Embodiment 1

[0043] Please check figure 1 , a method of reverse basement exterior wall construction, which comprises:

[0044] Step 1, for the construction of the top and bottom plates, the top plate 10 has a downwardly facing upper boss 11, and the bottom plate 20 has an upwardly facing lower boss 21;

[0045] Step 2, for installing the wooden formwork 30 for the side wall, the wooden formwork 30 surrounds the outer cylindrical surface of the upper boss 11 and the outer cylindrical surface of the lower boss 21;

[0046] Step 3, for installing the first water stop plate 41 on the wooden formwork 30, pouring concrete in the section between the upper boss 11 and the first water stop plate 41 in the wooden formwork 30, and forming the upper section of concrete 51, The upper concrete 51 is connected with the upper boss 11;

[0047] Step 4, for installing the corbel 60 on the wooden formwork 30, the port of the corbel 60 is higher than the first water stop plate 41, and the second water stop ...

Embodiment 2

[0054] The difference between this embodiment and the previous preferred embodiment is that the step 5 includes:

[0055] Step 51, for pouring concrete to the part above the second water stop plate in the wooden mold, and forming the first lower section of concrete, and the first lower section of concrete and the lower bump are connected as one;

[0056] Step 52, for using the corbel to pour concrete into the section between the first lower section concrete and the upper section concrete in the wooden form, and forming the second lower section concrete, the second lower section concrete, the first lower section concrete and the upper section Concrete molding.

Embodiment 3

[0058] The differences between this embodiment and the previous preferred embodiment are:

[0059] A construction method for a basement exterior wall by the reverse method, comprising:

[0060] Step 1, for constructing the top and bottom plates, the top plate has a downwardly facing upper boss, and the bottom plate has an upwardly facing lower boss;

[0061] Step 2, for installing the side wall wooden formwork, the wooden formwork is surrounded by the outer cylinder surface of the upper boss and the outer cylinder surface of the lower boss;

[0062] Step 3, for installing the corbel on the wooden formwork, and installing the second water stop plate on the lower boss;

[0063] Step 4, for installing the first water stop plate on the wooden formwork, the first water stop plate is lower than the port of the corbel, and the part between the upper boss in the wooden formwork and the first water stop plate is poured with concrete , and formed into the upper section of concrete, an...

Abstract

The invention discloses a topdown construction method of a basement exterior wall, comprising the following steps of: constructing a top plate and a bottom plate, wherein the top plate is provided with a downward upper lug boss, and the bottom plate is provided with an upward lower lug boss; installing a side wall wood mould, wherein the side wall wood mould leans against the outer cylindrical surface of the upper lug boss and the outer cylindrical surface of the lower lug boss in an enclosing way; installing a first water stop plate on the side wall wood mould, and pouring concrete into a part of segments positioned between the upper lug boss inside the side wall wood mould and the first water stop plate, and forming into upper-segment concrete, wherein the upper-segment concrete is connected with the upper lug boss into a whole; arranging a corbel on the side wall wood mould, wherein a port of the corbel is higher than the first water stop plate, and the lower lug boss is provided with a second water stop plate; and pouring the concrete into a part of segments positioned between the upper-segment concrete inside the side wall wood mould and the second water stop plate by utilizing the corbel, and forming into lower-segment concrete, wherein the lower-segment concrete, the upper-segment concrete and the lower lug boss are connected into a whole. The invention has the advantages of being beneficial to preventing of the water seepage of an exterior wall integer and controlling the contraction.

Description

technical field [0001] The invention relates to a method for constructing an exterior wall of a basement by a reverse method. Background technique [0002] The existing construction method of the basement exterior wall of the reverse method includes: step 1, for constructing the top and bottom plates, the bottom surface of the top plate and the top surface of the bottom plate are both plane; step 2, for installing the wooden formwork of the side wall, the wooden formwork Embedding the grouting pipe inside; step 3, adopting high-pressure grouting treatment technology through the pre-embedded grouting pipe, pouring concrete at one time, and forming the concrete. This construction method has the following disadvantages: 1. Water seepage is easy between the side wall and the roof and the bottom plate; 2. One-time construction, the shrinkage of the side wall is not easy to control. Contents of the invention [0003] The invention provides a construction method of the basement ...
