Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a formwork device for building construction that is easy to adjust. Background Technology

[0002] In building construction, the pouring of openings in the building, such as reserved openings for doors and windows and reserved holes for equipment installation, is a key step. During construction, a pouring cavity that matches the opening of the building needs to be constructed using formwork. After the two ends of the formwork are fixed to the building, a steel cage is placed in and concrete is poured to complete the integrated construction of the wall.

[0003] The current traditional formwork fixing process has obvious defects. After the formwork is installed, in order to prevent displacement, deformation or leakage due to lateral pressure and self-weight pressure during concrete pouring, additional reinforcement is required: first, steel pipes are fixed one by one on the outside of both ends of the formwork and fastened to the formwork frame with buckles and bolts; then, steel wire ropes are used to connect the steel pipes at both ends laterally, and the tension is adjusted by turnbuckles to form a limiting support.

[0004] The core problem with this method lies in its cumbersome operation and poor adjustability. On the one hand, fixing the steel pipes requires manual calibration of each pipe, and laying the wire ropes requires multiple people working together, which is time-consuming and labor-intensive, and poses higher safety risks when working at heights or with large openings. On the other hand, the tension of the wire ropes depends on manual experience; too tight a rope can easily cause the formwork to deform, while too loose a rope can cause the limiting mechanism to fail, leading to deviations in wall dimensions and increasing the cost of secondary repairs. In addition, the reinforcement components are cumbersome to disassemble and are susceptible to concrete contamination and corrosion, resulting in low reusability. Based on this, an easily adjustable formwork fixing device was designed, which can quickly limit the formwork during pouring to prevent displacement at both ends, and is also easy to disassemble and reuse. Utility Model Content

[0005] In view of the shortcomings of the above-mentioned traditional methods, the purpose of this utility model is to provide an easily adjustable formwork device for building construction, which can quickly limit the formwork during pouring to prevent displacement at both ends, and is easy to disassemble and can be reused.

[0006] The technical implementation scheme of this utility model is as follows:

[0007] An adjustable formwork device for building construction includes a first square steel, a first screw, a gearbox, a first formwork mechanism, and a second formwork mechanism. The first square steel has a first screw inside, which is connected to the gearbox. The two sides of the gearbox are respectively connected to the first formwork mechanism and the second formwork mechanism. The first formwork mechanism includes a second square steel, a first locking plate, and a second screw. The first locking plate is connected to the sliding groove on the second square steel and the second screw through a slider and a screw hole at its upper part. One end of the first screw, which passes through the first square steel, is connected to a rotating handle.

[0008] Optionally, the first screw is movably connected to the inner cavity of the first square steel via a bearing.

[0009] Optionally, the gearbox is internally provided with a turbine and a worm, the worm being mounted on a first screw and the turbine being mounted on a second screw, and the turbine and worm being meshed to form a transmission structure.

[0011] Optionally, the first locking plate is provided with a connecting hole, and the connecting screw passes through the connecting hole and connects to the second locking plate on the second template mechanism. The connecting screw is fixed at the connection point by a nut.

[0012] Optionally, one end of the second square steel is connected to the gearbox opening by screws, and bearings are provided at both the gearbox and the port of the second square steel.

[0013] Optionally, the upper part of the first square steel is provided with a lifting handle, and the lifting handle is provided with a flexible rubber layer; the second square steel is provided with a scale strip.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] like Figures 1-5 As shown, an adjustable template device for building construction includes a first square steel 1, a first screw 8, a gearbox 2, a first template mechanism 3, and a second template mechanism 4. The first square steel 1 has a first screw 8 inside, and the first screw 8 is connected to the gearbox 2. The two sides of the gearbox 2 are respectively connected to the first template mechanism 3 and the second template mechanism 4. The first template mechanism 3 includes a second square steel 301, a first locking plate 302, and a second screw 306. The first locking plate 302 is connected to the sliding groove 303 on the second square steel 301 and the second screw 306 through the upper slider 304 and screw hole 307, respectively. One end of the first screw 8 that passes through the first square steel 1 is connected to a rotating handle 9.

[0025] It should be noted that the first square steel 1 is a rectangular cavity structure with openings at both ends, and a first screw 8 is installed inside the first square steel 1 to drive the rotation of the gearbox 2 and transmit power to the first template mechanism 3 and the second template mechanism 4. The second square steel 301 is a rectangular cavity structure with an opening at the bottom, and a second screw 306 is installed inside the second square steel 301. The first locking plate 302 is connected to the sliding groove 303 on the second square steel 301 and the second screw 306 through the upper slider 304 and screw hole 307, respectively. It moves under the rotation of the second screw 306. The two symmetrical locking plates achieve pre-tightening and locking of the two sides of the construction template, so that during construction and pouring, displacement of both sides occurs due to its own weight and the squeezing force generated when pouring concrete.

[0026] like Figures 1-5As shown, the first screw 8 is movably connected to the inner cavity of the first square steel 1 via a bearing; the gearbox 2 is provided with a turbine 11 and a worm gear 10 inside, the worm gear 10 is provided on the first screw 8, the turbine 11 is provided on the second screw 306, and the turbine 11 and the worm gear 10 are meshed to form a transmission structure.

[0027] It should be noted that the gearbox 2 has open ends for connecting the second square steel 301 and the third square steel. The worm gear 10 inside is located on the first screw 8, and the turbine gear 11 is located on the second screw 306. The two are meshed and connected. By rotating the first screw 8, the torque generated can be transmitted to the turbine gear 11 through the worm gear 10, causing the turbine gear 11 to rotate, which in turn drives the second screw 306 to rotate.

[0028] like Figures 1-4 As shown, the upper part of the first locking plate 302 is provided with several reinforcing ribs, and the part of the first locking plate 302 near the construction template 5 is provided with an extrusion layer.

[0029] It should be noted that the upper reinforcing rib of the first locking plate 302 is designed to improve the overall strength of the locking plate, while the extrusion layer is generally made of a rubber layer with low flexibility, the purpose of which is to ensure close contact with the construction template 5 during the pressure application process.

[0030] like Figures 1-4 As shown, the first locking plate 302 is provided with a connecting hole 308, and the connecting screw 7 passes through the connecting hole 308 and connects to the second locking plate on the second template mechanism 4. The connecting screw 7 is fixed by a nut 6 at the connection point.

[0031] It should be noted that the first locking plate 302 is connected to the second locking plate via the connecting screw 7. The purpose of this design is to fix the first locking plate 302 and the second locking plate again via the connecting screw 7 after the first locking plate 302 and the second locking plate have been fixed and limited, thereby improving the stability of the entire structure.

[0032] It should be further explained that during operation, the entire first template mechanism 3 and the second template mechanism 4 are fitted onto the construction template 5. The construction template 5 is fixed on both sides by rotating the first screw 8 to achieve the limit. After fixing, the connecting screw 7 is installed and fixed to the locking plate by the nut 6 to achieve the second limit.

[0033] like Figures 1-5 As shown, one end of the second square steel 301 is connected to the opening of the gearbox 2 by a screw 305, and bearings are provided at both the gearbox 2 and the port of the second square steel 301; a lifting handle is provided on the upper part of the first square steel 1, and a flexible rubber layer is provided on the lifting handle; a scale strip is provided on the second square steel 301.

[0034] It should be noted that the lifting handle facilitates the movement of the entire device, while the scale bar allows for observation of the locking plate's movement distance, making it convenient to adjust as needed during construction.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
