Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a novel grouting sleeve and a use method thereof. Background Art

[0002] At present, with the development of modular buildings, prefabricated buildings occupy an increasingly larger share in the construction field. However, in traditional construction, hard straight tubes or soft corrugated pipes are used as grouting sleeves, and rubber plugs are used for grouting plugging. In the construction of prefabricated components, soft corrugated pipes are easily crushed by concrete, which makes it difficult to grout in the later stage. The straight tube grouting sleeve has the problem of incomplete grouting caused by slurry leakage from the slurry hole when the grouting machine is evacuated after the grouting is completed. When using a rubber plug to seal the sleeve, not only does it require a hammer or other tools to force the rubber plug into the sleeve during construction, but it is often difficult to control the quality of the plugging, causing it to fall off and lead to slurry leakage. Summary of the invention

[0003] The purpose of the present invention is to provide a new type of grouting sleeve and a method of using the same, so as to avoid the problem of grout leakage caused by incomplete grouting and poor sealing quality of grouting plugs during grouting construction of prefabricated components, and facilitate the rapid and efficient grouting work during grouting construction.

[0004] To achieve the above object, the present invention provides a novel grouting sleeve, comprising a grouting pipe connected to a steel bar connection sleeve, a grouting plug cover and a plugging device, wherein the plugging device is connected to the grouting plug cover, and the grouting plug cover is connected to the grouting pipe;

[0005] The grouting pipe is arranged as a curved structure, and the connecting end of the grouting pipe is arranged with an external thread;

[0006] The grouting plug cover comprises a cylinder and an end cover connected to the cylinder, the end cover is fixed to the free end of the cylinder, a first grout outlet hole is arranged on the end cover, and an internal thread adapted to the external thread is arranged on the inner side of the connecting end of the cylinder;

[0007] The blocking device comprises a blocking inner cover, a connecting shaft arranged at the center of the blocking inner cover, and a rotating knob fixed at the outer end of the connecting shaft, wherein the blocking inner cover is arranged on the inner side of the end cover, and the diameter of the blocking inner cover is smaller than the inner diameter of the cylinder;

[0008] The blocking inner cover is provided with a second pulp outlet hole.

[0009] Preferably, the first slurry outlet hole and the second slurry outlet hole are arc-shaped structures, and are both arranged on one side of the connecting shaft.

[0010] Preferably, a through hole adapted to the connecting shaft is provided at the center of the end cover.

[0011] Preferably, the grouting pipe is made of hard PVC.

[0012] A method for using a novel grouting sleeve comprises the following steps:

[0013] (1) Install the grouting pipe at the predetermined location, and then bring the components to the site and install them;

[0014] (2) After the components are delivered and installed, the plugging device is installed on the grouting plug cap, and then the grouting plug cap is installed on the grouting pipe pre-buried in the component, and the internal thread of the grouting plug cap is screwed onto the external thread of the grouting pipe. After the overall installation is completed, the grouting operation is carried out;

[0015] (3) The operator rotates the connecting shaft by means of a rotary knob, and the connecting shaft drives the plugging inner cover to rotate. When the plugging inner cover rotates until the second slurry outlet hole completely overlaps with the first slurry outlet hole, the operator stops rotating and starts grouting from the grouting hole. When the grouting material is filled and overflows from the first slurry outlet hole on the grouting plug cover, the operator stops grouting. Then, the operator rotates the connecting shaft by means of a rotary knob from bottom to top, and the connecting shaft drives the plugging inner cover to rotate. When the plugging inner cover rotates until the second slurry outlet hole does not overlap with the first slurry outlet hole, the plugging inner cover blocks the first slurry outlet hole. Then, the operator stops rotating and the grouting plugging is completed.

[0016] Therefore, the present invention adopts a new type of grouting sleeve with the above structure and its use method to avoid the grouting leakage problem caused by incomplete grouting and poor sealing quality of grouting plugs during the grouting construction of prefabricated components, and facilitates the rapid and efficient grouting work during the grouting construction.

[0021] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0022] Example

[0023] Figure 1 This is an exploded view of a new type of grouting sleeve of the present invention. Figure 2 This is a schematic diagram of the structure of a new type of grouting sleeve of the present invention. Figure 3The present invention provides a new type of grouting sleeve assembly structure schematic diagram, as shown in the figure, the present invention provides a new type of grouting sleeve, including a grouting pipe 2 connected to a steel bar connecting sleeve 1, a grouting plug cover 3 and a plugging device 4, the plugging device 4 is connected to the grouting plug cover 3, and the grouting plug cover 3 is connected to the grouting pipe 2; the grouting pipe 2 is set as a curved structure, and the connecting end of the grouting pipe 2 is provided with an external thread 5; the grouting plug cover 3 includes a cylinder 31 and an end cover 32 connected to the cylinder 31, and the end cover 3 2 is fixed to the free end of the cylinder 31, a first slurry outlet hole 33 is arranged on the end cover 32, and an internal thread adapted to the external thread 5 is arranged on the inner side of the connecting end of the cylinder 31; the plugging device 4 includes a plugging inner cover 41, a connecting shaft 42 arranged at the center of the plugging inner cover 41, and a rotating knob 43 fixed to the outer end of the connecting shaft 42, the plugging inner cover 41 is arranged on the inner side of the end cover 32, and the diameter of the plugging inner cover 41 is smaller than the inner diameter of the cylinder 31; a second slurry outlet hole 44 is arranged on the plugging inner cover 41. The first slurry outlet hole 33 and the second slurry outlet hole 44 are arc-shaped structures, and are both arranged on one side of the connecting shaft 42. A through hole 6 adapted to the connecting shaft 42 is arranged at the center of the end cover 32. The material of the grouting pipe 2 is hard PVC. The grouting pipe of the present invention is made of hard PVC material to form a curved structure, so that the grouting material level is higher than the design requirement after grouting is completed, which solves the problem of incomplete grouting caused by slurry leakage from the outlet hole when the grouting machine is evacuated after the grouting is completed; by providing a grouting plug cover and a sealing device, compared with the traditional process, it is no longer necessary to cooperate with tools such as hammers, and the grouting pipe can be sealed by directly rotating the rotating knob.

[0024] A method for using a novel grouting sleeve comprises the following steps:

[0025] (1) Install the grouting pipe at the predetermined location, and then bring the components to the site and install them;

[0026] (2) After the components are delivered and installed, the plugging device is installed on the grouting plug cap, and then the grouting plug cap is installed on the grouting pipe pre-buried in the component, and the internal thread of the grouting plug cap is screwed onto the external thread of the grouting pipe. After the overall installation is completed, the grouting operation is carried out;

[0027] (3) The operator rotates the connecting shaft by means of a rotary knob, and the connecting shaft drives the plugging inner cover to rotate. When the plugging inner cover rotates until the second slurry outlet hole completely overlaps with the first slurry outlet hole, the operator stops rotating and starts grouting from the grouting hole. When the grouting material is filled and overflows from the first slurry outlet hole on the grouting plug cover, the operator stops grouting. Then, the operator rotates the connecting shaft by means of a rotary knob from bottom to top, and the connecting shaft drives the plugging inner cover to rotate. When the plugging inner cover rotates until the second slurry outlet hole does not overlap with the first slurry outlet hole, the plugging inner cover blocks the first slurry outlet hole, and then stops rotating to complete the grouting plugging. After the grouting is completed, the pressure of the slurry in the grouting tube itself prevents the plugging device from moving back, thereby solving the problem of plugging falling off due to poor quality of plugging that is difficult to control, and further causing slurry leakage.

[0028] Therefore, the present invention adopts a new type of grouting sleeve with the above structure and its use method to avoid the grouting leakage problem caused by incomplete grouting and poor sealing quality of grouting plugs during the grouting construction of prefabricated components, and facilitates the rapid and efficient grouting work during the grouting construction.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
