Description

The utility model relates to construction, namely to the connecting parts of spatial arch frame structures [IPC E04B1/32].

The prior art MOUNTING KIT FOR GEODESIC DOME [US 4844649 (A), publ. 07/04/1989], containing a central annular hub and a mounting bracket, which is designed for interconnection of each of the plurality of racks located along the circumference with the hub. The outer end of each mounting bracket includes two pieces that wrap around the rack and attach to the rack with two bolts. The inner end of each mounting bracket includes two axially spaced triangular-shaped protrusions, which are located at opposite ends of the hub and are attached to it with a bolt passing through both bracket protrusions.

The disadvantage of this analog is the complexity of the design of the mounting bracket, which adversely affects the reliability of the connections being implemented, as well as the limited number of geometries that can be implemented by the considered mounting kit.

Also known from the prior art is a BEARING STRUCTURE OR SIMILAR ELEMENTS AND STRUCTURAL ELEMENTS FOR THEM, IN PARTICULAR FOR DOME-SHAPED STRUCTURES [DE 3137202 (A1), publ. 05/19/1983], consisting of polygons made up of separate identical components, and the polygons are connected along their longitudinal edges and / or their corners, characterized in that the components are a system of rods or are frames, as well as connecting parts that are assembled in various combinations to form geometric structures based on the formation of triangles or the inclusion of triangular structures in such a way that the load-bearing parts, rods or frames along their side edges and/or at the corners are connected radially, forming knots.

The disadvantage of this analogue is the complexity of the design of fastening structural elements, which adversely affects the reliability of the implemented connections.

The closest in technical essence is a CONNECTOR FOR BEAMS [RU 2727996 (C1), publ. 07/28/2020], which is in the form of a solid flat part containing two bearing elements located at an angle to each other, with rectangular grooves made in them on one side of the flat part, bounded by bearing support areas located in the zone of greatest loads.

The main technical problem of the prototype is the symmetrical arrangement of the rectangular slots and bearing support sections, which is not optimal and leads to waste of material.

The purpose of the utility model is to eliminate the shortcomings of the prototype.

The technical result of the utility model is to reduce the consumption of materials while maintaining the strength characteristics of the connection.

The specified technical result is achieved due to the fact that the mounting pad for the nodes of the arched frame structures, made in the form of an elongated flat part, with an inclination of one part of the part relative to the other, the flat bases of the parts of the part are located in parallel planes, and the sections have different sizes, at the junction of the sections the part has a transverse groove, the part has mounting holes.

In particular, the slope can divide the part into two sections in a one-to-two ratio.

In particular, the slope of the portions of the part forms an arc.

In particular, mounting holes are made at the base of the groove in parts of the part.

Implementation of the utility model.

Mounting pads 9 are an important part of the nodes of the arched frame structures and are made in the form of oblong flat parts with kinks at one of the sides, along which transverse grooves 10 are made (Fig. 1, 2). In the mounting pads 9 (including the transverse grooves 10) mounting holes 3 are made, matching the mounting holes 3 made in the racks of the lower tier 1, racks of the upper tier 4 and spacers 11.

In the nodes of the arched frame structures (Fig. 3), the beams forming the frame are fastened, namely: the racks of the lower tier 1, the racks of the upper tier 4 and horizontally located spacers 11.

Racks of the lower tier 1 and racks of the upper tier 4 have trapezoidal grooves 2 and trapezoidal spikes 5, respectively. Additionally, mounting holes 3 are located on the racks of the lower tier 1 - one in the middle part and two near the base of the trapezoidal groove 2. Mounting holes 3 are located on the racks of the upper tier 4 - one in the middle part of the trapezoidal spike 5 (coaxial with the mating mounting hole 3 located in the middle parts of the trapezoidal groove 2 of the posts of the lower tier 1) and two directly above the trapezoidal spike 5. Trapezoidal grooves 2 and trapezoidal spikes 5 form the tongue-and-groove joints of the posts 6, which are fastened by mounting pads 9 and bolts 8 located on the left and right and located on the left and right. It is important to note that the angle of fracture mounting plate 9 corresponds to the angle of the tongue and groove connection of the racks 6.

In the transverse grooves 10 of the mounting pads 9, during the assembly of the structure, the ends of the horizontal struts 11 are located, on the outer end of which there are also end longitudinal spikes 7. On the outer ends of the racks of the lower tier 1 and racks of the upper tier 4, there are also end longitudinal spikes 7. Mounting holes 3 in transverse grooves 10 mounting pads 9 correspond to the mounting holes 3 in the ends of the spacers 11.

When erecting arched frame structures, mounting pads 9 are used in the following way. Two mounting pads 9 are attached to the ends of the strut 11 with a transverse groove 10 by means of bolts 8. Further, to the mounting pads 9 on both sides (on the flat side, where there are no transverse grooves 10), the racks of the lower tier 1 are attached with bolts 8.

Further, two new mounting plates 9 are attached to the uprights of the lower tier 1 on the free side of the mirror already fixed mounting plates 9 on the bolts 8. Thus, a single segment of the frame of the lower tier is assembled (see Fig. 4), and, repeating this operation, the lower tier of the required length and shape.

Further, in the trapezoidal grooves 2 of the racks of the lower tier 1, the racks of the upper tier 4 are installed with trapezoidal spikes 5, forming a tongue-and-groove connection of the racks 6 and starting to build the upper tier.

After the erection of the desired frame, the bolts 8 are pulled by the required moment.

An exemplary structure installed on site 12 is shown in figures 5-6.

The advantage of the mounting plates 9 of the presented design is the economy of the material from which they are made. Since if the transverse groove 10 would be located symmetrically, then within the framework of the presented design of the tongue and groove connection of the racks 6, the mounting plate 9 would be unreasonably long. The displacement of the transverse groove to one of the sides leads to a decrease in material consumption due to the reduction in the length of the mounting plate 9.

In 2020, the Applicant manufactured the parts of the arch frame structure assembly presented in this application, the operation of which confirmed the declared technical result.

The technical result of the utility model - reducing the consumption of materials while maintaining the strength characteristics of the connection, is achieved by manufacturing a mounting plate 9 with an inclination of one section of the part relative to another, moreover, the sections have different sizes, and a transverse groove 10 is made at the junction of the sections.
