Description

Technical Field

[0001] This invention relates to the field of building waterproof connection node construction technology, specifically a prefabricated building waterproof connection node construction. Background Technology

[0002] Waterproof wall panels are a type of exterior wall panel used for waterproofing and protecting building exteriors. They consist of precast concrete panels and their connecting components or joints with the main structure. Installed on the main structure, they are non-load-bearing components that serve an enclosure and decorative function. Existing wall panel connection structures primarily use bolts to connect the wall panel to the connecting components during fixing. However, exterior wall panels are frequently subjected to impacts or collisions, causing vibrations that can loosen the bolts, leading to a gradual decrease in the connection strength of the exterior wall panels.

[0003] In addition, the joints between existing exterior wall panels are generally sealed with sealant. However, after a certain period of time, due to environmental factors, the sealant may age, break, or fall off, allowing rainwater to seep into the other side from the wall panel joints on rainy days, thus affecting the waterproofing effect.

[0004] Therefore, how to design a waterproof connection node structure for prefabricated buildings to achieve rapid and stable installation of waterproof wall panels and good sealing between waterproof wall panels has become an urgent problem to be solved in the current construction industry.

[0027] In one embodiment, the driving component 302 includes an end panel 3021, a limiting block 3022, a bushing 3023, a second threaded rod 3024, and a threaded sleeve 3025. A sleeve hole 3026 is formed between two adjacent sets of I-beams 3011, and a bushing 3023 is fitted into the sleeve hole 3026. One end of the bushing 3023 is fixedly connected to the end panel 3021. The end panel 3021 is in contact with the outer surface of the I-beam 3011. Two sets of symmetrical limiting blocks 3022 are fixedly connected between 3021 and the bushing 3023. A limiting groove 3028 is formed on the I-shaped plate 3011 opposite to the limiting block 3022. The limiting block 3022 is fitted into the limiting groove 3028.

The other ends of the push-pull rods 303 are respectively connected to the drive shaft 400. When the operating block 3029 is rotated by the wrench, the operating block 3029 drives the second screw to rotate. The second screw drives the threaded sleeve 3025 to move to one side of the wall. During this process, the two sides of the threaded sleeve 3025 pull the transmission shaft 400 closer to each other through the push-pull rod 303. The transmission shaft 400 drives the installation component 203 and the waterproof wall panel 100 closer to each other, so that the waterproof wall panel 100 is inserted and connected in the slots 3014 on both sides of the I-beam 3011.

[0029] This invention provides a waterproof connection node structure for prefabricated buildings, and its specific installation steps are as follows: Step 1: First, install and fix the wall connectors 202 to the wall surface one by one using expansion bolts. The wall connectors 202 are arranged in an array. Then, starting from the bottom of the wall, install the waterproof wall panels 100 one by one from bottom to top and from one side in the horizontal direction. Step two: When installing the waterproof wall panel 100 on one side of the wall, directly insert the first threaded rod 2012 on one side of the waterproof wall panel 100 into the corresponding mounting assembly 203 on the edge side. Then, push the waterproof wall panel 100 in parallel. During the movement of the waterproof wall panel 100, the mounting assembly 203 moves together, and the transmission shaft 400 between the mounting assemblies 203 moves together. This causes the transmission gears 110 at both ends of the transmission shaft 400 to rotate under the action of the rack 120. The transmission gears 110 drive the transmission shaft 400 to rotate, which in turn drives the worm 2034 to rotate. The worm 2034 drives the worm wheel 2039 to rotate, which in turn drives the outer sleeve 2032 to rotate. The outer sleeve 2032 drives the inner sleeve 2033 to rotate relative to each other through a unidirectional motion mechanism, so that the inner sleeve 2033 and the first threaded rod 2012 are threadedly connected to each other, thus completing the sequential installation process of the first row of waterproof wall panels 100. Step 3: By connecting the third threaded rod 130 and the push-pull rod 303 with each other, the drive unit 302 is installed and connected to the drive shafts 400 adjacent to the first and second columns respectively. Then, the first threaded rod 2012 of the waterproof wall panel 100 is inserted into the mounting assembly 203 of the second column respectively, and I-shaped seals 301 are installed between the waterproof wall panel 100 of the first column and the waterproof wall panel 100 of the first column. The drive unit 302 is then installed and fixed between the adjacent I-shaped seals 301. Step four: Rotate the operating block 3029 with a wrench. The operating block 3029 drives the second threaded rod 3024 to rotate. The second threaded rod 3024 drives the threaded sleeve to move relative to it. The threaded sleeve drives the transmission shaft 400 of the second column to move towards the waterproof wall panel 100 of the first column through the push-pull rod 303. The transmission shaft of the second column drives the installation component 203 and the waterproof wall panel 100 of the second column to move towards the waterproof wall panel 100 of the first column, so that the waterproof wall panel 100 of the first column and the waterproof wall panel 100 of the second column are relatively fitted and connected in the I-shaped seal 301. At the same time, the first threaded rod 2012 of the second column waterproof wall panel 100 is threadedly fixed to the installation component 203. The principle is the same as in step one. In this way, the waterproof wall panels 100 of the third column, fourth column, etc. are installed in sequence until all the waterproof wall panels 100 on the outer side of the front body are installed.
