Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of house construction, in particular to a reusable floor slab steel bar horse stool. Background Art
[0002] In the social environment where the country vigorously advocates energy conservation, environment protection and sustainable development, the development and application of green construction technology is becoming more and more important. The horse stool bar is an indispensable measure steel bar. It plays a supporting and fixing role for the upper steel bars in the construction of reinforced concrete slabs with double reinforcement or negative bending moment bars at the support, and at the same time needs to bear various construction live loads. At present, the common practice in the construction process of traditional reinforced concrete floor slabs in China is to use steel bars to process horse stool bars. These horse stool bars are made of steel bars with the same specifications or one lower specification as the slab bars. After the concrete is poured, the horse stool bars will be completely hidden in the concrete and cannot be reused. This part of the steel bars is a considerable waste in terms of construction costs and steel resources. In this context, it is particularly important to design a detachable, repeatedly circulated, material-saving and environmentally friendly floor slab steel bar horse stool that has a lower amortization cost and is easy to operate and use.

[0004] The utility model provides a reusable floor steel bar horse stool, comprising a vertical screw, an adjusting handle and two internal threaded sleeves, the two internal threaded sleeves are both located in the vertical direction and are coaxially arranged, the two internal threaded sleeves are fixedly connected by two support rods with scales, the vertical screw is threadedly matched with the two internal threaded sleeves, the adjusting handle is located in the horizontal direction and is welded to the top of the vertical screw, two horizontally arranged clamping rods are welded to the bottom of the vertical screw, the two clamping rods are spaced apart up and down, three downwardly inclined support legs are welded to the lower internal threaded sleeve, the three support legs are evenly distributed along the circumference of the internal threaded sleeve, and the three support legs are combined into a tripod support frame; the vertical screw is provided with a marking line, and when the clamping rod contacts the ground, the marking line on the vertical screw is flush with the zero scale line on the support rod.
[0005] The two internal thread sleeves and the two support rods are welded and connected as a whole. The tripod support frame connected thereto can stably support the floor slab. The vertical screw rod is rotated by adjusting the handle to adjust the height of the clamp rod on it to meet the construction needs of different floors. The working principle of the floor slab steel bar horse stool of the present invention is as follows: the entire floor slab steel bar horse stool takes the floor slab template of the layer as the focus point, and the height of the clamp rod on the vertical screw rod is adjusted by adjusting the handle, so that the upper steel bar is clamped between the two clamp rods, and a certain pulling force is given to the upper steel bar to separate the upper steel bar from the lower steel bar; secondly, the tripod support frame is distributed in an equilateral triangle, and the clamp rod projection is located at the center of the triangle to ensure the stability of the floor slab steel bar horse stool. By rotating the adjustment handle, the support height of the clamp rod can be adjusted to adapt to floors of different thicknesses. When in use, each horse stool is installed independently. Before the initial setting after the concrete is poured, the rotating handle is loosened to separate the clamp rod from the upper steel bar, and the horse stool is lifted upward. The dismantled horse stool only needs to be cleaned up and can be immediately put into the next floor for construction. The operation is very convenient, can be reused, and saves costs. Specifically, the adjustment handle, three supporting legs and two clamping rods are all made of φ14HRB400E steel bars; the vertical screw rod is made of φ16HRB400E steel bars; the supporting rod is made of φ14HPB300 steel bars; and the internal thread sleeve is made of φ16 straight thread sleeve.
[0006] Preferably, the scale lines on the support rod are arranged from bottom to top, and the zero scale line is aligned with the top end of the lower internal threaded sleeve. This arrangement is reasonable, and the operator can intuitively record the adjusted height of the card plate from the interval between the two internal threaded sleeves.
[0007] Preferably, the three supporting legs are respectively hinged to the lower internal threaded sleeve, and when each supporting leg is opened outward to a maximum angle, the three supporting legs can form a tripod support frame, which is to facilitate subsequent transfer and transportation.
[0008] Preferably, the precision of the scale lines on the support rod is 1 cm. This setting is very reasonable and meets the needs of daily construction.
[0009] Compared with the prior art, the technical solution provided by the utility model has the following technical effects: it is simple and fast to assemble, convenient to hoist, suitable for housing construction sites, environmentally friendly, high in construction efficiency and stability, and ensures construction quality and safety. The floor steel bar horse stool described in the utility model can be reused, and the height can be adjusted to be suitable for floors of different thicknesses; it contributes to reducing construction costs and saving steel bar resources. Finally, the horse stool can also be depreciated, has good promotion and practical value, and will produce good economic benefits after widespread promotion and application.
