Beam formwork support system:
plywood is used for both the beam bottom template 10 and the beam side template 11, and joints of the plywood are planed and straightened by a hand plane to form hard abutted joints. A cleaning opening with the width of 100mm is reserved in the middle of the beam span and is plugged before concrete pouring. And the batten I2 adopted at the bottom of the top plate template is a batten of 100mm x 100 mm. The beam side template adopts a beam side batten I12 for the transverse inner edge, adopts a beam side batten II 13 for the vertical outer edge, and the inclined strut battens 18 are 50mm x 100mm battens. The wood beam is planed by a thicknesser with the distance not more than 300 mm. The longitudinal distance between the diagonal bracing battens 18 is not more than 600 mm. And a sealing rubber strip is additionally attached to the root of the beam bottom, so that slurry leakage is avoided. The two sides of the beam side template are fixed by using 100 round nails through rectangular wood, and then the beam side template is fastened by using a large-small head wood wedge. When the net height of the beam is larger than 800mm, the beam needs to be reinforced by using split bolts 19, and a PVC sleeve is additionally arranged in the beam. And after the mold is removed, the split bolt 19 is drawn out so as to be convenient for turnover use. When the span of the beam bottom template is more than 4.00m according to the design requirement, the arch camber is performed according to 2-3 per mill, and the reduction of the section size of the beam is avoided as much as possible. The beam bottom flitch one 14 is 100mm x 100mm flitch (length 300mm, length 200mm when the beam height > 850 mm). The beam bottom batten II 15 is placed on the steel pipe I17 and is 100mm multiplied by 100mm battens (400-600 mm long). The first steel pipe 17 and the second steel pipe 20 are arranged on the beam bottom support 16 and the common first bowl buckle support 7, and the first steel pipe 17 is a steel pipe with the diameter phi of 2-48.3 (the length is 1200mm, and when the height of the beam is larger than 850mm, the length is 600 mm). The top of the bowl mouth support I7 (with the length of 1500) is provided with an adjustable U support I6, and the U support I6 is provided with a batten II 3. The top of the beam bottom support 16 is provided with an adjustable U support, and the U support is provided with a beam bottom batten I14. When the beam width is less than or equal to 600mm, arranging a row of beam bottom supports 16 with the length of 900mm at the beam bottom along the length direction of the beam; when the width of the beam is larger than 600mm, two rows of beam bottom supports 16 are arranged at the beam bottom along the length direction of the beam, and the row spacing is not larger than 600 mm. The support root is padded with 50mm 100mm 400mm skid 8 on the concrete floor surface.
Roof template support system:
the top plate template 1 adopts plywood, a first batten 2 is 100mm x 100mm and is used as a main keel, a second batten 3 is 50mm x 100mm and is used as a secondary keel, and all the square timbers are pressed, planed and straightened. The plywood of the top plate template is connected with the first square timber 2 and the second square timber 3 by using round nails with the diameter of less than 50mm, so that long round nails are not required to be used for connection, and the panel is prevented from being damaged and the difficulty in detaching the template is avoided. When the span of the top plate is more than 4.0m, the arch camber is required according to the specification, and the arch camber height is as follows: 2-3 per mill. The top plate arch-camber follows the beam to move, the column angle descends, and the middle part ascends. The bowl buckle support I7 is provided with an adjustable U support I6 at the top. The supporting horizontal direction pull rods are mainly 1.50m, when the modulus is insufficient, the pull rods with the diameters of 1.20m, 0.90m and 0.60m are used for aligning, and the first row of pull rods use floor sweeping rods; when the supporting height of the top plate is more than 3.00m, the horizontal pull rod is not less than three ways, namely an upper way, a middle way and a lower way. When the longitudinal and transverse net span spans of the top plate template are larger than 2.50m, an early-dismantling method is adopted, and a plate belt type method is adopted for an early-dismantling system. The width of the wood plywood is 1220mm by taking a 1.50m pull rod as a reference, the middle distance of the plate strip is 1220+280=1500mm, the maximum distance from the beam flaw-piece is not more than 2000mm, the top of the early-dismantling support 5 is provided with an early-dismantling head 4, and the top of the early-dismantling head 4 is provided with a 280mm wide plate strip 9. The support root is padded with 50mm 100mm 400mm skid 8 on the concrete floor surface.
The size is only the commonly used size and can be adjusted according to actual conditions.
In conclusion, by means of the technical scheme, the stability of the template supporting system is ensured by adding the supporting points, the supporting and dismounting are fast, the middle stacking link of the turnover materials is avoided, the turnover of the materials is accelerated, the material consumption is reduced, and the investment cost is reduced; the early-dismantling formwork support system has the advantages of simple structure, flexible and convenient operation and easy mastering of the construction process, and compared with the conventional formwork supporting process, the early-dismantling formwork support system has the advantages that the working efficiency can be improved by about 2-3 times, the construction speed can be accelerated, the construction period is shortened, and the construction progress and quality requirements are met.
