Description

Technical Field

[0001] This invention belongs to the field of truss structure foundation technology, and particularly relates to a spliced ​​compression-resistant large-span aerial truss steel structure for buildings. Background Technology

[0002] In truss structures, a truss refers to a truss beam, a type of latticed beam structure. Truss structures are commonly used in public buildings such as large-span factories, exhibition halls, stadiums, and bridges. Because they are mostly used in roof structures, trusses are often also called roof trusses. The forces on each member of a truss are primarily unidirectional tension and compression. Through the proper arrangement of the upper and lower chords and web members, the distribution of bending moments and shear forces within the structure can be accommodated.

[0003] In existing technologies, the members of a large-span truss structure are assembled by forming a frame with mutually perpendicular angles. When facing lateral pressure, the middle position of the member is subjected to greater pressure, and the middle position may break due to lack of coordination. Summary of the Invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a spliced ​​compression-resistant large-span building aerial truss steel structure.

[0005] This invention proposes a spliced, compression-resistant, large-span aerial truss steel structure for buildings, which includes multiple sets of frame components. Each set of frame components includes a first mounting member, a second mounting member, a third mounting member, and a fourth mounting member. The first and third mounting members are connected vertically, and the second and fourth mounting members are also connected vertically. The first and second mounting members are horizontally opposite each other, and the third and fourth mounting members are horizontally opposite each other.

[0006] Multiple fixed shafts are sequentially and equidistantly fixedly connected to the same side of the first and third mounting rods. Multiple fixed shafts are sequentially and equidistantly welded to the same side of the second and fourth mounting rods. Two adjacent fixed shafts are connected by an inclined support shaft. The fixed shafts are provided with mounting grooves. A pressing mechanism is provided in the mounting grooves. A connecting sleeve is slidably engaged in the mounting grooves. The pressing mechanism abuts against the connecting sleeve. A side mounting block is provided at one end of the connecting sleeve. The side mounting block is engaged with the support shaft.

[0007] The first mounting rod and the second mounting rod are connected together by a plurality of first connecting shafts, and the third mounting rod and the fourth mounting rod are connected together by a plurality of first connecting shafts;

[0008] Two adjacent sets of the frame components are connected together by a plurality of second connecting axes.

[0009] Preferably, a circular cross-section locking block is fixedly connected to the side mounting block, and a slot for cooperating with the locking block is opened on the support shaft. The locking block is inserted into the slot, and the distance between the inner wall of the side mounting block and the outer surface of the fixed shaft is the thickness of one support shaft.

[0010] Preferably, the first and third mounting rods are welded to both ends of the fixed shaft, and the second and fourth mounting rods are welded to both ends of the fixed shaft. The fixed shafts on the first and second mounting rods are installed upside down, with the opening of the mounting groove of the fixed shaft on one side facing upward and the opening of the mounting groove of the fixed shaft on the other side facing downward.

[0011] Preferably, the pressing mechanism includes a spring and a pressing ring. One end of the spring is fixedly connected to the inner wall of the mounting groove, and the other end of the spring is fixedly connected to the pressing ring. The pressing ring is slidably sleeved on one side of the mounting groove and abuts against the connecting sleeve. A filling block is also fixedly installed in the mounting groove, and the side of the connecting sleeve away from the pressing ring abuts against the filling block.

[0012] Preferably, the filler block is threaded with bolts, the bolts are also threaded through the fixed shaft, and nuts are threaded at both ends of the bolts.

[0013] Preferably, the first mounting rod, the second mounting rod, the third mounting rod, and the fourth mounting rod are each provided with a plurality of mounting holes, and the two ends of the first connecting shaft are respectively connected to the mounting holes on the first mounting rod and the second mounting rod, and the positions of the two mounting holes are staggered.

[0014] Preferably, both ends of the second connecting shaft are also respectively engaged with two mounting holes, which are located on two sets of frame assemblies, and the extension lines of the first connecting shaft and the second connecting shaft intersect each other.

[0015] Preferably, an auxiliary shaft is further provided between the first connecting shaft and the second connecting shaft. Both ends of the auxiliary shaft are provided with retaining pins. Holes for inserting the retaining pins are opened at both ends of the first connecting shaft and the second connecting shaft. The two retaining pins of the auxiliary shaft are respectively inserted into the holes on the first connecting shaft and the second connecting shaft.

[0016] Compared with existing technologies, the beneficial effects of the spliced ​​compression-resistant large-span aerial truss steel structure of the present invention are:

[0017] 1. Two adjacent frame components are connected by a second connecting shaft. When pressure is applied from one side of the first connecting shaft toward the second connecting shaft, the second connecting shaft can effectively disperse a certain amount of pressure.

[0018] 2. The first and second connecting shafts can effectively disperse the pressure from the horizontal plane, and the fixed shaft can effectively withstand the pressure from the vertical plane, thus making the overall structure stable and able to withstand pressure well, avoiding the problem of breakage in the middle.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figures 1-6A spliced ​​compression-resistant large-span aerial truss steel structure includes multiple sets of frame components. Each frame component includes a first mounting member 1, a second mounting member 2, a third mounting member 6, and a fourth mounting member 7. The first mounting member 1 and the third mounting member 6 are connected vertically, as are the second mounting member 2 and the fourth mounting member 7. The first mounting member 1 and the second mounting member 2 are horizontally opposite each other, as are the third mounting member 6 and the fourth mounting member 7.

[0028] Multiple fixed shafts 8 are sequentially and equidistantly fixedly connected to the same side of the first mounting rod 1 and the third mounting rod 6. Multiple fixed shafts 8 are also sequentially and equidistantly welded to one side of the second mounting rod 2 and the fourth mounting rod 7. Two adjacent fixed shafts 8 are connected together by a support shaft 5. The support shaft 5 is inclined. A mounting groove 12 is provided on the fixed shaft 8. A pressing mechanism is provided in the mounting groove 12. A connecting sleeve 17 is slidably engaged in the mounting groove 12. The pressing mechanism abuts against the connecting sleeve 17. A side mounting block 11 is provided at one end of the connecting sleeve 17. The side mounting block 11 is engaged with the support shaft 5.

[0029] The first mounting rod 1 and the second mounting rod 2 are connected together by a plurality of first connecting shafts 3, and the third mounting rod 6 and the fourth mounting rod 7 are also connected together by a plurality of first connecting shafts 3; two adjacent sets of frame assemblies are connected together by a plurality of second connecting shafts 9.

[0030] In this embodiment, a locking block 16 is fixedly connected to the side mounting block 11, and a slot 20 is provided on the support shaft 5 to cooperate with the locking block 16. The locking block 16 is inserted into the slot 20. The cross-section of the locking block 16 is circular. The distance between the inner wall of the side mounting block 11 and the outer surface of the fixed shaft 8 is the thickness of one support shaft 5. The connecting sleeve 17 is locked together with one end of the support shaft 5 through the side mounting block 11. The two connecting sleeves 17 cooperate with each other so that the two ends of the support shaft 5 are respectively connected to the two fixed shafts 8 to achieve the connection effect.

[0031] In this embodiment, the fixed shaft 8 is welded to the first mounting rod 1, the second mounting rod 2, the third mounting rod 6, and the fourth mounting rod 7. The fixed shafts 8 on the first mounting rod 1 and the second mounting rod 2 are installed upside down, with the opening of the mounting groove 12 of one fixed shaft 8 facing upwards and the opening of the mounting groove 12 of the other fixed shaft 8 facing downwards. By inverting the two adjacent fixed shafts 8, the support shaft 5 can form an inclined installation angle when connected to it. The inclined support shaft 5 can better withstand pressure. The support shaft 5 and the fixed shaft 8 can be combined to form a triangular structure, which has the effect of enhancing stability.

[0032] In this embodiment, the pressing mechanism includes a spring 13 and a pressing ring 14. One end of the spring 13 is fixedly connected to the inner wall of the mounting groove 12, and the other end of the spring 13 is fixedly connected to the pressing ring 14. The pressing ring 14 is slidably sleeved on one side of the mounting groove 12 and abuts against the connecting sleeve 17. A filling block 15 is also fixedly installed in the mounting groove 12. The side of the connecting sleeve 17 away from the pressing ring 14 abuts against the filling block 15. The upper and lower sides of the connecting sleeve 17 are clamped and fixed by the pressing ring 14 and the filling block 15, respectively. The gap is filled with the spring 13, and the elastic force of the spring 13 keeps the pressing stable.

[0033] In this embodiment, a bolt 19 is threaded through the filler block 15, and the bolt 19 is also threaded through the fixed shaft 8. Nuts 18 are threaded at both ends of the bolt 19. The filler block 15 is fixed by the bolt 19 and installed in the mounting groove 12. The bolt 19 is threaded through the inner wall of the opening of the mounting groove 12 and the filler block 15, and its two ends are fixed by the nuts 18, thereby achieving the effect of fixing the filler block 15 in the mounting groove 12.

[0034] In this embodiment, multiple mounting holes 21 are provided on the first mounting rod 1, the second mounting rod 2, the third mounting rod 6, and the fourth mounting rod 7. The two ends of the first connecting shaft 3 are respectively connected to the mounting holes 21 on the first mounting rod 1 and the second mounting rod 2. The positions of the two mounting holes 21 are staggered. The two ends of the first connecting shaft 3 can be connected to the first mounting rod 1 and the second mounting rod 2 respectively through insert shafts. On the other hand, the two ends of the first connecting shaft 3 can also be connected to the third mounting rod 6 and the fourth mounting rod 7 respectively through insert shafts. Since the relative positions of the mounting holes 21 are staggered, a parallelogram structure can be formed between the two first connecting shafts 3, the first mounting rod 1, and the second mounting rod 2, increasing the stability of the overall structure.

[0035] In this embodiment, both ends of the second connecting shaft 9 are also respectively engaged with two mounting holes 21. The two mounting holes 21 are located on the two sets of frame components respectively. The extension lines of the first connecting shaft 3 and the second connecting shaft 9 intersect each other. The first mounting rod 1 and the second mounting rod 2 are connected through the first connecting shaft 3, as well as the third mounting rod 6 and the fourth mounting rod 7. The two sets of frame components are connected through the second connecting shaft 9. The first connecting shaft 3 and the second connecting shaft 9 form a cross structure. When both sides are subjected to force, the first connecting shaft 3 or the second connecting shaft 9 on the other side can provide a reverse blocking structure, which helps to stabilize the structure.

[0036] In this embodiment, an auxiliary shaft 4 is also provided between the first connecting shaft 3 and the second connecting shaft 9. Both ends of the auxiliary shaft 4 are provided with retaining pins 10. The two retaining pins 10 are respectively inserted into the first connecting shaft 3 and the second connecting shaft 9. Holes for inserting the retaining pins 10 are opened at both ends of the first connecting shaft 3 and the second connecting shaft 9. By connecting and fixing the two ends of the auxiliary shaft 4 to one end of the first connecting shaft 3 and the second connecting shaft 9 respectively, the installation of the first connecting shaft 3 and the second connecting shaft 9 can be realized through the auxiliary shaft 4, thus realizing the installation between the two sets of frame components.

[0037] When assembling this invention, preparatory work is first carried out. The first mounting rod 1 and the third mounting rod 6 are paired, and the second mounting rod 2 and the fourth mounting rod 7 are paired. The pressing mechanism is pre-installed in the mounting groove 12. Then, the overall structure is assembled. First, the two fixed shafts 8 are connected together by the support shaft 5. The connecting sleeve 17 is put into the opening of the mounting groove 12. During the insertion process, one end of the support shaft 5 is inserted from one side of the side mounting block 11, so that the locking block 16 is inserted into the locking groove 20, realizing the connection between the side mounting block 11 and the support shaft 5. As the connecting sleeve 17 slides into the inner position of the mounting groove 12, the support shaft 5 will fit together with the outer surface of the fixed shaft 8 to form a connection structure.

[0038] Then, the upper and lower ends of the fixed shaft 8 are welded to one side of the first mounting rod 1 and the third mounting rod 6, and to one side of the second mounting rod 2 and the fourth mounting rod 7. The upper and lower angle positions of the fixed shaft 8 welded on the first mounting rod 1 and the second mounting rod 2 are reversed. After the fixed shaft 8 is welded, the filling block 15 is installed at the opening of the mounting groove 12. The bolt 19 is threaded through the inner wall of the mounting groove 12 and the filling block 15. Nuts 18 are threaded on both ends of the bolt 19 for fixation. The spring 13 in the pressing mechanism applies force to the pressing ring 14. The pressing ring 14 and the filling block 15 at the upper and lower positions of the connecting sleeve 17 cooperate with each other to clamp and fix the connecting sleeve 17 in the middle. Thus, the fixed shaft 8 and the support shaft 5 can be combined to form a triangular structure. When the fixed shaft 8 is subjected to external pressure, it will be transmitted to the support shaft 5. The angle tilt of the support shaft 5 can better unload the pressure, and the pressure area will increase due to the angle tilt.

[0039] Finally, the first mounting rod 1 and the second mounting rod 2 are connected together by the first connecting shaft 3. The third mounting rod 6 and the fourth mounting rod 7 are also connected together by the first connecting shaft 3. Mounting holes 21 are provided on the first mounting rod 1, the second mounting rod 2, the third mounting rod 6, and the fourth mounting rod 7. Insert shafts can be provided at both ends of the first connecting shaft 3. The connection is achieved by inserting the insert shafts into the mounting holes 21. The two ends of the first connecting shaft 3 are respectively installed on the mutually staggered mounting holes 21, forming a non-right-angled structure. Therefore, when the first mounting rod 1 or the second mounting rod 2 faces the pressure in the front on a plane perpendicular to the first connecting shaft 3, the obliquely set first connecting shaft 3 can withstand greater pressure and effectively disperse the pressure, thereby avoiding the problem of breakage.

[0040] Two adjacent frame components are connected by a second connecting shaft 9. The two ends of the second connecting shaft 9 are also installed on mutually staggered mounting holes 21, and the extension line of the first connecting shaft 3 intersects the second connecting shaft 9. Thus, when pressure is applied from the side of the first connecting shaft 3 toward the second connecting shaft 9, the second connecting shaft 9 can effectively disperse a certain amount of pressure. Similarly, when pressure is applied from the side of the second connecting shaft 9 toward the first connecting shaft 3, the first connecting shaft 3 can disperse the pressure.

[0041] In addition to direct installation by inserting the first connecting shaft 3 and the second connecting shaft 9 into the mounting holes 21, installation can also be performed through the auxiliary shaft 4. Since the two frame components are connected adjacent to each other, the first mounting rod 1 and the second mounting rod 2 form an alternating structure. On one side of a set of frame components, the two ends of the auxiliary shaft 4 are fixed by the clamping shaft 10 to install one end of the first connecting shaft 3 and the second connecting shaft 9 respectively. On the other side of the frame components, the other ends of the first connecting shaft 3 and the second connecting shaft 9 are fixed by the auxiliary shaft 4. Thus, the first connecting shaft 3 and the second connecting shaft 9 can be installed and fixed simultaneously through the auxiliary shaft 4.

[0042] The first connecting shaft 3 and the second connecting shaft 9 can effectively disperse the pressure from the horizontal plane, and the fixed shaft 8 can effectively withstand the pressure from the vertical plane, thus making the overall structure stable and able to withstand pressure well, avoiding the problem of mid-section breakage.

[0043] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
