Description

[Detailed explanation of the invention] Industrial application field Concrete slabs have poor resistance to chemicals such as hydrochloric acid and sulfuric acid, so a method of coating the surface with resin mortar made by hardening resin or sand with resin. is taken.

The present invention relates to such a coating device.

Prior Art and Problems When applying mortar to the top and side surfaces of the concrete slab, the current method is to apply mortar to the top and four sides one after another, making the coating work complicated.

Means for solving the problem The present invention was devised with the aim of solving the complexity of the conventional work process. , a protective material injection gap is provided between the spacer and the block body.

Embodiment In the drawings, FIGS. 1 to 3 show the first embodiment and the fourth embodiment.
The figures and FIG. 5 show a second embodiment.

The first embodiment has a pair of side pieces 2, 2 having a cutout 1 at the center of the upper edge, and a protrusion 3 at the center of the upper edge of the side piece 2 corresponding to the cutout 1. The provided middle pieces 4 are adhered to each other with the middle pieces 4 interposed, to form a spacer 6 in which a gap 5 formed by the cutout 1 is provided below the protrusion 3 of the middle piece 4, The spacer 6 and the concrete slab 7 are placed on a pair of horizontal parallel tables 8, 8, with the concrete slab 7 interposed between the spacers 6, and a first piece 9 having the same shape as the middle piece 4, An external piece 11 in which a second piece 10 of the same shape as the side piece 2 is attached to each other is placed at both ends of the concrete slab 7 and the spacer 6 in the juxtaposed direction with the second piece 10 inside, and parallel stands 8,8 This device was obtained by placing the outer piece 11 on top and pressing it from the outside as shown by the arrow a in FIG. After hardening, the mold is demolded to obtain a product having a surface protection material 12 made of resin mortar.

The second embodiment includes a spacer 26 in which a side piece 22 is attached to the lower center of both sides of the middle piece 24 and a gap 25 is provided above the side piece 22, and a first part having the same shape as the middle piece 24. A lateral outer piece 31 configured by attaching a second piece 30 having the same shape as the piece 29 and the side piece 22 to each other.
The second piece 40 is attached to each other so that a gap 32 is formed between the end 26' of the spacer 26 and the end 31' of the lateral outer piece 31 at the bottom of one side of the first piece 39. 3 members 2 of the longitudinal outer piece 33
6, 31 and 33 are combined together and placed on a pair of horizontal parallel tables 38, 38 with a concrete slab 37 interposed between these members 26, 31 and 33, as shown by arrow a in FIG. This device was obtained by pressing from four directions to maintain the juxtaposed state, and as in the first embodiment, resin mortar was injected and coated, and after hardening, the mold was removed to create a product with a surface protection material made of resin mortar. This is what we get.

Note that the spacers 6, 26, outer piece 11, horizontal outer piece 31, and vertical outer piece 33 are constructed by applying a paraffin-based mold release agent to the surface of a steel plate, but these materials are made of plastic or wood. But it's fine, and it doesn't have to be paraffin-based.

Resin mortar is made by mixing an unsaturated polyester resin (epoxy resin, furan resin, or vinyl monomer) with a suitable curing agent, and adding powdered heavy calcium carbonate (fine silica, silica powder, fly ash, We used a mixture of filler such as pozzolan (possibly pozzolan) and river sand (silica sand, crushed stone such as andesite) as aggregate, but the material mixture may be resin alone or resin concrete. .

In the embodiment, a so-called formwork is constituted by the spacers 6, 26, etc., but the structure of the formwork does not matter as long as the spaces 2, 25 can be secured.
The shape of the concrete slab is free when implementing the present invention, and it does not have to be a concrete slab. Therefore, the pressing means (in the example, a bolt) shown by the arrow a in the embodiment is not necessarily required, and the method of the pressing means does not matter.

Effects of the invention Since the present invention has the above-mentioned configuration, it is possible to coat a large number of blocks with the surface protection material at the same time, thereby increasing the workability of coating and resulting in an inexpensive product. It is possible to provide
