Description

Technical Field

[0001] The utility model relates to the field of railway bridge construction, and particularly relates to a device for fixing and preventing slurry leakage of the exposed steel bars of the T-beam transverse diaphragm. Background Art

[0002] The T-beam is a common upper structure form of railway bridges. It is designed with multiple transverse diaphragms, and generally multiple straight steel bars are designed to extend out of the concrete on the transverse diaphragms to realize the transverse connection between two adjacent T-beams. Due to the need for the installation of the T-beam formwork, the exposed steel bars of the T-beam transverse diaphragm are inserted after the formwork is closed. Therefore, they cannot be connected and fixed to other internal steel bars, resulting in the problem that they are prone to move during the vibration of the T-beam concrete, and the exposed length of the exposed steel bars of the transverse diaphragm is insufficient or the anchorage depth in the concrete is insufficient. In addition, due to the opening of the transverse diaphragm formwork, the T-beam concrete is prone to slurry leakage from the exposed steel bars during vibration, which further causes concrete waste and affects the appearance of the beam body.

[0003] To solve the above problems, the prior art generally fixedly sets positioning steel bars on the formwork, binds the exposed steel bars to the positioning steel bars, and uses foam rubber to fill the openings of the formwork to prevent slurry leakage. The prior art has the following deficiencies: (1) Affected by the high-frequency vibrator during concrete pouring, the binding of the exposed steel bars to the positioning steel bars is prone to looseness; (2) Some foam rubber will enter the formwork and needs to be cleaned after demoulding; (3) The foam rubber mainly adheres to the exposed steel bars, and when the exposed steel bars move outwards, it is easy to bring out the foam rubber tape, resulting in the foam rubber not being able to play a good role in preventing slurry leakage; (4) During demoulding, most of the foam rubber will also fall off. When the formwork is reused, it is necessary to remove the foam rubber residue and then apply foam rubber again, generating a certain amount of garbage, which is not friendly to the environment.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] A device for fixing and preventing slurry leakage of the exposed steel bar 1 of the T-beam transverse diaphragm, in combination with Figures 1-4As shown in the figure, it includes an elastic plug 4, a pressing plate 5, fixing bolts 3 and fixing nuts 6, where: The elastic plug 4, there are multiple of them, made of elastic material, can match and wrap around the periphery of the exposed steel bars 1 of the diaphragm wall, and can block the first steel bar holes 210 on the diaphragm wall formwork 2 for matching the penetration of the exposed steel bars 1 of the diaphragm wall; The pressing plate 5, which includes a pressing plate body 510 and an elastic plug fixing member 520, the pressing plate body 510 is provided with multiple second steel bar holes 512 for matching and accommodating the penetration of the exposed steel bars 1 of the diaphragm wall, and at least 4 bolt holes 511 are provided. One side surface is fixedly connected with the elastic plug fixing member 520, and the elastic plug fixing member 520 can match and clamp the elastic plug 4 and press the elastic plug 4 against the outer surface of the diaphragm wall formwork 2, so that the elastic plug 4 is fixed and blocks the first steel bar holes 210 opened on the diaphragm wall formwork 2; The fixing bolts 3, there are at least 4 of them, used to be fixed on the outer side surface of the diaphragm wall formwork 2, and can match and pass through the bolt holes 511 of the pressing plate 5; The fixing nuts 6, the number of which matches the number of the fixing bolts 3, can match and screw into the fixing bolts 3 and can be detachably fixed on the other side surface of the pressing plate body 510 away from the elastic plug fixing member 520. When the pressing plate 5 needs to be fixed, the fixing nut 6 is screwed into the fixing bolt 3 to press the pressing plate 5 tightly. In the above structure, for the number of the elastic plugs 4, it matches the number of the first steel bar holes 210 that the pressing plate 5 can block. During use, first put on the pressing plate 5, with the side having the elastic plug fixing member 520 facing the diaphragm wall formwork 2, make the exposed steel bars 1 of the diaphragm wall pass through the second steel bar holes 512 of the pressing plate, and make the fixing bolts 3 pass through the bolt holes 511 of the pressing plate 5. When the distance between the pressing plate 5 and the diaphragm wall formwork 2 is about the length of the elastic plug 4, wrap the elastic plug 4 around the exposed steel bars 1 of the diaphragm wall, and use the elastic plug fixing member 520 to clamp the elastic plug 4 and press the elastic plug 4 against the outer side surface of the diaphragm wall formwork 2. Continue to push the pressing plate 5 towards the diaphragm wall formwork 2, install and tighten the fixing nut 6 on the fixing bolt 3, the elastic plug 4 contacts the diaphragm wall formwork 2, and blocks the first steel bar holes 210 on the diaphragm wall formwork 2.

[0035] Preferably, in combination with Figure 5 As shown in the figure, the elastic plug 4 includes two symmetrically arranged elastic plug units 410. When the elastic plug units 410 are joined together, an elastic plug through hole 422 is formed in the center to match and accommodate the exposed steel bars 1 of the diaphragm wall. The above setting makes it easier to install the elastic plug 4 around the exposed steel bars 1 of the diaphragm wall. In this way, the elastic plug 4 can be installed after the pressing plate 5 is put on the exposed steel bars 1 of the diaphragm wall. And the elastic plug units 410 are symmetrically arranged, that is, of the same size, which is convenient for processing.

[0036] Preferably, the elastic plug 4 includes an elastic plug limiting portion 420 and an elastic plug clamping portion 421. The elastic plug limiting portion 420 is in the shape of a hollow cylinder, and the elastic plug clamping portion 421 is in the shape of a hollow frustum. The end with a larger outer diameter of the elastic plug clamping portion 421 is connected to the elastic plug limiting portion 420, and the outer diameter of the elastic plug limiting portion 420 is larger than the maximum outer diameter of the elastic plug clamping portion 421. The elastic plug limiting portion 420 can prevent the elastic plug fixing member 520 from directly pressing against the diaphragm formwork 2 and causing wear, and can better block the first steel bar hole 210 opened in the diaphragm formwork 2 by the elastic plug limiting portion 420. Corresponding to the elastic plug 4, there are two symmetrically arranged elastic plug units 410, and the outer shape of the elastic plug limiting portion 420 of each elastic plug unit 410 is semi-cylindrical, and the elastic plug clamping portion 421 is semi-frustrum-shaped.

[0037] Preferably, the elastic plug fixing member 520 is in the shape of a circular tube and can be inserted into the elastic plug clamping portion 421 in a matching manner, and its length is greater than or equal to the length of the elastic plug clamping portion 421. The elastic plug clamping portion 421 is designed as a hollow frustum, and the smaller end can facilitate the introduction of the elastic plug fixing member 520.

[0038] Preferably, the axis of the elastic plug fixing member 520 coincides with the axis of the second steel bar hole 512, so that the elastic plug fixing member 520 can apply force to the elastic plug 4 evenly, thereby stably blocking the first steel bar hole 210 opened in the diaphragm formwork 2.

[0039] Preferably, the minimum outer diameter of the elastic plug clamping portion 421 is smaller than the inner diameter of the elastic plug fixing member 520, and the maximum outer diameter is larger than the inner diameter of the elastic plug fixing member 520, but it can be sleeved into the elastic plug fixing member 520 in an elastically compressed state. Generally, the minimum outer diameter of the elastic plug clamping portion 421 is slightly smaller than the inner diameter of the elastic plug fixing member 520, such as 0.5 - 1 cm, to facilitate the elastic plug fixing member 520 to be sleeved into the elastic plug clamping portion 421, and the maximum outer diameter is slightly larger than the inner diameter of the elastic plug fixing member 520, such as 0.2 - 0.6 cm, so that the elastic plug clamping portion 421 can better clamp and fix the diaphragm exposed steel bars 1 and block the first steel bar hole 210 opened in the diaphragm formwork 2.

[0040] This embodiment provides a preferred elastic material for the elastic plug 4. The elastic plug 4 is made of rubber.

[0041] Preferably, second steel bar holes 512 are provided in both the upper and lower parts at both ends of the pressing plate body 510, and four fixing bolts 3 are arranged in a matching manner. The pressing plate body 510 is fixed from four corners, which can better prevent the pressing plate from warping and can apply force to each elastic plug 4 more evenly.

[0042] For the above more preferred solutions, this embodiment also provides a more specific usage method for the T-beam diaphragm exposed steel bar fixing and anti-leakage device, which specifically includes the following steps:

[0043] Step S1, after the T-beam formwork is closed and the external reinforcement bars 1 of the diaphragm wall are installed, put on the pressure plate 5, face the side with the elastic plug fixing member 520 towards the diaphragm wall formwork 2, pass the external reinforcement bars 1 of the diaphragm wall through the second steel bar hole 512 of the pressure plate 5, and pass the fixing bolt 3 through the fixing bolt hole 511 of the pressure plate 5.

[0044] Step S2, when the distance between the pressure plate 5 and the diaphragm wall formwork 2 is approximately the length of the elastic plug 4, fit the two elastic plug units 410 of the elastic plug 4 to wrap around the periphery of the external reinforcement bars 1 of the diaphragm wall, and insert the tail end of the elastic plug clamping portion 421 into the elastic plug fixing member 520.

[0045] Step S3, continue to push the pressure plate 5 towards the diaphragm wall formwork 2, install and tighten the fixing nut 6, so that the entire elastic plug clamping portion 421 enters the tubular elastic plug fixing member 520, and the elastic plug limiting portion 420 contacts the diaphragm wall formwork 2, blocking the first steel bar hole 210 on the diaphragm wall formwork 2, and completing the installation of this embodiment.

[0046] Step S4, after the T-beam concrete is poured, unscrew the fixing nut 6, pull out the pressure plate 5, and remove the elastic plug 4, then the T-beam formwork can be normally demolded, and the elastic plug 4, the pressure plate 5, and the fixing nut 6 are put away for future use.
