Abstract
The invention discloses an external wall neck construction method of the underground cast-in-situ concrete structure, which includes the following steps: (1) arranging reinforced bars, wall body external steel bars and wall body internal steel bars on a bedding course, arranging a first exterior sheathing composed of a multilayer board and a square timber outside the wall body external steel bars in the method of external suspended form supporting formwork; (2) arranging the first exterior sheathing composed of the multilayer board and the square timber inside and fixedly connecting with the wall body internal steel bars, arranging a water-stopping steel plate between the wall body external steel bars and the wall body internal steel bars; (3) casting the concrete and finishing the underground cast-in-situ concrete structure external wall neck construction. The method enables a calendering operation of the upper surface of a foundation plate through surface rolling mechanically or manually, and enables the wall foot of the wall neck to be conveniently rolled to achieve the process requirement of one-step operation of casting and rolling together and the effect of exposed concrete. The method is easy, practical and economic, and the flatness can be controlled.
Description
Technical field
The invention belongs to building engineering field, particularly relate to a kind of underground cast-in-place concrete structure outer wall neck construction method.
Background technology
Underground cast-in-place concrete structure outer in construction owing to require between the operation and the requirement of waterproof, when carrying out the construction of underground foundation base plate, adopt following method by the current specifications requirement: the upper surface at sole plate is kept somewhere the high wall neck (Fig. 1) of 300mm, the upper surface of wall neck is a horizontal construction joint, mould mold method (Fig. 2) is hung in the employing that is provided with of wall neck, promptly the template of forming by composite board, the lumps of wood by scaffold tubes prop up be located at base plate reinforcing bar top after, fluid concrete makes underground foundation base plate and the one-shot forming of wall neck.
The method of keeping somewhere the wall neck by prior art, because template need support with scaffold tubes in inner side of outer wall, template and scaffold tubes occupy certain space, the upper surface that makes sole plate is during by mechanical or manual floating calendering operation, the foot of a wall portion of wall neck can't be floating, can't accomplish the technological requirement that once survives with smearing with building.Since more and more higher to the concrete wall surface standard-required in recent years, reach the clear-water concrete effect.So very high to its impression planeness requirement, particularly ground, the metope to large-scale basement requires one-shot forming, reach the clear-water concrete standard, and ground flat degree is not more than the 2mm accuracy standard.Existing formwork support process by code requirement is difficult to reach designing requirement.
Summary of the invention:
The objective of the invention is to overcome deficiency of the prior art, a kind of underground cast-in-place concrete structure outer wall neck construction method is provided.
Technical scheme of the present invention is summarized as follows:
A kind of underground cast-in-place concrete structure outer wall neck construction method comprises the steps:
(1) the inboard reinforcing bar of reinforcement foundation, wall outer side reinforcing bar and body of wall is set on bed course, hangs first exterior sheathing that the method setting of mould formwork is made up of composite board, the lumps of wood with external application at the wall outer side reinforcing bar;
(2) will be arranged on by first inner formword that composite board, the lumps of wood are formed in the inboard reinforcing bar of body of wall, and fixedly connected, between outside reinforcing bar and the inboard reinforcing bar of body of wall, steel plate for sealing water will be set with the inboard reinforcing bar of body of wall;
(3) concreting is finished the underground cast-in-place concrete structure outer wall neck construction.
Method of the present invention can make the upper surface of sole plate by mechanical or manual floating calendering operation, and the foot of a wall of wall neck can be convenient floating, accomplishes the technological requirement that once survives with smearing with building.Reach the clear-water concrete effect.Method of the present invention is simple, practical, and economy, planeness reach controlled.

Fig. 2 installs concrete exterior wall wall neck template method schematic diagram for existing method;
Fig. 3 installs concrete exterior wall wall neck template schematic diagram for method of the present invention;
Fig. 4 is a formwork erection method schematic diagram for the inventive method pouring concrete exterior wall;

The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Sole plate that existing method shown in Figure 1 is built and outer wall neck schematic diagram are among the figure: wall outer side reinforcing bar 1; The inboard reinforcing bar 2 of body of wall; Steel plate for sealing water 3; Outer wall neck 4; Sole plate 5; Bed course 6.
Make underground foundation base plate and the one-shot forming of wall neck, prior art adopts the method for hanging the mould formwork, sees Fig. 2, among the figure: reinforcement foundation 10, scaffold tubes 9, the first inner formwords 16, the first exterior sheathings 17, inside and outside template is made up of composite board, the lumps of wood.
A kind of underground cast-in-place concrete structure outer wall neck construction method of the present invention comprises the steps: (see figure 3)
(1) the inboard reinforcing bar 2 of reinforcement foundation 10, wall outer side reinforcing bar 1 and body of wall is set on bed course 6, hangs first exterior sheathing 17 that the method setting of mould formwork is made up of composite board, the lumps of wood (external application hang the mould formwork method be to support first exterior sheathing 17) at the wall outer side reinforcing bar with external application by scaffold tubes 9;
(2) will be arranged on by first inner formword 16 that composite board, the lumps of wood are formed in the inboard reinforcing bar of body of wall, and fixedly connected, between outside reinforcing bar and the inboard reinforcing bar of body of wall, steel plate for sealing water 3 will be set with the inboard reinforcing bar of body of wall;
(3) concreting is finished the underground cast-in-place concrete structure outer wall neck construction.Because first inner formword is arranged in the inboard reinforcing bar of body of wall, makes the sole plate upper surface not have any supporter, when building, sole plate upper surface mechanical trowelling machine easy to use carries out floating press polish, has improved operating efficiency.
After finishing the underground cast-in-place concrete structure outer wall neck construction, remove first inner formword and first exterior sheathing, carry out the top wall construction, the method of its formwork is seen Fig. 4, second inner formword 12 is directly upright to the sole plate upper surface by the inside wall line, second inner formword, second exterior sheathing 13 are fixed by scaffold tubes 9 and through-wall bolt 14, build again.After removing the second inside and outside template, the anhydrous flat constuction joint of inboard metope (existing method has inboard metope that horizontal construction joint is arranged), the surface is the impression unanimity up and down.See Fig. 5, among Fig. 5, build sole plate 15 and wall neck for the first time, for the second time concreting wall 18.
