Description

Technical Field

[0001] This utility model relates to the technical field of precast concrete components, specifically to an assembly structure for precast concrete components. Background Technology

[0002] Precast concrete, also known as pre-fabricated concrete, refers to pre-made concrete components that are assembled and installed on-site. It can be divided into two methods: on-site precasting and factory precasting. Precast concrete components refer to assembled concrete components that are completed before installation on the construction site. Common examples include precast concrete floor slabs, concrete box girders for bridges, precast concrete roof trusses for industrial plants, culvert frames, and precast concrete piles for foundation treatment.

[0003] Typically, multiple precast concrete components need to be spliced ​​using appropriate mechanisms. An existing precast concrete component splicing structure, such as the one described in patent publication number CN217782562U, includes a second reinforcing bar and a second connecting groove. Grouting material can be used to fix the second reinforcing bar and the second connecting groove together, thus firmly splicing two precast concrete components together in the left-right direction. Simultaneously, a first connecting groove, a connecting plate, and a first reinforcing bar are provided. Grouting material can be used to fix the first connecting groove and the first reinforcing bar together, thus firmly splicing two precast concrete components together in the vertical direction. This increases the splicing area, improves the splicing strength, and prevents breakage at the splice joint.

[0004] However, the device requires steel bar insertion, the connection is not secure, and the extension direction is relatively limited, making it impractical. Utility Model Content

The upper and lower ends of the intersection of the X-axis component and the Y-axis component are respectively connected to the inner ends of a set of Z-axis components. A set of splicing threaded grooves is provided inside the outer ends of the X-axis component, the Y-axis component, and the Z-axis component. A through groove is provided in the middle of one outer end of each of the X-axis component, the Y-axis component, and the Z-axis component.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a prefabricated concrete component splicing structure, which has the following beneficial effects:

[0014] The system allows for X-axis extension via the X-axis component, Y-axis extension via the Y-axis component, and Z-axis extension via the Z-axis component. When rebar splicing is required in a specific direction, a set of rebar kits can be screwed into the splicing thread groove of the corresponding X-axis, Y-axis, or Z-axis component by rotating the installation thread head. This aligns the limiting thread groove with the through groove. Then, the limiting stud is passed through the limiting thread groove and screwed into the limiting thread groove by external action of the limiting screw head, thus circumferentially fixing the installation thread head. This forms a fixed rebar kit in that direction, and the rebar kit can be further used to connect and fix the rebar. This system features three-dimensional multi-directional extension, and the screwing and anti-rotation self-locking mechanisms make the splicing more stable and improve reliability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Please see Figure 1-4A precast concrete component splicing structure includes an X-axis component 1, a Y-axis component 2, a Z-axis component 3, a splicing threaded groove 4, a through groove 5, an installation threaded head 6, a rebar kit 7, a limiting screw head 8, a limiting stud 9, and a limiting screw groove 16. The middle parts of the left and right ends of the X-axis component 1 are respectively connected to the inner ends of a set of Y-axis components 2. The upper and lower ends of the intersection of the X-axis component 1 and the Y-axis component 2 are respectively connected to the inner ends of a set of Z-axis components 3. A set of splicing threaded grooves 4 are provided inside the outer ends of the X-axis component 1, the Y-axis component 2, and the Z-axis component 3, and a set of through grooves 5 are provided in the middle of one outer end of the X-axis component 1, the Y-axis component 2, and the Z-axis component 3. The Z-axis component 3 and the installation threaded head 6 are detachably screwed together. The outer end of the installation threaded head 6 is connected to the inner end of the rebar kit 7, and a certain groove is provided in the middle of the outer side of the installation threaded head 6. The limiting screw groove 16 connects the outer end of the limiting stud 9 to the middle of the inner end of the limiting screw head 8. The limiting stud 9 passes through the through groove 5 and is detachably screwed into the limiting screw groove 16. It can extend in the X direction through the X-direction member 1, in the Y direction through the Y-direction member 2, and in the Z direction through the Z-direction member 3. When it is necessary to splice the reinforcing bars in the corresponding direction, a set of reinforcing bar kits 7 can be rotated through the installation thread head 6 to be screwed into the splicing thread groove 4 of the corresponding X-direction member 1, Y-direction member 2, or Z-direction member 3, so that the limiting screw groove 16 corresponds to the through groove 5. Then, the limiting stud 9 passes through the limiting screw groove 16 and is screwed into the limiting screw groove 16 by external rotation of the limiting screw head 8, which fixes the installation thread head 6 circumferentially, thereby fixing the reinforcing bar kit 7 in that direction. The reinforcing bar kit 7 can be further fixed by connecting the reinforcing bars.

[0023] It also includes a tightening sleeve 10, a tightening screw 11, and a tightening head 12. The outer middle part of the rebar kit 7 is connected to the inner side of the tightening sleeve 10. The inner wall of the tightening sleeve 10 is screwed to the outer wall of the tightening screw 11. The outer side of the tightening screw 11 is connected to the inner middle part of the tightening head 12. When the rebar is fitted inside the rebar kit 7, the tightening head 12 can be turned to rotate the tightening screw 11. The tightening screw 11, after being screwed into the tightening sleeve 10, extends inward into the rebar kit 7 and tightens the outer side of the rebar.

[0024] It also includes a sealing plug 13, a limiting piece 14, and a pull ring 15. The sealing plug 13 is detachably inserted into the splicing thread groove 4. The outer side of the sealing plug 13 is connected to the middle of the inner side of the limiting piece 14. The middle of the outer side of the limiting piece 14 is connected to the inner side of the pull ring 15. The sealing plug 13 can be inserted into the splicing thread groove 4 of the unused X-direction component 1, Y-direction component 2, or Z-direction component 3 for sealing and protection. It is blocked by the outer side of the limiting piece 14. The hook pull ring 15 can connect to the limiting piece 14 to pull out the sealing plug 13, thereby improving reliability.

[0025] X-axis component 1, Y-axis component 2, Z-axis component 3, splicing threaded groove 4, through groove 5, installation threaded head 6, rebar kit 7, limiting screw head 8, limiting stud 9, tightening screw sleeve 10, tightening screw 11, tightening screw head 12, and limiting screw groove 16 are all made of hard stainless steel alloy; this increases the rigidity of the overall component, making it less prone to deformation, breakage, and damage, and also has strong resistance to oxidation and corrosion, thus improving reliability.

[0026] In summary, when using a precast concrete component splicing structure, it can extend in the X direction via X-axis component 1, in the Y direction via Y-axis component 2, and in the Z direction via Z-axis component 3. When splicing of reinforcing bars in the corresponding direction is required, a set of reinforcing bar kits 7 can be screwed into the splicing thread grooves 4 of the corresponding X-axis component 1, Y-axis component 2, or Z-axis component 3 by rotating the installation thread head 6, so that the limiting thread groove 16 corresponds to the through groove 5. Then, the limiting stud 9 is passed through the limiting thread groove 16 and screwed into the limiting thread groove 16 by external rotation of the limiting screw head 8, thus fixing the installation thread head 6 circumferentially. The steel reinforcement kit 7 is fixed in this direction, and can be further fixed by connecting steel reinforcements to the steel reinforcement kit 7. After the steel reinforcement is connected inside the steel reinforcement kit 7, the tightening head 12 can be turned to rotate the tightening screw 11. The tightening screw 11 is screwed into the tightening screw sleeve 10 and extends inward into the steel reinforcement kit 7 to tighten the outside of the steel reinforcement. In addition, the unused X-direction component 1, Y-direction component 2 or Z-direction component 3 splicing thread groove 4 can be sealed and protected by a sealing plug 13, which is blocked by the outside of the limiting piece 14. The hook pull ring 15 can be connected to the limiting piece 14 to pull out the sealing plug 13, thereby improving reliability.
