Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to an I-beam anti-dumping device used in construction sites. Background Art
[0002] In modern building structures, steel structures are increasingly used. During the construction process, in order to ensure the installation progress, a yard needs to be set up on site to store a large number of finished components. For the storage of steel structure components, it is necessary to use a vertical placement method for three reasons: first, it saves space and is convenient for material distribution and hoisting; second, it maintains the original stress state of the steel beam; and third, it is convenient for the preparation of security measures. However, the height-to-width ratio of most H-shaped steel beams is too large, and there is a risk of tipping over, which can easily cause harm to personnel. At present, the industry's practice is usually to use a reinforcement form with triangular supports, but the current triangular support point is usually located near the lower flange of the I-beam. This fixing method applies a stress to the component locally when the I-beam is subjected to lateral force, so that the local stress causes damage to the structure of the component itself. Utility Model Content
[0003] The main purpose of the utility model is to provide an I-beam anti-dumping device for a construction site, so as to solve the problem that the triangular support causes local damage to the I-beam component.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is to provide an I-beam anti-dumping device for construction sites, including: a first fixing part, a second fixing part, a telescopic part and a supporting part; the first fixing part and the second fixing part are arranged opposite to each other, the first fixing part and the second fixing part are connected by the telescopic part, and there is an accommodating space between the first fixing part and the second fixing part, and the contour of the accommodating space matches the outer contour of the upper flange of the I-beam; the supporting part is respectively arranged on the first fixing part and the second fixing part.
[0005] In a preferred embodiment, the first fixing part includes: a waist support plate for abutting against the waist plate on one side of the I-beam; an upper flange pressure plate for abutting against the top of the upper flange of the restricted I-beam; an upper flange top plate for abutting against the bottom of the upper flange of the restricted I-beam; an upper flange top plate for abutting against the bottom of the upper flange of the restricted I-beam; a mounting plate for installing and fixing the telescopic part; the second fixing part includes: a waist support plate for abutting against the waist plate on the other side of the I-beam; an upper flange pressure plate for abutting against the top of the upper flange of the restricted I-beam; an upper flange top plate for abutting against the bottom of the upper flange of the restricted I-beam; an upper flange top plate for abutting against the bottom of the upper flange of the restricted I-beam; a mounting plate for installing and fixing the telescopic part.
[0006] In a preferred solution, the telescopic part is a screw assembly, the fixed end of the screw assembly is located on the mounting plate of the first fixed part, and the driving end of the screw assembly is arranged on the mounting plate of the second fixed part.

[0008] In a preferred solution, the support portion is a telescopic bracket.
[0009] Beneficial effects of the utility model: The present application fixes the upper flange of the I-beam component by the first fixing part and the second fixing part. When the I-beam component is overturned due to lateral force, the fixing method of the utility model is less harmful to the I-beam component than the traditional fixing method of the triangular fixing position being biased downward. And because the widths of the upper flanges of different types of I-beams are different, in order to adapt to more types of I-beams, the utility model uses a telescopic part to form an adjustable structure with two fixing parts.

DETAILED DESCRIPTION
[0015] like Figures 1 to 3As shown in the figure, the I-beam anti-tipping device for the construction site includes: a first fixing part 1a, a second fixing part 1b, a telescopic part 2, and a supporting part 3; the first fixing part 1a and the second fixing part 1b are arranged opposite to each other, and the first fixing part 1a and the second fixing part 1b are connected by the telescopic part 2. There is an accommodating space between the first fixing part 1a and the second fixing part 1b, and the contour of the accommodating space matches the outer contour of the upper flange 51 of the I-beam 5; the supporting part 3 is respectively arranged on the first fixing part 1a and the second fixing part 1b.
[0016] In this embodiment, the upper flange 51 of the I-beam 5 component is fixed by the first fixing part 1a and the second fixing part 1b. When the I-beam 5 component is toppled due to a lateral force, the fixing method of the present invention causes less damage to the I-beam 5 component compared with the traditional fixing method with a lower triangular fixing position. And because the widths of the upper flanges 51 of different models of I-beams 5 are different, in order to adapt to more models of I-beams 5, the present invention uses the telescopic part 2 to form an adjustable structure between the two fixing parts. Since the present invention adopts a through design between the two fixing parts, different numbers of the present invention can be installed for I-beam 5 components of different lengths. The specific number can be determined by the user according to their actual usage needs, and the present application does not limit it.
[0017] As Figure 3 shown, in one specific embodiment, the first fixing part 1a includes: a web support plate for abutting against one side web 52 of the I-beam 5; an upper flange pressing plate 12 for abutting against and restricting the top of the upper flange 51 of the I-beam 5; an upper flange top plate 13 for abutting against and restricting the bottom of the upper flange 51 of the I-beam 5; an upper flange top plate 13 for abutting against and restricting the bottom of the upper flange 51 of the I-beam 5; a mounting plate 14 for mounting and fixing the telescopic part 2; the second fixing part 1b includes: a web support plate for abutting against the other side web 52 of the I-beam 5; an upper flange pressing plate 12 for abutting against and restricting the top of the upper flange 51 of the I-beam 5; an upper flange top plate 13 for abutting against and restricting the bottom of the upper flange 51 of the I-beam 5; an upper flange top plate 13 for abutting against and restricting the bottom of the upper flange 51 of the I-beam 5; a mounting plate 14 for mounting and fixing the telescopic part 2. In this design, the web support plate is located at the lower part of the fixing part and is a vertically arranged plate-like structure. The two fixing parts jointly clamp the web 52 of the I-beam 5 in the middle to prevent the I-beam 5 component from tipping to both sides. The upper flange pressing plate 12 is in an "丄" shape, and the lower end surface of the upper flange pressing plate 12 is a plate-like surface. The lower end surface of the upper flange pressing plate 12 and the upper end surface of the upper flange top plate 13 jointly form an accommodating space for the upper flange 51 of the I-beam 5 component. Generally, the thicknesses of the upper flanges 51 of different models of I-beams 5 do not differ much, so this accommodating space does not need to be adjustable.
[0018] In one specific embodiment, the telescopic part 2 is a screw assembly, the fixed end 21 of the screw assembly is located on the mounting plate 14 of the first fixed part 1a, and the driving end 22 of the screw assembly is arranged on the mounting plate 14 of the second fixed part 1b. In this design, the screw assembly can be adjusted by manually twisting the driving end 22, or an electrically driven motor can be set as the driving end 22 for driving. The user can decide according to his actual use, and this application does not limit it.
[0019] In one specific embodiment, the angle between the support portion 3 and the first fixing portion 1a is adjustable, and the support portion 3 is connected to the first fixing portion 1a through a locking device 4; the angle between the support portion 3 and the second fixing portion 1b is adjustable, and the support portion 3 is connected to the second fixing portion 1b through a locking device 4. In this design, the angle of the support portion 3 is different in the face of different placement conditions, so the angle between the support portion 3 and the fixing portion needs to be adjustable, and after the adjustment is completed, it can be locked and fixed through the locking device 4. This application adopts tightening fixation, which belongs to the prior art and will not be described in detail in this application.
[0020] In one of the specific embodiments, the support part 3 is a telescopic bracket. In this design, since the heights of the I-beam 5 components of different models are different, the length of the support part 3 can also be adjusted in the face of I-beam 5 components of different heights. The application adopts a telescopic bracket to adjust, which is similar to the telescopic method of a camera tripod. This technology belongs to the prior art and this application does not elaborate too much.
[0021] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
