Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, and in particular to an open hollow terracotta panel curtain wall structure and its installation method. Background Technology

[0002] Terracotta panels are made from natural clay, which is extruded under high pressure, dried at low temperature, and then fired at a high temperature of 1200–1250 ℃. Compared with traditional curtain wall materials such as glass, aluminum panels, and stone, terracotta panels have high strength, excellent seismic and wind pressure resistance, no additives, no light pollution, and a rich and controllable surface texture, which can meet the requirements of architects for different building facades. They have been widely used in various building curtain walls.

[0003] Currently, terracotta panel curtain wall structures, as described in Chinese invention patent applications 201310145254.8 (titled "An Installation Structure for Terracotta Panel Curtain Wall") and 200910100702.6 (titled "A Hanging Structure for Terracotta Panel Curtain Wall"), generally suffer from the following problems: First, terracotta panels are typically installed on a steel frame using upper and lower brackets. However, due to differences in the positions of these brackets, the installed terracotta panels are uneven, or there is inconsistency in flatness between adjacent panels. Second, the installation of terracotta panels on the steel frame using brackets typically employs bolt connections, which is inconvenient for installation and maintenance, resulting in low construction efficiency. Third, terracotta panels generally use only one adjusting component to adjust the vertical position of the left and right sides, causing the panels to tilt and resulting in warping on the surface.

[0004] Based on this, an open-type hollow terracotta panel curtain wall structure and installation method are designed. Summary of the Invention

[0005] The present invention aims to overcome the defects in the prior art and provide an open hollow terracotta panel curtain wall structure and installation method.

[0006] To achieve the above objectives, the technical solution adopted by this invention is: an open hollow terracotta panel curtain wall structure, comprising terracotta panels, wherein an aluminum alloy hanger is fixedly installed on the side of the terracotta panel near the main structure; comprising a keel steel frame, wherein an aluminum alloy bracket is fixedly installed on the keel steel frame to engage with the aluminum alloy hanger, wherein the aluminum alloy bracket includes a fixing part connected to the keel steel frame, and the fixing part has an elongated hole for adjusting the front and rear position of the aluminum alloy bracket; comprising a fastener assembly, wherein the fastener assembly is located on top of the aluminum alloy hanger and the aluminum alloy bracket for adjusting the vertical distance between the aluminum alloy hanger and the aluminum alloy bracket.

[0007] As a preferred embodiment of the present invention, a plurality of hollow cavities are arranged in parallel along the length of the terracotta plate. The hollow cavities can accommodate U-shaped aluminum connectors. Each U-shaped aluminum connector corresponds to one aluminum alloy hanger. Bolts pass through the aluminum alloy hanger, the terracotta plate and the U-shaped aluminum connector to achieve the connection of the three.

[0008] In a preferred embodiment of the present invention, the aluminum alloy pendant includes a first pendant connecting portion and a second pendant connecting portion; the aluminum alloy code holder includes a first code holder connecting portion and a second code holder connecting portion, wherein the first code holder connecting portion is covered by the first pendant connecting portion, and the second code holder connecting portion covers the second pendant connecting portion.

[0009] In a preferred embodiment of the present invention, a hanging bending portion is formed on the second hanging component connecting portion, and a code holder bending portion is formed on the first code holder connecting portion. The bottom of the first hanging component connecting portion is opposite to the code holder bending portion, and the top of the second code holder connecting portion is opposite to the hanging component bending portion.

[0010] As a preferred embodiment of the present invention, the fastener assembly includes a first fastener and a second fastener. The first fastener passes through the first pendant connecting part and the first code base connecting part to connect the aluminum alloy pendant and the aluminum alloy code base. The second fastener passes through the first pendant connecting part and abuts against the first code base connecting part, thereby controlling the vertical distance between the aluminum alloy pendant and the aluminum alloy code base.

[0011] As a preferred embodiment of the present invention, there are at least two aluminum alloy hangers located on the same horizontal line as the terracotta slab, and the aluminum alloy hangers further include an abutment portion, which connects the first hanger connecting portion and the second hanger connecting portion.

[0012] As a preferred embodiment of the present invention, the keel steel frame includes a steel frame and a steel square tube. The steel frame includes a mounting base, and a first snap-fit ​​is formed on the top of the mounting base. The steel square tube includes a steel plate, and a second snap-fit ​​is formed on the steel plate to engage with the first snap-fit.

[0013] As a preferred embodiment of the present invention, an angle steel is provided on the side of the steel square tube facing the terracotta panel, and an aluminum alloy bracket is installed on the angle steel.

[0014] As a preferred embodiment of the present invention, a waterproof membrane is also provided between the keel steel frame and the main structure.

[0015] An installation method for an open-type hollow terracotta panel curtain wall structure, including... Step 1: Install a waterproof membrane between the main structure and the keel steel frame. The steel frame and steel square tube of the keel steel frame are connected by snap-fitting through the first snap-fit ​​and the second snap-fit. Step 2: The bolt passes through the angle steel and the elongated hole of the fixing part of the steel square tube and is locked by the nut to realize the installation of the aluminum alloy bracket on the steel square tube; Step 3: The bolt passes through the aluminum alloy hanger, terracotta plate, and U-shaped aluminum connector and is locked by the nut to complete the installation of the aluminum alloy hanger on the terracotta plate; Step 4: The aluminum alloy hanger and the aluminum alloy bracket are inserted and matched, with the bottom of the first hanger connecting part facing the bent part of the bracket, and the top of the second bracket connecting part facing the bent part of the hanger. Step 5: The first fastener passes through the first pendant connection part and the first code base connection part to connect the aluminum alloy pendant and the aluminum alloy code base. The second fastener passes through the first pendant connection part and abuts against the first code base connection part, thereby controlling the vertical distance between the aluminum alloy pendant and the aluminum alloy code base.

[0016] The beneficial effects of this invention are: 1. Compared with traditional terracotta panel curtain wall structures, this invention ensures the flatness of the same terracotta panel and the uniform flatness between adjacent terracotta panels by adjusting the horizontal distance between the aluminum alloy brackets at different positions at the top and bottom and the keel steel frame. By adjusting the fastener components on different aluminum alloy hangers on the same horizontal line, the terracotta panels are prevented from tilting, avoiding the warping of the terracotta panel surface. The above adjustment steps are simple and few, making it convenient for practical applications.

[0017] 2. This invention can fix the terracotta panels to the keel steel frame by simply plugging in the aluminum alloy hangers and aluminum alloy brackets. Compared with bolt connections, it is easier to install, speeds up the construction process, facilitates subsequent maintenance and replacement, and reduces maintenance costs.

[0018] 3. The hollow cavity of the terracotta board in this invention reduces its weight, making it easier to hang the terracotta board on the keel steel frame and increasing the stability of the terracotta board hanging; while the aluminum alloy hanger, together with the U-shaped aluminum connector, is installed on the terracotta board, ensuring the stability and adjustability of the aluminum alloy hanger installation.

[0019] 4. The present invention defines the lowest position of the terracotta plate in the keel steel frame by the first and second connecting parts of the aluminum alloy hanger and the first and second connecting parts of the aluminum alloy bracket. When the fastener assembly controls the vertical distance between the aluminum alloy hanger and the aluminum alloy bracket, the vertical distance between the terracotta plate and the keel steel frame will be adjusted to ensure that the terracotta plate does not tilt.

[0020] 5. The first fastener in the fastener assembly of the present invention also serves to fasten the aluminum alloy hanger and the aluminum alloy bracket, and plays a role in preventing jumping and limiting the terracotta plate after installation, thus ensuring the stability of the terracotta plate.

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

[0023] like Figures 1-11As shown, an open hollow terracotta panel curtain wall structure includes a terracotta panel 1, on which an aluminum alloy hanger 2 is fixedly installed; a keel steel frame 4, on which an aluminum alloy bracket 3 is fixedly installed, which is inserted and matched with the aluminum alloy hanger 2; the aluminum alloy bracket 3 includes a fixing part 33 connected to the keel steel frame 4, and an elongated hole 331 is formed on the fixing part 33 to adjust the front and rear position of the aluminum alloy bracket 3; and a fastener assembly 7, which is located on the top of the aluminum alloy hanger 2 and the aluminum alloy bracket 3 to adjust the vertical distance between the aluminum alloy hanger 2 and the aluminum alloy bracket 3.

[0024] Among them, there are at least two aluminum alloy hangers 2 located on the same horizontal line as the terracotta plate 1.

[0025] Specifically, the terracotta panel 1 and the keel steel frame 4 are connected by the plug-in cooperation between the aluminum alloy hanger 2 and the aluminum alloy bracket 3; Furthermore, the aluminum alloy bracket 3 adjusts the horizontal position relationship between the fixing part 33 and the keel steel frame 4 through the elongated hole 331, thereby indirectly adjusting the position of the terracotta plate 1 installed on the aluminum alloy bracket 3. Since aluminum alloy brackets 3 are provided at both the upper and lower positions of the same terracotta plate 1, adjusting the aluminum alloy brackets 3 at different positions at the top and bottom can ensure that the same terracotta plate 1 has good flatness. Similarly, the use of the aluminum alloy brackets 3 also makes the flatness between adjacent terracotta plates 1 consistent. Furthermore, after the aluminum alloy hanger 2 and the aluminum alloy bracket 3 are inserted and matched, since there are at least two aluminum alloy hangers 2 on the same horizontal line of the terracotta plate 1, by adjusting the fastener assembly 7 on the different aluminum alloy hangers 2 on the same horizontal line, the left and right sides of the terracotta plate 1 are not tilted, thus avoiding the situation of the terracotta plate 1 warping.

[0026] Compared to traditional terracotta panel curtain wall structures, this invention ensures the flatness of the same terracotta panel 1 and the consistent flatness between adjacent terracotta panels 1 by adjusting the horizontal distance between the aluminum alloy brackets 3 at different positions above and below and the keel steel frame 4. By adjusting the fastener assemblies 7 on different aluminum alloy hangers 2 on the same horizontal line, the terracotta panel 1 is prevented from tilting, thus avoiding the surface of the terracotta panel 1 from warping. The above adjustment steps are simple and few, making it convenient for practical applications.

[0027] This invention can fix the terracotta board 1 to the keel steel frame 4 by simply plugging in the aluminum alloy hanger 2 and the aluminum alloy bracket 3. Compared with bolt connection, it is easier to install, speeds up the construction progress, facilitates subsequent maintenance and replacement, and reduces maintenance costs.

[0028] Several hollow cavities 11 are arranged side by side along the length of the terracotta panel 1. Each hollow cavity 11 can accommodate a U-shaped aluminum connector 5. Each U-shaped aluminum connector 5 corresponds to an aluminum alloy hanger 2. Bolts pass through the aluminum alloy hanger 2, the terracotta panel 1, and the U-shaped aluminum connector 5 to connect the three. The U-shaped aluminum connector 5 can move along the hollow cavity 11, which facilitates the adjustment of the installation position of the aluminum alloy hanger 2 on the terracotta panel 1.

[0029] Specifically, the hollow cavity 11 of the terracotta panel 1 reduces its weight, making it easier to hang the terracotta panel 1 on the keel steel frame 4 and increasing the stability of the terracotta panel 1 hanging; while the aluminum alloy hanger 2, together with the U-shaped aluminum connector 5, is installed on the terracotta panel 1, ensuring the stability and adjustability of the installation of the aluminum alloy hanger 2.

[0030] The aluminum alloy pendant 2 includes a first pendant connecting part 21 and a second pendant connecting part 22; the aluminum alloy bracket 3 includes a first bracket connecting part 31 and a second bracket connecting part 32. The first bracket connecting part 31 is covered by the first pendant connecting part 21, and the second bracket connecting part 32 covers the second pendant connecting part 22, thus clarifying the insertion method between the aluminum alloy pendant 2 and the aluminum alloy bracket 3. The first bracket connecting part 31 and the second bracket connecting part 32 restrict the forward and backward movement of the first pendant connecting part 21 and the second pendant connecting part 22. That is, the insertion and engagement of the aluminum alloy pendant 2 and the aluminum alloy bracket 3 restricts the forward and backward movement of the terracotta plate 1 fixed on the aluminum alloy pendant 2.

[0031] A hanging bend 221 is formed on the second hanging connector 22, and a bracket bend 311 is formed on the first bracket connector 31. The bottom of the first hanging connector 21 is opposite to the bracket bend 311, and the top of the second bracket connector 32 is opposite to the hanging bend 221. That is, the bracket bend 311 abuts against the bottom of the first hanging connector 21, and the top of the second bracket connector 32 abuts against the hanging bend 221. The insertion and engagement of the aluminum alloy hanging piece 2 and the aluminum alloy bracket 3 restricts the downward movement of the aluminum alloy hanging piece 2, and thus restricts the downward movement of the terracotta plate 1 fixed on the aluminum alloy hanging piece 2.

[0032] The aluminum alloy bracket 2 also includes an abutment part 23, which connects the first bracket connection part 21 and the second bracket connection part 22. The abutment part 23 abuts against the terracotta plate 1 to facilitate the bolt passing through the abutment part 23, the terracotta plate 1, and the U-shaped aluminum connector 5 to achieve the connection of the three.

[0033] The fastener assembly 7 includes a first fastener 71 and a second fastener 72. The first fastener 71 passes through the first hanger connecting part 21 and the first bracket connecting part 31 to connect the aluminum alloy hanger 2 and the aluminum alloy bracket 3. The second fastener 72 passes through the first hanger connecting part 21 and abuts against the first bracket connecting part 31 to control the vertical distance between the aluminum alloy hanger 2 and the aluminum alloy bracket 3. The first fastener 71 is preferably a self-tapping screw, and the second fastener 72 is preferably a bolt.

[0034] Specifically, the insertion and engagement of the aluminum alloy hanger 2 and the aluminum alloy bracket 3 restricts the forward and backward movement and downward movement of the aluminum alloy hanger 2. Consequently, the terracotta plate 1 installed on the aluminum alloy hanger 2 is also restricted from moving forward and backward and downward. Furthermore, the first fastener 71 connects the aluminum alloy hanger 2 and the aluminum alloy bracket 3, achieving a more stable connection between them. The second fastener 72, located on one side of the first fastener 71, passes through the first hanger connection part 21 and abuts against the top of the first bracket connection part 31. When the second fastener 72 is tightened downwards, the vertical distance between the aluminum alloy hanger 2 and the aluminum alloy bracket 3 increases. Consequently, the terracotta plate 1 moves upward relative to the keel steel frame 4, adjusting the vertical distance between the terracotta plate 1 and the keel steel frame 4.

[0035] The present invention defines the lowest position of the terracotta plate 1 in the keel steel frame 4 by the first hanging part 21 and the second hanging part 22 of the aluminum alloy hanging part 2 and the first code base connecting part 31 and the second code base connecting part 32 of the aluminum alloy code base 3. When the fastener assembly 7 controls the vertical distance between the aluminum alloy hanging part 2 and the aluminum alloy code base 3, the vertical distance between the terracotta plate 1 and the keel steel frame 4 will be adjusted to ensure that the terracotta plate 1 does not tilt.

[0036] The first fastener 71 in the fastener assembly 7 of the present invention also serves to fasten the aluminum alloy hanger 2 and the aluminum alloy bracket 3, and plays a role in preventing jumping and limiting the position of the terracotta plate 1 after installation, thus ensuring the stability of the terracotta plate 1.

[0037] The keel steel frame 4 includes a steel frame 41 and a steel square tube 42. The steel frame 41 includes a mounting base 411, and a first latch 4111 is formed on the top of the mounting base 411. The steel square tube 42 includes a steel plate 421, and a second latch 4211 is formed on the steel plate 421 to engage with the first latch 4111. Bolt fixing plates for fixing bolts can also be installed on both sides of the steel plate 421. When the first latch 4111 and the second latch 4211 are engaged, adjusting the bolts on both sides of the steel plate 421 can control the vertical position relationship between the steel frame 41 and the steel square tube 42.

[0038] An angle steel 422 is provided on the side of the steel square tube 42 facing the terracotta plate 1, and an aluminum alloy bracket 3 is installed on the angle steel 422. The angle steel 422 facilitates the installation and adjustment of the aluminum alloy bracket 3.

[0039] Specifically, the keel steel frame 4 is divided into two components: steel frame 41 and steel square tube 42, which makes the form of the keel steel frame 4 more diversified, and consequently, the terracotta panel curtain wall indirectly installed on the keel steel frame 4 is also more diversified.

[0040] A waterproof membrane 6 is also provided between the keel steel frame 4 and the main structure. The waterproof membrane 6 is preferably a waterproof aluminum plate, which prevents rainwater from seeping into the main structure.

[0041] The waterproof membrane 6 of this invention can effectively prevent rainwater from penetrating the main structure and improve the service life of the terracotta panel curtain wall structure.

[0042] An installation method for an open-type hollow terracotta panel curtain wall structure, including... Step 1: Install a waterproof membrane 6 between the main building structure and the keel steel frame 4. The steel frame 41 and steel square tube 42 of the keel steel frame 4 are connected by a first snap-fit ​​4111 and a second snap-fit ​​4211. Step 2: The bolt passes through the angle steel 422 of the square tube 42 and the elongated hole 331 of the fixing part 33 and is locked by the nut to realize the installation of the aluminum alloy bracket 3 on the square tube 42. Step 3: The bolt passes through the aluminum alloy hanger 2, the terracotta plate 1 and the U-shaped aluminum connector 5 and is locked by the nut to realize the installation of the aluminum alloy hanger 2 on the terracotta plate 1; Step 4: The aluminum alloy pendant 2 and the aluminum alloy bracket 3 are inserted and matched. The bottom of the first pendant connecting part 21 is opposite to the bent part 311 of the bracket, and the top of the second bracket connecting part 32 is opposite to the bent part 221 of the pendant. Step 5: The first fastener 71 passes through the first pendant connecting part 21 and the first code base connecting part 31 to connect the aluminum alloy pendant 2 and the aluminum alloy code base 3. The second fastener 72 passes through the first pendant connecting part 21 and abuts against the first code base connecting part 31, thereby controlling the vertical distance between the aluminum alloy pendant 2 and the aluminum alloy code base 3.
