Anchoring part for fixing concrete roof and roof waterproof and heat-insulating structure

Technical Field

The utility model relates to the field of building heat preservation and water prevention, in particular to an anchoring part for fixing a concrete roof and a roof waterproof heat preservation structure.

Background

At present, when the building construction, can set up heat preservation and waterproof layer on the roofing basic unit, in order to play the effect that the house keeps warm and insulates against heat, give sound insulation and leak protection water, if adopt the insulation material of panel class this moment, in order to guarantee the whole quality of building, except using cement mortar to paste the heat preservation on the roofing, still need use special anchor assembly to link heat preservation and wall body in an organic whole, and the anchor assembly of most common use is the concrete screw, but when directly using concrete screw fixed insulation layer, need bore the hole that is less than the screw size on the basic plane in advance, increase process and labour cost, and because the concrete belongs to rigidity brittle material, its self is easily expend with heat and contract with cold, the pulling force between screw and the concrete basic unit is little, influence fixed effect. In addition, the roof of the building is the most affected part by the outdoor heat action in the peripheral structure of the building, if the screw directly contacts with concrete, the cold bridge or the heat bridge phenomenon is easy to generate, the heat loss is generated, and the air conditioning, the heating load and the energy consumption of the building are increased.

Based on the defects, the mechanical anchoring part is formed by a screw and a plastic expansion pipe with a disc, the anchoring part mainly depends on the friction force between the plastic expansion sleeve and a wall body, materials can creep along with the passage of time, the extrusion force between the plastic expansion sleeve and a roof base layer is reduced, the roof waterproof and heat-insulation structure is easy to loosen or even fall off, the heat-insulation effect of the plastic expansion pipe is still not ideal, and the cold bridge or the heat bridge phenomenon can still occur at the nut of the screw when the mechanical anchoring part is used.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome at least one defect (deficiency) of the prior art, and provides an anchoring part for fixing a concrete roof and a roof waterproof and heat-insulating structure, which can effectively avoid the generation of cold bridge or hot bridge phenomenon, enhance the heat-insulating effect, increase the drawing force between the anchoring part and the concrete and ensure that the fixing is firmer.

The utility model adopts the technical scheme that an anchoring part for fixing a concrete roof is provided, which comprises a fixing screw, a sleeve, a gasket and a heat-insulating rod, wherein the heat-insulating rod is arranged in the sleeve, the gasket is arranged at one end of the sleeve and is provided with a through hole communicated with the sleeve, the other end of the sleeve is provided with an expansion part, the expansion part is of a closing-up structure and comprises a plurality of expansion pieces which are spliced with each other, the fixing screw is arranged in the sleeve, one end of the fixing screw is arranged in the heat-insulating rod, and the other end of the fixing screw is arranged in the expansion part.

In this technical scheme, when the sleeve pipe was put into to set screw, set screw propped open the inflation piece, make the sleeve pipe can fix in the concrete of pouring, the inflation portion is the binding off structure that the cross section gradually becomes little, can restrict the biggest degree of depth that stretches out of set screw, can also prevent that set screw from breaking away from the sleeve pipe from the below, and set screw is wrapped up by the sleeve pipe this moment, make set screw and concrete basal layer not have direct contact, and sheathed tube heat conductivity is poor than set screw, can make anchor assembly have certain heat insulating ability, and the one end through insulating bar parcel set screw, can further keep warm in order to form the bridge cut-off to set screw, and then strengthened the heat preservation effect of roofing.

Further, the gasket is a non-perforated metal gasket made of a ferromagnetic material and comprising an upper surface far away from the expansion part and a lower surface close to the expansion part, and the upper surface is provided with a thermal adhesive coating.

Preferably, the spacer is circular.

In the technical scheme, ferromagnetic materials such as iron, steel, nickel and partial alloys of the metals are adopted, a ferromagnetic non-perforated metal gasket can be used for welding a high-molecular waterproof layer and a gasket by utilizing electromagnetic induction, in the construction process, a magnetic device can accurately position an anchoring piece shielded by the high-molecular waterproof layer, when the magnetic device is arranged at the position of the gasket and started, the gasket generates a magnetic heating effect, the high-molecular waterproof layer is welded with the gasket through a thermal adhesive coating, and after welding is finished, a cooling roller is arranged at the position of the gasket to quickly cool the gasket so as to strengthen the welding effect, so that the connecting effect of the anchoring piece and the high-molecular waterproof layer is better; compared with the traditional gasket, the non-perforated metal gasket does not need to perforate the high polymer waterproof layer, can be uniformly welded with the waterproof layer, improves the wind uncovering resistance of the high polymer waterproof layer, avoids the water seepage of the high polymer waterproof layer due to perforation, and enables the roof to be more attractive.
