Description

Technical Field

[0001] This utility model relates to the field of precast concrete composite slabs, and more particularly to a vertical connection structure for precast concrete composite slabs. Background Technology

[0002] Precast concrete composite slabs, also known as precast concrete floor slabs or precast composite slabs, are concrete components that are prefabricated in a factory and assembled on the construction site. They are mainly used in building floor systems and are a commonly used component in modern architecture, especially suitable for high-rise buildings, industrial buildings, and residential projects.

[0003] Most existing precast concrete composite slabs do not have effective waterproofing structures at the vertical joints after splicing. This allows rainwater or moisture to easily penetrate into the slab through these joints, causing the slab to become damp and even leading to problems such as steel corrosion and concrete cracking. Furthermore, long-term water accumulation or moisture erosion can not only affect the durability of the structure but may also reduce the overall service life of the building.

[0004] Therefore, it is necessary to provide a vertical connection structure for precast concrete composite slabs to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a vertical connection structure for precast concrete composite slabs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a vertical connection structure for a precast concrete composite slab, including a slab body, a protective frame fixedly connected to one side of the slab body, a waterproof groove opened on one side of the protective frame, placement frames fixedly connected to both sides of the inner wall of the protective frame, a number of vents opened on all four sides of the placement frames, a desiccant placed at the bottom of the inner wall of the placement frames, a sealing ring fixedly connected to the other side of the slab body, a number of insertion components provided on the side of the slab body near the placement frames, a number of snap-fit ​​components provided on the side of the slab body away from the placement frames, a number of bolts threaded through the top of the placement frames, and a protective component provided at the top of the bolts.

[0007] By setting up snap-fit ​​components and insertion components and using bolts, two plates can be spliced ​​together. At this time, the sealing ring will snap into the inside of the waterproof groove, thereby preventing moisture and rainwater from entering the interior of the placement frame. Meanwhile, the dryer and vent can be used to dry the rainwater and moisture that enter the interior of the placement frame.

[0008] The insertion assembly includes an insertion block fixedly connected to one side of the plate, and the top of the insertion block has a threaded groove.

[0009] The threaded groove is adapted to the bolt.

[0010] The snap-fit ​​assembly includes a snap-fit ​​block fixedly connected to one side of the plate body, a snap-fit ​​interface fixedly connected to one side of the snap-fit ​​block, and a threaded hole opened on the top of the snap-fit ​​block.

[0011] By setting up snap-fit ​​blocks and snap-fit ​​interfaces and using insert blocks, two boards can be precisely spliced ​​together.

[0012] The size inside the threaded hole is the same as the size inside the threaded groove.

[0013] The protective component includes a protective sleeve fitted onto the top of the bolt, and an installation groove is provided at the bottom of the protective sleeve. A waterproof ring is fixedly connected to the inner wall of the installation groove.

[0014] By setting a waterproof ring, the bolts can be waterproofed after they are fixed together with the insertion block and the snap-fit ​​block.

[0015] The waterproof ring is made of polyurethane.

[0016] The sealing ring is made of rubber.

[0017] Compared with the prior art, the beneficial effects of this utility model include:

[0018] 1. By using a combination of structures such as protective frames, waterproof grooves, placement frames, vents, desiccants, sealing rings, insertion components, snap-fit ​​components, and bolts, waterproofing can be carried out at the joint after two panels are spliced ​​together. This prevents external rainwater and moisture from seeping into the interior of the panels through the joint, thus preventing internal dampness and steel corrosion and concrete cracking. This increases the durability of the precast concrete composite slab and improves the overall service life of the building.

[0019] 2. By setting up protective components, the bolts can be effectively waterproofed, preventing damage from moisture, corrosive substances, or other external environmental factors, thereby reducing problems such as rust and wear, preventing bolt loosening, and improving the service life of the bolts.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] According to one embodiment of the present invention, in conjunction with Figure 1-4 The diagram illustrates a vertical connection structure for a precast concrete composite slab, comprising a slab body 1, a protective frame 2 fixedly connected to one side of the slab body 1, a waterproof groove 3 formed on one side of the protective frame 2, placement frames 4 fixedly connected to both sides of the inner wall of the protective frame 2, several vents 5 formed on all four sides of the placement frames 4, a desiccant 6 placed at the bottom of the inner wall of the placement frames 4, a sealing ring 7 fixedly connected to the other side of the slab body 1, several insertion components provided on the side of the slab body 1 near the placement frames 4, several snap-fit ​​components provided on the side of the slab body 1 away from the placement frames 4, and several bolts 8 threaded through the top of the placement frames 4, with the top of the bolts 8... A protective component is provided. The sealing ring 7 is made of rubber. The size of the sealing ring 7 is the same as the size of the inside of the waterproof groove 3. The position of the sealing ring 7 is the same as the position of the waterproof groove 3. Several snap-fit ​​components and several insertion components are in the same position. The protective component is used to protect the bolt 8. By setting the snap-fit ​​components and insertion components and cooperating with the bolt 8, the two plates 1 can be spliced ​​together. At this time, the sealing ring 7 will be snapped into the inside of the waterproof groove 3, thereby preventing moisture and rainwater from entering the inside of the placement frame 4. At the same time, the dryer and the vent 5 can be used to dry the rainwater and moisture that enter the inside of the placement frame 4.

[0028] By using a combination of structures such as protective frame 2, waterproof groove 3, placement frame 4, vent 5, desiccant 6, sealing ring 7, insertion component, snap-fit ​​component, and bolt 8, waterproofing can be carried out at the joint after two panels 1 are spliced ​​together. This prevents external rainwater and moisture from seeping into the interior of the panels through the splice seam, thus preventing internal dampness and steel corrosion and concrete cracking. This increases the durability of the precast concrete composite slab and improves the overall service life of the building.

[0029] The insertion assembly includes an insertion block 9 fixedly connected to one side of the plate 1. The top of the insertion block 9 is provided with a threaded groove 10, which is adapted to the bolt 8.

[0030] The snap-fit ​​assembly includes a snap-fit ​​block 11 fixedly connected to one side of the plate 1. A snap-fit ​​interface 12 is fixedly connected to one side of the snap-fit ​​block 11. A threaded hole 13 is provided on the top of the snap-fit ​​block 11. By setting the snap-fit ​​block 11 and the snap-fit ​​interface 12 and using the insertion block 9, the two plates 1 can be precisely spliced ​​together. The size inside the threaded hole 13 is the same as the size inside the threaded groove 10.

[0031] The protective component includes a protective sleeve 14 fitted onto the top of the bolt 8. The bottom of the protective sleeve 14 has an installation groove 15. A waterproof ring 16 is fixedly connected to the inner wall of the installation groove 15. The waterproof ring 16 is made of polyurethane material. By setting the waterproof ring 16, the bolt 8 can be waterproofed after the bolt 8 fixes the insertion block 9 and the snap-fit ​​block 11 together.

[0032] In this embodiment, during use, the protective frame 2 on one plate 1 is first aligned with the sealing ring 7 on the other plate 1. Then, the two plates 1 are joined together so that the insertion block 9 is engaged in the locking interface 12 on the locking block 11. Then, the protective sleeve 14 on the bolt 8 is rotated so that the bolt 8 enters the threaded groove 10 through the threaded hole 13 on the locking block 11, thereby fixing the insertion block 9 inside the locking interface 12 and completing the splicing work between the two plates 1. At this time, the sealing ring 7 will be engaged inside the waterproof groove 3, so that the sealing ring 7 and the waterproof groove 3 can prevent external rainwater and moisture from entering the interior of the protective frame 2. Then, the desiccant 6 and the vent 5 can be used to dry the rainwater and moisture that enter the interior of the protective frame 2. After the splicing work of the two plates 1 is completed, the protective sleeve 14 and the waterproof ring 16 can be used to waterproof the threads.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
