Description

Technical Field

[0001] The utility model relates to the technical field of building installation structures, in particular to a modular steel structure connection structure. Background Art

[0002] Steel structure is one of the main types of building structures, especially in mobile homes, temporary buildings and factory frame structures. Steel structure is often used, and almost no construction waste is generated when steel structure buildings are demolished, which makes steel structure widely used. However, the joints of steel structure are crucial, and in modular buildings, steel structure is usually assembled on site using bolts and partial welding.

[0003] In the Chinese utility model patent with publication number CN219732292U, a modular steel structure connection structure mainly includes columns and cross steels. The support frame is fixed on the column by multiple fixing blocks, and then one end of the cross steel is fixed by clamping and rubber pads. However, in this technology, the cross steel is installed on the column by the clamping parts on the support frame, and the end is also arranged inside the support frame. The main fixing role between the support frame and the column is played by multiple fixing blocks, wherein the multiple fixing blocks are symmetrically distributed in a rectangular array, each fixing block is distributed in a straight line downward with the column, and cannot interact with the fixing blocks on other surfaces of the column. This results in the force generated by the cross steel, and only the fixed block on one side of the column generates force, which can easily cause the fixed block to deform and the column connection to be damaged, making the connection between the cross steel and the column unstable. For this reason, we provide a modular steel structure connection structure to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-8As shown, the utility model provides a technical solution: a modular steel structure connection structure, including a column 1, support platforms 3 are arranged around the column 1, and adjacent support platforms 3 are connected to each other, so that multiple support platforms 3 construct an installation area distributed around the column 1 on the column 1, and the installation area formed by the support platforms 3 is connected to a cross steel 2, and an installation component 6 is arranged between the cross steel 2 and the support platform 3 and the column 1, and the installation component 6 is used to form the column 1, the support platform 3 under the cross steel 2 and the corresponding adjacent support platform 3 into a whole, so as to reduce the pressure on a single side of the column 1.

The cross steel 2, the column 1 and the multiple connected and fixed modules are constituted as a whole, so that the force generated by one of the cross steels 2 acts on the connection and fixing parts on other sides through the installation component 6 and the support platform 3, rather than the fixed connection on one side of the column 1 that plays a bearing role, thereby reducing the pressure on the single-side connection and improving its connection stability.

[0029] A plurality of positioning blocks 13 are arranged on the column 1. The positioning blocks 13 are T-shaped. The upper surfaces of the positioning blocks 13 are respectively in contact with the corresponding support platform 3 and the bottom of the fourth bolt 10, thereby preventing the fourth bolt 10 from falling off.

An indicator mark is provided at the end of the fifth bolt 11, and the indicator mark matches the axis of the through hole, so that the indicator mark can be observed outside the column 1 to determine the direction of the through hole, thereby facilitating assembly.

[0031] A plurality of semicircular holes are provided on the support platform 3 and the protrusion 4, and the two support platforms 3 are connected to each other to form a circular hole that passes through from top to bottom; a positioning hole opposite to the circular hole is provided on the connecting arm 601; the protective mechanism includes a T-shaped baffle 14, the bottom of the baffle 14 is in contact with the connecting arm 601, a connecting hole that passes through from top to bottom is provided on the baffle 14, a limiting cylinder 15 is provided in the baffle 14, the limiting cylinder 15 passes through the connecting hole, the positioning hole and the circular hole from top to bottom in sequence, and an anti-falling component is also provided on the top of the limiting cylinder 15, so that the limiting cylinder 15 prevents the fifth bolt 11 from falling off and prevents the adjacent support platforms 3 from separating through the baffle 14; the T-shaped top of the baffle 14 contacts the bottom of the anti-falling component, and the bottom contacts the connecting arm 601, which plays the effect of supporting up and down to prevent the baffle 14 from shaking.

[0032] The anti-falling component includes a connecting plate 17, which is connected to the top of the cross steel 2 by a sixth bolt 12. One end of the connecting plate 17 is connected to the top of the limiting cylinder 15, and the other end symmetrically located on the connecting plate 17 is fixedly connected to the limiting rod 16. The bottom end of the limiting rod 16 passes through the limiting cylinder 15 on another connecting plate 17, so that multiple limiting rods 16, connecting plates 17 and limiting cylinders 15 form a closed ring, which plays a role in mutual restriction and positioning; an opening is provided at the edge of the top of the limiting cylinder 15, and the inner wall of the opening is in contact with the connection between the limiting rod 16 and the connecting plate 17, and the depth of the opening is the same as the thickness of the connecting plate 17, so that the upper surfaces of multiple connecting plates 17 overlap, thereby improving the stability between the connecting plates 17 and the connecting plates 17; at the same time, the bottom of the connecting plate 17 is in contact with the top of the baffle 14, so that it will not shake, and a thread can also be provided at the bottom end of the limiting rod 16, and it can be fixed by a nut to play a role of clamping up and down, and to play a role of pressing in the vertical direction, thereby further improving the effect of fixing the cross steel 2.

[0034] During installation, first weld multiple positioning blocks 13 to the column 1 to form a platform on the column 1, and then plug multiple support platforms 3 into each other through the protrusions 4 and the slots 5 to form a larger rectangular ring sleeved on the outside of the column 1, and then push the support platforms 3 in small increments in sequence or push multiple support platforms 3 toward the column 1 at the same time, and the protrusions 4 are fully inserted into the slots 5, so that the support platforms 3 fit on the column 1, and then move the support platforms 3 downward and place them on the positioning blocks 13, corresponding to the holes on the column 1, and then fix them on the column 1 through the third bolts 9, and then set the cross steel 2 on the support platform 3, and make one end of the cross steel 2 contact the surface of the column 1 Touch, and then move the installation component 6 along the channel between the limit block 18 and the cross steel 2 into the space between the cross steel 2 and the column 1, and then fix the cross steel 2, the support platform 3 and the installation component 6 by the first bolt 7.
