Abstract
The utility model discloses a waterproof concrete shear wall tool type water-stopping split bolt which belongs to the field of construction technology, and particularly relates to a bolt used for construction of underground water concrete structures and wall pouring formworks. The split bolt comprises a screw (1) and a water-stopping plate (2), wherein the water-stopping plate (2) is fixedly arranged in the middle of the screw (1). The split bolt is characterized in that external threads are arranged at two ends of the screw (1), and sleeves (3) with internal threads are symmetrically arranged at two ends of the screw (1) by the external threads. The split bolt has the advantages of being simple and convenient to install and demount, repeatable in use, material-saving, simple in production and the like, improves the construction efficiency and reduces the construction cost.
Description
Technical field
Waterproof concrete shear wall tool-type water stopping type split bolt belongs to the realm of building construction, is specifically related to a kind ofly be used for the construction of underground waterproof concrete structure and wall formwork for placing and use bolt.
Background technology
At present, in the engineering construction of concrete shear wall structure, outer wall of basement is structure from waterproof, when construction; For preventing the body of wall mould that rises, need corresponding sealing split bolt is set, and most of sealing Screw arbor with nut at both-ends mostly adopts monolithic sealing Screw arbor with nut at both-ends structure that template is reinforced according to thickness of wall body, promptly sealing up screw be by an elongated round steel through two ends mantle fiber process; And in the middle of screw rod, add weldering sealing steel disc, at the monolithic sealing split bolt of welding Template Location rod member in the screw thread certain distance of two ends, this kind monolithic sealing split bolt not only processing method expense of taking a lot of work is expected; And it is in use, need earlier screw rod to be passed template, and fastening at template external application pad, nut; Stripping after construction is accomplished will expose unnecessary screw rod excision, and smear rustproof paint at screw end head; Need electrogas welding and scaffold work high above the ground compounding practice when the bottom height is bigger during dismounting, danger is bigger, the expense of taking a lot of work material; The construction peace is torn inconvenience open, and efficient is low, and the impression effect is relatively poor.Meanwhile; Because monolithic sealing Screw arbor with nut at both-ends is behind stripping, inside and outside of concrete all leaves the unnecessary screw rod of an end, and cutting back screw end head stagnant water effect can't reliably be guaranteed; And cutting back screw end head is in underground or the wet environment for a long time; Corrosion can take place in the steel screw rod, even the corrosion of screw rod expansion meeting destruction concrete structure, and water can get into concrete structure inside along the slit that the screw rod corrosion produces; Not only destroy the globality of structure, also influenced the normal function of use of structure simultaneously.
Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency of prior art, a kind of reusable, energy conservation, easy installation and removal waterproof concrete shear wall tool-type water stopping type split bolt flexibly is provided.
The utility model solves the technical scheme that its technical problem adopted: this waterproof concrete shear wall tool-type water stopping type split bolt; Comprise screw rod and sealing sheet; Screw rod middle part fixed installation sealing sheet; It is characterized in that: said screw rod two ends are provided with external screw thread, and the internal thread sleeve is installed through the external screw thread symmetry in the screw rod two ends.The part that screw rod is had more changes telescopic connection into, can realize that the turnover that repeats of secure component is used, and saves material, and reduces construction cost.
Described internal thread sleeve one end is weldingly fixed on the external screw rod, and inside is provided with internal thread, outside suit taper block, and the external screw rod other end is provided with external screw thread.The internal thread sleeve passes through the thread connection screw rod, installation, convenient disassembly, flexible, time saving and energy saving, construction rapid and convenient.
The internal thread of described internal thread sleeve and the external screw thread of screw rod are complementary, and the end border that the internal thread sleeve connects with screw rod is provided with catch.The thickness of body of wall can be effectively controlled in the setting of catch, eliminates the body of wall middle part that traditional handicraft exists, because of reinforcing the common quality defect of the reduced cross-sectional that excessively causes.
Compared with prior art, the beneficial effect that the utility model had is:
1, simple in structure, easy to make; Screw rod and internal thread sleeve freely long and short can use the template of unlike material and the wallboard of different-thickness, and material is common; Cost is lower; Obviously practiced thrift construction cost, applicable to Industrial and Civil Engineering concrete beam, post, shear wall form work engineerings such as (including the concrete wall of waterproof requirement), the scope of application is wider;
2, installing/dismounting is flexible, combines with template closely, is easy to save labor from taking out within the walls, has accelerated the installation of split bolt and has removed work efficiency, has obviously improved efficiency of construction, and the construction rapid and convenient has improved workmanship when reducing labour intensity;
3, can reuse, realize the recycling of split bolt and fastening assembly, when improving work efficiency, reduce the consumption of non-ferrous metal, practice thrift resource, improve utilization rate of raw materials, and accurate positioning, fixation can be guaranteed workmanship;
4, effectively overcome the phenomenon that thread alternating, slide fastener appear in traditional split bolt easily, caused the defective of the mould that expands when having avoided concreting, obviously improved the tensile strength of concrete blinding split bolt, further guarantee workmanship.
