Description

Technical Field

[0001] The present invention relates to the field of building construction, and particularly to a pre-assembled structure for building construction. Background Art

[0002] Building construction refers to the process of transforming various building materials, components, and equipment into buildings or structures through a series of construction techniques and organizational management means in accordance with the requirements of design drawings and relevant specifications; the pre-assembled structure is prefabricated and manufactured outside the building site, and a large number of operations that originally needed to be carried out on the construction site, such as cutting, welding, and assembling of components, are transferred to the factory to complete, which can effectively reduce the on-site construction time. Especially for some complex building structures, it can significantly shorten the overall construction period; in the traditional portal frame structure, the top beam and the steel beam are usually pre-assembled and connected to form the basic framework of the ceiling, and then the plates are laid on the top beam.

[0003] Since part of the ceiling is triangular in shape and has a bevel structure, and when the top beam and the steel beam are spliced, the installation of the top beam is usually carried out at a high altitude. During the splicing operation, workers need to operate at a high altitude, and the staff needs to frequently move the working position to complete the splicing and fixing of the top beam in different areas. Especially when moving to the eaves of the ceiling, the operators need to operate on an inclined and narrow working surface, and it is extremely easy to cause high-altitude falling accidents due to unstable center of gravity and difficult effective fixation of protective facilities; according to relevant statistical data, in building construction high-altitude operation accidents, accidents caused by working surface movement and edge operation account for more than 35%. At the same time, frequent position movement not only increases the physical consumption of the operators, but also reduces the construction efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a pre-assembled structure for building construction, which solves the problem of high incidence of accidents caused by working surface movement and edge operation.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A pre-assembled structure for building construction includes a slide rail group installed on the steel beam and connectors installed at both ends of the top beam. A roller is installed at one end of each connector away from the top beam, and several groups of rollers roll down from high to low along the slide rail group, and the fixing part of the connector moves linearly along the slide rail group.

[0006] The slide rail group includes two single slide rails. A number of positioning holes are provided in the single slide rail, and the positioning holes are arranged at intervals along an inclined track. Positioning columns are slidably installed at the fixing parts of several connectors. When each positioning column moves with the connector, it will align with the corresponding positioning hole on the preset track. The positioning column can cross the non-target positioning holes, and the positioning column is snapped into the target positioning hole through an elastic piece.

[0007] Preferably, the fixing part of the connecting piece includes a fixed block and a sliding piece which are fixed to each other. The roller is rotatably connected to the fixed block through an inner shaft. The sliding piece is slidably connected to the single slide rail. There is a gap between the fixed block and the single slide rail. The rotating part of the connecting piece includes a rotating shaft and a fixing piece. One end of the rotating shaft is fixed to the fixing piece, and the other end is rotatably connected to the fixed block. The fixing piece is used to be fixed on the top beam.

[0008] Preferably, a through hole is formed inside the top beam. A rope is fixedly connected inside the through hole of the top beam at the lowest position. The rope is slidably connected to the through holes of the other top beams.

[0009] Preferably, the height of the through hole is greater than the height of the rotating shaft adjacent thereto.

[0010] Preferably, a lubricating oil is applied to the contact surface between the sliding piece and the single slide rail.

[0011] Preferably, a notch is formed inside the fixed block. The positioning post slides in the notch. The fixed end of the elastic piece is fixed to the notch, and its movable end is fixedly connected to the positioning post.

[0012] Preferably, a plurality of grooves are provided inside the single slide rail. Each groove corresponds to the positioning hole adjacent thereto.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Through the cooperation of the slide rail group and the roller, the top beam is slidably installed along the slide rail. The operator only needs to operate in the fixed area at the top of the ceiling, reducing the need for movement, and solving the problem of high accident rate caused by the movement of the operation surface and edge operation in the background technology. Through the cooperation between the positioning post and the obliquely arranged positioning holes, the rapid positioning and fixing of the top beam are realized, avoiding the repeated adjustment of the traditional manual alignment and reducing the labor consumption; By arranging the ropes to tighten and fix the top beam, a tensile force can be applied to each top beam, making the plurality of top beams more stable during the installation process, reducing the shaking and displacement between the top beams. Especially in the case where the ceiling is triangular and has a bevel structure, the tensile force of the ropes helps to resist the downward or lateral displacement trend of the top beam due to gravity and external forces, which is beneficial to maintaining a relatively appropriate installation angle.

Specific embodiments

[0024] As Figures 1-9 shown, a pre-assembled structure for building construction includes a slide rail group 3 installed on a steel beam 1 and connecting pieces 4 installed at both ends of a top beam 2. A roller 400 is installed at one end of each connecting piece 4 away from the top beam 2. Several groups of rollers 400 roll in sequence from high to low along the slide rail group 3. The fixing part of the connecting piece 4 moves linearly along the slide rail group 3. The fixing part of the connecting piece 4 includes a fixing block 401 and a sliding piece 402 that are fixed to each other. The roller 400 is rotatably connected to the fixing block 401 through an inner shaft. The sliding piece 402 is slidably connected to the single slide rail 301, ensuring that the fixing part of the connecting piece 4 can move linearly along the single slide rail 301. There is a gap between the fixing block 401 and the single slide rail 301 to reduce the frictional resistance and facilitate the smooth sliding of the connecting piece 4. The rotating part of the connecting piece 4 includes a rotating shaft 403 and a fixing piece 404. One end of the rotating shaft 403 is fixed to the fixing piece 404, and the other end is rotatably connected to the fixing block 401. The fixing piece 404 is used to be fixed on the top beam 2 to keep the top beam 2 at a relatively appropriate installation angle for subsequent laying of plates. A through hole 7 is opened inside the top beam 2. A rope 8 is fixedly connected inside the through hole 7 of the top beam 2 at the lowest position. The rope 8 is slidably connected to the through holes 7 of the other top beams 2, which is beneficial to pulling several top beams 2 through the rope 8. The height of the through hole 7 is greater than the height of the rotating shaft 403 close to it. The contact surface between the sliding piece 402 and the single slide rail 301 is coated with lubricating oil. A notch is opened inside the fixing block 401. The positioning post 6 slides in the notch. The fixed end of the elastic sheet 9 is fixed to the notch, and its movable end is fixedly connected to the positioning post 6.

[0025] The slide rail group 3 includes two single slide rails 301. The two single slide rails 301 are symmetrically arranged and fixed on the steel beam 1. A number of positioning holes 5 are provided in the single slide rail 301. The number of positioning holes 5 are arranged at intervals along an inclined track. Positioning columns 6 are slidably installed at the fixing parts of a number of connecting pieces 4. When each positioning column 6 moves with the connecting piece 4, it will align with the corresponding positioning hole 5 on a preset track. The positioning column 6 crosses the non-target positioning hole 5, and the positioning column 6 is snapped into the target positioning hole 5 through an elastic piece 9.

[0026] As Figure 8 shown, a number of grooves 10 are provided in the single slide rail 301. The depression depth of the groove 10 is controlled within 1 mm - 3 mm. The width of the groove 10 is controlled to be equal to the diameter of the positioning hole 5. The length of the groove 10 is controlled to be 2 - 4 times the diameter of the positioning hole 5. Each groove 10 corresponds to the positioning hole 5 adjacent to it. When the positioning column 6 moves towards the corresponding positioning hole 5, it will first enter the corresponding groove 10, and then the positioning column 6 enters the positioning hole 5 along the groove 10. The groove 10 can guide the movement of the positioning column 6, and its shape is adapted to the head of the positioning column 6, and can be forcibly aligned by limiting when the positioning column 6 approaches the positioning hole 5. For example, when the connecting piece 4 slides along the single slide rail 301 to near the target positioning hole 5, the positioning column 6 will first contact the groove 10. The groove 10 and the positioning hole 5 should be coaxially arranged, and the positioning column 6 will be aligned with the center of the positioning hole 5 under the guidance of the inner wall of the groove 10, avoiding the positioning column 6 deviating from the target hole position.

[0027] Working principle:

[0028] In building construction, the traditional pre-assembled structure has problems of high risk of working at heights and low construction efficiency for the installation of the triangular hypotenuse ceiling top beam 2; when this pre-assembled structure is initially installed, the two single slide rails 301 of the slide rail group 3 are symmetrically fixed on the steel beam 1. Since the ceiling frame has an inclined surface structure, the slide rail group 3 can also be arranged obliquely along the inclined surface structure of the ceiling frame, fitting the hypotenuse structure of the ceiling; then the connecting pieces 4 are installed at both ends of the top beam 2. The rollers 400 at one end of the connecting piece 4 cooperate with the slide rail group 3, and the other end is connected to the top beam 2 through a rotating part; at this time, the lowermost top beam 2 is fixed by a rope 8, and the rope 8 passes through the through holes 7 inside each top beam 2 in sequence, as Figure 3 and Figure 4 shown, forming a suspension traction structure to ensure the stability of the top beam 2 during the installation process.

[0029] During the installation process, when installing the traditional triangular hypotenuse ceiling, the operators need to move frequently on the inclined and narrow operation surface to install the top beam 2. However, through the cooperation of the slide rail group 3 and the rollers 400, as Figure 3As shown in the figure, the operator can install the roller 400 on the slide rail group 3 while standing on the top of the ceiling. By using the self - gravity of the top beam 2, the top beam 2 slides along the slide rail, eliminating the need to walk back and forth on the unstable inclined plane, reducing the risk of unstable center of gravity and falling due to movement. The self - gravity of the top beam 2 and the cooperation between the roller 400 and the slide rail group 3 enable the top beam 2 to roll from a high place to a low place along the slide rail. During the movement of the connecting piece 4, the positioning column 6 of the fixing part moves synchronously with the connecting piece 4. Since the positioning holes 5 are arranged at intervals along an inclined track, when the positioning column 6 moves to align with the corresponding positioning hole 5 on the preset track, under the action of the elastic piece 9, the positioning column 6 automatically snaps into the target positioning hole 5, realizing the precise positioning and fixing of the top beam 2. When the positioning column 6 moves to a non - target positioning hole 5, the positioning column 6 is offset from the non - target positioning hole 5, allowing it to pass over the non - target positioning hole 5, avoiding mis - snapping and ensuring the smooth progress of the installation work. Finally, as Figure 1 shown, several pre - assembled structures are installed at the steel beam 1 frame.

[0030] The fixing part of the connecting piece 4 is composed of a fixing block 401 and a sliding piece 402. The roller 400 is rotatably connected to the fixing block 401 through an inner shaft. The sliding piece 402 is slidably matched with the single slide rail 301, and there is a gap between the fixing block 401 and the single slide rail 301. At the same time, lubricating oil or grease is applied to the contact surface between the sliding piece 402 and the single slide rail 301, reducing the sliding friction resistance. This enables the operator to easily push the top beam 2 to move on the slide rail with a relatively small thrust, reducing physical exertion and improving the installation efficiency. Moreover, the rotating part structure of the connecting piece 4 allows the top beam 2 to be adjusted in angle through the rotating shaft 403, facilitating the subsequent laying of plates according to the ceiling design requirements and improving the installation flexibility.

[0031] It should be noted that, as Figure 2 and Figure 3 shown, since the height of the through - hole 7 is greater than the height of the rotating shaft 403 close to it, and the top beam 2 has a tendency to rotate around the rotating shaft 403. An external force can be applied, such as by releasing the wire rope from the top through a winch, tightening one end of the rope 8, and keeping the rope 8 in a taut state. This can apply a pulling force to each top beam 2 and slowly release the rope 8 to make the roller 400 roll slowly, preventing the impact force from increasing due to too fast rolling. During the installation of several top beams 2, they are more stable, reducing the sway between the top beams 2. Especially in the case where the ceiling is triangular and has a bevel structure, the pulling force of the rope 8 helps to resist the downward or lateral movement tendency of the top beam 2 due to gravity and external forces, facilitating maintaining a relatively appropriate installation angle. When laying the plates on the top beam 2 later, it is convenient to fix the plates to the top beam 2. Moreover, the taut rope 8 can limit the movement range of the top beam 2, preventing the top beam 2 from suddenly slipping or swinging during the installation process and causing harm to the operator.
