TECHNICAL FIELD

[0001] The utility model belongs to building manufacturing equipment technical field, more specifically, it relates to a simple and practical bolt group post -field assembly positioning frock. BACKGROUND

[0002] With the development of science and technology and industrialization, more and more various assembly type structures and steel structure workshops such as chemical plant, machinery plant, power station, power transmission and transformation station are used, compared with traditional building, the workshop foundation and equipment foundation of this kind of building are connected with main structure and equipment by pre-embedded bolt, have construction flow, factory, production efficiency is high, precision is high, connection is reliable, easy to maintain and replace and many advantages.But the precision of bolt pre-embedding affects the installation precision of subsequent structure or equipment, and further affects the stress of structure and normal operation of equipment.

[0003] At present, domestic chemical plant equipment foundation high-precision bolt pre-embedding usually has two kinds: one is to adopt tool type fixture to be temporarily fixed, then to be welded on equipment foundation steel reinforcement framework, then to remove temporary fixture, and to measure and check in whole process to ensure that the precision meets the requirements during pre-embedding process, another kind is that there is bolt positioning steel plate in design, bolt and positioning steel plate are connected and fixed during construction, then the whole is hoisted to equipment foundation, and is welded and fixed through anchor reinforcement on positioning steel plate and equipment foundation steel reinforcement framework.The former has low work efficiency, and consumes more manpower, and the latter wastes positioning steel plate and anchor reinforcement additionally. SUMMARY

[0004] The utility model provides a simple and practical bolt group post -field assembly positioning frock, solves the problem of low work efficiency, large manpower consumption, additional waste of positioning steel plate and anchor reinforcement of bolt group pre-embedding, and simultaneously solves the problems of temporary fixation and positioning during bolt group post -field assembly.

[0005] To solve the above technical problems, the technical scheme adopted by the utility model is:

[0006] A simple and practical bolt group post -field assembly positioning frock, including hole panel, support framework,

[0007] The hole panel is two pieces of upper and lower, and is connected into a whole through the support framework, to ensure the stability and non-deformation of the frock.

[0008] The hole panel is provided with a plurality of reserved holes corresponding to the bolt group, and the reserved holes are matched with the diameter of the bolt group.

[0009] The size of the hole panel is matched with the plane size of the pre-embedded bolt group.

[0010] Preferably, the hole panel is made of plywood.

[0011] Preferably, the supporting frame is made of square timber.

[0012] The beneficial effects of adopting the above technical solution are as follows:

[0013] 1) This utility model realizes the post-construction assembly of bolt groups, which makes the bolt group assembly parallel to the processes of foundation pit excavation, cushion layer pouring and foundation steel reinforcement cage installation, thereby shortening the total time of bolt pre-embedding and improving work efficiency.

[0014] 2) This utility model has a simple and reliable structure, readily available materials, low cost, convenient processing and operation, and strong feasibility and applicability.

[0015] 3) This utility model has a compact structure, light weight, convenient transfer, recyclability, high turnover rate, high efficiency, high precision, high work efficiency, and no pollution.

[0016] 4) This utility model requires no special maintenance in daily life, has low maintenance costs, and high overall benefits. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] like Figures 1-2 As shown, a simple and practical bolt assembly positioning fixture includes a perforated panel 1 and a support frame 2.

[0022] The reserved hole 3 is located on the perforated panel 1.

[0023] The perforated panel 1 consists of two pieces, upper and lower, which are connected as a whole by the supporting frame 2 to ensure the stability and non-deformation of the fixture.

[0024] The hole panel 1 is provided with a plurality of reserved holes 3 corresponding to bolt groups, and the reserved holes 3 are matched with the diameter of the bolt groups, and when the holes are punched (the reserved holes 3 are opened), the holes are punched on the hole panel 1 according to the position parameters (distance, relative position) of each bolt in the bolt group and the diameter of the bolt in a 1:1 manner, and the punching precision of the hole panel 1 meets the installation precision standard of the bolt group.

[0025] The size of the hole panel 1 is matched with the size of the embedded bolt group, so that all the bolts of the bolt group can be arranged on the hole panel 1. Figure 1

[0026] When the upper and lower panels 1 are connected with the support framework 2, the upper and lower holes are one-to-one corresponding and the hole centers must be coincided.

[0027] Specifically, two same fixtures are used for temporary fixing of each bolt group (the bolt group is sleeved on the fixture).

[0028] Specifically, different bolt groups (different number of bolts, different diameter, different distance, different arrangement shape) can be individually manufactured according to actual needs, so as to improve the adaptation range.

[0029] The construction and installation steps of the utility model are as follows:

[0030] Step S1: first, different fixture sizes are designed according to different bolt groups in the construction drawing, so that each type of bolt group can be matched with the corresponding fixture.

[0031] Step S2: the reserved holes 3 are opened on the hole panel 1 according to the position parameters (distance, relative position) of each bolt in the corresponding bolt group and the diameter of the bolt in a 1:1 manner.

[0032] Step S3: first, take a hole panel 1, and paste or nail the support framework 2 on it to make it into a whole.

[0033] Step S4: take another hole panel 1, check the position of the reserved hole 3, and make it one-to-one corresponding with the reserved hole 3 of the upper hole panel 1 and the hole center completely coincides, and then paste or nail it on the upper surface of the support framework 2, so that the three form a stable and firm whole.

[0034] Step S5: according to the relative position and height difference on the bolt embedding drawing, the corresponding bolts are sleeved on the corresponding two fixtures, the upper and lower surfaces of the fixture close to the free end of the bolt are fixed by the nut on the bolt, and the fixture close to the fixed end of the bolt can move along the bolt.

[0035] ​Step S6: After checking the relative position of the bolt, the relative height difference of the free end of the bolt, the perpendicularity of the tool and the bolt, the same group of embedded bolts is welded and fixed into a whole from the anchoring end to the free end of the bolt by using the leftovers (short steel bars) of the steel bar field.

[0036] Step S7: After the welding to the bolt group is stable and does not deform, the welding is stopped and the tool is removed from the free end of the bolt.

[0037] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
