Description

Technical Field

[0001] The utility model relates to the field of building structure connectors, in particular to a detachable heat-proof bridge connector embedded in a concrete slab. Background Art

[0002] It is often necessary to hang objects at the bottom of the composite slab or steel truss floor deck (i.e., metal connectors partially embedded in concrete, such as metal connectors used to enable the steel truss floor deck to be removed later). These are usually installed before the concrete is poured on the composite slab or steel truss floor deck. Then, after the concrete is poured on the composite slab or steel truss floor deck, the building user can choose to manually cut off the part that is exposed below the composite slab or steel truss floor deck. However, these partially embedded connectors installed in the composite slab or steel truss floor deck are usually made of steel. When the part below the floor slab is manually cut off, the cross section of the steel connector and the concrete will be directly exposed to the air at the junction. The heat in the air will be conducted to the interface between the connector and the concrete along with the steel. This area is prone to thermal bridges during the later use of the building, and is prone to mold and condensation. Utility Model Content

[0003] In view of the problem of heat bridges caused by direct contact between steel connectors and concrete in the prior art, the utility model provides a detachable heat-bridge-preventing connector embedded in a concrete slab.

[0009] Preferably, the outer side of the second part is stepped, and the bottom of the matching piece is provided with a first boss that matches with the step of the second part.

[0010] Preferably, a mounting piece is provided between the connecting piece and the heat insulating piece, the mounting piece is embedded in a mounting groove formed by combining the first part and the second part, and the connecting piece and the mounting piece are detachably connected.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model discloses a detachable heat-proof bridge connector embedded in a concrete slab. The heat-insulating member is disposed between the fixing member and the connector to block the direct contact between the concrete and the external connector, thereby avoiding the heat bridge phenomenon between the concrete and the connector, and further preventing the mold and moisture phenomenon of the building structure. At the same time, the fixing member and the matching member are used to strengthen the connection between the connector and the concrete, thereby ensuring the connection strength and stability.

[0017] Furthermore, the use of a polygonal mating end can ensure the connection with the mating end and prevent the mating end from rotating. The polygonal mating piece is to ensure the position of the mating piece in the concrete. Compared with the circular one, the polygon helps to increase the friction between the mating piece and the concrete, thereby further ensuring the stability of the connecting piece.

[0018] Furthermore, the thermal insulation pad is divided into a first part and a second part, which are separately arranged for ease of installation. The first part and the second part fully wrap the top of the connector. Since the first part and the second part are both made of elastic material, the connector can be completely isolated from the concrete.

[0019] Furthermore, the stepped first and second parts are both for ensuring the connection strength between the connecting piece and the matching piece, and through cooperation with the first boss and the second boss, both the complete blocking of the thermal bridge and the connection strength can be ensured.
