Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and in particular relates to a metal sandwich panel unitized curtain wall system and its construction method. Background Technology

[0002] Metal sandwich panels are mostly used in industrial buildings. Industrial buildings often have a large enclosure area, and most metal sandwich panels are 1 meter wide. During on-site construction, each unit of metal sandwich panels is usually hoisted one by one using lifting equipment and installed on the wall purlins of the building. This consumes a lot of manpower and time for the installation of sandwich panels. Since industrial buildings usually have tight schedule requirements, each professional construction team needs a large working area, which leads to conflicts in the scheduling of various professional construction projects. To a certain extent, this increases the time for on-site manual labor and construction, and also increases the probability of construction safety accidents. Summary of the Invention

Specific Implementation

[0039] Please refer to Figure 1 This is a side view structural diagram of a metal sandwich panel unit component curtain wall system provided in an embodiment of the present invention. The metal sandwich panel unit component curtain wall system includes wall purlins 10, unit purlins 20, and metal sandwich panel units 30.

[0040] The wall purlins 10 are provided on the building wall and include, but are not limited to, the building's ring beams, peripheral floor beams, and support columns connected to the peripheral floor beams and located around the building.

[0041] The unit purlin 20 is installed outdoors of the building, and the unit purlin 20 is detachably connected to the wall purlin 10. Specifically, the unit purlin 20 is generally vertically installed and distributed outdoors of the building, and is detachably connected to the aforementioned wall purlin 10. The specific connection method includes, but is not limited to, self-tapping screw connection or bolt connection.

[0042] The metal sandwich panel unit 30 is disposed on the side of the unit purlin 20 away from the wall purlin 10, and multiple metal sandwich panel units 30 are sequentially and continuously extended and connected to the unit purlin 20 along the wall height direction of the building to form a large wall panel structure 310.

[0043] Specifically, the metal sandwich panel unit 30 is disposed on the side of the unit purlin 20 facing away from the wall purlin 10, that is, the metal sandwich panel unit 30 and the wall purlin 10 sandwich the unit purlin 20 therein, and multiple metal sandwich panel units 30 are sequentially and continuously unfolded and connected together on the unit purlin 20 along its length direction, thereby forming the large wall panel structure 310 assembled from multiple metal sandwich panel units 30.

[0044] During wall construction, the large wall panel structure 310 is directly hoisted to the building wall, and the unit purlin 20 is connected to the wall purlin 10 through detachable connectors. This allows for the installation of multiple metal sandwich panel units 30 at once, effectively reducing on-site manual labor and construction time, avoiding repeated installations, and reducing on-site safety risks.

[0045] Additionally, please combine Figure 2 When assembling multiple metal sandwich panel units 30 into the large wall panel structure, a unit assembly platform 40 is also required.

[0046] Specifically, the unit assembly platform 40 is used to assemble multiple metal sandwich panel units 30 into the large wall panel structure 310; the unit assembly platform 40 includes two longitudinal frames 410 and two transverse frames 420, and the two longitudinal frames 410 and the two transverse frames 420 are connected to form a frame shape.

[0047] Both of the longitudinal frames 410 are provided with longitudinal slide grooves 411 along their length direction. An adjustable positioning element 412 is provided in the longitudinal slide groove 411. The adjustable positioning elements 412 on the two longitudinal slide grooves 411 are arranged opposite to each other to position the metal sandwich panel unit 30.

[0048] Both of the horizontal frame bodies 420 are provided with horizontal sliding grooves 421 along their length direction. A limiting and fixing member 422 is provided in the horizontal sliding groove 421. The limiting and fixing member 422 is used to connect the unit body purlin 20.

[0049] Specifically, the two longitudinal frames 410 and the two transverse frames 420 are connected end to end to form a frame shape. The frame can be rectangular or square. The connection between the longitudinal frames 410 and the transverse frames 420 can be welding or screw connection or other detachable connection forms.

[0050] A longitudinal slide groove 411 is provided above the longitudinal frame 410 along its length direction. The longitudinal slide groove 411 is generally located at the center of the longitudinal frame 410. The adjustable positioning member 412 is provided on the longitudinal slide groove 411. There is no limit to the number of the adjustable positioning members 412, but the adjustable positioning members 412 on the two longitudinal slide grooves 411 are generally arranged opposite each other to clamp and position the metal sandwich panel unit 30 on the longitudinal frame 410.

[0051] A transverse groove 421 is provided above the transverse frame 420 along its length. The transverse groove 421 is generally located at the center of the transverse frame 420. The limiting fastener 422 is provided on the transverse groove 421. There is no limit to the number of the limiting fasteners 422, but the limiting fasteners 422 on the two transverse grooves 421 are generally arranged opposite each other. The two opposite limiting fasteners 422 are used to connect the unit purlins 20. Here, multiple metal sandwich panel units 30 are connected together by the unit purlins 20 to form the large wall panel structure 310.

[0052] In use, the unit purlin 20 is connected to the limiting and fixing member 422, and then multiple metal sandwich panel units 30 are arranged sequentially above the unit purlin 20 and positioned and fixed by the adjustable positioning member 412. Then, the metal sandwich panel units 30 are connected to the unit purlin 20 by detachable connectors such as self-tapping screws or bolts to assemble into the large wall panel structure 310 in the form of a larger unit. Then, during wall construction, the large wall panel structure 310 is directly hoisted to the wall of the building, thereby effectively improving the work efficiency of large-area wall construction in industrial buildings.

[0053] Furthermore, the adjustable positioning member 412 is detachably connected to the bottom of the longitudinal slide groove 411, and the adjustable positioning member 412 is able to slide along the longitudinal slide groove 411.

[0054] Specifically, multiple adjustable positioning elements 412 are provided along the length direction of the longitudinal frame 410. The number of adjustable positioning elements 412 is used to position and fix the metal sandwich panel units 30 according to the number of units. In order to improve the firmness of fixing the multiple metal sandwich panel units 30, generally each metal sandwich panel unit 30 corresponds to at least one adjustable positioning element 412. The adjustable positioning element 412 is connected to the bottom of the longitudinal slide groove 411 by a detachable connection such as screws, and can slide along the length direction of the longitudinal slide groove 411, so that the assembly platform can assemble large wall panel structures of different specifications and larger unit forms.

[0055] Furthermore, the adjustable positioning member 412 is L-shaped, with one end detachably connected to the bottom of the longitudinal slide groove 411, and the other end extending out of the longitudinal slide groove 411 and extending towards the center of the two longitudinal frames 410.

[0056] Specifically, one end of the L-shaped adjustable positioning member 412 is a connecting end, which is detachably connected to the bottom of the longitudinal slide groove 411; the other end is a positioning and fixing end, which extends out of the longitudinal slide groove 411 and extends a distance toward the center of the two longitudinal frames 410, and the extended tail end is used to abut against the purlin 20 of the unit body or directly against the side of the metal sandwich panel unit 30 to clamp and position the metal sandwich panel unit 30.

[0057] In addition, one end of the limiting and fixing member 422 is detachably connected to the bottom of the transverse slide groove 421, and the other end is a receiving groove 4221 for accommodating the connecting unit purlin 20.

[0058] Specifically, one end of the limiting and fixing member 422 is connected to the transverse frame 420. The connection method is to detachably connect it to the bottom of the transverse slide groove 421 by means of screws or other connecting parts. The other end of the limiting and fixing member 422 is provided with the receiving groove 4221, which is used to receive and position the unit purlin 20 so as to facilitate the connection between the unit purlin 20 and the metal sandwich panel unit 30.

[0059] Furthermore, the limiting and fixing member 422 can slide along the transverse groove 421.

[0060] Specifically, multiple unit purlins 20 are generally provided along the length of the metal sandwich panel unit 30. In order to facilitate the adjustment of the spacing between the unit purlins 20, the limiting fastener 422 is detachably connected and can slide along the length of the transverse groove 421 to facilitate the adjustment of the spacing between the two unit purlins 20.

[0061] Furthermore, a scale 423 is provided on one side of the two horizontal frames 420 that are opposite to each other, for determining the position of the unit purlin 20.

[0062] Specifically, the two horizontal frames 420 are provided with scales 423 on their opposite sides. The scales 423 are scales that indicate length. The length between the two limiting fasteners 422 can be quickly read through the scales 423, that is, the position of the unit purlin 20 can be quickly and accurately determined. This provides accurate dimensional data for the purlin setting of the large wall panel structure 310 and improves the assembly efficiency of the large wall panel structure 310.

[0063] Furthermore, the metal sandwich panel unit assembly curtain wall system also includes a retractable support keel 201, which is disposed on the side of the metal sandwich panel unit 30 facing the wall purlin 10 and is located between two adjacent unit purlins 20.

[0064] Furthermore, the two ends of the retractable support keel 201 are detachably connected to the unit purlin 20, and are removed from the large wall panel structure 310 when the large wall panel structure 310 is installed on the building wall.

[0065] Specifically, when multiple metal sandwich panel units 30 are assembled into the large wall panel structure 310, the unit purlins 20 are prone to bending and deformation along their length. In order to improve the overall strength of the large wall panel structure, a retractable support keel 201 is provided between two unit purlins 20 along the length of the unit purlins 20. The two ends of the retractable support keel 201 are connected to the unit purlins 20 on both sides by detachable connection methods such as screws or bolts, thereby strengthening the integrity of the large wall panel structure and improving the assembly quality of the large wall panel structure.

[0066] It should be noted here that after the large wall panel structure 310 is installed on the wall, since it is well fixed to the wall purlin 10, the retractable support keel 201 can be removed and reused to improve resource utilization.

[0067] Furthermore, the wall purlin 10 includes vertical purlins 110 arranged along the height direction of the wall of the building and horizontal purlins 120 perpendicular to the vertical purlins 110.

[0068] Specifically, the vertical purlins 110 and the horizontal purlins 120 are arranged in an alternating pattern to form a grid, which provides more installation positions for the unit purlins 20, thereby improving the firmness and stability of the connection between the large wall panel structure 310 and the wall purlins 10.

[0069] In addition, the unit purlin 20 is connected to the vertical purlin 110 and / or the horizontal purlin 120 via detachable connectors. Here, the unit purlin 20 may be connected only to the vertical purlin 110, or it may also be connected to the horizontal purlin 120, or both. The specific connection method includes, but is not limited to, detachable connections using screws or self-tapping screws. The detachable connection method facilitates replacement, maintenance, and disassembly for reuse.

[0070] Furthermore, the unit purlin 20 is capable of reciprocating in a direction perpendicular to the wall of the building, and in a direction parallel to the wall of the building.

[0071] Specifically, the unit purlin 20 is connected to the wall purlin 10 via a connector, and its installation position can be adjusted via the connector. Specifically, it can reciprocate in a direction perpendicular to the wall of the building to adjust the distance between the large wall panel structure 310 and the wall purlin 10; and it can reciprocate in a direction parallel to the wall of the building to adjust the large wall panel structure 310 relative to the wall purlin 10 in the vertical and horizontal direction of the wall.

[0072] Furthermore, the metal sandwich panel unit 30 is connected to the unit purlin 20 by bolts or self-tapping screws, and the unit purlin 20 and the length direction of the metal sandwich panel unit 30 are perpendicular to each other.

[0073] Specifically, the metal sandwich panel unit 30 is generally rectangular, and the length direction of the unit purlin 20 is perpendicular to the length direction of the metal sandwich panel unit 30. They are detachably connected by bolts or self-tapping screws to facilitate replacement, maintenance and disassembly for reuse.

[0074] Furthermore, please refer to Figure 3 The present invention provides a method flowchart for constructing a metal sandwich panel unitized curtain wall system, comprising:

[0075] Step S100: Multiple metal sandwich panel units are sequentially unfolded and connected to the unit purlins to form a large wall panel structure.

[0076] Step S200: Use a crane to lift the large wall panel structure to the exterior wall of the building;

[0077] Step S300: Connect the side of the unit purlin facing away from the metal sandwich panel unit to the wall purlin on the exterior of the building.

[0078] Specifically, during wall construction, firstly, multiple relatively small metal sandwich panel units are sequentially unfolded and connected to unit purlins on the ground using detachable connection methods such as screws or self-tapping screws to form a large wall panel structure. Then, the assembled large wall panel structure is transported to the exterior wall of the building using a crane. Finally, the unit purlins are connected to the wall purlins of the building using detachable connectors. This allows for the installation of multiple metal sandwich panel units at once, effectively reducing on-site manual labor and construction time, avoiding repeated installations, and lowering the safety risks of on-site operations.

[0079] Further, please refer to Figure 4 This is another flowchart of a construction method for a metal sandwich panel unitized curtain wall system provided by an embodiment of the present invention. The unit purlins and the wall purlins are connected by detachable connectors. The construction method further includes:

[0080] Step S400: Adjust the spacing between the metal sandwich panel unit and the wall purlin using the detachable connector.

[0081] Furthermore, the construction method also includes:

[0082] In step S500, the purlin of the unit body is reciprocated and adjusted in a direction parallel to the wall surface of the building by means of the detachable connector.

[0083] Specifically, the detachable connector is located between the unit purlin and the wall purlin. The detachable connector allows for adjustment of the spacing between the metal sandwich panel unit and the wall purlin, i.e., adjustment of the spacing between the large wall panel structure and the wall purlin; and allows for reciprocating adjustment of the unit purlin in a direction parallel to the wall surface of the building, i.e., adjustment of the large wall panel structure relative to the wall purlin in the vertical and horizontal direction of the wall surface. This enables multi-angle adjustment of the installation position of the large wall panel structure through the detachable connector.

[0084] Furthermore, please combine Figure 5This is another flowchart of a construction method for a metal sandwich panel unitized curtain wall system provided by an embodiment of the present invention. Step S100, which involves sequentially unfolding multiple metal sandwich panel units and connecting them to the unit purlins to form a large wall panel structure, specifically includes:

[0085] Step S110: Connect the multiple unit purlins parallel to each other on the metal sandwich panel unit assembly platform;

[0086] Step S140: Arrange the plurality of metal sandwich panel units sequentially along the length of the unit purlin and connect them above the unit purlin.

[0087] In addition, in other preferred embodiments of the present invention, after step S110 connects the plurality of unit purlins parallel to each other on the metal sandwich panel unit assembly platform, the method further includes:

[0088] Step S120: Use the ruler on the metal sandwich panel unit assembly platform to position the unit purlins and adjust the spacing between the two unit purlins.

[0089] Furthermore, after connecting the plurality of unit purlins parallel to each other on the metal sandwich panel unit assembly platform in step S110, the method further includes:

[0090] Step S130: Arrange retractable support keels at intervals between two adjacent unit purlins.

[0091] Specifically, when assembling the large wall panel structure using the metal sandwich panel unit assembly platform, firstly, multiple unit purlins are connected parallel to each other on the metal sandwich panel unit assembly platform according to the planned dimensions; secondly, to improve the accuracy of the unit purlin installation and enhance the assembly quality of the large wall panel structure, the unit purlins are positioned using a scale on the metal sandwich panel unit assembly platform, and the spacing between two unit purlins is adjusted according to the preset dimensions; then, to improve the integrity and connection strength of the large wall panel structure and enhance the assembly quality, retractable support keels are arranged at intervals between two adjacent unit purlins. These retractable support keels are installed along the length of the unit purlins between two unit purlins, and both ends of the retractable support keels are connected to the unit purlins on both sides via detachable connections such as screws or bolts.

[0092] In other preferred embodiments of the present invention, after the side of the unit purlin facing away from the metal sandwich panel unit is connected to the exterior wall purlin of the building, the construction method further includes:

[0093] Step S600: Remove the retractable support keel between the unit purlins.

[0094] Specifically, after the large wall panel structure is installed on the wall purlin, since the large wall panel structure and the wall purlin are well fixed, the retractable support keel can be removed and reused to improve resource utilization.

[0095] Finally, it should be noted that the construction method of the metal sandwich panel unit component curtain wall system mentioned in the above embodiments corresponds to the metal sandwich panel unit component curtain wall system.
