Description

Clamp for detecting glass felt

Technical Field

The utility model relates to the technical field of building material detection, in particular to a clamp for glass felt detection.

Background

The glass cotton felt is a building heat-insulating energy-saving material. GBT 10294-2008 "method for measuring the steady-state thermal resistance and the related characteristics of heat-insulating materials" provides a method for detecting glass wool felt. During detection, the glass wool felt needs to be vertically placed in the detection equipment and placed between the heating plate and the cooling plate of the detection equipment, the heating plate is fixed in the detection equipment, the cooling plate can move in the detection equipment, and the glass wool felt is extruded through the movable cooling plate, so that the glass wool felt is guaranteed to be closely attached to the heating plate and then heated, and the heat conductivity coefficient of the glass wool felt is measured.

As the glass cotton felt is soft and is in a bulked shape, larger deformation is easy to generate during extrusion, the thickness of the deformed glass cotton felt is reduced, the density is increased, the states of the glass cotton felt in actual use and detection are inconsistent, and the detection result is easy to reflect the state in actual use.

Disclosure of Invention

The utility model provides a clamp for detecting glass felts, which aims to ensure that a cooling plate and a heating plate can be tightly attached to the glass felts, and simultaneously has the effect of fixing thickness and clamping the glass felts, thereby improving the accuracy of detection results.

The utility model is realized by the following technical scheme: the utility model provides a glass felt detects and uses anchor clamps, includes bottom plate and frame, the bottom plate with the bottom sliding connection of frame, just the bottom plate can follow the frame bottom and take out, the frame is the fretwork form.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

in this scheme bottom plate and frame combine each other, through placing the glass felt in the frame, because the frame is the fretwork form, the bottom plate can avoid placing the glass felt in the frame and drop. The thickness of the glass felt placed in the frame is higher than that of the frame, so that after the glass felt is clamped, the frame is vertically erected, two ends of the glass felt are respectively opposite to the heating plate and the cooling plate in the detection equipment, then the bottom plate is pulled out from the bottom of the frame, and the cooling plate is extruded towards the direction of the glass felt.

Because the thickness of frame is unchangeable, can play the effect of fixed thickness centre gripping to the glass felt, offset the back with the both ends of frame when hot plate and cooling plate, can play the extruded effect of fixed pressure to the glass felt, avoid appearing excessively extruding the glass felt, simultaneously under the effect of blockking of frame tip, can enough ensure the closely laminating of glass felt and hot plate and cooling plate, can not produce too big extrusion force to the glass felt again and lead to the glass felt to warp seriously, thereby avoid causing the state inconsistent when in actual use and when detecting, and then can simulate actual use environment more truly, thereby make the testing result more have the guidance nature.

The thickness of glass cotton felt is slightly higher than the frame during the in-service use, and with the bottom plate back of taking out, when cooling plate and hot plate centre gripping glass cotton felt, glass cotton felt can slightly warp, can ensure that glass cotton felt closely laminates with hot plate and cooling plate.
