Description

Floor cracking-prevention joint splicing structure

Technical Field

The utility model relates to an assembly type structure, concretely relates to floor prevents ftractureing piece structure.

Background

In the traditional construction, the floor construction is to form the integral floor by in-situ pouring after a formwork is erected by an in-situ formwork, the occupied labor and materials for the construction are more, and the construction site is chaotic.

Chinese patent CN 20716945 discloses a wallboard anti-cracking joint structure, it sets up the indent respectively through the junction of assembling the wallboard at two, packs flexible anti-crack mortar layer in the indent, lays alkali-resisting net check cloth in the flexible anti-crack mortar layer, and the outside on flexible anti-crack mortar layer sets up flexible putty layer, also sets up alkali-resisting net check cloth in the flexible putty layer to effectively reduce the fracture phenomenon of wallboard handing-over position, guarantee that the level and smooth and pleasing to the eye of joint department. However, the structure is only suitable for treating the joints of the wall plates and is not suitable for treating the joints of the floor plates which need to bear vertical loads.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that, it is not enough to overcome prior art, provides an effectively reduce floor handing-over position fracture phenomenon, guarantees that piece department levels and pleasing to the eye floor prevents ftractureing piece structure.

For solving the technical problem, the utility model provides a piece structure that ftractures is prevented to floor, first floor and second floor including mutual concatenation, first floor orientation one side of second floor is equipped with first mat surface, the second floor orientation one side of first floor is equipped with the second mat surface, forms between first mat surface and the second mat surface to have an open-ended piece, the piece intussuseption is filled with flexible anti-crack mortar, the opening outside of piece and with the first floor of opening homonymy and the concatenation end outside of second floor are equipped with flexible anti-crack mortar layer, and flexible anti-crack mortar in situ is equipped with net cloth. Furthermore, the cross section of the splicing seam is triangular.

Further, the cross sections of the first rough surface and the second rough surface are both stepped.

Further, the flexible anti-crack mortar layer extends to two sides of the abutted seam by at least 100 mm.

Further, the grid cloth is evenly distributed in the flexible anti-crack mortar layer, and the width of the grid cloth is larger than or equal to 200 mm.

Further, the mesh cloth is alkali-resistant mesh cloth.

The utility model discloses do the triangle form piece processing to precast floor and precast floor, and pack the flexible anti-crack mortar in the piece, the outside of the flexible anti-crack mortar and the concatenation end outside of first, two floors are equipped with flexible anti-crack mortar layer, and the flexible anti-crack mortar in situ is equipped with net cloth, makes the piece construction effect between the floor better, and construction process is simple swift, and is economical reasonable.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. casting a floor slab in situ; 2. flexible anti-crack mortar; 3. mesh cloth; 4. a flexible anti-crack mortar layer; 5. a first rough surface; 6. a second rough surface; 7. a first floor slab; 8. and a second floor.

Detailed Description

The invention is further described below with reference to specific preferred embodiments, without thereby limiting the scope of protection of the invention.

For convenience of description, the relative positional relationship of the components, such as: the descriptions of the upper, lower, left, right, etc. are described with reference to the layout directions of the drawings in the specification, and do not limit the structure of the present patent.

Example 1:

as shown in fig. 1, the utility model discloses a piece structure embodiment is prevented ftractureing by floor includes first floor 7 and the second floor 8 of mutual concatenation, it is first, be equipped with the first mat surface 5 of leanin on the first floor 7 of second floor concatenation department, be equipped with the second mat surface 6 of leanin on the second floor 8, it is first,

second floor

7, 8 concatenation backs, it is first, two mat surfaces 5, form between 6 and have opening and cross section for the piece of three horn shapes, pack flexible anti crack mortar 2 in the piece, the open-ended outside reaches the first floor 7 of opening homonymy and the concatenation end outside of second floor 8 are equipped with flexible anti crack mortar layer 4, be equipped with net cloth 3 in the flexible anti crack mortar layer 4. The flexible anti-crack mortar layer extends for at least 100mm to the outside of the first floor plate 7 and the second floor plate 8 at two sides of the abutted seam. The gridding cloth 3 is symmetrically distributed in the flexible anti-crack mortar layer 4 in a relatively spliced mode, and the width of the gridding cloth 3 is larger than or equal to 200 mm.

The scrim 3 is preferably an alkali-resistant scrim.

During specific construction, a plurality of first floor plates 7 and a plurality of second floor plates 8 are manufactured according to detailed design drawings, and after the whole floor construction is completed by hoisting the first floor plates 7 and the second floor plates on site through workers, the abutted seams between the first floor plates 7 and the second floor plates 8 are processed. The first rough surface and the second

rough surface

5 and 6 of the abutted seam are cleaned firstly, and the flexible anti-crack mortar 2 is added into the abutted seam. And then coating a flexible anti-crack mortar layer 4 on the outer part of the flexible anti-crack mortar 2 and the outer part of the splicing end of the first floor plate 7 and the second floor plate 8, wherein the coating width from the splicing seam to the first floor plate 7 and the second floor plate 8 on two sides is preferably more than or equal to 100mm, then paving an alkali-resistant mesh cloth 3 with the width of more than or equal to 200mm on the flexible anti-crack mortar layer 4, and finally coating a flexible anti-crack mortar layer 4.

The above description is only for the preferred embodiment of the present application and should not be taken as limiting the present application in any way, and although the present application has been disclosed in the preferred embodiment, it is not intended to limit the present application, and those skilled in the art should understand that they can make various changes and modifications within the technical scope of the present application without departing from the scope of the present application, and therefore all the changes and modifications can be made within the technical scope of the present application.
