Abstract

The utility model discloses a new impervious concrete die setting, which mainly comprises the die grid (1) and the mould bottom (2). The die grid (1) is connected with the mould bottom (2) via the bolt (3). The utility model is characterized in that a set of the lockup device is arranged at the contact surface of the die grid (1) and the mould bottom (2). This lockup device is composed of the projection (4) and the through hole (5). A set of projection (4) is equipped on the die grid (1). A set of through holes (5) are set on the mould bottom (2), so as to be correspond to the projection (4). Both the projection (4) and the through hole (5) form the lockup device, which is helpful for the connection between the die grid (1) and the mould bottom (2). This utility model features a simple structure, usableness and good impervious results. So, the quality of the test block is guaranteed.

Description

The impervious die trial of new concrete

Technical field

The utility model relates to die trial, is specifically related to the impervious die trial of new concrete.

Background technology

At present; the concrete impervious die trial of selling and using on the market; form removal is very difficult behind test block forming; the user often takes a lot of trouble for the smooth demoulding; in order to make the demoulding smoothly between test block after the moulding and the die trial; people mostly adopt form removal in advance or with the way of pressure testing machine with its separation; though removed the worry of the demoulding like this; but have to come off in the face of the test block edge; the ruined embarrassment in die trial base; and do like this and also do not meet national standard; because water-tight concrete has often added cement expansive material; volumetric expansion still can take place later in final set in concrete; and swelling agent only just can play the effect that makes concrete compaction under situation about being restricted; thereby reach impervious effect; this just needs the late as much as possible demoulding, and might be difficult to when doing infiltration test like this even can not load at all because concrete continues later on to expand in form removal.

Summary of the invention

The purpose of this utility model is: provide a kind of new concrete impervious die trial, make things convenient for test block to split from die trial, and can not damage test block and die trial itself, guarantee the impervious effect of test block.

Technical solution of the present utility model is: die trial mainly is made up of with at the bottom of the mould framed, framed by at the bottom of the bolt connection mode, it is characterized in that: establish one group of locking device at contact-making surface place framed and at the bottom of the mould, this locking device is made up of projection, through hole, on framed, establish one group of projection, with at the bottom of the mould of framed contact on corresponding projection establish one group of corresponding through hole, projection cooperate through hole constitute locking device auxiliary framed with being connected at the bottom of the mould.

During the dress mould, the projection and the through hole of locking device cooperatively interact, any change is not done in other operation, during form removal with after pulling down at the bottom of the mould, framed colliding surface gently removes module, perhaps with test block and framed being placed on together above the pressure testing machine, puts the resistance to compression backing plate above framed, do support by framed projection, the starting pressure testing machine just can be easily with test block and framed disengagement.

The utility model is simple in structure, and is easy to use, and the test block quality is guaranteed, and guarantees the impervious effect of test block.

Among the figure: 1. framed, 2. at the bottom of the mould, 3. bolt, 4. projection, 5. through hole, 6. handle.

The specific embodiment

As shown in Figure 1, die trial is mainly by 2 forming at the bottom of framed 1, the mould, framed 1 by at the bottom of bolt 3 connection modes 2, it is characterized in that: establish one group of locking device with 2 contact-making surface place at the bottom of the mould framed 1, this locking device is made up of projection 4, through hole 5, on framed 1, establish one group of projection 4, with one group of through hole 5 establishing corresponding projection 4 at the bottom of the mould of framed 1 contact on 2, projection 4 cooperates through holes 5 to constitute locking devices auxiliary framed 1 and 2 be connected at the bottom of the mould.

In the impervious die trial of new concrete of the present utility model, at framed outer periphery handle 6.

Claims

1. the impervious die trial of new concrete, die trial mainly is made up of (2) at the bottom of framed (1), the mould, framed (1) is by (2) at the bottom of bolt (3) connection mode, it is characterized in that: the contact-making surface place of (2) establishes one group of locking device at the bottom of framed (1) and mould, this locking device is made up of projection (4), through hole (5), on framed (1), establish one group of projection (4), with one group of through hole (5) of establishing corresponding projection (4) at the bottom of the mould of framed (1) contact on (2), projection (4) cooperates through hole (5) to constitute being connected of locking device auxiliary framed (1) and (2) at the bottom of the mould.
