[0002]

[Prior art]

 It is well known that concrete columns have been used for constructing windbreak nets and tide nets, and for constructing large-scale greenhouses for agriculture. When constructing the concrete pillar, a hole is dug deeply with an auger and the root portion of the pillar is buried, but at this time, the root portion must be particularly long because of the bearing capacity. is there. Especially in the Okinawa region, windbreak nets and tide nets are required, and large vinyl houses are built as greenhouses for growing fruits such as papaya or houseplants, which is also the main production area of sugar cane. Because of this, since the soil in the fields is cultivated deeply, there is a problem that it is difficult to obtain soil resistance and N value. In the method of burying only the support pillar, if the required height of the support pillar was 6 m, the root portion would need to be about 5 m, which not only increased the unit price of the support column itself, but also increased the unit price of the auger work for digging holes. Is the reality. In consideration of such a situation, a root entanglement is attached to the root insertion part, and the branch wire is further tensioned to try to pull out the column and prevent falling.However, the root entanglement is attached using a mounting bracket, Further, it takes a long period of time to bury a concrete branch line block at a position away from the column and to tension the branch line wire above the column from the branch line block, which requires a long construction period and is expensive in terms of cost.

[0003]

[Problems to be solved by the device]

 The Applicant tried to solve such a problem, and fixedly attached a root entanglement to the root of the concrete prop using a fitting, and further embedded a branch line block at a position distant from the post to form the branch line block. In order to improve the conventional concrete strut construction in which the top of the strut is tensioned with a branch wire, the problem is to improve the concrete strut itself to shorten the construction period and reduce the unit cost.

[0004]

[Means for solving problems]

 In view of the above problem, the present invention forms a entanglement provided at a predetermined position of the root insertion portion of the stanchion integrally with the stanchion body, and extends the entanglement near the top of the stanchion body along the protrusion direction of the entanglement. Through holes are formed in the vertical direction in the vicinity of both ends of the root entanglement, and both ends of the branch wire wires inserted in these through holes are fixed on the lower surface of the entanglement and the turnbuckle is attached. It is a strut used for a windbreak net that is strained via a tie.Furthermore, a root entanglement is fixed at a predetermined position of the root insertion part of the stanchion, and a through hole is formed near the top of the stanchion along the protruding direction of the entanglement. At the same time, the through holes are made in the vertical direction near both ends of the root entanglement, and both ends of the branch wire wires inserted into these through holes are fixed on the lower surface of the entanglement and tensioned through the turnbuckle. It is a pillar used for a windbreak net etc. In this case, the root entanglement provided at a predetermined position of the support post is formed integrally with the main body of the support post, and the metal fittings are provided near the top of the support main body in the protruding direction of the entanglement.

[Effect of device]

As described above, according to the present invention, the root entanglement 2 provided at a predetermined position of the root insertion portion 3 of the stanchion 1 is integrally formed with the main body of the stanchion 1, and the root entanglement 2 is provided near the top of the main body of the stanchion 1 along the protruding direction of the root entanglement 2. Along with the through holes 4 being formed, through holes 5 and 5 are vertically formed in the vicinity of both ends of the root entanglement 2, and the branch wire wires 6 and 6 inserted into these through holes 4, 5 and 5 are provided. Both ends are root-entangled 2 Fixed on the bottom surface 7, 7 and are tense via a turnbuckle 8 A pillar used for a windbreak net, etc. Furthermore, the root-entangled 2 is fixed at a predetermined position of the root-inserted portion 3 of the pillar 1. Then, through holes 4 are formed near the top of the pillar 1 along the protruding direction of the root entanglement 2, and through holes 5 and 5 are formed in the vertical direction near both ends of the root entanglement 2, respectively. Both ends of the branch wires 6 and 6 inserted into these through holes 4, 5 and 5 are fixed on the bottom surface of the entangled wire 2 and fixed. 7, 7 and a pillar used for a windbreak net which is strained via a turnbuckle 8. Further, a root entanglement 2 provided at a predetermined position of the pillar 1 is formed integrally with the main body of the pillar 1. , struts 1 their respective engagement portion 4 ₁ in the protruding direction of Negarami 2 near the top portion of the main _body, 4 ₁ with attaching metal fitting having a locking portion upward in the vicinity of both end portions of the root entanglement 2 The metal fittings provided with 5 ₁ and 5 ₁ are attached, respectively, and the branch wires 6 and 6 connected to the locking portions 4 ₁ and 4 _{1 of} the column ₁ and the locking portions 5 ₁ and 5 ₁ of the root entanglement 2 are turnbacked. It is a strut used for a windbreak net or the like which is strained via 8, and further, the root entanglement 2 is fixed at a predetermined position of the root insertion portion 3 of the stanchion 1, and the root entanglement 2 is protruded in the vicinity of the top of the pillar 1. The metal fittings provided with the locking portions 4 ₁ and 4 ₁ are attached, respectively, and the upper portion is also attached near both ends of the root entanglement 2. Fittings provided with locking portions 5 ₁ and 5 ₁ on _one side are attached, respectively, and the branch wire 6 connected to the locking portions 4 ₁ and 4 _{1 of} the column ₁ and the locking portions 5 ₁ and 5 ₁ of the root entanglement 2 , 6 are columns used for windbreak nets that are strained via turnbuckle 8, so when constructing conventional columns for windbreak nets, tide nets, or large concrete greenhouses, etc. In particular, it was necessary to lengthen the rooted part, but especially in the Okinawa region, because the soil of the field is cultivated deeply due to sugar cane cultivation, it is difficult to obtain ground resistance and N value. Yes, with the method of burying only the columns, if the required height of the columns is 6 m, the root portion will need to be about 5 m, which not only increases the unit price of the column itself, but also increases the unit price of the auger work for digging holes. It was the actual situation, To solve such a problem, the root entanglement is attached to make the root insertion part as shallow as possible, and the branch wire is further tensioned to try to pull out the pillar and prevent it from falling. It is time-consuming and expensive from the viewpoint of cost to tie them together and to embed a concrete branch line block at a position further away from the column and to tension the branch line wire above the column from the branch line block. However, in the present invention, since the pillar 1, the root entanglement 2 and the branch wire 6 are integrated, the erected pillar 1 has the root entanglement 2 not only for the purpose of preventing pulling out and falling, but also Since the entanglement 2 serves as the fulcrum of the branch wire 6, the tensile force component against the stress is borne, and in addition, the compressive force of the concrete support column 1 can resist wind force, and the root entanglement 2 is pressed by soil. Are In the branch line wire 6 is made possible to act sufficiently as a tensile force. According to the present invention, even if the required height of the support pillar is 6 m, the depth of the root-entry portion can be set to about 2.5 to 3 m, which is a very remarkable practical effect.
