Referring to fig. 3 and 4, the second rectangular block 1 is formed by welding four steel bars 11. The steel bar 11 is a square steel pipe of 50X 3mm or an angle steel of 50X 3 mm. The cross section of the square steel pipe is 50 multiplied by 50mm square, and the thickness of the pipe wall is 3 mm. The steel bar can also be formed by welding two pieces of angle steel with the same shape, size and length. Each angle steel comprises two plate bodies which are perpendicular to each other, the width of each plate body is 50mm, and the thickness of each plate body is 3 mm. Each steel bar 11 is in the shape of a straight quadrangular prism, the bottom surface of the straight quadrangular prism is in the shape of an isosceles trapezoid, the width of each steel bar is 1.5mm, the height of each steel bar is 50mm, and the degree of the base angle of each isosceles trapezoid is 45 degrees. Of the four steel bars 11, two steel bars 11 have a length equal to the length of the long side of the template 2, and the other two steel bars 11 have a length equal to the length of the short side of the template 2. The reason why the steel bars 11 are designed in the shape of an isosceles trapezoid is to improve the welding strength between the steel bars 11. When four steel bars 11 are welded to form the second rectangular frame 1, the inclined surfaces between the two steel bars 11 are welded together, so that the strength of the second rectangular frame 1 obtained by welding is higher. And a steel bar mesh is arranged in the second rectangular square frame 1, and comprises a first steel bar 12 and a second steel bar 13 which are perpendicular to each other. The specifications of the first reinforcing steel bar 12 and the second reinforcing steel bar 13 are both phi 6 mm. The number of the first reinforcing bars 12 and the second reinforcing bars 13 is more than two. The distance between every two adjacent first reinforcing steel bars 12 is 200mm, and the distance between every two adjacent second reinforcing steel bars 13 is 200 mm. After the inner frame of the template 2 is prefabricated, concrete is poured into the inner frame to be vibrated, and then the template 2 is manufactured.
In this embodiment, the length of the steel bar 11 is determined according to the specification of the template 2 to be manufactured. The form 2 has a rectangular shape, wherein the lengths of two bars 11 are equal to the length of the short side of the rectangle, and the lengths of the other two bars 11 are equal to the length of the long side of the rectangle. The steel bar net sheet is welded at the middle position inside the second rectangular square frame 1, and the distance between the axis of the first steel bar 12 and the bottom surface of the steel bar 11 is 25 mm. The concrete used to prepare the form 2 includes water, cement, grit, stone chips, polystyrene particles and a foaming agent. In the process of manufacturing the tire formwork 2, the concrete needs to be vibrated and compacted, after the concrete is initially set, the surface of the concrete is pressed, and the flatness of the surface of the concrete is required to be not more than 5mm in the pressing process. And after the concrete is finally set, covering and curing the concrete for at least seven days.
Referring to fig. 5 and 6, the number of the tire mold plates 2 to be prefabricated is four. Firstly, the four tire templates 2 are put into a shaping and fixing assembly mold 3 for assembly, so that the four tire templates 2 are assembled into a rectangular square frame. Then, the intersection of two mutually perpendicular tire templates 2 is welded, and the length of the welding seam is 100 mm. In this way, all the intersections of the four panels 2 are welded, so that the four panels 2 can be assembled into a first rectangular frame. And the four outer corners of the first rectangular frame are respectively provided with a lifting ring 4 with the specification of phi 48.3 multiplied by 3mm and the length of 100mm, and the lifting ring 4 is welded on the outer corners of the first rectangular frame. When the first rectangular box needs to be hoisted, a hoist 5 needs to be used. The spreader 5 includes a fourth steel bar 51 and two fifth steel bars 52, and a lifting ring 53 is provided at the middle of the fourth steel bar 51. Two fifth reinforcing bars 52 are respectively provided at both ends of the fourth reinforcing bar 51, and the middle portion of each fifth reinforcing bar 52 is welded to one end of the fourth reinforcing bar. The two ends of each fifth steel bar 52 are respectively provided with a hook 54, when the first rectangular square frame needs to be lifted, the four hooks 54 are respectively hung on the corresponding lifting rings 4, and then the lifting rings 53 are lifted through the lifting equipment, so that the whole first rectangular square frame can be lifted.
Referring to fig. 7, the concrete pad 6 is marked with four marking lines 7, and the four marking lines 7 form a rectangle. Four tire templates 2 in the tire template system are arranged in one-to-one correspondence with the marking lines 7. The inner side of each marking line 7 is provided with a blind hole (not shown in the figure), and the blind hole is formed by arranging an electric drill on the concrete cushion 6. And a third steel bar 8 is embedded in each blind hole, and the third steel bars 8 are welded at the bottom of the corresponding tire template 2 to play a role in positioning the bottom of the tire template 2. The quantity of the blind hole on each sign line 7 is more than two, and the internal diameter of blind hole is not less than 14mm, and the degree of depth of blind hole is 50 to 60mm, and the length of third reinforcing bar 8 is not less than 100mm, and the distance between two adjacent blind holes is 1000 mm. If the length of the template 2 is within 1000mm, only one third reinforcing steel bar 8 needs to be welded at the bottom of each template 2. If the length of the core plate 2 exceeds 1000mm, two or more third reinforcing bars 8 need to be welded to the bottom of each core plate 2 in order to fix the bottom of the core plate 2 better.
In this embodiment, a wood purlin 9 and a support 10 are further disposed inside the first rectangular square block, and the wood purlin 9 is a wood purlin with a specification of 50 × 100 mm. The support member 10 includes a connecting steel pipe 101 of a diameter of 48.3 mm and two support heads 102, and the two support heads 102 are respectively disposed at both ends of the connecting steel pipe 101. In fig. 7, two wood purlins 9 are arranged on each tire template 2, and the two wood purlins 9 are respectively arranged at positions close to two ends of the tire template 2. Two support heads 102 on the same support 10 abut against the wood balms 9 on the two opposite tire formworks 2 respectively. The supporting head 102 abuts against the middle of the wood purlin 9, so that the wood purlin 9 is tightly attached to the inner side wall of the tire template 2. In order to prevent the mutual interference between the steel connecting pipes 101, the steel connecting pipes 101 of different supporting members 10 are located at different heights. The support head 102 applies pressure to the middle position of the tire mold plate 2 through the wood balk 9. When earth backfilling is performed around the first rectangular frame, the supporting head 102 can counteract the lateral pressure of a part of backfilled soil on the tire template 2, so that the situation that the installation quality of the tire template system is affected due to the fact that the pressure of the backfilled soil on the lateral wall of the tire template 2 is too high is prevented.
Referring to fig. 8, after the earth backfilling is completed around the first rectangular square frame, the supporting members 10 and the wood beams 9 are removed, and the waterproof material 14 is laid inside the tire template system. The waterproof material 14 may be a waterproof paint, and is coated on the inner surface of the tire template system by painting. The waterproofing material 14 may also be a waterproofing membrane that may be applied to the inner surface of the tire template system. The waterproof material 14 can prevent water leakage due to the occurrence of fine cracks inside concrete after the concrete in the form system is molded.
While the present invention has been particularly shown and described with reference to the present embodiments and preferred versions thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
