Description

Method of transporting construction materials for high-rise buildings and their apparatus {Delivering of materials for High-Rise Building construction and apparatus thereof}

The present invention relates to a method and apparatus for transporting building materials for high-rise buildings, and more particularly, to a method and apparatus for transporting building materials for moving cement, sand, gravel, or cement mortar to a construction site or a concrete pouring site. , The transport method and apparatus of the present invention insert and fix a spring structure to which a plurality of blades are fastened inside the hose for elastic transport, so that the transport hose or sprin is not rotated and the construction material is transported without leaving any residue on the bottom of the hose. The present invention relates to a method for transporting building materials that can be easily and quickly transported in a curved direction and an apparatus therefor.

In general, a transfer screw is used to transfer powdery or semi-solid and liquid substances, and in particular, a pressure pump is used to transport liquid substances.

As an example of using the pressure pump, as shown in FIG. 1, a concrete pump truck (10; CPT; Concrete Pump Truck) is used to transport ready mixed concrete (REMICON) to a destination in a general construction site.

In the concrete pump truck 10, ready-mixed concrete is transported along the boom that connects the vertical transport pipe 100 and the horizontal transport pipe 100 with an elbow.

When the pressure for supplying ready-mixed concrete is applied to the conveying pipe 100 of the concrete pump truck 10 and then stopped, the ready-mixed concrete falls down by a natural fall in the vertical conveying pipe 100 associated with the boom, but the horizontal conveying pipe 100 ), the ready-mixed concrete is not transported well, and the gravel is concentrated in one place and remains in a specific part in the pipe, so that the inside of the transport pipe 100 in a specific part is blocked. At this time, if the user of the pump truck who does not recognize the clogging of the transfer pipe 100 continuously increases the pressure, a rupture phenomenon may occur at any specific portion of the transfer pipe 100 .

On the other hand, the concrete pump truck 10, which serves to transport the ready-mixed concrete, which is a hard slurry, from the ready-mixed concrete truck to reach the destination at the construction site is composed of a vehicle part, a cylinder part, a hopper part, and a transfer pipe 100.

Here, the conveying pipe 100 is a component that functions as a movement path of the ready-mixed concrete, and the conveying pipe 100 must have abrasion resistance and impact resistance.

The transfer pipe 100 is used to transfer ready-mixed concrete made by mixing cement, water, etc. with high-hardness minerals such as sand, gravel (crushed stone), and reclaimed aggregate, so abrasion is severe and in order to reach the high-rise pouring site Because it pushes the ready-mixed concrete with high pressure, high pressure and impact are applied inside the conveying pipe.

A specific part of the transport pipe 100 due to the high pressure in the transport pipe 100 for transferring the ready-mixed concrete blocks the specific part of the transport pipe 100 and the residue remaining in the specific part cannot be transported in the transport pipe 100 . is ruptured, the ready-mixed concrete leaks out of the transfer pipe 100 and the site is contaminated or the worker may be injured by the leaking ready-mixed concrete.

Therefore, when transferring the ready-mixed concrete to the transfer pipe 100, the development of a technology for transferring the ready-mixed concrete without leaving a residue of the ready-mixed concrete to the transfer pipe 100 was urgently required.

In addition, a means for transferring cement mortar such as ready-mixed concrete to a transfer screw is also known from the prior art. As a prior art for such a transfer screw, Patent No. 0384926 "Twin Transfer Screw" is disclosed in the Laid-Open Patent Publication (Patent Document) see 1). The prior art discloses a feed screw to which the principle of a working cell movable in the axial direction equal to twice the pitch length is applied. As another prior art for the transfer screw, Utility Model Registration No. 382603 "Transfer screw for dough dough" is disclosed in the Utility Model Registered Gazette (see Patent Document 2). The prior art discloses a feed screw having a first feed screw having a wide pitch interval from the central area and a second feed screw having a narrow pitch interval from the central area.

In particular, the known transfer screw of the prior art is characterized in that a spiral-shaped thread is fixedly formed around an axis inside a cylinder-shaped housing. In addition, this type of transfer screw has a disadvantage in that the amount of energy consumed is increased due to the pressure generated between the transfer materials and the pressure applied to the screw by the transfer material, and it is difficult to transfer more than a certain amount of construction material depending on the shape of the transfer material. there was

As a technique developed in the prior art to solve the problems of the prior art, "a rotary feeder and a cement mortar mixing device having a rotary feeder" of Patent Laid-Open No. 2010-0040565 is disclosed in the Laid-Open Patent Publication (Patent Publication). See literature 3).

In the rotary feeder for mixing and conveying raw materials, as shown in FIGS. 2 and 3, "a rotary feeder and a cement mortar mixing device having a rotary feeder" of the Patent Laid-Open No. 2010-0040565, one side a rotatable cylinder-shaped housing 11 with one side open and the other side open or closed; a conveying screw 12 attached to the inner surface of the housing 11 and extending from one side of the housing to the other side in a spiral shape; and a rotary feeder for mixing and transporting raw materials including a rotary shaft 13 coupled to one side of the housing 11, which reduces the energy consumption required for blending and transporting raw materials, and allows for uniform mixing It is possible and has the advantage that quantitative discharge is possible.

However, in the conventional techniques described above, only the transfer screw 12 installed in the pipe-type or cylindrical housing 11 rotates or the housing 11 itself rotates together with the rotation shaft 13 to transfer the cement mortar. It has a drawback that it consumes a lot of energy compared to the amount of transport, and the failure of the transfer screw occurs frequently due to the excessive load on the transfer screw during transfer. If the failure occurs, not only can it be used, but also the thread of the transfer screw until the failure occurs. This is easily worn and a gap is generated between the screw thread of the housing and the transfer screw. At this time, a part of the transferred cement mortar is not transferred and remains inside the housing, so there is a problem that the transfer of the cement mortar cannot be performed smoothly.

As such, if the cement mortar remains in a specific part of the housing, the inside of the housing at the lower end of the transfer screw is clogged. At this time, if a user who is not aware of the clogging of the housing continuously increases the pressure of the transfer pump, a rupture phenomenon occurs at the site where any specific cement mortar of the housing is left and accumulated, causing problems such as stopping the construction.

In addition, there was a problem that the transfer hose was not flexible, so it was impossible to transfer the building materials in the direction forming a curve, especially when constructing a high-rise building.
