Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a concrete chute. Background Art

[0002] At present, the main method of conveying concrete in concrete construction is to use automobile pumping or tower crane tanks. The common disadvantages of these traditional methods are that the middle part of the axis cannot be poured normally and the construction cost is high due to manual transfer, including the equipment foundation construction in the device, which is strictly restricted by the construction site. This method is suitable for small projects with small concrete volumes and a supplement to large-area frame pouring, but cannot meet the needs of large projects with large concrete volumes and relatively steep slopes. The use of chutes to pour concrete can greatly reduce the cost of using pump trucks to pour concrete, greatly save costs, eliminate the risk factor of using large machinery, use labor rationally, and improve production efficiency. However, most of the existing chutes are bolted to the bracket, which makes it inconvenient to disassemble and assemble the chute. For this reason, the inventor proposed a concrete chute.

[0032] Example 1

[0033] See also Figure 1-Figure 3 This embodiment provides a concrete chute to solve the problem of inconvenience in assembly and disassembly caused by bolting the existing chute to a bracket.

[0034] In this embodiment, the concrete chute includes a base 11 fixedly connected to the bottom of the chute 10, the base 11 defines a slot 111 for clamping the cross beam 21 on the bracket 20, a mounting seat 12 is provided inside the slot 11, a movable plate 121 is hinged on the mounting seat 12, a side wall of the movable plate 121 is provided with a slide groove 124, a pin 122 corresponding to the limiting hole on the cross beam 21 is inserted on the mounting seat 12, a limiting column 125 clamped with the slide groove 124 is provided on the pin 122, a spring 123 is provided between the mounting seat 12 and the movable plate 121, and the thrust of the spring 123 causes the outer end of the movable plate 121 to swing to the bottom of the mounting seat 12.

[0035] In this embodiment, the chute 10 is fixedly connected to the bracket 20 as a whole by the engagement of the cross beam 21 and the slot 111. The movable plate 121 designed in conjunction with the cross beam 21 swings under the pressure of the cross beam 21. The pin 122 can be inserted into the limit hole by the sliding engagement of the limit column 125 and the slide slot 124, so that the position of the base 11 on the cross beam 21 is fixed. The chute 10 can be removed from the bracket 20 as a whole by simply lifting it upwards, which has the advantage of being easy to use.

[0036] It should be noted that the chute 10 is arranged on the bracket 20 at an angle as a whole, and the chute 10 is constructed into an arc shape along the cross section. The base 11 is welded to the bottom surface of the chute 10. The base 11 includes two parallel side plates, and the two side plates are arranged perpendicular to the axis of the chute 10. The spacing between the two side plates forms a slot 111. As an example, the width of the slot 111 is equal to the outer diameter of the beam 21. The base 11 is arranged at each end of the chute 10, and the base 11 corresponds to the beam 21 on the bracket 20 one by one. Through the snap-fit ​​cooperation between the slot 111 and the beam 21, the chute 10 can be snap-fitted and fixed to the bracket 20 as a whole.

[0037] In addition, the mounting seat 12 is constructed as an inverted T-shape as a whole. The mounting seat 12 is welded between the inner side walls of the two side plates, so that the mounting seat 12 and the base 11 form an integrated structure. The movable plate 121 is symmetrically arranged on both sides of the mounting seat 12, and the rotation axis of the movable plate 121 is arranged perpendicularly to the side plates. The slide groove 124 extends along the longitudinal direction of the movable plate 121, the pin 122 is arranged perpendicularly to the rotation axis of the movable plate 121, and the pin 122 is arranged along the radial direction of the crossbeam 21. The limiting column 125 is arranged perpendicularly to the pin 122, the limiting column 125 can be slidably clamped in the slide groove 124, the pin 122 can be slidably inserted into the mounting seat 12 as a whole, and the spring 123 is fixed between the movable plate 121 and the mounting seat 12. The initial state In the state, under the elastic thrust of the spring 123, the outer end of the movable plate 121 swings to the bottom of the mounting seat 12, and the lower end of the pin 122 retreats into the interior of the mounting seat 12; after the chute 10 is installed on the crossbeam 21, the outer end of the movable plate 12 swings upward due to the push of the crossbeam 21, so that the spring 123 is compressed. At the same time, by using the sliding engagement of the limit column 125 and the slide groove 124, the pin 122 can be pushed toward the crossbeam 21 as a whole until the lower end of the pin 122 is inserted into the limit hole (not shown in the figure) on the crossbeam 21. By using the plug-in engagement of the pin 122 and the limit hole, the chute 10 can be prevented from moving along the axis of the crossbeam 21 as a whole, thereby ensuring that the installation position of the chute 10 on the bracket 20 is fixed.

[0038] When removing the chute 10 from the bracket 20, it is only necessary to lift the chute 10 upward as a whole. As the mounting seat 12 continues to move away from the cross beam 21, the movable plate 121 will be reset under the push of the spring 123, and the pin 122 will be driven to move upward, and finally the lower end of the pin 122 will be retracted into the mounting seat 12 again, and the chute 10 can be removed from the bracket 20.

[0039] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, substitute and modify the above embodiments within the scope of the present application.
