Description

Technical Field

[0001] This utility model relates to the field of building sampling technology, specifically to a building engineering witness sampling device. Background Technology

[0002] The witnessed sampling and testing system refers to a procedure in which, under the witness of the construction supervision unit or the construction unit, the construction unit's full-time material testing personnel take samples or make test specimens on-site for relevant building materials entering the construction site and send them to a laboratory that meets the qualification management requirements for testing.

[0003] Concrete sampling is part of witnessed sampling. Concrete samples need to be made into concrete test blocks on site. The concrete test blocks used for compressive strength testing are cubes with a side length of 15 cm. There are also cubes with a side length of 10 cm and cubes with a side length of 20 cm. Concrete test molds are needed for making them. The existing concrete test molds are square tubes made of metal. They are large and inconvenient to carry. In addition, they can only make concrete test blocks of one size. They need to be improved. Utility Model Content

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0017] Combined with appendix Figure 1-4 A construction engineering witness sampling device includes a concrete mold 2 formed by interlocking test mold parts 1, wherein the test mold parts 1 include a first plate 3 and a second plate 4 that are hinged to each other. The bottom of the first plate 3 and the second plate 4 are provided with several notches 5 that are inserted and matched with the test mold 1; Both the first plate 3 and the second plate 4 have a limiting strip 6 on their outer sides that cooperates with the notch 5.

[0018] In use, place one mold 1 on the ground with its notch 5 facing upwards, and the first plate 3 and the second plate 4 at a 90-degree angle. Unfold the second mold 1, with the first plate 3 and the second plate 4 at a 90-degree angle and the notch 5 facing downwards. According to the specifications of the concrete mold 2 to be made, interlock the corresponding notches so that the bottom of the second mold 1 is in contact with the ground. The limiting piece 6 can prevent the concrete mold 2 from opening and deforming when filling it with concrete. After use, tap the mold 1 to separate it from the concrete test block and remove the mold 1. Example 2

[0019] Combined with appendix Figure 4 A first cylinder 7 is fixedly provided on one side of the first plate 3, and a second cylinder 8 is fixedly provided on one side of the second plate 4, which is symmetrically arranged and cooperates with the first cylinder 7.
