Description

BACKGROUND

Conventional tent, awning and canopy frame structures that can be assembled and disassembled are known. They are commonly made up of cylindrical tubing and various types of junction elements or connectors, or so-called slip fit or slip-on fittings, commonly termed corner, ridge intermediate, intermediate, three-way crown, four-way crown, six-way crown and eight-way crown fitting.

Often, the prior art systems do not include means for sealing against the weather and other environmental conditions at the joints where the various panels are joined. Another disadvantage is that the prior art shelters have to be built on unlevel ground, which is the normal situation. Unlevel ground poses a number of problems when a number of units have to be added to each other to produce a relatively large shelter.

Another shortcoming is that the prior art systems are not strong enough to support the tent and tent frame structure.

SUMMARY

The modular flooring system with scaffold understructure described herein provides a solution to the problems of the prior art systems. The system is capable of use with most clear span tent manufacturer's structures.

Clear span tents and frame structures are designed and manufactured in such a way that they can be assembled and disassembled at a site. The clear span tent and structures are temporary structures and they are used in the event rental industries most of the time. The clear span tent and the frame structures are designed be to setup on a leveled surface. Most of the clear span tent legs (uprights) are pinned to a base plate and the base plates are secured to a leveled surface. All of the base plates in a particular tent setup have to be on the same level. These base plates transfer the entire load from the tent to the ground or to a floor where the base plates are secured.

In the majority of the time the clear span tents and frame structures are not used on a leveled surface; instead they are used on an unleveled ground like golf courses. One or a few of the base plates may sit on the ground level but the rest of them are in a different elevation. In order to get a leveled surface for the base plates the customer has to create a platform. In the rental industry there are no engineered platforms designed to accommodate clear span tents and structures. So the customers use different staging products or they create a platform with scaffolding, wood and plywood.

The above mentioned poses the following challenges.

• • 1. Safety of the tent platform.
  • 2. These platforms are custom platforms and the load capacities of the platforms are questionable.
  • 3. Transferring the tent base plate reactions and the platform load to the ground is questionable.
  • 4. Most of the time there is no proper way securing the platform from uplift loads.
  • 5. No proper guide line to assemble a clear span tent on top of a platform.The system described herein provides a solution for all the above challenges because it is designed, engineered and manufactured to take different clear span tents and structures.

The engineered system solves many of the problems of prior art systems. First, the sides of the tent extend outside and below beam connectors. The enclosure system is economical and light weight in construction and provides for depositing rain water and snow on the ground outboard of the scaffold assembly.

Secondly, the tent and tent frame are supported by scaffold legs which support the engineered system. The platform does not support the tent and tent frame. Instead, the platform transfers the live load to the system scaffold legs. The upright connectors also transfer (Upright) load to the system scaffold leg. The beam may also transfer loads (platform live load, load from the tent and weight of the tent) to the system scaffold leg.

The tent floor can be 8″ from the ground to 15 feet or even more from the ground. As a result, this system may support a tent on very unlevel ground. The load is transferred to the ground through the legs.

The components may be as follows: universal beam, upright connector, beam connector, platforms, platform filler, universal saddle, and system scaffolding under structure.

Other objects and advantages will become apparent to those skilled in the art upon a review of the following detailed description of the preferred embodiments and the accompanying drawings.

DETAILED DESCRIPTION

Described is an engineered flooring system for clear span tents and the structures. The flooring system may have system scaffolding (under structures), and a flooring system. The understructure can be any system scaffolding as long as they have the right load capacity. Flooring systems may have the following items: saddle, universal beam, platform, and upright connectors. The base plates will be replaced by the upright connectors.

The upright connectors are specifically designed for tents so the customer has to use the right upright connector for the right tent. The flooring system accommodates most of the clear span tents and structures. When you use different tents from different manufactures customers have to use the specific upright connector for the specified tent. The universal beam, saddle and the platforms are the same for any type of tent.

The flooring system is designed to transfer the entire load coming from the platform and the tent; the load will be transferred to the scaffold legs. The universal beam, saddle and the platform will transfer live load to the legs and the upright connector will transfer the tent load.

The other advantages of this system are the flooring system is designed to go low as 8″ elevation to any platform heights. Also, the tent platform will be the exact size of the tent so the platform will not stick outside the tent. This makes the tent floor water proof because when it rains, the water will flow from the wall to the ground not to the platform.

FIG. 1 shows on embodiment of a scaffold system without a platform. FIG. 1 also shows scaffold system 10 including universal beam 12, upright connector 14 and saddle 16.

FIG. 1 also shows conventional scaffold components. For example, FIG. 1 shows connecting devices 30, horizontal posts 32 and scaffold legs 34.
