Description

Technical Field

[0001] The utility model relates to the technical field of formwork application, in particular to an integrated large formwork device without internal tie rods for rapid formwork support. Background Art

[0002] In the construction of building concrete projects, wall cast-in-place large formworks usually need to be equipped with tie rods to balance the lateral pressure of concrete. However, when the lateral pressure of concrete is large, it is often necessary to increase the number of tie rods and reduce their spacing to meet the design requirements of formwork strength and stiffness.

[0003] This situation will lead to an increase in the collision points between the tie rods and the wall reinforcement, thus increasing the construction difficulty and having an adverse impact on the pouring quality of concrete. In addition, when the project requires the concrete to have waterproof performance or achieve the effect of fair-faced concrete, the holes left after removing the tie rods will affect the realization of these goals and increase the later treatment cost. The installation and removal of tie rods require sufficient operating space. If the construction space is insufficient, the installation and removal cannot be carried out smoothly. In addition, the process of installing and removing tie rods is time-consuming and laborious, increasing the labor and time costs. In the case of large lateral pressure of concrete, high requirements for pouring quality, limited construction space and high requirements for turnover efficiency, the traditional internal tie rod formwork components are not applicable enough.

[0004] Therefore, in view of the above problems, we propose an integrated large formwork component without internal tie rods for rapid formwork support to meet the needs of building construction. Content of the Utility Model

[0006] To achieve the above purpose, an integrated large formwork device without internal tie rods for rapid formwork support adopted by the utility model includes an integrated rapid formwork support mechanism.

The top tie-in assembly 3 includes a top tie-in 31 and a top pressing beam 32. By the foregoing solution, the process of installing and removing tie rods is time-consuming and laborious, increasing the labor and time costs. In the case of large concrete side pressure, high pouring quality requirements, limited construction space, and high turnover efficiency requirements, the traditional internal tie rod formwork assembly 1 is not applicable enough. It can be understood that the wooden formwork 11 and the steel truss 12 in the foregoing solution are connected by horizontal back ribs. The embedded part group 21 is pre-embedded according to the design requirements. The bottom position of the formwork is fixed by the bottom anchoring assembly 2, the top of the formwork is fixed by the top tie-in system, and the inclined support 4 is connected to ensure the overall stability of the formwork assembly 1. The steel truss 12 in the large formwork assembly 1 uses lightweight and high-strength materials, which not only ensures safety but also effectively solves the problem of insufficient construction operation space. The formwork main body does not need to install and remove tie bolts, and can meet the engineering requirements of waterproof requirements or the pursuit of fair-faced concrete effect. The steel truss 12 and the large formwork have a high overall integration degree. After assembly, the overall installation and removal and turnover use can be realized, which is very convenient. The embedded part group 21 and the frame body are designed in a separated manner, which can flexibly avoid the bottom slab steel bars or other obstacles that hinder the embedding of the embedded parts. The construction is convenient and does not affect the overall anchoring force of the anchoring assembly.

[0021] For this specific embodiment, the bottom anchoring assembly 2 is detachably connected to the formwork assembly 1 and is located below the formwork assembly 1. The top tie-in assembly 3 is detachably connected to the formwork assembly 1 and is located above the formwork assembly 1. The inclined support 4 is detachably connected to the formwork assembly 1 and is located on one side of the formwork assembly 1. The inclined support 4 is connected to the horizontal back rib to form a triangular stable structure with the formwork assembly 1.

[0022] Among them, the steel truss 12 is detachably connected to the inclined support 4 and is located on one side of the inclined support 4. Moreover, the steel truss 12 is arranged between the top tie assembly 3 and the bottom anchorage assembly 2. The wooden formwork 11 is detachably connected to the steel truss 12 and is located on the side of the steel truss 12 away from the inclined support 4. The wooden formwork 11 and the steel truss 12 are connected by horizontal backing ribs to form the formwork assembly 1.

The C-shaped steel stiffening rib 122 is detachably connected to the vertical double C-shaped steel 121 and is located on the side of the vertical double C-shaped steel 121 away from the inclined support 4. The rectangular tube stiffening rib 123 is detachably connected to the vertical double C-shaped steel 121 and is located above the vertical double C-shaped steel 121. The double angle steel stiffening rib 124 and the lifting hook 125 are fixedly connected to the C-shaped steel stiffening rib 122 and are located on one side of the C-shaped steel stiffening rib 122. And the C-shaped steel stiffening rib 122 is vertically arranged with the vertical double C-shaped steel 121. The lifting hook 125 is detachably connected to the top tie assembly 3 and is located below the top tie assembly 3. The lifting hook 125 is arranged on the vertical double C-shaped steel 121, and the lifting hook 125 is arranged on one side of the rectangular tube stiffening rib 123.

[0024] Meanwhile, the bottom anchorage support 22 is detachably connected to the vertical double C-shaped steel 121 and is located below the vertical double C-shaped steel 121. The embedded part group 21 is detachably connected to the bottom anchorage support 22 and is located below the bottom anchorage support 22. The bottom tie member 23 is detachably connected to the bottom anchorage support 22 and is located on one side of the bottom anchorage support 22. And the bottom tie member 23 is vertically arranged with the embedded part group 21. The bottom pressing beam 24 is arranged on the outer surface of the bottom tie member 23. The embedded part group 21 needs to be buried in advance according to the design requirements. After the formwork is supported, the bottom anchorage support 22 and the bottom pressing beam 24 are installed. The bottom of the formwork is fixed through the bottom tie member 23. The lateral pressure of the concrete on the lower part of the formwork is borne by the bottom anchorage assembly 2.

[0025] In addition, the top pressing beam 32 is detachably connected to the lifting hook 125 and is located above the lifting hook 125. The top tie member 31 is fixedly connected to the top pressing beam 32 and is located on one side of the top pressing beam 32.

After the formwork is set up, the top pressing beam 32 is installed, and then the formwork is fixed through the top tie member 31. Since the tie member is connected and fixed to the top pressing beam 32, the position adjustment of the tie member is convenient, and the upper side pressure of the concrete is borne by the top tie assembly 3.

[0026] When the present utility model is in use, the wooden formwork 11 and the steel truss 12 are connected through horizontal backing ribs. The embedded part group 21 is pre-embedded according to the design requirements. The bottom position of the formwork is fixed through the bottom anchoring assembly 2, and the top of the formwork is fixed through the top tie system. The connecting diagonal brace 4 ensures the overall stability of the formwork assembly 1. The steel truss 12 in the large formwork assembly 1 adopts a lightweight and high-strength material, which not only ensures safety but also effectively solves the problem of insufficient construction operation space. The formwork main body does not need to install and remove the tension bolts, which can meet the engineering requirements of waterproof requirements or the pursuit of fair-faced concrete effect. The integration degree of the steel truss 12 and the large formwork is high. After assembly, the whole can be installed and removed for turnover use, which is very convenient. The embedded part group 21 and the frame body are designed in a separated manner, which can flexibly avoid the bottom plate steel bars or other obstacles that prevent the embedding of the embedded parts. The construction is convenient and does not affect the overall anchoring force of the anchoring assembly.
