[0028] With the rapid development of super high-rise buildings, the demand for technological innovation in the construction industry is increasing. As a model of on-site industrialized construction of super high-rise buildings, the application of top mold is becoming more and more widespread.

[0029] At present, the I-beam connected below the top mold construction integrated platform is generally connected by welding or bolted. However, the welding connection has the problems of long construction operation time, poor welding condition, high safety risk, and will produce a large amount of waste gas to pollute the environment; the bolted connection needs to open a large number of connecting holes on the profiled steel, which will reduce the stress performance of the component. Moreover, the two connection methods will result in that the component has weak general turnover and cannot adapt to the installation, disassembly and moving position requirements under different working conditions.

[0030] In view of the above problems, the embodiments of the present application provide a clamping groove type connection structure, which can be applied to detachable connection of the truss lower chord and the I-beam, and can realize the position adjustment of the connection between the truss lower chord and the clamping groove type connection structure, and the position adjustment of the connection between the upper flange of the I-beam and the clamping groove type connection structure, so as to ensure that the clamping groove type connection structure has strong general turnover and can adapt to the installation, disassembly and moving position requirements under different working conditions, and has wide application range.

[0031] To solve the above problems, the embodiment of the present application provides a clamping groove type connecting structure which can be applied to detachably connect the lower chord of a truss and an I-shaped beam. The clamping groove type connecting structure can effectively transfer the load of the lower hanging I-shaped beam to the truss, and does not need to be welded on site and does not need to open a large number of connecting holes on the truss and the I-shaped beam, thereby improving the work efficiency of connecting the lower chord of the truss and the I-shaped beam, reducing the safety risk, reducing waste gas pollution, and improving the stress performance of the component. Moreover, the clamping groove type connecting structure can be conveniently moved according to the needs on site to realize the adjustment of the clamping position of the upper clamping groove on the lower chord of the truss and the adjustment of the clamping position of the lower clamping groove on the lower hanging I-shaped beam, so that the different installation accuracy position requirements of the lower hanging I-shaped beam on the truss structure can be realized. The clamping groove type connecting structure can effectively adapt to the construction error on site to meet the needs of different working conditions. The clamping groove type connecting structure is simple to disassemble and assemble, can be used repeatedly, and effectively reduces the construction cost, thereby supporting different use scenarios of the truss hanging I-shaped beam and having a wide range of applications.

[0032] The following will be described in detail in combination with specific embodiments. It should be noted that the sequence numbers of the following embodiments do not limit the preferred order of the embodiments.

[0033] Please refer to Figures 1 to 3 , Figure 1 is a front view structural schematic diagram of the clamping groove type connecting structure provided by the embodiment of the present application, Figure 2 is a front view structural schematic diagram of the clamping groove type connecting structure in use provided by the embodiment of the present application, Figure 3 is a side view structural schematic diagram of the clamping groove type connecting structure in use provided by the embodiment of the present application. As Figures 1 to 3 shown, the clamping groove type connecting structure is used to detachably connect the lower hanging beam 100 and the lower chord of the truss 200, wherein the lower hanging beam 100 has an upper flange 101 and can be specifically an I-shaped beam, that is, an I-beam or a H-beam.

[0034] Specifically, the clamping groove type connecting structure can include a lower clamping groove base 2, a first upper connecting plate 1A and a second upper connecting plate 1B. Wherein the lower clamping groove base 2 has opposite first and second sides (that is, Figure 1 the upper side and the lower side of the lower clamping groove base 2), the first side of the lower clamping groove base 2 is provided with an upper sliding groove 21, and the second side of the lower clamping groove base 2 is provided with a lower clamping groove 22. And the first upper connecting plate 1A and the second upper connecting plate 1B are respectively connected to the first side wall surface 21A and the second side wall surface 21B (that is, Figure 1The first transverse upper clamping groove 3A is formed between the first upper connecting plate 1A and the bottom wall surface 21C of the upper chute 21, the second transverse upper clamping groove 3B is formed between the second upper connecting plate 1B and the bottom wall surface 21C of the upper chute 21, and the first transverse upper clamping groove 3A, the second transverse upper clamping groove 3B and the middle upper clamping groove 3C are arranged in sequence.

[0035] In the embodiment, the upper clamping groove 3 of the clamping groove type connecting structure is used for clamping the lower chord of the truss 200, and the clamping position of the upper clamping groove 3 on the lower chord of the truss 200 is adjustable. Specifically, after the upper clamping groove 3 is clamped on the lower chord of the truss 200, the upper clamping groove 3 can move along the length direction of the lower chord of the truss 200, so that the position of the connection between the lower chord of the truss 200 and the clamping groove type connecting structure is adjustable. The lower clamping groove 22 of the clamping groove type connecting structure is used for clamping the upper flange 101 of the lower hanging beam 100, and the clamping position of the lower clamping groove 22 on the upper flange 101 of the lower hanging beam 100 is adjustable. Specifically, after the lower clamping groove 22 is clamped on the upper flange 101 of the lower hanging beam 100, the lower clamping groove 22 can move along the length direction of the upper flange 101 of the lower hanging beam 100, so that the position of the connection between the lower hanging beam 100 and the clamping groove type connecting structure is adjustable.

[0036] In addition, in specific implementation, the shapes of the upper chute 21, the first upper connecting plate 1A and the second upper connecting plate 1B can be designed to make the shape of the upper clamping groove 3 formed by the three match the shape of the lower chord of the truss 200, and the shape of the lower clamping groove 22 can be designed to make the shape of the lower clamping groove 22 match the shape of the upper flange 101 of the lower hanging beam 100, so that the clamping groove type connecting structure can firmly connect the lower chord of the truss 200 and the upper flange 101 of the lower hanging beam 100.

[0037] In some examples, as shown in Figure 3 and Figure 5 The lower clamping groove 22 can be a T-shaped clamping groove.

[0038] In some embodiments, as shown in Figures 1 to 4 The first upper connecting plate 1A can be a detachable connecting plate 1A, which is detachably connected to the first side wall surface 21A of the upper chute 21. In addition, as shown in Figures 1 to 3 The second upper connecting plate 1B can also be a detachable connecting plate 11, which is detachably connected to the second side wall surface 21B of the upper chute 21; or, as shown in Figure 4 and Figure 5 The second connecting plate 1B can be a fixed connecting plate 12, which is fixedly connected to the second side wall surface 21B of the upper chute 21.

[0039] Specifically, in the above embodiment in which the first upper connecting plate 1A is a detachable connecting plate 1A and the second upper connecting plate 1B is a detachable connecting plate 11, as shown in FIG. Figure 2 As shown, the specific operation process of connecting the upper slot 3 of the above-mentioned slot-type connection structure to the lower chord of the truss 200 may include: when the detachable connecting plate 1A and the detachable connecting plate 11 are both in a disassembled state, that is, when neither is connected to the side wall surface of the upper slide groove 21, the bottom wall surface 21C of the upper slide groove 21 is close to the lower surface of the lower chord of the truss 200; then, the detachable connecting plate 1A is detachably connected to the left side surface 21A of the upper slide groove 21 above the left side of the lower chord of the truss 200, and the detachable connecting plate 11 is detachably connected to the right side wall surface 21B of the upper slide groove 21 above the right side of the lower chord of the truss 200, so that the inner wall surface of the upper slide groove 21 and the two detachable connecting plates 1A / 11 form an upper slot 3 that is connected to the lower chord of the truss 200, thereby realizing the assembly of the above-mentioned slot-type connection structure on the lower chord of the truss 200.

[0040] Specifically, in the above embodiment in which the first upper connecting plate 1A is a detachable connecting plate 1A and the second upper connecting plate 1B is a fixed connecting plate 12, as shown in FIG. Figure 4 As shown, the specific operation process of connecting the upper slot 3 of the above-mentioned slot-type connection structure to the lower chord of the truss 200 may include: when the detachable connecting plate 1A is in a disassembled state, that is, not connected to the side wall surface of the upper slide groove 21, the right side of the lower chord of the truss 200 is inserted into the second transverse upper slot 3B formed by the fixed connecting plate 12 and the inner wall surface of the upper slide groove 21, and the lower surface of the lower chord of the truss 200 is tightly against the bottom wall surface 21C of the upper slide groove 21; then, the detachable connecting plate 1A is detachably connected to the left side surface 21A of the upper slide groove 21 above the left side of the lower chord of the truss 200 to form a first transverse upper slot 3A connected to the left side of the lower chord of the truss 200, thereby forming an upper slot 3 connected to the lower chord of the truss 200 formed by the inner wall surface of the upper slide groove 21, the detachable connecting plate 1A and the fixed connecting plate 12, thereby realizing the assembly of the above-mentioned slot-type connection structure on the lower chord of the truss 200.

[0041] Furthermore, it can be understood that, compared with the solution in which the first upper connecting plate 1A is a detachable connecting plate 1A and the second upper connecting plate 1B is a detachable connecting plate 11, the solution in which the first upper connecting plate 1A is a detachable connecting plate 1A and the second upper connecting plate 1B is a fixed connecting plate 12 can better adapt to the different operating conditions of the above-mentioned slot-type connection structure, and can simplify the above-mentioned slot-type connection structure, and help to more quickly assemble the above-mentioned slot-type connection structure on the lower chord of the truss 200 on site.

[0042] In some examples, the fixed connecting plate 12 may be connected to the second side surface 21B of the upper sliding groove 21 by welding.

[0043] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 4 , the detachable connecting plate 1A can be L-shaped, and can include a side plate and a bottom plate, wherein the side plate is detachably connected to the first side wall surface 21A of the upper chute 21, and the bottom plate is connected to the side plate, for example, perpendicularly.

[0044] In some examples, as shown in Figures 1 to 4 , the side plate of the detachable connecting plate 1A can be connected to the first side wall surface 21A of the upper chute 21 by bolts, for example, by bolt set 4A. Specifically, the bolt set 4A can pass through the side plate of the detachable connecting plate 1A and the first side wall of the upper chute 21 (i.e., the left side wall in Figure 1 ) in sequence and be fastened by nuts.

[0045] In some embodiments, as shown in Figure 1 and Figure 2 , the detachable connecting plate 11 can also be L-shaped, and can include a side plate and a bottom plate, wherein the side plate is detachably connected to the second side wall surface 21B of the upper chute 21, and the bottom plate is connected to the side plate, for example, perpendicularly.

[0046] In some examples, as shown in Figures 1 to 3 , the side plate of the detachable connecting plate 11 can be connected to the second side wall surface 21B of the upper chute 21 by bolts. For example, by bolt set 4B. Specifically, the bolt set 4B can pass through the side plate of the detachable connecting plate 11 and the second side wall of the upper chute 21 (i.e., the right side wall in Figure 1 ) in sequence and be fastened by nuts.

[0047] In the above embodiments, as shown in Figure 1 , Figure 2and Figure 4 As shown in the above, the above-mentioned clamping groove type connecting structure can further comprise a clamping structure 5, which is used to fix the clamping position of the upper clamping groove 3 on the lower chord of the truss 200.

[0048] Specifically, after the upper clamping groove 3 of the above-mentioned clamping groove type connecting structure is clamped on the lower chord of the truss 200, the above-mentioned clamping groove type connecting structure can be moved along the length direction of the lower chord of the truss 200, so as to adjust the clamping position of the upper clamping groove 3 of the above-mentioned clamping groove type connecting structure on the lower chord of the truss 200. And, after the clamping position of the upper clamping groove 3 of the above-mentioned clamping groove type connecting structure on the lower chord of the truss 200 is adjusted to a specified position, the lower chord of the truss 200 and the upper clamping groove 3 in the upper clamping groove 3 can be fixed by the above-mentioned clamping structure 5, so as to ensure that the relative position of the lower chord of the truss 200 and the upper clamping groove 3 will not change any more. In this way, it is ensured that the above-mentioned clamping groove type connecting structure can meet the different installation accuracy position requirements of the lower chord of the truss 200.

[0049] And, it needs to be noted that the specific structure and setting position of the clamping structure 5 are not limited in the embodiment, and the clamping structure 5 can only realize the function of fixing the clamping position of the upper clamping groove 3 on the lower chord of the truss 200.

[0050] In some embodiments, as shown in the above, Figure 1 , Figure 2 and Figure 4 the above-mentioned clamping structure 5 can comprise a clamping rod 51, which is used to pass through the inner wall surface (such as the bottom wall surface 21C) of the upper sliding groove 21 and extend into the upper sliding groove 21, and the length of the clamping rod 51 in the upper clamping groove 21 is adjustable. In this way, in the case that the upper clamping groove 3 is clamped on the lower chord of the truss 200, by adjusting the length of the clamping rod 51 extending into the upper clamping groove 3, the clamping rod 51 can clamp the lower chord of the truss 200 in the upper clamping groove 3, so as to fix the lower chord of the truss 200 in the upper clamping groove 3 and the upper clamping groove 3.

[0051] Specifically, the bottom wall surface 21C of the above-mentioned upper sliding groove 21 can be provided with a threaded hole penetrating the lower clamping groove base 2, and the clamping rod 51 can be connected with the threaded hole through threads, so as to realize that the clamping rod 51 can be screwed into or out of the threaded hole, so that the clamping rod 51 extends into or exits the above-mentioned upper clamping groove 3.

[0052] In some specific embodiments, as shown in the above, Figure 1 , Figure 2 and Figure 4 the above-mentioned clamping rod 51 can be a screw rod 51A specifically. Specifically, the above-mentioned clamping structure 5 can comprise a screw 50, and the above-mentioned clamping rod 51 can be the screw rod of the screw 50 specifically.

[0053] Specifically, the above-mentioned tightening structure 5 can further include a nut 52 and a blocking ring structure 53, the nut 52 and the blocking ring structure 53 are located outside the upper sliding groove 21, and the nut 52 is sleeved and fixed on the tightening rod 51, the blocking ring structure 53 has opposite first and second ends (i.e. Figure 1 、 Figure 2 、 Figure 4 the upper and lower ends of the blocking ring structure 53), the first end of the blocking ring structure 53 is connected with the lower clamping groove base 2, and the blocking ring structure 53 is used to limit the nut 52 between the second end of the blocking ring structure 53 and the lower clamping groove base 2, thereby preventing the problem of the tightening rod 51 of the above-mentioned tightening structure 5 from falling off the lower clamping groove base 2 after the connection between the tightening rod 51 and the lower clamping groove base 2 is loosened.

[0054] And it should be noted that the embodiment does not limit the specific structure and position of the blocking ring structure 53, and the blocking ring structure 53 cooperates with the nut 52 to prevent the tightening rod 51 of the above-mentioned tightening structure 5 from falling off the lower clamping groove base 2.

[0055] Specifically, the above-mentioned blocking ring structure 53 can be located directly below the lower clamping groove base 2 at the upper sliding groove 21, and can be connected with the lower clamping groove base 2 by welding.

[0056] In some specific embodiments, the number of the above-mentioned tightening structure 5 can be multiple, each of the multiple tightening structure 5 includes the above-mentioned tightening rod 51, and the tightening rod 51 included in each of the tightening structure 5 is used to pass through the bottom wall surface 21C of the upper sliding groove 21 and extend into the upper sliding groove 21, and the length of the tightening rod 51 included in each of the tightening structure 5 located in the upper clamping groove can be independently adjusted. In this way, when the upper clamping groove 3 is clamped to the lower chord of the truss 200, by adjusting the length of the tightening rod 51 included in each of the tightening structure 5 extending into the upper clamping groove 3, the tightening rod 51 included in each of the tightening structure 5 can be used to tighten different positions of the lower surface of the lower chord of the truss 200 in the upper clamping groove 3, thereby not only achieving more effective fixation of the lower chord of the truss 200 in the upper clamping groove 3 and the upper clamping groove 3, but also adapting to the installation levelness requirement of the lower chord of the truss 200.

[0057] In the above-mentioned embodiment, as shown in Figures 1 to 5 , the above-mentioned clamping groove type connection structure can further include a limiting structure 6, the limiting structure 6 is used to fix the clamping position of the lower clamping groove 22 on the upper flange 101 of the lower hanging beam 100.

[0058] Specifically, after the lower slot 22 of the slot-type connection structure is engaged with the upper flange 101 of the lower suspension beam 100, the slot-type connection structure can be moved along the length of the upper flange 101 of the lower suspension beam 100, thereby adjusting the engagement position of the lower slot 22 of the slot-type connection structure on the upper flange 101 of the lower suspension beam 100. Furthermore, after the engagement position of the lower slot 22 of the slot-type connection structure on the upper flange 101 of the lower suspension beam 100 is adjusted to a specified position, the upper flange 101 of the lower suspension beam 100 and the lower slot 22 can be fixed within the lower slot 22 by the limiting structure 6, thereby ensuring that the relative position of the upper flange 101 of the lower suspension beam 100 and the lower slot 22 no longer changes. In this way, the slot-type connection structure can meet the different precise installation position requirements of the upper flange 101 of the lower suspension beam 100.

[0059] Furthermore, it should be noted that this embodiment does not limit the specific structure and location of the limiting structure 4 , and the tightening structure 6 can simply fix the lower clamping groove 22 in the clamping position on the upper flange 101 of the lower hanging beam 100 .

[0060] In some embodiments, as Figures 1 to 5 As shown, the above-mentioned limiting structure 6 may include a bolt and nut structure 61. The bolts of the bolt and nut structure 61 (for example, GB5783 bolts) pass through the first side wall of the lower retaining groove 22, the lower hanging beam 100, and the second side wall of the lower retaining groove 22 in sequence, and are fastened together by nuts (for example, GB6170 nuts) of the bolt and nut structure 61. The first side wall and the second side wall of the lower retaining groove 22 are the side walls on opposite sides of the lower hanging beam 100 located in the lower retaining groove 22.

[0061] Specifically, if Figure 6 As shown, the above-mentioned lower hanging beam 100 (for example, the web of the above-mentioned lower hanging beam 100) can be provided with a positioning hole 100A for the bolt of the bolt and nut structure 61 to pass through, and the inner wall surface (for example, the side wall surface) of the above-mentioned lower slot 22 can be provided with a light hole 23, and the light hole 23 is used to expose the positioning hole 100A of the lower hanging beam 100 in the lower slot 22, so that the above-mentioned bolt and nut structure 61 connects the positioning hole 100A of the lower hanging beam 100 in the lower slot 22 with the light hole 23 on the inner wall surface of the lower slot 22, thereby preventing the lower hanging beam 100 from moving relative to the lower slot 22.

[0062] In other embodiments, the above-mentioned limiting structure 6 may include a tightening screw, which is used to pass through the inner wall of the lower slot 22 and extend into the lower slot 22 to enable the tightening screw to tightly press the lower hanging beam 100 in the lower slot 22.

[0063] Specifically, the inner wall surface (such as the side wall surface) of the lower clamping groove 22 can be provided with a threaded hole for the penetration of the jacking screw, and the threaded hole is used to expose the lower hanging beam 100 in the lower clamping groove 22, so that the jacking screw is connected with the threaded hole through the threaded connection, penetrates through the threaded hole, and abuts against the lower hanging beam 100 in the lower clamping groove 22, thereby preventing the lower hanging beam 100 from moving relative to the lower clamping groove 22.
