Abstract

The utility model relates to a concrete specimen curing frame, which consists of a bracket and a transverse plate, wherein the bracket comprises a plurality of vertical brackets and a plurality of transverse brackets to form a curing frame framework; and each layer of transverse bracket is provided with a transverse plate which is made of a material difficult to corrode and is provided with a threaded hole for mounting a cushion block. The cushion block comprises a rubber pad and a T-shaped cylinder. The rubber pad is fixed on the upper surface of the T-shaped cylinder, and the rubber pad plays a role in reducing the acting force of the T-shaped cylinder on the concrete test piece and playing a role in buffering; the lower end of the T-shaped cylinder is provided with threads for mounting the cushion block on the transverse plate; and the four adjacent cushion blocks are in a group and are connected into a square, and a concrete test piece can be placed. In the utility model, the transverse plate is a complete plate, and accumulated water cannot drop onto a lower-layer concrete test piece; the cushion block heightens the concrete test piece, so that the bottom surface of the concrete test piece is better maintained in a standard way and is not washed by running water.

Description

Concrete test piece maintenance frame

Technical Field

The utility model belongs to the technical field of concrete engineering, and particularly relates to a concrete sample maintenance frame.

Background

At present, a maintenance frame used for concrete maintenance always has the condition that a concrete test piece is eroded by water dripping or flowing water, and no effective measure is provided for avoiding the situation.

The maintenance frame that uses now does not have unified standard, for example welds with the channel-section steel, and two horizontal channel-sections are a set of, can place a set of concrete test piece, but the steel bay has certain ponding. The accumulated water in the upper layer can drop on the concrete test piece in the lower layer to erode the concrete test piece; when the porous plate is used, the concrete test piece can be placed on the porous plate, but the porous plate can also have accumulated water, and the accumulated water falls onto the concrete test piece on the lower layer through the hole to erode the concrete test piece.

Disclosure of Invention

The utility model aims to provide a concrete specimen curing frame.

In order to realize the task, the technical scheme provided by the utility model is as follows:

a concrete specimen curing frame consists of a support and transverse plates, wherein the support comprises a plurality of vertical supports and a plurality of transverse supports which are connected in pairs to form a frame structure, so that a stable curing frame framework is formed; a transverse plate is arranged on each layer of transverse support, threaded holes are formed in the transverse plates and used for mounting cushion blocks, and the distance between the threaded holes is designed according to the size of a concrete sample; from top to bottom, a reserved area is arranged between the adjacent transverse plates; the cushion block comprises a rubber pad and a T-shaped cylinder, the rubber pad is fixed on the upper surface of the T-shaped cylinder, and the rubber pad is used for reducing the acting force of the T-shaped cylinder on the concrete test piece and playing a role in buffering; the bottom of the T-shaped cylinder is provided with threads for mounting the cushion block on the threaded hole of the transverse plate; four cushion blocks which are adjacent in the transverse direction and the longitudinal direction are in a group and are connected into a square for placing a concrete sample.

In the utility model, the transverse plate is a complete plate, and holes causing water leakage of the transverse plate are not required to be formed except for the threaded holes.

In the utility model, the transverse plate is made of a material which is not easy to corrode.

In the utility model, the threaded hole on the transverse plate is matched with the thread of the T-shaped cylinder.

In the utility model, the diameter of the upper part of the T-shaped cylinder is proper, and stress concentration is caused by over-small diameter, so that a concrete test piece is damaged.

According to the utility model, after the cushion block is installed, the top surface of the cushion block is proper in height from the transverse plate, and water drops or running water washing is easy to occur when the height is too low.

The utility model has the beneficial effects that: in the utility model, the transverse plate is a complete plate, and accumulated water cannot drop onto a lower-layer concrete test piece; the cushion block heightens the concrete test piece, so that the bottom surface of the concrete test piece is better maintained in a standard way and is not washed by running water.

Detailed Description

The present invention is further described with reference to the following embodiments and the accompanying drawings, but it should be noted that the following embodiments are preferred examples of the present invention, and do not limit the present invention in any way, and any simple modification and change made to the following embodiments according to the technical scheme of the present invention belong to the protection scope of the technical scheme of the present application.

Example 1: as shown in fig. 1-2, a concrete specimen curing rack is composed of a bracket 1 and a transverse plate 3, wherein the bracket comprises a plurality of vertical brackets and a plurality of transverse brackets to form a stable curing rack framework; a transverse plate 3 is arranged on each layer of transverse support, the transverse plates 3 can be made of steel and are provided with threaded holes for mounting the cushion blocks 2, and the distance between the threaded holes is designed according to the size of the concrete sample, so that the concrete sample can be conveniently and practically placed after the cushion blocks 2 are mounted; the maintenance frame is provided with a reserved area with a certain height, and the situation that the placing height of the concrete sample 5 on the lowest layer is too low is avoided.

Referring to fig. 1-3, a cushion block for curing a concrete sample comprises a rubber pad 6 and a T-shaped cylinder 7. The rubber pad 6 is fixed on the upper surface of the T-shaped cylinder 7, and the rubber pad 6 is used for reducing the acting force of the T-shaped cylinder 7 on the concrete test piece 5 and playing a role in buffering; the lower end of the T-shaped cylinder 7 is provided with threads for mounting the cushion block 2 on the curing frame; the four adjacent cushion blocks 2 form a group and are connected into a square, and a concrete test piece 5 can be placed in the square; a maintenance frame is equipped with the cushion of a large amount, can satisfy placing and the maintenance of concrete sample.
