Description

Building concrete slab dividing strip

Technical Field

The utility model belongs to the technical field of curbstone clamps, and particularly relates to a building concrete slab separation strip which prevents cracking and water blocking and water seepage caused by thermal expansion and contraction of building concrete slabs, and is suitable for pavement, roofing, water dispersion and large-area coagulation.

Background

After the concrete slab is poured, irregular cracking is easy to form due to expansion caused by heat and contraction caused by cold, the stress of the structure is influenced, water seepage is caused, and the service life is influenced.

The most common construction modes at present are as follows: the plate is cut after being formed, and the defects of insufficient cutting depth, untimely cutting, dust noise pollution, low efficiency and the like exist.

At present, some extruded sheets are used for separation, but the extruded sheets are removed in the later stage and are embedded and fixed by sealing paste, so that the construction is troublesome, the construction is difficult to straighten after the completion, the labor and the materials are wasted, and the construction efficiency is low.

Disclosure of Invention

The utility model provides a separation strip for building concrete blocks, which can solve the problems pointed out in the background art

The utility model provides a building concrete slab divides board parting bead, includes the parting bead body main part, parting bead body main part lower extreme has the stiff end, the both sides of parting bead body main part all are equipped with the anchor end, be equipped with the flexible body in the parting bead body main part, make parting bead body main part can stretch out and draw back to both sides.

Preferably, the separation strip body comprises L-shaped attaching plates at two sides, the lower end of the L-shaped attaching plates is a fixed end, a fixing hole is formed in the fixed end, and a telescopic body is connected between the attaching plates at two sides.

Preferably, the telescopic body is a rubber body.

The beneficial effects are that: the utility model provides a building concrete slab partition strip which has the advantages of simple structure, convenient installation, high installation efficiency, one-time forming, no need of secondary treatment, cracking resistance, high water resistance, convenient construction, smoothness, beautiful appearance and the like.

Detailed Description

One embodiment of the present utility model will be described in detail below with reference to the attached drawings, but it should be understood that the scope of the present utility model is not limited by the embodiment.

Example 1:

as shown in fig. 1-2, the partition strip for building concrete slab blocks provided by the embodiment of the utility model comprises a partition strip body, wherein the lower end of the partition strip body is provided with a fixed end 11, both sides of the partition strip body are respectively provided with an anchoring end 2, and the partition strip body is provided with a telescopic body 12, so that the partition strip body can be telescopic to both sides.

Specifically, the separation strip body main part includes L shape laminating board 13 of both sides, and the lower extreme of L shape laminating board 13 is stiff end 11, is equipped with fixed orifices 14 on the stiff end 11, connects flexible body 12 between the laminating board 13 of both sides, and L shape laminating board 13 and anchor end 2 can be the plastics material, like the PVC material, and anchor end 2 can be the anchor piece, plays the effect of being connected with concrete anchor and the effect of blocking water, both integrated into one piece, and flexible body 12 is the rubber body, and its both sides are connected L shape laminating board 13 through the bonding glue respectively.

The working principle or the construction method of the utility model comprises the following steps: before concrete pouring, fixing holes 14 of the L-shaped laminated plates 13 are fixed on a concrete slab template or a base layer by iron nails, self-tapping or mortar, the specification of the separation strip is selected according to the thickness of the concrete, the upper plane and the upper surface of the concrete are ensured to be at the same height when the separation strip is fixed,

the separation strip is inlaid in the concrete after the concrete is poured and is tightly combined with the concrete, when the concrete expands due to heat and contracts due to cold or other factors are stressed and stretches, the damage and cracking of the concrete slab are effectively slowed down by utilizing the stretching and extrusion resistance of rubber, and the rubber body is kept complete and can play a role in water resistance and permeability resistance.

The L-shaped attaching plates 13 on two sides of the separation strip are required to have certain bending resistance and torsion resistance, can bear certain external force and not deform, so that smoothness and attractiveness are ensured, and procedures of secondary construction cutting and embedding sealing paste are not required after finishing plastering of the concrete slab.

The foregoing disclosure is merely illustrative of some embodiments of the utility model, but the embodiments are not limited thereto and variations within the scope of the utility model will be apparent to those skilled in the art.
