Embodiment 1

[0021] Please refer to image 3 , in this embodiment, the adjustment frame 2-1 is provided with 5 installation holes, the operator chooses the second installation hole from the left, and the operator can arbitrarily choose an angle according to his own behavior habits. Mounting holes are used to match the handle 1 with the adjustment frame 2-1.

Embodiment 2

[0023] Please refer to Figure 4 , in this embodiment, only one installation hole is provided on the adjustment frame 2-1, and the operator can adjust the angle of the handle according to his own working habits during the actual operation process. In fact, In this case, the selection range of the angle adjustment that the operator can perform is larger.

[0024] In any state of use, the operator can adjust the length of the handle 1 .

[0025] Preferably, the distance between the connecting protrusion 1 - 1 and the lower end surface of the handle 1 is 1 / 8-1 / 7 of the length of the handle 1 .

[0026] Preferably, the lower end surface of the handle 1 is a curved surface.

[0027] Preferably, a gasket is provided between the connection protrusion 1-1 and the installation hole 2-2.

[0028] Preferably, the length of the flat pushing portion 2-3 is 1 / 4-1 / 3 of the length of the plate 2.

Abstract

The invention relates to a concrete pushing plate. The concrete pushing plate comprises a handle, a plate part and roller shafts. The handle is in a slender shape and can be expanded and contracted, and two connecting bulges which are arranged symmetrically are formed in the lower end surface, close to the handle, of the concrete pushing plate. Each connecting bulge is provided with an external thread. The shape of the side surface of the plate part is of a T-shaped structure, the upper end surface of the plate part is rectangular, and two semicircular adjusting frames which are symmetrical with respect to the central line of the long edge of the plate part are arranged on the upper end surface of the plate part. More than one mounting holes are formed in each adjusting frame. The handle is connected with the plate part through matching of the connecting bulges and the mounting holes. The middle of the lower end surface of the plate part is provided with a horizontally-pushing part. The more than one roller shafts which are fixed on the lower end surface of the plate part are arranged at the left end and the right end of the horizontally-pushing part. Therefore, the concrete pushing plate is convenient to operate, an angle is adjusted conveniently, and the labor intensity of workers is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of concrete, in particular to a concrete push plate. Background technique [0002] If there is large-volume concrete construction on the construction site, construction workers usually need to initially scrape the poured concrete with a water length scraper within 3 to 4 hours after pouring, and then roll it twice with an iron trowel before initial setting , and then use a wooden trowel to compact it to control surface cracks, and cover and maintain according to the regulations; but the ordinary scraping ruler makes the construction personnel work for a long time, and the quality and effect of the product are relatively poor. To solve this problem, patent ZL 201020255762.3 discloses a concrete push plate. It consists of a plate connected to a push rod by connecting means. Compared with the prior art, the present invention adopting the above-mentioned technical solution can not only increase the smoothness ...
