Description

Technical Field

[0001] The utility model belongs to the technical field of light steel structure houses, and particularly relates to a light steel house building connection structure. Background Art

[0002] Lightweight steel structures are primarily used in low-rise residential buildings that are not subject to heavy loads. These prefabricated and assembled low-rise and multi-story steel structures utilize lightweight H-section steel (welded or rolled; variable or uniform cross-section) to create a portal-shaped steel frame. C- and Z-shaped cold-formed thin-walled steel sections serve as purlins and wall beams. Corrugated steel sheets or lightweight sandwich panels serve as the roof and wall enclosures. High-strength bolts, standard bolts, self-tapping screws, and other fasteners, along with sealing materials, are used to assemble these structures. Lightweight steel structures are widely used in rural housing construction due to their excellent seismic and wind resistance, as well as their short construction period.

[0003] Existing rural light steel structure houses are often connected by welding, where the ends of the beams are welded to the surfaces of the columns. The welding points are only contact points, and the forces acting on the beams are all acted on the welding points. Although this method is convenient for construction, it is gradually replaced by bolt connections because welding is difficult to adjust. The bolt connection between the light steel beams and the columns often requires first bolting the connectors to the columns, and then connecting the connectors to the beams. During this process, workers mostly need to hold the connectors with one hand and install the bolts with the other hand. Workers are very likely to lose balance and fall off the scaffolding during the installation process, causing danger. Therefore, a light steel house building connection structure is needed to solve the above problems. Utility Model Content

[0004] In order to solve the above problems in the prior art, a light steel house building connection structure is proposed.

[0005] The technical solution of the utility model for solving the technical problem is: a light steel house building connection structure, including a column, a through hole is provided on the column, and a connecting piece is provided on the column; the connecting piece includes a connecting plate, a clamping column is provided on one side of the connecting plate, the clamping column extends into the through hole to enable the connecting piece to be rotatably connected to the column, and the side of the connecting plate is also connected to a limit plate, and a shear bolt hole is provided on the limit plate, and the shear bolt passes through the shear bolt hole to be connected to the column; the other side of the connecting plate is connected to the crossbeam.

[0010] Preferably, a pull plate is further provided on the side of the column, which is connected to a first clamping bolt, and two sets of second clamping bolts are provided on the corresponding top of the beam. The two ends of the cable are respectively fixed on the two second clamping bolts and the middle part of the cable passes through the first clamping bolt to form a tensioning structure.

[0012] Compared with the existing technology, the above technical solution has the following advantages or beneficial effects:

[0023] Example 1:

[0024] Please see the attached Figures 1-4In order to solve the problem that when installing the connector 2, a worker needs to use one hand to fix it and the other hand to install the bolts, which is inconvenient and unsafe, this embodiment proposes a light steel building connection structure, including a column 1, a through hole is provided on the column 1, and a connector 2 is provided on the column 1; the connector 2 includes a connecting plate 21, and a clamping column 22 is provided on one side of the connecting plate 21. The clamping column 22 extends into the through hole to enable the connector 2 to be rotatably connected to the column 1. The connecting plate 21 is also connected to a limit plate 23 on this side. The limit plate 23 has a shear bolt hole 26, and the shear bolt 3 passes through the shear bolt hole 26 to connect with the column 1. In this embodiment, the limit plate 23 is L-shaped, and the connecting plate 21 and the limit plate 23 are combined to form a U-shaped space. The U-shaped space can wrap the column 1 and enable the connector 2 to be clamped to the column 1; the other side of the connecting plate 21 is connected to the crossbeam 4.

[0025] When in use, just push the clamping post 22 into the through hole of the column 1. Figure 3 As shown, at this time, the connecting member 2 is ninety degrees away from the fixed position. At this time, it is rotated ninety degrees so that the limit plate 23 contacts the column 1. At this time, the relative position of the connecting member 2 and the column 1 can be determined, and the shear bolt 3 can be screwed in.

[0026] Example 2:

[0027] Continue to refer to the attached Figures 1-4 The other parts are the same as those in the first embodiment, except that: in this embodiment, a support block 24 is provided on the side where the connecting plate 21 connects to the crossbeam 4. Baffles 25 are connected to both sides of the support block 24. The support block 24 and baffles 25 form a connection space, and the end of the crossbeam 4 is placed in the connection space. The end of the crossbeam 4 is fixedly connected to a fixing plate 41, which is connected to the connecting plate 21 via connecting bolts 6.

[0028] In addition, in this embodiment, a diagonal brace 27 is provided at the bottom of the support plate. One end of the diagonal brace 27 is fixedly connected to the connecting plate 21. The other end of the diagonal brace 27 defines a diagonal brace bolt hole 28. The diagonal brace 27 bolt passes through the diagonal brace bolt hole 28 to connect the diagonal brace 27 to the crossbeam 4. The top of the diagonal brace 27 is located in the same plane as the top of the support block 24.

[0029] By providing the support plate and the diagonal brace 27 , the crossbeam 4 can be directly hoisted onto the support plate after the connector 2 is installed, and then the next step of installation and connection can be carried out without manual positioning, which makes installation convenient.

[0030] Example 3:

[0031] Continue to refer Figures 1-4In this embodiment, all other parts are identical to those of the second embodiment, with the difference being that a pull plate 7 is further provided on the side of the upright column 1. This pull plate 7 is connected to a first clamping bolt 8. Two sets of second clamping bolts 10 are provided on the top of the corresponding crossbeam 4. The ends of the cable 9 are fixed to the two second clamping bolts 10, and the middle portion of the cable 9 passes through the first clamping bolts 8 to form a tensioning structure. This is equivalent to hooking the middle portion of the cable 9 onto the first clamping bolt 8, thereby allowing the cable 9 to pull the crossbeam 4.

[0032] When connecting, you only need to put the two ends of the cable 9 on the two second clamping bolts 10 first, then hook the middle part of the cable 9 upward over the first clamping bolt 8, and then turn the nuts of the second clamping bolts 10 to continuously press the two ends of the cable 9 down to provide pre-tightening force.

[0033] Directions:

[0034] First, insert the clamping column 22 of the connecting part 2 into the through hole, rotate the connecting part 2 to make the limit plate 23 fit with the column 1, and screw on the shear bolt 3; then hoist the beam 4, place the end of the beam 4 into the connecting space, and screw in the connecting bolt 6 and the diagonal brace 27 bolts; finally, put the two ends of the cable 9 on the two second clamping bolts 10, and then hook the middle part of the cable 9 upward over the first clamping bolt 8, and then rotate the nut of the second clamping bolt 10 to continuously press the two ends of the cable 9 down to provide pre-tightening force to complete the installation of the beam 4.

[0035] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the utility model.
