Abstract

The utility model discloses a boxed wall pre-cast element. The utility model is formed by pouring the concrete to a mesh reinforcement in a mould. The utility model is provided with a hollow box body which is composed of six pieces of reinforced concrete, and the interior of the box body is provided with at least one reinforced concrete column. The length of the reinforcing bar in a long reinforced concrete plate is larger than the length of the long plate, and the reinforcing bar extends out of both ends of the long plate. If the pre-cast element is used, a large amount of clay and cement used for brick making can be saved, the construction speed can be quickened, and the cost can be reduced. The utility model has firm and stable building, favorable shock resistance, strong heat isolation and heat insulation performances.

Description

Boxed wall pre-cast element

The utility model relates to the design of prefabrication in the builing industry, the design of the prefabrication of particularly nonweight-bearing vertical partition wall body of wall.

Building building at present generally all is to build with a piece solid brick, and under situation about adhering to specification, also useful hollow brick substitutes solid brick.A kind of through-hole type body of wall prefabrication of being made by steel concrete is arranged, and profile is flat cylinder shape, and specification has multiple, if any a kind of specification be 3M length * 0.5M wide * the 0.1M height.In have 5 of row to connect the long through-holes of both ends of the surface, promptly as seen 5 3M Long Circles of horizontal row (as the lotus root hole) or square through hole are arranged from end face.It only has reinforcing bar in the concrete slab of two block length directions.

The purpose of this utility model provides a kind of alternative of solid wall, a kind of hollow box body of wall prefabrication of being made by steel concrete.

The utility model is realized by following technology:

It has the hexahedron steel mesh reinforcement that reinforcing bar is bundled into, the reinforcing bar of its length direction must exceed the length of hexahedron steel mesh reinforcement, make the box prefabrication of the hollow with six armored concrete slabs for the model poured concrete oar of basis by template system thus, be it have steel concrete two block lengths to plate, two are wide high to plate to plate and two.Reinforcing bar length in the steel concrete long slab must be greater than long slab.The reinforcing bar that is it stretches out outside the long slab two ends.Being shaped on for gaining in strength between two steel concrete long slabs is one steel concrete reinforcing prop at least.

With drawings and Examples technical scheme is further described below.

Fig. 1 is the utility model structural representation.

Fig. 2 is the transverse sectional view of Fig. 1.

(1) is reinforcing bar among the figure, and (2) are reinforcing prop.Size dimension of the present utility model designs on demand.As to desire to make 3M * 1M * 0.20M area be 3M ², volume is 0.6M ²Hollow box body of wall prefabrication.Step is as follows:

(1) generally can adopt the reinforcing bar of ∮ 3-4mm, laterally each is long with 10,3.4M, vertical each with 11,1.4M length, the crosspoint between the reinforcing bar fastens with iron wire, makes two steel mesh reinforcements.Respectively prick out one section reinforcing bar (as the reinforcing bar of reinforcing prop) at a, b, c, d and e, f, g, h point, with the model poured concrete slurry of template system, make long as shown in the figure 3M, high 1M, ABCD and EFGH two block length pieces, horizontal and vertical two are all reserved the long steel bar end of 0.20M;

(2) make mould with two long thick bamboo tube sheets of 0.16M, entangle the bar dowel on a, b, c, the d point, poured concrete closes up in opposite directions with another block length plate again, and the bar dowel on e, f, g, the h point is inserted in the relative thick bamboo tube, promptly makes four reinforcing props after doing;

(3) steel bar end that will vertical (short transverse among the figure) is done right angle bending in opposite directions, equally through wooden model, grouting make ABFE and two of DCGH wide to plate, it is high to plate to cast two of ADHE and BCGF again.Length reinforcing bar at two ends in plate is reserved and is not done bending, so its reinforcing bar stretches out outside the long slab two ends.High reinforcing bar in plate adds bundle in addition.

The utility model can laterally use as shown in Figure 1, also can hold up and use.When building frame construction building, collude beam or the rib steel in the post, the poured concrete again of putting framework on the spot with the steel bar end of reserving, produce beam or post, that is to say, this prefabrication can laterally use with post and cooperate, also can vertically use to cooperate, make this prefabrication become as a whole with beam or post with beam.The stackable use of this prefabrication, or vertically use side by side, the seam between the prefabrication is whitewashed with cement, mortar-chalked joint.

The utility model has the advantages that:

(1) hollow degree height. Inside is all the space except some reinforcing props are arranged, in order to substitute solid brick, saved a large amount of clays, compares with existing through-hole type body of wall prefabrication, can save the concrete decades of times. Reduce the house deadweight, be convenient to transportation and construction and installation, can accelerate speed of application, reduced cost.

(2) since this prefabrication with or post become as a whole, so building is firm, intensity is big, and is durable in use, shock resistance is good.

(3) heat-insulation and heat-preservation is good.

Claims

1, a kind of box body of wall prefabrication has by concrete and pours steel mesh reinforcement and the armored concrete slab that makes in model, it is characterized in that:

(1) it has the hollow box body that is made of six armored concrete slabs;

(2) to have be one steel concrete reinforcing prop at least in the inside of casing;

(3) the reinforcing bar length in the steel concrete long slab is greater than long slab length, and reinforcing bar stretches out outside the long slab two ends.
