To solve the problem and achieve the technical result, a group of utility models is proposed, at least one of which is intended for use in another.

In one aspect of the utility model, a glued beam is proposed, which is a beam formed into a package that is glued and machined along a contour, characterized in that a plastic pipe is located inside the beam (polyvinyl chloride PVC, or polypropylene, or polyethylene, or made of composite materials), installed into a recess located inside the beam for its entire length, or to a part thereof.

A plastic pipe can be glued into the glued beam not for the entire length of the beam, but only for its part. The pipe can be glued both along and across the glued beam, and is also located at an angle.

The essence of the nodal connection of at least two glued beams, each of which one of its ends is adjacent to the connecting element, or to a structure consisting of several connecting elements, at least one of which is fixed in a plastic pipe located inside, at least at least one of the glued beams for its entire length or for its part, is illustrated by the figures:

In FIG. 7 is a cross-sectional view of the nodal connection of glued beams with connecting means in the form of a metal anchor having an internal thread.

The nodal connection of glued beams consists of a connecting corner element 73 made of metal and connected by a bolt 74 - connecting fastening means with an anchor 75 located inside a plastic, for example, polyvinyl chloride, polypropylene, polyethylene pipe 71, and fixed with connecting fastening means - pins 76 with glued beam 72.

In FIG. 8 shows an anchor. A thread is made inside one part of the anchor 85, and holes are made on the other part of the anchor into which pins 86 are mounted.

The design is collected as follows:

First, in the middle of the glued beam 72 (Fig. 7), a plastic pipe 71 is glued along its entire length or its part (a polyvinyl chloride plastic pipe is glued, and plastic pipes made of polypropylene or polyethylene or composite materials are glued and additionally screwed to the beam with screws strength), in which the connecting part is installed, made in the form of an anchor 75, having the shape of a cylinder, inside of which, on one side, a thread is made into which the connecting fastening means 74 are screwed and secured they are pressed into the beam using pins 76. Then, at each corner point of the frame, the corner elements 73 are fixed. Next, the side beams are inserted between the corner elements, forming the frame of the structure. Formed frames strengthen and form the following.

The proposed nodal connection can be used in a modular design in which wood, metal and concrete are optimally combined.

It should be noted that with an increase in the number of pins, the bearing capacity of the nodal connection increases.

During the tensile testing of the nodal connection (Fig. 6) using a metal anchor (Fig. 8) and a plastic (polypropylene) pipe 71 (Fig. 7), it was found that the unit withstands a force of F = 30 kN. In this case, the gap occurred at F = 32 kN. In this regard, we can conclude that the nodal connection of the proposed design is strong enough to withstand the load.

In FIG. 9 shows a general view of the nodal connection of glued beams.

In FIG. 10 is a cross-sectional view of the nodal connection of glued beams using an anchor with a collet clamp as connecting means.

In FIG. 11 shows an anchor with a collet clamp.

The nodal connection of glued beams consists of a connecting corner element 103 made of metal and connected by a bolt 104 - connecting fastening means with an anchor with a collet clamp - 117 (Fig. 11), which is inserted inside a plastic pipe 101 (for example, polyvinyl chloride or polypropylene, or polyethylene). Inside the anchor 117 (FIG. 11), a cylindrical cone 118 (FIG. 11) is inserted, which, as a result of its movement caused by screwing of the fastening means 104 into the threaded hole inside the anchor, moving along the conical hole, pushes the cylindrical walls of the anchor and thereby enters mesh with plastic pipe 101 and fasten with it.

Inside one of the ends of the anchor (Fig. 11) there is an opening with an internal thread, and several longitudinal cuts and an opening in the form of a cone are made on its other end. A cylindrical cone 118 is inserted inside the anchor.

The design is collected as follows:

First, a plastic pipe 101 is glued into the middle of the glued beam 102 for its entire length, or on its part, into which a connecting part is made, made in the form of an anchor with a collet clamp 117 (Fig. 11), having the shape of a cylinder, inside of which, on one side, it is made thread for screwing the connecting fastening means 104. Then, at each corner point of the frame, the corner elements 103 are fixed by means of fastening means 104, which, when screwed into the anchor 117 (Fig. 11), moves the cylindrical cone 118 along the conical hole of the anchor 117 into the Therefore, the cone 118 presses on the cylindrical walls of the anchor 117, which engage with the plastic pipe 101 (Fig. 10). Next, the side beams are inserted between the corner elements, forming the frame of the structure, the formed frames are strengthened, and the following are formed.

It is important to note that the proposed group of utility models has advantages over the prior art.

Thus, the proposed construction of glued timber with a plastic (polyvinyl chloride PVC, polypropylene, polyethylene) pipe installed in it allows the use of different connecting parts in the proposed design of the nodal connection.

The connecting parts can be made in the form of anchors bolted to the connecting elements, or metal threaded rods inserted inside the plastic pipe and screwed to the connecting elements with nuts, or bolts connecting the connecting element to the glued beam screwed into the thread, cut directly in a plastic pipe 60-100 mm long from each of its ends, when using a thick-walled pipe.

The glued beam is one of its ends adjacent to the connecting corner element, and can be attached to it by one of the proposed fastening means.

If it is necessary to withstand heavy loads, instead of anchors, a metal pin (M20 thread) is inserted inside the plastic pipe, which is screwed to the connecting corner elements made in the form of metal structures located at different ends of the glued wooden beam. Thus, the entire load will be held by a metal stud. This gives us the opportunity to lift large weights and use in mobile building structures.

If it is necessary to withstand a small load, where tensile forces are not required, instead of the anchors of the proposed design, a thread can be made inside a plastic pipe glued into a wooden beam at its ends, for example M24, and a wooden glued beam can be attached to the connecting element, made in the form metal construction directly with corresponding M24 bolts. The connection is strong enough, able to solve this problem.

When conducting tensile and tensile tests of this compound without a metal anchor using a polypropylene pipe, it was found that the pipe ruptures at F = 8 kN.
