Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, specifically, it relates to a curtain wall keel structure and its installation method. Background Technology

[0002] Currently, curtain wall keel installation mostly involves welding or splicing horizontal and vertical keels. Existing keel installation methods have the following significant drawbacks:

[0003] (1) Due to inaccurate positioning and layout; workers' arbitrary construction and poor quality awareness, the position of the main keel is deviated and the geometric dimensions do not meet the design requirements. The verticality of the keel frame and the horizontality of the beam are significantly deviated. (2) Due to the failure to mark the grid on the main keel or the incorrect layout, the horizontal keel is not welded horizontally. (3) Due to inaccurate layout, the spacing and elevation of the secondary keel do not meet the requirements. (4) Due to inadequate handover, workers cut corners and used electric welding to blow holes in the horizontal keel without anti-corrosion treatment. (5) Due to poor welding skills, the welding length and weld corner size do not meet the requirements, the welding quality is poor, and the weld length is insufficient. (6) Due to poor quality awareness, workers cut corners and used incorrect or inaccurate materials, the weld is filled with steel bar ends or welding rods.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] Example 1

[0037] The following is in conjunction with the appendix Figure 1-7 This embodiment will be further described as follows:

[0038] This embodiment provides a curtain wall keel structure 10. Please refer to [link / reference]. Figure 1-7The curtain wall keel structure 10 includes a connector 100. The structure of the connector 100 is not specifically limited. In this embodiment, the connector 100 includes a vertical keel 200 connecting section for accommodating the vertical keel 200, two sets of horizontal keel 300 connecting assemblies, a drive assembly 130, and a push rod 140.

[0039] In this embodiment, two sets of horizontal keel 300 connecting components are symmetrically connected on opposite sides of the vertical keel 200 connecting segment with the axis of the vertical keel 200 connecting segment as the center line.

[0040] In this embodiment, the horizontal keel 300 connecting assembly includes a distance adjustment assembly (not shown in the figure) and a first clamping section 121 and a second clamping section 122 arranged symmetrically. A first receiving space 123 for accommodating the horizontal keel 300 is formed between the first clamping section 121 and the second clamping section 122. One end of the first clamping section 121 is fixedly connected to the vertical keel 200 connecting section, and the second clamping section 122 is movable along the length direction of the vertical keel 200 connecting section. Specifically, the vertical keel 200 section has recessed limiting grooves 111 on both sides along its width direction, and the limiting grooves 111 extend along the length direction of the vertical keel 200 section. One end of the second clamping section 122 is slidably connected to the limiting grooves 111 to further limit the sliding movement of the second clamping section 122. In this embodiment, the length direction of the first clamping segment 121 and the second clamping segment 122 is perpendicular to the length direction of the connecting segment of the vertical keel 200, so that the vertical keel 200 and the horizontal keel 300 are arranged vertically.

[0041] In this embodiment, the distance adjustment assembly includes a first hinge rod 124 and a second hinge rod 125 that are arranged crosswise and hinged together. One end of the first hinge rod 124 is hinged to a first clamping section 121, and the other end is hinged to a second clamping section 122 and can slide along the length of the second clamping section 122. One end of the second hinge rod 125 is hinged to the second clamping section 122, and the other end is hinged to the first clamping section 121 and can slide along the length of the first clamping section 121. In this embodiment, a push rod 140 is connected to the end of the second hinge rod 125.

[0042] At this time, simply pushing the push rod 140 will cause the second hinge rod 125 and the first hinge rod 124 to move in a hinged motion, thereby causing the second clamping part to move closer to or away from the first clamping part, thereby changing the size of the first accommodating space 123.

[0043] In this embodiment, the push rod 140 has a connecting hole 141, and the first clamping section 121 has a sliding groove 126. The sliding groove 126 extends along the length of the first clamping section 121, and the second hinge rod 125 can slide along the sliding groove 126. The connecting hole 141 communicates with the sliding groove 126. The push rod 140 can be fixed to the first clamping section 121 by bolts and screws, thereby fixing the first accommodating space 123 after adjusting it to a suitable size to prevent it from sliding again.

[0044] In this embodiment, the drive assembly 130 includes a first rack 131, a second rack 132, a first connecting rod 133, a second connecting rod 134, a first drive gear 135, a second drive gear 136, a first transmission gear 137, and a second transmission gear 138.

[0045] The first connecting rod 133 and the second connecting rod 134 are arranged parallel to each other on their axis, and both the first connecting rod 133 and the second connecting rod 134 are rotatably connected to the connecting section of the vertical keel 200. The axis of the first connecting rod 133 is perpendicular to the length direction of the connecting section of the vertical keel 200. The first driving gear 135 and the first transmission gear 137 are coaxially sleeved on the first connecting rod 133, and the second driving gear 136 and the second transmission gear 138 are coaxially sleeved on the second connecting rod 134. The first transmission gear 137 and the second transmission gear 138 mesh. One end of the first rack 131 meshes with the first driving gear 135, and the other end is connected to the second hinge rod 125. One end of the second rack 132 meshes with the second driving gear 136, and the other end is connected to the second hinge rod 125 of another set of horizontal keel 300 assemblies.

[0046] In this embodiment, when the push rod 140 is pushed, the push rod 140 causes one of the second hinge rods 125 to slide and simultaneously causes the first rack 131 to move along a direction parallel to the length of the first clamping section 121, thereby causing the first drive gear 135 to rotate. The first drive gear 135 causes the first connecting rod 133 to rotate, the first connecting rod 133 causes the first transmission gear 137 to rotate, the first transmission gear 137 causes the second transmission gear 138 to rotate, the second transmission gear 138 causes the second connecting rod 134 to rotate, the second connecting rod 134 causes the second drive gear 136 to rotate, and the second drive gear 136 causes the second rack 132 to move in a direction parallel to the first gear, thereby causing the other set of second hinge rods 125 to move in the opposite direction, thereby simultaneously causing the size of the first receiving space 123 of the other set of keel connecting components to change in the same way.

[0047] In this embodiment, the vertical keel 200 connecting section is detachably connected to the vertical keel 200, and the horizontal keel 300 is detachably connected to the first clamping section 121 and the second clamping section 122. Specifically, the vertical keel 200 can be connected to the vertical keel 200 connecting section by bolts and screws, and the horizontal keel 300 can be connected to the first clamping section 121 and the second clamping section 122 by bolts and screws.

[0048] This embodiment also provides an installation method for the above-mentioned curtain wall keel structure 10, including: connecting the vertical keel 200 to the vertical keel 200 connecting section; then, according to the width of the horizontal keel 300, pushing one of the second hinge rods 125 to the same distance between the first clamping section 121 and the second clamping section 122 in the same group of horizontal keel 300 components until the distance is consistent with the width of the horizontal keel 300; at this time, the other group of horizontal keel 300 components is adjusted simultaneously; then connecting the two horizontal keels 300 to the corresponding horizontal keel 300 components one by one.

[0049] In summary, this embodiment provides a curtain wall keel structure 10 and its installation method. The curtain wall keel structure 10 is ingeniously designed, significantly reducing installation difficulty, improving installation efficiency, connection strength, and connection stability. It facilitates the connection of vertical keels 200 and horizontal keels 300, and can self-adjust according to different sizes of horizontal keels 300. The adjustment operation is very convenient and easy, applicable to various sizes of horizontal keels 300, and has a wide range of applications. The installation method is convenient to operate, saving time and effort.
