Abstract

The utility model relates to a prefabricated thin wall box. The main body of the prefabricated thin wall box is a square box, fibre roving cloth is prefabricated in the walls, the top plate the bottom plate of the box body, a steel reinforcement is prefabricated in the bottom plate in long direction and transverse direction at least one direction, a supporting upright wall is arranged between the top plate and the bottom plate of the box body, the supporting upright stand wall is a single partition wall type supporting upright wall, a decussation type supporting upright wall or a diagonal type crossed upright wall and both heads of the steel reinforcement extend out of the bottom plate. The structure is adopted to make the prefabricated thin wall box have good anti-tread and compressive properties, and the need of site operation is nicely satisfied; in addition, after the steel reinforcement is prefabricated in the thickening bottom plate of the thin wall box, the thin wall box can be directly put on a moulding plate before depositing concrete, the thin wall box and the concrete form a whole after depositing concrete, the thickening bottom plate can directly reveal to be used as a ceiling plate, and simultaneously, after the exerted steel reinforcement head and the cast concrete are coagulated to a whole, the exerted steel reinforcement head can also prevent cracks form generating around the box body because of the concretion and the shrinkage of the concrete and the structure quality of a cast in place plate can be ensured.

Description

The prefabricated thin-wall box

Technical field

The utility model relates to the filling object on the cast-in-place plate of a kind of building, relates in particular to a kind of prefabricated thin-wall box.

Background technology

In building construction, floor formula superstructure has all adopted the cast-in-place plated construction of cast-in-place shaping basically, the advantage of cast-in-place plated construction is easy construction, efficient height, whole building structural good, but that its shortcoming is a concrete amount is big, cast-in-place plate is overweight, under the situation of large span, need the many columns of design, limited effective utilization in space in the building, the sound insulation value and the heat-proof quality of floor structure are all not good simultaneously, have influence on the commercial value of whole building.For this reason, Chinese patent ZL02233531.5 discloses a kind of reinforced concrete shuttering member, in the enclosed cavity that housing and base plate form hollow cross stiffening rib is set, pre-buried fleece in housing and base plate, and in base plate the embedded bar net.Though this technical scheme preferably resolves the problems referred to above, but because the stiffening rib in its housing is cross structure, Support Level is short, Area of bearing is few, be subjected to the support zone skewness, make the stability and the intensity of shuttering member all be subjected to certain influence, further have influence on the total quality of building.

The utility model content

At the problems referred to above, the purpose of this utility model is to provide the prefabricated thin-wall that a kind of structure is more firm, intensity is higher box.

For achieving the above object, the technical solution of the utility model is to have adopted a kind of prefabricated thin-wall box, the main body of this prefabricated thin-wall box is a rectangular box, be shaped on fibrous mesh cloth in the wall of box body and top, the base plate in advance, the base plate inherence vertically, laterally at least one direction is shaped on reinforcing bar in advance, be provided with the support wall between top board in the box body and the base plate, described support wall is diagonal angle line style intersection wall.

The thickness of described base plate is not less than 3cm, and at least one end of described reinforcing bar is appeared, and the length of appearing is no less than 2cm.

Described top board inherence vertically, laterally at least one direction is shaped on reinforcing bar in advance.

Owing to adopt diagonal angle line style cross support wall, make the two ends of each sidewall of box body all be subjected to support in the prefabricated thin-wall box, sidewall is difficult for inclination and distortion, and on the mechanics angle, diagonal angle line style cross support is more firm than cross cross support; Thin-walled box for same specification, it is longer than the cross contact wire that intersects wall that the diagonal angle line style is intersected wall and box body top, the contact wire at the end, the suffered Area of bearing in box body top is bigger like this, the supporting part distributes also more evenly rationally, support effect is better, make box body have higher strength and stiffness simultaneously, anti-step on, compressive property is stronger, satisfied the needs of site operation well; In addition, in the thickening base plate of thin-walled box precast reinforced after; the thin-walled box can directly be placed on the template before fluid concrete; cast back forms one with concrete; its thickening base plate can directly leak outside and serve as ceiling usefulness, and simultaneously, the steel bar end that leaks outside and the concrete of cast congeal into after the one; can also prevent to shrink at box body because of concrete setting and produce the crack on every side, guarantees the construction quality of cast-in-place plate.

The specific embodiment

Embodiment 1: as shown in Figure 1 and Figure 2, this embodiment is that a kind of main body is square prefabricated thin-wall box, be shaped on fibrous mesh cloth 5 in advance in the wall 6 of box body and top board 1, the base plate 2, the thickness of base plate is not less than 3cm, the thickness of base plate is 5cm in the present embodiment, longitudinally evenly be shaped on reinforcing bar 4 in advance at interval side by side in the base plate 2, the length of reinforcing bar 4 is consistent with the longitudinal size of base plate, is provided with a partition type between top board in the box body and the base plate and supports wall 3.

Embodiment 2: as shown in Figure 3, Figure 4, the difference of this embodiment and embodiment 1 only is that the support wall 3 that is provided with between top board 1 in the box body and the base plate 2 intersects wall for the diagonal angle line style, and other structure is identical with embodiment 1.

Embodiment 3: as Fig. 5, shown in Figure 6, the difference of this embodiment and embodiment 1 only is that the support wall 3 that is provided with between top board 1 in the box body and the base plate 2 is cross type support wall, and other structure is identical with embodiment 1.

Embodiment 4: as Fig. 7, shown in Figure 8, this embodiment is the improvement of carrying out on the basis of embodiment 2, and it is prefabricated to adopt the lengthening reinforcing bar to carry out in the base plate, and reinforcing bar two is stretched out outside the base plate, the length that reinforcing bar is appeared is no less than 2cm, and the length that reinforcing bar is appeared in the present embodiment is 5cm.

Embodiment 5: as Fig. 9, shown in Figure 10, this embodiment is the improvement of carrying out on the basis of embodiment 4, improvements be base plate laterally also at interval evenly be shaped on reinforcing bar 4 in advance side by side, stretch out outside the base plate equally at reinforcing bar two, and the length that reinforcing bar is appeared is 5cm.

Embodiment 6: as Figure 11, shown in Figure 12, this embodiment is the further improvement on the basis of embodiment 5, in the prefabricated panel reinforcing bar, in the top board 1 of thin-walled box vertically, laterally also precast reinforced 4, all stretch out outside the top board at reinforcing bar two, and the length that reinforcing bar is appeared is 5cm.
