Description

Technical Field

[0001] The invention belongs to the technical field of roof truss construction equipment, and particularly relates to an anti-overturning temporary support device suitable for roof truss construction. Background Art

[0002] In the field of photovoltaic power generation greenhouses across expressways, considering vehicle passage, stability, etc., the greenhouse roof trusses are generally designed as trusses and have a relatively high height, while the width (longitudinal) of the greenhouse is relatively narrow. Therefore, the aspect ratio of the greenhouse is usually large.

[0003] During the hoisting construction process of the greenhouse roof truss, the assembled greenhouse roof truss needs to be hoisted and placed on the support columns. Before the greenhouse roof truss is stably connected to the support columns, due to the large aspect ratio of the greenhouse, the greenhouse roof truss is prone to lateral overturning. Therefore, a crane is required to stabilize the greenhouse roof truss, and the crane cannot be withdrawn, which to a certain extent affects the flexibility of crane use and increases the construction cost. Summary of the Invention

[0004] In view of this, the purpose of the invention is to provide an anti-overturning temporary support device suitable for roof truss construction, so as to realize the temporary auxiliary support of the roof truss after the roof truss is hoisted onto the support column and reduce the possibility of roof truss overturning.

[0005] The invention solves the above problems through the following technical means: an anti-overturning temporary support device suitable for roof truss construction, including a hoop and two sets of support rod groups fixedly arranged on the left and right sides of the hoop. The support rod group includes a lower support rod and an upper support rod. The bottom end of the lower support rod is hinged to the hoop, and the top end of the lower support rod is hinged to the bottom end of the upper support rod through a connecting shaft. The corresponding ends between the left and right connecting shafts are connected through an adjusting screw assembly.

[0006] Further, both ends of the connecting shaft are integrally provided with connecting blocks, and the corresponding end connecting blocks of the two connecting shafts are connected through an adjusting bolt assembly.

[0007] Further, the adjusting bolt assembly includes an adjusting screw and an adjusting nut. The adjusting screw passes through two corresponding connecting blocks, and the adjusting nut is threadedly connected to the end of the adjusting screw away from the nut.

[0008] Further, two legs are integrally provided at the bottom end of the upper support rod, and a first connecting sleeve for rotatably assembling with the connecting shaft is integrally provided at the bottom end of the leg.

[0009] Further, a second connecting sleeve for rotatably assembling with the connecting shaft is integrally provided at the top end of the lower support rod.

[0010] Further, a support plate is fixedly arranged on the hoop, a fixed sleeve is fixedly arranged on the support plate, and a hinge shaft rotatably assembled with the fixed sleeve is integrally arranged at the bottom end of the lower support rod.

[0011] Further, a support cross bar is arranged at the top end of the upper support rod.

[0012] Advantages of the present invention:

[0013] The anti-overturning temporary support device applicable to roof truss construction of the present invention includes a hoop and two sets of support rod groups fixedly arranged on the left and right sides of the hoop. The support rod groups include lower support rods and upper support rods. The bottom end of the lower support rod is hinged to the hoop, the top end of the lower support rod is hinged to the bottom end of the upper support rod through a connecting shaft, and the corresponding ends between the left and right connecting shafts are all connected through an adjusting screw assembly.

[0021] The present invention will be further described in detail below with reference to the drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more definite. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Such as Figures 1 to 6As shown in the figure, this embodiment provides an anti-overturning temporary support device applicable to roof truss construction, which includes a hoop 2 and two sets of support rod groups fixedly arranged on the left and right sides of the hoop. The support rod group includes a lower support rod 5 and an upper support rod 6; the bottom end of the lower support rod is hinged to the hoop. Specifically, a support plate 3 is fixedly arranged on the hoop, a fixed sleeve 4 is fixedly arranged on the support plate, and a hinge shaft 502 that is rotationally assembled with the fixed sleeve is integrally arranged at the bottom end of the lower support rod. In this embodiment, two fixed sleeves 4 are arranged at intervals, the lower support rod 5 is connected to the middle of the hinge shaft 502, and both ends of the hinge shaft are rotationally assembled with the two fixed sleeves respectively.

[0023] The top end of the lower support rod is hinged to the bottom end of the upper support rod through a connecting shaft 9. Specifically, two legs 601 are integrally arranged at the bottom end of the upper support rod, and a first connecting sleeve 602 that is rotationally assembled with the connecting shaft is integrally arranged at the bottom end of the leg; a second connecting sleeve 501 that is rotationally assembled with the connecting shaft is integrally arranged at the top end of the lower support rod; the second connecting sleeve is located between the two first connecting sleeves.

[0024] The corresponding ends of the left and right connecting shafts are all connected through an adjusting screw assembly. In this embodiment, connecting blocks 901 are integrally arranged at both ends of the connecting shaft, and the connecting blocks at the corresponding ends of the two connecting shafts are connected through an adjusting bolt assembly. Specifically, the connecting block at the front end of the left connecting shaft is connected to the connecting block at the front end of the right connecting shaft through an adjusting bolt assembly, and the connecting block at the rear end of the left connecting shaft is connected to the connecting block at the rear end of the right connecting shaft through an adjusting bolt assembly; the adjusting bolt assembly includes an adjusting screw 7 and an adjusting nut 8. The adjusting screw passes through the two corresponding connecting blocks, and the adjusting nut is threadedly connected to the end of the adjusting screw away from the nut. In this way, by rotating the adjusting nut, the entire support rod group can be lifted or lowered.

[0025] As a further improvement to the above technical solution, a support cross bar 603 is arranged at the top end of the upper support rod; so as to expand the support surface.

[0026] During use, install the hoop at the top of the support column 1. After the hoop is closed, it is tightly clamped to the support column. At the same time, make the support plate overlap on the top surface of the support column; then, rotate the adjusting nut to make the support rod group rise to support both sides of the roof truss 10, and perform temporary support on the roof truss, thereby ensuring the overall stability.

[0027] To sum up, after the roof truss is hoisted, this device is directly installed on the support column, and then the crane can be withdrawn, saving the crane shift and cost. At the same time, the space under the roof truss can be released without hindering other operations. After the purlins are installed at the top of the roof truss and the entire roof truss system is stable, this temporary support device can be disassembled and can be used for the next scenario.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
