Abstract

The utility model discloses a novel quakeproof prefabricated slab which solves the problem that the traditional prefabricated slabs are arranged on the load bearing wall in parallel and are disconnected, thus failing to form a whole and realize leakage proofing and earthquake proofing. The utility model is characterized in that: a steel reinforcement (3) which is pre-stressed through stretch is prearranged in a cement prefabricated slab body (1) provided with a hollow pipe hole (7). This steel reinforcement stretches out from both ends of the prefabricated slab body (1), both sides of which are provided with a convex body (2) and a slab wall groove (10). As the steel reinforcement stretches out from both ends of the prefabricated slab, full-length steel reinforcement arranged inside the groove between the slabs and the steel reinforcements vertically embedded in the load bearing wall are welded together and partially on-site cast, the prefabricated slab has strong quakeproof capacity and leakage proofing function.

Description

The novel earthquake-proof precast plate

One, technical field

The utility model belongs to constructional materials, relates in particular to the antidetonation precast plate 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, pendulum is placed on the load bearing wall side by side, and does not link to each other mutually, relies on body of wall to support purely, can not form integral body, thereby exist antidetonation poor, cracking and cause seepage easily between plate and the plate.And in the 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, makes it and is positioned over the reinforcing bar stitch welding of stretching out the adjacent two prefabricated cement board ends on the same bearing wall together.Set up convex shape and wooden partition groove simultaneously in the both sides of precast plate body, make and form horizontal elongated groove between two precast plates of placed adjacent, and in elongated groove, place 1 to 2 elongated reinforcing bar, pre-buried vertical reinforcing bar on making it and being arranged at body of wall links to each other, to carry out the part cast-in-place in the groove space of direction in length and breadth to whole floor plate then, 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: because can be by stretching out the mutual stitch welding of reinforcing bar together between two precast plates, and elongated reinforcing bar is set in the transverse concave groove between plate and plate, it is linked to each other with pre-buried vertical reinforcing bar on the body of wall, and it is cast-in-place that it is carried out the part, thereby improved the whole shock strength in house greatly, it than integral cast-in-situ save time, save money, convenient and swift, have advantages such as antidetonation leakproof.

Below in conjunction with accompanying drawing the utility model is further described.

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.

Among the figure: 1 precast plate body, 2 convex shapes, 3 reinforcing bars, 4 cast-in-situ concretes, 5 bearing walls, 6 pre-buried vertical reinforcing bars, 7 hollow pipeline holes, horizontal elongated groove between 8 plates, 9 elongated reinforcing bars, 10 wooden partition grooves, longitudinal fluting between 11 plates.

Five, the specific embodiment

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 convex shape 2 and wooden partition groove 10 in the both sides of precast plate body 1.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, and reinforcing bar 3 stitch welding that the plate end is stretched out together.Precast plate body 1 neat lay is after on the body of wall 5, form longitudinal fluting 11 between horizontal elongated groove 8 and plate between the precast plate body 1, in elongated groove 8, place 1 to 2 elongated reinforcing bar 9, and it is welded with pre-buried vertical reinforcing bar 6 on being embedded in body of wall 5 in advance, again longitudinal fluting between horizontal elongated groove 8 between the precast plate and plate 11 is filled cast-in-situ concrete 4, thereby precast plate and bearing wall 5 are combined into one, reach the purpose of antidetonation leakproof.

Claims
