Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a supporting mechanism used in building construction. Background Art

[0002] In the process of house construction, molds are often used for casting construction. Specifically, a pre-designed specific mold is installed at the corresponding position of the building structure. Usually these molds are made of high-strength materials and have precise size and shape. Then, concrete and other building materials are poured into the mold. Under the constraint of the mold, the concrete gradually solidifies and forms various structural components required for house construction, such as columns, beams, floor slabs, etc. The use of mold casting can realize the standardization and standardization of building structures and ensure the dimensional accuracy and quality stability of each component. At the same time, this method can improve construction efficiency, reduce errors and uncertainties caused by manual operation, and can flexibly adjust the shape and size of the mold according to different building design requirements to meet diverse building needs. In addition, mold casting is also conducive to achieving energy conservation and environmental protection of buildings, reducing the waste of building materials and the generation of construction waste.

[0003] The longitudinal load-bearing module occupies an important position in house construction. It is mainly composed of a longitudinal load-bearing beam mold and two load-bearing column molds. The longitudinal load-bearing beam mold is mainly used to cast the longitudinal beams of the house, and the load-bearing column mold is used to cast the columns of the house. However, in actual applications, the longitudinal load-bearing beam mold only relies on two load-bearing column molds to bear the load together, and the stability is obviously insufficient. Once external environmental factors such as wind force, concrete pressure, and slight collisions during construction occur, the longitudinal load-bearing beam mold and the load-bearing column mold will have a greater impact, causing the stability of the overall structure to be further reduced, and it is difficult to maintain the correct position and shape. Ultimately, this will not only have an adverse impact on the subsequent construction quality and safety, but also reduce the efficiency of construction and the reliability of the project, bringing many challenges to house construction.

[0041] The support mechanism of the present application is applied to the longitudinal bearing module and plays an important role. Among them, through the cooperation of the first support rod 1, the first threaded rod 2 and the base 3, the connection between the longitudinal bearing beam mold 7 and the ground is successfully established. This connection has a significant supporting effect on the longitudinal bearing beam mold 7, so that the stability of the longitudinal bearing beam mold 7 is effectively guaranteed when pouring concrete. In addition, with the cooperation of the first threaded rod 2 and the first threaded groove, the height of the first support structure can be flexibly adjusted, so as to meet the support requirements of the longitudinal bearing beam mold 7 of different heights, and the scope of use is wider and more practical. Further, the connection between the longitudinal bearing beam mold 7 and the first bearing column mold 8 is established by the first support rod 1, and the two are connected as one, which greatly improves the stability of the connection between the two, and also strengthens the structural stability of the longitudinal bearing beam mold 7. Similarly, the connection between the longitudinal bearing beam mold 7 and the second bearing column mold 9 is established by the second support rod 11, and the two are also connected as one, which improves the connection stability and further strengthens the structural stability of the longitudinal bearing beam mold 7.

[0054] The second distance adjustment component includes a third threaded rod 1105, a second connecting piece 1106 and a second bolt group 1107. One end of the second threaded rod 1102 is threadedly engaged with the second thread groove, and the other end passes through the second thread groove and is connected to the second connecting piece 1106. The second bolt group 1107 is arranged on the second connecting piece 1106.

[0055] In the above embodiment, the first connecting member 1103 cooperates with the first bolt group 1104 to realize the detachable connection between the support rod shaft 1101 and the longitudinal load-bearing beam mold 7. Similarly, the cooperation between the second connecting member 1106 and the second bolt group 1107 can realize the detachable cooperation between the support rod shaft 1101 and the first load-bearing column mold 8 or the second load-bearing column mold 9. In addition, through the threaded cooperation between the second threaded rod 1102 and the second thread groove and the threaded cooperation between the third threaded rod 1105 and the third thread groove, the length of the second support rod 11 and the third support rod 12 can be adjusted. Such a design is suitable for positioning and installation at different spacings, greatly increases its scope of use, has strong practicality, and brings great convenience to construction.

[0056] In some embodiments of the present invention, the first connecting member 1103 and the second connecting member 1106 are both provided with stepped installation slots, and the small-diameter end of the installation slots faces the outside of the first connecting member 1103 or the outside of the second connecting member 1106;

[0057] The second threaded rod 1102 and the third threaded rod 1105 are both provided with a connecting block 21, and the connecting block 21 is rotationally matched with the installation notch.

In addition, since the caliber value of the second guide block 15 is greater than the caliber value of the second thread groove, the second threaded rod 1102 can be effectively prevented from falling off from the second thread groove. In this way, the second threaded rod 1102 and the support rod body 1101 are connected as one body, thereby improving the overall structural stability.

[0062] In some embodiments of the present invention, a third guide groove 17 is provided at the bottom of any of the third thread grooves, and the third guide groove 17 is provided along the axis direction of the support rod shaft 1101;
