Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described herein are merely for purposes of illustration and explanation, and are not intended to limit the invention.
It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
Fig. 1 to 4 show a combined roof PVC grid strip of the present invention.
As shown in fig. 1, the lattice bar 1 of the combined PVC roof is a combination type, and is divided into a lattice bar top 9 and a lattice bar main body 10, and the cross section of the lattice bar main body 10 is a rectangular hollow structure.
Two sides of the bottom of the lattice strip 1 are provided with alkali-resistant fiber cloth 2, and the lattice strip is fixed on the ground through cement mortar in use. The grid strip 1 is made of PVC material, and the cost is low.
The alkali-resistant fiber cloth 2 is arranged on two sides of the lattice bar main body 10, and the alkali-resistant fiber cloth 2 is fixed by using a base layer for paying off, so that the lattice bar is fixed, the fixing is easy, and the flatness and the concrete thickness are well controlled; the proportion of the cement mortar is 1:3, and the alkali-resistant fiber cloth 2 on two sides of the grid strip is fixed by the cement mortar according to the setting-out of the base layer; grid 1 lifts grid top 9 at the during operation, injects cement mortar into grid main part 10, covers grid top 9, treats that cement mortar dries the back, removes grid top 9, easily ann tears open, reduces the labour input.
The invention relates to a construction process method of a combined roof PVC grid strip, which comprises the following steps: the construction process method of the combined roof PVC lattice bar comprises the following steps:
