Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated concrete component splicing structure. Background Technology

[0002] In the modern construction industry, precast concrete components are widely used due to their advantages such as fast construction speed and strong quality control. However, traditional splicing methods for precast concrete components often have some problems, such as cumbersome splicing process, difficulty in ensuring splicing accuracy, and insufficient structural strength after splicing. In particular, ensuring precise docking and stable connection between precast concrete walls during the splicing process has always been a key focus for technicians.

[0003] Existing splicing methods mostly employ bolt connections and welding, but these methods are not only difficult and costly to construct, but also prone to stress concentration at the splice points, affecting the stability and durability of the overall structure. Furthermore, some splicing methods require extensive on-site processing and installation work, which is not only inefficient but also increases the risk of safety accidents. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated concrete component splicing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated concrete component splicing structure, including a splicing frame installed between two prefabricated concrete walls. Both ends of the splicing frame are integrally formed with wing plates, and the two ends of the wing plates are respectively inserted into the surfaces of the two prefabricated concrete walls. Both ends of the wing plates are provided with mounting grooves, and clamping blocks are inserted into the surfaces of the mounting grooves. A turntable is rotatably connected inside the mounting grooves. The surface of the turntable is provided with notches. After the notches and clamping blocks are misaligned, the turntable squeezes the clamping blocks to clamp the prefabricated concrete walls.

[0006] Preferably, the splicing frame has a square frame structure, the groove of the splicing frame is used for pouring concrete, and the width of the wing plate is greater than the width of the splicing frame.

[0007] Preferably, both sides of the splicing frame are integrally formed with a limiting frame, which is square and is inserted into the inside of the slot, which is located at the end of the precast concrete wall.

[0008] Preferably, the precast concrete wall has assembly slots on both sides, and the ends of the wing plates are inserted into the assembly slots.

[0009] Preferably, the installation groove is a circular groove, and there are four installation grooves, which are respectively distributed at the four corners of the wing plate. Two jacks are provided on the surface of the installation groove. The clamping blocks and the jacks correspond one by one, and the clamping blocks are movably inserted into the jacks. Two arc surfaces are provided at one end of the clamping block extending into the installation groove, and the two arc surfaces are symmetrically distributed in an "eight" shape.

[0010] Preferably, a notch is provided at the other end of the clamping block. The notch is a "匸" - shaped groove, and an elastic band is fixed on the surface of the notch. The two ends of the elastic band are respectively fixed on two parallel side walls of the jack. When the turntable squeezes and pushes the clamping block to clamp the precast concrete wall, the clamping block tenses the elastic band to produce elastic deformation.

[0011] Preferably, the turntable is an annular plate. A limiting shaft is fixed on the surface of the installation groove. The limiting shaft is a "T" - shaped round rod. The rod body of the limiting shaft penetrates through the inner ring opening of the turntable and is fixed on the surface of the installation groove. The notch and the clamping block correspond one by one, and a rubber block is fixed on the side wall of the installation groove. The rubber block is inserted into the notch.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The splicing structure of the precast concrete component proposed by the present utility model realizes the rapid and accurate docking between precast concrete walls through the design of structures such as the splicing frame and the wing plate. During splicing, only need to install the splicing frame between two adjacent precast concrete walls and ensure the correct docking of the limiting frame and the clamping groove, the wing plate and the assembling groove, which greatly simplifies the splicing process and improves the construction efficiency. Through the design of structures such as the turntable and the clamping block, the detachable connection between the splicing frame and the precast concrete wall is realized. When it is necessary to拆除 (should be "dismantle" in English) or replace, only need to turn the turntable to make the clamping block loosen the precast concrete wall, without damaging the overall structure, which is convenient for disassembly and reuse.

[0025] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figures 1 to 10 This utility model provides a technical solution: a prefabricated concrete component splicing structure, including a splicing frame 1 installed between two prefabricated concrete walls 2. Both ends of the splicing frame 1 are integrally formed with wing plates 3, and the two ends of the wing plates 3 are respectively inserted into the surfaces of the two prefabricated concrete walls 2. The splicing frame 1 has a square frame structure. The groove of the splicing frame 1 is used for pouring concrete. The width of the wing plates 3 is greater than the width of the splicing frame 1. Both sides of the splicing frame 1 are integrally formed with limit frames 5. The limit frames 5 are square frames and are inserted into the inside of the slots 6. The slots 6 are opened at the ends of the prefabricated concrete walls 2. Both sides of the prefabricated concrete walls 2 are provided with assembly grooves 4, and the ends of the wing plates 3 are inserted into the assembly grooves 4.

[0027] During use, after the precast concrete wall 2 is transported to the construction site, the splicing frame 1 is installed between two adjacent precast concrete walls 2. In order to prevent the two precast concrete walls 2 from being assembled obliquely, limit frames 5 are provided on both sides of the splicing frame 1. The limit frames 5 are inserted into the card slots 6 provided at the ends of the precast concrete walls 2, and the ends of the wing plates 3 are inserted into the assembly slots 4. In order to enhance the strength of the splicing frame 1, after the splicing frame 1 is fixed between two adjacent precast concrete walls 2, concrete is poured from the top slot of the splicing frame 1, and the slot of the splicing frame 1 is filled with concrete.

[0028] Installation grooves 7 are provided at both ends of the wing plate 3. Clamping blocks 9 are inserted on the surface of the installation grooves 7. The installation grooves 7 are circular grooves. There are four installation grooves 7, and the four installation grooves 7 are respectively distributed at the four corners of the wing plate 3. Two jacks 8 are provided on the surface of the installation grooves 7. The clamping blocks 9 and the jacks 8 correspond one by one, and the clamping blocks 9 are movably inserted into the jacks 8. Two arc surfaces are provided at one end of the clamping block 9 extending into the installation groove 7. The two arc surfaces are symmetrically distributed in an "eight" shape. A turntable 12 is rotatably connected inside the installation groove 7. A notch 14 is provided on the surface of the turntable 12. After the notch 14 and the clamping block 9 are misaligned, the turntable 12 squeezes the clamping block 9 to clamp the precast concrete wall 2. A notch 10 is provided at the other end of the clamping block 9. The notch 10 is a "匸" - shaped groove. An elastic band 11 is fixed on the surface of the notch 10. Two ends of the elastic band 11 are respectively fixed on two parallel side walls of the jack 8. When the turntable 12 squeezes and pushes the clamping block 9 to clamp the precast concrete wall 2, the clamping block 9 stretches the elastic band 11 to generate elastic deformation; the turntable 12 is an annular plate. A limit shaft 13 is fixed on the surface of the installation groove 7. The limit shaft 13 is a "T" - shaped round rod. The rod body of the limit shaft 13 passes through the inner ring opening of the turntable 12 and is fixed on the surface of the installation groove 7. The notch 14 and the clamping block 9 correspond one by one. A rubber block 15 is fixed on the side wall of the installation groove 7. The rubber block 15 is inserted into the notch 14.

[0029] During use, in order to fix the splicing frame 1 on the precast concrete wall 2, when the end of the wing plate 3 extends into the assembly slot 4, two fingers are inserted into the two notches 14 to拨动 the turntable 12 to rotate around the limit shaft 13 as the central axis until the notch 14 and the clamping block 9 are misaligned. At this time, the clamping block 9 is squeezed by the turntable 12, the clamping block 9 is pressed against one side of the precast concrete wall 2, and the elastic band 11 is stretched and deformed by the clamping block 9. And at this time, the rubber block 15 is inserted into the notch 14 to prevent the turntable 12 from rotating randomly in the installation groove 7. At this time, the splicing frame 1 is fixed at one end of the precast concrete wall 2; when it is necessary to cancel the clamping of the precast concrete wall 2 by the clamping block 9, the turntable 12 is rotated again around the limit shaft 13 as the central axis until the notch 14 and the clamping block 9 are opposite. At this time, the elastic band 11 rebounds to drive the clamping block 9 to slide back to its original position along the jack 8, and the clamping block 9 no longer clamps the precast concrete wall 2.

[0030] The detailed usage process of this precast concrete component splicing structure is summarized below.

[0031] Installation steps: Transport the precast concrete wall 2 to the construction site. Install the splicing frame 1 between two adjacent precast concrete walls 2, ensuring that the limiting frame 5 is inserted into the slot 6 and the end of the wing plate 3 is inserted into the assembly slot 4.

[0032] To enhance the strength of the splicing frame: After the splicing frame 1 is fixed between two adjacent precast concrete walls 2, concrete is poured from the top groove of the splicing frame 1 until the groove of the splicing frame 1 is filled, so as to enhance the strength and stability of the overall structure.

[0033] Wing plate fixing mechanism: A clamping block and turntable structure is used. Mounting grooves 7 are formed at both ends of the wing plate 3, and a turntable 12 is rotatably connected within the mounting grooves 7. A notch 14 is formed on the surface of the turntable 12. Insertion holes 8 are formed on the surface of the mounting grooves 7, and clamping blocks 9 are movably inserted into the insertion holes 8. One end of the clamping block 9 has two symmetrically distributed arc surfaces in a figure-eight shape for clamping the precast concrete wall 2. A notch 10 is formed at the other end of the clamping block 9, and an elastic band 11 is fixed to the surface of the notch 10. The two ends of the elastic band 11 are respectively fixed to two parallel sidewalls of the insertion hole 8.

[0034] Working principle of the clamping block: When the end of the wing plate 3 extends into the assembly groove 4, the turntable 12 rotates around the limiting shaft 13 via the notch 14. When the notch 14 and the clamping block 9 are misaligned, the turntable 12 squeezes the clamping block 9, causing it to clamp the precast concrete wall 2, while the elastic band 11 is stretched and undergoes elastic deformation. The rubber block 15 is inserted into the notch 14 to prevent the turntable 12 from rotating freely in the installation groove 7, thereby fixing the splicing frame 1 on the precast concrete wall 2.

[0035] Unclamping: When it is necessary to unclamp the precast concrete wall 2 with clamping block 9, turntable 12 is rotated again around the limiting shaft 13 until the notch 14 and clamping block 9 are aligned. At this time, the elastic band 11 rebounds and causes clamping block 9 to slide back along the insertion hole 8, and clamping block 9 no longer clamps the precast concrete wall 2.

[0036] Overall workflow:

[0037] Preparation stage: Transport the precast concrete wall 2 to the construction site and prepare the splicing frame 1 and other necessary materials.

[0038] Install the splicing frame: Install the splicing frame 1 between two adjacent precast concrete walls 2, ensuring that the limiting frame 5 and the slot 6, the wing plate 3 and the assembly slot 4 are correctly aligned.

[0039] Concrete pouring: Concrete is poured from the top slot of splicing frame 1 to improve the strength and stability of the overall structure.

[0040] Fixed wing plate: The splicing frame 1 is fixed to the precast concrete wall 2 by the interaction of the turntable 12 and the clamping block 9.

[0041] Unclamp (if needed): When necessary, unclamp the precast concrete wall 2 by turning the dial 12.
