Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention comprises the following steps: please refer to fig. 1, a unilateral formwork construction device of basement outer wall, including pre-buried steel sheet 7 on basement foundation slab and a set of bar planting 4 of implanting the basement lateral wall in advance, template 6 has been arranged to basement lateral wall one side, 6 outside template vertically be arranged with a set of flitch 5, arrange a set of double steel pipe 10 on flitch 5 is improved level, the welding has a set of upright muscle 9 on pre-buried steel sheet 7, and upright muscle 9 is binded fixedly through the bundle silk with bar planting 4, the outer end of bar planting 4 and the one end welded fastening of stagnant water screw rod 11, stretch out from between the double steel pipe 10 after the other end of stagnant water screw rod 11 passes template 6, the end that stretches out of stagnant water screw rod 11 is fixed through nut fastener 3. A water stop steel plate 1 is arranged between the bottom of the template 6 and the basement foundation bottom plate, and water seepage at the root of the basement outer wall is avoided. Because the unilateral formwork region can not be made traditional waterproofing, consequently lay waterproofing membrane 8 on the basement lateral wall, avoid basement lateral wall infiltration. The battens 5 are supported by the inclined struts 2, so that the stability of the template 6 is improved, and the phenomena of mold explosion, slurry leakage and the like during concrete pouring are avoided.
When the unilateral formwork erecting construction device for the basement exterior wall is adopted for constructing the basement exterior wall, firstly, an embedded steel plate 7 is embedded in a basement foundation bottom plate, a waterproof coiled material 8 is laid on the side wall of the basement, then a group of planting bars 4 are implanted into the side wall of the basement for fixing, meanwhile, a group of vertical bars 9 are welded on the embedded steel plate 7, the vertical bars 9 and the planting bars 4 are bound and fixed through binding wires, and then the outer ends of the planting bars 4 and one end of a water stop screw 11 are welded and fixed; at the moment, a template 6 is arranged on one side of the side wall of the basement, a water stop steel plate 1 is arranged at the bottom of the template 6, a group of battens 5 are vertically arranged on the outer side of the template 6, a group of double-row steel pipes 10 are horizontally arranged on the battens 5, the other end of a water stop screw rod 11 penetrates through the template 6 and then extends out of the double-row steel pipes 10, and the extending end of the water stop screw rod 11 is fixed through a nut fastener 3, so that the template installation and fixation can be completed; and finally, pouring the concrete of the outer wall of the basement, and removing the formwork after the concrete reaches the design strength.
The waterproof roll 8 is fixed on the side wall of the underground chamber by adopting a pre-laying and reverse-sticking method.
And after the basement outer wall is formed, backfilling and reinforcing the basement side wall by using the same-grade concrete.
In conclusion, the efficient construction and quality control of the outer wall of the basement can be realized in the narrow side wall area of the basement by adopting the mode of the unilateral formwork support, and the problems of insufficient space, long construction period, construction difficulty and the like in the traditional bilateral formwork support are solved. In the unilateral formwork construction process of basement lateral wall, artifical construction convenience is swift, practices thrift template material, consolidates whole template support system through stagnant water bolt and bracing, and the reinforcement measure is directly perceived effective, and template support system is firm safety, and maneuverability is stronger. The invention is suitable for the basement exterior wall construction of the cast-in-place pile enclosure structure in the basement narrow space.
