Cast-in-place concrete hollow filler wall

Technical Field

The utility model belongs to the technical field of building engineering, concretely relates to non-bearing wall structure.

Background

At present, non-bearing walls of buildings are mostly built by autoclaved aerated concrete blocks, and the conventional method is that after the pouring of a main structure of the building is completed, a template is dismantled and a maintenance period is reached, and the insertion construction is started after the material transportation conditions are met on site. The process is easy to generate shrinkage cracks between the concrete structure and the filling wall body due to different thermal expansion coefficients of the building block material and the main structure, and finally the wall body cracks and leaks to influence the use function and the attractiveness of the building. Meanwhile, the method also has the defects of more construction procedures, slow progress, large material loss, high construction cost and the like.

Disclosure of Invention

The purpose of the utility model is realized through the following technical scheme.

The utility model provides a cast in situ concrete hollow infilled wall, is including setting up the vertical PVC hollow tube of a row of sequence arrangement in the infilled wall, the reinforcing bar cuff of cover outside the hollow tube of PVC in groups, set up respectively in the flexible isolator that is arranged in the gap between infilled wall and the building major structure at infilled wall both sides and top, set up in the infilled wall and be located the latticed structure muscle of both sides around the PVC hollow tube, the upper and lower end of PVC hollow tube is the shutoff end.

Further, the flexible spacer is a polystyrene board.

Furthermore, connecting lacing wires are transversely connected between the latticed structural ribs on the front side and the rear side.

Further, the diameter ratio of PVC hollow tube is 50mm less than infilled wall thickness and does, highly is 50mm shorter than infilled wall net height.

The utility model discloses take pre-buried PVC hollow tube in non-bearing wall body, reducible concrete dosage alleviates the wall body dead weight. The joint of the filler wall and the main structure is flexibly connected and isolated from the main structure, so that the adverse effect of a non-bearing wall body on the rigidity of the main structure can be reduced. The structural steel bars are arranged in the wall body, so that good bonding force can be formed between the wall body and concrete, and the shrinkage and creep of the concrete are reduced. The utility model discloses the wall body can be under construction simultaneously with major structure, and integral erection for the construction progress, reduction of erection time has effectively solved traditional packing wall body fracture, seepage and the long problem of construction period.

Detailed Description

The present invention will be further explained with reference to the drawings and the embodiments.

As shown in fig. 1, 2 and 3, the cast-in-place concrete hollow infilled wall is used for a non-load-bearing wall body. The PVC hollow pipe comprises a row of vertical PVC hollow pipes 2 arranged in sequence in a filler wall 1, a reinforcing steel bar hoop 3 sleeved outside the grouped PVC hollow pipes, flexible isolation bodies 4 arranged on two sides and the top of the filler wall respectively and positioned in gaps between the filler wall and a building main structure 7, latticed construction ribs 5 arranged in the filler wall and positioned on the front side and the rear side of the PVC hollow pipes, and connecting tie bars 6 for connecting the latticed construction ribs on the front side and the rear side. The upper end and the lower end of the PVC hollow pipe 2 are plugging ends which can be plugged by an end plugging cover or plugged by other prior art means. The end cap is commercially available. The flexible isolation body 4 is made of polystyrene board, and other flexible materials suitable for the prior art can also be adopted. Generally, the diameter of the PVC hollow pipe 2 is 50mm smaller than the thickness of the wall, and the length of the PVC hollow pipe is 50mm shorter than the net height of the wall, so that a concrete layer outside the PVC hollow pipe after concrete is poured on the wall has a certain thickness, and the PVC hollow pipe cannot be exposed. The vertical bars and the horizontal bars of the latticed structural bars 5 are all made of steel bars, binding connection is carried out on the vertical bars 5a and the horizontal bars 5b through binding wires 8 (only the binding wire of one connecting node is schematically drawn in fig. 1), and two ends of the horizontal bars of the latticed structural bars are anchored into the building main body structures 7 on two sides. The latticed structure ribs on the front side and the rear side of the filler wall are connected through connecting tie bars 6 with hooks at two ends, the hooks at two ends of the connecting tie bars pull the transverse ribs or the vertical ribs of the latticed structure ribs on the two sides, and the latticed structure ribs on the two sides are connected and positioned so as to avoid displacement during concrete pouring. The reinforcing steel bar hoop 3 is used for hooping a group of PVC hollow pipes which are sequentially arranged, so that the PVC hollow pipes are hooped into a whole, and the PVC hollow pipes are prevented from shifting when concrete is poured. The upper opening and the side surface of the infilled wall are flexibly connected with the joint of the main building structure by using the polystyrene board, the polystyrene board which is well laid is embedded into the joint between the side surface of the infilled wall and the main building structure 7 and the joint between the top surface of the infilled wall and the structural beam of the main building structure 7, and the polystyrene board and the structural rib 5 are firmly bound by using the binding wire.

During construction, the PVC hollow pipes which are well fed are sequentially placed into the filling wall body according to the positioning size before steel bar binding is constructed, and the PVC hollow pipes are grouped and hooped by the steel bar hoops 3. And (3) inversely inserting the vertical ribs of the latticed structural ribs into the structural beams of the building structure main body before the floor slab is poured, and anchoring two ends of the transverse ribs into the building main body structures at two sides. Then, thick polystyrene boards are arranged at the opening and two side surfaces of the infilled wall, the joint between the infilled wall and the main structure of the building is flexibly connected, and the infilled wall is firmly bound with the structural ribs by binding wires. The formwork system of the infilled wall and the formwork systems of the building main structures on two sides form a whole, concrete is poured into the formwork frame, the infilled wall and the building main structures are simultaneously poured and formed, and the integral pouring structure of the infilled wall 1 and the building main structures 7 is formed as a whole as shown in fig. 3.

Under the condition of the same unit volume, the volume ratio and the setting number of the PVC hollow pipes in the non-bearing wall body can be obtained through the comparison calculation of the volume weight of the reinforced concrete and the volume weight of the filled wall body, so that the self-weight load of the PVC hollow pipes meets the design requirement. The structural ribs are arranged in the wall according to the minimum reinforcement ratio of the non-seismic member, so that better bonding force is formed with concrete, and the shrinkage and creep of the concrete are reduced. Such calculations and designs are well within the skill of those in the art based on actual building design requirements.

The utility model discloses a non-bearing wall body and building major structure integral erection have saved the loaded down with trivial details process in later stage for construction speed has improved construction quality.
