Description

Technical Field

[0001] This utility model belongs to the field of roof truss technology, specifically relating to a constraint device for the relationship between a roof truss and its support columns. Background Technology

[0002] For drainage purposes, the roofs of photovoltaic power generation greenhouses and factory sheds typically have a certain slope, and the roof trusses are generally used. Currently, when installing roof trusses, they are usually directly attached to the top of the roof truss supports (the junction of the roof truss web members is connected to the roof truss support). The advantages of this installation method are: the roof trusses are easy to assemble and disassemble, and because the roof trusses are relatively heavy, they will not easily slip off the roof truss supports, ensuring a certain degree of stability and meeting the usage requirements of most situations.

[0003] However, the non-rigid constraint installation method between the roof truss and the roof truss support also has the following drawbacks: For photovoltaic power generation greenhouses spanning highways, if the roof truss support is accidentally hit by a vehicle, the impact force can only be borne by the roof truss support that is hit, which greatly increases the safety risk of roof truss support breakage and roof truss collapse. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a constraint device for the roof truss and the roof truss support, so as to constrain the roof truss and the roof truss support into a whole, thereby improving the overall impact resistance performance.

[0005] This utility model solves the above problems through the following technical means: a constraint device for the relationship between a roof truss and a roof truss support, comprising a pair of clamping members that are split apart and clamped and fixed to the roof truss support, and a pair of constraint rods that are arranged across the front and rear sides of the two clamping members; each clamping member has a connecting shaft on its front and rear sides, and the two ends of the constraint rods are slidably assembled with the corresponding connecting shafts, and are limited on the outside by a first bolt assembly that is threaded to the connecting shaft; the area enclosed by the two clamping members and the two constraint rods constitutes a constraint frame that clamps and fixes to the web members of the roof truss.

[0006] Furthermore, the constraint rod includes a round rod body and connecting pieces disposed at both ends of the round rod body, wherein the connecting pieces are provided with connecting holes for sliding assembly with corresponding connecting shafts.

[0007] Furthermore, the clamping member includes a frame and a clamping plate connected to the frame. After the clamping plates of the two clamping members are closed, they are fastened by the second bolt assembly to achieve a tight clamping and fixing with the roof truss support.

[0008] Furthermore, the frame is provided with upper and lower clamping plates at vertical intervals, and the upper and lower clamping plates of the two clamping members are paired respectively.

[0009] Furthermore, the upper clamp is fixedly connected to a hanging plate that overlaps with the top of the roof truss support.

[0010] Furthermore, the connecting shaft is disposed on the front and rear sides of the top of the skeleton.

[0011] Furthermore, both the upper and lower clamping plates are welded and fixed to the corresponding skeleton.

[0012] The beneficial effects of this utility model are:

[0013] This utility model discloses a constraint device for connecting a roof truss to its supports.

[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 clearer and more apparent. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0024] like Figures 1 to 8 As shown, this embodiment provides a constraint device for the relationship between a roof truss and a roof truss support, including a pair of clamping members 2 that are split apart and clamped and fixed to the roof truss support 1, and a pair of constraint rods 4 that are arranged across the front and rear sides of the two clamping members; each clamping member has a connecting shaft 7 on its front and rear sides, and the two ends of the constraint rods are slidably assembled with the corresponding connecting shafts, and are limited on the outside by a first bolt assembly 3 that is threaded to the connecting shaft. The area enclosed by the two clamping members and the two constraint rods constitutes a constraint frame that clamps and fixes to the web members 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 constraint rod on the rear side is assembled with the connecting shaft on the rear side of the left clamping member, and the right end of the constraint rod on the rear side is assembled with the connecting shaft on the rear side of the right clamping member. The left end of the constraint rod on the front side is assembled with the connecting shaft on the front side of the left clamping member, and the right end of the constraint rod on the front side is assembled with the connecting shaft on the front side of the right clamping member.

[0026] In this embodiment, the constraint rod includes a round rod body 401 and connecting pieces 402 disposed at both ends of the round rod body. The connecting pieces are provided with connecting holes 403 that are slidably assembled with the corresponding connecting shafts.

[0027] In this embodiment, the clamping member includes a frame 201 and clamping plates connected to the frame. The connecting shaft is located on the front and rear sides of the top of the frame. After the clamping plates of the two clamping members are closed, they are fastened by the second bolt assembly 9 to achieve a tight clamping and fixing with the roof truss support. Preferably, to improve the reliability of the clamping member's tight clamping and fixing with the roof truss support, upper clamping plates 202 and lower clamping plates 203 are arranged vertically at intervals on the frame. The upper clamping plates and lower clamping plates are welded and fixed to the corresponding frames, and the upper clamping plates and lower clamping plates of the two clamping members are paired. Furthermore, the upper clamping plate is fixedly connected to a hanging plate 8 that overlaps with the top of the roof truss support; when the clamping member is installed, the hanging plate overlaps with the top of the roof truss support, which can provide vertical constraint for the clamping member.

[0028] In application, first, clamp the clamping device to the roof truss column, then install the constraint rods on the front and rear sides so that the web members of the roof truss are within the constraint frame. Next, slide the constraint rods along the connecting shaft and adjust the distance between the two constraint rods. Finally, tighten the first bolt assembly on the outside to clamp and fix the web members of the roof truss with the constraint rods. In this way, the roof truss column and the roof truss (roof truss web members) are constrained into one unit, so that the entire support system (all roof truss columns) can share 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 this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
