Description
Technical Field
The utility model relates to a prefabricated wallboard technical field especially indicates a peripheral dado of prefabricated lightweight concrete.
Background
Precast concrete surrounding panels are one of the most widely used types of components in fabricated concrete construction. In a traditional cast-in-place concrete shear wall structure, except for a load-bearing shear wall, other enclosure walls are usually built by aerated concrete blocks, and a frame beam is a cast-in-place reinforced concrete beam. The most applied form in the peripheral retaining wall of precast concrete at present is that, the roof beam adopts the coincide roof beam (partly prefabricated, partly cast-in-place), and non-bearing wall adopts the concrete prefabrication, has following problem:
1. because the peripheral retaining wall is poured at one time, the concrete label of the non-bearing part wall body is the same as that of the beam concrete, and the cost is increased more;
2. the non-bearing wall adopts the concrete for the beam, and the density is 2.5t/m3And the volume weight of the traditional aerated concrete masonry is 0.75t/m3The weight of the whole building structure is increased, the earthquake resistance is unfavorable, and the requirements on hoisting and transporting equipment are correspondingly increased;
3. the rigidity of the concrete for the beam is greatly increased compared with that of the aerated concrete building block, and the rigidity is increased to be unfavorable for shock resistance.
SUMMERY OF THE UTILITY MODEL
The utility model provides a peripheral dado of prefabricated lightweight concrete has alleviateed the dead weight, and it is favorable to building whole antidetonation, practices thrift the hoist and mount cost.
The technical scheme of the utility model is realized like this: the utility model provides a peripheral dado of prefabricated lightweight concrete, includes the precast beam and sets up in the light precast wall of precast beam lower extreme, and the department of meeting of precast beam and light precast wall separates through the wire net piece, and pre-buried in the precast beam has the roof beam steel reinforcement cage, and pre-buried in the light precast wall has wall reinforcing bar rack, and in the roof beam steel reinforcement cage was inserted to the upper end of wall reinforcing bar rack, the wire net piece was along vertically setting up in the position department that the wall reinforcing bar rack is close to the roof beam steel reinforcement cage.
Furthermore, a plurality of reserved nuts are pre-embedded at two ends of the light prefabricated wall, a plurality of pre-embedded joint bars and round head hanging nails are arranged on the upper side of the prefabricated beam, and threaded blind holes corresponding to the pre-embedded joint bars in a one-to-one mode are arranged on the lower side of the light prefabricated wall.
Furthermore, beam bottom stress longitudinal bars are arranged in the beam reinforcement cages on two sides of the upper end of the wall reinforcement net rack.
And furthermore, reserved template opposite-pulling holes are formed in the light prefabricated wall and the prefabricated beam on the inner side of the reserved nut.
The utility model has the advantages that:
the utility model discloses alleviateed the dead weight, it is favourable to the whole antidetonation of building, also can reduce the requirement to building site hoisting equipment simultaneously, can practice thrift the hoist and mount cost, material self cost also keeps level with ordinary concrete basically, has great using value.
