Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and more specifically, particularly relates to a BIM-based assembled building component. Background Art
[0002] BIM technology can intuitively display the spatial layout of a building and the relationship between its various parts. For example, when installing stairs, AR visual technology can be used to pre-position the installation position of the stairs, helping workers quickly find the installation position and improve work efficiency.
[0003] However, during the specific construction process, there are still two deficiencies when workers install stair components:
[0004] First, when installing the stair components, fixing nails are needed to fix the front and rear ends of the stairs. However, the weight of the stairs is large, which makes the fixing nails easily move, resulting in poor stability of the stairs.
[0005] Secondly, the surface of each step of the stairs is smooth, and people are prone to slipping when walking on the stairs. In addition, the right angles at the outer ends of the stairs are directly stepped on by people's feet and are subject to the greatest force, so the outer right angles of the stairs are prone to wear. Utility Model Content
[0006] In order to solve the above technical problems, the utility model provides a BIM-based assembled building component to solve the problem that during the installation of existing stair components, the fixing nails are easily displaced due to the heavy weight of the stairs, resulting in poor stability of the stairs, and the surface of each step of the stairs is smooth, which makes people easily slip when walking on the stairs.
[0007] The purpose and effect of the BIM-based assembled building component of the utility model are achieved by the following specific technical means: a BIM-based assembled building component, including a staircase main body;
[0008] The upper surface of the staircase body is provided with three fixing holes on the front and rear sides respectively, the left and right end surfaces of the staircase body are symmetrically provided with two sets of first grooves, and the upper surface of the staircase body is provided with a set of plug holes on the left and right sides respectively;
[0009] A clamping column, wherein the upper end of the clamping column is divided into a cylindrical structure, and the lower end of the clamping column is divided into a conical structure. The clamping column is clamped in a fixing hole on the surface of the stair body, and a cross groove is opened on the upper end surface of the clamping column;
[0010] The handrail rod has an inclined structure as its main body, and the lower end surface of the handrail rod is evenly equipped with connecting rods, which are cylindrical structures, and the lower end portion of the connecting rod is clamped in a socket on the surface of the stair main body.
[0011] Furthermore, resistance bars are evenly installed on the surface of each step of the staircase body, and the outer ends of the resistance bars are arc-shaped structures.
[0012] Furthermore, an iron column is installed at the right-angled part of the outer end of each step of the stair body, and the inner end part of the iron column is embedded in the stair body. Two second grooves are respectively provided on the front and rear sides of the upper end face of the stair body, and the second grooves are interconnected with the first grooves.
[0013] Furthermore, three vertical grooves are provided at the upper position of the inner end surface of the fixing hole, and the inner end surface of the fixing hole is also provided with a transverse track groove of an annular structure, and the transverse track groove is communicated with the vertical groove.
[0014] Furthermore, three limit blocks are fixedly installed above the outer end surface of the clamping column, the height of the limit blocks is the same as the height of the horizontal track groove, and the structure of the limit blocks is the same as that of the vertical groove.
[0015] Furthermore, the inner end surface of the insertion hole is provided with three pouring grooves in a ring shape, and the outer end surface of the connecting rod is provided with a groove in a ring shape below.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] In the utility model, resistance bars are evenly installed on the upper end surface of each step of the stair main body, and the outer end surface of the resistance bar is an arc-shaped structure, so that when people walk on the surface of the stair main body, the resistance bar can increase the friction between the soles of people's feet and the stair main body to avoid slipping. The outer right-angle part of each step of the stair main body is embedded with an iron column. When people walk on the surface of the stair main body for a long time, the iron column can reduce wear and tear, thereby avoiding wear and tear on the outer end of the stair main body.
[0018] In addition, three fixing holes are respectively provided at the front and rear ends of the upper end surface of the stair main body. When people install the stair main body, they can clamp the clamping column into the fixing hole, which is convenient for people to install the stair main body. Three vertical grooves are provided above the inner end surface of the fixing hole, and three limit blocks are fixedly installed above the outer end surface of the clamping column. Workers can clamp the limit blocks at the outer ends of the clamping column into the vertical grooves. By setting the vertical grooves and the transverse track grooves to be interconnected, the limit blocks can enter the transverse track grooves from the vertical grooves. After that, the workers can rotate the clamping column with the help of tools. At this time, the limit blocks are located inside the transverse track grooves. The limit blocks can play a limiting role, thereby improving the stability of the clamping column inside the fixing hole.
[0019] In addition, two first grooves are respectively provided at the left and right ends of the stair main body, and the first groove and the second groove are interconnected. When workers are lifting and installing the stair main body, they can pass the rope through the first groove and the second groove, so as to facilitate the workers' lifting work on the stair main body. A group of sockets are respectively provided at the left and right ends of the upper end surface of the stair main body, and workers can clamp the connecting rod at the lower end of the handrail rod into the socket. Since the inner end surface of the socket is annular and has three pouring grooves, after the workers clamp the connecting rod into the inside of the socket, they can pour mud into the pouring groove, so that the lower end of the connecting rod can be fixed in the socket.
