Description

Technical Field

[0001] The present application relates to the field of materials and equipment for formwork engineering in building construction, and in particular to a double-conical head concealed sleeve for wall beam surface formwork. Background Art

[0002] In the construction of concrete walls, it is necessary to first build a wall casting formwork, and then fix the outer side of the casting formwork through structures such as keels and back ribs to ensure the final concrete pouring effect. In order to ensure that the required spacing can be maintained between the parallel walls or beam surfaces, it is also necessary to set internal supports and plastic sleeves with screw holes between the wall formwork or beam side formwork on both sides. For example, most aluminum formworks in the existing technology use single conical tube concealed sleeves. Our company has applied for a patent for a concealed casing structure called "A size-adjustable, turnable, through-wall concealed pipe tensioning screw assembly (application number 202020164614.4)". However, this structure requires the casing, plug and two pads to be assembled before installation. Although it greatly enhances the versatility of the through-wall concealed pipe, due to the large number of parts and the large number required for a single construction, a lot of time needs to be spent on assembling parts before construction, which greatly affects the efficiency of construction. In addition, the material used is steel. Although the turnover number is sufficient, the production cost is high, and due to the small thermal expansion and contraction of steel, dismantling is time-consuming and labor-intensive. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the present application provides a double-conical head concealed sleeve for wall beam surface formwork, which can be quickly assembled and installed for use, and can also be quickly dismantled 24 to 48 hours after the concrete pouring is completed. Due to the large thermal expansion and contraction of plastic and the conical design of the product, the difficulty of dismantling is greatly reduced, thereby reducing the workload of construction personnel and improving the efficiency of actual construction. In addition, the diameters of both ends of the product are more than 40 mm, so that there is a larger contact area between it and the wall beam surface formwork, so that after the locking and reinforcement of the product is completed, the damage to the wall beam surface formwork is greatly reduced.

[0004] A double-conical head concealed sleeve for a wall beam surface formwork comprises a main sleeve made of plastic and a conical head made of plastic arranged on the top of the main sleeve; the bottom of the main sleeve is provided with a bottom sinking groove, and the top of the conical head is provided with a top sinking groove.

[0005] Preferably, the bottom sinking groove and the top sinking groove are both non-circular grooves.

[0006] Preferably, the bottom sinking groove and the top sinking groove are both quadrilateral grooves.

[0007] Furthermore, the main sleeve is composed of a sleeve body, a boss arranged on the top of the sleeve body and protruding outward, a conical foot arranged at the bottom of the sleeve body, and a sleeve hole that coincides with the central axis of the sleeve body and simultaneously passes through the boss, the sleeve body and the conical foot; the bottom sinking groove is arranged on the conical foot.

[0008] Preferably, the bottom of the boss is a frustum, and the top of the boss is a cone.

[0009] Preferably, the outer diameter of the top of the sleeve body is smaller than the outer diameter of the bottom thereof, and the outer diameter of the frustum is smaller than the outer diameter of the top of the sleeve body.

[0010] Furthermore, the conical head consists of a conical head body, an embedding groove arranged at the bottom of the conical head body, and a conical head hole that coincides with the central axis of the conical head body and passes through the conical head body; the top sinking groove is arranged at the top of the conical head body.

[0011] Preferably, the diameter of the sleeve hole is the same as the diameter of the tapered head hole.

[0012] Preferably, the embedding groove consists of a circular groove and a conical groove connected to the circular groove.

[0013] Preferably, the frustum matches the conical groove, the circular cone matches the circular groove, and the circular cone is fixed to the circular groove by interference fit.

[0014] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0015] The utility model can be quickly assembled and installed for use, and can also be quickly dismantled 24 to 48 hours after the concrete pouring is completed. Since the plastic has a large thermal expansion and contraction range and the tapered design of the product, the difficulty of dismantling is greatly reduced, thereby reducing the work intensity of the construction workers and improving the efficiency of the actual construction. In addition, the diameters of both ends of the product are more than 40 mm, so that there is a large contact area between it and the wall beam surface template, so that after the locking and reinforcement of the product is completed, the top support damage to the wall beam surface template is greatly reduced.

[0030] Example 1

[0031] like Figure 1-5 As shown, a double-conical head concealed sleeve for a wall beam surface formwork includes a main sleeve 100 made of plastic, and a conical head 200 made of plastic arranged on the top of the main sleeve 100; the bottom of the main sleeve 100 is provided with a bottom sinking groove 104, and the top of the conical head 200 is provided with a top sinking groove 203.

[0032] The bottom sinking groove 104 and the top sinking groove 203 are both non-circular grooves.

[0033] The function of the bottom sinking groove and the top sinking groove is to facilitate the construction workers to remove the main sleeve and the conical head by rotation; first, it is necessary to prepare in advance an L-shaped rod with an embedded block that matches the shape of the bottom sinking groove and the top sinking groove, and then the construction workers embed the embedded block into the bottom sinking groove and the top sinking groove, and rotate the L-shaped rod to drive the bottom sinking groove and the top sinking groove to rotate. Finally, during the rotation process, the bottom sinking groove and the top sinking groove slowly withdraw from the wall.

[0034] The bottom sinking groove 104 and the top sinking groove 203 are both quadrilateral grooves.

[0035] Considering the production process and ease of use, the preferred shape of the bottom sinking trough and the top sinking trough is a quadrilateral trough.

[0036] The main sleeve 100 consists of a sleeve body 101, a boss 102 arranged on the top of the sleeve body 101 and protruding outward, a tapered foot 103 arranged at the bottom of the sleeve body 101, and a sleeve hole 105 that coincides with the central axis of the sleeve body 101 and simultaneously passes through the boss 102, the sleeve body 101 and the tapered foot 103; the bottom sinking groove 104 is arranged on the tapered foot 103.

[0037] The bottom of the boss 102 is a frustum 106 , and the top of the boss 102 is a truncated cone 107 .

[0038] The outer diameter of the top of the sleeve body 101 is smaller than the outer diameter of the bottom thereof, and the outer diameter of the frustum 106 is smaller than the outer diameter of the top of the sleeve body 101 .

[0039] The conical head 200 consists of a conical head body 201, an embedding groove 202 arranged at the bottom of the conical head body 201, and a conical head hole 204 that coincides with the central axis of the conical head body 201 and passes through the conical head body 201; the top sinking groove 203 is arranged at the top of the conical head body 201.

[0040] The diameter of the sleeve hole 105 is the same as the diameter of the tapered head hole 204 .

[0041] The embedding groove 202 is composed of a circular groove 206 and a tapered groove 205 communicating with the circular groove 206 .

[0042] The frustum 107 matches the conical groove 205 , the circular table 106 matches the circular groove 206 , and the circular table 106 is fixed on the circular groove 206 by interference fit.

[0043] The purpose of setting the cone and the cone groove is to reduce the difficulty of aligning the boss and the embedded groove so that the boss can be quickly inserted into the embedded groove. The purpose of setting the round cone and the round groove is to enable the boss and the embedded groove to have an interference fit, thereby preventing the boss and the embedded groove from falling off when the product is used.

[0044] It should be noted that the bottom diameter of the conical foot and the top diameter of the conical head should be greater than or equal to the maximum diameter of the pad in the patent "A wall-penetrating concealed pipe tensioning screw assembly with adjustable size" described in the background technology, that is, the bottom diameter of the conical foot and the top diameter of the conical head should be greater than 40 mm.

[0045] Wall formwork is composed of several assembled wall modules, so concealed tubing is required to abut the edges of the modules to prevent deformation. At the corners where four modules meet, concealed tubing must abut the edges of up to four modules simultaneously. To reduce the force per unit area at the corners of individual modules and prevent fracture due to excessive force, the minimum outer diameters of the tapered feet and heads are specified. This maximizes the contact area between the product and the module, thus improving its performance.

[0046] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0047] In addition, the above-mentioned specific embodiments are merely illustrative. Those skilled in the art may devise various solutions based on the disclosure of this utility model, and such solutions fall within the scope of disclosure and the scope of protection of this utility model. Those skilled in the art should understand that the specification and drawings of this utility model are illustrative and do not constitute limitations of the claims. The scope of protection of this utility model is defined by the claims and their equivalents.
