DE19547395A1 - Room wall dowelling for long life heat storage - Google Patents

Abstract

The free spaces (1) run parallel to the room walls etc but at right angles to the heat flow, and the individual boards are arranged with minimum overlap (2), using wooden dowels glued in as board connection (3). Horizontally milled grooves can act as installation ducts and the boards are so joined as to give a straight outside surface. Dissimilarly wide boards can reduce storey floor deflection due to the lower inherent weight of the boards, and the first row of boards should be pointed at their ends so as to fit easily into the boards in the adjoining wall element, the boards in turn each bevelled at their outer edges to coil in a circle once installed.

Description

The dowel binders are to be used 1. in the house and object construction as exterior and Interior walls, floors, ceilings and roofs and 2. for use in insulated container construction for long-term heat storage.

In house construction, materials such as stones, wood, fibreboard, insulation are usually used panels and insulation materials to achieve good thermal insulation in several Layers used.

The different physical properties of these materials can, however Cause problems. The materials with good thermal insulation values usually have a ge rings static strength. The materials with high strength such as steel, stones and Concrete has a high thermal conductivity.

Dowel trusses consist of solid wooden boards which include cavities in egg a special procedure.

Dried and planed boards are cut according to a certain pattern with holes hen provided, glued to each other, dowelled and then pressed under high pressure. This results in dimensionally stable components.

One side of the elements consists of grooves and the other of tongues. The feathers are chamfered. The insides of the elements are horizontal Grooves.

The elements have been developed for house and contract construction as well as insulating container construction been. There are special types of elements for exterior walls, load-bearing interior walls, not load-bearing interior walls, ceilings and roofs planned.

Within these product groups there are special elements that make up the raw simplify construction considerably. These are inside corners, outside corners, wall closing elements, compensation elements, lintels, parapets, vertical and horizontal Interconnects. As a manufacturer of these dowel binders, sawmills and glue binder manufacturers thought. Marketing is to take place via the timber and building materials trade.

The material wood in connection with many air-filled cavities results in a be particularly favorable heat transfer coefficient (K value).

The requirements placed on a low-energy house can be met. The dowel binders uniquely combine the properties of the optimal ones Thermal insulation with excellent static strength.

The wall structure consists of a homogeneous material with all of the resulting the benefits.  

The dowel binders ensure the arrangement and connection of the individual boards excellent thermal insulation and heat storage with first class at the same time static properties. In particular, these are high strength, good fire resistance stood, good sound insulation, good load capacity with low weight, high dimensional accuracy ity, spatial stability, water absorption, stability, pleasant indoor climate.

Special production lines are under development for production. The assembly on the construction sites can be done by specialist companies (carpentry) or by the building owners themselves respectively.
