Drawings
FIG. 1 is a schematic structural diagram of the present embodiment;
the device comprises a wood pattern, a clamping groove, a bolt, a clamping groove supporting structure and a clamping groove supporting structure, wherein the wood pattern comprises 2-a wood pattern, 3-a clamping groove, 4-a bolt, 5-a clamping groove supporting structure and 6-a wood pattern supporting structure.
Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
Example 1:
as shown in fig. 1, in this embodiment, a side form of a cast-in-place hollow landscape arch bridge with a special-shaped cross section includes a clamping groove 3 with an opening facing a side surface, a wood form 2 disposed in the clamping groove 3, and a cushion layer disposed on the surface of the wood form 2, and a surface of the wood form 2 close to concrete has the same shape as a designed surface.
Before construction, the wood pattern 2 is processed according to the design outline of the special-shaped section, the wood pattern 2 is installed in the clamping groove 3, the clamping groove 3 is installed at the designated position of a construction site, the cushion layer covers the surface of the wood pattern 2, and concrete is poured in the space formed by the wood pattern 2 in a surrounding mode. After waiting for the concrete to solidify the shaping and accomplish and accept, draw-in groove 3 and wooden model 2 can be pulled down.
Utilize draw-in groove 3 to provide the support to wooden model 2 to make wooden model 2 possess sufficient intensity in order to satisfy the requirement of concreting, avoid wooden model 2 to take place to warp and lead to construction quality to reduce under the effect of concrete pressure. The clamping grooves 3 are made of steel structures, the clamping grooves 3 with the special-shaped cross sections in different shapes can be repeatedly used during construction, and only different wood molds 2 need to be machined, so that the material recycling rate is improved. The wood pattern that trades down also can be used for other places that need the plank, avoids timber to cause the waste. Make 2 wooden formers and concrete break away from through setting up the bed course is convenient, avoid the concrete to pollute timber and lead to the variation of timber recycle effect.
Example 2:
on the basis of the above embodiment, in this embodiment, the cushion layer is made of an iron sheet. The cushion layer has certain strength to bear the pressure of concrete, and the wood pattern 2 is prevented from being polluted due to the damage of the cushion layer, or the wood pattern 2 is prevented from being difficult to separate from the concrete. The adoption of the iron sheet also facilitates the bending of the cushion layer into a required shape to meet the design requirement. The replaced cushion layer can be conveniently bent into other special-shaped cross section shapes by adopting corresponding equipment to achieve the aim of recycling, and material waste is avoided.
Example 3:
on the basis of the above embodiment, in this embodiment, a plurality of wood pattern supporting structures 6 for supporting the wood patterns 2 are disposed in the clamping grooves 3. Receive the influence of timber structure itself, the wooden model 2 that processes out probably can't laminate completely with draw-in groove 3, sets up wooden model bearing structure 6 in draw-in groove 3, can utilize wooden model bearing structure 6 to play the effect of support to wooden model 2 to the intensity and the rigidity of reinforcing wooden model 2 avoid wooden model 2 to bear the pressure of concrete and warp, damage.
The wood pattern 2, the clamping groove 3 and the wood pattern supporting structure 6 form a triangular structure, the stability of the wood pattern 2 is enhanced by utilizing the most stable principle of the triangular structure, and the wood pattern 2 is ensured to have enough strength.
In this embodiment, the wood pattern supporting structure 6 is made of profile steel, and the wood pattern supporting structure 6 is detachably connected with the clamping groove 3. Therefore, the wood pattern supporting structure 6 has enough strength and rigidity, and deformation or damage caused by the pressure of concrete borne by the wood pattern supporting structure 6 is avoided. The wood pattern supporting structure 6 and the clamping groove 3 are detachably connected, so that the wood pattern supporting structure 6 with different shapes and sizes can be conveniently replaced according to the wood patterns 2 with different shapes, and the position precision of the wood pattern 2 can meet the design requirement.
Example 4:
on the basis of the above embodiment, the side mold further includes a card slot support structure 5 for supporting the card slot 3. Utilize draw-in groove bearing structure 5 to support draw-in groove 3 from the one side that draw-in groove 3 kept away from the concrete, be favorable to improving the stability and the bearing capacity of draw-in groove 3 to avoid draw-in groove 3 to take place to warp under the effect of concrete pressure and lead to the position of wooden model 2 to change.
In this embodiment, the card slot supporting structure 5 is connected to the card slot 3 through a bolt 4. Therefore, the installation or the disassembly is convenient, and the construction efficiency is improved.
In this embodiment, other undescribed contents are the same as those in the above embodiment, and thus are not described again.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are included in the scope of the present invention.
