Description

Technical Field

[0001] The utility model relates to the technical field of building facade reconstruction, in particular to an old building facade reconstruction structure. Background Art

[0002] Building facades are divided into building exterior facades and building interior facades. Generally, building exterior facades include all external protective parts of the building except the roof, and the facades of old residential areas often cause the skin to fall off or crack due to wind and sun, so regular renovation and construction are required. At present, most of the renovations of old building facades are done by directly laying exterior wall decorative panels after repairing the cracks, and the installation structure is required for the installation of exterior wall decorative panels.

[0003] Currently, the renovation structure for old buildings, such as the publication number CN219548479U, provides an old building facade renovation structure, including a wall, a decorative panel, a keel frame and an assembly frame; angle irons are fixedly installed on both sides of the keel frame by self-tapping screws A, and expansion bolts are inserted into the other side of the angle irons; the assembly frame is detachably installed on the keel frame, and a through hole is longitudinally opened through the front end of the assembly frame, and an I-shaped card block is movably installed in the through hole, and a screw hole is opened through the center of the I-shaped card block, and a hexagon socket bolt is movably installed in the through hole, and the hexagon socket bolt passes through the screw hole, so that each group of work can be adjusted. The spacing between the I-shaped card block and the wall can be adjusted to avoid the situation where multiple groups of I-shaped card blocks cannot be on the same horizontal plane due to errors after installation. Each group of I-shaped card blocks can be flexibly fine-tuned to ensure that the I-shaped card blocks can be smoothly inserted into the card slots to avoid the situation where the I-shaped card blocks cannot be inserted into the card slots and cannot be installed. However, due to the limitations of traditional building structure layout and aging of wall materials, the reconstruction structure frame is too heavy and the combined structure is complex, resulting in large overall project installation costs and reconstruction investment, and the actual scope of application for the facades of old buildings is small. Utility Model Content

[0004] The utility model aims to solve at least one technical problem in the background technology and provide a structure for reconstructing the facade of an old building.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a structure for reconstructing the facade of an old building, comprising:

[0006] Main frame;

[0007] A protection plate, arranged on one side of the main frame;

[0008] The main frame includes: a first bracket, a second bracket and a stand;

[0009] The first bracket and the second bracket are arranged opposite to each other;

[0010] The stand is installed on the sides of the first bracket and the second bracket facing each other;

[0011] The protection plate is located between the first bracket and the second bracket, and two side edges of the protection plate are spaced and fixedly arranged with respect to the two upright frames respectively;

[0012] Positioning studs are provided at two ends of the stand frame on a side away from the protection plate.

[0013] According to one aspect of the utility model, positioning grooves are provided on surfaces of the first bracket and the second bracket facing each other, and one side of the stand is respectively installed in the positioning grooves on the first bracket and the second bracket.

[0014] According to one aspect of the utility model, it also includes: an inner lining plate, the inner lining plate is inserted into the interval gap between the protection plate and the stand;

[0015] The inner lining plate is made of a non-magnetic composite material.

A pad is provided on the side of the stand away from the positioning groove, and the pad is connected to the inner lining plate through a column head. With such an arrangement, the inner lining plate can be used as a filling material to fill the empty slot formed between the main frame and the protection plate, so as to select the inner lining plate material and its function according to the actual reconstruction needs. On this basis, the inner lining plate can be selected as a non-magnetic composite material to provide a flame retardant function while ensuring the overall low weight of the plate, and the pad is used as a connecting structure between the inner lining plate and the stand, and a flame retardant function is provided on the premise that an empty slot is left between the stand, the main frame and the protection plate.

[0027] According to one solution of the utility model, a filling pad is provided between the stand and the side wall of the positioning groove. In this way, the filling pad can strengthen the tightness of the connection structure between the main frame and the stand, and at the same time, the pad material characteristics can provide a silent function for the structure, reducing the noise generated by friction between the structures.

With such arrangement, the annular groove of the cable column core can be exposed, so that the cable column core can be inserted between the diagonally distributed positioning column bolts by adding cables, and the exposed annular groove part of the cable column core is used as a cable sleeve structure. According to the modification requirements, the adjacent main frame structures can be combined and connected by inserting cables, thereby improving the installation strength of the structure.

[0029] According to one solution of the utility model, a compression spring is sleeved on the connection end between the bolt head and the cable column core. With such a configuration, the positioning column bolt can use the bolt head as the insertion end, and the insertion end can provide force buffering between the bolt head and the cable column core through the compression spring extending inward, thereby improving the reliability of the connection structure of the connection end of the modified structure.

[0030] According to the scheme of the utility model, the renovation structure of the utility model utilizes an assembled main frame, a protective plate and a vertical frame to form a structural main body, and its protective plate serves as a protective plate surface of the facade. The material of the protective plate can be selected according to actual renovation needs. On this basis, the renovation structure is specifically inserted into the facade of the building by means of anchor bolts, and its positioning column bolts serve as the insertion ends of the anchor bolts. The renovation structure is prefabricated and formed as an integral part of the factory. During installation and renovation, the facade is installed and laid by flat stacking, which is convenient to install. At the same time, the overall structure has a large amount of surplus space through the combination of the main frame and the protective plate. On the basis of ensuring the protection strength and reliability of the structure, the overall weight of the structure is reduced, and the economy and applicability of the structure are improved.
