Description
Technical Field
The utility model relates to a survey fresh concrete slump technical field, specific portable concrete slump survey device that says so, it has the effect of conveniently carrying and easy and simple to handle when carrying out the fresh concrete slump test.
Background
The concrete slump is an important index for representing the mixing performance of fresh concrete and is an important basis for evaluating the plasticizing performance and pumpability of the concrete. The testing method comprises the steps of filling concrete into a horn-shaped slump bucket with an upper opening of 100mm, a lower opening of 200mm and a height of 300mm for three times, uniformly impacting 25 times along the wall of the bucket from outside to inside by using a tamping hammer after each filling, tamping and leveling. Then the barrel is pulled up, the concrete collapses due to self weight, and the height of the highest point of the concrete after collapse is subtracted by the barrel height (300 mm). The greater the slump, the better the plasticizing and pumpability properties are relative. The method has the advantages of simple operation and convenient application, and is widely applied in construction.
However, in the actual operation process, tools such as a steel plate, a slump cone, a tamping bar, a straight ruler, a spatula and the like need to be prepared for carrying out the concrete slump test, so that the test is quite trivial and inconvenient to carry out, and particularly, when the concrete slump test is carried out on a construction site, the site conditions are complex, a large number of tools need to be carried, the tools are easy to lose, and the test process is influenced.
Disclosure of Invention
In order to make things convenient for more to test, improve the portability of experimental facilities, the utility model provides a portable concrete slump survey device makes things convenient for experimental operation.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a portable concrete slump survey device, it includes steel sheet, slump section of thick bamboo, scraped surface horizontal pole triplex, the steel sheet is connected through articulated mode with the scraped surface horizontal pole.
Preferably, the steel plate is hinged with the shaving cross bar through a loose bolt or a loose rivet structure.
Preferably, the steel sheet is circular or square, and the central bilateral symmetry position leaves and is used for articulated connecting hole, and one side position leaves the level bubble, and four angular position installs leveling screw.
Preferably, the vertical height of the shaving cross bar is 300mm, a short hollow steel pipe is vertically welded at the center of the cross bar, the inner diameter of the short hollow steel pipe is larger than 16mm, and a handle is welded at the upper part of the cross bar.
Compared with the prior art, the utility model produced beneficial effect is:
when the concrete slump test is carried out, a complex tool does not need to be carried, so that the workload is greatly reduced, and the test is prevented from being influenced by the loss of the tool; meanwhile, the authenticity of test data is effectively improved, errors are reduced, the structure is simple, and the operation is convenient.
Drawings
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is a perspective view of the present invention.
In the figure, 1, a steel plate, 2, a slump cone, 3, a scraping cross bar, 11, connecting holes, 12, a horizontal bubble, 13, a leveling screw, 31, a hollow steel pipe and 32, a handle are shown.
Detailed Description
For better explanation of the present invention, the technical solution will now be further explained with reference to the specific embodiments and the drawings.
As shown in the attached figure 1, the utility model discloses a portable concrete slump survey device, its structure includes steel sheet 1, a slump section of thick bamboo 2, scraped surface horizontal pole 3.
The steel plate 1 is circular or square, connecting holes 11 are reserved in the edge positions of two sides of the center of the steel plate, the steel plate is connected with the scraping surface cross rod 2 in a hinged mode, two steel plates can rotate relatively, the horizontal bubble 12 is arranged in the edge position of the steel plate, and leveling screws 13 are respectively installed at four corners of the steel plate 1. The vertical distance between the shaving cross rod 2 and the center of the steel plate 1 is 300mm, a section of hollow short steel pipe 31 with the inner diameter slightly larger than 16mm is welded in the middle position, the tamper is just freely inserted and pulled out, and a handle 32 is arranged above the shaving cross rod 2.
When a concrete slump test is carried out, the steel plate 1 is placed at a relatively flat position, water bubbles in the horizontal bubbles 12 are located at the middle position by adjusting the leveling screws 13, the steel plate 1 is in a horizontal state, the test device is wetted according to test requirements, the slump bucket 2 is placed at the center position of the steel plate 1, after concrete is filled, the scraped surface cross rod 2 is rotated to scrape redundant concrete, the redundant concrete remained on the steel plate 1 is cleaned, the slump bucket 2 is slowly lifted, the scraped surface cross rod 2 is rotated to the position above the steel plate 1 vertically after the concrete does not flow, a tamper is inserted into the hollow short steel tube 31, and reading and recording are carried out. The whole test process is convenient and simple, and excessive tools do not need to be carried.
It should be noted that the language used in the specification has been principally selected for readability and instructional purposes, and may not have been selected to delineate or circumscribe the inventive subject matter. Accordingly, many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the appended claims. The disclosure of the present invention is intended to be illustrative, but not limiting, of the scope of the invention, which is set forth in the following claims.
