This application claims the benefit of German Patent Application No. 10 2021 003 243.8, filed 2021 Jun. 24, the contents of which is incorporated by reference in its entirety.
The disclosure relates to a chamber for curing building materials. The chamber comprises sheet metal elements which are built on a base plate, insulated from one another, and form walls and a ceiling.
Curing chambers are generally known for drying bricks. Chambers for curing concrete blocks have rack systems made up of several rack supports and several support elements arranged on the rack supports for supporting shelves on which the concrete masses to be hardened are stored. Air, adjusted in its temperature and humidity, is fed through duct systems to the concrete masses to be cured. In some cases, the supply air duct system can be integrated into the rack system. Another complex exhaust air duct system, which can also be partially integrated into the rack system, serves to ensure a corresponding flow.
The disclosure provides a cost-effective curing chamber suitable both for concrete blocks and for building materials cured by CO2.
In a chamber of this type, the walls and/or ceiling consist of self-supporting, double-walled sheet metal elements connected to one another in an essentially gas-tight manner. The double-walled sheet metal elements supply and/or discharge and distribute a gaseous curing medium from outside the chamber in its interior.
The self-supporting sheet metal elements eliminate the need for complex rack systems. Due to the double-walled sheet metal elements, the gas supply and the gas discharge is considerably simplified and made more economical.
Advantageously, air with defined, predeterminable temperature and humidity conditions can be used in the chamber air as the gaseous curing medium for curing of concrete. Alternatively, CO2 can be used as the gaseous hardening medium for curing building materials.
The walls and/or ceiling are formed self-supporting from several trough-shaped sheet metal elements. Those consist of a base area, side walls bent on all sides and edge strips bent inwards opposite these and running essentially parallel to the base area. Metal panels are arranged in the so formed interior area of the double walls and/or double ceilings of the chamber in a substantially gas-tight manner on the edge strips. Edge joints are firmly and substantially gas-tightly connected to one another. The sheet metal elements with their base area standing in a common plane are held together by their side walls via connections bracing seals. Sheet metal elements that adjoin at right angles are held by side walls bracing connections via seals with edge strips and sheet metal panels arranged thereon. The double walls and/or double ceilings have a media inlet and/or media outlet. The metal panels are assigned support elements for bracing supports for the building materials. The metal panels have media inlets and/or media outlets directed into the chamber.
To ensure tightness and stability, it has proven useful for the connections between the joints of the side walls and the edge strips of the trough-shaped sheet metal elements to be formed by a weld seam.
It is expedient for self-adhesive sealing strips and/or pasty sealants to be used circumferentially and/or continuously as seals. If, for example, silicone is used as a pasty sealant, subsequent insulation is possible without having to pay attention to whether the sealing strips might be damaged when assembling the chamber.
So that the ceiling can be walked on without any problems, it is expedient for trough-shaped sheet metal elements and/or sheet metal panels intended for ceilings to be made of sheet metal of greater thickness and/or a material of greater strength than the trough-shaped sheet metal elements and/or sheet metal panels intended for walls and/or have wider side walls and/or edge strips.
For the thermal insulation of the outer walls of the chamber, it is proposed that walls formed by base surfaces of trough-shaped sheet metal elements are assigned claddings provided at distances of the thickness of insulating packings, with the cladding being made of trapezoidal sheet metal.
For the thermal insulation of the ceiling, it has proven useful for the ceiling formed by bases of trough-shaped sheet metal elements to be assigned claddings at distances of the thickness of horizontal insulating layers, with perforated metal sheets being able to be provided as cladding.
To thermally insulate the sheet metal elements from one another, it is advantageous for the spaces between the bases of opposing trough-shaped sheet metal elements or the spaces formed between by the bases of the trough-shaped sheet metal elements and the cladding to be filled with pourable insulating material and/or insulating plates.
The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
Each double-walled sheet metal element 4 consists of a trough-shaped sheet metal element 8 with side walls bent on all sides and opposite these inwardly bent edge strips 9 running essentially parallel to the base surface of the trough-shaped sheet metal element 8. The joints of the side walls and edge strips 9 of the trough-shaped sheet metal elements 8 are connected with each other gas-tight by a welded seam. This weld also increases the stability of each individual trough-shaped sheet metal element 8.
Support elements 10 are screwed, welded or hung onto the edge strips 9. The support elements 10 are used to support carriers, not shown, for the building materials. The edge strips 9 are designed so large that between the docking points for the support elements 10 on one side of each trough-shaped sheet metal element 8 and the docking points for the support elements 10 on the opposite side of each trough-shaped sheet metal element 8 sheet metal panels 11 are screwed on in a substantially gas-tight manner. The sheet metal panels 11, which lie behind the support elements, have openings, holes or nozzles through which the building materials can be blasted with gas in a targeted manner or through which the gas is sucked back into the double-walled sheet metal panels, depending on whether the double-walled sheet metal elements 4 are connected to a media inlet 6 or a media outlet 7.
The chamber 1 has a plurality of doors 12, through which the contents for the chamber 1 can be introduced. On the ceiling 3 double-walled sheet metal elements 13 are also provided. The chamber has a railing 14 on the ceiling 3 for fall protection.
At the upper end of the walls 2, the double-walled sheet metal elements are provided with media inlets 6 and media outlets 7, respectively. There is the possibility that not every double-walled sheet metal element 4 of a wall 2 is equipped with a connection for the gas, but that for example only every second double-walled sheet metal element 4 is supplied with corresponding gases or that gases are drawn off only through every second double-walled sheet metal element 4. In this case, an offset of a double-walled sheet metal element 4 can be provided between the media inlet 6 on the one side and the media outlet 7 on the other side so that the gases flow obliquely through the chamber 1 from a media inlet 6 to the offset media outlet 7.
The words “example” and “exemplary” as used herein mean serving as an instance or illustration. Any embodiment or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word example or exemplary is intended to present concepts in a concrete fashion. As used in this application, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or”. That is, unless specified otherwise or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.
While the present invention has been described with reference to exemplary embodiments, it will be readily apparent to those skilled in the art that the invention is not limited to the disclosed or illustrated embodiments but, on the contrary, is intended to cover numerous other modifications, substitutions, variations and broad equivalent arrangements that are included within the spirit and scope of the following claims.
