Problems solved by technology

[0002] In some projects, the net distance between the basement outdoor shear wall and the support pile is relatively close (within 400mm), and when the external wall formwork is constructed, workers cannot enter this narrow space to support the formwork
Therefore, the difficulty of construction is greatly increased. At this time, we can consider setting up a single-side formwork support method on the inner side of the outer wall. However, in the actual construction process, the single-side formwork is very likely to cause the possibility of mold explosion, mold expansion, or even mold collapse. , with unpredictable quality and safety risks

Embodiment 1

[0034] Embodiment one, as figure 1 with figure 2 As shown, a construction structure of exterior walls in a narrow basement space includes exterior wall reinforcement skeletons, rafts 2, inner support systems 3 and support piles 4, exterior wall reinforcement skeletons are arranged around exterior wall area 1; at the bottom of the outer wall area 1; the inner support system 3 is set on the inner side of the outer wall area 1; the support pile 4 is set on the outer side of the outer wall area 1; The outer support system 5 includes a plurality of channel steels 51, and the plurality of channel steels 51 are vertically arranged between the outer wall area 1 and the support piles 4.

[0035] A plurality of vertical channel steels 51 are preferably equidistantly arranged between the outer wall area 1 and the support piles 4. The equidistant arrangement of the plurality of channel steels 51 can ensure that each channel steel 51 is stressed when pouring the outer wall concrete. Sam...

Embodiment 2

[0042] Embodiment 2. A construction method for an exterior wall in a narrow basement space, comprising the following steps:

[0043] Step S1: setting the outer support system 5 on the outer side of the outer wall area 1;

[0044] Step S2: installing the outer wall reinforcement skeleton around the outer wall area 1;

[0045] Step S3: setting the inner support system 3 on the inner side of the outer wall area 1 .

[0046] Preferably, the specific implementation of step S1 is:

[0047] Step S11: set a crown beam 52 on the upper end of the support pile 4, and set a concrete anti-sill 53 corresponding to the outer wall area 1 on the raft 2;

[0048] Step S12: Set a plurality of vertical channel steels 51 between the outer wall area 1 and the support piles 4, and fix the upper ends of the plurality of channel steels 51 on the crown beam 52, and the lower ends of the plurality of channel steels 51 Set on the concrete anti-sill 53;

[0049] Step S13 : setting multiple water-stop sc...

Abstract

The invention relates to a basement narrow space outer wall construction structure and method. The construction structure comprises an outer wall steel bar framework, a raft plate, an inner side supporting system and support piles, wherein the outer wall steel bar framework is arranged on the periphery of an outer wall area; the raft plate is arranged at the bottom of the outer wall area; the inner side supporting system is arranged on the inner side of the outer wall area; and the support piles are arranged on the outer side of the outer wall area. The basement narrow space outer wall construction structure further comprises an outer side supporting system arranged on the outer side of the outer wall area. The outer side supporting system comprises a plurality of pieces of channel steel vertically arranged between the outer wall area and the support piles. The outer side supporting system is arranged between the outer wall area and the support piles. The outer side supporting system and the inner side supporting system are connected into a whole to jointly resist lateral pressure formed in the outer wall concrete pouring process, and the outer wall construction quality can be guaranteed. The cost is low, and the basement narrow space outer wall construction structure and method are suitable for all similar narrow space formwork erecting projects.

Description

technical field [0001] The invention relates to the technical field of building civil construction, in particular to a construction structure and a construction method for an exterior wall in a narrow basement space. Background technique [0002] In some projects, the net distance between the basement outdoor shear wall and the support pile is relatively close (within 400mm), and when the external wall formwork is being constructed, workers cannot enter this narrow space to support the formwork. Therefore, the difficulty of construction is greatly increased. At this time, we can consider setting up a single-side formwork support method on the inner side of the outer wall. However, in the actual construction process, the single-side formwork is very likely to cause the possibility of mold explosion, mold expansion, or even mold collapse. , with unpredictable quality and safety risks. Contents of the invention [0003] The technical problem to be solved by the present inven...
