Description

Technical Field

[0001] This utility model relates to a connection structure for building engineering, specifically an ALC wall panel installation structure suitable for H-shaped steel frames. Background Technology

[0002] In the construction industry, ALC (lightweight aerated concrete) wall panels are increasingly used in residential and commercial buildings due to their excellent sound insulation, thermal insulation, and fire resistance. However, existing ALC wall panel connection methods have some problems and drawbacks. Traditional connection methods include rigid connections and flexible connections. For rigid connections, the ALC wall panels need to be connected to the frame structure to form a rigid whole. While ensuring a tight connection between the wall panels, excessive rigidity can easily lead to cracking of the wall panels during earthquakes. For flexible connections, the ALC wall panels need to be able to move relative to the frame structure. Excessive flexibility can affect the tightness of the connection. Utility Model Content

[0003] The purpose of this invention is to provide an ALC wall panel installation structure suitable for H-shaped steel frames, so as to solve the problem of excessive rigidity or flexibility in existing ALC wall panel connection methods.

[0004] This utility model is implemented as follows: An ALC wall panel installation structure suitable for H-shaped steel frames includes an ALC wall panel, H-shaped steel frame beams located at the upper and lower ends of the ALC wall panel, and connecting components. The two side plates and one middle plate of the connecting components form a U-shaped structure. Two internal threaded holes are provided along the length direction of the middle plate. An elongated hole is provided on the flange of the H-shaped steel frame beam. The length direction of the elongated hole is consistent with the length direction of the H-shaped steel frame beam, and the length of the elongated hole is consistent with the distance between the two internal threaded holes. Two first bolts are inserted into the elongated hole, and the ends of the two first bolts are respectively threaded to the two internal threaded holes. The ends of the ALC wall panel are located between the two side plates of the connecting components and are fixedly connected to each other.

[0005] As a further improvement to the ALC wall panel installation structure applicable to H-shaped steel frames, a flexible pad layer is provided on the inner side of the side panel.

[0006] As a further improvement of the ALC wall panel installation structure applicable to H-shaped steel frames, at least one through hole is opened on each of the two side plates, and a through hole corresponding to the through hole is opened in the middle of the upper / lower end of the ALC wall panel. The second bolt passes through the through hole of the two side plates and the through hole of the ALC wall panel, and a nut is screwed on the second bolt.

[0007] As a further improvement to the ALC wall panel installation structure applicable to H-shaped steel frames, the length of the connecting member is one-third of the width of the ALC wall panel.

[0008] As a further improvement of the ALC wall panel installation structure applicable to H-shaped steel frames, the ALC wall panel is connected to the wing plate on one side of the H-shaped steel frame beam, and the side of the ALC wall panel coincides with the edge of the wing plate.

[0009] The ALC wall panel of this invention is fixedly connected to the connecting component and then connected to the H-shaped steel frame beam via the connecting component. Two first bolts are located at both ends of an elongated hole. Under normal circumstances, the two first bolts restrict the position of the connecting component and the ALC wall panel, creating a rigid connection between the ALC wall panel and the H-shaped steel frame beam, preventing movement of the ALC wall panel and ensuring a tight connection. During an earthquake, if the load exceeds a certain limit at the connection point between the first bolt and the internal thread of the connecting component, the connection point will break, allowing the ALC wall panel to move to some extent and preventing cracking and damage.

[0010] In addition, the ALC wall panel of this utility model has a large contact area with the connecting component, and a flexible pad is set between the ALC wall panel and the side plate of the connecting component to prevent the wall panel from being excessively squeezed and stress concentrated, thus preventing premature cracks.

[0016] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0017] like Figs. 1-4As shown, this utility model is applicable to the installation structure of ALC wall panels 3 in H-shaped steel frames, including ALC wall panels 3, H-shaped steel frame beams 1 located at the upper and lower ends of the ALC wall panels 3, and connecting members 2. Several ALC wall panels 3 are installed side by side between two upper and lower H-shaped steel frame beams 1, and the upper and lower ends of the ALC wall panels 3 are connected to the H-shaped steel frame beams 1 through the connecting members 2.

[0018] The two side plates 2-1 and one middle plate 2-2 of the connecting member 2 form a U-shaped structure. The end of the ALC wall panel 3 is located inside the U-shaped connecting member 2. The ALC wall panel 3 is located between the two side plates 2-1 of the connecting member 2 and is fixedly connected to each other.

[0019] To connect the connecting component 2 to the H-shaped steel frame beam 1, two internal threaded holes 2-4 are provided along the length direction on the intermediate plate 2-2. An elongated hole 4 is provided on the flange of the H-shaped steel frame beam 1. The length direction of the elongated hole 4 is consistent with the length direction of the H-shaped steel frame beam 1, and the length of the elongated hole 4 is consistent with the distance between the two internal threaded holes 2-4. Two first bolts 5 are inserted into the elongated hole 4, and the ends of the two first bolts 5 are threaded to the two internal threaded holes 2-4 respectively.

[0020] Two first bolts 5 are fixed in the internal threaded holes 2-4. Since the spacing between the two first bolts 5 is consistent with the length of the elongated hole 4, the first bolts 5 will not move within the elongated hole 4. The connecting component 2 and the H-shaped steel frame beam 1 are mutually fixed. Therefore, under normal circumstances, there will be no relative movement between the ALC wall panel 3 and the H-shaped steel frame beam 1, ensuring the tightness of the connection after the ALC wall panel 3 is installed. Since only the end of the first bolt 5 is threaded into the internal threaded hole 2-4, the load that this connection node can withstand is limited. When an earthquake occurs, if the load at this connection node exceeds a certain value, the connection between the first bolt 5 and the internal threaded hole 2-4 will be damaged, generally manifested as damage to the bolt threads. This causes the first bolt 5 to be unable to continue restricting the movement of the ALC wall panel 3, allowing the ALC wall panel 3 to move to a certain extent, thereby preventing cracking and damage to the wall panel.

[0021] The limit value of the load that the connection node can bear can be adjusted by the length of the first bolt 5 screwed into the internal threaded hole 2-4.

[0022] The two sides of the ALC wall panel 3 contact the two side plates 2-1 of the connecting member 2, and the end face of the ALC wall panel 3 contacts the middle plate 2-2 of the connecting member 2, so that the ALC wall panel 3 and the connecting member 2 have a large contact area and reduce the contact stress.

[0023] Preferably, a flexible pad 7 is provided on the inner side of the side plate 2-1, and the side of the ALC wall panel 3 contacts the flexible pad 7 to prevent the side plate 2-1 from excessively squeezing the wall panel and causing stress concentration, thus preventing premature cracking.

[0024] The flexible pad 7 can be made of materials such as rubber, synthetic resin, or polytetrafluoroethylene.

[0025] At least one through hole 2-3 is opened on each of the two side plates 2-1, and the through holes 2-3 on the two side plates 2-1 correspond to each other. At the same time, a through hole corresponding to the through hole 2-3 is opened in the middle of the upper / lower end of the ALC wall panel 3. The second bolt 6 passes through the through hole 2-3 of the two side plates 2-1 and the through hole of the ALC wall panel 3, and a nut is screwed on the second bolt 6. The ALC wall panel 3 is fixed together with the connecting member 2 by screwing in the nut.

[0026] In this specific embodiment, there are two through holes 2-3 on the side plate 2-1, and the two through holes 2-3 are distributed along the length direction of the side plate 2-1. After the second bolt 6 is passed through multiple through holes 2-3, the pressure distribution of the bolt on the side plate 2-1 can be more uniform, reducing local stress concentration.

[0027] In this specific embodiment, the length of the connecting member 2 is one-third of the width of the ALC wall panel 3. The longer length of the connecting member 2 increases the contact area with the ALC wall panel 3, reduces stress concentration, and prevents excessive compression of the ALC wall panel 3 after the second bolt 6 is tightened.

[0028] During installation, ALC wall panel 3 is connected to the flange on one side of H-shaped steel frame beam 1, and the side of ALC wall panel 3 coincides with the edge of the flange.

[0029] According to the location of ALC wall panel 3 in the drawings, determine the opening position of the elongated hole 4 on the H-shaped steel frame beam 1 and make the hole in advance; pre-open the internal threaded hole 2-4 and the through hole 2-3 on the connecting member 2, place the flexible pad 7 on the inner side of the side plate 2-1 of the connecting member 2, and install it in the middle of the upper and lower ends of the ALC wall panel 3. After fixing, use an impact drill to penetrate the through hole opening position of the ALC wall panel 3, and then pass the second bolt 6 through and apply pre-tightening force to tighten the connecting member 2; then start installing the wall panel. After aligning the internal threaded hole 2-4 with the elongated hole 4, use the first bolt 5 to fix the connecting member 2 to the H-shaped steel frame beam 1 to complete the installation of the ALC wall panel 3.
