Description

Precasting floor composite set

Technical field

The utility model relates to a kind of precasting floor composite set, especially refers to a kind of continuous length that reaches the increase bar splicing, and can strengthen the device of the intensity of two precasting floors after combination.

Background technology

Present reduction and convenience for the building operations time, pre-casting method has become one of building construction method that widely uses, because pre-casting method is that beam, post and the floor that prior precasting is good directly is transported to assembled on site, grouted solid gets final product, therefore the site operation activity duration can significantly be saved, in the place that the floor level is had relatively high expectations, also can utilize the level of precasting floor to require to reach the problem of the horizontal accuracy deficiency of the floor of avoiding site operation in advance.

As shown in Figure 5, tradition precasting floor is when applying, mostly be two precasting floors 70,80 to be bridged be placed on the i beam 60, again with space, interval 90 concrete perfusions of 70,80 on two precasting floors to make the beam body of building, conventional practice is the binding reinforcing bar 71,81 that is protruded out by each precasting floor 70,80 side in 90 places, space, aforesaid interval, lay several overlap joint reinforcing bars 91 that interweave with reinforcing bar when connecting in these 90 places, space, interval, its shortcoming is:

Overlap joint reinforcing bar 91 and the overlap distance that links between the reinforcing bar 71,81 are too short, can cause behind fluid concrete, produce the problem of strength deficiency, in order to prevent this kind strength deficiency problem, more reinforcing bar must to be set reducing the demand of lap length, but or the width that increases beam to increase lap length, these two kinds of methods can bring inconvenience to the construction of building-site and the manufacturing of precasting member, and the high shortcoming of cost is also arranged, necessity of being improved is arranged in fact.

Summary of the invention

Main purpose of the present utility model is to overcome the deficiencies in the prior art and defective, and it is purpose that a kind of continuous length that reaches the increase bar splicing is provided, and can reach the intensity of reinforcement two precasting floors after combination.

For reaching above-mentioned purpose, the utility model takes following technological means to be reached, and wherein includes in the utility model:

Both sides are provided with a precasting floor respectively on i beam, has space at interval between two relative precasting floors, relative precasting floor place is provided with a groove respectively, the opposite position of each precasting floor is respectively equipped with several relative binding reinforcing bars, the binding reinforcing bar on upper strata is protruded out by groove, the overlap joint reinforcing bar is set in the job site between the binding reinforcing bar on the upper strata that protrudes out relatively, so that fluid concrete, the utility model can reach the continuous length that increases bar splicing, and can strengthen the intensity of two precasting floors after combination.

Secondary objective of the present utility model is that the height of the groove on the precasting floor is less than 1/2 height of precasting floor.

The specific embodiment

Please referring to shown in Fig. 1,2, precasting floor composite set of the present utility model includes:

I beam 10 (also can be a beam), the place, both sides is provided with a precasting floor 20,30 respectively on i beam 10, has proper spacing space 40 therebetween;

By each precasting floor 20,30 place several relative binding reinforcing bars 21,22,23 and 31,32,33 are set towards space, interval 40 respectively;

Design features of the present utility model is: relative precasting floor 20,30 places are provided with a groove 24,34 respectively, the height of each groove 24,34 is less than 1/2 height of each precasting floor 20,30, each groove 24,34 has the aspect at right angle 241,341 respectively in the inboard, wherein the binding reinforcing bar 23,33 on each upper strata is laterally protruded out by each groove 24,34 place respectively.

When construction, the binding reinforcing bar 23,33 on upper strata is sentenced overlap joint reinforcing bar 50 overlap joints relatively, so that cast-in-place concrete, because the groove 24,34 that the utility model contracts in being provided with respectively at the opposite side of each precasting floor 20,30, so that the binding reinforcing bar on upper strata 23,33 protrudes out long overlap distance, so that overlap mutually with overlap joint reinforcing bar 50 respectively, the utility model can reach the continuous length purpose that increases bar splicing, and can strengthen the intensity of two precasting floors 20,30 after combination.

As shown in Fig. 3,4, major part is same as the structure in the earlier figures 1,2, its difference be in: relative precasting floor 20,30 places are provided with a groove 24,34 respectively, and each groove 24,34 has a hypotenuse 242,342 respectively in the inboard, equally, also can reach identical aforesaid purpose.

Therefore, the utility model is with under the simple space structures kenel, opposite position in each precasting floor 20,30 is respectively equipped with groove 24,34, to increase the binding reinforcing bar 23,33 on upper strata, the upper strata that is protruded out by each precasting floor 20,30 side links the overlap distance of reinforcing bar 23,33, so that with the usefulness of overlap joint reinforcing bar 50 overlap joints, can reach the continuous length that increases bar splicing, and can strengthen the intensity of two precasting floors 20,30 after making up.
