Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, in particular to a funnel for pouring structural columns. Background Art

[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. Commonly used concrete refers to cement as a cementitious material, sand and stone as aggregates; mixed with water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in the field of construction engineering.

[0003] Structural columns are set up to improve the seismic resistance of the masonry structure of multi-story buildings. The specifications require that structural columns should be set up at appropriate locations within the masonry of the house and connected to the ring beam to jointly enhance the stability of the building.

[0004] The existing concrete pouring funnel is suspended in the surrounding formwork of the structural column by a hoisting method during use. During the pouring process, the funnel may shake and become unstable due to the flow of concrete, resulting in concrete leakage and reduced pouring efficiency. Summary of the invention

[0005] In order to solve the problem that the existing funnel shakes during the pouring process and causes concrete leakage, the utility model proposes a funnel for pouring structural columns. The lower end of the funnel is first inserted into the surrounding template of the structural column, and then two first limiting rods and two second limiting rods are formed into a "mouth" shape and sleeved on the surrounding template of the structural column. Then, the size of the "mouth" is adjusted to fit closely to the surrounding template to fix the funnel, thereby improving the stability of the funnel during the pouring process.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A funnel for pouring a structural column comprises a fixed plate, the fixed plate is sleeved on the lower part of the funnel, two first limiting rods are relatively arranged below the fixed plate, a fixed rod is arranged between each of the first limiting rods and the fixed plate, the lower end of the fixed rod is fixedly connected to the first limiting rod, the upper end of the fixed rod is adjustable relative to the fixed plate to achieve the approach or distance of the two relatively arranged first limiting rods, two retractable second limiting rods are arranged between the two first limiting rods, the two first limiting rods and the two second limiting rods form a "mouth" shape, and the position of the second limiting rod relative to the first limiting rod is adjustable. The size of the "mouth" is adjusted by adjusting the fixed rod whose position is adjustable relative to the fixed plate and the second limiting rod whose position is adjustable relative to the first limiting rod to fit the tightly surrounding template of the structural column, so as to achieve the fixation of the funnel.

[0008] Further, a first through groove is formed in the fixing plate. The upper end of the fixing rod passes through the first through groove and is fixed with an extension part. A first bolt is threadedly connected to the extension part, and the first bolt passes through the extension part and abuts against the upper surface of the fixing plate. When the first bolt abuts against the fixing plate, the position of the fixing rod on the fixing plate is fixed. After loosening the first bolt, the position of the fixing rod on the fixing plate is adjustable.

[0009] Further, second through grooves and third through grooves are formed at both ends of each first limiting rod. The third through groove is located above the second through groove and penetrates the first limiting rod upward. The end parts of the two second limiting rods respectively extend into the corresponding second through grooves. A second bolt is inserted into the third through groove. The second bolt sequentially passes through the third through groove and the second limiting rod from top to bottom and then abuts against the lower surface of the second through groove. The second bolt is threadedly connected to the second limiting rod.

[0010] Further, the second limiting rod includes a telescopic rod and a hollow sleeve rod. The end part of the telescopic rod extends into the sleeve rod.

[0011] Further, a clamping part is fixed at one end of the sleeve rod close to the telescopic rod. The telescopic rod passes through the clamping part and then extends into the sleeve rod. A limiting plate is fixed at the end part of the telescopic rod extending into the sleeve rod. The clamping part is used for limiting the limiting plate. The cross-sectional area of the opening in the clamping part is the same as that of the telescopic rod, and the area of the limiting plate is larger than the area of the opening in the clamping part to limit the telescopic rod and prevent the telescopic rod from coming out of the sleeve rod during telescoping.

[0012] Further, the fixing rod is in a "Z" shape. Two symmetrical fixing rods are fixed on each first limiting rod to improve the stability of the first limiting rod.

[0013] Further, the funnel includes a feed pipe, a fixed cylinder and an extension cylinder. The feed pipe is in a horn shape. The fixed cylinder is fixedly connected to the lower end of the feed pipe. The extension cylinder is sleeved outside the fixed cylinder and is threadedly connected to the fixed cylinder. The fixing plate is sleeved on the lower part of the feed pipe.

[0014] By the above technical solution, the beneficial effects of the utility model are as follows:

[0015] 1. In the utility model, the position of the fixing rod on the first limiting rod relative to the fixing plate is adjustable, so that the distance between two opposite first limiting rods can be adjusted. Two telescopic second limiting rods are arranged between two opposite first limiting rods. The position of the second limiting rod relative to the first limiting rod is adjustable. The "square" formed by the two first limiting rods and the two second limiting rods tightly surrounds the formwork to fix the funnel, improving the stability of the funnel during pouring. By changing the size of the "square", it can adapt to construction columns of different sizes, improving the adaptation range of the device.

[0016] 2. In the utility model, the extension cylinder sleeved outside the fixed cylinder is threadedly connected to the fixed cylinder. After the funnel is used for a period of time, concrete is likely to solidify on the inner side of the funnel, resulting in blockage or slow flow rate of the funnel. At this time, the extension cylinder is removed from the fixed cylinder, facilitating the cleaning of the funnel. Description of the Drawings

Detailed Description of the Preferred Embodiments

[0023] The present utility model will be further described below in conjunction with the drawings and the detailed description of the preferred embodiments:

[0024] As Figures 1 to 5 shown, this embodiment provides a funnel for pouring construction columns, including a fixing plate 1. The fixing plate 1 is sleeved on the lower part of the funnel and welded to the funnel. In this embodiment, as Figure 5 shown, the funnel includes a feed pipe 14, a fixed cylinder 15 and an extension cylinder 16. The feed pipe 14 is in a flared shape. The fixed cylinder 15 is fixedly connected to the lower end of the feed pipe 14. The extension cylinder 16 is sleeved outside the fixed cylinder 15 and threadedly connected to the fixed cylinder 15; the extension cylinder 16 directly extends into the surrounding formwork of the construction column during use.

[0025] Furthermore, two first limiting rods 2 are oppositely arranged below the fixing plate 1. Between each first limiting rod 2 and the fixing plate 1, there are two symmetric "Z"-shaped fixing rods 3. The lower end of the fixing rod 3 is fixedly connected to the first limiting rod 2, and the upper end of the fixing rod 3 is adjustable relative to the position of the fixing plate 1 to realize the approach or separation of the two oppositely arranged first limiting rods 2.

[0026] Specifically, a first through groove 4 is formed on the fixing plate 1. After the upper end of the fixing rod 3 passes through the first through groove 4, an extension part 5 is fixed. A first bolt 6 is threadedly connected to the extension part 5, and the first bolt 6 passes through the extension part 5 and abuts against the upper surface of the fixing plate 1. In this embodiment, when the first bolt 6 abuts against the fixing plate 1, the position of the fixing rod 3 on the fixing plate 1 is fixed. After loosening the first bolt 6, the position of the fixing rod 3 on the fixing plate 1 is adjustable.

[0027] Furthermore, two telescopic second limiting rods are arranged between the two first limiting rods 2. The two first limiting rods 2 and the two second limiting rods form a "square" shape, and the position of the second limiting rods relative to the first limiting rods 2 is adjustable.

[0028] Specifically, second through grooves 7 and third through grooves 8 are formed at both ends of each first limiting rod 2. The third through groove 8 is located above the second through groove 7 and penetrates the first limiting rod 2 upward. The end parts of the two second limiting rods respectively extend into the corresponding second through grooves 7. A second bolt 9 is inserted through the third through groove 8. The second bolt 9 sequentially passes through the third through groove 8 and the second limiting rod from top to bottom and abuts against the lower surface of the second through groove 7. The second bolt 9 is threadedly connected to the second limiting rod. In this embodiment, after loosening the second bolts 9 at both ends of the second limiting rod, the end part of the second limiting rod can slide in the second through groove 7, and cooperate with the sliding of the fixing rod 3 on the fixing plate 1 to adjust the size of the "square".

[0029] As an implementable manner, the second limiting rod includes a telescopic rod 10 and a hollow sleeve rod 11. The end part of the telescopic rod 10 extends into the sleeve rod 11; a clamping part 12 is fixed at one end of the sleeve rod 11 close to the telescopic rod 10. The telescopic rod 10 passes through the clamping part 12 and then extends into the sleeve rod 11. A limiting plate 13 is fixed at the end part of the telescopic rod 10 extending into the sleeve rod 11. The clamping part 12 is used to limit the limiting plate 13. The opening in the clamping part 12 for the telescopic rod 10 to pass through has the same cross-sectional area as the telescopic rod 10, and the area of the limiting plate 13 is larger than the area of the opening in the clamping part 12 to limit the telescopic rod 10 and prevent the telescopic rod 10 from slipping out of the sleeve rod 11 during telescoping.

[0030] During use, first, the device is hoisted by a hoisting device and set at the upper end of the formwork surrounding the construction column. The extension tube 16 directly extends into the formwork surrounding the construction column, and the fixing plate 1 contacts the upper end of the formwork. Then, after loosening the first bolt 6, adjust the position of the fixing rod 3 on the fixing plate 1 so that the two first limiting rods 2 are attached to the outside of the formwork, and tighten the first bolt 6. At this time, loosen the second bolts 9 at both ends of the two second limiting rods, adjust the positions of the two second limiting rods on the first limiting rods 2 so that the two second limiting rods are attached to the outside of the formwork, and tighten the second bolts 9. At this time, the "square" formed by the two first limiting rods 2 and the two second limiting rods just wraps around the outside of the formwork, realizing the fixation of the funnel and improving the stability of the funnel during the pouring process of the construction column.

[0031] The above-described embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present invention patent should be included within the scope of the patent application of the present invention.
