Abstract

The frame of a pre-fabricated building, including metal posts, floor beams and auxiliary beams from cold-formed C-profiles, wood reinforcement elements and self-tapping screws, characterized in that the wood reinforcement elements are attached to the metal posts with self-tapping screws along the entire height in increments of no more than 200 mm , at the same time, the auxiliary floor beams are held by reinforcement elements made of wood, pass through through the cuts in them, and the floor beams rest on the upper flange of the auxiliary beam.

Description

The utility model relates to the field of construction of prefabricated buildings from steel cold-formed galvanized profiles.

Known designs of cold-formed galvanized profiles, the connection between the elements in which is carried out only on self-tapping screws. The nodes of such structures are unreliable, due to the low bearing capacity of self-tapping screws for shearing and pulling. At the same time, an increase in the number of self-tapping screws in the assembly does not always lead to an increase in the reliability of this assembly and the structure as a whole (Pat. 97145 Russian Federation, IPC E04B 1/24. Frame of a building from channels / Khisamov R.I .; applicant and patentee Khisamov R .I. - No. 201003058/03; claimed 29.01.2010; published on 08.27.2010, - 5 pp., Ill.) [1]. The disadvantage of such nodes is their unreliable work on dynamic load.

A known construction of prefabricated buildings with a metal frame, where the frame elements are made of square or round pipes and are interconnected by welding. As enclosing structures, three-layer panels are used located in the same plane with the frame (Pat. 2412308 Russian Federation, IPC E04B 2/00. The enclosing structure with a metal frame / A. Gryn; applicant and patent holder A. Gr. A. - No. 2009121490 / 03; claimed 08.06.2009; published on 02.20.2011, - 7 pp., Ill.) [2]. The disadvantages of this design is the significant complexity and duration of installation of the frame elements for welding, as well as the high material consumption.

The closest device in terms of features is the building frame structure made of wood-metal elements. (Hybrid Wood and Steel Details - Builder's Guide. - Implemented. 2003-01-07. - MD: NAHB Research Center Upper Marlboro, 2003. - 107 pp., Ill., Http://www.huduser.org/portal/ publications / Hybrid_Steelguide.pdf) [3].

The disadvantage of this design is that the rack frame is split in the area of the junction of the wall and floor. Thus, a two-story building consists of two separate buildings, floors, interconnected on pliable connections: self-tapping screws, bolts. Under the load acting in the horizontal direction, there is a likelihood of the building collapsing at the floor and wall interface. Such a frame design is irrational to use in two-story buildings. Wooden reinforcing elements in a frame of this kind are installed near window and door openings, but not in all racks of supporting external walls.

The technical result of the utility model is to increase the reliability of the node connecting the floors with walls and the structure of the building as a whole.

The technical result of the utility model is achieved by the fact that in the known frame of a pre-fabricated building, including metal racks, floor beams and auxiliary beams from cold-formed C-profiles, reinforcement elements made of wood and self-tapping screws, the feature is that reinforcement elements made of wood are attached to metal racks at the help of self-tapping screws along the entire height with a pitch of not more than 200 mm, while the auxiliary floor beams are held by reinforcing elements of wood, passing through the cuts in them, and the ball and ceilings are based on the top shelf of the auxiliary beams.

Enumeration of figures and graphic images. Figure 1 - diagram of a fragment of the frame of the building in the zone of the junction of the wall and floor, where the following notation is adopted: 1 - metal rack, 2 - reinforcement made of wood, 3 - auxiliary beam, 4 - floor beam, 6 - screws.

Figure 2 is a section of the wall of a two-story building, where the following notation is adopted: 1 - a metal stand, 2 - a reinforcing element made of wood, 3 - an auxiliary beam, 4 - a floor beam, 5 - foundation.

Figure 3 is a section of the wall of a three-story building with an attic, where the following notation is adopted: 1 - a metal stand, 2 - a reinforcing element made of wood, 3 - an auxiliary beam, 4 - a floor beam, 5 - foundation.

Figure 4 - cutting element reinforcement made of wood.

Reinforcing beams 3 of the floor at the column locations are reinforced with wood 2 from a beam with a cross section of 75 × 50, while the shelves of the auxiliary beam 3 are included in the cuts of the reinforcing element from wood 2. The load from the weight of the floor is transferred to the reinforcing element from wood 2, tightly connected to a metal rack 1 with screws 6 along the entire height of the wall. Through the reinforcement element made of wood 2, the force from the weight of the floor is transferred to the foundation 5. In the calculation of the building frame, the work of the reinforcement element from wood 2 on the load from the floor is taken into account, the work of the metal rack 1 - on the load from the weight of the roof and other loads. The advantage of this design is that the vertical load from the weight of the floor to the foundation 5 is transmitted through the reinforcing elements made of wood 2, and not through self-tapping screws 6 and the metal rack 1. At the same time, the width of the metal rack is reduced due to the reinforcement made of wood. Thus, the auxiliary beam 3 overlap is located inside the wall. The floor beams 4 are supported on the auxiliary beam 3 from above and fastened to it with self-tapping screws 6. The outer and inner wall claddings are installed along the edges of the metal-wooden column on the metal part and the wooden part, respectively.
