Description

Technical Field

[0001] This utility model relates to the field of precast concrete technology, specifically to a lightweight precast concrete component that is easy to hoist and assemble. Background Technology

[0002] Lightweight precast concrete components are concrete components made of lightweight materials. They can also be made into high-strength C60 concrete components through appropriate material ratios. Compared with ordinary concrete components, they have advantages such as high strength and light weight. The components can be transported to the construction site for use after they are manufactured and cured.

[0003] The prior art (Chinese patent application number CN202321792645.4, published on January 2, 2024) discloses an easy-to-install precast concrete component, comprising a precast concrete component body and mounting rods. Mounting rods are installed on the sidewalls of one end of the precast concrete component body, and mounting blocks are installed on the sidewalls of the same end. Sealing blocks are installed on the outer walls of the mounting blocks. A first mounting groove is formed on the sidewall of the precast concrete component body away from the mounting rods, with sealing grooves at the top and bottom. A second mounting groove is formed on the sidewall of the precast concrete component body away from the mounting rods. This easy-to-install precast concrete component uses a sealing ring to engage with the sealing groove, and also utilizes the interlocking of the mounting blocks and the second mounting groove. The design of the sealing blocks facilitates insertion of the mounting blocks into the second mounting groove, thereby facilitating the splicing and installation of two sets of precast concrete component bodies by the operator.

[0004] Currently, after precast concrete components are manufactured, they are generally installed on the construction site by hoisting. When hoisting the components, hoisting points need to be set on the components, or hoisting hooks need to be pre-embedded during the production of the components. However, after the hoisting hooks are set, the outer surface of the components will be raised, which is not conducive to the subsequent placement and transportation of the components. Moreover, the raised splicing positions are also easily damaged, increasing the product loss rate. Utility Model Content

[0005] The purpose of this utility model is to provide a lightweight precast concrete component that is easy to lift and assemble, in order to solve the problem mentioned in the background art that currently, after the precast concrete components are manufactured, they are generally installed on the construction site by lifting. When lifting the components, lifting points need to be set on the components, or lifting hooks need to be pre-embedded during the production of the components. However, after the lifting hooks are set, the outer surface of the components will be raised, which is not conducive to the subsequent placement and transportation of the components, and the raised splicing positions are also easily damaged.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight precast concrete component that is easy to hoist and assemble, comprising a precast body, with embedded parts on the sides of the precast body and hollow columns fixed inside the embedded parts. Pairs of embedded parts are connected to each other through the hollow columns. The embedded parts have a mating interface inside, and splicing parts are nested inside the mating interface. The splicing parts and the mating interface form a detachable connection. Adjacent precast bodies are connected through the splicing parts, and a storage groove is provided inside the splicing parts. A hanging ring is provided inside the embedded parts to assist in the hoisting of the precast body. After the splicing parts are inserted into the mating interface, the storage groove provides storage space for the hanging ring.

[0007] To further optimize this technical solution, an adhesive pad is fixed to the outer side of the splicing component, and the adhesive pad is made of shock-absorbing material.

[0008] To further optimize this technical solution, the splicing component has a uniform through-hole inside, the embedded component has a connection port corresponding to the through-hole on its surface, and a connection mechanism is provided on the outside of the connection port to lock the splicing component and the embedded component.

[0009] To further optimize this technical solution, the connecting mechanism includes a positioning port, a locking component, an auxiliary head, and a connecting cap;

[0010] The positioning port is located on the front side of the connection port;

[0011] Locking element, penetrating the interior of the connector and through-hole;

[0012] An auxiliary head is fixed to the front end of the locking component, and an engagement structure is formed between the auxiliary head and the positioning port;

[0013] A connecting cap is located at the rear end of the locking member, and a threaded connection is formed between the connecting cap and the locking member.

[0014] To further optimize this technical solution, the inner end of the hanging ring is provided with an active mechanism, allowing the hanging ring to extend out of the interface.

[0015] To further optimize this technical solution, the movable mechanism includes a movable block. The inner end of the movable block has an enlarged structure design. The inner end of the movable block is located inside the hollow column and forms a horizontal sliding structure between the hollow column and the hollow column. The end opening of the hollow column is narrowed to limit the maximum movement distance of the movable block.

[0016] To further optimize this technical solution, a return spring is provided on the outer side of the movable block. The return spring provides a pushing force to the movable block to keep the hanging ring in the stored state.

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

[0018] (1) By setting embedded parts in the precast body, a foundation is provided for the subsequent splicing of the precast body. The embedded parts, together with the hollow columns, can also improve the internal crack resistance of the precast body and reduce the weight of the precast body. In addition, the precast body has a pre-reserved hanging ring inside, which makes subsequent lifting convenient. The hanging ring is hidden inside and does not affect the transportation and storage of the precast body.

[0019] (2) Adjacent prefabricated components are connected by splicing parts. The splicing parts and the interface are detachable. The splicing parts can be installed and used on the construction site, avoiding the splicing position from being easily damaged and facilitating the placement of the products.

[0020] (3) After the main body of the prefabricated component is assembled, the hanging ring can be put into the storage slot without disassembly. The hanging ring is movable and can be pulled out from the interface when in use, making it convenient to connect the hanging ring to the external lifting equipment. Attached Figure Description

[0030] Example 1

[0031] This embodiment provides a lightweight precast concrete component that is easy to hoist and assemble, such as... Figure 1-3 As shown, the device includes a precast body 1, with embedded parts 2 on the sides of the precast body 1. Hollow columns 12 are fixed to the inner sides of the embedded parts 2. Pairs of embedded parts 2 are connected to each other via the hollow columns 12. An interface 3 is provided inside the embedded part 2, and a splicing piece 4 is nested inside the interface 3. The splicing piece 4 and the interface 3 form a detachable connection, connecting adjacent precast body 1s. A storage groove 16 is provided inside the splicing piece 4, and a hanging ring 13 is provided inside the embedded part 2. Figure 2-3 As shown, the auxiliary prefabricated main body 1 is lifted, and the splicing part 4 is inserted into the interface 3. The storage groove 16 provides storage space for the hanging ring 13.

[0032] In this embodiment, the precast body 1 is provided with embedded parts 2 and hollow columns 12. Before pouring the precast body 1, the embedded parts 2 and hollow columns 12 can be placed so that the upper and lower surfaces of the embedded parts 2 are flush with the precast body 1. After pouring, the sides of the precast body 1 remain flush, which is convenient for storage and transportation. The precast body 1 can also be lifted with the hanging rings 13 in the embedded parts 2, making it more convenient to use.

[0033] Example 2

[0034] like Figure 4-5 As shown, a fitting pad 5 is fixed to the outer side of the splicing component 4. The fitting pad 5 is made of shock-absorbing material. A through-hole 6 is evenly distributed inside the splicing component 4. A connection port 7 corresponding to the through-hole 6 is formed on the surface of the embedded part 2. A connecting mechanism is provided on the outer side of the connection port 7 to lock the splicing component 4 and the embedded part 2. The connecting mechanism includes a positioning port 8, a locking element 9, an auxiliary head 10, and a connecting cap 11. The positioning port 8, as shown... Figure 4 As shown, a locking member 9 is opened on the front side of the connection port 7, passing through the interior of the connection port 7 and the through port 6. An auxiliary head 10 is fixed to the front end of the locking member 9, and the auxiliary head 10 and the positioning port 8 form an engaging structure. A connecting cap 11 is set at the rear end of the locking member 9, and the connecting cap 11 and the locking member 9 form a threaded connection.

[0035] When assembling the precast main body 1, the splicing piece 4 can first be inserted into the mating interface 3 in the embedded part 2, then the locking piece 9 can be passed through the positioning port 8 and the connecting port 7, and then the connecting cap 11 and the locking piece 9 can be connected to fix the splicing piece 4. Figure 5 As shown, the interface 3 of the adjacent prefabricated body 1 is then inserted into the other end of the splicing piece 4, and then fixed by the locking piece 9 and the connecting cap 11, thus completing the splicing of the prefabricated body 1.

[0036] Example 3

[0037] like Figure 6 As shown, the inner end of the hanging ring 13 is provided with a movable mechanism, which allows the hanging ring 13 to extend out of the interior of the interface 3. The movable mechanism includes a movable block 14. The inner end of the movable block 14 is designed to be enlarged. The inner end of the movable block 14 is located inside the hollow column 12 and forms a horizontal sliding structure between the hollow column 12 and the hollow column 12. The end opening of the hollow column 12 is designed to be narrowed, which limits the maximum movement distance of the movable block 14. A return spring 15 is provided on the outer side of the movable block 14. The return spring 15 provides a thrust to the movable block 14 to keep the hanging ring 13 in the retracted state.

[0038] By default, the hanging ring 13 is located inside the interface 3. When it is necessary to pull out the hanging ring 13 for use, the hanging ring 13 can be pulled, such as... Figure 1-6 As shown, the movable block 14 compresses the return spring 15, and the hanging ring 13 extends and can connect with the hook to lift the precast main body 1. After the lifting is completed, the tension on the hanging ring 13 is released, and the hanging ring 13 returns to the inside of the interface 3. During subsequent assembly, the storage groove 16 can provide storage space for the hanging ring 13. Figure 6 This description pertains to the lifting ring 13. During lifting, the lifting ring 16 is pulled out. The splicing does not involve the lifting ring 13; the splicing is performed using the splicing component 4. The structure of the splicing component 4 is as follows: Figure 5 As shown, two adjacent precast body 1s are connected, and the left and right ends of the splicing piece 4 are inserted into the adjacent precast body 1 respectively. (See top section image). Figure 4 As shown, the locking piece 9 is then passed through the through-hole 6, the connecting port 7 and the positioning port 8, and the locking piece 9 is tightened using the connecting cap 11 to complete the splicing.

[0039] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model to facilitate understanding and application by those skilled in the art. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of this utility model, without requiring creative effort. Therefore, any simple improvements made to this utility model by those skilled in the art based on its disclosure should be within the protection scope of this utility model.
