Description

Technical Field

[0001] This utility model relates to the field of prefabricated component installation technology, and in particular to a prefabricated component fixing device. Background Technology

[0002] Prefabricated components are components assembled and connected from prefabricated components as the main load-bearing components. Prefabricated columns, as load-bearing components, are used to bear the loads transmitted by the floor slabs and play an irreplaceable role in building structures. After the columns are installed, they usually need to be reinforced and supported by diagonal bracing to ensure the stability and plumbness of the column connection.

[0003] A search revealed a Chinese patent with publication number CN202120035139.5, which discloses a fixing device for prefabricated components. By incorporating a support frame, when reinforcing the column after assembly, it is unnecessary to install fasteners on the outer wall of the column. Two tie bolts are used to clamp two rib plates onto the outside of the column, allowing the top of the diagonal brace to be installed with one of the rib plates. This avoids damage to the column surface caused by direct installation. The two rib plates are movably connected to the column, and their height can be adjusted as needed during installation. Furthermore, both ends of the diagonal brace are hinged to the clamping plate and positioning plate via two hinge seats, making it more flexible and convenient to use.

[0004] The above-mentioned technical solution has the following drawbacks: although such component fixing device does not require drilling or damaging the prefabricated column, in actual use, the whole needs to be temporarily assembled during installation, which is inconvenient. Moreover, the contact area with the column is small, and the supporting pressure of the prefabricated component is large. In order to facilitate installation at the column and to improve applicability by splicing as needed, a prefabricated component fixing device is proposed. This device can stably fix and support the prefabricated column placed on the ground to ensure the stability and plumbness of the column connection. In addition, the whole device is foldable for easy transportation and subsequent reuse.

[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] This utility model provides a prefabricated component fixing device that solves the problems mentioned in the background. It can stably fix and support prefabricated columns placed on the ground to ensure the stability and plumbness of the column connection. The whole device is foldable for easy transportation and easy to reuse in the future.

[0008] The present invention provides the following solution to the above-mentioned technical problems: A prefabricated component fixing device includes an upper support plate, a load-bearing base, a fixed anchor rod, an assembly cover, and fixing bolts. The load-bearing base is uniformly equipped with connecting plates, and a lower support plate is fixedly connected to the load-bearing base. The top of the lower support plate is rotatably connected to the upper support plate. The upper support plate has a groove in which a first-order locking strip is installed. The lower support plate has a groove in which a second-order locking strip is installed. Both the upper and lower support plates have two first-order and two-order locking strips. The load-bearing base is fixedly equipped with a connecting base, and an external sleeve is rotatably connected to the connecting base. An internal support rod is slidably connected to the external sleeve. The lower support plate is fitted with a column base, and the upper support plate is fitted with a prefabricated column.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the connecting plate has anchor holes adapted to the fixed anchor rods, allowing the fixed anchor rods to pass through the connecting plate and be inserted into the ground for positioning.

[0011] Furthermore, both the first and second card strips are designed with an L-shaped structure, and the two card strips can be assembled into a T-shaped structure. The two first card strips and the two second card strips can be positioned by assembling a cover.

[0012] Furthermore, the inner wall of the assembly cover is provided with a T-shaped groove that is compatible with the first and second locking strips.

[0013] Furthermore, the outer walls of the external sleeve and the internal support rod are evenly provided with bolt holes that are compatible with the fixing bolts. After the external sleeve and the internal support rod are adjusted in length by extension or retraction, they can be positioned by the fixing bolts.

[0014] Furthermore, mounting brackets are fixedly installed on both sides of the outer wall of the upper support plate, and the upper support plate is rotatably connected to the built-in support rod through the mounting brackets.

[0015] Furthermore, each set of load-bearing bases is fixedly installed with four sets of connecting plates.

[0016] Furthermore, the load-bearing base is a rectangular frame structure with a reinforcing plate in the middle of the inner wall, so that the load-bearing base can stably support the column on the ground.

[0017] This utility model provides a prefabricated component fixing device, which has the following advantages:

[0018] 1. After the column base is hoisted onto the top of the prefabricated column, multiple sets of fixing devices can be set on all four sides, thereby achieving large-area contact fixing support on multiple sides, which has a better support effect and prevents cracking and damage to the components caused by small-area support.

[0019] 2. The load-bearing base can be installed on the ground by fixing the anchor rods. The upper support plate on the top of the lower support plate can be rotated and erected. After the bolt holes of the outer sleeve and the inner support rod are aligned, they can be fixed by fixing bolts, so that the upper support plate can support the column.

[0020] 3. The No. 1 and No. 2 clips at the connection of adjacent upper support plates can be connected by fitting an assembly cover, so that the two upper support plates can be spliced ​​together to support the prefabricated column. The spliced ​​upper support plates with increased width can also support wide columns, making the device more versatile.

[0021] 4. When disassembly and assembly are required, simply remove the fixed anchor rod and remove the assembly cover connected to the upper support plates on both sides to separate the two fixing devices. The upper support plate and the load-bearing base can be folded and stored. The built-in support rod that is stored in the outer sleeve can be positioned by fixing bolts, so that the upper support plate and the load-bearing base can be kept in a folded state for easy transportation and handling.

[0022] 5. This type of prefabricated component fixing device is not only easy to unfold and use quickly, and fold and store, but also can be spliced ​​together. It is not only suitable for common strip prefabricated columns, but also for wide prefabricated walls. It has good applicability, and its simple structure makes it easy to operate, which can effectively improve construction efficiency.
