Description

Technical Field

[0001] This utility model relates to the field of building application technology, specifically a support formwork device for building construction. Background Technology

[0002] Construction formwork is a temporary support structure mainly used in concrete pouring construction. Existing construction formwork is generally divided into wooden formwork, steel formwork, and composite material formwork. The function of construction formwork is to pour concrete into shape and size as required by the design. For example, in the construction of columns or walls, construction formwork needs to be wrapped around the shape of the column or wall. Then, concrete is poured in the space enclosed by the construction formwork. After the concrete solidifies, the construction formwork is removed to form the column or wall. Then, the column or wall can be further constructed according to the work requirements.

[0003] Construction formwork cannot be a single piece; instead, it is divided into multiple units according to the construction design requirements. These units are then spliced ​​together during use, and the splicing between the formwork units must be tight to prevent leakage of concrete slurry during the pouring process.

[0004] Existing technologies typically use methods such as steel wire fixing to secure the splicing of formwork units, but this often results in unstable fixing leading to concrete leakage.

[0005] The splicing of formwork units is quite difficult and generally requires experienced workers to carry out the construction. Otherwise, poor installation quality can easily lead to formwork collapse or unstable fixing, resulting in concrete leakage. Therefore, the splicing of formwork units often affects construction efficiency, especially the fixing of tie bolts.

[0006] Tie bolt fixing is an important fixing method in building formwork splicing. Tie bolts generally fix two opposing formwork units by pulling them together. Tie bolts are usually placed at the edge of the formwork unit, resulting in a small contact area between the connector on the tie bolt and the formwork unit. This makes it easy for the tie bolts to tilt or fall off during fixing. The construction requirements for tie bolts are relatively high. If the tie bolts are fixed too loosely, it will affect the overall structure of the building formwork and may also cause concrete leakage. If the tie bolts are fixed too tightly, they will compress the formwork unit and affect the quality of the building after pouring. Utility Model Content

[0007] The purpose of this utility model is to provide a support formwork device for building construction, which is easy to assemble, requires less skill from formwork assemblies, effectively improves the efficiency of formwork assembly, and ensures the stability of the structure after assembly, thus guaranteeing the quality of the poured building.

[0008] To achieve the above-mentioned technical effects, this utility model provides a support formwork device for building construction, comprising formwork units. Each formwork unit includes a panel and a reinforcing frame. The panel is a rectangular plate, and the reinforcing frame is a rectangular frame composed of four side strips. The reinforcing frame is fixedly connected to the rear side of the panel. The front side of the panel away from the reinforcing frame is the side that contacts the concrete. The side strips of the reinforcing frames of two adjacent formwork units are fixedly connected to each other. A through hole is provided in the center of the panel, penetrating the panel. The panels of two opposing formwork units are parallel to each other, and the through holes of the panels of two opposing formwork units are coaxial. A tie rod is inserted into the through hole of two opposing formwork units. The two ends of the tie rod extend out of the two panels respectively, and nuts II are connected to the two ends of the tie rod extending out of the two panels. An inner reinforcing seat is connected between the panels of two opposing formwork units. The inner reinforcing seat includes an inner tube, which is sleeved on the tie rod. The inner tube is located between the panels of two formwork units, and its two ends are respectively abutted against the two panels. The inner diameter of the inner tube is larger than the inner diameter of the through hole.

[0009] Furthermore, the inner reinforcement base includes an outer tube, a support plate, and a reinforcement column. The outer tube is located outside the inner tube and is coaxial with the inner tube. The support plate is fixedly connected between the outer tube and the inner tube. There are multiple support plates, which are evenly distributed around the axis of the inner tube. Each support plate is fixedly connected to a reinforcement column. The support plate has holes for the reinforcement column to pass through, and the two ends of the reinforcement column are respectively abutted against two panels.

[0010] Furthermore, each of the four side strips of the reinforcing frame is provided with a connecting hole. The two connecting holes of the reinforcing frames of two adjacent template units are coaxial, and a side pull rod is inserted into both connecting holes. The two ends of the side pull rod extend out of the two side strips of the reinforcing frame, and a nut I is connected to both ends of the side pull rod extending out of the two side strips of the reinforcing frame.

[0011] Furthermore, each side strip of the reinforcing frame has multiple connecting holes, which are evenly distributed along the length of the side strip of the reinforcing frame, and a side pull screw is inserted into each connecting hole.

[0012] Furthermore, each nut II is connected to the panel with an external reinforcement seat, which is sleeved on the tie rod. The external reinforcement seat includes a large ring, a small ring, and a support rod. The large ring and the small ring are coaxial, with the large ring positioned above the small ring. The support rod is fixedly connected between the large ring and the small ring and is inclined. There are multiple support rods, which are evenly distributed around the axis of the large ring. The surface of the large ring facing away from the support rod is attached to the panel, and the surface of the small ring facing away from the support rod is attached to the nut II.

[0013] Furthermore, the support rod is made of ABS.

[0014] Furthermore, each template unit includes four stiffening plates, which are respectively located at the four corners of the rectangular reinforcing frame, and each stiffening plate connects to two side strips of the reinforcing frame.

[0015] Furthermore, the stiffening plate is triangular.

[0016] Furthermore, the support plate is fan-shaped.

[0017] As one embodiment of the present invention, one of the two panels of two adjacent template units has a groove on its four-sided side wall, and the other panel of two adjacent template units has a protrusion extending from its four-sided side wall, the protrusion being inserted into the groove.

[0018] The beneficial effects of this utility model are as follows: This utility model provides support and positioning by setting the spacing between the relative template units through the internal reinforcement base, which facilitates the connection of the tie rods and moves the installation position of the tie rods from the edge of the template unit to the center, making the installation of the tie rods simpler and more convenient. This utility model has a stable structure, a firm and tight connection, and is easy to operate. It improves the work efficiency of template unit splicing, ensures the quality of template unit splicing, ensures the smooth implementation of concrete pouring, and ensures the quality of building construction.

Detailed Implementation

[0030] like Figures 1-8 As shown, Embodiment 1 of the present invention, a support formwork device for building construction, includes formwork units. Each formwork unit includes a panel 1 and a reinforcing frame 2. The panel 1 is a rectangular plate, and the reinforcing frame 2 is a rectangular frame composed of four side strips. The reinforcing frame 2 is fixedly connected to the rear side of the panel 1. The front side of the panel 1 away from the reinforcing frame 2 is the side that contacts the concrete. The side strips of the reinforcing frames 2 of two adjacent formwork units are fixedly connected to each other. A through hole 101 is provided in the center of the panel 1, and the through hole 101 penetrates the panel 1. The panels 1 of two opposite formwork units are parallel to each other, and the through holes 101 of the panels 1 of two opposite formwork units are coaxial. A tie rod 6 is inserted into the through hole 101 of two opposite formwork units. The two ends of the tie rod 6 extend out of the two panels 1 respectively, and nuts II 7 are connected to the two ends of the tie rod 6 extending out of the two panels 1. An inner reinforcement base 9 is connected between the panels 1 of the unit. The inner reinforcement base 9 includes an inner tube 901, an outer tube 902, a support plate 903, and a reinforcement column 904. The outer tube 902 is located outside the inner tube 901 and is coaxial with the inner tube 901. The support plate 903 is fixedly connected between the outer tube 902 and the inner tube 901. There are multiple support plates 903, which are evenly distributed around the axis of the inner tube 901. Each support plate 903 is fixedly connected to a reinforcement column 904. The support plate 903 has a hole for the reinforcement column 904 to pass through. The inner tube 901 is sleeved on the tie rod 6. The inner tube 901 is located between the panels 1 of the two template units. The two ends of the inner tube 901 are respectively abutted on the two panels 1. The inner diameter of the inner tube 901 is larger than the inner diameter of the through hole 101. The two ends of the reinforcement column 904 are respectively abutted on the two panels 1. The support plate 903 is fan-shaped.

[0031] This invention improves the structural strength of panel 1 by setting up the reinforcing frame 2. In addition, since the thickness of panel 1 is limited, this invention increases the thickness of template unit by setting up the reinforcing frame 2. The template unit can be spliced ​​by fixing the edge strips of the reinforcing frame 2 of two adjacent template units together. It should be noted that when splicing multiple template units, in addition to fixing the edge strips of the two reinforcing frames 2 together, it is also necessary to ensure that the top of adjacent panels 1 are tightly joined. This invention moves the tie rod assembly, which is mostly located at the edge of the template unit in the prior art, to the center of the panel 1. In this invention, the tie rod 6 is connected by a through hole 101. At the same time, an inner reinforcement seat 9 is added. The inner reinforcement seat 9 provides support for the two opposing panels 1 and positions them at a distance. When tightening the nut II7 on the tie rod 6, the inner tube 901 and the reinforcing column 904 fix the distance between the two opposing panels 1. Tightening the nut II7 will not cause the distance between the two panels 1 to decrease, thus preventing the change in the distance between the panels 1 due to over-tightening of the nut II7. This ensures the quality of subsequent concrete pouring. The inner tube 901 is sleeved on the outside of the tie rod 6 to prevent the inner reinforcement seat 9 from being misaligned and to prevent concrete from entering the inner tube 901 and contacting the tie rod 6 during pouring. After the concrete solidifies, the tie rod 6 can be removed by loosening the nut II7, while the inner reinforcement seat 9 remains inside the building structure.

[0032] In this first embodiment, there are eight support plates 903 and eight reinforcing columns 904.

[0033] Each of the four side strips of the reinforcing frame 2 is provided with a connecting hole 201. The two connecting holes 201 of the reinforcing frame 2 of two adjacent template units are coaxial. A side tie rod 4 is inserted into the two connecting holes 201. The two ends of the side tie rod 4 extend out of the two side strips of the reinforcing frame 2 respectively. Nuts I5 are connected to the two ends of the side tie rod 4 extending out of the two side strips of the reinforcing frame 2. Each side strip of the reinforcing frame 2 has multiple connecting holes 201. The multiple connecting holes 201 are evenly distributed along the length of the side strip of the reinforcing frame 2. A side tie rod 4 is inserted into each connecting hole 201.

[0034] This utility model achieves a fixed connection between adjacent reinforcing frames 2 through the setting of side tie rods 4 and nuts I5. Since the side strips of adjacent reinforcing frames 2 are connected by mutual abutment, it is only necessary to tighten nuts I5. In this embodiment, each side strip of the reinforcing frame 2 is provided with two connecting holes 201, that is, each side strip of the reinforcing frame 2 is fixed by two side tie rods 4.

[0035] Each nut II7 is connected to the panel 1 by an external reinforcement seat 8. The external reinforcement seat 8 is sleeved on the tie rod 6. The external reinforcement seat 8 includes a large ring 801, a small ring 802 and a support rod 803. The large ring 801 and the small ring 802 are coaxial. The large ring 801 is located above the small ring 802. The support rod 803 is fixedly connected between the large ring 801 and the small ring 802. The support rod 803 is inclined. There are multiple support rods 803. The multiple support rods 803 are evenly distributed around the axis of the large ring 801. The surface of the large ring 801 facing away from the support rod 803 is connected to the panel 1. The surface of the small ring 802 facing away from the support rod 803 is connected to the nut II7. The support rod 803 is made of ABS.

[0036] The outer reinforcement seat 8 improves the fixing effect of nut II7 on panel 1. When tightening nut II7, the support rod 803 made of ABS material will prevent nut II7 from loosening.

[0037] Each template unit includes four stiffening plates 3, which are respectively located at the four corners of the rectangular reinforcing frame 2. Each stiffening plate 3 connects to two side strips of the reinforcing frame 2; the stiffening plate 3 is triangular.

[0038] The addition of stiffening plate 3 improves the structural stability of reinforced frame 2.

[0039] In this embodiment, each nut II7 and each nut I5 are used in conjunction with a washer to prevent the nut from loosening. Each nut is used with a flat washer and an elastic washer.

[0040] like Figure 9-10 As shown, the difference between Embodiment 2 and Embodiment 1 of the present invention for a support formwork device for building construction is that in this embodiment, one of the two panels 1 of two adjacent formwork units has a groove 102 on its four sides, and the other panel 1 of two adjacent formwork units has a protrusion 103 extending from its four sides, and the protrusion 103 is inserted into the groove 102.

[0041] The second embodiment of this utility model adds a connection structure between two adjacent panels 1 based on the previous embodiment. The two panels 1 are tightly connected by inserting a protrusion 103 into a groove 102, thereby preventing concrete leakage at the connection between the two panels 1.

[0042] In this utility model, since the panel 1 is rectangular, theoretically, one template unit can be connected to other template units on all four sides. Taking the form that the panel 1 of the central template unit has grooves 102 on its four sides and protrusions 103 on the side walls of the panel 1 of the surrounding template units as an example, when one template unit is connected to other template units on all four sides, it is necessary to consider that the protrusions 103 of the multiple panels 1 on all four sides should not interfere with each other. Measures that can be taken include setting the four corners of the protrusions 103 as chamfers or setting rectangular notches at the four corners of the protrusions 103. Various mechanisms can be used here, as long as they can meet the splicing of multiple template units. They will not be described in detail here.
