During the layering process, when installing the formwork of the upper bin number, artificial splicing of the formwork is often carried out at the joint position, which is extremely easy to cause loose joints with gaps, the formwork not being fully attached to the lower-layer concrete, affecting subsequent concrete pouring, resulting in slurry leakage, honeycombing and stepped joints on the concrete surface, and in severe cases, holes and exposed reinforcement, etc. Moreover, the traditional construction method has an extremely slow construction speed, so a formwork installation auxiliary device is needed to avoid the above situations. Summary of the Utility Model:

[0003] In view of the above problems, the purpose of the utility model is to provide a formwork installation auxiliary device to solve the problems of loose joints and low construction efficiency during the installation of the layered construction joint formwork.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

The upper bin number formwork is vertically inserted into the empty groove formed by multiple installation notches of the square timbers and the side surface of the lower-layer concrete and clamped, and the upper bin number formwork is closely attached to the side surface of the lower-layer concrete.

[0006] The square timber is of a cuboid structure, horizontally arranged transversely. An installation notch penetrating along the length direction of the cuboid structure and opening upward is opened at one corner on the side of the cuboid structure close to the side wall of the lower-layer concrete.

[0007] The sizes of all the square timber structures are the same, the sizes of the installation notches opened thereon are the same, and the positions and sizes of the through holes opened thereon are the same.

[0008] The cross-section of the installation notch opened on the square timber is L-shaped, and the cross-section of the empty groove formed by the L-shaped installation notch and the side surface of the lower-layer concrete is U-shaped.

[0009] The width of the installation notch on each square timber is the same as the thickness of the upper bin number template, that is, the width of the empty groove formed by the installation notch of each square timber and the side of the lower-layer concrete is the same as the thickness of the upper bin number template, and the upper bin number template is clamped into it.

[0010] The depths of the installation notches on each square timber are the same, and the depth of the installation notch can be adjusted according to the size change of the upper bin number template.

[0022] See Figures 1-3, the present utility model provides an auxiliary device for installing the upper formwork of the side wall stratified construction joint. The device includes a square timber 1, a tie rod 2, and an upper bin formwork 3. Multiple square timbers 1 are arranged along the same horizontal line on the side surface of the lower layer of concrete 4. One corner on one side of a single square timber 1 is provided with an installation notch that penetrates horizontally along the transverse direction of the square timber 1 with a certain depth, and the opening of the installation notch faces upward. The width of the installation notches on each square timber 1 is the same as the thickness of the upper bin formwork 3 to be installed, and the depth of the installation notches on each square timber 1 is the same, and the depth of the installation notch can be adjusted according to the size change of the upper bin formwork 3 to be installed. In this embodiment, the square timber 1 is of a cuboid structure and is horizontally arranged transversely. One corner on the side of the cuboid structure close to the side wall of the lower layer of concrete 4 is provided with an installation notch that penetrates along the length direction of the cuboid structure and has an upward opening. One side of the installation notch of the square timber 1 is closely attached to the side surface of the lower layer of concrete 4, forming an empty groove with the side surface of the lower layer of concrete 4. The opening of the empty groove is horizontally upward. The empty groove is used to support the upper bin formwork 3 to be installed above, hold the upper bin formwork 3 from the bottom, and ensure that the upper bin formwork 3 will not slip downward. In this embodiment, the structures and sizes of each square timber 1 are the same, and the structures and sizes of the installation notches opened thereon are the same. The cross-section of the installation notch opened on the square timber 1 is L-shaped, and the cross-section of the empty groove formed by the L-shaped installation notch and the side surface of the lower layer of concrete 4 is U-shaped. The width of the empty groove formed by the installation notch of each square timber 1 and the side surface of the lower layer of concrete 4 is the same as the thickness of the upper bin formwork 3, so that the upper bin formwork 3 can be clamped into it. A through hole directly matching the tie rod 2 is provided in the middle of the square timber 1 and below the installation notch of the square timber 1. The positions and structural sizes of the through holes opened on each square timber 1 are the same. The tie rod 2 is arranged on the lower layer of concrete 4. Multiple tie rods 2 are arranged along the same horizontal line on the side surface of the lower layer of concrete 4. The top row of existing tie rods on the lower layer of concrete 4 is used, and no new ones need to be set. The tie rod 2 passes through the through hole in the middle of the square timber 1 and the washer, and the square timber 1 is fixed on the side wall of the lower layer of concrete 4 through a nut. The upper bin formwork 3 is of a rectangular plate-like structure. The upper bin formwork 3 is vertically inserted downward into the empty grooves formed by the installation notches of multiple square timbers 1 and the side surface of the lower layer of concrete 4 and clamped tightly, so that the upper bin formwork 3 is closely attached to the side surface of the lower layer of concrete 4.

[0023] During operation, when the formwork of the lower bin is removed, the top row of tie rods 2 is retained; then a hole is drilled in the middle of the square timber 1 and an installation notch is opened at one corner. The existing tie rod 2 is used to firmly fix the square timber 1 on the side wall of the lower layer of concrete 4. The opening of the installation notch on the square timber 1 faces upward and is closely attached to the side wall of the lower layer of concrete 4, forming an empty groove with an upward horizontal opening with the side wall of the lower layer of concrete 4.
