Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a hanging formwork bracket. Background Art

[0002] Hanging formwork refers to a formwork that is suspended in the air without a lower vertical support. The most obvious difference from other formwork construction is that there is no vertical support at the bottom or a special method is used to fix the support. Generally, it bears lateral loads and maintains its stability, which can make the horizontality and verticality of concrete components meet the requirements. Hanging formwork construction is an important construction technology in the field of building construction. The hanging formwork can be fixed in a variety of ways. The most common method is to use concrete pads or welded steel bar brackets as support at the bottom, and side steel pipes and wooden squares as back ribs or diagonal braces for fixing.

[0003] Due to the large lateral load of the hanging formwork, in the existing construction technology, temporary brackets are usually used to support and reinforce the bottom of the hanging formwork to reduce its lateral load and improve the reliability of the hanging formwork. Temporary brackets at construction sites are usually composed of steel bars, steel pipes, wooden squares, etc., which are combined to form a support frame. Due to the poor compatibility of temporary brackets with the hanging formwork, it is difficult to achieve a firm and stable characteristic. The support is prone to leakage hazards, and the plane position and height cannot be freely adjusted. In addition, temporary brackets are difficult to store and carry, and cannot be reused, so they have many disadvantages. Utility Model Content

DETAILED DESCRIPTION

[0018] The utility model provides a hanging formwork bracket to solve the technical problems in the existing construction technology that the temporary bracket and the hanging formwork are poorly compatible, the temporary bracket is difficult to store and carry, and cannot be reused.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model embodiment provides a hanging mold bracket, such as Figure 1-Figure 3 As shown, it mainly includes: a transverse support rod 1, a longitudinal support rod 2 and a movable support rod 3. Among them, a positioning pin 4 is fixed on the inner side of the first end of the transverse support rod 1; a limiting groove 5 is arranged on the outer side of the first end of the transverse support rod 1, the bottom of the limiting groove 5 is arranged horizontally, and an upwardly tilted limiting piece is arranged on the outer side of the limiting groove 5, the lower ends of the wood 14 and the template 13 are installed in the limiting groove 5, the wood 14 and the template 13 are arranged side by side in the longitudinal direction, and the wood 14 and the template 13 are limited to the inner side of the limiting groove 5 by the limiting piece; in addition, the limiting groove 5 also has the function of limiting the height of the wood 14 and the template 13.

[0021] The lower end of the longitudinal support rod 2 is provided with a first bayonet 6, which cooperates with the positioning pin 4. When the hanging mold bracket is in the working state, the positioning pin 4 is stuck in the first bayonet 6; when the hanging mold bracket is in the folded state, the positioning pin 4 is separated from the first bayonet 6. One end of the movable support rod 3 is movably connected to the transverse support rod 1, and the other part of the movable support rod 3 is movably connected to the longitudinal support rod 2. The purpose of setting the movable support rod 3 in a movable connection mode is to facilitate the folding and storage of the hanging mold bracket. The upper end of the longitudinal support rod 2 is provided with a through hole or a connector for anchoring the upper part of the hanging mold or lap anchoring the vertical rod. One side of the transverse support rod 1 is provided with a first sleeve 9 for installing a water stop screw 12. The first sleeve 9 can be welded and fixed to the transverse support rod 1 or integrated with the transverse support rod 1.

[0022] In a preferred embodiment provided by the present utility model, Figure 1 and Figure 2 As shown, the transverse support rod 1 and the longitudinal support rod 2 are both configured as C-shaped steel structures; the width of the longitudinal support rod 2 is smaller than the width of the C-shaped groove on the transverse support rod 1; when in the folded state, the longitudinal support rod 2 is stored in the C-shaped groove of the transverse support rod 1; adopting this structural design method can further reduce the volume occupied by the hanging formwork bracket in the folded state, and further improve the portability of the hanging formwork bracket.

[0023] In order to further improve the supporting stability of the formwork support, a preferred solution provided by the utility model further provides a second bayonet 7 on the longitudinal support rod 2 and a third bayonet 8 on the transverse support rod 1. The second bayonet 7 and the third bayonet 8 correspond to each other and are in an inverted triangle shape. The second bayonet 7 is used to place one end of a temporary diagonal brace 11, and the third bayonet 8 is used to place the other end of the temporary diagonal brace 11; wherein the temporary diagonal brace 11 is usually made of structural members such as wooden squares 14 or steel pipes at the construction site.

[0024] The above schemes show the embodiments of the formwork bracket used alone. At the construction site, if the support capacity of the formwork bracket needs to be improved or the formwork is large, multiple formwork brackets can be connected to form an integral formwork bracket unit. In order to achieve the connection of multiple formwork brackets, a second sleeve 10 can be set on the other side of the transverse support rod 1 of a single formwork bracket. The second sleeve 10 is connected to the second sleeve 10 of the adjacent formwork bracket through a connecting piece. The connecting piece can be a scissor bracket, which has strong stability and load-bearing capacity.

[0025] like Figure 1-Figure 3 As shown, the working process of the formwork hanging bracket provided by the embodiment of the utility model is as follows: when using the formwork hanging bracket, the longitudinal support rod 2 and the transverse support rod 1 are unfolded to form a 90° angle, and the positioning pin 4 is inserted into the first bayonet 6, so that the longitudinal support rod 2, the transverse support rod 1 and the movable support rod 3 form a stable triangular structure, and the transverse screw rod is supported by the water stop screw rod 12. The lower ends of the wood 14 and the template 13 are installed in the limiting groove 5, and the wood 14 and the template 13 are supported by the formwork hanging bracket. After the construction is completed, the wood 14 and the template 13 are removed, the first bayonet 6 is separated from the positioning pin 4, and the transverse support rod 1 and the longitudinal support rod 2 are folded.
