Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a steel structure assembled wall panel node. Background Technique

[0002] An assembled building refers to transferring a large amount of on-site operation work in the traditional construction method to the factory. Building components and fittings, such as floor slabs, wall panels, stairs, balconies, etc., are processed and manufactured in the factory and transported to the construction site, and assembled and installed on-site through reliable connection methods. Among them, the steel structure assembled wall panel node is an important part of connecting the steel structure assembled wall panel. These nodes play a connecting role between wall panels or between wall panels and other structural components, and bear the transfer and distribution of structural loads.

[0003] When the traditional wall panel node is spliced with the wall panel, the wall panel is directly inserted into the inner side of the wall panel node. In the actual use process of the existing snap-on installation, there will still be a situation where the wall panel moves relative to the wall panel node, thereby reducing the connection stability between the wall panel node and the wall panel. And during the long-term wear and consumption process, this situation will become more serious. Therefore, there is an urgent need for an assembled wall panel node with stable connection. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above problems existing in the prior art, and proposes a steel structure assembled wall panel node, which realizes the connection stability between the wall panel and the wall panel node through the structural design and cooperation of the L-shaped connection seat, the clamping block and the assembled wall panel.

[0005] The technical solution of the utility model is as follows:

[0007] The L-shaped connection seat includes a vertical plate and a bottom plate that are perpendicular to each other. At least one side plate is connected between the bottom plate and the vertical plate, and a limiting wedge block is arranged on the inner wall of the side plate; an installation groove is opened on the vertical plate, and a first screw hole is opened on its upper end surface, and the first screw hole is communicated with the installation groove below it;

[0008] Clamping grooves matching the limiting wedge blocks are opened on both sides of the assembled wall panel, and a limiting groove is opened on the surface of the assembled wall panel in contact with the vertical plate;

[0009] The clamping block connects the L-shaped connection seat and the assembled wall panel through the installation groove. A guiding groove corresponding to the first screw hole is opened on the upper end surface of the clamping block, and the part of the clamping block extending into the L-shaped connection seat is an I-shaped structure matching the limiting groove.

[0010] Further, a plurality of second screw holes are penetratingly provided on the side plate, and connecting holes consistent with the positions and quantities of the second screw holes are provided on the side surface of the prefabricated wall panel. A fastener is used to connect the L-shaped connecting seat and the prefabricated wall panel through the second screw holes and the connecting holes.

[0011] Further, the fastener is a bolt, and a bushing is installed in the connecting hole. The bushing is sleeved on the bolt, and the bolt and the bushing are in threaded connection.

[0012] Further, the first screw hole is provided at the center of the upper end surface of the vertical plate, and the first screw hole extends downward to communicate with the installation groove and further with the guiding groove.

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "inside", "outside", "above", "below", etc. is based on the positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0024] As Figure 1 and Figure 2 shown, the present utility model provides a steel structure assembled wall panel node, including an L-shaped connection seat 2, a clamping block 5, and an assembled wall panel 1 that is clamped and connected to the L-shaped connection seat 2. It further includes an installation base 3, and the L-shaped connection seat 2 is arranged on the installation base 3.

[0025] The L-shaped connection seat 2 includes a vertical plate and a bottom plate that are perpendicular to each other, and the bottom plate is fixedly connected to the installation base 3. At least one side plate is connected between the bottom plate and the vertical plate. In this embodiment, the number of side plates is two. As Figure 3 can be seen, the side plates are installed at two side positions of the vertical plate and the bottom plate, and the two side plates are arranged oppositely, jointly forming a groove for installing the assembled wall panel 1 with the bottom plate and the vertical plate.

[0026] Limiting wedges 9 are arranged on the inner walls of the two side plates. Correspondingly, clamping grooves 101 that match the limiting wedges 9 are provided on the two sides of the assembled wall panel 1. When the assembled wall panel 1 is placed into the groove, the clamping grooves 101 are clamped and connected to the limiting wedges 9. The corresponding clamping of the limiting wedges 9 and the clamping grooves 101 can provide a basic anti-displacement function and improve the tightness of the connection between the two.

[0027] Further, a plurality of through screw holes two 21 are provided on the side plates on both sides. Correspondingly, two side surfaces of the assembled wall panel 1 are provided with connection holes 102 that are the same in position and quantity as the screw holes two 21. In this embodiment, two screw holes two 21 are arranged vertically. The purpose of the design of the holes here is to further stabilize the connection between the L-shaped connection seat 2 and the assembled wall panel 1. In the specific application process, their positions and quantities can be designed according to actual needs, so long as the purpose can be achieved. A fastener, such as the bolt two 4 used in this embodiment, is used to connect the screw holes two 21 and the connection holes 102, and then connect the L-shaped connection seat 2 and the assembled wall panel 1. During the actual installation process, the bolt two 4 enters from the screw hole two 21 on one side plate of the L-shaped connection seat 2, passes through the assembled wall panel 1, and exits from the screw hole two 21 on the other side plate, so as to fixedly connect the L-shaped connection seat 2 and the assembled wall panel 1.

[0028] It should be explained that a bushing 8 is sleeved and installed outside the bolt two 4 here. The bushing 8 is snap-fitted and installed in the connection hole 102 opened inside the assembled wall panel 1. Through the setting of the bushing 8, the tightness of the connection between the bolt two 4 and the connection hole 102 can be improved, and the stability between the two can be ensured. During the actual application process, the bushing 8 is sleeved in the connection hole 102, and the connection between the bolt two 4 and the bushing 8 is a threaded connection.

[0029] An installation groove 10 is provided on the vertical plate of the L-shaped connection seat 2, and a snap block 5 is installed in the installation groove 10 in a limited way. As Figure 4 shown, the snap block 5 connects the L-shaped connection seat 2 and the assembled wall panel 1 through the installation groove 10.

[0030] On the surface of the assembled wall panel 1 in contact with the vertical plate, a limit groove 103 that penetrates at the bottom is provided. The part of the snap block 5 extending into the groove of the L-shaped connection seat 2 is an I-shaped structure that matches the limit groove 103. The middle structure of this I-shaped structure is the same size as the limit groove 103, and the limit groove 103 can be snap-fitted at the I-shaped structure part, so as to realize the clamping connection between one end of the snap block 5 and the assembled wall panel 1.

[0031] A screw hole one 7 is provided at the middle position of the upper end surface of the vertical plate of the L-shaped connection seat 2. The screw hole one 7 extends downward and communicates with the installation groove 10 below it. In the middle of the upper end surface of the snap block 5 arranged in the installation groove 10, a guide groove 51 corresponding to the screw hole one 7 is also provided. Therefore, the screw hole one 7 and the guide groove 51 are also communicated. The guide groove 51 is inclined toward the side of the assembled wall panel 1.

[0032] A bolt one 6 is arranged in the screw hole one 7. A conical head 61 is provided at the lower end of the bolt one 6, and the conical head 61 extends into the inside of the snap block 5, that is, into the guide groove 51. The bolt one 6 is used to connect the L-shaped connection seat 2 and the snap block 5 through the screw hole one 7 and the guide groove 51.

[0033] The present utility model also provides an installation process of a node of a steel structure assembled wall panel 1, which is specifically as follows:

[0034] In this specific embodiment, the whole node is installed on the designated installation surface through the installation base 3, and the clamping block 5 is inserted into the installation groove 10, and the first bolt 6 is screwed into the first screw hole 7 through the thread to limit the clamping block 5. At the same time, the assembled wall panel 1 is inserted and installed into the L-shaped connecting seat 2. The clamping groove 101 provided on the assembled wall panel 1 is correspondingly clamped with the limiting wedge block 9. During the insertion process, the limiting groove 103 is clamped with the clamping block 5, and the clamping block 5 is installed inside the limiting groove 103. When the assembled wall panel 1 is completely placed on the L-shaped connecting seat 2, its connecting hole 102 coincides with the second screw hole 21. At this time, the second bolt 4 is sleeved with the bushing 8 to connect the holes. The setting of the bushing 8 can ensure the tightness of the connection between the two. At the same time, the first bolt 6 is rotated, and the first bolt 6 descends and presses the guiding groove 51 opened in the middle of the clamping block 5 through the conical head 61. Since the guiding groove 51 is inclined, during the continuous downward pressing of the conical head 61, the clamping block 5 moves slightly outwards to further lock the assembled wall panel 1.

[0035] The above description is only the preferred embodiment of the present utility model and is not a limitation to the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some of the technical features. Any modification, equivalent replacement, modification, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
