Description

TECHNICAL FIELD

[0001] The utility model belongs to roof system technical field, concretely relates to a kind of pipe row frame connecting node and roof system and building. BACKGROUND

[0002] In the roof design of large-span or heavy-load industrial plant, roof bracket system is a common solution. There are currently three types of roof brackets on the market: angle steel truss, profile steel truss and pipe truss. These different types of trusses have their own advantages and disadvantages, which affect their selection in practical application.

[0003] Although angle steel truss is widely used, it has poor appearance and cannot meet the requirements of modern architecture. Profile steel truss has disadvantages in economy, often leading to increased engineering costs. In comparison, pipe truss has obvious advantages in bearing capacity, appearance and economy, and has become the first choice for many engineering projects.

[0004] However, pipe truss faces some important challenges during construction. First, since pipe truss is usually used in structures with high height and large span, its size is often large, which leads to difficulty in overall transportation, especially when the steel structure company is not on the project site, the transportation cost and difficulty increase significantly.

[0005] Secondly, due to transportation restrictions, pipe trusses often need to be welded and assembled on site. This approach brings a series of problems: a large amount of on-site welding, and the non-planar connection of pipe trusses makes it difficult to ensure the quality of the weld. In addition, on-site welding also faces the problem of positioning accuracy. Due to the lack of precision equipment and ideal conditions in the factory environment, on-site measurement and welding are prone to large errors.

[0006] These construction difficulties not only affect engineering efficiency, but also may endanger structural safety. Reports indicate that there have been cases where the spacing between the web bars and the main pipe exceeds 5 cm due to excessive on-site welding errors. In such cases, some construction parties use welding slag to fill the connection, which greatly reduces the strength of the node and may cause serious safety accidents during later use.

[0007] Therefore, it is urgent to develop a pipe row frame connecting node to facilitate the quick connection between the top and bottom chords and the web bars of various pipe trusses. UTILITY MODEL CONTENTS

[0008] To solve the problems in the background art, the utility model aims to provide a pipe row frame connecting node, roof system and building, which has the advantages of easy processing, transportation and assembly, high splicing accuracy and few welding defects.

[0009] To achieve the above object, the utility model discloses a kind of pipe row frame connecting nodes, including main chord and web, the main chord is connected with sleeve, the sleeve is coaxially arranged with the web, web mounting hole is provided on the sleeve, at least one welding seam extending along its axial direction, radial penetration is provided on the sleeve.

[0010] In a preferred embodiment of the utility model, the welding seam includes at least two, four welding seams are rotationally symmetrically arranged relative to the central axis of the sleeve.

[0011] In a preferred embodiment of the utility model, there is an included angle between the central axis of the main chord and the central axis of the sleeve.

[0012] In a preferred embodiment of the utility model, the main chord and the sleeve are welded.

[0013] In a preferred embodiment of the utility model, the end of the sleeve is provided with the same profiling groove as the outer peripheral surface of the main chord.

[0014] In a preferred embodiment of the utility model, the sleeve and the web are fixed by the welding seam.

[0015] In a preferred embodiment of the utility model, the central axis of the sleeve and the central axis of the main chord form an included angle.

[0016] In a preferred embodiment of the utility model, the diameter of the web mounting hole corresponds to the outer diameter of the web.

[0017] The utility model also discloses a roof system, including the pipe row frame connecting node.

[0018] The utility model also discloses a building, package roof system.

[0019] The utility model has the advantages that: the solution provided by the utility model effectively overcomes many problems of existing pipe truss in transportation, installation and welding. It not only simplifies the construction process and improves the precision, but also significantly reduces the amount of field welding and welding defects. This innovative design greatly improves the reliability of the structure and the convenience of construction, and has significant practical value and broad popularization prospect.

[0020] Firstly, the utility model connects sleeve on main chord, and sets web mounting hole and welding seam on sleeve, which greatly simplifies the connection process of pipe truss. This design enables web to be easily inserted into sleeve and fixed through welding seam, significantly improving construction efficiency and precision. Especially noteworthy is that sleeve is factory-made, and the length is moderate, which does not affect transportation, solving the problem of difficult transportation of large pipe truss.

[0021] Secondly, the design of the utility model allows the pipe truss to prefabricate main components in the factory, and then quickly assemble on site. This not only reduces the amount of welding on site, but also improves the welding quality and the safety of the overall structure. More importantly, the sleeve angle can be accurately machined in the factory according to design requirements, avoiding errors caused by positioning on site and ensuring the accuracy of the connection.

[0022] Thirdly, the innovative design significantly reduces the difficulty of on-site splicing. The connection of the web member changes from traditional butt joint to simple splicing, greatly reducing the error. At the same time, this design allows the splicing of the web member to be completed first, and then welding, avoiding the difficulty of splicing and welding at the same time, and improving the construction efficiency and quality.

[0023] Fourthly, the utility model greatly reduces the welding difficulty. By converting curved welding to flat welding, the generation of welding defects is significantly reduced. The multiple weld seams provided on the sleeve not only provide a larger welding area, but also ensure more uniform stress distribution, enhancing the strength and stability of the connection node.

[0024] Fifthly, the design of the utility model has good flexibility. There can be a certain angle between the main chord and the sleeve, and this flexibility makes the connection node adaptable to different structural design requirements, increasing its application range.

[0025] Finally, the profiled groove provided at the end of the sleeve is attached to the outer peripheral surface of the main chord, which not only improves the stability of the connection, but also improves the aesthetics of the overall structure. This design concept can be applied to the entire roofing system and building, improving the construction efficiency, structural safety and aesthetics of the overall building.

[0029] The technical solutions of the utility model (including the preferred technical solutions) will be described in further detail below by means of the accompanying drawings and by listing some optional embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] As Figs. 1-3 shown, the utility model provides a kind of pipe row frame connecting node, cleverly solve the many challenges that current pipe truss faces in construction process, it is applicable to various pipe truss upper and lower chord and web member connecting node.This connecting node is mainly composed of three core components: main chord 1, sleeve pipe 2 and web member 3.These three components form a stable, efficient structural unit by carefully designed connecting mode, provide solid foundation for entire pipe truss system.

[0031] The connection between main chord 1 and sleeve pipe 2 is the basis of the entire node design.The two components are firmly fixed together by welding, and the end of sleeve pipe 2 is provided with the same profiled groove as the outer peripheral surface of main chord 1.This profiled groove design not only ensures the perfect fit between sleeve pipe 2 and main chord 1, enhances the stability of connection, but also improves the overall structure's appearance, makes the connection look more coordinated.

[0032] Sleeve pipe 2 is one of the most critical components in this design.It is pre-made in factory, and 4 slots are cut on its surface as welding seams 4.These welding seams 4 extend along the axial direction of sleeve pipe 2, and are radially through.The number of welding seams 4 is at least two, ideally four, and the four welding seams 4 are arranged rotationally symmetrically relative to the central axis of sleeve pipe 2.This symmetrical arrangement not only provides a larger welding area, but also ensures uniform force distribution, further enhances the strength and stability of the connecting node.

[0033] Sleeve pipe 2 is provided with web member mounting hole, and its diameter is accurately corresponding to the outer diameter of web member 3.This accurate size matching ensures that web member 3 can be inserted stably into sleeve pipe 2, reduces installation error, and improves the stability of overall structure.In actual installation process, web member 3 is inserted into the web member mounting hole of sleeve pipe 2, and then fixed by welding seam 4.This design changes the originally complex curved welding into relatively simple plane welding, greatly reduces the welding difficulty and reduces the generation of welding defects.

[0034] There can be a certain included angle between the central axis of main chord 1 and the central axis of sleeve pipe 2.This design gives the connecting node great flexibility, enabling it to adapt to various structural design requirements.Whether it is right-angle connection or oblique-angle connection, this node design can easily cope with, greatly increasing its application range.

[0035] The thickness and length of sleeve pipe 2 are determined by the requirements of welding seam.This design takes into account the requirements of structural strength and welding process, ensures the reliability and durability of connecting node.At the same time, since the size of sleeve pipe 2 is moderate, it will not affect transportation, and cleverly solves the problem of difficult transportation of large pipe truss.

[0036] In actual construction process, the sleeve 2 is pre-welded to the main chord 1 in the factory, and 4 notches are cut on the sleeve 2 as welding seams. This prefabrication method greatly simplifies the on-site construction process. The construction personnel only need to insert the diagonal web member into the sleeve and weld in the welding seam to complete the installation. This method not only reduces the difficulty of on-site construction, but also significantly improves the construction efficiency and quality.

[0037] Welding is a key step to ensure the stability of the connection node. In this design, welding mainly occurs in two places: one is the welding between the main chord 1 and the sleeve 2, which is completed in the factory; the other is the welding between the sleeve 2 and the web member 3 through the welding seam 4, which is completed on site. By dividing the complex welding work into two stages of factory and site, the welding quality and efficiency are greatly improved.

[0038] The application range of the utility model is very wide. It can not only be used as a single pipe row frame connection node, but also as a component part of a larger system. For example, the utility model also discloses a roof system comprising the pipe row frame connection node, and a building comprising the roof system. In the roof system, multiple such connection nodes work together to form a stable and efficient structural network. In the whole building, this roof system can be perfectly combined with other building elements to improve the performance of the whole building.

[0039] The pipe row frame connection node provided by the utility model effectively solves many problems of existing pipe trusses in transportation, installation and welding through its unique design. It not only simplifies the construction process and improves the precision, but also significantly reduces the amount of on-site welding and welding defects. This innovative design greatly improves the reliability of the structure and the convenience of construction, and has significant practical value and broad application prospects.

[0040] Through the carefully designed component connection relationship, the utility model successfully converts the complex engineering problem into a simple and efficient solution. It not only meets the requirements of engineering technology, but also considers the needs of actual construction and later use, and is a comprehensive and mature technical innovation. The application of this design concept not only improves the performance of the single connection node, but also plays a greater role in the whole building system, providing more possibilities and efficiency improvement for modern building engineering.

[0041] As can be easily understood by those skilled in the art, the above is only a preferred embodiment of the utility model, and does not limit the utility model. Any modification, combination, replacement, improvement, etc. made within the spirit and principles of the utility model is included in the protection scope of the utility model.
