Description
Technical field
The invention belongs to construction timber technical field, relate to a kind of concrete combined board, particularly the concrete combined board of built-in right-angled intersection hollow square steel pipe.
Background technology
Current, in China's industry with civilian construction, because raw material are extensive, technology maturation, cheap, reinforced concrete structure is still the architecture structure form be most widely used.But, along with the raising of living standard and china's overall national strength, modern architecture is to floor height, flexibly interval and large span, the requirement of large space is more and more urgent, and this just requires that design of building structures personnel must be devoted to study new, more comfortable, the better reinforced concrete structure system of techno-economic effect.Current building floor has generally adopted beam slab or chainless drives, owing to there being beam slab can not meet the requirement of building clear height and add floor height in this system, is unfavorable for antidetonation; And traditional chainless drives is heavy due to himself, easily produces amount of deflection, crack, the requirement of building large space, large span cannot be used for.Therefore, find and a kind ofly can meet building function and require reduce again the new structure form of construction costs, particularly important to solve large bay, large span floor.
Summary of the invention
Object of the present invention for traditional cast-in-place concrete floor from great, easy generation degree of disturbing, crack, the shortcoming of large space, large span cannot be used for, a kind of concrete combined board of built-in right-angled intersection hollow square steel pipe is proposed, object be realize a kind of supporting capacity high, not only to have met the new structure form that building function requires but also can reduce cost from heavy and light, easy construction.
Technical scheme of the present invention is: the concrete combined board of built-in right-angled intersection hollow square steel pipe, comprise horizontal square steel pipe, longitudinal square steel pipe, reinforcing bar, bottom template and concrete, it is characterized in that: form square steel tube layer by horizontal square steel pipe and longitudinal square steel pipe, described horizontal square steel pipe and described longitudinal square steel pipe are welded to each other and form cross-shaped square steel tube layer, described reinforcing bar is arranged along X and Y-direction and forms two-way concrete slab layer, described two-way concrete slab layer is laid on described square steel tube layer above and below, described square steel tube layer and described bottom template are by lower hanging bar connecting, after the colligation of described two-way concrete slab layer, the concrete combined board of right-angled intersection hollow square steel pipe is formed after building described concrete.
Described longitudinal square steel pipe inboard is elongated, and the both sides that horizontal square steel pipe is welded on longitudinal square steel pipe form cross-shaped.
Described horizontal square steel pipe and longitudinal square steel pipe cross section are rectangle, and the depth of section of longitudinal square steel pipe is greater than horizontal square steel pipe depth of section.
Described bottom template can be wooden form or steel form.
Described two-way concrete slab layer by reinforcing bar in X direction and Y-direction interval be evenly arranged.
Beneficial effect of the present invention is: the concrete combined board of built-in right-angled intersection hollow square steel pipe provided by the invention, structurally right-angled intersection hollow square steel tube layer is placed between two-way concrete slab layer, its bearing capacity is large, under the condition of same bearer power, more common floor weight is lighter, and thickness is less, improves floor clear height, reduce cost, can be applicable in the structure of the large load of large span; The rigidity of structure is good, and floor bulk deformation is very little, good integrity; In floor level, supporting capacity is high, and opposing horizontal earthquake action ability is strong; Cross hollow steel pipe can processing factory prefabricated, quality is easy to be guaranteed, and construction machinery rate is high; Hang mould construction during construction, easy construction, the reduction of erection time, save template.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As Figure 1-4, the concrete combined board of built-in right-angled intersection hollow square steel pipe, comprise horizontal square steel pipe 1, longitudinal square steel pipe 2, reinforcing bar 4, bottom template 6 and concrete 3, square steel tube layer is formed by horizontal square steel pipe 1 and longitudinal square steel pipe 2, horizontal square steel pipe 1 is welded to each other with longitudinal square steel pipe 2 and forms cross-shaped square steel tube layer, reinforcing bar 4 is arranged along X and Y-direction and forms two-way concrete slab layer 5, two-way concrete slab layer 5 is laid on square steel tube layer above and below, square steel tube layer is connected by lower hanging reinforcing bar 7 with bottom template 6, after two-way concrete slab layer 5 colligation, the concrete combined board of right-angled intersection hollow square steel pipe is formed after concreting 3.
As Figure 1-4, the concrete combined board of built-in right-angled intersection hollow square steel pipe, longitudinal square steel pipe 2 is inboard elongated, and the both sides that horizontal square steel pipe 1 is welded on longitudinal square steel pipe 2 form cross-shaped square steel tube layer; Horizontal square steel pipe 1 is rectangle with longitudinal square steel pipe 2 cross section, the depth of section of longitudinal square steel pipe (long span direction) 2 is greater than horizontal square steel pipe (short in direction) 1 depth of section, long span and short across selection need determine according to compoboard use occasion, usually be long span at length direction, width be short across; Whole right-angled intersection hollow square steel tube layer forms an entirety, improves bearing capacity in floor level, arranges two-way concrete slab layer in the top and bottom of square steel tube layer simultaneously, two-way concrete slab layer 5 by reinforcing bar 4 in X direction and Y-direction interval be evenly arranged; Square steel pipe is placed between two-way concrete slab layer; Simultaneously according to actual needs can to the arch camber of hollow square steel pipe to reduce the degree of disturbing of large-span cast-in-situ plate.
As Figure 1-4, the concrete combined board of built-in right-angled intersection hollow square steel pipe, right-angled intersection hollow square steel tube layer is first lifted in work progress, then hanging reinforcing bar 7 under welding in square steel tube layer, to sling bottom template 6 with lower hanging reinforcing bar 4, the gravity load of whole bottom template 6 is all delivered in right-angled intersection hollow square steel tube layer by lower hanging reinforcing bar 7, after bottom template 6 has lifted, arranges colligation plate double-layer double-direction steel bar layer 5.Because large-span cast-in-situ plate thickness of slab is often thicker, lower hanging reinforcing bar 7 can not bear load that once-pouring of concrete produces therefore can divide secondary concreting.
