Embodiment 1

[0046] Such as Figure 1~Figure 6 As shown, the present invention is a support structure for the composite beam-slab connection of the assembled structure, including the support frame 3 arranged on both sides of the composite beam 5, the adjusting bolt 4 provided between the support frame 3 and the composite plate 1 and Support plate 6, the support frame 3 is arranged three side by side along each side of the laminated beam 5, the section of the support frame 3 is an irregular frame, and its right-angled sides correspond to the laminated beam 5 and the laminated plate 1 respectively, and the relative composite beam 5 Bolt connection reserved holes are provided on the right-angle side of the side, and are connected to the embedded nut 2 provided on the side of the composite beam 5 by bolts; They are connected by adjusting bolts 6, and the height of the supporting plate 6 is adjusted by adjusting the adjusting bolts 4 between the supporting plate 6 and the supporting frame 3 dur...

Embodiment 2

[0062] The difference between this example and Example 1 is that in this example, the embedded nut 2 provided on the composite beam 5 in this example is provided with a U-shaped rib 7 on the outer periphery, and the angle α inclined relative to the horizontal plane is 30°. What the support plate 6 of this example adopted was a channel frame made by welding steel plates. Such as Figure 10 , Figure 11 As shown, there is a stopper 8 at the end of the embedded nut 2 described in this example that is not connected to the bolt, and the stopper 8 is arranged in a cross-shaped structure along the circumference of the end, which is convenient for installation and fixation.

Embodiment 3

[0064] The difference between this example and Example 1 is that the outer periphery of the embedded nut 2 provided on the composite beam 5 in this example is provided with U-shaped ribs 7 , and the angle α inclined relative to the horizontal plane is 40°.

Abstract

The invention provides a prefabricated composite beam-plate connection support device with height difference on top of the plate and an installation method thereof. The prefabricated composite beam-plate connection support device with the height difference on top of the plate is characterized in that the prefabricated composite beam-plate connection support device comprises support frames, adjustment bolts and support plates, wherein the support frames are disposed on one side of a side beam and both sides of an intermediate beam, and the adjustment bolts and the support plates are arranged between the support frames and a composite plate; three frames with irregular cross sections are arranged side by side on the support frames along one side of the composite beam; right-angle sides of the frames correspond to a composite beam and a composite plate; bolt connection holes are arranged on the right-angle sides, relative to one side of the composite beam, of the support frames; embeddednuts are connected to the composite beam through bolts; the adjustment bolts are connected to the right-angle sides, relative to the composite plate, of the support frames. The prefabricated compositebeam-plate connection support device with the height difference on top of the plate and the installation method thereof have the advantages of lengthening lap length with the embedded nuts connectedto the side of the beam side, having good mechanical properties with an adjusting template bracket connected at the top, and meeting the requirements of lap precision.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to an assembled composite beam-slab connection support device and an installation method with a height difference at the top of the slab. Background technique [0002] With the increasing development of prefabricated buildings, the connection of various components of prefabricated buildings will also become frequent and important. In the connection of prefabricated building structural components, composite beam-slab connection is a very common existence. In this connection form, one end of the laminated slab is lapped on the edge of the laminated beam, the upper part of the slab is hoisted by a crane, and the bottom is supported vertically. [0003] However, there are three main problems in the composite beam-slab connection: [0004] First, the problem of the length of the support of the laminated plate. As far as composite beams are concerned, the protec...
