Description

Technical Field

[0001] The present application relates to the technical field of concrete testing, and in particular to a concrete standard curing test block placement rack. Background Art

[0002] In the construction industry, concrete test blocks are a means of evaluating the strength of concrete. After the concrete test blocks are made with special molds, they need to be cured for a fixed time. After the concrete blocks are completely solidified, subsequent tests can be carried out. There are two ways to cure concrete test blocks. One is standard curing, which is to place the concrete test blocks in a curing room and cure them by controlling the temperature and humidity within the standard range. The other is co-curing, which is to place the concrete test blocks in the same environment as the building and cure them under the same conditions as the building. Since standard curing needs to be carried out in a relatively closed curing room, in order to improve space utilization, concrete test blocks are usually placed on a shelf and the surface of the test blocks is kept moist by regular spraying. For example, Chinese patent application number 202222025812.4 discloses a standard curing rack for concrete test blocks, including a base, a universal wheel arranged on the lower surface of the base, a tray placed on the upper surface of the base, four vertical frames fixed on the upper surface of the base, a plurality of support plates arranged in the middle of the four vertical frames, and a frame sleeve arranged on the vertical frame. There is no limiting structure on this type of standard curing rack. If the concrete test blocks are placed too closely, the sides of the concrete test blocks may not be fully moistened during spraying, affecting the quality of curing. In addition, the height of the commonly used racks is fixed, and users cannot increase or decrease it by themselves. Moreover, the racks can only be transported as a whole, which causes inconvenience in operation and affects user use. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a concrete standard curing test block placement rack, which facilitates the placement of concrete test blocks by setting a limit device on the shelf. The overall structure adopts an assembled structure, and users can increase or decrease the number of layers by themselves. It can be disassembled and transported during transportation, which is convenient for user operation.

[0004] This application is implemented through the following technical solutions:

[0005] The present application proposes a concrete standard curing test block placement rack, comprising: a top rack and a middle rack, wherein the top rack and the middle rack are both provided with lower connecting columns at the bottom, and the middle rack is provided with upper connecting columns at the top, and the top rack and the middle rack are connected to each other through upper connecting columns and lower connecting columns; the top rack and the middle rack are both provided with a plurality of angle steels and T-shaped steels, which are arranged in parallel, and a plurality of placement grooves are formed on the top rack and the middle rack through the angle steels and T-shaped steels, and limit blocks are arranged at intervals in the placement grooves.

[0006] Furthermore, the lower connecting column and the upper connecting column are both square tubes, wherein the lower connecting column can be inserted into the upper connecting column, and the size of the inner wall of the upper connecting column is equal to the size of the outer wall of the lower connecting column.

[0007] Furthermore, the lower connecting column and the upper connecting column are both provided with through holes, and after the lower connecting column is inserted into the upper connecting column, the through holes on the lower connecting column and the upper connecting column are aligned with each other, and the lower connecting column and the upper connecting column are connected by a pin or a nut.

[0019] like Figures 1 to 3 As shown, an embodiment of the utility model provides a concrete standard curing test block placement rack, including: a top rack 1 and a middle rack 2, the top rack 1 and the middle rack 2 are both provided with lower connecting columns 3 at the bottom, the middle rack 2 is provided with upper connecting columns 4 at the top, the top rack 1 and the middle rack 2 and the middle racks 2 are connected to each other through the upper connecting columns 4 and the lower connecting columns 3; the top rack 1 and the middle rack 2 are both provided with a plurality of angle steels 5 and T-shaped steels 6, the angle steels 5 and the T-shaped steels 6 are arranged in parallel, and a plurality of placement grooves 7 are formed on the top rack 1 and the middle rack 2 by the angle steels 5 and the T-shaped steels 6, and limiting blocks 8 are arranged in between the placement grooves 7.

[0020] The lower connecting column 3 of the lowest middle rack 2 can be used as a support foot to keep the middle rack 2 at a certain distance from the ground. There is no upper connecting column 4 on the top of the top rack 1, which is convenient for placing concrete test blocks on the top rack 1. The top rack 1 and the middle rack 2 are connected to each other through the upper connecting column 4 and the lower connecting column 3. The user can increase the number of middle racks 2 as needed to meet the maintenance needs of different numbers of concrete test blocks, and the entire placement rack can be disassembled into a single top rack 1 and middle rack 2 to reduce the space occupied during transportation and facilitate transportation.

[0021] When placing the concrete test blocks, they are placed from the inside to the outside, and the concrete test blocks are placed in the placement groove 7 in sequence. The placement groove 7 is provided with a limit block 8. The limit block 8 is stuck between two concrete test blocks to prevent the concrete test blocks from being too close. During maintenance, the test blocks on the placement rack are sprayed by a sprayer. The concrete test blocks are separated by a distance by the limit block 8 and the T-shaped steel 6. The atomized small droplets can enter between the concrete test blocks, so that the sides of the concrete test blocks can be fully wetted.

[0022] In a preferred embodiment, the lower connecting column 3 and the upper connecting column 4 are both square tubes, wherein the lower connecting column 3 can be inserted into the upper connecting column 4, and the size of the inner wall of the upper connecting column 4 is equal to the size of the outer wall of the lower connecting column 3, so that after the lower connecting column 3 is inserted into the upper connecting column 4, the shaking can be reduced to ensure the stability of the entire placement rack.

[0023] In a specific embodiment, Figure 2 , Figure 3 As shown, the lower connecting column 3 and the upper connecting column 4 are both provided with through holes, and after the lower connecting column 3 is inserted into the upper connecting column 4, the through holes on the lower connecting column 3 and the upper connecting column 4 are aligned with each other, and the lower connecting column 3 and the upper connecting column 4 are connected by a latch or a nut, and the lower connecting column 3 and the upper connecting column 4 are locked by the latch or the nut to ensure the stability of the placement rack. When the placement rack needs to be disassembled, after loosening the latch or the nut, the top rack 1 or the middle rack 2 is pulled up to separate the lower connecting column 3 from the upper connecting column 4, and the disassembly operation is completed.

[0024] In a specific embodiment, the spacing distance of the limit blocks 8 is 120mm to 150mm, the diameter of the limit blocks 8 is 15mm to 25mm, and the height is 10mm to 20mm. The concrete test blocks are separated by the limit blocks 8 to avoid the concrete test blocks being too close to each other and affecting the curing effect. The height of the upper connecting column 4 is 200mm to 250mm, so that each layer on the placement rack is spaced a distance apart, which is convenient for storing and taking out the concrete test blocks.

[0025] Specifically, the middle part of the angle steel 5 and the middle part of the T-shaped steel 6 are connected to each other through a cross bar 9 to improve the bending resistance of the middle part of the angle steel 5 and the T-shaped steel 6, so as to support the concrete test block. Each top-level frame 1 or middle-level frame 2 is provided with 2 to 4 placement grooves 7, which can place multiple concrete test blocks to improve space utilization.

[0026] Specifically, there is one top shelf 1 and at least one middle shelf 2. The number of layers of the middle shelf 2 can be increased or decreased according to demand to meet the needs of different users.

[0027] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
