Problems solved by technology

However, after the prefabrication of steel bars and concrete in the structural layer of this process is completed, the steel bars cannot be fully lapped when connected, which may bring unsafe hidden dangers to the overall structural safety of the building.
Prefabrication of the unstressed structural layer and cast-in-place structural layer can solve the above problems and save external pouring formwork, but the structural layer is thin and the flexural strength is low, which is prone to breakage during production, transportation, and installation. Common faults that seriously affect the construction period
Although all the use of lightweight aggregate concrete can reduce the weight of the components, but the durability is relatively poor

Embodiment 1

[0032] see Figure 1~2 , in an embodiment of the present invention, a structure and construction method of a ribbed network frame laminated wall, including a prefabricated unit 4, the prefabricated unit 4 includes a concrete prefabricated construction layer 1, an insulation layer 2 and a welded steel grid panel 3, and the concrete prefabricated structure Layer 1 has concrete ribs 8 embedded in the insulation layer 2 vertically or horizontally and vertically. Anti-deformation parts are placed inside the concrete ribs 8 close to the insulation layer 2. A reinforced concrete cast-in-place unit is arranged on the side of the insulation layer 2. 5. The concrete prefabricated structure layer 1 is composed of a layer of lightweight aggregate concrete layer 6 close to the insulation layer 2 and an outer fine stone concrete layer 7. The concrete prefabricated structure layer 1 is composed of a single layer of concrete layer. The anti-deformation part is thin-walled steel 10, the wall t...

Embodiment 2

[0034] see image 3 , In an embodiment of the present invention, a structure and a construction method of a ribbed grid laminated wall, the deformation-resistant member is a bending-resistant steel bar 9, and the diameter of the bending-resistant steel bar 9 is 3mm-12mm.

[0035] The construction process steps are as follows:

[0036] S1: welding and combining the insulation board with grooves, the first steel mesh 11, the second steel mesh 13 and the obliquely inserted web bars 12 to form a steel bar welded grid plate 3;

[0037] S2: place bending steel bars 9 or thin-walled section steel 10 in the groove of the insulation board;

[0038] S3: Pouring the concrete layer of the prefabricated structural layer or successively pouring lightweight aggregate concrete and fine stone concrete to form prefabricated unit 4;

[0039] S4: Binding the steel bars of the reinforced concrete cast-in-place unit 5;

[0040] S5: install the prefabricated unit 4 on one side of the reinforced c...

Abstract

The invention discloses a ribbed net rack superimposed wall structure and a construction method. The ribbed net rack superimposed wall structure comprises a concrete precast structural layer, a heat insulation layer and a reinforced concrete cast-in-place unit, the concrete precast structural layer is provided with a concrete rib protrusion embedded in the heat insulation layer in the vertical direction or the horizontal and vertical directions, an anti-deformation part is placed in the position, close to the heat insulation layer, in the concrete rib protrusion, and the reinforced concrete cast-in-place unit is arranged on one side of the heat insulation layer; the concrete precast structural layer is composed of a light aggregate concrete layer close to the heat insulation layer and an outer fine aggregate concrete layer, the concrete precast structural layer is composed of a single concrete layer, and the anti-deformation part is thin-walled steel; and the concrete precast structural layer contains reinforcing meshes, and a first reinforcing mesh is welded with an oblique-cutting web bar penetrating through the heat insulation layer and a second reinforcing mesh on the other side of the heat insulation layer to form a space net rack. The concrete rib protrusion can increase the stiffness out of plane of the structural layer, and ensure that the precast unit cannot be brokenin the hoisting process.

Description

technical field [0001] The invention relates to a network frame superimposed wall, in particular to a structure and a construction method of a ribbed network frame superimposed wall. Background technique [0002] At present, when reinforced concrete prefabricated components are used for the exterior walls of buildings, the process of prefabricating all concrete sandwich walls is basically used. However, after the prefabrication of steel bars and concrete in the structural layer of this process is completed, the steel bars cannot be fully lapped and connected during connection, which may bring unsafe hidden dangers to the overall structural safety of the building. Prefabrication of the unstressed structural layer and cast-in-place structural layer can solve the above problems and save external pouring formwork, but the structural layer is thin and the flexural strength is low, which is prone to breakage during production, transportation, and installation. Common problems ser...
