Description

An internal support system for the exterior wall of an old building structure

technical field

The utility model belongs to the technical field of building construction, in particular to an inner support system for the outer wall of an old building structure.

Background technique

In recent years, my country's construction industry has developed rapidly, and there are more and more renovation projects for old houses. The exterior wall shapes of old houses are usually required to be preserved. The traditional way of dealing with the exterior walls of old houses is to demolish and rebuild them, and then re-copy the historical features of the exterior walls of old houses. The disadvantage of this technique is that the historical culture of the exterior walls has been greatly reduced. The construction cost of reconstruction is also relatively high. Although some existing renovation projects also adopt the method of setting up supports to retain the outer wall structure of old houses, most of them are reinforced and supported on the outer side of the outer wall, which not only requires pre-treatment of the foundation, but also takes up an The ground area is large, and construction is inconvenient in some narrow space conditions.

Utility model content

Aiming at the deficiencies in the prior art, the utility model provides an internal support system for the exterior wall of an old house structure, which solves the problems of destroying the history and culture of the exterior wall, construction Inconvenience and other issues.

The utility model realizes above-mentioned technical purpose by following technical means.

An internal support system for the exterior wall of an old house structure, including steel columns fixedly installed inside the old house structure, between the steel column and the exterior walls, and between the exterior walls at the four corners of the old house through support members and enclosures purlin connection; multiple purlins are installed on the inside and outside of the exterior wall, one end of the support between the steel column and the exterior wall is welded to the steel column, and the other end is connected to the purlin through a connecting plate. Both ends of the support between the walls are connected to the purlin through the connecting plate; the connecting plate, the support and the purlin are all welded.

Further, a plurality of small connection holes for M12 bolts to pass through are opened on the outer wall, and multiple purlins are fixed and installed on the outer wall by M12 bolts to clamp the outer wall.

Further, the steel column adopts a section steel structure, and the support members and purlins adopt channel steel.

Further, the vertical spacing of each purlin on the outer wall is 3m, and they are arranged along the entire length.

The utility model has the following beneficial effects:

The utility model builds a new steel column with high strength and rigidity inside the outer wall, and connects the outer wall and the steel column as a whole through purlins and supports, and at the same time connects the outer walls at the four corners of the old house as a whole, so that the outer wall It can no longer rely on the structure of the old house for stress. When the old house structure is demolished and rebuilt, it can effectively support the outer wall, retain the historical value of the outer wall to the greatest extent, and the overall construction cost is low. Almost all supporting structures are installed Inside the old house, it does not occupy the external environment space, and is suitable for the renovation project of the old house with a narrow external environment.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the utility model is not limited thereto.

As shown in Figures 1 and 2, the internal support system of the old house structure exterior wall described in the utility model includes steel columns 1, support members 2, purlins 3, M12 bolts 4, and connecting plates 5.

As shown in Figures 1 and 2, the steel column 1 adopts a steel structure and is fixedly installed inside the old house structure, between the steel column 1 and the outer walls 6 around the old house, and between the outer walls 6 at the four corners of the old house Both support members 2 are installed. All around the outer walls 6 of the old houses are provided with a plurality of connecting small holes that are convenient for the M12 bolts 4 to pass through.

As shown in Figures 1 and 2, the support members 2 and purlins 3 are all made of channel steel, and there are multiple purlins 3 on the inside and outside of the outer wall 6, and the purlins 3 are all fixed on the outer wall 6 by M12 bolts 4, clamped The outer wall 6, one end of the support member 2 between the steel column 1 and the outer wall 6 is welded and connected to the steel column 1, and the other end is aligned with the purlin 3, and connected to the purlin 3 through the connecting plate 5. The connecting plate 5 and the support 2 and purlin 3 are connected by welding. Both ends of the support member 2 between the outer walls 6 at the four corners of the old house are connected to the purlin 3 as a whole through the connecting plate 5 .
