[0002] Prefabricated concrete construction has become a trend in the construction industry and has been implemented for many years. Grouting connection is currently the only connection method in prefabricated buildings and is crucial for ensuring the overall connectivity and stability of the building structure. Since grouting is required at the bottom of prefabricated walls, the gaps at the bottom of the walls must be sealed in advance.

[0003] Existing sealing materials and tools make it difficult to accurately control the grouting cross-section, resulting in wet work due to sealing and leaving behind construction waste that cannot be recycled. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments.

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution;

[0007] Construction materials and tools for rapid sealing of grouting joints in prefabricated buildings;

[0008] This includes a grout-stopping strip that is attached to the grouting joint of a building. The side of the grout-stopping strip that is attached to the grouting joint is called the attaching side, and the side opposite to the attaching side is called the pressing side.

[0035] The side pressing portion 31 abuts against the outside of the pressure strip 2, and the upper pressing portion 32 abuts against the upper side of the grout stop strip 1.

[0036] The above design, by setting the grout-stop strip 1, can fill the gaps in the prefabricated wall surface, accurately control the grouting section, greatly improve the grouting quality, and reduce wet work; secondly, the pressure strip 2 can help to tighten the grout-stop strip 1 to prevent leakage during cement grouting; finally, by setting the clamping mechanism, the clamping mechanism can tighten the pressure strip 2 through the pressure plate 3, or the pressure plate 3 can be loosened to remove the pressure strip 2 and the grout-stop strip 1 from the wall surface for reuse, without leaving construction waste and can be recycled, making it more environmentally friendly.

[0037] Grout stop strip 1 is a sealing material widely used in construction engineering. It is mainly used to prevent grout leakage during concrete pouring, grouting and other construction processes, and to ensure the sealing and stability of the structure.

[0040] The width of the upper pressing part 32 is greater than the width of the pressing strip 2 but less than the total width of the pressing strip 2 and the grout-stopping strip 1; the difference between the width of the upper pressing part 32 and the total width of the pressing strip 2 and the grout-stopping strip 1 is 0.4-0.8cm; the height of the extended structure is 8-15cm; ensuring that the grout-stopping strip 1 can be pressed tightly by the pressing strip 2 and the pressing plate 3.

[0041] When using this product, clean the dust and grout from the base of the wall. Place the grout-stopping strip 1 in the gap at the base of the wall, straight and close to the wall. Press the grout-stopping strip 1 down with the pressure strip 2. Then, use bolts 6 to fix the pressure plate 3 onto the threaded sleeve 4. Finally, check if the grout-stopping strip 1 is compacted. Tighten the bolts 6 and the pressure plate 3 to press down the pressure strip 2. The grout-stopping strip 1 is pressed tightly by the pressure strip 2 and the pressure plate 3.

Secondly, the pressure strip 2 can help to tighten the grout-stop strip 1 and prevent leakage of the grout-stop strip 1 during cement grouting. Finally, by setting the clamping mechanism, the clamping mechanism can tighten the pressure strip 2 through the pressure plate 3, or the pressure plate 3 can be loosened to remove the pressure strip 2 and the grout-stop strip 1 from the wall surface for reuse, without leaving construction waste and can be recycled, which is more environmentally friendly. Example 2

[0042] refer to Figure 1 and Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0043] The threaded sleeve 4 is provided with a through hole that passes through the peripheral side of the threaded sleeve 4. The threaded sleeve 4 is provided with two through holes, which are located at both ends of the threaded sleeve 4 respectively. An anchoring steel bar 5 is inserted into the through hole of the threaded sleeve 4 away from the connecting part 33. The anchoring steel bar 5 is provided to prevent the threaded sleeve 4 from loosening or being pulled out, and to ensure that the grout stop strip 1 is pressed tightly to prevent grout leakage.

[0044] The clamping mechanism also includes a clamping strip 8 placed between the building wall and the pressure plate 3, and the clamping strip 8 is positioned above the bolt 6; by setting the clamping strip 8, the clamping force of the pressure plate 3 can be increased, ensuring that the grout-stopping strip 1 is clamped.

[0045] The clamping strip 8 is provided on the pressure strip 2, which is a channel steel structure. The pressure strip 2 has a channel steel structure with the opening direction of the channel steel structure facing the side clamping part 31; this saves material while ensuring the structural strength of the pressure strip 2.

[0046] It also includes a triangular wedge 7, which is inserted between the pressure strip 2 and the pressure plate 3; the width of the wedge 7 is less than the width of the groove, and the highest part of the wedge 7 is greater than the depth of the groove; if grout leakage occurs, the wedge 7 can be used to stop the leakage. After grouting is completed, it is left to stand until the grout material sets. The operation is simple and efficient.

[0047] When in use, the grout-stopping strip 1 fills the gaps in the prefabricated wall surface. The anchoring steel bars 5 in the wall prevent the threaded sleeve 4 from loosening or being pulled out, ensuring the clamping force of the grout-stopping strip 1 and preventing grout leakage. By setting the clamping strip 8, the clamping force of the pressure plate 3 can be further increased, ensuring that the grout-stopping strip 1 is clamped. The pressure strip 2 with a channel steel structure saves materials while ensuring the structural strength of the pressure strip 2. If grout leakage occurs, a wedge 7 is inserted between the pressure strip 2 and the pressure plate 3. The clamping force of the pressure strip 2 by the pressure plate 3 is increased, which can stop the grout leakage. After grouting is completed, it is left to stand until the grout material sets. The operation is simple and efficient.
