[0002] A T-shaped beam refers to a beam with a T-shaped cross-section. The two protruding parts on both sides are called flanges, and the middle part is called the beam rib (or web). Its load-bearing structure is composed of the upper flange of reinforced concrete and the beam rib combined. The compression zone of the T-shaped beam cross-section uses pressure-resistant concrete to make the flange plate and also serves as the bridge deck, and the tension zone uses steel bars or prestressed steel bars to bear the tension; the structure of the T-shaped beam can save concrete, reduce the self-weight of the component, improve the spanning ability, and is more and more used in bridge construction.
[0003] In actual construction, since the two ends of the steel bars to be tied should extend out of the side wall of the flange plate during construction, there will be gaps between adjacent formworks when installing the formworks. In this way, concrete slurry will seep out from the gaps during pouring, resulting in waste of resources. Moreover, the exuded concrete slurry falls on the outer surface of the formwork and is not conducive to subsequent formwork removal after coagulation, causing inconvenience to construction.
[0004] Therefore, it is necessary to provide a new EPE anti-leakage device for the flange plate of a T-shaped beam to solve the above technical problems. Content of the Utility Model
[0005] To solve the above technical problems, the utility model provides an EPE anti-leakage device for the flange plate of a T-shaped beam, which can close the gaps between the comb plates and effectively reduce various quality problems caused by the loss of concrete slurry and aggregate during pouring.

[0021] In the specific implementation process, such as Figure 1 Figure 2 、 Figure 3 and Figure 4As shown in the figure, the positioning structure 2 further includes a buckle 21 and a through groove 22. The buckle 21 is engaged with the side wall of the comb tooth plate 4. The through groove 22 is provided on the side walls at both ends of the buckle 21. The bushing 23 is fixed to the inner side wall of the through groove 22 at one end of the buckle 21. An installation hole is provided on the side wall at the top of the buckle 21, and one end of the support frame 1 is connected to the side wall at the top of the buckle 21 through the installation hole. The bottom end of the through groove 22 is in an open state. The length of the buckle 21 is greater than the height of the comb tooth plate 4. The shape of the buckle 21 is "U"-shaped, and the distance between both ends of the buckle 21 is slightly smaller than the sum of the thickness of the comb tooth plate 4 and the thickness of the EPE 5.
[0022] It is convenient for the buckle 21 to be sleeved into the comb tooth plate 4 from the top through the opening of the "U"-shaped buckle 21, so that the buckle 21 clamps and positions the EPE 5 on the side wall of the comb tooth plate 4. At the same time, the buckle 21 is sleeved around the steel bar 32 through the through groove 22. By applying a downward pressure to the buckle 21, the buckle is driven to clamp the EPE 5 against the side wall of the steel bar 32.

[0024] It is convenient for the comb tooth plate 4 to pass through the steel bar 32 through the through groove 22 provided on its side wall, so that one end of the steel bar 32 can be outside the comb tooth plate 4, and thus a section of the steel bar 32 can be exposed outside the flange plate 31.
[0025] In the specific implementation process, as Figure 1 and Figure 2 shown, a through hole is provided on the side wall at the top of one end of the buckle 21. The other end of the support frame 1 is installed on the side wall at the top of the buckle 21 through the through hole, and the support frame 1 is supported between the comb tooth plate 4 and the template 6 through the buckle 21.
[0026] It is convenient for the support frame 1 to be supported on the side wall of the comb tooth plate 4 through the buckle 21, so as to limit the position of the comb tooth plate 4.
[0027] The working principle of the T-shaped beam flange plate EPE anti-leakage device provided by the present invention is as follows:
[0028] In use, first, erect the formwork 6 for casting the flange plate 31. Erect the steel bars 32 inside and on the surface of the formwork 6, position the steel bars 32, and then check the spacing between the designed steel bars 32 on the drawing according to the site conditions. Cut the EPE foam 5 so that the EPE foam 5 can be clamped on the side walls of the steel bars 32 through the cut gaps, with both ends of the steel bars 32 exposed. Enclose the peripheries of both ends of the steel bars 32. Then, place the comb-shaped plate 4 at the edge of the surface of the formwork 6. By adjusting its position, make the through slots 22 provided on the side wall of the comb-shaped plate 4 correspond to the positions of the steel bars 32. Then, pass the comb-shaped plate 4 through the steel bars 32 through the through slots 22 provided on the side wall, so that one end of the steel bars 32 is exposed outside the side wall of the comb-shaped plate 4, and its side wall abuts against the side wall of the previously clamped EPE foam 5, making the comb-shaped plate 4 the supporting surface of the EPE foam 5. Then, snap the buckle 21 downward from the front of the through slot 22 provided on the comb-shaped plate 4, so that the buckle 21 clamps the EPE foam 5 on the side wall of the comb-shaped plate 4, clamps and seals the cut opening of the EPE foam 5 supported by the steel bars 32, and makes the EPE foam 5 seal the gap between the comb-shaped plate 4 and the steel bars 32. This device has the advantages of being able to seal the gaps between the comb-shaped plates 4 and effectively reducing various quality problems caused by the loss of concrete slurry and aggregates during pouring.
[0029] Compared with the related technologies, the T-beam flange plate EPE foam anti-leakage device provided by the present utility model has the following beneficial effects:
[0030] The utility model provides an EPE anti-leakage slurry device for the flange plate of a T-shaped beam. Firstly, the EPE 5 can be cut according to the spacing of the steel bars 32 described in the design drawing and the length, width and spacing confirmed through on-site review. The cut EPE 5 is inserted into the interior of the steel bars 32 and placed on both sides respectively. The uneven EPE 5 is adjusted, and for the positions in conflict with the steel bars 32, corresponding notches are cut in the EPE 5 according to the situation, so that the EPE 5 can better fit the comb-shaped plate 4. Then, according to the position of the extended steel bars 32, the positioning structure 2 is clamped on the side wall of the comb-shaped plate 4, so that the EPE 5 is clamped on the side wall of the comb-shaped plate 4 through the positioning structure 2, and the notches cut in the EPE 5 are squeezed and fitted on the side wall of the steel bars 32 through the positioning structure 2, and at the same time, the notches on the side wall of the comb-shaped plate 4 are closed. The phenomenon of slurry leakage during the later concrete pouring is avoided, and then the pouring of the flange plate 31 is carried out; the formwork can be removed only after the concrete strength reaches the specified strength, and the remaining EPE 5 on the outside of the flange plate 31 must be cleaned up to ensure that there is no residue on the contact surface of the post-cast strip. This device has the advantages of being able to close the gaps between the comb-shaped plates 4 and effectively reducing various quality problems caused by the loss of concrete slurry and aggregates during pouring.
