Detailed Embodiment

[0023] The present invention will be further described in detail below with reference to the drawings and embodiments, so as to make the purpose, technical solution and advantages of the present invention clearer. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] Refer to Figure 1 , only a partial structure of the formwork is shown in the figure. The formwork grout stopping device of an exemplary embodiment of the present invention includes a formwork 1, a support member 4 is provided at the bottom of the formwork 1, a clamping member 2 is movably provided in the support member 4, and a sealing strip 3 for grout stopping is provided in the clamping member 2.

[0025] After the formwork 1 is installed on the surface of the concrete structure, with the mutual cooperation of the support member 4, the clamping member 2 and the sealing strip 3, the clamping member 2 can drive the sealing strip 3 to closely adhere to the surface of the concrete structure. When pouring concrete subsequently, it can effectively prevent the concrete slurry from leaking out from the bottom opening of the formwork 1, thereby improving the surface appearance quality of the concrete structure.

[0026] The support member 4 is arranged on the transverse rib 14 at the bottom of the formwork 1. The support member 4 is of an L-shaped structure. The vertical side of the support member 4 is perpendicular to the transverse rib 14, and the horizontal side of the support member 4 is parallel to the transverse rib 14. The vertical side of the support member 4 is welded to the transverse rib 14. The length of the horizontal side of the support member 4 is not greater than the distance between the panel of the formwork 1 and the vertical side of the support member 4 to prevent the horizontal side of the support member 4 from interfering with the installation of the formwork 1.

[0027] The clamping member 2 is arranged between the horizontal side of the support member 4 and the transverse rib 14. Both the horizontal side and the vertical side of the support member 4 are rectangular plates. One or more connection holes penetrating the vertical side are arranged on the vertical side of the support member 4. A connecting rod 5 is arranged on the surface of the clamping member 2 close to the vertical side. The position of the connecting rod 5 corresponds to the position of the connection hole. The connecting rod 5 is a screw rod. After the connecting rod 5 passes through the connection hole, it is connected to the vertical side through a nut 9. The connecting rod 5 enables the clamping member 2 to move between the horizontal side of the support member 4 and the transverse rib 14.

[0028] Reference Figure 2 , Figure 2 Only a partial structure at the bottom of the formwork is shown. One or more adjustment holes penetrating the vertical side are also arranged on the vertical side of the support member 4. The adjustment holes are preferably on the same straight line as the connection holes. The adjustment holes are threaded holes. An adjustment member 6 is arranged in the adjustment holes. The adjustment member 6 is a screw rod. The adjustment member 6 is used to move the clamping member 2. After the clamping member 2 moves until the sealing strip contacts the surface of the concrete structure, the adjustment member 6 abuts against the clamping member 2.

[0029] The adjustment member 6 is threadedly connected to the vertical side of the support member 4. One end of the adjustment member 6 abuts against the clamping member 2, and the other end of the adjustment member 6 is an operating end. When the formwork 1 has an installation error due to improper trimming, loose connection of fasteners, or deformation after multiple uses of the formwork, and a gap is generated between the bottom opening of the formwork 1 and the concrete structure, the nut 9 can be loosened, and the operating end of the adjustment member 6 can be rotated to drive the clamping member 2 to move by the adjustment member 6, so that the clamping member 2 and the sealing strip 3 fill the gap between the formwork 1 and the concrete structure, and the sealing strip 3 is closely attached to the concrete structure, effectively preventing the leakage of slurry from the bottom opening of the formwork 1 and improving the surface appearance quality of the concrete structure.

[0030] The cross-sectional shape of the clamping member 2 is a U-shaped structure, including two parallel side plates 21. The two side plates 21 are integrally connected by a bottom plate 22. The bottom plate 22 is connected to the ends of the side plates 21. The sealing strip 3 is connected to the clamping member 2 in an insertion manner. The sealing strip 3 can also be connected to the clamping member 2 by glue or screws to prevent the sealing strip 3 from falling off the clamping member 2. The connecting rod 5 is arranged on the surface of the bottom plate 22 close to the vertical side of the support member 4. The connecting rod 5 is perpendicular to the bottom plate 22. The connecting rod 5 is welded or detachably connected to the bottom plate 22. The cross-sectional length of the side plate 21 is not greater than the cross-sectional length of the horizontal side of the support member 4. The cross-sectional height of the bottom plate 22 is adapted to the cross-sectional height of the support member 4 (referenceFigure 1 , Figure 2 ), to avoid the generation of gaps between the clamping member 2 and the support member 4, which may affect the slurry stopping effect.

[0031] In the middle of each side plate 21, a fixing boss 23 is integrally provided. The fixing boss 23 is vertically arranged on the mutually approaching surfaces of the two side plates 21. Correspondingly, the cross-sectional shape of the sealing strip 3 is rectangular. Clamping grooves are respectively arranged on two opposite side surfaces of the sealing strip 3. The shape of the clamping groove is adapted to the shape of the fixing boss 23. The cross-sectional width of the sealing strip 3 is slightly larger than the length between the two side plates 21. The sealing strip 3 is snapped into the clamping member 2. With the mutual cooperation of the clamping groove and the fixing boss 23, the stability of the sealing strip 3 in the clamping member 2 can be further improved, and the sealing strip 3 can be prevented from being damaged during the fixing process of the sealing strip 3, avoiding affecting the slurry stopping effect of the sealing strip 3.

[0032] The sealing strip 3 adopts an ethylene propylene diene monomer (EPDM) sealing strip. The EPDM sealing strip has good chemical stability, high temperature resistance and aging resistance. After contacting with the concrete, the EPDM sealing strip can resist the erosion of chemical substances in the concrete, and can also avoid the influence of the heat released by the hydration of the concrete on its working reliability. During the process of the turnover use of the formwork, the service life of the sealing strip can be improved.

[0033] The cross-sectional length of the sealing strip 3 is slightly larger than the cross-sectional length of the side plate 21. For example, the cross-sectional length of the sealing strip 3 is 5 - 8 mm larger than the cross-sectional length of the side plate 21. The sealing strip 3 has elasticity. After the formwork 1 is installed, the sealing strip 3 can closely adhere to the surface of the concrete structure body to prevent slurry leakage at the bottom opening of the formwork 1.

[0034] Reference Figure 3 , during the installation process of the formwork 1, one row or multiple rows of embedded tie rods 8 are also arranged at the position close to the top of the concrete structure body 7. After the formwork 1 is installed in place, the embedded tie rods 8 are connected to the vertical back ribs 12 of the formwork 1. Through the embedded tie rods 8, the stability of the connection at the bottom opening of the formwork 1 can be further enhanced, and the generation of gaps between the bottom opening of the formwork 1 and the concrete structure body 7 can be avoided.

[0035] The panel 11 of the formwork 1 is adhesively arranged on the side surface of the constructed concrete structure body 7. The clamping member 2 is located below the top surface of the concrete structure body 7 and above the embedded tie rods 8, so that the sealing strip 3 can be in full contact with the side surface of the concrete structure body 7, improving the slurry stopping effect at the bottom opening of the formwork 1.

[0036] The above is only a detailed description of the specific implementation manner of the present invention, rather than a limitation to the present invention. Those skilled in the relevant technical fields should include various substitutions, modifications and improvements made without departing from the principles and scopes of the present invention within the protection scope of the present invention.
