Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to a windproof lifting movable clamp for a roof panel, a movable clamp assembly and a roof panel assembly. Background Art

[0002] There is a roof structure of a large building that includes a plurality of roof panels arranged in succession. The edges of the roof panels on both sides have upturned ribs. The upturned ribs of adjacent roof panels are connected to each other to form a plate rib and two upright locking edges are sequentially buckled on the T-code of the bracket system. The clamps clamp the plate ribs and the T-code, thereby fixing the plurality of roof panels to the bracket system. In addition, a crossbeam is arranged to be connected to two adjacent clamps, and a press is arranged at the bottom of the crossbeam. The press restricts the roof panel from above, thereby preventing the roof panel from being lifted by wind.

[0003] The clamp includes two clips located on both sides, one of which has a connecting seat with a slot on the top, which is used to be fixedly connected to the crossbeam, the two clips are locked by bolts, and there is a gap between the lower parts of the two clips to form a plate rib clamping position for clamping the plate ribs.

[0004] The problem with the existing roof structure of this type is that the clamps impose excessive load on the plate ribs and keep them locked. Although this setting is helpful in dealing with extreme weather, it also keeps the plate ribs locked when the wind is low on a daily basis, inhibiting the expansion and sliding deformation required for the roof panel to cope with temperature, and can also cause permanent deformation or even permanent damage to the plate ribs. Summary of the invention

[0005] The object of the present invention is to provide a roof panel windproof lifting movable clamp, a movable clamp assembly and a roof panel assembly that can effectively cope with extreme weather, effectively maintain the deformation capacity of the roof panel in non-extreme weather and avoid applying excessive loads to the plate ribs for a long time.

[0006] The first purpose of the present invention provides a roof panel windproof lifting movable clamp comprising two clamping parts arranged opposite to each other, a plate rib clamping position is formed between the two clamping parts; a transition part is provided on the clamping parts, and the clamping parts respectively form a clamping part and a linkage part on the opposite sides of the transition part; the transition parts of the two clamping parts are rotatably connected at the axis, the two clamping parts are opposite to each other and the plate rib clamping position is formed between the two clamping parts; the two linkage parts are opposite to each other and a movable part accommodating position is formed between the two clamping parts, and the linkage part has a first mating surface facing the movable part accommodating position; the roof panel windproof lifting movable clamp can be transformed from a first state to a second state; when the roof panel windproof lifting movable clamp is in the first state, on the projection of the extension direction of the axis, the distance between the two first mating surfaces gradually decreases in the direction away from the axis; when the roof panel windproof lifting movable clamp is transformed from the first state to the second state, the two clamping parts rotate relative to each other, the two linkage parts move in the direction away from each other and the two clamping parts move in the direction close to each other.

[0007] It can be seen from the above scheme that the movable part accommodating position between the two linkage parts is used to place the movable part, and the movable part is used to be fixedly connected with the crossbeam recorded in the background technology. When the wind force is stronger, the crossbeam rises under the action of the wind force and the push of the deformed roof panel on the pressing tool. At this time, the movable part moves in the direction away from the axis and abuts against the matching surface to force the clamp to change from the first state to the second state, so that the two clamping parts move in the direction close to each other to strengthen the clamping of the plate ribs. Therefore, when the wind force is small or there is no wind, the movable part does not restrict the linkage part, the clamping part is in an active state, and the roof panel is in a relaxed state, so it has sufficient freedom of movement to cope with its own deformation under the influence of temperature and other external conditions, and avoids long-term excessive loads and causing permanent deformation or even permanent damage; and in extreme weather, the movable clamp can be changed to a tightened state to lock the plate ribs.

[0008] A further solution is that the linkage portion includes an outward extension section and an inward extension section, one end of the outward extension section is connected to the transition portion, and the inward extension section is bent and extended from the other end of the outward extension section; in the projection of the extension direction of the axis, the distance between the two outward extension sections gradually increases in the direction away from the axis; the first mating surface is located on the inward extension section.

[0009] As can be seen from the above, this arrangement creates a larger movable part accommodating space, which can accommodate larger and stronger movable parts; in addition, with the arrangement of the outward extension section, the linear movement of the movable part can also cause the clamping part to swing more significantly, thereby achieving a better fastening effect on the plate ribs.

[0010] A further solution is that the plate rib clamping position includes a curled edge accommodating space close to the axis and a straight edge accommodating space away from the axis; in the projection of the extension direction of the axis, the distance between the two clamping parts at the curled edge accommodating space is greater than the distance between the two clamping parts at the straight edge accommodating space.

[0011] As can be seen from the above, the straight edge accommodating space is used to accommodate the upturned straight edge portion on the roof panel rib, and the curled edge accommodating space is used to accommodate the curled top on the roof panel rib. This setting makes the rib clamping position better match the rib and more effectively prevent loosening.

[0012] A further solution is that the movable part accommodating position is continuous along the extension direction of the axis.

[0013] As can be seen from the above, since the opening of the movable part accommodating position on the side away from the axis is smaller, this arrangement is conducive to the installation of the movable part.

[0014] A further solution is that the windproof lifting movable clamp for the roof panel further comprises an abutment portion, which is bently connected to an end of the linkage portion away from the axis, and has an abutment surface facing away from the axis.

[0015] As can be seen from the above, the abutting portion is used to abut against the crossbeam. This arrangement can increase the distance between the abutting surfaces of the two clamping components, thereby allowing the crossbeam to be supported on the clamp more stably.

[0016] A further solution is that both adapter parts are provided with shaft hole seats, and the shaft hole seats are provided with shaft holes; the roof panel windproof lifting movable clamp also includes a rotating shaft, and the rotating shaft passes through the shaft holes on the two adapter parts.

[0017] As can be seen from the above, this arrangement effectively realizes the rotational connection between the two clamping components.

[0018] A further solution is that wind scale symbols are provided on the surface of the linkage portion, and at least two wind scale symbols are arranged in sequence along a direction away from the axis.

[0019] As can be seen from the above, under this setting, the staff can judge the current wind level by the current position of the movable part and the closest wind level scale symbol.

[0020] The second purpose of the present invention provides a movable clamp assembly, including a movable part and a roof panel windproof lifting movable clamp as described above; the movable part is arranged in a movable part accommodating position, and a second mating surface is respectively provided on the opposite sides of the movable part, and the second mating surface is matched with the first mating surface; when the movable part moves in a direction away from the axis, the movable part can force the roof panel windproof lifting movable clamp in the first state to change to the second state.

[0021] As can be seen from the above, when the wind is small or there is no wind, the movable parts do not restrict the linkage part, the clamping part is in an active state, and the roof panel is in a relaxed state, so it has sufficient freedom of movement to cope with its own deformation under the influence of temperature and other external conditions, and avoid long-term excessive loads causing permanent deformation or even permanent damage; in extreme weather, the movable clamp can be changed to a tightened state to lock the panel ribs.

[0022] A further solution is that, in the projection of the extension direction of the axis, the width of the movable part gradually decreases in the direction away from the axis.

[0023] As can be seen from the above, this arrangement is more conducive to converting the linear movement of the movable part into the rotation of the clamping part, and the linkage effect is better.

[0024] The roof panel assembly provided by the third purpose of the present invention includes a roof panel group, a movable clamp assembly, a crossbeam and a press, the roof panel group includes at least two roof panels, the edges of the roof panels have upturned ribs, and the upturned ribs of the two roof panels cooperate with each other to form a plate rib; the movable clamp assembly adopts the above-mentioned movable clamp assembly, and the plate rib is located in the plate rib clamping position; the movable part and the press are both connected to the crossbeam, and the press restricts the roof panel from above.

[0032] See also Figure 1 and Figure 2 The roof panel assembly includes a roof panel group, a movable clamp assembly, a cross beam 4 and a press 5. The roof panel group includes a plurality of roof panels 1. The opposite side edges of the roof panels 1 respectively have a first upturned rib edge 11 and a second upturned rib edge 12. The plurality of roof panels 1 are arranged in sequence. Between two adjacent roof panels 1, the second upturned rib edge 12 of the first roof panel 1 and the first upturned rib edge 11 of the second roof panel 1 are connected to each other to form a plate rib 10. The two movable clamp assemblies and the two presses 5 are fixedly arranged on the lower side of the cross beam 4, and the two presses 5 are located between the two movable clamp assemblies. The movable clamp assembly is used to clamp on the plate rib 10 to achieve the connection between the cross beam 4 and the roof panel group. The press 5 is located above the roof panel 1 to limit the deformation of the roof panel 1. The first upturned rib edge 11 and the second upturned rib edge 12 are both the upturned rib edges of the present invention.

[0033] Combination Figure 6Further, the first upturned rib edge 11 includes a first upturned straight edge portion 111 bent upwardly from the roof panel body and a first curled top portion 112 connected to the upper end of the first upturned straight edge portion 111, and the second upturned rib edge 12 includes a second upturned straight edge portion 121 bent upwardly from the roof panel body and a first curled top portion 122 connected to the upper end of the second upturned straight edge portion 121. When fixing the roof panel 1, the second curled top portion 122 of one roof panel 1 is first buckled on the T code (not shown in the figure) of the bracket system, and the first curled top portion 112 of the other roof panel 1 is then buckled on the second curled top portion 122. Due to the arc design of the curled top portion, the plate rib 10 has an enlarged top portion.

[0034] The movable fixture assembly includes: Figure 3 and Figure 4 The roof panel windproof lifting movable clamp 2 shown in the figure and Figure 5 The movable part 3 shown. See 3 and Figure 4 The roof panel windproof lifting movable clamp 2 includes two clamping components 21 arranged opposite to each other and a rotating shaft 29. The clamping component 21 includes a transfer portion 22, a clamping portion 23, a linkage portion 24 and an abutting portion 25.

[0035] The adapter 22 is used to be rotatably connected with the adapter 22 on another clamping component 21. A plurality of shaft hole seats 221 are provided on the adapter 22. The shaft hole seats 221 are provided with shaft holes 220 that penetrate along the axis 20. The plurality of shaft hole seats 221 are arranged in sequence with intervals along the extension direction of the axis 20, and a recess 222 that can accommodate the shaft hole seat 221 on another adapter 22 is formed between two adjacent shaft hole seats 221. When the two clamping components 21 are combined, the plurality of shaft hole seats 221 on the two adapters 22 are staggered and located in the recess 222 of the other adapter 22. The shaft holes 220 of the plurality of shaft hole seats 221 are concentric with each other, and the rotating shaft 29 passes through the plurality of shaft holes 220.

[0036] The clamping portion 23 and the linkage portion 24 are respectively located at opposite sides of the adapter portion 22, and the clamping portion 23 and the linkage portion 24 extend from the adapter portion 22 in directions opposite to each other. The abutment portion 25 is bent and connected to one end of the linkage portion 24 away from the axis 20 of the adapter portion, and has an abutment surface 251 opposite to the axis 20.

[0037] When the two clamping parts 21 are connected, a distance is formed between the two clamping parts 23 to form a plate rib clamping position 230, and a distance is formed between the two linkage parts 24 to form a movable part accommodating position 240. The plate rib clamping position 230 and the movable part accommodating position 240 are both connected along the extension direction of the axis 20.

[0038] Furthermore, since the plate rib 10 has a top with an increased size, in order to cooperate with the plate rib 10, the plate rib clamping position 230 includes a curling accommodating space 2310 close to the axis 20 and a straight edge accommodating space 2320 away from the axis 20; in the projection of the extension direction of the axis 20 (such as Figure 4 As shown), the distance between the two clamping portions 23 at the curling accommodating space 2310 is greater than the distance between the two clamping portions 23 at the straight edge accommodating space 2320. Further, the clamping portion 23 includes an arc extension section 231 close to the axis 20 and a straight extension section 232 away from the axis 20. The arc extension section 231 is located on one side of the curling accommodating space 2310, and the inner side of the arc extension section 231 is toward the concave arc surface of the curling accommodating space 2310 and the concave arc surface is recessed away from the curling accommodating space 2310. The straight extension section 232 is located on one side of the straight edge accommodating space 2320, and the inner side of the straight extension section 232 includes a plane facing the straight edge accommodating space 2320.

[0039] An opening 240a is formed between the two connecting parts 24 extending away from the adapter part 22. For the connecting parts 24 and the features thereon, Figure 4 The positive direction of the x-axis shown in the figure is the direction away from the axis 20 in the present invention, and the positive direction of the x-axis is the direction away from the axis 20 toward the opening 240a. Figure 4 As shown, the linkage portion 24 includes an outwardly extending section 241 and an inwardly extending section 242 . One end of the outwardly extending section 241 is connected to the adapter portion 22 , and the inwardly extending section 242 is bent and extended from the other end of the outwardly extending section 241 .

[0040] exist Figure 4 In the first state shown, in the projection of the extension direction of the axis 20, the distance between the two outward extension sections 241 gradually increases in the direction away from the axis 20, and the distance between the two inward extension sections 242 gradually decreases in the direction away from the axis 20 (positive direction of the x-axis). The inner side of the inward extension section 242 has a first mating surface 243 facing the movable member accommodation position 240. Similarly, in the projection of the extension direction of the axis 20, the distance between the two first mating surfaces 243 gradually decreases in the direction away from the axis 20. The first mating surface 243 of this embodiment is a plane. In other embodiments, the first mating surface may be an inner concave arc surface or an outer convex arc surface.

[0041] In addition, a wind level scale symbol 249 is provided on the end surface of the inward extension section 242 in the extension direction of the axis 20 , and three wind level scale symbols 249 are arranged in sequence along the direction away from the axis 20 .

[0042] See also Figure 1 , Figure 2 and Figure 5The movable part 3 includes a main body with a roughly trapezoidal cross-sectional profile and a screw 39 fixedly arranged on the top of the main body. The cross beam 4 is provided with a plurality of elongated through holes 40 penetrating along the height direction. The screw 39 passes through the through holes 40 from bottom to top and then is fitted with a pad 41 and locked by a locking nut 42, thereby achieving the fixation between the movable part 3 and the cross beam 4.

[0043] The second mating surfaces 301 are arranged on both sides of the width of the main body of the movable part 3, and the extension direction of the second mating surfaces 301 is inclined to the height direction of the main body of the movable part 3 so that the distance between the two second mating surfaces 301 gradually decreases along the height direction of the main body of the movable part 3. In the projection of the extension direction of the axis 20, the width of the movable part 3 gradually decreases in the direction away from the axis 20. In addition, in order to reduce the weight, the main body of the movable part 3 is set to be hollow.

[0044] Recombination Figures 4 to 6 The movable part accommodating position 240 is used to accommodate the movable part 3. After the roof panel windproof lifting movable clamp 2 has been clamped on the plate rib 10, the movable part 3 is inserted into the movable part accommodating position 240 along the axial direction of the axis 20. At this time, the first mating surface 243 is opposite to the second mating surface 301.

[0045] Combination Figure 2 , Figure 6 and Figure 7 , Figure 2 and Figure 6 The roof panel windproof lifting movable clamp 2 shown in FIG. is in the first state. Figure 7 The roof panel windproof lifting movable clamp 2 shown in the figure is in the second state. When the wind force is stronger, the cross beam 4 rises under the action of the wind force and the push of the pressing tool 5 by the roof panel 1 deformed by the wind, and the movable part 3 fixedly connected to the cross beam 4 also moves upward. Since the two first mating surfaces 243 of the roof panel windproof lifting movable clamp 2 in the first state are inclined to each other and the two second mating surfaces 301 are also inclined to each other, when the movable part 3 rises, the first mating surface 243 abuts against the second mating surface 301 and forces the linkage part 24 to swing outward, that is, the two linkage parts 24 move away from each other, and at the same time, the two clamping parts 23 move toward each other to strengthen the clamping of the plate rib 10.

[0046] Therefore, when the wind is small or there is no wind, the movable part 3 does not restrict the linkage part 24, the clamping part 23 is in an active state, and the roof panel 1 is in a relaxed state and has sufficient freedom of movement to cope with its own deformation under the influence of temperature and other external conditions, and to avoid permanent deformation or even permanent damage caused by long-term excessive load; in extreme weather, the movable clamp can be changed to a tightened state to lock the plate rib 10.

[0047] In addition, the comparison Figure 5 and Figure 6When the movable part 3 is in different positions, the movable part 3 matches different wind level scale symbols 249 , so the staff can judge the current wind level through the current position of the movable part 3 and the closest wind level scale symbol 249 .

[0048] In addition, if Figure 6 As shown, even if the roof panel windproof lifting movable clamp 2 is in the second state, in the projection of the extension direction of the axis 20, the distance between the two first matching surfaces 243 gradually decreases in the direction away from the axis 20. This arrangement prevents the movable part 3 from escaping from the movable part accommodation position 240 and causing an accident.

[0049] In addition, if Figure 2 and Figure 5 As shown, when the wind is small or there is no wind, the beam 4 is supported on the abutment surface 251 .

[0050] In other embodiments, the width of the movable part is uniform in the direction away from the axis. Since the inclined setting of the first matching surface has a guiding effect, even if the movable part is not provided with an inclined second matching surface, the rising movable part can force the clamping part to swing.

[0051] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
