Description

Technical Field

[0001] The utility model belongs to the technical field of building formwork supports, and particularly relates to a beam bottom formwork double-steel pipe main rib laying connection structure and a beam bottom formwork support structure thereof. Background Technique

[0002] In traditional concrete formwork support construction, when a single steel pipe is used as the main rib at the beam bottom, the single steel pipe at the beam bottom and the vertical poles on both sides of the beam can be connected by conventional right-angle fasteners, but the bearing capacity needs to be improved by reducing the longitudinal spacing of the vertical poles at the beam bottom.

[0003] When double steel pipes are used as the main rib at the beam bottom, there are usually two forms to solve the problem of collision between the double steel pipes and the vertical poles on both sides of the beam:

[0004] The first form is to use two steel pipes with different lengths at the beam bottom, and connect the longer steel pipe with the vertical poles on both sides of the beam by fasteners; the second form is to adopt "the vertical poles of the beam and slab are not shared".

[0005] In the first form, although double steel pipes are used at the beam bottom, only a single steel pipe is connected to the vertical poles on both sides of the beam, which fails to achieve the stable effect of double steel pipes and increases potential safety hazards; in the second form, "the vertical poles of the beam and slab are not shared" increases the additional vertical poles at the beam bottom, which not only increases the workload, reduces the construction efficiency, but also reduces the stability of the top of the formwork support. Content of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a beam bottom formwork double-steel pipe main rib laying connection structure and a beam bottom formwork support structure thereof.

[0007] To achieve the above purpose, the utility model is implemented by the following technical solutions:

[0008] In the first aspect, the utility model provides a beam bottom formwork double-steel pipe main rib laying connection structure, including:

[0009] Beam side vertical poles, arranged on the transverse sides of the beam bottom formwork;

[0010] Beam bottom vertical poles, arranged directly below the beam bottom formwork and equipped with a U-shaped top support that can be telescoped up and down at the top;

[0013] Furthermore, the double-pipe side support components adopt vertical pole side support right-angle fasteners or three-steel pipe right-angle fasteners.

[0014] Furthermore, the vertical rod side support right-angle fastener includes a first fastener part and right-angle side supports symmetrically arranged on both sides of the top of the first fastener part. The first fastener part is buckled on the side vertical rod of the beam, and the two right-angle side supports are relatively in a U-shaped trough in the buckled state of the first fastener part, respectively used to support one steel pipe main rib of the double-steel pipe main rib.

[0015] Furthermore, the three-steel-pipe right-angle fastener includes a first fastener part in the middle, and a second fastener part and a third fastener part symmetrically located on both sides of the first fastener part and connected at a right angle. The first fastener part is buckled on the side vertical rod of the beam, and the second fastener part and the third fastener part are buckled on one steel pipe main rib connecting the double-steel pipe main rib.

[0016] Furthermore, the first fastener part, the second fastener part, and the third fastener part respectively include two matching buckled hoops and bolts for connecting the hoops.

[0017] Furthermore, a cross bar, a scissors brace or a diagonal tie rod are respectively fixedly connected between the side vertical rod of the beam and the bottom vertical rod of the beam in the horizontal and vertical directions.

[0018] In a second aspect, the present utility model provides a beam bottom formwork support structure, including:

[0019] The floor bottom formwork,

[0020] The beam bottom formwork, which is in a groove shape downward from the floor bottom formwork,

[0021] And the beam bottom formwork double-steel pipe main rib resting connection structure as described in any one of the first aspect;

[0023] Compared with the prior art, the beneficial effects achieved by the present utility model:

[0024] The beam bottom formwork double-steel pipe main rib resting connection structure and the beam bottom formwork support structure of the present utility model adopt the method of resting and connecting the beam bottom formwork double-steel pipe main rib with the side vertical rods of the beam. The double-steel pipe main rib is horizontally and spacedly rested through the side vertical rod of the beam and the double-pipe side support assembly, and the bottom vertical rod of the beam bears the force through the top support. It not only solves the collision problem between the beam bottom double-steel pipe and the side vertical rods of the beam in the concrete formwork support, but also improves the weak bearing capacity of the traditional single-steel pipe at the beam bottom and reduces the safety hazards of the beam bottom double-steel pipe.
