Detailed Description

The present utility model will now be described in more detail with reference to the drawings wherein preferred embodiments of the utility model are shown, it being understood that the utility model described herein may be modified by those skilled in the art while still achieving the advantageous effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.

The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. Advantages and features of the utility model will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

As shown in fig. 1, an embodiment of the present utility model provides an existing building window reconstruction structure, which includes a raw wall blank 1, the raw wall blank 1 has a window, window lintel 2 disposed at the upper and lower sides of the window and two ends of the window in the raw wall blank 1, and reinforcing layers 3 disposed at the left and right sides of the window, and the reinforcing layers 3 are fixed with the raw wall blank 1 by an implantation structure.

The original wall blank can be a brick structure wall or a concrete structure wall, for example, which is obtained after the wall surface is removed. And the original wall blank with a certain width can be properly removed.

The improvement is carried out on the basis of the original wall blank, so that the reinforcement degree is improved, and the size of a window caused by reinforcement can be reduced or avoided.

The window lintel 2 may be newly provided after the original girder (if any) is removed, so as to improve the supporting performance.

The two ends of the window lintel 2 are positioned in the original wall blank 1, so that the window lintel and the original wall blank are well combined together, and the reinforcement performance is integrally improved.

The reinforcing layer 3 is a reinforced concrete reinforcing layer, wherein the concrete is C40 concrete grouting material, and the reinforcing steel bars are HRB400 reinforcing steel bars. By selecting C40 concrete and HRB400 steel bars, stronger reinforcement performance can be obtained under the condition of reduced thickness.

In one embodiment, the reinforced concrete includes at least two layers of longitudinally disposed rebar 32, one layer being adjacent to the wall and the other layer being remote from the wall.

Correspondingly, the longitudinally arranged steel bars 32 can be connected with the transversely arranged steel bars to form a steel bar cage so as to further improve the reinforcing performance.

Further, the steel bars 32 longitudinally arranged in the reinforcing layer penetrate through the window lintel 2 at the upper side and the lower side, and the two ends of the steel bars are arranged in the original wall blank 1.

In one embodiment, the implant structure includes a plurality of implant bars 33 and a plurality of implant blocks 31.

The embedded ribs 33 may be perforated in the raw wall blank 1, and then the embedded ribs 33 are driven into the raw wall blank 1 after glue is applied.

For the implant block 31, grooves 11 are formed in the original wall blank 1 at the left side and the right side of the window, the implant block 31 is arranged in the grooves 11, and after the concrete of the implant block 31 is poured, the combination of the implant block and the original wall blank 1 can be realized.

Preferably, the embedded ribs 33 are fixedly arranged with the steel bars in the embedded block 31 and the steel bars in the reinforcing layer 3.

Further, the implant block 31 is integral with the reinforcement layer 3.

In particular, referring to fig. 2, the rebars 311 of the implant block are combined with the rebars 32 disposed longitudinally in the reinforcing layer 3.

Further, the implant rib 33 is disposed between the two implant blocks 31 on the same side. As in fig. 1, two of the implant bars 33 are exemplarily shown disposed between two of the implant blocks 31. In one example, the spacing L3 of two of the implant bars 33 between two of the implant blocks 31 may be between 300 and 600 mm.

In one embodiment, the implant depth of the implant rib 33 is greater than the implant depth of the implant block 31.
