Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a fixing structure for building construction templates. Background Technique

[0002] A building formwork is a temporary support structure that bears the self-weight of the building formwork and the external loads acting on it. The purpose of formwork engineering is to ensure the quality of concrete works, construction safety, speed up the construction progress and reduce the project cost. When installing a building formwork, it needs to be reinforced through a fixing structure.

[0003] At present, when the existing fixing structure clamps a circular building construction formwork, it needs to be adjusted operationally in each direction one by one, resulting in a reduction in the fixing efficiency of the formwork. Moreover, when fixing a circular building formwork, it cannot be adjusted according to the size of the circular building formwork, resulting in low practicability.

[0004] Therefore, this case proposes a fixing structure for building construction templates to solve the above technical problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a fixing structure for building construction templates, which can effectively solve the technical problems in the background technique that during clamping and fixing, it is necessary to adjust operationally in each direction one by one, resulting in a reduction in the fixing efficiency of the formwork, and it cannot be adjusted according to the size.

The inner wall of the fixed ring is fixedly connected to an inner ring. Four sides of the top end of the rotating ring are all rotatably connected to fixed columns. Hydraulic rods are rotatably connected between the four fixed columns and the inner ring. Four sides of the inner wall of the rotating ring are all fixedly connected to arc-shaped triangular blocks. Four telescopic columns slide through the inner wall of the inner ring. One end of the four telescopic columns close to each other is fixedly connected to a clamping plate. Tension springs are fixedly connected between one end of the four clamping plates away from each other and the inner ring. A roller mechanism is arranged at one end of the four telescopic columns away from each other, and the roller mechanism is used to reduce friction.

[0008] As a further scheme of the utility model, one side of one end of the four clamping plates away from each other corresponding to the telescopic column is fixedly connected with a guiding column and penetrates through the inner ring.

[0009] As a further scheme of the utility model, the roller mechanism includes fixing plates symmetrically fixedly connected to the telescopic column. Fixed shafts are rotatably connected between the four groups of fixing plates. Rollers are fixedly connected to the outer walls of the four fixed shafts.

[0010] As a further solution of the present utility model, grooves are provided at one ends of the four clamping plates away from the inner ring, and are used to increase friction.

[0011] As a further solution of the present utility model, the four rollers are all in contact with the inner wall of the rotating ring, and the four rollers all roll along the arc surface of the arc-shaped triangular block.

[0012] As a further solution of the present utility model, the hydraulic rods are rotatably arranged on the outer wall of the inner ring, and the four tension springs are all arranged outside the telescopic columns.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Such as Figures 1-3As shown in the figure, a fixing structure for building construction templates includes a rotating ring 1. The bottom end of the rotating ring 1 is rotatably connected to a fixed ring 2. The inner wall of the fixed ring 2 is fixedly connected to an inner ring 3. Four sides of the top end of the rotating ring 1 are all rotatably connected to fixed columns 4. Hydraulic rods 5 are rotatably connected between the four fixed columns 4 and the inner ring 3. Four sides of the inner wall of the rotating ring 1 are all fixedly connected with arc-shaped triangular blocks 6. Four telescopic columns 7 are slidably penetrated through the four sides of the inner wall of the inner ring 3. The mutually approaching ends of the four telescopic columns 7 are all fixedly connected with clamping plates 8. Tension springs 9 are fixedly connected between the mutually remote ends of the four clamping plates 8 and the inner ring 3. The mutually remote ends of the four telescopic columns 7 are all provided with roller mechanisms 11, and the roller mechanisms 11 are used to reduce friction.

[0022] In this embodiment, guide columns 10 are fixedly connected to the sides of the mutually remote ends of the four clamping plates 8 corresponding to the telescopic columns 7 and penetrate through the inner ring 3. With the cooperation of the guide columns 10, the situation that the clamping plates 8 deflect can be prevented, and the stability is increased.

[0023] In this embodiment, the roller mechanism 11 includes fixing plates 1101 symmetrically and fixedly connected to the telescopic columns 7. Fixed shafts 1102 are rotatably connected between the four groups of fixing plates 1101. Roller wheels 1103 are fixedly connected to the outer walls of the four fixed shafts 1102. The roller wheels 1103 are installed on the telescopic columns 7 through the fixing plates 1101 and the fixed shafts 1102.

[0024] In this embodiment, grooves are formed at the ends of the four clamping plates 8 away from the inner ring 3 and are used to increase friction and prevent detachment after fixation.

[0025] In this embodiment, the four roller wheels 1103 are all in contact with the inner wall of the rotating ring 1. The four roller wheels 1103 all roll along the arc surface of the arc-shaped triangular block 6. During the rolling process, the friction can be reduced, which is convenient for the telescopic movement of the telescopic column 7. The hydraulic rods 5 are equally rotatably arranged on the outer wall of the inner ring 3. The four tension springs 9 are all arranged outside the telescopic columns 7.

[0026] It should be noted that the present utility model is a fixing structure for building construction templates. When in use, first place this fixing structure on the outside of a circular building template. By starting the hydraulic rods 5 and with the cooperation of the fixed columns 4, the rotating ring 1 can be rotated, and when rotating, the arc-shaped triangular block 6 can contact the roller wheels 1103, and the roller wheels 1103 roll on the arc surface of the arc-shaped triangular block 6, so that the telescopic columns 7 can be moved inward at the same time, and the clamping plates 8 can be clamped on the outside of the circular building template. Therefore, the circular building template can be fastened from four directions at the same time without adjusting one by one, thus improving the efficiency of template fixation;

[0027] And when fixing the template, templates with different diameter sizes can be fixed, so that the scope of use can be expanded and the practicability can be improved.

[0028] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
