Do I need to hire internal vibrator for concrete, or more profitable to buy?

deep vibrator During pouring the concrete into the formwork solution must ensure uniform pressure distribution in the mixture.Previously, for this simple steel pins used in which by mixing excess air was removed from the solution.But large amounts of construction, this method is extremely time-consuming and unproductive.Therefore it is recommended to use a special device - vibrator.But the question arises, take it to rent or purchase a new one?

In some cases a vibrator

First of all, you must ensure the appropriateness of the use of this device.When enough liquid solution all its weight under gravity alone to fill the entire interior of the formwork.But if the composition is characterized by high density and high content of gravel (typical for the foundation) - that without concrete vibrator to ensure quality design is virtually impossible.




Vibrate

addition vibrators conditions recommended in the following cases:

  • Building columns or similar structures.
  • A high volume of formwork.
  • If the design has internal partitions that prevent the free distribution of the solution.

in private construction vibrators are used mainly for the construction of the foundation.Since in this case, the composition features a large number of solution hardening components, the density of the mixture is relatively high.To take a decision on the need to use vibrators to help professional builders.

rent Urgency

Before purchasing or renting vibrators must weigh the "pros" and "cons."The main condition for this is economic feasibility.If the device is to be used only during the construction of the 1st object - it is best to take it out.At a higher volume should calculate the purchase price and compare it with the rent for the entire period of the possible use.Another alternative to buying the device is to purchase a special nozzle on the drill.

However, in this case, the device performance will be determined by power drills.When using concrete grade M-150 or M-200 composition density can be so high that the device simply would not work in this environment.

For a full analysis should compare the cost of renting, buying a new vibrators and special nozzle on the drill.For this we take the average price indicators on the construction market.

  1. rent.Its cost depends on the duration of use.If the device is needed only during the 1st day, the price of this service will be at least 500 rubles.For a period of one month rent cost about 1000 rubles.
  2. Buying the simplest models can cost from 3 500 rubles.
  3. Special nozzle for drill will cost 1600 rubles.

According to these rates, the rent of the vibrator, even in the construction of private country houses will be more than justified.But this decision is necessary to carefully analyze all the factors - the amount of work, the degree of difficulty of their performance and duration.
