[0002] At present, prefabricated steel structure buildings are vigorously developing in my country, with a large market demand. Prefabricated buildings will continue to become the development trend of future buildings. For prefabricated steel structure buildings, the current structural system is very mature and can be fully guaranteed in terms of structural safety. The difficulty lies in the selection of three-board components and the connection method between them and the main structure. As one of the three-board components, the installation details of the wall ALC strips are one of the key points that directly affect the quality and sensory experience of the overall residential wall. ALC strips, also known as autoclaved sand aerated concrete panels, are made of silica sand, cement, quicklime, and gypsum as raw materials, and aluminum powder as a foaming agent. After a series of process processes (batch, reinforcement, foaming, cutting), and finally high-temperature, high-pressure steam curing, the porous silicate products are obtained, which have a series of advantages such as light weight and high strength. However, in the actual construction process, when the ALC strips are spliced ​​and installed, it is easy to produce deviation during the installation and adjustment process, and it is easy to move under the action of external forces, making the installation of the ALC strip installation nodes very inconvenient and inefficient.

[0031] Embodiment 1

[0032] Figure 1 is a front view of an embodiment of a connecting piece, Figure 2 for Figure 1 The top view of the embodiment shown, with reference to Figure 1 , 2The connector 3 of the embodiment of the present invention includes a connecting part, a first pipe clamp 31 and a second pipe clamp 32. The connecting part includes a first connecting section 33 and a second connecting section 34. The first pipe clamp 31 and the second pipe clamp 32 are respectively perpendicular to the first connecting section 33 and symmetrically arranged on the opposite sides of the first connecting section 33 to form a connector 3 with a double-sided pipe clamp structure. Therefore, the connector 3 can facilitate the installation of the ALC strip board installation node. The first connecting section 33 is located between two adjacent ALC strip boards. The first pipe clamp 31 and the second pipe clamp 32 of the connector 3 are respectively connected to the two adjacent ALC strip boards, so that the connector 3 at a node can fix the two adjacent ALC strip boards at the same time, making the fixation more firm and the installation process more convenient. The specific ALC strip board installation node and the installation process will be described in detail later. Here, only the structural setting of the connector 3 is described.

[0033] During implementation, the positions of the first pipe clamp 31 and the second pipe clamp 32 may be staggered to disperse the stress, for example Figure 1 In the illustrated embodiment, the first pipe clamp 31 and the second pipe clamp 32 are staggered in longitudinal position.

[0034] The second connecting section 34 is bent toward one side of the first connecting section 33 to facilitate fixed connection with the upper mounting structure of the ALC strip, so that the ALC strip can be fixedly connected at a desired position. According to the connection requirements, the angle between the second connecting section 34 and the first connecting section 33 is set as required. In this embodiment, the angle between the second connecting section 34 and the first connecting section 33 is a right angle, which can be connected to the steel beam above the ALC strip, and is suitable for built-in or external partition walls below the steel beam. The connection is convenient and firm.

[0035] Specifically, the connecting portion can be a plate-like structure, which helps to reduce the width of the joints between adjacent ALC plates and make the joints smoother; the first pipe clamp 31 and the second pipe clamp 32 are respectively connected to the two side plate surfaces of the first connecting section 33, and the first connecting section 33 and the second connecting section 34 can be formed by bending the same plate part, or by splicing two plates together.

[0036] Embodiment 2

[0037] Figure 3 This is a schematic diagram of an embodiment of an ALC strip board installation node structure. Figure 4 is a schematic diagram of the structure of adjacent ALC strips and connecting members 3 in one embodiment, Figure 5 This is a cross-sectional view of an embodiment of the ALC strip board installation node structure. Please also refer to Figures 3 to 5, and combined with the description of the above-mentioned connecting member 3, the ALC strip board installation node structure of the embodiment of the present invention can be used for the installation of the partition wall below the steel beam 1. The ALC strip board installation node structure includes the steel beam 1, the above-mentioned connecting member 3 and the adjacent ALC strip boards 2 connected by the connecting member 3. The adjacent ALC strip boards 2 are defined as the first ALC strip board 21 and the second ALC strip board 22. The first ALC strip board 21 and the second ALC strip board 22 are arranged below the steel beam 1; the first connecting section 33 is located between the first ALC strip board 21 and the second ALC strip board 22 of the adjacent ALC strip boards, the first pipe clamp 31 is embedded in the first ALC strip board 21, and the second pipe clamp 32 Embedded in the second ALC strip 22; the second connecting section 34 is used to connect the steel beam 1, and can be fixedly connected to the steel beam 1 by welding. The second connecting section 34 is welded to the lower flange plate of the steel beam 1 and hidden in the top surface of the ALC strip. Therefore, combined with the structure of the above-mentioned connecting member 3, it can be known that in the ALC strip installation node structure, two adjacent ALC strips can be fixedly connected at the same time through a connecting member 3. At the same time, it can be fixedly connected to the steel beam 1 through the second connecting section 34 of the connecting member 3. The structure is simple and can realize assembled installation. Therefore, it is easy and firm to install, which solves the technical problem of inconvenient node installation of ALC strips in steel structure buildings.

[0038] A flexible material 4, such as a foaming adhesive, is filled between the top of the first ALC strip 21 and the second ALC strip 22 and the steel beam 1 to form a flexible connection. There is a joint between the first ALC strip 21 and the second ALC strip 22, and the joint is filled with bonding mortar 5. In specific implementation, when the first pipe clamp 31 and the second pipe clamp 32 are inserted into the first ALC strip 21 and the second ALC strip, a distance is left, so that there is a gap 6 between the first connection section 33 and the first ALC strip 21 and the second ALC strip 22. When the bonding mortar 5 fills the joint, the bonding mortar 5 is also filled into the gap 6.

[0039] In this embodiment, the first ALC strip 21 is provided with a recessed structure at the corresponding connecting member 3, and the second ALC strip 22 is provided with a raised structure that can match the raised structure at the corresponding connecting member 3, thereby forming a joint 7 with an irregular cross-section at the joint of adjacent ALC strips, which helps to increase the connection area of ​​adjacent ALC strips and improve the stability of the joint connection.

[0040] The patent "A non-welded flexible steel beam clamp and U-shaped clamp node structure for the interior wall of an ALC strip board" with publication number CN206941882U provides a non-welded flexible steel beam clamp and U-shaped clamp node structure for the interior wall of an ALC strip board in an assembled steel structure residential building. The steel beam clamp is formed by bending a steel plate, and is provided with a clamping groove matching the steel beam. The inner sides of the bent parts on both sides of the clamping groove are provided with clamping limit protrusions. The outer bottom surface of the middle part of the steel beam clamp is the welding connection surface of the U-shaped clamp component.

[0041] The technical solution provided by this patent application has the following disadvantages:

[0042] 1. The patent only proposes the node sample of the U-shaped card, but does not provide a detailed description of its scope of application. If the width of the ALC wall is smaller than the width of the beam flange plate, the width of the U-shaped card will be narrowed accordingly, so whether the card-mounted limit protrusion can still be applied.

[0043] 2. The entire U-shaped clamping device is connected to the flange plate by the clamping limit protrusion, and the connection strength cannot be guaranteed.

[0044] The ALC strip installation node structure and its connecting member 3 provided in the embodiment of the present invention have a connecting member 3 with double-sided pipe clamps installed between the vertical joints of the two ALC strips 2. The pipe clamps on both sides of the connecting plate directly extend into the side mounting holes of the ALC strips 2 that have been prefabricated in advance, so that the pipe clamps at one node can simultaneously fix two adjacent ALC strips 2. The second connecting section 34 of the connecting member 3 is bent at the top of the ALC strip and welded to the lower flange plate of the steel beam 1, hidden in the top surface of the ALC strip, so that the finished surface of the wall is more beautiful and integrated; it is suitable for the installation of ALC strips of all thicknesses, can optimize the construction sequence and method of the ALC strips, and improve the accuracy of the strip installation.

[0045] Embodiment 3

[0046] The embodiment of the present invention also provides an assembled installation method based on the above-mentioned ALC strip board installation node structure. Figure 6 This is a sequence diagram of an assembled installation method of an ALC strip board installation node according to an embodiment, combined with the above-mentioned ALC strip board installation node structure and referring to Figure 6 , refer to ABCD in the figure for installation sequence:

[0047] A first ALC strip is arranged below the steel beam;

[0048] Installing a connector on one side of the first ALC strip, embedding the first pipe clamp into the first ALC strip, and fixing the second connecting section of the connector to the steel beam;

[0049] The second ALC strip is installed on one side of the first ALC strip so that the second pipe clamp is embedded in the second ALC strip. Mounting holes can be pre-arranged at corresponding positions of the ALC strip to facilitate the insertion of the first pipe clamp or the second pipe clamp during installation.

[0050] The above installation method realizes the sequential installation of ALC strips at the ALC strip installation nodes. It can first measure, locate and install one of the ALC strips, then install the fixed connecting parts, and then install another ALC strip on the other side of the connecting parts, which effectively prevents the deviation or displacement of the ALC strips during the installation process, improves the installation accuracy, ensures the flushness of the installation surface, and has strong operability and feasibility.

[0051] A flexible material, such as a foaming adhesive, is filled between the top of the first ALC strip and the second ALC strip and the steel beam to form a flexible connection. The joint between the first ALC strip and the second ALC strip is filled with bonding mortar. When installing the connecting plate, a distance is left when the first pipe clamp and the second pipe clamp are inserted into the first ALC strip and the second ALC strip, so that there is a gap between the first connecting section and the first ALC strip and the second ALC strip, respectively, so that the bonding mortar can be filled into the gap, which helps to enhance the stability of the connection.

[0052] The first ALC strip can be positioned by using the conventional method of vertical laying out a line. According to the design position, the required positioning lines are marked on the ground, wall and ceiling, and the first ALC strip is positioned and set according to the positioning lines.

[0053] The patent application with publication number CN106499091A, "A method for constructing an assembled partition wall based on ALC boards", provides a method for constructing an assembled partition wall based on ALC boards. When installing the strips, manual horizontal and vertical compression is adopted, which is conducive to the bonding of the adhesive with the board and the concrete surface, and ensures that there is no large stress on the wall and the joints after the adhesive solidifies and shrinks, thereby greatly reducing the possibility of cracks in the wall and the joints; during the construction process, the installation of the ALC strips is further adjusted and calibrated, thereby improving the wall forming quality.

[0054] The technical solution provided by this patent application has the following disadvantages:

[0055] 1. The installation is carried out by manual horizontal and vertical extrusion to combine the adhesive with the plate and concrete surface. This method is inefficient, and the manual extrusion method cannot ensure that the bonding force and gap of each joint surface are uniform, and the molding is poor.

[0056] 2. This construction method does not have fasteners to fix the ALC strips, which can easily cause displacement during installation and adjustment, especially under the action of external forces caused by manual compression.

[0057] In other conventional structures and solutions, some use U-shaped clips to fix the top of the strips. The U-shaped clips are fixed to the structural beams and the plates with a nail gun between the top seams of the two strips.

[0058] The ALC strip installation node structure provided by the embodiment of the present invention and the assembled installation method based on the ALC strip installation node structure can realize sequential installation. First, an ALC strip at the end edge is positioned and set under the steel beam, and then the connecting piece is installed, and then the next ALC strip is installed. The connecting piece has a double-sided pipe clamp. It is only necessary to directly insert the adjacent ALC strip into the pipe clamp according to the position of the pipe clamp on the back side. The sequential installation is realized in the manner of ALC strip-connecting piece-ALC strip. The installation method is simple and easy to operate, which improves the installation efficiency and ensures the flatness of the wall appearance. In addition, the fixing method is firm. One connecting piece can fix two ALC strips at the same time, so that the fixing of the strips is more stable, and the stability of the structure is improved. It is suitable for all assembled buildings with steel structure as the main body and ALC strips as partition walls, such as residential and commercial buildings with steel structure as the main frame. The structural steel beams can adopt I-beams, which have a wide range of promotion.

[0059] The above are only preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
