Description

[0001] The present invention relates to the technical field of building auxiliary equipment, in particular to a temporary fixing device for a cantilevered steel beam. Background Art

[0002] Cantilevered steel beams are commonly used load-bearing components in construction, and their fixing method is directly related to construction safety and structural stability. Cantilevered steel beams are often used in temporary facilities such as external scaffolding and unloading platforms. Temporary fixing of cantilevered steel beams refers to a transitional fixation measure taken before the formal fixing (such as bolt anchoring and welding) is completed to ensure the stability and reliability of the beam during installation.

[0019] The present invention uses the tip of the steel beam platform away from the building wall as the fulcrum of the steel beam frame to form a lever-like structure of the steel beam frame. When the end of the steel beam frame away from the building wall droops, the steel beam frame applies downward pressure to the oblique support rod. The oblique support rod uses the auxiliary support rod positioning hook to hook the distribution block, positioning arc plate and column, so that the pressure plate presses down the end of the steel beam frame close to the building wall, thereby using the steel beam frame itself as a lever to prevent the steel beam frame from sagging and bending, and to avoid weakening the cross-sectional area of ​​the extension block and changing the stress distribution when supporting the steel beam frame, resulting in local stress concentration, causing structural cracking or instability.

[0020] Furthermore, lateral support rods and insertion rods are used to apply lateral support force to the steel beam frame to prevent the steel beam frame from deflecting when subjected to lateral wind. At the same time, when the steel beam frame is subjected to wind force and exerts pressure on the support plate, the support plate and the insertion rod produce relative displacement, and the insertion rod pushes the first piston to extend the push plate, applying a force in the opposite direction to the wind force to the steel beam frame to offset the lateral wind force.

[0021] Furthermore, by controlling the equidistant distribution of multiple distribution blocks through the folding frame, the steel beam frame is distributed more evenly, so that the downward pressure exerted by the pressure plate on each steel beam frame is the same, thereby ensuring that the lateral support force of the lateral support rods and the insertion rods on the support plates at different positions is the same.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0034] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0037] Example 1: This example proposes a temporary fixing device for cantilevered steel beams, such as Figure 1 As shown, it is applied to a building wall 1 and a steel beam frame 5, including a side panel 2, a steel beam platform 4 for erecting the steel beam frame 5 is fixedly installed on the side of the side panel 2, and the side of the side panel 2 is fixedly installed on the side of the building wall 1 by bolts.

[0038] like Figure 2 and Figure 3 As shown, a support mechanism 6 is provided below the steel beam frame 5. The support mechanism 6 includes an oblique support rod 62. A secondary support rod 65 is fixedly mounted in the middle of the oblique support rod 62. A support plate 63 for supporting the steel beam frame 5 is fixedly mounted at the top of the oblique support rod 62. A lower positioning block 61 is fixedly mounted at the bottom of the oblique support rod 62. The lower positioning block 61 is engaged with the extension block 3. A groove is formed at the top of the extension block 3, and a protrusion is fixedly mounted at the bottom of the lower positioning block 61 to be inserted into the groove.

[0039] A lateral block 64 is fixed to the top of the support plate 63. The steel beam frame 5 is an I-beam. Two lateral blocks 64 are symmetrically located on the top of the support plate 63. The diagonal support rod 62 is tilted at a 45-degree angle. The lower positioning block 61 secures the bottom end of the diagonal support rod 62 by means of a groove and a protrusion, thereby supporting the steel beam frame 5.

[0040] A lateral block 64 is fixedly installed on the top of the support plate 63. The steel beam frame 5 adopts an I-beam. Two lateral blocks 64 are provided and symmetrically distributed on the top of the support plate 63. The two lateral blocks 64 and the support plate 63 form a U-shaped structure. An L-shaped embedding groove is provided on the top of the support plate 63, and the lateral blocks 64 slide along the embedding groove.

[0041] The left and right positions of the steel beam frame 5 are fixed by two lateral blocks 64. Since an L-shaped embedding groove is provided on the top of the support plate 63, the lateral block 64 can be separated from the steel beam frame 5 by sliding in the embedding groove and sliding in the direction away from the steel beam frame 5, thereby removing the lateral block 64 and the support plate 63 as a whole.

[0042] like Figure 3 and Figure 4 As shown, the end of the auxiliary support rod 65 is fixedly installed with a block 66 that rests on the inclined surface of the steel beam platform 4, and a circular ring 67 is rotatably connected on both sides of the block 66. A positioning hook 68 is fixedly installed on the outer arc surface of the circular ring 67. A cylinder 612 is fixedly installed on both sides of the steel beam platform 4. A positioning fastener for fixing the cylinder 612 is provided on the top of the steel beam frame 5. The inner arc surface of the positioning hook 68 is in contact with the positioning fastener. The steel beam platform 4 adopts an isosceles right triangle structure, and the auxiliary support rod 65 is perpendicular to the inclined surface of the steel beam platform 4.

[0043] The positioning fastener includes a pressure plate 69, and the internal sliding connection of the pressure plate 69 is a distribution block 610. The bottom of the distribution block 610 is provided with a snap-in socket for a snap cylinder 612. The side of the distribution block 610 is fixedly installed with a positioning arc plate 611. The positioning arc plate 611 adopts a semi-circular ring structure. The inner arc surface of the positioning arc plate 611 contacts the cylinder 612, and the inner surface of the positioning hook 68 contacts the outer arc surface of the positioning arc plate 611.

[0044] The pressure plate 69 is pressed on the top of the steel beam frame 5 and close to the end position, and the opening at the bottom of the distribution block 610 is used to buckle it on the cylinder 612. Then, the positioning hook 68 is used to buckle the positioning arc plate 611 and the cylinder 612 to fix the position of the oblique support rod 62 and the auxiliary support rod 65. The auxiliary support rod 65 is perpendicular to the oblique support rod 62. The steel beam platform 4 adopts an isosceles right triangle structure, and the auxiliary support rod 65 is perpendicular to the inclined surface of the steel beam platform 4.

[0045] When the end of the steel beam frame 5 droops away from the building wall 1, the auxiliary support rod 65 is subjected to force and applies force along the direction of the auxiliary support rod 65 to the pressure plate 69 and the positioning arc plate 611, so that the pressure plate 69 applies downward pressure to the end of the steel beam frame 5 close to the building wall 1. The tip position of the steel beam platform 4 away from the building wall 1 serves as the fulcrum of the steel beam frame 5, and the steel beam frame 5 forms a lever structure, thereby clamping the steel beam frame 5 with the pressure plate 69 and the steel beam platform 4 to fix the steel beam frame 5, and the pressure plate 69 presses on the top of multiple steel beam frames 5, and the pressure plate 69 connects multiple steel beam frames 5 together.

[0046] Since it is a temporary fixing device, the distribution block 610 and the positioning arc plate 611 are fixed to the top of the cylinder 612 by rotating the ring 67 and the positioning hook 68. They can be separated by rotating the ring 67, which is easy to disassemble.

[0047] In this embodiment, the tip of the steel beam platform 4 away from the building wall 1 serves as the fulcrum of the steel beam frame 5, so that the steel beam frame 5 forms a lever-like structure. When the end of the steel beam frame 5 away from the building wall 1 droops, the steel beam frame 5 applies downward pressure to the oblique support rod 62. The oblique support rod 62 uses the auxiliary support rod 65 positioning hook 68 to hook the distribution block 610, the positioning arc plate 611 and the cylinder 612, so that the pressure plate 69 presses down the end of the steel beam frame 5 close to the building wall 1, thereby using the steel beam frame 5 itself as a lever to prevent the steel beam frame 5 from sagging and bending, and to avoid weakening the cross-sectional area of ​​the extension block 3 and changing the stress distribution when supporting the steel beam frame 5, resulting in local stress concentration, causing structural cracking or instability.

[0048] Example 2, based on Example 1, this example proposes a temporary fixing device for cantilevered steel beams, such as Figure 1 and Figure 5 As shown, a wind force offsetting mechanism 7 is provided inside the support plate 63, and the wind force offsetting mechanism 7 includes a lateral support rod 71. The lateral support rod 71 adopts a V-shaped structure. The tip of the lateral support rod 71 is fixedly connected to the pressure plate 69 by multiple bolts. The other end of the lateral support rod 71 is fixedly connected to the insertion rod 72. The end of the insertion rod 72 is inserted into the interior of the support plate 63. A hydraulic mechanism is provided inside the support plate 63. The other end of the hydraulic mechanism is provided with a push plate 78. The push plate 78 slides inside the lateral block 64.

[0049] The steel beam 5 is laterally supported by the lateral support rods 71 ​​and the insertion rods 72 to prevent the steel beam 5 from bending when subjected to lateral wind forces. When the steel beam 5 is displaced by wind, the steel beam 5 and the support plate 63 move to the right, causing the insertion rod 72 on the right side of the support plate 63 to slide into the support plate 63, causing the hydraulic mechanism to extend the push plate 78, exerting a force on the steel beam 5 in the opposite direction of the wind force to offset the lateral wind force.

[0050] like Figure 6As shown, the hydraulic mechanism includes a first hydraulic oil tank 74, which is opened inside the support plate 63, and a first piston 73 is slidably connected inside the first hydraulic oil tank 74. The end of the insertion rod 72 is in contact with the first piston 73, and a second hydraulic oil tank 76 is opened inside the lateral block 64. The second hydraulic oil tank 76 is slidably connected inside the second piston 77, and an intermediate rod is fixedly installed between the second piston 77 and the push plate 78. The first hydraulic oil tank 74 is connected to the second hydraulic oil tank 76 through a hydraulic pipe 75. The push plate 78 adopts an I-shaped structure, and the push plates 78 sliding inside the two lateral blocks 64 clamp the steel beam frame 5.

[0051] The steel beam frame 5 is deflected by the wind force, and the insertion rod 72 and the support plate 63 produce relative displacement. When the insertion rod 72 slides into the support plate 63 and pushes the first hydraulic oil tank 74 to slide, the insertion rod 72 pushes the first piston 73 to slide and pushes the hydraulic oil in the first hydraulic oil tank 74 into the second hydraulic oil tank 76, so that the second piston 77 pushes out the push plate 78, and the push plate 78 applies a reaction force to the steel beam frame 5.

[0052] In this embodiment, lateral support rods 71 ​​and insertion rods 72 are used to apply lateral support force to the steel beam frame 5 to prevent the steel beam frame 5 from deflecting when subjected to lateral wind. At the same time, when the steel beam frame 5 is subjected to wind force and exerts pressure on the support plate 63, the support plate 63 and the insertion rod 72 produce relative displacement, and the insertion rod 72 pushes the first piston 73 to extend the push plate 78, applying a force in the opposite direction of the wind force to the steel beam frame 5 to offset the lateral wind force.

[0053] Example 3, based on the above-mentioned Example 1 or Example 2, this example proposes a temporary fixing device for cantilevered steel beams, such as Figure 7 and Figure 8 As shown, the interior of the pressing plate 69 is provided with an equidistant distribution mechanism 8, which includes a folding frame 81. A plurality of distribution blocks 610 are provided, and two adjacent distribution blocks 610 are connected to each other through the folding frame 81. The folding frame 81 is used to control the equidistant distribution of the plurality of distribution blocks 610, so that the distribution of the steel beam frame 5 is more uniform.

[0054] like Figure 9 As shown, the internal thread of the distribution block 610 is connected to a screw 82 perpendicular to the ground. The top of the screw 82 is rotatably connected to a tooth plate 84 that is slidably connected to the distribution block 610. A plurality of positioning teeth 83 arranged along a straight line are fixedly mounted on the inner wall of the pressure plate 69, directly above the distribution block 610. The positioning teeth 83 engage with the tooth plate 84. By rotating the screw 82, the tooth plate 84 is lifted upward, and the tooth plate 84 engages with the positioning teeth 83 to fix the position of the distribution block 610.

[0055] In this embodiment, the folding frame 81 is used to control the equal distribution of multiple distribution blocks 610, so that the steel beam frame 5 is distributed more evenly, so that the downward pressure applied by the pressure plate 69 to each steel beam frame 5 is the same, thereby ensuring that the lateral support rods 71 ​​and the insertion rods 72 have the same lateral support force on the support plates 63 at different positions.

[0056] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
