Description

Fixing bolt for curtain wall plate

Technical Field

The utility model relates to a building engineering technical field, in particular to a fixing bolt for curtain board.

Background

The curtain wall is the outer wall enclosure of the building, does not bear the weight, hangs like a curtain, so is also called as a curtain wall, and is a light wall with decorative effect commonly used by modern large-scale and high-rise buildings. The outer building envelope structure or decorative structure consists of a panel and a support structure system, can have certain displacement capacity or certain deformation capacity relative to a main structure, and does not bear the function of the main structure (an outer wall frame type support system is also one type of a curtain wall system).

In the process of installing the curtain wall board, the panel of the curtain wall board is often oversized, after the supporting structure is installed and fixed on a building, the panel vibrates due to the influence of high-altitude wind power, and if the curtain wall board is made of metal materials, the panel surface of the curtain wall board is easy to deform, so that the attractiveness is influenced; if the curtain board uses the toughened glass material, then the face to the toughened glass curtain board causes destruction easily for long-time emergence vibration, and the piece falls to cause the injury to the pedestrian.

Fig. 2 is a schematic front structural view of the present invention.

In the figure: 1. a support bar; 2. an expanding screw head; 3. a cushion pad region; 4. fixing a nut; 5. the handle is rotated.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a fixed bolt for curtain board as shown in fig. 1-2, including bracing piece 1, one section inflation screwhead 2 is installed to the front end of bracing piece 1, inflation screwhead 2 is provided with round inflation hole at the foremost metal cylinder, the rear of bracing piece 1 extends there is one section blotter piece district 3, 1 inside expansion pipe that has the coaxial line of bracing piece, the one end of expansion pipe is provided with quantity the same with the position that inflation hole corresponds, the inflation head that the size matches, the other end of expansion pipe extends out by blotter piece district 3, blotter piece district 3 is thicker than bracing piece 1, and the rear end surface has the round screw thread, there is fixation nut 4 in 3 rear end outsides in blotter piece district, fixation nut 4's screw specification is unanimous with 3 screw specification in blotter piece district, and fixation nut 4 installs a convex rotatory handle 5.

The utility model discloses a theory of operation: reserving a small hole matched with the diameter of the support rod 1 on the surface of the curtain wall board, installing the curtain wall board on the keel frame, drilling a hole on the wall body by using a drill bit with the same specification with the small hole on the surface of the curtain wall board, then separating the fixing nut 4 and the whole body of the utility model, taking the expansion pipe extending out from the rear of the buffer pad area 3 as the part connected with the drill bit, using a drilling machine to drive the rod body part into the wall body through the surface of the curtain wall board, enabling the expansion pipe in the support rod to form a large positive pressure on the outer peripheral surface of the expansion pipe in the axial movement process of the screw thread, enabling the expansion pipe to generate extrusion type deformation towards the expansion screw head 2, enabling the expansion head at the lower end of the expansion pipe to be extruded out from the metal cylinder part of the expansion screw head 2, enabling the expansion head to penetrate through the wall body in the wall body, thereby enabling the tubular part of the utility model to be connected with the wall body and the surface of the curtain wall board to form a stable structure, at this time, the fixing nut 4 is screwed down along the thread direction of the cushion pad area 3, and the installation is completed.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "disposed," "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model discloses the standard parts that use all can purchase from the market, and dysmorphism piece all can be customized according to the record of the description with the drawing.
