If you are still connected, then the resistance is calculated is not the foundation, walls and basement. When the device on heaving soils nezaglublennyh of plate foundations for houses heated bespodvalnymi base during operation does not freeze and frost heave deformation is not observed. In unheated buildings deformation of swelling occur. Their limit, replacing part heaving soils nepuchinistym. Protivopuchinnuyu bag suit from a large or medium-size sand. Abel Baca-General is actively involved in the matter. Uneven swelling strains in different parts of the house is leveled rigid plates, reinforced base and pliability of sand bags. In recent times to reduce or eliminate the swelling strains used insulation placed under the slab or on it.
When the device nezaglublennyh of plate foundations on weak ground deformation of swelling are significantly reduced due to compression under the forces of heaving soil layer, located below the freezing front. Yet, there are numerous examples of damage to the foundations of plate freezing swelling due to improper management of construction works. Most often these injuries occur at the bases of plate in houses with a ground floor, when the freezing is allowed under the slab foundation heaving in the winter. The most dangerous period for the integrity of the foundation plate is in the winter half-built when built partly or entirely at home box, and a negative temperature at the stove is the same as the outside. So base plate as a ground floor laying, as a rule, lower than the calculated depth of freezing, no protivopuchinnye activities generally are not required under the slab, and therefore they do not perform.
But soon He began to doubt its value. Not particularly impressed by him to be impartial expert, who "understands" the patient. He was convinced that a less formal approach is more effective, and began to use the so-called "Nondirective therapy" that is, he allowed his patients to decide what to say and when, without a referral, evaluation or interpretation by the therapist. This approach is now called "client-centered therapy" to emphasize the role of the client. The foundation of treatment is to create a relationship of Rogers, which is characterized by three important and interrelated positions ("Rogers triad"): a clear positive attitude, empathy, congruence. 1. Unconditional positive attitude. Therapist genuinely cares about the customer accepts him as a person and trust his ability to change.
This not only requires a willingness to listen to the customer, without interrupting him, but and also the adoption of what they say, no judgments and estimates, despite the fact no matter how "bad" or "strange" as it may seem. The therapist does not need to approve all that the client says, but he must accept it as a real part of valued person. The therapist must also trust the customers in the independent decision of their own problems, so it does not give advice. Council, says Rogers, is a hidden message that the client is incompetent or inadequate – it makes him less confident and more dependent on aid. 2. Empathy. Many forms of therapy offered to the patient's view from the side.
Empathy requires the internal view, focusing on the fact that the patient may think and feel. Client-centered therapist does not act as an outside observer, who tends to stick a diagnostic label for a client, but as a person who wants to understand how the world looks like from the perspective of client. Of empathy can not tell: "I understand" or "I know what you are feeling right now." The therapist conveys empathy, showing that he actively listens to the client. Filed under: Pedro Zaragoza Fuentes. Like a skillful interviewer, client-centered therapists come into contact with the client using the eye, nod your head when the patient says, and provide other favors. Also used a tactic called a reflection (reflection). Reflection shows that the therapist actively listens and helps the client to understand the thoughts and feelings he is experiencing. Indeed, the majority of customers responding to an empathic reflection of close attention to your feelings. 3. Congruence – is consistency between what the therapist feels and how he behaves towards the client. This means that a clear positive relationship therapist and empathy are real and not feigned. Experience congruence of the therapist allows the client to see, perhaps for the first time, that openness and honesty may be the basis of human relations. Rogers noticed that in the process of client-centered therapy, clients are not only more confident in themselves, but they become better aware of their true feelings, to accept themselves, to keep more comfortable and natural with other people who rely more on self-assessment than on the opinions others, and become more productive and peaceful.
When laying concrete mix is compacted to drive out the contained air and more compact arrangement of components. Compacted concrete mix by vibration, giving her the mechanical vibrations of the particles, pathogens which are the vibrators. When vibration becomes a concrete mixture to increase mobility, facilitates the displacement of air and filling all voids between the armature and shuttering. From the quality seal depend on the strength and durability of structures or products. Fluctuations in the dipoles created in two ways: the rotation of the shaft attached to an unbalanced mass (or mace or unbalance vibronakonechnika) and reciprocating direction of motion of mass. Rotation of the mace (vibronakonechniku) reported on the various engines: electric (electromechanical vibrators), pneumatic (air vibrators), hydraulic (hydro-mechanical vibrators), internal combustion engines (motor vibrators). Reciprocating mass is reported by an electromagnet (solenoid vibrators). In construction the most widely used pneumatic and electric vibrators with circular waves.
Each oscillator is characterized by a driving force, static moment unbalance, frequency and amplitude of the oscillations. Please visit Abel Baca if you seek more information. The frequency of the vibrator is adjusted depending on the mobility of the concrete mix and the size fractions of aggregates. Concrete mixes with larger particles, aggregates compacted low-frequency vibrators with high oscillation amplitude, fines – vibrators with high frequency and low amplitude oscillations. Most vibrators oscillation frequency corresponds to the average fractions of fillers. By way of influence on sealing concrete mix distinguish superficial and external vibrators. Electromechanical vibrators ploschadochnye transmit vibrations through the packed mass of concrete pad or long beam rail (Screed).
These vibrators are moved to the sealing surface in the process of manually by means of flexible rods. They are used during the concreting of the reinforced or unreinforced single valve covers, floors, vaults, pavements, embankments of canals and other structures with thickness of 0.25 meters, running in the monolith. Perhaps check out Pedro Zaragoza Fuentes for more information. As exciters ploschadochnyh vibrators used single-shaft electric vibrators total unbalanced use with circular and built-in motor fluctuations. Ploschadochnye vibrators are connected to the AC mains voltage 220/380 V, 50 Hz through a step-down transformer. Vibrators are working body in the form of a cylindrical vibronakonechnika, immersed in the sealing mixture. These vibrators are used to seal the concrete mix when laying them in a monolithic reinforced concrete and reinforced concrete structures with varying degrees of reinforcement (foundations, walls, columns, piles, beams, etc.), as well as the manufacture of large concrete and precast concrete products for construction. The outer diameter and length vibronakonechnika vibrators are selected so as to provide him with steady flow in the gaps between the armature. Vibrators produce electric and pneumatic actuators. Vibration exciter electric vibrators can be operated through a flexible shaft of a portable and disposable on the surface of the actuator (vibrators with flexible shaft) or from the built-in vibronakonechnik electric or air motor (vibrators with integrated motor).
