Background technique

At present, with the development of the world curtain wall technology, the unit curtain wall technology has been promoted. Due to the different size of the curtain wall unit, the wind pressure areas of the buildings are different. If all the curtain wall units are connected by a single point, it will inevitably lead to the requirements of the large wind pressure zone. Large, it will cause material waste. Therefore, it is necessary to use wind-resistant pressure fittings to ensure that most parts use the same standard size mullion to unify the indoor building effect and save costs. There are two main types of traditional wind-resistant connectors. One is to use a hanging type: a main force-receiving member is fixed on the civil construction beam at a portion where the wind-resistant pressure connection member is required, and a belt is fixed on the unit plate. A pendant with a vertical long slot, which is mounted at the same time as the load-bearing connector when installing the unit block. The disadvantage of this type of connection is that the positioning requirements of the main force-receiving members that are previously attached to the civil construction beam are very strict. Once the positioning deviation occurs, the unit plate cannot be installed smoothly: The second is to use the connecting bolt and the sleeve and the connecting piece long hole. In combination with the realization of the upper and lower telescopic forms, the drawbacks of this form are: firstly, it is difficult to install the bolts under the civil construction beam of the casing and the connecting piece, and secondly, when two or more bolts are used to resist the wind pressure, the connection will be made. The size of the piece is increased, and the space under the soil beam is excessively occupied. The same problem exists in the above two kinds of pendants: the stile joints are generally installed on one side, and the joints are thickened due to the asymmetry of the force, and the material is wasted. Summary of the invention

The object of the present invention is to provide a unit curtain wall anti-wind pressure connecting member, which solves the problems of strict hanging positioning requirements, large material waste materials and the like in the prior art, and the structure thereof is compared with the traditional wind-resistant connecting member. The design is reasonable, the manufacturing is easy, the on-site installation operation is convenient and smooth, the adjustment is simple, the occupied space is small, and the material cost and installation cost are significantly saved.

The technical solution adopted by the invention is that the unit curtain wall wind-resistant pressure connecting member comprises a hanging member fixed on the curtain wall unit plate and a main force-receiving member fixed on the soil building beam, and the technical point is: the hanging piece adopts a few a "shaped member" and fixed to the side of the main mullion of the plug-in vertical frame on the curtain wall unit plate by a tapping pad and a connecting bolt, wherein the main force-receiving member adopts an L-shaped profile in which the long and short sides are vertically arranged with each other. a waist-shaped hole is arranged along the longitudinal direction thereof, and a groove-shaped through hole matching the outer contour of the figure-shaped member is arranged along the short side direction thereof, and the figure-shaped member is set in the groove-shaped through hole of the main force receiving member, and is formed along the groove shape The through hole slides, and the main force-receiving member is fixed to the civil construction beam by a T-bolt inserted into the buried beam groove type embedded in the waist hole.

The end portion of the main force-receiving member is provided with a tooth surface, and the tooth-shaped gasket matched with the tooth surface is assembled on the T-bolt of the buried beam type embedded member, and the main force-receiving member is buried by the groove type inserted into the waist hole T-bolts and toothed washers on the parts are fixed with the civil beams Together.

Advantages and positive technical effects of the present invention are: Since the present invention is composed of two main members: the first member is a zigzag member, and the two wings that can be engaged with the main force receiving member are provided, and the embedded connecting bolt is skillfully designed. The groove of the head, the component itself is symmetrical design, which can ensure the uniform force of the wings. The component is pre-installed on the panel of the curtain wall unit; the second component is the L-shaped main force component connected with the civil beam, the short side and several The glyph members are in-line fit, and the vertical direction can be freely slid, while the other directions can all restrict their movement. In the field installation, only the main force-receiving members need to be slid under the civil construction beam, and the lateral adjustment provided by the trough embedded parts is provided. The main force-receiving member can absorb the civil construction error in all directions, and can allow the unit plate to have a large stroke expansion and contraction, thereby solving the problems of strict positioning requirements of the hanging frame and large waste material of the prior art. Compared with the traditional anti-wind pressure connecting piece, the main force-receiving member can be finally installed and adopts the sliding-in structure, so the structure design is reasonable, the manufacturing is easy, the on-site installation operation is convenient and smooth, and the adjustment is simple and easy; Small, more widely applicable; Significant savings in material costs and installation costs, especially for foreign countries with high labor costs, such connectors are more competitive.
