Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology; more specifically, it relates to a prefabricated reinforced concrete joint. Background Technology

[0002] Precast construction is a relatively mature construction model. The building components are made directly in the factory and then assembled. It can realize large-scale and rapid production and construction, with high efficiency and good economic benefits, and has been widely used. The precast reinforced concrete joint is a key point in the assembly process and plays an important role in ensuring safety.

[0003] Currently, in the use of prefabricated nodes, the connection between the node and the beam usually uses grouting sleeve connection technology, which makes the connection operation cumbersome, time-consuming and labor-intensive, reducing the practicality of the equipment to a certain extent. In addition, it is impossible to provide auxiliary support for the beam after connection, making the equipment less stable during use and reducing its stability to a certain extent. Therefore, there is an urgent need for a prefabricated reinforced concrete node to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a prefabricated reinforced concrete joint to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a prefabricated reinforced concrete joint, comprising:

[0006] A horizontal node, wherein a locking structure is provided inside the horizontal node, a connecting structure is provided on the outside of the horizontal node, and a supporting structure is provided at the bottom of the horizontal node;

[0007] The locking structure includes a connecting groove, which is located inside the transverse node, and multiple sets of connecting grooves are provided.

[0008] The connecting structure includes a crossbeam, and connecting plates are fixedly connected to the upper and lower ends of both sides of the crossbeam. A groove is provided at one end of the connecting plate that is closer to the other side, and the external dimensions of the connecting plate are the same as the internal dimensions of the connecting groove.

[0009] The support structure includes a support column, and the support column is fixedly connected to the bottom end of the transverse node.

[0010] Preferably, the locking structure further includes a locking groove, which is located at one end of the connecting groove. The locking groove contains a spring and a locking block. The position of the locking groove corresponds to the position of the groove. The locking block is inclined on one side, with the inclined surface of the locking block facing the opening of the connecting groove. The external dimensions of the locking block are adapted to the internal dimensions of the groove. This design allows the locking block to be squeezed back into the locking groove by the outer surface of one end of the connecting plate against the inclined surface of the locking block when the connecting plate is inserted into the connecting groove.

[0011] Preferably, a limiting circular plate is fixedly connected to the bottom surface of the locking block, and the external dimensions of the limiting circular plate are adapted to the internal dimensions of the locking groove. The two ends of the spring abut against the bottom surface of the limiting circular plate and the bottom of the inner wall of the locking groove, respectively. This design can make the movement of the locking block more stable.

[0012] Preferably, the support structure further includes a positioning groove, which is formed inside the support column, and multiple sets of positioning grooves are provided. A lifting plate is inserted into the positioning groove, and a through groove is formed at both the upper and lower ends of one side of the lifting plate. An insertion groove is formed on one side of the positioning groove, and a movable groove is formed on the other side of the positioning groove. The positions of the insertion groove and the movable groove correspond to each other. An insertion plate is inserted into the insertion groove, and a spring piece and a spring plate are provided inside one end of the insertion plate. This design allows the lifting plate to be easily inserted into the positioning groove and can be positioned.

[0013] Preferably, the internal dimensions of both ends of one side of the lifting plate are adapted to the internal dimensions of the positioning groove, and the internal dimensions of the through groove and the insertion groove are adapted to the external dimensions of the insertion plate. This design facilitates the insertion of the lifting plate into the positioning groove and the insertion plate into the through groove and the insertion groove.

[0014] Preferably, the height of the inner part of the movable groove is greater than the height of the outer part of the insertion plate. The spring plate is hinged to the inner part of one end of the insertion plate, and the bottom surface of the spring plate abuts against the top surface of the spring piece. This design allows sufficient space when the spring plate pops up, facilitating the positioning operation of the entire lifting plate.

[0015] The technical effects and advantages of this utility model are as follows: This utility model inserts a connecting plate on one side of the crossbeam into the inside of the connecting groove. When the connecting plate contacts the inclined surface of the locking block, the locking block can move downward until the connecting plate moves to the bottom of the connecting groove. Under the action of the spring, the locking block can be locked into the inside of the groove, thereby achieving the purpose of overall positioning of the crossbeam. This design can form a connection between the crossbeam and the transverse node, which is convenient for workers to quickly install it, saving time and manpower, and improving the practicality of the equipment to a certain extent.

[0016] By inserting the lifting plate into the positioning groove and ensuring its bottom end contacts the bottom end of the groove, one end of the insertion plate is then inserted into the positioning groove from the insertion groove, passing through the through groove into the movable groove. The elasticity of the spring plate allows it to lift the spring plate, causing one end to press against the inner wall of the movable groove. This design facilitates the installation of the lifting plate on one side of the support column, providing auxiliary support for the connected crossbeam and enhancing the stability of the equipment during use. It also improves overall equipment stability and features a simple, reasonable, and highly practical design, making it easy to promote and apply. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The prefabricated buildings involved in this utility model are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] like Figures 1-3 As shown, this embodiment proposes a prefabricated reinforced concrete joint, including:

[0027] A horizontal node 1 has a locking structure 2 inside, a connecting structure 3 on the outside, and a supporting structure 4 at the bottom.

[0028] The locking structure 2 includes a connecting groove 21, which is located inside the transverse node 1, and multiple sets of connecting grooves 21 are provided.

[0029] The connecting structure 3 includes a crossbeam 31, and connecting plates 32 are fixedly connected to the upper and lower ends of both sides of the crossbeam 31. A groove 33 is provided at one end of the connecting plate 32 that is relatively close to the other end, and the external dimensions of the connecting plate 32 are the same as the internal dimensions of the connecting groove 21.

[0030] The locking structure 2 also includes a locking groove 22, which is located at one end of the connecting groove 21. A spring 23 and a locking block 24 are provided inside the locking groove 22. The position of the locking groove 22 corresponds to the position of the groove 33. The locking block 24 is inclined on one side, and the inclined surface of the locking block 24 faces the opening of the connecting groove 21. The external dimensions of the locking block 24 are adapted to the internal dimensions of the groove 33. A limiting circular plate is fixedly connected to the bottom surface of the locking block 24, and the external dimensions of the limiting circular plate are adapted to the internal dimensions of the locking groove 22. The two ends of the spring 23 abut against the bottom surface of the limiting circular plate and the bottom end of the inner wall of the locking groove 22, respectively.

[0031] In this embodiment, when the thrust of the connecting plate 32 is greater than the elasticity of the spring 23, the outer surface of one end of the connecting plate 32 can press against the single-sided inclined surface of the locking block 24, causing the locking block 24 to retract. Through the design of the limiting circular plate, the movement of the locking block 24 is more stable, and the locking block 24 can be prevented from dislodging from the locking groove 22. At the same time, the elasticity of the spring 23 can cause the locking block 24 to reset itself and insert the locking block 24 outward into the groove 33, thereby achieving the purpose of positioning the connecting plate 32.

[0032] Example 2

[0033] like Figures 4-6 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0034] The support structure 4 includes a support column 41, which is fixedly connected to the bottom end of the transverse node 1. The support structure 4 also includes a positioning groove 42, which is formed inside the support column 41. Multiple sets of positioning grooves 42 are provided. A support plate 43 is inserted into the positioning groove 42, and through grooves 44 are formed at both the upper and lower ends of one side of the support plate 43. An insertion groove 45 is formed on one side of the positioning groove 42, and a movable groove 46 is formed on the other side. The insertion groove 45 and the movable groove 46 are positioned... Correspondingly, an insertion plate 47 is inserted into the insertion slot 45, and a spring piece 48 and a spring plate 49 are provided inside one end of the insertion plate 47. The internal dimensions of both ends of one side of the lifting plate 43 are adapted to the internal dimensions of the positioning slot 42. The internal dimensions of the through slot 44 and the insertion slot 45 are adapted to the external dimensions of the insertion plate 47. The internal height of the movable slot 46 is greater than the external height of the insertion plate 47. The spring plate 49 is hinged to the inside of one end of the insertion plate 47, and the bottom surface of the spring plate 49 abuts against the top surface of the spring piece 48.

[0035] In this embodiment, the design allows the outer surfaces of both ends of one side of the lifting plate 43 to be inserted into the positioning groove 42. This keeps the through groove 44, the insertion groove 45, and the movable groove 46 in a horizontally corresponding position. At the same time, the outer surface of the insertion plate 47 can be inserted into the through groove 44, the insertion groove 45, and the movable groove 46, making the insertion plate 47 more stable when inserted. When the outer surface of one end of the insertion plate 47 is inserted into the movable groove 46, the elasticity of the spring piece 48 drives the spring plate 49 to hinge and flip upward. At this time, the spring plate 49 unfolds inside the movable groove 46, making it impossible for the insertion plate 47 to retract outward.

[0036] Working principle: When the equipment is in use, the connecting plates 32 at both ends of one side of the crossbeam 31 are simultaneously inserted into the interior of the connecting groove 21. At this time, the connecting plates 32 will contact the inclined surface of the locking block 24. When the pushing force of the connecting plates 32 is greater than the elastic force of the spring 23, the locking block 24 can be retracted, leaving enough space inside the connecting groove 21 to facilitate the connecting plates 32 to be inserted into the bottom position inside the connecting groove 21. When the connecting plates 32 move to the bottom position of the connecting groove 21, the position between the groove 33 and the locking groove 22 corresponds. At this time, under the action of the spring 23, the locking block 24 moves outward and is inserted into the interior of the groove 33, thereby achieving the purpose of positioning the connecting plates 32. In this way, the connection operation between the transverse node 1 and the connecting structure 3 can be performed, and multiple sets of transverse nodes 1 and connecting structures 3 can be spliced ​​together for use.

[0037] When using the equipment, the lifting plate 43 is inserted into the top of the positioning groove 42 until it contacts the inner wall of the positioning groove 42. Then, it can be moved downwards to fully insert the lifting plate 43 into the positioning groove 42, so that the through groove 44, the insertion groove 45, and the movable groove 46 are in horizontally corresponding positions. Then, the insertion plate 47 is inserted from the inside of the insertion groove 45 and passes through the inside of the through groove 44 until the outer surface of one end of the insertion plate 47 enters the inside of the movable groove 46. At this time, the inner height of the movable groove 46 is greater than the outer height of the insertion plate 47, so that the spring plate 49 can be hinged and rotated inside the movable groove 46 under the elastic action of the spring piece 48. This allows one end of the spring plate 49 to abut against the inner wall of the movable groove 46, thereby positioning the lifting plate 43 and the support column 41. Thus, the lifting plate 43 can be used to effectively assist in supporting the crossbeam 31. The above is the complete working principle of this utility model.

[0038] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0039] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0040] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
