Description
Technical field
The utility model relates to the concrete construction formwork field, is specially a kind of detachable waterproof Screw arbor with nut at both-ends.
Background technology
In outer wall of basement structurally waterproof concrete construction, when using common barrier properties template split bolt, behind stripping, cut wood block filler, cut off the screw rod that leaks outside, adopt waterproofing mortar to fill up spiro keyhole position.When requiring the clear-water concrete finishing effect for the outer wall of basement medial surface, traditional barrier properties template split bolt job practices has following limitation:
1) when concreting along the screw rod spillage that outwards seeps water, cause the bolt hole surrounded surface to produce pitted skin, color is inconsistent.
2) cut wood block filler after, adopt polymer mortar shutoff split bolt hole, form on the metope on " patch ", its presentation quality does not far reach the requirement of clear-water concrete facing.
Summary of the invention
The purpose of the utility model is to provide a kind of outside seepage phenomenon around the bolt hole when stopping to water, and does not destroy the detachable leakproof Screw arbor with nut at both-ends device that is used for the clear-water concrete cast of clear-water concrete facing requirement.
In order to achieve the above object, the utility model is achieved in that
A kind of detachable leakproof Screw arbor with nut at both-ends device; It comprises chevron card, the first harness cord screw rod, the first end hold-doun nut that is connected with the first harness cord screw rod end thread, be symmetrically arranged in two first seal rings on the first harness cord screw rod, be placed on the first harness cord screw rod and be positioned at first cushion block of first seal ring, one end; Also comprise the second harness cord screw rod, be located at the second end hold-doun nut of the second harness cord screw rod, one end, truncated cone plug, connecting bolt and plug set bolt; The second harness cord screw rod is connected with the first harness cord screw rod through connecting bolt, and the truncated cone plug is placed on the second harness cord screw rod and by the plug set bolt and fixes; The chevron card is located at the first harness cord screw rod, the second harness cord screw rod two ends respectively and is fixed by first end hold-doun nut, the second end hold-doun nut respectively.
Described detachable leakproof Screw arbor with nut at both-ends device is between its chevron card and the end set bolt, all be furnished with waterproof washer between truncated cone plug and the plug set bolt.
The utility model adopts above-mentioned design, and the phenomenon of outside seepage around the bolt hole in the time of can effectively preventing to water clear-water concrete can improve the also construction quality requirement of clear-water concrete facing simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below further specify the utility model through specific embodiment.
As shown in Figure 1; A kind of detachable leakproof Screw arbor with nut at both-ends device; It comprises chevron card 7, the first harness cord screw rod 1, the first end hold-doun nut 8 that is connected with the first harness cord screw rod, 1 end thread, be arranged in two first seal rings 3 on the first harness cord screw rod 1, be placed on the first harness cord screw rod 1 and be positioned at the cushion block 2 of first seal ring, 3 one ends; Also comprise the second harness cord screw rod 6, be located at the second end hold-doun nut 8 of the second harness cord screw rod, 6 one ends, truncated cone plug 5, connecting bolt 4 and plug hold-doun nut 9; The second harness cord screw rod 6 is connected with the first harness cord screw rod 1 through connecting bolt 4, and truncated cone plug 5 is placed on the second harness cord screw rod 6 and by plug hold-doun nut 9 and fixes; Chevron card 7 is located at the first harness cord screw rod 1 and the second harness cord screw rod, 6 two ends respectively and is fixed by first end hold-doun nut 8, the second end hold-doun nut 10 respectively.
Described detachable leakproof Screw arbor with nut at both-ends device, its chevron card 7 and first end hold-doun nut 8, the second end are fixedly between the spiral shell cat 10, all be furnished with waterproof washer 11 between truncated cone plug 5 and the plug hold-doun nut 9.
Use the step of this Screw arbor with nut at both-ends device:
Step 1: sealing steel loop balanced welding is connected on the first harness cord screw rod 1, cushion block 2 is placed on the first harness cord screw rod 1 and near the end face of the first sealing steel loop 3, connecting bolt 4 is threaded with the first harness cord screw rod 1 and full weld is fixed.
Step 2: truncated cone plug 5 is placed on the second harness cord screw rod 6, the second harness cord screw rod 6 is threaded with connecting bolt 4.
Step 3: be provided with at the two ends of the first harness cord screw rod, 1, the second harness cord screw rod 6 that template back of the body wood is stupefied, plain form and fixing with first end hold-doun nut 8, the second end hold-doun nut 10,7 cooperations of chevron card respectively.
Step 4: regulate the verticality and the flatness of plain form and finally plain form is got final product near truncated cone plug 5 and cushion block 2 through chevron card 7, first end hold-doun nut 8, the second end hold-doun nut 10.
The advantage of this Screw arbor with nut at both-ends device is:
The second harness cord screw rod 6 forms one group of split bolt with interior plug hold-doun nut 9 and the outer end hold-doun nut of self finish template of plain form for plain form; Truncated cone-shaped taper plug 5 and plain form are compressed; Prevent that concrete slurry and water are lost in the hole of taper plug in the process of building; Effectively reduce the loss of moisture and slurry in the concrete, guaranteed the decoration sense matter of the indwelling spiro keyhole position of finishing effect.Simultaneously; Play the gib headed bolt effect in the similar steel form hardened system, can adjust the planeness of plain form, can block template be spliced into big sheet template and lift; Realize the template construction that becomes more meticulous; Effectively the faulting of slab ends phenomenon is tight with the assurance form joint in the plane for the control template seam, has improved clear-water concrete finishing effect quality greatly, stops the concrete surface quality common fault that produces because of the template system reason.
Therefore, in sum, the phenomenon of outside seepage around bolt hole when the described detachable waterproof Screw arbor with nut at both-ends of the utility model can effectively prevent to water clear-water concrete can improve the also construction quality requirement of clear-water concrete facing simultaneously.
