CN201605828U - Building jacking-used concrete cushion block - Google Patents

Abstract

The utility model discloses a building jacking-used concrete cushion block, which comprises steel templates and a concrete block, wherein the four steel templates are connected into a square framework; the concrete block is poured in the framework formed by the steel templates; and the four side walls of the concrete block are fixedly connected with the corresponding steel templates. Steel templates are adopted to pour the concrete block, so that the levelness of the surface of the concrete block is ensured and the phenomena that the cushion block is damaged or crushed due to the compression are avoided. The steel templates have higher pressure resistance, so that under the surrounding and limiting of the steel templates, the bearing capacity of the cushion block is greatly improved. In addition, reinforcing mesh pieces are arranged in the concrete cushion block, so that the bearing capacity of the cushion block is improved, and the damage rate of the cushion block is reduced; and the concrete cushion block can be reused, save cost and ensure the stability and safety in the jacking process.

Description

Building jacking concrete pad

Technical field

The utility model relates to the building jacking cushion block, more particularly, relates to a kind of building jacking concrete pad.

Background technology

At present, the jacking of building is all undertaken by hydraulic jack basically.When the building of top lifting height less (in the 500mm), the building bottom is just being put or be inverted in to the general jack that adopts, and the concrete pad pad placed the jack lower end, when the jack jacking, play the effect (, generally not being suitable for the bigger occasion of top lifting height) of carrying and bed hedgehopping because concrete pad is heavier.Traditional concrete pad is general to adopt common wooden form to carry out moulding by casting, therefore there is surface irregularity, cause its ledge concentrated stress bigger, thereby the local ledge that cushion block takes place in the jacking process is easily at first damaged, is pressed by pressure crisp phenomenon, cause cushion block to damage, and it is stable that whole jacking is lost, and has serious potential safety hazard.

The utility model content

At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of building jacking concrete pad, and this cushion block guarantees surfacing, reduces impaired, the raising supporting capacity.

For achieving the above object, the utility model adopts following technical scheme:

This building jacking comprises steel form and concrete block with concrete pad, and four steel forms are linked to be square frame-like, and concrete block is cast in the framework of steel form formation, and four sidewalls of concrete block are connected and fixed with corresponding steel form.

Described concrete block inside is provided with several layers of reinforced mesh.

Be provided with spacing distance between the neighbouring two-layer reinforced mesh.

The both ends of the surface up and down of described steel form and the both ends of the surface up and down of concrete block maintain an equal level.

In technique scheme, building jacking of the present utility model comprises steel form and concrete block with concrete pad, four steel forms are linked to be square frame-like, and concrete block is cast in the framework of steel form formation, and four sidewalls of concrete block are connected and fixed with corresponding steel form.Adopt steel form fluid concrete piece can guarantee the concrete block surfacing, avoid cushion block to damage, press crisp phenomenon by pressure, and steel form to have higher compression strong, by the solid constraint of enclosing of steel form, can improve the supporting capacity of cushion block greatly; In addition, by reinforced mesh being set, also improved the supporting capacity of cushion block, thereby reduced the spoilage of cushion block in concrete block inside, reusable, save cost, and guaranteed the stable and safety of jacking process.

Description of drawings

Fig. 1 is the structure cross-sectional schematic of building jacking of the present utility model with concrete pad;

Fig. 2 is the vertical view of cushion block of the present utility model;

Fig. 3 is the use principle figure of cushion block of the present utility model.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

Please in conjunction with Fig. 1～shown in Figure 3, building jacking of the present utility model comprises steel form 11 and concrete block 12 with concrete pad 10, four steel forms 11 are linked to be square frame-like, concrete block 12 is cast in the framework of steel form 11 formation, and four sidewalls of concrete block 12 are cast for one with corresponding steel form 11.The both ends of the surface up and down of each steel form 11 and the both ends of the surface up and down of concrete block 12 all maintain an equal level.In addition, the pressure size according to using cushion block 10 to bear is provided with several layers of reinforced mesh 13 in concrete block 12 inside, and is separated with certain distance between between the neighbouring two-layer reinforced mesh 13.

The manufacturing process of this cushion block 10 is as follows: adopt four steel forms 11 to be welded into square frame-like earlier, and be arranged on the steel plate face, thereby form the punching block of concrete block 12, reinforced mesh 13 is set in punching block then, in punching block, carry out fluid concrete again, when building, only need along steel form 11 top mouths, with the floating planeness that just can guarantee cushion block 10 all surfaces of sleaker; Removing the bottom steel plate at last gets final product.

Please consult shown in Figure 3ly again, the use of this cushion block 10 is same as the prior art, in Fig. 3, adopts jack 1 to be inverted in the bottom of building thick pillar beam 2, and with this cushion block 10 with the continuous jacking of jack successively from the bottom up pad put, play jacking carrying effect.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
