Embodiment Construction

[0023] It should be noted that in this embodiment, the orientation words "top", "bottom", "left" and "right" are all described according to the drawings and do not constitute a limitation to the present invention.

[0024] Attached below Figure 1-3 The present invention is further described in detail: a grouting cover for making a load box steel bar connector standard test piece, such as figure 1 As shown, the grouting cover 100 is composed of a cover base plate 1, a cover enclosure 2, a reinforced pipe 3 and a grout tube 4; the cover base plate 1 and the cover enclosure 2 form a cylinder with an open end and a hollow inside, and the cover base plate 1 is a column The bottom plate of the body, the cover enclosure 2 is the side wall of the cylinder, and a hole is provided on the cover bottom plate 1 to allow the steel bar 6 to penetrate. 3 Corresponding to and connected to the hole position, the steel bar 6 is penetrated by the steel bar pipe 3 and the hole; a through hole is...

Abstract

The invention relates to part of structures for manufacturing standard test pieces of loading case steel bar connectors, in particular to a grouting cover and container for manufacturing a standard test piece of a loading case steel bar connector, wherein the grouting cover and the container are combined into a simulated loading case rigid connector. According to the grouting cover and the container for manufacturing the standard piece of the loading case steel bar connector, the grouting cover comprises a cover bottom plate and a cover enclosure; the cover bottom plate and the cover enclosureform a hollow cylinder with one end open; the cover bottom plate is the bottom plate of the cylinder and the cover enclosure is the side wall of the cylinder; a hole is formed in the cover bottom plate and is for a steel bar to penetrate; a through hole is formed in the cover enclosure; and the through hole serves as a channel for external grouting equipment to grout a test piece. The grouting cover and the container have the following advantages: 1. the practical quality effect assessment of existing loading case steel bar connector components after grouting is effectively solved; 2. the standard test piece produced is beneficial to grouting and use is convenient; 3. a cover body of the grouting cover is transparent, whether grouting meets technical requirements can be judged, and at thesame time a QR code is preset in production of the standard test piece to prevent replacement; and 4. the grouting cover and the container can be repeatedly used and cost is saved.

Description

technical field [0001] The invention relates to a partial structure for making a standard test piece of a load box steel bar connector, in particular to a grouting cover and a container for simulating a load box rigid connector. Background technique [0002] In the load box used in the self-balancing testing process of engineering piles, there are rigid connectors for the upper and lower bottom plates. After the self-balancing static load test of the engineering pile, grouting is performed on the inside and bottom of the sleeve of the rigid connector of the load box, so that the steel bars in the tube are held inside to form a rigid connection. However, the effect of grouting reinforcement cannot be verified. [0003] In order to verify the grouting reinforcement effect of rigid connectors, we made standard specimens of load box reinforced connectors according to actual working conditions, so that grouting samples can be sent for inspection after the balanced static load te...
