Description

Technical Field

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

[0002] Concrete casting formwork refers to the formwork for newly poured concrete and a complete set of structural systems that support the formwork. In the concrete pouring process, the formwork plays a vital role. It can not only support the dead weight of the concrete and the lateral pressure during the pouring process, ensure the accurate pouring and curing of the concrete, but also bear the load of personnel, equipment and materials, and ensure the stability and safety of the construction. When using the formwork for pouring, this pouring method of pouring layer by layer is called the layered concrete pouring method. The concrete is delivered by a pump and then compacted with a vibrator. Layered concrete pouring helps ensure that each layer of concrete can evenly and tightly fill the formwork, reduce voids and defects in the concrete, and at the same time, it also helps to control the heat and shrinkage of the concrete and reduce the occurrence of cracks.

[0003] During the pouring process, it is important to note that the height of the pouring layer should be determined based on the concrete supply capacity, the volume of one-time pouring, the initial setting time of concrete, the structural characteristics, and the density of the steel bars. The pouring of concrete should be carried out in sections and layers continuously. If it is necessary to pause, the pause time should be shortened as much as possible, and the second layer of concrete should be poured before the initial setting of the previous layer of concrete. When using layered pouring, the forces on the formwork are different. When pouring the first layer, the concrete is condensed at the bottom of the formwork, and there is almost no force on the top of the formwork. When the force is increased layer by layer, the force on the formwork is also increasing layer by layer, so the force points of the support device used for the formwork are also different.

[0004] Traditional support devices are often fixed, fixed to the formwork and the ground with screws, and are difficult to change according to the change of the support point. Because a large number of screws are used, it is difficult to disassemble and change the force point, resulting in the support device being unable to reasonably share the pressure on the formwork, which may cause damage to the formwork during layered pouring, and it is difficult to disassemble after the concrete dries, resulting in increased workload and extended construction period. Therefore, it is necessary to propose a concrete pouring formwork support device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides Figure 1 - Figure 8 A concrete casting formwork support device shown in the figure includes a first U-shaped plate 1, a second U-shaped plate 2 is clamped inside the first U-shaped plate 1, one end of the second U-shaped plate 2 is hinged to the end of the first U-shaped plate 1, a third U-shaped plate 3 is clamped inside the end of the second U-shaped plate 2 away from the first U-shaped plate 1, a support rod 4 is clamped inside the end of the first U-shaped plate 1 away from the second U-shaped plate 2, and the end of the support rod 4 away from the first U-shaped plate 1 is hinged inside the end of the third U-shaped plate 3 away from the second U-shaped plate 2.

[0029] In actual use, the second U-shaped plate 2 can rotate around the end of the first U-shaped plate 1, and the length of the second U-shaped plate 2 is smaller than the length of the first U-shaped plate 1, so that the second U-shaped plate 2 can rotate into the interior of the first U-shaped plate 1, and the width of the third U-shaped plate 3 is smaller than the inner circle width of the second U-shaped plate 2, so that the third U-shaped plate 3 can be inserted into the interior of the second U-shaped plate 2, and the width of the support rod 4 is smaller than the inner circle width of the third U-shaped plate 3, so the support rod 4 can enter the interior of the third U-shaped plate 3 when it is stored. During installation, use screws to fix the second U-shaped plate 2 to the template, and use screws to fix the first U-shaped plate 1 to the ground.

[0030] Because a large number of formworks are needed when pouring concrete, a large number of supporting devices are needed to support the formworks. Traditional supporting devices are mostly made of steel plates. This results in the supporting devices taking up a lot of space during transportation, and they need to be spliced ​​each time they are used. The process is cumbersome and the disassembly and assembly are complicated.

[0031] Therefore, the device is provided with a first U-shaped plate 1 and a second U-shaped plate 2, so that when it is not in use, it only needs to rotate the second U-shaped plate 2 to rotate it to the inside of the first U-shaped plate 1, and at the same time the third U-shaped plate 3 and the support rod 4 will also be bent, and the support rod 4 will enter the inside of the third U-shaped plate 3 to achieve storage. The device after storage is only the volume of an angle iron, which can save a lot of space during transportation, reduce the complexity of disassembly and assembly, and improve practicality.

[0032] Two symmetrical second shells 21 are fixedly installed inside the second U-shaped plate 2, and a second T-shaped groove 22 is opened inside the second shell 21. The first shell 11 is fixedly installed on both sides of the first U-shaped plate 1, and a first T-shaped groove 12 is opened inside the first shell 11. First sliding components 31 are rotatably installed on both sides of one end of the third U-shaped plate 3 close to the second U-shaped plate 2, and a connecting shaft 42 is fixedly installed on one end of the support rod 4 close to the first U-shaped plate 1, and second sliding components 43 are rotatably installed on both sides of the connecting shaft 42. The first sliding component 31 is slidably clamped in the second T-shaped groove 22, and the second sliding component 43 is slidably clamped in the first T-shaped groove 12. The first sliding component 31 and the second sliding component 43 both include a connecting rod 311, and a bracket 312 is rotatably installed on one side of the connecting rod 311, and pulleys 313 are rotatably installed on the four supporting feet of the bracket 312.

[0033] When in use, because the first sliding component 31 is slidably clamped inside the second U-shaped groove 22, the third U-shaped plate 3 can slide along the second U-shaped plate 2, and the second sliding component 43 is slidably clamped inside the first T-shaped groove 12, the support rod 4 can slide along the first U-shaped plate 1, so that the total length of the third U-shaped plate 3 and the support rod 4 can be changed. When the total length of the third U-shaped plate 3 and the support rod 4 is changed, because the first U-shaped plate 1 and the second U-shaped plate 2 are perpendicular, it can be known according to the Pythagorean theorem that the support point positions of the third U-shaped plate 3 and the support rod 4 will also change accordingly, which is convenient for changing the support point positions according to the concrete position inside the mold. The pulley 313 can reduce the friction during sliding, making the sliding more stable, or the length of the third U-shaped plate 3 and the support rod 4 is fixed, so that the end of the third U-shaped plate 3 and the end of the support rod 4 slide on the second U-shaped plate 2 and the first U-shaped plate 1 respectively, thereby changing their force points.

[0034] A plurality of evenly distributed first slots 13 are provided on the side walls of the two first shells 11, a plurality of evenly distributed second slots 14 are provided on the inner bottom surface of the first U-shaped plate 1, the first slot 13 is connected to the interior of the first T-shaped slide 12, a plurality of evenly distributed fourth slots 24 are provided on the inner walls on both sides of the second U-shaped plate 2, a plurality of evenly distributed third slots 23 are provided on the inner top surface of the second U-shaped plate 2, a second center slot 25 is provided on both side walls of one end of the second U-shaped plate 2 close to the first U-shaped plate 1, a first center slot 15 is provided on both side walls of one end of the first U-shaped plate 1 close to the second U-shaped plate 2, the first center slot 15 and the second center slot 25 are located on the same axis, the fourth slot 24 is connected to the interior of the second T-shaped slide 22, a sixth slot 41 is provided on one end of the support rod 4 close to the third U-shaped plate 3, and a plurality of evenly distributed fifth slots 32 are provided on both side walls of the third U-shaped plate 3.

[0035] After sliding the third U-shaped plate 3 and the support rod 4 to the appropriate position, use screws to screw into the corresponding fourth slot body 24 and the first slot body 13, tighten the second sliding component 43 and the first sliding component 31 to make them unable to move, thereby achieving the support effect. The third slot body 23 and the second slot body 14 are both used to install screws to fix the second U-shaped plate 2 to the template, and the first U-shaped plate 1 is fixed to the ground. When the length of the third U-shaped plate 3 and the support rod 4 is determined, use screws to pass through the corresponding fifth slot body 32 and screw into the sixth slot body 41 to fix the total length of the third U-shaped plate 3 and the support rod 4.

[0036] The second center groove 25 is rotatably clamped with a center axis 53 inside, the first center groove 15 is rotatably sleeved on the outer surface of the center axis 53, and a support cylinder 5 is fixedly installed on the outside of the center axis 53. The support cylinder 5 is located between the angles between the first U-shaped plate 1 and the second U-shaped plate 2, and the support block 52 is against the lower surface of the third U-shaped plate 3. The end of the support cylinder 5 away from the center axis 53 is clamped with a lifting screw 51 through a threaded fitting, and the end of the lifting screw 51 away from the support cylinder 5 is fixedly installed with a support block 52.

[0037] Because during use, the connection between the third U-shaped plate 3 and the support rod 4 is easily bent due to the pressure load, and then when the third U-shaped plate 3 and the support rod 4 are installed, the lifting screw 51 is rotated to increase the total length of the support cylinder 5 and the lifting screw 51 until the support block 52 is against the lower surface of the third U-shaped plate 3 or the support rod 4. Because the central axis 53 can rotate around the axis, no matter what the installation position and installation height of the third U-shaped plate 3 and the support rod 4 are, the lifting screw 51 can be perpendicular to the third U-shaped plate 3 and the support rod 4, thereby producing the best supporting effect for the third U-shaped plate 3 and the support rod 4.

[0038] Working principle: During installation, use screws to fix the second U-shaped plate 2 on the template, and use screws to fix the first U-shaped plate 1 on the ground. The third U-shaped plate 3 can slide along the second U-shaped plate 2, and the support rod 4 can slide along the first U-shaped plate 1, so that the total length of the third U-shaped plate 3 and the support rod 4 can be changed. When the total length of the third U-shaped plate 3 and the support rod 4 is changed, because the first U-shaped plate 1 and the second U-shaped plate 2 are perpendicular, the support point positions of the third U-shaped plate 3 and the support rod 4 on the first U-shaped plate 1 and the second U-shaped plate 2 will also change accordingly. The pulley 313 can reduce the friction during sliding, making the sliding more stable, or fix the length of the third U-shaped plate 3 and the support rod 4, so that the ends of the third U-shaped plate 3 and the ends of the support rod 4 slide on the second U-shaped plate 2 and the first U-shaped plate 1 respectively, thereby changing their force points.

[0039] After sliding the third U-shaped plate 3 and the support rod 4 to the appropriate position, use screws to screw into the corresponding fourth slot body 24 and the first slot body 13, tighten the second sliding component 43 and the first sliding component 31 to make them unable to move, thereby achieving the support effect, fix the second U-shaped plate 2 to the template, and fix the first U-shaped plate 1 to the ground. When the length of the third U-shaped plate 3 and the support rod 4 is determined, use screws to pass through the corresponding fifth slot body 32 and screw into the sixth slot body 41 to fix the total length of the third U-shaped plate 3 and the support rod 4.

[0040] During use, the connection between the third U-shaped plate 3 and the support rod 4 is easily bent due to the pressure load. When the third U-shaped plate 3 and the support rod 4 are installed, the lifting screw 51 is rotated to increase the total length of the support cylinder 5 and the lifting screw 51 until the support block 52 is against the lower surface of the third U-shaped plate 3 or the support rod 4. Because the central axis 53 can rotate around the axis, no matter what the installation position and installation height of the third U-shaped plate 3 and the support rod 4 are, the lifting screw 51 can be perpendicular to the third U-shaped plate 3 and the support rod 4, thereby producing the best supporting effect for the third U-shaped plate 3 and the support rod 4.

[0041] When storing, the second U-shaped plate 2 is rotated into the interior of the first U-shaped plate 1, and at the same time, the support rod 4 is also rotated into the interior of the third U-shaped plate 3, so that the entire device is stored to form a rod body.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
