Description

Technical Field

[0001] The utility model belongs to the technical field of building construction and relates to a movable track, in particular to a movable track for assembling a large-span truss. Background Art

[0002] In recent years, with economic development, urban expansion, and changing social needs, people's expectations for architecture have also evolved, placing increasing demands on construction speed and methods. Large-span truss suspensory dome structures are commonly used in various civil buildings, such as stadiums and exhibition halls. These buildings are characterized by circular or elliptical structures, with each truss unit having essentially the same structure. Furthermore, steel structures, due to their stability, light weight, ease of shaping, production, and construction, are increasingly being used in large-span truss suspensory dome structures. In truss assembly projects, to better utilize these structural characteristics and expedite construction, a curved push-and-pull cumulative sliding construction technique is often employed. During this process, the assembled truss members are slid onto a reference platform to clear the installation area, ensuring smooth installation of the next truss member without requiring frequent movement of construction machinery. This reduces errors during construction, improves efficiency, and accelerates the construction schedule.

[0003] A search revealed a Chinese patent document that discloses a sliding track device for a space suspensory dome truss [Application Number: 202322635248.2; Publication Number: CN 220814972 U]. This sliding track device for a space suspensory dome truss belongs to the field of building construction technology. It comprises an outer ring steel column track and an intermediate ring beam track bracket. The intermediate ring beam track bracket is fixed to the center of the space suspensory dome installation and is coaxial with the intermediate ring beam of the truss. The intermediate ring beam track bracket supports the intermediate ring beam from the bottom and ensures its rotation around its center. The outer ring steel column track is a circular ring track that is coaxial with the truss and the intermediate ring beam track bracket. The outer ring steel column track is designed to adapt to the sliding roller structure at the bottom of the steel columns around the truss, ensuring that the sliding roller structure of the steel columns moves along the circular track. The utility model limits the track position of the space suspensory dome truss during the sliding process through the cooperation of the central high position and the outer low position track, so that it moves according to the prefabricated track, solves the stability and displacement position accuracy during the sliding process, and prevents overturning during the sliding process.

[0004] Although this patent solves the problem of stability and displacement accuracy during sliding and prevents overturning during sliding, it has the disadvantages of being bulky, difficult to process, and labor-intensive and time-consuming to assemble due to the main structure being an integrated structure. In addition, after the truss is assembled, the slide rail bracket is not easy to disassemble. Utility Model Content

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a mobile track for assembling large-span trusses. The technical problem to be solved by the present invention is: how to facilitate personnel to quickly disassemble the track after assembling the trusses, so as to facilitate personnel to transport and recycle it, and how to adjust the length of the track according to actual needs.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A movable track for assembling a large-span truss comprises a base and a pair of mutually parallel support plates fixed on the base, a plurality of reinforcing blocks connected to the base are fixed on the support plates, a connecting screw is fixed at one end of the base, an internally threaded barrel is rotatably connected to the other end of the base, and the internally threaded barrel is threadably matched with the connecting screw, and a regulating component for controlling the rotation of the internally threaded barrel is provided in the base.

[0008] The working principle of the utility model is that the internal threaded barrel can be controlled to rotate by the regulating component, so that the internal threaded barrel is threadedly connected to the connecting screw fixed on the other base, thereby realizing a quick fixed connection between the two rails, allowing personnel to adjust the length of the rails according to actual needs, and conveniently disassembling the rails quickly after assembling the truss, which is convenient for personnel to transport and recycle.

[0009] A plurality of drainage holes are formed through the two support plates.

[0010] With the above structure, the water flowing into the space between the two support plates can be discharged through the drainage hole, thereby preventing the water from accumulating for a long time and causing damage or rust to the support plate structure.

[0011] The regulating assembly includes a worm wheel rotatably connected within the base and a worm screw rotatably connected within the base. The worm wheel is coaxially fixedly connected to the internal threaded cylinder, and the worm wheel and the worm screw are meshed. A regulating wheel is provided on the base, and the regulating wheel and the worm screw are coaxially fixedly connected.

[0012] With the above structure, the worm can be driven to rotate by the regulating wheel. When the worm rotates, it will drive the worm wheel to rotate. When the worm wheel rotates, it will drive the internal threaded barrel to rotate. When the internal threaded barrel contacts the connecting screw, a threaded connection can be completed between the two, thereby completing a fixed connection between one base and another base to realize the laying of the track.

[0013] A plurality of weight-reducing grooves are arranged on the base.

[0014] By adopting the above structure, multiple weight-reducing grooves can be opened to reduce the weight of the base without affecting the overall structural strength, making it easier for personnel to carry and pave the base and improving overall operational efficiency.

[0015] A pair of pads are fixed on the bottom surface of the base, and a plurality of fixing holes are arranged on both pads, and expansion bolts are inserted into the fixing holes.

[0016] With the above structure, the pad can be fixed to the pre-opened holes on the ground by expansion bolts, and the base can be further fixed, so as to complete the normal assembly of the subsequent auxiliary truss.

[0017] Compared with the existing technology, this large-span truss assembly movable track has the following advantages:

[0018] 1. The internal threaded barrel is controlled to rotate by the regulating component, so that the internal threaded barrel is threadedly connected to the connecting screw fixed on the other base, thereby realizing a quick fixed connection between the two rails. This allows personnel to adjust the length of the rails according to actual needs, and facilitates personnel to quickly disassemble the rails after assembling the truss, which is convenient for personnel to transport and recycle.

[0019] 2. The water flowing into the space between the two support plates will flow out through the drainage hole to prevent the water from accumulating for a long time and causing damage or rust to the support plate structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figure 1-Figure 3As shown, a movable track for assembling a large-span truss comprises a base 1, a pair of mutually parallel support plates 2 fixed on the base 1, a plurality of reinforcing blocks 3 connected to the base 1 are fixed on the support plates 2, and a connecting screw 4 is fixed at one end of the base 1, and an internally threaded barrel 5 is rotatably connected to the other end of the base 1, and the internally threaded barrel 5 is threadedly matched with the connecting screw 4, and a regulating component for controlling the rotation of the internally threaded barrel 5 is provided in the base 1.

[0026] The internal threaded barrel 5 can be controlled to rotate through the regulating component, so that the internal threaded barrel 5 is threadedly connected to the connecting screw 4 fixed on the other base 1, thereby realizing a quick fixed connection between the two rails, allowing personnel to adjust the length of the rails according to actual needs, and making it convenient for personnel to quickly disassemble the rails after assembling the truss, thereby facilitating transportation and recycling.

[0027] A plurality of drainage holes 6 are formed through the two support plates 2 .

[0028] With the above structure, the water flowing into the space between the two support plates 2 can be discharged through the drainage hole 6, thereby preventing the water from accumulating for a long time and causing damage or rust to the support plate 2 structure.

[0029] The regulating component includes a worm gear 7 rotatably connected within the base 1 and a worm 8 rotatably connected within the base 1. The worm gear 7 is coaxially fixedly connected to the internal threaded barrel 5, and the worm gear 7 is meshed with the worm 8. A regulating wheel 9 is provided on the base 1, and the regulating wheel 9 is coaxially fixedly connected to the worm 8.

[0030] With the above structure, the worm 8 can be driven to rotate by the regulating wheel 9. When the worm 8 rotates, it will drive the worm wheel 7 to rotate. When the worm wheel 7 rotates, it will drive the internal threaded barrel 5 to rotate. When the internal threaded barrel 5 contacts the connecting screw 4, a threaded connection can be completed between the two, thereby completing a fixed connection between one base 1 and another base 1 to realize the laying of the track.

[0031] A plurality of weight-reducing grooves 10 are arranged on the base 1 .

[0032] By adopting the above structure, a plurality of weight-reducing grooves 10 can be provided to reduce the weight of the base 1 without affecting the overall structural strength, thereby facilitating transportation and installation by personnel and improving overall operational efficiency.

[0033] A pair of backing plates 11 are fixed to the bottom surface of the base 1 . A plurality of fixing holes 12 are arranged in the two backing plates 11 , and expansion bolts 13 are inserted into the fixing holes 12 .

[0034] With the above structure, the base plate 11 can be fixed to the pre-opened hole on the ground by the expansion bolts 13, and the base 1 can be further fixed, so that the subsequent auxiliary truss assembly can be carried out normally.

[0035] The working principle of the present invention is as follows: a single base 1 can be placed on the ground, and then the pad 11 can be fixed to the pre-opened hole on the ground by the expansion bolt 13, and the base 1 can be further fixed. At this time, the connecting screw 4 of the other base 1 can be brought into contact with the internal threaded tube 5 of the base 1 fixed on the ground. At this time, the regulating wheel 9 of the base 1 fixed on the ground is rotated, and the worm 8 is driven to rotate by the regulating wheel 9. After the worm 8 rotates, it will drive the worm gear 7 to rotate. After the worm gear 7 rotates, it will drive the internal threaded tube 5 to rotate. In this way, when the internal threaded tube 5 contacts the connecting screw 4, a threaded connection can be completed between the two, thereby completing the fixed connection between one base 1 and the other base 1. At this time, the other base 1 is fixed to the ground by the expansion bolt 13 to realize the laying of the track.

[0036] In summary, by controlling the internal threaded barrel 5 to rotate through the regulating component, the internal threaded barrel 5 is threadedly connected to the connecting screw 4 fixed on the other base 1, thereby realizing a quick fixed connection between the two rails, allowing personnel to adjust the length of the rails according to actual needs, and making it convenient for personnel to quickly disassemble the rails after assembling the truss, thereby facilitating transportation and recycling.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
