Description

Technical Field

[0001] This utility model relates to the field of UHPC prefabricated staircase technology, specifically a UHPC prefabricated staircase that is easy to align and assemble. Background Technology

[0002] UHPC is an abbreviation for Ultra High Performance Concrete, also known as Reactive Powder Concrete. It is the most innovative cement-based engineering material in the past thirty years, achieving a great leap forward in the performance of engineering materials.

[0003] The design theory of ultra-high performance concrete is the maximum bulk density theory. Its constituent materials consist of particles of different sizes that form the densest packing in an optimal proportion. That is, the gaps between millimeter-sized particles (aggregates) are filled by micron-sized particles (cement, fly ash, mineral powder), and the gaps between micron-sized particles are filled by submicron-sized particles (silica fume).

[0004] This material is widely used in building construction. In multi-story buildings, the common building structure is the floor structure that connects the floors. To improve construction efficiency, many places use a prefabricated building structure. Prefabricated staircases can give full play to the advantages of factory manufacturing, solve the problems of difficult on-site staircase formwork and difficulty in controlling the quality of concrete pouring. The finished product has good appearance quality, and the on-site installation speed of the staircase is fast, which greatly reduces the construction time of the standard floor by about half a day, reduces the on-site labor intensity, improves production efficiency, and improves the quality of the project and the building.

[0005] For example, utility model application CN201921534268.8 discloses an electric clamp-type cold-cutting flying saw. This electric clamp-type cold-cutting flying saw uses a drive gear, a driven gear, a first motor, a first flying saw gear, and a second flying saw gear to achieve flexible up-and-down movement of the flying saw gear. At the same time, the interval between the first and second flying saw gears is used to achieve quantitative flying sawing, which improves the mass production and flexibility of the electric clamp-type cold-cutting flying saw. However, similar cold-cutting flying saws in the above-mentioned documents do not have a corresponding structure to assist the saw in stable displacement while working. When the equipment is in operation, it does not have an automatic feeding structure, which is lacking in overall efficiency and practicality.

[0006] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a UHPC prefabricated staircase that is easy to align and assemble. Utility Model Content

[0007] The purpose of this invention is to provide a UHPC prefabricated staircase that is easy to align and assemble, so as to solve the problems mentioned in the background art.

[0008] To achieve the above object, the present utility model provides the following technical solutions: A UHPC prefabricated staircase convenient for alignment and assembly, comprising a step component and an upper docking component. The top surface and the bottom surface of the step component are respectively cast with a first strengthening layer and a second strengthening layer. A plastic cushion layer covers one side surface of the first strengthening layer away from the step component. A support beam bone is horizontally arranged inside the step component. The upper docking component is connected to the upper left end of the step component, and a lower docking component is connected and arranged at the bottom right of the step component. A lighting component is vertically arranged on the middle side surface of the step component. The upper docking component includes a first docking beam mortise, a first support column, and a first fixing steel pin. A first support column is horizontally cast at the bottom of the first docking beam mortise, and a first fixing steel pin is installed through the center of the first support column.

[0009] Further, the step component includes a flight beam frame, a first docking tenon pile, and a second docking beam mortise. A first docking tenon pile is integrally cast at the upper left end of the flight beam frame, and a second docking beam mortise is integrally cast at the bottom right of the flight beam frame.

[0010] Further, the first strengthening layer and the second strengthening layer have the same structural material, and both the first strengthening layer and the second strengthening layer cover the upper and lower surfaces of the step component.

[0011] Further, the support beam bone is a hollow hexagonal tubular structure, and the support beam bones are horizontally cast inside the step component at equal distances.

[0012] Further, the lower docking component includes a second docking tenon pile, a second support column, and a second fixing steel pin. A second support column is vertically cast on the left side of the second docking tenon pile, and a second fixing steel pin is installed through the bottom of the second support column.

[0013] Further, the inner surface structure of the first docking beam mortise matches the outer surface structure of the first docking tenon pile, and the outer surface structure of the second docking tenon pile matches the inner surface structure of the second docking beam mortise.

[0014] Further, the lighting component includes a fixing frame, a protective frame, a solar light strip, and a waterproof cover. A protective frame is installed on one side of the fixing frame away from the step component, and a solar light strip is arranged and installed inside the protective frame.

Detailed Implementation

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

The upper docking component 6 is connected to the upper left end of the step component 1, and a lower docking component 7 is connected and arranged at the bottom right of the step component 1. A lighting component 8 is vertically arranged on the middle side surface of the step component 1. The step component 1 includes a flight beam frame 101, a first docking tenon pile 102, and a second docking beam mortise 103. The first docking tenon pile 102 is integrally cast at the upper left end of the flight beam frame 101, and the second docking beam mortise 103 is integrally cast at the bottom right of the flight beam frame 101. The first strengthening layer 2 and the second strengthening layer have the same structural material, and both the first strengthening layer 2 and the second strengthening layer 3 cover the upper and lower surfaces of the step component 1. The lighting component 8 includes a fixing frame 801, a protective frame 802, a solar light strip 803, and a waterproof cover 804. A protective frame 802 is installed on the side of the fixing frame 801 away from the step component 1, and a solar light strip 803 is installed inside the protective frame 802. The solar light strip 803 is covered with a waterproof cover 804 on the outside. The protective frame 802 is arranged in a "C" - shaped structure, and the waterproof cover 804 covers the outside of the solar light strip 803 in a hemispherical structure. By means of the plastic cushion layer 4 covered on the top surface of the step component 1, it can effectively prevent the entire step component 1, including the first strengthening layer from slipping during the process of stepping, reducing the problem of falling and getting injured from the stairs. At the same time, it can also protect the step component 1 and the first strengthening layer 2 from external erosion to a certain extent. The lighting component 8 installed on the side vertical edge of the step of the step component 1, in which the solar light strip 803 can effectively utilize the external natural light for power generation and provide a certain degree of lighting at night.

[0027] The support beam bone 5 is a hollow hexagonal tubular structure, and the support beam bones 5 are horizontally cast at equal distances inside the step component 1. Since several support beam bones 5 are arranged inside the flight beam frame 101, with the setting of its hexagonal hollow structure, it can effectively improve the material cost of the entire step component 1. Not only can the weight of the components of the entire step component 1 be reduced to a certain extent, achieving structural lightweight, but also because of the reduction of the materials used, its manufacturing cost can be saved to a certain extent. Under the same volume of raw materials, more step components 1 can be produced in batches, and the sales profit of the product can be further increased.

[0028] The upper connecting component 6 includes a first connecting beam mortise 601, a first support column 602, and a first fixing steel rod 603. The first support column 602 is horizontally cast at the bottom of the first connecting beam mortise 601, and the first fixing steel rod 603 is installed through the center of the first support column 602. The lower connecting component 7 includes a second connecting tenon 701, a second support column 702, and a second fixing steel rod 703. The second support column 702 is vertically cast on the left side of the second connecting tenon 701, and the second fixing steel rod 703 is installed through the bottom of the second support column 702. The inner surface structure of the first connecting beam mortise 601 matches the outer surface structure of the first connecting tenon 102, and the outer surface structure of the second connecting tenon 701 matches the inner surface structure of the second connecting beam mortise 103. This is achieved through the stepped component 1. The upper and lower connecting components 6 and 7, which are pre-cast on the upper and lower sides of the docking position, utilize the matching structure of the first connecting beam mortise 601 and the first connecting tenon 102, and the matching structure of the second connecting beam mortise 103 and the second connecting tenon 701, so that the entire step assembly 1 can be directly slid into the first connecting beam mortise 601 and the second connecting tenon 701 on the upper and lower sides of the step beam frame 101 in the horizontal direction through the first connecting tenon 102 and the second connecting beam mortise 103 set on the upper and lower sides of the step beam frame 101, respectively. By using an installation structure similar to mortise and tenon, it is possible to achieve rapid alignment and assembly while ensuring the stability of its structural connection. With the through fixation of the first fixing steel rod 603 and the second fixing steel rod 703, the firmness of the structural connection can be further improved.

[0029] In summary, as Figures 1 to 4 As shown, this UHPC prefabricated staircase, which is easy to align and assemble, is used by first casting and setting the first connecting beam 601 and the first support column 602 in the upper connecting component 6, and the second connecting tenon 701 and the second support column 702 in the lower connecting component 7, respectively, on the upper and lower sides of the position where the step component 1 needs to be connected and assembled. After curing, the entire step component 1 is lifted vertically by external hoisting equipment, and the first connecting tenon 102 is oriented toward the first connecting beam 601 and the second connecting beam 103 is oriented toward the second connecting tenon 701, and they are slid and inserted horizontally in the horizontal direction until they are connected in place. Then, the first fixing steel rod 603 and the second fixing steel rod 703 are passed through the first support column 602 and the second support column 702 respectively to fix both sides of the entire stair beam frame 101 through, so as to improve the structural stability and firmness of the entire step component 1 connecting the upper connecting component 6 and the lower connecting component 7.

[0030] The supporting beams 5 inside the stair beam frame 101 effectively reduce the structural weight of the entire stair assembly 1 and improve the ease of hoisting the entire stair assembly 1. At the same time, the plastic pad 4 covering the surface of the first reinforcing layer 2 can prevent slipping and falling when walking on the surface of the stair assembly 1. By using the fixing frame 801 and the protective frame 802, the solar light strip 803 is installed on the side surface of the stair beam frame 101, which can effectively utilize external natural light to generate electricity, thereby providing effective lighting at night and making it easier for people to walk up the stairs at night, thus improving safety.
