In order to solve the problem that the existing building back support structure is inconvenient to deal with the position such as an elevator shaft or an inclined cross beam 1, the invention provides a building back support frame, as shown in fig. 1-4.

A building back-to-top support frame comprises a cross beam 1 for supporting a top building structure and two upright posts 2 connected to two ends of the cross beam 1 and used for supporting the cross beam 1, wherein the upright posts 2 sequentially comprise a bottom plate 2a and an upright post body 2b detachably fixed on the bottom plate 2a from bottom to top, a lifting device 2c is installed at the top of the upright post body 2b, and a U-shaped connector 2d is fixed at the top of the lifting device 2c and used for connecting and supporting the cross beam 1; the connector 2d at the top of the left upright is hinged with the cross beam 1, the connector 2d at the top of the right upright is hinged with a slide rail 2d1, and the cross beam 1 is slidably arranged in the slide rail 2d1 and can slide in the slide rail 2d1 along the axis of the cross beam 1; the upright post body 2b comprises a plurality of standard sections 2b1 spliced end to end, and the standard sections 2b1 are detachably and fixedly connected through bolts.

Utilize two stands 2 to support crossbeam 1, support the building through crossbeam 1 and set up on the one hand and compare in red bearing structure in full hall simpler, two stands 2 can set up at the both ends of weighing simultaneously, become beam 1 simply supported structure with crossbeam 1, utilize crossbeam 1 to support, the middle part of crossbeam 1 can be unsettled stride across the elevator well.

Simultaneously two stands 2 all are connected with crossbeam 1 through elevating gear 2c, are convenient for adjust the height that accurate control supported, and one of them stand 2 is the left stand in figure 1 simultaneously and is connected with crossbeam 1 is articulated through the U type connector 2d at top, and crossbeam 1 can rotate around the articulated shaft. Meanwhile, the cross beam 1 can rotate on another stand column 2, namely the right stand column, and can slide along the connector 2d on the right stand column, so that on one hand, when the pitch angle of the cross beam 1 is adjusted, the length difference of the cross beam 1 at different inclination angles is compensated, the stand column 2 is prevented from inclining, and on the other hand, the span of the cross beam 1 is convenient to adjust.

The height of the cross beam 1 can be adjusted in a large range by changing the number of the standard sections 2b1 of the upright posts 2, and the height can be adjusted by the lifting device 2c when the height is accurately adjusted in a small range.

Therefore, the bottom plate 2a can be stably placed on the steel plate on the ground, can be fixed through the ground embedded anchor bolts, and can also be fixed by utilizing self-weight matching friction. The pillar body 2b is detachably and fixedly installed on the bottom plate 2a, wherein preferably a projection is provided on the bottom plate 2a, the projection is provided with a bolt hole, and then the standard knot 2b1 is detachably fixed with the bolt hole on the projection through a bolt. The lifting device 2c may be a hydraulic cylinder or a jack, or an electric lifting device 2c may be used. Preferably, the top of the upright post body 2b is provided with a mounting hole; the lifting device 2c comprises a screw 2c1 and a lifting nut 2c2 mounted on the screw 2c1, the lower end of the screw 2c1 is arranged in the mounting hole, the upper end of the screw is fixedly connected with a U-shaped connector 2d, and the lifting nut 2c2 is pressed on the upright post body 2b and is used for supporting the screw 2c 1. As shown in fig. 3 and 4, the nut screw 2c1 is turned to move up and down, thereby moving the beam 1 up and down.

Preferably, the cross beam 1 is made of I-shaped steel or H-shaped steel. The clamping groove is clamped on the lower flange of the I-shaped steel or the H-shaped steel. The connector 2d at the top of the left upright post is hinged to the web plate of the cross beam 1 through a rotating shaft which is horizontally arranged and perpendicular to the cross beam 1.

As shown in fig. 4, the cross beam 1 has flanges protruding to both sides, two top ends of the U-shaped connector 2d on the top of the right upright are respectively provided with a slide rail 2d1, the slide rail 2d1 is provided with a slot mutually matched with the flanges of the cross beam 1, the flanges are slidably disposed in the slot, and the slot openings of the two slide rails 2d1 are disposed opposite to each other.

The standard knot 2b1 is a rectangular metal frame structure, the upper and lower surfaces of the standard knot 2b1 are provided with reinforcing ribs in the horizontal direction at the corners, and the reinforcing ribs are provided with bolt holes for mounting bolts.

The pressure resistance of the standard section 2b1 of the steel frame is far greater than that of a common steel pipe, so a plurality of cross beams 1 are arranged on the upright post 2 in order to enlarge the supporting area, and the cross beams 1 are parallel to each other. And more preferably two as shown in figure 2. Wherein the height of the standard knot 2b1 may comprise a plurality of heights. The combination is carried out according to the actual use condition.

The working mode of the invention is as follows: firstly, two bottom plates 2a are installed in place, and then the upright posts 2 are installed on the floor to arrange the cross beam 1.

When the supporting height needs to be adjusted in a large range, the number of the standard knots 2b1 can be changed, or the standard knots 2b1 with different heights can be replaced; the precise adjustment is required to rotate the lifting nut 2c2 to precisely adjust the height of the beam 1. The span of the beam 1 can be adjusted because the upright 2 and the beam 1 can be connected in a sliding way.

Meanwhile, when the inclined building beam is supported, the heights of the two upright posts 2 of the supporting beam 1 are different. The included angle between the beam 1 and the upright post 2 is changed, and the vertex distance between the two upright posts 2 is different when the height is adjusted. Thus, both uprights 2 are rotatably connected to the cross member 1, and one of the uprights 2, i.e. the right upright in fig. 2, is also slidably connected to the cross member 1 to compensate for the difference in the distance between the two vertices. Specifically, a rotating slide rail 2d1 is arranged at the top of the screw rod 2c1 of the right upright post, and then the cross beam 1 is arranged in the slide rail 2d1 in a sliding way. When the angle of the beam 1 is adjusted, the distance difference between the vertexes of the two columns 2 is compensated by the sliding of the beam 1 in the slide rail 2d 1.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
