Description

Technical Field

[0001] This utility model relates to the field of frame accessory installation technology, and in particular to a prefabricated small frame node connector. Background Technology

[0002] In existing prefabricated frames, connectors are used at the joints of the frame nodes during installation. These connectors typically use high-strength bolts to connect beams and columns. In addition, the existing frame node installation process is too simplistic. Existing beam-column nodes include a node with one column and four beams. The steel column is installed first, and then each steel beam is installed individually. During the installation process, the steel column can only be installed one by one, and sometimes welding is required for connection. This not only fails to achieve rapid installation, but also results in relatively high installation costs. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a prefabricated small frame node connector, which uses the pin as a connector for multiple beams and columns. The node connector is designed as a separate component, requiring only bolt connection. After the lower beam and column structure is installed, the upper structure can be installed at once, which will greatly reduce repeated installation and labor costs.

[0004] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions:

[0005] A prefabricated small frame node connector includes a pin, which includes a fixing plate, a first steel column, and a reinforcing rib. The fixing plate has a cross-shaped structure, and a reinforcing rib is fixedly connected to the inner side of each of the four right-angled sides of the fixing plate. Multiple first steel columns are fixedly connected to the upper and lower surfaces of the middle position of the fixing plate. The multiple first steel columns on each side of the fixing plate are spaced a certain distance apart to form a cross-shaped middle seam. Each first steel column is fitted with a second steel column.

[0006] Furthermore, the right-angled side of the fixing plate is provided with first screw holes that penetrate the fixing plate and are arranged in two parallel rows, and the number of first screw holes is several.

[0007] Furthermore, the second steel column is fixedly connected to the first beam on both sides of the end near the fixing plate and facing outward.

[0008] Furthermore, the two first beams located on the same second steel column are designed to be perpendicular to each other at 90 degrees, and are parallel to the right-angled sides of the adjacent fixed plates, respectively.

[0009] Furthermore, the surface of the first beam is provided with a number of second screw holes arranged in a line, and the number of second screw holes is several and they are distributed vertically and vertically corresponding to the first screw holes provided on the right-angle side of the fixing plate.

[0010] Furthermore, a connecting bar is fixedly connected to the lower surface of the first beam, and the side of the connecting bar closest to the second steel body is fixedly connected to the second steel column.

[0011] Furthermore, a second beam is provided on the side of the connecting rib away from the first beam. The second beam is arranged parallel to the first beam vertically, and the side of the second beam closer to the second steel body is fixedly connected to the second steel column.

[0012] Furthermore, the surface of the connecting rib is provided with a third screw hole through which the connecting rib can pass.

[0013] Furthermore, the first beams located on the upper and lower sides of the fixed plate are fixedly connected by bolts, and the bolts will pass through the first screw holes on the surface of the fixed plate during the connection of the first beams.

[0014] Furthermore, the relatively positively positioned reinforcing ribs are fixedly connected by bolts passing through the third screw hole.

[0015] Compared with the prior art, this utility model has at least the following advantages and beneficial effects:

[0016] 1. The small frame connector of this utility model adopts a separate component structure, namely a pin. After the steel column structure on the lower side of the pin is installed, the pin can be placed directly on the upper surface of the lower steel column. The four first steel columns on each side of the pin fixing plate are spaced a certain distance apart to form a cross-shaped middle seam. At this time, several second steel column assemblies composed of the first beam, reinforcing rib, second steel column and second beam can be assembled and inserted into the outer side of the first steel column on the upper surface of the corresponding fixing plate at one time. Finally, the connection of the corresponding structure is achieved with bolts, which greatly reduces repeated installation and labor costs.

[0017] 2. The steel columns and beams on both sides of the pin can be connected with only bolts, which perfectly avoids the defects caused by welding in the existing technology.

[0018] Advantages of the present invention in additional aspects will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention.

[0027] Where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0028] Example 1:

[0029] like Figure 1 As shown, this embodiment provides a prefabricated small frame node connector, including a pin, which includes a fixing plate 1, a first steel column 2, and a reinforcing rib 3. The fixing plate 1 adopts a cross-shaped structure. A reinforcing rib 3 is fixedly connected to the inner side of each of the four right-angled sides of the fixing plate. Multiple first steel columns 2 are fixedly connected to the upper and lower surfaces of the middle position of the fixing plate. The multiple first steel columns on each side of the fixing plate are spaced at a certain distance to form a cross-shaped middle seam. Each first steel column is fitted with a second steel column 4. When the second steel column is fitted onto the outside of the first steel column, it will fill the cross-shaped middle seam. The right-angled sides of the fixing plate are provided with first screw holes 5 that penetrate the fixing plate and are arranged in two parallel rows.

[0030] In this embodiment, four first steel columns 2 are fixedly connected to the upper and lower surfaces of the middle position of the fixed plate. The number of first steel columns 2 can be changed according to the actual situation.

[0031] In this embodiment, the length of the right-angled side of the fixing plate, i.e. the cross-shaped structure, will vary depending on the position of the small frame node. This will also change the shape and size of the reinforcing ribs on the inner side of the four right-angled sides of the fixing plate, and the position and number of the first screw holes on the right-angled sides of the fixing plate will also change.

[0032] like Figure 2 As shown, if the small frame node is located inside the entire assembly frame, the four right-angled sides of the fixing plate 1 are of the same length, the reinforcing rib plate 3 is a vertical triangle, and the four right-angled sides of the fixing plate are provided with first screw holes 5 that penetrate the fixing plate and are arranged in two parallel rows, with a certain number of first screw holes.

[0033] like Figure 3 As shown, if the small frame node is located on the outside of the entire assembly frame, the four right-angled sides of the fixing plate 1 adopt a length combination pattern of three long and one short. The three long right-angled sides of the fixing plate are provided with first screw holes 5 that penetrate the fixing plate and are arranged in two parallel rows. The short right-angled sides are not provided with first screw holes. The reinforcing rib plate 3 adopts a vertical triangle or trapezoidal structure at this time.

[0034] like Figure 1 and Figure 4 As shown, in this embodiment, the second steel column is fixedly connected to the first beam 6 on both sides of the end near the fixing plate and facing outward. The first beam 6 adopts a rectangular structure. The two first beams located on the same second steel column are designed to be perpendicular to each other at 90 degrees. The two first beams are respectively arranged parallel to the right angle side of the adjacent fixing plate.

[0035] To ensure the stability of the connection between the first beam and the fixing plate, this embodiment provides several second screw holes 7 arranged in a line on the surface of the first beam 6. The number of second screw holes is several and they are distributed vertically and vertically corresponding to the first screw holes 5 provided on the right-angle side of the fixing plate. Since the first beam is provided on both the upper and lower sides of the fixing plate, the first beams on the upper and lower sides of the fixing plate are fixedly connected by bolts. During the process of connecting the first beams, the bolts will pass through the first screw holes on the surface of the fixing plate, thus connecting the fixing plate and the first beams on its upper and lower sides.

[0036] To enhance the strength of the first beam and the second steel column, and considering the connection between the opposing first beams, this embodiment has a connecting rib 8 fixedly connected to the lower surface of the first beam. A second beam 9 is provided on the side of the connecting rib 8 away from the first beam. The side of the connecting rib 8 close to the second steel column is fixedly connected to the second steel column, and the side of the second beam close to the second steel column is fixedly connected to the second steel column. In this way, the connecting rib, the first beam, the second beam, and the second steel column will form a second steel column assembly. The second beam and the first beam are arranged parallel vertically and have the same length. In addition, a third screw hole 10 is provided on the surface of the connecting rib, penetrating the connecting rib. There are several third screw holes arranged in two parallel rows. The opposing reinforcing ribs can be directly fixedly connected by bolts passing through the third screw holes 10.

[0037] As described above and combined Figures 1 to 5 As shown, when it is necessary to connect steel columns and steel beams using pins, the bottom steel columns and beams are installed first, in a bottom-up manner. The specific steps are as follows:

[0038] Step one: First, the first beam, the reinforcing rib, and the second beam will be fixedly installed onto the second steel column according to the assembly requirements, and finally assembled into several second steel column assemblies.

[0039] Step 2: A set of lower structures includes four second steel column assemblies. Several sets of second steel columns of the lower structures are fitted onto the outer side of the first steel column on the lower surface of the corresponding fixing plate, and the corresponding reinforcing ribs are fixedly connected by bolts through the third screw holes of the lower structure.

[0040] Step 3: After the reinforcing ribs of the lower structure are fixedly connected, several sets of upper structures are directly fitted onto the outer side of the first steel column on the upper surface of the corresponding fixing plate (Note: the upper structure in this step is the same as the lower structure). After the upper structure is installed as a whole, the reinforcing ribs of the upper structure are fixedly connected by bolts through the third screw hole, and the fixing plate and the first beams on the upper and lower sides are connected by bolts through the first screw hole and the second screw hole.

[0041] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
