Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge construction, in particular to a template positioning tool for solving the problem of pier root rot. Background Art
[0002] Pier (column) root rot is a very common problem in bridge construction. Pier root rot is mainly manifested by irregular small pits on the concrete surface, large bubbles, excessive slurry leakage on both sides of the formwork, and concrete surface spots and uneven colors.
[0003] The main cause of pier root rot is the dense reinforcement in the pier, which restricts vibration and results in insufficient concrete vibration, incomplete air bubble expulsion, and some bubbles remaining between the concrete and the formwork. Furthermore, loose formwork joints, poor grouting at joints, or a loose connection between the bottom edge of the formwork and the edge of the abutment can also cause grout loss on the concrete surface during vibration, resulting in root rot.
[0004] The main reason why the formwork is not sealed is that it is difficult for the formwork itself to remain completely vertical during the pouring process. The initial verticality of the formwork, the deformation of the formwork when subjected to different heights and different squeezing forces of concrete, and the excessive correction of the verticality of the formwork by workers may all cause the formwork to tilt inward or outward to varying degrees, causing the cast pier body itself to have a certain degree of tilt. When a new round of pouring is carried out, the formwork needs to be repositioned. At this time, it is easy for the pier body and the formwork to not fit surface to surface, but line to surface, resulting in a loose fit. During the later pouring and vibration, concrete may leak out from the fit, thereby contaminating other parts of the pier body and causing the concrete surface to lose slurry, ultimately leading to root rot and other phenomena. Utility Model Content

[0007] Furthermore, the lower end surface of the baffle and the upper end surface of the pier body are in the same horizontal plane.
[0008] Furthermore, a side of the baffle away from the partition is provided with an upwardly curled edge.
[0009] Furthermore, the first driving device includes a first hydraulic cylinder that is arranged obliquely and connected to the side of the support plate away from the outer formwork; the telescopic rod of the first hydraulic cylinder passes through the support plate and is fixedly connected to the outer formwork; the axis of the first hydraulic cylinder passes through the axis of the pier body, and the height of one end of the cylinder body of the first hydraulic cylinder is higher than the height of the other end.

[0015] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects: the formwork positioning tooling of the present invention for solving the problem of pier body root rot, when in use, first uses the first driving device to pull the outer formwork away from the pier body and close to the support plate, then uses the second driving device to push the partition close to the upper end side wall of the pier body and stick it tightly, then uses the glue squeezing device to squeeze the glue into the gap between the partition and the pier body, after the glue solidifies, the partition is pulled apart, and then the first driving device is used to push the outer formwork to make it stick to the upper end outer wall of the pier body, and then the inner formwork is placed to start concrete pouring.

[0028] Example
[0029] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 5 As shown, the formwork positioning tooling for solving the root rot of the pier body in this embodiment includes a pier body 11, a base plate 12 horizontally arranged around the outer wall of the pier body 11, and a plurality of formwork assemblies arranged around the outer wall of the pier body 11; the formwork assembly includes a support plate 21 connected to the base plate 12 and vertically arranged, an outer formwork 22 arranged between the support plate 21 and the pier body 11, a first driving device for driving the outer formwork 22 to move, a partition 23 vertically attached to the base plate 12, a baffle 24 horizontally arranged on the partition 23, and a second driving device for driving the partition 23 to approach / move away from the pier body 11, and a glue squeezing device connected to the partition 23; a gap is provided between the support plate 21 and the base plate 12 for the partition 23 to pass through. Specifically, when in use, the first driving device is used to pull the outer formwork 22 away from the pier body 11 and close to the support plate 21, and then the second driving device is used to push the partition 23 close to the upper side wall of the pier body 11 and close to it, and then the glue squeezing device is used to squeeze the glue into the gap between the partition 23 and the pier body 11 (as shown in the attached figure). Figure 5As shown, for ease of understanding, a relatively exaggerated gap is shown in the attached figure, and the actual inclination angle of the pier body 11 is much lower than this). After the glue solidifies, the partition 23 is pulled open, and then the first driving device is used to push the outer formwork 22 to make it stick to the outer wall of the upper end of the pier body 11, and then the inner formwork is placed to start concrete pouring. In this way, by first curing a layer of sealant on the outer wall of the upper end of the pier body 11 and then installing the outer formwork 22, the fit between the outer formwork 22 and the pier body 11 can be made tighter, and it is less likely to leak during pouring and vibration, and it is not easy to contaminate the already poured pier body 11, which can solve the problem of rotten roots of the pier body 11 to a certain extent.
[0030] The lower end surface of the baffle 24 in this embodiment is in the same horizontal plane as the upper end surface of the pier body 11. Specifically, the sealant can be well sealed by the baffle 24 to prevent the sealant from remaining on the upper end wall of the pier body 11.
[0031] In this embodiment, the baffle 24 is provided with an upwardly curled edge on a side away from the partition 23. Specifically, the baffle 24 can be attached to the upper side wall of the pier body 11 more easily in this way.
[0032] The first driving device in this embodiment includes a first hydraulic cylinder 25 that is tilted and connected to the side of the support plate 21 away from the outer formwork 22; the telescopic rod of the first hydraulic cylinder 25 passes through the support plate 21 and is fixedly connected to the outer formwork 22; the axis of the first hydraulic cylinder 25 passes through the axis of the pier body 11, and the height of one end of the cylinder body of the first hydraulic cylinder 25 is higher than the height of the other end. Specifically, this can cause the outer formwork 22 to move in an oblique direction (as shown in the attached figure). Figure 2 -Attached Figure 3 As shown), space can be left for the partition plate 23 to pass through. And the partition plate 23 and the outer template 22 will not block each other.
[0033] In this embodiment, a slide tube 27 is provided on one side of the support plate 21 where the first hydraulic cylinder 25 is located. A slide rod 26 is provided on the side of the outer formwork 22 closest to the support plate 21. The slide rod 26 passes through the support plate 21 and slides within the slide rod 26. The axis of the slide rod 26 is parallel to the axis of the first hydraulic cylinder 25. Multiple slide tubes 27 and multiple slide rods 26 are provided, with each corresponding to the other. Specifically, the coordination of the slide tubes 27 and slide rods 26 ensures more stable movement and fixation of the outer formwork 22, preventing any shaking.
[0034] The second driving device in this embodiment includes a second hydraulic cylinder 28 horizontally arranged on the bottom plate 12 , and a telescopic rod of the second hydraulic cylinder 28 is fixedly connected to the partition plate 23 .
[0035] The glue extrusion device in this embodiment includes a glue pump 29 and a liquid guide tube 210 disposed at the outlet of the glue pump 29. The liquid guide tube 210 passes through the partition 23 and is disposed between the partition 23 and the pier body 11. Specifically, the liquid guide tube 210 is a flexible tube, and a mold release agent is pre-sprayed on the partition 23 and the baffle 24 to prevent the sealant from adhering to the partition 23.
[0036] In this embodiment, the support plate 21 and the bottom plate 12 are connected via a plurality of support rods 211 .
[0037] In summary, the formwork positioning tooling for solving the problem of pier body root rot in this embodiment, when in use, first uses the first driving device to pull the outer formwork 22 away from the pier body 11 and close to the support plate 21, and then uses the second driving device to push the partition 23 close to the upper side wall of the pier body 11 and stick it tightly, and then uses the glue squeezing device to squeeze the glue into the gap between the partition 23 and the pier body 11, after the glue solidifies, pull the partition 23 apart, and then use the first driving device to push the outer formwork 22 to stick to the outer wall of the upper end of the pier body 11, and then put in the inner formwork to start concrete pouring. In this way, by first curing a layer of sealant on the outer wall of the upper end of the pier body 11 and then installing the outer formwork 22, the fit between the outer formwork 22 and the pier body 11 can be made tighter, and it is less likely to leak during pouring and vibration, and it is not easy to contaminate the already poured pier body 11, which can solve the problem of pier body 11 root rot to a certain extent.
