Description

Sand paste non-slip insulation board

technical field

The utility model relates to a thermal insulation board, in particular to a thermal insulation board used for heat insulation under a lining concrete layer in river embankment construction.

Background technique

In large-scale river embankment construction projects, in order to avoid cracking of the lining concrete on the surface of the river embankment due to the large difference in water temperature and ground temperature, an insulation layer is provided between the waterproof layer under the surface of the embankment and the foundation. Insulation extruded boards are often used as the layer. During the construction process, the concrete lining on the surface of the embankment and the waterproof layer are bonded together. Since the existing insulation extruded boards are all smooth, the surface roughness of the extruded boards is not enough, making it There cannot be enough friction between the extruded board and the unsolidified concrete and the waterproof layer will fall off from time to time, resulting in the failure of the construction. At present, there are two ways to solve the above problems: one is during the construction process Use nails to fix the waterproof layer and the extruded board together. Although this method solves the above problems to a certain extent, the waterproof layer is destroyed after the nails are nailed in, making it lose its original waterproof effect. Another method It is to mill grooves on the surface of the extruded board. This method also solves the problem of the outer lining falling off to a certain extent, but this method causes damage to the extruded board itself and reduces the strength of the extruded board. Fracture phenomenon takes place easily, and, in construction process, the phenomenon that the external lining layer of river embankment comes off still occurs from time to time, and above-mentioned two kinds of methods all do not fundamentally solve the above-mentioned problem.

Utility model content

The purpose of the utility model is to provide a sand-pasted anti-skid thermal insulation board whose surface roughness is increased according to actual needs.

In order to achieve the above object, the utility model adopts the following technical scheme: a sand-pasted anti-slip heat preservation board, including a heat preservation board body, an anti-slip sheet is pasted on the surface of the heat preservation board body, and the anti-slip sheet includes a flexible base cloth sheet, The front side of the base cloth sheet is attached with a non-slip sand grain layer, and the back side of the base cloth sheet is bonded and fixed to the corresponding surface of the insulation board body by an adhesive.

The anti-slip sheet is emery cloth.

The anti-slip sheets are parallel distributed on the surface of the insulation board body in the shape of straight strips or straight strips.

The anti-slip sheets are circular or polygonal and scattered on the surface of the insulation board body.

The anti-slip sheets are distributed on the surface of the insulation board body in the form of wavy strips or wavy bands.

The anti-slip sheet is provided with cutting marks, nicks or indentations for removing part of the anti-slip sheet from the anti-slip sheet.

The insulation board body is extruded foam board, polyethylene insulation board or polyurethane insulation board.

The surface of the thermal insulation board body of the utility model is pasted with anti-slip sheets, which increases the roughness of the surface of the thermal insulation board without causing damage to the thermal insulation board itself and other structures of the embankment, thereby increasing the distance between the surface of the thermal insulation board and the waterproof layer. The friction between the surface of the embankment and the waterproof layer can be effectively prevented from falling off during the construction process, and the utility model also takes into account the friction between the surface of the thermal insulation board and the waterproof layer during the construction of laying the waterproof layer The resistance cannot be too large, because excessive frictional resistance will cause the waterproof layer to be difficult to drag and move when it is spread on the surface of the insulation board and it is inconvenient to adjust. On the surface of the board body, when the anti-slip sheet is too densely distributed on the surface of the insulation board, resulting in excessive frictional resistance to the waterproof layer and affecting the laying of the waterproof layer, the construction personnel can remove the excess by lifting the flexible base cloth as needed. The anti-slip sheet is removed from the insulation board body to reduce friction. Since the flexible base cloth sheet is bonded to the insulation board body by an adhesive, the operation of removing the anti-slip sheet is convenient and will not damage the insulation board.

Detailed ways

Embodiment 1 of the thermal insulation board of the present utility model is shown in Fig. 1 and Fig. 2, comprising a thermal insulation board body 1 made of extruded board foam board material, and a straight anti-slip sheet 2 is pasted on the surface of the thermal insulation board body 1 Each of the anti-slip sheets 2 includes a flexible base cloth sheet 21, the front of the base cloth sheet 21 is attached with a non-slip sand grain layer 22, and the back of the base cloth sheet 21 is bonded and fixed to the corresponding surface of the insulation board body 1 by an adhesive . The length extension direction of each straight strip-shaped anti-slip sheet 2 is consistent with the width extension direction of the insulation board body 1, and the anti-slip sheets 2 are distributed in parallel in two rows on the length extension direction of the insulation board body 1, and each row of anti-slip sheets 2 is in the row direction. Staggered distribution, double-row staggered distribution of each anti-slip sheet can be evenly distributed on both sides of the insulation board, and one end of the anti-slip sheet is close to the edge of the insulation board to facilitate removal. During construction, the construction personnel can remove the redundant anti-slip sheet 2 according to the frictional resistance requirements on the site to reduce the frictional resistance. Since the flexible base cloth sheet is used, the insulation body 1 only needs to be removed when the base cloth sheet 21 is lifted. The opening is partially stressed, so the operation is labor-saving and convenient without damaging the insulation board.
