Description

Technical Field

[0001] The invention relates to the field of construction engineering, and more specifically to a prefabricated tooth joint of a structural column and a synchronous masonry construction method thereof. Background Art

[0002] In order to enhance the integrity and stability of the building, masonry brick walls need to be equipped with structural columns at the ends of straight sections without concrete wall columns, at the junction of the inner and outer walls of large rooms, at the corners of brick walls, on both sides of large openings, and in the middle of long walls. The structural columns constrain the masonry, giving it better bearing capacity and deformation capacity. Masonry structural columns need to be equipped with tooth joints as required, and the straight joints left in masonry projects do not meet the construction specifications. Therefore, at present, masonry structural columns are mostly constructed as secondary structures. After the masonry is completed, the wall is clamped on both sides and a chute is set on the top, and the concrete is poured manually. Secondary clamping and pouring can easily cause quality problems such as concrete expansion, leakage, and honeycomb holes, which reduces the surface flatness and visual quality of the wall. It is difficult to pour concrete manually. After the structural column is poured, the chute part needs to be chiseled and trimmed, which can easily increase the thickness of the plaster in the later stage and is not conducive to the promotion of the clear water wall process. The secondary pouring of structural columns not only has low overall construction quality, appearance and efficiency, but also increases the time interval between masonry and plastering, which is not conducive to construction period control. In view of the above problems, it is necessary to improve the existing structural column construction process. Summary of the invention

[0003] The object of the present invention is to provide a prefabricated tooth joint of a structural column and a synchronous masonry construction method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: comprising a structural column body, anchor bars, prefabricated tooth joints, blocks, tie bars, and filling materials, wherein the side surface of the structural column body is flat, and the structural column body itself does not include a tooth joint structure, anchor bars are arranged at vertical intervals on one or more sides of the structural column body, two anchor bars form a group and correspond to a tooth joint structure, and are arranged at vertical intervals, the outer distance between the two anchor bars is less than the height of the tooth joint structure, the prefabricated tooth joint is composed of concrete slabs on both sides and connecting bars, the height and width of the prefabricated tooth joint match the tooth joint structure, and the overall thickness formed between the concrete slabs matches the width of the blocks, two or more connecting steel bars form a group, each group of connecting steel bars corresponds to a prefabricated tooth joint, the connecting steel bars are arranged at vertical intervals, and both ends are bent and anchored in the concrete slabs on both sides of the prefabricated tooth joint, and the vertical outer distance of each group of the connecting steel bars is less than the vertical clear distance of each group of anchor bars.

[0005] One end of the anchor bar is anchored in the body of the structural column.

[0006] The bottom of the prefabricated tooth joint is placed on the wall blocks, one side of the prefabricated tooth joint in the width direction is in contact with the structural column body, and the other side is in contact with the masonry blocks.

[0007] The tie bars are arranged in the horizontal mortar joints between the blocks, and one end of the tie bars located within the height range of the prefabricated tooth joint is bent and placed between two concrete slabs of the prefabricated tooth joint for bending and anchoring.

[0008] The gaps formed by the two concrete slabs of the prefabricated tooth joint and the structural column body and the building blocks are filled and compacted by pouring filling materials.

[0009] The top of the structural column body is made of de-stoned concrete.

[0010] The connecting steel bars are constructed using stirrups.

The concrete is poured and vibrated to make it dense. The connecting steel bars are centered in the mold and pressed into the concrete to a certain depth. Support brackets are set to erect and fix the connecting steel bars. The concrete is finished to complete the first prefabrication.

[0016] S4: After the concrete reaches a certain strength, the formwork is removed, the mold is continued to be assembled, the concrete is poured and vibrated to make it dense, and then the support bracket is adjusted, the first batch of prefabricated connecting steel bars and concrete are turned over, the connecting steel bars are centered in the mold and pressed into the concrete to a certain depth, the concrete is finished, and the formwork is removed after the concrete reaches a certain strength.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] The present invention provides the following technical solution: a prefabricated tooth joint of a structural column, comprising a structural column body 1, anchoring bars 2, a prefabricated tooth joint 3, a building block 4, tie bars 5, and a filling material 6. The side of the structural column body 1 is flat, and the structural column body 1 itself does not include a tooth joint structure. Anchoring bars 2 are arranged at vertical intervals on one or more sides of the structural column body 1. Two anchoring bars 2 form a group and correspond to a tooth joint structure. The vertical intervals are arranged, and the outer distance between the two anchoring bars 2 is less than the height of the tooth joint structure. The prefabricated tooth joint 3 is formed by two sides. It is composed of a concrete slab 201 and connecting steel bars 202. The height and width of the prefabricated tooth joint 3 match the tooth joint structure. The overall thickness formed between the concrete slabs 201 matches the width of the block 4. Two or more connecting steel bars 202 form a group, and each group of connecting steel bars 202 corresponds to a prefabricated tooth joint 3. The connecting steel bars 202 are arranged at vertical intervals, and both ends are bent and anchored in the concrete slab 201 on both sides of the prefabricated tooth joint 3. The vertical outer distance of each group of connecting steel bars 202 is less than the vertical clear distance of each group of anchor bars 2.

[0031] Preferably, one end of the anchor bar 2 is anchored in the structural column body 1.

[0032] Preferably, the bottom of the precast tooth-like joint 3 is placed on the wall block 4. One side of the precast tooth-like joint 3 in the width direction is attached to the column body 1 of the construction column, and the other side is attached to the laid block 4.

[0033] Preferably, the tie bars 5 are arranged in the horizontal mortar joint between the blocks 4. One end of the tie bars 5 within the height range of the precast tooth-like joint 3 is bent and placed between the two concrete slabs 201 of the precast tooth-like joint 3 for bent anchoring.

[0034] Preferably, the voids formed by the two concrete slabs 201 of the precast tooth-like joint 3, the column body 1 of the construction column, and the block 4 are filled and compacted with a filling material.

[0035] Preferably, the top of the column body of the construction column is concrete 101 without stones.

[0036] Preferably, the connecting steel bars 202 adopt a stirrup structure.

[0037] Preferably, the filling material 6 adopts a special mortar with the same strength as that of the construction column.

[0038] Preferably, when the dimensions of the precast tooth-like joint 3 are relatively large, the number of each group of steel bars is increased for the anchoring bars 2 and the connecting steel bars 202 according to the actual situation.

[0039] Preferably, when the spacing of the tie bars 5 does not match the module of the precast tooth-like joint 3, one end of the tie bars 5 outside the structural height range of the tooth-like joint is anchored to the column body 1 of the construction column by post-inserted bars.

[0040] Preferably, the anchoring bars 2 are connected and anchored to the column body of the construction column by the method of post-inserted bars.

[0041] A synchronous masonry construction method for a precast tooth-like joint of a construction column includes the following steps:

[0042] S1: Reserve the bottom steel bars of the column body 1 of the construction column. The column body 1 of the construction column and the main building structure complete the steel bar binding and formwork pouring together. The column body 1 of the construction column is poured with beam and slab concrete, and when pouring to the top, a certain height is reserved and poured with concrete without stones.

[0043] S2: Before the construction of the masonry project, clarify the spacing and dimensions of the tooth-like joint structure of the construction column, determine the specifications, dimensions and quantities of the anchoring bars 2 and the precast tooth-like joint 3, and prefabricate the anchoring bars 2, the tie bars 5, and the connecting steel bars 202 in advance, and carry out the prefabrication of the precast tooth-like joint 3.

[0044] S3: The precast tooth-like joint 3 adopts a secondary prefabrication method. Set a certain number of molds according to the concrete slab size of the precast tooth-like joint 3, pour the concrete and vibrate it compactly, press the connecting steel bars 202 in the middle and align them with the molds and press them into the concrete to a certain depth, set up support brackets to erect and fix the connecting steel bars 202, and finish the surface treatment of the concrete to complete the first prefabrication.

[0045] S4: After the concrete reaches a certain strength, remove the formwork, continue to assemble the formwork and pour the concrete until it is vibrated compactly. Then adjust the support brackets, turn over the first batch of prefabricated connecting steel bars 202 and the concrete, center-align the connecting steel bars 202 and press them into the concrete to a certain depth, finish the surface of the concrete. After the concrete reaches a certain strength, remove the formwork, and complete the prefabrication of the precast tooth-like joints 3 through secondary prefabrication.

[0046] S5: Locate the tooth-like joint structure of the structural column body 1, and complete the planting and acceptance of the anchor bars 2 within the scope of the tooth-like joint structure and the tie bars outside the scope of the tooth-like joint structure.

[0047] S6: When constructing the masonry around the structural column, first construct the masonry below the tooth-like joint structure. Center-align the precast tooth-like joints 3 and the connecting steel bars 202 and pass them through the anchor bars 2 and press them tightly against the side of the structural column body. Place the precast tooth-like joints 3 on the top of the masonry and then bend the anchor bars 2. Adjust the outer sides of the concrete slabs 201 on both sides of the precast tooth-like joints 3 to align with the masonry wall surface, and continue to masonry along the side of the precast tooth-like joints 3 until it is flush with the top of the precast tooth-like joints 3. During this period, if there are wall tie bars, place the bent end inside the precast tooth-like joints 3, and lay the tie bars 5 on the top surface of the building blocks and then continue to masonry.

[0048] S7: Pour the prepared filling material into the precast tooth-like joints 3 and fill it tightly, then continue the synchronous masonry operation of the upper masonry building blocks and the precast tooth-like joints 3. Repeat this cycle until the masonry is completed. The structural column body constructed by this method can be formwork-supported and poured together with the floor concrete, which helps to improve the overall construction quality of the structural column body, avoid secondary manual pouring, and since the dimensions of the structural column body are relatively uniform, it is possible to better realize the standardization of the formwork.

[0049] The structure of the precast tooth-like joints 3 is simple. The secondary prefabrication method has a fast prefabrication speed and low cost, and the size of the precast tooth-like joints is small, and it can be made from on-site formwork waste, floor concrete surplus materials, and steel bar waste, which is energy-saving and environmentally friendly;

[0050] The concrete on both sides of the precast tooth-like joints 3 can be used as the formwork for the filling material 6. The pouring material inside the precast tooth-like joints 3 can be selected as the special cement mortar with optimized mix ratio or the same strength purchased for pouring. The pouring amount is small, which is convenient and fast;

[0051] Synchronous masonry of the precast tooth-like joints 3 of the structural column can make the wall surface form at one time, thus eliminating the time interval between the masonry project and the plastering project, speeding up the construction progress, and shortening the construction period;

[0052] The thickness of the precast tooth-like joints 3 is the same as that of the masonry. After the masonry project is completed, the surface is regular and has a high flatness, which helps to reduce the later plastering thickness and is conducive to the popularization of fair-faced walls.

[0053] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
