Description

Safety railings for construction of building structures, building structures with safety railings and construction methods thereof

The present application relates to a safety railing, in particular to a safety railing used in the construction of a building structure, a building structure with a safety railing and a construction method thereof.

In the process of constructing the RC building structure, as the height of the floors increases, anti-fall facilities such as safety railings are an inevitable installation at the work site. They have the necessary protective effect on the workers to ensure that they are in the adjacent building structure. Construction safety at the edge prevents accidental work injuries caused by falling from heights. When constructing a building structure, protective railings are installed at the boundaries where the building structure needs to be prevented from falling (such as the outermost beam structure of the building structure, pits or patios). A conventional guardrail is composed of a plurality of vertical poles and, for example, a plurality of horizontal poles with both ends connected to the vertical poles. The bottom ends of each of the plurality of vertical poles are usually fixedly connected to a base plate. Workers usually fix the base plate to the floor surface where the safety railings are to be installed by using fasteners such as steel nails or screws, and the vertical poles are also fixed to the floor surface. Then the workers install a plurality of crossbars respectively. A plurality of vertical poles are placed adjacent to each other to complete the setting of the safety railing.

However, these conventional safety railing installation methods are not only labor-intensive and time-consuming when fixing the poles to the surface of the construction floor, but also increase the installation time and relatively reduce the efficiency of constructing the building structure. In building construction operations, safety railings need to be installed When carrying out specific operations (such as continuing the column structure of a completed building structure), it takes time to dismantle the safety railings before the required construction operations can be carried out. Finally, because the safety railing poles are usually fixed on the surface of the floor to be constructed, when the safety railing is no longer needed, it takes time to remove the base plates of the fixed poles one by one. Therefore, the structure and use of the conventional safety railings are not only time-consuming and labor-intensive, but also cannot effectively shorten the total construction time of the building and reduce the labor and time costs.

In view of the above shortcomings of the conventional safety railings, this application proposes a safety railing and a construction method that not only facilitate the rapid assembly and disassembly of the safety railing, but also have the effect of elastically adjusting the length of the crossbar of the safety railing, so as to meet the above needs. When a specific operation is performed at the location of the safety railing, the safety railing can be quickly and manually adjusted without hindering the specific operation.

One purpose of this application is to provide a safety railing structure that can elastically adjust the length of the safety railing's crossbar, thereby facilitating the specific structural construction of the building structure.

FIG. 2D shows a top view of the sleeve member of FIG. 2A , and FIG. 2D also shows a schematic diagram of the structural dimensions of a main pole of a safety railing inserted into the sleeve of the sleeve member. As can be seen from Figure 2D, the sleeve S1 of the sleeve member S with a rectangular cross-section can accommodate one of the main poles P1 of the safety railing in its hollow space S3. The outer circumferential length and outer circumferential width of the sleeve S1 can be, for example, 50 mm.

Figure 3A shows a schematic structural diagram of the building structure in Figure 1 after the floor layer has been poured. The building structure 1 shown in Figure 3A is derived from the building structure shown in Figure 1 by setting formwork and pouring concrete on a plurality of column structures 2, a plurality of half beams 3, each small beam 4 and each steel corrugated plate. The casting operation above 5 is to form the first floor floor 6 and a plurality of beam structures 3" flush with the floor floor 6 to form the same surface. It should be noted that after the casting operation for pouring concrete is completed, the semi-preparatory The plurality of stirrups 32 with hooks of each of the cast beams 3 are covered with concrete, and a part of the plurality of continuous column bars 22 of each of the plurality of column structures 2 still has protrusions after the floor plate 6 is completed. A portion outside the top surface 61 of the floor board 6 is exposed to the top surface 61 of the floor board 6 through the opening S4 of each of the sleeve members S.

According to the structures shown in Figures 1 and 3A, it can be seen that the floor slab 6 is completed by casting operations. Therefore, after the casting operation of the floor slab 6 is completed by pouring concrete on each half-joist beam 3, a cast portion 3' is formed above each of the half-john beams 3, whereby each half-joist beam 3 is in line with the cast part formed on the floor 6. The corresponding casting portions 3' thereon together form respective beam structures 3". In other words, in Figure 3A, each of the beam structures 3" includes a half beam 3 and a beam above the half beam 3. Field cast section 3'. Since in Figure 1, the two ends of each half beam 3 are arranged on the edges of two adjacent column structures 2 of the plurality of column structures 2, therefore after the casting operation of pouring concrete is completed, the plurality of Two adjacent column structures 2 of a column structure 2 are also respectively located at both ends of one of a plurality of beam structures 3" and support the beam structure 3".

Based on the above, the two-point chain line shown in FIG. 3A divides the floor 6 into different areas such as the casting part 3' of the beam structure 3, the floor surface 61, and the column reinforcement connection area A.

In addition, since a plurality of sleeve members S have been pre-set and fixed in the half-rib beam 3 along one of the length directions (or the first direction D1) of each half-rib beam 3, the casting operation is completed. Finally, the sleeve S1 of each sleeve member S is also embedded in the cast-in-place portion 3', and only the opening S4 of each sleeve member S is exposed at the top of the cast-in-place portion 3' of the beam structure 3" On the surface. Therefore, each of the beam structures 3" formed after the pouring operation includes a plurality of pre-embedded sleeve pieces S arranged in the beam at intervals along one of its length directions (or the first direction D1). In the structure 3" (it should be noted that since the cast part 3' above the half beam 3 and the floor slab 6 are poured by the same concrete pouring operation, the top surface of the completed beam structure 3" is different from the The top surface 61 of the floor 6 is coplanar).

It is worth mentioning that, according to the embodiment shown in FIGS. 1 and 2B , there is a gap distance G between the bottom surface of the sleeve S1 of the sleeve member S and the top surface 31 of the half-rail beam 3 . As shown in Figure 4, the gap distance G is used to allow an L-shaped metal template M to be inserted therein, and the flat bottom wall of the L-shaped metal template M faces outward from the inside of the bottom surface S5 of the sleeve S1 of the sleeve member S. Extend, and then serve as part of the formwork for the concrete pouring operation on the floor 6, so that after the casting operation of the floor 6 is completed, it has a part extending outward from the outer edge of the beam structure 3". In other words, as long as it is set In the structural state where there is a gap distance G between the bottom surface of the sleeve S1 of the tube S and the top surface 31 of the half-barrel beam 3, after the floor casting operation, the structure shown in Figure 3A and Figure 4 can be completed. Shows the structural form of the floor 6 with a portion extending outward from the beam structure 3".
