[0002] The non-slab frame system is a form of building structure that is different from the traditional floor frame structure. In the traditional floor frame structure, the floor slab usually serves as a horizontal support to help distribute and transfer the load to the columns and foundation. The non-slab frame system does not rely on the floor slab to distribute the load, but achieves this function through other means. The non-slab frame system has been widely used due to its advantages such as spatial flexibility, structural efficiency, and simple construction.

[0003] In the process of structural construction of the frame system without floor slab, it is necessary to set up a support frame to assist the construction. In the current structural construction process of the frame system without floor slab, the upper columns and beams are often constructed by setting up a full-floor support frame. In this support structure and construction method, the amount of support setting up and dismantling is large, which leads to low construction efficiency, long construction period and high cost; and when the interface of the beam is too large, the effective transfer of load cannot be guaranteed.

The base bracket 1 includes two angle steels arranged back to back and fixedly connected by a connecting piece. That is, the flat surfaces of the two angle steels are arranged opposite to each other, and a round steel is arranged between the two angle steels and welded to form a base bracket 1. The base bracket 1 is formed by arranging two angle steels fixed by round steel welding, so that the stability and strength of the base bracket 1 are fully guaranteed.

The two ends of the transverse tie rod 3 are respectively provided with threaded parts, and the threaded parts are sleeved with a clamp 4 and locked by bolts. During the construction of the floor frame system, at least two transverse through holes are reserved through the PVC pipe during the construction of the frame beam for the subsequent penetration of the transverse tie rod 3. The two ends of the transverse tie rod 3 are respectively provided with threaded structures, and after the two ends of the transverse tie rod 3 penetrate the cross bar, the clamp 4 is sleeved thereon and locked by nuts. The two clamps 4 at the two ends of the transverse tie rod 3 are respectively located on the outside of the two cross bars and are close to the cross bars, so that the cross bars are close to the outside of the frame beam, and the base brackets 1 on both sides are fixed and locked. The clamp 4 is a mountain-shaped clamp, that is, a protruding structure is provided in the middle of the clamp 4, and concave notches are provided on both sides of the protruding structure, so that the relevant structure can be stably fixed.

That is, the cross arm 2 includes two channel steels, the flat surfaces of the channel steels are arranged opposite to each other, and then the two channel steels are welded and fixedly connected by round steel. Other methods such as bolt locking and fixed connection can also be used. The length of the round steel, that is, the gap between the two channel steels is consistent with the gap between the two angle steels of the base bracket 1. Its specific size is determined according to the size of the transverse tie rod 3 and the oblique tie rod 6. It needs to be slightly larger than the size of the tie rod so that the tie rod can pass through. The gap formed between the adjacent two round steels can also be used to form a limit on the tie rod.

The clamp 4 is locked by a nut to achieve fixed locking between the cross arm 2 and the base bracket 1. There are multiple adjustment slots, so that the corresponding adjustment slot can be selected for use according to actual conditions.

[0032] The working principle of the utility model: during the construction of the frame system without floor slab, two holes for the transverse tie rods 3 are reserved through the PVC pipe when constructing the frame beam. When constructing the upper frame beam, the base bracket 1 is installed on both sides of the lower frame beam. The base bracket 1 is installed on both sides of the frame beam by tightening the fastening bolts on both sides of the transverse tie rod 3.

It can play a role in the construction of the frame beam-column system without floor slab, realize the formwork construction on the beam, and has a good application prospect.

[0033] Specifically, two horizontal PVC pipes are embedded in advance during the construction of the lower frame beams. The inner diameter of the PVC pipe is 2 mm larger than the diameter of the horizontal tie rod 3. The plane spacing of the PVC pipes is determined according to the longitudinal span calculated by the upper beam bracket, and the vertical spacing matches the slot of the horizontal tie rod 3 of the base bracket 1. The base bracket 1 is inserted into the slot of the horizontal tie rod 3 through the horizontal tie rod 3 to fix the base bracket 1 on the lower frame beam.
