DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the use of two types of panels, an upper layer panel (1) and a lower layer panel (2), to fill a fresh concrete at a construction site, Work such as temporary installation of circulation pipes and reinforcing materials can be omitted, and construction can be performed without being affected by climate or weather, etc.
And when the upper layer panel is damaged, only it can be replaced,
In addition, the present invention relates to a heat medium circulating road heating construction method that can easily repair the heat medium circulating pipe (2c).

[0002]

2. Description of the Related Art Conventionally, a heat medium circulation type road heating construction method for snow melting is carried out by bringing construction materials to a construction site, filling and hardening of ready-mixed concrete, a heat medium circulation pipe, a reinforcing material, a heat insulating material. All of the construction methods, such as burial, were performed at the construction site. Further, as in the present invention, the panel is divided into an upper layer and a lower layer, and is produced in advance at a construction site, and can be assembled or inserted and removed at the construction site and weather,
Nothing could be constructed without being affected by the climate. Further, there has been no mounting method of fixing metal fittings that integrates the upper layer panel, the lower layer panel, and the metal fittings for integrating the base part when the panels are juxtaposed, and does not interfere with the projections during transportation. . For this reason, the conventional construction method has a poor work efficiency, and it is difficult to work in low temperature periods and in rainy weather, and is not preferable in quality control. In addition, since the conventional heat medium circulation type road heating construction method is an integral molding, when repairing such as damage to the surface or deterioration of the function of the heat medium circulation pipe, it is necessary to demolish all and reconstruct it from the foundation. Expensive because there was no other way but to do it.

[0003]

The conventional heat medium circulation type road heating method has the following drawbacks. Work is complicated due to the method of performing the construction on site, there is a disadvantage that extra time and expense are required for the construction, and because the construction is extremely affected by the weather and climate, the construction can not be planned systematically Was. In addition, the construction took time.

[0004] In the conventional heat medium circulation type road heating construction method, it is difficult to replace the surface decorative layer, and repair and replacement costs are required.

In the conventional method of burying a heat medium circulating pipe in concrete, it is difficult to replace the circulating pipe, and a simple method has been desired.

[0006] In addition, because of the on-site construction, it is difficult to manage products and work, and the construction is not constant, making it difficult to produce a stable product.

[0007]

Means for solving the problems in the present invention is to manufacture a two-layer panel of an upper layer panel (1) and a lower layer panel (2) in advance, and insert and remove these two-layer panels. The present invention has devised a construction method which can be replaced and easily assembled by making it possible. Simple and excellent quality can be achieved by omitting the processes such as the temporary installation of reinforcing materials such as wire mesh or reinforcing bars, heat insulation material, pipes for heat medium circulation and the filling process of ready-mixed concrete, etc. Means have been devised that can form products.

[0008] Further, the present invention makes it possible to simplify the handling during transport and on-site construction by forming the upper and lower panels of the present invention. At the same time, repairs were facilitated.

The present invention is divided into an upper panel (1) and a lower layer panel (2) for the purpose of preventing the process from being affected by climate or weather during construction and preventing cracks or the like after construction. In other words, the product is to be produced as a well-cured product, and to perform road heating at the construction site using only the work of mainly arranging and overlapping panels. The upper-layer panel (1) and the lower-layer panel (2) to be used are made of individually produced concrete or resin concrete, and are reinforced, iron wire, wire mesh, or the like for the purpose of maintaining strength depending on the place of use. Alternatively, a fibrous material such as carbon fiber, aramid fiber, or glass fiber, and a mesh material thereof are simultaneously molded as a reinforcing material (5). In particular, as the resin used in the case of resin concrete, a reaction-curable synthetic resin such as an unsaturated polyester resin, an epoxy resin, or an acrylic resin is suitable, and the mixture with the aggregate (gravel, sand, etc.) is well reinforced. Use a resin with good adhesion to the material.

The upper panel (1) has a surface decorative layer (1).
a) and a concrete layer (1b) in which a reinforcing material is buried. The surface decorative layer (1a), which has been finished beforehand at a place other than the construction site, is a method in which tiles, bricks, rocking blocks, natural stones, etc. are pressure-bonded to the surface after hardening of the concrete panel, and a resin, aggregate, coloring agent, etc. Can be formed by applying and solidifying a mixture of the above to form a brick, a natural stone, a pattern, or the like, or applying a paint to the surface. Further, a fixing fitting (1d) for the purpose of alignment with the lower panel (2) is embedded and molded in the upper panel (1) at the same time. 1e) can be inserted into the concave fixing bracket (2f) of the lower layer panel. As a result, the upper panel (1) and the lower panel can be easily inserted and removed.

The lower panel (2) is an upper panel (1)

To form the concrete panel, first, the reinforcing material (5) is placed in a mold designed in consideration of the setting of the heat medium circulation pipe (2c) and the groove (2k) for filling the heat insulating material (2d). ), Heat insulating material (2e), fixing bracket (2f),
An anchor (2 g) is inserted and filled with ready-mixed concrete, resin concrete, or the like, solidified, cured, and integrated.
Next, a pipe is temporarily provided in the heat medium circulation pipe (2c) fixed groove (2k) of the molded product, and a foamable urethane resin is injected for the purpose of heat insulating effect and fixing, thereby forming the lower layer panel (2). To manufacture.

The reinforcing material (5) used here is generally an iron wire mesh or a reinforcing bar. As the heat insulating material (2e), a material having water resistance, alkali resistance, and heat resistance is suitable, but a polystyrene resin foam molded product is generally used. The heat medium circulation pipe (2
For c), those having corrosion resistance, cold resistance, flexibility, and excellent bending workability are suitable, and examples thereof include those made of synthetic resin such as polyethylene, polypropylene, and polyimide. Can be Further, the embedding and fixing of the heat medium circulating pipe (2c) are performed by using the groove (2
After setting to k), a foamable urethane resin is injected and foamed for the purpose of heat insulation and fixation, and the groove (2k) is filled.

The construction procedure according to the invention starts with the formation of the foundation (3). After laying gravel, sand, etc., the foundation is sufficiently hardened with a pressing machine so that the lower layer panel (2) can be set up on average. In particular, the surface layer of the base uses small-particle sand to facilitate anchoring.
At this time, the resin is further poured into the anchor insertion portion for the purpose of fixing the anchor, and the resin-impregnated portion (7) integrated with the anchor is cured and formed, thereby further stabilizing the portion.

[0014] Then, the lower layer panels (2) are arranged in a row in the plane direction on the base portion (3), and anchors (2g) protruding from the lower portion of the panel are cast into the base portion as required and fixed.
Next, the lower-layer panels are wedged with each other using the wedge-wearing bracket (4). Further, the heat medium circulating pipe (2c) is connected by a dedicated connection fitting (7d). Then, in order to prevent freezing and frost heaving in winter due to water entering from above, the abutting portion (2j) between the plurality of lower-layer panels juxtaposed on the horizontal plane is made of a soft material such as silicone rubber or soft epoxy resin. It seals with resin and completes the juxtaposition of the lower layer panel.

Next, an upper layer panel designed in advance for the lower panel is constructed. The upper layer panel (1) is manufactured in advance at a place other than the construction site in the same manner as the lower layer panel (2), but the upper layer panel and the lower layer panel need to be removed due to damage or the like in the future. The upper panel fixing insert (1e) is fixed to the recess of the lower panel fixing receiver (2f) without any adhesion or the like that makes it impossible to remove, so that the upper panel fixing fixture (2f) is easily detached. Upper layer panel (1) is lower layer panel (2)
When the upper panels are overlapped, a gap is formed in the upper panel abutting portion (1c) between the upper panels arranged side by side. As it is, snowmelt water, rainwater, washing water, etc. enter from this gap and may cause freezing and thawing, so prevent water from entering this gap, further consider aesthetics, and do not hinder removal work Durable materials such as urethane rubber, silicone resin, soft unsaturated polyester resin, soft epoxy resin alone or pigment,
The work to which the filler and the like have been added is injected and the operation is completed.

According to the present invention, the above-mentioned members are manufactured and prepared at a place other than the construction site, and only the panels are assembled at the construction site. This is a heat medium circulation type road heating construction method that is hardly influenced by natural conditions. Furthermore, the construction method can be performed during the winter period and is not affected by the weather, so that the construction cost can be greatly reduced and the quality can be controlled.
