Description

Technical Field

[0001] This utility model relates to a steel-wood composite building formwork, which adopts a modular, building block design. The new steel-wood composite building formwork comes in various sizes and can be assembled into a variety of shapes, greatly facilitating construction. Background Technology

[0002] Construction formwork is used to assemble the cavities of beams, slabs, columns, and shear walls during concrete pouring in building construction. Formwork includes timber, steel, aluminum, and plastic forms, among others. Some of these forms cannot be reused, resulting in material waste; others are complex to manufacture, have limited reusability, leading to significant material waste, high operating costs, and inconvenient connections.

[0003] There is also a steel-wood composite building formwork in Chinese patent 200920011983.3. It consists of a rectangular metal frame composed of four metal frame members connected in pairs at both ends. Inside the metal frame is a connecting frame. The top of the metal frame has a panel of wood or plywood. Long, narrow holes are evenly distributed around the four sides of the metal frame, with the length of the holes perpendicular to the panel. The frame members are straight steel strips with arc-shaped grooves along their length. The bottom of the arc-shaped grooves is inside the frame, and the upper and lower edges of the arc-shaped grooves are on the same plane. At the lower groove edge of the long, narrow holes, there is a rectangular groove along the length of the long, narrow hole. At the upper groove edge of alternating long, narrow holes, there is a rectangular groove along the length of the long, narrow hole. This steel-wood composite building formwork makes on-site construction cumbersome, time-consuming, and increases the difficulty of the process. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned shortcomings by eliminating some grooves, elongated holes, and steel plate pins during manufacturing. It proposes a steel-wood composite building formwork with a simple frame construction, convenient use, and low manufacturing cost.

[0005] This utility model is implemented using the following method.

[0006] This new type of steel-wood composite building formwork uses large L-shaped steel bars made of cold-rolled thin steel sheets for its four-sided frame, and smaller L-shaped steel bars made of the same cold-rolled thin steel sheets. These two L-shaped steel bars are welded together using automatic pressure welding to form a special steel profile, which is then used to create the frame of the steel-wood composite building formwork. This profile is further welded to multiple internal square tubes to form a metal rectangular formwork frame. The upper surface of the smaller L-shaped steel bars and the upper surfaces of the multiple square tubes form a unified plane to support the wooden formwork. The upper inner side of the larger L-shaped steel bars protects the perimeter of the multi-layered wooden formwork, allowing for multiple uses of the formwork during construction. The lower surface of the larger L-shaped steel bars and the lower surfaces of the multiple square tubes form a unified plane, saving on the need for auxiliary scaffolding during construction. This new type of steel-wood composite building formwork is designed with modularity, with various shapes and sizes, allowing for the assembly of any configuration to solve construction problems. Standardization can also be achieved during production and use.

[0007] In use, this utility model of steel-wood combined building formwork can be used for beams, slabs, columns, and shear walls. When supporting floor slabs, after the main scaffolding is laid, the formwork can be freely placed along with the main scaffolding without any steel pin connections. When supporting beams, columns, and shear walls, there are dedicated scaffolding units connecting the steel-wood combined formwork, which can be placed along with the dedicated scaffolding units. No steel pin connections are needed; simply use the dedicated scaffolding units to fix the steel-wood combined building formwork connected to both sides on the same plane. On-site construction and installation of the steel-wood combined formwork is simple and convenient, saving manpower and increasing efficiency.

[0008] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0016] The present invention will be further described below with reference to the embodiments.

[0017] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention all fall within the scope of protection claimed by the present invention.

[0018] Please see Figures 1-7 In order to improve the installation speed of steel-wood composite formwork for construction, this utility model provides a new type of steel-wood composite building formwork. The main frame of the formwork is made of cold-rolled thin steel plate to form (2) large L-shaped steel, and (3) small L-shaped steel to form (3) small L-shaped steel. The (2) large L-shaped steel and (3) small L-shaped steel are welded into a special steel section by automatic pressure welding, which is used to make the frame of the steel-wood composite building formwork.

[0019] The four sides are made of special steel (2) and (3) and welded with multiple square tubes (4) to form a metal rectangular template frame. The upper surface of the small L-shaped steel (3) and the upper surface of the multiple square tubes (4) form an integral plane to support the (1) building wooden template. The upper inner side of the large L-shaped steel (2) is used to protect the (1) multi-layer wooden template. This increases the reusability of the (1) building wooden template during construction, thereby increasing economic benefits and reducing material costs.

[0020] (2) The lower plane of the large L-shaped steel and the lower plane of multiple (4) square tubes form a whole, which saves a lot of auxiliary scaffolding during construction and saves a lot of labor costs.

[0021] The new type of steel-wood composite building formwork is designed with a modular, building block style. The sizes of the steel-wood composite building formwork vary, including (111) type (2400mm long, 600mm wide), (112) type (1200mm long, 600mm wide), (113) type (2400mm long, 300mm wide), (114) type (1200mm long, 300mm wide), (115) type (2400mm long, 200mm wide), and (116) type (1200mm long, 200mm wide), etc. It can be assembled into any shape during construction. This not only solves construction problems but also saves labor costs. Because of the use of the new steel-wood composite building formwork, except for a very few joints that require on-site repair, 95% of the steel-wood composite building formwork can be assembled independently.
