Description

Technical Field

[0001] The present invention relates to the field of prefabricated building construction, and in particular to an old building reinforcement structure suitable for urban renewal. Background Art

[0002] In my country's towns, counties and some streets in cities, there are a large number of old buildings along the streets. Most of these buildings along the streets are of the same form, generally not high in number, and the front facade is relatively simple. However, due to years of disrepair, the exterior walls of these buildings are incomplete, polluted and damaged, and the appearance of the buildings is messy, which seriously affects the appearance of the building facades, and some even have structural safety hazards.

[0003] In order to improve the overall appearance and quality of urban buildings, "urban renewal" is an important means of building a modern city. For example, according to the plan, a certain area needs to be built into a commercial street with a specific style. At this time, the old buildings facing the street need to be planned. There are usually two ways to achieve this: one is to demolish and rebuild all the original old buildings, but this method involves land acquisition, compensation and resettlement of residents, demolition, new construction, etc., which will consume a lot of manpower, material resources and financial resources; the other is to renovate the original old buildings, and the current construction method of traditional facade renovation is:

[0004] 1. First, remove the relevant base materials on the walls of the original old buildings;

[0005] 2. New keels and load-bearing structure layers are built, and the structural force is based on the original building;

[0006] 3. New decorative materials are added, cut, welded, and processed on site, and the decorative materials are laid along the entire wall of the old building and fixed to the keel.

[0007] Although this renovation method can play a certain role in decorating and reinforcing old buildings, its effect is very limited and can only play a certain role in reinforcing cracks and falling off of the exterior walls. However, it is still far from enough to strengthen the overall structure of the building. At the same time, this method has a long construction period, a complex construction process, and high pollution, and has a great impact on business operations and residents. Summary of the invention

[0008] The present invention aims to provide an old building reinforcement structure suitable for urban renewal, so as to achieve structural reinforcement of old buildings.

[0009] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a reinforcement structure for old buildings suitable for urban renewal, comprising a decorative support body arranged on the outer side of the old building, wherein a reinforcing longitudinal beam is detachably connected between the decorative support body and the old building; the decorative support body comprises a plurality of column bases and supporting steel columns detachably connected to the column bases, and reinforcing cross beams are detachably connected between adjacent supporting steel columns; the column base comprises a base plate, wherein at least two connecting steel parts for fixing to the ground are arranged on the base plate, and an installation base for installing the supporting steel columns is also arranged on the base plate, and the installation base comprises a connecting plate connected to the base plate and a connector fixedly installed on the connecting plate.

[0010] The principles and advantages of this solution are:

[0011] 1. By independently setting up a decorative support body on the outer side of the old building, and then connecting the decorative support body and the old building body through a reinforced longitudinal beam, the decorative support body can play a reinforcing role on the old building structure. In addition, by connecting each supporting steel column into one through a reinforced cross beam, the connection stability of the entire decorative support body is enhanced, thereby ensuring the reinforcement effect on the old building body.

[0012] 2. In this scheme, the load-bearing part of the decorative support body is the column base, which is achieved by drilling pile holes on the ground, pouring concrete into the pile holes and inserting the connecting steel parts of the column base into the concrete in the pile holes. After the concrete reaches the designed strength, the column base is firmly installed on the ground. In this way, the supporting force of the entire decorative support body is transmitted to the ground through the column base, ensuring the supporting force of the decorative support body.

[0013] 3. In this scheme, all components are prefabricated in advance, and all components are assembled and installed through detachable connections. Therefore, there is no need to cut or weld materials on site. The construction process is simple and the assembly speed is fast with a short cycle. At the same time, there will be no construction pollution problems such as high noise and large dust during the construction process, so it will not affect the normal business and life of merchants and residents.

[0014] 4. The independently set decorative support can be freed from the original building shape, style and other restrictions, and a new architectural style can be redesigned according to new functional and aesthetic requirements, such as antique buildings. This provides a wider design space for later architectural styles.

[0015] Preferably, as an improvement, the mounting base and the base plate are provided with a position adjustment portion, the position adjustment portion comprises adjustment strip holes respectively provided on the connecting plate and the base plate, and a locking piece is provided in the adjustment strip hole.

[0016] Preferably, as an improvement, an auxiliary strip hole is provided on the substrate, and the auxiliary strip hole is located on the extension line of the adjustment strip hole.

[0017] Preferably, as an improvement, the connector comprises a square structure formed by connecting at least three steel plates, the steel plates are provided with connecting holes for connecting with steel columns, and each steel plate is fixedly connected with a reinforcing plate.

[0018] Preferably, as an improvement, it also includes a mounting plate detachably connected to the old building body, and the mounting plate and the supporting steel columns are respectively detachably connected with groove-shaped connectors for installing reinforced longitudinal beams.

[0019] Preferably, as an improvement, a decorative protective cover is provided on the peripheral wall of the substrate.

[0020] Preferably, as an improvement, the spacing between adjacent supporting steel columns matches the spacing between structural columns of the old building.

[0021] Preferably, as an improvement, the decorative support body is provided with decorative eaves at each floor corresponding to the old building. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is further described in detail through specific implementation methods:

[0029] The figure marks in the drawings of the specification include: base plate 1, connecting steel part 2, connecting plate 3, connecting body 4, second adjustment strip hole 5, locking part 6, mounting plate 7, reinforcing longitudinal beam 8, reinforcing plate 9, protective cover 10, supporting steel column 11, groove-type connecting part 12, auxiliary plate 13, column base 14, reinforcing beam 15, decorative eaves 16, building body 17, decorative support body 18, grille 19, auxiliary strip hole 20, tripod body 21, roof beam 22, reinforcing beam 23, roof 24, thermal insulation board 25, eaves board 26.

[0030] The embodiment is basically as shown in the attached Figure 1As shown: The old building reinforcement structure suitable for urban renewal at least includes a decorative support body 18 arranged on the front, back, left and right sides of the old building body 17. In this embodiment, there is a distance between the decorative support body 18 and the ground floor of the old building body facing the street, and it is offset against the wall of the second floor. The decorative support body 18 is offset against the left and right sides of the old building body, and the offset part of the two is fixed by chemical bolts. A reinforcing longitudinal beam 8 is detachably connected between the decorative support body 18 located on the street side and the old building body 17; the decorative support body 18 includes a plurality of column bases 14 and a supporting steel column 11 detachably connected to the column base 14. The spacing between adjacent supporting steel columns 11 is the same as the spacing between the structural columns of the old building body 17, and a reinforcing cross beam 15 is detachably connected between adjacent supporting steel columns 11. The material of the supporting steel column 11, the reinforcing longitudinal beam 8 and the reinforcing cross beam 15 is preferably hot-dip galvanized steel.

[0031] like Figure 2 , Figure 3 As shown, the column base 14 includes a base plate, and a connecting steel member 2 is connected to each of the four corners of the base plate 1, and the connecting steel member 2 can be selected as a steel bar. The connecting steel member 2 is fixed to the base plate 1 by bolts, and the base plate 1 is bolted with a mounting base for fixing and mounting the supporting steel column 11. The mounting base includes a connecting plate 3 connected to the base plate 1 and a connector 4 fixedly mounted on the connecting plate 3. The connector 4 includes a square structure formed by connecting four steel plates, and the steel plates are provided with mounting holes for connecting to the supporting steel column 11. A triangular reinforcing plate 9 is welded to each steel plate, and the bottom of the reinforcing plate 9 is welded to the connecting plate 3 to enhance the stability of the connector 4, thereby ensuring the stability of the bottom of the supporting steel column 11.

[0032] like Figure 4 , 5 As shown, the mounting plate 7 is installed on the wall of the old building 17 by chemical bolts. The lower end of the supporting steel column 11 is connected to the connecting body 4 by high-strength bolts, and the upper side wall and the mounting plate 7 are respectively bolted with a groove-type connector 12. The specific connection method is: a plurality of first connection holes are respectively provided on the mounting plate 7 and the supporting steel column 11, and a second connection hole corresponding to the first connection hole is provided on the groove-type connector 12. In this way, the groove-type connector 12 and the mounting plate 7 can be fixed to the wall by chemical bolts through the preset first connection hole and the second connection hole at the same time, without the need for two-step installation (first two installation and then installation with a third party), which speeds up the assembly cycle. The notches of the two groove-type connectors 12 are opposite, and the two ends of the reinforcement longitudinal beam 8 are respectively fixed to the groove-type connector 12 by high-strength bolts. According to the actual situation, several more reinforcement longitudinal beams can be set in the same place.

[0033] Two adjacent supporting steel columns 11 are also connected with grooved connectors 12 by corresponding bolts, and both ends of the reinforcement beam 15 are fixed to the grooved connectors 12 by high-strength bolts.

[0034] Auxiliary plates 13 with hollow holes are installed on both sides of the mounting plate 7 and between the supporting steel columns 11 and the reinforcing cross beams 15, which can play a reinforcing role on the one hand and a decorative role on the other hand. Grilles 19 are installed between each supporting steel column 11 and the wall of the building body 17. The grilles 19 can be selected from storage partitions, New Year picture grilles, etc.

[0035] In addition, considering that in the actual renovation process, after the base plate 1 is fixedly installed on the ground, when installing the supporting steel column 11, the actual installation distance between the supporting steel column 11 and the old building 17 may be adjusted. Figure 2 As shown, the mounting base and the base plate 1 are designed to be bolted and the connection position is adjustable. Specifically, the mounting base and the base plate 1 are equipped with a position adjustment part, which includes a first adjustment bar hole opened on the front and rear sides of the base plate 1 and a second adjustment bar hole 5 opened on the connecting plate 3. The first adjustment bar hole and the second adjustment bar hole 5 are located on the same vertical projection plane. The first adjustment bar hole and the second adjustment bar hole 5 are installed with a locking member 6 for locking and fixing the base plate 1 and the mounting base. The locking member 6 is a high-strength bolt. A decorative protective cover 10 is installed on the side wall of the base plate 1. The decorative protective cover 10 can be made of decorative materials such as stone, which can play a protective and decorative effect.

[0036] Secondly, in order to allow the mounting base to have a wider adjustment range and ensure the support strength of the substrate 1, an independent auxiliary bar hole 20 is specially opened on the extension line of the second adjustment bar hole 5 of the substrate 1, so that the substrate 1 between the second adjustment bar hole 5 and the auxiliary bar hole 20 remains intact to ensure its support strength. When the mounting base is adjusted to a large distance to the right, the two ends of the first adjustment bar hole can be placed at the second adjustment bar hole 5 and the auxiliary bar hole 20 respectively, and locked and fixed by bolts.

[0037] Construction method: Connect the installation base, base plate 1 and connecting steel parts 2 as a whole, then drill pile holes at the locations corresponding to the four connecting steel parts 2 on the ground, then pour concrete into the pile holes and insert the connecting steel parts 2 on the base plate 1 into the concrete in the pile holes, and after the concrete reaches the designed strength, set the supporting steel column 11 outside the connecting body 4 and connect and fix the two by bolts, and finally install the marble decorative protective cover 10 around the base plate 1. Fix the mounting plate 7 on the wall of the old building 17, and bolt the longitudinal beam 8 between the mounting plate and the supporting column, and bolt the cross beam 15 between adjacent supporting steel columns 11.

[0038] Example 2

[0039] The decorative support 18 is installed with decorative eaves on each floor corresponding to the old building. Specifically: two reinforcement beams 15 are set on each floor and are distributed at an upper and lower interval. A grille 19 is connected between the two reinforcement beams 15, which can not only play a reinforcement effect but also achieve a decorative effect. The decorative eaves 16 are installed on the top reinforcement beam 15. The decorative eaves 16 protrude outward from the supporting steel column 11 in the direction away from the building 17. In this solution, the decorative eaves 16 adopt antique eaves 16, such as hip roof, gable roof, hip roof, etc., to make the updated building facade more beautiful.

[0040] Example 3

[0041] Due to lack of management, residents of old buildings arbitrarily build temporary facilities on the roofs. Because the shape and material are very different from the architectural style, the building parts are out of tune with the surrounding environment, affecting the overall image of the town streets. In the process of designing the roof, considering that the newly added roof will affect the load-bearing capacity of the old building, some will directly abandon the plan of adding a new roof. However, for commercial streets that need to create specific needs such as antique architectural styles, abandoning the roof will greatly affect the overall viewing of the building complex.

[0042] Based on this background, Figure 6 As shown, this embodiment designs a technical solution that can add a new roof without causing a burden on the load-bearing capacity of the old building 17, specifically: the roof structure is detachably connected to the decorative support body 18, which includes a beam-column unit and a top surface unit detachably installed on the beam-column unit, the beam-column unit includes a tripod body 21 and a roof beam 22, and the three ends of the tripod body 21 are detachably connected to the roof beam 22, specifically: groove-type connectors 12 are bolted to the opposite surfaces of two adjacent tripod bodies 21, and the two ends of the roof beam 22 are respectively mounted on the groove-type connectors 12 of the left and right tripod bodies 21 and fixed by high-strength bolts.

[0043] In addition, a reinforcing beam 23 is horizontally installed in the middle of the tripod body 21, and a triangular cavity is enclosed between the reinforcing beam 23 and the tripod body 21, and a grille 19 is arranged in the triangular cavity. In this way, the arrangement of the reinforcing beam 23 and the grille 19 further strengthens the stability of the tripod body 21 on the one hand, and enhances the decorative sense of the roof on the other hand.

[0044] The cross section of the top unit is triangular, and includes a roof 24 and a heat-insulating board 25 located below the roof 24. The heat-insulating board 25 adopts an existing integrated heat-insulating board 25, which has played a role in heat-insulating the building 17. The edges of the top unit are detachably connected with a fascia board 26. Specifically, a clamping groove is provided on each fascia board 26, and the edges of the roof 24 and the heat-insulating board 25 are clamped into the clamping groove on the fascia board 26 and fixed by bolts.

[0045] In this embodiment, the roof structure is separated from the original building by a decorative support body and is independently supported on the ground. Therefore, the roof structure in this solution will not cause load-bearing risks to the original old building. At the same time, the roof structure in this solution can be redesigned into a new roof style according to new functional, aesthetic and other requirements, such as antique-style buildings, which greatly improves the overall viewing experience of the updated building complex.

[0046] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
