Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring construction, in particular to a template supporting device. Background Art

[0002] Concrete pouring construction is a key process in construction projects. It involves pouring mixed concrete into the formwork of a building structure. After pouring concrete into the pre-made structural formwork, the concrete will exert a large lateral force on the formwork. At the same time, during the pouring process, it is sometimes necessary to use a vibrating tool to vibrate and exhaust the concrete. The vibration of the vibrating tool also has a large vibration effect on the formwork. If the support stability of the structural formwork is insufficient, it will directly affect the concrete pouring process. At present, the support of the building structure formwork generally adopts the steel pipe rack for formwork support. Due to the large number of steel pipes required for the rack, the efficiency of the rack erection is low. At the same time, the efficiency of the later disassembly of the rack and the transportation of the steel pipes is also low. Furthermore, some assembled racks have appeared on the market. They can be used by simply assembling them at the construction site. However, the structural volume of the components of the assembled rack is not small, which makes it inconvenient to transport and carry them. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with specific embodiments and appendix Figure 1-6 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the embodiments described are only some preferred embodiments of the present invention, not all embodiments. Those skilled in the art may make similar modifications without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] The utility model provides a template support device (such as Figure 1The utility model is shown in Figure 1, comprising a horizontal positioning rod 1, a vertical support rod 2, and a telescopic adjustment rod 3. In actual application, the horizontal positioning rod 1 is used to be fixedly installed on the ground, and the vertical support rod 2 is used to support the outer side of the vertical formwork through the support of the horizontal positioning rod 1. The support of the vertical support rod 2 enables the formwork structure to resist the lateral force applied by pouring concrete. One end of the horizontal positioning rod 1 is hingedly connected to a section of the vertical support rod 2. Specifically, two mutually opposed hinged ears 12 are provided on one end of the horizontal positioning rod 1, and one end of the vertical support rod 2 is hingedly provided on the two hinged ears 12 through a pin shaft. In actual application, the folding and storage of the utility model can be achieved by rotating the vertical support rod 2 closer to the horizontal positioning rod 1; the opening of the utility model is achieved by rotating the vertical support rod 2 away from the horizontal positioning rod 1, thereby improving the use efficiency of the utility model; the lower end of the telescopic adjustment rod 3 is clamped in the inverted T-shaped groove 4 provided on the horizontal positioning rod 1, and the lower end of the telescopic adjustment rod 3 can be moved along The upper end of the telescopic adjustment rod 3 is clamped in the inverted T-shaped groove 4 provided on the vertical support rod 2, and the upper end of the telescopic adjustment rod 3 can slide and position along the length direction of the vertical support rod 2, and the telescopic adjustment rod 3 can be adjusted in length, so that the specific support position of the telescopic adjustment rod 3 on the horizontal positioning rod 1 and the vertical support rod 2 can be adjusted according to actual needs. The middle part of the telescopic adjustment rod 3 can be inserted into the corresponding inverted T-shaped groove 4. During the folding and storage process of the horizontal positioning rod 1 and the vertical support rod 2, as the folding degree continues, the telescopic adjustment rod 3 can be continuously inserted into the inverted T-shaped groove. When the horizontal positioning rod 1 and the vertical support rod 2 are completely folded parallel to each other, the telescopic adjustment rod 3 is hidden in the inverted T-shaped groove 4 in the horizontal positioning rod 1 and the vertical support rod 2, thereby greatly reducing the volume of the utility model after folding. The small volume facilitates the transfer and transportation of the utility model, thereby improving the transportation efficiency of the utility model.

[0023] In practical applications, to improve the stability of horizontal positioning rod 1 on the ground, a through hole 11 is provided in horizontal positioning rod 1, and said through hole 11 is adjacent to the hinged connection between horizontal positioning rod 1 and vertical support rod 2. During use, through hole 11 is inserted into the embedded bolts in the ground, and the nuts are used to press horizontal positioning rod 1 stably on the ground, thereby fixing horizontal positioning rod 1 to the ground and effectively preventing vertical support rod 2 from floating.

[0024] On the basis of the above embodiment, in order to facilitate the telescopic adjustment rod 3 to be completely hidden in the inverted T-shaped groove 4 after retraction, the original length of the telescopic adjustment rod 3 is made smaller than the length of the inverted T-shaped groove 4 set on the horizontal positioning rod 1 and the vertical support rod 2. For example, if the original length of the telescopic adjustment rod 3 is 2 meters, the length of the inverted T-shaped groove 4 is 2.4 meters.

[0025] On the basis of the above embodiment, the specific implementation of the telescopic adjustment rod 3 is as follows: the telescopic adjustment rod 3 includes an adjusting threaded rod 31, an adjusting sleeve 32, and a telescopic rod 33. An adjusting sleeve 32 is sleeved on both ends of the adjusting threaded rod 31. By rotating the adjusting threaded rod 31, the two adjusting sleeves 32 can be moved closer to or farther away from each other. The specific connection method between the adjusting threaded rod 31 and the two adjusting sleeves 32 can be designed with reference to the design structural features of the existing basket bolt. Therefore, the specific connection implementation method of the corresponding adjusting threaded rod 31 and the adjusting sleeve 32 will not be described in detail here. By rotating the adjusting threaded rod 31, the telescopic length of the telescopic adjustment rod 3 can be accurately adjusted. In order to facilitate the rotation of the adjusting threaded rod 31, a rotating socket 311 is provided in the middle of the adjusting threaded rod 31. By inserting a rod into the rotating socket 311, the rotation of the adjusting threaded rod 31 can be easily achieved. The other end of each adjusting sleeve 32 is sleeved with a telescopic rod 33. The telescopic rod 33 is relative to the corresponding The adjusting sleeve 32 can be slidably adjusted and positioned. The telescopic rod 33 slides relative to the adjusting sleeve 32, which facilitates the rapid adjustment of the telescopic length of the telescopic adjusting rod 3, and then facilitates the rapid initial adjustment and installation of the telescopic adjusting rod 3. In order to facilitate the rapid adjustment and positioning of the telescopic rod 33 in the adjusting sleeve 32, a positioning hole 321 is provided at the outer end of the adjusting sleeve 32, and a plurality of adjusting holes 332 corresponding to the positioning holes 321 are provided on the telescopic rod 33. A second pin shaft passes through the positioning hole 321. The telescopic rod 33 is positioned on the corresponding adjusting sleeve 32 in the positioning hole 321 and the corresponding adjusting hole 332; the outer diameter of the adjusting sleeve 32 is smaller than the upper opening width of the inverted T-shaped groove 4. In the structure of the adjusting threaded rod 31, the adjusting sleeve 32 and the telescopic rod 33, the outer diameter of the adjusting sleeve 32 is the largest. When the adjusting sleeve 32 can be inserted into the inverted T-shaped groove 4, the adjusting threaded rod 31 and the telescopic rod 33 can also be smoothly inserted into the inverted T-shaped groove 4, thereby making it easy to hide the entire telescopic adjusting rod 3 in the inverted T-shaped groove 4.

[0026] On the basis of the above embodiment, the specific implementation method of the end of the telescopic rod 33 being stuck in the inverted T-shaped groove 4 is as follows: a latch tube 331 is fixedly provided at the outer end of each telescopic rod 33, and the latch tube 331 is slidably sleeved in the corresponding inverted T-shaped groove 4. The length of the latch tube 331 is greater than the opening width of the inverted T-shaped groove 4, thereby ensuring that the latch tube 331 cannot be pulled out from the opening of the inverted T-shaped groove 4. In order to prevent the latch tube 331 from sliding out from both ends of the inverted T-shaped groove 4, a latch tube 331 can be fixedly provided at the outer end of each telescopic rod 33. The latch tube 331 is slidably sleeved in the corresponding inverted T-shaped groove 4. 4 is fixedly provided with a baffle at both ends, and a number of equally spaced latch holes 5 are provided on the horizontal positioning rod 1 and the vertical support rod 2 and pass through the corresponding inverted T-shaped slots 4. A first pin shaft 6 passes through the latch hole 5 and the latch tube 331 to realize the positioning of the corresponding latch tube 331 in the inverted T-shaped slot 4. When the ends of the two telescopic rods 331 are positioned on the horizontal positioning rod 1 or the vertical support rod 2 through a first pin shaft 6, it is convenient to use the telescopic adjustment rod 3 to support the vertical support rod 2 in the subsequent process.

[0027] In actual application, when the vertical support rod 2 is rotated to move away from the horizontal positioning rod 1, in order to prevent the vertical support rod 2 from rotating at an excessively large angle, a limit block 21 is provided at the hinge of the vertical support rod 2, and a limit boss 13 cooperating with the limit block 21 is provided on the horizontal positioning rod 1. The limit boss 13 is fixedly provided between the two hinged ears 12. When the limit block 21 is pressed against the limit boss 13, the vertical support rod 2 is placed vertically relative to the horizontal positioning rod 1.

[0028] In the present invention, "up", "down", "front", "back", "left" and "right" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0029] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0030] The above description, in conjunction with the accompanying drawings, details the preferred embodiments and examples of the present invention. However, the present invention is not limited to the above embodiments and examples. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the concept of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
