Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a connecting device and a connecting method of a connecting claw of a glass curtain wall. Background Art

[0002] When installing the glass curtain wall outside the main steel structure, the docking claws of the point-type curtain wall are usually connected to the main steel structure. If the carbon steel base of the docking claws of the point-type curtain wall is to be welded to the main steel structure, the surface of the main steel structure needs to be relatively flat. Therefore, when constructing some steel structures with uneven surfaces, especially when the steel structure is a steel pipe skeleton connected by pipe fittings or rods and the outer facade of the steel skeleton is uneven, the carbon steel base of the docking claws of the point-type curtain wall cannot be firmly installed on the steel structure (steel pipe skeleton) with an uneven outer facade, which causes quality problems and safety hazards. Summary of the invention

[0003] In order to overcome the defects of the prior art, a connecting device and a connecting method of a glass curtain wall connecting claw are provided to solve the problem that the connecting claw of the point curtain wall is not easy to be firmly installed on the steel structure (steel pipe frame) when the steel structure with an uneven facade is constructed.

[0004] In order to achieve the above object, a connecting device of a docking claw of a glass curtain wall is provided, wherein a special-shaped frame is installed on the facade of a main structure, the special-shaped frame comprises a plurality of cross bars and a plurality of diagonal web bars, and a plurality of the diagonal web bars are intersected and connected to the upper side and the lower side of the cross bar, and the connecting device comprises:

[0005] A support assembly, comprising a pre-installed component and a post-installed component, wherein the pre-installed component has a first side and a second side opposite to each other, the first side of the pre-installed component is formed with a mounting groove for embedding the cross bar and the plurality of diagonal web bars at the intersection of the special-shaped frame, and the post-installed component is connected to the second side of the pre-installed component; and

[0006] A base plate for installing the docking claws is connected to a side of the post-installation component away from the pre-installation component.

[0007] Furthermore, the pre-assembled parts include:

[0008] a node reinforcement plate having a first side portion and a second side portion opposite to each other, the mounting groove being formed on the first side portion of the node reinforcement plate, and the second side portion of the node reinforcement plate being connected to the pre-assembled component; and

[0009] The reinforcing rib plate is used for supporting between the cross bar and the node reinforcement plate, and is connected to the side surface of the node reinforcement plate and the preassembled part.

[0010] Furthermore, two opposite side surfaces of the node reinforcement plate are respectively connected with the reinforcement ribs.

[0011] Furthermore, the reinforcing rib is perpendicular to the node reinforcement plate.

[0012] Furthermore, the aftermarket parts include:

[0013] a first flange plate connected to a second side portion of the node reinforcement plate away from the mounting groove, the first flange plate being arranged along a plate surface direction of the node reinforcement plate, and the cap plate being connected to a side of the first flange plate away from the node reinforcement plate; and

[0014] The second flange plate is connected between the base plate and the first flange plate, and the second flange plate is arranged along the plate surface direction of the reinforcing rib plate.

[0015] Furthermore, the connection device also includes a support plate, a first end of the support plate is overlapped with the node reinforcement plate and the first flange plate respectively, and a second end of the support plate is overlapped with the reinforcing rib plate and the second flange plate respectively.

[0016] The present invention provides a method for connecting a connecting claw of a glass curtain wall. A special-shaped frame is installed on the facade of a main structure. The special-shaped frame includes a plurality of cross bars and a plurality of diagonal web bars. The plurality of diagonal web bars are intersected and connected to the upper side and the lower side of the cross bar. The connection method includes the following steps:

[0017] The installation groove of the pre-assembled part of the support assembly is embedded in the cross bar and the plurality of diagonal web bars at the intersection of the special-shaped frame to reinforce the intersection of the special-shaped frame;

[0018] The thickness of the post-installed part is calculated based on the designed distance from the connecting claw to the intersection of the special-shaped frame, the thickness of the pre-installed part and the thickness of the base plate;

In addition, by controlling the thickness of the post-installed parts, the distance from the connecting claw to the special-shaped frame can be accurately controlled, thereby improving the installation accuracy of the connecting claw. The connection between the post-installed parts and the pre-installed parts is far away from the intersection connection, so the construction is convenient and fast, and the construction efficiency is greatly improved. The base plate provides a reliable installation plane for the carbon steel base of the connecting claw, thereby improving the installation quality of the connecting claw and avoiding safety hazards caused by loose installation of the connecting claw. In addition, the docking claws, base plates and post-installed parts can be pre-installed indoors and then installed outdoors on the pre-installed parts on the special-shaped frame, reducing the construction time of outdoor high-altitude operations and improving the construction safety of the glass curtain wall with special-shaped frames.

[0027] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0029] Reference Figures 1 to 4 As shown, in this embodiment, the special-shaped frame 1 is arc-shaped. Specifically, the special-shaped frame is installed on the facade of the main structure. The special-shaped frame 1 includes multiple cross bars 11 and multiple diagonal web bars 12. The cross bars are connected to the main structure through brackets. Multiple cross bars are arranged at intervals from top to bottom along the arc-shaped facade. Multiple diagonal web bars are connected between two adjacent cross bars. Multiple diagonal web bars 12 are intersectingly connected to the upper and lower sides of the cross bar 11. In this embodiment, there are two diagonal web bars on the upper side of the cross bar, and two diagonal web bars on the lower side of the cross bar. Four diagonal web bars are intersectingly connected to the cross bar, so that the intersection of the special-shaped frame is in the shape of a crossbar, as shown in FIG. Figure 2 As shown. The diagonal brace is connected to the cross bar. In this embodiment, Figure 1 As shown, the two oblique webs on the upper and lower sides of the cross bar are arranged at an angle, resulting in the outer facade of the overall special-shaped frame being uneven, but in an arc shape or other shapes.

[0030] Reference Figures 1 to 4 As shown, the present invention provides a connecting device for a docking claw of a glass curtain wall, comprising: a supporting assembly and a base plate 3. Specifically, the supporting assembly comprises a pre-installed component 21 and a post-installed component 22. The pre-installed component 21 has a first side and a second side opposite to each other. The first side of the pre-installed component 21 is formed with an installation groove for embedding a cross bar 11 at the intersection of the special-shaped frame 1 and a plurality of diagonal web bars 12. The post-installed component 22 is connected to the second side of the pre-installed component 21. The base plate 3 is used to install the carbon steel base 51 of the docking claw 5. The base plate 3 is connected to the side of the post-installed component 22 away from the pre-installed component 21.

[0031] The connecting device of the connecting claw of the glass curtain wall of the present invention is pre-installed at the intersection connection of the special-shaped frame through a pre-installed part. On the one hand, the pre-installed part has the function of reinforcing the intersection connection. On the other hand, the pre-installed part is pre-installed at the intersection connection of the special-shaped frame, so that when installing the connecting claw, it is avoided that the connecting claw is installed at the intersection of the rods of the special-shaped frame, which is inconvenient to install, thereby improving the installation construction efficiency of the connecting claw and reducing the installation difficulty of the connecting claw. In addition, by controlling the thickness of the post-installed part, the distance from the connecting claw to the special-shaped frame can be accurately controlled, thereby improving the installation accuracy of the connecting claw. The connection between the post-installed part and the pre-installed part is far away from the intersection connection, so the construction is convenient and fast, and the construction efficiency is greatly improved. The base plate provides a reliable installation plane for the carbon steel base of the connecting claw, thereby improving the installation quality of the connecting claw and avoiding safety hazards caused by loose installation of the connecting claw. In addition, the docking claws, base plates and post-installed parts can be pre-installed indoors and then installed outdoors on the pre-installed parts on the special-shaped frame, reducing the construction time of outdoor high-altitude operations and improving the construction safety of the glass curtain wall with special-shaped frames.

[0032] In this embodiment, the pre-installed component 21 includes: a node reinforcement plate 211 and a reinforcement rib plate 212. The function of the pre-installed component is, on the one hand, to reinforce the intersection of the special-shaped frame, improve the structural stability of the special-shaped frame, and thus improve the stability of the installation of the glass curtain wall. On the other hand, when making the special-shaped frame, the pre-installed component can be installed at the intersection of the rods of the special-shaped frame, avoiding the construction and installation at the intersection of the rods of the special-shaped frame in the outdoor high-altitude environment later, reducing the difficulty of installing the docking claw. In addition, the connection with the docking claw is extended or transferred to an open space through the pre-installed component, so that when the post-installed component is installed later, the subsequent installation process of the docking claw can be completed more quickly and conveniently.

[0033] Specifically, the node reinforcement plate 211 has a first side portion and a second side portion opposite to each other. The first side portion of the node reinforcement plate 211 is formed with the installation groove. The node reinforcement plate 211 is welded and connected to the crossbar and diagonal web of the special-shaped frame to reinforce the intersection of the rods of the special-shaped frame. The second side portion of the node reinforcement plate 211 is connected to the pre-assembled part. After installation, the reinforcing rib 212 is supported between the crossbar 11 and the node reinforcement plate 211. The reinforcing rib 212 is connected to the side of the node reinforcement plate 211 and the pre-assembled part.

[0034] In this embodiment, the node reinforcement plate 211 is arranged along the radial direction of the crossbar, and the reinforcement rib plate 212 is arranged along the axial direction of the crossbar. The reinforcement rib plate 212 is perpendicular to the node reinforcement plate 211.

[0035] As a preferred embodiment, two opposite sides of the node reinforcement plate 211 are respectively connected with reinforcement ribs 212. In this embodiment, there are two reinforcement ribs 212, which are respectively connected between one side of the node reinforcement plate 211 and the outer wall of the crossbar, and between the other side of the node reinforcement plate 211 and the outer wall of the crossbar.

[0036] The node reinforcement plate 211 is arranged along the symmetry center line of the intersection of the special-shaped frame. Specifically, the two diagonal webs on the upper side of the cross bar are symmetrically arranged on both sides of the node reinforcement plate 211, and the two diagonal webs on the lower side of the cross bar are symmetrically arranged on both sides of the node reinforcement plate 211.

[0037] The diagonal web bars on the upper side of the cross bar and the diagonal web bars on the lower side of the cross bar are symmetrically arranged on both sides of the reinforcing rib plate 212 .

[0038] In order to facilitate the connection to the pre-assembled part, as a preferred embodiment, the post-assembled part 22 includes: a first flange plate 221 and a second flange plate 222. Specifically, the first flange plate 221 is connected to the second side of the node reinforcement plate 211 away from the installation groove. The first flange plate 221 is arranged along the plate surface direction of the node reinforcement plate 211. The base plate 3 is connected to the side of the first flange plate 221 away from the node reinforcement plate 211. The second flange plate 222 is connected between the base plate 3 and the first flange plate 221. The second flange plate 222 is arranged along the plate surface direction of the reinforcing rib plate 212.

[0039] In this embodiment, the length of the first flange plate 221 of the after-installed component is smaller than the length of the node reinforcement plate 211 of the pre-installed component; the length of the second flange plate 222 of the after-installed component is smaller than the length of the reinforcing rib plate 212 of the pre-installed component.

[0040] The thickness of the first flange plate 221 of the after-installed component matches the thickness of the node reinforcement plate 211 of the pre-installed component; the thickness of the second flange plate 222 of the after-installed component matches the thickness of the reinforcing rib plate 212 of the pre-installed component.

[0041] In this embodiment, the node reinforcement plate 211, the reinforcing rib plate 212, the first flange plate 221, the second flange plate 222, and the cap plate 3 are all steel plates. When the first flange plate 221 and the second flange plate 222 are connected to the node reinforcement plate 211 and the reinforcing rib plate 212, the first flange plate 221 and the second flange plate 222 are subjected to on-site beveling processing and then welded to the node reinforcement plate 211 and the reinforcing rib plate 212.

[0042] As a preferred embodiment, the connection device further includes a support plate 4, in order to reinforce the pre-installed parts and the post-installed parts, and to facilitate the subsequent spraying process, cover the construction welds, and make the appearance of the steel structure more beautiful. The first end of the support plate 4 is overlapped with the node reinforcement plate 211 and the first flange plate 221, and the second end of the support plate 4 is overlapped with the reinforcing rib plate 212 and the second flange plate 222.

[0043] In this embodiment, the first side of the docking claw 5 has a carbon steel base 51, and the second side of the docking claw 5 is installed with curtain wall glass 6. Therefore, the sum of the length of the support plate and the thickness of the base plate is equal to the design distance from the carbon steel base of the docking claw to the special-shaped frame. In addition, the sum of the thickness of the base plate, the thickness of the pre-installed parts and the thickness of the post-installed parts is also equal to the design distance from the carbon steel base of the docking claw to the special-shaped frame. The post-installed parts are made now, and the thickness of the post-installed parts can be calculated based on the thickness of the base plate, the thickness of the post-installed parts and the design distance from the carbon steel base of the docking claw to the special-shaped frame.

[0044] The present invention provides a method for connecting a connecting claw of a glass curtain wall, wherein a special-shaped frame 1 is installed on the facade of a main structure, the special-shaped frame 1 comprises a plurality of cross bars 11 and a plurality of diagonal web bars 12, and the plurality of diagonal web bars 12 are intersected and connected to the upper side and the lower side of the cross bar 11, and the connection method comprises the following steps:

[0045] S1: The installation groove of the preassembled part 21 of the support assembly is embedded in the cross bar 11 and multiple diagonal webs 12 at the intersection of the special-shaped frame 1 to reinforce the intersection of the special-shaped frame 1.

[0046] When preparing the special-shaped skeleton, the installation grooves of the pre-assembled parts are embedded in the cross bars 11 and multiple diagonal webs 12 at the intersection of the special-shaped skeleton 1. On the one hand, the intersection of the special-shaped skeleton 1 is reinforced, and on the other hand, the installation point of the docking claw is transferred to the outside of the intersection of the special-shaped skeleton 1 (i.e., the area where the rods intersect densely), so that the subsequent installation of the docking claws is quick and convenient.

[0047] S2: The thickness of the post-installation part 22 is calculated based on the designed distance between the connection claw 5 and the intersection of the special-shaped frame 1, the thickness of the pre-installation part 21 and the thickness of the base plate 3.

[0048] Measure the thickness of the pre-installed parts and the thickness of the base plate, and obtain the thickness of the post-installed parts by subtracting the thickness of the pre-installed parts and the thickness of the base plate from the designed distance.

[0049] S3: manufacturing the after-installation component 22 according to the thickness of the after-installation component 22 .

[0050] The after-installation parts are prepared on site according to the calculated thickness dimensions of the after-installation parts.
