Description
Technical Field
[0001] The utility model relates to the field of connection of prefabricated steel components, in particular to a prefabricated steel component with stable installation. Background Technique
[0002] Steel components refer to steel structure composite components that can bear and transfer loads, which are connected by steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-beams through cold bending or welding. Because of their light self-weight and simple construction, they are widely used in large factories, bridges, stadiums, super high-rise buildings and other fields. The characteristics of steel are high strength, light self-weight, good overall stiffness and strong deformation ability. Therefore, it is particularly suitable for building large-span and ultra-high and ultra-heavy buildings.
[0003] Currently, it is necessary to lift a prefabricated steel component by a hoisting device and align it with the prefabricated steel component to be connected. Then, support connecting plates are placed on both sides of the two prefabricated steel components, and then they are connected and assembled by multiple bolts. Therefore, when placing the support connecting plates and screwing the bolts, the hoisting device needs to keep lifting the connected prefabricated steel components all the time. As a result, the prefabricated steel components are prone to shaking during connection, which affects the connection efficiency. Therefore, new technical solutions need to be designed to solve this problem. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a prefabricated steel component with stable installation to solve the technical problem that the prefabricated steel components are prone to shaking during connection, which affects the connection efficiency.
[0005] To achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a prefabricated steel component with stable installation, including a vertical steel component and a horizontal steel component. One side of the vertical steel component is fixedly connected with an I-shaped connecting piece. The horizontal steel component is in the shape of an I. An I-shaped connecting cylinder is slidably sleeved outside the horizontal steel component. Two through holes are opened on both sides of one end of the horizontal steel component. Four screw rods are inserted into the four through holes, and first nuts are threadedly sleeved on the outer sides of the four screw rods. Multiple first insertion holes are opened on both sides of one end of the I-shaped connecting piece, and multiple second insertion holes are opened on both sides of one end of the horizontal steel component.
[0006] Preferably, rubber cover plates are arranged on both sides of the I-shaped connecting cylinder, and the two rubber cover plates are adapted to the outer sides of both ends of the I-shaped connecting cylinder, and the two rubber cover plates are elastic.
[0007] Preferably, permanent magnets are inlaid at the opposite ends of the two rubber cover plates, and the opposite ends of the two permanent magnets have opposite magnetic poles.
[0008] Preferably, the length of the screw rod is greater than the height of the I-shaped connecting cylinder.
[0009] Preferably, a second nut and a second nut are sleeved on the outer thread of the screw rod inside the I-shaped connecting cylinder.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] Through the combination of structures such as a horizontal steel member, an I-shaped connecting member, an I-shaped connecting cylinder, a first insertion hole, a second insertion hole, a perforation, a screw rod, and a first nut, when it is necessary to install a horizontal steel member, the horizontal steel member is hoisted to correspond to the I-shaped connecting member by a hoisting mechanism, and then the I-shaped connecting cylinder is pushed to the connection position of the horizontal steel member, and the perforation is aligned with the first insertion hole and the second insertion hole. Thus, the I-shaped connecting cylinder limits the hoisted horizontal steel member, and then the screw rod is inserted into the first insertion hole and the second insertion hole and the first nut is screwed to connect the horizontal steel member with the I-shaped connecting member, thereby avoiding the shaking of the horizontal steel member during connection and affecting the connection efficiency;
[0012] When connecting, the I-shaped connecting cylinder is placed outside the I-shaped connecting member and the horizontal steel member, thereby increasing the contact area between the I-shaped connecting cylinder and the I-shaped connecting member and the horizontal steel member. At the same time, by screwing the second nut and the third nut on both sides of the inner cavity of the I-shaped connecting cylinder, the firmness of the connection of the horizontal steel member is improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The present utility model will be further described below with reference to the drawings and embodiments:
[0019] Example 1: A prefabricated steel member with stable installation, seeFigures 1 to 4 , including a vertical steel member 1 and a horizontal steel member 2. One side of the vertical steel member 1 is fixedly connected with an I-shaped connecting piece 11. The horizontal steel member 2 is in the shape of an I. An I-shaped connecting cylinder 3 is slidably sleeved on the outside of the horizontal steel member 2. Two through holes 31 are respectively opened on both sides of one end of the horizontal steel member 2. Four screw rods 4 are inserted into the four through holes 31, and first nuts 42 are threadedly sleeved on the outside of the four screw rods 4. A plurality of first insertion holes 12 are respectively opened on both sides of one end of the I-shaped connecting piece 11. A plurality of second insertion holes are respectively opened on both sides of one end of the horizontal steel member 2. The length of the screw rod 4 is greater than the height of the I-shaped connecting cylinder 3. Second nuts 43 and third nuts 41 are threadedly sleeved on the outside of the screw rod 4 inside the I-shaped connecting cylinder 3. During work, when it is necessary to install the horizontal steel member 2, the horizontal steel member 2 is hoisted by a hoisting mechanism to correspond to the I-shaped connecting piece 11. Then, the I-shaped connecting cylinder 3 is pushed to the connection part of the horizontal steel member 2, and the through holes 31 are aligned with the first insertion holes 12 and the second insertion holes 21. Thus, the I-shaped connecting cylinder 3 limits the hoisted horizontal steel member 2. Then, the screw rod 4 is inserted into the first insertion hole 12 and the second insertion hole 21 and the first nut 42 is screwed to connect the horizontal steel member 2 with the I-shaped connecting piece 11, thereby avoiding the shaking of the horizontal steel member 2 during connection and affecting the connection efficiency. And during connection, the I-shaped connecting cylinder 3 is placed outside the I-shaped connecting piece 11 and the horizontal steel member 2, thereby increasing the contact area between the I-shaped connecting cylinder 3 and the I-shaped connecting piece 11 and the horizontal steel member 2. At the same time, by screwing the second nut 43 and the third nut 41 on both sides of the inner cavity of the I-shaped connecting cylinder 3, the firmness of the connection of the horizontal steel member 2 is improved.
[0020] Specifically, refer to Figure 2 and Figure 3 , rubber cover plates 5 are arranged on both sides of the I-shaped connecting cylinder 3, and the two rubber cover plates 5 are both adapted to the outer sides of the two ends of the I-shaped connecting cylinder 3, and the two rubber cover plates 5 are both elastic. Permanent magnets 51 are embedded at the opposite ends of the two rubber cover plates 5, and the opposite ends of the two permanent magnets 51 have opposite magnetic poles. After the horizontal steel member 2 is connected, the rubber cover plates 5 are covered from both sides. Thus, the permanent magnets 51 of the two rubber cover plates 5 adsorb each other, thereby improving the stability of the rubber cover plates 5 connected to the outside of the I-shaped connecting cylinder 3, and further being able to protect the screw rod 4, the first nut 42, the second nut 43 and the third nut 41, and further extending the service life of the screw rod 4, the first nut 42, the second nut 43 and the third nut 41.
