In the figure, 100 is installed with a reserved device, 1 reserved rod, 11 penetrating part, 111 external thread, 12 convex part, 13 nut, 2 sleeve, 3 template and 4 superimposed plates.
Detailed Description
The utility model is further described with reference to the following figures and specific examples.
Referring to fig. 1 to 4, a prefabricated plywood laying position lower bushing installation reservation device 100 includes a reservation rod 1 and a bushing 2; the reserved rod 1 comprises a penetrating part 11 and a convex part 12, one end of the penetrating part 11 is installed on the template 3, and the other end of the penetrating part 11 penetrates to the inner side of the template 3 and is inserted into the sleeve 2; a boss 12 is provided on the other end of the through-portion 11, a positioning hole (not shown, provided at a position corresponding to the boss 12) is formed at the top of the sleeve 2, and the boss 12 can be inserted into the positioning hole so that the sleeve 2 is placed on the through-portion 11 and erected between the side forms 3. Through the setting of portion 11 that runs through can be when 3 prop up of template synchronous mounting sleeve pipe 2, be located the below that superimposed sheet 4 shelved the position to avoided the unable location of sleeve pipe 2 and falling and the problem that 4 tip of superimposed sheet need the manual work to chisel off pouring quality of wall body at the pouring in-process, and not influenced.
The surface of the through part 11 is formed with an external thread 111, and a screw hole (not shown in the figure and arranged corresponding to the installation elevation position of the sleeve 2) matched with the external thread 111 is reserved on the template 3, so that the through part 11 can be screwed on the template 3 and locked by a nut 13. Under the meshing action of the threads, the through part 11 is reliably connected with the template 3, so that the through part 11 is ensured to reliably support the sleeve 2, and meanwhile, the horizontal position adjustment of the through part 11 can be realized under the screwing-in and screwing-out action of the threads, so that the insertion between the protruding part 12 and the positioning hole is ensured. The reserved rod 1 can also be pushed to realize the position adjustment of the penetrating part 11 by adopting hydraulic pressure, air pressure and other modes, and the detailed description is omitted here.
When the sleeve 2 is placed on the penetrating part 11, the top surface of the protruding part 12 is flush with the top surface of the sleeve 2, so that the effect that the protruding part 12 affects the concrete pouring quality of a wall body can be avoided, and the protruding part 12 and the sleeve 2 can be detached and separated conveniently.
Because the wall thickness of the sleeve 2 is small, in order to improve the connection reliability between the sleeve 2 and the through part 11 and prevent the sleeve 2 from rotating in the pouring process, when the sleeve 2 is placed on the through part 11, the top surface of the convex part 12 is slightly higher than the upper surface of the sleeve 2, and the sleeve 2 can be effectively positioned.
Preferably, the height of the protrusion 12 extending above the top surface of the sleeve 2 is not more than 4mm, i.e. the height of the protrusion 12 is not more than 4mm greater than the wall thickness of the sleeve 2. In order to reduce the influence of the portion of the protruding portion 12 extending above the top surface of the sleeve 2 on the concrete placing quality of the wall body and to make the reserved rod 1 detachable from the sleeve 2, the protruding length of the protruding portion 12 should be as small as possible while ensuring the connection reliability between the penetrating portion 11 and the sleeve 2.
Referring to fig. 1 and 2, the construction method of the installation reservation device 100 of the present invention is:
step 1: according to the pre-buried height of sleeve pipe 2 in the design of wall body, correspond the screw in advance of sleeve pipe 2's elevation department on the template 3 of wall body, will reserve the through part 11 of pole 1 and connect soon on template 3 through screw thread 111 through the external screw thread to fix a position through nut 13 locking.
The setting number of the reserved rods 1 can be adjusted according to the information such as the thickness of the wall body and the weight of the sleeve 2. For example: when the sleeve 2 is a PVC pipe with a short length, a reserved rod 1 can be arranged on the template 3 on one side; when sleeve pipe 2 adopted the great steel pipe of quality or the longer pipeline of length, can all set up one on both sides template 3 and reserve pole 1, set up more many as required even and reserve pole 1 to ensure the effective support to sleeve pipe 2, sleeve pipe 2's stability when guaranteeing concrete placement.
In order to improve the installation stability of the through part 11, screw holes can be reserved on the template 3 and a cushion block fixed on the outer side of the template 3, the length of the fixed segment of the through part 11 is increased, and the through part 11 can provide more reliable supporting force for the sleeve 2.
Step 2: according to the number of the reserved rods 1 and the distance between the convex parts 12 and the inner walls of the templates 3, positioning holes are reserved at the corresponding positions of one end or two ends of the sleeve 2, so that when the sleeve 2 is horizontally erected between the templates 3 on two sides through the reserved rods 1, the reserved rods 1 are inserted into the sleeve 2, and the convex parts 12 can be just inserted into the positioning holes.
And step 3: erecting formworks 3 on two sides of the wall body, and synchronously installing the sleeve 2 when the formworks 3 are erected. The two ends of the sleeve 2 are attached between the two side templates 3, the protruding portions 12 are inserted into the positioning holes, the sleeve 2 is placed on the penetrating portions 11 under the action of gravity, and the sleeve 2 is stably and horizontally erected between the two side templates 3.
And 4, step 4: and (5) pouring concrete of the wall body. Because there is certain clearance between locating hole and bellying 12, concrete grout probably fills in this clearance when pouring, under concrete grout's adhesive action, can effectively avoid reserving the relative motion between pole 1 and the sleeve pipe 2, guarantee the stability of sleeve pipe 2, also guaranteed the quality of pouring of wall body. When pouring, because reserve pole 1 and be located sleeve pipe 2, do not influence the pouring quality of concrete, and easily dismantle.
And 5: when the form is removed, the concrete does not reach the designed strength, and the outer end of the reserved rod 1 is lightly knocked to separate the bulge 12 from the concrete in the gap. Because a certain gap is usually left between the bottom of the template 3 and the lower laminated slab, when the template is disassembled, the template 3 can be slightly moved downwards to separate the convex part 12 from the sleeve 2, and finally, the installation reservation device 100 and the template 3 are synchronously disassembled. The installation reservation device 100 can be detached from the formwork 3 and used in turn in the pre-burying construction of other casings 2.
The present invention is not limited to the above embodiments, and any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
