Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a fixing device for reserved holes in H-shaped horizontal cable trays. Background Technology

[0002] Currently, the real estate industry is experiencing a downturn, and construction projects are facing significant challenges. To improve construction quality, shorten construction periods, and reduce delivery difficulties, as well as to increase the turnover of materials and tools during construction, reduce construction costs, and conserve resources, real estate companies across the country are using aluminum formwork and aluminum-plastic composite formwork for high-rise buildings and similar multi-story and low-rise buildings. This aims to improve construction quality and efficiency. However, the formwork needs to be pre-reserved for electrical cable trays, wiring, etc. Currently, most projects use aluminum or aluminum-plastic composite formwork for overall formwork, with pre-reserved openings made of extruded polystyrene board, foam board, or wooden boxes. However, pre-reserving electrical cable trays, wiring, and water pipe openings on such standardized formwork is difficult, requiring repositioning each time, and it's impossible to guarantee that the pre-reserved openings will always be in the same location, leading to significant rework later. Therefore, there is an urgent need to find a method or process that can accurately locate and ensure the precise placement of pre-reserved openings, reducing rework costs later.

[0003] Currently, during construction, for the reservation of holes for electromechanical cable trays, electrical holes, etc., most projects use aluminum formwork or aluminum-plastic formwork for the overall formwork, and use extruded polystyrene board, foam board, wooden boxes, etc. for the reservation. However, the accuracy of the reservation is poor, resulting in a large amount of rework later. In addition, aluminum formwork requires a lot of drilling, which reduces turnover. Each floor needs to be repositioned, and the opening is significantly misaligned. After pouring, disassembly is difficult, and wooden boxes are easily damaged. Each floor needs to make wooden boxes, position and fix them before the reservation of the opening is completed. Utility Model Content

[0026] Example 1

[0027] This embodiment provides, for example Figures 1-3 The H-shaped horizontal cable tray reserved hole fixing device shown includes a casting template 1, a positioning device 2 fixedly installed on the casting template 1, and a base plate 3. The casting template 1 is a template used for floor casting, the positioning device 2 is installed on the casting template 1, and the base plate 3 is the basic structure of the positioning device 2.

[0028] Multiple positioning holes 4 are provided on the upper surface of the base plate 3. The positioning holes 4 are used to install the positioning device 2 on the casting template 1 and to strengthen the connection.

[0029] A snap-fit ​​component 5 is fixedly installed on the upper end face of the base plate 3. The snap-fit ​​component 5 is a positioning structure for the installation of the box 8 to be reserved later.

[0030] A central hole 6 is provided at the center of the upper surface of the base plate 3. An additional central hole 6 is provided at the center of the base plate 3 to further position and install the reserved box 8, thereby increasing the reliability of the structure.

[0031] Furthermore, such as Figure 2 As shown, the base plate 3 consists of two horizontal plates 31 and one vertical plate 32, with the vertical plate 32 fixedly disposed between the two horizontal plates 31;

[0032] The two horizontal plates 31 are parallel to each other, and the vertical plate 32 is perpendicular to the horizontal plates 31. The vertical plate 32 is located at the center of the base plate 3. The two horizontal plates 31 and one vertical plate 32 form an H-shaped base plate 3. While ensuring structural reliability, this design saves material waste and also provides enough space for the installation of other components.

[0033] Furthermore, the positioning holes 4 are located on the horizontal plate 31 and are arranged in a centrally symmetrical manner. There are a total of four positioning holes 4, that is, there are two positioning holes 4 on each horizontal plate 31. The centrally symmetrical positioning holes 4 make the connection between the base plate 3 and the casting template 1 more reliable and stable, and the positioning device 2 is less likely to shift during repeated use of the fixing device.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, the snap-fit ​​assembly 5 includes four L-shaped positioning plates 51. The positioning plates 51 are vertically arranged at both ends of the horizontal plate 31 and are vertically installed on the horizontal plate 31. The openings of the positioning plates 51 all face the center hole 6.

[0035] The positioning plates 51 are set at the four corners of the base plate 3. By welding L-shaped positioning plates 51 at the four corners of the base plate 3 and installing them symmetrically with the center hole 6 as the center, a space is formed between the snap-fit ​​components 5 to place the reserved box 8. The reserved box 8 can be snapped onto the base plate 3 to ensure that the reserved box 8 will not change position during the pouring process and to ensure the accuracy of the opening position.

[0036] Furthermore, the center hole 6 is opened at the center of the vertical plate 32, and a vertical mounting rod 7 is fixedly installed at the center hole 6. The mounting rod 7 passes through the center of the reserved box 8. After the reserved box 8 is inserted through the mounting rod 7, the reserved box 8 can be directly tightened on the mounting rod 7 with a nut. By adding the additional mounting rod 7, the positional accuracy of the reserved box 8 is further ensured, making it less likely for the reserved box 8 to shift during the pouring process and affect the size and position of the opening, thereby reducing the possible rework impact later.

[0037] When in use: On the casting template 1, confirm the accurate position of the reserved opening and draw a pattern. After confirming the position of the opening, place and install the positioning device 2 at the drawn pattern. After the initial positioning is completed, connect the positioning device 2 to the casting template 1 through the positioning hole 4 on the base plate 3 with threads to complete the assembly of the casting template 1 and the positioning device 2.

[0038] After completion, install the mounting rod 7 at the center hole 6, pass the reserved box 8 through the mounting rod 7 and place it in the positioning device 2, and ensure that the reserved box 8 can be snapped into the snap-fit ​​component 5. Then tighten the reserved box 8 with bolts to complete the assembly of the entire fixing device.

[0039] After the floor is poured, the entire fixing device can be demolded directly without having to remove each component in stages. The installation and pouring of the next floor can then proceed. The entire fixing device has a simple and reliable structure, which can greatly reduce the construction period. The fixed opening position also avoids the rework caused by the difference in the opening position of each floor. The simple structure also allows for quick replacement if some structural damage occurs during reuse, so that the work can continue.

[0040] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
