Description
[technical field]
The present invention relates to concrete test block maintenance, particularly relate to a kind of concrete briquette curing box.
[background technology]
While casting concrete structure, need from the concrete be stirred, to take out a part to do several groups of test blocks, to check the intensity of the xoncrete structure in construction by these test blocks.
In engineering construction, concrete test block has two kinds: one is standard maintaining test block (is called for short mark and supports test block), and another kind is maintaining test block with same condition.Mark is supported test block and is referred in standard conditions (temperature 20 ± 3 DEG C, relative humidity more than 90%, be divided into 3 days, 7 days and 28 days the length of time) under carry out maintenance after the test block that obtains, mark supports test block can check difference between the intensity of site mixed concrete and match ratio theoretical value.The test block that cured under same condition obtains after referring to and carry out maintenance under the condition that the condition of naturally hardening with xoncrete structure is identical, maintaining test block with same condition can check the difference between the actual strength of xoncrete structure and Structure Calculation theoretical value.By carrying out pressure testing to test block, the Strength Changes situation of xoncrete structure can be understood, thus determine the permission load etc. of the form removal of xoncrete structure, the time going out pond, lifting etc. and xoncrete structure.
Therefore, preparing concrete test block is at the construction field (site) requisite experimental project in construction.But when preparing mark and supporting test block, ready-made concrete test block may can not be delivered in time due to a variety of causes (such as just making test block before leaving offices) and carry out maintenance away from the standard curing room in the laboratory of job site, so these test blocks prepared will be deposited in job site, until the second talent is sent in standard curing room carry out maintenance.So just adverse influence is created to the quality of the foster test block of mark.
The utility model that the patent No. is CN201220074437.6 provides a kind of concrete briquette curing box, be provided with temperature and/or humidity control apparatus in this concrete briquette curing box, this temperature and/or humidity control apparatus are the open containers comprising water and at least one quick lime filter bag.In addition, described open containers can also have lid, to regulate the size of the opening of this open containers.This utility model and by regulating the size of opening of the quantity of water and quick lime and ratio, adjustment open containers, individually or jointly regulate the temperature and humidity in curing box, thus the mark forming concrete test block in curing box supports condition.This utility model adopts all-in-one-piece curing box structure, and capacious concrete curing box volume is too huge, and the job site for place anxiety is impracticable; This type of concrete curing box is due to too huge simultaneously, and the special crane gear of general needs carries out hoisting transportation.Therefore large-scale concrete curing box is settled and unrealistic in job site.And for capacious concrete briquette curing box, also must carry out constant temperature and humidity control to whole curing box inside when maintenance amount is little time, energy consumption is with substantially identical during its running at full capacity, and energy-saving effect is poor.The concrete curing box volume that volume is little is little, lightweight.But its volume is less, when carrying out casting of concrete in mass, need to make and a large amount of concrete test block of maintenance, now, the concrete briquette curing box that volume is little then seems scarce capacity.
