Description

Technical Field

[0001] The invention relates to the technical field of steel structure trusses, in particular to a steel structure truss structure. Background Art

[0002] In various engineering structures, a special type of rigid system is widely used. They are structures with unchanged geometric shape formed by some short and straight rigid bars connected to each other at the ends (riveted or welded). When the connection between the steel bars can be approximately regarded as a hinge constraint, this type of bar system structure is called a truss. For example, bridges, roof trusses, TV towers and crane racks. When designing a truss, try to make the external load concentrated on the connection of the steel bars to ensure that the steel bars are mainly subjected to tension or pressure.

[0003] Trusses are widely used in the field of construction. The most common use is in roof structures, in which trusses act as supports for the roof structures. Considering the stability, they are mostly presented and used in triangular structures. Of course, the triangular structure mentioned here has two meanings. The first is that the overall frame structure is triangular, such as the prior art: CN113494142 A, a steel structure truss; the other is that the overall structure is straight, and the small internal structure is triangular, such as the prior art: CN113719028A, a spliced ​​steel structure truss.

[0004] The above-mentioned prior art, whether it is the first or the second technical solution, when used in the building structure, will bear and support the weight of the roof structure. With the continuous increase of the use time, the truss will sink and bend under the pressure for a long time, especially the second straight steel structure truss. The prior art CN 113494142 A is a steel structure truss. The technical solution mainly includes two right-angle plates, the two right-angle plates are horizontally arranged, the two right-angle plates are connected by multiple steel rods, and the multiple steel rods are connected at the ends in turn; the steel rods at the two ends are vertically arranged, and an arc plate is connected between the two steel rods. The top of the arc plate is provided with multiple sliding grooves, and the sliding grooves are penetrated. The tension rod designed therein can play a pulling role in the whole technical solution, but it is mainly a rigid structure. When pulling the bottom structure in the truss, it is quite strict. When it is affected by the external environment, such as when the roof structure is impacted or windy and moves, it will directly act on the bottom structure through the tension rod, and due to the small contact area, the impact on the bottom structure of the truss is also particularly obvious.

[0005] Therefore, we propose a steel structure truss to solve the defects and problems in the above technical solutions. Summary of the invention

[0006] The object of the present invention is to provide a steel structure truss structure to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions: A steel truss structure comprises a crossbeam frame and a support beam fixedly welded to the top of the crossbeam frame, a moving block is mounted on the outer ring of the crossbeam frame, an ear plate structure is fixedly welded to the top of the moving block, a threaded column is installed in the ear plate structure, an insertion port is provided at the top of the support beam, a fixing bolt is installed through the inner cavity of the insertion port, a pull ring is mounted on the outer ring of the fixing bolt, a steel wire rope is bolted to the pull ring, a movable sleeve is mounted on the bottom of the outer ring of the steel wire rope, a threaded hole is provided at the bottom of the movable sleeve, and a tensioning spring is mounted on the outer ring of the steel wire rope.

[0008] Preferably, a non-slip rubber pad is fixedly bonded to the bottom of the inner side wall of the moving block, and a small pointed cone is fixedly welded to the I-shaped recessed area of ​​the moving block.

[0009] Preferably, a convex-shaped hole is provided in the upper middle portion of the movable sleeve, and the tension spring is located in the inner cavity of the convex-shaped hole.

[0010] Preferably, a limiting disk is fixedly welded to the bottom end of the steel wire rope, and the top of the limiting disk is in compression contact with the bottom of the tension spring.

[0011] Preferably, the fixing bolt is inserted from one side of the support beam, passes through the plug interface and then comes out from the other side of the support beam, and the diameter of the fixing bolt is smaller than the inner diameter of the hole into which it is plugged, and the fixing bolt is fixed by locking with a nut.

[0012] Preferably, a transverse axis is installed through the side of the ear plate structure, and the transverse axis passes through the two ear plate structures and the threaded column in sequence, and is locked and fixed by a nut.

[0013] Preferably, the moving block is a two-half structure and is butt-mounted by bolt fasteners. The top of the inner wall of the moving block is a rough surface and contacts the surface of the beam frame, and the tip of the small cone also contacts the outer surface of the beam frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The steel truss structure, through the design and use of moving blocks, wire ropes, movable sleeves and threaded columns, when the truss is used and installed, the pulling force of the beam frame acts directly on the roof structure, which is more effective when pulling and plasticizing the truss.

[0015] 2. The steel truss structure, through the design and use of moving blocks, steel wire ropes, movable sleeves, threaded columns and tension springs, can firstly change and select the pulling position in real time according to the different sizes of truss structures and the assembled roof structures, that is, the force point can be changed. Secondly, when pulling the truss, it can also effectively solve the problem of the influence of external factors on the truss structure; 3. The steel truss structure, through the design and use of moving blocks, small cones and rough inner walls, can directly push the moving blocks back and forth before installation or during later maintenance to remove sticky and rusty materials on the beam frame, which increases the aesthetics of the truss and reduces the risk of rust in later use.

[0016] 4. The steel truss structure can adjust the pulling force angle of the truss through the design and use of moving blocks, steel wire ropes, movable sleeves, threaded columns and tension springs during the later use of the truss. While changing the pulling force angle, the size of the pulling force can be changed by changing the compression state of the tension spring. That is, if the crossbeam is bent, real-time adjustments can be made to prevent subsequent deformation. At the same time, the pulling force can be increased to slowly and appropriately correct the full angle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0020] The present invention provides a technical solution for a steel truss structure: Embodiment 1:

[0021] like Figure 1 As shown, the truss mainly includes a crossbeam frame 1 and a support beam 2 fixedly welded to the top of the crossbeam frame 1 .

[0022] A moving block 3 is sleeved on the outer ring of the crossbeam frame 1 , a lug plate structure 4 is fixedly welded to the top of the moving block 3 , and a threaded column 5 is installed in the inner space of the lug plate structure 4 .

[0023] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a plug interface 6 for clamping the roof is provided at the top of the support beam 2, a fixing bolt 7 is connected through the inner cavity of the plug interface 6, a pull ring 8 is mounted on the outer ring of the fixing bolt 7, a steel wire rope 9 is bolted to the bottom of the pull ring 8, a movable sleeve 10 is mounted on the outer ring of the steel wire rope 9, a threaded hole 11 matching the threaded column 5 is provided at the bottom of the movable sleeve 10, a convex hole 15 is drilled in the middle of the upper middle position of the movable sleeve 10, a limiting disk 16 is fixedly welded to the bottom end of the steel wire rope 9, and a tensioning spring 17 is mounted on the outer ring of the steel wire rope 9 located in the inner cavity of the convex hole 15.

[0024] The moving block 3 is a two-half structure, and is assembled by bolt fasteners. The two-stage moving block 3 design is adopted here mainly to improve the disassembly and assembly performance of the moving block 3, because the entire truss structure is in a triangular state, and the two ends of the crossbeam frame 1 are closed by the support beam 2, so the spliced ​​moving block 3 design is adopted.

[0025] Among them, the bottom of the inner wall of the moving block 3 is fixedly bonded with an anti-skid rubber pad 12, and a small pointed cone 13 is fixedly welded on the inner wall of the I-shaped recessed position of the moving block 3. The main function of the anti-skid rubber pad 12 is to increase the friction between the moving block 3 and the crossbeam frame 1, and similarly, the main function of the small pointed cone 13 is also to increase the friction between the moving block 3 and the crossbeam frame 1.

[0026] Among them, a transverse shaft 14 is installed through the side of the ear plate structure 4, and a threaded structure is set at both ends of the transverse shaft 14, and the transverse shaft 14 is in a state of passing through the threaded column 5. When the entire threaded column 5 is installed with the transverse shaft 14 in conjunction with the nut structure, the threaded column 5 can rotate at any angle with the transverse shaft 14 as the center.

[0027] In this embodiment, the first step is the installation process, in which the two ends of each truss structure are directly overlapped on the building wall, and then fastened with fasteners. When the truss is installed, the roof structure can be directly laid on the truss structure, that is, laid on the top of the support beam 2, and the raised structure provided on the roof structure is inserted into the plug-in port 6. A groove space for accommodating the pull ring 8 needs to be reserved on the raised structure here.

[0028] After that, the movable block 3 is moved to the appropriate position along the axial direction of the beam frame 1, and then the movable sleeve 10 is pulled to the position of the movable block 3, and the threaded column 5 is turned so that it can be inserted into the inner cavity of the movable sleeve 10 along the radial direction of the wire rope 9, and then the movable sleeve 10 is continuously rotated to allow it to be gradually threadedly connected with the threaded column 5. When pulling the movable sleeve 10 and screwing the movable sleeve 10 into the threaded column 5, the tensioning spring 17 is gradually compressed. After the movable sleeve 10 is installed, the tensioning spring 17 applies a downward pulling force to the wire rope 9 through the interaction force between the inner wall of the convex hole 15 and the limit plate 16. Therefore, after the movable sleeve 10 is installed, the wire rope 9 always pulls the beam frame 1. This pulling action is similar to the effect of the steel cable on the bridge, so as to ensure the stability of the beam frame 1 and prevent the beam frame 1 from being easily deformed during long-term use.

[0029] The roof structure is supported by the building walls at both ends, and the protruding structure of the roof structure is locked by the fixing bolt 7 and the nut structure. Therefore, the upper end force point of the pulling force generated by the steel wire rope 9 is on the roof structure, not on the truss, and then the pulling and traction action of the crossbeam frame 1 can be realized.

[0030] Among them, when the moving block 3 is pulled by the wire rope 9, the anti-slip rubber pad 12 thereon will be squeezed and deformed, thereby increasing the friction between the moving block 3 and the beam frame 1. At the same time, the tip position of the small pointed cone 13 is also squeezed and pierced on the beam frame 1, which also increases the friction between the moving block 3 and the beam frame 1.

[0031] Embodiment 2: like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a plug interface 6 for clamping the roof is provided at the top of the support beam 2, a fixing bolt 7 is connected through the inner cavity of the plug interface 6, a pull ring 8 is mounted on the outer ring of the fixing bolt 7, a steel wire rope 9 is bolted to the bottom of the pull ring 8, a movable sleeve 10 is mounted on the outer ring of the steel wire rope 9, a threaded hole 11 matching the threaded column 5 is provided at the bottom of the movable sleeve 10, a convex hole 15 is drilled in the middle of the upper middle position of the movable sleeve 10, and a limiting disk 16 is fixedly welded to the bottom end of the steel wire rope 9, a tensioning spring 17 is mounted on the outer ring of the steel wire rope 9 located in the inner cavity of the convex hole 15, and the upper and lower ends of the tensioning spring 17 are respectively against the inner wall of the movable sleeve 10 and the upper surface of the limiting disk 16.

[0032] In this embodiment, based on the first embodiment, when the steel wire rope 9 pulls the crossbeam frame 1, the tension spring 17 is in a compressed state. When the roof structure is installed and is affected by external factors, such as the effect of wind, and impact vibration occurs, the steel wire rope 9 cooperates with the tension spring 17 to buffer and unload the external force to a certain extent. The outer side of the tension spring 17 here is in compression contact with the inner wall of the convex hole 15, which can serve as a damper for the tension spring 17 to avoid excessive vibration. The use of the steel wire rope 9 in conjunction with the tension spring 17 effectively relieves and unloads the external force, effectively solving the problem that the rigid connection between the roof steel structure and the truss is easily affected by vibration and impact, affecting the safety of the roof structure, truss and building wall.

[0033] The diameter of the fixing bolt 7 is smaller than the diameter of each hole in which it is inserted and installed, so that when it is used later, the roof structure can have a buffer space to provide conditions for force unloading and buffering.

[0034] Embodiment 3: A moving block 3 is mounted on the outer ring of the crossbeam frame 1, and a small pointed cone 13 is fixedly welded on the inner wall of the I-shaped recessed position of the moving block 3. The top position of the inner wall of the moving block 3 is a rough surface and contacts the outer wall of the crossbeam frame 1, and the top of the small pointed cone 13 contacts the outer wall of the crossbeam frame 1.

[0035] In this embodiment, the rough surface of the inner wall of the moving block 3, the small pointed cone 13 and the anti-slip rubber pad 12 mainly function to increase the friction with the crossbeam frame 1 to prevent the moving block 3 from sliding when the wire rope 9 is pulled; secondly, before installation, the moving block 3 can be directly pushed back and forth. Through the use of its rough surface and the small pointed cone 13, the rust on the crossbeam frame 1 can be removed to increase the aesthetics of the truss and the anti-rust function in the later stage.

[0036] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
