[0035] As Figure 2 , Figure 3 and Figure 4 shown, in some embodiments, in order to enable the two filling strips 2 to be stably inserted and positioned in the through pipe 1, the keel for building formwork further includes a spacing block 3, the spacing block 3 is arranged between the two filling strips 2, and the spacing block 3 is staggered with the through hole 11, so that the filling strip 2 is closely connected to the inner side wall of the through pipe 1 through the arrangement of the spacing block 3, specifically, the filling strip 2 and the through pipe 1 are in good contact to form frictional resistance through the interference fit between the filling strip 2 and the through pipe 1, so that the filling strip 2 is not easy to slip out relative to the through pipe 1. More specifically, the spacing block 3 has a plurality of spacing blocks 3, the plurality of spacing blocks 3 are distributed at intervals along the length direction of the through pipe 1, specifically, a plurality of through holes 11 are arranged at intervals on the through pipe 1, the through holes 11 and the spacing blocks 3 are arranged in a staggered manner, so that the spacing blocks 3 and the through holes 11 do not interfere with each other. It can be understood that, as a preferred embodiment, the spacing block 3 can be fixedly connected to the filling strip 2, the spacing block 3 and the two filling strips 2 are connected and then inserted into the through pipe 1, and the spacing block 3 can be connected to the filling strip 2 by bonding, riveting or other fixing methods; in some other embodiments, the spacing block 3 can be fixedly connected to the through pipe 1 by bonding, riveting or other fixing methods, and the filling strip 2 is separately inserted into the through pipe 1.
[0036] As Figure 3As shown, in some embodiments, the inner cavity cross-section of the through tube 1 is a rectangular structure, and the cross-sectional area of the filling strip 2 is less than half of the inner cavity cross-sectional area of the through tube 1, so that when the two filling strips 2 are inserted into the inner cavity of the through tube 1, a gap 4 is left for the through hole 11 to pass through.
[0037] like Figure 1 As shown, in some embodiments, a weight-reducing hole 12 is provided on the side wall of the through pipe 1. The setting of the weight-reducing hole 12 can play a role in weight reduction. In addition, the filling strip 2 is at least partially exposed to the weight-reducing hole 12, so that the filling strip 2 can be constructed through the weight-reducing hole 12.
