Abstract
The utility model relates to a prestressed concrete thin slab for laminated slabs. On the basis of the original prestressed concrete thin slab, the utility model is additionally provided with surface impressing lines and a combined groove (5). The utility model adopts large width dimensions out of the industrial standard to be additionally provided with girder ribs (2) for hanging and hanging hooks (3) so that the new concrete and the utility model have sealed and firm combination, therefore the utility model has the advantages of floor joint reduction, convenient and safe hanging and building quality enhancement.
Description
The utility model relates to constructional materials, particularly a kind of superimposed sheet prestressed concrete thin plate.
At present, in the construction work, the floor structure of building partly adopts the prestressed concrete overlapped slab structure.Promptly earlier prefabricated prestressed concrete thin plate is installed on the strong point of building flooring, at this required steel mesh reinforcement of laying above plate, form prestressed concrete overlapped slab behind the cast-in-place layer concrete, there is following deficiency in wherein used prestressed concrete thin plate: the one, and this two long limits of thin plate face is smoother, and do not have engagement groove, it is not firm that newly placed concrete is combined with two inclined-planes; The 2nd, plate face width degree is little, causes the storied building top surface piece many; The 3rd, because of no girder rib and suspension hook in the plate, make the lifting difficulty, be prone to the damage that fractures, cause unsafe factor.According to the deficiency that pre existing prestressed concrete thin plate exists, the inventor has carried out bold improvement, innovation and creation a kind of new-type superimposed sheet prestressed concrete thin plate.
The purpose of this utility model provides a kind of the combination with cast-in-situ concrete firmly, and plate face width degree is big, reduces the flooring piece, lifts convenient and safe superimposed sheet prestressed concrete thin plate.
For achieving the above object, the technical solution of the utility model is that the concreting by steel mesh reinforcement and steel mesh reinforcement periphery forms, of the present utility model being characterised in that, rectangular prestressed concrete thin plate two long limits are the inclined-plane, two chamfered surfaces have the impression line, the middle district on two inclined-planes is provided with groove along its length, on the steel mesh reinforcement length direction, be installed with steel mesh reinforcement with wide two lifting girder ribs, each fixes two suspension hooks above the girder rib.
That the shape of described groove comprises is square, semicircle or triangle.
The isosceles triangle that described girder rib is made up of 3 φ, 12 to φ 16mm reinforcing bars, leg-of-mutton three limit φ, 6 to φ 10mm reinforcing bars even form admittedly.
The width a=1500 to 3900mm of described prestressed concrete thin plate.
After implementing above technical scheme, because the utility model sets up impression line and groove on two bonding surfaces, the bonding surface that makes superimposed sheet is secure seal more, has improved the building ground quality.Owing to set up girder rib and suspension hook, not only improved plate face intensity again, and made convenient, the safety of lifting.
Below in conjunction with accompanying drawing in detail the utility model embodiment is described in detail.
Fig. 1 is the front view of the utility model superimposed sheet with the prestressed concrete thin plate.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional drawing of Fig. 1.
As Figure 1-3, embodiment of the present utility model is built by the concrete 4 of rectangular steel mesh reinforcement 1 and steel mesh reinforcement periphery to form.Two long limit faces are the inclined-plane, have impression line and groove 5 on two inclined-planes, the steel mesh reinforcement length direction be installed with steel mesh reinforcement with two wide lifting girder ribs 2, each fixes two suspension hooks 3. above the girder rib
That the shape of above-mentioned groove 5 comprises is square, semicircle or triangle.
The isosceles triangle that above-mentioned girder rib 2 is made up of 3 φ, 12 to φ 16mm reinforcing bars, leg-of-mutton three limits are even formed admittedly by φ 6 to φ 10mm reinforcing bars.
The superimposed sheet described in the utility model wide a=1500 to 3900mm of prestressed concrete thin plate.
Claims (4)
1, superimposed sheet prestressed concrete thin plate, it is to be built by the concrete (4) of rectangular steel mesh reinforcement (1) and steel mesh reinforcement periphery to form, of the present utility model being characterised in that, superimposed sheet is the inclined-plane with prestressed concrete thin plate two long limit faces, have the impression line on two inclined-planes, the middle district on two inclined-planes is provided with groove (5) along its length, be installed with on the steel mesh reinforcement length direction with steel mesh reinforcement with wide two lifting girder ribs (2), each fixes two suspension hooks (3) above the girder rib.
2, according to the described superimposed sheet of claim 1 prestressed concrete thin plate, that the shape that it is characterized in that groove (5) comprises is square, semicircle or triangle.
3, according to the described superimposed sheet of claim 1 prestressed concrete thin plate, it is characterized in that the isosceles triangle that each girder rib (2) is made up of 3 φ, 12 to φ 16mm reinforcing bars, leg-of-mutton three limits are even formed admittedly by φ 6 to φ 10mm reinforcing bars, and apex is suspension hook (3) fixedly.
4, according to the described superimposed sheet of arbitrary claim prestressed concrete thin plate in the claim 1 to 3, it is characterized in that width a=1500 to 3900mm.
