Description

Technical Field

[0001] The present invention belongs to the technical field of curtain walls, and relates to a three-dimensional adjustable daylighting roof curtain wall system adapted to a three-dimensional space and a construction method thereof. Background Art

[0002] With the diversification of building forms, glass daylighting roofs with special-shaped curved surfaces are becoming more and more common. For traditional glass daylighting roofs, the common practice is to directly install glass on the steel frame, and at the places with curved surface shapes, only pads or special-shaped bars folded from aluminum plates are used for assembly; this kind of curtain wall system has a complex structure, many joints, great construction difficulty, and a relatively high potential for water leakage; the displacement caused by thermal expansion and contraction between the plates causes the sealant to crack, and the opening and closing of the joints affect the external finish effect. For the above reasons, it is very difficult to guarantee the construction quality, which has an adverse impact on the use and later maintenance of the glass daylighting roof. The present invention comprehensively considers various adverse factors that may be encountered in the project from the early stage of design, and invents a three-dimensional adjustable structure in a three-dimensional space, which can eliminate the adverse effects of the glass daylighting roof in construction and later maintenance to the greatest extent, guarantee the construction quality, reduce the later maintenance difficulty, and bring a new visual experience to the customers. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a daylighting roof curtain wall system adapted to a three-dimensional space with a high degree of prefabrication, safety and reliability, simple structure, easy processing, convenient construction, a large construction error adjustment ability, which can greatly improve the construction quality and meet diverse shapes.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A three-dimensional adjustable daylighting roof curtain wall system adapted to a three-dimensional space includes main keels and secondary keels that cross each other. The daylighting roof curved glass is installed on the same side of the main keels and secondary keels. A glass pressing plate is arranged outside the daylighting roof curved glass to fix the daylighting roof curved glass. The main keels and secondary keels are connected by cross beam connectors. The secondary keels are symmetrically distributed on both sides of the main keels. Fastener four fixes and connects the main keel and the main keel adjustment member below it. The connection holes of fastener four and the two are oblong holes. The support arm of the main keel adjustment member and the support arm of the main keel base below it are adjusted and fixed in height through a vertical oblong hole. The main keel base and the steel base below it are fixedly connected through an oblong hole in the left-right direction.

[0006] Further, fastener four is a bolt. The lower part of the main keel is an arc structure. Two bolt slots for holding the bolt head are arranged at the bottom of the main keel. The upper end of the main keel adjustment member is an arc part that matches the main keel, and the oblong hole is opened on the arc part.

[0007] Further, teeth that cooperate with each other are respectively provided on the arc portions of the main keel and the main keel adjusting fitting.

[0008] Further, the bottom of the curved glass of the daylighting roof is fixed to the secondary frame. The pressing blocks are fixedly connected to the upper end surface of the secondary keel at intervals through fasteners five. The cross beam connecting member and the main keel are fixedly connected through fasteners one. The secondary keel is sleeved on the cross beam connecting member and fixedly connected through self-tapping screws. The part where the cross beam connecting member contacts the main keel is an arc-shaped groove that cooperates with the main keel. A circumferential oblong hole is opened in the arc-shaped groove. A bolt notch for placing the bolt head is provided on the main keel. The fasteners one fix the cross beam connecting member and the main keel through the oblong hole.

[0009] Further, the secondary keel cover is longitudinally snap-connected to the secondary keel.

[0010] Further, the main keel and the secondary keel support the curved glass of the daylighting roof through ethylene propylene diene monomer rubber strip one and ethylene propylene diene monomer rubber strip two. The glass pressing plate presses the ethylene propylene diene monomer rubber strip one between the glass pressing plate and the curved glass of the daylighting roof through fasteners. One end of the curved glass of the daylighting roof is located between the ethylene propylene diene monomer rubber strip one and the ethylene propylene diene monomer rubber strip two on the same side. The ethylene propylene diene monomer rubber strip two is located between the secondary keel and the curved glass of the daylighting roof.

[0011] Further, gaskets are placed between the main keel base and the steel base below it.

[0012] Further, a decorative cover is assembled on the glass pressing plate.

[0013] A construction method for a three-dimensional adjustable daylighting roof curtain wall system adapted to a three-dimensional space includes the following steps:

[0014] (1) Preparation: Pre-measure the main steel frame, perform three-dimensional positioning on the positions of each fixed support, and mark the positions;

[0015] (2) Frame assembly: Bond and fix the secondary frame to both sides of the curved glass of the daylighting roof, and store and cure it according to the design requirements to ensure the bonding strength for the assembled installation at the construction site;

[0016] (3) Layout and establishment of the skeleton support: Perform precise layout on the main steel frame, and pre-weld the steel base to the main steel frame after processing it according to the measured dimensions;

[0017] (4) Installation of the base: Connect the main keel base to the position of the steel base, ensure the connection is in place, and temporarily do not fasten it firmly;

[0018] (5) On-site skeleton assembly: The main keel and the secondary keel are connected and fixed through the cross beam connecting member, and are assembled and spliced into an integral keel framework in blocks according to the design drawings. The main keel adjusting fitting is also pre-assembled to the integral keel framework at the established position;

[0019] (6) On-site assembly: Lift and install the assembled integral dragon skeleton according to the on-site numbering. After hoisting in place, adjust the main keel adjustment fittings and the main keel base on-site until they are in place, and fasten and connect them with fastener two. When all connection points are connected and fixed in place to meet the design requirements, then fasten and lock all the fasteners. After the integral dragon skeleton is installed and fastened, install the curved glass of the daylighting roof. The glass and the profiles are directly pressed, isolated, and supported by ethylene propylene diene monomer (EPDM) rubber strip one and EPDM rubber strip two. The glass pressing plates are fixed and connected at certain intervals with fastener six to press and fix the glass. Finally, snap the decorative cover onto the glass pressing plates.

[0020] Furthermore, the upper and lower edges of the curved glass of the daylighting roof in the exposed frame part are sealed with two rubber strips. Before the construction of the glass pressing plates, after the curved glass of the daylighting roof is installed on the main keel, sealant is applied at the connection gap position; in the hidden frame part, sealant is directly applied at the glass gap; the decorative covers are arranged in the drainage direction.

[0021] The beneficial effects of the present invention are as follows:

[0022] The entire keel adjustment system of the present invention is matched and connected in the form of aluminum alloy die-cast components, with high fitting degree and firm connection. The bolt heads are all hidden in the slots of the keel, with firm clamping and not easy to fall off or slide. Both the connection gasket and the rotating mechanism have a toothed mechanism, and are automatically clamped and positioned during the bolt tightening process;

[0023] The present invention avoids the problems of loosening of connecting parts and sliding of gaskets in steel part connections, effectively avoids damage to finished parts during on-site welding, and ensures connection safety;

[0024] The aluminum alloy keel of the present invention is simple to process and can be bent arbitrarily according to the shape of the daylighting roof. There is enough space between the glass and the keel to meet the mutual displacement and dislocation. The connection structure can achieve rotational connection at any angle between the keels. The structure is simple, and the keels can be integrally spliced and installed in different areas, greatly simplifying the construction cost and providing good technical support for realizing prefabricated construction;

[0025] All the connecting components of the present invention can be processed in the factory, with high mechanization degree, easy control of processing accuracy, simple installation construction, high efficiency, improving the construction quality while saving labor costs.

[0048] As shown in the figure, a three-dimensional adjustable daylighting roof curtain wall system adapted to a three-dimensional space includes a cross-shaped skeleton and a curved glass 1 for daylighting roof installed on the skeleton. A glass pressing plate 5 is provided on the outer side of the glass to fix the curved glass 1 for daylighting roof, and a decorative cover 4 is assembled on the glass pressing plate 5.

[0049] The framework is of a frame structure and is formed by connecting the main keel 2 made of aluminum alloy and the secondary keel 3 made of aluminum alloy through a crossbeam connecting piece 11. The secondary keels 3 are symmetrically distributed on both sides of the main keel 2. The main keel 2 and the secondary keel 3 support the curved daylighting top glass 1 through an EPDM rubber strip one 12 and an EPDM rubber strip two 19. The glass pressing plate 5 presses the EPDM rubber strip one 12 between the glass pressing plate 5 and the curved daylighting top glass 1 through a fastener six 23. The end of the curved daylighting top glass 1 is located between the EPDM rubber strip one 12 and the EPDM rubber strip two 19 on the same side. The EPDM rubber strip two 19 is located between the secondary keel 3 and the curved daylighting top glass 1.

[0050] The lower part of the main keel 2 is circular. Two bolt notches for placing the bolt heads are provided at the bottom of the main keel 2. A circumferential oblong hole is provided on the main keel adjusting member 6. The main keel 2 is fixedly connected to the main keel adjusting member 6 below it through the oblong hole by a fastener four 18. The main keel adjusting member 6 includes a support arm and an arc portion at its upper end that cooperates with the main keel 2. The oblong hole is opened on the arc portion. A fixing mechanism for the main keel 2 to rotate relative to the main keel adjusting member 6 is realized by setting the circumferential oblong hole. Teeth that cooperate with each other are respectively provided on the arc portions of the main keel 2 and the main keel adjusting member 6.

[0051] The height adjustment and fixation between the support arm of the main keel adjusting member 6 and the support arm of the main keel base 7 below it are realized through a vertical oblong hole; the fastener two 16 fixes the support arm of the main keel adjusting member 6 and the support arm of the main keel base 7. Teeth that cooperate with each other are respectively provided on the support arms of the main keel adjusting member 6 and the main keel base 7. Since the main keel base 7 and the steel base 8 below it are made of different materials, a gasket 9 is placed between them to avoid bimetallic corrosion. The main keel base 7 realizes the rotational adjustment and fixation relative to the steel base 8 in the xy plane through the oblong holes in the left - right direction at the front and rear ends, and the main keel base 7 is fixed to the steel base 8 through a fastener three 17. The steel base 8 and the main body steel frame 10 below it are fixedly connected by welding.

[0052] The curved glass 1 of the daylighting roof with hidden frame edges is fixed to the upper end face of the upper connecting plate of the secondary frame 22 made of aluminum alloy through structural adhesive. The pressing block 21 made of aluminum alloy is fixedly connected to the secondary keel 3 at a certain interval through the fastener five 20. The lower connecting plate of the secondary frame 22 is clamped by the pressing block 21 on the secondary keel 3. The cross beam connecting piece 11 and the main keel 2 are fixedly connected through the fastener one 13. The secondary keel 3 is sleeved on the cross beam connecting piece 11 and fixedly connected through self-tapping screws 14. After the end connection is fixed, the secondary keel cover 15 is longitudinally buckled on the secondary keel 3 to cover all the nail heads. The part where the cross beam connecting piece 11 contacts the main keel 2 is an arc groove matching with the main keel 2. A circumferential long round hole is opened in the arc groove. A bolt notch for placing the bolt head is arranged on the main keel 2. The fastener one 13 fixedly connects the cross beam connecting piece 11 and the main keel 2 through the long round hole.

[0053] The main keel adjusting code piece 6 is processed with a long round hole in the x direction. The rotation effect in the xz plane is generated by the movement of the fastener four 18 in the long round hole. The main keel 2 is fixedly connected to the main keel adjusting code piece 6 through two fasteners four 18 at the bottom to meet the requirements of the rotating shape of the daylighting roof.

[0054] The two ends of the base of the main keel base 7 are processed with long round holes. The rotation in the xy plane is generated by the movement of the long round holes. After the adjustment and positioning, it is fixedly fastened through the fastener three 17. This mechanism can meet the requirements of the rotating shape of this set of systems at a certain angle in the xy direction.

[0055] The specific construction method of the daylighting roof curtain wall system adapted to three-dimensional adjustment in the three-dimensional space mainly includes the following steps:

[0056] (1) Preparation: The main steel frame 10 is measured in advance, and the positions of each fixed support are three-dimensionally positioned and marked.

[0057] (2) Frame assembly: The secondary frame 22 made of aluminum alloy is bonded and fixed to both sides of the curved glass 1 of the daylighting roof with silicone structural adhesive, and stored and cured according to the design requirements to ensure the bonding strength, which is convenient for the assembly installation at the construction site.

[0058] (3) Layout and establishment of the skeleton support: Precise layout is carried out on the main steel frame 10, and the steel base 8 is pre-welded on the main steel frame 10 after being processed according to the measured dimensions.

[0059] (4) Installation of the aluminum alloy base: The main keel base 7 is connected to the position of the steel base 8 to ensure that the connection is in place, and it is not temporarily fastened in place.

[0060] (5) On-site skeleton assembly: The main keel 2 and the secondary keel 3 are connected and fixed through the cross beam connecting piece 11, and assembled into an integral keel frame in blocks according to the design drawings. The main keel adjusting code piece 6 is also assembled to the integral keel frame in advance according to the established position.

[0061] (6) On-site assembly: Lift and install the assembled integral dragon skeleton according to the on-site numbers. After hoisting in place, adjust the main keel adjusting fittings 6 and the main keel base 7 in place on-site, and fasten and connect them with the second fasteners 16. After all connection points are connected and fixed in place to meet the design requirements, then fasten and lock all the fasteners. After the installation and fastening of the integral dragon skeleton are completed, install the curved glass 1 of the daylighting roof. The glass and the profiles are directly pressed, isolated and supported by the ethylene propylene diene monomer rubber strip one 12 and the ethylene propylene diene monomer rubber strip two 19. The glass pressing plates 5 are fixed and connected at a certain interval with the sixth fasteners 23 to press and fix the glass. Finally, fasten the decorative cover 4 on the glass pressing plate 5.

[0062] (7) Sealing and concealment: This system is applied to the special-shaped daylighting roof curtain wall, which has good drainage channels. Two rubber strips are used for sealing at the upper and lower edges of the glass in the exposed frame part, ensuring the basic airtightness and watertightness of the curtain wall system. Before the construction of the glass pressing plate 5, after the curved glass 1 of the daylighting roof is installed on the aluminum alloy main keel 2, sealant is applied at the connection gap position; for the hidden frame part, sealant is directly applied at the glass gap; it should be noted that at the intersection position of the glass seams in the exposed frame part and the glass seams in the hidden frame part, the continuity and integrity of the sealant should be ensured. The exposed frame decorative cover 4 should be arranged in the drainage direction to avoid water accumulation on the daylighting roof.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
