Description

Combination sealing up screw through walls

Technical field

This practicality is involved in building operations, underground and on the ground mine dam, post, beam, the oblique stable and combination sealing up screw through walls reinforced of form work engineerings such as roofing.

Background technology

In building operations, waterproofing is a huge object of construction production beyond doubt, during the underground outer shear wall of concrete pouring; The normal whole screw rod through walls that has the sealing metallic gasket that adopt set up and support shuttering, in the present construction work shear wall wooden form mounting technique, uses whole screw rod that the inside and outside wooden form of shear wall is installed; And then add the soldering iron sheet at screw rod middle part and stop outdoor water in the screw rod inlet chamber; Reaching in the fixing inside and outside wooden form of shear wall again can be up to the effect of sealing, but owing to use one whole screw rod, length is longer; The wooden form splicing is big and heavy; Be not easy stripping from long bolt during form removal, and behind the stripping, stay outside on the wall unnecessary screw rod also will slice off.Its shortcoming is structure more complicated when screw rod is installed, and screw rod is disposable use, and waste is big; Form removal quite bothers, and in addition, the unnecessary screw rod that stretches out surface of wall need cut off with oxygen-acetylene; Doing like this when taking a lot of work very much, also is to cost waste, strengthens the engineering construction cost.

The utility model content

The utility model purpose provides a kind of simple in structure, and the folding dress is convenient, economizes on resources, and improves the material number of turnover, can improve construction technology, improves the workmanship of body of wall, and stagnant water effect better makes up sealing up screw.

For realizing above-mentioned purpose, the utility model can be taked following technical scheme:

The described combination sealing up screw through walls of the utility model; Be the split combining structure, comprise getting in the shear wall fully and fullly in the centre position being welded with the inner screw of sealing iron sheet and passing wooden form and the fixing external screw rod of wooden form; The sealing iron sheet is a galvanized sheet iron in the middle of the said inner screw; Said inner screw all is welded with fixedly hex nut near the outer two ends of wall, and the said fixedly hex nut outside is welded with the zinc-plated location of template iron plate, forms two antiprimings between said location iron sheet and sealing iron sheet; The corresponding fixedly hex nut screw of said location iron sheet central point; Said external screw rod has additional steel pipe mountain type card when fixing wooden form, the steel pipe that said steel pipe mountain type card centre bore passes external screw rod and combines two horizontal positioned is fixing wooden form together, and is locked with movable hex nut.

Preferably, said external screw rod shaft evenly is covered with screw thread, and screw thread is the compact screw thread, can improve the sealing function.

Preferably, said external screw rod outermost end is provided with the hexagonal screw rod of 5 centimeter length, reverses with spanner when making things convenient for external screw rod to connect with inner screw to install and fix and dismantle.

Preferably; Said steel pipe mountain type card up and down two ends is designed to the hook arc shape, and two inboard centers are provided with in one and press arc up and down, presses arc to be used for pressing the firm steel pipe of deciding two horizontal positioned in said; Can effectively strengthen the fixed effect that wooden form is installed, improve stability.

Preferably, said inner screw and external screw rod thread connection place have additional metallic gasket, and be tightr after making external screw rod and inner screw connecting, and is not prone to loosening.

Preferably, said inner screw is the circular section screw rod with external screw rod, and the big I of screw rod is decided according to the engineering size.

The beneficial effect that the utility model adopts above scheme to produce is: said combination sealing up screw through walls, adopt the split combining structure, and the folding dress is convenient during use; Convenient construction, the life cycle number of times of raising material economizes on resources; Reduce labour intensity, save more human resources, the sealing iron sheet is a galvanized iron sheet in the middle of the said inner screw; Fixedly the hex nut outside is welded with the zinc-plated location of Template Location iron plate, forms two antiprimings between said location iron sheet and sealing iron sheet, can more effectively improve stagnant water effect; Improve the engineering total quality, said iron plate adopts zinc-plating material can play anti-oxidation effect, can improve the iron sheet quality; Thereby raising stagnant water effect, and can improve service life and the service property (quality) of inner screw in mast, said external screw rod have additional steel pipe mountain type card when fixing plank sheathing; Said steel pipe mountain type card is in conjunction with two steel pipes of horizontal positioned and turn round traveling nut fixing plank sheathing jointly, can effectively strengthen the fixed effect that plank sheathing is installed, and improves stability; Make the plank sheathing convenient disassembly, the agents enhance overall construction quality reduces plank sheathing and in unloading process, damages body of wall.
