[0002] Nowadays, with the emergence of large-span buildings such as large exhibition halls and conference halls, the application of trusses has become common, especially some large-span heavy trusses have also become popular. During the construction of the trusses, the sliding conversion of the trusses has become the focus and difficulty of truss construction, especially in large-span or heavy trusses. This problem is more prominent.
[0003] In order to carry out sliding construction of a large-span truss roof structure, a hydraulic jack is required to provide horizontal force, and there is a connecting device between the two. Traditional connecting devices often include ear plates and sliders. The ear plates are used to connect the hydraulic jacks to the components, and the sliders are located between the components to be pushed and the slide rails in the height direction. They are mainly responsible for supporting the truss structure to facilitate forward movement in the track. However, the shape of the slider is often selected as a rectangular parallelepiped. When the sliding track is uneven, it is easy to "get stuck" and "bite the track", which affects the speed of truss construction and creates safety hazards. Utility Model Content

[0014] In an optional implementation, both of the two second transition surfaces are smooth arc surfaces.
[0015] Beneficial effect: By setting the second transition surface as a smooth arc surface, the resistance encountered by the sliding front end side of the slider during movement can be further reduced.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0045] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0046] Combine the following Figures 1 to 10 , describing an embodiment of the utility model.
[0047] According to an embodiment of the present utility model, on the one hand, a sliding device is provided, such as Figures 1 to 6 As shown, the sliding device 1 is used to connect and fix the pushing device and the structure to be pushed 2 of the truss, and the sliding device 1 is used to drive the structure to be pushed 2 to slide along the guide of the slide rail 31 under the action of the pushing device. The sliding device 1 includes a slider 11, the slider 11 is fixedly installed at the bottom of the structure to be pushed 2, and the slider 11 is used to slide along the guide of the slide rail 31 in the slide rail 31. The sliding front end of the slider 11 is provided with an avoidance structure group, and the avoidance structure group is used to avoid the bottom wall of the slide rail 31 and / or the side wall of the slide rail 31 during the sliding of the slider 11.
[0048] In this way, by providing the sliding front end of the slider 11 with an avoidance structure group for avoiding the bottom wall of the slide rail 31 and / or the side wall of the slide rail 31, avoidance space is provided at the bottom of the slider 11 and / or the side of the slider 11 when the slider 11 slides. When the slider 11 is uneven, the phenomenon of "stuck rail" and "gnawing rail" is avoided, thereby ensuring stable sliding of the truss.
[0049] In one embodiment, Figure 5As shown, the avoidance structure group includes a first transition surface 111 arranged on the bottom wall of the sliding front end of the sliding block 11, and the distance between the first transition surface 111 and the ground gradually increases in the direction in which the sliding front end moves away from the sliding rear end.
[0050] In this way, by setting the first transition surface 111 and gradually increasing the distance between the first transition surface 111 and the ground in the direction where the front end of the slide moves away from the rear end of the slide, a bottom avoidance space is formed, thereby reducing the resistance encountered by the bottom of the front end of the slide during the movement of the slider 11, avoiding the phenomenon of "stuck rail" and "gnawed rail" by the bottom of the slide rail 31, and thus avoiding safety accidents caused by the phenomenon of "stuck rail" and "gnawed rail".
[0051] It can be explained that the size of the first transition surface 111 is not limited, and it only needs to be polished smooth. Figure 5 As shown, the first transition surface 111 is Figure 5 The size of the inner horizontal projection is preferably 100 mm. The first transition surface 111 is Figure 5 The inner vertical projection dimension is preferably 10 mm.
[0052] In one embodiment, Figure 5 As shown, the bottom wall surface of the sliding front end of the sliding block 11 further includes a sliding surface 112 , and the sliding surface 112 is connected to the first transition surface 111 , and the connection is tangent to each other.
[0053] In this way, by arranging the sliding surface 112 and the first transition surface 111 to be tangent to each other at their connection points, the resistance encountered by the bottom of the sliding front end of the slider 11 during its movement can be further reduced.
[0054] In one embodiment, Figure 6 As shown, the avoidance structure group includes two second transition surfaces 113 respectively arranged on the wall surfaces of both sides of the sliding front end of the sliding block 11, and the distance between the two second transition surfaces 113 gradually decreases in the direction in which the sliding front end moves away from the sliding rear end.
[0055] In this way, by setting two second transition surfaces 113 and gradually reducing the distance between the two second transition surfaces 113 in the direction where the front end of the slide moves away from the rear end of the slide, the resistance encountered by the side of the front end of the slide of the slider 11 during movement is reduced, thereby avoiding the phenomenon of "stuck rail" and "gnawed rail" by the side of the slide rail 31 on the slider 11, thereby avoiding safety accidents caused by the phenomenon of "stuck rail" and "gnawed rail".
[0056] It can be explained that there is no limitation on the length of the second transition surface 113, and it only needs to be polished to be smooth. Figure 6 As shown, any second transition surface 113 is Figure 6 The size of the inner horizontal projection is preferably 100 mm. Figure 6 The inner vertical projection dimension is preferably 10 mm.
[0057] It can be explained that there is no specific limitation on the structure of the second transition surface 113. As one embodiment, the two second transition surfaces 113 are both smooth arc surfaces.
[0058] In this way, by setting the second transition surface 113 as a smooth arc surface, the difficulty of the front end side of the slider 11 sliding through obstacles during movement is reduced, and the slider 11 can use the curvature of its sliding front end to pass obstacles when the side of the slide rail 31 is uneven.
[0059] In one embodiment, Figures 1 to 4 As shown, the sliding device 1 also includes a connecting assembly, which includes at least a connecting plate body 12 and an ear plate 13. The connecting plate body 12 is fixedly connected to one of the side plates of the structure to be pushed 2, and the ear plate 13 is fixedly installed on the side of the connecting plate body 12 away from the structure to be pushed 2.
[0060] In one embodiment, Figure 1 As shown, at least two ear plates 13 are provided, and at least two ear plates 13 are arranged at intervals.
[0061] In this way, by setting the number of ear plates 13 to at least two, compared with the scenario of using only one ear plate 13, the force on the ear plate 13 can be dispersed, the phenomenon of force concentration on the ear plate 13 can be improved, and the phenomenon of affecting the transmission efficiency between the hydraulic jack and the structure 2 to be pushed when the ear plate 13 is deformed can be avoided.
[0062] It can be explained that the ear plate 13 is selected to be carbon structural steel, such as Q355B carbon structural steel, and the ear plate 13 is welded to the connecting plate body 12, such as a double-sided fillet weld connection.
[0063] Likewise, there is no specific limitation on the thickness of the ear plate 13, such as 20 mm.
[0064] In one embodiment, Figure 2 As shown, the connection assembly further includes a reinforcing member 14 , which is mounted on one of the side plates of the structure 2 to be moved, and is fixedly connected to the connection plate body 12 .
[0065] In this way, the connection plate body 12 can be reinforced by the arrangement of the reinforcement member 14, thereby improving the phenomenon that the connection plate body 12 is damaged when subjected to concentrated force.
[0066] It can be explained that the side plate used for installing the reinforcement member 14 in the structure to be pushed 2 is the support stiffening plate 21 .
[0067] It can be explained that there is no specific limitation on the type of the reinforcement member 14. As one embodiment, the reinforcement member 14 is selected as a rib, such as Figure 2 As shown, at this time, there are four reinforcement members 14 , which are divided into two groups, each group includes two reinforcement members 14 , and the two groups of reinforcement members 14 are respectively installed on both sides of the support stiffening plate 21 .
[0068] In one embodiment, the connection assembly further includes a positioning member 15 , which is disposed on a side of the connection plate body 12 away from the structure to be moved 2 , and is used to fix the slider 11 to the connection plate body 12 .
[0069] The arrangement is as follows: by setting the positioning member 15 on the side of the connecting plate body 12 away from the structure to be pushed 2, and using the positioning member 15 to fix the slider 11 and the connecting plate body 12, the structure to be pushed 2 and the slide rail 31 are fixed, preventing the structure to be pushed 2 and the slider 31 from being misaligned during the sliding process due to the unevenness of the slide rail 31, thereby avoiding installation accidents.
[0070] It can be explained that the positioning member 15 is selected to be carbon structural steel, such as Q355B carbon structural steel, and the positioning member 15 is connected and fixed to the connecting plate body 12 and the slider 11 by welding, such as first-level full penetration welding.
[0071] Likewise, there is no specific limitation on the thickness of the positioning member 15, such as 30 mm.
[0072] In one embodiment, the positioning member 15 is a plate-shaped structure, one of the side walls of the positioning member 15 is fixedly connected to the connecting plate body 12 , and the bottom wall of the positioning member 15 is fixedly connected to the slider 11 .
[0073] According to an embodiment of the present utility model, on the other hand, a truss sliding system is provided, comprising the sliding device 1 mentioned in the above embodiment.
[0074] Such arrangement has the same effect as the sliding device 1 because the truss sliding system includes the sliding device 1, and thus will not be described in detail.
[0075] In one embodiment, Figure 1 and Figure 2 As shown, the truss sliding system includes a structure to be moved 2 and a sliding device 1. At this time, a support stiffening plate 21 is provided at the bottom of the structure to be moved 2, and the support stiffening plate 21 includes a mounting plate body 211 and a plurality of reinforcement plates 212. The two ends of the mounting plate body 211 arranged in the height direction are respectively connected and fixed to the bottom wall surface of the structure to be moved 2 and the top wall surface of the slider 11. The plurality of reinforcement plates 212 are evenly distributed on one or more side walls of the mounting plate body 211, and the plurality of reinforcement plates 212 are spaced apart around the outer circumference direction of the mounting plate body 211.
[0076] Further, as one implementation mode, Figures 7 to 10 As shown, there is one mounting plate 211 and two groups of reinforcing plates 212, the two groups of reinforcing plates 212 are respectively arranged on two side walls of the reinforcing plates 212 which are arranged opposite to each other, and the number of reinforcing plates 212 in each group is one, two or more, preferably three. If the number of reinforcing plates 212 in each group is two or more, at this time, any reinforcing plate in any group is arranged to be spaced apart from the reinforcing plates in the same group.
[0077] It can be explained that if Figure 7 As shown, the side plate used for installing the reinforcement member 14 in the structure to be moved 2 is the installation plate body 211 in the support stiffening plate 21 .
[0078] In one embodiment, Figure 8 and Fig. 9 As shown, the truss sliding system also includes a sliding rail 31, a sliding track beam 32 and a concrete column 4. At this time, a gap is left between the lower chord 22 of the truss and the concrete column 4 to form a sliding space, and the sliding rail 31 is installed on the top of the sliding track beam 32, and the sliding track beam 32 is passed through the top of the concrete column 4, and the structure 2 to be moved and the sliding rail 31 are set in the sliding space.
[0079] Furthermore, if Figures 8 to 10 As shown, the truss sliding system further includes a side block 33 , in which case the side block 33 is welded to the outside of the slide rail 31 , and the side block 33 is connected and fixed to the slide track beam 32 .
[0080] It should be noted that during installation, the sliding track beam 32 is fixed to the concrete column 4, and then the side block 33 is used to install the slide rail 31 on the top of the sliding track beam 32. Before the structure 2 to be moved needs to be moved, a support such as a jack is used to lift the lower chord 22 of the truss or the support stiffening plate 21, and then the reinforcement member 14, the connecting plate body 12 and the ear plate 13 are welded on the support stiffening plate 21 in sequence. At the same time, the slider 11 is set directly below the support stiffening plate 21, and then the structure 2 to be moved is dropped, and the support stiffening plate 21 is placed on the top of the slider 11, and then the positioning member 15 is welded to the slider 11 and the connecting plate body 12 respectively to complete the installation process. Then, a jacking device such as a hydraulic jacking device is used, and the jacking end of the hydraulic jacking device is fixed to the ear plate 13 through a pin shaft to transmit the horizontal sliding jacking force, and then the sliding of the structure 2 to be moved is completed. When it moves to the desired position, the sliding device 1 is removed.
[0081] Furthermore, when dismantling the sliding device 1, it is necessary to remove the reinforcing member 14, the positioning member 15, the connecting plate body 12, the ear plate 13 and the sliding block 11 from the support stiffening plate 21. The way to remove each component is, for example, cutting. Specifically, the reinforcing member 14 and the connecting plate body 12 are cut, and then the structure to be moved 2 is lifted up with a jack, and one or more components among the ear plate 13, the connecting plate body 12, the sliding block 11 and the positioning member 15 are acted on to extract the sliding block 11, and then the structure to be moved 2 is dropped.
[0082] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
