Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an auxiliary device for preventing wall pollution by slipforming. Background Technology

[0002] Slipform construction is a highly efficient continuous concrete forming process. During concrete pouring, a hydraulic lifting system moves a slipform continuously upwards along the surface of the poured concrete, allowing the concrete to gradually form within a dynamic formwork, completing the pouring of beams and columns in one operation. However, during the slipform's movement, cement slurry generated during concrete pouring flows downwards along the gaps between the slipform and the sides of the beams and columns, causing surface contamination and affecting the appearance and quality of the finished concrete beams and columns. Summary of the Invention

[0003] To address the problem of cement slurry flowing downwards along the gap between the slipform and the beam / column surface during the current slipforming process, causing wall contamination, this invention proposes an auxiliary device for slipforms to prevent wall contamination. This device consists of multiple units, evenly distributed on the outer side of the slipform. The rubber pads at the ends of the receiving plates can catch the downward-flowing cement slurry, improving the forming quality of concrete beams and columns.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A sliding formwork auxiliary device for preventing wall contamination, with an adjustable vertical position on the sliding formwork, includes a mounting base. A receiving plate is hinged to the side of the mounting base away from the sliding formwork. The receiving plate has an "L"-shaped longitudinal section. A support plate is fixed to the side of the receiving plate near the sliding formwork, and the support plate contacts the side of the sliding formwork. A rubber pad is fixed to the lower end of the receiving plate, and the end of the rubber pad contacts the side of the wall. The end of the rubber pad near the wall is higher than the end away from the wall. Multiple sliding formwork auxiliary devices are evenly distributed on the outer surface of the sliding formwork, with the sides of the receiving plates in adjacent devices contacting each other. The adjustable vertical position of the sliding formwork auxiliary device allows it to catch as much cement slurry flowing downwards from the wall surface as possible, as needed.

[0005] Preferably, the outer side of the sliding mold is provided with a sliding groove, and a slider is slidably disposed in the sliding groove. One end of the slider extends out of the sliding groove and is fixedly connected to the mounting base. A screw is screwed onto the mounting base, and the end of the screw passes through the mounting base and contacts the sliding mold.

[0006] Preferably, the cross-section of the groove is convex.

[0007] Preferably, a hinge seat is fixed to the side of the mounting base away from the sliding mold, and the upper end of the receiving plate is hinged to the hinge seat via a hinge shaft. Two hinge seats are provided, arranged opposite each other, to increase the stability of the receiving plate on the mounting base.

[0008] Preferably, both the hinge seat and the receiving plate have insertion holes at their ends, into which pins are inserted. When the receiving plate falls under gravity, this prevents the receiving plate from rotating again and allows the received cement slurry to fall back onto the side of the wall.

[0009] Preferably, the slipform has a circular cross-section, and the receiving plate has an arc-shaped cross-section, the center of which coincides with the center of the circular cross-section of the slipform. When the cast beam or column is cylindrical, the slipform has a circular cross-section.

[0010] Preferably, the slipform has a rectangular cross-section. When the cast beam or column is a quadrangular prism, the slipform has a rectangular cross-section.

[0011] Preferably, the rubber pad and the receiving plate are fixedly connected by bolts.

[0012] Through the above technical solution, the beneficial effects of this utility model are as follows: In this utility model, the end of the rubber pad at the end of the receiving plate contacts the side of the wall. During the continuous upward movement of the slipform, it can receive the downward flowing cement slurry. Multiple slipform auxiliary devices are simultaneously set and evenly distributed on the outer side of the slipform. At the same time, their vertical position on the slipform is adjustable, which can receive as much cement slurry flowing downward from the wall surface as needed, thereby improving the quality of the concrete beams and columns after molding. Meanwhile, the receiving plate is hinged to the mounting base, which avoids interference between the entire slipform auxiliary device and the ground position when the slipform contacts the ground where the beams and columns are supported, thus reducing the difficulty of slipform support.

Figure 1 Enlarged view of the structure at point A in the middle; Figure 3 This is a side view of the anti-pollution sliding mold auxiliary device and the sliding mold set on the side of the wall according to the present invention.

[0014] In the attached diagram, the following numbers are used: 1 is the mounting base, 2 is the receiving plate, 3 is the support plate, 4 is the rubber pad, 5 is the hinge seat, 6 is the hinge shaft, 7 is the pin, 100 is the sliding mold, 101 is the sliding groove, and 200 is the wall. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-3 As shown, this embodiment provides an auxiliary device for preventing wall contamination during slipforming, including a mounting base 1. A receiving plate 2 is hinged to the side of the mounting base 1 away from the slipforming 100. (Refer to...) Figure 2Two opposing hinge seats 5 are welded and fixed on the side of the mounting base 1 away from the sliding mold 100, and the upper end of the receiving plate 2 is hinged to the two hinge seats 5 through the hinge shaft 6. The longitudinal section of the receiving plate 2 is "L" shaped. A support plate 3 is fixed on the side of the receiving plate 2 near the slipform 100. The support plate 3 contacts the side of the slipform 100, leaving a certain storage space for the cement slurry. A rubber pad 4 is fixed at the lower end of the receiving plate 2. The rubber pad 4 is fixed to the receiving plate 2 by bolts. The end of the rubber pad 4 contacts the side of the wall 200. The end of the rubber pad 4 near the wall 200 is higher than the end away from the wall 200 to prevent the cement slurry from flowing back to the wall 200. The cement slurry can fall from both sides of the receiving plate 2 onto the pouring ground.

[0016] Furthermore, multiple slipform auxiliary devices are evenly distributed on the outer surface of the slipform 100, with the sides of the receiving plates 2 in adjacent slipform auxiliary devices contacting each other. In this embodiment, the cast beam / column is cylindrical, therefore the cross-section of the slipform 100 is circular, and the cross-section of the receiving plate 2 is arc-shaped, with its center coinciding with the center of the circular cross-section of the slipform 100. Multiple slipform auxiliary devices work together to receive the cement grout on the outer surface of the entire cylindrical beam / column, and the cement grout can flow out through the gap between adjacent receiving plates 2.

[0017] In other embodiments, the cross-section of the slipform 100 is rectangular, the cast beams and columns are quadrangular prisms, there are 4 slipform auxiliary devices, and the side of the receiving plate 2 can be flush with the two end faces of the slipform 100.

[0018] Furthermore, the vertical position of the sliding mold auxiliary device on the sliding mold 100 is adjustable, for reference... Figure 1 and Figure 2 The outer side of the sliding mold 100 is provided with a sliding groove 101. In this embodiment, the cross-section of the sliding groove 101 is a horizontally convex "U" shape. A slider matching the shape of the sliding groove 101 is slidably arranged in the sliding groove 101. One end of the slider extends out of the sliding groove 101 and is welded and fixed to the mounting base 1. A screw (not shown in the figure) is screwed onto the mounting base 1. The end of the screw passes through the mounting base 1 and contacts the sliding mold 100. Loosening the screw allows the slider to slide freely in the sliding groove 101. Tightening the screw causes the screw to abut against the side of the sliding mold 100, and the slider's position in the sliding groove 101 is fixed.

[0019] When the lower end of the sliding formwork 100 contacts the ground supporting the beam and column, the support plate 2, which is hinged to the mounting base 1, can be lifted directly to avoid positional interference between the sliding formwork 100 and the ground supporting the beam and column. When the sliding formwork 100 rises to a suitable distance, the support plate 2 falls under the action of gravity, and the rubber pad 4 at its lower end contacts the wall surface 200. To prevent the support plate 2 from shaking, insertion holes are provided at the ends of both the hinge base 5 and the support plate 2, and pins 7 are inserted into the insertion holes.

[0020] When using this device, at the initial formwork erection, first pull out the pin 7 in the socket to avoid positional interference with the beam and column support ground. When the sliding form 100 rises to a suitable distance and the support plate 2 falls under gravity, and the rubber pad 4 at its lower end contacts the wall 200, then insert the pin 7 into the socket to prevent the support plate 2 from shaking. At this time, loosen the screw and manually adjust the position of multiple sliders in the slide groove 101. After the height of multiple sliders is kept consistent, tighten the screw. This allows the rubber pad to adapt to different grout flow states during concrete pouring at different heights, reducing the probability of cement grout remaining on the side of the beam, column, and wall 200.

[0021] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
