Description

New construction joint for logistics warehouse {EXPANSION JOINT FOR WAREHOUSE}

The present invention relates to a new joint for a distribution warehouse, and more particularly, by improving the strength of the cover plate through structure and material improvement, and by applying a reinforcing structure, it is possible to increase durability compared to the existing one, while maintaining stable fixation. It can be secured and prevented from bending and deformation of the cover plate exposed on the floor, and vertical displacement due to floating settlement as well as horizontal displacement due to temperature change can be prevented. It relates to a new joint for a distribution warehouse that prevents the detachment of the cover plate, etc., as well as prevents damage to the joint side of the new construction.

In general, a distribution warehouse is a storage warehouse for temporarily or long-term storage of all items used in daily life such as various food and beverages, clothes, home appliances, and miscellaneous goods produced in large quantities at a factory or production site. Away from the management dimension of logistics, we aim to create new business such as product placement in the storage inventory in the warehouse, efficient storage and delivery, and inventory management, as well as more efficient use of the logistics loading space as well as faster loading and unloading of mass-produced goods. It is designed and constructed to store a large amount of logistics through

In the design and operation of such a warehouse, the pallet rack, which has a width and height in which pallets of a certain standard can be put in and out, is divided into each aisle section, and is designed vertically in multiple stages, and logistics costs are reduced by using special vehicles such as forklifts. It is operated so that the pallet in the loaded state is filled and stored in the pallet rack.

In addition, in the case of wanting to release the logistics in the loaded state, a special vehicle such as a forklift is used to move the logistics by lifting the pallet in the loaded state.

These warehouses are structures that can be made of various structural materials, and usually have a concrete base layer and a floor surface with a mortar finish layer.The floor surface for distribution warehouses is the flatness for loading and unloading the logistics. When used, the robustness that can withstand the weight of logistics and forklifts stands out as a very important factor.

In addition, in distribution warehouses where the flatness and solidity of the floor surface are very important factors as described above, cracks occur due to expansion and contraction according to the temperature change of the concrete on the floor surface, deformation of the concrete structure, and antifreeze settling or vibration prevention. It has a configuration of constructing a joint such as an expansion joint at this expected position.

In addition, in most distribution warehouses, since it is a place with a special characteristic where the lifting and unloading work using a forklift, which is a considerable weight, is essentially performed, the SM400 material and a thickness of about 9mm as a flat plate on the upper surface to protect the new joints constructed on the floor surface. It is used in the form of mounting and disposing a steel plate (cover plate) having a.

However, conventionally, the steel plate, which is a cover plate, is simply seated on the floor without a stable fixing means, or even if there is a fixing means, the steel plate (cover plate) is easily lifted or rattled when moving through a heavy forklift or the like. Because the sound is generated, it acts as a hazard to workers working in the distribution warehouse, and acts as a factor that hinders the work environment.

In addition, the steel plate (cover plate) that is used by placing it on the floor of the distribution warehouse has a problem in that warpage or other deformation occurs due to the weight of the forklift, which acts as a risk factor when using the forklift when moving inside the distribution warehouse. In addition, there are problems such as the steel plate (cover plate) being pushed out of the placement position or falling down, and there is an urgent need for improvement in the field.

Incidentally, heavy forklifts have wheels made of urethane material, and they generate concentrated loads on the steel plate (cover plate) or the expansion and contraction joint, and easily cause deformation such as bending of the steel plate (cover plate).

In addition, in the new joint part of the conventional distribution warehouse, the use of a heavy forklift and frequent movement are performed, so that damage to the expansion joint side corresponding to the joint part of the floor structure occurs, and this may cause unequal settlement. There was a problem that a height difference may occur due to differential settlement.

Furthermore, in the area of the new joint of the conventional distribution warehouse, a change occurs in the width of the expansion joint side due to the temperature change in Samhansaon, especially in summer and winter.Therefore, a gap is generated, the gap is gradually widened, and the damage is extended. There was this.
