Technical Field

[0001] The utility model relates to a fixed connection device, in particular to a fixed connection device for prefabricated components, and belongs to the technical field of construction engineering. Background Art

[0002] Prefabricated crash barriers are a special type of concrete panel wall prefabricated in a factory. They have anti-collision and fire-proof functions and are widely used in places that require anti-collision, such as highway guardrails, parking lots, and docks. When in use, multiple prefabricated crash barriers need to be spliced into a whole at the construction site. The specific operation is to install the prefabricated crash barriers one by one into the pit, and then splice the two adjacent prefabricated crash barriers by bolt connection or mortise and tenon structure splicing. During the splicing process, it is necessary to ensure that the prefabricated blocks are tightly overlapped and no gaps exist.

[0003] However, traditional prefabricated crash barriers use a mortise and tenon structure splicing method, in which a trapezoidal protrusion with the same height as the prefabricated crash barrier is set on one side of one of the prefabricated crash barriers. During installation, it is necessary to completely lift up one of the prefabricated crash barriers so that the protrusion on the prefabricated crash barrier is aligned with the slot of the other prefabricated crash barrier, and then place the prefabricated crash barrier from the top of the other prefabricated crash barrier. The operation is relatively laborious and not flexible enough, resulting in time-consuming and labor-intensive installation. Utility Model Content

[0004] The purpose of the present utility model is to provide a fixed connection device for prefabricated components in order to solve the above problems. By engaging the protrusions on the prefabricated crash barrier with the slots on the adjacent prefabricated crash barrier, the two adjacent prefabricated crash barrier walls can be quickly spliced into a whole, making the installation more time-saving and labor-saving, and making the installation of the prefabricated crash barrier more convenient.

[0006] Preferably, the protrusion is a trapezoidal structure, and the slot is a trapezoidal structure.

[0007] Preferably, the grooves and the card slots are spaced apart, and the grooves and the adjacent card slots together form an "L"-shaped structure.

[0008] Preferably, the cross-section of the prefabricated crash barrier is in a "T"-shaped structure, a sealing block is engaged in the groove, and the volume of the sealing block at the bottom end of the prefabricated crash barrier is larger than the other two sealing blocks.

[0009] Preferably, three fixing sleeves are fixedly connected inside the prefabricated anti-collision wall, and the same fixing rod is slidably connected inside the three fixing sleeves, and the fixing rod is slidably connected to the sealing block.

[0010] Preferably, a connecting plate is fixedly connected to the top end of the fixing rod, and the connecting plate is fixedly connected to the top end of the adjacent prefabricated crash barrier via expansion bolts.

[0011] Preferably, three positioning holes are opened on the top of the prefabricated anti-collision wall, and the three positioning holes are distributed in a linear array.

[0012] Preferably, rubber pads are installed on both sides of the prefabricated crash barrier, and the rubber pads on two adjacent prefabricated crash barrier contacts each other.

[0013] The beneficial effects of the present invention are as follows: four protrusions are fixedly connected to one side of the prefabricated anti-collision wall, and four slots are provided on the other side of the prefabricated anti-collision wall. The protrusions on the prefabricated anti-collision wall are engaged with the corresponding slots on the adjacent prefabricated anti-collision wall, and three grooves are provided on the side of the prefabricated anti-collision wall facing the slots, and the grooves are connected with the adjacent slots; by engaging the protrusions on the prefabricated anti-collision wall with the slots on the adjacent prefabricated anti-collision wall, the two adjacent prefabricated anti-collision walls can be quickly spliced into a whole, and at the same time, the prefabricated anti-collision wall is provided with grooves that are connected with the corresponding slots and are perpendicular to each other.

The grooves 4 and the card slots 3 are spaced apart, and the grooves 4 and the adjacent card slots 3 together form an "L"-shaped structure.

[0021] As a technical optimization solution of the present invention, the protrusion 2 is in a trapezoidal structure, and the slot 3 is in a trapezoidal structure; the protrusion 2 slides out of the slot 3, which increases the stability of the connection between the protrusion 2 and the slot 3.

[0022] As a technical optimization solution of the present invention, the cross-section of the prefabricated crash barrier 1 is a "T"-shaped structure, and a sealing block 5 is engaged in the groove 4. The volume of the sealing block 5 at the bottom end of the prefabricated crash barrier 1 is larger than that of the other two sealing blocks 5; the three sealing blocks 5 are engaged in the corresponding grooves 4 in sequence to prevent moisture and debris from entering the gap and affecting the service life of the prefabricated crash barrier 1, and the outside of the sealing block 5 is bonded with reflective paint, which can act as a warning strip and provide a good warning effect for passing vehicles.

[0023] As a technical optimization solution of the present invention, three fixing sleeves 6 are fixedly connected in the prefabricated anti-collision wall 1, and the same fixing rod 7 is slidably connected in the three fixing sleeves 6. The fixing rod 7 is slidably connected to the sealing block 5, and the top of the fixing rod 7 is fixedly connected to a connecting plate 8, and the connecting plate 8 is fixedly connected to the top of the adjacent prefabricated anti-collision wall 1 through an expansion bolt; the fixing rod 7 is slid downward from the top of the prefabricated anti-collision wall 1 on which the fixing sleeve 6 is installed, so that the fixing rod 7 passes through the fixing sleeve 6 and the sealing block 5, so that the sealing block 5 is fixed and cannot slip off the prefabricated anti-collision wall 1, thereby increasing the stability of the installation of the sealing block 5, and the fixing sleeve 6 can reduce the friction between the fixing rod 7 and the inner wall of the prefabricated anti-collision wall 1, thereby reducing the wear on the prefabricated anti-collision wall 1; then the connecting plate 8 at the top of the fixing rod 7 is fixed to the other prefabricated anti-collision wall 1 through the expansion bolt, so that the fixing rod 7 is fixed, and at the same time, the other prefabricated anti-collision wall 1 cannot drive the protrusion 2 to slide upward, thereby increasing the stability of the splicing of the two prefabricated anti-collision walls 1.

[0024] As a technical optimization solution of the present invention, three positioning holes 9 are opened at the top of the prefabricated anti-collision wall 1, and the three positioning holes 9 are distributed in a linear array; the positioning holes 9 opened at the top of the prefabricated anti-collision wall 1 facilitate the positioning of the installation columns of the partition wall when the partition wall is installed at the top of the prefabricated anti-collision wall 1.

[0025] As a technical optimization solution of the present invention, rubber pads 10 are installed on both sides of the prefabricated crash barrier 1, and the rubber pads 10 on the two adjacent prefabricated crash barrier walls 1 conflict with each other; when the two prefabricated crash barrier walls 1 are spliced, the rubber pads 10 on the two prefabricated crash barrier walls 1 conflict with each other, which can enhance the stability of the splicing point and improve the seismic performance of the prefabricated crash barrier 1.

When the protrusion 2 conflicts with the inner wall of the prefabricated anti-collision wall 1, the other prefabricated anti-collision wall 1 is released, and the prefabricated anti-collision wall 1 drives the protrusion 2 to slide downward, so that the protrusion 2 and the card The slots 3 are engaged. Since the slots 3 and the protrusions 2 are both trapezoidal structures, when the protrusions 2 are engaged with the slots 3, the protrusions 2 can no longer move in the horizontal direction, thereby quickly splicing the two prefabricated crash barriers 1. The operation is flexible and convenient, saving time and effort, and making the installation more efficient. Then, the three sealing blocks 5 are sequentially engaged with the corresponding grooves 4 to prevent moisture and debris from entering the gaps and affecting the service life of the prefabricated crash barrier 1.

Then, slide the fixing rod 7 downward from the top of the prefabricated anti-collision wall 1 installed with the fixing sleeve 6, so that the fixing rod 7 passes through the fixing sleeve 6 and the sealing block 5, so that the sealing block 5 is fixed and cannot slip off the prefabricated anti-collision wall 1, thereby increasing the stability of the installation of the sealing block 5, and the fixing sleeve 6 can reduce the friction between the fixing rod 7 and the inner wall of the prefabricated anti-collision wall 1, thereby reducing the wear of the prefabricated anti-collision wall 1; then fix the connecting plate 8 at the top of the fixing rod 7 to the other prefabricated anti-collision wall 1 through the expansion bolt, so that the fixing rod 7 is fixed, and at the same time, the other Each prefabricated anti-collision wall 1 cannot drive the protrusion 2 to slide upward, thereby increasing the stability of the splicing of the two prefabricated anti-collision walls 1; the positioning hole 9 opened at the top of the prefabricated anti-collision wall 1 facilitates the positioning of the installation column of the partition wall when installing the partition wall on the top of the prefabricated anti-collision wall 1; when the two prefabricated anti-collision walls 1 are completed, the rubber pads 10 on the two prefabricated anti-collision walls 1 conflict with each other, which can enhance the stability of the splicing and improve the seismic performance of the prefabricated anti-collision wall 1. At the same time, it can also prevent moisture and debris from entering the gap and affecting the service life of the anti-collision wall.
