Description

Waterproof material performance measuring device corresponding to the behavior}

The present invention relates to a waterproof material performance measuring device corresponding to the behavior, and more specifically, to test the waterproof material coated on the concrete structure according to various environments and to obtain performance data for objective waterproof materials. It relates to a behavior test apparatus.

In general, civil structures are subjected to various forces due to their own weight, changes in groundwater level, and the flow of soil, and these displacement stresses cause serious problems such as deformation, collapse, or vibration of the structures.

Therefore, in order to economically and effectively design a structure with the necessary strength and function in accordance with the environment, various investigations, planning, research, design, analysis, and evaluation are performed.

For example, rainwater or groundwater may permeate because of lack of water tightness in concrete structures such as roof slabs, roofs, basements of buildings, and various fluid storage tanks.

In this case, the impregnated water not only decreases the bonding strength of the concrete itself, but also causes cracks in the concrete structure due to the change in the volume of water according to the temperature change, thereby shortening the life of the concrete structure.

Therefore, the waterproofing method of the concrete structure to prevent this is important, and the waterproofing material used in the waterproofing method should have proper performance and function.

The performance required for the waterproof material can be variously set according to the conditions required by the structure. Construction structures may degrade long-term waterproofing performance and durability due to salt environment, subsidence, cracking, etc.

Therefore, leaks in underground structures significantly damage the safety and usability of the entire structure, so a construction method that can ensure perfect waterproof quality in the design and construction stages should be introduced.

The performance regulations presented in the current KS standard are the minimum standards for material performance for each waterproof material, and do not guarantee proper performance in each situation. Most of the new technology waterproof materials currently used use a variety of materials in combination, and a waterproofing method using the same has been proposed, but there is a problem that an appropriate evaluation method has not been proposed for the proposed new technology waterproof material.

Currently, it is impossible to maintain a reliable and consistent quality level because it is selected by evaluating the waterproofing method according to different standards at each site.

Therefore, it is desirable to make sure that the waterproof material used in the waterproofing method of concrete structures has proper performance and function. That is, if there are test data on how much the concrete structure with the waterproof material endures under various environmental conditions that can be encountered in the real world, the design of the waterproof method of the actual concrete structure can be made economically and effectively.

The test method for responsiveness to the behavior of concrete structures against waterproof materials is as follows.

First, after attaching two mortar test specimens of a predetermined size simulating the shape of a concrete structure with a waterproof material (such as an adhesive or a joint), place them in a test chamber, and then, under temperature conditions (eg, room temperature 20±3℃ and low temperature − 10±2℃) and fresh water condition (filling the water in the test chamber), and then conduct the behavior test.

The behavior test is, for example, by setting the behavior width to 4.5 mm (tolerance ±0.2 mm) and the behavior speed of 5 m/min, to behave the specimen approximately 100 times. As a result, it is checked whether water leaks into the test body.

However, since a dedicated test device for a concrete structure is not provided in the related art, it is impossible to obtain an accurate and objective test result, so it is impossible to secure public confidence and reliability in the test result. Accordingly, the present inventor has proposed a structure behavioral responsiveness test apparatus for a waterproofing material disclosed in Korean Patent No. 10-1465943 and a test method for responsiveness of a waterproofing material according to the testing apparatus.

However, in the behavior test of the above-described test apparatus, there is a limitation that the behavior test of the test body applies only a tensile force in a simple direction.

That is, in reality, there is still a need for an improved test apparatus capable of setting the behavior test conditions closer to reality because tensile forces can be applied to structures in various directions.

In addition, Patent Application No. 10-1671781 filed to overcome the above problems discloses a composite behavior test apparatus and method for performance testing of waterproof materials corresponding to an external environment.

However, in the complex behavior test apparatus and method for the performance test of waterproof materials corresponding to the external environment, there is a shortage in obtaining detailed operation and data in the vertical direction and the left and right direction, so it is necessary to supplement this.

For example, the temperature condition is set to 20±3° C. at room temperature and −10±2° C. to low temperature, and the fresh water condition is set such that the test body 10 is submerged by introducing fresh water into the test chamber 200.

Next, by selecting the up and down tension force, horizontal tension force, left and right twisting force with respect to the test object 10 using the up and down repetition operation part 320, the left and right horizontal operation part 340, the front and rear operation part 360 Operate sequentially.

For example, the up-and-down repetition operation unit 320 sets the up-and-down oscillation width to 4.5 mm (tolerance error ±0.2 mm) and a vibration speed of 5 m/min to vibrate the test body about 100 times or more, and the front-rear operation unit (360) is set to the left and right vibration width 2.5 mm (tolerance ±0.1 mm), the vibration speed of 2 m / min, it is possible to twist the specimen repeatedly from side to side.

Then, the leak detection sensor 460 is used to detect a leak in the leak path 420, and if a leak occurs in the leak path 420, the behavior test step may be stopped and test data may be prepared. At this time, water moving along the leak path 420 is collected in the drain tank 460.

The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments and can be modified or modified in various forms, and the modified or modified embodiments are also disclosed in the following claims. Of course, if it includes the technical idea of belonging to the scope of the present invention.
