Abstract
The utility model discloses a hollow building cover structure with a heightening cushion block, which is composed of a heightening cushion block, a filling tube, reinforced bars at the lower layer of a plate and concrete. The heightening cushion block is arranged on a mould under the plate, the height of the heightening cushion block equals the distance between the undersurface of the filling tube and the bottom mould, the notch of the U-shaped heightening cushion block fastens downwards the reinforced bars at the lower layer of the plate, and the reinforced bars fix the position of the cushion block. The aim of putting the undersurface of the filling tube on the top surface of the cushion block is to make sure the vertical position of the filling tube. The utility model has advantages of easy material obtaining, low cost, convenient construction and good economy and applicability.
Description
Affiliated technical field
The utility model belongs to buildings in general constructing technology field.
Background technology
In industry and civilian construction field, along with the large-span concrete structure is increasing, increasing engineering adopts the cast-in-place concrete hollow building roof technology.When at present existing hollow building cover technology is constructed at the scene, in order to guarantee that the upright position of filling pipe adheres to specification, usually adopt following two way: (1) is placed in the reinforcing bar split heads of long strip type on the template, fill pipe and be close to and be placed on above the split heads, the height of split heads equals to fill the design height of pipe soffit nadir.(2) with cement or plastic cushion pad between lower floor's reinforcing bar of filling pipe and plate, then with cushion block and lower floor's reinforcing bar binding together with iron wire.
(1) kind reinforcing bar that way consumes is many, and cost is than higher; If fill the presstressed reinforcing steel that has arrangement of curves between the pipe, numerous reinforcing bar split heads will influence effective rise of presstressed reinforcing steel, thereby influence the safety of structure.(2) kind way is simple, cheap; The machining accuracy of lower floor's bar diameter error, reinforcing bar base concrete topping construction precision, cushion block is depended in the upright position of filling pipe, and the cumulative effect of three kinds of errors is to the location construction quality of filling pipe; Cushion block and lower floor's laid reinforcement binding quality also have a direct impact the location of filling pipe in addition.In real engineering, the general control thickness of concrete cover that only plays a part of present existing cement or plastic products cushion block, height be less than≤35mm, depth of rebate≤15mm, and also construction time slot actinal surface is to reinforcing bar template arrangement dorsad.
If can adopt reasonable method, under the prerequisite that guarantees construction quality, both reduced the material cost, convenient construction is very favourable to promoting the cast-in-place concrete hollow building roof technology again.
Summary of the invention
At some shortcomings that prior art exists, the utility model main purpose provides a kind of hollow building cover structure with heightening type cushion block, and it is made of heightening type cushion block, filling pipe, plate lower floor reinforcing bar and concrete.Adopt this structure can guarantee construction quality, reduce material cost and easy construction.
The technical scheme that its technical problem that solves the utility model adopts is: produce a kind of height and equal to fill the heightening type cushion block of pipe soffit apart from the bed die distance h.The heightening type cushion block is placed on above the plate soffit formwork, and wherein the cushion block notch blocks plate lower floor reinforcing bar downwards, and reinforcing bar has been fixed the position of cushion block, has limited the move left and right of cushion block.Be placed on the top plan of cushion block filling the pipe soffit, reach the purpose that the pipe upright position is filled in accurate location.The utility model is drawn materials easily, low, the easy construction of cost, has excellent economy and applicability.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model constructional drawing.
Fig. 2 is a heightening type cushion block elevational schematic view in the utility model.
Fig. 3 is a heightening type cushion block schematic cross-sectional view in the utility model.
Among the figure: 1. the heightening type cushion block, 2. fill pipe, 3. plate lower floor reinforcing bar, 4. concrete, 5. plate soffit formwork.
The specific embodiment
The utility model is to realize in such a way:
1,, produces the heightening type cushion block (1) of shape " U " type by the distance h of design determined filling pipe (2) soffit apart from plate soffit formwork (5).Heightening type cushion block height h 〉=40mm, thickness w 〉=10mm, the cushion block bottom has the notch of 1 depth d 〉=20mm, the diameter of the width b2 of notch 〉=plate lower floor reinforcing bar (3), the plane of a width b1 〉=15mm is arranged at the cushion block top.Heightening type cushion block material therefor can be cement, metal or plastic products.
2, heightening type cushion block (1) is placed on above the plate soffit formwork (5), wherein heightening type cushion block notch blocks plate lower floor reinforcing bar (3) downwards, and reinforcing bar has limited the move left and right of heightening type cushion block, has fixed the horizontal level of cushion block.
3, will fill pipe (2) soffit and be close on the top plan that is placed on heightening type cushion block (1), heightening type cushion block height h equals to fill the distance of pipe soffit apart from plate soffit formwork (5), reaches the purpose that the pipe upright position is filled in accurate location.
Claims (3)
1, a kind of hollow building cover structure with heightening type cushion block, comprise heightening type cushion block (1), fill pipe (2), plate lower floor reinforcing bar (3) and concrete (4), it is characterized in that the heightening type cushion block is placed between filling pipe and the plate soffit formwork (5), height h equals to design the vertical distance of determined filling pipe soffit apart from the plate soffit formwork.
2, a kind of hollow building cover structure with heightening type cushion block according to claim 1 is characterized in that a plane is arranged at heightening type cushion block (1) height h 〉=40mm, thickness w 〉=10mm, depth of rebate d 〉=20mm, the top of shape " U " type.
3, a kind of hollow building cover structure with heightening type cushion block according to claim 1 is characterized in that heightening type cushion block (1) notch is stuck in above the plate lower floor reinforcing bar (3) downwards, by the fixing horizontal level of heightening type cushion block of plate lower floor reinforcing bar.
