Description
Technical Field
The invention belongs to the technical field of civil engineering, and particularly relates to a large-size concrete test block pouring and demolding integrated mold and a using method thereof.
Background
In construction, the strength of concrete varies depending on the construction method, curing conditions, and the like of on-site concrete casting. In order to ensure the designed strength of concrete, the strength of concrete in the project needs to be checked. If the component is directly subjected to a load test, a load is added, and the component is pressed until the component is damaged, the difference between theoretical calculation and construction operation methods, maintenance conditions and the like is checked. This method is very intuitive and reliable. However, the problem with this method is that each time a component is used for testing, too much material is used: more importantly, some structural components are limited by conditions and cannot be directly tested. Such as beams, columns, foundations, caissons, walls, dams, piers, etc. of an industrial plant. The most economical and simple method in practice is to take out a part of the stirred concrete to be made into a plurality of groups of test blocks while pouring the concrete structure, and the strength of the constructed concrete is reflected by the test blocks.
When the concrete strength is detected, a mould is needed to process cube concrete test blocks with the side length of 100 mm-500 mm, and the test blocks are important marks for measuring the quality of concrete members. The existing adopted mould has the defect of difficult demoulding due to the fact that a single square plastic mould is adopted; also some moulds comprise 5 steel sheets, through bolted connection between the steel sheet, need assemble and dismantle the bolt when pouring and the drawing of patterns, not only waste time and energy, have the concrete to flow out between the steel sheet seam and cause the waste of material and the untidy in experimental place, the easy corrosion of bolt moreover causes the drawing of patterns difficulty.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides the large-size concrete test block pouring and demolding integrated mold which is simple in structure, convenient to operate, low in manual labor intensity and high in construction efficiency and the using method thereof.
In order to solve the technical problems, the invention adopts the following technical scheme: jumbo size concrete test block is pour and drawing of patterns integration mould, comprising a base plate, the bracing piece, box and layer board, the box is the open cuboid form in top, the bottom plate level sets up, the bracing piece is provided with a plurality of roots along the vertical direction, bracing piece lower extreme fixed connection is on the bottom plate, the round hole with bracing piece quantity box and upper and lower one-to-one is seted up to the bottom half, the layer board is the rectangle, the bottom of layer board setting in the box, the edge all around of layer board and box inside wall clearance fit all around, every bracing piece upper end corresponds and stretches into in the round hole, the external diameter of bracing piece is less than round hole diameter 1-5mm, bracing piece up end and layer board lower surface contact, the outside of every bracing piece all is provided with a set of support piece, every support.
Support piece is two structures and the equal same semicircle pipes of size, and the internal diameter more than or equal to of semicircle pipe is managed the external diameter of bracing piece, and the external diameter of semicircle pipe is greater than the diameter of round hole, and two semicircle pipe box are in the outside of bracing piece, and two semicircle outside of tubes correspond through the spring clamp and connect as an organic wholely, and the clamping part of spring clamp be with the arc structure of two semicircle pipe excircle adaptations.
The height of the supporting rod is greater than that of the box body.
The outer side part around the box body is provided with a handle.
Five support rods are arranged, wherein four support rods are respectively adjacent to four corners of the bottom of the box body, and the other support rod is positioned at the center of the bottom of the box body.
The application method of the large-size concrete test block pouring and demolding integrated mold comprises the following steps,
(1) sleeving the semicircular pipes outside the supporting rods, and clamping two adjacent semicircular pipes by using spring clamps;
(2) placing the supporting plate at the bottom in the box body, placing the box body at the upper end of the semicircular pipe, extending the upper end part of the supporting rod into the round hole to position the box body, and contacting the upper end surface of the supporting rod with the lower surface of the supporting plate;
(3) a release agent is coated on the inner side of the box body, then concrete is poured into the box body from an opening at the top of the box body, and the support rods and the ten semicircular pipes support the box body and the concrete in the box body together;
(4) curing the concrete according to a specified date;
(5) forming a concrete test block after the concrete test block reaches the standard through maintenance, taking down the spring clamp, removing the ten semicircular tubes, and supporting the concrete test block by the five support rods through the supporting plate;
(6) forcibly pressing the four handles downwards, vertically knocking the upper end edge of the vibrating box downwards, slowly moving the box downwards along the concrete test block until the concrete test block is separated from the box, and finishing demoulding operation;
(7) the concrete test block is moved off from the supporting plate;
(8) lifting the box body upwards along the five support rods and integrally moving the box body and the supporting plate down;
(9) and (5) repeating the steps (1) to (8).
By adopting the technical scheme, the box body is formed by welding six stainless steel plates, and the supporting plate is also made of the stainless steel plates.
Since the outer diameter of the semicircular tubes is larger than the diameter of the circular holes, the box body is supported by the ten semicircular tubes before concrete is poured. When the mould is poured, molded and maintained to be demoulded, firstly, the ten semicircular pipes are removed, the concrete test block on the upper part slightly moves under the action of gravity, the five support rods support the concrete test block through the supporting plates, and the box body is moved downwards to separate the concrete test block from the box body, so that the integrated operation of pouring and demoulding is realized.
In conclusion, the invention can realize the integrated operation of pouring and demoulding. The self gravity of the concrete is utilized to easily demould, so that the time required by demould is saved, and the labor is saved; the device is convenient to assemble and disassemble, saves concrete materials, is clean and tidy in test site, is simple to operate, has strong practicability, can be repeatedly used, and has wide application range.
