Description

I I

The invention relates to the construction, mainly to devices for fastening heat insulating plates to the surfaces of building envelopes, and is an improvement of the invention according to the author. St. No. 975944.

The aim of the invention is to increase the reliability of fastening.

Fig, 1 shows the attachment of a heat insulating plate to a concrete base; 2, the same, in the case of using the device of increased factory readiness; in FIG. 3 — FIG. 4 — the node T in FIG. 3; figure 5 - node II in fig.Z; figure 6 is a cross-shaped slot of the head; Fig. 7 shows a perforated mounting plate with a cone-shaped recess cut into spring segments; on Fig - section aa in Fig.7; Fig, 9 - plate retainer; figure 10 is a section bB in figure 9.

The device consists of a pin 1, a perforated mounting plate 2 and a plate retainer 3. Pin 1 (FIG. 3) has a pointed end 4 (FIG. 4) and a head 5 (FIG. 5) with a cross-shaped slot 6 (FIG. B). Pin 1 is provided with threaded thread 7 (FIG. 3). The thread 7 is made with an angle of 60 °, two-way from the top of the pointed end to the diameter transition at the end of the support head 5. The pointed end 4 is formed when threading.

The parameters of the thread, the cross-head and the pointed end of the pin 1 in order to unify the technological process, the tool and the equipment for manufacturing are unified by self-drilling self-cutting screws.

Perforated mounting plate 2 is made of thin-sheet

zincor) shogch) steel rolled tolt to 0.7 mm. The recess in the plate under the head 5 pin is made in the form of a cone in the shape of the head 5 with a version 8 at the apex of the cone, equal to the internal diameter of the thread of the pin.

The plate retainer 3 is also made of galvanized steel sheet steel with a thickness of up to 0.7 mm. In the center of the latch clamp recess is made in the form of a cone with a hole 9 at the top equal to the inner diameter of the thread pin 1.

The sequence of fastening the heat insulating plates 10 to the building structures 11 is as follows: on the perforated mounting plate 2 with the rod 1 inserted into the hole 8, put a quick-hardening mastic 12 with a spatula and press it to the surface of the building structure. The mastic 12 fills the hole 13 of the plate 2 in the form of extruded cylindrical rods 14, which clutch the fastening device with the building structure,

After fixing the pin I with a perforated mounting plate 2 to the building structure, a heat insulating plate 10 is punched onto it and pressed with a plate retainer 3. the thread diameter of the pin 1, the edges of the holes abut against the surface of the thread and they are securely fastened and secured in a predetermined position.
