Description

Technical Field

[0001] The utility model relates to the technical field of waterproof structures for construction joints in building construction, and particularly relates to a waterproof structure for construction joints in building construction. Background Technique

[0002] A construction joint refers to the joint surface formed between different pouring sections during the concrete pouring process due to limitations in pouring capacity or requirements of construction design, which requires segmented pouring. For the construction joint, waterproof treatment is needed mainly to prevent moisture, dampness, and other liquids from penetrating into the building structure, thereby protecting the stability and durability of the structure. Traditional waterproof measures for construction joints usually involve installing a water stop plate on the side of the construction joint close to the water-facing surface and filling waterproof fillers on the outer and inner sides of the water stop plate, so that the waterproof fillers can also fix the water stop plate in the construction joint. The water stop plate blocks the penetration of water to the inner side to achieve waterproofing of the construction joint. Although the water stop plate and waterproof fillers can play a waterproof role to a certain extent, after long-term use, the waterproof fillers located on the water-facing surface of the construction joint and directly in contact with the infiltrating water may crack, etc., causing the infiltrating water to penetrate into the construction joint and the building interior through the cracked gaps, resulting in a weakened waterproof performance at the construction joint. For this reason, the patent application No. 202321909376.5 relates to a waterproof structure for construction joints in building construction, which includes a waterproof member and waterproof fillers filled in the external construction joint. The waterproof member includes a water stop part, a waterproof part, and a connecting rod. One end of the connecting rod is fixedly connected to the water stop part, and the other end of the connecting rod is fixedly connected to the waterproof part. The waterproof part is embedded in the external wall, and the connecting rod is arranged in the construction joint. The bottom of the water stop part abuts against the water-facing surface of the external wall. This structure can reduce the impact of water seepage at the construction joint on the building and improve the waterproof performance at the construction joint;

[0003] The above-mentioned waterproof structure for construction joints in building construction disclosed in the patent can improve the waterproof performance by the bottom of the water stop part abutting against the water-facing surface of the external wall. In addition, a blocking strip is used for plugging at the construction joint. However, there are still some deficiencies in its use: 1. The size of the blocking strip is fixed. Due to the different sizes of the gaps in the construction joint, when the size of the blocking strip is small, it cannot effectively fit the construction joint, thus affecting its plugging and sealing effect. Although the blocking strip will expand when it meets water, the possibility of the waterproof material contacting water will increase after it meets water, which will affect its waterproof effect; 2. There is a lack of a structure for strengthening the waterproof material in the construction joint. Simply filling the waterproof material in the construction joint lacks the biting and strengthening force in the middle. After long-term use, the waterproof material will loosen and fall off; Considering the above situations, we have therefore proposed a waterproof structure for construction joints in building construction.

Through the setting of a series of structures in the present utility model, the extrusion force of the waterproof concrete material 1 and the elastic forces of the first elastic rubber tube 9 and the second elastic rubber tube 7 can be utilized to cause the first elastic rubber tube 9 and the second elastic rubber tube 7 to expand and closely fit with the construction joint 101, so that it can be applicable to construction joints 101 of different sizes, improving the scope of application and the sealing effect, and being able to reinforce and support the interior of the poured waterproof concrete material 1, effectively reducing the situation of the filled waterproof concrete material 1 becoming loose and falling off, and improving the stability during use.

[0026] Working principle: When in use, remove the four first blocking blocks 15, and fix the water baffle 5 on the water-facing surface on the right side of the two walls 100 through the four T-shaped fixing bolts 13. After fixing, block the corresponding T-shaped holes 14 with the first blocking blocks 15 to prevent subsequent rainwater from entering the corresponding T-shaped holes 14. At this time, the reinforcing ribs 2, the reinforcing rods 3, the barbs 4, the blocking plates 8, the second elastic rubber tubes 7 and the first elastic rubber tubes 9 are all located in the construction joint 101. Immediately afterwards, remove the two T-shaped blocking blocks 12 to remove the shielding of the two pouring pipes 11. At this time, the waterproof concrete material 1 can be injected into the second elastic rubber tube 7 through the two pouring pipes 11. The waterproof concrete material 1 inside the second elastic rubber tube 7 enters the construction joint 101 through the first discharge holes 17 and the second discharge holes 16 in sequence. The added waterproof concrete material 1 adheres to the reinforcing ribs 2, multiple reinforcing rods 3 and multiple barbs 4. When the waterproof concrete material 1 inside the construction joint 101 is full, the continuously added waterproof concrete material 1 squeezes the second elastic rubber tube 7. Under the extrusion force, the second elastic rubber tube 7 expands and is in close contact with the construction joint 101. At the same time, a part of the waterproof concrete material 1 inside the second elastic rubber tube 7 enters the two first elastic rubber tubes 9 through the four connecting pipes 10. The waterproof concrete material 1 entering the first elastic rubber tube 9 squeezes the first elastic rubber tube 9, causing the first elastic rubber tube 9 to expand and fit tightly with the inner wall of the construction joint 101. After the waterproof concrete material 1 is poured, the corresponding pouring pipes 11 can be blocked with the T-shaped blocking blocks 12, and the first elastic rubber tube 9 and the second elastic rubber tube 7 expand and fit tightly with the construction joint 101 by pouring the waterproof concrete material 1, achieving the effect of expanding the outer diameter, enabling it to be applicable to construction joints 101 of different sizes, improving the applicable range and sealing effect, and cooperating with the setting of the water baffle 5 and the water stop strip 6, which can effectively reduce the situation of rainwater entering the construction joint 101 and effectively improve the waterproof effect;

[0027] After the waterproof concrete material 1 inside the construction joint 101 solidifies, it can effectively bite with multiple reinforcing rods 3 and multiple barbs 4. Under the biting force, the filled waterproof concrete material 1 can be effectively reinforced inside, and the situation of the filled waterproof concrete material 1 loosening and falling off can be effectively reduced, improving the stability during use.

[0028] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
