Exhibition Room Design

Designing room for certain exhibitions are depends on the kind of exhibition that will be showed. Exhibition for computer are very different compare with car exhibition, because computer don’t need large space, and for car exhibition need large room space.

Room arrangement also will very different between both exhibitions, for product that don’t need large space is just need narrow partitions but for big product need wide partition and wide room space like for car exhibition.

For car exhibition need wide room and just need a tie border to give more special service and can give much information and make feel comfort for every visitor. For this purpose we can design in maximize room design.


For computer show better build a walk path, and just one way direction because if the visitor too much will difficult to walk if not be designed in one way direction, for every space can design in minimalist model like on the photo below.

Build a Concrete

Build a concrete should intense to the final quality of concrete, the final of concrete result must be strong and sometime should not leakage from seep water, especially when the concrete also used as open roof of our house.

For those purpose some preparation before conduct a concrete molding must be done, such as preparation and cleaning. When applying any coating to concrete or steel, and even when bonding new concrete to existing, adequate surface preparation of the substance is fundamental to success. For coating product that possess excellent adhesive properties and have a high tolerance level, thorough surface preparation and cleaning are absolutely essential.

The ideal surface for a coating material system should be:
There are many methods of surface preparation an cleaning, including a number of proprietary systems. In principle, the most effective methods are mechanical, such as Blastrac vacuum blasting or Von ARX planning machines. Open blast cleaners, scabblers, grinders, power brushes and needle guns are suitable for use on many projects, or in confined areas and edges where not accessible by larger equipment.

With all methods of surface preparation it is important to carry out the mechanical or cleaning operations to the required standards, and to check that this is done. During maintenance and refurbishment work, it may be necessary to remove contaminants from the surface, or even from within the upper layer itself. It may, therefore, be necessary to use chemical cleaners, detergents, emulsifiers, steam cleaning, high pressure water jetting, or a combination of these to clean the substrate. This is normally best carried out prior to mechanical preparation. In cases of severe contamination this cleaning may need to be repeated after mechanical.

House Model

This section describes how one uses equivalent wall results to a house model in transient building simulation programs. For the purposes of this example, a simple house design of typical construction is used as a reference, as shown below.



Successful implementation of the equivalent wall approach largely depends on the proper dimensioning of building envelope components. A wall elevation for the house shown above is depicted in below. The wall system is comprised of 2 x 4 steel stud with R-11 insulation, and contains one door and one window. Only one wall is shown here, since it is assumed that the procedure that follows can be applied to construct the remaining walls of the house.

The first step is to list the building envelope sections that exhibit transient and multidimensional effects. The sample wall elevation contains the following sections of dissimilar thermal response: wall/floor, wall/ceiling, corner wall interfaces, window header, window framing, door header and door framing. In this example, the thermal response of the door header and window header are assumed equal. Figure below distinguishes each of these zones by color, with the dimensions of the transient and three-dimensional effects as indicated in the Wall Assembly Information Sheets.

The second step is to determine the building envelope areas for each dissimilar section. As noted previously, it is important not to double-count building envelope areas. The easiest way to avoid this problem is to first calculate the areas of the building envelope that contain three-dimensional effects. These values can then be subtracted from the total building envelope area to determine the clear wall area.
