Description

Technical Field

[0001] This invention relates to the field of prefabricated building component construction technology, specifically a prefabricated building component connection device. Background Technology

[0002] To promote efficient construction and green development, infrastructure and building construction are trending towards standardized design, factory production, and assembly-based construction. Precast components are increasingly used in engineering construction. After production, these components need to be transported to their installation locations using transportation equipment. During transportation, the components may experience bumps and vibrations, causing deformation of the elastic components and resulting in vertical fluctuations that can affect their shape and potentially lead to deformation. Therefore, they need to be secured.

[0003] Because the existing connection mechanism is installed on the screws reserved on the prefabricated components, the screws have low strength. During transportation, the screws may deform or break, causing the prefabricated components to shift, which greatly reduces the practicality of the equipment.

[0004] Therefore, it is necessary to design a precast component connection device that is practical, avoids damage to precast components, and is applicable to different types of precast components. Summary of the Invention

[0005] The purpose of this invention is to provide a connection device for prefabricated building components to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a precast building component connection device, comprising a precast component, wherein a plurality of reserved holes are provided on all four sides of the precast component, and mounting plates are provided on all four sides of the precast component. Two sets of mounting holes are provided on the upper and lower sides of the mounting plates, and fastening threaded holes are provided at the four corners of the mounting plates. The fastening threaded holes communicate with the mounting holes and fastening bolts are screwed into the fastening threaded holes. A connecting rod is provided in the mounting hole and the connecting rod is slidably connected to the mounting hole.

[0007] According to the above technical solution, the mounting plate is provided with slots on both the left and right sides, and two locking blocks are provided in the slots. The locking blocks are slidably connected to the slots. A screw rod is fixedly connected to one side of the locking block, and a connecting rod is fixedly connected between the screw rods. A screw nut is screwed to the other side of the screw rod.

[0008] According to the above technical solution, the mounting plate is provided with a plurality of threaded holes, the threaded holes are connected to the reserved holes, and bolts are provided in the threaded holes, with the bolts partially penetrating the threaded holes and inserted into the reserved holes.

[0009] According to the above technical solution, a knob is fixedly connected to one side of the mounting plate on the bolt, an expansion sleeve is provided on the bolt, the expansion sleeve wraps around the bolt, an external thread is provided on the outer side of the expansion sleeve, the external thread is screwed into the threaded hole, an expansion head is provided on one side of the expansion sleeve, and the expansion head is screwed into the bolt.

[0010] According to the above technical solution, the length of the lead screw nut is greater than twice the thread length of the lead screw.

[0011] According to the above technical solution, the total length of the two sets of lead screws and lead screw nuts is much smaller than the distance between the two reserved holes.

[0012] According to the above technical solution, a method of using a prefabricated building component connection device is as follows:

[0013] S1: Attach the mounting plate to one side surface of the precast component, so that the threaded holes on the mounting plate coincide with the reserved holes;

[0014] S2: Rotate the knob to screw the bolt into the pre-drilled hole, but do not tighten it, so that the mounting plate can move around the bolt;

[0015] S3: Install another mounting plate on the reserved part surface on the same side as the mounting plate above, following the steps described above.

[0016] S4: Install the two sets of cards into the slots on the adjacent sides of the two mounting plates respectively;

[0017] S5: At the same time, install the lead screw nut on the lead screw of the two sets of fixing blocks, and adjust the lead screw nut to make the two mounting plates be aligned vertically and keep them compact in the horizontal direction;

[0018] S6: Then tighten the knob to completely fix the mounting plate to the precast component;

[0019] S7: Similarly, follow the above steps to connect the remaining sides of the prefabricated components.

[0020] S8: When the second precast component is on the same side as the first precast component, the above steps can be followed to connect and fix the two precast components to prevent displacement.

[0021] S9: When the second precast component is placed on the first precast component, the mounting plate is now fixed on the surface of the precast component according to the above steps SS.

[0022] S10: Then, connect the connecting rod to the mounting holes of the upper and lower mounting plates;

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, please refer to Figure 1-5The present invention provides a technical solution: a prefabricated building component connection device, including a prefabricated component 1, a plurality of reserved holes 2 are opened on all four sides of the prefabricated component 1, an mounting plate 3 is provided on all four sides of the prefabricated component 1, a plurality of threaded holes 4 are opened on the mounting plate 3, the threaded holes 4 communicate with the reserved holes 2, a bolt 5 is provided in the threaded hole 4, the bolt 5 partially penetrates the threaded hole 4 and is inserted into the reserved hole 2, a knob 6 is fixedly connected to one side of the mounting plate 3 on the bolt 5, an expansion sleeve 7 is provided on the bolt 5, the expansion sleeve 7 wraps around the bolt 5, an external thread 8 is opened on the outer side of the expansion sleeve 7, the external thread 8 is screwed into the threaded hole 4, an expansion head 9 is provided on one side of the expansion sleeve 7, and the expansion head 9 is screwed into the bolt 5;

[0035] In this embodiment, by rotating the knob 6 fixed to one side of the bolt 5, the knob 6 drives the bolt 5 to tighten into the pre-drilled hole 2. Under the influence of the diameter of the pre-drilled hole 2, the expansion head 9 is stuck at a certain point and fixed, while the bolt 5 continues to tighten inward with the expansion sleeve 7. When the inward side of the expansion sleeve 7 touches the expansion head 9, the expansion head 9 exerts pressure on one side of the expansion sleeve 7 due to the fixed expansion head 9. Under the influence of the pressure, the expansion sleeve 7 will expand outward, thereby filling the pre-drilled hole 2 and fixing the bolt 5 in the pre-drilled hole 2, thereby fixing the mounting plate 3 to the prefabricated component 1. When it is necessary to remove the mounting plate 3, rotate the knob 6 in the opposite direction to disengage the expansion head 9 from the expansion sleeve 7, pull the bolt 5 outward, and the expansion sleeve 7 and expansion head 9 can be pulled out of the pre-drilled hole 2. The above components will not cause damage to the prefabricated component 1 during installation and disassembly.

[0036] Example 2, based on Example 1, adds the following structure:

[0037] The mounting plate 3 has slots 10 on both the left and right sides, and two blocks 11 are provided in the slots 10. The blocks 11 are slidably connected to the slots 10. A screw rod 12 is fixedly connected to one side of the blocks 11. A connecting rod 13 is fixedly connected between the screw rods 12. A screw nut 14 is screwed to the other side of the screw rod 12. The mounting plate 3 has two sets of mounting holes 15 on both the top and bottom sides. The mounting plate 3 has fastening threaded holes 16 at each of the four corners. The fastening threaded holes 16 communicate with the mounting holes 15. Fastening bolts 17 are screwed into the fastening threaded holes 16. A connecting rod 18 is provided in the mounting holes 15. The connecting rod 18 is slidably connected to the mounting holes 15.

[0038] Specifically, the length of the lead screw nut 14 is greater than twice the thread length of the lead screw 12, ensuring that the length between the lead screws can be effectively adjusted;

[0039] Specifically, the total length of the two sets of lead screws 12 and lead screw nuts 14 is much smaller than the distance between the two reserved holes 2, and ensures that the two sets of mounting plates can be connected;

[0040] In this embodiment, two mounting plates 3 are symmetrically installed on one side of each precast component 1. On the adjacent side between the two mounting plates 3, a locking block 11 with a lead screw 12 is installed into the locking slot 10. On the side of the two sets of lead screws 12 away from the locking block 11, a lead screw nut 14 is screwed on, so that the lead screw nut 14 connects the two lead screws 12 together. The distance between the bolts 5 on the two mounting plates 3 can be adjusted by the length of the lead screw 12 screwed on by the lead screw nut 14, so that the mounting plates 3 can be installed between different types of reserved holes 2. When the bolt 5 is outside the reserved hole 2, stop turning the lead screw nut 14, and then tighten the knob 6 to fix the mounting plate 3 on the precast component 1. The other three sides of the precast component 1 are installed through the above steps. When the second precast component 1 is placed on one side of the first precast component 1, it can be connected by the lead screw 12 and the lead screw nut 14 to fix the two precast components 1 to each other and prevent displacement.

[0041] Similarly, when the second precast component 1 is placed on top of the first precast component 1, the two mounting plates 3 are installed on the precast component 1 again through the above steps. At this time, the mounting connecting rod 18 is installed in the corresponding mounting holes 15 of the upper and lower mounting plates 3. The mounting plates 3 can reciprocate on the connecting rod 18 through the mounting holes 15, which is convenient for adjusting the distance between the upper and lower mounting plates 3. When the bolt 5 is outside the reserved hole 2, tighten the fastening bolt 17 so that the fastening bolt 17 abuts against the connecting rod 18 to fix the connecting rod 18 and prevent the upper and lower mounting plates 3 from shifting. This allows the equipment to be installed on multiple precast components 1 of different models. When the third or more precast components 1 are superimposed on the second precast component 1, the above steps are repeated to connect the multiple precast components 1.

[0042] A method for using a connection device for prefabricated building components:

[0043] S1: Attach the mounting plate 3 to one side surface of the precast component 1, so that the threaded hole 4 on the mounting plate 3 coincides with the reserved hole 2;

[0044] S2: Rotate knob 6 to screw bolt 5 into the pre-drilled hole 2, but do not tighten it, so that mounting plate 3 can move around bolt 5;

[0045] S3: Install another mounting plate 3 on the surface of the reserved part 1 on the same side as the mounting plate 3 above, following the steps described above.

[0046] S4: Install the two sets of card blocks 11 into the card slots 10 on the adjacent sides of the two mounting plates 3 respectively;

[0047] S5: At the same time, install the lead screw nut 14 on the lead screw 12 on the two sets of fixing blocks 11, and adjust the lead screw nut 14 so that the two mounting plates 3 are in the same vertical position and are kept compact in the horizontal direction;

[0048] S6: Then tighten knob 6 to completely fix mounting plate 3 onto prefabricated component 1;

[0049] S7: Similarly, the other sides of the precast component 1 are operated according to the above steps;

[0050] S8: When the second precast component 1 is on the same side as the first precast component 1, the above steps can be followed to connect and fix the two precast components 1 to avoid displacement.

[0051] S9: When the second precast component 1 is placed on the first precast component 1, the mounting plate 3 is now fixed on the surface of the precast component 1 according to the above steps S1-S6.

[0052] S10: Then, connect the connecting rod 18 to the mounting holes 15 of the upper and lower sets of mounting plates 3;

[0053] S11: Then tighten the fastening bolt 17 so that the fastening bolt 17 abuts against the connecting rod 18, so that the connecting rod 18 is fixed and the upper and lower sets of mounting plates 3 are fixedly connected.

[0054] S12: The above operation can fix the position of the upper and lower prefabricated components 1 to prevent displacement.
