Description

Technical Field

[0001] The utility model belongs to the technical field of building structure reinforcement, and more specifically, relates to a reinforcement structure for newly added heavy equipment on the roof. Background Art

[0002] In the prior art, during building reconstruction and expansion, it is often necessary to place relatively heavy equipment on the roof, such as cooling towers. The conventional method is to directly place the equipment on the roof, which has a greater impact on the use of the existing building; the original roof surface layer within the equipment range needs to be largely chiseled, which easily forms a potential leakage hazard; for the reinforcement construction of the original roof beam and slab within the equipment range, the lower indoor rooms need to be suspended, the ceiling removed, and the ceiling reinstalled after the reinforcement is completed, which not only increases the project cost but also affects the construction period.

[0003] Corresponding improvements have also been made to the above problems. For example, Chinese Patent Application No. CN202022209224.7, with a publication date of June 11, 2021, discloses a roof equipment support structure, including a structural steel beam arranged on the roof, a unit support member, and an equipment foundation frame. The unit support member includes a steel structure pier, a vapor barrier layer laid on the roof foundation, and a water barrier layer laid on the vapor barrier layer. The bottom of the steel structure pier is welded and fixed to the structural steel beam, and a first insulation layer is also provided between the vapor barrier layer and the water barrier layer; the water barrier layer is successively composed of a base coil layer, an intermediate coil layer, and a surface coil layer from bottom to top; one side of the intermediate coil layer and the surface coil layer extends upward along the steel structure pier, and the top of the intermediate coil layer is flush with the top of the surface coil layer. The disadvantage of this patent is that although the structure is stable, the overall construction period is long and the efficiency is slow.

[0004] Another example is Chinese Patent Application No. CN201710682282.1, with a publication date of January 30, 2018. This patent discloses a reinforcement method and a reinforcement structure for the roof where the equipment foundation is installed. The reinforcement method includes: selecting a preset range for installing equipment on the roof where the equipment foundation is to be installed; finding the column head of the frame column on the roof within the preset range, vertically implanting steel bars into the frame column, embedding embedded parts, and pouring concrete to form a support column vertically opposite to the frame column; installing a support beam on the support column; and arranging a composite floor on the support beam. The disadvantage of this patent is that although the construction period is shortened, the overall stability needs to be strengthened. Summary of the Utility Model

[0006] In view of the problems that the existing renovation and expansion cause great damage to the original roof surface layer and have a long construction period, the utility model provides a reinforcement structure for adding heavy equipment on the roof.

At the same time, during construction, only the surface layer at the position of the frame column needs to be chiseled, minimizing the damage to the original roof surface layer as much as possible on the premise of ensuring structural safety, greatly shortening the construction period and avoiding the potential leakage problem.

[0007] 2. Technical Solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0026] The following further describes the utility model in combination with specific embodiments and drawings.

[0027] Embodiment 1

[0028] As Figure 1 and Figure 2 shown, a reinforcement structure for newly added heavy equipment on a roof includes a new column 2 and a support beam. The new column 2 is hinged to the original column 1. Specifically, the number of new columns 2 is several, corresponding to the number of original columns 1; and new columns 2 are hinged at the top of the original column 1. It should be noted that since the steel bars at the top of the original column 1 are relatively dense, if the new column 2 is directly rigidly connected to the original column 1, it will increase the construction difficulty; therefore, in this application, the top of the original column 1 is extended and the new column 2 is hinged. Compared with rigid connection, hinged connection reduces the constraint on the relative movement between the new column 2 and the original column 1, making the structure more smooth during deformation, avoiding stress concentration and damage that may be caused by rigid connection; and the hinged setting enables relative rotation between the new column 2 and the original column 1 when bearing loads, this design increases the flexibility of the structure, enabling the entire structure to better adapt to and disperse stress when subjected to external forces; in terms of construction, hinged connection is relatively simple, and complex connection processes and the number of components can be reduced during construction, reducing construction difficulty and cost.

[0029] The support beam is perpendicular to the new column 2 and the support beam supports on the new column 2. The support beam is used to place heavy equipment; that is, several new columns 2 are connected by the support beam, and the support beam is perpendicular to the new column 2; here the support beam has two functions: One: Together with the new column 2, it forms a frame structure to ensure the stability of the entire structure; Two: And the most important point is that the support beam is used to place heavy equipment, so that the weight of the heavy equipment is all borne by the support beam.

[0030] A connection strengthening part is arranged inside one end of the new column 2 where it is connected to the original column 1, that is, a connection strengthening part is arranged inside the bottom of the new column 2. The connection strengthening part makes the center of gravity of the new column 2 sink, so as to be more stably arranged on the top of the original column 1, and the connection strengthening part can strengthen the connection between the new column 2 and the original column 1.

[0031] The utility model hinges a new column 2 at the top on the existing roof frame column, which can reduce complex connection processes and the number of components during construction, reducing construction difficulty and cost; the support beam on the new column 2 is used to bear the equipment weight, avoiding the reinforcement of the original components within the range of the newly added heavy equipment. At the same time, during construction, only the surface layer at the position of the frame column, that is, the original column 1, needs to be chiseled. On the premise of ensuring structural safety, the damage to the original roof surface layer is minimized as much as possible, greatly shortening the construction period, and at the same time avoiding the formation of water leakage hazards; and a connection strengthening part is arranged inside the end of the new column 2 where it is connected to the original column 1, making the connection point more firm and capable of bearing greater shear force and tensile force, thereby improving the stability of the entire structure.

[0032] In a specific embodiment, the connection strengthening part is a steel bar mesh 4. The steel bar mesh 4 is a mesh structure. Through its mesh structure, the connection points between the new column 2 and the original column 1 can be dispersed, forming multiple stress points, thereby significantly improving the overall strength of the connection. This structural advantage makes the connection between the columns more stable and able to bear greater loads. Moreover, using the steel bar mesh 4 can greatly simplify the construction process at the column connection, reduce cumbersome processes such as on-site steel bar tying, thus speeding up the construction progress. And due to the structural characteristics of the steel bar mesh 4 itself, it has a fast forming speed and stable quality, and can be quickly installed and fixed, improving construction efficiency.

[0033] Preferably, in this embodiment, the steel bar mesh 4 includes a number of horizontally arranged steel bars and a number of vertically arranged steel bars that cross and are welded. The outer periphery of the steel bars is coated with a protective layer, and the protective layer sequentially includes a first anti-corrosion layer, an adhesive layer, and a second anti-corrosion layer from the inside to the outside. The setting of the protective layer greatly improves the anti-corrosion ability of the steel bar mesh 4, thereby ensuring that it still maintains good use characteristics in a harsh environment.

[0034] In a specific embodiment, a number of column longitudinal bars 3 are further provided inside the new column 2. The part of the number of column longitudinal bars 3 located at the bottom of the new column 2 is bent. It should be noted here that the column longitudinal bars 3 will jointly bear the longitudinal pressure with the concrete, and enhance the overall bearing capacity of the new column 2 through the tensile strength of the steel bars. Under the compressive state, the concrete bears the pressure, while the steel bars bear the tension, and the two work together, making the bearing capacity of the new column 2 significantly improved. And by reasonably configuring the column longitudinal bars 3, the cross-sectional size of the new column 2 can be reduced on the premise of ensuring the bearing capacity of the new column 2. This can not only save materials and reduce project costs, but also increase the usable space of the building. However, due to the dense steel bars at the top of the original column 1, it is difficult to construct if all the column longitudinal bars 3 are implanted into the original column 1. On the premise that the connection between the new column 2 and the original column 1 in this application has met the stability requirements, the column longitudinal bars 3 in this application do not need to extend into the original column 1. The part of the column longitudinal bars 3 located at the bottom of the new column 2 is bent to form a bending part, and the bending part is connected to the steel bar mesh 4, so that the column longitudinal bars 3 and the steel bar mesh 4 form a whole, enhancing the strength of the overall structure and reducing the construction difficulty at the same time.

[0035] In a specific embodiment, as Figure 3 and Figure 4 shown, it further includes shear-resistant steel bars 5, and the shear-resistant steel bars 5 are arranged through between the new column 2 and the original column 1. Specifically, since the new column 2 will inevitably bear horizontal shear force, the setting of the shear-resistant steel bars 5 can bear the horizontal shear force received by the new column 2, thereby ensuring the stability of the new column 2. The shear-resistant steel bars 5 can be appropriately adjusted according to the steel bar arrangement at the top of the original column 1, greatly reducing the construction difficulty.

[0036] In a specific embodiment, the shear-resistant steel bars 5 penetrate from the bottom of the new column 2 to the top of the original column 1, and the length of the shear-resistant steel bars 5 is limited to avoid the interference between the overly long shear-resistant steel bars 5 and the surrounding components during construction, thereby reducing the construction difficulty.

[0037] In a specific embodiment, the support beam includes a transverse beam extending horizontally and a longitudinal beam extending longitudinally, and the new column 2 is located at the intersection of the transverse beam and the longitudinal beam. The cross-setting of the transverse beam and the longitudinal beam for the support beam can form a stable grid structure, which can effectively disperse and bear the loads from different directions, improve the stability and load-bearing capacity of the overall structure, and make it not easily deformed when bearing heavy equipment for a long time; at the same time, setting the new column 2 at the intersection of the transverse beam and the longitudinal beam is equivalent to additional reinforcement at this key node, which can significantly improve the stability and load-bearing capacity of the entire support beam system and reduce the risk of structural damage caused by local stress concentration.

[0038] The examples of the present utility model only describe the preferred embodiments of the present utility model, and do not limit the concept and scope of the present utility model. Without departing from the design idea of the present utility model, various deformations and improvements made by those skilled in the art to the technical solutions of the present utility model shall fall within the protection scope of the present utility model.
