Preferably, the angle sign indicating number intracavity is provided with two pairs of protruding muscle, protruding muscle will two regions of lower floor in the three region that the angle sign indicating number chamber was cut apart are used for holding and installing the angle sign indicating number.
Preferably, the sealing edge is provided with a corner piece fixing groove, and the corner piece fixing groove is used for installing the corner piece.
Preferably, a first concave part is arranged on the long hole cavity, a second concave part is arranged on the corner connection cavity, and the first concave part and the second concave part are used for accommodating screws for connection.
Preferably, the frame section bar and the corner connector are made of aluminum alloy materials.
Preferably, the long hole cavity and the outer side of the corner brace cavity are flush, and the outer side of the short hole cavity is recessed inwards relative to the outer side of the corner brace cavity.
The utility model discloses for prior art gain following technological effect:
the utility model discloses a frame construction of loft formula stair, elegant appearance, the material is lighter, frame construction's frame section bar body simple structure, and the processing is nimble, and durable, and installation easy operation helps realizing mass production.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural view of a frame structure of the loft retractable staircase of the present invention;
wherein: 1-frame section bar, 2-long hole cavity, 3-corner code cavity, 4-short hole cavity, 5-convex rib, 6-first concave part, 7-second concave part, 8-sealing edge covering and 9-corner piece fixing groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The utility model aims at providing a frame construction of loft formula stair to solve the problem that prior art exists, make frame construction's simple to operate swift, and the connecting piece can hide the setting, make frame construction's appearance pleasing to the eye.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1: the embodiment provides a frame construction of loft formula stair that stretches out, including four frame section bars 1, has set gradually long vestibule 2, angle sign indicating number chamber 3 and short pore chamber 4 on the frame section bar 1, and 4 inboard in short pore chamber are connected with the sealed 8 of borduring, are provided with angle piece fixed slot 9 on the sealed 8 of borduring, and angle piece fixed slot 9 is used for the installation angle piece. The in-process of the installation of entrance to a cave is pressed close to the medial surface of frame section bar 1, and the angle sign indicating number piece is inserted in two angle sign indicating number piece fixed slots, and the installation is dismantled conveniently, still makes two frame section bar 1's surfacing, and is more pleasing to the eye.
The corner brace cavity 3 is communicated with the short hole cavity 4, the frame section bar 1 is fixed into a rectangular frame through corner braces and screws, and the corner brace cavity 3 is used for containing and installing the corner braces. Two pairs of convex ribs 5 are arranged in the corner brace cavity 3 in the embodiment, and the convex ribs 5 are used for accommodating and mounting corner braces in two lower layers of three regions divided by the corner brace cavity 3. The two frame profiles 1 are fixed together through the two corner connectors, so that the connection is firm and reliable, welding is omitted, the environment is protected, labor is saved, the processing time is shortened, and the production cost is reduced. After the frame profiles 1 are connected, a rectangular frame is formed and embedded in the hole, the sealing edge 8 can seal the periphery of the hole, and connecting pieces used in assembly and processing are hidden, so that the structural frame is good in integrity and attractive in appearance, and can also play the roles of dust prevention, wind prevention and rain prevention.
