The restraining device comprises a pair of clamping pieces and a pair of restraining rods, wherein the clamping pieces are arranged in a split mode and fixedly clamped with the roof truss supporting column, and the restraining rods are arranged on the front sides and the rear sides of the two clamping pieces in a crossing mode. Connecting shafts are arranged on the front side and the rear side of each clamping piece, the two ends of each restraining rod are assembled with the corresponding connecting shafts in a sliding mode respectively, the outer sides of the restraining rods are limited through first bolt assemblies in threaded connection with the connecting shafts, and an area defined by the two clamping pieces and the two restraining rods forms a restraining frame fixed to a web member of a roof truss in a clamping mode. By the adoption of the restraining device, the roof truss and the roof truss supporting columns can be restrained into a whole, and therefore the overall anti-impact performance is effectively improved.

Description

Technical Field

[0001] The invention belongs to the technical field of roof trusses, and particularly relates to a constraint device for between a roof truss and a roof truss support column. Background Art

[0002] For the purpose of drainage, the roofs (canopies) of photovoltaic power generation greenhouses, factory canopies, etc. usually have a certain slope, and the roof trusses generally adopt trusses. At present, when installing a roof truss, the roof truss is usually directly lapped on the top of the roof truss support column (the intersection of the web members of the roof truss is supported and connected to the roof truss support column). The advantages of this installation method are: the installation and disassembly of the roof truss are simple, and the roof truss is heavy and will not easily slip off the roof truss support column, and the installation stability is guaranteed to a certain extent, which can meet the use requirements of most occasions.

[0003] However, the above non-rigid constraint installation form between the roof truss and the roof truss support column also has the following disadvantages: for a photovoltaic power generation greenhouse across a highway, etc., if the roof truss support column is accidentally hit by a vehicle, the impact force can only be borne by the hit roof truss support column, which greatly increases the safety risks of the fracture of the roof truss support column and the collapse of the roof truss. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a constraint device for between a roof truss and a roof truss support column, so as to constrain the roof truss and the roof truss support column into a whole, thereby improving the overall anti-impact performance.

[0006] Further, the constraint rod includes a round rod main body and connecting pieces arranged at both ends of the round rod main body, and connecting holes for slidably assembling with the corresponding connecting shafts are opened on the connecting pieces.

[0007] Further, the clamping member includes a skeleton and a hoop piece connected to the skeleton, and the hoop pieces of the two clamping members are fastened by a second bolt assembly after being closed to realize the clamping and fixing to the roof truss support column.

[0008] Further, upper hoop pieces and lower hoop pieces are arranged at intervals along the vertical direction on the skeleton, and the upper hoop pieces and the lower hoop pieces of the two clamping members are respectively paired.

[0009] Further, the upper hoop piece is fixedly connected with a hanging plate that overlaps with the top of the roof truss column.

[0010] Further, the connecting shaft is arranged on the front side and the rear side of the top of the framework.

[0011] Further, both the upper hoop piece and the lower hoop piece are fixedly welded to the corresponding framework.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become more clearly defined. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0024] As Figures 1 to 8 shown, this embodiment provides a restraint device for between a roof truss and a roof truss support column, including a pair of clamping members 2 that are arranged in a split manner and clamped and fixed to the roof truss support column 1, and a pair of restraint rods 4 that are arranged across the front and rear sides of the two clamping members; connection shafts 7 are arranged on the front and rear sides of the clamping members, and the two ends of the restraint rod are respectively slidably assembled with the corresponding connection shafts, and are limited by a first bolt assembly 3 that is threadedly connected to the connection shafts. The area surrounded by the two clamping members and the two restraint rods forms a restraint frame that is clamped and fixed to the web member 6 of the roof truss 5.

[0025] In this embodiment, a pair of clamping members are respectively arranged on the left and right sides. The left end of the restraint rod at the rear side is assembled with the connection shaft at the rear side of the left clamping member, and the right end of the restraint rod at the rear side is assembled with the connection shaft at the rear side of the right clamping member; the left end of the restraint rod at the front side is assembled with the connection shaft at the front side of the left clamping member, and the right end of the restraint rod at the front side is assembled with the connection shaft at the front side of the right clamping member.

[0026] In this embodiment, the restraint rod includes a round rod main body 401 and connection pieces 402 arranged at both ends of the round rod main body. Connection holes 403 for slidably assembling with the corresponding connection shafts are formed in the connection pieces.

[0027] In this embodiment, the clamping member includes a framework 201 and hoop pieces connected to the framework. The connection shafts are arranged on the front and rear sides of the top of the framework. After the hoop pieces of the two clamping members are closed, they are fastened by a second bolt assembly 9 to achieve clamping and fixing with the roof truss support column. Preferably, to improve the reliability of the clamping and fixing of the clamping member with the roof truss support column, upper hoop pieces 202 and lower hoop pieces 203 are arranged at intervals in the vertical direction on the framework. The upper hoop pieces and the lower hoop pieces are both welded and fixed to the corresponding frameworks, and the upper hoop pieces and the lower hoop pieces of the two clamping members are paired respectively. Further, a hanging plate 8 that overlaps with the top of the roof truss support column is fixedly connected to the upper hoop piece; when installing the clamping member, the hanging plate overlaps with the top of the roof truss support column, which can provide vertical restraint for the clamping member.

[0028] During application, first clamp and fix the clamping member to the roof truss column. Subsequently, install the restraint rods on the front and rear sides so that the web members of the roof truss are within the restraint frame. Then, slide the restraint rods along the connecting shaft to adjust the distance between the two restraint rods. Finally, tighten the first bolt assembly on the outside to clamp and fix the web members of the roof truss with the restraint rods. In this way, the roof truss column and the roof truss (the web members of the roof truss) can be constrained into one body, and further, the entire support system (all roof truss columns) can jointly bear the impact force, thereby effectively improving the overall impact resistance performance.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than 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 by the scope of the claims of the present invention.
