Abstract
The utility model discloses a clamping joist, which comprises a main joist, wherein a hanger rod hole and a mounting hole are arranged on the main joist, clamp positions for hanging an auxiliary joist are arranged on the lower portion of one side wall of the main joist in interval, and the other side wall of the main joist is formed into a longitudinal folding edge, at least one longitudinal fold or pressing mark is arranged on the side wall of the upper portion of the clamp position, and pressing marks can be arranged on the folding position of the upper portion of the side wall of the clamp position in interval. Therefore, a main joist structure with inversed-L shape cross section is formed, because only anchor clamp positions of a light steel joist and square clamp positions for hanging a T-shape joist are arranged on one side of the main joist, and the clamp positions on the other side are concealed, and the structure not only is convenient for installing and adjusting a bolt of the hanger rod hole, greatly saves plates, reduces the weight of the joist, simultaneously, can keep the longitudinal folding resistant force of the main joist through the folding edge on the other side wall, and greatly improves the longitudinal folding resistant force through the longitudinal fold or the pressing mark or the pressing marks arranged in interval on the folding position.
Description
Technical field
The utility model relates to building lifting decoration element, relates in particular to ceiling lifting keel.
Background technology
The lifting of existing ceiling all is to adopt the cassette keel that cooperate with major-minor keel intersection, wherein, the cross sectional shape of main joist is " П " shape, its main body top is provided with boom hole, the main body both sides all in order and correspondingly be arranged with the anchor shape screens that is used to hang rider keel, but find that in long-term production and work progress the keel of this structure are not easy to the installation and the adjustment of suspension rod bolt, the anchor shape screens that its bilateral of while is hung rider keel also exists the raw-material drawback of waste.
Summary of the invention
The utility model purpose provides a kind of cassette keel of one-sided anchor shape screens structure, to overcome the prior art defective.
The utility model is realized in the following manner: this cassette keel comprise main joist, described main joist is provided with boom hole and installing hole, it is characterized in that main joist one lower sidewall is spaced is useful on the screens of hanging rider keel, and another sidewall forms vertical bending edge.
For improvement of the present utility model, be provided with a vertical folding line or impression on the sidewall on described screens top at least, to improve vertical bend resistance power of main joist.
For further improvement of the utility model, the bending place space set impression of described screens side wall upper part is so that further strengthen vertical bend resistance power of main joist.
Described screens comprises spaced lightgage steel joist anchor shape screens and the screens of T type keel, and wherein anchor shape screens top and sidewall are separated.
The technological progress that the utility model is obtained:
Because the only square screens that is provided with the shape screens of lightgage steel joist anchor and hangs T type keel at a side of main joist, and cancelled the screens of another side, promptly form the main joist structure of shape of cross section for " Γ " shape, this structure not only is convenient to the installation and the adjustment of boom hole bolt, save sheet material greatly, reduce the weight of keel, simultaneously the bending edge that forms of another sidewall also can keep vertical bend resistance power of main joist, and the impression that is provided with at interval of vertical folding line of setting up or impression and bending place has also improved vertical bend resistance power of main joist greatly.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
The specific embodiment
As Fig. 1, shown in Figure 2, the main joist of this cassette keel is a dissymmetrical structure, promptly only be spaced and be useful on the anchor shape screens 4 of hanging light steel paired joist and be used to hang T type keel screens 2 in the one lower sidewall, 3 and square screens 5, wherein screens 3 tops and sidewall are separated, be screens 3 downwards double flat to be used for the lifting construction of T type (baking vanish) keel, the sidewall on screens top is provided with a vertical folding line 1 (or impression), this folding line 1 (or impression) is to improve vertical bend resistance power of main joist, the bending place of screens side wall upper part is provided with many places impression 6 at interval, this impression 6 can further be strengthened vertical bend resistance power of main joist, and another sidewall forms vertical bending edge 7, and this bending edge 7 can keep vertical bend resistance power of main joist.
Claims (5)
