[0002] The precast assembled wall panel is a wall assembled on site using precast components and is part of the precast building. The precast assembled wall panel has a wide range of applications and is suitable for steel structure buildings with industrialized development, meeting the requirements of heat insulation, impermeability, and sound insulation of building envelope structures. In addition, the precast assembled wall panel can be made in different sizes according to different buildings and has the characteristics of heat insulation, fire prevention, waterproofing, long service life, and good overall performance. Therefore, it is widely used in the external walls of various buildings such as hospitals, schools, shopping malls, banks, residential buildings, office buildings, and apartments.

[0003] The precast assembled wall panel not only improves the construction efficiency and quality by assembling precast components on site but also reduces on-site noise and pollution, meeting the requirements of green construction. It is an indispensable part of modern buildings.

[0004] For the existing precast assembled wall panels, generally, after one wall panel is assembled, the installation of the second panel is carried out immediately. When it is found that the two wall panels are misaligned and need to be adjusted, due to the large overall mass of the panels, the adjustment is rather troublesome and requires a large amount of manpower, resulting in an increased labor intensity and a cumbersome construction process with a long construction period. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a connecting node between a precast concrete fence and a precast concrete fence foundation to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A connecting node between a precast concrete fence and a precast concrete fence foundation includes a precast wall panel and a precast cup foundation, and the precast wall panel and the precast cup foundation are connected and assembled through a fitting component and a fastening component.

[0008] When the precast wall panel is installed into the precast cup foundation, the fitting component can make the connection between the two more stable by utilizing the gravity of the precast wall panel.

[0009] The fastening component is used to keep the bottom of the precast wall panel in contact with the bottom wall of the precast cup foundation.

[0010] A transverse movement limiting assembly is also provided between the prefabricated wall panel and the prefabricated cup-shaped foundation, and the transverse movement limiting assembly can prevent the prefabricated wall panel and the prefabricated cup-shaped foundation from sliding out of position after installation.

[0016] The matching opening is opened along the inner side wall direction of the prefabricated cup opening base.

[0017] As a further solution of the utility model:

[0018] During the process of inserting the wedge protrusion into the matching opening, the wedge protrusion and the matching opening will be closely fitted under the action of gravity of the prefabricated wall panel, so that the prefabricated wall panel and the prefabricated cup opening foundation can be preassembled.

[0019] As a further solution of the utility model:

[0020] The fastening assembly comprises an L-shaped slide groove which is arranged at the top edge of the prefabricated cup mouth base along the length direction of the prefabricated cup mouth base and a detachable prefabricated block which is arranged in the L-shaped slide groove.

[0021] An internal threaded sleeve is pre-embedded on the basis of the prefabricated cup mouth and on one side of the L-shaped slide groove, and a through hole corresponding to the internal threaded sleeve is opened on the prefabricated block, which can be threadedly connected to the internal threaded sleeve by a bolt passing through the through hole.

[0022] As a further solution of the utility model:

[0023] When the wedge protrusion is fully plugged into the matching opening, the top surface of the wedge protrusion and the top surface of the prefabricated cup opening base are at the same horizontal height.

[0024] When the prefabricated block is installed in the L-shaped sliding groove, the top bottom surface of the prefabricated block abuts against the top surface of the wedge protrusion.

[0025] As a further solution of the utility model:

[0026] The transverse movement limiting assembly includes a limiting groove formed on the inner side wall of the precast cup mouth foundation and a limiting block fixedly arranged on the wedge protrusion.

[0027] The limiting block cooperates with the limiting groove, and when the wedge protrusion is completely inserted into the mating port, the limiting block can be connected and assembled with the limiting groove.

[0028] Compared with the prior art, the beneficial effects of the utility model are as follows:

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0043] Please refer to Figures 1 - 9 , in the embodiment of the present invention, a connection node between a prefabricated precast concrete fence and a precast concrete fence foundation includes a precast wall panel 1 and a precast cup foundation 2, and the precast wall panel 1 and the precast cup foundation 2 are connected and assembled through a fitting component and a fastening component.

[0044] When the precast wall panel 1 is installed into the precast cup foundation 2, the fitting component can utilize the gravity of the precast wall panel 1 to make the connection between the two more stable.

[0045] The fastening component is used to keep the bottom of the precast wall panel 1 in contact with the bottom wall of the precast cup foundation 2.

[0046] A lateral movement limiting component is further provided between the precast wall panel 1 and the precast cup foundation 2, and the lateral movement limiting component can prevent the precast wall panel 1 and the precast cup foundation 2 from sliding out of place after installation.

[0047] In this solution, the chimeric component can utilize the gravity of the precast wall panel 1 when installing the precast wall panel 1 into the precast cup foundation 2, making their connection more stable; the fastening component can make the bottom of the precast wall panel 1 fit with the bottom wall of the precast cup foundation 2, and can prevent the precast wall panel 1 from being vertically disassembled from the precast cup foundation 2; the lateral movement limiting component can prevent the precast wall panel 1 and the precast cup foundation 2 from sliding horizontally after installation.

[0048] In this application, multiple precast cup foundations 2 can be arranged according to the planned scheme first, and then the multiple precast cup foundations 2 are pre-fixed. Since the mass of the precast cup foundation 2 is small, when it is found that a certain precast cup foundation 2 is misaligned or tilted, it is easier to correct it, avoiding the cumbersome adjustment of the precast wall panel 1, reducing the labor intensity and shortening the construction period.

[0049] As a further solution of the utility model, the chimeric component includes a wedge protrusion 3 integrally provided on the outer side of the lower part of the precast wall panel 1 and a mating opening 4 formed on the inner walls of both sides of the precast cup foundation 2.

[0050] The mating opening 4 is opened along the direction of the inner side wall of the precast cup foundation 2, and the wedge protrusion 3 is adapted to the mating opening 4.

[0051] The wedge protrusion 3 on the precast wall panel 1 is inserted into the mating opening 4. The surface of the wedge protrusion 3 close to the inner side wall of the precast cup foundation 2 is an inclined surface and is parallel to the inner side wall of the precast cup foundation 2.

[0052] The mating opening 4 is opened along the direction of the inner side wall of the precast cup foundation 2.

[0053] During the insertion process of the wedge protrusion 3 into the mating opening 4, under the gravity of the precast wall panel 1, the wedge protrusion 3 will be closely attached to the mating opening 4, so that the precast wall panel 1 and the precast cup foundation 2 are pre-assembled.

[0054] In this embodiment, since the surface of the wedge protrusion 3 close to the inner side wall of the precast cup foundation 2 is an inclined surface and is parallel to the inner side wall of the precast cup foundation 2; and the mating opening 4 is also opened along the direction of the inner side wall of the precast cup foundation 2; therefore, when the wedge protrusion 3 is inserted into the mating opening 4, under the gravity of the precast wall panel 1, the wedge protrusion 3 can be closely attached to the mating opening 4, realizing the pre-assembly of the precast wall panel 1 and the precast cup foundation 2.

[0055] Such as Figure 7 shown, the shapes of the wedge protrusion 3 and the mating opening 4 are set to facilitate insertion, do not require complete alignment, and have a guiding effect during the insertion process.

[0056] As a further solution of the utility model, the fastening assembly includes an L-shaped slide groove 5 opened at the top edge of the prefabricated cup mouth base 2 along the length direction of the prefabricated cup mouth base 2 and a detachable prefabricated block 6 arranged in the L-shaped slide groove 5.

[0057] An internal threaded sleeve 9 is embedded on the prefabricated cup mouth base 2 and located on one side of the L-shaped slide groove 5. A through hole 601 corresponding to the internal threaded sleeve 9 is penetrated on the prefabricated block 6, and a bolt can be passed through the through hole 601 to be threadedly connected to the internal threaded sleeve 9.

[0058] When the wedge protrusion 3 is fully inserted into the matching opening 4, the top surface of the wedge protrusion 3 and the top surface of the prefabricated cup opening base 2 are at the same horizontal height.

[0059] When the prefabricated block 6 is installed in the L-shaped sliding groove 5 , the top bottom surface of the prefabricated block 6 abuts against the top surface of the wedge protrusion 3 .

[0060] In this embodiment, when in use, the wedge protrusion 3 is first fully inserted into the matching opening 4, so that the prefabricated wall panel 1 and the prefabricated cup-mouth foundation 2 are pre-assembled. At this time, the top surface of the wedge protrusion 3 and the top surface of the prefabricated cup-mouth foundation 2 are at the same horizontal height, and then the prefabricated block 6 is horizontally slid and installed in the L-shaped slide groove 5. At this time, the top bottom surface of the prefabricated block 6 will abut against the top surface of the wedge protrusion 3, thereby limiting the vertical movement of the wedge protrusion 3, that is, the wedge protrusion 3 cannot be moved vertically out of the matching opening 4.

[0061] When the prefabricated block 6 is installed in the L-shaped slide groove 5, the through hole 601 is aligned with the internal threaded sleeve 9, and then a bolt is passed through the through hole 601 to threadably connect with the internal threaded sleeve 9, so that the prefabricated block 6 is fixed in the L-shaped slide groove 5 and cannot move, thereby playing a reinforcement role.

[0062] As a further solution of the utility model, the transverse limit assembly includes a limit groove 7 provided on the inner wall of the prefabricated cup mouth base 2 and a limit block 8 fixedly arranged on the wedge protrusion 3 .

[0063] The limiting block 8 and the limiting groove 7 cooperate with each other, and when the wedge protrusion 3 and the matching opening 4 are fully inserted, the limiting block 8 can be connected and assembled with the limiting groove 7.

[0064] In this embodiment, during installation, the limit block 8 on the wedge protrusion 3 is first roughly aligned with the limit groove 7 on the inner wall of the prefabricated cup-mouth foundation 2, and then the wedge protrusion 3 is inserted into the matching opening 4. During this process, the limit block 8 will also be inserted into the limit groove 7. Due to the interaction between the limit block 8 and the limit groove 7, the wedge protrusion 3 and the prefabricated cup-mouth foundation 2 cannot slide horizontally relative to each other, that is, the prefabricated wall panel 1 is horizontally restricted on the prefabricated cup-mouth foundation 2.
