Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a slurry-stopping sealing device for high pier steel formwork. Background Art
[0002] With the continuous development of my country's transportation infrastructure, the speed of road and bridge construction has accelerated. The application of high pier construction technology in highway bridge construction is becoming more and more extensive, and the application effect of this technology has an important impact on the overall construction level and the quality of highways. In the process of high pier body construction, due to the large height of the pier body and the large number of construction sections, climbing formwork, sliding formwork and flip formwork are usually used. During the structural construction stage, the formwork is attached to the already poured high pier body and rises layer by layer with the structural construction. Due to the gap between the formwork and the pier body, the concrete pouring process will affect the appearance quality of the poured pier body. Therefore, it is necessary to fit the formwork closely to the high pier body.
[0003] In the prior art, foam glue or double-sided tape is usually used at the bottom of the template to fit the template to the pier body. However, during the concrete pouring process, the concrete slurry flows down along the steel template, causing leakage and root rot at the joints, and the slurry contaminates the poured pier body. There is a problem of loose fit between the steel template and the pier body, and slurry flows during the concrete pouring process. Utility Model Content

[0006] The fixing device is provided with a plurality of hollow cavities side by side, and two adjacent hollow cavities are connected by an inflation hole; when the hollow cavities are filled with gas, the rubber strip expands outwards and fits tightly with the high pier.
[0007] In the embodiment of the present application, by inflating air into the inflation hole, the rubber strip is expanded outward and fits tightly with the high pier, thereby preventing slurry from flowing during concrete pouring, which would cause slurry leakage and root rot at the sections of the pier body, and the slurry from contaminating the poured pier body, affecting the appearance quality of the pier body and increasing the cost of subsequent processing.

[0014] In combination with the first aspect, in one embodiment, the groove includes a first groove located toward the high pier, and the first groove is close to the ground; when the hollow cavity is filled with gas, the rubber strip and the high pier fit tightly.
[0015] In the embodiment of the present application, when the air cavity is filled with gas, the rubber strip and the high pier fit tightly, so that the steel formwork and the high pier are blocked, preventing slurry from flowing during concrete pouring, resulting in slurry leakage and root rot at the sections of the high pier body, and slurry contaminating the poured pier body, affecting the appearance quality of the pier body and increasing the cost of subsequent processing.
[0016] In combination with the first aspect, in one embodiment, the groove further includes a second groove located on the bottom surface of the steel formwork, the second groove is adjacent to the side surface of the steel formwork, and when the hollow cavity is filled with gas, the rubber strip fits tightly against the ground.
[0017] In the embodiment of the present application, when the hollow cavity of the second groove is filled with gas, the rubber strip fits tightly against the ground, preventing part of the concrete slurry from sliding onto the ground and increasing the cost of subsequent processing.

[0023] In the embodiment of the present application, the fixing device can be tightly connected to the steel formwork by screws or bolts to prevent it from falling off during the long-term construction process, causing slurry to flow during concrete pouring, resulting in leakage and root rot at the sections of the high pier body, and slurry contamination of the poured pier body.

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0037] The embodiment of the present application provides a slurry-stopping sealing device for a high pier steel formwork, which can solve the problems in the prior art of loose fit between the steel formwork and the pier body and slurry flow during concrete pouring.
[0038] like Figure 1 , Figure 2 and Figure 3As shown, the present application provides an embodiment of a slurry-stop sealing device for high pier steel formwork, the sealing device 2 includes a fixing device 203 installed on the steel formwork 1, and also includes a plurality of rubber strips 201 installed on the fixing device 203, and both side edges of each rubber strip 201 are respectively connected to the fixing device 203, so that a hollow cavity 204 is formed between the inner wall of the rubber strip 201 and the fixing device 203, and an inflation hole 202 is provided at the connection between the rubber strip 201 and the fixing device 203 (only the position of the inflation hole is marked in the figure).
[0039] like Figure 3 As shown, the fixing device 203 is provided with a plurality of hollow cavities 204 in parallel, and two adjacent hollow cavities 204 are connected through the inflation hole 202, which can balance the air pressure on both sides and ensure the same expansion degree on both sides. When the air cavity 204 is filled with gas, the rubber strip 201 expands outwards and fits tightly with the pier body, preventing slurry from flowing during concrete pouring, causing slurry leakage and root rot at the sections of the pier body, and slurry contaminating the poured pier body, affecting the appearance quality of the pier body, and increasing the cost of later processing.
[0040] In this embodiment, the fixing device 203 is provided with two hollow cavities 204 side by side, and the two adjacent hollow cavities 204 are connected through the inflation hole 202. When the air cavity 204 is filled with gas, the two rubber strips 201 expand outwards to form an "M" shape, which fits tightly with the pier body, preventing slurry from flowing during concrete pouring, resulting in slurry leakage and root rot at the sections of the pier body, and slurry contaminating the poured pier body, affecting the appearance quality of the pier body, and increasing the cost of later processing.
[0041] In other embodiments, the fixing device 203 is provided with three hollow cavities 204 in parallel, and two adjacent hollow cavities 204 are connected through the inflation hole 202. When the air cavity 204 is filled with gas, the three rubber strips 201 expand outwards and fit tightly with the pier body, thereby preventing slurry from flowing during concrete pouring, causing slurry leakage and root rot at the sections of the pier body, and slurry contaminating the poured pier body, affecting the appearance quality of the pier body, and increasing the cost of later processing.
[0042] like Figure 2 and Figure 4 As shown, in some embodiments, the steel formwork 1 is provided with a groove, the fixing device 203 of the sealing device 2 is embedded in the groove, and the portion of the rubber strip 201 connected to the fixing device 203 is also located in the groove, a portion of the rubber strip 201 is located in the groove, and another portion of the rubber strip 201 is located outside the groove, thereby reducing the gap between the steel formwork 1 and the high pier body. When the rubber strip 201 expands outward, it fits tightly with the high pier body to prevent slurry from flowing during concrete pouring, resulting in slurry leakage and root rot at the sections of the high pier body, and slurry contamination of the poured pier body, affecting the appearance quality of the pier body and increasing the subsequent processing costs.
[0043] Furthermore, the width of the groove can at least meet the length of the concrete edge wrapping, which is the lap length of the concrete at the junction of adjacent templates. When pouring the pier body of the high pier, the length of the concrete edge wrapping shall not exceed 10 cm, otherwise it will affect the performance of the concrete and the structural performance of the pier body. In this embodiment, the width of the groove is 10 cm, so that the length of the concrete edge wrapping is controlled within 10 cm, which meets the performance of the concrete and ensures the structural safety of the pier body.
[0044] like Figure 3 As shown, further, a gap is provided between the above-mentioned groove and the adjacent rubber strip 201, which facilitates the installation and removal of the fixing device 203 on the one hand, and makes way for the rubber strip 201 to expand outward on the other hand. When the inflation hole 202 is inflated, the rubber strip 201 adjacent to the top groove can expand upward, and the rubber strip 201 adjacent to the bottom groove can expand downward, avoiding the formation of gaps and excessive extrusion between the grooves.
[0045] like Figure 4 As shown, in some embodiments, the groove includes a first groove 101 located toward the high pier, and the first groove 101 is close to the ground to facilitate the flow of concrete on the steel formwork 1 and facilitate the pouring of concrete; when the air cavity 204 is filled with gas, the rubber strip 201 and the high pier fit tightly, so that the steel formwork 1 and the high pier are blocked to prevent slurry from flowing during concrete pouring, resulting in leakage and root rot at the sections of the high pier body, and slurry contamination of the poured pier body, affecting the appearance quality of the pier body and increasing the cost of subsequent processing.
[0046] like Figure 4 As shown, in other embodiments, the groove includes not only the first groove 101, but also a second groove 102 located on the bottom surface of the steel template 1. The second groove 102 is adjacent to the side of the steel template 1. When the hollow cavity 204 of the second groove 102 is filled with gas, the rubber strip 201 fits tightly with the ground, preventing part of the concrete slurry from sliding onto the ground and increasing the cost of subsequent processing.
[0047] Preferably, the outer wall of the second groove 102 and the side of the steel template 1 are in the same plane. When the hollow cavity 204 is filled with gas, the rubber strip 201 expands outward, ensuring that a portion of the rubber strip 201 is in contact with the pier body, further reducing the gap between the template and the pier body.
[0048] In some embodiments, the length of the rubber strip 201 is: at least enough to surround a steel formwork 1 in the radial direction. In actual on-site construction, multiple steel formworks 1 are assembled to form a steel formwork assembly, and the length of the rubber strip 201 is at least enough to surround a steel formwork 1 in the radial direction. During installation, only the steel formworks 1 need to be assembled, and the rubber strip 201 can be closely fitted to the high pier to prevent slurry from flowing during concrete pouring, resulting in leakage and root rot at the sections of the high pier body, and slurry contamination of the poured pier body.
[0049] In some embodiments, the fixing device 203 is connected to the steel formwork 1 by screws or bolts. In this way, the fixing device 203 can be tightly connected to the steel formwork 1. Since the pier body is relatively long and the curing period of concrete is also long, in the actual on-site construction process, it is possible to avoid falling off during the long-term construction process, causing slurry flow during concrete pouring, resulting in leakage and root rot at the sections of the pier body, and slurry contamination of the poured pier body.
[0050] In some embodiments, the rubber strip 201 is fixed to the fixing device 203 by adhesive. Since the rubber strip is a flexible material, this connection method ensures the integrity of the rubber strip 201 and prevents gas from overflowing to the outside when the rubber strip 201 is inflated, thereby affecting the inflation effect of the rubber strip 201.
[0051] On the other hand, an embodiment of the use of a slurry-stopping sealing device for high pier steel formwork is provided, in which the rubber strip 201 is first fixed on the fixing device 203, and then the fixing device 203 is installed on the steel formwork 1, with the rubber strip 201 facing the outside, and air is inflated into the rubber strip 201 through the inflation holes 202 at the rubber strip 201 and the fixing device 203. At this time, the rubber strip 201 expands outward and fits tightly against the pier body.
[0052] In summary, the present application is achieved by installing a fixing device 203 on a steel formwork 1, and installing multiple rubber strips 201 on the fixing device 203, both sides of each rubber strip 201 are respectively connected to the fixing device 203 to form a hollow cavity 204, and an inflation hole 202 is provided at the connection between the rubber strip 201 and the fixing device 203. The fixing device 203 is provided with multiple hollow cavities 204 side by side, and two adjacent hollow cavities 204 are connected through the inflation hole 202. By inflating air into the inflation hole 202, the rubber strip 201 is expanded outward and fits tightly with the high pier, so as to prevent slurry from flowing during concrete pouring, which will cause slurry leakage and root rot at the sections of the high pier body, and the slurry contaminates the poured pier body, affecting the appearance quality of the pier body and increasing the subsequent processing costs.
