Description

Technical Field

[0001] The utility model relates to the technical field of truss assembly, in particular to a docking guide structure for truss assembly. Background Art

[0002] A truss is a planar or spatial structure composed of straight rods, generally with triangular units. The truss rods mainly bear axial tension or pressure, thereby making full use of the strength of the material. When the span is large, it can save material, reduce deadweight and increase stiffness compared to solid beams.

[0003] Patent publication number CN117488647A discloses a construction method for composite beams with upper and lower steel trusses and webs, suitable for urban elevated highways. This method addresses the complex stress-bearing issues inherent in existing large-span truss beams, where the upper and lower chords and upper and lower decks are converted into prestressed concrete structures. The method includes an upper deck and a lower deck, connected by a number of evenly spaced webs. The upper portion of the upper deck is provided with a crash barrier, the upper side panel is provided with an upper chord for securing the upper portion of the webs, the lower panel is provided with a lower chord for securing the webs, and the lower panel is provided with piers, a cap is provided at the lower portion of the pier, and cast piles are provided at the lower portion of the cap. The method offers a stable structure, high construction efficiency, low steel consumption in the steel truss webs, material savings, a small construction footprint, and a small amount of material used in the buckle bracket, resulting in a fast construction schedule.

[0004] In the above technical solution, the composite beam is provided with an upper chord, a web and a lower chord.

DETAILED DESCRIPTION

[0034] The following will be combined with the specific embodiments of the present invention to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figure 1-4 As shown, the truss assembly docking guide structure of the present invention includes a bracket 1, a lower truss beam 2, two guide members 3 and an upper truss beam web assembly 4.

[0036] The bracket 1 is used to support the truss, which includes a lower truss beam 2 and an upper truss beam web assembly 4.

[0037] The lower truss beam 2 is fixedly mounted on the bracket 1 and has a mounting groove 201 formed on its top side.

[0038] The guide 3 is used to guide the docking of the lower truss 2 and the upper truss web assembly 4. The guide 3 is detachably fixed to the lower truss 2. The two guides 3 are symmetrically arranged about the center line of the lower truss 2, and the distance between the two guides 3 gradually increases along the direction from the bracket 1 to the lower truss 2.

[0039] The upper truss web assembly 4 is arranged between the two guide members 3, and one end thereof is fixedly arranged in the mounting groove 201; when assembling the truss, the lower truss 2 and the bracket 1 are installed first, and then the upper truss web assembly 4 is hoisted above the lower truss 2, and then the upper truss web assembly 4 is slowly moved downward, and the two guide members 3 are used to guide the upper truss web assembly 4 into the mounting groove 201, and finally the upper truss web assembly 4 and the lower truss 2 are fixedly connected. This method can quickly realize the docking of the upper truss web assembly 4 and the lower truss 2, and align the two, avoiding the problem of needing to reciprocate and adjust the upper truss web assembly 4, thereby greatly improving the assembly efficiency of the truss.

[0040] like Figure 2 and Figure 3 As shown, the guide member 3 includes a connecting plate 31, a wear-resistant plate 32, a reinforcement plate 33 and a wrapping portion 34. One end of the connecting plate 31 is detachably fixed to the outer side of the lower truss 2; the wear-resistant plate 32 is fixedly arranged on the side of the connecting plate 31 close to the center line of the lower truss 2. When assembling the truss, the wear-resistant plate 32 guides the upper truss web assembly 4, which is preferably made of materials such as hard rubber.

[0041] As a preferred embodiment, a plurality of connection holes 301 are provided on the connection plate 31 , and the connection holes 301 are connected to the lower truss beam 2 by means of bolts, so as to facilitate the disassembly and assembly of the truss for maintenance at a later stage.

[0042] like Figure 4As shown, the connecting hole 301 includes a sliding hole 3011 and a through hole 3012. The sliding hole 3011 and the through hole 3012 are both opened on the connecting plate 31, and the sliding hole 3011 penetrates to the bottom end of the connecting plate 31. The multiple sliding holes 3011 and the multiple through holes 3012 are arranged in a zigzag shape; when loading and assembling the truss, the bolt corresponding to the position of the sliding hole 3011 can be installed on the lower truss 2 first, and then the connecting plate 31 can be slid to slide the sliding hole 3011 to the outside of the bolt, and let the bolt head abut against the connecting plate 31. This method can not only quickly position the connecting plate 31 and the lower truss 2, but also improve the assembly efficiency of the two.

[0043] like Figure 4 As shown, the reinforcement plate 33 is provided with a reinforcement hole 302 and an avoidance hole 303. The reinforcement hole 302 and the through hole 3012 correspond to each other one by one, and are fixedly connected to the lower truss beam 2 by bolts. The bolts pass through the reinforcement hole 302, the through hole 3012 and the lower truss beam 2 in sequence; multiple sliding holes 3011 are all located in the avoidance hole 303; after the sliding hole 3011 slides to the outside of the bolt, the bolt at the sliding hole 3011 can be tightened to achieve pre-fixation of the connecting plate 31 and the lower truss beam 2, and then, the bolts are passed through the through holes 3012 and the reinforcement hole 302 to fix the reinforcement plate 33, the connecting plate 31 and the lower truss beam 2, thereby reinforcing the connecting plate 31 with the reinforcement plate 33, wherein the bolts fixed at the sliding hole 3011 will fall into the avoidance hole 303 to avoid mutual interference of components.

[0044] like Figure 3 As shown, the wrapping portion 34 is integrally formed on the bottom end of the reinforcing plate 33 and abuts against the bottom end of the connecting plate 31 , thereby preventing problems such as curling at the bottom of the connecting plate 31 .

[0045] In order to facilitate the sliding hole 3011 to slide into the outside of the bolt, it is preferred that the inner diameter of the sliding hole 3011 gradually increases from top to bottom.

[0046] like Figure 1 As shown, the guide member 3 is an arc-shaped structure, which can better guide the upper truss web assembly 4; and in order to improve its guiding effect, it is preferred that the wear-resistant plate 32 is flush with the inner wall of the installation groove 201 below the side close to the center line of the lower truss 2.

[0047] like Figure 1 As shown, the upper truss beam and web member assembly 4 includes an upper truss beam 41 and a web member 42. The bottom side of the upper truss beam 41 is provided with an assembly groove 401; the web member 42 is arranged between the two guide members 3, and its top end is fixed in the assembly groove 401, and its bottom end is fixed in the installation groove 201. The upper truss beam 41 and the web member 42 can be combined and fixed in advance to improve the assembly efficiency of the truss.

[0048] The method of using the docking guide structure for truss assembly of the utility model is as follows:

[0049] First, fix the lower truss 2 on the bracket 1, install the guide 3 on the lower truss 2, then combine and fix the upper truss 41 and the web 42 to form an upper truss web assembly 4, then hoist the upper truss web assembly 4 above the lower truss 2, and slowly move it downward, using the guide 3 to guide it into the installation groove 201, finally fix the web 42 and the lower truss 2, and remove the guide 3.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
