Description
Technical field
The utility model belongs to the realm of building construction, especially a kind of formwork structure of concrete construction joint.
Background technology
Constuction joint refers to it is in concreting process, because designing requirement or construction need segmentation to build formerly, the seam that formed between the concrete of after-pouring.Constuction joint is not a kind of " seam " of necessary being, and it is just because after-pouring concrete exceedes the initial setting time, and and between the concrete of first building, there is a bonding surface, this bonding surface is just referred to as constuction joint.
Therefore need secondary concreting at constuction joint place, or due to concrete class different with seepage resistance demand, concrete obstruct need be carried out and pick chiseler do.If deal with improperly, not only have a strong impact on building attractive in appearance, also can cause the defects such as folder quarrel, layering, rotten seepage.Traditional construction joint formwork adopts bamboo slab rubber or wood glue plate, punches onboard in the position according to reinforcing bar, or adopts gauze wire cloth to carry out installation in position, and be aided with sponge strip, adhesive tape carrys out mortar leakage prevention; But because the contrast locating of plate hole and gauze wire cloth is more difficult, so often there will be spillage phenomenon.Gauze wire cloth and bamboo (wood) offset plate all should be rejected after concrete formation, and the concrete will built early stage before building next time picks cutter process, so not only waste a large amount of manpower and materials, and effect is often unsatisfactory.
Through retrieval, find one section of patent document relevant to present patent application: a kind of Novel construction joint formwork, notification number (CN203795843U), this publication discloses rigid backbone, and described rigid backbone is provided with fast-easy closing-up net.
Contrasted by technical characteristic, above-mentioned open source literature and Problems existing are: 1, fast-easy closing-up net installs inconvenience, especially when installing the upper and lower part reinforcing bar at constuction joint place; 2, formwork integral is fixed insecure.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of structure is simple, easy for installation, the formwork structure of the concrete construction joint of fixation.
Scheme of the present utility model is achieved in that
A kind of formwork structure of concrete construction joint, comprise fast-easy closing-up net and rigid backbone, described fast-easy closing-up net is vertically arranged, and the outside-supporting of this fast-easy closing-up net has rigid backbone, and the upper and lower edge uniform intervals of described fast-easy closing-up net is shaped with the rectangular recess of multiple accommodation upper and lower parts reinforcing bar; Described rigid backbone comprises horizontal fixing reinforcing bar and perpendicular bearing bar, and described horizontal fixing reinforcing bar is installed in the V-type groove of fast-easy closing-up net, and this horizontal fixing reinforcing bar is fixed with the spaced multiple perpendicular bearing bar of horizontal homogeneous.
And the fast-easy closing-up net upper/lower terminal portion outside described rigid backbone is horizontally installed with flitch.
And, laterally steel plate for sealing water is installed in the middle part of described fast-easy closing-up net.
Advantage of the present utility model and good effect are:
1, the fast-easy closing-up net in this template has a large amount of grids, directly therefrom can observe concrete building and situation of vibrating.Compared with conventional template, effectively can reduce and owe to shake or cross phenomenon of shaking, reduce risk and the probability of the defect appearance such as honeycomb, hole, bubble, pitted skin.
2, be convenient to wear muscle and be connected assembling reinforcement, by being shaped with multiple rectangular recess at the upper and lower edge of fast-easy closing-up net, being convenient to and upper and lower part reinforcement installation, increasing work efficiency.
3, be easy to construction, this template is easy to cutting and bends, and can bend or excision forming according to required modular form.
4, the utility model structure is simple, design science reasonable, constructability, not only effectively improves operating efficiency, not easily occurs spillage phenomenon, and improve integrally-built firmness and stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A formwork structure for concrete construction joint, as shown in Figure 1 and Figure 2, comprise fast-easy closing-up net 2 and rigid backbone, described fast-easy closing-up net is vertically arranged, and the outside-supporting of this fast-easy closing-up net has rigid backbone.
Innovative point of the present utility model is:
1, the upper and lower edge uniform intervals of described fast-easy closing-up net is shaped with the rectangular recess 8 of multiple accommodation upper and lower parts reinforcing bar 4 (upper reinforcement 4A, lower rebar 4B), and the effect of this rectangular recess is the upper and lower part reinforcing bar being convenient to install concrete wall 1.
2, described rigid backbone comprises horizontal fixing reinforcing bar 6 and perpendicular bearing bar 3, and described horizontal fixing reinforcing bar is installed in the V-type groove 5 of fast-easy closing-up net, and this horizontal fixing reinforcing bar is fixed with the spaced multiple perpendicular bearing bar of horizontal homogeneous.This rigid-skeleton simple and and fast-easy closing-up net between installs firm, improve stability and the fastness of whole template.
3, the fast-easy closing-up net upper/lower terminal portion outside described rigid backbone is horizontally installed with flitch 7.
When 4, constructing at poured band of outer wall of basement constuction joint place, laterally install steel plate for sealing water (not shown) in the middle part of fast-easy closing-up net, the perpendicular bearing bar of fast-easy closing-up net and steel plate for sealing water take spot welding to fix.
Rigid backbone in the utility model and fast-easy closing-up net are all by together with steel wire lashing.
The utility model has the advantages of for:
1, the fast-easy closing-up net in this template has a large amount of grids, directly therefrom can observe concrete building and situation of vibrating.Compared with conventional template, effectively can reduce and owe to shake or cross phenomenon of shaking, reduce risk and the probability of the defect appearance such as honeycomb, hole, bubble, pitted skin.
2, be convenient to wear muscle and be connected assembling reinforcement, by being shaped with multiple rectangular recess at the upper and lower edge of fast-easy closing-up net, being convenient to and upper and lower part reinforcement installation, increasing work efficiency.
3, be easy to construction, this template is easy to cutting and bends, and can bend or excision forming according to required modular form.
4, the utility model structure is simple, design science reasonable, constructability, not only effectively improves operating efficiency, not easily occurs spillage phenomenon, and improve integrally-built stability.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in detailed description of the invention; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
