Connecting bridge member of concrete external wall

Abstract

The invention relates to a connecting bridge member of a concrete external wall, and belongs to the technical field of buildings. The connecting bridge member of the concrete external wall is dividedinto a sleeving hollow pipe fitting and a sleeved hollow pipe fitting which are both thin-walled prefabricated hollow tubes. A concave notch is formed in the sleeving hollow pipe fitting. The outer wall of the sleeving hollow pipe fitting is provided with a thread. A connecting plate with a fastener reserved hole is added according to engineering actual conditions. A protruding tooth is arranged on the sleeved hollow pipe fitting. A sleeving hollow pipe fitting connecting plate with a sleeving hollow pipe fitting connecting plate fastener reserved hole is arranged at one end of the sleeved hollow pipe fitting. The connecting bridge member is simple in structural design; by means of the design of pipe sleeving, by means of the effect of the meshing of the concave notch of the sleeving hollow pipe fitting and the protruding tooth of the sleeved hollow pipe fitting and the positioning of the reserved holes, in cooperation with fasteners during installation, a good fastening effect is formed, a loosening phenomenon can not easily happen, and the connecting bridge member has good practicability; compared with the prior art, the product has outstanding practicability and makes a remarkable 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
