Abstract
Disclosed is a quake-resistant leakage-proof prefabricated cement slab which resolves the problem that the traditional cement slabs parallel arranged on a bearing wall are not mutually connected to form integrally and are not shock-resistant and leakage-proof. The shock-resistant leakage-proof prefabricated cement slab is characterized in that a cement prefabricated slab body (1) with a hollow pipeline hole (7) is internally preliminarily equipped with a reinforcing steel bar (3) which applies prestress by stretching, the two ends of the reinforcement prefabricated slab body (1) extend outwards, and two sides of the prefabricated slab body (1) are provided with leakage-proof tooth blocks (2). As the reinforcing steel bar extending outside the two ends of the prefabricated slab is welded with a reinforcing steel bar (6) embedded and perpendicularly placed to carry out local cast in place while carrying out the utility model, slabs are meshed and sealed by the tooth form, and thereby the shock-resistant leakage-proof prefabricated cement slab has relatively high quake-resistant ability and leakage-proof function.
Description
One, technical field
The utility model belongs to constructional materials, relates in particular to the prefabricated cement board of antidetonation leakproof in a kind of builing industry.
Two, background technology
In China's rural urbanization civil building, all using prefabricated cement board basically at present.Because prefabricated cement board is provided with a plurality of hollow pipelines hole, thereby has advantage in light weight, that sound insulation good, cost is low, quick and easy for installation, particularly the reinforcing bar in the middle of it is stretching and has added prestressing force, so intensity is also big, and is that people accept extensively.But because this prefabricated cement board is strip, be arranged side by side on load bearing wall, and do not link to each other mutually, can not form integral body, thereby exist antidetonation poor, cracking and cause seepage easily between plate and the plate.And in the present large-scale top-grade building thing of city-building, though usually the cast-in-place mode that adopts has and can become whole, strong, the watertight advantage of shock resistance with house beam is interconnected, it must arrive the scene laying, and construction speed is slow, and the reinforcing bar of interior shop is difficult to high-strength prestressing force, and bulk strength is not high; Moreover template also will be laid during construction in no hollow pipeline hole in the middle of the cast-in-place floor, so also has high material consumption, construction cost height, soundproof effect is poor, construction speed is slow shortcoming.
Three, summary of the invention
The purpose of this utility model just provides a kind of prefabricated cement board of leaking of can antidetonation also effectively preventing.
The technical solution of the utility model is: be provided with to be preset with by stretching in the cement pre-fabricated panel body in hollow pipeline hole and add prestressed reinforcing bar, this reinforcing bar stretches out from the two ends of precast plate body, general extension elongation is 5-10 centimetre, vertical reinforcing bar pre-buried on the reinforcing bar that stretch out adjacent two prefabricated cement board ends on making it and being positioned over same bearing wall and the body of wall welds together, and carries out cast-in-place to its part.Also can set up leakproof profile of tooth piece in the both sides of precast plate body simultaneously, make the sealing that interlocks of two prefabricated cement board binding site profiles of tooth of placed adjacent, thereby make body of wall and precast plate form an integral body, reach the purpose of antidetonation leakproof.
The beneficial effects of the utility model are: owing to can be welded to each other that to carry out the part on vertical reinforcing bar pre-buried on the load bearing wall cast-in-place by stretching out reinforcing bar between two precast plates, thereby improved the whole shock strength in house greatly, it than integral cast-in-situ both saved time, saved money, convenient and swift, also have the advantage of integral cast-in-situ; Prefabricated cement board both sides are provided with the profile of tooth piece simultaneously, fasten mutually by the profile of tooth piece between two prefabricated cement boards, thereby effectively prevent seepage.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Local structural representation when Fig. 2 uses for the utility model;
Fig. 3 is the utility model cross-sectional view;
Assembly unit generalized section when Fig. 4 is the making of the utility model profile of tooth piece antiphase.
Among the figure: 1 precast plate body, 2 profile of tooth pieces, 3 reinforcing bars, 4 coagulations, 5 bearing walls, 6 pre-buried vertical reinforcing bars, 7 hollow pipeline holes.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, when implementing the utility model, only need be on the basis that makes traditional prefabricated cement board, will make and add prestressed reinforcing bar 3 in the precast plate body 1 and stretch out two ends and be about 5-10 centimetre.Simultaneously can set up leakproof profile of tooth piece 2 in the both sides of precast plate body 1, the profile of tooth of both sides profile of tooth piece 2 both can same-phase be made, and also can antiphase make, and both can be made as multiple toothly, also can be made as monodentate.When using the utility model, be about to reach when needing the cover plate height when building house wall, the pre-buried vertical reinforcing bar 6 of spacing in bearing wall 5, the two ends with prefabricated cement board are positioned over respectively on the bearing wall 5 then.To be positioned over then on the load bearing wall 5 about two blocks of reinforcing bars 3 that stretch out at precast plate body 1 two ends, weld together with pre-buried vertical reinforcing bar 6 on the bearing wall 5, carry out cast-in-place to the space between bearing wall 5 and the right and left precast plate again, thereby precast plate and bearing wall 5 are combined into one, reach the purpose of providing fortification against earthquakes.If when both sides leakproof profile of tooth piece 2 same-phases are made,, make the 2 mutual interlocks of profile of tooth piece then with two mutual back-offs of prefabricated cement board; If when both sides profile of tooth piece 2 antiphases are made, then it is kept flat and to make the 2 mutual interlocks of profile of tooth piece, and fill coagulation 4, seal antiseep thereby reach between plate and the plate between cog.
