Description

Technical Field

[0001] This utility model relates to an installation structure for a cement fiberboard curtain wall, belonging to the field of building curtain wall technology. Background Technology

[0002] Cement fiberboard curtain walls, due to their combination of decoration and practicality, have been widely used in building exterior wall projects. Their conventional installation structure mainly consists of keel, back bolts and cement fiberboard. Cement fiberboard is usually installed on the keel through the back bolts. For some special curtain wall shapes, there are also methods to set an adjustable structure between the back bolts and the keel to ensure installation accuracy.

[0003] However, the adjustment functions of existing installation structures are mostly concentrated on a single component, lacking the ability to adjust at various nodes. This makes it easy for various errors to accumulate during construction, which not only affects the flatness and appearance consistency of the curtain wall installation, but also increases the difficulty of later adjustments, making it difficult to meet the high standards required for curtain wall installation accuracy in current building projects. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an installation structure for cement fiberboard curtain walls.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an installation structure for a cement fiberboard curtain wall, comprising steel columns, steel beams, a cement fiberboard body, GRC stainless steel connectors, aluminum alloy hangers, and angle steel brackets;

[0006] Steel angle brackets are provided on both sides of the steel column. A first elongated hole in the horizontal direction is opened on the steel angle bracket. A first adjusting bolt is inserted into the first elongated hole. The end of the steel beam is installed on the steel angle bracket through the cooperation of the first adjusting bolt and the first elongated hole.

[0007] The aluminum alloy bracket is fixed to the back side of the cement fiberboard body by a GRC stainless steel connector. One end of the angle steel bracket is connected to the aluminum alloy bracket, and the other end of the angle steel bracket has a second elongated hole in the front-back direction. A second adjusting bolt is inserted into the second elongated hole. The angle steel bracket is installed on the steel beam through the cooperation of the second adjusting bolt and the second elongated hole.

[0008] Preferably, the top of the aluminum alloy bracket has a groove, the top of the angle steel bracket is embedded in the groove, and the top of the aluminum alloy bracket is provided with a height adjustment bolt, which passes through the groove and cooperates with the top of the angle steel bracket; a stainless steel fixing bolt is provided on the top side of the aluminum alloy bracket, which presses the angle steel bracket from the side.

[0009] Preferably, the lower side of the aluminum alloy hanger has a drag section, which abuts against the angle steel hanger and supports the angle steel hanger from the outside.

[0010] Preferably, the contact surfaces of the aluminum alloy hanger and the angle steel bracket are both provided with sealant.

[0011] Preferably, a flexible gasket is provided between the aluminum alloy hanger and the cement fiberboard body, and the GRC stainless steel connector passes through the middle of the aluminum alloy hanger and the flexible gasket.

[0012] Preferably, the side of the angle steel bracket connected to the steel beam is provided with a toothed structure, and a toothed washer is fitted on the second adjusting bolt, the toothed washer cooperating with the toothed structure on the angle steel bracket.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] 1. This utility model achieves horizontal adjustment of the steel beam through the first long hole, front and back adjustment of the angle steel bracket through the second long hole, and vertical adjustment of the panel through the height adjustment bolt, forming a three-dimensional decentralized adjustment system of horizontal, front and back, and vertical. Each node can be adjusted independently without interference, and the errors of steel component installation, wall flatness, and panel size can be adjusted separately to avoid the cumulative error affecting the overall flatness of the curtain wall.

[0015] 2. By integrally machining the drag section on the lower side of the aluminum alloy bracket, the angle steel bracket can be supported from the outside, which can actively share the vertical load of the cement fiberboard and avoid fatigue damage to the GRC stainless steel connectors and height adjustment bolts due to long-term bearing of the full weight; at the same time, in the event of accidental loosening of the bolts, the drag section can prevent the angle steel bracket from falling off, thereby increasing the safety guarantee for the installation of high-rise curtain walls and reducing the risk of falling.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] As attached Figure 1-2 As shown, the installation structure of the cement fiberboard curtain wall of this utility model includes steel columns 1, steel beams 2, cement fiberboard body 3, GRC stainless steel connectors 4, aluminum alloy hangers 5, and angle steel brackets 6.

[0024] Steel angle brackets 11 are provided on both sides of the steel column 1. The steel angle brackets 11 are fixed to the steel column 1 by welding. The steel angle brackets 11 have a first elongated hole 111 in the horizontal direction. A first adjusting bolt 112 is inserted into the first elongated hole 111. In this embodiment, the steel angle brackets 11 have two first elongated holes 111. The end of the steel beam 2 is installed on the steel angle brackets 11 through the cooperation of the first adjusting bolt 112 and the first elongated hole 111. During construction, by loosening the first adjusting bolt 112, the steel beam 2 is pushed along the horizontal direction of the first elongated hole 111 to achieve fine adjustment of the steel beam 2 in the left and right directions. After the position of the steel beam 2 is determined, the first adjusting bolt 112 is tightened to fix the steel beam 2 firmly.

[0025] Among them, the steel angle bracket 11 serves as a transitional connector between the steel beam 2 and the steel column 1, which can distribute the load of the steel beam 2 and prevent the steel column 1 from being deformed due to excessive local stress.

[0026] The aluminum alloy hanger 5 is fixed to the back side of the cement fiberboard body 3 by the GRC stainless steel connector 4. In this embodiment, a flexible gasket 8 is provided between the aluminum alloy hanger 5 and the cement fiberboard body 3. The GRC stainless steel connector 4 passes through the middle of the aluminum alloy hanger 5 and the flexible gasket 8 to fix the aluminum alloy hanger 5 and the cement fiberboard body 3. The load-bearing capacity of the GRC stainless steel connector 4 is better than that of conventional back bolts, which can ensure that the cement fiberboard body 3 will not fall off when suspended for a long time.

[0027] In this embodiment, the flexible gasket 8 can be a EPDM rubber gasket, which can buffer the temperature deformation between the cement fiberboard body 3 and the aluminum alloy hanger 5, and increase the fit between the two to adapt to the slight unevenness on the back side of the cement fiberboard body 3, while reducing abnormal noise during vibration.

[0028] One end of the angle steel bracket 6 is connected to the aluminum alloy bracket 5, and the other end of the angle steel bracket 6 has a second elongated hole 61 in the front-back direction. A second adjusting bolt 62 is inserted into the second elongated hole 61. The angle steel bracket 6 is installed on the steel beam 2 through the cooperation of the second adjusting bolt 62 and the second elongated hole 61. The connection method between the angle steel bracket 6 and the steel beam 2 is the same as the connection method between the steel beam 2 and the steel angle bracket 11, which will not be described in detail here. By setting the second adjusting bolt 62 and the second elongated hole 61, the installation error of the cement fiberboard body 3 is corrected, and the overall convexity or concavity of the curtain wall due to insufficient flatness of the panel is avoided.

[0029] Among them, as attached Figure 3 As shown, a toothed structure 63 is provided on the side where the angle steel bracket 6 connects to the steel beam 2. A toothed washer 621 is fitted on the second adjusting bolt 62. The toothed washer 621 cooperates with the toothed structure 63 on the angle steel bracket 6 to form an anti-loosening engagement structure, which can stably maintain the front and rear position of the angle steel bracket 6 and prevent the cement fiberboard body 3 from shifting due to bolt loosening, thus ensuring the flatness of the curtain wall for long-term use.

[0030] Further details are attached. Figure 2 , 4 As shown, the top of the aluminum alloy bracket 5 is provided with a groove 51, and the top of the angle steel bracket 6 is embedded in the groove 51 to facilitate the positioning of the angle steel bracket 6. The top of the aluminum alloy bracket 5 is provided with a height adjustment bolt 52, which passes through the groove 51 and cooperates with the top of the angle steel bracket 6. During construction, the height adjustment bolt 52 can be tightened or loosened to make a fine adjustment in the vertical direction of the cement fiberboard body 3 to ensure the height deviation of the cement fiberboard body 3 and ensure that there is no height difference when multiple cement fiberboard bodies 3 are spliced.

[0031] Furthermore, stainless steel fixing bolts 53 are inserted through the top side of the aluminum alloy bracket 5. The stainless steel fixing bolts 53 press the angle steel bracket 6 from the side. After the height of the angle steel bracket 6 is adjusted, tighten the stainless steel fixing bolts 53 to press the angle steel bracket 6 from the side. This can prevent the angle steel bracket 6 from shaking in the groove 51, further locking the height position and avoiding height deviation caused by wind or temperature deformation in the later stage.

[0032] The first long hole 111 enables horizontal adjustment of the steel beam 2, the second long hole 61 enables front-to-back adjustment of the angle steel bracket 6, and the height adjustment bolt 52 enables vertical adjustment of the panel, forming a three-dimensional decentralized adjustment system of horizontal, front-to-back, and vertical. Each node can be adjusted independently without interference, and the errors in steel component installation, wall flatness, and panel size can be adjusted separately to avoid the cumulative error affecting the overall flatness of the curtain wall.

[0033] Furthermore, the lower side of the aluminum alloy hanger 5 has a drag portion 54, which abuts against the angle steel bracket 6 and supports the angle steel bracket 6 from the outside. In this embodiment, the drag portion 54 is integrally formed on the aluminum alloy hanger 5. When the angle steel bracket 6 is connected to the aluminum alloy hanger 5, the drag portion 54 supports the bottom of the angle steel bracket 6 from the outside to share the vertical load of the angle steel bracket 6, and avoids fatigue damage to the GRC stainless steel connector 4 and the height adjustment bolt 52 due to long-term bearing of the weight of the cement fiberboard body 3.

[0034] As a preferred embodiment, the contact surfaces of the aluminum alloy bracket 5 and the angle steel bracket 6 are both provided with sealant 7 to fill the tiny gaps in the contact surfaces and prevent rainwater and dust from seeping into the interior of the curtain wall.

[0035] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
