Description:
MOLD FOR PRECAST REINFORCED CONCRETE HEAVY DUTY RETAINING WALL

TECHNICAL FIELD

The present invention pertains generally to retaining walls. Specifically, the invention related to installation relates to mold for precast reinforced concrete heavy duty retaining wall for completely of mass products.

BACKGROUND ART

Precast reinforced concrete heavy duty retaining wall WO/2018/160143 this innovation products modified from Precast reinforced concrete walls H shape WO/2015/ 199622. The objective of these innovation desired to evolution the traditional construction methods cast-in-place concrete walls change to Precast concrete wall.

Precast reinforced concrete wall H-Shape, the prior art Publication number WO/2015/199622 have two types of Blocks, a full block and a half block. The installation process is very bard and complicated, cause these products are very large size of block, very heavy, difficult to cast from complicated of mold and methods of wall installation, and methods of embedded horizontal rebars in both wall panels are not flexible and not suitable.

The molds of Precast reinforced concrete heavy duty retaining wall are steel structure, convenient to disassemble and assemble, it is stable and strong to withstand long term use. Easy to moved to the construction site, reduce the shipping and damages occurred.

Having thus generally described the nature of the invention, particular reference will be made to the accompanying drawing, shown by way of illustration preferred embodiments thereof and in which. BRIEF DESCRIPTION OF DRAWINGS

Wall thickness (6) and the center of wall thickness of Front face (3) having Straight-ridge (7). And at the center line of wall thickness (6), of Rear edge line (4), and the left edge Line, the right edge line (5) having grooves (8) at three sides, the size of all grooves are the same center and equal in all respect. When take Straight-ridge attached to the rear groove, it would be fit together. The rear area of Front face (2) from Front edge line (3) to Rear edge line (4) having four fin (9), the distance of each fin are equally, parallel, and parallel to left and right edge line (5). Tips of each lower fin (9) having Regular octagon columns (10) and homogeneous to each fin, the top surface of right hand and left hand of outer left and outer right of Regular octagon columns having Protrude male Interlocking (11), on the contrary the rear surface of Regular octagon columns (10) having Female Interlocking (12) the center line corresponds to Protrude male Interlocking (11) attached to female Interlocking (12), it would be fit together. Each fin (9) having many round holes (13) each round hole from Left hand fin passed to right hand fin, any one hole are concentric line for inserted horizontal rebars. The lowest sides of Regular octagon columns (10.) having four Rear sides surface (14).

Laying characteristic of Precast reinforced concrete heavy duty retaining wall (1), Front face (2) is in a face -up manner, when removed from mold.

As shown in Fig.2 is a perspective view of mold for Precast reinforced concrete heavy duty retaining wall (15) having Front Panel (16), Rear Panel (17) Left and Right Panel (18), and Central parts group (19). The material of mold mostly are steel. Method to disassemble, first removed Front Panel (16), and Rear Panel (17). Second removed both left and right panel (18), then removed Central parts group (19).

As shown in Fig. 3 is a plan view of Mold for Precast reinforced concrete heavy duty retaining wall mold (15) divided in to five parts as follows. First is Front Panel (16) which having Straight- ridge female mold (20), and a pair of Left and Right protrude female mold (21).

Each parts as mentioned above could be assemble before cast and disassemble parts (28) after cast.

The lower group is none disassemble parts (29) most upper parts of lower group are Support rail (30) which fastened to Equal leg angle frame (31) without removing and fastened to Form work panels (25), Left and right Panels which could be disassemble and assembled with bolts, the length of Support rail are equal to the length of Form work panels (25), there are eight Support rail in one mold. Equal leg angle frame (31) for Supported and laid along Support rail (30) the amount of them are not less than four pieces. The lower parts are H-beam (32) there are four H-beam in one mold, Using for supported along the Regular octagon columns attached to Rear side surface (14), the length of them are equal to the length of Support rail (30). The parts between Support rail (30) are Roller (33) using for mobility in sliding From work panels after cast, the amount of them are equal to the amount of equal leg angle frame (31). The lowest frame for Supported all upper loads are Support base (34). After assemble both Formwork Panels

(25) included Equal leg angle frame (31) and H - beam (32), they would be takes Regular octagon shape (35).

As shown in Fig. 6 and Fig. 7 is a steel tubes (27), inside round hole having Bolt insert rod (36) inserted in one side of hole attached inside surface of steel tube (27) and attached to the Fin (9) the external of Bolt insert rod locked to the Fin by the used of External snap ring (37) in the opposite having Internal thread rod (38) inserted in opposite direction of Bolt insert rod (36) and locked of said, then inserted Bolt (39) passed to Internal thread rod (38) and tighten.

Central box (24) the figuration as trapezoid assemble at central beside a Pair of Formwork Panels (25) and at the lower surface having holes attached nuts of Form work panels and fastened with bolts.
