Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, and in particular to an adjustable angle prefabricated steel structure connection node. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. When steel structures are used, they need to be connected by structural nodes. Structural nodes are one of the main elements of a building structure system. Generally speaking, the materials are limited by the maximum size of production or transportation, so the component that connects two or more fixed bodies is called a structural node. At the same time, because there is a wide selection of node types, sometimes special structural nodes are deliberately designed to increase structural toughness or reduce internal forces.

[0003] The existing device uses an arc-shaped connecting groove on the support plate to adjust the angle of the beam connection node. However, in actual operation, the existing device does not have a structure to indicate the angle of the beam connection node, which requires multiple adjustments to the position of the beam connection node when rotating it, making it inconvenient to operate. At the same time, the existing device cannot limit the beam connection node after it is rotated to the appropriate angle. Therefore, even if the beam connection node is adjusted to the appropriate angle, it is easy for it to rotate horizontally during the subsequent fixing process, resulting in installation accuracy deviation and affecting the overall stability and safety of the steel structure. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an adjustable angle prefabricated steel structure connection node, which solves the problems of existing steel structure connection nodes lacking angle indication and effective limiting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable-angle prefabricated steel structure connection node includes a support column, a pair of support plates vertically fixed to one side of the support column and symmetrically arranged vertically, a beam connection node inserted between the two support plates, a positioning pin vertically passing through the two support plates and the beam connection node, and an angle indicating component located between the positioning pin and the beam connection node; the beam connection node has several pairs of positioning holes spaced apart on both sides of the positioning pin, and several pairs of arc-shaped connecting grooves corresponding one-to-one with the positioning holes are passed through the two support plates; the positioning pin... A limiting groove is symmetrically opened on one side of the middle of the outer wall; the angle indicating component includes a C-shaped elastic limiting ring that is detachably sleeved on the outer side of the middle of the positioning pin and whose two ends are respectively locked in the corresponding limiting groove, a pair of plug rods that are detachably inserted into the two ends of the C-shaped elastic limiting ring, a mounting plate fixed between the two plug rods, and an indicator rod that is vertically fixed to the bottom center of the mounting plate; the lower inner surface of the crossbeam connecting node has several insertion holes that are adapted to the indicator rod around the center of the positioning pin; the lower inner surface of the crossbeam connecting node has angle indicating lines located outside the multiple insertion holes.

[0007] Even better, each support plate has a large rib between its outer side and the support column.

[0008] Even better, small ribs are provided between the inner side of each support plate and the support column.

[0009] Even better, shock-absorbing pads are provided between the inner side of each support plate and the connection node of the crossbeam.

[0010] This utility model has the following beneficial effects:

[0011] 1. This device uses the indicator rod of the angle indicator component to cooperate with the angle indicator line of the crossbeam connection node, so that the operator can obtain the angle information of the crossbeam connection node in real time and intuitively, without the need for repeated measurement and adjustment, greatly reducing the number of adjustments, shortening the installation time, and improving the convenience and efficiency of operation.

[0012] 2. Before fixing the crossbeam connection node, this device can temporarily limit the movement by inserting the indicator rod of the angle indicator component into the socket, thereby minimizing the horizontal rotation of the crossbeam connection node during the fixing process, ensuring installation accuracy, and improving the overall stability of the steel structure.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] An adjustable-angle prefabricated steel structure connection node includes a support column 1, a pair of support plates 2 vertically fixed to one side of the support column 1 and symmetrically arranged vertically, a crossbeam connection node 3 inserted between the two support plates 2, a positioning pin 4 vertically passing between the two support plates 2 and the crossbeam connection node, and an angle indicating component 5 disposed between the positioning pin 4 and the crossbeam connection node 3; the crossbeam connection node 3 has several pairs of positioning holes 31 spaced apart on both sides of the positioning pin 4, and several pairs of arc-shaped connecting grooves 21 corresponding one-to-one with the positioning holes 31 are opened through both support plates 2; the middle of the outer wall of the positioning pin 4... The limiting grooves 41 are symmetrically provided on both sides; the angle indicating component 5 includes a C-shaped elastic limiting ring 51 that is detachably sleeved on the outer side of the middle part of the positioning pin 4 and whose two ends are respectively locked in the corresponding limiting grooves 41, a pair of insert rods 52 that are detachably inserted on both ends of the C-shaped elastic limiting rings 51, a mounting plate 53 fixed between the two insert rods 52, and an indicator rod 54 that is vertically fixed at the bottom center of the mounting plate 53; the lower inner surface of the crossbeam connecting node 3 is provided with several insertion holes 32 that are adapted to the indicator rods 54 around the center of the positioning pin 4; the lower inner surface of the crossbeam connecting node 3 is provided with angle indicating lines 33 outside the multiple insertion holes 32.

[0020] By cooperating with the angle indicator rod 54 of the angle indicator component 5 and the angle indicator line 33 of the crossbeam connection node 3, the operator can obtain the angle information of the crossbeam connection node 3 in real time and intuitively, without the need for repeated measurement and adjustment, greatly reducing the number of adjustments, shortening the installation time, and improving the convenience and efficiency of operation; before fixing the crossbeam connection node 3, the indicator rod 54 of the angle indicator component 5 can be inserted into the socket 32 ​​to achieve temporary limiting, thereby minimizing the horizontal rotation of the crossbeam connection node 3 during the fixing process, ensuring installation accuracy, and improving the overall stability of the steel structure; any two adjacent sockets 32 can intersect or be separated.

[0021] As a possible implementation of this solution, preferably, each support plate 2 has a large rib plate 6 between its outer side and the support column 1; each support plate 2 has a small rib plate 7 between its inner side and the support column 1; the large rib plate 6 and the small rib plate 7 provided between the support plate 2 and the support column 1 significantly enhance the deformation resistance and load-bearing strength of the joint.

[0022] As a possible implementation of this solution, preferably, a shock-absorbing rubber pad 8 is provided between the inner side of each support plate 2 and the crossbeam connection node 3; the shock-absorbing rubber pad 8 can buffer vibration impact, reduce metal wear, reduce the wear rate of the node, and extend its service life.

[0023] The working principle of this device is as follows:

[0024] First, the crossbeam connecting node 3 is inserted between the two support plates 2, so that the mounting hole of the positioning pin of the crossbeam connecting node 3 is aligned with the mounting hole of the positioning pin of the support plate 2; the positioning pin 4 is inserted from the mounting hole of the upper support plate 2, and passes through the crossbeam connecting node 3 and the lower support plate 2 in sequence to complete the rotational connection.

[0025] Subsequently, the C-type elastic limiting ring 51 is fitted into the limiting groove 41 of the positioning pin 4 to ensure that both ends are locked; the insert rod 52 is inserted into the reserved holes at both ends of the C-type elastic limiting ring 51, and then the mounting plate 53 is welded between the two insert rods 52. The indicator rod 54 is welded to the bottom center of the mounting plate 53 to ensure that the indicator rod 54 is vertically downward and the lower end is inserted into the corresponding angle insertion hole 32 of the crossbeam connection node 3.

[0026] Finally, pass the fastening bolts through the arc-shaped connecting groove 21 of the support plate 2 and screw them into the positioning holes 31 corresponding to the beam connecting node 3. Tighten the bolts to achieve the limiting and fixing of the beam connecting node 3. Finally, connect the external steel beam to both ends of the beam connecting node 3 through the flange to complete the overall assembly.
