Description

Technical Field

[0001] This invention relates to the field of steel structure installation technology, specifically to a multi-functional adjustable transition structure for four-sloped roofs and its construction method. Background Technology

[0002] During the construction of large-span four-slope steel structure roofs, the steel structural components are factory-welded, but on-site assembly inevitably leads to welding deformation. Furthermore, cumulative installation deviations exist in the steel structural components during the installation phase. In addition, four-slope roofs have numerous multi-angle oblique corners and intersections of multiple slopes. Conventional fixed adapters and single-adjustable adapters exhibit significant construction defects, such as the inability to simultaneously compensate for differences in height, angle, and tilt of the four-slope roof, poor installation accuracy, numerous on-site modification procedures, low construction efficiency, and insufficient reliability of joint connections. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, a multi-functional adjustable transition structure for four-sloped roofs and its construction method are provided to solve the problem that conventional transition components cannot simultaneously compensate for the height difference, angle difference, and tilt angle difference of four-sloped roofs during the construction of large-span four-sloped steel structure roofs.

[0004] To achieve the above objectives, a multi-functional adjustable transition structure for a four-sloped roof is provided, comprising: The base is fixedly installed on the main steel structure; The substrate is mounted on the base in an adjustable position; A socket sleeve is vertically mounted on the base plate, and through holes are respectively opened on opposite sides of the sleeve wall; A plug-in column, the lower end of which is movably inserted into the socket sleeve; The locking structure includes two clamping seats, which are slidably disposed in the through hole. The side of the clamping seat facing the plug-in column has a plurality of protrusions arranged in a matrix. The outer wall of the plug-in column has a plurality of grooves arranged in a matrix. The clamping seat presses against the plug-in column. The plurality of protrusions are detachably inserted into the plurality of grooves. Arc-shaped plates are connected to opposite sides of the clamping seat. One end of the arc-shaped plates on the same side of the two clamping seats is connected together by a pull assembly. The support for installing the roof purlins is installed at the upper end of the plug-in column.

[0005] Furthermore, the bottom of the base has opposite sides turned down to form supporting vertical plates, which are erected on the horizontal tube of the main steel structure.

[0006] Furthermore, the substrate has multiple strip-shaped holes arranged along the length of the horizontal tube, and the base has multiple limiting rods vertically arranged. The limiting rods are slidably disposed in the strip-shaped holes, and the limiting rods are detachably mounted with pressing members. The pressing members press against the side of the substrate facing away from the base to lock the substrate.

[0007] Furthermore, the protrusion is in the shape of a regular square pyramid, and the shape of the groove is adapted to the shape of the protrusion.

[0008] Furthermore, an ear plate is formed at the end of the arc-shaped plate away from the clamping seat, and the pull assembly includes: A tie rod is provided, wherein the ear plate has through holes, and the tie rod is movably inserted through the through holes of the two ear plates; The locking components are adjustablely installed at both ends of the tie rod, and the locking components press against the outer side of the ear plate.

[0009] Furthermore, the two ends of the tie rod are formed with external threads, and the locking member has a threaded through hole, which is screwed into the end of the tie rod.

[0010] Furthermore, a through groove is formed on the top of the support, and the roof purlin is embedded in the through groove.

[0011] This invention provides a construction method for a multi-functional adjustable steel structure for a four-sloped roof, comprising the following steps: The base is fixedly installed on the main steel structure; The substrate is mounted on the base; Adjust the depth of the insertion of the plug-in column into the socket sleeve according to the roof elevation; Based on the multi-angle rotation and slope inclination angle of the four-sloped roof, rotate the plug-in column so that the support is set at the installation position of the roof purlin; The locking structure is installed on one end of the arc plate on the same side of the two clamping seats, so that the clamping seats press against the plug-in column, and multiple protrusions are detachably inserted into multiple grooves to lock the position of the support. The roof purlins are installed on the supports.

[0012] The beneficial effects of this invention are that the multi-functional adjustable transition structure for four-sloped roofs can achieve three-dimensional, all-around synchronous adjustment with strong compensation capabilities. Through lateral sliding adjustment of the base plate and pedestal, vertical pulling adjustment of the inserted column in the socket sleeve, and circumferential rotation adjustment, this multi-functional adjustable transition structure for four-sloped roofs can synchronously and accurately compensate for height differences, rotation angle differences, and tilt angle differences caused by welding deformation and cumulative installation deviations during the construction of large-span four-sloped steel roofs. This solves the technical problem that conventional fixed or single-adjustment transition components cannot cope with multi-dimensional deviation coupling. Attached Figure Description

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Reference Figures 1 to 5 As shown, the present invention provides a multi-functional adjustable transition structure for a four-sloped roof steel structure, comprising: a base 1, a base plate 2, a socket sleeve 3, a plug-in column 4, a locking structure 5, and a support 6.

[0022] The base 1 is fixedly installed on the main steel structure 7. In this embodiment, the base is elongated. The base is installed on the horizontal tube of the main steel structure. The base is arranged along the length of the horizontal tube.

[0023] In a preferred embodiment, the bottom sides of the base 1 are turned down to form supporting vertical plates 11. The supporting vertical plates 11 are erected on the horizontal tubes of the main steel structure 7.

[0024] Preferably, the lower side of the supporting vertical plate is welded to the circumferential surface of the horizontal tube.

[0025] The substrate 2 is mounted on the base 1 in an adjustable position. Specifically, the substrate can be mounted on the base in an adjustable position along the length of the transverse tube.

[0026] Specifically, the substrate 2 has multiple strip-shaped holes 20. The strip-shaped holes 20 are arranged along the length direction of the horizontal tube. The base 1 is vertically provided with multiple limiting rods. The limiting rods are slidably disposed in the strip-shaped holes 20. The limiting rods are detachably mounted with pressing members. The pressing members press against the side of the substrate 2 facing away from the base 1 to lock the substrate 2.

[0027] In this embodiment, the limiting rod is a screw. The pressing member has a threaded hole. The pressing member is screwed onto the screw. The pressing member presses against the side of the substrate facing away from the base to lock the substrate onto the base.

[0028] The socket sleeve 3 is vertically mounted on the base plate 2. Through holes 30 are respectively opened on opposite sides of the sleeve wall. The lower end of the insertion post 4 is movably inserted into the socket sleeve 3.

[0029] In this embodiment, the socket sleeve is cylindrical. The outer diameter of the insertion post is adapted to the outer diameter of the socket sleeve. The insertion post can move along the axial direction of the socket sleeve and can rotate within the socket sleeve.

[0030] Combination Figure 3 and Figure 4 As shown, the locking structure 5 includes a clamping seat 51 and an arc-shaped plate 52.

[0031] The clamping seat 51 is slidably disposed in the through hole 30. Multiple protrusions 511 arranged in a matrix are formed on the side of the clamping seat 51 facing the insertion post 4. Multiple recesses arranged in a matrix are formed on the outer wall of the insertion post 4. The clamping seat 51 presses against the insertion post 4. The multiple protrusions 511 are detachably inserted into the multiple recesses.

[0032] Arc-shaped plates 52 are connected to opposite sides of the clamping base 51. The other side of the clamping base facing away from the insert column is connected to the arc-shaped plate 52. One end of the arc-shaped plates 52 on the same side of the two clamping bases 51 is connected together by a pull assembly 53.

[0033] In this embodiment, the curvature of the arc plate is adapted to the curvature of the circumferential surface of the socket sleeve.

[0034] Support 6 is installed at the upper end of the plug-in column 4. Support 6 is used to install the roof purlin 71. For details, please refer to [link / reference]. Figure 2 As shown, a through groove is formed at the top of the support 6. A roof purlin 71 is embedded in the through groove. One end of the roof purlin is embedded in the through groove. Each support supports the ends of two roof purlins.

[0035] Continue to combine Figure 3 and Figure 4 As shown, the protrusion 511 is in the shape of a regular square pyramid. The shape of the groove is adapted to the shape of the protrusion 511. In this embodiment, the circumferential surface of the insertion post is covered with multiple grooves. The multiple grooves are arranged in a matrix. By inserting the protrusion into the grooves in different areas of the circumferential surface of the insertion post, the insertion depth of the insertion post and the relative position of the insertion post and the socket sleeve in the circumferential direction are locked.

[0036] In this embodiment, an ear plate 521 is formed at the end of the arc-shaped plate 52 away from the clamping seat 51. The pull assembly 53 includes a pull rod 531 and a locking member 532.

[0037] The ear plate 521 has a through hole. The tie rod 531 is movably inserted into the through holes of the two ear plates 521. The two ends of the tie rod 531 are respectively equipped with locking members 532 in adjustable positions. The locking members 532 press against the outer side of the ear plate 521.

[0038] The tie rod 531 has external threads at both ends. The locking member 532 has threaded through holes. The threaded through holes of the locking member are screwed into the ends of the tie rod 531.

[0039] This invention provides a construction method for a multi-functional adjustable steel structure for a four-sloped roof, comprising the following steps: S1. Fix the base 1 to the main steel structure 7.

[0040] In the factory, the base plate is fully welded to the bottom of the socket sleeve, and the support is fully welded to the top of the plug column. All components are made of Q355B building structural steel. After welding, the whole is treated with anti-corrosion galvanizing to form prefabricated components.

[0041] The base is transported to the corresponding node position of the main steel structure, so that the supporting vertical plate at the bottom of the base straddles the horizontal tube of the main steel structure, and the lower side of the supporting vertical plate is welded and fixed to the circumference of the horizontal tube, thus completing the positioning and installation of the base.

[0042] S2. Mount the substrate 2 onto the base 1.

[0043] Place the substrate on the top surface of the base, so that the pre-embedded limiting rod on the base passes through the strip hole on the substrate. According to the design axis position of the roof purlin, slide the substrate along the length of the horizontal tube to adjust its lateral position on the base. After it is in place, screw in the pressing part (nut) to tighten the substrate and achieve temporary fixation of the substrate.

[0044] S3. Adjust the depth of the insertion of the plug column 4 into the socket sleeve 3 according to the roof elevation.

[0045] Insert the lower end of the plug-in column into the socket sleeve from top to bottom. Based on the measured data of the roof panel height (to compensate for the height difference caused by the welding deformation of the steel structure and the cumulative deviation of installation), pull the plug-in column up and down to adjust its insertion depth into the socket sleeve until the top surface elevation of the support reaches the design value.

[0046] S4. Based on the multi-angle rotation and slope inclination of the four-sloped roof, rotate the plug-in column 4 so that the support 6 is set at the installation position of the roof purlin 71.

[0047] Based on the multi-angle rotation and slope inclination of the four-sloped roof, the column is inserted and rotated circumferentially inside the socket sleeve to align the through groove of the support with the installation position of the roof purlin, eliminating the difference in rotation and inclination, and ensuring accurate alignment between the support and the purlin.

[0048] S5. Install the pull-out assembly 53 of the locking structure 5 onto one end of the arc plate 52 on the same side of the two clamping seats 51, so that the clamping seats 51 press against the plug-in column 4, and multiple protrusions 511 are detachably inserted into multiple grooves to lock the position of the support 6.

[0049] Slide the two clamping seats into the perforations on both sides of the sleeve wall, so that the matrix protrusions on the inner side of the clamping seats are aligned with the matrix grooves on the outer wall of the insertion column.

[0050] Pass the tie rod of the tie assembly through the ear plate through hole at the end of the arc plate on the same side of the two clamping seats, and screw the locking parts into both ends of the tie rod. Gradually tighten the locking parts so that the two clamping seats are clamped together in the middle and the protrusion is embedded in the groove, thereby simultaneously locking the vertical height and circumferential angle position of the plug-in column.

[0051] S6. Install the roof purlin 71 onto the support 6.

[0052] Re-measure the elevation of the top surface of the support, the orientation of the roof corner, and the inclination angle of the slope to confirm that all installation accuracy meets the design and specification requirements. If there is any deviation, loosen the locking structure and repeat steps four to six for fine-tuning until it is qualified.

[0053] After the accuracy acceptance is qualified, the outer wall of the pipe section where the plug column and the socket sleeve overlap is continuously welded in a ring. The weld is full and free of porosity and slag inclusion, forming a rigid integral connection.

[0054] Remove welding slag, apply anti-corrosion primer and topcoat to the weld seam, and complete the node construction.

[0055] The ends of the roof purlins are embedded in the through grooves at the top of the supports, and the purlins are fixedly connected to the supports with fasteners to complete the construction of the entire adjustable transition structure.

[0056] The multi-functional adjustable transition structure for four-sloped roofs of this invention enables synchronous adjustment in all three dimensions with strong compensation capabilities. Through lateral sliding adjustment of the base plate and pedestal, vertical pulling adjustment of the insert column within the socket sleeve, and circumferential rotation adjustment, this multi-functional adjustable transition structure for four-sloped roofs of this invention can synchronously and accurately compensate for height differences, rotation angle differences, and tilt angle differences caused by welding deformation and cumulative installation deviations during the construction of large-span four-sloped steel roofs. This solves the technical problem that conventional fixed or single-adjustment transition components cannot cope with multi-dimensional deviation coupling.

[0057] The multi-functional adjustable steel structure for four-sloped roofs of this invention employs a matrix-style protrusion and groove locking structure, ensuring precise positioning and reliable anti-slip performance. The clamping seat in the locking structure of this multi-functional adjustable steel structure for four-sloped roofs features a matrix-arranged regular square pyramidal protrusion, which, in conjunction with the matrix-style grooves on the outer wall of the insertion column, achieves multi-tooth engagement during locking. This structure not only provides fine-grained, precise adjustment at any height and angle, but also, by simultaneously embedding multiple protrusions into the grooves, increases the contact area and shear resistance, effectively preventing vertical slippage or circumferential rotation of the insertion column under stress, significantly improving the stability of the joint connection.

[0058] This invention provides a multi-functional adjustable steel structure for four-sloped roofs that combines temporary locking with permanent welding, balancing construction convenience with structural safety. During construction, the multi-functional adjustable steel structure for four-sloped roofs first achieves rapid temporary locking via the tie rod components of the locking structure, facilitating quick fine-tuning if the accuracy is not up to standard during re-measurement. After the accuracy is verified, the overlapping sections of the insert columns and socket sleeves are then circumferentially welded to form a permanent rigid connection. This "adjust first, lock later, weld later" process design ensures both flexible adjustment space during installation and guarantees the structural rigidity and long-term reliability of the final node.

[0059] The multi-functional adjustable transition structure for four-sloped roofs of this invention, referring to modular prefabrication assembly, significantly improves construction efficiency and reduces on-site modifications. The base plate, socket sleeve, supports, and plug-in columns of the multi-functional adjustable transition structure for four-sloped roofs of this invention can all be prefabricated and integrally welded in the factory, requiring only simple hoisting, insertion, and locking operations on-site. The strip-shaped hole design on the base plate allows for rapid alignment along the length of the horizontal pipe, eliminating the need for secondary drilling or cutting modifications on-site, significantly reducing the amount of welding and modification work at height, greatly improving construction efficiency and reducing safety risks.

[0060] The standardized design of the components in the multi-functional adjustable transition structure for four-sloped roofs of this invention offers excellent versatility and adaptability. All components of the multi-functional adjustable transition structure for four-sloped roofs of this invention are made of Q355B structural steel and uniformly treated with anti-corrosion galvanizing, ensuring both structural load-bearing capacity and enhanced corrosion resistance. This transition structure can flexibly adapt to the intersection of multi-sloped roofs with different slopes and angles, possessing strong versatility and promotional value, and can be widely applied to various complex spatial steel structure roofing projects.

[0061] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
