Technical Field

The utility model relates to a building templates supports technical field, specifically say that an adjustable spacing split bolt of taper sleeve pipe and shank of bolt combination.

Background

The traditional method of the split bolt technology for fixing the concrete template in the construction engineering is as follows: the two side templates are provided with holes, a round plastic sleeve is arranged in the holes through penetrating the two opposite template holes, a metal counter-pull bolt rod penetrates the round plastic sleeve, a transverse back ridge is arranged, and pipe clamps are sleeved at the two ends of the counter-pull bolt rod to tighten fastening nuts.

The traditional split bolt technology for fixing the concrete template has the following defects: 1. the round plastic sleeve is easy to crush when the concrete is vibrated, and the crushed concrete enters the round plastic sleeve to prevent the split bolt from being drawn out; 2. after concrete pouring is finished, the circular plastic sleeve cannot be taken out, and due to the smooth characteristic of the inner wall of the circular plastic sleeve, the hole is difficult to block, so that the hidden danger of rainwater leakage of the outer wall is caused; 3. the circular plastic sleeve and the split bolt are two components, so that the construction and installation are not simple and convenient; 4. because there is not stop device, concrete wall thickness relies on the cement mortar brace rod that sets up between the template of both sides and the operation workman screws up fastening nut's the feeling and controls, causes concrete wall to hang down straightness and the quality of roughness to be difficult to control, often surpasss standard regulation.

Chinese patent: patent numbers: ZL201820578390.4, utility model name: the integral tapered plastic-lined limiting split bolt has the advantages that 1, the production efficiency is low and the production cost is high due to the adoption of the injection molding process on the metal bolt rod; 2. because the middle conical lining plastic is firmly fixed on the metal bolt rod, the split bolt is not easy to maintain when part of the split bolt is damaged; 3. when the whole split bolt is scrapped, metal and plastic cannot be separately recycled; 4. the universality is not good, and the adjustment is not easy to realize when the wall bodies with different thicknesses are used.

The utility model has the following contents:

the utility model aims to overcome the defects of the prior art and provide an adjustable limit split bolt combined by a conical sleeve and a bolt rod; the problems that a split bolt circular plastic sleeve of a traditional fixed concrete template is easy to break, an outer wall is easy to leak rainwater and a plurality of members, construction, installation and dismantling are not simple and convenient, the verticality and the flatness of a concrete wall are difficult to control and the like are mainly solved; solving the problems of Chinese patent: patent numbers: the problem in ZL 201820578390.4.

The utility model provides a technical scheme is: the adjustable limiting split bolt with the combination of the conical sleeve and the bolt rod is characterized by comprising a metal bolt rod, the conical sleeve, a metal gasket and a nut with a pipe;

the middle position of the metal bolt rod is sleeved with a conical sleeve, metal gaskets are respectively arranged at two ends of the conical sleeve, and the outer sides of the metal gaskets are respectively provided with a pipe nut.

Furthermore, the conical sleeve is a hollow sleeve, the inner wall of the conical sleeve is provided with strip-shaped ribs, and the conical sleeve is conical in appearance.

Furthermore, the nut with the pipe is formed by fixing a locking nut and a limiting sleeve, and the length of the limiting sleeve is adjustable.

The utility model has the advantages that: 1. the disposable circular plastic sleeve is removed, which is beneficial to environmental protection; 2. the hidden danger that the round plastic sleeve is easy to break when the concrete is vibrated and the broken concrete enters the round plastic sleeve so that the split bolt cannot be drawn out is eliminated; 3. the hidden danger of outer wall leakage caused by the fact that the circular plastic sleeve cannot be taken out and is not easy to block is eliminated; 4. the construction and installation operations are simple and convenient, and the working efficiency is improved; 5. the stroke of the fastening nut is not controlled manually, and the fastening nut can be stopped after reaching the position under the action of the limiting sleeve, so that the thickness of the concrete can be accurately controlled, the position of the template can be controlled, and the verticality and the flatness of the concrete can be guaranteed; 6. the cost is reduced due to repeated use; 7. for Chinese patent: patent numbers: the problems in ZL 201820578930.4 are improved, the production process is simple, the production efficiency is improved, and the production cost is reduced; the maintenance is easy; the disassembly and the assembly are flexible, the length and the size are adjusted by using the limiting sleeve, and the universality is improved; can be recycled in a split way, and is beneficial to environmental protection.
