Abstract

The utility model relates to a columnar concrete-like material molding device. The columnar concrete-like material molding device comprises a pouring mold which is of a tubular structure on the whole, wherein the pouring mold is divided into an upper semi-circular mold and a lower semi-circular mold by taking a center line as a base point, and the upper mold and the lower mold are identical in structure and are connected with each other. The columnar concrete-like material molding device is light in dead load and easy to assemble and disassemble and can be used for greatly alleviating the amount of testing labor and saving manpower. In addition, the columnar concrete-like material molding device comprises few assembly parts, is reasonable in size and length, and can be used for effectively improving the uniformity of concrete test blocks, so that the purpose of improving the testing accuracy is achieved.

Description

Concrete Material column shaped device

Technical field

The utility model relates to a kind of Concrete Material column shaped device.

Background technology

Separate type Hopkinson (Hopkinson) pressure bar system testing equipment is one of topmost research technique in research material dynamic mechanical experimental series.This equipment is mainly used in plain concrete, fiber concrete, reaches the dynamic mechanical experimental study of other all kinds of concrete materials.

Test the working (machining) efficiency of concrete test block used and make quality, directly determining the progress of test and the validity and reliability of test figure.

At first, the existing concrete charge bar is built mould and is existed from shortcomings such as great, assembling and unloading process very complicateds, makes the operations such as building, vibrate of concrete test block expend a large amount of manpowers and time, affect test efficiency, restricts the test process;

Secondly, the existing mold longer dimension, when concrete mix injects mould, drop is larger, after the shaking table vibration, is prone to segregation, affects the homogeneity of concrete test block, and the objectivity of test findings is had a greatly reduced quality;

Finally, because existing mold is 4 part assembly types, the charge bar surface irregularity after the demoulding, for the operations such as the cutting of later stage charge bar, polishing have increased unnecessary difficulty and workload.

The utility model content

Technical problem to be solved in the utility model is to provide the charge bar in a kind of mould easily to come off, and the charge bar surfacing after the demoulding, later stage be a kind of like this Concrete Material column shaped device of processing easily.

The technical scheme that realizes above-mentioned purpose is as follows:

Concrete Material column shaped device, it is characterized in that: comprise the mould of building that substantially is a tubular structure, described build mould take center line as basic point round in two, be respectively upper die and lower die, patrix is identical with lower die structure and connect, offer at least one and split hole on the axial free-ended tube wall of patrix, counterdie also has lower fractionation hole on corresponding position, after upper die and lower die are connected to form complete tubular structure, upper fractionation hole and lower fractionation hole also form a complete fractionation hole.Build the column structure of the preferred hollow of mould.

Further, described fractionation hole is circular, and upper fractionation hole and lower fractionation hole are semi-circular structure.

Further, also comprise at least one tight loop, described tight loop is socketed on the excircle of building mould, the internal diameter of tight loop and the external diameter adaptation of building mould.

Further, described tight loop is three, and one of them is socketed in the centre of building mould, and another two are socketed in respectively the two ends of building mould.

Tight loop also can arrange one or more than three.

Further, a described end of building mould is connected with base, and base is blocked the center pit of building mould.

The length of further, building mould is 820 millimeters.

The using method of Concrete Material column shaped device: at first the upper die and lower die of building mould are integrally combined, use tight loop will build the mould banding; Next cast thing injects builds in mould;

Finally, after waiting for mould molding, take down tight loop, utilize splitting tool to insert to split hole to open and build mould, make it to resolve into upper die and lower die, the mould moulding that comes off.

This device is simple from heavy and light, assembling and dismounting, has greatly alleviated the test labor capacity, has saved manpower.In addition, because this device assembling parts is few, dimensions length is reasonable, can effectively improve the homogeneity of concrete test block, thereby reach the purpose that improves test accuracy.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

Concrete Material column shaped device, the mould of building that comprises a tubular structure, described build mould take center line as basic point round in two, be respectively patrix 1, counterdie 2, patrix is identical with lower die structure and connect, build on mould and offer fractionation hole 3, the effect that splits hole is the separation that facilitates upper die and lower die after cement is built moulding.Offer at least one and split hole on the axial free-ended tube wall of patrix, counterdie also has lower fractionation hole on corresponding position, and after upper die and lower die are connected to form complete tubular structure, upper fractionation hole and lower fractionation hole also form a complete fractionation hole.Split hole circular structure, manufacture simple.

For by patrix 1, it is tight that counterdie 2 is fixed, tight loop 4 is set building on mould, tight loop 4 can arrange one or several, can be arranged on and build in the middle of mould, also can arrange respectively at the two of building mould, preferred in the centre of building mould in the utility model, tight loop 4 is designed respectively at two, tight loop is socketed on the excircle of building mould, the internal diameter of tight loop and the external diameter adaptation of building mould, one end of building mould is connected with base 5, base is blocked the center pit of building mould, prevent that the cement of building from exposing, on base, handle can also be set.

The mould inner surface of building of tubular structure requires smooth and flatness good, be convenient to the demoulding, and the quality of the mold outer surface produced is good, easily cleaning, polishing.

In order to reduce deadweight, build preferably 820 millimeters of the length of mould.

These are only the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; all within the spirit and principle of the utility model embodiment; any modification of doing, be equal to replacement, improvement etc., all should be included in the protection domain of the utility model embodiment.
