Description

Technical Field

[0001] This invention belongs to the field of wall shear bracing technology, specifically relating to a steel structure wall shear bracing component. Background Technology

[0002] Steel structure walls are mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. They are characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation. During the assembly of steel structure walls, scaffolding is required for support. An essential support component on the scaffolding is the scissor brace, a diagonal support resembling an X-shaped bar, which increases the load-bearing capacity of the scaffolding and facilitates the assembly and processing of the steel structure walls.

[0003] When some X-shaped bars are connected by swivel couplers, there is a lack of corresponding limiting measures at the rotation points between adjacent bars, which reduces the load-bearing capacity of the X-shaped bars. The connection points of the X-shaped bars may become loose due to relative rotation caused by heavy objects or external forces, affecting the support effect on the wall. To address this issue, we propose a steel structure wall scissor support. Summary of the Invention

[0004] The purpose of this invention is to provide a steel structure wall shear support to solve the problem mentioned in the background art that the relative rotation at the X-shaped rod rotation connection may affect the support effect on the wall.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel structure wall scissor support component, comprising a first connecting rod and a second connecting rod, wherein a scissor support structure is provided between the first connecting rod and the second connecting rod, the scissor support structure comprising two mounting ring components respectively sleeved on the first connecting rod and the second connecting rod, the mounting ring component comprising a sliding sleeve and an annular rail, the sliding sleeve being sleeved on the annular rail, a rotating mechanism being provided between two adjacent sliding sleeves, the rotating mechanism comprising a fixed sleeve and a fixed column, the outer ends of the fixed sleeve and the fixed column being respectively fixed to the surfaces of the two sliding sleeves, the inner end of the fixed column extending into the fixed sleeve and a bearing being provided between the two, a ratchet being fixedly sleeved on the inner end of the fixed sleeve, and two limiting components for limiting the ratchet being provided on the front surface of the sliding sleeve.

[0006] Preferably, the limiting component includes a rotating limiting plate, and two fixed lugs are provided on the rear surface of the sliding sleeve located in front. One end of the rotating limiting plate is movably sleeved on the mounting shaft provided between the two fixed lugs, and the other end of the rotating limiting plate is provided with a limiting hole for the teeth of the ratchet to extend into. The first connecting rod and the second connecting rod are arranged in a cross shape, and the first connecting rod is located behind the second connecting rod.

[0007] Preferably, a limiting bolt is vertically provided on the upper fixed lug, the lower end of the limiting bolt passes through the rotating limiting plate and the lower fixed lug and is exposed on the outside, a movable circular plate located on the upper surface of the rotating limiting plate is movably sleeved on the mounting shaft, and a return spring is sleeved on the mounting shaft, the upper and lower ends of the return spring being fixed to the surface of the upper fixed lug and the surface of the movable circular plate, respectively.

[0008] Preferably, limit rods are screwed onto both the upper and lower surfaces of the sliding sleeve, and the inner end of the limit rod is in contact with the surface of the mounting rail.

[0009] Preferably, two clamping components are symmetrically arranged on the surface of the mounting rail. Each clamping component includes a screw. The annular rail surface has several adjustment holes along its circumference, and the screw is screwed into one of the adjustment holes.

[0010] Preferably, a circular clamping plate is provided on the inner end surface of the screw, and a handwheel located outside the mounting rail is fixed to the outer end of the screw.

[0011] Preferably, the mounting rail includes an outer ring and an inner ring, the two of which have a T-shaped cross-section, and the sliding sleeve is fitted on the outer ring and its inner end extends to the upper and lower surfaces of the inner ring.

[0012] Preferably, two reinforcing members are symmetrically arranged between the lower surface of the mounting rail and the first connecting rod. The reinforcing members include an arc-shaped plate and a connecting plate. The two arc-shaped plates are sleeved on the first connecting rod opposite each other, and each arc-shaped plate has an extension plate at both ends. An installation screw is provided between the two opposite extension plates. The lower surface of the mounting rail is provided with two protrusions. The upper end of the connecting plate is rotatably connected to the two protrusions, and the lower end of the connecting plate is fixed to the outer surface of the arc-shaped plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention combines a first connecting rod, a second connecting rod, a mounting ring component, a rotating mechanism, and a limiting component. It can limit and reinforce the rotational connection between the first and second connecting rods without affecting their rotational connection, increasing the load-bearing strength at the connection point. This prevents abnormal rotation at the connection point from affecting the wall support effect, improving the stability and safety of the wall support. Furthermore, the angle and height between the first and second connecting rods can be adjusted according to the required wall support height, increasing their applicability.

[0015] The present invention, through the design of the clamping component, can adjust the distance between the two opposing clamping plates according to the diameter of the first connecting rod. While clamping and connecting with the first connecting rod, it can accommodate more rods of different sizes within a certain range, thus increasing the installation and use range of the mounting ring component.

[0016] The present invention increases the frictional resistance between the mounting ring component and the first connecting rod by designing a reinforcing component, thereby increasing the installation strength of the two, avoiding relative sliding between them, and increasing the stability of the first connecting rod and the mounting ring component during installation and use.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] Please see Figures 1-5 This invention provides a technical solution: a steel structure wall shear support component, including a first connecting rod 1 and a second connecting rod 2, with a shear support structure between the first connecting rod 1 and the second connecting rod 2. The shear support structure can both securely connect the first connecting rod 1 and the second connecting rod 2 and adjust the included angle between the first connecting rod 1 and the second connecting rod 2 according to the required wall support height, facilitating the formation of a suitable wall support height. The shear support structure includes two mounting ring components 3 respectively sleeved and installed on the first connecting rod 1 and the second connecting rod 2. The mounting ring components 3 and the two connecting rods are easily detached and assembled. The mounting ring components 3 include a sliding sleeve 32 and a ring rail. The sliding sleeve 32 is sleeved and installed on the ring rail. Moving the sliding sleeve 32 along the ring rail can change the position of the second connecting rod 2 on the first connecting rod 1, increasing its installation and usage range. A rotating mechanism is provided between adjacent sliding sleeves 32. 4. The rotating mechanism 4 can be used to adjust the angle formed by the first connecting rod 1 and the second connecting rod 2, and at the same time limit the connection between the two to prevent abnormal rotation and loosening at the connection. The rotating mechanism 4 includes a fixed sleeve 41 and a fixed column 43. The outer ends of the fixed sleeve 41 and the fixed column 43 are respectively fixed to the surfaces of two sliding sleeves 32. The inner end of the fixed column 43 extends into the fixed sleeve 41 and a bearing 44 is provided between the two. The rotation of the fixed column 43 can drive the front mounting ring component 3 and the second connecting rod 2 to rotate for angle adjustment. A ratchet 42 is fixedly sleeved on the inner end of the fixed sleeve 41. Two limiting components 6 are provided on the surface of the front sliding sleeve 32 to limit the ratchet 42. The position of the ratchet 42 can be limited by the limiting components 6, thereby limiting the rotational connection between the second connecting rod 2 and the first connecting rod 1, increasing the load-bearing strength and stability of the connection.

[0028] In this embodiment, preferably, the limiting member 6 includes a rotating limiting plate 62. Two fixed lugs 61 are provided on the rear surface of the sliding sleeve 32 located at the front. One end of the rotating limiting plate 62 is movably sleeved on the mounting shaft 63 located between the two fixed lugs 61. The rotating limiting plate 62 can rotate around the mounting shaft 63 to change the position of its outer end, and can also move along the mounting shaft 63 under external force. The other end of the rotating limiting plate 62 has a limiting hole 65 for the teeth of the ratchet 42 to extend into. However, the ratchet is connected through the limiting hole 65. The toothed engagement on ratchet 42 can limit the position of ratchet 42 and prevent it from rotating, thereby preventing the second link 2 connected to ratchet 42 from rotating. The first link 1 and the second link 2 are arranged in a cross shape. At the same time, the included angle between the first link 1 and the second link 2 can be adjusted according to the support height of the support on the wall, thereby adjusting the support height formed by the first link 1 and the second link 2. The first link 1 is located behind the second link 2. A limit bolt 64 is vertically installed on the fixed lug 61 located above it. 4. The lower end of the rotating limiting plate 62 and the lower fixed lug 61 are exposed on the outside. The limiting bolt 64 can limit the position of the rotating limiting plate 62 when necessary to prevent abnormal rotation of the rotating limiting plate 62. A movable circular plate located on the upper surface of the rotating limiting plate 62 is movably sleeved on the mounting shaft 63. A return spring 66 is sleeved on the mounting shaft 63. The upper and lower ends of the return spring 66 are fixed to the surface of the upper fixed lug 61 and the surface of the movable circular plate, respectively. When the rotating limiting plate 62 is subjected to external force, it moves along... When the mounting shaft 63 moves upward, it drives the movable circular plate to move upward, while the return spring 66 gradually compresses. After the limiting hole 65 disengages from the teeth on the ratchet 42, the rotating limiting plate 62 is moved outward away from the ratchet 42 without affecting the rotation of the ratchet 42. When the external force is removed, the return spring 66 returns to its elasticity, causing the rotating limiting plate 62 to move downward. This setting makes it convenient for the rotating limiting plate 62 to limit the ratchet 42, and at the same time, the two can be easily disengaged without affecting its normal rotation, thus facilitating the adjustment of the angle between the first link 1 and the second link 2.

[0029] In this embodiment, preferably, a limiting rod 33 is screwed onto both the upper and lower surfaces of the sliding sleeve 32. The position of the limiting rod 33 can be rotated and adjusted. The inner end of the limiting rod 33 contacts the surface of the mounting rail. The position of the sliding sleeve 32 can be limited and fixed by the frictional resistance and clamping force of the contact.

[0030] In summary, during use, the two mounting ring components 3 are respectively fitted onto the first connecting rod 1 and the second connecting rod 2. After the annular rail is fitted onto the first connecting rod 1, the handwheel 313 is held to drive the screw 311 to rotate and move towards the first connecting rod 1. The clamping plate 312 moves with the screw 311 until it contacts the first connecting rod 1 and presses it against the first connecting rod 1, thus achieving a tight connection between the mounting ring component 3 and the first connecting rod 1. The second connecting rod 2 is operated in the same way. When it is necessary to adjust the angle formed between the first connecting rod 1 and the second connecting rod 2, the two rotation limit plates 62 rotate in opposite directions and are located on the outside, which does not affect the rotation of the ratchet 42. This allows the second connecting rod 2 and the mounting ring component 3 on it to rotate, allowing the fixing sleeve 41 to rotate around the fixing post 43. When the second connecting rod 2 and the mounting ring component 3 on it rotate, the angle between the first connecting rod 1 and the second connecting rod 2 is adjusted. When the included angle formed by the first link 1 is appropriate, the rotating limit plate 62 is rotated relative to the first link 1, and an external force is applied to move the rotating limit plate 62 upward. The return spring 66 is gradually compressed until the limit hole 65 is above the teeth on the ratchet 42. The rotating limit plate 62 is then released and moved downward under the action of the return spring 66 to lock onto the teeth. The two rotating limit plates 62 are operated in the same way. Then, the limiting bolt 64 is used to realize the detachable connection between the rotating limit plate 62 and the fixed lug 61, limiting the position of the ratchet 42. This limits the rotational connection between the second link 2 and the first link 1. When subjected to external force, the rotational connection will not loosen due to external force, thereby increasing the support stability and support effect of the wall.

[0031] Example 2

[0032] Reference Figures 1-6 This is the second embodiment of the present invention, which differs from the previous embodiment in that...

[0033] In this embodiment, preferably, two clamping members 31 are symmetrically arranged on the surface of the mounting rail. Using the clamping members 31, the distance between the two opposing pressure plates 312 can be adjusted according to the diameter of the first connecting rod 1. While clamping and connecting with the first connecting rod 1, it can accommodate more rods of different sizes within a certain range, increasing its applicability. The clamping member 31 includes a screw 311. The annular rail surface has a number of adjustment holes 314 along its circumference. The number of adjustment holes 314 is even, which facilitates the symmetrical distribution of the two clamping members 31. The screw 311 is screwed into one of the adjustment holes 314. The position of the screw 311 can be adjusted by rotation. A circular pressure plate 312 is provided on the inner end surface of the screw 311. The pressure plate 312 is circular and can rotate with the screw 311. A handwheel 313 located on the outer side of the mounting rail is fixed to the outer end of the screw 311. The surface of the handwheel 313 has arc-shaped protrusions to increase the frictional resistance when gripping.

[0034] In this embodiment, preferably, the mounting rail includes an outer ring and an inner ring, the two of which form a T-shape in cross section. The sliding sleeve 32 is fitted on the outer ring and its inner end extends to the upper and lower surfaces of the inner ring. The advantage of the T-shape is that while slidingly connected with the sliding sleeve 32, the sliding sleeve 32 will not detach from the mounting rail.

[0035] In summary, during use, the annular rail is fitted onto the first connecting rod 1. By holding the handwheel 313, the screw 311 is rotated and moved toward the first connecting rod 1. The clamping plate 312 moves with the screw 311 until the surfaces of the two clamping plates 312 simultaneously contact the first connecting rod 1. As the screw 311 continues to rotate, the two clamping plates 312 exert a force that presses against the first connecting rod 1, increasing the frictional resistance of the contact and achieving a detachable connection between the annular rail and the first connecting rod 1. Similarly, another annular rail can be installed on the second connecting rod 2, and the clamping component 31 is used to increase the installation range of the mounting ring component 3.

[0036] Example 3

[0037] Reference Figure 7 This is the third embodiment of the present invention, which differs from the previous two embodiments in that...

[0038] In this embodiment, preferably, two reinforcing members 5 are symmetrically arranged between the lower surface of the mounting rail and the first connecting rod 1. Similarly, a reinforcing member 5 is also arranged between the second connecting rod 2 and the mounting ring member 3. The reinforcing members 5 increase the frictional resistance between the mounting ring member 3 and the first connecting rod 1, thereby increasing their installation strength. The reinforcing member 5 includes an arc-shaped plate 52 and a connecting plate 53. The two arc-shaped plates 52 are fitted onto the first connecting rod 1, and the two arc-shaped plates 52 can relatively clamp the first connecting rod 1, increasing the contact frictional force. Both ends of the arc-shaped plates 52 are provided with extension plates 55, which are relatively... A mounting screw 54 is provided between the two extension plates 55 to achieve relative clamping of the two arc plates 52. Two protrusions 51 are provided on the lower surface of the mounting rail. The upper end of the connecting plate 53 is rotatably connected to the two protrusions 51. A rotating shaft is provided between the two to facilitate the rotation of the connecting plate 53 to drive the arc plates 52 to rotate and change the distance between the two arc plates 52. The lower end of the connecting plate 53 is fixed to the outer surface of the arc plate 52. The connecting plate 53 can connect the arc plate 52 and the ring rail. The position of the arc plate 52 is fixed, which can fix the position of the ring rail, thereby increasing the installation strength of the mounting ring component 3 and the first connecting rod 1.

[0039] In summary, during use, as the mounting ring component 3 is fitted onto the first connecting rod 1, the two connecting plates 53 can be rotated toward the first connecting rod 1. The connecting plates 53 rotate around the pivot, causing the two arc-shaped plates 52 fixed at their lower ends to move relative to each other until the inner surfaces of the two arc-shaped plates 52 are in contact with the first connecting rod 1. Then, the two extension plates 55 at the opposite ends of the arc-shaped plates 52 are connected and fixed with the mounting screws 54. As the mounting screws 54 are rotated, the two arc-shaped plates 52 and the extension plates 55 can move relative to each other and clamp, thereby increasing the frictional resistance between the arc-shaped plates 52 and the first connecting rod 1 and the pressing force of the arc-shaped plates 52 on the first connecting rod 1, realizing the tight connection between the two, thereby increasing the installation strength and usage stability of the mounting ring component 3 and the first connecting rod 1.

[0040] Example 4

[0041] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0042] In use, the mounting ring component 3 is detachably mounted on the first connecting rod 1 or the second connecting rod 2 via the clamping component 31. The ring rail is further reinforced with the first connecting rod 1 by the reinforcing component 5, increasing the installation strength and stability of the mounting ring component 3 and the first connecting rod 1. According to the wall support requirements of the steel structure, the included angle between the first connecting rod 1 and the second connecting rod 2 is adjusted by the rotating mechanism 4, thereby changing the support height of the two ends on the wall. When the height is appropriate, the ratchet 42 in the rotating mechanism 4 is limited and fixed by the limiting component 6, thereby achieving the limiting at the first connecting rod 1 and the second connecting rod 2, increasing the load-bearing strength at the rotating connection, preventing abnormal rotation at the connection due to external force, increasing the stability of the wall support for the steel structure and increasing the load-bearing strength of both.
