Description

Heat-insulating inserts eliminating thermal bridges in walls made of blocks
The subject of the invention is the group of heat-insulating inserts eliminating thermal bridges in walls made of blocks. The invention is particularly useful when building external walls of silicate blocks or cellular concrete blocks with the use of adhesive. As the blocks have technological holes or grooves for holding or carrying, it may cause problems.
Considering the recent development of construction technology, perpendicular blocks made of variuos materials such as cellular concrete, expanded clay aggregate, silicate, gypsum, etc. are popular materials for constructing external walls. Currently, the blocks possessing grooves designed for holding or carrying them, are more and more popular. Additionally, some of them, especially silicate blocks come with the technological holes all along their height. The walls are built the way that only the jointing parts of the blocks are filled with sand and cement mortar or adhesive. The blocks are aligned with one another the way that the spaces between their side walls are not filled with the mortar or adhesive. In cosequence, said technological holes and grooves create air spaces inside the wall. After rendering such a wall, its subsequent movement results in appearance of micro-cracks on it, causing intensified air circulation through the cracks to the air spaces between side walls of the blocks inside the wall. Such a process leads to the deterioration in heat-insulation properties of the wall. The disadvantage of the described block wall technology is the occurence of dew points. The issue becomes even more important when the wall is a singlelayer block wall made of the blocks enough thick to provide desired heat- insulation level, namely the wall without a heat-insulating layer (e.g. expanded polystyrene). Apart from that, the technology in question requires the use of excess amount of jointing material as some of it gets into the holes and grooves of the blocks.
The patent No. CN2568726Y proposes the solution in the form of inserts made of heat-insulating material that are designed for pushing them into the empty spaces in blocks as well as into the gaps between blocks. The disadvantage of this solution is the inability to obtain full heat-insulation of the gaps between the blocks within the wall. Other patent description (No. PL226253) presents a set of inserts eliminating thermal bridges in walls made of blocks. It is made of heat-insulating material (usually expanded polystyrene) and includes three elements: big insert, small insert, and distancing plate. The big insert has parallel top and bottom surfaces and side walls matching the shape of grooves, that are designed for holding blocks, in two neighbouring blocks - in their part of bigger volume. The small insert has parallel top and bottom surfaces and side walls matching the shape of grooves, that are designed for holding blocks, in two neighbouring blocks - in their part of smaller volume. The distancing plate has the same dimensions as the block side wall and has the groove of the shape corresponding to the cross-section of joined small and big inserts. The width of inserts is extended by the width of distancing plate.
The disadvantage of the latter solusion is the excess in amount of work necessary to fit the inserts in correct places when building a wall, but also high fragility of expanded polystyrene inserts. The aim of the invention in question is to design the construction of heat- insulating inserts that lack of the faults described above.
The inserts eliminating thermal bridges in walls made of blocks proposed in this invention have the form of bundle of pipes (permanently joined together by a cylindrical strips) of a cross-section in the shape of a circle or any polygon, providing that the diameter of the cross-section of each circular bundle, or the maximum size of the cross-section of the polygonal bundle stays within the range 2-7 mm and they are made of flexible and resilient material, prefe rably of thermoplastic polymer, ultimately of polyethylen, with the shape of cross- section close to the cross-section of the hole in the block or cross-section of the hole created by the joined blocks, in the manner that the dimensions of the cross-section of the bundle stays within the range of 97-120% of the corresponding hole and/or is deformable with the use of hands to the shape and dimensions of the hole in the block. The height of the insert should not exceed the height of the block.lt is preferrable that the bundle is composed of pipes. Optionally in production and preferably, the bundle is composed of pipes positioned along the circumference with a hollow space in the middle of the bundle.
The subject of the invention is reviewed in detail on the examples in the figures, where Fig.l presents an axonometric drawing of inserts made of circular pipes designed for use as insulation in walls built of silicate blocks; Fig.2 presents an axonometric drawing of the joint of two silicate blocks with inserts; Fig.3 an axonometric drawing of inserts the full one and the one with a hollow space in the middle, both designed to fit te gaps created by two joined cellular blocks; Fig. 4 an axonometric drawing of two joined blocks with partially immersed inserrts.
Example 1 Heat-insulating inserts 1. 1’ for fitting two circular technological holes of various diameters in silicate blocks 2 They consist of: The first insert made of cicrular pipes 3 , of 3 mm diameter, providing the diameter of the shape of the insert 1 cross-section is equal to the diameter of the smaller hole; The second insert V has the form of the bundle of hexagonal pipes 3’ of 5 mm diameter and the insert diameter is equal to 110% of the bigger technological hole. The insert 1” has the cross-section in the shape of right trapesoid and consists of pipes 3 of 7mm diameter and it fits the hole between joined blocks, on the side of the groove that is designed to carry the block 2. The dimensions of the cross-section of the insert 1” are equal to 98% of corresponding dimensions of the hole in the joint between the blocks 2; The height of all inserts 1, 1’,1” is equal to the height of the blocks 2.
Example 2 The insert 4 is designed to fit the hole created by two grooves of different sizes shapes between joined blocks 5 made of cellular concrete. It has the form of the bundle of circular pipes 3 of 7 mm diameter each, providing the shape of the cross-section of the bundle (insert) 4 has the shape of the surface created by the sections of two elliptical crescents joined together and pipes 3 are situated in four rows on the circumference of the bundle, with a hollow space in the middle 6 The height of the insert is equal to the depth of the grooves in the blocks 5.
Example 3 The insert 4’ is designed to fit the hole created by two grooves of the same size by two identical blocks 5 made of cellular concrete. It has the form of the bundle of circular pipes 3 of 6 mm diameter each corresponding to the shape of the hole in joined blocks 5, (in the cross-section it is created by the sections of two elliptical crescents joined together), and each dimenion of the of the cross-section of the bundle is equal to 100% of the corresponding hole between joined blocks 5. The height of the insert is equal to the depth of the grooves in the blocks 5.
