Description

Technical Field

[0001] This utility model belongs to the field of color steel plate technology, specifically, it relates to a double-layer heat-insulating color steel plate. Background Technology

[0002] Double-layer color steel sheet, also known as pre-coated steel sheet, is an advanced building material consisting of two layers of metal panels and a middle core layer. This type of sheet not only has excellent mechanical properties but also outstanding fire resistance, heat insulation, sound insulation, and thermal insulation effects. Due to its unique structure and performance advantages, double-layer color steel sheet has become the preferred material for the walls and roofs of prefabricated houses and mobile homes, as well as building structures requiring special protection and thermal insulation.

[0003] Although double-layer color steel plates have been widely used in the market, during the installation process, after the color steel plates are fixed to the supporting structure, the adjacent two sets of color steel plates are fixed with structural adhesive. This fixing method results in insufficient connection strength at the splicing of the color steel plates, which in turn affects the safety of the entire building. Utility Model Content

[0010] Furthermore, the locking mechanism includes a fixing pin passing through the receiving groove, a threaded rod that can rotate on the fixing pin, a washer sleeved on the threaded rod, and a locking nut screwed onto the threaded portion of the threaded rod.

[0011] Furthermore, a clearance groove is provided on the upper side wall of the locking groove and the lower side wall of the receiving groove respectively; the width of the clearance groove is greater than the outer diameter of the threaded rod, but smaller than the outer diameter of the gasket.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] See Figure 1and 4 As shown in Figure 5, a double-layer thermally insulated color steel plate includes an upper substrate 1 and a lower substrate 2. A thermal insulation layer 3 and a heat insulation layer 4 are disposed between the upper substrate 1 and the lower substrate 2. A surrounding plate 5 is arranged around the thermal insulation layer 3 and the heat insulation layer 4 located between the upper substrate 1 and the lower substrate 2. A connecting plate 6 is disposed on one side wall of the surrounding plate 5. The connecting plate 6 is detachably connected to the surrounding plate 5 via a connector 7. A locking groove 61 is formed at the upper end of the connecting plate 6, and a receiving groove 62 is formed at the lower end of the connecting plate 6. A locking mechanism 63 is disposed in the receiving groove 62. Through the cooperation of the locking mechanism 63 and the locking groove 61, two adjacent sets of connecting plates 6 are locked together. Figure 8 As shown.

[0031] Further, see Figure 4 and Figure 6 As shown, in this embodiment, the connecting surfaces of the enclosure 5 and the connecting plate 6, as well as the opposing surfaces of their connecting surfaces, are respectively provided with connecting grooves 561 of the same shape and size. The connecting grooves 561 are either dovetail grooves or T-grooves. Of course, the above-mentioned shapes of the connecting grooves 561 are only two implementation methods and are not intended to limit the scope of this application. During connection, when the enclosure 5 and the connecting plate 6 are attached, the connecting grooves 561 on the attachment surfaces of the enclosure 5 and the connecting plate 6 correspond one-to-one and are arranged opposite each other. By inserting the connecting piece 7 into the corresponding connecting groove 561, the connecting plate 6 is connected to the enclosure 5. It should be noted that the connecting piece 7 can be inserted as a whole or multiple pieces can be inserted at intervals. The position of the connecting piece 7 is not limited, as long as it can ensure that the enclosure 5 and the connecting plate 6 are connected together.

[0032] Further, see Figure 7 As shown, in this embodiment, the connecting surfaces of the enclosure plate 5 and the connecting plate 6, as well as the opposing surfaces of the two connecting surfaces, are respectively provided with positioning holes 562 of the same shape and size. During connection, when the enclosure plate 5 and the connecting plate 6 are attached, the positioning holes 562 on the attachment surfaces of the enclosure plate 5 and the connecting plate 6 correspond one-to-one and are set opposite to each other. By inserting positioning pins 8 into the corresponding positioning holes 562, the position of the connecting plate 6 connected to the enclosure plate 5 is positioned, thereby improving the installation accuracy and effectively preventing the enclosure plate 5 and the connecting plate 6 from moving along the direction of the connecting groove 561.

[0033] Further, see Figure 2As shown, in this embodiment, the locking mechanism 63 includes a fixing pin 631 passing through the receiving groove 62, a threaded rod 632 rotatable thereon provided on the fixing pin 631, a washer 633 sleeved on the threaded rod 632, and a locking nut 634 screwed onto the threaded portion of the threaded rod 632; when locked, see Figure 8 As shown, by rotating the threaded rod 632 to the side of the locking groove 61 in the adjacent connecting plate 6, and then rotating the locking nut 634, the washer 633 abuts against the upper side wall of the locking groove 61 in the adjacent connecting plate 6, thereby locking the two adjacent sets of connecting plates 6 together; in this embodiment, see Figure 2-3 and Figure 8 As shown, a clearance groove 64 is respectively provided on the upper side wall of the locking groove 61 and the lower side wall of the receiving groove 62; the groove width of the clearance groove 64 is greater than the outer diameter of the threaded rod 632, but smaller than the outer diameter of the washer 633; ​​by providing the clearance groove 64, when the two adjacent sets of connecting plates 6 are locked together, the threaded rod 632 sinks into the connecting plate 6.

[0034] In this embodiment, see Figure 9 As shown, the gasket 633 is provided with two sets of limiting blocks 6331, but it is not limited to two sets; other numbers of sets can also be provided, such as one set, three sets, etc.; see also Figure 3 As shown, the upper side wall of the locking groove 61 is provided with a first limiting hole 611 that is adapted to the limiting block 6331; when the two adjacent sets of connecting plates 6 are locked, the cooperation between the limiting block 6331 and the first limiting hole 611 can effectively prevent the threaded rod 632 from moving and affecting the connection strength between the two adjacent sets of connecting plates 6, thereby improving the stability of the connection.

[0035] Further, see Figure 2 and Figure 8 As shown, in this embodiment, a fixing plate 65 is provided in the receiving groove 62, and a fixing groove 651 is formed on the fixing plate 65. The groove width of the fixing groove 651 is greater than the outer diameter of the threaded rod 632, but smaller than the outer diameter of the gasket 633. A second limiting hole 652 adapted to the limiting block 6331 is formed on the fixing plate 65. When the locking mechanism 63 is retracted into the receiving groove 62, see [details omitted]. Figure 2As shown, after the threaded rod 632 is housed in the fixing groove 651, the locking nut 634 is rotated so that the washer 633 abuts against the side wall of the fixing plate 65. At this time, the limiting block 6331 is inserted into the second limiting hole 652. Through the cooperation of the limiting block 6331 and the second limiting hole 652, damage is avoided caused by the threaded rod 632 rotating out of the receiving groove 62 due to vibration or other reasons during transportation or transfer.

[0036] Finally, it should be noted that when splicing the color steel plates of this application, the splicing method is as follows: Figure 10 As shown.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
