Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

Embodiment 1, as shown in fig. 1 to 4, this embodiment aims at providing a test mold capable of reducing test procedures and improving the concrete impermeability test efficiency, and for this reason, the novel impermeable test piece 4 set device provided by this embodiment includes a base 1 and a test mold arranged in cooperation with the base 1, and the above components are necessary parts for the test, and for this reason, the test piece 4 set device provided by this embodiment also includes the same, and for the purpose of quick test, the base 1 provided by this embodiment includes a base body 11 arranged in a disc shape and a fixing column 12 arranged in the middle of the base body 11, a water outlet 121 is arranged at the top of the fixing column 12, a water inlet 111 is arranged on the side wall of the base body 11, and the water inlet 111 and the water outlet 121 are arranged in a communicating manner. In this embodiment, compared with the conventional disc-shaped base 1, the main purpose of the fixing column 12 added in this embodiment is to place the test piece 4 above the fixing column 12, so that when the test piece 4 is sealed, the fixing column 12 can be kept sealed, thereby ensuring the sealing effect of the test piece 4, and for this purpose, a placement groove is provided at the top of the base body 11, and the placement groove is annularly arranged on the periphery of the fixing column 12.

Similarly, in order to achieve the purpose of rapid test, the test mold provided by the embodiment includes a cylindrical test mold housing 21 and a shaping sleeve 22 sleeved in the test mold housing 21, compared with the conventional test mold with a thicker wall thickness, the test mold provided by the embodiment only needs a thinner steel plate, and the main purpose of the test mold is to match the shaping sleeve 22.

In this embodiment, the test mold housing 21 and the shaping sleeve 22 are both tubular, the elastic tube sleeve 23 is arranged in the shaping sleeve 22, the elastic tube sleeve 23 is also tubular, and is made of rubber or elastic plastic, so as to inflate between the elastic tube sleeve 23 and the shaping sleeve 22, and the elastic tube sleeve 23 expands, so that the fitting test piece 4 is sealed, in order to seal between the elastic tube sleeve 23 and the shaping sleeve 22, the upper end and the lower end of the elastic tube sleeve 23 are bent and clamped between the test mold housing 21 and the shaping sleeve 22, in this embodiment, the thicknesses of the upper end and the lower end of the shaping sleeve 22 are smaller than the thickness of the middle, so that the fitting between the test mold housing 21 is ensured, and the elastic tube sleeve 23 is better clamped. In the embodiment, the structure that the elastic tube sleeve 23 is directly fixed on the shaping sleeve 22 is not adopted, mainly considering the service life of the elastic tube sleeve 23, the elastic tube sleeve 23 has the problem of replacement in the long-term inflation process, and for this reason, a separate structural design is adopted, so that only the elastic tube sleeve 23 needs to be replaced in the later period.

In order to inflate the elastic pipe sleeve 23, through holes are arranged on the shaping sleeve 22 and the test mold shell 21 in a matched mode, and an inflation pipe 24 is arranged in the through holes, so that the elastic pipe sleeve 23 is inflated.

Therefore, when the test is carried out, the test is firstly placed on the fixed column 12, then the assembled test mold sleeve is arranged on the fixed column 12, the fixed column 12 extends into the elastic pipe sleeve 23 to be arranged, then, the inflation is started, and the elastic pipe sleeve 23 wraps the fixed column 12 and the test piece 4, so that the sealing procedures are reduced, and the test efficiency is improved.

Of course, during the test, it is necessary to ensure the sealing arrangement between the base 1 and the test mold, that is, the relative fixation between the base 1 and the test mold, in this embodiment, a pressing manner is adopted, that is, a pressing mechanism is arranged above the test mold to realize the relative fixation between the base 1 and the test mold, and of course, the bolt-type fixation may also be adopted, and the pressing manner is preferred in view of the rapid test.

In order to further realize the fixation of the elastic pipe sleeve 23, in the embodiment, the height of the shaping sleeve is smaller than that of the trial mold housing 21, the top of the shaping sleeve 22 is provided with the press ring 3, and the press ring 3 is connected with the trial mold housing 21 through a bolt. Thus, the elastic pipe sleeve 23 is clamped by the pressing ring 3 at the upper part and clamped by the base 1 or the test mold shell 21 (a circle of supporting rings are arranged at the bottom of the test mold shell 21) at the lower part, so that the elastic pipe sleeve 23 is stably fixed. In consideration of the integrity of the test mold, it is preferable to provide a ring-shaped support ring structure at the bottom of the test mold housing 21 so as to serve as the bottom of the test mold housing 21, thereby fixing the elastic tube sleeve 23. In this way, the whole test mold housing 21 is formed into a whole, and the test mold housing can be taken up and down conveniently.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
