Adopt the utility model discloses a trade and prop the mode, first one supports the demolition time and need not wait again and has built being connected between structure bottom plate and the new construction and accomplish and reach the strength requirement and can go on, only need guarantee in the floor and this trade prop pass power structure intensity and reach the requirement can removable the propping, can practice thrift basement construction cycle greatly.
Description
Technical Field
The utility model relates to a new and old structure multilayer basement construction technology, especially a new and old structure multilayer basement trades and props biography power structure.
Background
At present, basements are constructed in stages, and after a basement construction stage of post-construction faces support dismantling, support replacing parts do not have support structures. The main reason is that the connecting parts of the new and old structures cannot be constructed in advance in time. In order to ensure that the support is smoothly dismantled firstly and ensure the normal construction of the basement structure, a new and old structure multi-layer basement support-changing force-transferring structure needs to be designed.
Disclosure of Invention
The invention provides a new and old structure multi-layer basement support-changing force-transferring structure, wherein a force-transferring structure is formed by utilizing an enclosing purlin at a joint, a reserved second supporting part between the enclosing purlin and an outer wall, a middle floor and an auxiliary part between the middle floor and the outer wall before the connection part of the new and old structure is not constructed, so that an effective support-changing force-transferring belt is formed before an upper support is dismantled, and the normal and smooth construction of an underground structure is ensured.
The technical scheme of the utility model is that: the utility model provides a new and old structure multilayer basement trades props biography power structure, enclose the body enclosing purlin including new and old building handing-over department, the basement outer wall, newly-built underground one, well floor between the two layers, it says that the support part is as biography power support to leave the second between enclosing the body enclosing purlin of new and old building handing-over department and the basement outer wall, the second that stays to establish is said and is supported and plant the reinforcing bar and anchor into the basement outer wall, the difference in height between basement outer wall and the well floor is ensured through adding the armpit part between basement outer wall and the well floor that the upper strata supports and forms one effectual biography power area of propping that trades before demolising to ensure that secret one deck structure is normally under construction smoothly.
Furthermore, the haunching part is triangular, the size of the triangle is matched with the height difference of the middle floor slab with a second support arranged outside the outer wall of the basement, the inner reinforcing steel bars of the triangle are connected with the outer wall of the basement and the middle floor slab, and concrete is poured through the templates after the reinforcing steel bars are bound to form the haunching part structure.
Furthermore, reinforcing steel bars are arranged in the joints of the basement outer wall and the haunched parts and are fixedly connected with the reinforcing steel bars in the haunched parts, and the haunched parts are anchored with the basement outer wall and the middle floor through the reinforcing steel bars to form a whole.
The utility model has the advantages that:
adopt the utility model discloses a trade and prop the mode, first one supports the demolition time and need not wait again and has built being connected between structure bottom plate and the new construction and accomplish and reach the strength requirement and can go on, only need guarantee in the floor and this trade prop pass power structure intensity and reach the requirement can removable the propping, can practice thrift basement construction cycle greatly.
Under the guarantee of the belt transmitted by the support changing, the connection between the bottom plate of the built structure and the new structure can be constructed according to the actual construction period, the construction can be completed at one time, and the construction quality is more guaranteed.
The basement beam slab adds the armpit and is the relatively independent structure, can not demolish after the underground structure construction is accomplished, plays certain stiffening action to the structure itself simultaneously. The movable wall can be removed according to the needs of construction units, and the main structure cannot be affected.
Drawings
Fig. 1 is the utility model discloses a new and old structure multilayer basement trades to prop and passes power structure sketch map.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings and examples.
As shown in figure 1, the new and old structure multi-layer basement support-changing force-transferring structure comprises a built structure bottom plate 3, a newly-built underground first layer 1, a newly-built underground second layer 2, an enclosing body enclosing purlin 5 at the joint of the new and old building, a basement outer wall 6, a newly-built middle floor plate 8 between the underground first layer and the newly-built underground second layer, and a second support part 7. The second supporting part 7 is reserved between the enclosing purlin 5 of the new building and the old building at the joint of the built bottom plate and the newly-built structural connecting section 4 and the basement outer wall 6 to serve as force transferring support, the armpit part 9 is additionally arranged between the basement outer wall 6 and the middle floor plate 8 to form a force transferring structure, an effective force transferring belt is formed before the upper support is detached, and the normal and smooth construction of the underground structure is guaranteed.
In this embodiment, haunching part 9 is triangle-shaped, and triangle-shaped size depends on the support and the well floor difference of setting up of remaining outside the basement outer wall, and triangle-shaped's inside reinforcing bar connects basement outer wall and well floor, pours concrete through the template after the reinforcement and forms haunching part structure. Reinforcing steel bars 10 are arranged in the joints of the basement exterior wall 6 and the haunching parts 9 and are fixedly connected with the reinforcing steel bars in the haunching parts through the reinforcing steel bars 10.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. All the equivalent structural changes made by the contents of the specification and the drawings of the present invention are included in the scope of the present invention.
