Description

Technical Field

[0001] This invention relates to the field of building component technology, and in particular to a device and method for rapid positioning and connection of prefabricated building components. Background Technology

[0002] Prefabricated building components refer to standardized building parts, such as wall panels, prefabricated beams, and prefabricated columns, which are manufactured in factories and need to be positioned and connected on the construction site. Currently, in prefabricated buildings, the vertical connection between beams and columns is usually achieved using steel components, threaded connectors, and other structural components.

[0003] Currently, steel components are typically secured to beams and columns using multiple threaded connectors. These multiple threaded connectors must be installed one by one, requiring strict precision in hole positioning. Even slight misalignment necessitates readjustment or even hole enlargement, increasing construction time and labor costs. This makes it difficult to meet the demands for rapid positioning and connection. Furthermore, threaded connections are susceptible to vibration, temperature changes, and other factors, leading to the risk of loosening or breakage. Regular maintenance and inspection are required to maintain their tightness, resulting in high maintenance costs. Summary of the Invention

[0004] Therefore, it is necessary to provide a rapid positioning and connection installation device and method for prefabricated building components, addressing the issues of low connection speed and heavy subsequent maintenance burden in the positioning and connection installation devices for prefabricated building components.

[0005] A rapid positioning and connection installation device for prefabricated building components includes steel components, vertical embedded parts, and horizontal embedded parts. The steel components, vertical embedded parts, and horizontal embedded parts are all provided with interconnected through holes at their opposite ends. Threaded connectors that insert into the through holes are installed on both the vertical and horizontal embedded parts.

[0006] Furthermore, the threaded connector installed on the vertical embedded part includes a bolt, a nut, and a round block. The bolt and nut are respectively located on opposite sides of the vertical embedded part and the steel component. The shank of the bolt passes through the adjacent through hole and is threadedly connected to the nut. The round block is fixedly connected to the axis of the shank of the bolt. The side end of the round block has a unidirectional positioning groove distributed in a ring. An adjustable protective component is installed on the surface of the round block at the end of the nut facing away from the bolt head. The inner side of the adjustable protective component is slidably connected to a unidirectional positioning block that engages with the adjacent unidirectional positioning groove.

[0007] Furthermore, the horizontal cross-sectional shape of the unidirectional positioning groove and the unidirectional positioning block engaging with the unidirectional positioning groove is a right-angled triangle, and the direction in which the unidirectional positioning groove blocks the movement of the unidirectional positioning block is the same as the direction in which the nut moves away from the bolt head.

[0008] Furthermore, the nut has a regular hexagonal sliding cavity at the end facing away from the bolt head. The adjustable protective assembly includes a regular hexagonal sleeve slidably connected inside the regular hexagonal sliding cavity. The bolt, which passes through the nut, is partially disposed inside the regular hexagonal sleeve. The regular hexagonal sleeve has a circular groove on its inner wall facing the nut to accommodate a circular block. The regular hexagonal sleeve has a guide cavity communicating with the circular groove inside. The one-way positioning block is slidably connected inside the guide cavity. A rubber spring, which is fixedly connected to the nut, is fixedly connected to the outer side of the regular hexagonal sleeve. The rubber spring is always in a stretched state.

[0009] Furthermore, the vertical cross-sectional shape of the contact area between the guide cavity and the unidirectional positioning block is a matching rectangle.

[0010] Furthermore, the rubber spring is shaped like a hollow regular hexagonal truncated pyramid, and the connection between the regular hexagonal sheath and the regular hexagonal sliding cavity is located on the inner side of the rubber spring.

[0011] Furthermore, a regular hexagonal positioning frame is slidably connected inside the regular hexagonal cavity. The end of the regular hexagonal positioning frame facing away from the bolt head is fixedly connected to the regular hexagonal sheath. The horizontal width of the regular hexagonal positioning frame is greater than the horizontal inner diameter of the opening of the regular hexagonal cavity.

[0012] Furthermore, the corner of the round block facing away from the nut is beveled to connect with the one-way positioning groove, and the horizontal cross-sectional length of the bevel is greater than the horizontal depth of the one-way positioning groove.

[0013] Furthermore, the number of guide cavities and unidirectional positioning blocks is the same and there are no fewer than two of each, and the guide cavities and unidirectional positioning blocks are distributed in a ring around the axis of the circular block.

[0014] Furthermore, a metal spring is provided between the guide cavity and the one-way positioning block, and the metal spring is in a compressed state.

[0015] An installation method for a rapid positioning and connection installation device for prefabricated building components, the specific installation method is as follows:

[0016] I. Installation of Embedded Parts:

[0017] Vertical and horizontal embedded parts are respectively embedded and cast into the ends of precast columns and precast beams;

[0018] II. Positioning and Installation of Steel Components:

[0019] a: Hoist the steel component to the top of the vertical embedded part, ensuring that the perforation on the steel component is aligned with the perforation on the vertical embedded part;

[0020] b: Pass the bolts through the aligned holes to complete the vertical positioning of the steel component and the vertical embedded parts;

[0021] c: Screw the nut into the bolt shank until both are tightly against the steel component and the vertical embedded part, respectively;

[0022] III. Horizontal positioning and installation of precast beams:

[0023] a: Hoist the precast beam and move the end with the horizontal embedded part to the side of the steel component;

[0024] b: Adjust the position of the precast beam so that the perforations on the steel components are aligned with the perforations of the horizontal embedded parts;

[0025] c: Pass the bolts through the aligned holes to complete the horizontal positioning of the steel component and the horizontal embedded part;

[0026] d: Screw the nut into the bolt shank until both are tightly against the steel component and the horizontal embedded part, respectively.

[0027] The above-mentioned prefabricated building component quick positioning and connection installation device and installation method, the threaded connector can lock the bolt and nut together in one direction without changing the existing function of quick positioning and connection installation of bolts and nuts. This can prevent the bolt or nut from loosening. It can not only ensure that the precast beam and precast column can be stably connected together, but also reduce the frequency of maintenance of the threaded connector by the staff.

[0028] The adjustable protective component not only enables the one-way positioning block and one-way positioning groove to be effectively engaged, allowing the self-locking function to function properly, but also seals the connection between the nut and bolt. This effectively prevents external dust, moisture, and other impurities from corroding the connection between the nut and bolt, significantly reducing the likelihood of structural changes in the nut and bolt themselves. This further ensures the stable connection between the precast beam and the precast column. Furthermore, because the adjustable protective component is telescopic, it can be used with bolts of different lengths, thus expanding the overall applicability of this threaded connector.

[0045] The following is combined Figures 1-8 This invention describes a device and method for rapid positioning and connection of prefabricated building components.

[0046] In one embodiment, a rapid positioning and connection installation device for prefabricated building components includes a steel component 100, a vertical embedded part 200, and a horizontal embedded part 300. Each of the steel component 100, the vertical embedded part 200, and the horizontal embedded part 300 has a through hole 400 at its opposite end. Each of the vertical embedded part 200 and the horizontal embedded part 300 is equipped with a threaded connector 500 that plugs into the through hole 400. The shape and material of the steel component 100, the vertical embedded part 200, and the horizontal embedded part 300 need to be customized according to the size of the precast beams and columns, the installation space, and the scene. Furthermore, the location of the through hole 400 needs to be such that it does not affect the structural strength of the steel component 100, the vertical embedded part 200, and the horizontal embedded part 300 themselves.

[0047] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the threaded connector 500 installed on the vertical embedded part 200 includes a bolt 510, a nut 520, and a round block 530. The bolt 510 and nut 520 are respectively located on opposite sides of the vertical embedded part 200 and the steel component 100. The shank of the bolt 510 passes through an adjacent through hole 400 and is threadedly connected to the nut 520. The round block 530 is fixedly connected to the axis of the shank of the bolt 510. A one-way positioning groove 531 distributed in a ring is opened on the side end of the round block 530. An adjustable protective component is installed on the surface of the round block 530 at the end of the nut 520 facing away from the head of the bolt 510. 540, the adjustable protective component 540 has a slidably connected unidirectional positioning block 550 that engages with the adjacent unidirectional positioning groove 531; the horizontal cross-sectional shape of the unidirectional positioning groove 531 and the unidirectional positioning block 550 engaging with the unidirectional positioning groove 531 is a right triangle, and the direction in which the unidirectional positioning groove 531 blocks the movement of the unidirectional positioning block 550 is the same as the direction in which the nut 520 moves away from the head of the bolt 510; the corner of the round block 530 facing away from the nut 520 has a chamfer that connects with the unidirectional positioning groove 531, and the horizontal cross-sectional length of the chamfer is greater than the horizontal depth of the unidirectional positioning groove 531.

[0048] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a regular hexagonal cavity 521 is provided at the end of the nut 520 facing away from the head of the bolt 510. The adjustable protective assembly 540 includes a regular hexagonal sleeve 541 slidably connected inside the regular hexagonal cavity 521. The bolt 510 is partially disposed inside the regular hexagonal sleeve 541, passing through the nut 520. A circular groove 542 for accommodating a circular block 530 is provided on the inner wall of the regular hexagonal sleeve 541 facing the nut 520. A guide cavity 543 communicating with the circular groove 542 is provided inside the regular hexagonal sleeve 541. The one-way positioning block 550 is slidably connected... Inside the guide cavity 543, a rubber spring 544, which is fixedly connected to the nut 520, is fixedly connected to the outer side of the regular hexagonal sleeve 541. The rubber spring 544 is always in a stretched state. The vertical cross-sectional shape of the contact area between the guide cavity 543 and the one-way positioning block 550 is a matching rectangle. The rubber spring 544 is a hollow regular hexagonal frustum. The connection between the regular hexagonal sleeve 541 and the regular hexagonal sliding cavity 521 is located on the inner side of the rubber spring 544, which can effectively seal the connection between the regular hexagonal sleeve 541 and the regular hexagonal sliding cavity 521. At the joint, to reduce the adhesion of external dust and other impurities at the connection between the hexagonal sheath 541 and the hexagonal sliding cavity 521, thereby ensuring the normal expansion and contraction of the hexagonal sheath 541; a hexagonal positioning frame 545 is slidably connected inside the hexagonal sliding cavity 521, one end of the hexagonal positioning frame 545 facing away from the head of the bolt 510 is fixedly connected to the hexagonal sheath 541, and the horizontal width of the hexagonal positioning frame 545 is greater than the horizontal inner diameter of the opening of the hexagonal sliding cavity 521, which can limit the movement range of the hexagonal sheath 541 to avoid The hexagonal sheath 541 is detached from the hexagonal sliding cavity 521; the number of guide cavities 543 and one-way positioning blocks 550 is the same and there are no fewer than two of each. The guide cavities 543 and one-way positioning blocks 550 are arranged in a ring around the axis of the circular block 530; a metal spring 560 is provided between the guide cavity 543 and the one-way positioning block 550. The metal spring 560 is in a compressed state. The metal spring 560 can automatically reset the one-way positioning block 550 after it loses its obstruction, so as to ensure that the one-way positioning block 550 can play a normal anti-return role.

[0049] During the process of screwing the nut 520 onto the surface of the bolt 510, the nut 520 drives the regular hexagonal sleeve 541 to approach the round block 530 through the regular hexagonal sliding cavity 521. When the round block 530 enters the interior of the round groove 542 and presses against the round groove 542, the regular hexagonal sleeve 541 cannot follow the nut 520 to approach the head of the bolt 510. At the same time, the nut 520 can still drive the regular hexagonal sleeve 541 to rotate through the regular hexagonal sliding cavity 521, so that the regular hexagonal sleeve 541 drives the one-way positioning block 550 to rotate and engage or disengage from the one-way positioning groove 531 it passes through through the guide cavity 543.

[0050] like Figure 3, Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a transparent window communicating with a circular groove 542 is embedded in one end of the hexagonal sleeve 541 facing away from the nut 520. The installer can clearly observe through the transparent window whether the one-way positioning block 550 is connected with the one-way positioning groove 531 to ensure that the anti-loosening structure can function properly. The adjustable protective component 540 also includes an adjustment module. The side end of the hexagonal sleeve 541 is provided with an annular groove communicating with the guide cavity 543. The interior of the hexagonal sleeve 541 is provided with two positioning grooves, both of which are communicating with the annular groove. The adjustment module includes an adjustment frame rotatably connected to the inside of the annular groove. An adjustment rope and a positioning spring are fixedly connected to the inner side of the adjustment frame. One end of the adjustment rope facing away from the adjustment frame is fixedly connected to the one-way positioning block 550. The positioning spring is engaged inside one of the positioning grooves. The elastic force of the positioning spring is greater than the sum of the elastic forces of all the metal springs 560.

[0051] When the user needs to adjust or remove nut 520, the user only needs to rotate the adjustment frame accordingly. The adjustment frame, along with the adjustment rope and positioning spring, rotates around the axis of the ring groove. Under the pull of the adjustment frame, the adjustment rope drives the one-way positioning block 550 away from the one-way positioning groove 531. When the positioning spring engages with another positioning groove and locks the adjustment frame at that angle, the one-way positioning block 550 is completely separated from the one-way positioning groove 531 and retracts into the guide cavity 543. At this time, nut 520 is no longer obstructed, and the user can adjust or remove nut 520 accordingly.

[0052] like Figure 1-8 As shown, an installation method for a rapid positioning and connection installation device for prefabricated building components is described below:

[0053] I. Installation of Embedded Parts:

[0054] The vertical embedded part 200 and the horizontal embedded part 300 are respectively embedded and cast into the ends of the precast column and the precast beam;

[0055] II. 100° positioning and installation of steel components:

[0056] a: Hoist the steel component 100 to the top of the vertical embedded part 200, ensuring that the through hole 400 on the steel component 100 is aligned with the through hole 400 of the vertical embedded part 200;

[0057] b: Pass the bolt 510 through the aligned through hole 400 to complete the vertical positioning of the steel component 100 and the vertical embedded part 200;

[0058] c: Screw the nut 520 into the shank of the bolt 510 until both are tightly against the steel component 100 and the vertical embedded part 200, respectively.

[0059] III. Horizontal positioning and installation of precast beams:

[0060] a: Hoist the precast beam and move the end with the horizontal embedded part 300 to the side of the steel component 100;

[0061] b: Adjust the position of the precast beam so that the through hole 400 on the steel component 100 is aligned with the through hole 400 of the horizontal embedded part 300;

[0062] c: Pass the bolt 510 through the aligned through hole 400 to complete the horizontal positioning of the steel component 100 and the horizontal embedded part 300.

[0063] d: Screw the nut 520 into the shank of the bolt 510 until both are tightly against the steel component 100 and the horizontal embedded part 300, respectively.

[0064] Working principle: During the process of screwing the nut 520 onto the surface of the bolt 510, the nut 520, through the adjustable protective component 540, can easily drive the one-way positioning block 550 to spiral towards the one-way positioning groove 531 on the round block 530. When the inclined surface of the one-way positioning block 550 abuts against the inclined angle of the round block 530, the inclined angle of the round block 530 can tilt and press the one-way positioning block 550 away from the round block 530, so that the one-way positioning block 550 can smoothly engage with the one-way positioning groove 531 during the movement. Furthermore, during the subsequent spiral movement of the nut 520... During the process, the inclined surface of the one-way positioning block 550 contacts and is squeezed against the inclined surface of the one-way positioning groove 531, causing the one-way positioning block 550 to continuously move in and out of the one-way positioning groove 531. When the nut 520 is tightened into place and the one-way positioning block 550 is engaged with the corresponding one-way positioning groove 531, the vertical surface of the one-way positioning groove 531 abuts against the vertical surface of the one-way positioning block 550. This effectively prevents the nut 520 from loosening along the surface of the bolt 510, making the threaded connector 500 run more stably and improving the stability of the vertical connection between the precast beam and the precast column.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
