Description

Technical Field

[0001] This utility model relates to the field of precast component technology, specifically a precast concrete component. Background Technology

[0002] With the acceleration of the industrialization of construction, precast concrete components have been widely used in the field of construction engineering due to their advantages such as high construction efficiency, stable quality, energy saving and environmental protection. In actual construction, precast concrete components often need to be spliced ​​and combined to meet different building structure requirements.

[0003] In terms of precast component splicing, traditional splicing methods rely heavily on additional auxiliary support devices, such as bolts, welding, or temporary support structures. These methods are not only cumbersome to install, requiring significant time and labor costs, but also necessitate the removal and handling of these auxiliary support devices after installation, further increasing the construction period and costs. In addition, gaps are generated at the splicing points of adjacent precast components, and material overflows from the joints during filling, resulting in material waste, increased construction costs, and uneven surfaces on the precast components, affecting the building's aesthetics and subsequent construction procedures. Therefore, a precast concrete component is needed to solve the problems existing in current technologies. Utility Model Content

[0004] The purpose of this invention is to provide a precast concrete component to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precast concrete component, comprising a first precast slab and a second precast slab, the second precast slab being disposed on one side of the first precast slab, and two sets of splicing mechanisms being provided between the opposite surfaces of the first and second precast slabs, the splicing mechanism comprising a sealing cover plate, a joint filling mold, and an anti-detachment clamping plate, the two sets of sealing cover plates being respectively fixed to the end faces of the first and second precast slabs, the sealing cover plate having a joint filling mold inside, and the sealing cover plate having an anti-detachment clamping plate slidably connected inside.

[0006] Preferably, overflow ports are provided on both sides of the joint between the first precast slab and the second precast slab, and the overflow ports are connected to the joint filling mold opening.

[0007] Preferably, the sealing cover has an internal receiving groove, and the anti-detachment plate is slidably connected in the receiving groove of the sealing cover.

[0008] Preferably, the side surface of the sealing cover is provided with a guide groove, and a guide slider is fixed on one side surface of the anti-detachment plate, the guide slider being slidably connected in the guide groove of the sealing cover.

[0009] Preferably, an anti-detachment groove is formed on one side surface of the first precast plate and the second precast plate, and the anti-detachment plate fits into the anti-detachment groove.

[0010] Preferably, the upper surface of the anti-detachment plate is provided with an anti-slip groove, and the first precast plate, the second precast plate and the sealing cover plate are arranged along the same vertical plane.

[0011] This utility model provides a precast concrete component, which has the following advantages compared with the prior art:

[0012] The designed splicing mechanism, utilizing the anti-detachment clamping plate and anti-detachment groove, allows for rapid locking after the first and second precast slabs are joined, reducing reliance on additional auxiliary support devices, improving installation efficiency, and effectively preventing relative displacement between precast slabs. This enhances the overall structural stability and reduces the risk of structural damage caused by loose connections. During disassembly or maintenance, simply removing the anti-detachment clamping plate from the anti-detachment groove easily releases the precast slab from its locked state, facilitating the replacement or repair of individual precast slabs without affecting the structural safety of other precast slabs. This significantly improves the flexibility and convenience of later maintenance of precast components.

[0013] By setting up a sealing cover plate and a joint filling mold, the sealing cover plate forms a joint filling mold with the precast slab. When filling the joint gap, the sealing cover plate plays a good sealing role, which can reduce the waste caused by material overflowing from the joint of the precast component. At the same time, it can prevent changes in the flatness of the precast component due to material overflow, thus ensuring the construction quality. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a precast concrete component, including a first precast slab 1 and a second precast slab 2. The first precast slab 1 and the second precast slab 2 serve as the basic structure of the precast concrete component, undertaking the main load transfer and structural support functions. Multiple precast slabs are quickly connected through a splicing mechanism to form a complete building component. The second precast slab 2 is located on one side of the first precast slab 1. Two sets of splicing mechanisms 3 are provided between the opposite surfaces of the first precast slab 1 and the second precast slab 2. The splicing mechanism 3 includes a sealing cover plate 4, a joint filling mold 5, and an anti-detachment clamping plate 7. The two sets of sealing cover plates 4 are respectively fixed to the end faces of the first precast slab 1 and the second precast slab 2. The sealing cover plate 4 has a joint filling mold 5 inside, and the anti-detachment clamping plate 7 is slidably connected inside the sealing cover plate 4. The splicing mechanism 3 connects the first precast slab 1 and the second precast slab 2, achieving rapid positioning, locking, and sealing, improving installation efficiency and ensuring connection strength.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that overflow ports 6 are provided on both sides of the joint between the first precast slab 1 and the second precast slab 2. The overflow ports 6 are connected to the joint filling mold 5. The sealing cover plate 4 has a receiving groove 8 inside. The anti-detachment plate 7 is slidably connected in the receiving groove 8 of the sealing cover plate 4.

[0022] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the side surface of the sealing cover plate 4 is provided with a guide groove 10, and the side surface of the anti-detachment plate 7 is fixed with a guide slider 9. The guide slider 9 is slidably connected in the guide groove 10 of the sealing cover plate 4. The side surface of the first precast plate 1 and the second precast plate 2 is provided with an anti-detachment groove 12. The anti-detachment plate 7 fits into the anti-detachment groove 12. The sealing cover plate 4 covers the front and rear sides of the joint of the precast plate, forming the outer boundary of the joint filling mold 5, preventing the joint filling material from overflowing, reducing material waste and surface flatness issues.

[0023] Further as Figure 1As shown, it is worth noting that the upper surface of the anti-detachment clamping plate 7 is provided with an anti-slip groove 11. The first precast slab 1, the second precast slab 2, and the sealing cover plate 4 are arranged along the same vertical plane. The anti-detachment clamping plate 7 slides into the anti-detachment groove 12 to rigidly lock the first precast slab 1 and the second precast slab 2, reducing the reliance on auxiliary support devices, enhancing overall stability, and preventing loosening of the connection due to vibration or load. In addition, the anti-detachment clamping plate 7 can be unlocked by moving outward through the anti-slip groove 11, which facilitates the individual disassembly or repair of a certain precast slab without affecting other components.

[0024] This solution has the following working process: During installation, the first precast slab 1 and the second precast slab 2 are positioned and connected through two splicing mechanisms 3 on opposite sides. Then, the anti-detachment plate 7 is pushed inward from the anti-slip groove 11, which drives the anti-detachment plate 7 into the corresponding anti-detachment groove 12. This can lock the first precast slab 1 and the second precast slab 2 in time after the connection construction, which can reduce the reliance on additional auxiliary support devices. The locking of the connection state of the first precast slab 1 and the second precast slab 2 can prevent relative displacement, enhance the overall stability of the structure, and reduce the risk of structural damage due to loose connection. When it is necessary to disassemble or maintain the precast slab, simply move the anti-detachment plate 7 outward from the anti-slip groove 11 to release it from the anti-detachment groove 12, which can release the locking state of the two precast slabs, making it convenient to replace or repair individual precast slabs without affecting the structural safety of other precast slabs.

[0025] After multiple precast slabs are installed together, the sealing cover plate 4 covers the front and rear sides of two adjacent precast slabs. Since the sealing cover plate 4 on the front and rear sides, the first precast slab 1 and the second precast slab 2 form a joint filling mold 5, the joint filling material can be injected into the joint filling mold 5 to fill the joint gap between the first precast slab 1 and the second precast slab 2. The sealing cover plate 4 can play a sealing role in the process of filling the joint between the first precast slab 1 and the second precast slab 2, thereby reducing the trouble of material waste and changes in the flatness of the precast parts caused by the overflow of the joint filling material.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
