Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a connection node of a prefabricated beam and a prefabricated wall panel. Background Art

[0002] At present, in order to meet the needs of production and manufacturing, there are a large number of temporary buildings. Temporary building structures are usually assembled from container structures or overlapped with color steel plates. They have poor sound insulation, weak structural bearing capacity and are prone to rust. Compared with concrete buildings, the living experience is poor.

[0003] In the construction of conventional cast-in-place concrete buildings, when constructing structural beams and shear walls, the steel bars of the structural beams and shear walls are usually tied together and the concrete is poured at one time. Support frames need to be built on site and a large amount of wet work needs to be carried out. The construction process is complicated, and the structural beams and walls cannot be disassembled or installed after the construction is completed.

[0004] The prefabricated beam structure of conventional prefabricated buildings is hoisted and overlapped on the structural columns at both ends, and then grouting liquid is poured between the structural beam and the prefabricated wall panels to achieve the connection between the prefabricated beam structure and the prefabricated wall panels. The connection nodes formed by this construction method cannot be disassembled from the prefabricated wall panels at a later stage, nor can they be reused. Utility Model Content

[0005] Based on the above description, the utility model provides a connection node between a prefabricated beam and a prefabricated wall panel to solve the problem that the prefabricated beam and the prefabricated wall panel are difficult to disassemble and repeatedly assemble.

[0009] Furthermore, the long slot includes a basic slot and a widened slot that are interconnected, the width of the widened slot is greater than the width of the basic slot, and the mounting screw can pass through the basic slot and be inserted into the widened slot;

[0010] The installation screw rod is also threadedly connected with a fixing nut. When the prefabricated beam is installed above the prefabricated wall panel, a partial area of ​​the prefabricated beam is clamped between the installation nut and the fixing nut.

[0011] Furthermore, the side walls of the mounting nut are in contact with the side walls of the widened groove, and the threaded hole in the middle of the mounting nut is aligned with the basic groove.

[0012] Furthermore, the height of the mounting nut is lower than the height of the widening groove.

[0013] Furthermore, the mounting hole comprises a first accommodating hole and a second accommodating hole which are interconnected, the first accommodating hole is used to accommodate a fixing nut, and the second accommodating hole is used to accommodate a mounting screw.

[0014] Further, the shape of the first receiving hole matches the shape of the fixing nut, and the height of the first receiving hole is consistent with the height of the fixing nut.

[0026] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0028] A connection node between a precast beam and a precast wall panel, referring to Figures 1 to 3 , including a prefabricated wall panel 1 and a prefabricated beam 2 installed on the prefabricated wall panel 1, a long groove 21 is opened inwardly on the side wall of the prefabricated beam 2 facing the prefabricated wall panel 1, the long groove 21 includes a basic groove 211 and a widening groove 212 that are interconnected, the width of the widening groove 212 is greater than the width of the basic groove 211, and the basic groove 211 is opened inwardly from the side wall of the prefabricated beam 2, and the widening groove 212 is arranged in the prefabricated beam 2.

[0029] A mounting nut 3 is provided in the widening groove 212 , and the mounting nut 3 can move horizontally along the widening groove 212 . In addition, the side walls of the mounting nut 3 are in contact with the side walls of the widening groove 212 , making it difficult for the mounting nut 3 to rotate in the widening groove 212 .

[0030] An installation hole 11 is opened at one end of the prefabricated wall panel 1 facing the prefabricated beam 2. The installation hole 11 includes a first receiving hole 111 and a second receiving hole 112 which are connected. The first receiving hole 111 is opened at the end surface of the prefabricated wall panel 1, and the second receiving hole 112 is located inside the prefabricated wall panel 1.

[0031] An installation screw 4 is also provided between the prefabricated beam 2 and the prefabricated wall panel 1, and a fixing nut 5 is threadedly sleeved on the installation screw 4. The width of the fixing nut 5 is greater than the width of the base groove 211, and the first accommodating hole 111 is used for the fixing nut 5 to be inserted, and the second accommodating hole 112 is used for the installation screw 4 to be inserted.

[0032] When installing the prefabricated beam 2, firstly, at the stacking point of the prefabricated beam 2, the installation screw 4 is passed through the basic groove 211 and then inserted into the widening groove 212, and is threadedly connected with the installation nut 3. Among them, the threaded hole in the middle of the installation nut 3 is aligned with the basic groove 211, and the side wall of the installation nut 3 is close to the side wall of the widening groove 212 and is difficult to rotate, so that the installation screw 4 can be threadedly connected with the installation nut 3 more smoothly. Preferably, the height of the widening groove 212 is greater than the height of the installation nut 3, so that the installation screw 4 can extend out of the installation nut 3, and the connection stability between the installation nut 3 and the installation screw 4 is improved.

[0033] After the installation screw rod 4 is connected with the installation nut 3, the prefabricated beam 2 is hoisted above the prefabricated wall panel 1. At this time, there is a gap between the fixing nut 5 and the side wall of the prefabricated beam 2. Pushing the installation screw rod 4 can drive the installation nut 3 to slide along the long groove 21.

[0034] The connection node of the present application is one of the node structures of a complete set of assembled assembly structures, and the other connection node structures are disclosed in other utility models. In the present building system, when installing the prefabricated beam 2, the prefabricated beam 2 is first clamped with the structural columns at both ends, and then gradually lowered to contact and connect with the prefabricated wall panel 1. Therefore, after the prefabricated beam 2 contacts the structural column, it cannot achieve the overall horizontal movement of the prefabricated beam 2 during the process of being lowered to contact with the prefabricated wall panel 1. In order to achieve smoother insertion of the installation screw 4 into the installation hole 11 during the installation process, the position of the installation screw 4 needs to be fine-tuned.

[0035] By pushing the mounting screw 4 to move along the long groove 21, it can be aligned with the mounting hole 11 below. After alignment, the fixing nut 5 is tightened until it abuts against the bottom wall of the prefabricated beam 2. At this time, a partial area of ​​the prefabricated beam 2 is clamped between the mounting nut 3 and the fixing nut 5 to fix the horizontal position of the mounting screw 4.

[0036] The prefabricated beam 2 is further lowered, so that the protruding portion of the installation screw rod 4 is inserted into the second receiving hole 112, and the fixing nut 5 is inserted into the first receiving hole 111, wherein the shape of the first receiving hole 111 matches the shape of the fixing nut 5, and the height of the first receiving hole 111 is consistent with the height of the fixing nut 5. By setting the shape of the first receiving hole 111 to be consistent with the shape of the fixing nut 5, the horizontal displacement of the fixing nut 5 is restricted, thereby realizing the horizontal limit between the prefabricated beam 2 and the prefabricated wall panel 1; the height of the first receiving hole 111 is consistent with the height of the fixing nut 5, so that the fixing nut 5 does not protrude from the surface of the prefabricated wall panel 1 after being inserted into the first receiving hole 111, nor is it recessed in the surface of the prefabricated wall panel 1, which is more beautiful and it is not easy for water to seep between the prefabricated wall panel 1 and the prefabricated beam 2.

[0037] In a more preferred embodiment, the length of the mounting screw 4 is equal to the sum of the height of the long groove 21 and the height of the mounting hole 11. Such a design allows the top of the mounting screw 4 to be tightly pressed against the top wall of the long groove 21 and the bottom to be tightly pressed against the bottom wall of the second accommodating hole 112 after the prefabricated beam 2 is installed on the prefabricated wall panel 1, thereby making the mounting screw 4 more stable and the pressure on the prefabricated beam 2 able to be transmitted to the prefabricated wall panel 1 through the mounting screw 4. In addition, after the prefabricated beam 2 is installed on the prefabricated wall panel 1, the bottom wall of the prefabricated beam 2 can be fitted with the top wall of the prefabricated wall panel 1, resulting in a better aesthetic appearance after installation.

[0038] When the installation screw 4 and the fixing nut 5 are inserted into the installation hole 11, the installation of the connection node here is completed. Between the prefabricated beam 2 and the prefabricated wall panel 1 of the present application, multiple connection nodes of the present application are arranged at intervals along the length extension direction of the prefabricated beam 2. The connection between the prefabricated beam 2 and the prefabricated wall panel 1 is achieved by multiple installation screws 4. Multiple installation screws 4 restrict and constrain each other, so that the connection between the prefabricated beam 2 and the prefabricated wall panel 1 is more stable and the connection strength is higher.

[0039] In addition, since multiple mounting screws 4 are provided on the prefabricated beam 2, after the prefabricated beam 2 is installed to the structural columns at both ends, the prefabricated beam 2 cannot move horizontally as a whole, and multiple mounting screws 4 need to be inserted into the mounting holes 11 one by one. Therefore, the long groove 21 is designed so that the position of the mounting screw 4 can be adjusted to achieve the smooth installation of multiple mounting screws 4.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
