Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a wind-proof and wind-vibration-resistant open ceiling construction method and an installation structure thereof. Background Art

[0002] The ceiling design and installation were conducted for the unique spatial form of the east-west corridor. The left side of this area features a full-height, enclosed glass curtain wall system, while the right side features a 1.2m-high stainless steel railing viewing platform, creating a semi-open building interface. CFD wind tunnel simulation analysis revealed that this unique structure results in the following lateral wind pressure characteristics:

[0003] 1. During the windy season every year, strong winds blowing from the southeast will quickly flow in through the gap in the right viewing platform area like a "through draft". The wind speed at this location will be about 30% faster than normal.

[0004] 2. At the corner where the glass curtain wall and the ceiling meet, a dynamic negative pressure zone is generated in the transition area, which will suck the ceiling upwards. The maximum suction force can reach 0.8-1.2kPa, which is equivalent to the weight of two adults standing on each standard panel (2800×1500).

[0005] 3. The aluminum panel system must withstand the upward wind load of a Class II site with a 50-year recurrence period (standard value 0.65kN / m²). The upward pull force generated in extreme weather conditions is equivalent to hanging a 65kg weight on each square meter of aluminum panel. Summary of the Invention

[0006] In order to solve the problem of suspended ceilings in special spaces with the above special conditions, the present invention proposes a windproof and wind-vibration-resistant open suspended ceiling construction method and an installation system thereof.

[0007] A method for constructing an open ceiling that is windproof and wind-vibration-resistant, comprising the following steps:

[0008] Step 1. Measure and set out: Mark a +1000mm horizontal point on the wall or column corner in the corridor, pop up a level line, measure from the level line to the designed ceiling height plus the thickness of the aluminum plate and the height of the folded edge, and use a chalk line to pop up the bottom edge of the ceiling transition layer and the finished surface elevation of the aluminum plate ceiling along the wall or column;

[0009] Step 2: Construction of transfer layer: Re-measure the bottom elevation of the electromechanical pipelines, use galvanized angle steel for horizontal, vertical, and longitudinal welding, with spacing of ≤1200mm. When encountering electromechanical main pipelines, the spacing is increased to ≤900mm, and the transfer layer is set. The top of the galvanized angle steel is embedded in the structural top plate with chemical anchor bolts;

[0010] Step 3: Install the multi-cavity special-shaped keel: Determine the installation spacing of the multi-cavity special-shaped keel according to the width of the aluminum plate, ensure that the edge of each aluminum plate is supported by the multi-cavity special-shaped keel, and use the bolt group to fix the multi-cavity special-shaped keel on the transfer layer. The bolt group spacing is ≤ 600mm;

[0011] Step 4. Install interlocking hangers: Pre-install 4 sets of interlocking hangers on each aluminum plate. Each set of interlocking hangers consists of 2 interlocking hangers, and each set of interlocking hangers is arranged at a spacing of ≤600mm. The 2 interlocking hangers are symmetrically pre-embedded in the prefabricated grooves on the back of the aluminum plate. The two sides of the multi-cavity special-shaped keel are respectively inserted into the 2 interlocking hangers to ensure that the surfaces of the two adjacent aluminum plates are flush.

[0012] Step 5: Install the windproof reinforcement system. Install box-type windproof pressure plates along the center line of the gap between each two aluminum plates. The box-type windproof pressure plates are fixed to the multi-cavity special-shaped keel with countersunk screws. The box-type windproof pressure plates are locked to the multi-cavity special-shaped keel with countersunk screws arranged at intervals of ≤600mm. The overlap length between the box-type windproof pressure plates and the aluminum plates is ≥50mm.

[0013] Step 6. Finishing node processing: Perform finishing node processing on the finished surface of the cylinder, the finished surface of the rhombus column, and the finished surface of the curtain wall aluminum veneer and the aluminum plate.

[0014] Furthermore, in step 2, a total station is used to re-measure the bottom elevation of the electromechanical pipeline, and the galvanized angle steel is L50×5 galvanized angle steel.

[0015] Furthermore, in step 3, the bolts are M8 bolt sets. After all keels are installed, the keel elevation is verified using a laser level. The horizontal deviation of a single keel per span is ≤3mm, and the cumulative deviation of the entire installed keel is ≤5mm / 30m.

[0016] Furthermore, in step 5, the countersunk screws are M6 stainless steel countersunk screws. The upper end of the box-shaped windbreak pressure plate is fixed to the multi-cavity special-shaped keel with the M6 ​​stainless steel countersunk screws. The lower end of the box-shaped windbreak pressure plate is inserted into the gap between the adjacent aluminum plates. After the box-shaped windbreak pressure plate is installed, it is tested using a wind speed simulator to ensure that the aluminum plate surface displacement is ≤3mm under a wind pressure of 1.5kPa and there are no abnormal sounds.

[0017] Furthermore, in step 6, the finished surface of the cylinder is 20mm away from the aluminum plate ceiling, and a 1.2mm thick 50*12mm curved edging strip is used for edging. The finished surface of the oblique column is 20mm away from the aluminum plate ceiling, and a 1.2mm thick 29*12mm U-shaped edging strip is used for edging. The finished surface of the curtain wall aluminum veneer is 15mm away from the honeycomb aluminum plate ceiling. A 3mm thick aluminum strip is fixed on the curtain wall aluminum veneer, and a 4.20*20*3mm angle code is fixed on the side of the honeycomb aluminum plate. After fixing the aluminum strip and the angle code with screws, a plastic strip is installed at the 15mm gap, and a 10mm gap is left on the edge of the aluminum plate at the step.

[0018] The second technical solution provided by the present invention is:

[0019] A semi-open ceiling installation structure that is windproof and wind-vibration-resistant, includes a multi-cavity special-shaped keel, an interlocking hanger, a box-type windproof pressure plate and an aluminum plate. The top of the multi-cavity special-shaped keel is fixedly connected to the galvanized angle steel of the conversion layer, the lower end of the multi-cavity special-shaped keel is fixedly connected to the upper end of the box-type windproof pressure plate by a countersunk screw, the lower end of the box-type windproof pressure plate is clamped into the gap between two adjacent aluminum plates and fixedly connected, the upper ends of the two interlocking hangers are symmetrically clamped and connected to the two ends of the multi-cavity special-shaped keel, and the lower ends of the two interlocking hangers are symmetrically embedded in the prefabricated grooves of the two adjacent aluminum plates.

[0020] Furthermore, the multi-cavity special-shaped keel is integrally formed, including upper and lower flanges and a middle vertical rib. The upper flange, two middle vertical ribs and lower flange are fixedly connected in an I-shape. The middle disconnected portion of the upper flange moves downward to form a square groove in which the lower upper flange is connected to the two middle vertical ribs. The middle position of the lower flange protrudes upward to form a trapezoidal groove. Two end vertical ribs are provided at both ends of the lower flange. The two end vertical ribs are respectively fixedly connected to two bite-type hangers. The square groove is fixedly connected to the galvanized angle steel of the conversion layer by an M8 bolt group, and the trapezoidal groove is fixedly connected to the box-type windproof pressure plate by an M6 stainless steel countersunk screw.

[0021] Furthermore, the bite-type hanger includes an upper eagle-beak hook-shaped bite claw, a middle multi-bend vertical part and a lower horizontal part at the lower end. The eagle-beak hook-shaped bite claw, the multi-bend vertical part and the lower horizontal part are integrally formed, the end vertical rib is clamped into the eagle-beak hook-shaped bite claw for fixed connection, and the lower horizontal part is embedded in the prefabricated groove of the aluminum plate.

[0022] Furthermore, the box-shaped windproof pressure plate is integrally compression-molded, including horizontal parts on both sides, vertical parts at both ends and a box-shaped part. The upper ends of the vertical parts at both ends are fixedly connected to one end of the horizontal parts on both sides, and the lower ends of the vertical parts at both ends are respectively inserted into the prefabricated grooves of the aluminum plates. The other ends of the horizontal parts on both sides are respectively fixedly connected to the middle parts of the two ends of the box-shaped part. The upper part of the box-shaped part is fixedly connected to the trapezoidal groove by M6 stainless steel countersunk screws, and the lower part of the box-shaped part is inserted into the gap between two adjacent aluminum plates. The lengths of the horizontal parts on both sides are the same, 18mm<the length of the horizontal parts on both sides<20mm, and the aluminum plate is a metal honeycomb aluminum plate.

[0023] The beneficial effects of the present invention are:

[0024] (1) The present invention has been verified by wind tunnel tests. Under the simulated wind speed of 42m / s, the maximum displacement of the aluminum plate surface is only 2.3mm (less than the L / 200 limit in the specification), which solves the problem of wind vibration control in semi-open ceiling systems.

[0025] (2) The present invention adopts a box-type windproof pressure plate throughout the entire length. The box-type windproof pressure plate is fixed to the multi-cavity special-shaped keel by arranging M6 stainless steel countersunk screws at a spacing of 600mm to form a continuous wind pressure-resistant strip, which can effectively decompose 80% of the wind suction force;

[0026] (3) The cross section of the multi-cavity special-shaped keel in the present invention is a multi-cavity special-shaped structure. The multi-cavity structure forms a continuous force transmission path, effectively decomposing the hanging and wind resistance capabilities. The upper flange, two middle vertical ribs and the lower flange are fixedly connected in an I-shape to improve the bending resistance. The middle position of the lower flange protrudes upward to form a trapezoidal groove, which is convenient for locking the box-type windproof pressure plate and the multi-cavity special-shaped keel, thereby improving the windproof performance.

[0027] (4) The interlocking hanger of the present invention adopts a composite interlocking cross-section, and realizes high-strength load transfer through a multi-directional force-bearing structure;

[0028] (5) The box-type wind-proof pressure plate in the present invention adopts a multi-level bending-resistant section. The middle box-type structure improves the torsion resistance. The upper part of the box body provides a structure for the locking connection between the wind-proof pressure plate and the keel. The lower part of the box body is inserted into the gap between two aluminum plates. The contact length between the flanges on both sides and the aluminum plates is ≥50mm, which disperses the stress of the screw nodes in the connection between the wind-proof pressure plate and the keel and increases the wind pressure resistance.

[0042] A method for constructing a semi-open suspended ceiling that is wind-proof and wind-vibration-resistant comprises the following steps:

[0043] Step 1. Measure and set out: Mark a +1000mm horizontal point on the wall or column corner in the corridor, pop up a level line, measure from the level line to the designed ceiling height plus the thickness of the aluminum plate and the height of the folded edge, and use a chalk line to pop up the bottom edge of the ceiling transition layer and the finished surface elevation of the aluminum plate ceiling along the wall or column;

[0044] Step 2: Construction of transfer layer: Re-measure the bottom elevation of the electromechanical pipelines, use galvanized angle steel for horizontal, vertical, and longitudinal welding, with spacing of ≤1200mm. When encountering electromechanical main pipelines, the spacing is increased to ≤900mm, and the transfer layer is set. The top of the galvanized angle steel is embedded in the structural top plate with chemical anchor bolts;

[0045] Furthermore, in step 2, a total station is used to re-measure the bottom elevation of the electromechanical pipeline, and the galvanized angle steel is L50×5 galvanized angle steel.

[0046] Step 3: Install the multi-cavity special-shaped keel: Determine the installation spacing of the multi-cavity special-shaped keel according to the width of the aluminum plate, ensure that the edge of each aluminum plate is supported by the multi-cavity special-shaped keel, and use the bolt group to fix the multi-cavity special-shaped keel on the transfer layer. The bolt group spacing is ≤ 600mm;

[0047] Furthermore, in step 3, the bolt group is an M8 bolt group. After all the multi-cavity special-shaped keels are installed, the elevation of the multi-cavity special-shaped keels is checked using a laser level. The horizontal deviation of a single multi-cavity special-shaped keel in a single span is ≤3mm, and the cumulative deviation of the entire multi-cavity special-shaped keel after installation is ≤5mm / 30m.

[0048] Step 4. Install interlocking hangers: Pre-install 4 sets of interlocking hangers on each aluminum plate. Each set of interlocking hangers consists of 2 interlocking hangers, and each set of interlocking hangers is arranged at a spacing of ≤600mm. The 2 interlocking hangers are symmetrically pre-embedded in the prefabricated grooves on the back of the aluminum plate. The two sides of the multi-cavity special-shaped keel are respectively inserted into the 2 interlocking hangers to ensure that the surfaces of the two adjacent aluminum plates are flush.

[0049] Step 5: Install the windproof reinforcement system. Install box-type windproof pressure plates along the center line of the gap between each two aluminum plates. The box-type windproof pressure plates are fixed to the multi-cavity special-shaped keel with countersunk screws. The box-type windproof pressure plates are locked to the multi-cavity special-shaped keel with countersunk screws arranged at intervals of ≤600mm. The overlap length between the box-type windproof pressure plates and the aluminum plates is ≥50mm.

[0050] Furthermore, in step 5, the countersunk screws are M6 stainless steel countersunk screws, and the upper end of the box-type windproof pressure plate is fixedly connected to the multi-cavity special-shaped keel by M6 stainless steel countersunk screws. The lower end of the box-type windproof pressure plate is inserted into the gap between the adjacent aluminum plates. After the box-type windproof pressure plate is installed, a wind speed simulator is used for testing to ensure that the aluminum plate surface displacement is ≤3mm under a wind pressure of 1.5kPa and there is no abnormal sound.

[0051] Step 6. Finishing node processing: Perform finishing node processing on the finished surface of the cylinder, the finished surface of the rhombus column, and the finished surface of the curtain wall aluminum veneer and the aluminum plate.

[0052] Furthermore, in step 6, the finished surface of the cylinder is 20mm away from the aluminum plate ceiling, and a 1.2mm thick 50*12mm curved edging strip is used for edging. The finished surface of the oblique column is 20mm away from the aluminum plate ceiling, and a 1.2mm thick 29*12mm U-shaped edging strip is used for edging. The finished surface of the curtain wall aluminum veneer is 15mm away from the honeycomb aluminum plate ceiling. A 3mm thick aluminum strip is fixed on the curtain wall aluminum veneer, and a 4.20*20*3mm angle code is fixed on the side of the honeycomb aluminum plate. After fixing the aluminum strip and the angle code with screws, a plastic strip is installed at the 15mm gap, and a 10mm gap is left on the edge of the aluminum plate at the step.

[0053] The construction of suspended ceilings in special semi-open spaces such as east-west corridors requires solving the problems of being able to withstand higher wind speeds than ordinary suspended ceilings, as well as the problem of the suspended ceiling being adsorbed and generating extraordinary loads. In order to be able to carry out suspended ceiling construction in this special semi-open space, the present invention designs multi-cavity special-shaped keels, interlocking hangers, and box-type windproof pressure plates. In the installation method, the box-type windproof pressure plates are locked to the multi-cavity special-shaped keels by countersunk screws, the box-type windproof pressure plates are inserted into two adjacent aluminum plates, the multi-cavity special-shaped keels are symmetrically connected to the two interlocking hangers, and the two interlocking hangers are embedded in the prefabricated grooves of the aluminum plates, thereby improving the windproof, load-resistant and wind-vibration-resistant performance of the suspended plates. This solves the problem of installing windproof and wind-vibration-resistant high-load suspended ceilings in special semi-open spaces.

[0054] The present invention also discloses a semi-open ceiling installation structure that is windproof and wind-vibration-resistant, such as Figures 1 to 5 As shown, it includes a multi-cavity special-shaped keel 1, an interlocking hanger 2, a box-type windproof pressure plate 3 and an aluminum plate 4. The top of the multi-cavity special-shaped keel 1 is fixedly connected to the galvanized angle steel 5 of the conversion layer by a bolt group 7, the lower end of the multi-cavity special-shaped keel 1 is fixedly connected to the upper end of the box-type windproof pressure plate 3 by a countersunk screw 6, and the lower end of the box-type windproof pressure plate 3 is clamped into the gap between two adjacent aluminum plates 4 and fixedly connected. The upper ends of the two interlocking hangers 2 are symmetrically clamped and connected to the two ends of the multi-cavity special-shaped keel 1, and the lower ends of the two interlocking hangers 2 are symmetrically embedded in the prefabricated grooves of the two adjacent aluminum plates 4. This installation system uses countersunk screws 6 to lock the box-type windproof pressure plate 3 on the multi-cavity special-shaped keel 1 and the lower end of the box-type windproof pressure plate 3 is inserted into the gap of the adjacent aluminum plates 4, thereby improving the windproof performance of the ceiling. After the lower ends of the two interlocking hangers 2 are symmetrically embedded in the prefabricated grooves of the two adjacent aluminum plates 4, the upper ends of the two interlocking hangers 2 are symmetrically connected to the two ends of the multi-cavity special-shaped keel 1. The symmetrical interlocking connection and the symmetrical embedding of the aluminum plates significantly improve the wind vibration resistance and load capacity of the hangers.

[0055] Further, if Figure 3As shown, the multi-cavity special-shaped keel 1 is integrally formed, including an upper flange 11, a lower flange 12 and a middle vertical rib 13. The upper flange 11, the two middle vertical ribs 13 and the lower flange 12 are fixedly connected to form an I-shape. The middle disconnected part of the upper flange 11 moves downward to form a square groove 14 in which the lower upper flange is connected to the two middle vertical ribs. The middle position of the lower flange protrudes upward to form a trapezoidal groove 15. Two end vertical ribs 16 are provided at both ends of the lower flange. The two end vertical ribs 16 are respectively fixedly connected to two bite-type hangers 2. The square groove 14 is fixedly connected to the galvanized angle steel of the conversion layer by an M8 bolt group, and the trapezoidal groove is fixedly connected to the box-type windproof pressure plate by an M6 stainless steel countersunk screw 6. The multi-chamber structure creates a continuous force transmission path, effectively reducing installation and wind resistance. The upper flange 11, two middle vertical ribs 13, and lower flange 12 are fixedly connected in an I-shape to enhance bending resistance. A trapezoidal groove 15 protrudes upward from the center of the lower flange to facilitate screwing the windproof pressure plate. In this embodiment, the dimensions of the trapezoidal groove 15 are 11*7*4.

[0056] Further, if Figure 4 As shown, the snap-fit ​​hanger 2 includes an upper hawk's beak hook-shaped snapping claw 21, a middle multi-bend vertical portion 22, and a lower horizontal portion 23. These claws 21, multi-bend vertical portion 22, and lower horizontal portion 23 are integrally formed. The end vertical rib 16 is snapped into the hook-shaped snapping claw 21 for secure connection, while the lower horizontal portion 23 is embedded in a prefabricated groove in the aluminum plate 4. The upper hook-shaped snapping claw 21 fits into the end vertical rib slot of the multi-cavity special-shaped keel 1, bearing vertical tension. The 21mm horizontal portion 23 at the lower end fits perfectly into the U-shaped groove reserved at the edge of the aluminum plate, allowing for multi-directional locking in vertical, horizontal, and torsional directions to meet the requirements of high-load, high-wind pressure, and complex environments.

[0057] Further, if Figure 5 As shown, the box-shaped windproof pressure plate 3 is integrally compression-molded, including horizontal parts 31 on both sides, vertical parts 32 at both ends and a box-shaped part 33. The upper ends of the vertical parts 32 at both ends are fixedly connected to one end of the horizontal parts 31 on both sides, and the lower ends of the vertical parts 32 at both ends are respectively inserted into the prefabricated grooves of the aluminum plates. The other ends of the horizontal parts 31 on both sides are respectively fixedly connected to the middle parts of the two ends of the box-shaped part 33. The upper part 331 of the box-shaped part is fixedly connected to the trapezoidal groove 15 by an M6 stainless steel countersunk screw 6. The lower part 332 of the box-shaped part is inserted into the gap between the two adjacent aluminum plates 4. The horizontal parts 32 on both sides have the same length, 18mm<the length of the horizontal parts on both sides<20mm, and the aluminum plate 4 is a metal honeycomb aluminum plate. The box-shaped structure of the box-shaped part 33 improves the torsion resistance. The upper part 331 of the box body satisfies the function of locking with M6 screws, and the lower part 332 of the box body assists in inserting into the gap between adjacent aluminum plates. The gap between adjacent aluminum plates is controlled to correspond to the size of the lower part 332 of the box body. The horizontal parts on both sides increase the contact area with the aluminum plate, disperse the stress of the bolt nodes, and increase the wind pressure resistance.

[0058] It should be noted that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that various modifications, equivalent substitutions, and variations may be made to the present invention. However, as long as these modifications do not depart from the spirit of the present invention, they are intended to be within the scope of protection of the present invention.
