Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a prefabricated building beam bottom support device. Background Technology

[0002] In traditional concrete beam construction, full-span scaffolding or steel pipe support frames are typically erected under the beam to provide structural support during the construction phase. However, this type of support has several drawbacks: First, it requires a large quantity of materials such as steel pipes and fasteners, resulting in high rental and transportation costs and consuming significant warehousing and transportation resources; second, the erection process is cumbersome and time-consuming, impacting the overall project progress; and third, the stability of the support system largely depends on the skill level of the construction workers, making it susceptible to structural instability due to improper installation, posing a significant safety hazard.

[0003] To address this, existing technologies have attempted to use prefabricated support components to replace traditional scaffolding. While this has improved construction efficiency to some extent, it still suffers from problems such as poor adaptability, unclear force transmission paths, low connection reliability, and low reusability, making it difficult to meet the comprehensive requirements of efficient, safe, and green construction in current building projects. Therefore, a prefabricated beam-bottom support device for building beams is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated building beam bottom support device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building beam bottom support device, installed on a frame to support the bottom of the beam, comprising:

[0006] Several adjustable supports; and

[0007] The main load-bearing beam is installed on the frame via connectors, and several adjustable supports are installed on the main load-bearing beam. After installation, the several adjustable supports, the main load-bearing beam, and the connectors work together to form a stable load transfer path.

[0008] As a further embodiment of this utility model: the adjustable support includes a screw adjuster connected to the main load-bearing beam, and a buckle is installed at the end of the screw adjuster near the bottom of the beam.

[0009] As a further embodiment of this utility model: the buckle is U-shaped, and the U-shaped buckle has two oppositely arranged side walls, each of which has a groove.

[0010] As a further embodiment of this utility model: the main load-bearing beam includes a steel plate, and both ends of the steel plate are provided with through holes for the columns on the frame to pass through.

[0011] As a further embodiment of this utility model: the main load-bearing beam includes a connecting plate and movable plates disposed at both ends of the connecting plate. The movable plates are connected to the connecting plate by an external threaded rod, wherein a threaded sleeve threaded on the external threaded rod is rotatably connected to the end face of the movable plate adjacent to the connecting plate.

[0012] As a further embodiment of this utility model: the movable plate has a limiting hole for inserting the end of the external threaded rod, and the movable plate is also equipped with a limiting groove for the column on the frame to pass through.

[0013] As a further embodiment of this utility model: the movable block has a plurality of insertion holes, and a support rod connected to the connecting plate is inserted into each of the plurality of insertion holes.

[0014] Compared with existing technologies, the advantages of this invention are: through the coordinated operation of the main load-bearing beam, adjustable supports, and connectors, the construction load of the beam is transferred to the main structures on both sides, significantly reducing the amount of traditional support frames required. The device adopts a modular design, can be reused repeatedly, and has the advantages of quick installation, high safety, and low cost, making it suitable for high-rise buildings and large-span beam construction scenarios.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 In this embodiment of the present invention, a prefabricated building beam bottom support device is installed on a frame to support the bottom of the beam, comprising:

[0025] Several adjustable supports 2; and

[0026] The main load-bearing beam 1 is installed on the frame via connector 3, and several adjustable supports 2 are also installed on the main load-bearing beam 1. After installation, the several adjustable supports 2, the main load-bearing beam 1 and connector 3 work together to form a stable load transfer path.

[0027] Specifically, the frame is assembled from multiple columns and disc buckles (the combination of columns and disc buckles is existing technology, and those skilled in the art know how to assemble it, so it will not be elaborated here). The two ends of the main load-bearing beam 1 are connected to the columns on both sides of the beam bottom. By installing connectors 3 on the same horizontal plane on the two columns, the main load-bearing beam 1 is then fitted onto the two columns, so that the main load-bearing beam 1 and the connectors 3 are in contact. Several adjustable supports 2 are installed on the main load-bearing beam 1. The number of adjustable supports 2 is not limited. In this embodiment, preferably, there are two adjustable supports 2. Both adjustable supports 3 are fixedly installed on the main load-bearing beam 1, and their upper parts are in contact with the steel pipe 4 at the bottom of the beam. At this time, the load at the bottom of the beam is transferred to the ground in sequence through the timber, steel pipe 4, adjustable supports 2, and main load-bearing beam 1, forming a stable load transfer path. This can reduce the number of columns used in traditional beam bottom support frames and improve construction efficiency and safety.

[0028] Please see Figure 1In one embodiment, preferably, the adjustable support 2 includes a screw adjuster connected to the main load-bearing beam 1. A buckle is installed at one end of the screw adjuster near the bottom of the beam. The screw adjuster can adjust the height of the buckle. The buckle is U-shaped and has two opposite sidewalls with grooves on both sidewalls. When the height of the buckle does not match that of the steel pipe 4, the height of the buckle can be adjusted by a hydraulic lifter and / or the screw adjuster so that the position of the steel pipe 4 falls into the groove of the buckle, thereby preventing it from overturning.

[0029] Please see Figure 2 In one embodiment, preferably, the main load-bearing beam 1 includes a steel plate 11. Both ends of the steel plate 11 are provided with through holes for the columns on the frame to pass through. After the columns pass through the through holes, the steel plate 11 and the columns can be positioned relative to each other. The steel plate 11 has a through slot. The screw adjuster passes through the slot and is fixed on the steel plate 11. At the same time, the position can be adjusted within the range of the slot, thereby realizing the function of adjusting the distance between adjacent screw adjusters. After the screw adjuster passes through the steel plate, a nut is installed. By rotating the nut, its top is pressed tightly against the bottom of the steel plate 11, thereby realizing the fixed installation of the screw adjuster.

[0030] Please see Figure 3-5 In another embodiment, preferably, the main load-bearing beam 1 includes a connecting plate 12 and movable plates 13 disposed at both ends of the connecting plate 12. The movable plates 13 and the connecting plate 12 are connected by an external threaded rod 14, wherein the end face of the movable plate 13 adjacent to the connecting plate 12 is rotatably connected to a threaded sleeve 15 threaded on the external threaded rod 14.

[0031] Specifically, the connecting plate 12 has a through slot, through which the screw adjuster passes and is fixed to the connecting plate 12. Its position can be adjusted within the slot, thus adjusting the distance between adjacent screw adjusters. After passing through the steel plate, the screw adjuster is fitted with a nut. By rotating the nut, its top is pressed tightly against the bottom of the connecting plate 12, thus achieving a fixed installation. The distance between the two movable plates 13 and the connecting plate 12 can be adjusted as needed. When the length of the beam support device does not match the distance between the two columns, adjustment can be achieved by rotating the threaded sleeve 15, which is rotatably connected to the movable plate 13. Since the threaded sleeve 15 and the external threaded rod 14 are threadedly fitted, one end of the external threaded rod 14 is movably connected to the movable plate 13, while the other end is fixed to the connecting plate 12. Therefore, when the threaded sleeve 15 is rotated, the movable plate 13 can be moved along the external threaded rod 14, thereby changing the distance between it and the connecting plate 12. Through this adjustment method, the support frame can be adapted to beam bottom structures of different widths. Since the column spacing corresponding to different beam bottom widths is also different, this adjustment function effectively improves the applicability and flexibility of the device.

[0032] Please see Figure 5 In one embodiment, preferably, the movable plate 13 has a limiting hole 17 for the end of the external threaded rod 14 to be inserted, and the movable plate 13 is also equipped with a limiting groove 18 for the column on the frame to pass through. The limiting hole 17 is for the end of the external threaded rod 14 to be inserted, and the limiting groove 18 is opened on the side end face of the movable plate 13 to facilitate the insertion of the column into the interior of the limiting groove 18.

[0033] Please see Figure 5 In one embodiment, preferably, the movable block 13 has a plurality of insertion holes, and each of the plurality of insertion holes is into which a support rod 16 connected to the connecting plate 12 is inserted. These support rods are connected to the connecting plate 12, thereby effectively reinforcing the connection between the connecting plate 12 and the movable block 13.

[0034] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0035] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
