Description
Technical Field
The utility model relates to the field of fixed buildings, in particular to a sandwich wallboard.
Background
The curtain wall is an outer wall enclosure system of a building, and a common curtain wall is a single-sided curtain wall, namely, a panel is hung on one side of a metal framework (also called a keel frame) by utilizing metal hanging pieces. Because the double-sided curtain wall has the advantages of small occupied space and attractive appearance compared with a common partition wall, the double-sided curtain wall is an ideal choice because a large space is divided into a plurality of independent spaces.
However, the cross beams in the metal skeleton of the existing curtain wall are basically angle steel, two sets of connecting pieces connected with hanging pieces are required to be arranged on the angle steel for hanging the curtain wall on two sides of the cross beams, and the two sets of connecting pieces are required to be installed in a staggered mode, so that the completely symmetrical decorative effect of the double-sided curtain wall cannot be achieved. Especially, the panel load of the existing curtain wall is not directly acted on the cross beam of the keel frame by the hanging parts, but is transmitted to the cross beam at least through one set of connecting pieces, and the adjusting sites of the front-back, up-down, left-right three-dimensional position relation among the panels are dispersed, so that the hanging system is complex, and the stability is poor.
The patent application with publication number CN 203022169U discloses an I-shaped seam stone curtain wall, which adopts a supporting plate type dry hanging scheme. In the scheme, a steel upright post 10 is fixedly connected with an angle steel beam 20 through a section of angle steel connecting piece 30, and a groove-shaped stone pendant 34 is fixed on the outer side of one right-angle side of the beam 20; the upper and lower flanks of the stone hanging piece 34 are respectively bent upwards, and the hooks on the upper and lower supporting plate hanging pieces 36 are respectively hooked to the upper and lower flanks to form a buckling part 32; the fastening part 32 is provided with an adjusting screw 35, and a hook of the adjusting screw 35 penetrating through the supporting plate hanging piece 36 acts on the upward bending end part of the flank of the stone hanging piece 34. Although all fixing procedures can be finished in advance to facilitate the direct on-site hanging, the scheme of the utility model has the following defects besides the common defects in the prior art: 1. although the adjusting screw 35 can adjust the up and down positions of the stone slabs 41 or 42, the larger the adjusting range is, the shallower the fastening depth of the fastening portion 32 is, which not only greatly limits the adjusting range, but also seriously affects the stability of the curtain wall system; 2. the front and back positions of the stone plates depend on the front and back position relation of the connecting piece 30 and the cross beam 20, so that holes for penetrating fixing bolts on the connecting piece 30 and the cross beam 20 are customized according to the design requirements of customers, the customized workload is relatively large, and the production cost is high; 3. the length of the stone hanger 34 is short, and if the stone panel of the specification used in the original design is in shortage, the specification of the stone panel must be temporarily replaced by changing the distance between the upper and lower cross beams and the distance between the two adjacent stone hangers at the same time, which is troublesome and complex.
The utility model patent application with publication number of CN 103452214A discloses a back bolt stone curtain wall, which is mainly different from the utility model patent with publication number of CN 203022169U in the following three points: firstly, the upper hanging piece 11 omits hooks connected with connecting seams formed on stone plates on the upper and lower supporting plate hanging pieces, and then the upper hanging piece and the lower supporting plate hanging pieces are connected into a whole and fixed on the back of the stone panel 9 by adopting the back bolt 6; secondly, the transverse steel keels 2 are fixed on the side surfaces of the vertical steel keels 1; thirdly, the direction of the mounting hole (long hole) for fixing the angle bracket 3 of the transverse steel joist 2 is vertical to the stone panel 9. The scheme of the patent application of the utility model changes the pallet type dry hanging scheme of the patent of the utility model into a back bolt type dry hanging scheme, so that the problem that the joint of the upper and lower stone panels is slotted to weaken the stone panels can be effectively avoided, but the defect of the patent of the utility model with publication number of CN 203022169U still exists.
