Description

A recyclable multifunctional horse stool

technical field

The utility model relates to a horse stool in building construction, in particular to a recyclable multifunctional horse stool.

Background technique

In the construction of cast-in-place concrete slabs, it is inevitable to walk on the slabs where the steel bars have been bound. Especially when pouring floor concrete, due to the casual stepping of workers, the steel bars on the upper floor of the floor are bent, which not only increases the protective layer of the upper steel bars on the floor, but also reduces the effective height of the upper steel bars and the load-carrying capacity of the floor. Especially for cantilevered slabs such as awnings and balconies, if the upper steel bars are severely stepped on and the protective layer of the steel bars is too large, it may cause the cantilevered slabs to overturn.

In order to ensure that the effective height of the upper steel bars does not decrease and the protective layer of the steel bars does not increase, the upper steel bars on the floor are generally placed on cushions, plastic or steel bar stools, and the upper floor steel bars are supported by the spacers or horse stools. Blocks and plastic horse stools have poor bearing capacity and are easy to be crushed or overturned, and the actual effect is not good. Ordinary steel bar stools need to consume a lot of steel bars, and because they cannot be turned around, the cost is high; moreover, the steel bar bar stools are placed under the upper layer of steel bars on the floor, and construction personnel will definitely step on the upper layer of steel bars during work, which cannot ensure that the upper layer of steel bars will not be disturbed, and the effect will be poor. Not ideal.

In terms of controlling the thickness and flatness of concrete slabs, the traditional method is to control the thickness and flatness of the slab by using the control elevation on the shear wall and the main reinforcement of the column. Since there are control points around the slab and no control point at the center of the slab, it is difficult to precisely control the thickness and flatness of the floor slab poured in this way. Some construction companies use cuttings to control the thickness of the slab. If the contact surface touched by the cuttings is not the bottom form of the slab but the steel bar pad, it will affect the control of the thickness of the slab. Moreover, this method is time-consuming and laborious, and the effect is not obvious.

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the utility model is not limited to the following embodiments.

As shown in Figures 1-2, a recyclable multifunctional horse stool includes bench legs 4, short stool legs 1, top frame 2, cross ribs 3, L-shaped fixed shaft 6, and hooks. The cross rib 3 is fixed on the inside of the top frame 2, the short stool legs 1 are fixed on two opposite corners of the top frame 2, and the bench legs 4 are fixed on the other two pairs of the top frame 2. At the corner, the L-shaped fixed shaft 6 is fixed on the top of the bench leg 4, and the hook is sleeved on the L-shaped fixed shaft 6.

The top of the bench leg 4 is provided with a green ring elevation line 8, a yellow ring elevation line 9, and a red ring elevation line 10, the green ring elevation line is 5mm higher than the top frame 2, and the yellow ring elevation line 9 is higher than the green ring elevation line. Line 8 is 5mm higher, and red ring elevation line 10 is 5mm higher than yellow ring elevation line 9.

The hook includes an L-shaped hook 7 and a sleeve 5 , and the sleeve 5 is fixed at the end of the L-shaped hook 7 . The sleeve 5 is sleeved on the L-shaped fixed shaft 6 . The casing 5 and the L-shaped fixed shaft 6 are parallel to the horizontal frame, and the L-shaped hook 7 is perpendicular to the horizontal frame. During use, the L-shaped hook 7 is used to support and hang the reinforcement distribution bar 11 of the upper floor on the floor. The size of the plate thickness can be marked on the casing 5 as a construction mark.

The height of the bench legs 4 at the bottom of the top frame 2 is the same as the height of the short stool legs 1 .

The bench legs 4, the short stool legs 1, the top frame 2, and the cross ribs 3 can all be made of steel bars with a diameter of 14mm or 16mm. Sleeve 5 can adopt the steel pipe that diameter is 20mm to make. The L-shaped hook 7 can be made with a steel bar with a diameter greater than 10mm.

The elevation of the upper surface of the top frame 2 is the same as the elevation of the top surface of the floor slab. The top frame 2 and the cross rib 3 are on the same plane.

The using method of the present utility model is as follows:

1) After the bottom layer of the slab has been bound and the pipelines are laid, arrange the horse stool quincunx pattern in the grid of the steel mesh sheet, and put the upper layer of steel bar distribution bar 11 into the horse stool L-shaped hook 7. Because the height of the L-shaped hook 7 from the upper surface of the horse stool cross reinforcement 3 is just equal to the thickness of the protective layer+the diameter of the negative moment reinforcement+the diameter of the distribution reinforcement; so the precise control of the upper reinforcement protection layer on the floor can be realized.

Since the height of the horse stool is equal to the thickness of the board and higher than the negative moment tendons, the operator can effectively avoid the negative moment tendons from being stepped on when walking on the horse stool. It overcomes the problems that the negative bending moment tendon is severely deformed by trampling on it in the past, resulting in an excessively large protective layer of the steel bar and a decrease in the bearing capacity of the floor slab.

2) Mark the thickness of the board on the outer wall of the casing of the horse stool. The reinforcement worker places the horse stool on the floor corresponding to the thickness of the floor. Since the elevation of the upper surface of the cross reinforcement 3 of the horse stool is equal to the thickness of the floor, the horse stool is placed completely. Finally, the upper surfaces of all horse stool cross ribs 3 should be at the same level. If individual horse stools are lower or higher than the surrounding horse stools, it means that there is a problem with the elevation of the board where the horse stool is located. This kind of review method can effectively correct the thickness deviation of the floor slab caused by the mistakes of the setting-out personnel or formwork personnel.

3) Use the plane where the horse stool cross reinforcement 3 is located as the floor leveling base point, place the scraping ruler on the two horse stools beside the floor, use the first horse stool as the fulcrum, and rotate the scraping ruler from the second horse stool to the The third horse stool; then use the third horse stool as a fulcrum, rotate the scraper from the first horse stool to the fourth horse stool, and so on, you can use the scraper to scrape out the large plane of the entire floor. After the floor concrete is leveled, if the concrete does not cover the upper surface of the horse stool cross reinforcement 3, it means that the floor thickness is too thin and needs to be adjusted; if the concrete covers the horse stool cross reinforcement 3 and the upper surface does not exceed the green ring elevation line 8, it means that the floor The thickness control is very good and no adjustment is required; if the concrete reaches the red ring elevation line 10, it means that the thickness of the floor slab deviates and needs to be adjusted. Therefore, the thickness of the floor slab is accurately controlled by using the color ring elevation line on the upper surface of the horse stool cross reinforcement 3 and the bench legs 4 . In the same way, the horse stool can also be used to precisely control the flatness of the floor.

4) After the concrete pouring, vibrating and leveling of the floor slab are completed, the reinforcement distribution bars 11 on the upper floor can be propped up by the poured concrete. At this time, the L-shaped hook 7 is pulled, so that the hook rotates around the L-shaped fixed shaft 6 through the sleeve pipe 5, so that the hook is separated from the steel bar. The horse stools were then removed from the concrete floor, allowing the horse stools to be recycled. The construction personnel can recycle the horse stool while carrying out the second plastering of the floor concrete and the film covering maintenance of the floor.
