Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
Referring to fig. 1 and 2, an embodiment of the present application provides a fixing device for a dowel bar 3, which includes a fixing bracket 1, and the fixing bracket is disposed in one-to-one correspondence with the dowel bar 3.
The fixing bracket 1 is used for fixing a dowel bar 3 penetrating through a web 20 positioning hole of the channel steel 2. The fixing bracket 1 is provided with a hoop 10, the hoop 10 is configured to be inserted by the dowel steel 3, two opposite sides of the hoop 10 are connected with a first clamping arm 11 and a second clamping arm 12, the first clamping arm 11 and the second clamping arm 12 are configured to penetrate through a web 20 positioning hole of the channel steel 2 at the dowel steel 3, and are respectively clamped inside two side plates 21 of the channel steel 2 after being inserted and fixed in the hoop 10, at the moment, the fixing bracket 1 is integrally clamped in a groove defined by the channel steel 2, so that the dowel steel 3 penetrates through the web 20 positioning hole of the channel steel 2 and is fixed through the fixing bracket 1, thereby preventing angular deformation during concrete pouring and being repeatedly disassembled and assembled for use.
The first clamping arm 11 comprises a first clamping section 110, wherein the first clamping section 110 and the axis of the ferrule 10 are arranged on the same plane and are parallel to the axis of the ferrule 10, so that the first clamping section 110 is attached to the inner side of the side plate 21 of the channel steel 2. The above arrangement makes the first clamping arm 11 stably clamped inside the side plate 21 of the channel steel 2, and facilitates the clamping operation of the first clamping arm 11 and the detachment of the first clamping arm 11 from the clamping position.
The first clamping section 110 is connected with the ferrule 10 through the first connecting section 111, the second connecting section 121 is of a concave structure, and two sides of the second connecting section 121 gradually shrink towards a direction away from the opening of the channel steel 2. The arrangement enables the first clamping arm 11 to stretch in the radial direction of the dowel bar 3, so that the clamping operation of the first clamping arm 11 is facilitated, and the first clamping arm 11 is separated from the clamping position.
The second clamping arm 12 comprises a second clamping section 120, and the second clamping section 120 is arranged on the same plane with the axis of the hoop 10 and is parallel to the axis of the hoop 10, so that the second clamping section 120 is attached to the inner side of the side plate 21 of the channel steel 2. The above arrangement makes the second clamping arm 12 stably clamped inside the side plate 21 of the channel steel 2, and facilitates the clamping operation of the second clamping arm 12 and the detachment of the second clamping arm 12 from the clamping position.
The second clamping section 120 is connected with the ferrule 10 through a second connecting section 121, the second connecting section 121 is in a concave structure, and two sides of the second connecting section 121 gradually shrink towards a direction away from the opening of the channel steel 2. The arrangement enables the second clamping arm 12 to extend and retract in the radial direction of the dowel 3, so that the clamping operation of the second clamping arm 12 is facilitated, and the second clamping arm 12 is separated from the clamping position.
The hoops 10 are made by bending steel bars around the outer peripheral wall of the dowel bar 3, and the inner diameter of the hoops 10 can be 2mm larger than the outer diameter of the dowel bar 3, so that the dowel bar 3 is ensured not to deviate in the concrete pouring process.
The rebars are looped around the dowel bar 3 at least two, such as two or three, turns to form the collar 10. The above arrangement makes the dowel 3 more stable after insertion into the ferrule 10.
The first clamping arm 11 and the second clamping arm 12 are made by bending the inner wall of the steel bar joint channel steel 2. Through the arrangement, the hoop 10, the first clamping arm 11 and the second clamping arm 12 are formed by stewing the same steel bar, and the formed fixing support 1 is stable in structure and convenient to process.
The steel bar is round steel, such as round steel with the diameter phi of 8 mm. The cambered surface of the round steel facilitates the insertion of the dowel bar 3 into the hoop 10, and simultaneously facilitates the clamping of the fixing support 1 in the groove defined by the channel steel 2 and the detachment from the groove.
The free ends of the first clamping arm 11 and the second clamping arm 12 are located outside the channel steel 2, so that the fixing support 1 can be further clamped in a groove defined by the channel steel 2 and disengaged from the groove.
After the dowel bar 3 fixing device is adopted, when the side die of the channel steel 2 is disassembled, firstly, the fixing support 1 is separated from the clamping part in the side die of the channel steel 2 by pressing downwards and rotating the fixing support 1, secondly, the loosened fixing support 1 is withdrawn from the dowel bar 3 through the hoop 10, the dowel bar 3 does not have angular deformation under the fixing effect of the fixing support 1 due to the arrangement, and the side die of the channel steel 2 can be withdrawn from the dowel bar 3 easily through the positioning holes of the web 20.
In summary, in the dowel bar 3 fixing device, the fixing support 1 enables the dowel bar 3 to penetrate through the web 20 locating holes of the channel steel 2 and then to be fixed through the fixing support 1, so that the dowel bar 3 is prevented from being deformed due to external influences, and the phenomenon that the dowel bar 3 cannot freely pass through the locating holes in the web 20 of the channel steel 2 and the channel steel 2 is difficult to demould is avoided.
