Description

Technical Field

[0001] This utility model relates to the field of building column formwork technology, specifically a building column formwork support device. Background Technology

[0002] Building column formwork is a formwork support used in building construction for pouring concrete structures such as walls and columns;

[0003] For example, the Chinese authorized patent (Building Column Formwork Support Structure) with announcement number CN220621071U includes a fixing plate, a limiting frame, a corner guard, a support plate, sleeve holes, and a sleeve frame. Beneficial effects: This utility model, through the support and fixing structure set at the bottom of the formwork, allows for the insertion of reinforcing bars between the support plate and the formwork, with the corner guard fitting snugly against the formwork, and the reinforcing bars are inserted one-to-one with the sleeve holes. After the reinforcing bars are inserted, screws are passed through holes set on the surface of the support plate to secure them tightly. This strengthens the support and fixing of the reinforcing bars at the bottom of the formwork, preventing the bottom of the formwork from cracking due to the large impact force of the pouring above. Simultaneously, the multiple sets of sleeve holes and sleeve frames allow for adjustment of the support and fixing according to the size of the formwork.

[0004] However, existing concrete pouring methods exert significant impact on the bottom of the formwork, easily leading to cracking. Reinforcement using bolted reinforcing ribs requires multiple ribs, making installation and disassembly inconvenient and lacking flexibility. Therefore, these methods do not meet current needs. To address this, we propose a building column formwork support device. Utility Model Content

[0005] The purpose of this utility model is to provide a building column formwork support device to solve the problems mentioned in the background art, which are that when concrete is poured, it has a large impact force on the bottom of the formwork, which easily leads to cracking of the bottom formwork. The existing method of fixing reinforcing ribs with bolts is used for reinforcement, but multiple reinforcing ribs are required, which is inconvenient to install and disassemble and has poor flexibility.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a building column formwork support device, comprising: a formwork plate, wherein connecting columns are provided on all four sides of the formwork plate, and multiple connecting columns are provided. A movable groove is provided on the side surface of the connecting column near the bottom, and movable grooves are provided on both sides of the connecting column located between two connecting columns. The two connecting columns are connected by a reinforcing component, and the reinforcing component moves along the movable groove.

[0007] Preferably, one side surface at both ends of the movable groove is provided with an installation notch, and the installation notch communicates with the movable groove.

[0008] Preferably, the reinforcing component includes a first reinforcing arm and a second reinforcing arm, and the first reinforcing arm and the second reinforcing arm intersect in an X shape.

[0009] Preferably, the top ends of the first reinforcing arm and the second reinforcing arm are integrally formed with a first mounting end, and the bottom ends of the first reinforcing arm and the second reinforcing arm are integrally formed with a second mounting end. The first mounting end and the second mounting end are both inserted into the moving groove along the mounting notch, and the first mounting end and the second mounting end move up and down along the moving groove.

[0010] Preferably, the front surface of the movable groove near the bottom end is provided with a connecting hole, the rear surface of the movable groove near the bottom end is provided with a threaded hole, the front end of the second mounting end is provided with a through hole, the front end of the connecting hole is provided with a fixing pin, and one end of the fixing pin passes through the connecting hole and the through hole in sequence and is threadedly connected to the threaded hole.

[0011] Preferably, a first connecting frame is provided on the outside of the connecting columns on both sides of the template plate, and a second connecting frame is provided on the outside of the connecting columns on the other two sides of the template plate. The second connecting frame is located at the upper end of both ends of the first connecting frame, and the first connecting frame and the second connecting frame are fixed by single-head fasteners.

[0012] Preferably, both the first connecting frame and the second connecting frame are fixed to the connecting column by fixing bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model provides a reinforcing component between two connecting columns. During fixing, the first and second mounting ends of the first and second reinforcing arms are inserted into the moving groove along four mounting notches. Then, the first and second reinforcing arms are moved downwards, causing the mounting ends to be misaligned with the mounting notches, thus limiting the reinforcing component and preventing it from falling out. The reinforcing component strengthens the bottom of the formwork, preventing cracking during pouring, improving safety and support. Furthermore, the quick-disassembly design of the reinforcing component enhances installation and disassembly flexibility and convenience, facilitating rapid assembly and improving work efficiency. This solves the problem that existing methods of reinforcing with bolts, which require multiple reinforcing ribs and are inconvenient to install and disassemble due to the significant impact of concrete pouring on the bottom of the formwork, leading to cracking, are problematic.

[0015] 2. By setting a connecting hole on the front surface of the moving groove near the bottom and a threaded hole on the rear surface of the moving groove near the bottom, when further strengthening of stability is required, one end of the fixing pin passes through the connecting hole and the through hole in sequence and is threadedly connected to the threaded hole to fix the reinforcing component, thereby improving stability. It can be used selectively according to needs, thus improving flexibility. Attached Figure Description
