Description

Technical Field

[0001] The utility model relates to a suspension structure of a newly added hoist walking single-rail beam for an existing building. Background Art

[0002] In the design of industrial buildings, electric hoists are required to be installed at the bottom of the beams in many equipment maintenance rooms for equipment installation and maintenance hoisting, such as in fan rooms, pump rooms, and equipment rooms, etc. The electric hoist is suspended on the I-beam single-rail beam track, and the connection between the I-beam track and the concrete beam is made by bolt connection, that is, the bolt passes through the reserved bolt holes in the reinforced concrete beam, and both ends of the bolt are fixed with steel plate connection plates, and the lower part is bolt-connected to the I-beam single-rail beam. However, for some renovation projects, due to equipment maintenance requirements, it is necessary to change the position of the single-rail beam or add a new single-rail beam, so it is necessary to add a new single-rail beam on the concrete beam of the existing building. Generally, the common treatment method is to use a water drill to re-drill holes in the concrete beam and re-embed shear bolts. However, this method is inconvenient to operate, and there are the following disadvantages in using a water drill to drill holes in the concrete structure beam of the existing building:

[0003] 1) The track beam is suspended below the concrete beam, which belongs to high-altitude operation and has a relatively high risk factor;

[0004] 2) Since the distance between the drilling point and the floor slab is relatively close, the operation space is limited, which is not conducive to the implementation of drilling;

[0005] 3) The width of the concrete structure beam is relatively wide, and it is not easy to drill through, and the drilling quality is not easy to guarantee, which is time-consuming and laborious;

[0006] 4) Since the position of the steel bars in the concrete beam cannot be determined, drilling may cause damage to the steel bars in the concrete beam, posing a potential safety hazard to the structure. Summary of the Invention

[0007] In view of the above problems, the purpose of the utility model is to provide a suspension structure of a newly added hoist walking single-rail beam for an existing building. By setting a steel flat plate on the upper surface of the floor slab of the building beam and connecting the steel flat plate with channel steels arranged on both sides of the building beam through bolts, a hanging support for the hoist walking single-rail beam is formed, avoiding drilling holes in the building beam.

[0008] In order to achieve the above purpose, the solution of the utility model is:

[0009] A suspension structure for adding a monorail beam for the movement of a hoist to an existing building, comprising a plurality of concrete beams and a monorail I-beam steel connected and supported under a building floor slab. The monorail I-beam steel is used for the movement of lifting equipment. The monorail I-beam steel is suspended under the concrete beam by a hoist, wherein: the hoist comprises a flat steel plate and a "U"-shaped channel steel. The flat steel plate is laid on the upper surface of the building floor slab. There are two "U"-shaped channel steels, which are separately arranged on both sides of the concrete beam. Through holes are respectively drilled in the building floor slab on both sides of the concrete beam. Connecting through holes are respectively arranged on one side of the flat steel plate and the channel wall of the "U"-shaped channel steel in cooperation with the through holes in the building floor slab. Steel connecting bolts are used to pass through the through holes in the flat steel plate, the building floor slab and the channel wall on one side of the "U"-shaped channel steel to connect and fix the two "U"-shaped channel steels to the building floor slab. The monorail I-beam steel is connected and fixed to the channel walls on the other side of the two "U"-shaped channel steels through I-beam bolts to form the suspension of the monorail I-beam steel under the concrete beam.

[0010] A further solution is that the two "U"-shaped channel steels are separately and closely arranged on both sides of the concrete beam.

[0011] A further solution is that the "U"-shaped channel steel is a profiled channel steel or a "U"-shaped channel steel formed by right-angle welding of three steel plates. Reinforcing rib plates are connected and arranged between the channel walls on both sides of the "U"-shaped channel steel formed by right-angle welding.

[0012] Compared with the prior art, the utility model has the following characteristics and beneficial effects:

[0013] 1) The implementation of the utility model only needs to operate on the concrete floor slab, and the operation space is not restricted, which is easy to implement;

[0014] 2) There is no high-altitude operation in the utility model, and the risk factor is relatively small;

[0015] 3) The utility model only needs to drill a few bolt holes on the floor slab, which causes less damage to the floor slab. Because the floor slab is relatively thin, the drilling quality is easy to guarantee, saving time and effort;

[0016] 4) The utility model will not damage the steel bars of the concrete beam and will not pose a potential safety hazard to the structural safety;

[0017] 5) The utility model transfers the load to the top of the concrete structural beam through the upper connecting plate of the floor slab, and makes the lower connecting plate of the floor slab and the upper connecting plate of the floor slab close to the floor slab through bolt fastening, so that the beam-slab system bears force together, improves the force-bearing performance and ensures the structural safety.

[0018] The following is a detailed description of the utility model in conjunction with the drawings and embodiments. Description of the Drawings

[0020] Figure 2 It is a side view schematic diagram of the structure of the present utility model. Specific implementation manner

[0021] A suspension structure for adding a single-track beam for a hoist to walk on an existing building, as Figure 1 and Figure 2 shown, includes a plurality of concrete beams 2 (only one concrete beam is schematically shown in the figure) connected and supported under the building floor slab 1 and a single-track I-shaped steel beam 3. The single-track I-shaped steel beam 3 is used for the walking of lifting equipment (such as a hoist, not schematically shown in the figure). The single-track I-shaped steel beam 3 is suspended under the concrete beam 2 through a hoist. Among them: The hoist includes a flat steel plate 4 and a "U"-shaped channel steel 5. The flat steel plate 4 is laid on the upper surface of the building floor slab 1. The "U"-shaped channel steel 5 is in two pieces, and the two pieces of "U"-shaped channel steel 5 are separately arranged on both sides of the concrete beam 2. Through holes are respectively drilled in the building floor slab 1 on both sides of the concrete beam 2. Connecting through holes are respectively arranged on the flat steel plate 4 and one side groove rib 501 of the "U"-shaped channel steel 5 in cooperation with the through holes of the building floor slab 1. Steel plate connecting bolts 6 are used to pass through the through holes of the flat steel plate 4, the building floor slab 1 and one side groove rib 501 of the "U"-shaped channel steel 5 to connect and fix the two pieces of "U"-shaped channel steel 5 with the building floor slab 1. The single-track I-shaped steel beam 3 is connected and fixed with the other side groove ribs 502 of the two pieces of "U"-shaped channel steel 5 through I-shaped steel connecting bolts 7 to form the suspension of the single-track I-shaped steel beam 3 under the concrete beam 2.

[0022] Among them: In order to ensure the stability of the "U"-shaped channel steel, the two pieces of "U"-shaped channel steel 5 are separately and closely arranged on both sides of the concrete beam 2. The "U"-shaped channel steel 5 can adopt profile channel steel, or a "U"-shaped channel steel formed by right-angle welding of three steel plates. In order to ensure the strength, a reinforcing rib plate 503 is connected and arranged between the two side groove ribs of the "U"-shaped channel steel formed by right-angle welding.

[0023] The above-mentioned embodiment of the suspension structure of the new monorail beam for the hoist to travel on the existing building solves the technical problem that the new monorail beam cannot be connected to the concrete structure beam of the existing building, and at the same time avoids a series of disadvantages such as high-altitude operation, limited space, difficult quality assurance, and damage to the steel bars of the structure beam caused by drilling the structure beam; by setting a steel flat plate on the upper surface of the floor slab of the building beam and connecting the steel flat plate with channel steels arranged on both sides of the building beam through bolts to form the hanging support of the monorail beam for the hoist to travel, there is no need to damage the concrete structure beam and no potential safety hazard to the structural safety will be caused. Obviously, the building floor slab 1 and multiple concrete beams 2 are integrally cast structures. The load is transmitted to the top of the concrete structure beam 2 through the steel flat plate connected to the upper part of the building floor slab 1, and the channel steel plate connected to the lower part of the floor slab and the steel flat plate on the upper part of the floor slab are pressed against the floor slab through bolt fastening, so that each component of the suspension structure bears force together, improving the force-bearing performance and better ensuring the safety of the existing building structure.
