Connecting bridge member of concrete external wall

Abstract

The invention relates to a connecting bridge piece of a concrete outer wall, which belongs to the technical field of construction. The connecting bridge parts of the concrete exterior wall are divided into two parts, the outer hollow pipe fitting and the embedded hollow pipe fitting, both of which are thin-walled prefabricated hollow pipes; A connecting plate with holes reserved for fasteners is added; the embedded hollow pipe fittings are provided with protruding teeth, and an outer casing hollow pipe fitting connecting plate with holes reserved for fasteners of the outer jacket hollow pipe fitting connecting plate is arranged at one end. The present invention has a simple structural design, adopts the casing design, utilizes the concave notches of the outer hollow pipe fittings to match the outer convex teeth of the embedded hollow pipe fittings, and the positioning effect of reserved holes, and cooperates with the fasteners to form a good tightness during installation. It has a solid effect, is not easy to loosen, and has good practicability. Compared with the prior art, the product has outstanding substantive features and significant progress.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a connecting bridge piece for a concrete outer wall. Background technique [0002] The external thermal insulation construction technology of cast-in-place concrete external wall means that after the wall reinforcement is bound and before the concrete wall is poured, the thermal insulation board is placed inside the outer mold. After the concrete is poured, the thermal insulation layer and the wall are organically combined. Polystyrene board can be EPS or XPS. When XPS is used, the surface should be roughened, grooved, etc. to enhance the bonding performance, and the matching interface agent should be applied. There are two different connection methods between polystyrene board and concrete: [0003] (1) Network system: the outer surface has trapezoidal grooves and single-sided steel wire grid polystyrene board (EPS or XPS) with inclined wires. Spray the interface agent on...

Problems solved by technology

[0019] In order to solve the above existing technical problems, the present invention provides a connecting bridge for concrete exterior walls, which has a simple structural design and can be produced in a modular manner. It adopts a sleeve design and utilizes the inner concave gap of the outer hollow pipe and the outer surface of the inner hollow pipe. The positioning effect of convex teeth matching and reserved holes can form a good fastening effect with fasteners during installation, which is not easy to loosen and has good practicability. Compared with the existing technology, the product has outstanding The substantive characteristics and significant progress of the system can effectively solve the problems of anchorage and construction difficulties of the integrated slab
