Description
Technical Field
The utility model relates to the field of elevator shafts, in particular to a novel connecting node structure of an elevator shaft frame.
Background
Steel-structured elevator hoistway frames are typically comprised of steel columns and steel beams. The beam column installation connection mode in the traditional elevator shaft frame is shown in fig. 1, and the frame column and the steel beam are assembled in the elevator shaft directly by construction workers in a welding mode. In the figure, 1 is a frame column, 7 is a steel beam, and 6 is a weld joint.
Because cutting and welding work are required to be carried out in a narrow space in a villa room, a large risk of dynamic fire management and control exists, the welding difficulty is greatly increased compared with that of a professional production workshop, and the welding joint quality and the appearance quality are out of control due to the fact that the back wall body part is completely free of an operation space.
Therefore, it is particularly necessary to reduce the difficulty and risk of construction of the steel structure hoistway frame in a construction environment like a villa elevator, improve the construction efficiency, and improve the quality and appearance of the product.
Disclosure of Invention
The utility model aims to solve the problems in the prior art and provides a novel connecting node structure of an elevator shaft frame, which adopts bolt splicing to realize integrated assembly type spliced elevator steel structure shaft frames. The on-site assembly difficulty and construction time of the elevator shaft frame are effectively reduced, and the assembly quality and efficiency are improved.
The technical scheme adopted for solving the technical problems is as follows: novel connected node structure of elevator well frame, its characterized in that: the elevator shaft frame consists of a vertical frame column and a horizontal hollow truss, wherein two ends of the hollow truss are connected with two adjacent frame columns to jointly form a box type elevator shaft frame; the hollow truss consists of an upper chord member, a lower chord member and a web member, wherein a U-shaped connecting piece is fixedly arranged on the frame column, the end parts of the upper chord member and the lower chord member are arranged in the U-shaped connecting piece, and the overlapping parts of the end parts of the upper chord member and the lower chord member and the U-shaped connecting piece are respectively provided with a mounting hole which is mutually corresponding to each other and used for fastening and mounting bolts or screws.
As preferable: the U-shaped connecting piece notch is arranged along the extending direction of the frame column, and the mounting hole is formed from top to bottom along the side part of the U-shaped connecting piece.
As preferable: the mounting hole is a slotted hole, and the long diameter of the slotted hole is arranged along the extending direction of the frame column.
As preferable: the U-shaped connecting piece notch is arranged along the extending direction of the frame column, and the mounting hole is formed from top to bottom along the side part of the U-shaped connection.
The beneficial effects of the utility model are as follows:
1. the frame column and the hollow truss fixed with the U-shaped connecting piece can be directly conveyed to a construction site during construction, then a constructor only needs to splice the frame column and the hollow truss, the hollow truss is installed and fixed through bolts through bolt holes, the original direct welding mode is replaced by a bolt node structure mode, the field assembly difficulty is greatly reduced, the assembly efficiency is improved, and meanwhile, the assembled elevator shaft frame is more attractive.
Because traditional girder steel is based on national standard size, therefore the cross-section of girder steel is less can set up the mounting hole limited, carries out bolt or screw fixed connection steelframe whole atress and lateral rigidity in limited mounting hole and can reduce by a wide margin. Therefore, after the hollow truss is used, the upper chord member and the lower chord member are provided with mounting holes, so that the connection is relatively close to rigid connection, and the overall stress and lateral rigidity of the steel frame can be greatly improved.
2. The traditional steel structure needs to be welded with a plurality of sections of steel structures, the welding time of each section of steel structure is longer, professional welding personnel are needed, and the construction cost is increased to a certain extent. And the construction time is reduced after the bolts are adopted for connection, and the construction cost is also saved.

Detailed Description
The utility model is further described below with reference to the accompanying drawings:
embodiment one: as shown in fig. 2-6, the elevator shaft frame consists of a vertical frame column 1 and a horizontal hollow truss 2, wherein two ends of the hollow truss 2 are connected with two adjacent frame columns 1 to form a box type elevator shaft frame together;
the hollow truss 2 is composed of an upper chord member 21, a lower chord member 22 and a web member 23, wherein the upper chord member 21 and the lower chord member 22 are horizontally aligned up and down, and a U-shaped connecting piece 3 is fixedly arranged on the frame column 1, wherein the U-shaped connecting piece 3 is directly welded on the frame column 1 (the U-shaped connecting piece 3 can be directly welded on the frame column 1 in factory processing and then integrally transported to a construction site for elevator processing and installation).
Wherein the ends of the upper chord member 21 and the lower chord member 22 can be installed in the U-shaped connecting piece 3 (installed in the U-shaped groove of the U-shaped connecting piece 3), and the overlapping parts of the ends of the upper chord member 21 and the lower chord member 22 and the U-shaped connecting piece 3 are respectively provided with installation holes 4 which are mutually corresponding to each other and are used for fastening and installing bolts 5 or screws.
