Concrete

We use Glass Fiber Reinforced Concrete (GFRC) and wet-cast concrete to create specific concrete products. We spray GFRC into molds to create larger scale panels with intricate surface detail. GFRC can also be hand-sculpted onto steel frames, which we use to create more sculptural elements like 3D figures, animals and highly customized designs. We use wet-cast concrete to mold solid objects with precise detail.

Research-floor material/method

Wet pour rubber is the EPDM (Ethylene Propylene Diene Modified) rubber granules that form the basis of wet pour playground safety surfacing.  Other fixed play surfaces such as Notts Sport Childsplay are polypropylene, but some ChildsPlay systems do incorporate the use of rubber crumb.

The majority of black, wet pour playground surfaces are made from recycled car tyres.  This is a positive step, as disposing of old car tyres has always been difficult and had adverse environmental impacts.

There is both a mechanical and chemical method for reclaiming the materials that the rubber granules are made from:

  1. The mechanical method involves cutting the tyres into pieces and passing them through a mechanical grinder.  A number of passes are required in order for the tyres to be cut down into small enough pieces to make them workable when they are laid as wetpour playground safety flooring.  Following this, large magnets remove any metal contaminants from the rubber crumb.
  2. The chemical method involves the tyres being melted over metal gauze.  The molten rubber is allowed to pass through the gauze and into cold water.  The temperature change caused by the water rapidly cooling the molten rubber, makes the rubber form into granules.  The size of the rubber granules is determined by the size/gauge of the gauze used.

Different sizes of wetpour rubber are used for different applications.  For instance the smallest granules (1-2 mm is this correct) are used in the Notts Sport Childsplay 90/120 system, where as medium sized granules (1-4mm) are used in the wearing course of wetpour rubber.  The largest sized granules (2-8mm) are used in the base course of wet pour safety surfacing.

Initially rubber crumb was resin bound in pre-cast tiles, which were a common form of playground surfacing.  Although it was easier to install, it was very susceptible to vandalism and ultimately ended up costing local authorities/parish councils too much to maintain.  Hence one piece, poured wet pour was created.  Look at the wet pour page for further information.

Groundwork and Leisure Services (GLS) offer a nationwide installation service for wet pour play area surfacing.  Many councils are however, opting to install Notts Sport ChildsPlay system, as they offer all the benefits of wet pour with a higher level of vandalism resistance and therefore longevity.  GLS therefore encourage would be clients to consider Notts Sport as potentially the best playground surface on the market.

Prototype development

  1. the old model only involves waist movements.
  2. in the 1st draft, aesthetics were not taken consideration yet
  3. The new model aims to become a system of tools/equipment that will engage isolated body parts to perform movements extracted from Taichi.   Therefore, there would be equipment cater to legs, waist, hands, arms separately. Furthermore, considering working adults would not be in exercise attire during office hours and they might just have few mins during their break, all movements could be considered as “N.E.A.T — non-exercise activities thermogenesis”. So users could do gentle movements with the help of the facilities.  Besides, this would enable more than 2 people to use this tools at the same time; hence, it would also be a good chance for people to talk and interact during their break.
  4. In terms of aesthetic, I would like to use the traditional taichi symbol as inspiration.  First of all this symbol is well-known by all most everyone, using it would be an obvious reminder for users that this facility is related to Taichi. Secondly, this symbol well expresses the ideology behind Taichi, which is ” balance ” “movements” “duality”, therefore, I would like to play with the iconic “black and white” color of Taichi symbol.
  5. I propose to use the combination of wood and metal to build this system to create the modern look. Normally, manufacturers use metal alloy to build this kind of facility because they are more likely to be put outdoor.

Taichi style tree – ( why I choose 24 forms of yang style)

taichi-tree            yang-style

1. How did Tai Chi begin?

There are two theories

Theory #1
Around the Yuan and Ming Dynasty – Chang Sanfeng – about 600-700 years ago lived in Shaolin Temple and went to WuDang Mountain and created Tai Chi. He saw a crane fighting with a snake. The crane was always hard. The snake would yield and follow the crane and did not resist and so he didn’t lose his life to the crane. Hard was controlled by soft.
Theory #2
Created by Chen Family about 300 years ago by Chen Wangting.

2. What are the 13 Postures (original name of Tai Chi Chuan)?

The 13 Postures are comprised of 8 energies and 5 steps:

8 energies are: ward off, roll back, press, push, pull, elbow strike, shoulder strike, and split

5 steps are: forward, back, look left, gaze right, and center

3. How many styles of Tai Chi are there and what are their differences?

There are 5 different styles of Tai Chi that are connected with each other. Chen, Yang, Wu, Wu and Sun styles. All 5 styles are connected together; their outside movements are a little different but inside the energies are the same.

Chen Style – is fast and slow combined together with some jumping and stomping movements. Old form and cannon fist was created from the 17th generation.

Yang StyleYang Luchan learned the old form/frame from the Chen family. Yang movements are slow, even, gentle, big and large. Yang Luchan learned from the 14th generation Chen family member.

Wu/Hao Style – The 1st Wu style came from Yang and Chen styles and is slow, smooth, and small and the posture is high. Wu Yuxiang learned from Yang Banhou, 2nd generation Yang family member, and then learned from Chen Qingping, 14th generation. Wu/Hao is a smaller frame.

Wu Style – 2nd Wu style comes from Quanyu who learned from Yang Banhou. They lean their body to the side but when they lean they think about being straight. Wu learned from Yang Banhou. Later in age Banhou’s frame became smaller.

Sun Style – learned from Hao Weijian. Their movements combine 3 styles of Tai Chi together, Wu, Hsing-I and Bagua.

4. Who created each of the 5 styles?

Chen was created by Chen Wangting
Yang was created by Yang Luchan
Wu/Hao was created by Wu Yuxiang
Wu was created by Wu Jian Quan or Wu Quanyu
Sun was created by Sun Lutang

5. Who did the creators learn from?

Yang Luchan learned from Chen Changxin
Wu Yuxiang learned from Yang Luchan, Yang Banhou and Chen Qingping
Wu Jianquan learned from his father, Quanyu
Sun Lutang learned from Hao Weijian

6.  The most practised form now.

The Beijing 24 Form was the result of an effort by the Chinese Sports Committee, which, in 1956, brought together four Taiji teachers – Chu Guiting, Cai Longyun, Fu Zhongwen, and Zhang Yu – to create a simplified form of Taiji as exercise for the masses. The creators truncated the traditional family style Taiji forms to 24 postures; taking about six minutes to perform and to give the beginner an introduction to the essential elements of Taijiquan, yet retain the traditional flavor of traditional longer hand forms (in general, 88-108 postures). Henceforth, this form was avidly promoted by the People’s Republic of China for general exercise, and was also taught to internees in Communist “re-education” camps. Due to this official promotion, the 24-form is most likely the Taiji form with the most practitioners in China and the world over.
