Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to a connecting piece and a prefabricated building component. Background Art

[0002] In prefabricated buildings, grouting sleeves are important components used to connect the internal steel bars of prefabricated components. According to different grouting methods, grouting sleeves are mainly divided into two types: full grouting sleeves and semi grouting sleeves. Their application scenarios and their respective advantages are as follows:

[0003] Fully grouted sleeve: Suitable for most prefabricated construction projects, especially for those buildings that require higher structural strength and integrity, such as in high-rise buildings, bridges, large public facilities and other structures, in order to ensure that the connection parts have sufficient strength and rigidity. Its advantages: Higher connection strength: Fully grouted sleeves can provide a more stable connection because the entire sleeve is filled with grouting material to form a solid whole. Good durability: Since the grouting material can effectively protect the steel bars from corrosion, the durability of the connection parts is improved. Better seismic performance: Due to its better integrity, the fully grouted sleeve shows better stability and seismic resistance under extreme conditions such as earthquakes.

[0004] Semi-grouting sleeve: When the construction site space is limited or the construction conditions are more demanding, the use of semi-grouting sleeve can reduce the difficulty of construction and is suitable for projects that require quick installation, such as temporary buildings or emergency projects. Its advantages: Easy installation: One end of the semi-grouting sleeve is pre-filled with grouting material, and the other end is grouted at the construction site, which makes the installation process easier and faster. Cost-effectiveness: Compared with the full grouting sleeve, the semi-grouting sleeve has a lower cost, especially when a particularly high-strength connection is not required. Strong adaptability: In some occasions where full grouting operations cannot be performed (such as narrow spaces), semi-grouting sleeves provide a viable solution.

[0005] The choice of full grouting sleeve or semi grouting sleeve depends mainly on the specific requirements of the project and the site conditions. If the project has high requirements for the strength, durability and earthquake resistance of the structure, the full grouting sleeve should be given priority; if the project pays more attention to construction speed and cost control, the semi grouting sleeve can be considered. In practical applications, these two types of sleeves are sometimes used in combination to achieve the best effect.

[0006] The grouting sleeve in the prior art is a key connector for connecting steel bars in prefabricated components. However, the full grouting sleeve and the half grouting sleeve are both steel parts of specific shapes, and the two cannot be converted or assembled with each other. This means that in the production process of prefabricated components, the appropriate sleeve type must be selected according to the specific usage. This limitation not only increases the complexity and cost of prefabricated component production, but also adds additional attention points and workload in the subsequent installation process. Therefore, there is an urgent need to design a new type of universal grouting sleeve that can flexibly convert between the functions of the full grouting sleeve and the half grouting sleeve to simplify the production and installation process of prefabricated components and improve the overall construction efficiency. Summary of the invention

[0007] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0008] In view of the fact that the existing full grouting sleeves and semi grouting sleeves in the above-mentioned or prior art are both made of steel in specific shapes, and the two cannot be converted or assembled into each other, resulting in that when making prefabricated parts, they can only be selected according to the needs. This leads to problems that require special attention during production or subsequent installation, and the present invention is proposed.

[0013] As a preferred solution of the connecting piece of the present invention, the outer wall of the one-way opening tube is composed of a mounting section, a first convex section, a concave section and a second convex section from top to bottom, wherein the cross-section of the part composed of the first convex section, the concave section and the second convex section is bone-shaped.

[0014] As a preferred solution of the connecting piece of the present invention, a plurality of groups of blocking members are sequentially arranged on the inner wall of the outer cylinder from top to bottom, and each group of blocking members includes a plurality of blocking arch plates distributed in an annular manner with equal intervals.

[0015] As a preferred solution of the connecting piece of the present invention, the blocking arch plate is clamped to the recessed section or the installation section.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1, reference Figure 1-Figure 4 , which is the first embodiment of the present invention, provides a connecting piece, including an outer shell component 100 and an inner liner component 200 installed in the outer shell component 100, the outer shell component 100 includes an outer cylinder 101, and a grouting port 102 and a grouting port 103 opened on the outer wall of the outer cylinder 101; the inner liner component 200 includes a one-way opening cylinder 201 detachably installed at one end or inside of the outer cylinder 101.

[0035] In this embodiment, the present invention provides a new type of universal connector, which can realize the rapid conversion between the full grouting sleeve and the semi-grouting sleeve as a sleeve, significantly improving the flexibility and efficiency of the production and installation of prefabricated components. Specifically, by installing the one-way opening tube 201 at one end of the straight cylindrical body, a semi-grouting sleeve form can be formed. In this form, the one-way opening tube 201 is pre-filled with grouting material, and only the space between the outer cylinder 101 and the one-way opening tube 201 needs to be grouted, which is convenient for on-site grouting. By pushing the one-way opening tube 201 into the cylinder, a full grouting sleeve form can be formed. At this time, only grouting needs to be injected into the outer cylinder 101 to achieve the effect of full grouting. In this form, the one-way opening tube 201 located in the cylinder can also be used as an internal blocking member 106 to ensure that the connection between the steel bars is more secure and effectively prevent the steel bars from loosening or being pulled out.

[0036] This design achieves the following beneficial effects: (1) Improved construction flexibility: Prefabricated component manufacturers and installers can quickly select the most suitable grouting sleeve form according to the actual needs of the construction site, without having to decide in advance whether to use a full grouting sleeve or a half grouting sleeve, which greatly reduces the pre-construction preparation work. (2) Reduced costs: Since the same sleeve can be used to achieve two different functions, the demand for sleeve types is reduced, thereby reducing procurement costs and inventory management costs. (3) Simplified installation process: This universal sleeve design simplifies the production and installation process of prefabricated components, reduces the chance of errors, and improves construction efficiency. (4) Enhanced functionality: By simply adjusting the position of the one-way opening tube 201, the conversion between the full grouting sleeve and the half grouting sleeve can be achieved, which enhances the functionality and adaptability of the sleeve. (5) Improved construction quality: The design of the sleeve ensures that good connection strength and durability can be maintained regardless of whether it is in the full grouting or half grouting state, thereby improving the safety and reliability of the entire structure.

[0037] Example 2, reference Figures 2-3, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an outer cylinder 101 configured as a straight cylinder, with an annular upper cover plate 104 and a lower cover plate 105 respectively installed on the upper and lower parts, the grouting port 102 is located near the lower cover plate 105, and the slurry outlet 103 is located near the upper cover plate 104, wherein the upper cover plate 104 and the lower cover plate 105 are each inserted with a steel bar.

[0038] It should be noted that: the outer cylinder 101 is designed as a straight cylinder structure, with an annular upper cover plate 104 and a lower cover plate 105 installed at both ends. Further, a rubber ring can be set at the center of the upper cover plate 104 and the lower cover plate 105, and the rubber ring is used to seal the part where the steel bar is connected to it to avoid leakage of slurry. The upper cover plate 104 is located at the top of the outer cylinder 101, and is fixedly connected to the outer cylinder 101 by threads or other connection methods. A slurry outlet 103 is provided near the upper cover plate 104 for observing and ensuring that the grouting material is fully filled into the sleeve. The lower cover plate 105 is located at the bottom of the outer cylinder 101, and is also fixedly connected to the outer cylinder 101 by threads or other connection methods. A grouting port 102 is provided near the lower cover plate 105 for injecting grouting material into the sleeve. This design ensures the correct installation of the sleeve in the prefabricated component, and through the cooperation of the upper cover plate 104 and the lower cover plate 105, the grouting process can be effectively controlled. The position arrangement of the grouting port 102 and the grouting outlet 103 helps to ensure that the grouting material can be evenly distributed and completely fill the internal space of the sleeve, thereby ensuring the firmness and reliability of the steel bar connection.

[0039] The one-way open tube 201 is installed on the inner wall of the upper cover plate 104. The one-way open tube 201 is detachably connected to the inner wall of the upper cover plate 104. The one-way open tube 201 is coaxially arranged with the upper cover plate 104. One end of one steel bar is located inside the one-way open tube 201, forming a semi-grouting sleeve. The one-way open tube 201 is located inside the outer cylinder 101. Since the one-way open tube 201 is coaxially arranged with the upper cover plate 104, one end of one steel bar is located inside the one-way open tube 201, forming a full grouting sleeve.

[0040] A plurality of groups of blocking members 106 are sequentially arranged on the inner wall of the outer cylinder 101 from top to bottom, and each group of blocking members 106 includes a plurality of blocking arch plates 106a distributed in an annular manner with equal intervals.

[0041] It should be noted that in order to enhance the connection strength between the outer cylinder 101 and the concrete mortar and prevent the solidified concrete mortar from being pulled out from the inside of the outer cylinder 101, the present invention arranges multiple groups of blocking members 106 on the inner wall of the outer cylinder 101 from top to bottom, and each group of blocking members 106 includes a plurality of blocking arch plates 106a distributed in a ring with equal intervals, and these blocking arch plates 106a are bent inward.

[0042] Multiple groups of blocking members 106: From the top to the bottom of the outer cylinder 101, multiple groups of blocking members 106 are sequentially arranged along the length direction of the cylinder, so as to ensure that there are enough support points inside the entire outer cylinder 101 and enhance the contact area with the concrete mortar. Each group includes multiple blocking arch plates 106a: Each group of blocking members 106 is composed of multiple blocking arch plates 106a distributed in a ring with equal spacing. These blocking arch plates 106a are arranged in a ring along the inner wall of the outer cylinder 101 and are bent inward to form a structure similar to an arch bridge. The function of the blocking arch plate 106a: The design of the blocking arch plate 106a increases the friction and contact area between the outer cylinder 101 and the concrete mortar, and effectively prevents the solidified concrete mortar from being pulled out from the inside of the outer cylinder 101. The inward bending characteristics of the blocking arch plate 106a provide additional mechanical locking effect, further enhancing the stability of the connection.

[0043] This design not only improves the bonding strength between the outer cylinder 101 and the concrete mortar, but also increases the overall stability and durability of the outer cylinder 101, thereby ensuring the reliability of the steel bar connection in the prefabricated component. By adding these blocking arch plates 106a to the inner wall of the straight and smooth outer cylinder 101, the structural strength of the connection part can be significantly improved to prevent loosening or pulling out under stress.

[0044] The outer wall of the one-way opening tube 201 is composed of a mounting section 201a, a first convex section 201b, a concave section 201c and a second convex section 201d from top to bottom, wherein the cross section of the portion composed of the first convex section 201b, the concave section 201c and the second convex section 201d is bone-shaped.

[0045] It should be noted that in order to enhance the connection strength between the one-way opening tube 201 and the outer cylinder 101 and ensure the firm connection between the steel bars, the present invention designs the one-way opening tube 201 into a special shape. The outer wall of the one-way opening tube 201 is composed of a mounting section 201a, a first convex section 201b, a recessed section 201c and a second convex section 201d from top to bottom, wherein the mounting section 201a is located at the top end of the one-way opening tube 201 and is used to connect with the upper cover plate 104 to ensure that the one-way opening tube 201 can be stably installed at one end or inside of the straight cylindrical outer cylinder 101. The first convex section 201b is located below the mounting section 201a, and its diameter is slightly larger than that of the mounting section 201a, forming an outward expansion area, which helps to form a firm mechanical bite after pouring concrete. The recessed section 201c is located below the first convex section 201b, and its diameter is smaller than that of the first convex section 201b, forming an inward contraction area. This design can increase the friction between the one-way open cylinder 201 and the outer cylinder 101, and prevent the one-way open cylinder 201 from being displaced when subjected to external force. The second convex section 201d is located below the concave section 201c, and its diameter becomes larger again, forming another outward expansion area, which is similar to the function of the first convex section 201b, but at a lower position, further increasing the bite force with the concrete mortar.

[0046] The first convex section 201b, the concave section 201c and the second convex section 201d have a bone-shaped cross section. This bone-shaped cross section design forms a shape in which the diameter first widens, then narrows, and finally widens again, so that after the one-way open tube 201 is matched with the outer cylinder 101 and poured with concrete, the concrete mortar can tightly wrap the one-way open tube 201, especially the first convex section 201b and the second convex section 201d, to form a mechanical bite, thereby increasing the connection strength between the one-way open tube 201 and the outer cylinder 101. At the same time, this design also enhances the connection firmness between the upper and lower steel bars, ensuring the overall stability and durability of the prefabricated component.

[0047] Further: the blocking arch plate 106a is snapped into the recessed section 201c or the installation section 201a. In the full grouting sleeve form, the one-way opening tube 201 is pushed into the interior of the outer cylinder 101, and cooperates with the blocking member 106 inside the outer cylinder 101 to form an effective locking mechanism. Specifically: the inner wall of the outer cylinder 101 is provided with multiple groups of blocking members 106, each group of blocking members 106 is composed of multiple blocking arch plates 106a distributed in an annular manner with equal spacing, and the blocking arch plates 106a are arched in design, bent inward, and can be mutually snapped with specific parts on the one-way opening tube 201, so as to achieve locking. Since the blocking arch plates 106a are arched in design, when the one-way opening tube 201 is pushed in, the blocking arch plates 106a will be squeezed and deformed to adapt to the insertion of the one-way opening tube 201 until the one-way opening tube 201 is located between the blocking arch plates 106a.

[0048] The outer wall of the one-way opening tube 201 is composed of a mounting section 201a, a first convex section 201b, a concave section 201c and a second convex section 201d from top to bottom, wherein the first convex section 201b, the concave section 201c and the second convex section 201d form a bone-shaped cross section. When locking, the upper blocking arch plate 106a is stuck in the mounting section 201a. When the one-way opening tube 201 is pushed into the outer cylinder 101, the upper blocking arch plate 106a will be stuck on the mounting section 201a of the one-way opening tube 201, forming a preliminary locking. The middle blocking arch plate 106a is stuck in the concave section 201c. As the one-way opening tube 201 continues to be pushed in, the middle blocking arch plate 106a will be stuck on the concave section 201c, further enhancing the locking effect between the one-way opening tube 201 and the outer cylinder 101. When the one-way open tube 201 is completely in place, concrete mortar is filled between the outer tube 101 and the one-way open tube 201 through the grouting process. As the concrete mortar solidifies, the connection between the one-way open tube 201 and the outer tube 101 is further strengthened, ensuring a firm connection between the two.

[0049] This design ensures a stable connection between the one-way open tube 201 and the outer tube body 101 through the mutual clamping between the one-way open tube 201 and the blocking arch plate 106a, in combination with the solidified concrete mortar filled between the two, thereby enhancing the connection firmness between the steel bars and ensuring the overall stability and durability of the prefabricated component.

[0050] 1. Production and installation process of semi-grouting sleeve:

[0051] (1) Preparation stage:

[0052] The mounting section 201 a of the one-way opening tube 201 is screwed to the inner wall of the upper cover plate 104 .

[0053] The one-way opening cylinder 201 is inserted into the outer cylinder body 101 , and the upper cover plate 104 is screwed to the upper end of the outer cylinder body 101 .

[0054] The lower cover plate 105 is screwed to the lower end of the outer cylinder 101 .

[0055] (2) Semi-grouting stage:

[0056] One of the steel bars is inserted into the one-way open tube 201 .

[0057] Concrete mortar is injected into the one-way opening tube 201 through the grouting port 102 until the mortar overflows from the grouting port 103 to form a semi-grouting sleeve shape.

[0058] (3) Final grouting stage:

[0059] After the installation of the prefabricated building components is completed, concrete mortar is uniformly injected into the outer cylinder 101 and the one-way opening cylinder 201 through the grouting port 102 until the mortar overflows from the grouting port 103 to ensure the strength and durability of the connection.

[0060] 2. Manufacturing and installation process of full grouting sleeve:

[0061] (1) Preparation stage:

[0062] The one-way opening cylinder 201 is pushed into the outer cylinder body 101 so that the recessed section 201 c thereof corresponds to the blocking member 106 in the middle.

[0063] The upper cover plate 104 is screwed to the upper end of the outer cylinder 101 .

[0064] The lower cover plate 105 is screwed to the lower end of the outer cylinder 101 .

[0065] (2) Full grouting stage:

[0066] One of the steel bars is passed through the upper cover plate 104 and inserted into the one-way open tube 201 .

[0067] A fully grouting sleeve is formed.

[0068] (3) Final grouting stage:

[0069] After the installation of the prefabricated building components is completed, concrete mortar is uniformly injected into the outer cylinder 101 and the one-way opening cylinder 201 through the grouting port 102 until the mortar overflows from the grouting port 103 to ensure the strength and durability of the connection.

[0070] Through the above steps, the steel bars in the prefabricated building components can be reliably connected through the semi-grouting sleeve or the full-grouting sleeve. In the semi-grouting sleeve form, part of the mortar is pre-filled in the one-way open tube 201, and in the full-grouting sleeve form, the one-way open tube 201 and the multiple groups of blocking members 106 act together as a blocking assembly that is mutually reversely engaged and limited and is placed in the outer cylinder 101, thereby ensuring the integrity of the connection part in the final grouting stage and preventing the steel bar from detaching. This method improves the flexibility and efficiency of the production and installation of prefabricated components, and ensures the structural strength and durability of the connection part.

[0071] In order to further increase the contact area between the outer cylinder 101 and the prefabricated part and ensure the firmness of the outer cylinder 101 installed in the prefabricated part, the present invention provides a spiral groove 107 on the outer wall of the outer cylinder 101. The design of the spiral groove 107 increases the contact area between the outer cylinder 101 and the concrete of the prefabricated part, which helps to improve the bite force between the outer cylinder 101 and the concrete. The existence of the spiral groove 107 makes the outer surface of the outer cylinder 101 no longer smooth, but forms a plurality of points of contact with the concrete, which can be better embedded in the concrete after the concrete hardens, thereby increasing the friction and connection strength between the outer cylinder 101 and the prefabricated part. This design not only improves the connection strength between the outer cylinder 101 and the prefabricated part, but also ensures the stability and firmness of the outer cylinder 101 inside the prefabricated part. Even when subjected to external forces, the outer cylinder 101 is not easily displaced or loosened, thereby ensuring the reliability of the steel bar connection and the safety of the entire structure, and can significantly increase the contact area between the outer cylinder 101 and the prefabricated parts, improve the structural strength and durability of the connection parts, and ensure the overall stability and reliability of the prefabricated components.

[0072] Example 3

[0073] Reference Figure 5 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a prefabricated building component. The distribution of steel bars and grouting sleeves inside the prefabricated building component is as follows: Main reinforcement: longitudinal and transverse main reinforcements are mainly arranged inside the prefabricated building component to provide the basic structural strength of the prefabricated building component. Distribution reinforcement: distribution reinforcements are arranged between the main reinforcements to increase the overall stability and crack resistance of the prefabricated building component. Connection reinforcement: connection reinforcements are embedded in the edge of the prefabricated building component for connection with other prefabricated building components or structural parts.

[0074] Connection parts distribution: Position layout: Connection parts are usually distributed at the edge of prefabricated building components and are used to connect the steel bars of adjacent prefabricated building components or structural parts. Quantity determination: The number of connection parts is determined according to the size and load-bearing requirements of prefabricated building components to ensure the strength and stability of the connection of prefabricated building components. Spacing requirements: The spacing between connection parts must meet the requirements of the design specifications to ensure the uniform distribution of the connection parts and the integrity of the structure.

[0075] The production process sequence of prefabricated building components:

[0076] (1) Mold preparation: Prepare the mold for prefabricated building components and ensure that the mold is flat and undamaged. Coat the mold surface with a release agent to facilitate subsequent demoulding.

[0077] (2) Fabrication of steel bar skeleton: Fabricate the steel bar skeleton according to the design drawings to ensure the accuracy of the steel bar size and position. Tie the main bars, distribution bars and connecting bars into shape according to the design requirements.

[0078] (3) Pre-embedded connectors: Pre-embed connectors at corresponding positions of the steel frame according to design requirements. Ensure that the connectors are accurately and firmly positioned.

[0079] (4) Concrete pouring: Place the steel skeleton in the mold and start pouring concrete. Use a vibrating rod to vibrate the concrete to ensure that the concrete is dense and has no voids. Control the height and speed of concrete pouring to avoid bubbles.

[0080] (5) Maintenance: After pouring, the prefabricated building components are covered and maintained to ensure that the concrete is fully hardened. Regular inspections are required during the maintenance period to ensure that the concrete surface is moist.

[0081] (6) Demolding and inspection: After reaching a certain strength, demoulding is carried out. The appearance of prefabricated building components is inspected and the dimensions are measured to ensure that they meet the design requirements.

[0082] (7) Transportation and storage: Use special equipment to lift the prefabricated building components onto the transport vehicle. When storing prefabricated building components, ensure that they are stacked stably to avoid damage.

[0083] (8) On-site installation: At the construction site, use lifting equipment to lift the prefabricated building components to the designated location. The prefabricated building components are connected through full grouting sleeves or semi-grouting sleeves to complete the final installation.

[0084] (9) Grouting connection: Select the form of full grouting sleeve or half grouting sleeve as needed.
