Background

At present, partial monomers of the archaize building reconstruction project need to be reinforced to the original brick-concrete wall body due to reconstruction construction. Most of the reconstruction buildings are residential buildings, and are all of brick-wood structures and through-bucket type wood frameworks. The gable is built by green brick walls, the lower part of the wall is built by local kiln bricks, but the kiln bricks are generally smaller and different in specification, and the upper part of the wall is built by green brick empty hoppers. Therefore, structural uncertainty of the old wall body of the house increases construction difficulty for reinforcing the later-stage wall body. At present, the conventional masonry reinforcement method cannot be implemented in a reference manner. For example, the reinforced concrete structure is reinforced, and although the reinforcing effect on the original wall body is good, the original wall body is damaged greatly, so that the appearance of the wall body can not be preserved.

Description of the embodiments

The features of the utility model and other related features are described in further detail below by way of example in conjunction with the following figures to facilitate understanding by those skilled in the art:

as shown in fig. 1-3, the labels 1-8 are shown as: the wall comprises an inner wall body 1, an outer wall body 2, channel steel 3, square tubes 4, anchor bolt base plates 5, opposite-pulling anchor bolts 6, square tubes 7 and square tubes 8.

Examples: as shown in fig. 1 to 3, the reinforcement structure of the existing wall in this embodiment is used for in-situ reinforcement of the existing gable. When the existing gable is built, the gable generally comprises an inner wall body 1 and an outer wall body 2, and a certain gap is reserved between the inner wall body 1 and the outer wall body for ventilation or walking. The reinforcement structure in this embodiment may be used to reinforce one of the inner wall 1 or the outer wall 2, and in some cases, the inner wall 1 and the outer wall 2 may also be reinforced simultaneously, so as to ensure the structural stability of the existing inner wall 1 and outer wall 2.

Referring to fig. 1 and 2, the present embodiment is described with respect to reinforcing an inner wall 1.

Specifically, the reinforcing structure in this embodiment includes a door-shaped bracket disposed between the inner wall 1 and the outer wall 2, and the door-shaped bracket belongs to a hidden project for two conventional outer vertical surfaces, i.e., the inner side of the inner wall 1 and the outer side of the outer wall 2, so that the original style of the ancient building or the archaized building can be ensured.

The door-shaped bracket comprises a plurality of square steels 8 which are arranged along the trend of the wall surface of the inner wall body 1, wherein the square steels 8 are arranged at a certain interval in a landing way, so that the upright post of the door-shaped bracket is formed. The top ends of a plurality of square steels 8 are connected through a square pipe 7 which is welded and transversely arranged to form an integral structure, and the square pipe 7 is used as a cross beam of a door-shaped bracket. A horizontal member is provided at one side of the square tube 7 adjacent to the inner wall 1, and the horizontal member includes a plurality of square tubes 4 extending toward the inner wall 1 and diagonal rods or diagonal bars for forming the horizontal member into a truss structure, so as to improve the structural strength and stability of the horizontal member.

A channel steel 3 is provided on one side of the horizontal member adjacent to the inner wall 1, and the channel steel 3 may be a "]" shaped steel having two insertion portions which are inserted into the brick joints of the inner wall 1 at the upper and lower positions in the height direction so that the steel 3 is inserted into the inner wall 1. In this embodiment, in order to avoid poor reinforcement effect caused by too wide reinforcement width, as shown in fig. 2, two channel steels 3 are arranged along the height direction of the inner wall 1, and the two channel steels 3 are respectively inserted into the upper and lower portions of the inner wall 1.

An anchor bolt base plate 5 is arranged on the inner side surface of the inner wall body 1 and at a position corresponding to the channel steel 3, and anchor bolt holes matched with the opposite-pulling anchor bolts 6 are reserved on the anchor bolt base plate 5 as shown in fig. 3; the anchor bolt backing plate 5 positioned on the inner side of the inner wall body 1 and the channel steel 3 positioned on the outer side of the inner wall body 1 can be connected and fixed to form an integral structure by screwing the opposite-pulling anchor bolts 6 into the anchor bolt holes. In this way, the embedded channel steel 3 and the anchor bolt backing plate 5 which is opposite to the embedded channel steel are arranged at the breadth position of the inner wall body 1, and the channel steel 3 is effectively supported by the door-type bracket through the truss-type horizontal member, so that the structural strength of the inner wall body 1 is effectively enhanced.

The embodiment comprises the following steps when in construction:

1) Judging whether the temporary support is necessary for the existing wall to be reinforced or not according to the current situation evaluation condition of the existing wall, if so, temporarily supporting the wall to be reinforced so as to further ensure the structural stability of the wall in situ reinforcement.

2) And the steel structure is the foundation of the portal bracket to ensure the structural strength and the stress performance of the portal bracket.

3) The steel structure supports the main body construction, namely, the door-shaped bracket, the channel steel 3, the anchor bolt backing plate 5 and the like. When the channel steel 3 is applied, the adhesive such as mortar between brick joints can be removed first, so that the channel steel 3 can be embedded into a wall body.

4) If the temporary support exists, the temporary support is removed after the construction of the steel structure support is completed and the structure is checked and accepted.

The embodiment is implemented in specific manner: when the outer wall body 2 needs to be reinforced, the door-shaped bracket shown in fig. 2 can be rotated to enable the horizontal component to face the outer wall body 2, and the corresponding components such as channel steel 3, anchor bolt base plates 5 and the like are applied to the outer wall body 2. If the inner wall 1 and the outer wall 2 need to be reinforced at the same time, the structure of the door-shaped bracket can be changed to a certain extent, even if horizontal members with enough strength are arranged on two sides of the square tube 7 serving as a cross beam, and then members such as channel steel 3, anchor bolt backing plates 5 and the like are respectively arranged at the outer ends of the horizontal members on two sides so as to reinforce the inner wall 1 and the outer wall 2 at the same time.

The width of the channel steel 3 is matched with the width of the brick joint in a certain range on the existing wall body, namely, according to the reinforcing range of the wall body, the brick joint at the uppermost part and the brick joint at the lowermost part of the reinforcing range determine the width of the channel steel 3, so that the channel steel 3 can be accurately embedded into the reinforcing range of the existing wall body.

Although the foregoing embodiments have been described in some detail with reference to the accompanying drawings, it will be appreciated by those skilled in the art that various modifications and changes may be made thereto without departing from the scope of the utility model as defined in the appended claims, and thus are not repeated herein.
