Description

Technical Field

[0001] The invention belongs to the technical field of grouting auxiliary tools for assembled buildings, and in particular relates to a grouting plugging device component for prefabricated columns of prefabricated assembled buildings. Background Art

[0002] Prefabricated buildings are buildings that are produced in factories and then transported to the site for assembly. This can greatly shorten the construction period. my country is currently vigorously promoting prefabricated buildings. Prefabricated buildings are buildings that are built, used and managed using standardized design, factory production, industrialized construction and information management. They are an effective way to promote the transformation of traditional construction methods to modern methods such as intensive, economical, environmentally friendly, green and technological. At present, in the construction of prefabricated frame structure buildings, the nodes of prefabricated columns, prefabricated composite beams and prefabricated composite slabs are cast-in-place connections. There is generally a 20mm grouting channel between the upper and lower prefabricated columns. High-strength grouting materials above C80 are required for pressure grouting and plugging. Usually, prefabricated columns connected by semi-grouting sleeves and full-grouting sleeves are pressure grouting through the lower grouting port. The upper row of grouting ports flow out slurry in turn, which determines that the grouting is dense. After the slurry flows out of the lower grouting port and the upper row of grouting ports, plastic plugs are used to plug them. The grouting holes are not effectively blocked, resulting in leakage. The grouting holes can only be blocked by observation after grouting, resulting in leakage. It is troublesome to block the grouting holes. When using wooden plugs to block, you need to keep an eye on the grouting holes to prevent missing the opportunity to block, but this is too troublesome. In addition, there is no limit fixing mechanism after the wooden plug blocks the grouting holes. If the wooden plug falls off, the grouting holes will leak slurry quickly, resulting in grouting failure.

[0003] A grouting and plugging device for prefabricated columns of assembled buildings with announcement number CN213234302U comprises a grouting mold body, wherein the right side of the grouting mold is equipped with a grouting pipe head, a sleeve is sleeved on the outer side of the right end of the grouting pipe head, a conical sleeve is fixedly connected to the inner side of the right end of the sleeve, a grouting nozzle is inserted into the inner side of the conical sleeve, and a connecting block is fixedly connected to the upper and lower sides of the right end of the sleeve, and a fixed top bolt is vertically connected to the connecting block. The design method of plugging with a plastic plug cannot meet the plugging conditions well, and the part of the plastic plug inserted into the prefabricated column can only be plugged with mortar in the later stage, so the effective cross-section of the node of the prefabricated column is greatly reduced, which is contrary to the principle of "strong node, weak component" of the assembled structure; at the same time, in the process of plugging the grouting hole, the high-strength grouting material also overflows the grouting hole, and the plugging cannot ensure the good plugging of the grouting material. In addition, when grouting the prefabricated column, the nozzle of the grouting device is docked at the feed port of the mold device. After the grouting is completed, the nozzle is pulled out and then the sealing device is installed at the feed port. The operation is cumbersome and not convenient enough.

[0004] Therefore, it is urgent to find a reasonable plugging device and a plugging solution to solve the leakage problem, as well as to solve the problem of the existing wooden plugs or plastic plugs occupying the effective cross-section of the prefabricated columns. Summary of the invention

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Embodiment 1: a kind of Figure 1 The grouting plugging assembly of the prefabricated building prefabricated column shown is mainly used for plugging the grouting holes and drainage holes of the template during the grouting construction process of the prefabricated building bottom. The plugging assembly is improved to address the problem that the existing plugging construction process lacks an effective plugging device, and the existing plugging devices generally stop the operation after observing the drainage hole for slurry leakage, and then stop the operation gradually and plug the leakage. The plugging assembly mainly includes an overflow plugging assembly 2 and a grouting plugging assembly 11, as well as clamps and the like respectively provided to each other.

[0028] This embodiment adopts Figure 1-Figure 3 The structural form, from Figure 1 It can be seen that the overflow plugging component 2 located at the upper part mainly plugs the grouting hole, and the grouting plugging component 11 located at the lower part mainly plugs the grouting hole. Since the concrete needs time to solidify after the grouting is completed, the above two plugging components can maintain the plugging until the formwork is removed. It has the advantages of simple operation and good plugging effect, and the plugging process effectively reduces slurry leakage, especially the plugging of the slurry discharge hole. The overflow plugging component 2 can ensure that a warning signal is issued without slurry discharge.

[0029] Specifically, the overflow blocking assembly 2 includes a clamp and an upper blocking mechanism, wherein the upper blocking mechanism includes a rectangular frame body, the rectangular frame body includes a bottom plate, two side panels, and a top plate, wherein a gap is left in the middle of the bottom plate. Figure 1 and Figure 2It can be seen that two slide bars 4 are vertically fixed on the inner side of the two side panels, and the top and bottom of the two slide bars are fixedly connected to the top plate and the bottom plate respectively. Slide blocks 6 are mounted on the two side slide bars 4, and the height of the slide blocks 6 is less than the height difference between the top plate and the bottom plate, so that the slide blocks 6 have the freedom to slide up and down along the slide bars 4.

[0030] like Figure 4 As shown, a strip groove 18 is provided in the center of the bottom plate. A conical hole 7 is provided in the center of the slider 6, and the inner end diameter of the conical hole 7 is larger than the outer end diameter. A rubber or wooden cone 8 is matched and set in the conical hole 7, and a through hole is provided in the center of the conical body 8 and a wooden stick 9 is set. The wooden stick 9 can freely adjust the extension amount in the central through hole of the conical body 8. The wooden stick 9 is based on passing through the slurry discharge hole of the template 1 and contacting the assembly column 34. The end of the wooden stick 9 is exposed to facilitate visual inspection of its moving state.

[0031] A buzzer 10 is fixed in the middle of the top panel, and the touch switch 23 of the buzzer 10 is located below the top panel. When the grout moves upward in the template, it drives the wooden stick upward, and then drives the slider upward. When the slider moves upward to the top and triggers the touch switch, the buzzer alarm is triggered. The buzzer is a small generating component purchased through purchase, and the bottom of the buzzer has a touch switch. During assembly, a hole can be opened in the top panel to introduce the buzzer or only the touch switch of the buzzer into the inside, and it is triggered after the slider moves upward. Figure 2 It can be seen that the slider 6 is initially located at the bottom of the frame, and is located at the top of the frame when the alarm is sounded. Figure 4 It can be seen that the initial positions of the cone 8 and the wooden stick 9 are located at the bottom of the strip groove 18, and they are located at the top of the strip groove 18 when the alarm is sounded.

[0032] like Figure 1 and Figure 3 The clamping member includes two L-shaped clamps 20 and four transverse connecting rods 3. Each L-shaped clamp 20 includes a pulling plate and a hanging plate. Two guide tubes 15 are fixed transversely on the outer surface of the pulling plate of each L-shaped clamp 20. A connecting rod 3 is respectively installed in each guide tube 15. The inner ends of each connecting rod 3 are respectively fixed on both sides of the rectangular frame body. Figure 3 In the embodiment, a stopper 16 is provided on each connecting rod 3, and a spring seat is provided at the inner end of the guide tube 15, and a spring 17 is sleeved between the spring seat and the stopper 16, so that in a natural state, the springs on both sides drive the L-shaped clamps 20 on both sides to retract inward. Figure 4 It can also be seen that the inner wall of the hook plate of the L-shaped card 20 is respectively provided with anti-skid teeth 21 or gaskets for pressing together with the template surface. In addition, a handle 22 is fixed to the outer wall of the hook plate of the L-shaped card 20.

[0033] When the overflow plugging assembly 2 is in use, the handles 22 on both sides are pulled outward to expand the L-shaped clips 20 on both sides outward, and then the handles are released at the position of the template slurry discharge hole, and the overflow plugging assembly 2 is assembled at the position of the slurry discharge hole. In the natural state, the slider 6, the cone 8 and the wooden stick 9 are located at the lower side. During assembly, it is necessary to ensure that the wooden stick is inserted into the template slurry discharge hole. After assembly, push the wooden stick 9 inward until it cannot be pushed anymore, and avoid contact between the wooden stick and the built-in steel bars.

[0034] like Figure 1 As shown, the grouting plugging assembly 11 includes a clamp and a lower plugging mechanism, and its clamp is the same as the clamp of the overflow plugging assembly 2, and will not be repeated. The lower plugging mechanism includes a bottom plate and two side panels, and a grouting hole 12 is set at the bottom of the bottom plate. Usually, the aperture of the grouting hole 12 is larger than the aperture of the template grouting hole. A guide groove 13 is set on the inner side of the two side panels, and a slide plate 14 is matched in the guide groove 13 on both sides. When in use, the slide plate 14 is slid upward, and the grouting pipe is inserted into the grouting hole 12. When the buzzer alarms, while the grouting pipe is pulled out, the slide plate 14 actively or driven to move downward to plug the grouting hole 12. When assembling the grouting plugging assembly 11, the handles 22 of the L-shaped clamps 20 on both sides are pulled outward, so that the L-shaped clamps 20 on both sides are unfolded outward, and then the hands are released at the position of the template grouting hole, and the grouting hole 12 corresponds to the position of the template grouting hole, which is simple and convenient to operate. The grouting hole 12 of the grouting plugging assembly 11 is consistent with the model of the grouting pipe and can be matched and assembled, and can support the grouting pipe.

[0035] Example 2: Based on Example 1, Figure 5 and Figure 6 Another prefabricated and assembled building prefabricated column grouting plug assembly is shown. The similarities between this plug assembly and Example 1 are not repeated, except that: this plug assembly is additionally provided with a locking component. When Example 1 realizes the clamping process by compressing two L-shaped clamps with four springs on both sides, this embodiment can also be used to achieve absolute fixation with a locking component.

[0036] Figure 5 It can be seen that a locking component includes a main swing rod 25, an auxiliary swing rod 26 and a pull rope 31. An axle seat 24 is set at the outer end of the pulling plate of the L-shaped clamp on both sides, and a first axis 27 is hinged in one side axle seat, and a second axis 28 is hinged in the other side axle seat. One end of the main swing rod 25 is hinged to the axle seat on one side through the first axis 27, one end of the auxiliary swing rod 26 is hinged to the axle seat on the other side through the second axis 28, and the middle part of the auxiliary swing rod 26 is hinged to the middle part of the main swing rod 25 through the third axis 29. A handle 30 is installed at the end of the main swing rod. When the handle is pressed to one side, as shown in FIG. Figure 6As shown, the L-shaped clips on both sides can be compressed and retracted inward to the limit position at the same time. A hook 32 is provided at one end of the pull rope 31, and a buckle 33 (belt buckle or 8-shaped buckle) is provided at the other end. The hook is connected to the handle. After the pull rope is wrapped around the template, the buckle 33 at one end is fixed (or tied) to the handle 22 of the L-shaped clip on the other side.

[0037] Embodiment 3: Based on the above embodiments, a swinging pressure plate can be provided for the grouting plugging assembly 11 to replace the sliding plate. For example, the plugging mechanism includes a bottom plate and two side panels, a grouting hole is provided through the lower part of the bottom plate, two side panels are respectively hinged to two swing rods, the ends of the four swing rods on both sides are hinged to the four top corners of a pressure plate, and a magnet is fixed on the inner side of the pressure plate, or a tension spring is connected between the pressure plate and the two side panels, so that the pressure plate is always attached to the bottom plate. A convex column is provided on the inner side wall of the pressure plate, and the diameter of the convex column matches the diameter of the grouting hole. After the pressure plate is swung upward, the pressure plate is pressed against the upper part of the bottom plate under the action of the magnet or the tension springs on both sides, which is equivalent to the sliding plate in Embodiment 1 sliding upward and being located in the upper side position; after the pressure plate is swung downward, the pressure plate is pressed against the lower part of the bottom plate under the action of the magnet or the tension springs on both sides, which is equivalent to the sliding plate in Embodiment 1 moving downward and being located in the lower side position. When the pressing plate is located at the lower side, the convex column located at the rear side of the pressing plate is matched and sleeved into the grouting hole to ensure that the surface of the precast column is flat after pouring.

[0038] Example 4: Based on Example 1 and the above examples, a solenoid valve is installed on the grouting pipe, and the buzzer lead signal line is connected to the signal input terminal of the controller. The controller controls the solenoid valve to close according to the buzzer trigger signal, and stops the grouting directly or with a delay to avoid overflow from the top due to untimely closing.

[0039] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modification, equivalent substitution, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
