Background

At present, in actual life, the civil public buildings and industrial buildings are generally high in floor height, and most of the built public buildings and industrial buildings are cast-in-place concrete frame structures or all-steel structures. The cast-in-place concrete structure has the defects of high formwork erecting and long construction period, the existing precast concrete frame structure has the problems of secondary pouring and steel bar collision at a node, in order to avoid the problems, the section size of a component is often increased, or a bracket is even made, or a steel bar hole is reserved when a formwork is precast in a factory, so that the separate design and processing are needed, and the construction cost is increased. For building a large-size column net building structure, prestress is sometimes needed, so that the construction cost is higher and the construction period is longer. And the adoption of the all-steel structure has the problem of fire prevention. However, whether a public building or an industrial building is built by adopting a concrete frame structure or an all-steel structure, a large number of scaffolds need to be built in advance, and the scaffolds are used for supporting a roof, a wall and a floor slab. The investment cost for setting up the scaffold is high, and a long time is needed. In addition, the phenomenon that the scaffold topples over happens occasionally for there is the potential safety hazard in the construction.

The end parts of the extending ends of the first reinforcing steel bar column, the second reinforcing steel bar column and the third reinforcing steel bar column are all of circuitous bending structures.

The utility model relates to an energy-conserving stable building structure belongs to concrete frame structure. The utility model discloses a wall body is pour precast concrete wall in advance, establishes precast concrete wall immediately in subaerial hole base again, makes the boss that distributes in the hole base inlay in establishing the recess in precast concrete wall bottom surface, forms the chamber of pouring that is used for filling cast in situ concrete, to pouring the intracavity and filling cast in situ concrete, can fix the wall body in the hole base after waiting cast in situ concrete to can reach concrete frame structure's intensity requirement. The utility model discloses a precast concrete wall still can splice to satisfy the wall body setting needs of large tracts of land building. Adopt the utility model discloses a building structure when buildding public building or industrial building, because precast concrete wall is pour in advance, can shorten on-the-spot construction cycle greatly. Additionally, the utility model discloses a building structure need not the workman and carries out high altitude construction, can avoid the scaffold frame to empty or the workman falls the emergence of accident effectively, has not only improved construction's security, has still reduced construction cost.

Detailed Description

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the utility model relates to an energy-conserving stable building structure, including precast concrete wall 1 and pit foundation 2, precast concrete wall 1 is the concrete wall who has pour in advance, and pit foundation 2 is according to the construction drawing dig the pit groove of establishing precast concrete wall 1 that is used for setting up that is established well subaerial in the proposed construction area.

As shown in fig. 1 and 3, a plurality of grooves 3 are uniformly distributed on the bottom surface of the precast concrete wall 1 along the length direction thereof, and a plurality of first reinforcement columns 4 extending to the notches of the grooves 3 are distributed on the bottoms of the grooves 3. A plurality of bosses 5 corresponding to the grooves 3 on the precast concrete wall 1 are distributed on the bottom surface of the pit in the pit foundation 2, and a plurality of second reinforcing steel columns 6 extending upwards are distributed on the bosses 5. When the precast concrete wall 1 is vertically arranged in the pit foundation 2, the boss 5 in the pit foundation 2 is correspondingly embedded into the groove 3, a gap is reserved between the upper surface of the boss 5 and the bottom of the groove 3, the gap forms a pouring cavity 7 filled with cast-in-place concrete 8, a plurality of pouring ports 9 are formed in the wall surface of the precast concrete wall 1, each pouring port 9 corresponds to one pouring cavity 7 and is communicated with the pouring cavity 7, and the pouring ports 9 are used for filling the cast-in-place concrete 8 into the pouring cavities 7, as shown in fig. 5. The height of the first reinforced column 4 and the height of the second reinforced column 6 in the pouring cavity 7 are not higher than the height of the pouring cavity 7, so that the prefabricated concrete wall 1 is difficult to place stably under the action of the first reinforced column 4 or the second reinforced column 6, and the stability and the construction progress of the wall are influenced.

A plurality of third reinforced columns 12 are uniformly distributed on the end surfaces of the two side ends of the precast concrete wall 1, and the third reinforced columns 12 extend outwards from the end surfaces of the two sides of the precast concrete wall 1, as shown in fig. 1, and are used for splicing two adjacent precast concrete walls 1, so that the requirement of a large-area wall body is met. The utility model discloses correspond the overlap joint through the steel wire at the third reinforcing bar post 12 of the butt joint 10 department of putting good double-phase adjacent precast concrete wall 1 and fix together, form the reinforcing bar fixed bolster to increase the stability of wall body, fix after well to the butt joint 10 department pack cast in situ concrete 8, just accomplish the concatenation of two precast concrete walls 1 after waiting the concrete setting. The process of splicing the precast concrete wall 1 can be performed before the process of vertically arranging the precast concrete wall 1 in the pit foundation 2, so that the workers can be prevented from working high above the ground, and potential safety hazards are reduced. The completed state of the two precast concrete walls 1 can be seen in fig. 6.

In order to facilitate the hoisting of the precast concrete wall 1, a plurality of hoisting blocks 11 are distributed on the wall surface of the precast concrete wall 1 so as to facilitate the hoisting and hooking.

After the completion is built to the wall body, first reinforced column 4, second reinforced column 6 and third reinforced column 12 on the wall body all solidify in the concrete, in order to increase the steadiness of wall body and make the junction more firm, the utility model discloses a tip of the extension end of first reinforced column 4, second reinforced column 6 and third reinforced column 12 all designs into circuitous bending structure to prevent that the reinforced column from receiving the too big condition of deviating from in the concrete of pouring of pulling force and appearing.
