Embodiment 1

[0043] Such as figure 1 Said, the present invention provides the connection plate 4 that thickness is 5-10mm, and connection plate 4 comprises upper layer steel bar connection area 1, is arranged on upper layer steel bar connection area 1 top surface length and is 10mm blade portion 1-2, middle layer insulation layer connection area 2 and the lower reinforcement connection area 3, the upper reinforcement connection area 1 is provided with at least two connection holes 1-1 for passing through the reinforcement, and the distance between adjacent connection holes 1-1 is 150mm or 200mm. The lower reinforcement connection area 3 includes a straight or L-shaped reinforcement slot 3-1, a local reinforcing bar 3-2 and a reinforcement binding hole 3-3. There are two reinforcement slots 3-1 and they are arranged at intervals in the lower layer. In the lower part of the reinforcement connection area 3, the distance between adjacent reinforcement grooves 3-1 is 150 mm or 200 mm.

Abstract

The invention discloses a connecting plate, a multiplayer composite heat-preservation wall comprising the same and a construction method of the multiplayer composite heat-preservation wall. The connecting plate comprises an upper-layer steel bar connecting area, a blade part arranged on the top face of the upper-layer steel bar connecting area, a middle-layer heat-preservation layer connecting area and a lower-layer steel bar connecting area, and the upper-layer steel bar connecting area is provided with two or more connecting holes used for allowing steel bars to penetrate; and the lower-layer steel bar connecting area comprises two or more steel bar clamping grooves, local reinforcing bars and steel bar binding wire holes, the two or more steel bar clamping grooves are formed in the lower part of the lower-layer steel bar connecting area at intervals, the steel bar binding wire holes are formed in the positions, close to one side of the middle-layer heat-preservation layer connectingarea, above the steel bar clamping grooves, and the local reinforcing bars are parallelly arranged in the lower-layer steel bar connecting area at intervals. The connecting plate is ingenious in design, simple in structure and good in forming effect. The problems that a fiber reinforced plastic connecting part in the present stage is low in strength and cannot connect thick heat-preservation layers, and a cold bridge is prone to occurring during using of steel are solved.

Description

technical field [0001] The invention relates to the field of connection plate construction, in particular to a connection plate, a multilayer composite thermal insulation wall containing the connection plate and a construction method thereof. Background technique [0002] The prefabricated composite thermal insulation wall has the advantages of good thermal insulation performance and fire prevention, and has a good application prospect in the field of building industrialized exterior walls. [0003] At present, there are two ways to make the insulation layer of the composite thermal insulation exterior wall: one is to lay block insulation materials such as rock wool, extruded board, and vacuum insulation board; the other is to lay pourable insulation materials such as microporous concrete. [0004] The connection of each layer in the composite wall is the key of the composite thermal insulation wall. At this stage, conventional connection methods include fiber-reinforced pl...
