate, and the pressure plate includes a connecting piece connected to the conversion beam, and a fixing piece for applying pressure to the column to fix the column.

[0009] Furthermore, the connection node for connecting the support frame and the conversion beam provided by the present invention may also have the following characteristics: the connection piece is a welded piece welded to the conversion beam.

[0010] Furthermore, the connection node for connecting the support frame and the conversion beam provided by the present invention may also have the following characteristics: the column includes a column body and a base plate arranged at the bottom of the column body, and the fixing member includes a first pressure part, and the first pressure part applies a first pressure to the base plate.

[0011] Furthermore, the connection node for connecting the support frame and the conversion beam provided by the present invention may also have the following feature: the direction of the first pressure extends along the vertical direction.

[0012] Furthermore, the connection node for connecting the support frame and the conversion beam provided by the present invention may also have the following characteristics: the fixing member also includes a second pressure part, the second pressure part applies a second pressure to the base plate, and the direction of the second pressure is different from the direction of the first pressure.

[0013] Furthermore, the connection node for connecting the support frame and the conversion beam provided by the present invention may also have the following feature: the direction of the second pressure extends along the horizontal direction.

[0014] Furthermore, the connection node for connecting the support frame and the conversion beam provided by the present invention may also have the following characteristics: the clamping structure includes two pressure plates, and the two pressure plates are respectively arranged on the two side edges of the cylindrical surface of the column, and they are connected by a connecting plate.

[0016] Furthermore, the connection node for connecting the support frame and the conversion beam provided by the present invention may also have the following feature: the connection plate is connected to the pressure plate by welding.

[0017] Furthermore, the connection node for connecting the support frame and the conversion beam provided by the present invention may also have the following characteristics: the column and the conversion beam are connected by two clamping structures, and the two clamping structures are respectively arranged on both sides of the column.

[0018] The beneficial effects of the present invention are: 1. Compared with the traditional connection between the support frame and the conversion beam through bolt connection, anchor connection, sliding / telescopic connection, modular (latch / clip) connection or plug-in (mortise and tenon connection), the connection node for connecting the support frame and the conversion beam provided in the present application fixes the column through the fixing part of the pressure plate. While ensuring that the support frame has better stability, this non-permanent connection protects the support frame from being damaged when it is dismantled, thereby improving its reuse rate.

[0019] 2. In this application, the clamping structure constructs a multi-dimensional pressure system, and the pressure in multiple directions works together to fix the column, ensuring the stability of the column in the vertical direction and the shear resistance in the horizontal direction, so that the support frame can withstand extremely high loads.

[0020] 3. In the present application, the clamping structure does not use bolts or rivets, but adopts the design of pressure plates and connecting plates, which has the advantages of convenient processing and exquisiteness. Moreover, when dealing with complex spatial structures, this lightweight design helps to reduce occupied space and control costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention provides a connection node for connecting a support frame and a conversion beam, and the specific structure is as follows: like Figures 1 to 3 As shown, a support system includes a support frame 1 and a conversion beam 2, the support frame 1 includes a plurality of columns 3, the column 3 includes a column body 31 and a bottom plate 32 arranged at the bottom of the column body 31, and a plurality of triangular reinforcing plates 33 for reinforcing the connection strength are arranged between the column body 31 and the bottom plate 32, and two triangular reinforcing plates 33 are arranged at the two side edges of the column surface of the column body 31 respectively. The present invention provides a connection node for connecting a support frame with a conversion beam, comprising at least one clamping structure 4 for connecting the column 3 and the conversion beam 2; the clamping structure 4 includes at least one pressing plate 41, the pressing plate 41 includes a connecting member 42 connected to the conversion beam 2, and a fixing member 43 for applying pressure to the column 3 to fix the column 3. Compared with the traditional connection method of the support frame 1 and the conversion beam 2, the clamping structure 4 has better connection strength, and its non-permanent connection means that the column 3 can be easily disassembled by releasing the pressure of the fixing member 43 without destroying the column foot of the column 3, thereby ensuring the integrity of the support frame 1 and enabling it to be reused.

[0026] The connecting member 42 is preferably a welded member welded to the conversion beam 2, and the welded member is further preferably a fillet weld. The welded connection can provide higher stability, and when the support frame 1 is removed, the support frame 1 and the conversion beam 2 can be separated by cutting the welded member. This removal method does not cause any damage to the support frame or the conversion beam itself, and can not only improve the reuse rate of the connection node used to connect the support frame and the conversion beam, but also has the advantage of simple operation.

[0027] like Figure 2 and Figure 3As shown, the fixing member 43 includes a first pressure portion 51, and the first pressure portion 51 applies a first pressure 61 to the bottom plate 32. The first pressure 61 extends in the vertical direction, which can ensure the close contact between the column 3 and the conversion beam 2. Further, the fixing member 43 also includes a second pressure portion 52, and the second pressure portion 52 applies a second pressure 62 to the bottom plate 32. The direction of the second pressure 62 is different from the first direction 61, and preferably extends in the horizontal direction. Since the first pressure 61 and the second pressure 62 apply pressure to the bottom plate 32 from different directions respectively, the fixing member 43 can form a multi-dimensional stable system when fixing the column 3, which not only increases the stability of the column 3 in the vertical direction, but also enhances its shear resistance in the horizontal direction.

[0028] As a further improvement of the above embodiment, Figure 3 As shown, the clamping structure 4 includes two pressing plates 41, and the two pressing plates 41 are respectively arranged on the two side edges of the cylindrical surface of the column 31, and they are connected by a connecting plate 44. Compared with the clamping structure 4 formed by a single pressing plate 41, the two pressing plates 41 can fix the column 3 more effectively, and due to the setting of the connecting plate 44, there is a tension 7 between the two pressing plates 41 and the tension 7 is evenly distributed between the two pressing plates 41 through the connecting plate 44, ensuring the stability of the clamping structure 4. Preferably, the two ends of the connecting plate 44 are respectively connected to the middle of the two pressing plates 41 to ensure that the connecting plate 44 is parallel to the cylindrical surface of the column 31, further improving the stability of the clamping structure 4. Preferably, in order to facilitate the disassembly and assembly of the clamping structure 4, as shown in FIG. Figure 2 As shown, the pressing plate 41 is arranged on a side of the triangular reinforcing plate 33 away from the center of the column 3 .

[0029] The connecting plate 44 is welded to the pressing plate 41 . The welding connection is achieved by melting the metal materials to fuse them together to form a continuous whole. Therefore, the pressing structure 4 can withstand greater tension, pressure and shear force and is suitable for high-load structures.

[0030] The material of the pressing plate 41 is preferably a steel plate, and the thickness is preferably greater than 10 mm, to ensure that it is not easily deformed or damaged when bearing a large load, and has the advantages of being delicate and easy to process.

[0031] The column 3 and the conversion beam 2 can be connected by two clamping structures 4 or four clamping structures 4. Preferably, the column 3 and the conversion beam 2 are connected by two clamping structures 4, and the two clamping structures 4 are respectively arranged on both sides of the column 3.

[0032] In some specific embodiments, it is only necessary to clamp the bottom plate 32 under the first pressure part 51 of the two pressure plates 41, and make the second pressure part 52 abut against the column 31, and the third pressure part 53 abut against the side of the triangular reinforcing plate 33 away from the center of the column, and then connect the connecting piece 42 with the corner weld of the conversion beam 2 to construct the clamping structure 4. After the two clamping structures 4 are constructed on both sides of the column 3, a connection node that can stably fix the column 3 and the conversion beam 2 is created; and when dismantling, it is only necessary to cut the connecting piece 42 to dismantle the clamping structure 4 and release the connection between the support frame 1 and the conversion beam 2. Using such a connection node to fix the support frame has the advantages of high stability, convenient disassembly and assembly, and high reuse rate, which can effectively improve construction efficiency.
