Description

Technical Field

[0001] The utility model relates to a thermal insulation floor reinforcement device, belonging to the technical field of building construction. Background Art

[0002] The insulation layer of ordinary insulated concrete floors is relatively thin, and the deadweight of the concrete on the insulation layer is sufficient to ensure that the insulation layer will not deform and cause cracking and warping of the concrete layer. However, for insulated concrete floor projects with a thicker insulation layer, since the insulation layer is thicker, if the concrete on the insulation layer is relatively thin, the insulation layer is very easy to deform under construction loads or long-term environmental effects, resulting in warping, cracking and hollowing of the concrete surface layer, affecting the construction quality and appearance of the concrete floor. Therefore, it is necessary to use reinforcement devices to reinforce the insulated floor.

[0003] The comparison patent document announcement number is: "CN208777760U, an ultra-thick thermal insulation floor reinforcement device, comprising a concrete base, an insulation layer is arranged on the concrete base, a concrete surface layer is arranged on the insulation layer, a steel mesh is pre-embedded in the concrete surface layer, upper mounting holes are opened at both ends of the upper surface of the concrete surface layer, lower fixing holes are opened at both ends of the concrete base, expansion bolts are placed in the lower fixing holes, the upper ends of the expansion bolts pass through the insulation layer, the concrete surface layer and the steel mesh in turn and are located in the corresponding upper mounting holes, one end of the expansion bolt located in the upper mounting hole is locked by a nut, a fixing gasket is padded below the nut in the upper mounting hole, and the upper mounting hole is filled with grouting material."

[0004] The above patent still has the following problems in actual use: although the patent can be used for daily reinforcement of insulated floors, in actual use, the expansion bolts only rely on the expansion head for pressurization. When the temperature of the insulation layer changes too much, it is still easy for the reinforcement device to loosen due to thermal expansion and contraction, which makes the reinforcement device unstable in use. In addition, only a wrench can be used to tighten the bolts, so there are fewer adapter tools for the reinforcement device, which limits the use of the reinforcement device. Utility Model Content
