Prefabricated steel reinforcement cage 3 of installation on bottom template 1, support between steel reinforcement cage 3 and the bottom template 1 and be fixed with the cushion (not shown in the figure), the cushion can adopt and precast with the same material of concrete that pours in advance to form for prop up steel reinforcement cage 3 and form one section clearance with bottom template 1. And split heads ribs 6 are fixed between grids of the steel reinforcement cage 3, and the split heads ribs 6 are used for supporting and controlling the distance between the surface layer template 2 and the bottom layer template 1.
Then, a surface layer template 2 is laid, and the surface layer template 2 is installed in a grading mode according to the typesetting requirements when laid. Be equipped with a plurality of reinforcement ribs 8 along slope incline direction on the surface course template 2, reinforcement rib 8 can be rectangular form steel side's pipe to reduce surface course template 2 and take place the possibility of warping after pouring, can adjust the distance between two square pipes as required if 100mm, 150mm, 200mm etc. nevertheless must not exceed 250mm, and the distance control between two adjacent square pipes of this place is 200 mm.
Fixed connection is between surface course template 2 and the bottom template 1 through a plurality of 5 fixed connection of fixed establishment, and fixed establishment 5 is including wearing to locate the opposite-pulling screw 51 on the bottom template 1 perpendicularly, be located 8 upper portions of strengthening rib and perpendicular to strengthen the depression bar 52 that rib 8 placed and the locating part 53 on the opposite-pulling screw 51 is located to the cover, and the both ends threaded connection of opposite-pulling screw 51 has the nut.
The counter-pull screws 51 are distributed on the bottom formwork 1 in a rectangular array, the distance between two adjacent counter-pull screws 51 is within 500mm, such as 300mm, 400mm, 450mm and the like, but not more than 500mm, and here, the distance between two adjacent counter-pull screws 51 is controlled at 500 mm.
The pressing rod 52 can be a circular steel pipe, the limiting member 53 is a sheet-shaped iron casting or steel part, a through hole for the opposite-pulling screw 51 to pass through is formed in the middle of the limiting member 53, and an arc-shaped limiting groove 531 matched with the outline of the circular steel pipe is respectively formed in each of two sides, located on the through hole, of the limiting member 53. After the limiting groove 531 of the limiting part 53 is abutted to the pressing rods 52, the limiting groove 531 can prevent the two pressing rods 52 from being away from each other and shaking, meanwhile, the limiting part 53 compresses the pressing rods 52 under the limitation of nuts, the pressing rods 52 are prevented from being away from the surface layer template 2 and moving, the rigidity between the surface layer template 2 and the bottom layer template 1 is improved, and the possibility of expansion die deformation between the poured surface layer template 2 and the bottom layer template 1 is greatly reduced.
S3: preparing an intermediate cover plate 4:
and respectively placing the middle cover plates 4 which are adaptive to the widths of the reserved pouring belts at all levels on the surface layer templates 2 at the upper parts of the corresponding reserved pouring belts for standby. Such as the intermediate deck boards 4 for covering the primary ready-cast strips 25, are placed in a sufficient number on the secondary panels 22. To avoid confusion, the intermediate lid 4 is numbered beforehand.
S4: pouring concrete in layers and tamping:
fully watering and wetting the template in advance before pouring the concrete, and adjusting the slump of the concrete. When concrete is poured, the concrete is poured symmetrically from bottom to top in a grading mode, and the pouring direction is gradually carried out along the direction parallel to the length direction of the ridge. The operation of tamping is carried out while pouring, avoids the phenomenon of leaking to shake, and the compactness of concrete is improved to supplementary tamping through watering and tamping reservation mouth 7 at this in-process. And after pouring and tamping, the middle cover plate 4 is installed in a grading way according to the cover plate number and is firmly reinforced by bolts.
And after the lower circle of concrete is completely poured and tamped, the pouring and tamping operation of the upper layer is carried out, and meanwhile, the plugging work of the pouring and tamping reserved opening 7 of the lower layer is well carried out. When pouring and smashing, the baffle is placed at the feeding port, concrete is prevented from overflowing to the surface layer template 2, and the height of the baffle is larger than 500 mm.
And after pouring is finished, maintaining according to the operation instruction, and removing the template after the strength meets the design requirement.
Comparative example 1
The difference from the embodiment is that the tamping operation is performed without the pouring and tamping reserved opening 7.
Comparative example 2
The difference from the examples is that the pitch of 25% of the square tube was controlled at 350 mm.
Comparative example 3
The difference from the embodiment is that the spacing between the 25% square tubes is controlled at 350mm, and the spacing between the 25% area region opposite pulling screws 51 reaches 900 mm.
Comparative example 4
The difference from the embodiment is that the width of the layered casting is up to 1500 mm.
Comparative example 5
The difference with the embodiment is that the pouring and tamping reserved opening 7 is not arranged for tamping operation, and the layered pouring width reaches 1200 mm.
The construction effects of the examples and comparative examples 1 to 4 were examined in a random sampling manner, and the effect data are shown in table 1.
Table 1 comparison of the effects of the embodiment
Figure BDA0002658367400000061
As can be seen from table 1, measures such as the arrangement of the pouring and tamping reserved opening 7, the control of the layered pouring distance and the distance between the square pipes and the like can jointly improve the concrete compactness poured by the inclined roof.
Data analysis of the embodiment and the comparative example 1 and the comparative example 4 shows that the concrete filling of the next layer can be more densely filled when the pouring and tamping reserved opening 7 vibrates, but if the distance of layered pouring is increased to exceed 900mm, concrete at a longer distance cannot be vibrated and compacted through the vibrating of the pouring and tamping reserved opening 7, and the number of pitted surfaces of the concrete honeycomb is greatly increased. The data show that the mold expansion situation is better than that of the comparative example 1 and the comparative example 4, because the comparative example 1 lacks the pouring and tamping reserved opening 7, the concrete filling is not dense enough, and the comparative example 4 cannot be vibrated and compacted due to the long grading pouring distance, and when the rigidity of the template is better, the mold expansion phenomenon is not easy to generate.
Data analysis of the embodiment and the comparative examples 2 and 3 shows that the compaction degree of concrete can be improved and the phenomenon of concrete honeycomb pitted surface can be reduced by vibrating the pouring and tamping reserved opening 7. However, when the formwork expansion occurs due to insufficient rigidity of the formwork, the pitted surface of the concrete honeycomb and concrete cracks are increased, because the volume of the formwork expansion is increased, and the pitted surface of the concrete honeycomb cannot be generated by supplementing when local concrete is solidified.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
