いる。 With the development of various materials and the strong demand for insulation and waterproof functions, the base materials used for various parts of buildings have changed from simply laying conventional roofing boards or small boards, to plywood plywood, and plasterboard. , asbestos slate, etc. alone, to so-called composite base boards that combine materials made of various materials with insulation and waterproof functions and base board base materials with the required strength such as veneer plywood. have been improved and developed one after another and are now widely put into practical use.

た。 However, in the case of these conventional composite base plates, especially composite base plates combined with waterproof materials such as asphalt-impregnated sheets, the waterproof material and the base plate base material are bonded together over the entire contact surface of both. For example, if a metal plate is applied directly to the surface of the waterproof material to create an exterior finish, the surface of the waterproof material will respond to temperature changes from the outside. This causes extreme expansion and contraction, while the back side is fixed to the base plate, which causes distortion between the two, which in turn causes damage to the waterproof material itself. The material deteriorated and cracked, making it difficult to maintain its function as a waterproof material for a long time.

下地板が形成される。 This invention was developed and devised in order to eliminate the drawbacks of these conventional composite base plates, and as can be understood from the illustrated representative example, the structure consists of a base plate having the required strength. For example, synthetic resin foam (including those mixed with inorganic material powder) or mineral fiber molded body,
The heat insulating material 2, which is made of a material such as a vegetable fiber molded body and has a relatively bulky property, is laminated and integrated,
A waterproofing material 3 made of a sheet impregnated with asphalt, a sheet impregnated with a bituminous material such as tar felt, or a combination of a sheet impregnated with a bituminous material and a synthetic resin sheet, aluminum foil, etc. is laminated on the surface. As can be understood from the sectional view in FIG. 1, the laminated structure of the waterproof material 3 on the base plate base material 1 is such that the waterproof material 3 is stacked on at least one set of opposing sides of the base plate base material 1. Inside, one side has a protruding shape, and the other side has a predetermined width l
The composite base plate of this invention is formed by forming a laminated structure in which the two are not bonded and the two are partially bonded, for example, the adhesive 4 is bonded in spots or in rows.
なお、この部分接着の程度は防水材３の材質な
いしは材厚に応じて最適な接着面積が決定されな
ければならないことは勿論のこと、接着状態にお
いても斑点状とするか列条とするか、もしくは格
子状等とするかはその都度最適なものが選択され
なければならない。 As for the extent of this partial adhesion, it goes without saying that the optimal adhesion area must be determined depending on the material or thickness of the waterproofing material 3, and also whether the adhesion should be done in spots or in rows. Or, whether to use a lattice shape, etc., the most suitable one must be selected each time.
また、下地板基材１の側端から所要巾１の範囲
には全く接着剤を使用しないで未貼着状態とし、
その余の部分を部分接着するようにした構造とす

在の防水材接合構造を実現するものである。 In addition, no adhesive is used in the area of the required width 1 from the side edge of the base plate base material 1, and the area is left unattached.
By having a structure in which the remaining parts are partially glued, the protruding waterproof material 3 of the adjacent composite base plate is inserted and polymerized into the end-attached part of the side, and the waterproof material is waterproof against mutual expansion and contraction deformation of the adjacent base plates. This is to realize a waterproof material joint structure that can be expanded and contracted to prevent deterioration due to stress placed on the parts where the materials are joined.
一方、断熱材２には図示した実施例には示され
ていないが表裏に貫通する細孔５を多数穿設した
ものとし、下地板基材１の変形を防止するような
構造のものとしても勿論差し支えない。 On the other hand, although not shown in the illustrated embodiment, the heat insulating material 2 is provided with a large number of pores 5 penetrating through the front and back surfaces, and may have a structure that prevents deformation of the base plate base material 1. Of course you can.

つた歪みによる防水材の早期劣化現象を能く防止
するものとなつている。 As mentioned above, in the composite base plate of this invention, the waterproof material is combined and laminated in a specific relationship to the base plate base material, so that the waterproof material joints between adjacent composite base plates and other The adhesive part at the end allows the waterproofing material to expand and contract freely due to temperature changes, preventing undue distortion of the waterproofing material itself, and thus eliminating distortion, which was the biggest drawback of previous models. This effectively prevents the early deterioration of waterproof materials.

水層を形成することができるものである。 In particular, among at least two opposing sides of the waterproof material, one side is protruding and the other side is unattached with a predetermined width, and one side of the protruding side is laminated from the surface of the underlying base material. By setting the height to be lower than that of the other unbonded side, and simply inserting and polymerizing one protruding side under the other unbonded side, a waterproof material joining structure can be realized. It forms a waterproof layer that is unaffected by the mutual expansion and contraction of the base plate base materials, and is characterized by the fact that each unit area formed as a prefabricated member is made up of adjacent waterproofing materials that are independent and continuous. In addition, even if condensation occurs between the surface of the temporary waterproofing material and the roofing material and water droplets are formed, the waterdrops will first spread to the bottom surface of the other unbonded side of the waterproofing material joint. Unless it enters between the upper surface of one side of the protruding shape and reaches the tip of one side, and then goes between the lower surface of one side of the protruding shape and the upper surface of the base plate base material, the adjacent lower Therefore, for example, the
As in the inventions described in Publication No. 37698 or Japanese Patent Application Laid-open No. 38323/1983, once condensation occurs, it easily reaches between the abutting parts of the base plate and causes water leakage. It also has the characteristic that it can almost completely eliminate the disadvantages that occur when
At the base plate joint of this invention, it is possible to form a perfect waterproof layer with almost no deterioration or water leakage.
更にまた、裏面には断熱材２も一体に積層さ

ある。 Furthermore, the heat insulating material 2 is also laminated on the back side, and has both waterproof and heat insulating functions, making it particularly easy to handle and manufacturing. It can be said to be a practical base plate that has many features such as being as simple and simple as a regular base plate.
