El presente trabajo de investigación tiene como objetivo elaborar un plan de mejora de la gestión de procura del encofrado metálico con la finalidad de reducir la variabilidad en el costo final del alquiler de encofrado y apuntalamiento durante la etapa constructiva de edificios multifamiliares ejecutados en la ciudad de Lima metropolitana. Se analizaron datos de cinco proyectos ejecutados en Miraflores, Jesús María, Barranco y Lima Cercado en los cuales se registraron diferencias económicas negativas respecto al presupuesto inicial de alquiler de encofrado. Se realizo encuestas a las personas involucradas en el proceso de procura de encofrado para identificar las causas de estas variaciones de costo y mediante herramientas de gestión se determinaron cuáles fueron las de mayor incidencia. Finalmente se estableció un plan de mejora del proceso tomando en cuenta los defectos y omisiones encontrados en las gestiones de procura de los proyectos que se tomaron como objeto de estudio y además se incorporaron algunas herramientas que permitan mejorar la comunicación entre el constructor y los proveedores de los equipos de encofrado. / The objective of this research work was to elaborate a plan to improve the management of the metallic formwork procurement in order to reduce cost overruns in the formwork rental and shoring during the construction stage of multifamily buildings executed in the city of metropolitan Lima. Data from five projects executed in Miraflores, Jesús María, Barranca and Lima Cercado were analyzed, in which negative economic differences were registered with respect to the initial formwork rental budget. Surveys were carried out among the people involved in the formwork procurement process to identify the causes of these cost variations and through management tools it was determined which were the ones with the highest incidence. Finally, a process improvement plan was established, taking into account the errors and omissions found in the projects that were taken as the object of study, and some tools were also incorporated to improve communication between the constructor and the companies that rent the formwork equipment. / Tesis

Stéréotomie et vision artificielle pour la construction robotisée de structures maçonnées complexes / Stereotomy and computer vision for robotic construction of complex masonry structures

Loing, Vianney 22 January 2019 (has links)
Ce travail de thèse s'inscrit dans le contexte du développement de la robotique dans la construction. On s’intéresse ici à la construction robotisée de structures maçonnées complexes en ayant recours à de la vision artificielle. La construction sans cintre étant un enjeu important en ce qui concerne la productivité sur un chantier et la quantité de déchets produits, nous explorons, à cet effet, les possibilités qu'offre la rigidité en flexion inhérente aux maçonneries topologiquement autobloquantes. La génération de ces dernières, classique dans le cas plan, est généralisée ici à la conception de structures courbes, à partir de maillages de quadrangles plans et de manière paramétrique, grâce aux logiciels Rhinoceros 3D / Grasshopper. Pour cela, nous proposons un ensemble d'inégalités à respecter afin que la structure obtenue soit effectivement topologiquement autobloquante. Ces inégalités permettent, par ailleurs, d'introduire un résultat nouveau ; à savoir qu'il est possible d'avoir un assemblage de blocs dans lequel chacun des blocs est topologiquement bloqué en translation, mais un sous-ensemble — constitué de plusieurs de ces blocs — ne l'est pas. Un prototype de maçonnerie à topologie autobloquante est finalement conçu. Sa conception repose sur une découpe des joints d'inclinaison variable qui permet de le construire sans cintre. En parallèle, nous abordons des aspects de vision artificielle robuste pour un environnement chantier, environnement complexe dans lequel les capteurs peuvent subir des chocs, être salis ou déplacés accidentellement. Le problème est d'estimer la position relative d'un bloc de maçonnerie par rapport à un bras robot, à partir de simples caméras 2D ne nécessitant pas d'étape de calibration. Notre approche repose sur l'utilisation de réseaux de neurones convolutifs de classification, entraînés à partir de centaines de milliers d'images synthétiques de l’ensemble bras robot + bloc, présentant des variations aléatoires en terme de dimensions et positions du bloc, textures, éclairage, etc, et ce afin que le robot puisse apprendre à repérer le bloc sans trop de biais d’environnement. La génération de ces images est réalisée grâce à Unreal Engine 4. Cette méthode permet la localisation du bloc par rapport au robot avec une précision millimétrique, sans utiliser une seule image réelle pour la phase d'apprentissage ; ce qui constitue un avantage certain puisque l'acquisition de données représentatives pour l'apprentissage est un processus long et fastidieux. Nous avons également construit une base de données riche, constituée d’environ 12000 images réelles contenant un robot et un bloc précisément localisés, permettant d’évaluer quantitativement notre approche et de la rendre comparable aux approches alternatives. Un démonstrateur réel intégrant un bras ABB IRB 120, des blocs parallélépipédiques et trois webcams a été mis en place pour démontrer la faisabilité de la méthode / The context of this thesis work is the development of robotics in the construction industry. We explore the robotic construction of complex masonry structures with the help of computer vision. Construction without the use of formwork is an important issue in relation to both productivity on a construction site and the amount of waste generated. To this end, we study topological interlocking masonries and the possibilities they present. The design of this kind of masonry is standard for planar structures. We generalize it to the design of curved structures in a parametrical way, using PQ meshes and the softwares Rhinoceros 3D and Grasshopper. To achieve this, we introduce a set of inequalities to respect in order to have a topological interlocked structure. These inequalities allow us to present a new result. Namely, it is possible to have an assembly of blocks in which each block is interlocked in translation, while having a subset — composed of several of these blocks — that is not interlocked. We also present a prototype of topological interlocking masonry. Its design is based on variable inclination joints, allowing construction without formwork. In parallel, we are studying robust computer vision for unstructured environments like construction sites, in which sensors are vulnerable to dust or could be accidentally jostled. The goal is to estimate the relative pose (position + orientation) of a masonry block with respect to a robot, using only cheap cameras without the need for calibration. Our approach relies on a classification Convolutional Neural Network trained using hundreds of thousands of synthetically rendered scenes with a robot and a block, and randomized parameters such as block dimensions and poses, light, textures, etc, so that the robot can learn to locate the block without being influenced by the environment. The generation of these images is performed with Unreal Engine 4. This method allows us to estimate a block pose very accurately, with only millimetric errors, without using a single real image for training. This is a strong advantage since acquiring representative training data is a long and expensive process. We also built a new rich dataset of real robot images (about 12,000 images) with accurately localized blocks so that we can evaluate our approach and compare it to alternative approaches. A real demonstrator, including a ABB IRB 120 robot, cuboid blocks and three webcams was set up to prove the feasibility of the method

Zwei Anwendungsbeispiele für Textilbeton

Brameshuber, Wolfgang, Mott, Rebecca 03 June 2009 (has links)
In dieser Veröffentlichung werden 2 Anwendungsbeispiele für Textilbeton vorgestellt, ein nachträgliches Abdichtungssystem sowie eine bauteilintegrierte Schalung. Teil 1: Da in vielen Regionen Deutschlands steigende Grundwasserspiegel zu verzeichnen sind und bestehende Gebäude, die nicht für den Belastungsfall „drückendes Wasser“ ausgelegt sind, mit einem tragfähigen nachträglichen Abdichtungssystem ertüchtigt werden müssen, wurde ein entsprechendes Abdichtungssystem aus Textilbeton entwickelt. Durch die Verwendung des Textilbetons ist es möglich, ein Abdichtungssystem mit einer geringen Bauteilstärke von 30 mm im Spritzverfahren herzustellen. Teil 2: Die bauteilintegrierte Schalung (BIS) aus Textilbeton nimmt während der Betonage den Frischbetondruck auf. Im Endzustand bildet sie die Bauteiloberfläche und kann Anforderungen hinsichtlich Tragfähigkeit, Sichtbeton- und Oberflächenqualität sowie Oberflächenausbildung (Farbe, Struktur) erfüllen. BISElemente können werksmäßig wirtschaftlich und qualitativ hochwertig hergestellt werden.
