TYPES OF SCAFFOLDING

Thursday, November 2, 2023 By Jessica Hernández Sales Assistant  

Scaffolds are structures that are used in construction sites as a tool to reach certain heights or areas of difficult access to perform the necessary work. In addition to fulfilling this function, scaffolding must be correctly assembled to ensure the protection of the person carrying out the work, otherwise, this may cause falls of people or materials, as well as collapses. They are platforms with stable surfaces and are available in different materials and sizes.

Trestle scaffolding

It is the simplest scaffolding that exists, characterized by being A-shaped. It is used in constructions that do not exceed 4 meters in height due to the simplicity of its structure. It is used as an auxiliary for simple tasks such as painting tiny houses.

Cross brace scaffolding

This is the standard scaffolding, also known as scissor scaffolding, it is very easy to transport and low cost. It is not approved for outdoor use, so it is more commonly used indoors.

European scaffolding

It is the type of approved scaffolding, besides being modern, it complies with all current European safety standards. It has non-slip platforms, trapdoor and ladder to facilitate access to each of the different levels or heights of the scaffolding. Its stability is ensured by assembled diagonal and horizontal bars.

Suspended scaffolding

These are mobile structures suspended from the ceiling, roof, or beam. They are ideally used to perform work from 20 meters in height and allow the user to change levels. It is commonly seen in window cleaning jobs in large buildings.

Multidirectional scaffolding

They are resistant and versatile. Their main characteristic is that they are capable of forming frames that adapt to any position and shape, even curved. They allow work levels to be varied every 0.50 meters while maintaining all safety elements. Their use ranges from simple projects to the most complex and industrial uses.

Mobile scaffolding

They are very stable and efficient for working in smooth and flat environments. They are composed of simple, manageable, and light pieces that facilitate their assembly, disassembly, and displacement.

Self-erecting platform scaffolding

Systems whose platform operates electrically on 1 or 2 masts. It has a control panel and an overload locking system.

 

It is important to choose the type of scaffolding according to the task to be performed, this will result in faster and more efficient work. Also, you will protect the lives of the workers and those who pass around the work site. At SILMÉXICO we advise you about the ideal type of scaffolding for your new development.

CONSTRUCTION MACHINERY

Monday, Wednesday, October 25, 2023 By Jessica Hernández Sales Assistant at SILMÉXICO  

In the construction industry, different equipment is used during the beginning, in the middle, and at the end of the work to facilitate the work. Having the right tools and machinery will ensure the efficiency of the processes in the different stages of construction, in addition to preventing the physical integrity of the workers from being put at risk. Whether you are looking for machinery to buy or rent for your project, you should know their types and functions, and based on that choose the ones that fit your needs. In the following blog, we share with you about construction machinery and its types.

The size and characteristics of the machines vary according to the activity you are looking for them to perform, among which we find:

    • Excavation of land in which the settlement of the foundations of various structures will be made.
    • Soil displacement to shape the land on which roads or highways will be set.
    • Loading and unloading of construction material.
    • Mining activities.
    • Separating some part of the soil layer with the objective of transforming the terrain according to the project to be executed.
    • Now, machinery owes its classification to its different sizes, which is why it is divided into heavy, semi-heavy, and light.

Heavy Machinery

As their name indicates, these are of a great size and weight, all of them must be operated by a person with high knowledge in their handling, and following the corresponding security norms. In this category we can find:

Bulldozer

It has a powerful front shovel and is mounted on rails or tracks. This machinery is mainly used for heavy-duty work such as excavation, land leveling, soil piling, etc.

Excavator

This is the most important heavy machinery used in the construction industry. Their main use is excavation; however, they can also be used for other purposes, such as demolition, river dredging, etc.

Mini excavator

It is a small industrial equipment. It is their size that makes them practical and useful for a variety of jobs. It helps to prepare the ground, excavate, and remove debris in hard-to-reach places. Even on uneven terrain. The mini excavator is a versatile machine that is also used on farms, in confined environments; but it is especially useful in civil construction because of its compact size and ease of transport.

Backhoe

It has a bucket at the front and a digging arm at the rear, which allows them to perform a variety of tasks.

Examples include excavation, demolition, material moving, asphalt removal, and road paving, among others.

Motor graders

It is a self-propelled construction machine with wheels. It incorporates an adjustable blade located between the front and rear axles to cut, move or flatten the ground.

Skid steer loader

Also known as a skid-steer loader, it is an extremely compact type of tractor. It has a loader arm attached to its front end.

Also, unlike most of the above machines, the skid steer loader is light, small and very agile.

Articulated trucks

These are motor vehicles consisting of two or more interdependent structures connected by a hydraulically assisted axle. This allows the truck to maintain its connection between the tractor and the trailer. The articulated truck is mainly used to transport construction materials such as sand, cement blocks, rubble, etc., in quantities that exceed the capacities of a traditional truck and in terrain where other vehicles would get stuck.

Semi-heavy machinery

Unlike the previous ones, these have a smaller dimension, they are used to remove a smaller amount of soil compared to heavy machines. In turn, they can be used to excavate land that is not too deep or to load medium-weight elements.

They include the following:

    • Construction dumpers
    • Small excavators
    • Small cranes

Light machinery

These are of much smaller size and are used to perform tasks that do not require so much demand, are subdivided into pneumatic that operate on the basis of compressed air and electricity, some examples are:

    • Water pumps
    • Compressors
    • Vibrating machines
    • Steel cutters

STUDY OF SOIL MECHANICS

Friday, September 29, 2023, By Jessica Hernández, Real estate advisor and marketing analyst in SILMÉXICO

In a previous post, we talked about soil classification and how important it is to identify them when planning a construction project. To do this, it is necessary to carry out a soil analysis, which will be discussed below. 

Soil analyses allow us to know the chemical, physical, and mechanical characteristics of the land where the work will be carried out, the layers or strata that make up the soil as well as its depth.

The study of soils or soil mechanics is made up of 3 stages:

1. Exploration and land testing

In this first stage, a reconnaissance of the site is carried out, strategic points are explored and soil samples are taken, which will be analyzed later in a second stage in the laboratory. These samples are taken through various techniques and tools such as:

    • Calicata: to make excavations of small or medium depth in chosen points of the ground. This seeks to have a direct view of the terrain that is generally not seen, for its characterization and analysis.
    • Penetrometer: consists of the penetration of the soil with the introduction of this tool into the ground, which generally has a conical shape.

Probes: Through these, the ground is drilled with a cylindrical probe that extracts the soil trapped inside the cylinder. As the samples are taken, they are placed in order of depth in boxes, to determine the type of soil at different depths.

2. Laboratory work

In this second stage, all the samples taken in stage 1 are taken to the laboratory for analysis. Laboratory tests will allow us to know issues such as humidity level, consistency limits, pressures, and sky components, among others.

3. Preparation of final report

The last stage consists of writing the final report of the study carried out, in which all the observations, results of the samples, and the characteristics of the land are detailed, whether it is suitable or not to carry out the construction project, it is delimited the amount of weight the soil can support, and recommendations on materials and construction are also issued.

 

Have you ever wondered why the Tower of Pisa is tilted? This was not precisely the design or the intention for this historical and tourist monument, the reason for its inclination is that at the beginning, the work was vertical, but over time it was inclined because it is located on unstable ground and does not have foundations to support the weight of its 56 meters high. That is why the study of soil mechanics is important, it allows the land to be prepared according to the structure that is intended to be built, which will determine whether or not it can deal with the passage of years, possible telluric movements, etc. Correctly carrying out this study can save lives, as well as preserve large and important buildings.
