Description

Technical Field

[0001] The utility model relates to the technical field of fixing tools, in particular to a formwork fixing tool. Background Art

[0002] During the infrastructure construction process, both the pile foundation and the foundation outcrop are circular. The diameter of the foundation excavation is basically the same as the diameter of the formwork for the outcrop part. However, due to geometric dimension deviations during the foundation pit excavation, there are often no effective support positions for the circular composite formwork when installing it at the hole opening.

[0003] In this regard, in the prior art, wooden square timbers are usually used to support the circular formwork. The support strength is relatively low, and the formwork is prone to deviation during the pouring process. Moreover, due to the lack of necessary reinforcement support around the circular formwork, the circular formwork often deforms, making it inconvenient to use. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a formwork fixing tool, which solves the technical problems in the prior art that wooden square timbers are used to support the circular formwork, the support strength is relatively low, and the formwork is prone to deviation during the pouring process. It has the advantages of being able to automatically fix and support the circular formwork, so that the circular formwork can be firmly installed at the foundation pit hole opening.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A formwork fixing tool includes an angle steel base. A circular formwork is placed on the angle steel base. A formwork support mechanism for fixing the circular formwork and preventing the formwork from deforming is provided on the angle steel base. An installation auxiliary mechanism for leveling the formwork is provided at the lower end of the angle steel base. When fixing the formwork, the staff will first use the installation auxiliary mechanism to fix the angle steel base at the upper end of the foundation pit, then place the circular formwork on the angle steel base. Subsequently, the formwork support mechanism will fix the circular formwork. The formwork support mechanism includes fixed bumps fixedly installed on the angle steel base. Rectangular sliding grooves are symmetrically opened at the upper end of the angle steel base. Movable bumps are slidably connected to the rectangular sliding grooves. Guide sliding rods and a driving assembly are symmetrically arranged on the fixed bumps. When the staff places the circular formwork between the movable bumps and the fixed bumps, the movable bumps will approach the fixed bumps under the action of the driving assembly, thereby fixing the circular formwork.

[0006] Preferably, the driving assembly includes a driving lead screw movably installed on the fixed bump. The driving lead screw is in threaded cooperation with the movable bump. The guide sliding rod is slidably connected to the movable bump. When the driving lead screw rotates, it will make the movable bump move back and forth along the rectangular sliding groove.

[0007] Preferably, annular hoops are respectively arranged on the movable bump and the fixed bump, which can effectively increase the contact area between the fixing tool and the circular template, thereby preventing the circular template from deforming.

[0008] Preferably, a micro motor and a storage battery are arranged inside the fixed bump. The micro motor is in transmission connection with the driving lead screw. When the micro motor operates, the driving lead screw rotates around its own axis.

[0009] Preferably, the installation auxiliary mechanism includes a supporting round rod fixedly installed at the lower end of the angle steel base. A rotating sleeve is movably installed at the lower end of the supporting round rod. A fixed cone is fixedly installed at the lower end of the rotating sleeve. After the staff places the angle steel base at the upper end of the foundation pit, the fixed cone will be inserted into the ground, thereby limiting the position of the angle steel base.

[0010] Preferably, the rotating sleeve is in threaded cooperation with the supporting round rod. When the rotating sleeve rotates, the distance between the supporting round rod and the fixed cone will change.

[0011] By means of the above technical solutions, the present utility model provides a template fixing tool, which at least has the following beneficial effects:

[0012] 1. By setting the template support mechanism, through the mutual cooperation between the driving component and the guiding slide rod, the present utility model can automatically fix and support the circular template, enabling the circular template to be firmly installed at the opening of the foundation pit. Moreover, the annular hoop can support and reinforce the outside of the circular template, effectively preventing the circular template from deforming, and is convenient to use.

[0013] 2. By setting the installation auxiliary mechanism, through the mutual cooperation between the rotating sleeve and the supporting round rod, the present utility model can quickly adjust the height of the corner of the angle steel base during the installation process of the angle steel base. In this way, even if the ground near the foundation pit is uneven, the angle steel base can still be kept in a relatively horizontal state, thereby preventing the circular template from tilting.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1

[0022] In the prior art, wooden squares are usually used to support the circular template 2, and the support strength is relatively low. During the pouring process, the template is prone to shift. Moreover, due to the lack of necessary reinforcement support around the circular template 2, the circular template 2 often deforms, making it inconvenient to use. To solve this technical defect in the prior art, as Figures 1-4 shown, this embodiment proposes a template fixing tool that can automatically fix and support the circular template 2 and can support and reinforce the outside of the circular template 2, which can effectively prevent the circular template 2 from deforming. The fixing tool includes an angle steel base 1 on which the circular template 2 is placed. The angle steel base 1 is provided with a template support mechanism 3 for fixing the circular template 2 and preventing the template from deforming. The lower end of the angle steel base 1 is provided with an installation auxiliary mechanism 4 for leveling the template. When fixing the template, the staff will first use the installation auxiliary mechanism 4 to fix the angle steel base 1 at the upper end of the foundation pit, then place the circular template 2 on the angle steel base 1, and subsequently, the template support mechanism 3 will fix the circular template 2.

[0023] In order to firmly install the circular template 2 at the upper end of the foundation pit opening, a template support mechanism 3 is provided in this embodiment. Specifically, the template support mechanism 3 includes a fixed convex block 301 fixedly installed on the angle steel base 1. Rectangular chutes 302 are symmetrically opened at the upper end of the angle steel base 1. An active convex block 303 is slidably connected to the rectangular chute 302. Ring-shaped hoops 304 are respectively arranged on the active convex block 303 and the fixed convex block 301, which can effectively increase the contact area between the fixing tool and the circular template 2, thereby preventing the circular template 2 from deforming. Guide slide rods 305 and a driving assembly 306 are symmetrically arranged on the fixed convex block 301. The driving assembly 306 includes a driving lead screw movably installed on the fixed convex block 301. The driving lead screw is in threaded cooperation with the active convex block 303. The guide slide rod 305 is slidably connected to the active convex block 303. When the staff places the circular template 2 between the active convex block 303 and the fixed convex block 301, the active convex block 303 will approach the fixed convex block 301 under the action of the driving assembly 306, thereby fixing the circular template 2. A micro motor and a storage battery are arranged inside the fixed convex block 301. The micro motor is in transmission connection with the driving lead screw. When the micro motor operates, the driving lead screw will rotate around its own axis.

[0024] In order to prevent the circular template 2 from skewing during the pouring process, an installation auxiliary mechanism 4 is provided in this embodiment. Specifically, the installation auxiliary mechanism 4 includes a support round rod 401 fixedly installed at the lower end of the angle steel base 1. A rotating sleeve 402 is movably installed at the lower end of the support round rod 401. The rotating sleeve 402 is in threaded cooperation with the support round rod 401. When the rotating sleeve 402 rotates, the distance between the support round rod 401 and the fixed cone 403 will change. A fixed cone 403 is fixedly installed at the lower end of the rotating sleeve 402. After the staff places the angle steel base 1 on the upper end of the foundation pit, the fixed cone 403 will be inserted into the ground, thereby limiting the position of the angle steel base 1.

[0025] In this embodiment, during infrastructure operations, the staff will first place the angle steel base 1 on the upper end of the foundation pit and let the columnar steel reinforcement cage pass through the inside of the angle steel base 1, and then place the circular template 2 on the angle steel base 1 in the manner as Figure 1 shown.

[0026] Moreover, when preventing the angle steel base 1, the staff can manually rotate the rotating sleeve 402 to raise or lower the height of one side of the angle steel base 1, thereby leveling the angle steel base 1. Therefore, even if the ground near the foundation pit is uneven, the angle steel base 1 can still be in a relatively horizontal state.

[0027] Next, the driving lead screw will rotate under the action of the micro motor. When the driving lead screw rotates, the movable convex block 303 will approach the fixed convex block 301, thereby fixing the position of the circular template 2. At the same time, the annular hoops 304 installed on the fixed convex block 301 and the movable convex block 303 will provide auxiliary support for the outside of the circular template 2, which can effectively prevent the circular template 2 from deforming during the pouring process.

[0028] In this embodiment, by setting the template support mechanism 3 and utilizing the mutual cooperation between the driving component 306 and the guiding slide rod 305, the circular template 2 can be automatically fixed and supported, enabling the circular template 2 to be firmly installed at the opening of the foundation pit. Moreover, the annular hoop 304 can support and reinforce the outside of the circular template 2, effectively preventing the circular template 2 from deforming, which is convenient to use. Additionally, in this embodiment, by setting the installation auxiliary mechanism 4 and utilizing the mutual cooperation between the rotating sleeve 402 and the supporting round rod 401, the height of the corner of the angle steel base 1 can be quickly adjusted during the installation of the angle steel base 1. In this way, even if the ground near the foundation pit is uneven, the angle steel base 1 can still be kept in a relatively horizontal state, thereby preventing the circular template 2 from tilting.
