Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an umbrella-shaped, frameless auxiliary construction opening sealing device and its construction method. Background Technology

[0002] As building heights continue to increase, the sealing of bolt holes is frequently encountered in civil engineering and construction, especially during exterior wall construction. These bolt holes are typically created for installing various equipment or performing other construction operations, but they need to be sealed after construction to ensure the building's appearance and functionality. Traditional sealing methods usually require the use of external scaffolding to allow construction workers to operate at heights.

[0003] Traditional sealing methods primarily involve using external scaffolding, such as traditional scaffolding, to assist construction workers in sealing bolt holes. While this method can effectively complete the sealing work, it requires a significant investment of manpower and resources, has a long construction period, and is inefficient. The existing technology in this field has the following main problems: First, using external scaffolding requires a large investment of manpower and resources, increasing construction costs. Second, because it involves working at heights, the construction risks are high, and safety accidents are prone to occur. Third, using external scaffolding results in a long construction period, low efficiency, and impacts the construction schedule. Finally, the need for external scaffolding may have a certain impact on the appearance of the building. Summary of the Invention

[0038] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0039] Reference Figures 1 to 5 As shown in the drawings, the present application provides a hole sealing device of an umbrella-shaped frameless body auxiliary construction, comprising: a containing sleeve 1, a grouting pipe 2, a sealing assembly 3, and a driving assembly 4.

[0040] The containing sleeve 1 is arranged in the hole of the outer wall 5.

[0041] In the present embodiment, the length of the containing sleeve is slightly longer than the length of the hole of the outer wall. The containing sleeve is arranged obliquely in the hole. Specifically, the upper end of the containing sleeve 1 is arranged towards the inner side of the outer wall 5. The lower end of the containing sleeve 1 is arranged away from the inner side of the outer wall 5.

[0042] The grouting pipe 2 has an input end and an output end. The output end of the grouting pipe 2 is detachably mounted to the inner end of the containing sleeve 1. The end face of the output end of the grouting pipe 2 is pressed against the inner side of the outer wall 5 to close the inner port of the hole.

[0043] In the present embodiment, the upper end of the containing sleeve is detachably hinged to the output end of the grouting pipe through a hinge shaft. When the hinge shaft is removed, the containing sleeve is separated from the grouting pipe.

[0044] As a preferred embodiment, in combination with Figure 2 and Figure 4As shown, a piston plate 21 is slidably arranged in the grouting pipe 2. The piston plate 21 is connected with a handle 22. The handle 22 extends to the outside of the input end of the grouting pipe 2.

[0045] A spring is arranged in the output end of the grouting pipe. The piston plate is supported by the spring.

[0046] In the embodiment, the outer side of the accommodating sleeve 1 is formed with external threads. The accommodating sleeve 1 is screwed with a screwing member 11. The screwing member 11 is pressed against the inner side of the outer wall 5. The outer diameter of the screwing member 11 is larger than the inner diameter of the hole.

[0047] As shown in Figure 4 , the plugging assembly 3 is accommodated in the outer end of the accommodating sleeve 1 (initial state of the plugging assembly 3).

[0048] Specifically, the plugging assembly 3 comprises a collapsible umbrella frame 31 and a flexible umbrella cloth wrapped on the umbrella frame 31. The umbrella frame 31 is connected with the grouting pipe 2 through a connecting rope 32.

[0049] The driving assembly 4 is installed on the accommodating sleeve 1. The driving assembly 4 is used to push the plugging assembly 3 to the outer side of the outer wall 5.

[0050] As shown in Figure 1 , after the plugging assembly 3 is pushed to the outer side of the outer wall 5, the umbrella frame 31 is expanded so that the plugging assembly 3 is pressed against the outer side of the outer wall 5, so that the plugging assembly 3 closes the outer port of the hole. After the plugging assembly is expanded, the overall shape of the plugging assembly is conical. The conical bottom surface of the plugging assembly is pressed against the outer side of the outer wall to close the outer port of the hole. The grouting pipe and the plugging assembly respectively close the outer port and the inner port of the hole.

[0051] After the outer port of the hole is closed, the plugging material is poured into the hole and the accommodating sleeve 1 through the grouting pipe 2 to close the hole, and then the connecting rope 32 is cut off to separate the plugging assembly 3 from the outer wall 5.

[0052] As shown in Figure 1 , Figure 4 and Figure 5 , the umbrella frame 31 comprises a shaft 311, a spoke 312, a sliding sleeve 313 and a first elastic member.

[0053] The shaft 311 has opposite ends, wherein one end of the shaft 311 is connected with the connecting rope 32.

[0054] The number of the spokes 312 is multiple. One end of the spoke 312 is hinged to the other end of the shaft 311. The multiple spokes 312 are arranged along the circumferential direction of the shaft 311.

[0055] The sliding sleeve 313 is slidably arranged on the shaft 311. The sliding sleeve is movably arranged on the shaft and can slide along the axial direction of the shaft. The spokes 312 are hingedly connected with the sliding sleeve 313. When the sliding sleeve slides towards the other end of the shaft, the top support bar 314 will spread the spokes.

[0056] The first elastic member is arranged on the shaft 311. The first elastic member is used to push the sliding sleeve 313 towards the other end of the shaft 311 to spread the spokes 312. In this embodiment, the first elastic member is a spring.

[0057] As a preferred embodiment, a limiting member is arranged on the middle part of the shaft 311. The limiting member is arranged on the side of the sliding sleeve away from the connecting rope 32. The elastic member is connected between the limiting member and the sliding sleeve 313.

[0058] Referring to Figure 3 As shown, the driving assembly 4 includes a support 41, a pry plate 42, a compression spring 43 and a trigger 44.

[0059] The support 41 is arranged on the inner end of the accommodating sleeve 1. The support is arranged along the radial direction of the accommodating sleeve. The height of the support is smaller than the diameter of the accommodating sleeve.

[0060] The pry plate 42 is arranged along the axial direction of the accommodating sleeve. The middle part of the pry plate 42 is reversibly arranged on the support 41. The lower end of the pry plate 42 is formed with a pressure receiving plate 421.

[0061] The compression spring 43 is arranged on the side of the support 41 facing the plugging assembly 3. The compression spring is supported on the pressure receiving plate 421.

[0062] The trigger 44 is in a semi-spherical shape. The inner end of the accommodating sleeve 1 is formed with a through hole. The trigger 44 is slidably arranged in the through hole. One end of the trigger 44 extends into the accommodating sleeve 1. The upper end of the pry plate 42 is pressed against one end of the trigger 44. The outer diameter of the trigger gradually decreases from the end of the trigger close to the pry plate to the other end of the trigger away from the pry plate. The maximum outer diameter of the trigger is larger than the inner diameter of the through hole, and the minimum outer diameter of the trigger is smaller than the inner diameter of the through hole.

[0063] After pressing the trigger 44, the trigger 44 downwardly presses the upper end of the pry plate 42 to lift the lower end of the pry plate 42, so that the pressure receiving plate 421 is separated from the compression spring 43. The compression spring 43 is elongated to push the plugging assembly 3 to the outside of the outer wall 5, so that the umbrella frame 31 of the plugging assembly 3 is spread.

[0064] As a preferred embodiment, an elastic support is arranged between the side of the upper end of the pry plate away from the trigger and the accommodating sleeve.

[0065] The application provides a construction method of an umbrella-shaped frameless hole plugging device for assisting construction, and comprises the following steps.

[0066] S1, the accommodation sleeve 1 is arranged in the hole of the outer wall 5, so that the end surface of the grouting pipe 2 is pressed against the inner side of the outer wall 5 to close the inner port of the hole.

[0067] S2, the driving assembly 4 pushes the plugging assembly 3 to the outer side of the outer wall 5.

[0068] By pressing the trigger 44, the trigger 44 downwardly abuts against the upper end of the pry plate 42 to make the lower end of the pry plate 42 lift up, so that the pressure plate 421 is separated from the compression spring 43, the compression spring 43 is elongated to push the plugging assembly 3 to the outer side of the outer wall 5.

[0069] S3, after the plugging assembly 3 is pushed to the outer side of the outer wall 5, the umbrella frame 31 of the plugging assembly 3 is expanded to make the plugging assembly 3 press against the outer side of the outer wall 5, so that the plugging assembly 3 closes the outer port of the hole.

[0070] After the plugging assembly is separated from the accommodation sleeve, due to the lack of the constraint of the accommodation sleeve, the first elastic member pushes the sliding sleeve ring 313 towards the other end of the shaft 311 to make the plurality of spokes 312 expand, so that the plugging assembly forms a conical plugging member.

[0071] S4, after the outer port of the hole is closed, the plugging slurry is poured into the hole and the accommodation sleeve 1 through the grouting pipe 2 to plug the hole.

[0072] S5, the connecting rope 32 is cut off to make the plugging assembly 3 separate from the outer wall 5.
