Embodiment 1

[0027] Embodiment 1, a plastic template with a self-sealing structure.

[0028] like figure 2 As shown, the existing plastic formwork generally includes a panel 5 and a frame 1 arranged around the back of the panel 5. The upper and lower ends of the frame 1 are respectively the upper edge 6 of the template and the lower edge 7 of the template, and the upper edge 6 of the template is away from the panel 5. One side edge, template lower edge 7 is the panel edge of this plastic formwork.

[0029] like image 3 As shown, the plastic formwork with self-sealing structure provided by this embodiment has a structure: on the outer wall of the frame 1, there are several long grooves 8 adjacent to and parallel to the lower edge 7 of the formwork, and these long grooves 8 are arranged In a straight line, and form a discontinuous intermittent arrangement. The length of the long slot 8 is generally set to be 50 mm to 100 mm. When concrete is poured later, under the action of the vertic...

Embodiment 2

[0036] Embodiment 2, a plastic template with a self-sealing structure.

[0037] like Figure 4 As shown, compared with Example 1, the short groove 9 is located below the discontinuous part between the two long grooves covered by it in this embodiment, that is, the distance between the short groove 9 and the lower edge 7 of the template is lower than that of the long groove 8 from the lower edge of the template. The distance along 7 is short, or in other words, the distance between the short groove 9 and the upper edge 6 of the template is farther than the distance between the long groove 8 and the upper edge 6 of the template. Other structures in this embodiment are the same as those in Embodiment 1.

Embodiment 3

[0038] Embodiment 3, a plastic template with a self-sealing structure.

[0039] The difference from Embodiment 1 and Embodiment 2 is that in this embodiment, two short grooves are arranged on the side of the discontinuity at the opposite ends of each two adjacent long grooves, and the two short grooves are respectively located on both sides of the corresponding discontinuity. , that is, the two short grooves are respectively located above and below the discontinuities they cover. Other structures in this embodiment are the same as those in Embodiment 1.

Abstract

The invention provides a plastic formwork with a self-sealing structure and a sealing method for the plastic formwork. A plurality of long grooves are formed in the outer side wall of a side frame ofthe plastic formwork, short grooves for shielding the end butting positions of the long grooves are formed in the sides of the butting positions of every two adjacent long grooves, the length of the short grooves is greater than the minimum spacing between the long grooves which are shielded by the corresponding short grooves. In this way, after plastic formworks are assembled and butt-joined, thelong grooves on the side frames which are attached to each other form sealed cavities correspondingly, and the short grooves form sealed cavities correspondingly. During subsequent pouring of concrete, under the pressure and vibration effect of the concrete, water flows into the sealed cavities from joints of the formworks, the water with which the sealed cavities are filled forms a damming effect, the role of deceleration and hysteresis is played on the water flowing out from the joints of the formworks at high speed, and the speed of water loss is reduced; and floating slurry flows into thesealed cavities and can further play a water-blocking effect, under the dual effects of the conditions, the disadvantage of the rapid water screening effect caused by the plastic hydrophobic is overcome, and the sealing effect is achieved.

Description

technical field [0001] The invention relates to a sealing device for building templates, in particular to a plastic template with a self-sealing structure and a sealing method for the plastic template. Background technique [0002] Building formwork is a necessary construction tool in the construction of modern pouring concrete structures. Traditional building formwork mainly includes wood formwork and steel formwork. The use of wooden formwork, on the one hand, consumes a lot of wood, which is not conducive to environmental protection; on the other hand, its reusability is low. Steel formwork is difficult to manufacture and process, and the cost of use is high; and it is heavy, which is not conducive to transportation and installation. Now the traditional wood formwork and steel formwork are gradually replaced by plastic formwork. Plastic templates are being used more and more widely because of their light weight, simple processing technology, and high degree of reusabil...
