Abstract
The utility model provides a concrete durability test bores core sample support, includes bottom plate (1), brill core machine platform (2), test block fixed cardboard (3), cardboard fastener four bibliographic categories branch, wherein bore on core machine platform, the fixed cardboard of test block be fixed in the bottom plate respectively, offer slot (5) as the position of boring the core machine on boring core machine platform for remove the core machine that bores, cardboard fastener symmetry sets up in the fixed cardboard both sides of test block, cardboard fastener adopts spiral lead screw (4.2) of taking handle (4.1), is connected with the fastening at spiral lead screw (4.2) front end and takes over a business (4.3), is equipped with spiral lead screw (4.2) were established to the cover lead screw seat (4.4) on bottom plate (1). The utility model discloses an adjust two direction hobs and controller, and with the support of boring core machine platform, can realize the firm effect of test block.
Description
Technical field
The utility model relates to the core boring sampling bearing technical field in building operation.
Technical background
Core boring sampling bearing, be mainly used in concrete charge pass and chloride ion transport coefficient is tested (important indicator of concrete durability) test specimen and made, standard cube or the larger test block of size can be stablized, be conducive to boring core machine drill and get size core accurately.Current, at most of engineering field, concrete charge pass test and chloride ion transport ratio test are all important contents.And the size of test specimen has a significant effect to test findings, simultaneously test specimen side flatness not or run-off the straight, skew, the operability tested and accuracy will be unfavorable for.In actual tests, can compact dimensions be the right cylinder test block of Ф 100 × 100mm, and be tested by the part of cutting center section Ф 50mm.This kind of test specimen makes the requirement that can meet sample dimensions tolerance very well.And in Practical Project, because coarse aggregate size is bigger than normal, with the test block that this kind of cylinder mold is shaping, homogeneity of concrete is not being met, be also unfavorable for the actual conditions reflecting concrete works.And when boring core by standard cube of concrete test block, because fixing test cube do not considered by the brill core machine sold on the market.Therefore, in practical operation, be difficult to drill through size test specimen accurately.
Summary of the invention
The purpose of this utility model is just in order to overcome the defect that above-mentioned prior art exists and the concrete drill scheming sampling bearing providing a kind of and have good operability, can accurately drill through concrete core sample.
The purpose of this utility model is achieved through the following technical solutions:
A kind of concrete durability experiment core boring sampling bearing, comprises base plate, bores core machine platform, test block fixing chuck plate, clamp stationary installation four part; Wherein brill core machine platform, test block fixing chuck plate are individually fixed on base plate, brill core machine platform offers groove as the position of boring core machine, bores core machine for mobile; Clamp fastener is symmetricly set on test block fixing chuck plate both sides; Clamp fastener adopt band handle helical screw, be connected with in helical screw front end fastening take over a business, base plate is provided with the screw rodb base of sheathed helical screw.
The utility model is provided with bottom mobile device bottom base plate, adopts the universal wheel composition of four strap brakes.Base plate offers through hole adopts foot bolt, through through hole, base plate is fixed on ground.The utility model by fastening take over a business end face be set to zigzag plane.
The utility model can process the test specimen of 200 × 200 × 200mm, also can process the test block of 150 × 150 × 150mm; Vertical, smooth-going for its centre is drilled through; Be conducive to processing representative strong, size test block accurately.The utility model both can be fixed in laboratory, also can move to building-site and process.The utility model, by regulating both direction screw rod and controller, adds and the support of boring core machine platform, can realize the effect that test block is firm.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of concrete durability experiment core boring sampling bearing, comprises base plate 1, bores core machine platform 2, test block fixing chuck plate 3, clamp stationary installation four part; Wherein brill core machine platform 2, the fastening clamp 3 of test block are individually fixed on base plate 1, brill core machine platform 2 offers groove 5 as the position of boring core machine, bores core machine for mobile; Clamp fastener is symmetricly set on test block fixing chuck plate 3 both sides; Clamp fastener adopt band handle 4.1 helical screw 4.2, be connected with in helical screw 4.2 front end fastening take over a business 4.3, base plate 1 is provided with the screw rodb base 4.4 of sheathed helical screw 4.2.The utility model is provided with bottom mobile device 3 bottom base plate 1, adopts the universal wheel composition of four strap brakes.Base plate 1 offers through hole 1.1 adopt foot bolt to pass through hole 1.1 base plate 1 is fixed on ground.Fastening take over a business 4.3 end faces be set to zigzag plane.
The utility model should also be noted that following concrete operations:
1) test block fixing chuck plate and test block surface of contact are zigzag plane;
2) test block of core to be drilled is positioned over " test block platform and bore position "; Use spiral controller screwing bolts, fix test block;
3) regulate brill core machine, start to bore core work;
4) rest base has wheels, can move freely, and simultaneously when laboratory internal, can pass through base plate screw, fix with bolt.
