The first embodiment is as follows: as shown in fig. 1 to 4, which are only one embodiment of the present invention, a ceiling access hole structure includes two L-shaped frames 1 and a cover plate 2 disposed between rectangles enclosed by the two L-shaped frames 1, where each L-shaped frame 1 includes a vertical plate 11, a first horizontal plate 12 disposed at an upper end of the vertical plate 11, a second horizontal plate 13 disposed at a lower end of the vertical plate 11, and a third horizontal plate 14 disposed between the first horizontal plate 12 and the second horizontal plate 13, one end of the first horizontal plate 12, which is far away from the vertical plate 11, is provided with a limiting plate 15, both the second horizontal plate 13 and the third horizontal plate 14 are disposed at one side of the vertical plate 11, which is far away from the limiting plate 15, at least a portion of the cover plate 2 is located between the second horizontal plate 13 and the third horizontal plate 14, the first horizontal plate 12 is connected to a keel 51 for mounting a ceiling plate 5, and the first horizontal plate 12, a portion of an end of the, Second diaphragm 13 and third diaphragm 14 all are provided with 45 oblique edges, two L type frame 1 connects through L type angle sign indicating number 4, be provided with connecting screw 41 on the L type angle sign indicating number 4.
In the invention, the ceiling plate 5 is arranged below the keel 51, the access hole is arranged at the ceiling plate 5, the two L-shaped frames 1 and the cover plate 2 arranged between the rectangles enclosed by the two L-shaped frames 1 are both arranged at the access hole, the ceiling plate 5 is arranged at the outer side of the L-shaped frame 1, the cover plate 2 is arranged at the inner side of the L-shaped frame 1, the first transverse plate 12 of the L-shaped frame 1 is connected with the keel 51, the mass of the two L-shaped frames 1 and the cover plate 2 is shared to the keel 51, and the ceiling plate 5 cannot be extruded.
First is L type frame 1's structure, L type frame 1 include riser 11, set up in first diaphragm 12 of riser 11 upper end, set up in second diaphragm 13 of riser 11 lower extreme and set up in third diaphragm 14 between first diaphragm 12 and the second diaphragm 13, second diaphragm 13 and third diaphragm 14 all set up in riser 11 is kept away from one side of limiting plate 15. In practice, the first horizontal plate 12 extends outward of the L-shaped frame 1, and the second horizontal plate 13 and the third horizontal plate 14 extend inward of the L-shaped frame 1.
Here, L type frame 1 is the integrated into one piece through assembled installation, and the efficiency of construction is high, more green.
Then two L-shaped frames 1 are connected, 45-degree inclined edges are arranged on a first transverse plate 12, a second transverse plate 13 and a third transverse plate 14 at the end parts of the L-shaped frames 1, and the side surfaces of the 45-degree inclined edges of the first transverse plate 12, the second transverse plate 13 and the third transverse plate 14 are stamping surfaces. Two L type frame 1 connects through L type angle sign indicating number 4, be provided with connecting screw 41 on the L type angle sign indicating number 4, actually, two L type frame 1 connects through two L type angle sign indicating numbers 4, here, second diaphragm 13 is kept away from the length of the one end of riser 11 is not more than first diaphragm 12 is kept away from the length of the one end of riser 11, that is to say L type frame 1 outside is wide, and the inboard is narrow, just can constitute a rectangle with two L type frames 1.
Then the position of the cover plate 2, the cover plate 2 is at least partially located between the second transverse plate 13 and the third transverse plate 14, the cover plate 2 has four sides, two sides are located between the second transverse plate 13 and the third transverse plate 14 of one L-shaped frame 1, and two sides are located between the second transverse plate 13 and the third transverse plate 14 of the other L-shaped frame 1, it should be noted that the two L-shaped frames 1 are connected and fixed through the two L-shaped corner connectors 4 after the cover plate 2 is clamped between the second transverse plate 13 and the third transverse plate 14 of the two L-shaped frames 1, the construction requirement is low, the quality problem is not easy to occur, the cover plate 2 is hidden between the second transverse plate 13 and the third transverse plate 14 and is not exposed, even if the cover plate 2 is opened and closed for many times, the decoration effect is more durable.
Last is fixed of whole access hole structure, first diaphragm 12 is connected with the fossil fragments 51 that are used for installing furred ceiling board 5, first diaphragm 12 is kept away from the one end of riser 11 is provided with limiting plate 15, and first diaphragm 12 is located fossil fragments 51 top, and limiting plate 15 is located fossil fragments 51 and keeps away from one side of riser 11, that is to say, first diaphragm 12 and limiting plate 15 catch on fossil fragments 51.
Of course, the first horizontal plate 12 on one side of each of the two L-shaped frames 1 is mounted on the keel 51, and the stability is good after mounting.
In a word, two L type frames 1 are fixed through L type angle sign indicating number 4, just constitute a rectangular structure, fill to the access hole department of furred ceiling board 5, and 2 tip cards of apron are to extending to L type frame 1 inboard and set up between second diaphragm 13 and the third diaphragm 14, and the first diaphragm 12 that extends the setting to L type frame 1 outside then catches on fossil fragments 51 above furred ceiling board 5 for undertake the weight of whole structure to fossil fragments 51 department.
The ceiling access hole structure is simple in structure, convenient to construct, high in construction efficiency, more environment-friendly, low in construction requirement, not prone to quality problems, good in stability after installation, not prone to damage due to repeated opening and closing, more durable in decoration effect and good in attractiveness, and is installed in an assembly mode.
In the second embodiment, as shown in fig. 1 to 4, the second embodiment is only one embodiment of the present invention, and on the basis of the first embodiment, in the ceiling service hole structure of the present invention, the width of the third horizontal plate 14 is not less than the width of the second horizontal plate 13, so as to prevent the cover plate 2 from loosening.
Also, the limiting plate 15 with distance between the riser 11 is not less than fossil fragments 51's width, and generally speaking, the distance between the limiting plate 15 on the relative both sides of rectangular structure that L type frame 1 constitutes just equals the distance between two fossil fragments 51 plus two fossil fragments 51's width for two limiting plates 15 just can block the one side that two fossil fragments 15 kept away from each other, and the rectangular structure that L type frame 1 constitutes like this is stable, is difficult for rocking the edge of collision furred ceiling board 5.
And, the connecting screw 41 is a countersunk head self-drilling screw, and of course, the number of the connecting screw 41 is at least one. The connection of the two L-shaped frames 1 is more stable.
Finally, the thickness of the cover plate 2 is not greater than the distance between the second horizontal plate 13 and the third horizontal plate 14. Generally, the thickness of the cover plate 2 is just equal to the distance between the second transverse plate 13 and the third transverse plate 14, so that the cover plate 2 is just clamped between the second transverse plate 13 and the third transverse plate 14 and is not easy to loosen.
In a third embodiment, as shown in fig. 5, the present invention further provides a method for installing a ceiling access opening structure in all the above embodiments, including the following steps:
