Quick-release supporting device for basic cup opening formwork

Abstract

The invention discloses a quick-release supporting device for a basic cup opening formwork, and belongs to the technical field of building construction. The quick-release supporting device for the basic cup opening formwork comprises a T-shaped supporting vertical rod; a movable fixing block is arranged at the rear side of the T-shaped supporting vertical rod; a supporting rod is slidably connected with the interior of a supporting sleeve; and the cylindrical end of a worm sequentially penetrates through the inner wall of a limiting cavity and the interior of the movable fixing block to extendto the outside and is coaxially connected with a lead screw. Through the cooperation of the lead screw and worm gears, the quick-release supporting device for the basic cup opening formwork adapts todesign of different basic cup opening formwork bodies and an integrated structure is adopted, so that the dismounting and the mounting are convenient, manpower and material resources are saved, a supporting structure can be recycled, the whole structure is more stable, the formwork supporting bearing capacity of the supporting structure is guaranteed, the cup opening quality strength and the specification size of the concrete pouring cup opening foundation are guaranteed, and the situation that quality accidents are caused due to the fact that subsequent steel columns and other components arefixed in a bell and spigot joint mode is avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, and more specifically relates to a quick-release supporting device for a foundation cup formwork. Background technique [0002] The foundation cup is a type of independent foundation. When the upper structure of the building adopts a frame structure or a single-layer bent frame and gantry structure for load-bearing, the foundation often adopts a square or rectangular separate foundation, which is called an independent foundation or a column foundation. The independent foundation is the basic form of the foundation under the column. When the column adopts prefabricated components, the foundation is made into a cup shape, and then the column is inserted and embedded in the cup, so it is called the foundation cup. The pouring of the foundation cup needs formwork to be finalized. At present, industrial plant projects have a large number of foundations and a short construction period, w...

Problems solved by technology

The pouring of the foundation cup needs formwork to be finalized. At present, industrial plant projects have a large number of foundations and a short construction period, which requires high efficiency in the installation and removal of foundation formwork. However, in actual construction, the formwork and formwork support often have insufficient bearing capacity. If it is guaranteed, the formwork will cause problems such as displacement and damage, resulting in the inability to guarantee the quality, strength and specification of the cup foundation of the concrete pouring cup foundation, which will bring great uncertainty and hidden dangers to the subsequent socket fixing of steel columns and other components , causing quality accidents, consuming man-hours and material costs, the prior art publication No. CN109778900A provides a quick-release formwork structure and construction method for the foundation cup formwork, the device supports the The vertical bar and the supporting bar are made of scaffolding tubes made on site, the lug plates and iron wedges are made of steel plate cutting, the ear plates are welded at intervals on the bar, the iron wedges are welded at both ends of the supporting bar, the foundation cup mouth is positioned and set out, and the welding is completed Stirrup bracket, according to the size of the cup mouth, install the support pole inside the foundation that has been bound with steel bars. After the support pole is installed, install the support cross bar from bottom to top. The support cross bar is fixed on the corresponding The socket of the lug plate constitutes a support frame structure. During installation, the iron wedge of the support bar is on the top and the ear plate of the support vertical bar is on the bottom. However, the following problems still exist: the device is installed and connected by setting multiple pin holes and pins. The operation is cumbersome, time-consuming and labor-intensive, and it is inconvenient to disassemble and assemble the formwork after the pouring is completed, and it cannot be recycled. However, the device is all inserted through the pin shaft, which has poor stability and is prone to deformation when it receives the extrusion force of the pouring. In addition, although other existing Solution CN209144856U adopts the formwork support structure of the basic inverted trapezoidal cup mouth to save labor and remove it easily, but the height of the adjustment center adjustment mechanism in the assembly process makes the formwork reach the corresponding trapezoidal cup mouth size, and other equipment at a high place is needed Looking down to dynamically monitor the above-mentioned adjustment process, so other external equipment is also needed. In view of this, we propose a quick-release support device for the basic cup formwork
