Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a rotatable and lockable support column splicing node. Background Technology

[0002] Temporary supports are temporary structures used to support the superstructure during steel structure installation, before the superstructure has formed an integral structure. Currently, lattice-type temporary supports are the most widely used in the installation of large-span spatial steel structures. Lattice-type temporary supports can be widely used in various large public buildings. However, the columns of lattice-type temporary supports are usually connected by flanges, which is inconvenient for installation and dismantling. During installation, bolts are easily loosened. In addition to the main components, bolts and other loose parts are generated during dismantling. As the lattice-type temporary supports are transported to other projects for reuse, these loose parts are not easy to store and are easily lost, causing inconvenience to construction applications. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a rotatable and lockable support column splicing node. All components used can be disassembled and reused, and there are no loose parts such as bolts during use, which facilitates construction.

[0004] To achieve the above technical effects, this utility model provides a rotatable and lockable support column splicing node, which includes:

[0005] An upper column and a lower column are spliced ​​together end to end in a vertical direction. A first pin is fixedly connected to the upper column at a position relatively close to the bottom, and a second pin is fixedly connected to the lower column at a position relatively close to the top.

[0006] A sleeve for splicing the upper and lower columns end to end. The first end of the sleeve has a first through hole at the position corresponding to the first pin for sliding insertion of the first pin, and the second end has a second through hole at the position corresponding to the second pin for sliding insertion of the second pin. The second end of the sleeve has a vertical channel at the bottom of the second through hole. The vertical channel communicates with the second through hole and forms a movable space for the second pin to slide vertically and fall into the second through hole when the upper and lower columns are spliced ​​end to end.

[0007] An elastic locking element is fixedly installed on the sleeve. The elastic locking element has a locking tongue that is elastically installed inside to pop out into the second through hole to abut against the second pin, thereby locking the upper column and the lower column after they are spliced ​​together end to end.

[0008] Preferably, both the first through hole and the second through hole are elongated holes opened in the horizontal direction, and each of the two elongated holes has a sliding space for the corresponding first pin or second pin to slide in the horizontal direction.

[0009] Preferably, the two elongated holes are of the same length and their edges are vertically aligned.

[0010] Preferably, when the elastic locking member is in the locked state, the locking tongue pops out in the second through hole and abuts against the second pin; when in the reset state, the locking tongue retracts so that the second pin can slide in the second through hole until it disengages from the second through hole.

[0011] Preferably, the length of the latch is greater than the width of the second through hole.

[0012] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0013] 1) By inserting the sleeve connected to the upper column into the lower column with the second pin and tightening it in place, the second pin pushes the locking tongue of the elastic locking member into the device. Then, by rotating the sleeve, the second pin moves to the end of the second through hole. At this time, the locking tongue of the elastic locking member pops out and locks the sleeve so that it can no longer rotate, thereby completing the installation of the node.

[0014] 2) By manually pulling back and fixing the locking tongue of the elastic locking member, rotating the sleeve to move the second pin to the vertical channel, and pulling out the sleeve and the upper column connected to the sleeve, the disassembly of the node can be completed.

[0015] 3) All components are detachable and reusable, and there are no loose parts such as bolts during use. The structure is reasonable, easy to use, and quick to construct, meeting the bearing capacity requirements of temporary supports for lattice steel structures. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 3 As shown, this utility model embodiment provides a rotatable and lockable support column splicing node, including an upper column 1, a lower column 2, a sleeve 2, and an elastic locking member 6. The upper column 1 and the lower column 2 are spliced ​​end to end in the vertical direction. A first pin 51 is fixedly connected to the upper column 1 at a position relatively close to the bottom, and a second pin 52 is fixedly connected to the lower column 2 at a position relatively close to the top. The sleeve 3 is used to splice the upper column 1 and the lower column 2 end to end. The first end of the sleeve 3 has a first through hole 41 at the position corresponding to the first pin 51 for the first pin 51 to slide into, and the second end has a second through hole 42 at the position corresponding to the second pin 52 for the second pin 52 to slide into. The second end of the sleeve has a vertical channel 43 at the bottom of the second through hole 42. The vertical channel 43 communicates with the second through hole 42 and forms an active space for the second pin 52 to slide vertically into the second through hole 42 when the upper column 1 and the lower column 2 are spliced ​​end to end.

[0024] Furthermore, the elastic locking member 6 is fixedly installed on the sleeve 3. The elastic locking member 6 is elastically installed with a locking tongue 61 for popping out into the second through hole 42 to abut against the second pin 52, thereby locking the upper column 1 and the lower column 2 after they are spliced ​​together end to end.

[0025] Please see Figure 2 As shown, in this embodiment, both the first through hole 41 and the second through hole 42 are elongated oval holes opened in the horizontal direction, and each of the two elongated oval holes has a sliding space formed for the corresponding first pin 51 or second pin 52 to slide in the horizontal direction. Preferably, the two elongated oval holes have the same length and their edges are vertically aligned.

[0026] Please see Figure 1 and Figure 3 As shown, when the elastic locking member 6 is in the locked state, the locking tongue 61 pops out within the second through hole 42 and abuts against the second pin 52, thereby locking the sleeve 3. In the reset state, the locking tongue 6 retracts to allow the second pin 52 to slide within the second through hole 42 until it disengages from the second through hole 42. Preferably, in this embodiment, the length of the locking tongue 61 is greater than the width of the second through hole 42.

[0027] When using it, it is first processed in the factory, such as Figure 2 The sleeve 3 shown is fitted with an elastic locking element 6. The elastic locking element 6 can be a device similar to a door lock (a latch 61 that can be freely extended and retracted controlled by an internal spring). The upper column 1 is connected to the sleeve 3. It should be noted that the first pin 51 on the upper column 1 needs to be inserted into the first through hole 41 after the sleeve 3 is fitted in. A welding rod is used to extend from the end of the upper column 1 to the inside, thereby welding and fixing the first pin to the upper column 1 (the second pin 52 is directly welded to the lower column 2). When splicing the upper and lower columns, the sleeve 3 connected to the upper column 1 is fitted into the sleeve with the second pin. The upper column 2 of shaft 52 is pressed into place (when fitting, the second pin 52 is aligned with the vertical channel 43 on the sleeve 3). At this time, the locking tongue 61 of the elastic locking member 6 is in the reset state (i.e., located inside the elastic locking member 6). Rotating the sleeve 3 causes the second pin 52 to move to the end of the second through hole 42. At this time, the locking tongue 61 of the elastic locking member 6 pops out into the second through hole 42 and abuts against the second pin 52, thereby locking the sleeve 3 so that it can no longer rotate, completing the installation of the column splicing node. The pressure of the support column can be transmitted through the planing and tightening of the ends of the upper and lower columns, and the tension sleeve and pin are transmitted.

[0028] When disassembly is required, manually pull the locking tongue 61 of the elastic locking member 6 back into the elastic locking member 6 and fix it (i.e., in the reset state), rotate the sleeve 3 to make the second pin 52 slide along the second through hole 42 to the vertical channel 43, and then pull out the sleeve 3 and the upper column 1 connected to the sleeve 3 to complete the disassembly of the node.

[0029] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
