Abstract
The utility model provides a dowel bar fixing device for a large-area ground construction joint, and is applied to the large-area special ground construction joint of an industrial factory building. The dowel bar fixing device comprises a dowel bar (8) and a dowel bar fixing device, wherein the dowel bar fixing device is a right-angle triangular supporting frame; a first template (3) is arranged at one end of a horizontal included angle of the right-angle triangular supporting frame; and one end of the dowel bar (8) is fixed on the first template (3), and the other end of the dowel bar (8) passes through a hole in the middle of a second template (7) and is vertical to the face of the second template (7). The dowel bar fixing device provided by the utility model has the advantages of firm fixation of the dowel bar, simple structure and convenience in construction. With the adoption of the dowel bar fixing device, the general problem in quality that a faulting phenomenon is generated at the position of the construction joint because two boards are stressed unevenly at the construction joint, can be effectively prevented.
Description
Technical field
The dowel bar fastening devices at a kind of large tracts of land ground construction joint place is applied to the extraordinary ground construction joint of the large tracts of land place of industrial premises etc.
Background technology
Development along with modernization industry; Industrial premises requires increasingly high to the extraordinary ground quality of planeness, crack resistance, impact resistance and the abrasion resistance etc. of terrace; Especially for the extraordinary ground of large-area industrial premises; How in the short construction period, reach high-caliber quality requirement, also need on ground construction technology, to innovate and improve.The extraordinary ground construction joint place of large tracts of land factory building is provided with the dowel bar system, guarantees the load transfer ability and the planeness on ground of seam crossing, prevents that faulting of slab ends from appearring in seam crossing is the problem that presses for solution, and does not also have a technology that really can address the above problem at present.
Summary of the invention
The technical problem that the utility model will solve is: overcome the problem that prior art exists; Design a kind of simple in structure, easy construction; Prevent the constuction joint place because two plate discontinuity make the constuction joint place produce the dowel bar fastening devices at the large tracts of land ground construction joint place of common quality defect problems such as faulting of slab ends.
The technical scheme that its technical problem that will solve the utility model adopts is: the dowel bar fastening devices at this large tracts of land ground construction joint place; It is characterized in that: comprise dowel bar and dowel bar fastening devices; The dowel bar fastening devices is a right angle trigonometry shape bracing frame; Right angle trigonometry shape bracing frame horizontal sextant angle one end is provided with first template, and an end of dowel bar is fixed on first template, and the other end passes in the hole at second template middle part and keeps vertical with the second template face.
Described right angle trigonometry shape bracing frame be included in again horizontal support that ground cushion top is provided with, with the vertical support of horizontal support vertical fixing; The vertical support outside is second template; Establish the elongated lumps of wood between second template and the vertical support; Be connected to become the right angle trigonometry shape through oblique connecting rod, steel nail vertically passes on first lumps of wood that first template is fixed on the horizontal support outside.
Described horizontal support and vertical support are the lumps of wood and make, and first template and second template are made for the bamboo offset plate.
Operating principle
Because dowel bar one end is anchored on first template; Center fixed is on second template; Guarantee that on the one hand the dowel bar position can not send out skew; Concrete to guarantee two plates in Concrete Construction seam place is stressed jointly, prevents because two plate discontinuity make the constuction joint place produce common quality defect problems such as faulting of slab ends.Guaranteed the Construction of Ground quality.
Compared with prior art; The beneficial effect that the dowel bar fastening devices at the large tracts of land ground construction joint place of the utility model is had is: simple in structure, easy construction; The dowel bar fixation; Effectively prevent the constuction joint place because two plate discontinuity make the constuction joint place produce common quality defect problems such as faulting of slab ends.Utilize the force transfer system construction technology technology at this large tracts of land ground construction joint place advanced, effect is remarkable aspect raising ground quality, shortening construction period, so have obvious social and economic benefit.
Description of drawings
Fig. 1 is the structural representation of the dowel bar fastening devices at the utility model large tracts of land ground construction joint place.
Wherein: 1 ground cushion, 2 first lumps of wood, 3 first templates, 4 horizontal supports, 5 vertical support, the 6 elongated lumps of wood 7 second templates 8 dowel bars.
Fig. 1 is the most preferred embodiment of the utility model, further specifies below in conjunction with the dowel bar fastening devices at the large tracts of land ground construction joint place of 1 pair of the utility model of accompanying drawing:
The specific embodiment
As shown in Figure 1:
The dowel bar fastening devices at this large tracts of land ground construction joint place is made up of ground cushion 1, first lumps of wood 2, first template 3, horizontal support 4, vertical support 5, the elongated lumps of wood 6, second template 7 and dowel bar 8.Mainly comprise dowel bar 8 and right angle trigonometry shape bracing frame two parts; Right angle trigonometry shape bracing frame horizontal sextant angle one end is provided with first template 3; One end of dowel bar 8 is fixed on first template 3, and the other end passes in the hole at second template, 7 middle parts and be vertical with 7 maintenances of second template.
Described right angle trigonometry shape bracing frame be included in again horizontal support 4 that ground cushion 1 top is provided with, with the vertical support 5 of horizontal support 4 vertical fixing; Vertical support 5 outsides are second template 7; Establish the elongated lumps of wood 6 between second template 7 and the vertical support 5; Be connected to become the right angle trigonometry shape through oblique connecting rod, steel nail vertically passes on first lumps of wood 2 that first template 3 is fixed on horizontal support 4 outsides.
Described horizontal support 4 is the lumps of wood with vertical support 5 and makes, and first template 3 and second template 7 are made for the bamboo offset plate.
Installing and fixing of first template 3, second template 7 and dowel bar 8:
(1) second template 7 can adopt the bamboo offset plate, should guarantee enough intensity;
(2) steel nail vertically passes on first lumps of wood 2 that first template 3 is fixed on horizontal support 4 outsides, guarantees that the position accurately, firmly;
(3) second templates 7 inboards are cleaned out and the brushing interleaving agent;
