AI Technical Summary

Problems solved by technology

Fiber-reinforced plastic connectors do not transmit or can only partially transmit the shear force between the inner wall and the outer concrete slab. The connector can only be used in the enclosure wall and cannot be used in the load-bearing wall
(2) Poor fire resistance
The prefabricated concrete sandwich insulation wall with this connector is prone to fire safety hazards
(3) The production process is more complicated and the price is higher
The price of fiber-reinforced plastic materials per unit mass is about 8 to 12 times that of steel bars. High production costs hinder the promotion and application of fiber-reinforced plastic connector products in construction projects
(4) The anchoring performance is poor, the installation is inconvenient, and the construction efficiency is low

Embodiment 1

[0049] see figure 1 , this embodiment discloses a prefabricated sandwich insulation wall, comprising an outer wall panel 1, a middle insulation layer 2, an inner wall panel 3 and a connector, and the middle insulation layer 2 is sandwiched in the inner wall panel by the connector. 1. In the middle of the outer wall panels, the connectors are prefabricated sandwich insulation wall steel-fiber plastic composite connectors.

[0050] see Figure 2 to Figure 9 , and please combine figure 1 , the prefabricated sandwich thermal insulation wall steel-fiber plastic composite connector includes a columnar connector 5, a connecting base 6 and a connecting cap 4, and the connecting base 6 and the connecting cap 4 are respectively fixedly connected to the columnar connector 5 the two ends; the column connector 5 includes a metal column 10 , a fiber cloth 13 wrapped around the metal column 10 , and a fiber bundle 15 wound on the fiber cloth 13 along the axial direction of the metal column...

Embodiment 2

[0061] read on Figure 1 to Figure 9 , this embodiment discloses a method for manufacturing a steel-fiber plastic combined connector for a prefabricated sandwich thermal insulation wall, including:

[0062]Making the columnar connector 5 specifically includes: first evenly coating epoxy resin on the fiber cloth 13, then densely wrapping the metal column 10 with the fiber cloth 13 coated with epoxy resin, and finally covering the metal column 10 with fiber cloth impregnated with epoxy resin. The bundle 15 is wound circumferentially on the metal column 10 wrapped with the fiber cloth 13 at an angle of 30°-45° to the axial direction of the metal column 10, wherein the fiber cloth 13 is carbon fiber or basalt fiber cloth, and the fiber cloth 13 is The bundles 15 are carbon fiber or basalt fiber bundles. The purpose of wrapping the fiber cloth 13 outside the metal post 10 is to prevent the metal post 10 from heat conduction and prevent the metal post 10 from being corroded by mois...

Embodiment 3

[0069] read on Figure 1-Figure 9 , this embodiment discloses a method for manufacturing a prefabricated sandwich thermal insulation wall, comprising the following steps:

[0070] In step 1, a number of connectors are made by using the method in embodiment 2.

[0071] Step 2, arranging the steel bars of the inner wall panel 3 and pouring concrete on the inner wall panel 3 .

[0072] Step 3, laying an intermediate thermal insulation layer 2 on the inner wallboard 3, reserving several intervals on the intermediate thermal insulation layer 2 to set connector holes for inserting the connectors, and the intermediate thermal insulation layer 2 has a certain The elasticity is usually extruded polystyrene foam board (XPS), polystyrene board (EPS), polystyrene, polyurethane, rock wool, glass wool, etc.

[0073] Step 4, inserting the connector so that the connection base 6 is located in the concrete of the inner wall panel 3 , and the connection cap 4 is located above the middle insul...

Abstract

The invention discloses a steel-fiber plastic combined connector, a prefabricated sandwich thermal insulation wall and a manufacturing method. The connector comprises a columnar connecting body, a connecting base and a connecting cap, and the connecting base and the connecting ca are fixedly connected to the two ends of the columnar connecting body respectively. The columnar connecting body comprises a metal column, fiber cloth wrapping the outer side of the metal column and a fiber bunch axially wound on the fiber cloth along the metal column. The connecting base comprises a metal base body and a plurality of metal rib angles, and the metal rib angles are distributed on the lateral surface of the metal base body at intervals. The connecting cap comprises a metal cap body, metal inserting ribs and a plastic cap sleeve. The metal inserting ribs transversely penetrate through the metal cap body, and the plastic cap sleeve wraps the exposed part of the metal cap body and the exposed parts of the metal inserting ribs. The connector has the advantages of being high in anti-shear strength, low in processing cost, high in fire resistance, low in heat conduction coefficient, convenient and fast to install and the like. The prefabricated sandwich thermal insulation wall has the advantages of being high in anti-bending performance and anti-shear performance, good in thermal insulation effect, low in manufacturing cost, long in service life and the like.
