Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railing installation bases, in particular to a prefabricated bottom fixing seat for positioning and installing railing columns. Background Technique
[0002] When using the existing wooden formwork process to make railings, there are two ways to fix the bottom of the railing. One is to use embedded fixtures to position the bottom of the railing through the embedded fixtures, and the other is the post-grooving process, which fixes the bottom of the railing by installing positioning parts later.
[0003] The embedded fixture process requires steel bar welding, and the embedded fixtures are extremely prone to displacement during the concrete pouring process, resulting in the failure of the embedded parts. Subsequently, the post-grooving process still needs to be used when installing the railing; at the same time, the embedded fixtures need to be constructed by the in-situ casting method. Hollow formwork is assembled according to the shape and size of the building structure, and the formwork is fixed by using positioning means, and then concrete is poured into the formwork cavity. When the poured concrete solidifies and forms, the formwork is removed.
[0004] The post-grooving process needs to damage the existing concrete structure. By driving expansion bolts to construct the fixing base of the railing, it will damage the formed anti-camber, and even affect the formed fixing effect. Later, plastering and repairing are still required. For those with serious cracking, processes such as formwork support and re-pouring are needed.
[0005] Therefore, for the fixation of railings, whether using the construction process of embedded fixtures or the construction process of post-grooving, there are technical problems of labor waste, many processes, high costs and inability to guarantee quality.
[0006] It should be particularly noted that the above technical information is only intended to deepen the understanding of the overall background technology of the present utility model, and should not be regarded as an admission or any form of suggestion that the above technical information constitutes the prior art known to those skilled in the art. Summary of the Utility Model
[0007] In view of the deficiencies in the above background technology, the present utility model proposes a prefabricated bottom fixing seat for positioning and installing railing columns, which solves the technical problems of labor waste, many processes, high costs and inability to guarantee quality existing in the construction of railing fixing bases using the existing technology.
[0008] The technical solution of this application is as follows:

This technical solution overcomes the prejudice of the prior art, not only taking into account conventional prior art such as pre-embedded, cast-in-place, and slotted, but also eliminating the need to regard the pre-embedded positioning piece as only the railing post positioning piece itself, but pre-fabricating the railing post positioning piece and its accompanying concrete block as a whole, taking into account both pre-embedded and positioning, as well as post-casting of prefabricated pieces, and decoupling the complex cast-in-place process of the pre-embedded positioning piece into a process and corresponding structure combining assembly and anti-slope cast-in-place, which can be constructed in batches, ensure construction accuracy and reliability, and improve construction efficiency.

Of course, in addition to the above-mentioned array arrangement and the implementation method facing different directions, technicians in the relevant technical field can also choose other arrangement methods, and other methods are protected within the maximum protection scope of this application. This technical solution specifically emphasizes the protection of the embodiments of the array arrangement and facing different directions, and does not exclude the protection of other implementation methods.
[0013] On the basis of the above technical scheme, as an optimal technical scheme for the prefabricated bottom fixing seat used for positioning and installing the railing column, when the prefabricated bottom fixing seat is installed, the concrete block is clamped in the anti-ridge formwork of the cast-in-place structure through step-by-step tightening components, and the end of the anchor steel bar away from the fixed steel plate is in a suspended state, which is convenient for the combination of the concrete of the post-cast anti-ridge structure and the concrete block, and is convenient for the suspended section of the anchor steel bar to be connected with the anti-ridge structure reinforcement, thereby achieving the above-mentioned enhanced integrity, improved positioning reliability and flexibility.
[0014] On the basis of the above technical solution, as a preferred technical solution of the precast bottom fixing seat for positioning and installing the railing column, one end of the anchor reinforcement away from the fixing steel plate is connected to the structural reinforcement of the cast-in-place structure by binding wire or stirrups.

One end face of the fixing steel plate exposes the concrete block, and the other end faces are all located inside the concrete block.
[0019] Compared with the prior art, the technical solution provided by the present utility model has the following beneficial effects:
[0020] 1. It can effectively solve the problems of traditional wooden formwork technology for fixing the bottom of the railing by using embedded fixing parts or post-grooving, which involves a lot of manual waste, many processes, high costs and cannot guarantee the quality.
[0021] 2. It should be noted specifically that although the present technical solution and the prior art both involve embedded operations, the embedded scenarios and components are completely different. In the prior art, fixtures are directly embedded during the casting of the anti-camber, which is prone to misalignment and difficult to position. Moreover, it is necessary to construct positioning templates and casting templates for the embedded fixtures with specific positions, shapes, and sizes in the anti-camber formwork. In contrast, the present application decouples the construction process and the construction mold, decoupling it into two processes: prefabrication and in-situ casting. As a result, each process is independent, enabling not only standardization and mass production but also extremely simple and highly efficient corresponding construction structures for each process.
[0022] 3. The railing column positioning member is prefabricated on the concrete block, which not only avoids in-situ casting embedding but also avoids post-construction grooving. At the same time, the concrete block facilitates subsequent casting for integral formation, and it is easier to position the concrete block during the subsequent casting process without misalignment.
[0023] 4. The anchoring steel bars provided on the fixing steel plate can not only enhance the integrity between the concrete block and the subsequently cast anti-camber structure, thereby forming an integral body of the railing column positioning member, the concrete block, and the anti-camber structure to ensure the reliability of railing installation, but also position the concrete block during the casting of the anti-camber structure.
[0024] 5. This component can be mass-produced and installed in the factory, and only needs to be assembled and installed on-site. Through popularization and application, it can greatly improve the construction efficiency and economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS
