The utility model discloses a formwork structure for a construction joint of a bottom plate outer wall. The formwork structure comprises a brick forming die; the outer side template is positioned on the brick moulding bed; the inner side formworks are arranged on the inner sides of the outer side formworks at intervals, and the bottoms of the inner side formworks are supported through supporting split heads. The concrete cushion layer is laid on the foundation, and the concrete cushion layer is located on the brick moulding bed; and the supporting split heads are positioned on the concrete cushion layer at the forming space of the concrete bottom plate. When the outer side formwork body and the inner side formwork body are connected through the through bolts, the bottom of the inner side formwork body is supported through the supporting split heads, an operator only needs to hold the inner side formwork body without lifting the inner side formwork body, and the problem that the bottom of the inner side formwork body is in an unsupported suspended state is solved; and during installation, an operator needs to lift the inner side formwork to be installed with the outer side formwork, so that the formwork erecting labor intensity is increased.

Description

Technical Field

[0001] The utility model relates to a bottom plate external wall construction joint formwork structure, belonging to the technical field of construction joint formwork. Background Art

[0002] When the construction joint of the base plate and the exterior wall is cast, the bottom of the inner formwork in the prior art is in an unsupported suspended state (see Chinese Patent Publication No. CN117211343A). When pouring concrete in the later stage, the workers need to lift the inner formwork to install it with the outer formwork, which increases the labor intensity of the formwork. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a formwork structure for a base plate exterior wall construction joint.

[0004] The utility model is realized through the following technical solutions.

[0005] The utility model provides a bottom plate exterior wall construction joint formwork structure, comprising:

[0006] Brick mold;

[0007] The outer template on the brick mold;

[0008] The inner formwork is spaced inside the outer formwork, and the bottom of the inner formwork is supported by a supporting saddle.

[0009] It also includes a concrete cushion layer laid on the foundation, which is located on the brick formwork; the supporting horse stool is located on the concrete cushion layer at the concrete bottom plate forming space.

[0010] The outer side of the outer template and the inner template are both provided with back corrugated plates, and the outer side of the back corrugated plates are provided with steel pipes; the outer template and the inner template are connected through through bolts, and the nuts screwed on the through bolts are pressed on the steel pipes on the outer side of the outer template and the inner template.

[0011] Concrete tongue-and-groove wood blocks are pre-embedded on the inner surfaces of the tops of the outer and inner formworks.

[0012] There is a concrete bottom plate in the interval between the outer formwork and the inner formwork; the supporting horse stool is wrapped in the concrete bottom plate.

[0013] It also includes a water-stop steel plate whose upper section is located in the later-cast exterior wall; the lower section of the water-stop steel plate is located in the concrete bottom plate.

[0014] The beneficial effects of the present utility model are as follows: When the outer formwork and the inner formwork are connected by through bolts, the bottom of the inner formwork is supported by supporting stools. Workers only need to hold the inner formwork instead of lifting it, solving the problem that the bottom of the inner formwork is in a suspended state without support and workers need to lift the inner formwork during installation to install it with the outer formwork, which increases the labor intensity of formwork support. Brief Description of the Drawings

[0015] Figure 1 is a sectional schematic view of the present utility model;

[0016] In the figure: 1 - Foundation base; 2 - Concrete cushion; 3 - Brick tire formwork; 4 - Outer formwork; 5 - Inner formwork; 6 - Supporting stool; 7 - Steel pipe; 8 - Through bolt; 9 - Concrete keyway wooden square; 10 - Concrete floor slab; 11 - Backing plate; 12 - Waterstop steel plate. Detailed Embodiment

[0017] The technical solution of the present utility model will be further described below, but the scope of protection claimed is not limited thereto.

[0018] As Figure 1 shown.

[0019] A formwork support structure for the construction joint of the bottom slab and exterior wall of the present application includes:

[0020] A concrete cushion 2 laid on the foundation base 1, with a brick tire formwork 3 on the concrete cushion 2, and an outer formwork 4 installed on the brick tire formwork 3; an inner formwork 5 is spaced inside the outer formwork 4, and the bottom of the inner formwork 5 is supported by a supporting stool 6 composed of steel bars.

[0021] Both the outer formwork 4 and the inner formwork 5 are provided with backing plates 11 on the outside, and there are steel pipes 7 outside the backing plates 11; the outer formwork 4 and the inner formwork 5 are connected through the through bolts 8 in a through manner, and the nuts screwed on the through bolts 8 are pressed on the steel pipes 7 outside the outer formwork 4 and the inner formwork 5.

[0022] Concrete keyway wooden squares 9 are embedded in the inner surfaces at the tops of the outer formwork 4 and the inner formwork 5, and the concrete keyway wooden squares 9 are removed after the concrete floor slab 10 is fixed and formed to form a concrete keyway for identifying the connection part of the later outer wall.

[0023] When the outer formwork 4 and the inner formwork 5 are connected by the through bolts 8, the bottom of the inner formwork 5 is supported by the supporting stools 6. The operator only needs to hold the inner formwork 5 instead of lifting it, solving the problem that the bottom of the inner formwork is in a suspended state without support and the operator needs to lift the inner formwork during installation to install it with the outer formwork, which increases the labor intensity of formwork support. When the concrete is poured and solidified in the interval between the outer formwork 4 and the inner formwork 5 after erection to form the concrete floor slab 10, the supporting stools 6 are then wrapped inside the concrete floor slab 10.

[0024] A water stop steel plate 12 is embedded vertically in the concrete floor slab 10. The lower half of the water stop steel plate 12 is inside the concrete floor slab 10, and the upper half of the water stop steel plate 12 is in the exterior wall to be cast later. The water stop steel plate 12 serves as a water stop.
