Description
Technical Field
The invention relates to the technical field of concrete construction, in particular to a complete construction method for a wallboard embedded part.
Background
With the continuous improvement of the whole level of national economy and the continuous acceleration of the development speed of industrial buildings in China, the environmental requirements of people on production operation are higher and higher, and pipelines and cable bridge supports which are used for production are inevitably arranged along the inner wall of a building in order to meet the production and installation requirements of various major and provide a larger working face. The installation appearance quality of the pipeline and the bridge frame can be horizontal, flat and vertical, and the acceptance requirement is met. The support fixed to the side wall plays a decisive role. Most of the fixing frames are welded with embedded parts on the side walls, so that the installation positions of the embedded parts are accurate, and the surfaces of the embedded parts are flush with the concrete surface. The installation quality of the pipeline and the bridge can be greatly improved, the construction period is effectively shortened, and the cost is saved.
The common installation method of the wallboard embedded part at the present stage comprises the following steps: after the steel bars are bound, marking the central line of the wallboard in the longitudinal direction and the height direction by using a construction line according to the drawing size, then arranging the single embedded parts according to the drawing size according to the central line, and finally binding the embedded part anchor flukes with the horizontally distributed steel bars of the wallboard. Because the anchor fluke ligature of embedded part is on horizontal distribution muscle, very easily receives the influence of reinforcing bar, at the concrete placement in-process, the vibrating spear touches the reinforcing bar and slightly disturbs and will cause the embedded part sunken, or the skew. The method has high installation speed, but has poor accuracy and large influence on subsequent construction.
The further installation method is as follows: before the embedded part is installed, the embedded part anchor fluke is welded to be equal to the wall thickness, a hole is formed in the center of the embedded part, a small section of counter-pulling screw rod penetrates out of the embedded part hole in advance, a stop block is arranged at the end of the counter-pulling screw rod, the rear part of the embedded part is pulled, and meanwhile later fastening is facilitated. And after positioning and paying off, jacking the embedded anchor fluke to the edge of the template according to the requirements of a drawing, and then sealing the template. And finally, fixing the pre-penetrated counter-pulling screw rod by using the back edge. The installation principle is as follows: the embedded anchor fluke is equal to the wall thickness, so that the inner side of the embedded surface template is ensured to be tightly attached, and the embedded surface template is further reinforced through a reserved counter-pulling screw rod, so that the embedded surface is flush with the concrete side wall surface after the template is removed, and the embedded surface is prevented from sinking. This type of installation adds a significant amount of welding work when the number of wall panel inlays is high. Therefore, the flatness of the embedded part can be well controlled by using the method, but the embedded part has low positioning precision, time and labor are wasted, and extra cost is generated. It is therefore not suitable for cases where the number of inserts is high.
Disclosure of Invention
The invention aims to overcome the defects and provide a construction method which can still ensure the one-time installation yield of embedded parts even under the condition of large-scale embedded part operation.
In order to achieve the above object, the present invention is realized by:
a complete set of construction method for embedded parts of wall boards comprises
Step 1: determining a horizontal central line of the embedded part along the height direction according to the drawing size, and marking the horizontal central line by using a construction line;
step 2: along the horizontal central line, respectively welding a top bracing support with the same wall thickness and length at one end of each of two ends of the horizontal direction of the wallboard, tying a construction line at the end part of each top bracing support, and arranging the top bracing supports at intervals of 2-3 m along the construction line;
and step 3: after the top support bracket and the vertical steel bar of the wall body are welded, the fixed bracket and the top support bracket are welded and connected along the horizontal direction;
and 4, step 4: marking the center position of the embedded part on the fixed support, and welding the middle part of the embedded part along the fixed support after determining that the position is correct;
and 5: when the fixed support and the embedded part are firmly connected by welding, welding screws are uniformly distributed on the fixed support;
step 6: punching holes on the template to ensure that the counter-pulling screw rod and the welding screw rod on the fixed support can penetrate out of the template;
and 7: closing the template, and fastening the screw rods outside the reserved template by using a pipe clamp and a screw cap;
and 8: after the template is further checked to be reinforced stably, concrete is poured and vibrated to be compact;
and step 9: and (4) removing the formwork after the concrete curing age reaches the standard, cutting the counter-pulling screw rod by using a grinding machine, and recovering the screw rod at the end part of the pull rod so as to be conveniently used next time and finish the operation.
Thewallboard embedded part complete construction method effectively solves the problem that the accuracy cannot be guaranteed when the quantity of the wallboard embedded parts is large. The method has the core idea that originally independent embedded parts are positioned in a mode of welding and fixing a support, and meanwhile, the embedded parts are connected to form a whole set for reinforcing. Compared with a single installation and fixation method of arranging each embedded part fluke to be equal to the wall thickness and forming a hole in the middle of the embedded part. The construction is more convenient and fast while the accuracy is ensured, the workload is greatly reduced, and the time is saved.
Compared with the traditional construction method for directly welding the embedded part and the horizontal rib, the method has the advantages that the installation accuracy is higher, and the phenomenon that the embedded part is not concave and uneven can not occur. Secondary reworking is effectively avoided, cost is saved, and construction period is shortened.
Meanwhile, the screws used in the wallboard embedded part complete construction method are all waste materials of the end parts of the counter-pulling screws cut during concrete form removal, so that the material value is fully exerted, and the wall plate embedded part can be repeatedly used.
